Patent Application
20240153341
The present application concerns workflow improvements for a hosted gaming environment to provide improved flexibility, scalability, and data security. In particular, a hosted gaming platform may be used to provide backend data services, such as the determination of spin results for slot-based games, to a number of different players and/or for a number of different games, while maintaining a consistent and seamless user experience.
Electronic gaming devices, such as electronic gaming machines (EGMs), computers, or other mobile devices, can provide a variety of wagering games such as slot games, video poker games, video blackjack games, roulette games, video bingo games, keno games and other types of games that are frequently offered at casinos and other locations. Play on electronic gaming devices typically involves a player establishing a credit balance by inputting money, or another form of monetary credit and placing a monetary wager (from the credit balance) on one or more outcomes of an instance (or single play) of a primary or base game.
“Slot”-type games are often displayed to the player in the form of various symbols arrayed in a row-by-column grid or matrix. Specific matching combinations of symbols along predetermined paths (or paylines) through the matrix indicate the outcome of the game. The display typically highlights winning combinations/outcomes for identification by the player. Matching combinations and their corresponding awards are usually shown in a “pay-table” which is available to the player for reference. Often, the player may vary his/her wager to include differing numbers of paylines and/or the amount bet on each line. By varying the wager, the player may sometimes alter the frequency or number of winning combinations, frequency or number of secondary games, and/or the amount awarded.
Typical games use a random number generator (RNG) to randomly determine the outcome of each game. The game is designed to return a certain percentage of the amount wagered back to the player over the course of many plays or instances of the game, which is generally referred to as return to player (RTP). The RTP and randomness of the RNG ensure the fairness of the games and are highly regulated. Upon initiation of play, the RNG randomly determines a game outcome and symbols are then selected which correspond to that outcome. Notably, some games may include an element of skill on the part of the player and are therefore not entirely random.
Slot games and other wagering games may be developed by many different gaming studios, and such games may have many concerns in common, such as updatability, auditability (e.g., from a regulatory standpoint), and data accuracy. Thus, it would be beneficial, from both a game development and user experience standpoint, to provide a novel hosted gaming environment with improved flexibility, scalability, and data security/integrity. In particular, a hosted gaming platform may be used to provide various backend data services, such as the determination of spin results for slot-based games (and/or the determination of other random-based outcomes for other types of wagering games), to a number of different players and/or for a number of different games, while maintaining a consistent and seamless user experience, e.g., a user experience that is able to mimic the responsiveness and “look and feel” of purely local, i.e., client device-based, wagering games.
The disclosed technology is directed to several features of electronic gaming devices and hosted gaming platforms for hosting games to be played on such electronic gaming devices. For example, a hosted gaming platform may involve the use of various components, such as: service adapters; storage adapters; and game backend systems (e.g., slot game backends). These components may be intentionally sandboxed from each other, thereby allowing them to execute without interdependence on one another, and providing game developers the ability to use different version libraries, thereby allowing a more flexible development environment for game developers. In some embodiments, the hosted gaming platform may have an improved technical design, such that modifications may be made, e.g., by developers, to one or more of: the service adapter; the storage adapter; or the game backend systems-without causing a need to recompile the other unmodified portions of the backend platform. By controlling the formatting and transmission protocols of all incoming and outgoing game-related data to the hosted gaming platform, additional data security and integrity may be achieved via the use of the hosted gaming platform.
In one example of the various features disclosed herein, the spin profile of a hosted slot-based game may be modified, such that a server's generation of the spin results for a round of game play (which includes the round trip time for the request of the spin results to travel from a client device to the server and then the results to be received back to the client device) may be timed so as to arrive at the client device during a first reel spin duration of the round of gameplay at the client device. In that way, the gameplay presented to a user is seamless, e.g., it does not appear to lag or delay on the first reel spin while waiting for the gameplay server to generate the spin results.
In another example of the various features disclosed herein, the hosted slot-based game may allow for fully asynchronous spin requests, e.g., especially in the case of so-called “social” or non-real money gaming. For example, rather than waiting after each spin result to get a response from an external player account management (PAM) system as to a player's current credit balance before proceeding to the next spin, the hosted game may track and update the player's credit balance during the session- and then update the player's balance with the external PAM at the end of the gameplay session.
In yet another example of the various features disclosed herein, the hosted slot-based game may allow for asynchronous clear recovery requests, i.e., requests that specify that recovery data for the current round of gameplay may be discarded. For example, rather than waiting after each spin result to get a clear recovery response from a client device confirming that the server may begin spinning the next round of gameplay, the server may also begin spinning the next round once a player has requested the spin of the next round (i.e., even if the server never received the clear recovery message).
