Gaming tournaments are exciting for certain players and are a widely-used form of casino promotion. Generally, a gaming tournament is a group event that a plurality of players pay (or otherwise qualify) to join. During a typical gaming tournament, the tournament players play a tournament game on individual electronic gaming machines (EGMs) to try to win tournament points. The tournament game has a static average expected point payout that represents the quantity of tournament points, on average, a tournament player will win for a play of the tournament game. The tournament players accumulate tournament points when they achieve winning outcomes for their plays of the tournament games. The tournament player(s) who has accumulated the most tournament points at the end of the tournament is the tournament winner. Certain tournaments have multiple rounds. Players are eliminated from round to round (e.g., eliminating players who don't accumulate enough tournament points) until the tournament winner remains.
There is a continuing need to provide new and exciting gaming tournaments to increase player enjoyment, entertainment, and excitement.
The present disclosure is directed to a gaming system and method providing a gaming tournament having a variable average expected point payout. Generally, during the gaming tournament, the gaming system enables each tournament player to play a tournament game at an EGM. The gaming system accumulates one or more tournament points for the tournament player when a play of the tournament game results in a winning outcome. At various points in time during the tournament, the gaming system increases or decreases an average expected point payout of the tournament game to change the tournament players' gaming experience.
This modification to the average expected point payout of the tournament game affects how many tournament points the player is likely to win, on average, for each play of the tournament game. Changing the average expected point payout of the tournament game during the tournament increases player enjoyment, entertainment, excitement, and anticipation. When the gaming system increases the average expected point payout of the tournament game, the players enjoy higher tournament point payouts and frenzied action. Conversely, when the gaming system decreases the average expected point payout of the tournament game, the players' anticipation levels rise as the players wait for the average expected point payout of the tournament game to increase.
More specifically, in one embodiment, the gaming system starts a gaming tournament for a plurality of tournament players. The gaming system enables each tournament player to play a tournament game on that tournament player's EGM. For each tournament player, for each play of the tournament game of that tournament player, the gaming system determines an outcome and determines and provides the tournament player any game award associated with the outcome. Each game award includes a quantity of one or more tournament points.
The gaming system monitors for the occurrence of any of a plurality of average expected point payout modification events and the occurrence of a tournament termination event. Until one of the average expected point payout modification events or the tournament termination occurs, the gaming system continues enabling each tournament player to play the tournament game on that tournament player's EGM.
Once the gaming system determines that one of the plurality of average expected point payout modification events occurs, the gaming system modifies (such as by increasing or decreasing) an average expected point payout of the tournament game. The gaming system then continues enabling each tournament player to play the tournament game (having the modified average expected point payout) on that tournament player's EGM.
Once the gaming system determines that the tournament termination event occurs, the gaming system stops enabling each tournament player to play the tournament game on that tournament player's EGM. The gaming system determines at least one tournament winner based on the quantities of tournament points the tournament players accumulated during the tournament. The gaming system provides a monetary tournament award to the at least one tournament winner, and ends the tournament.
Additional features and advantages are described herein, and will be apparent from, the following Detailed Description and the Figures.
The present disclosure is directed to a gaming system and method providing a gaming tournament having a variable average expected point payout. Generally, during the gaming tournament, the gaming system enables each tournament player to play a tournament game at an EGM. The gaming system accumulates one or more tournament points for the tournament player when a play of the tournament game results in a winning outcome. At various points in time during the tournament, the gaming system increases or decreases an average expected point payout of the tournament game to change the tournament players' gaming experience.
In operation of this embodiment, the process 100 begins and the gaming system starts a gaming tournament for a plurality of tournament players, as indicated by block 102. The gaming system enables each tournament player to play a tournament game on that tournament player's EGM, as indicated by block 104. For each tournament player, for each play of the tournament game of that tournament player, the gaming system determines an outcome and determines and provides the tournament player any game award associated with the outcome, as indicated by block 106. Each game award includes a quantity of one or more tournament points.
The gaming system monitors for the occurrence of any of a plurality of average expected point payout modification events and the occurrence of a tournament termination event, as indicated by diamonds 108 and 110, respectively. If none of the plurality of average expected point payout modification events have occurred, the process 100 returns to block 104 and the gaming system continues enabling each tournament player to play the tournament game on that tournament player's EGM. Similarly, if the tournament termination event has not occurred, the process 100 returns to block 104 and the gaming system continues enabling each tournament player to play the tournament game on that tournament player's EGM.
If the gaming system determines at diamond 108 that one of the plurality of average expected point payout modification events occurs, the gaming system modifies an average expected point payout of the tournament game, as indicated by block 112. The process 100 then returns to block 104, and the gaming system continues enabling each tournament player to play the tournament game (with the modified average expected point payout) on that tournament player's EGM.
If the gaming system determines at diamond 110 that the tournament termination event occurs, the gaming system stops enabling each tournament player to play the tournament game on that tournament player's EGM, as indicated by block 114. The gaming system determines at least one tournament winner based on the quantities of tournament points the tournament players accumulated during the gaming tournament, as indicated by block 116. The gaming system provides a monetary tournament award to the at least one tournament winner, as indicated by block 118, and the process 100 ends.
1. Tournament Characteristics
Players may enter or qualify for the gaming tournament in any suitable manner, depending on the embodiment. In certain embodiments, if a player achieves a designated outcome during play of a primary game or a bonus game, the gaming system qualifies the player for the gaming tournament. In other embodiments, if a player achieves a particular score during play of a primary game or a bonus game, the gaming system qualifies the player for the gaming tournament. In various embodiments, the gaming system qualifies the player for the gaming tournament upon an occurrence of a bonus triggering event during play of a primary game. In certain embodiments, the gaming system qualifies a player for the gaming tournament after the player has played a particular game for a designated period of time. In other embodiments, the gaming system qualifies a player for the gaming tournament after the player has played any combination of games for a designated period of time. In various embodiments, the gaming system enables a player to win entry into the gaming tournament via bonus game play. That is, in these embodiments, entry into the gaming tournament is an award that the player can win via play of the bonus game. In certain embodiments, the gaming system enables a player to win entry into the gaming tournament via primary game play. That is, in these embodiments, entry into the gaming tournament is an award that the player can win via play of the primary game. In other embodiments, the gaming system only enables a player to win entry into the gaming tournament if the player has previously qualified for a different tournament. In certain embodiments, the gaming system enables a player to pay a fee to enter the gaming tournament (such as via an EGM, a kiosk, or a cashier or other casino employee). In various embodiments the gaming system enables a player to redeem a promotion the gaming establishment sent the player (e.g., via email, postal mail, or text message) to qualify for the gaming tournament.
In various embodiments, the gaming system only enables players to enter or qualify for the gaming tournament during a tournament qualification period. For example, the gaming system may only enable players to enter or qualify for the gaming tournament on a particular day or other period of time before the start of the gaming tournament.
In other embodiments, the gaming system qualifies a player for the gaming tournament based on one or more characteristics from the player's player tracking account. For instance, in one example embodiment, the gaming system qualifies all players having a particular player tracking rank or level (e.g., Platinum Level players) for the gaming tournament. In another example embodiment, the gaming system qualifies all players with newly-registered player tracking accounts for the gaming tournament. In another example embodiment, the gaming system qualifies a player for the gaming tournament on the player's birthday or anniversary of registering for her player tracking account. In another example embodiment in which a player accrues player tracking points through game play, the gaming system qualifies the player for the gaming tournament when the player's accrued player tracking point balance reaches one of a plurality of different threshold levels.
The above-described ways in which the gaming system may qualify a player for a tournament are merely examples, and the present disclosure contemplates any suitable manner of qualifying players, such as any of those described in U.S. Pat. Nos. 7,684,874 or 9,111,416, which are incorporated herein by reference.
The gaming system starts the gaming tournament upon an occurrence of a suitable tournament start event, such as the arrival of a particular date and time; the qualification of a designated quantity of players for the gaming tournament (e.g., a maximum quantity of players); a tournament award pool reaching a designated amount; or an occurrence of a triggering event during game play. These tournament start events are merely examples, and the present disclosure contemplates any suitable tournament start event, such as any of those described in U.S. Pat. Nos. 7,684,874 or 9,111,416, which are incorporated herein by reference.
The gaming system ends the gaming tournament upon an occurrence of a suitable tournament termination event, such as the elapsing of a designated period of time (e.g., a tournament that ends 60 minutes from when it starts); the tournament players having collectively completed a designated quantity of plays of the tournament game (e.g., a tournament that ends after the tournament players have collectively completed 10,000 plays of the tournament game); the occurrence of a designated outcome for a play of the tournament game (e.g., a tournament that ends when a play of the tournament game results in a jackpot outcome); or one tournament player accumulating a designated quantity of tournament points (e.g., a tournament that ends when one tournament player accumulates 1,000 tournament points). These tournament termination events are merely examples, and the present disclosure contemplates any suitable tournament termination event, such as any of those described in U.S. Pat. Nos. 7,684,874 or 9,111,416, which are incorporated herein by reference.
The tournament game may be any suitable game, such as a reel-based game, a card game (such as poker or blackjack), a keno game, a bingo game, or a roulette game. These tournament games are merely examples, and the present disclosure contemplates any suitable tournament games, such as any of those described in U.S. Pat. Nos. 7,684,874 or 9,111,416, which are incorporated herein by reference.
In certain embodiments, the average expected point payout for the tournament game is the same for all tournament players, both initially and after being modified. In various embodiments, the gaming system may modify the average expected point payout of the tournament game for different players at different times during the tournament while ensuring that the overall average expected point payout is the same for all players over the course of the entire tournament. In certain embodiments, the gaming system increases the average expected point payout for players lagging behind others to enable those players to catch up and keep the tournament competitive. In various embodiments, the gaming system temporarily increases the average expected point payout for a player when the player meets a certain condition.
The actual point payout for the tournament game may, however, differ among players. Certain players may play a “hot” EGM that pays many high awards while others may not.
In other embodiments, the average expected point payout for the tournament game may differ for different players of the same tournament.
The gaming system may determine the tournament winner in any suitable manner. In certain embodiments in which the gaming tournament has a single tournament winner, the gaming system designates the player who accumulated the most tournament points during the gaming tournament as the tournament winner. In other embodiments in which the gaming tournament has a designated quantity of tournament winners, the gaming system ranks the tournament players according to how many tournament points the players have accumulated, and selects the designated quantity of tournament players atop the list (i.e., having the most accumulated tournament points). These ways to determine the tournament winner(s) are merely examples, and the present disclosure contemplates any suitable ways to determine the tournament winner(s), such as any of those described in U.S. Pat. Nos. 7,684,874 or 9,111,416, which are incorporated herein by reference.
