The remaining account total information is received from the mobile wagering sub-system 102. The cashier pays the player the amount due and confirms the payment at the POS. The client device is then available for use by another player.
The method then proceeds to block 720 where mobile wagering sub-system 102 is configured to communicate with the video presentation sub-system 104. At block 720, the video presentation subsystem 104 receives game play information and integrates it with other data sources as described above. The video presentation sub-system 104 generates a video presentation that is broadcast via a private network to participating gaming venues. As described above a stationary monitor 110 is communicatively coupled to the video presentation sub-system 104 via the video presentation client 116. The stationary monitor client is configured to receive and present the game session output generated by the video presentation sub-system. In one illustrative embodiment, the video content is designed to provide enhanced content to the players and to increase the interaction between the players and the games. Additionally, the video content adds interest and excitement to the games. In addition to game-specific content, such as broadcasting a live tournament, the system can be used for a multitude of purposes, including, but not limited to, announcements and pictures on winners, informational videos about sponsoring charities, announcements of new games and upcoming events, advertising, etc.

The illustrative screenshot 802 also includes a “Help” button 806 which is used to alert the illustrative cashier interacting with the POS device 114 that some assistance is required.
Additionally, the screenshot 802 includes a “Cash Out” button 808, which may initiate a redemption transaction at the POS device 114. A “Cash Out” input is received by the authorized mobile device when a player desires to conclude interacting with the authorized mobile device 112. Alternatively, the illustrative player may go directly to the cashier that interacts with the POS device and player can directly request a “cash-out” from the cashier. The illustrative cashier then proceeds to interact with the POS device (or POS app) by selecting the authorized mobile device 112 that is associated with player. After the POS device receives a cash-out input corresponding to the player's authorized mobile device 112, a cash-out request message is communicated to the appropriate distributor server 304. In the illustrative embodiment, the distributor server 304 communicates to the POS device the session balance 810 that is presented on the authorized mobile device. The POS device 114 is configured to receive a POS device cash-out input that confirms the actual amount or credits or funds indicated on the authorized mobile device 114. The POS device cash-out input is then communicated to the appropriate distribution server 304, which then proceeds to communicate that all player interactions with the authorized mobile device have been terminated; and the authorized mobile device displays a player account session balance of $0.00.
The player account balance output 810 is presented as a “cash” balance; however, “cash” is not stored on the authorized mobile device. The “cash” balance presented in the player account session balance output 808 represents credit or monetary value that is available for wagering, depending on jurisdictional requirements. If required, the credits may then be converted to fungible cash or other type of financial proceeds, e.g. chips or tickets, when the player cashes out.
The illustrative screenshot 802 also includes a jackpot value 812, which may correspond to a progressive prize. Progressive prizes are prizes that grow in real time as a function of game play. Some progressive prizes may accumulate prizes within a venue. More generally, progressive prizes accumulate prizes from multiple play locations.
An “Add Cash” button 814 provides an input that triggers a communication to the illustrative POS device 114, which notifies the illustrative cashier that the player accessing the authorized mobile device 112 wants to add credits or funds to the to the authorized mobile device for game play. The process of adding credits or funds to the authorized mobile device is described above.
By way of example and not of limitation, the types of games supported by the centralized gaming system 100 includes include electronic pull-tab games, bingo, electronic high-speed bingo, electronic high-speed bingo tournaments and other such games of chance.
Electronic pull-tab games are finite pool games that comply with jurisdictional rules limiting prize values and restricting types of permissible video animation. Typically, electronic pull-tab games have small finite-pool sizes, low wager denominations and low prize values compared to casino slot machines. Each game/denomination combination is associated with a different pull-tab deck. Electronic pull-tab games include at least one deck that is always open for each available game. Additionally, electronic pull-tab games include a deck serial number which is displayed on the client game screen as well as in an illustrative Game Information Screens. Typical pull-tab games are available in $0.25, $0.50, $1, $2, and $5 denominations. Available denominations and prize limits are generally controlled by jurisdictional regulations. Operators are able to select which games and denominations are active for each venue and to be able to close any deck.

The player inputs shown in the
More specifically, the “Add Cash” control button 902 is associated with a player input that allows the player to signal to the POS device 114 that the player wants to add more cash to the player account session. The “Menu” control button 602 allows the player to return to the game selection menu screen. The “Game Info” control button 906 provides access to screens which define prizes and rules of play. The “Denomination” amount control button 908 displays the current denomination and repeated presses of the Denomination amount control button may change the displayed denomination and cause the game to switch to a different finite pool. The “Cash” credit counter 910 displays the available cash credit balance that is available for game play. The “Win” credit counter 912 displays the amount won in the prior game session. For the illustrative pull-tab game, the “Play” control button 914 initiates a game session.

