Patent Application
20150018081
The recent proliferation of casino gambling institutions in non-traditional locations such as Native-American reservations, riverboats, and cruise ships has placed significant competitive pressure on casinos in more traditional locations such as Las Vegas and Atlantic City to attract and retain customers. Moreover, in most traditional gambling locales, there exist a substantial number of casinos which compete head-to-head for the same group of gamblers. For example, the Las Vegas strip alone has over thirty casinos in direct competition with one another. Thus, the competition to draw players into a particular casino and have them return again has become an extremely difficult task for casino owners.
Increasingly, casinos are offering incentives in an effort to attract customers and retain them over time. For example, progressive slot machines featuring relatively large progressive jackpots have been employed to entice players into casinos. However, these machines pay out infrequently and are becoming commonplace. Consequently, they are becoming less attractive to many players. Moreover, since progressive jackpots are found in most casinos, they do not encourage players to choose one casino over another.
Casinos have also formed player slot clubs as a method of attracting and retaining customers. Such slot clubs operate to enroll players and allow them to earn reward points for gambling activity. Reward points may be exchanged for lodging, food or other services offered at a casino. Often, however, a player may join several slot clubs and become associated with a number of casinos. Consequently, for some players, the incentive to visit a particular casino no longer exists, rendering the present casino slot club format ineffective for its intended purpose.
In looking for new ways to attract and retain customers, casinos have sought to improve the experience of slot machine play by implementing systems for creating a group play format, so as to attract greater numbers of customers into a casino. For example, U.S. Pat. No. 5,564,700 to Celona describes a system for splitting a progressive jackpot amongst multiple players of linked gaming machines when a player at one machine hits the progressive winning combination. By splitting the jackpot amongst the players, the system creates the semblance of group play, thereby enhancing the gambling experience for some players. However, aside from the fact that the players are linked by a group of machines, the group aspect of the game is quite passive, and does not increase a player's loyalty to a particular casino.
U.S. Pat. No. 5,766,076 to Pease et al. describes a progressive gaming system in which multiple casinos or other groupings are coupled to a central system, and the central system provides each casino or group with a predetermined number of chances at a prize for each buy-in, i.e., each multiple of a predetermined amount of contribution to the prize or jackpot. If a prize is awarded as a result of such a buy-in, the casino or group randomly splits the prize amongst the players who are actively playing in that casino or group. Thus, it is possible for a player to win a progressive jackpot even though that player is not present in the casino in which the winning gaming device is located. However, since the Pease et al. system is configured to select a winner at random, the players are unable to influence the outcome of a game or the distribution of the award amongst the members of the group.
Pease et al. also discloses a system for tracking the activity of a group of players to facilitate the random distribution of a prize. Player-tracking, as the name indicates, involves tracking individual player usage of gaming devices. In prior art player-tracking systems, the player is issued a player identification card which has encoded thereon a player identification number that uniquely identifies the player. The individual gaming devices are fitted with a card reader, into which the player inserts a player-tracking card prior to playing the associated game.
By tracking individual players, usage can be monitored, allowing gaming establishments to target individual players with direct marketing techniques such as bonuses or rewards. U.S. Pat. No. 5,752,882 to Acres et al. describes a prior art player-tracking system which facilitates communication between a network of gaming devices to provide a variety of promotional bonuses such as multiple jackpot bonuses, mystery jackpot bonuses, progressive jackpot bonuses, or player specific bonuses.
Consequently, despite recent attempts in the prior art to attract groups of players to casinos by creating a group playing environment, the systems presently in place do not enable the members of a group to influence or direct the distribution of a winning jackpot amongst the group members. Thus, the allure of such systems is relatively small.
The present invention is directed to a new and useful system and method for enhancing the experience of slot machine play by facilitating group play by members of a team associated with a casino slot club and by enabling the team to directly influence the distribution of a winning jackpot amongst its members. It would be desirable to both players and casinos to provide a system for facilitating group play which enables the group members to influence or direct the distribution of a winning jackpot amongst the group. Such a system would serve to bring greater numbers of players into a casino and retain their loyalty to the casino over time, thereby increasing the casino's profits.
In accordance with an exemplary embodiment of the present invention, the system for facilitating group play by a team of members associated with a casino slot club comprises a memory storage device and a processor. The memory storage device contains a player database including information relating to each team member, a team's database including information relating to each team, and a team plan database including information relating to a set of rules for allocating rewards to the members of the team when a payout is obtained by, or is due to, a particular team member.