The tournament award may be any suitable award, such as: (1) monetary credits or currency; (2) non-monetary credits or currency; (3) a modifier (e.g., a multiplier) used to modify one or more awards; (4) one or more free plays of a game; (5) one or more plays of a bonus game (e.g., a free spin of an award wheel); (6) one or more lottery based awards (e.g., one or more lottery or drawing tickets); (7) a wager match for one or more plays of the a wagering game; (8) an increase in an average expected payback percentage of a bonus game and/or an average expected payback percentage of a primary game for one or more plays; (9) one or more comps (such as a free meal or a free night's stay at a hotel); (10) one or more bonus or promotional credits usable for online play; (11) one or more player tracking points; (12) a multiplier for player tracking points; (13) an increase in a membership or player tracking level; (14) one or more coupons or promotions usable within a gaming establishment or outside of the gaming establishment (e.g., a 20% off coupon for use at a retail store or a promotional code providing a deposit match for use at an online casino); (15) an access code usable to unlock content on the Internet; (16) a progressive award; (17) a high value product or service (such as a car); and/or (18) a low value product or service (such as a teddy bear).
The above-listed tournament awards are merely examples, and the present disclosure contemplates any suitable tournament awards, such as any of those described in U.S. Pat. Nos. 7,684,874 or 9,111,416, which are incorporated herein by reference.
2. Average Expected Point Payout Modification Events
An average expected point payout modification event may be any suitable event, such as but not limited to: (1) the expiration of a designated period of time following the start of the gaming tournament (e.g., the expiration of the first 10 minutes of the gaming tournament, the expiration of the second 10 minutes of the gaming tournament, and so on); (2) the occurrence of a triggering event during tournament game play (e.g., a play of the tournament game resulting in a particular outcome); (3) the tournament players having collectively completed a designated quantity of plays of the tournament game (e.g., the tournament players having collectively completed 10,000 plays of the tournament game); (4) a single tournament player having completed a designated quantity of plays of the tournament game (e.g., one tournament player having completed 250 plays of the tournament game); (5) the tournament players having collectively accumulated a designated quantity of tournament points during the gaming tournament (e.g., the tournament players having collectively accumulated 100,000 tournament points during the gaming tournament); (6) a tournament player having accumulated a designated quantity of tournament points during the gaming tournament (e.g., one tournament player having accumulated 5,000 tournament points during the gaming tournament); (7) the occurrence of a particular time (e.g., 5:00 PM); (8) the occurrence of a particular date and time (e.g., July 4 at Noon); (9) a random mystery event; (10) a tournament operator-initiated event; or (11) any combination thereof. Multiple different average expected point payout modification events may occur during a single tournament.
Each average expected point payout modification event is associated with a tournament game modification. When an average expected point payout modification event occurs, the gaming system implements the tournament game modification associated with that average expected point payout modification event. Implementing the tournament game modification changes (i.e., increases or decreases) the current average expected point payout of the tournament game. Different example ways of modifying the tournament game to change the average expected point payout are described below in Section 3.
In certain embodiments, an average expected point payout event is associated with a plurality of different tournament game modifications rather than a single tournament game modification. In one of these embodiments, when the average expected point payout event occurs, the gaming system determines one of the tournament game modifications and modifies the tournament according to that particular tournament game modification. In another of these embodiments, when the average expected point payout event occurs, the gaming system modifies the tournament according to all of those particular tournament game modifications
Certain tournament game modifications last for a designated period, such as a designated period of time or a designated quantity of plays of the tournament game. Other tournament game modifications last until another average expected point payout modification event occurs. Other tournament game modifications last for a designated period or until another average expected point payout modification event occurs, whichever happens first. Some tournament game modifications last for a randomly-determined period of time.
The gaming tournament may include any suitable quantity of one or more average expected point payout modification events. In certain embodiments including multiple average expected point payout modification events, any average expected point payout modification event can occur at any time. In other embodiments including multiple average expected point payout modification events, the average expected point payout modification events must occur according to a particular order such that only one average expected point payout modification event can occur at any given point in time.
For certain average expected point payout modification events, once that average expected point payout modification event occurs, that average expected point payout modification event cannot occur again during the tournament. For other average expected point payout modification events, that average expected point payout modification event can occur up to a designated quantity of one or more times during the tournament. For other average expected point payout modification events, those average expected point payout modification event can occur an unlimited quantity of times during the tournament.
3. Modifying the Average Expected Point Payout of the Tournament Game
As mentioned above, each average expected point payout modification event is associated with a tournament game modification. When an average expected point payout modification event occurs, the gaming system implements the tournament game modification associated with that average expected point payout modification event. Certain examples of how the gaming system modifies the tournament game's average expected point payout after the occurrences of certain average expected point payout modification events are described below. There are merely examples, and the present disclosure contemplates any other suitable ways of modifying the average expected point payout of the tournament game.
3.1 Increasing the Average Expected Point Payout of a Five-Card Draw Poker Tournament Game by Selecting Better Initial Hands as the Gaming Tournament Progresses
In certain embodiments, the tournament game is a five-card draw poker game and the gaming system increases the average expected point payout of the five-card draw poker tournament game by selecting better initial hands as the gaming tournament progresses.
A play of this five-card draw poker tournament game (before any modification of the average expected point payout) generally proceeds as follows:
In these embodiments, the gaming system increases the average expected point payout of the five-card draw poker tournament game by selecting better initial hands as the gaming tournament progresses. In other words, after a certain point in time during the gaming tournament, rather than randomly selecting the initial hand of five cards, the gaming system selects all five cards of the initial hand such that the initial hand includes at least one random card and two or more cards associated with a particular poker ranking. For example, after a certain point in time, each initial hand for a play of the five-card draw poker tournament game includes four cards to a Royal Flush (e.g., A♥, K♥, Q♥, and J♥) and one random card. This increases the average expected point payout of this play of the five-card draw poker tournament game because it significantly increases the player's odds of hitting the Royal Flush (as compared to a randomly-selected initial five card hand).
Table 1 below illustrates an example embodiment in which the gaming system randomly selects the player's initial five-card hand at the outset of the gaming tournament and, as the gaming tournament progresses, selects better initial five-card hands. This example embodiment includes five average expected point payout modification events (for a 60 minute tournament): (1) a first average expected point payout modification event that occurs 10 minutes after the start of the gaming tournament, (2) a second average expected point payout modification event that occurs 20 minutes after the start of the gaming tournament, (3) a third average expected point payout modification event that occurs 30 minutes after the start of the gaming tournament, (4) a fourth average expected point payout modification event that occurs 40 minutes after the start of the gaming tournament, and (5) a fifth average expected point payout modification event that occurs 50 minutes after the start of the gaming tournament.
When the first average expected point payout modification event occurs, the gaming system modifies the tournament game such that each subsequent initial hand until the second average expected point payout modification event occurs includes a matching Pair of cards and three randomly-determined cards.
When the second average expected point payout modification event occurs, the gaming system modifies the tournament game such that each subsequent initial hand until the third average expected point payout modification event occurs includes four cards to a Straight and one randomly-determined card.
When the third average expected point payout modification event occurs, the gaming system modifies the tournament game such that each subsequent initial hand until the fourth average expected point payout modification event occurs includes four cards to a Flush and one randomly-determined card.
When the fourth average expected point payout modification event occurs, the gaming system modifies the tournament game such that each subsequent initial hand until the fifth average expected point payout modification event occurs includes two matching Pairs of cards (i.e., four cards to a Full House) and one randomly-determined card.
When the fifth average expected point payout modification event occurs, the gaming system modifies the tournament game such that each subsequent initial hand until the gaming tournament ends includes four cards to a Royal Flush and one randomly-determined card.
This is merely one example embodiment. The gaming system may provide any suitable initial hands following the occurrences of the average expected point payout modification events to increase the average expected point payout of the tournament game by any suitable amount.
This concept may be used for other games as well. For example, in one embodiment, the tournament game is a spinning-reel type game and the gaming system increases the average expected point payout of the spinning-reel type tournament game by using more lucrative reel sets as the tournament progresses and average expected point payout modification events occur. In another example embodiment, the tournament game is a keno game and the gaming system increases the average expected point payout of the keno tournament game by enabling the player to choose more numbers as the tournament progresses and average expected point payout modification events occur.
3.2 Increasing the Average Expected Point Payout of a Tournament Game by Randomly Providing Multipliers for Plays of the Tournament Game
In certain embodiments, gaming system increases the average expected point payout of a tournament game by randomly providing multipliers for plays of the tournament game. The gaming system uses a provided multiplier to modify any game award (i.e., quantity of tournament points) won for that play of the tournament game.
In one embodiment, there is only one multiplier—referred to as a designated multiplier—that the gaming system can randomly provide during the gaming tournament. In this embodiment, the probability of providing the designated multiplier for a play of the tournament game increases as the gaming tournament progresses. Thus, in this embodiment, if the gaming system randomly determines (based on the appropriate probability of providing the designated multiplier at that time) to provide the designated multiplier for a play of the tournament game, the gaming system uses the designated multiplier to modify any game awards for that play.
Table 2 below illustrates an example embodiment in which the gaming system can randomly provide a 5× multiplier during a tournament and the probability of providing the 5× multiplier for a play of the tournament game increases from a minimum of 0% to a maximum of 75% as the gaming tournament progresses. This example embodiment includes five average expected point payout modification events: (1) a first average expected point payout modification event that occurs 10 minutes after the start of the gaming tournament, (2) a second average expected point payout modification event that occurs 20 minutes after the start of the gaming tournament, (3) a third average expected point payout modification event that occurs 30 minutes after the start of the gaming tournament, (4) a fourth average expected point payout modification event that occurs 40 minutes after the start of the gaming tournament, and (5) a fifth average expected point payout modification event that occurs 50 minutes after the start of the gaming tournament.
Initially, the gaming system cannot provide the 5× multiplier. That is, the gaming system has a 0% chance of providing the 5× multiplier for a play of the tournament game.
When the first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the second average expected point payout modification event occurs, the gaming system has a 15% chance of providing the 5× multiplier.