In still another example, a player may be presented with a “stop spin” request UI element during a gameplay session, wherein the stop spin request is able to be selected by a player and sent to a gameplay server before the results for the current spin have been produced by the server. In such cases where a stop spin request is submitted by a player, the first reel spin duration of the current round of gameplay may be configured to be extended at least until the client receives the spin results for the current spin. Preferably, the client may be further configured to provide a graphical indication that the stop spin request may be requested by the client device (e.g., a change in color, size, shape, positioning, labeling, etc. of the stop spin request UI element).
The innovations disclosed herein can be implemented as part of a method, as part of an electronic gaming device, such as an EGM or mobile device, or on an electronic gaming server or other computer server(s) configured to perform the method, or as part of non-transitory computer-readable media storing computer-executable instructions for causing one or more processors in a computer system to perform the method. The various innovations can be used in combination or separately. This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. The foregoing and other objects, features, and advantages of the invention will become more apparent from the following detailed description, which proceeds with reference to the accompanying figures and illustrates a number of examples. Examples may also be capable of other and different applications, and some details may be modified in various respects all without departing from the spirit and scope of the disclosed innovations.
The detailed description presents innovations in electronic gaming machines (“EGMs”) and other electronic gaming devices and computer-implemented systems. Various alternatives to the examples described herein are possible. For example, some of the methods described herein can be altered by changing the ordering of the method acts described, by splitting, repeating, or omitting certain method acts, etc. The various aspects of the disclosed technology can be used in combination or separately. Some of the innovations described herein address one or more of the problems noted in the background. Typically, a given technique/tool does not solve all such problems. It is to be understood that other examples may be utilized and that structural, logical, software, hardware, and electrical changes may be made without departing from the scope of the disclosure. The following description is, therefore, not to be taken in a limited sense. Rather, the scope of the present disclosure is defined by the appended claims.
The innovations described herein may, among other things: execute a hosted gaming platform, wherein the hosted gaming platform comprises at least a spin request module; receive, at the hosted gaming platform, a first spin request from a current round of a first gameplay session executing at a frontend gaming client, wherein the first spin request comprises at least session metadata and an identifier for a first user; and then, in response to the first spin request, execute, using at least the spin request module, the first spin request to produce one or more spin results, wherein the execution of the first spin request is based, at least in part, on the session metadata and the identifier for the first user. Finally, the one or more spin results may be returned to the frontend gaming client, wherein the one or more spin results arrive at the frontend gaming client during a first reel spin duration of the first gameplay session at the frontend gaming client.
In some embodiments, the hosted gaming platform may be configured to: maintain a session credit balance for the first gameplay session in response to each spin request received from the first gameplay session; and update, upon conclusion of the first gameplay session, a current credit balance for the first user based on the maintained session credit balance for the first gameplay session. In some such embodiments, the current credit balance (e.g., in terms of a real money value or a non-real money value) for the first user may be updated at a player account management (PAM) system that is external to the hosted gaming platform.
In other embodiments, the hosted gaming platform may be configured to discard the recovery data for the current round of the first gameplay session in response to receiving a second spin request from the first gameplay session.
In still other embodiments, the hosted gaming platform may be configured to receive a stop spin request during the current round of the first gameplay session, wherein the stop spin request is received before the one or more spin results for the first spin request have been produced, and wherein the first reel spin duration of the first gameplay session at the frontend gaming client is configured to be extended at least until the frontend gaming client receives the one or more spin results for the first spin request. In some such embodiments, the frontend gaming client is further configured to provide a graphical indication that the stop spin request may be requested by the client device.
Communication between the gaming devices 104A-104X and the server computers 102, and among the gaming devices 104A-104X, may be direct or indirect using one or more communication protocols. As an example, gaming devices 104A-104X and the server computers 102 can communicate over one or more communication networks, such as over the Internet, through a website maintained by a computer on a remote server, or over an online data network, including commercial online service providers, Internet service providers, private networks (e.g., local area networks and enterprise networks), and the like (e.g., wide area networks). The communication networks could allow gaming devices 104A-104X to communicate with one another and/or the server computers 102 using a variety of communication-based technologies, such as radio frequency (RF) (e.g., wireless fidelity (WiFi®) and Bluetooth®), cable TV, satellite links and the like.
In some implementations, server computers 102 may not be necessary and/or preferred. For example, in one or more implementations, a stand-alone gaming device such as gaming device 104A, gaming device 104B or any of the other gaming devices 104C-104X can implement one or more aspects of the present disclosure while connected locally to a machine hosting the aforementioned gaming platform. In some such cases, the local machine(s) hosting the gaming platform may be within the gaming device 104. However, it is typical to find multiple electronic gaming devices connected to networks implemented with one or more of the different server computers 102 described herein.