The processor is adapted and configured to receive a player identifier corresponding to a team member and receive a signal indicating a payout to the team member. The processor is further adapted to retrieve information relating to the player from the player database, retrieve information from the teams database relating to the players team and retrieve information from the team plan database relating to the rules for rewarding the members of the player's team. In addition, the processor is configured to evaluate the set of rules, and distribute a reward to each team member in accordance with the set of rules.
Generally, in accordance with an exemplary embodiment of the present invention, a method is provided for facilitating group play by a team of members which comprises the steps of identifying the members of the team, identifying a set rules for rewarding the members of the team when a payout is due to a game-playing team member, detecting a payout due to a game-playing team member, and rewarding the members of the team in accordance with the set of rules.
The step of identifying a set of rules for rewarding members of the team includes identifying a set of rules in a team plan database designated by the team. The rules or team plan can include, among other things, a minimum payout threshold, one or more player eligibility requirements, a bonus activity multiplier, and a condition for effecting reward multiplication, such as player activity.
These and other features of the system and method disclosed herein will become more readily apparent from the following description of the drawings.
So that those having ordinary skill in the art to which the disclosed system and method pertains will more readily understand how to employ and use the same, reference may be made to the drawings wherein:

Player eligibility requirements may depend on frequency of play. For example, to be eligible to receive a reward or bonus, a team member must have played the particular casino he is registered with within a given time period (e.g., within the previous thirty days). Alternatively, the eligibility of a team member may depend upon the amount of a wager. For example, to be eligible to receive a reward or bonus a team member must have wagered a minimum amount of money during a given time period (e.g., ten thousand dollars wagered within the previous thirty day period). Those skilled in the art will readily appreciate that any number of different requirements can be designated by a team upon registration. If a player fails to meet an eligibility requirement set forth in a team plan, then that player would not share in a team reward or bonus. Player eligibility may be reinstated when the given requirements are met. It is envisioned that eligibility requirements can be selected from a set of predetermined rules or they can be custom designed by the team members. In either instance, it would be possible to revise the team plan should the casino or team members decide to change the eligibility requirements for the team.
A player's activity status in the team database relates to the amount of the bonus that may be distributed to the player when a payout is obtained by or is due to another game-playing team member. More particularly, player activity can be linked to the activity multiplier contained in field 164 (discussed below with reference to
Referring now to
The team plan identifier in field 161 designates specific plans which may be selected by the members of a team. As discussed herein, a team plan can be selected from a group of plans designed by the casino, or it can be customized by the team members themselves. The payout threshold in field 162 defines the payout amount that will trigger the distribution or allocation of a reward or bonus amongst the members of a team. For example, a team may chose to set the payout threshold at one thousand dollars. Thus, rewards or bonuses would be distributed in accordance with the team plan when one of the team members obtains a payout that exceeds one-thousand dollars. Alternatively, the team may decide that bonuses should be distributed when the payout is greater than or equal to the payout threshold.
The bonus amount stored in field 163 of team plan database 160 defines the amount of the bonus the team members will receive when a team member receives or is due a payout. The bonus amount can be a percentage of the jackpot of the winning team member (e.g., ten percent), or a fixed dollar amount (e.g., one hundred dollars). It is envisioned that team bonuses may be subtracted from a winning team members jackpot whereby the winning team member receives only the remainder of the payout, or team bonuses may be paid out by the casino such that the winning team member receives the entire jackpot. It is also envisioned that team bonuses can be non-monetary rewards such as lodging, food or other services offered at a casino.
The activity multiplier stored in field 164 of team plan database 160 defines the factor by which a bonus amount may be increased for a team member whose status is active at the time a payout is received by, or is due to, a winning team member. The activity multiplier, or multiplication factor may be a whole number or a fractional number. For example, as illustrated in
There may arise an instance wherein a team will decide that the distribution of bonuses amongst its members should not be determined, at least in part, by the play activity of its members, i.e., the fact that a team member is active at the time a reward is distributed should not serve to increase the amount of their bonus. In such a case, the activity multiplier in field 163 would be set to one. Thus, the reward distribution would be based solely upon eligibility requirements set forth in field 165 of team plan database 160.