When the second average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the third average expected point payout modification event occurs, the gaming system has a 30% chance of providing the 5× multiplier.
When the third average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the fourth average expected point payout modification event occurs, the gaming system has a 45% chance of providing the 5× multiplier.
When the fourth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the fifth average expected point payout modification event occurs, the gaming system has a 60% chance of providing the 5× multiplier.
When the fifth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the gaming tournament ends, the gaming system has a 75% chance of providing the 5× multiplier.
This is merely one example embodiment. The multiplier may have any suitable value, the probabilities may be any suitable values, and the average expected point payout modification events may be any suitable events.
In another embodiment, the probability of providing a multiplier does not change throughout the gaming tournament. There are, however, a plurality of different available multipliers, and the probability that the gaming system will select larger multipliers increases as the gaming tournament progresses. Thus, in this embodiment, if the gaming system randomly determines (based on the static probability of providing a multiplier) to provide a multiplier for a play of the tournament game, the gaming system randomly selects one of the plurality of multipliers (based on the probabilities of being selected associated with the multipliers at that time) and uses the selected multiplier to modify any game awards for that play.
Table 3 below illustrates an example embodiment in which the probability of providing a multiplier is 15%, the largest multiplier's probability of being selected increases from 0% to 75% as the gaming tournament progresses, and the smallest multiplier's probability of being selected decreases from 100% to 5% as the gaming tournament progresses. This example embodiment includes five average expected point payout modification events: (1) a first average expected point payout modification event that occurs 10 minutes after the start of the gaming tournament, (2) a second average expected point payout modification event that occurs 20 minutes after the start of the gaming tournament, (3) a third average expected point payout modification event that occurs 30 minutes after the start of the gaming tournament, (4) a fourth average expected point payout modification event that occurs 40 minutes after the start of the gaming tournament, and (5) a fifth average expected point payout modification event that occurs 50 minutes after the start of the gaming tournament.
Initially, if the gaming system determines to provide a multiplier, the gaming system provides the 2× multiplier. That is, the gaming system has a 100% chance of providing the 2× multiplier if it determines to provide a multiplier for a play of the tournament game.
When the first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the second average expected point payout modification event occurs, if the gaming system determines to provide a multiplier, the gaming system has a 75% chance of selecting the 2× multiplier, a 20% chance of selecting the 3× multiplier, and a 5% chance of selecting the 5× multiplier.
When the second average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the third average expected point payout modification event occurs, if the gaming system determines to provide a multiplier, the gaming system has a 50% chance of selecting the 2× multiplier, a 35% chance of selecting the 3× multiplier, and a 15% chance of selecting the 5× multiplier.
When the third average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the fourth average expected point payout modification event occurs, if the gaming system determines to provide a multiplier, the gaming system has a 25% chance of selecting the 2× multiplier, a 50% chance of selecting the 3× multiplier, and a 25% chance of selecting the 5× multiplier.
When the fourth first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the fifth average expected point payout modification event occurs, if the gaming system determines to provide a multiplier, the gaming system has a 15% chance of selecting the 2× multiplier, a 35% chance of selecting the 3× multiplier, and a 50% chance of selecting the 5× multiplier.
When the fifth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the gaming tournament ends, if the gaming system determines to provide a multiplier, the gaming system has a 5% chance of selecting the 2× multiplier, a 20% chance of selecting the 3× multiplier, and a 75% chance of selecting the 5× multiplier.
This is merely one example embodiment. The multipliers may have any suitable values, the probabilities may be any suitable values, and the average expected point payout modification events may be any suitable events.
In another embodiment, the probability of providing a multiplier increases as the gaming tournament progresses. In this embodiment, there are a plurality of different available multipliers, and the probability that the gaming system will select larger multipliers increases as the gaming tournament progresses. Thus, in this embodiment, if the gaming system randomly determines (based on the appropriate probability of providing a multiplier at that time) to provide a multiplier for a play of the tournament game, the gaming system randomly selects one of the plurality of multipliers (based on the probabilities of being selected associated with the multipliers at that time) and uses the selected multiplier to modify any game awards for that play.
Table 4 below illustrates an example embodiment in which the probability of providing a multiplier increases from 0% to 75% as the gaming tournament progresses, the largest multiplier's probability of being selected increases from 0% to 75% as the gaming tournament progresses, and the smallest multiplier's probability of being selected decreases from 100% to 5% as the gaming tournament progresses. This example embodiment includes five average expected point payout modification events: (1) a first average expected point payout modification event that occurs 10 minutes after the start of the gaming tournament, (2) a second average expected point payout modification event that occurs 20 minutes after the start of the gaming tournament, (3) a third average expected point payout modification event that occurs 30 minutes after the start of the gaming tournament, (4) a fourth average expected point payout modification event that occurs 40 minutes after the start of the gaming tournament, and (5) a fifth average expected point payout modification event that occurs 50 minutes after the start of the gaming tournament.
Initially, the gaming system cannot provide a multiplier for a play of the tournament game. That is, the gaming system has a 0% chance of providing a multiplier for a play of the tournament game.
When the first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the second average expected point payout modification event occurs, the gaming system has a 15% chance of providing a multiplier and, if the gaming system determines to provide a multiplier, the gaming system has a 75% chance of selecting the 2× multiplier, a 20% chance of selecting the 3× multiplier, and a 5% chance of selecting the 5× multiplier.
When the second average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the third average expected point payout modification event occurs, the gaming system has a 30% chance of providing a multiplier and, if the gaming system determines to provide a multiplier, the gaming system has a 50% chance of selecting the 2× multiplier, a 35% chance of selecting the 3× multiplier, and a 15% chance of selecting the 5× multiplier.
When the third average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the fourth average expected point payout modification event occurs, the gaming system has a 45% chance of providing a multiplier and, if the gaming system determines to provide a multiplier, the gaming system has a 25% chance of selecting the 2× multiplier, a 50% chance of selecting the 3× multiplier, and a 25% chance of selecting the 5× multiplier.
When the fourth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the fifth average expected point payout modification event occurs, the gaming system has a 60% chance of providing a multiplier and, if the gaming system determines to provide a multiplier, the gaming system has a 15% chance of selecting the 2× multiplier, a 35% chance of selecting the 3× multiplier, and a 50% chance of selecting the 5× multiplier.
When the fifth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the gaming tournament ends, the gaming system has a 75% chance of providing a multiplier and, if the gaming system determines to provide a multiplier, the gaming system has a 5% chance of selecting the 2× multiplier, a 20% chance of selecting the 3× multiplier, and a 75% chance of selecting the 5× multiplier.
This is merely one example embodiment. The multiplier may have any suitable value, the probabilities may be any suitable values, and the average expected point payout modification events may be any suitable events.
3.3 Increasing the Average Expected Point Payout of a Five-Card Draw Poker Tournament Game by Internally Selecting a Plurality of Initial Hands and Dealing the Tournament Player the Best of the Plurality of Initial Hands
In certain embodiments, the tournament game is a five-card draw poker game and the gaming system increases the average expected point payout of the five-card draw poker tournament game by internally selecting a plurality of initial hands and dealing the player the best of the plurality of initial hands.
A play of this five-card draw poker tournament game (before any modification of the average expected point payout) generally proceeds as follows:
In these embodiments, the gaming system increases the average expected point payout of the five-card draw poker tournament game by, for each play of the five-card draw poker tournament game following an occurrence of an average expected point payout modification event: (1) internally selecting two or more initial hands from different 52-card virtual decks of standard cards, (2) determining which of the two or more initial hands has a highest expected point value, and (3) dealing the tournament player the initial hand having the highest expected point value. Play then proceeds as described above. Increasing the pool of hands from which the gaming system selects the best hand to deal to the tournament player will, over time, statistically give the tournament player better winning hands than if the gaming system simply provided the player the first-selected initial hand.
Table 5 below illustrates an example embodiment in which the quantity of hands the gaming system internally selects—and from which the gaming system selects and deals the initial hand to the tournament player—increases as the gaming tournament progresses. This example embodiment includes five average expected point payout modification events: (1) a first average expected point payout modification event that occurs 10 minutes after the start of the gaming tournament, (2) a second average expected point payout modification event that occurs 20 minutes after the start of the gaming tournament, (3) a third average expected point payout modification event that occurs 30 minutes after the start of the gaming tournament, (4) a fourth average expected point payout modification event that occurs 40 minutes after the start of the gaming tournament, and (5) a fifth average expected point payout modification event that occurs 50 minutes after the start of the gaming tournament.
Initially, as described above, the gaming system internally selects a single initial hand and provides the player that initial hand as the player's initial hand.
When the first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the second average expected point payout modification event occurs, the gaming system internally selects two initial hands and provides the best of the two initial hands to the player as the player's initial hand.
When the second average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the third average expected point payout modification event occurs, the gaming system internally selects five initial hands and provides the best of the five initial hands to the player as the player's initial hand.
When the third average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the fourth average expected point payout modification event occurs, the gaming system internally selects ten initial hands and provides the best of the ten initial hands to the player as the player's initial hand.
When the fourth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the fifth average expected point payout modification event occurs, the gaming system internally selects fifteen initial hands and provides the best of the fifteen initial hands to the player as the player's initial hand.
When the fifth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the gaming tournament ends, the gaming system internally selects twenty initial hands and provides the best of the twenty initial hands to the player as the player's initial hand.
This is merely one example embodiment. The quantities of internally-selected initial hands may be any suitable quantities and the average expected point payout modification events may be any suitable events.
In other embodiments, instead of (or in addition to) internally selecting a quantity of initial hands, when the player discards a card, the gaming system internally selects a quantity of replacement cards and chooses the best of those replacement cards to replace the discarded card.
This concept may be used for other games as well. For example, in one embodiment, the tournament game is a spinning-reel type game and the gaming system increases the average expected point payout of the spinning-reel type tournament game by internally conducting a plurality of reel spins and displaying to the player the best of the plurality of reel spins (i.e., the one the results in the player winning the most tournament points). In another example embodiment, the tournament game is a keno game and the gaming system increases the average expected point payout of the keno tournament game by internally conducting a plurality of number draws and displaying to the player the best of the plurality of number draws (i.e., the one that results in the player winning the most tournament points).