The server computers 102 may include an outcome determination server 106, e.g., a central determination gaming system server, a multimedia content distribution server, or other type of backend server (examples of which will be discussed in greater detail below), a ticket-in-ticket-out (TITO) system server 108, a player tracking system server 110, a progressive system server 112, and/or a casino management system server 114. Gaming devices 104A-104X may include features to enable operation of any or all servers for use by the player and/or operator (e.g., the casino, resort, gaming establishment, tavern, pub, etc.). For example, game outcomes may be generated on an outcome determination server 106 and then transmitted over the network to any of a group of remote terminals or remote gaming devices 104A-104X that utilize the game outcomes and display the results to the players.
Gaming device 104A is often of a cabinet construction which may be aligned in rows or banks of similar devices for placement and operation on a casino floor. The gaming device 104A often includes a main door which provides access to the interior of the cabinet. Gaming device 104A typically includes a button area or button deck 120 accessible by a player that is configured with input switches or buttons 122, an access channel for a bill validator 124, and/or an access channel for a ticket-out printer 126.
In
In many configurations, the gaming device 104A may have a main display 128 (e.g., video display monitor) mounted to, or above, the gaming display area 118. The main display 128 can be a high-resolution liquid crystal display (LCD), plasma, light emitting diode (LED), or organic light emitting diode (OLED) panel which may be flat or curved as shown, a cathode ray tube, or other conventional electronically controlled video monitor.
In some implementations, the bill validator 124 may also function as a “ticket-in” reader that allows the player to use a casino issued credit ticket to load credits onto the gaming device 104A (e.g., in a cashless ticket (“TITO”) system). In such cashless implementations, the gaming device 104A may also include a “ticket-out” printer 126 for outputting a credit ticket when a “cash out” button is pressed. Cashless TITO systems are used to generate and track unique bar-codes or other indicators printed on tickets to allow players to avoid the use of bills and coins by loading credits using a ticket reader and cashing out credits using a ticket-out printer 126 on the gaming device 104A. The gaming device 104A can have hardware meters for purposes including ensuring regulatory compliance and monitoring the player credit balance. In addition, there can be additional meters that record the total amount of money wagered on the gaming device, total amount of money deposited, total amount of money withdrawn, total amount of winnings on gaming device 104A.
In some implementations, a player tracking card reader 144, a transceiver for wireless communication with a mobile device (e.g., a player's smartphone), a keypad 146, and/or an illuminated display 148 for reading, receiving, entering, and/or displaying player tracking information is provided in gaming device 104A. In such implementations, a game controller within the gaming device 104A can communicate with the player tracking system server 110 to send and receive player tracking information.
Gaming device 104A may also include a bonus topper wheel 134. When bonus play is triggered (e.g., by a player achieving a particular outcome or set of outcomes in the primary game), bonus topper wheel 134 is operative to spin and stop with indicator arrow 136 indicating the outcome of the bonus game. Bonus topper wheel 134 is typically used to play a bonus game, but it could also be incorporated into play of the base or primary game.
A candle 138 may be mounted on the top of gaming device 104A and may be activated by a player (e.g., using a switch or one of buttons 122) to indicate to operations staff that gaming device 104A has experienced a malfunction or the player requires service. The candle 138 is also often used to indicate a jackpot has been won and to alert staff that a hand payout of an award may be needed.
There may also be one or more information panels 152 which may be a back-lit, silkscreened glass panel with lettering to indicate general game information including, for example, a game denomination (e.g., $0.25 or $1), pay lines, pay tables, and/or various game related graphics. In some implementations, the information panel(s) 152 may be implemented as an additional video display.
Gaming devices 104A have traditionally also included a handle 132 typically mounted to the side of main cabinet 116 which may be used to initiate game play.
Many or all the above described components can be controlled by circuitry (e.g., a game controller) housed inside the main cabinet 116 of the gaming device 104A, the details of which are shown in
An alternative example gaming device 104B illustrated in
Example gaming device 104B includes a main cabinet 116 including a main door which opens to provide access to the interior of the gaming device 104B. The main or service door is typically used by service personnel to refill the ticket-out printer 126 and collect bills and tickets inserted into the bill validator 124. The main or service door may also be accessed to reset the machine, verify and/or upgrade the software, and for general maintenance operations.
Another example gaming device 104C shown is the Helix™ model gaming device manufactured by Aristocrat© Technologies, Inc. Gaming device 104C includes a main display 128A that is in a landscape orientation. Although not illustrated by the front view provided, the main display 128A may have a curvature radius from top to bottom, or alternatively from side to side. In some implementations, main display 128A is a flat panel display. Main display 128A is typically used for primary game play while secondary display 128B is typically used for bonus game play, to show game features or attraction activities while the game is not in play or any other information or media desired by the game designer or operator. In some implementations, example gaming device 104C may also include speakers 142 to output various audio such as game sound, background music, etc.