The eligibility requirements set forth in field 165 of team plan database 160 define the rules for distributing or allocating bonuses to team members when a team member receives or is due a payout. As stated previously, eligibility requirements are variable and may be designated to depend upon the frequency of play or the amount wagered by a particular player during a given time period. For example, as illustrated in
Other requirements may include that a team member place a telephone call to the casino during a given time period to hear an advertisement concerning certain goods or services offered by the casino, or that the team member submit to the casino proof of purchase of certain goods or services offered by the casino or by others having a partnership arrangement with the casino, such as an airline or hotel chain.
Those skilled in the art will readily appreciate that a team may base bonus eligibility on one or more of a number of criteria or conditions associated with game play or with the casino. In accordance with the present invention, if a player fails to meet an eligibility requirement, they would not receive a reward or bonus when a team member receives or is due a payout which is equal to or in excess of the payout threshold designated in the team plan database. However, a player who is ineligible may alter their eligibility status and become eligible to receive a bonus once they have met the eligibility requirements set forth in the team plan.
By way of example, players 1 through 5 register a slot club team identified as “Z100” with a team plan “XYZ” that provides a payout threshold of one thousand dollars ($1000), a team bonus amount of ten percent (10%) for all eligible team members (i.e., those whose club membership has not lapsed), and an activity multiplier of two (2) which would yield a twenty percent (20%) net bonus to all active team members. The team plan further provides that team bonuses are to be paid out by the casino rather than subtracted from the jackpot of a winning team member.
Of the five team members, players 1, 2 and 3 join one another on a trip to the casino in which team “Z100” is registered. At such a time, player 4 is eligible to receive a team bonus, but player 5 whose club membership has lapsed, is not eligible for a bonus. During the course of their visit to the casino, player 1 hits a jackpot worth ten thousand dollars ($10,000). At the same time, player 2 is actively playing a gaming device, but player 3 is dining at a nearby restaurant and is thus not active. In accordance with team plan “XYZ”, player 1 collects the dollar amount of the jackpot ($10,000), player 2 who is eligible and active receives a team bonus equal to twenty percent of the jackpot ($2,000), player 3 who is eligible and not active receives a team bonus equal to ten percent of the jackpot ($1,000), player 4 who is also eligible and not active receives a team bonus equal to ten percent of the jackpot ($1,000) and player 5 who is ineligible does not receive a team bonus.

Advancement to step 514 includes retrieving the particular team record 50 associated with the identified team member from the teams database 150 contained in storage device 120 (see
At step 521 processor 110 retrieves the eligibility requirement stored in field 165 of the team plan database, based upon the team plan identifier in field 152 of the team record previously retrieved. Thereupon, at step 522 processor 110 determines whether the current activity of the subject player alters the player's eligibility status. For example, if the player is a member of a team utilizing team plan “FGH”, the present activity would render the player eligible for a bonus, since the eligibility requirement in field 165 for team plan “FGH” is at least one play session per year. However, if the player is a member of a team utilizing team plan “ABC”, the present activity would have no effect on the player's eligibility for a bonus, since the eligibility requirement is not based on activity. Rather, it is based upon whether the player has an outstanding hotel reservation. In the case of the processor determining that the current activity renders the player eligible for a reward, the processor advances to step 518 where the value in the player's eligibility status field 154 in the team record 50 is set to “ELIGIBLE”. In the case of the processor determining that the current activity does not render the player eligible for a reward, processor advances to step 519 where the value in field 143 of the player's record in player database 140 is updated to indicate the instant date as the “Date of Last Activity”.
Alternatively, if it is determined in step 517 that the player is already eligible to receive a reward because the player has previously met the eligibility requirement designated by the team, then the process advances directly to step 519 and the value in field 143 of the player's record in player database 140 is simply updated to indicate the instant date as the “Date of Last Activity”.
In the above example, if the subject player was a member of a team utilizing team plan “DEF”, and at step 517 it was determined that the player was ineligible for a bonus, step 522 would include the additional action of retrieving information from an appropriate field in player database 140 to determine whether the present amount wagered by the player has satisfied the eligibility requirement set forth in field 165. Moreover, the processor would determine whether the amount of the present wager caused the total amount wagered by the player during the current calendar year to exceed five hundred dollars. If the present wager did indeed satisfy the eligibility requirement, the player's eligibility status in field 154 would be altered appropriately.