3.4 Increasing the Average Expected Point Payout of a Tournament Game by Randomly Providing Tournament Point Awards
In certain embodiments, gaming system increases the average expected point payout of a tournament game by randomly providing tournament point awards. The gaming system randomly provides the tournament point awards independent of the tournament games that the player plays. Put differently, whether the gaming system randomly provides a player a tournament point award is not based on any event that occurs during the tournament player's play(s) of the tournament game.
In one embodiment, there is only one tournament point award—referred to as the designated tournament point award—that the gaming system can randomly provide during the gaming tournament. In this embodiment, the probability of providing the designated tournament point award increases as the gaming tournament progresses. Thus, in this embodiment, if the gaming system randomly determines (based on the appropriate probability of providing the designated tournament point award at that time) to provide the designated tournament point award, the gaming system provides the designated tournament point award.
Table 6 below illustrates an example embodiment in which the gaming system can randomly provide a 50 tournament point award during a tournament and the probability of providing the 50 tournament point award increases from a minimum of 0% to a maximum of 75% as the gaming tournament progresses. This example embodiment includes five average expected point payout modification events: (1) a first average expected point payout modification event that occurs 10 minutes after the start of the gaming tournament, (2) a second average expected point payout modification event that occurs 20 minutes after the start of the gaming tournament, (3) a third average expected point payout modification event that occurs 30 minutes after the start of the gaming tournament, (4) a fourth average expected point payout modification event that occurs 40 minutes after the start of the gaming tournament, and (5) a fifth average expected point payout modification event that occurs 50 minutes after the start of the gaming tournament.
Initially, the gaming system cannot provide the 50 tournament point award. That is, the gaming system has a 0% chance of providing the 50 tournament point award.
When the first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the second average expected point payout modification event occurs, the gaming system has a 15% chance of providing the 50 tournament point award.
When the second average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the third average expected point payout modification event occurs, the gaming system has a 30% chance of providing the 50 tournament point award.
When the third average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the fourth average expected point payout modification event occurs, the gaming system has a 45% chance of providing the 50 tournament point award.
When the fourth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the fifth average expected point payout modification event occurs, the gaming system has a 60% chance of providing the 50 tournament point award.
When the fifth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the tournament ends, the gaming system has a 75% chance of providing the 50 tournament point award.
This is merely one example embodiment. The tournament point award may have any suitable value, the probabilities may be any suitable values, and the average expected point payout modification events may be any suitable events.
In another embodiment, the probability of providing a tournament point award does not change throughout the gaming tournament. There are, however, a plurality of different available tournament point awards, and the probability that the gaming system will select larger tournament point awards increases as the gaming tournament progresses. Thus, in this embodiment, if the gaming system randomly determines (based on the static probability of providing a tournament point award) to provide a tournament point award, the gaming system randomly selects one of the plurality of tournament point awards (based on the probabilities of being selected associated with the tournament point awards at that time) and provides the selected tournament point award.
Table 7 below illustrates an example embodiment in which the probability of providing a tournament point award is 15%, the largest tournament point award's probability of being selected increases from 0% to 75% as the gaming tournament progresses, and the smallest tournament point award's probability of being selected decreases from 100% to 5% as the gaming tournament progresses. This example embodiment includes five average expected point payout modification events: (1) a first average expected point payout modification event that occurs 10 minutes after the start of the gaming tournament, (2) a second average expected point payout modification event that occurs 20 minutes after the start of the gaming tournament, (3) a third average expected point payout modification event that occurs 30 minutes after the start of the gaming tournament, (4) a fourth average expected point payout modification event that occurs 40 minutes after the start of the gaming tournament, and (5) a fifth average expected point payout modification event that occurs 50 minutes after the start of the gaming tournament.
Initially, if the gaming system determines to provide a tournament point award, the gaming system provides the 20 tournament point award. That is, the gaming system has a 100% chance of providing the 20 tournament point award if it determines to provide a tournament point award.
When the first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the second average expected point payout modification event occurs, if the gaming system determines to provide a tournament point award, the gaming system has a 75% chance of selecting the 20 tournament point award, a 20% chance of selecting the 30 tournament point award, and a 5% chance of selecting the 50 tournament point award.
When the second average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the third average expected point payout modification event occurs, if the gaming system determines to provide a tournament point award, the gaming system has a 50% chance of selecting the 20 tournament point award, a 35% chance of selecting the 30 tournament point award, and a 15% chance of selecting the 50 tournament point award.
When the third average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the fourth average expected point payout modification event occurs, if the gaming system determines to provide a tournament point award, the gaming system has a 25% chance of selecting the 20 tournament point award, a 50% chance of selecting the 30 tournament point award, and a 25% chance of selecting the 50 tournament point award.
When the fourth first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the fifth average expected point payout modification event occurs, if the gaming system determines to provide a tournament point award, the gaming system has a 15% chance of selecting the 20 tournament point award, a 35% chance of selecting the 30 tournament point award, and a 50% chance of selecting the 50 tournament point award.
When the fifth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the gaming tournament ends, if the gaming system determines to provide a tournament point award, the gaming system has a 5% chance of selecting the 20 tournament point award, a 20% chance of selecting the 30 tournament point award, and a 75% chance of selecting the 50 tournament point award.
This is merely one example embodiment. The tournament point awards may have any suitable value, the probabilities may be any suitable values, and the average expected point payout modification events may be any suitable events.
In another embodiment, the probability of providing a tournament point award increases as the gaming tournament progresses. In this embodiment there are a plurality of different available tournament point awards, and the probability that the gaming system will select larger tournament point awards increases as the gaming tournament progresses. Thus, in this embodiment, if the gaming system randomly determines (based on the appropriate probability of providing a tournament point award at that time) to provide a tournament point award, the gaming system randomly selects one of the plurality of tournament point awards (based on the probabilities of being selected associated with the tournament point awards at that time) and provides the selected tournament point award.
Table 8 below illustrates an example embodiment in which the probability of providing a tournament point award increases from 0% to 75% as the gaming tournament progresses, the largest tournament point award's probability of being selected increases from 0% to 75% as the gaming tournament progresses, and the smallest tournament point award's probability of being selected decreases from 100% to 5% as the gaming tournament progresses. This example embodiment includes five average expected point payout modification events: (1) a first average expected point payout modification event that occurs 10 minutes after the start of the gaming tournament, (2) a second average expected point payout modification event that occurs 20 minutes after the start of the gaming tournament, (3) a third average expected point payout modification event that occurs 30 minutes after the start of the gaming tournament, (4) a fourth average expected point payout modification event that occurs 40 minutes after the start of the gaming tournament, and (5) a fifth average expected point payout modification event that occurs 50 minutes after the start of the gaming tournament.
Initially, the gaming system cannot provide a tournament point award. That is, the gaming system has a 0% chance of providing a tournament point award.
When the first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the second average expected point payout modification event occurs, the gaming system has a 15% chance of providing a tournament point award and, if the gaming system determines to provide a tournament point award, the gaming system has a 75% chance of selecting the 20 tournament point award, a 20% chance of selecting the 30 tournament point award, and a 5% chance of selecting the 50 tournament point award.
When the second average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the third average expected point payout modification event occurs, the gaming system has a 30% chance of providing a tournament point award and, if the gaming system determines to provide a tournament point award, the gaming system has a 50% chance of selecting the 20 tournament point award, a 35% chance of selecting the 30 tournament point award, and a 15% chance of selecting the 50 tournament point award.
When the third average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the fourth average expected point payout modification event occurs, the gaming system has a 45% chance of providing a tournament point award and, if the gaming system determines to provide a tournament point award, the gaming system has a 25% chance of selecting the 20 tournament point award, a 50% chance of selecting the 30 tournament point award, and a 25% chance of selecting the 50 tournament point award.
When the fourth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the fifth average expected point payout modification event occurs, the gaming system has a 60% chance of providing a tournament point award and, if the gaming system determines to provide a tournament point award, the gaming system has a 15% chance of selecting the 20 tournament point award, a 35% chance of selecting the 30 tournament point award, and a 50% chance of selecting the 50 tournament point award.
When the fifth average expected point payout modification event occurs, the gaming system modifies the tournament game such that, until the gaming tournament ends, the gaming system has a 75% chance of providing a tournament point award and, if the gaming system determines to provide a tournament point award, the gaming system has a 5% chance of selecting the 20 tournament point award, a 20% chance of selecting the 30 tournament point award, and a 75% chance of selecting the 50 tournament point award.
This is merely one example embodiment. The tournament point awards may have any suitable value, the probabilities may be any suitable values, and the average expected point payout modification events may be any suitable events.
In certain embodiments, if the gaming system determines to provide a tournament point award, the gaming system does not actually provide the tournament point award until the gaming system receives a particular input from the tournament player. For instance, in one example embodiment, when the gaming system determines to provide a tournament point award, the gaming system displays an indicator that represents the tournament point award (such as a pop-up bubble) on the display device of the tournament player's EGM. The gaming system provides the tournament player the tournament point award only if the tournament player's EGM receives a designated input via an input device, such as a touch of the displayed indicator via the touch screen. In this example embodiment, the gaming system does not provide the tournament player the tournament point award if the tournament player's EGM does not receive the designated input within a certain period of time.
3.5 Decreasing the Average Expected Point Payout of a Tournament Game by Removing a Feature from the Tournament Game
In certain embodiments, the gaming system decreases the average expected point payout of a tournament game by removing a feature from the tournament game (such as a prior modification to the tournament game). Table 9 below illustrates an example embodiment in which the gaming system can initially randomly provide a 5× multiplier during a tournament, loses that ability, and later regains that ability. This example embodiment includes two average expected point payout modification events: (1) a first average expected point payout modification event that occurs 10 minutes after the start of the gaming tournament, and (2) a second average expected point payout modification event that occurs 50 minutes after the start of the gaming tournament.
Initially, the gaming system has a 25% chance of providing a multiplier for each play of the tournament game.
When the first average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the second average expected point payout modification event occurs, the gaming system has a 0% chance of providing a multiplier.
When the second average expected point payout modification event occurs, the gaming system modifies the tournament game such that, for each subsequent play of the tournament game until the gaming tournament ends, the gaming system has a 75% chance of providing a multiplier.
This is merely one example embodiment. The multiplier may have any suitable value, the probabilities may be any suitable values, and the average expected point payout modification events may be any suitable events.