Many different types of games, including mechanical slot games, video slot games, video poker, video black jack, video pachinko, keno, bingo, and lottery, may be provided with or implemented within the depicted gaming devices 104A-104C and other similar gaming devices. Each gaming device may also be operable to provide many different games. Games may be differentiated according to themes, sounds, graphics, type of game (e.g., slot game vs. card game vs. game with aspects of skill), denomination, number of paylines, maximum jackpot, progressive or non-progressive, bonus games, and may be deployed for operation in Class 2 or Class 3, etc.
The games available for play on the gaming device 200 are controlled by a game controller 202 that includes one or more processors 204. Processor 204 represents a general-purpose processor, a specialized processor intended to perform certain functional tasks, or a combination thereof. As an example, processor 204 can be a central processing unit (CPU) that has one or more multi-core processing units and memory mediums (e.g., cache memory) that function as buffers and/or temporary storage for data. Alternatively, processor 204 can be a specialized processor, such as an application specific integrated circuit (ASIC), graphics processing unit (GPU), field-programmable gate array (FPGA), digital signal processor (DSP), or another type of hardware accelerator. In another example, processor 204 is a system on chip (SoC) that combines and integrates one or more general-purpose processors and/or one or more specialized processors. Although
Memory 208 can store one or more game programs 206 that provide program instructions and/or data for carrying out various implementations (e.g., game mechanics) described herein. Stated another way, game program 206 represents an executable program stored in any portion or component of memory 208. In one or more implementations, game program 206 is embodied in the form of source code that includes human-readable statements written in a programming language or machine code that contains numerical instructions recognizable by a suitable execution system, such as a processor 204 in a game controller or other system. Examples of executable programs include: (1) a compiled program that can be translated into machine code in a format that can be loaded into a random access portion of memory 208 and run by processor 204; (2) source code that may be expressed in proper format such as object code that is capable of being loaded into a random access portion of memory 208 and executed by processor 204; and (3) source code that may be interpreted by another executable program to generate instructions in a random access portion of memory 208 to be executed by processor 204.
Alternatively, game programs 206 can be set up to generate one or more game instances based on instructions and/or data that gaming device 200 exchanges with one or more remote gaming devices, such as an outcome determination server 106 (also shown in
In some embodiments, the outcome determination server 106 may comprise a multi-threaded architecture, allowing multiple connections and/or game instances to utilize the outcome determination server 106. In some implementations, e.g., wherein the outcome determination server 106 is hosted at a cloud service provider, the amount of resources at the cloud service provider that are dedicated to a particular game (e.g., number of servers, number of threads, amount of memory, bandwidth, etc.) may be scaled dynamically to accommodate the real-time needs of the hosted game. When a game is stored on gaming device 200, it may be loaded from memory 208 (e.g., from a read only memory (ROM)) or from the outcome determination server 106 to memory 208.
Gaming devices, such as gaming device 200, are highly regulated to ensure fairness and, in many cases, gaming device 200 is operable to award monetary awards (e.g., typically dispensed in the form of a redeemable voucher). Therefore, to satisfy security and regulatory requirements in a gaming environment, hardware and software architectures are implemented in gaming devices 200 that differ significantly from those of general-purpose computers. Adapting general purpose computers to function as gaming devices 200 is not simple or straightforward because of: (1) the regulatory requirements for gaming devices 200, (2) the harsh environment in which gaming devices 200 operate, (3) security requirements, (4) fault tolerance requirements, and (5) the requirement for additional special purpose componentry enabling functionality of an EGM. These differences require substantial engineering effort with respect to game design implementation, game mechanics, hardware components, and software.
One regulatory requirement for games running on gaming device 200 generally involves complying with a certain level of randomness. Typically, gaming jurisdictions mandate that gaming devices 200 satisfy a minimum level of randomness without specifying how a gaming device 200 should achieve this level of randomness. To comply,
In
Another regulatory requirement for running games on gaming device 200 includes ensuring a certain level of RTP. Similar to the randomness requirement discussed above, numerous gaming jurisdictions also mandate that gaming device 200 provides a minimum level of RTP (e.g., RTP of at least 75%). A game can use one or more lookup tables (also called weighted tables) as part of a technical solution that satisfies regulatory requirements for randomness and RTP. In particular, a lookup table can integrate game features (e.g., trigger events for special modes or bonus games; newly introduced game elements such as extra reels, new symbols, or new cards; stop positions for dynamic game elements such as spinning reels, spinning wheels, or shifting reels; or card selections from a deck) with random numbers generated by one or more RNGs, so as to achieve a given level of volatility for a target level of RTP. (In general, volatility refers to the frequency or probability of an event such as a special mode, payout, etc. For example, for a target level of RTP, a higher-volatility game may have a lower payout most of the time with an occasional bonus having a very high payout, while a lower-volatility game has a steadier payout with more frequent bonuses of smaller amounts.) Configuring a lookup table can involve engineering decisions with respect to how RNG outcomes are mapped to game outcomes for a given game feature, while still satisfying regulatory requirements for RTP. Configuring a lookup table can also involve engineering decisions about whether different game features are combined in a given entry of the lookup table or split between different entries (for the respective game features), while still satisfying regulatory requirements for RTP and allowing for varying levels of game volatility.