As stated throughout, the mobile wagering sub-system 102 determines the outcome that is presented in the fully-revealed state presented in screen shot 922.
The pull-tab games presented herein include an auto-close option that may be selected by the operator, for any game played at a particular venue. The auto-close option automatically replaces a finite game pool with a new pool when all prizes exceeding a predetermined value for the deck have been exhausted and the game may no longer be desirable by players. When the auto-close option is turned “ON,” a deck may automatically close and be replaced by a new deck when prizes over a game specific value set in the portal are gone. For example, a game may have 3 large value prizes and when the last prize is awarded, the deck may close and a new deck may open. By way of example and not of limitation, the auto close option is identified in the client game information when it is active, so players may know that it is active. A notification may also be given to all active clients when a new deck is open. This feature is attractive to players because they are always assured that there are always some valuable prizes remaining in a deck they may be playing.
There are a variety of other game features for the illustrative pull-tab games that include providing a reveal mechanism that displays the symbols in portions of the screen to create player anticipation. Another game feature includes background music that is unique to the game theme. Another game feature may include a sound that is triggered when each symbol is revealed; and the sound may be different for each game. A further game feature includes a prize rollup sound which is common to all games. Yet another game feature includes a celebration sound on all big wins. Additionally, game features may include a change in music during bonus rounds. Another game feature may include a prize rollup on the base game screen after a bonus round. A still further game feature may include symbols that slide in from the side or other such animated presentation. Yet another game feature includes game specific math that complies with jurisdictional Rules and Statutes.

Additionally, the screenshot includes an image of a bingo card 1004 that is assigned to the player by the mobile wagering sub-system 102. The illustrative bingo card 1004 includes twenty-four (24) numbers, a free space in the middle and four (4) randomly located bonus squares. The panel also has a space for displaying ball draw results, termed the bingo display area 1006, from a set of 75 bingo numbers. Additionally, the panel includes a results display area, termed the results summary line 1008, for displaying bingo game results. The largest portion of the illustrative screenshot 1000 includes an entertainment display which is animated and displays the results of the bingo game in an entertaining format. In the embodiment shown the entertainment display portion includes a symbol matrix display 1010, where matching sets of symbols are used to equate to prize values generated from the bingo game.
The illustrative high-speed bingo game is played between players across the network who desire to play the game at approximately the same time. The illustrative high-speed bingo game is played by having the authorized mobile device 112 communicate with the mobile wagering sub-system 102, and the results generated by the mobile wagering sub-system 102 are communicated to the authorized mobile device 112, which presents the bingo game results in an entertaining manner that awards a prized that matches the bingo win.
In the illustrative embodiment, the high-speed bingo game includes two winning patterns, a Four Corner pattern, which is won by the first player (or players) to get all four corners of their bingo card called, and a Small Frame, which is won by the first player (or players) to complete the set of eight squares surrounding the center square. The illustrative game session for a high-speed game is initiated when a player touches the PLAY button to initiate the game session. The next game event includes having the bingo display area 1006 “drop down” and shows a blank bingo card and draw. A message is sent to the mobile wagering sub-system 102 requesting the initiation of a game session. The mobile wagering sub-system 102 determines if other players have made a similar request. If no other player is found in a specified time period then the initial play request is aborted and the cash balance in the player account is refunded the play amount.
If at least one other player is found within a specified wait time, then a bingo card is assigned to each player and the game is played rapidly by the mobile wagering sub-system 102. As an example, the total time for the MWS to process the wager may be under one second. The mobile wagering sub-system 102 then sends game information and results to each participating client. The game information broadcast by the mobile wagering sub-system 102 may include bingo card numbers, the location of bonus squares, color coded ball draw results (green for completion of the Four Corner (4C) game and blue for completion of the Small Frame (SF) game), results summary lines, prize value for each authorized mobile device and other such bingo game information.