3.6 Increasing the Average Expected Point Payout of a Tournament Game by Modifying the Paytable of the Tournament Game
In certain embodiments, the gaming system increases the average expected point payout of a tournament game by modifying the paytable of the tournament game. The gaming system may do so in any of a variety of manners, such as by increasing the award associated with one or more winning outcomes in the paytable, increasing the probability of occurrence of one or more winning outcomes in the paytable, adding new winning outcomes to the paytable, or using a different paytable having one of these features.
3.7 Decreasing the Average Expected Point Payout of a Tournament Game by Modifying the Paytable of the Tournament Game
Conversely, in certain embodiments, the gaming system decreases the average expected point payout of a tournament game by modifying the paytable of the tournament game. The gaming system may do so in any of a variety of manners, such as by decreasing the award associated with one or more winning outcomes in the paytable, decreasing the probability of occurrence of one or more winning outcomes in the paytable, removing winning outcomes from the paytable, or using a different paytable having one of these features.

One, more than one, or each of the functions of the central server, central controller, or remote host may be performed by the at least one processor of the EGM (or personal computing device). Further, one, more than one, or each of the functions of the at least one processor of the EGM (or personal computing device) may be performed by the at least one processor of the central server, central controller, or remote host.
In certain such embodiments, computerized instructions for controlling any games (such as any primary or base games and/or any secondary or bonus games) displayed by the EGM (or personal computing device) are executed by the central server, central controller, or remote host. In such “thin client” embodiments, the central server, central controller, or remote host remotely controls any games (or other suitable interfaces) displayed by the EGM (or personal computing device), and the EGM (or personal computing device) is utilized to display such games (or suitable interfaces) and to receive one or more inputs or commands. In other such embodiments, computerized instructions for controlling any games displayed by the EGM (or personal computing device) are communicated from the central server, central controller, or remote host to the EGM (or personal computing device) and are stored in at least one memory device of the EGM (or personal computing device). In such “thick client” embodiments, the at least one processor of the EGM (or personal computing device) executes the computerized instructions to control any games (or other suitable interfaces) displayed by the EGM (or personal computing device).
In various embodiments in which the gaming system includes a plurality of EGMs (or personal computing devices), one or more of the EGMs (or personal computing devices) are thin client EGMs (or personal computing devices) and one or more of the EGMs (or personal computing devices) are thick client EGMs (or personal computing devices). In other embodiments in which the gaming system includes one or more EGMs (or personal computing devices), certain functions of one or more of the EGMs (or personal computing devices) are implemented in a thin client environment, and certain other functions of one or more of the EGMs (or personal computing devices) are implemented in a thick client environment. In one such embodiment in which the gaming system includes an EGM (or personal computing device) and a central server, central controller, or remote host, computerized instructions for controlling any primary or base games displayed by the EGM (or personal computing device) are communicated from the central server, central controller, or remote host to the EGM (or personal computing device) in a thick client configuration, and computerized instructions for controlling any secondary or bonus games or other functions displayed by the EGM (or personal computing device) are executed by the central server, central controller, or remote host in a thin client configuration.
In certain embodiments in which the gaming system includes: (a) an EGM (or personal computing device) configured to communicate with a central server, central controller, or remote host through a data network; and/or (b) a plurality of EGMs (or personal computing devices) configured to communicate with one another through a data network, the data network is a local area network (LAN) in which the EGMs (or personal computing devices) are located substantially proximate to one another and/or the central server, central controller, or remote host. In one example, the EGMs (or personal computing devices) and the central server, central controller, or remote host are located in a gaming establishment or a portion of a gaming establishment.
In other embodiments in which the gaming system includes: (a) an EGM (or personal computing device) configured to communicate with a central server, central controller, or remote host through a data network; and/or (b) a plurality of EGMs (or personal computing devices) configured to communicate with one another through a data network, the data network is a wide area network (WAN) in which one or more of the EGMs (or personal computing devices) are not necessarily located substantially proximate to another one of the EGMs (or personal computing devices) and/or the central server, central controller, or remote host. For example, one or more of the EGMs (or personal computing devices) are located: (a) in an area of a gaming establishment different from an area of the gaming establishment in which the central server, central controller, or remote host is located; or (b) in a gaming establishment different from the gaming establishment in which the central server, central controller, or remote host is located. In another example, the central server, central controller, or remote host is not located within a gaming establishment in which the EGMs (or personal computing devices) are located. In certain embodiments in which the data network is a WAN, the gaming system includes a central server, central controller, or remote host and an EGM (or personal computing device) each located in a different gaming establishment in a same geographic area, such as a same city or a same state. Gaming systems in which the data network is a WAN are substantially identical to gaming systems in which the data network is a LAN, though the quantity of EGMs (or personal computing devices) in such gaming systems may vary relative to one another.
In further embodiments in which the gaming system includes: (a) an EGM (or personal computing device) configured to communicate with a central server, central controller, or remote host through a data network; and/or (b) a plurality of EGMs (or personal computing devices) configured to communicate with one another through a data network, the data network is an internet (such as the Internet) or an intranet. In certain such embodiments, an Internet browser of the EGM (or personal computing device) is usable to access an Internet game page from any location where an Internet connection is available. In one such embodiment, after the EGM (or personal computing device) accesses the Internet game page, the central server, central controller, or remote host identifies a player prior to enabling that player to place any wagers on any plays of any wagering games. In one example, the central server, central controller, or remote host identifies the player by requiring a player account of the player to be logged into via an input of a unique username and password combination assigned to the player. The central server, central controller, or remote host may, however, identify the player in any other suitable manner, such as by validating a player tracking identification number associated with the player; by reading a player tracking card or other smart card inserted into a card reader (as described below); by validating a unique player identification number associated with the player by the central server, central controller, or remote host; or by identifying the EGM (or personal computing device), such as by identifying the MAC address or the IP address of the Internet facilitator. In various embodiments, once the central server, central controller, or remote host identifies the player, the central server, central controller, or remote host enables placement of one or more wagers on one or more plays of one or more primary or base games and/or one or more secondary or bonus games, and displays those plays via the Internet browser of the EGM (or personal computing device). Examples of implementations of Internet-based gaming are further described in U.S. Pat. No. 8,764,566, entitled “Internet Remote Game Server,” and U.S. Pat. No. 8,147,334, entitled “Universal Game Server,” which are incorporated herein by reference.
The central server, central controller, or remote host and the EGM (or personal computing device) are configured to connect to the data network or remote communications link in any suitable manner. In various embodiments, such a connection is accomplished via: a conventional phone line or other data transmission line, a digital subscriber line (DSL), a T-1 line, a coaxial cable, a fiber optic cable, a wireless or wired routing device, a mobile communications network connection (such as a cellular network or mobile Internet network), or any other suitable medium. The expansion in the quantity of computing devices and the quantity and speed of Internet connections in recent years increases opportunities for players to use a variety of EGMs (or personal computing devices) to play games from an ever-increasing quantity of remote sites. Additionally, the enhanced bandwidth of digital wireless communications may render such technology suitable for some or all communications, particularly if such communications are encrypted. Higher data transmission speeds may be useful for enhancing the sophistication and response of the display and interaction with players.
In these embodiments, the EGM 1000 includes a master gaming controller 1012 configured to communicate with and to operate with a plurality of peripheral devices 1022.
The master gaming controller 1012 includes at least one processor 1010. The at least one processor 1010 is any suitable processing device or set of processing devices, such as a microprocessor, a microcontroller-based platform, a suitable integrated circuit, or one or more application-specific integrated circuits (ASICs), configured to execute software enabling various configuration and reconfiguration tasks, such as: (1) communicating with a remote source (such as a server that stores authentication information or game information) via a communication interface 1006 of the master gaming controller 1012; (2) converting signals read by an interface to a format corresponding to that used by software or memory of the EGM; (3) accessing memory to configure or reconfigure game parameters in the memory according to indicia read from the EGM; (4) communicating with interfaces and the peripheral devices 1022 (such as input/output devices); and/or (5) controlling the peripheral devices 1022.

As generally described above, in certain embodiments, such as the example EGMs 2000a and 2000b illustrated in
In certain embodiments, the EGM is a device that has obtained approval from a regulatory gaming commission, and in other embodiments, the EGM is a device that has not obtained approval from a regulatory gaming commission.
The EGMs described above are merely three examples of different types of EGMs. Certain of these example EGMs may include one or more elements that may not be included in all gaming systems, and these example EGMs may not include one or more elements that are included in other gaming systems. For example, certain EGMs include a coin acceptor while others do not.
In various embodiments, an EGM may be implemented in one of a variety of different configurations. In various embodiments, the EGM may be implemented as one of: (a) a dedicated EGM in which computerized game programs executable by the EGM for controlling any primary or base games (referred to herein as “primary games”) and/or any secondary or bonus games or other functions (referred to herein as “secondary games”) displayed by the EGM are provided with the EGM prior to delivery to a gaming establishment or prior to being provided to a player; and (b) a changeable EGM in which computerized game programs executable by the EGM for controlling any primary games and/or secondary games displayed by the EGM are downloadable or otherwise transferred to the EGM through a data network or remote communication link; from a USB drive, flash memory card, or other suitable memory device; or in any other suitable manner after the EGM is physically located in a gaming establishment or after the EGM is provided to a player.
As generally explained above, in various embodiments in which the gaming system includes a central server, central controller, or remote host and a changeable EGM, the at least one memory device of the central server, central controller, or remote host stores different game programs and instructions executable by the at least one processor of the changeable EGM to control one or more primary games and/or secondary games displayed by the changeable EGM. More specifically, each such executable game program represents a different game or a different type of game that the at least one changeable EGM is configured to operate. In one example, certain of the game programs are executable by the changeable EGM to operate games having the same or substantially the same game play but different paytables. In different embodiments, each executable game program is associated with a primary game, a secondary game, or both. In certain embodiments, an executable game program is executable by the at least one processor of the at least one changeable EGM as a secondary game to be played simultaneously with a play of a primary game (which may be downloaded to or otherwise stored on the at least one changeable EGM), or vice versa.
In operation of such embodiments, the central server, central controller, or remote host is configured to communicate one or more of the stored executable game programs to the at least one processor of the changeable EGM. In different embodiments, a stored executable game program is communicated or delivered to the at least one processor of the changeable EGM by: (a) embedding the executable game program in a device or a component (such as a microchip to be inserted into the changeable EGM); (b) writing the executable game program onto a disc or other media; or (c) uploading or streaming the executable game program over a data network (such as a dedicated data network). After the executable game program is communicated from the central server, central controller, or remote host to the changeable EGM, the at least one processor of the changeable EGM executes the executable game program to enable the primary game and/or the secondary game associated with that executable game program to be played using the display device(s) and/or the input device(s) of the changeable EGM. That is, when an executable game program is communicated to the at least one processor of the changeable EGM, the at least one processor of the changeable EGM changes the game or the type of game that may be played using the changeable EGM.