When a player wishes to play the gaming device 200, he/she can insert cash or a ticket voucher through a coin acceptor (not shown) or bill validator 234 to establish a credit balance on the gaming device. The credit balance is used by the player to place wagers on instances of the game and to receive credit awards based on the outcome of winning instances. The credit balance is decreased by the amount of each wager and increased upon a win. The player can add additional credits to the balance at any time. The player may also optionally insert a loyalty club card into the card reader 230. During the game, the player views with one or more UIs, the game outcome on one or more of the primary game display 240 and secondary game display 242. Other game and prize information may also be displayed.
For each game instance, a player may make selections, which may affect play of the game. For example, the player may vary the total amount wagered by selecting the amount bet per line and the number of lines played. In many games, the player is asked to initiate or select options during course of game play (such as spinning a wheel to begin a bonus round or select various items during a feature game). The player may make these selections using the player-input buttons 236, the primary game display 240 which may be a touch screen, or using some other device which enables a player to input information into the gaming device 200.
During certain game events, the gaming device 200 may display visual and auditory effects that can be perceived by the player. These effects add to the excitement of a game, which makes a player more likely to enjoy the playing experience. Auditory effects include various sounds that are projected by the speakers 220. Visual effects include flashing lights, strobing lights or other patterns displayed from lights on the gaming device 200 or from lights behind the information panel 152 (
When the player is done, he/she cashes out the credit balance (typically by pressing a cash out button to receive a ticket from the ticket printer 222). The ticket may be “cashed-in” for money or inserted into another machine to establish a credit balance for play.
Additionally, or alternatively, gaming devices 104A-104X and 200 can include or be coupled to one or more wireless transmitters, receivers, and/or transceivers (not shown in
Although
According to some examples, the mobile gaming devices 256 may be configured for stand-alone determination of game outcomes. However, in some alternative implementations the mobile gaming devices 256 may be configured to receive game outcomes from another device, such as the outcome determination server 106, one of the EGMs 104, etc.
Some mobile gaming devices 256 may be configured to accept monetary credits from a credit or debit card, via a wireless interface (e.g., via a wireless payment app), via tickets, via a patron casino account, etc. However, some mobile gaming devices 256 may not be configured to accept monetary credits via a credit or debit card. Some mobile gaming devices 256 may include a ticket reader and/or a ticket printer whereas some mobile gaming devices 256 may not, depending on the particular implementation.
In some implementations, the casino 251 may include one or more kiosks 260 that are configured to facilitate monetary transactions involving the mobile gaming devices 256, which may include cash out and/or cash in transactions. The kiosks 260 may be configured for wired and/or wireless communication with the mobile gaming devices 256. The kiosks 260 may be configured to accept monetary credits from casino patrons 262 and/or to dispense monetary credits to casino patrons 262 via cash, a credit or debit card, via a wireless interface (e.g., via a wireless payment app), via tickets, etc. According to some examples, the kiosks 260 may be configured to accept monetary credits from a casino patron and to provide a corresponding amount of monetary credits to a mobile gaming device 256 for wagering purposes, e.g., via a wireless link such as a near-field communications link. In some such examples, when a casino patron 262 is ready to cash out, the casino patron 262 may select a cash out option provided by a mobile gaming device 256, which may include a real button or a virtual button (e.g., a button provided via a graphical user interface) in some instances. In some such examples, the mobile gaming device 256 may send a “cash out” signal to a kiosk 260 via a wireless link in response to receiving a “cash out” indication from a casino patron. The kiosk 260 may provide monetary credits to the casino patron 262 corresponding to the “cash out” signal, which may be in the form of cash, a credit ticket, a credit transmitted to a financial account corresponding to the casino patron, etc.
In some implementations, a cash-in process and/or a cash-out process may be facilitated by the TITO system server 108. For example, the TITO system server 108 may control, or at least authorize, ticket-in and ticket-out transactions that involve a mobile gaming device 256 and/or a kiosk 260.
Some mobile gaming devices 256 may be configured for receiving and/or transmitting player loyalty information. For example, some mobile gaming devices 256 may be configured for wireless communication with the player tracking system server 110. Some mobile gaming devices 256 may be configured for receiving and/or transmitting player loyalty information via wireless communication with a patron's player loyalty card, a patron's smartphone, etc.