Referring to
At step 613 the process includes receiving a signal from gaming machine 201 indicating that a player has obtained or is due a payout. Once the signal has been received, processor 110 will determine at step 614 whether the payout that has been obtained by or is due to the winning team member is greater than or equal to the payout threshold designated in field 162 of team plan database 160. If the payout received by or due to the winning team member is not greater than or equal to the payout threshold stored in field 162, then processor 110 will dispense the payout to the winning team member at step 604 in a conventional manner and loop back to step 611. However, if the payout obtained by or due to the winning team member is greater than or equal to the payout threshold stored in field 162, then processor 110 proceeds to step 615 wherein a determination is made as to whether any other team member is currently active or eligible.
In essence, step 615 commences a bonus distribution subroutine which includes the step 616 wherein processor 110 retrieves the team plan information from team plan database 160 based upon the team plan identifier associated with the member's team. Thereupon, in steps 617 and 618 the processor retrieves the “Bonus Amount” and the “Activity Multiplier”, respectively, from fields 163 and 164 in team plan database 160.
Once the bonus amount and activity multiplier have been retrieved from team plan database 160, processor 110 proceeds to step 619 wherein team member bonuses are determined based upon the information provided for each team member in the respective “Activity Status” and “Eligibility Status” fields 154 and 155 of team record 50 and the appropriate rules set forth in the team plan. In a preferred embodiment of the present invention, the rules comprise the payout threshold, the bonus amount and the activity multiplier. Upon determining the amount of the bonus to be distributed to each team member in accordance with the rules defined by the team and stored in the team plan database 160, step 620 enables processor 110 to update each player's total dollar volume earned to date from team membership in field 145 of player database 140 by adding the determined bonus award to the present value stored therein.
The reward determination process further includes the step 621 of updating the data stored in the “Team Bonus Owed To Player” field 146 of player database 140 for each team member receiving a bonus award. Once the player database has been updated, processor 110 advances to step 622 wherein the appropriate form of payout is determined. For example, if it is determined that the payout is to be dispensed to an active player, the processor will signal the gaming machine of the active player to dispense the bonus award in step 623. However, if the team member is not actively playing and the team plan provides for a particular method for paying out awards, i.e., by printing and mailing a reward voucher, the processor will effectuate an appropriate payout in step 623. In such an embodiment, a record in teams database 150 or team plan database 160 would include an appropriate field for storing data indicating the form of the payout. As with other elements of the team plan, the form of the payout may be designated by the members of the team or provided by the casino. Those skilled in the art will readily appreciate that once a player has received a team bonus in accordance with the team plan, either by having it dispensed from a gaming machine, delivered through the mail, transferred to an account, or similarly transmitted by some other well known method, the value of the team bonus owed to the player in field 146 of player database 140 would be set to zero.
Referring now to
Once the player's record has been retrieved, the process advances to step 716 wherein the date of the player's last activity is determined from field 143. At step 717 a determination is made as to whether the player is eligible to receive a reward based upon the player's data and the team's eligibility requirements set forth in field 165 of the team plan database 161. Player data constitutes any type of tracked information relating to a player that is necessary to determine player eligibility. For example, if eligibility depends upon whether a player has an outstanding hotel reservation, as in team plan “ABC”, then server 100 would access the hotel reservation system (not shown) in a conventional manner and determine, based upon a player identifier, whether a player does indeed have an outstanding hotel reservation. Player data may also constitute information such as the “Date of Last Activity” stored in field 143 of player database 140. As illustrated in
It is envisioned that the process for updating player eligibility may include a subsequent step in which processor 110 determines whether there is another player in the current team record who's eligibility status has not yet been updated. If the determination is affirmative, then processor 110 will return to step 714 and continue from that point. However, if the determination is negative, processor 110 will continue to step 719 which involves the retrieval of another team record from teams database 150 and then returning to step 714.
It will be readily appreciated by those skilled in the art that the process of updating player eligibility will be repeated for each team record 50 in the teams database 150. It is envisioned that the order of team record selection during the process would be conducted in a sequential manner based upon the alpha-numeric team identifier provided in each team record contained in teams database 150.