In certain embodiments, the gaming system randomly determines any game outcome(s) (such as a win outcome) and/or award(s) (such as a quantity of credits to award for the win outcome) for a play of a primary game and/or a play of a secondary game based on probability data. In certain such embodiments, this random determination is provided through utilization of an RNG, such as a true RNG or a pseudo RNG, or any other suitable randomization process. In one such embodiment, each game outcome or award is associated with a probability, and the gaming system generates the game outcome(s) and/or the award(s) to be provided based on the associated probabilities. In these embodiments, since the gaming system generates game outcomes and/or awards randomly or based on one or more probability calculations, there is no certainty that the gaming system will ever provide any specific game outcome and/or award.
In certain embodiments, the gaming system maintains one or more predetermined pools or sets of predetermined game outcomes and/or awards. In certain such embodiments, upon generation or receipt of a game outcome and/or award request, the gaming system independently selects one of the predetermined game outcomes and/or awards from the one or more pools or sets. The gaming system flags or marks the selected game outcome and/or award as used. Once a game outcome or an award is flagged as used, it is prevented from further selection from its respective pool or set; that is, the gaming system does not select that game outcome or award upon another game outcome and/or award request. The gaming system provides the selected game outcome and/or award. Examples of this type of award evaluation are described in U.S. Pat. No. 7,470,183, entitled “Finite Pool Gaming Method and Apparatus”; U.S. Pat. No. 7,563,163, entitled “Gaming Device Including Outcome Pools for Providing Game Outcomes”; U.S. Pat. No. 7,833,092, entitled “Method and System for Compensating for Player Choice in a Game of Chance”; U.S. Pat. No. 8,070,579, entitled “Bingo System with Downloadable Common Patterns”; and U.S. Pat. No. 8,398,472, entitled “Central Determination Poker Game,” which are incorporated herein by reference.
In certain embodiments, the gaming system determines a predetermined game outcome and/or award based on the results of a bingo, keno, or lottery game. In certain such embodiments, the gaming system utilizes one or more bingo, keno, or lottery games to determine the predetermined game outcome and/or award provided for a primary game and/or a secondary game. The gaming system is provided or associated with a bingo card. Each bingo card consists of a matrix or array of elements, wherein each element is designated with separate indicia. After a bingo card is provided, the gaming system randomly selects or draws a plurality of the elements. As each element is selected, a determination is made as to whether the selected element is present on the bingo card. If the selected element is present on the bingo card, that selected element on the provided bingo card is marked or flagged. This process of selecting elements and marking any selected elements on the provided bingo cards continues until one or more predetermined patterns are marked on one or more of the provided bingo cards. After one or more predetermined patterns are marked on one or more of the provided bingo cards, game outcome and/or award is determined based, at least in part, on the selected elements on the provided bingo cards. Examples of this type of award determination are described in U.S. Pat. No. 7,753,774, entitled “Using Multiple Bingo Cards to Represent Multiple Slot Paylines and Other Class III Game Options”; U.S. Pat. No. 7,731,581, entitled “Multi-Player Bingo Game with Multiple Alternative Outcome Displays”; U.S. Pat. No. 7,955,170, entitled “Providing Non-Bingo Outcomes for a Bingo Game”; U.S. Pat. No. 8,070,579, entitled “Bingo System with Downloadable Common Patterns”; and U.S. Pat. No. 8,500,538, entitled “Bingo Gaming System and Method for Providing Multiple Outcomes from Single Bingo Pattern,” which are incorporated herein by reference.
In certain embodiments in which the gaming system includes a central server, central controller, or remote host and an EGM, the EGM is configured to communicate with the central server, central controller, or remote host for monitoring purposes only. In such embodiments, the EGM determines the game outcome(s) and/or award(s) to be provided in any of the manners described above, and the central server, central controller, or remote host monitors the activities and events occurring on the EGM. In one such embodiment, the gaming system includes a real-time or online accounting and gaming information system configured to communicate with the central server, central controller, or remote host. In this embodiment, the accounting and gaming information system includes: (a) a player database configured to store player profiles, (b) a player tracking module configured to track players (as described below), and (c) a credit system configured to provide automated transactions. Examples of such accounting systems are described in U.S. Pat. No. 6,913,534, entitled “Gaming Machine Having a Lottery Game and Capability for Integration with Gaming Device Accounting System and Player Tracking System,” and U.S. Pat. No. 8,597,116, entitled “Virtual Player Tracking and Related Services,” which are incorporated herein by reference.
As noted above, in various embodiments, the gaming system includes one or more executable game programs executable by at least one processor of the gaming system to provide one or more primary games and one or more secondary games. The primary game(s) and the secondary game(s) may comprise any suitable games and/or wagering games, such as, but not limited to: electro-mechanical or video slot or spinning reel type games; video card games such as video draw poker, multi-hand video draw poker, other video poker games, video blackjack games, and video baccarat games; video keno games; video bingo games; and video selection games.
In certain embodiments in which the primary game is a slot or spinning reel type game, the gaming system includes one or more reels in either an electromechanical form with mechanical rotating reels or in a video form with simulated reels and movement thereof. Each reel displays a plurality of indicia or symbols, such as bells, hearts, fruits, numbers, letters, bars, or other images that typically correspond to a theme associated with the gaming system. In certain such embodiments, the gaming system includes one or more paylines associated with the reels. The example EGM 2000b shown in
In various embodiments, one or more of the paylines is horizontal, vertical, circular, diagonal, angled, or any suitable combination thereof. In other embodiments, each of one or more of the paylines is associated with a plurality of adjacent symbol display areas on a requisite number of adjacent reels. In one such embodiment, one or more paylines are formed between at least two symbol display areas that are adjacent to each other by either sharing a common side or sharing a common corner (i.e., such paylines are connected paylines). The gaming system enables a wager to be placed on one or more of such paylines to activate such paylines. In other embodiments in which one or more paylines are formed between at least two adjacent symbol display areas, the gaming system enables a wager to be placed on a plurality of symbol display areas, which activates those symbol display areas.
In various embodiments, the gaming system provides one or more awards after a spin of the reels when specified types and/or configurations of the indicia or symbols on the reels occur on an active payline or otherwise occur in a winning pattern, occur on the requisite number of adjacent reels, and/or occur in a scatter pay arrangement.
In certain embodiments, the gaming system employs a ways to win award determination. In these embodiments, any outcome to be provided is determined based on a number of associated symbols that are generated in active symbol display areas on the requisite number of adjacent reels (i.e., not on paylines passing through any displayed winning symbol combinations). If a winning symbol combination is generated on the reels, one award for that occurrence of the generated winning symbol combination is provided. Examples of ways to win award determinations are described in U.S. Pat. No. 8,012,011, entitled “Gaming Device and Method Having Independent Reels and Multiple Ways of Winning”; U.S. Pat. No. 8,241,104, entitled “Gaming Device and Method Having Designated Rules for Determining Ways To Win”; and U.S. Pat. No. 8,430,739, entitled “Gaming System and Method Having Wager Dependent Different Symbol Evaluations,” which are incorporated herein by reference.
In various embodiments, the gaming system includes a progressive award. Typically, a progressive award includes an initial amount and an additional amount funded through a portion of each wager placed to initiate a play of a primary game. When one or more triggering events occurs, the gaming system provides at least a portion of the progressive award. After the gaming system provides the progressive award, an amount of the progressive award is reset to the initial amount and a portion of each subsequent wager is allocated to the next progressive award. Examples of progressive gaming systems are described in U.S. Pat. No. 7,585,223, entitled “Server Based Gaming System Having Multiple Progressive Awards”; U.S. Pat. No. 7,651,392, entitled “Gaming Device System Having Partial Progressive Payout”; U.S. Pat. No. 7,666,093, entitled “Gaming Method and Device Involving Progressive Wagers”; U.S. Pat. No. 7,780,523, entitled “Server Based Gaming System Having Multiple Progressive Awards”; and U.S. Pat. No. 8,337,298, entitled “Gaming Device Having Multiple Different Types of Progressive Awards,” which are incorporated herein by reference
As generally noted above, in addition to providing winning credits or other awards for one or more plays of the primary game(s), in various embodiments the gaming system provides credits or other awards for one or more plays of one or more secondary games. The secondary game typically enables an award to be obtained addition to any award obtained through play of the primary game(s). The secondary game(s) typically produces a higher level of player excitement than the primary game(s) because the secondary game(s) provides a greater expectation of winning than the primary game(s) and is accompanied with more attractive or unusual features than the primary game(s). The secondary game(s) may be any type of suitable game, either similar to or completely different from the primary game.
In various embodiments, the gaming system automatically provides or initiates the secondary game upon the occurrence of a triggering event or the satisfaction of a qualifying condition. In other embodiments, the gaming system initiates the secondary game upon the occurrence of the triggering event or the satisfaction of the qualifying condition and upon receipt of an initiation input. In certain embodiments, the triggering event or qualifying condition is a selected outcome in the primary game(s) or a particular arrangement of one or more indicia on a display device for a play of the primary game(s), such as a “BONUS” symbol appearing on three adjacent reels along a payline following a spin of the reels for a play of the primary game. In other embodiments, the triggering event or qualifying condition occurs based on a certain amount of game play (such as number of games, number of credits, amount of time) being exceeded, or based on a specified number of points being earned during game play. Any suitable triggering event or qualifying condition or any suitable combination of a plurality of different triggering events or qualifying conditions may be employed.
In other embodiments, at least one processor of the gaming system randomly determines when to provide one or more plays of one or more secondary games. In one such embodiment, no apparent reason is provided for providing the secondary game. In this embodiment, qualifying for a secondary game is not triggered by the occurrence of an event in any primary game or based specifically on any of the plays of any primary game. That is, qualification is provided without any explanation or, alternatively, with a simple explanation. In another such embodiment, the gaming system determines qualification for a secondary game at least partially based on a game triggered or symbol triggered event, such as at least partially based on play of a primary game.