The illustrative authorized mobile device 112 includes a touch sensitive display with visual elements that can be pulled or retracted or retracted from the touch sensitive display. For example, a tab may be “up” and not visible as it moves down during the game session to enable the player to see the bingo play and then automatically moves upwards and out of sight when the entertainment display begins. If the player touched the tab to “pull down” the display it may remain down during all phases of the play cycle.
In one example of the Flash Bingo game called Martian Invasion, the prize structure includes prizes for being the first card to complete a winning pattern such as a four (4) Corner Winner may receive 2.5% of the total wagered on the game by all participants and the Small Frame winner may receive 2.5% of the total wagered on the game by all participants. The illustrative Martian Invasion $2 theme may also have bonus prizes as follows:

A Linked Bingo Tournament (LBT) is a variation of high-speed electronic bingo, in which players win prizes based on a series of bingo games played against other players for prize points during a predetermined interval. In the illustrative linked bingo tournament (LBT), players are charged a fee to enter the tournament. Similarly to the high-speed bingo game described above, all bingo games in the tournament are played against other tournament players. In the LBT bingo game winners are awarded points, instead of cash. At the end of the predefined tournament play period, cash prizes are given out to the players that have achieved the highest and/or lowest point scores during the course of the tournament. A pre-determined percent of the entry fees may be allocated for prizes to players.
In the illustrative embodiment, the linked bingo tournament (LBT) sessions are held on scheduled days of the week at specific times. For example, Tuesday evenings between 7:00 and 9:00 may be the schedule time slot for the LBT sessions. Using the Tuesday example, LBT games could begin at 7:00, 7:30, 8:00 and 8:30. The dates and times are scheduled using portal functions that create schedule files in the database of the central system and may be changed from time to time. Notifications of upcoming LBT times may be given to players on their game client devices.

When the player selects a menu item 1110 as shown on
When the player sign up is successful
The screen shown in
Tournament play continues until all players have completed their allotted number of pays or the tournament time expires, at which time a screen appears as shown in
A special provision may be made to cover the case where a player is trying to play a game and cannot complete it because bingo requires a competitor, and all other players may have completed their allotted games. In one illustrative embodiment, the player in that condition receives a predetermined allotment of points.
If the player interacting with the authorized mobile device 112 is a winner, the prize amount may normally be added to the players Cash, unless jurisdictional or IRS rules require special handling. After the tournament game session is completed, the player may cash-out to redeem their prize, or continue playing any offered games. Note, large prizes may be subject to reporting and claim procedures to comply with federal or jurisdictional reporting requirements.
Excitement and player enthusiasm for the illustrative linked bingo tournament (LBT) games are greatly enhanced when the basic game is combined with the video presentation sub-system (VPS) 104, a VPS monitor or stationary monitor 110 and broadcast content that includes player ranking information during the LBT game session or game sessions. For example, the video presentation sub-system 104 may be configured to combine output from the mobile wagering sub-system 102 with commentary from a broadcaster and visual images of the games in play. The video generated by the VPS 104 and presented on the venue VPS monitor or stationary monitor 110 converts an individual bingo gaming experience to a group bingo experience, in which many people in a venue is doing very well and competing against players in other venues in other towns in a visible way, that the local players may enthusiastically support their own player. Expanding the degree of involvement provides a significant way of converting individual game play into a social event that attracts other players.
By way of example and not of limitation, linked bingo tournament (LBT) games have a short duration, e.g. 15 minutes. LBT game count-downs may be shown on the authorized mobile device 112 and the venue's VPS monitor or stationary monitor 110. In the illustrative embodiment, the venue's VPS monitor or stationary monitor 110 may be activated at least 30 minutes before the LBT game session begins and through the duration of the LBT session and for at least 30 minutes after the completion of each LBT game session.
By way example and not of limitation, an illustrative tournament game session may include a game buy-in of $20 so that if a player elects to play the tournament, $20 may be transferred to the authorized mobile device 112 with a POS device 114 as described above. In the illustrative tournament game session, there may be 500 players participating and, thus, based on a fee of $20 per player, the total LBT game sales are: $20×500 persons=$10,000. If a further assumption is made to support an 85% prize pool, the total LBT game prizes awarded may be $8,500. Some of the LBT Game Prizes may be configured to contribute to an LBT Linked Tournament Jackpot, and players participating in an LBT game session may have an opportunity to win those prizes based on achieving a threshold total prize level, or other criteria. That jackpot could be a progressive and the pool would enlarge from tournament to tournament until a player met the winning criteria.
Multiple variants of the LBT may be available for schedule. Some tournament games may have a pay structure similar to the schedule presented below:
In the event of a tie prizes may be divided equally among the players. For example, using the above prize structure, and assuming there are 200 players, and that the 4th and 5th place are tied, then the prize won by each of those players would be: ($340+$272)/2=$306. Rounding rules may be subject to jurisdictional regulations.
In the illustrative tournament bingo game session, the player's entry fee of $20 allows a fixed number of plays (e.g. 80). For each play, the players “Plays” meter 1306 may be decremented by 1. If a player wins a prize, the prize points are added to the “Points” meter 1204. All games are played against another tournament player for each round. Players may randomly compete versus different players on each card, based on timing of game starts. Only winners of the Small Frame or Four Corner games may receive any points. As in regular Flash Bingo, points may be awarded for winning those games and meeting criteria for winning bonus points associated with those wins.
In operation, LBT tournaments may be identified by a specific game icon on the game client Menu screen. Activation of the game requires that the player have sufficient credits to play according to the game rules. Also, a minimum number of participating players entering into the prize pool may be required to initiate a linked bingo tournament game. In the illustrative embodiment, each bingo tournament game session includes of at least two (2) players playing modified Flash Bingo with a standard 24 number bingo card numbered 1 through 75, B-I-N-G-O with a FREE space in the middle. Games are activated by a player pressing PLAY, which initiates play and selects auto-daubing for each round. During the roll-up period prior to the commencement of a linked bingo tournament (LBT) game session, information regarding the total number of player participants and total prize pool for that specific tournament may be exhibited on the player screen and VPS video monitor as shown in