According to some implementations, a mobile gaming device 256 may be configured to provide safeguards that prevent the mobile gaming device 256 from being used by an unauthorized person. For example, some mobile gaming devices 256 may include one or more biometric sensors and may be configured to receive input via the biometric sensor(s) to verify the identity of an authorized patron. Some mobile gaming devices 256 may be configured to function only within a predetermined or configurable area, such as a casino gaming area.
In this example, a gaming data center 276 includes various devices that are configured to provide online wagering games via the networks 417. The gaming data center 276 is capable of communication with the networks 417 via the gateway 272, including and one or more workstations 286a. In this example, switches 278 and routers 280 are configured to provide network connectivity for devices of the gaming data center 276, including storage devices 282a, servers 284a and one or more workstations 570a. The servers 284a may, for example, be configured to provide access to a library of games for online game play. In some examples, code for executing at least some of the games may initially be stored on one or more of the storage devices 282a. The code may be subsequently loaded onto a server 284a after selection by a player via an EUD and communication of that selection from the EUD via the networks 417. The server 284a onto which code for the selected game has been loaded may provide the game according to selections made by a player and indicated via the player's EUD. In other examples, code for executing at least some of the games may initially be stored on one or more of the servers 284a. Although only one gaming data center 276 is shown in
In this example, a financial institution data center 270 is also configured for communication via the networks 417. Here, the financial institution data center 270 includes servers 284b, storage devices 282b, and one or more workstations 286b. According to this example, the financial institution data center 270 is configured to maintain financial accounts, such as checking accounts, savings accounts, loan accounts, etc. In some implementations one or more of the authorized users 274a-274c may maintain at least one financial account with the financial institution that is serviced via the financial institution data center 270.
According to some implementations, the gaming data center 276 may be configured to provide online wagering games in which money may be won or lost. According to some such implementations, one or more of the servers 284a may be configured to monitor player credit balances, which may be expressed in game credits, in currency units, or in any other appropriate manner. In some implementations, the server(s) 284a may be configured to obtain financial credits from and/or provide financial credits to one or more financial institutions, according to a player's “cash in” selections, wagering game results and a player's “cash out” instructions. According to some such implementations, the server(s) 284a may be configured to electronically credit or debit the account of a player that is maintained by a financial institution, e.g., an account that is maintained via the financial institution data center 270. The server(s) 284a may, in some examples, be configured to maintain an audit record of such transactions.
In some alternative implementations, the gaming data center 276 may be configured to provide online wagering games for which credits may not be exchanged for cash or the equivalent. In some such examples, players may purchase game credits for online game play, but may not “cash out” for monetary credit after a gaming session. Moreover, although the financial institution data center 270 and the gaming data center 276 include their own servers and storage devices in this example, in some examples the financial institution data center 270 and/or the gaming data center 276 may use offsite “cloud-based” servers and/or storage devices. In some alternative examples, the financial institution data center 270 and/or the gaming data center 276 may rely entirely on cloud-based servers. In still other examples, one or more third party cloud-based service providers may be utilized by a given casino, a given game developer, or given game studio to host backend game functionality for a number of different games (and/or a number of different players) simultaneously, according to a general service architecture and flexible backend platform design implementing a novel GDK to enhance and componentize game development.
One or more types of devices in the gaming data center 276 (or elsewhere) may be capable of executing middleware, e.g., for data management and/or device communication. Authentication information, player tracking information, etc., including but not limited to information obtained by EUDs 264 and/or other information regarding authorized users of EUDs 264 (including but not limited to the authorized users 274a-274c), may be stored on storage devices 282 and/or servers 284. Other game-related information and/or software, such as information and/or software relating to leaderboards, players currently playing a game, game themes, game-related promotions, game competitions, etc., also may be stored on storage devices 282 and/or servers 284. In some implementations, some such game-related software may be available as “apps” and may be downloadable (e.g., from the gaming data center 276) by authorized users.
In some examples, authorized users and/or entities (such as representatives of gaming regulatory authorities) may obtain gaming-related information via the gaming data center 276. One or more other devices (such EUDs 264 or devices of the gaming data center 276) may act as intermediaries for such data feeds. Such devices may, for example, be capable of applying data filtering algorithms, executing data summary and/or analysis software, etc. In some implementations, data filtering, summary and/or analysis software may be available as “apps” and downloadable by authorized users.