In various embodiments, after qualification for a secondary game has been determined, the secondary game participation may be enhanced through continued play on the primary game. Thus, in certain embodiments, for each secondary game qualifying event, such as a secondary game symbol, that is obtained, a given number of secondary game wagering points or credits is accumulated in a “secondary game meter” configured to accrue the secondary game wagering credits or entries toward eventual participation in the secondary game. In one such embodiment, the occurrence of multiple such secondary game qualifying events in the primary game results in an arithmetic or exponential increase in the number of secondary game wagering credits awarded. In another such embodiment, any extra secondary game wagering credits may be redeemed during the secondary game to extend play of the secondary game.
In certain embodiments, no separate entry fee or buy-in for the secondary game is required. That is, entry into the secondary game cannot be purchased; rather, in these embodiments entry must be won or earned through play of the primary game, thereby encouraging play of the primary game. In other embodiments, qualification for the secondary game is accomplished through a simple “buy-in.” For example, qualification through other specified activities is unsuccessful, payment of a fee or placement of an additional wager “buys-in” to the secondary game. In certain embodiments, a separate side wager must be placed on the secondary game or a wager of a designated amount must be placed on the primary game to enable qualification for the secondary game. In these embodiments, the secondary game triggering event must occur and the side wager (or designated primary game wager amount) must have been placed for the secondary game to trigger.
In various embodiments in which the gaming system includes a plurality of EGMs, the EGMs are configured to communicate with one another to provide a group gaming environment. In certain such embodiments, the EGMs enable players of those EGMs to work in conjunction with one another, such as by enabling the players to play together as a team or group, to win one or more awards. In other such embodiments, the EGMs enable players of those EGMs to compete against one another for one or more awards. In one such embodiment, the EGMs enable the players of those EGMs to participate in one or more gaming tournaments for one or more awards. Examples of group gaming systems are described in U.S. Pat. No. 8,070,583, entitled “Server Based Gaming System and Method for Selectively Providing One or More Different Tournaments”; U.S. Pat. No. 8,500,548, entitled “Gaming System and Method for Providing Team Progressive Awards”; and U.S. Pat. No. 8,562,423, entitled “Method and Apparatus for Rewarding Multiple Game Players for a Single Win,” which are incorporated herein by reference.
In various embodiments, the gaming system includes one or more player tracking systems. Such player tracking systems enable operators of the gaming system (such as casinos or other gaming establishments) to recognize the value of customer loyalty by identifying frequent customers and rewarding them for their patronage. Such a player tracking system is configured to track a player's gaming activity. In one such embodiment, the player tracking system does so through the use of player tracking cards. In this embodiment, a player is issued a player identification card that has an encoded player identification number that uniquely identifies the player. When the player's playing tracking card is inserted into a card reader of the gaming system to begin a gaming session, the card reader reads the player identification number off the player tracking card to identify the player. The gaming system timely tracks any suitable information or data relating to the identified player's gaming session. The gaming system also timely tracks when the player tracking card is removed to conclude play for that gaming session. In another embodiment, rather than requiring insertion of a player tracking card into the card reader, the gaming system utilizes one or more portable devices, such as a mobile phone, a radio frequency identification tag, or any other suitable wireless device, to track when a gaming session begins and ends. In another embodiment, the gaming system utilizes any suitable biometric technology or ticket technology to track when a gaming session begins and ends.
In such embodiments, during one or more gaming sessions, the gaming system tracks any suitable information or data, such as any amounts wagered, average wager amounts, and/or the time at which these wagers are placed. In different embodiments, for one or more players, the player tracking system includes the player's account number, the player's card number, the player's first name, the player's surname, the player's preferred name, the player's player tracking ranking, any promotion status associated with the player's player tracking card, the player's address, the player's birthday, the player's anniversary, the player's recent gaming sessions, or any other suitable data. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed on a player tracking display. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed via one or more service windows that are displayed on the central display device and/or the upper display device. Examples of player tracking systems are described in U.S. Pat. No. 6,722,985, entitled “Universal Player Tracking System”; U.S. Pat. No. 6,908,387, entitled “Player Tracking Communication Mechanisms in a Gaming Machine”; U.S. Pat. No. 7,311,605, entitled “Player Tracking Assembly for Complete Patron Tracking for Both Gaming and Non-Gaming Casino Activity”; U.S. Pat. No. 7,611,411, entitled “Player Tracking Instruments Having Multiple Communication Modes”; U.S. Pat. No. 7,617,151, entitled “Alternative Player Tracking Techniques”; and U.S. Pat. No. 8,057,298, entitled “Virtual Player Tracking and Related Services,” which are incorporated herein by reference.
Certain of the gaming systems described herein, such as EGMs located in a casino or another gaming establishment, include certain components and/or are configured to operate in certain manners that differentiate these systems from general purpose computing devices, i.e., certain personal gaming devices such as desktop computers and laptop computers.
For instance, EGMs are highly regulated to ensure fairness and, in many cases, EGMs are configured to award monetary awards up to multiple millions of dollars. To satisfy security and regulatory requirements in a gaming environment, hardware and/or software architectures are implemented in EGMs that differ significantly from those of general purpose computing devices. For purposes of illustration, a description of EGMs relative to general purpose computing devices and some examples of these additional (or different) hardware and/or software architectures found in EGMs are described below.
At first glance, one might think that adapting general purpose computing device technologies to the gaming industry and EGMs would be a simple proposition because both general purpose computing devices and EGMs employ processors that control a variety of devices. However, due to at least: (1) the regulatory requirements placed on EGMs, (2) the harsh environment in which EGMs operate, (3) security requirements, and (4) fault tolerance requirements, adapting general purpose computing device technologies to EGMs can be quite difficult. Further, techniques and methods for solving a problem in the general purpose computing device industry, such as device compatibility and connectivity issues, might not be adequate in the gaming industry. For instance, a fault or a weakness tolerated in a general purpose computing device, such as security holes in software or frequent crashes, is not tolerated in an EGM because in an EGM these faults can lead to a direct loss of funds from the EGM, such as stolen cash or loss of revenue when the EGM is not operating properly or when the random outcome determination is manipulated.
Certain differences between general purpose computing devices and EGMs are described below. A first difference between EGMs and general purpose computing devices is that EGMs are state-based systems. A state-based system stores and maintains its current state in a non-volatile memory such that, in the event of a power failure or other malfunction, the state-based system can return to that state when the power is restored or the malfunction is remedied. For instance, for a state-based EGM, if the EGM displays an award for a game of chance but the power to the EGM fails before the EGM provides the award to the player, the EGM stores the pre-power failure state in a non-volatile memory, returns to that state upon restoration of power, and provides the award to the player. This requirement affects the software and hardware design on EGMs. General purpose computing devices are not state-based machines, and a majority of data is usually lost when a malfunction occurs on a general purpose computing device.
A second difference between EGMs and general purpose computing devices is that, for regulatory purposes, the software on the EGM utilized to operate the EGM has been designed to be static and monolithic to prevent cheating by the operator of the EGM. For instance, one solution that has been employed in the gaming industry to prevent cheating and to satisfy regulatory requirements has been to manufacture an EGM that can use a proprietary processor running instructions to provide the game of chance from an EPROM or other form of non-volatile memory. The coding instructions on the EPROM are static (non-changeable) and must be approved by a gaming regulators in a particular jurisdiction and installed in the presence of a person representing the gaming jurisdiction. Any changes to any part of the software required to generate the game of chance, such as adding a new device driver used to operate a device during generation of the game of chance, can require burning a new EPROM approved by the gaming jurisdiction and reinstalling the new EPROM on the EGM in the presence of a gaming regulator. Regardless of whether the EPROM solution is used, to gain approval in most gaming jurisdictions, an EGM must demonstrate sufficient safeguards that prevent an operator or a player of an EGM from manipulating the EGM's hardware and software in a manner that gives him an unfair, and in some cases illegal, advantage.
A third difference between EGMs and general purpose computing devices is authentication—EGMs storing code are configured to authenticate the code to determine if the code is unaltered before executing the code. If the code has been altered, the EGM prevents the code from being executed. The code authentication requirements in the gaming industry affect both hardware and software designs on EGMs. Certain EGMs use hash functions to authenticate code. For instance, one EGM stores game program code, a hash function, and an authentication hash (which may be encrypted). Before executing the game program code, the EGM hashes the game program code using the hash function to obtain a result hash and compares the result hash to the authentication hash. If the result hash matches the authentication hash, the EGM determines that the game program code is valid and executes the game program code. If the result hash does not match the authentication hash, the EGM determines that the game program code has been altered (i.e., may have been tampered with) and prevents execution of the game program code. Examples of EGM code authentication are described in U.S. Pat. No. 6,962,530, entitled “Authentication in a Secure Computerized Gaming System”; U.S. Pat. No. 7,043,641, entitled “Encryption in a Secure Computerized Gaming System”; U.S. Pat. No. 7,201,662, entitled “Method and Apparatus for Software Authentication”; and U.S. Pat. No. 8,627,097, entitled “System and Method Enabling Parallel Processing of Hash Functions Using Authentication Checkpoint Hashes,” which are incorporated herein by reference.
A fourth difference between EGMs and general purpose computing devices is that EGMs have unique peripheral device requirements that differ from those of a general purpose computing device, such as peripheral device security requirements not usually addressed by general purpose computing devices. For instance, monetary devices, such as coin dispensers, bill validators, and ticket printers and computing devices that are used to govern the input and output of cash or other items having monetary value (such as tickets) to and from an EGM have security requirements that are not typically addressed in general purpose computing devices. Therefore, many general purpose computing device techniques and methods developed to facilitate device connectivity and device compatibility do not address the emphasis placed on security in the gaming industry.
To address some of the issues described above, a number of hardware/software components and architectures are utilized in EGMs that are not typically found in general purpose computing devices. These hardware/software components and architectures, as described below in more detail, include but are not limited to watchdog timers, voltage monitoring systems, state-based software architecture and supporting hardware, specialized communication interfaces, security monitoring, and trusted memory.
Certain EGMs use a watchdog timer to provide a software failure detection mechanism. In a normally-operating EGM, the operating software periodically accesses control registers in the watchdog timer subsystem to “re-trigger” the watchdog. Should the operating software fail to access the control registers within a preset timeframe, the watchdog timer will timeout and generate a system reset. Typical watchdog timer circuits include a loadable timeout counter register to enable the operating software to set the timeout interval within a certain range of time. A differentiating feature of some circuits is that the operating software cannot completely disable the function of the watchdog timer. In other words, the watchdog timer always functions from the time power is applied to the board.