The illustrative screenshot 2200 may be presented on a VPS monitor or stationary monitor 110. During the illustrative tournament game the venue based VPS video monitor or stationary monitor 110 may be configured to present a leader board 2204 to players on a real time basis. The VPS output may also be configured to show the point totals for leading players and identifies the city and venues where the players are playing 2204. Additionally, the VPS video monitor or stationary monitor 110 may display the time remaining in the tournament. In the illustrative embodiment, leading players are identified by a chosen screen name and player selected avatars. The centralized gaming system 100 incorporates a commercially available software filter to avoid use of improper names or initials on the leader board. As described above, the leader board may also be available on player's client devices.
In another illustrative embodiment the video presentation sub-system 104 provides streaming content to support mobile wagering sub-system 102 games, including Tournament Bingo. The video presentation sub-system 104 may be broadcasting 60 minutes, for example, prior to the illustrative linked bingo tournament (LBT) and 30 minutes following the conclusion of tournament sessions. By way of example and not of limitation, the content presented on the VPS video monitor may include: games promotional videos, streaming Flash Bingo Jackpot information, charity promotional videos, advertising and the actual sports-style coverage of the LBT games and bingo games themselves. It should be understood that the time period for a broadcast may be determined by the producers and can be any suitable length of time.

During the linked bingo tournament game session, the leader board information may scroll to show the top scores in the network on a “real-time” basis. This leader board information may be expected to cover a state, or more, depending on the jurisdiction hosting the game. The leader board updates may occur frequently, e.g. every 10 seconds. At the end of the LBT game, the winners, the venue where they played and the prizes won may be broadcast. This information may scroll and could remain on a split screen for a period of time. The top winner(s) may be celebrated. As described above, the prize meter indicates the total prize pool for an upcoming game based on the volume of players enrolling in the LBT.
By way of example and not of limitation, for an illustrative Tournament Bingo games the player is advised in real-time of information about the status of the tournament, including size of the jackpot pool, number of players, leaders (identified by a “handle” and location), and time remaining in the tournament. This data may be enhanced with visual representations and comments from a moderator and field reports. Thus, the player obtains a sense of community and competition which cannot be gained from the client game interface itself.
Another game style related to the Linked Bingo Tournament is Bingo. This is a more traditional style of bingo as compared to the high-speed bingo that is the basis for Flash Bingo and the Linked Bingo Tournaments.
Bingo games may be scheduled in the tournament menus interspersed with linked bingo tournaments. In one example, a tournament series may be scheduled that has four (4) events, namely, two (2) Flash Bingo Tournaments and two (2) Linked bingo games. Each event may take 30 minutes, so the entire session, supported by the VPS would be a two hour session.
The following describes an illustrative implementation of a bingo tournament session. From the tournament menu illustrated in

In operation, the central system 100 sends down messages with the ball draws. As each ball draw is revealed the ball is shown on the screen in space 2610. The game board 2620 displays all called numbers and all player cards are marked on the screen as each ball is called. Balls are called at a settable rate in the central system 100. A typical rate may be one ball each 10 seconds, which is similar to the familiar rate that a ball “caller” in a traditional bingo hall might announce balls as they are drawn. A jackpot value may be displayed in space 2630 and the winning patterns and associated prizes are displayed in area 2640. During the ball call the game client may include audio simulating the voice of a caller calling the balls. In the illustrative embodiment, the game displayed has three winning patterns—a straight line, a large M, and a coverall or “blackout”, meaning that all 24 fillable spaces are called.