The UI system 302 includes one or more UIs that a player can interact with. The UI system 302 could include one or more game play UIs 304, one or more bonus game play UIs 308, and one or more multiplayer UIs 312, where each UI type includes one or more mechanical UIs and/or graphical UIs (GUIs). In other words, game play UI 304, bonus game play UI 308, and the multiplayer UI 312 may utilize a variety of UI elements, such as mechanical UI elements (e.g., physical “spin” button or mechanical reels) and/or GUI elements (e.g., virtual reels shown on a video display or a virtual button deck) to receive player inputs and/or present game play to a player. Using
The game play UI 304 represents a UI that a player typically interfaces with for a base game. During a game instance of a base game, the game play UI elements 306A-306N (e.g., GUI elements depicting one or more virtual reels) are shown and/or made available to a user. In a subsequent game instance, the UI system 302 could transition out of the base game to one or more bonus games. The bonus game play UI 308 represents a UI that utilizes bonus game play UI elements 310A-310N for a player to interact with and/or view during a bonus game. In one or more implementations, at least some of the game play UI element 306A-306N are similar to the bonus game play UI elements 310A-310N. In other implementations, the game play UI element 306A-306N can differ from the bonus game play UI elements 310A-310N.
Based on the player inputs, the UI system 302 could generate RNG calls to a game processing backend system 314. As an example, the UI system 302 could use one or more application programming interfaces (APIs) to generate the RNG calls. To process the RNG calls, the RNG engine 316 could utilize gaming RNG 318 and/or non-gaming RNGs 319A-319N. Gaming RNG 318 could corresponds to RNG 212 or hardware RNG 244 shown in
The RNG conversion engine 320 processes each RNG outcome from RNG engine 316 and converts the RNG outcome to a UI outcome that is feedback to the UI system 302. With reference to
After generating the UI outcome, the game processing backend system 314 sends the UI outcome to the UI system 302. (As mentioned above, in embodiments wherein aspects of the game's functionality are hosted by a backend server, the UI outcomes may be determined by the hosted game backend and then returned to the game via an application service layer so that the game application may update the appropriate audio and/or visual gameplay elements.) Examples of UI outcomes are symbols to display on a video reel or reel stops for a mechanical reel. In one example, if the UI outcome is for a base game, the UI system 302 updates one or more game play UI elements 306A-306N, such as symbols, for the game play UI 304. In another example, if the UI outcome is for a bonus game, the UI system could update one or more bonus game play UI elements 310A-310N (e.g., symbols) for the bonus game play UI 308. In response to updating the appropriate UI, the player may subsequently provide additional player inputs to initiate a subsequent game instance that progresses through the game processing pipeline.
According to some embodiments, a hosted gaming environment may be comprised of multiple open APIs, whose purpose is to expose the math and game logic of different games to different services, such as storage and the game itself. One aim of the hosted gaming platform architecture is to be able supply functionality to the game/application service client with horizontally-scalable services and the ability to operate across multiple platforms, technology stacks, machines, interfaces, etc. According to some embodiments, the backend host platform can facilitate several different backends that are either functionally separate or are physically distinct from one another.
According to some embodiments, the hosted gaming platform may comprise a service adapter; one or more storage adapters configured to connect and obtain/store data in one or more external databases; and one or more individual game backend systems. The role of service adapter, according to some embodiments, is to contain the business logic for interacting with an application's backend service, dependency services, and associated games. The role of a storage adapter, according to some embodiments, is to be able to interface with the game's respective storage system (e.g., various types of external databases). Finally, the role of the game backends, according to some embodiments, is to encapsulates the business logic for a given service, including core concepts, such as the state machine, Par sheets, and/or mathematical calculations needed for a given application/game.

As shown by arrows 405, according to some embodiments, each virtual reel may come to a stop in a successive order, i.e., to mimic the behavior of a traditional mechanical reel set. For example, a given spin may start out by each of the exemplary virtual reels 1-5 (4041 . . . 404n) spinning at the same time for what is referred to herein as the “reel spin duration.” Then, one-by-one, each virtual reel may come to a stop over a duration of time (also referred to herein as a “stop delay”), i.e., Reel 1 may decelerate and come to a stop, followed by Reel 2 decelerating and coming to a stop, and so on, until Reel 5 decelerates and comes to a stop. In some embodiments, one or more of the virtual reels, e.g., the final reel, may come to a “bounce” stop, e.g., if it is desired to more accurately mimic a mechanical reel coming to a stop, wherein the bounce duration is measured as the reel displacement time from the stop position. Thus, according to some embodiments, the total time duration for a reel spin may be calculated as the: (reel spin duration)+(n*stop delay)+(bounce duration), wherein n=the number of virtual reels used in the spin. It is to be understood that this equation is merely one possible embodiment, and each game could, e.g., have no bounce effect on one or more reels, have game-specific spin profiles, have its own business logic behind how long each reel is set to spin for etc.