Certain EGMs use several power supply voltages to operate portions of the computer circuitry. These can be generated in a central power supply or locally on the computer board. If any of these voltages falls out of the tolerance limits of the circuitry they power, unpredictable operation of the EGM may result. Though most modern general purpose computing devices include voltage monitoring circuitry, these types of circuits only report voltage status to the operating software. Out of tolerance voltages can cause software malfunction, creating a potential uncontrolled condition in the general purpose computing device. Certain EGMs have power supplies with relatively tighter voltage margins than that required by the operating circuitry. In addition, the voltage monitoring circuitry implemented in certain EGMs typically has two thresholds of control. The first threshold generates a software event that can be detected by the operating software and an error condition then generated. This threshold is triggered when a power supply voltage falls out of the tolerance range of the power supply, but is still within the operating range of the circuitry. The second threshold is set when a power supply voltage falls out of the operating tolerance of the circuitry. In this case, the circuitry generates a reset, halting operation of the EGM.
As described above, certain EGMs are state-based machines. Different functions of the game provided by the EGM (e.g., bet, play, result, points in the graphical presentation, etc.) may be defined as a state. When the EGM moves a game from one state to another, the EGM stores critical data regarding the game software in a custom non-volatile memory subsystem. This ensures that the player's wager and credits are preserved and to minimize potential disputes in the event of a malfunction on the EGM. In general, the EGM does not advance from a first state to a second state until critical information that enables the first state to be reconstructed has been stored. This feature enables the EGM to recover operation to the current state of play in the event of a malfunction, loss of power, etc. that occurred just prior to the malfunction. In at least one embodiment, the EGM is configured to store such critical information using atomic transactions.
Generally, an atomic operation in computer science refers to a set of operations that can be combined so that they appear to the rest of the system to be a single operation with only two possible outcomes: success or failure. As related to data storage, an atomic transaction may be characterized as series of database operations which either all occur, or all do not occur. A guarantee of atomicity prevents updates to the database occurring only partially, which can result in data corruption.
To ensure the success of atomic transactions relating to critical information to be stored in the EGM memory before a failure event (e.g., malfunction, loss of power, etc.), memory that includes one or more of the following criteria be used: direct memory access capability; data read/write capability which meets or exceeds minimum read/write access characteristics (such as at least 5.08 Mbytes/sec (Read) and/or at least 38.0 Mbytes/sec (Write)). Memory devices that meet or exceed the above criteria may be referred to as “fault-tolerant” memory devices.
Typically, battery-backed RAM devices may be configured to function as fault-tolerant devices according to the above criteria, whereas flash RAM and/or disk drive memory are typically not configurable to function as fault-tolerant devices according to the above criteria. Accordingly, battery-backed RAM devices are typically used to preserve EGM critical data, although other types of non-volatile memory devices may be employed. These memory devices are typically not used in typical general purpose computing devices.
Thus, in at least one embodiment, the EGM is configured to store critical information in fault-tolerant memory (e.g., battery-backed RAM devices) using atomic transactions. Further, in at least one embodiment, the fault-tolerant memory is able to successfully complete all desired atomic transactions (e.g., relating to the storage of EGM critical information) within a time period of 200 milliseconds or less. In at least one embodiment, the time period of 200 milliseconds represents a maximum amount of time for which sufficient power may be available to the various EGM components after a power outage event has occurred at the EGM.
As described previously, the EGM may not advance from a first state to a second state until critical information that enables the first state to be reconstructed has been atomically stored. After the state of the EGM is restored during the play of a game of chance, game play may resume and the game may be completed in a manner that is no different than if the malfunction had not occurred. Thus, for example, when a malfunction occurs during a game of chance, the EGM may be restored to a state in the game of chance just prior to when the malfunction occurred. The restored state may include metering information and graphical information that was displayed on the EGM in the state prior to the malfunction. For example, when the malfunction occurs during the play of a card game after the cards have been dealt, the EGM may be restored with the cards that were previously displayed as part of the card game. As another example, a bonus game may be triggered during the play of a game of chance in which a player is required to make a number of selections on a video display screen. When a malfunction has occurred after the player has made one or more selections, the EGM may be restored to a state that shows the graphical presentation just prior to the malfunction including an indication of selections that have already been made by the player. In general, the EGM may be restored to any state in a plurality of states that occur in the game of chance that occurs while the game of chance is played or to states that occur between the play of a game of chance.
Game history information regarding previous games played such as an amount wagered, the outcome of the game, and the like may also be stored in a non-volatile memory device. The information stored in the non-volatile memory may be detailed enough to reconstruct a portion of the graphical presentation that was previously presented on the EGM and the state of the EGM (e.g., credits) at the time the game of chance was played. The game history information may be utilized in the event of a dispute. For example, a player may decide that in a previous game of chance that they did not receive credit for an award that they believed they won. The game history information may be used to reconstruct the state of the EGM prior to, during, and/or after the disputed game to demonstrate whether the player was correct or not in her assertion. Examples of a state-based EGM, recovery from malfunctions, and game history are described in U.S. Pat. No. 6,804,763, entitled “High Performance Battery Backed RAM Interface”; U.S. Pat. No. 6,863,608, entitled “Frame Capture of Actual Game Play”; U.S. Pat. No. 7,111,141, entitled “Dynamic NV-RAM”; and U.S. Pat. No. 7,384,339, entitled, “Frame Capture of Actual Game Play,” which are incorporated herein by reference.
Another feature of EGMs is that they often include unique interfaces, including serial interfaces, to connect to specific subsystems internal and external to the EGM. The serial devices may have electrical interface requirements that differ from the “standard” EIA serial interfaces provided by general purpose computing devices. These interfaces may include, for example, Fiber Optic Serial, optically coupled serial interfaces, current loop style serial interfaces, etc. In addition, to conserve serial interfaces internally in the EGM, serial devices may be connected in a shared, daisy-chain fashion in which multiple peripheral devices are connected to a single serial channel.
The serial interfaces may be used to transmit information using communication protocols that are unique to the gaming industry. For example, IGT's Netplex is a proprietary communication protocol used for serial communication between EGMs. As another example, SAS is a communication protocol used to transmit information, such as metering information, from an EGM to a remote device. Often SAS is used in conjunction with a player tracking system.
Certain EGMs may alternatively be treated as peripheral devices to a casino communication controller and connected in a shared daisy chain fashion to a single serial interface. In both cases, the peripheral devices are assigned device addresses. If so, the serial controller circuitry must implement a method to generate or detect unique device addresses. General purpose computing device serial ports are not able to do this.
Security monitoring circuits detect intrusion into an EGM by monitoring security switches attached to access doors in the EGM cabinet. Access violations result in suspension of game play and can trigger additional security operations to preserve the current state of game play. These circuits also function when power is off by use of a battery backup. In power-off operation, these circuits continue to monitor the access doors of the EGM. When power is restored, the EGM can determine whether any security violations occurred while power was off, e.g., via software for reading status registers. This can trigger event log entries and further data authentication operations by the EGM software.
Trusted memory devices and/or trusted memory sources are included in an EGM to ensure the authenticity of the software that may be stored on less secure memory subsystems, such as mass storage devices. Trusted memory devices and controlling circuitry are typically designed to not enable modification of the code and data stored in the memory device while the memory device is installed in the EGM. The code and data stored in these devices may include authentication algorithms, random number generators, authentication keys, operating system kernels, etc. The purpose of these trusted memory devices is to provide gaming regulatory authorities a root trusted authority within the computing environment of the EGM that can be tracked and verified as original. This may be accomplished via removal of the trusted memory device from the EGM computer and verification of the secure memory device contents is a separate third party verification device. Once the trusted memory device is verified as authentic, and based on the approval of the verification algorithms included in the trusted device, the EGM is enabled to verify the authenticity of additional code and data that may be located in the gaming computer assembly, such as code and data stored on hard disk drives. Examples of trusted memory devices are described in U.S. Pat. No. 6,685,567, entitled “Process Verification,” which is incorporated herein by reference.
In at least one embodiment, at least a portion of the trusted memory devices/sources may correspond to memory that cannot easily be altered (e.g., “unalterable memory”) such as EPROMS, PROMS, Bios, Extended Bios, and/or other memory sources that are able to be configured, verified, and/or authenticated (e.g., for authenticity) in a secure and controlled manner.
According to one embodiment, when a trusted information source is in communication with a remote device via a network, the remote device may employ a verification scheme to verify the identity of the trusted information source. For example, the trusted information source and the remote device may exchange information using public and private encryption keys to verify each other's identities. In another embodiment, the remote device and the trusted information source may engage in methods using zero knowledge proofs to authenticate each of their respective identities.
EGMs storing trusted information may utilize apparatuses or methods to detect and prevent tampering. For instance, trusted information stored in a trusted memory device may be encrypted to prevent its misuse. In addition, the trusted memory device may be secured behind a locked door. Further, one or more sensors may be coupled to the memory device to detect tampering with the memory device and provide some record of the tampering. In yet another example, the memory device storing trusted information might be designed to detect tampering attempts and clear or erase itself when an attempt at tampering has been detected. Examples of trusted memory devices/sources are described in U.S. Pat. No. 7,515,718, entitled “Secured Virtual Network in a Gaming Environment,” which is incorporated herein by reference.
Mass storage devices used in a general purpose computing devices typically enable code and data to be read from and written to the mass storage device. In a gaming environment, modification of the gaming code stored on a mass storage device is strictly controlled and would only be enabled under specific maintenance type events with electronic and physical enablers required. Though this level of security could be provided by software, EGMs that include mass storage devices include hardware level mass storage data protection circuitry that operates at the circuit level to monitor attempts to modify data on the mass storage device and will generate both software and hardware error triggers should a data modification be attempted without the proper electronic and physical enablers being present. Examples of using a mass storage device are described in U.S. Pat. No. 6,149,522, entitled “Method of Authenticating Game Data Sets in an Electronic Casino Gaming System,” which is incorporated herein by reference.
Various changes and modifications to the present embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
This application is a continuation of, claims priority to and the benefit of U.S. patent application Ser. No. 14/862,914, filed on Sep. 23, 2015, the entire content of which is incorporated by reference herein.