In one embodiment of the present invention, team members receive a password or identification code for accessing a website over the internet. The website would enable team members to monitor team activity remotely and see outcomes achieved by members of their team in real time. Thus, a team member can determine whether a bonus has been distributed without being present at the casino when another team member receives a payout from a gaming machine. In addition, the website can serve as a chat room to enable team members to communicate with one another. It is also envisioned that the act of logging on to the website could serve as a mechanism for altering eligibility status or activity status in fields 154 and 155 of a team database 50. Thus, in such a case it would unnecessary for a team member to physically gamble at a casino to remain active and eligible to receive bonuses.
In another embodiment of the present invention, a team must meet a targeted activity goal in order for the team members to become or remain eligible for rewards or bonuses. For example, at least one team member must have wagered at least one hundred dollars during a one-month period for the team as a whole to be eligible for bonuses. Alternatively, the team as a whole must have earned a predetermined number of points (which may correlate to gambling activity) during a given time period to become or remain eligible for team bonuses. In such instances, the server would periodically review and update a team record in the teams database 150 to reflect whether they have met their targeted activity goal.
In yet another embodiment of the present invention, eligibility for team rewards is based on actual past activity rather than meeting a targeted activity goal. For example, for every thousand dollars wagered by the team during a given time period, e.g., one year, the team would advance one level in a team reward system instituted by the casino. As the team attains higher levels within the system, the team members would be eligible to receive greater rewards. For example, as the team advances through levels of the system, team bonuses rewards would increase incrementally, e.g., in increments of five percent. Thus, at the first level in the system, team members may receive a five percent bonus when a team member receives a winning payout, while at the second level they would receive a ten percent bonus when a team member receives a winning payout. Preferably, the level attained by the team would be stored in the team's record contained in the teams database 150.
It is envisioned that the system and method of the present invention can be utilized by a casino to increase its share of new players as well as its profits. For example, a casino could target groups or clubs planning conventions. The casino would offer members of the group the opportunity to participate in the team gaming program as a way of enhancing the gambling experience and promoting team spirit. Promotional materials may be offered to the group explaining that the subject casino team play format enables players to effectively “hedge their bets,” since the success of one player brings success for the entire group. This would mitigate common fears about losing large sums of money.
The present invention also provides casinos with a means of generating revenues by offering customized team gear, such as matching tee-shirts or hats bearing a casino's logo and the team name or logo. Team gear can be purchased in a conventional manner or by redeeming bonus points accumulated by the team members. It is also envisioned that team gear could be offered at no expense upon registration.
As noted hereinabove, in accordance with the present invention, a team plan may be selected from a number of predetermined team plans designed by the casino. It is envisioned that a casino could design team plans aimed at different types of players. For example, one plan aimed at seasonal players would require the team members to play once every six months to remain eligible. The seasonal plan would provide a moderate bonus scheme. Another plan aimed at frequent players would require the team members to play at least twice a month, encouraging those who live within driving distance of a casino to play more often than those who do not. The frequent player plan would have a more attractive bonus scheme than the seasonal plan. In a third plan aimed at regular patrons of the casino, team members would be required to play at least two times a week. Such a plan would provide the most attractive bonus scheme available to the casino club members.
In an effort to encourage frequent team play, a casino may offer a plan in which team bonuses increase in proportion to an increase in the frequency of play or the volume of wagers. A casino may also employ the system of the present invention to increase play at certain times during the day by offering increased team bonus during certain hours of the day in which all of the team members are active when a payout is received by one of the team members.
In sum, a new and useful system and method are provided for facilitating group play by members of a team associated with a casino slot club. This novel and unique system and method serve to enhance the experience of slot machine play by enabling a team to directly influence or orchestrate the distribution of a winning jackpot amongst its members. In so doing, the present invention functions to attract greater numbers of players into a casino, thereby increasing the casino's profits. It also functions to retain players by instilling a sense of player loyalty to a particular casino and creating peer pressure amongst a group of players to actively participate in the slot club on a frequent basis.
It should be recognized that the way in which information is utilized and stored in the various databases described herein does not limit the scope of the subject matter of the present invention in any manner. Rather, the databases and the information stored therein are merely examples of the way in which information may be stored and utilized to enable one skilled in the art to practice the subject invention.
Although the system and method disclosed herein has been described with respect to preferred embodiments, it is apparent that modifications, changes and enhancements can be made thereto without departing from the spirit and scope of the invention as defined by the appended claims.