The illustrative GLW website server 120 includes a SQL Server database and a software architecture based on .NET, C# and other such computing languages. The illustrative GLW website server 120 is also communicatively coupled to the mobile wagering sub-system (MWS) 102 with an interface that allows players to log into the GLW 120 or the MWS 102 with the same screen name and password. Additionally, the GLW 120 and MWS 102 both support the common use of player-chosen avatars. Note, in the illustrative embodiment there is no requirement for players on the MWS 102 to login with a password, so that anonymous play is fully supported. However if players do desire to identify themselves to the MWS 102 with their GLW 120 screen name and password, then they can have the benefit of having aspects of their play transferred to their GLW account. Information that may be transferred from the GLW 120 to the MWS 102 includes scores of tournament, prize winnings, play totals, play locations, number of play sessions, and other such game information.
In operation, periodic tournament scores may be tracked based on the results from the MWS 102 activity. Additionally, the periodic tournament scores are also available to each player that accesses the GLW website server 120. The type of data collected and corresponding data attributes may vary based upon jurisdictional regulations. In the illustrative embodiment, players may be identified by their chosen screen name and general location. The illustrative website server 120 presents the top players in each region and their corresponding scores and home town.

The GLW 120 and MWS 102 systems are communicatively coupled to the VPS 104, which is communicatively coupled to the VPS video display as shown in
The illustrative gaming systems and methods presented above may include a plurality of server applications that configured to provide high-availability and redundancy, processes all inputs, generates outputs, and maintains a central database for accounting, game play, system configuration data, and other such data types. By way of example and not of limitation, critical system data regarding clients may be maintained a repository associated with the illustrative gaming system. Historical games results and leader board information may be maintained. Printable versions of this information may be available on the portal.
The illustrative client devices described in the illustrative embodiments are communicatively coupled to a gaming system database, which stores client device data. Additionally, the illustrative gaming system database is configured to be secure. Furthermore, the illustrative gaming system database manages the data that is received from client devices in geographically dispersed gaming venues.
The illustrative centralized gaming system may be disposed in a central site as described herein. The illustrative centralized gaming system may process information received over the internet backbone from client devices such as mobile devices, management terminals and other such client devices.
The illustrative MWS sub-system manages the funding of game play and operation of wagering games and overall system management. All gaming messaging between servers and client devices is sent and received over a secure internet network that directs network traffic to the appropriate server elements. A Portal service receives messages from management terminals and provides functionality to authorized users to control the system and access real-time and historical data. All server applications are structured to be deployable in a virtual server environment, configured for high-availability with fail-over capabilities on hardware components and database structures that keep a multiplicity of all data records.
By way of example and not of limitation, the games supported by the wagering system include electronic pull-tabs, linked bingo, high-speed linked bingo with entertainment, bingo tournaments, slot games, video poker, multi-player poker, black-jack, roulette, and other casino or entertainment games.
Many game types, including electronic pull-tabs and the entertainment aspect of linked bingo have bonus modes that award prizes based on a theme-specific animation. Often these features take more play time than a conventional game. While these features are entertaining, many players who have played the games for some period of time find the time spent in animation wasteful. Therefore this system features a unique option at the beginning of any potentially long bonus animation. The player is presented with a screen announcing the bonus and then is presented with an option to proceed with the bonus animation or bypass the animation and go directly to the prize award at the end of the animation.
It is clear that the infrastructure of the MWS with the added capabilities of the VPS can support a wide variety of game types, in addition to the ones described herein. Those games include slot machine games, video lottery games, poker, blackjack, skill-based wagering games, among others.
It should be noted that in jurisdictions that allow gaming outside of physically licensed areas some of the above-mentioned security considerations may be relaxed or replaced by more appropriate mechanisms.
It is to be understood that the detailed description of illustrative embodiments are provided for illustrative purposes. The scope of the claims is not limited to these specific embodiments or examples. Therefore, various process limitations, elements, details, and uses can differ from those just described, or be expanded on or implemented using technologies not yet commercially viable, and yet still be within the inventive concepts of the present disclosure. The scope of the invention is determined by the following claims and their legal equivalents.