Turning now to Timeline 1 (406), a representation of an exemplary spin profile, wherein all outcome determination is performed locally at a client gaming device, is illustrated. As shown in Timeline 1, the initial determination of the spin result (407), e.g., as performed by a RNG and one or more lookup tables, may only take a few milliseconds to perform. At this point, the entire outcome for the current round of gameplay is known to the device, and the remaining animations are purely to provide gameplay features, realism, and/or enhanced enjoyment to the player. Next, a reel spin animation may be performed, wherein all virtual reels spin for a first predetermined amount of time, e.g., 0.6 seconds. Next, each reel may come to a stop in succession, wherein, e.g., the stop delay for each virtual reel may take a second predetermined amount of time, e.g., 0.5 seconds. Finally, there may be a bounce duration of, e.g., 0.2 seconds on the final reel, bringing the total time duration for a reel spin according to exemplary Timeline 1 to approximately 3.3 seconds. In various embodiments, spin result 407 may comprise stop positions for each of the reels 404n, e.g., as determined by a RNG.
Turning now to Timeline 2 (408), a representation of an exemplary client/server-based spin profile, wherein all outcome determination is performed remotely at a hosting gaming server, is illustrated. As shown in Timeline 2, an initial reel spin animation may be performed, wherein all virtual reels spin for at least a first predetermined amount of time, e.g., 0.6 seconds. Next, a spin request may be sent form the client gaming device to the hosted gaming server, the requested outcome may be generated by the server, and then returned to the client device. The duration of time it takes for this sequence of events to take place is also referred to herein as a “sever round trip” (409). In this example, the server round trip may take, e.g., 0.2 seconds, during which the reels must continue to spin (since no outcome for the spin has been determined yet), thereby bringing the total reel spin duration to 0.8 seconds (i.e., 0.6 seconds+0.2 seconds). Next, as with the Timeline 1 example, each reel may come to a stop in succession, wherein, e.g., the stop delay for each virtual reel is again 0.5 seconds. Finally, there may be a bounce duration of, e.g., 0.2 seconds on the final reel, bringing the total time duration for a reel spin according to exemplary Timeline 2 to approximately 3.5 seconds. As may now be appreciated, the total spin duration in Timeline 2 is extended by approximately the amount of time it takes to complete the server round trip operation and retrieve the outcome for the current spin. As may be appreciated, due to various factors, such as network quality, bandwidth availability, server workload, etc., the server round trip could take substantially longer than the 0.2 seconds used in this example, which may cause the initial reel spin to last an undesirable amount of time for the player.
Thus, turning now to Timeline 3 (410), a representation of an exemplary “early start” client/server-based spin profile, wherein all outcome determination is performed remotely at a hosting gaming server, is illustrated. As shown in Timeline 3, the initial reel spin animation may again be performed, wherein all virtual reels spin for at least a first predetermined amount of time, e.g., 0.6 seconds. However, according to Timeline 3, concurrently with the initiation of the initial reel spin animation, a spin request may be sent form the client gaming device to the hosted gaming server, so that the requested outcome may be generated by the server, and then returned to the client device. In this way, if the sever round trip happens to again take 0.2 seconds (as shown in 411), then this server round trip delay may be “hidden” entirely within the 0.6 seconds of the initial reel spin animation. As may now be appreciated, the embodiment of Timeline 3 provides wide latitude in server round trip response times, during which the results of the current spin may be presented to the player without the player experiencing any noticeable delay in the reel spin animation. As another example, if the sever round trip happens to take 0.55 seconds (as shown in 412), then this server round trip delay may also be hidden entirely within the 0.6 seconds of the initial reel spin animation. However, it is to be appreciated that there may be some server round trip times (e.g., as shown in 413) that are so long that the client device will either need to extend the initial reel spin duration (e.g., beyond a preferred maximum duration of, say, 0.6 seconds), or provide some other “time out” or “error” message notification to the player (e.g., in the event that a network connection has been lost, information regarding the spin outcome was dropped or corrupted during transmission, etc.). Next, as with the Timeline 1 example, each reel may come to a stop in succession, wherein, e.g., the stop delay for each virtual reel is again 0.5 seconds. Finally, there may be a bounce duration of, e.g., 0.2 seconds on the final reel, bringing the total time duration for a reel spin according to exemplary Timeline 3 back down to approximately 3.3 seconds (again, assuming that the entire server round trip delay was able to be successfully hidden within the initial reel spin animation duration).

Turning first to client-based architecture 500, a client device 502 may communicate directly with a PAM 504 for any credit balance updates, requests for new spins, etc. In the exemplary process flow diagram illustrated for client-based architecture 500, client 502 may begin by sending a spin request (506) to the PAM 504, e.g., to indicate to the PAM that the player is about to play another round of the current game. However, in the client-based architecture 500, the determination of the outcome of the current round of gameplay (508) may take place entirely at the client device. Then, once a balance update confirmation has been received from the PAM (510), a clear recovery request (512) may be triggered by the client device, thereby allowing the client device to proceed with the next spin (514), thus beginning the next round of gameplay.
By contrast, in client/server-based architecture 550, a client device 552 may communicate directly with a server 554, which server may communicate, if necessary, with an external PAM 556 for any credit balance updates. In the exemplary process flow diagram illustrated for client/server-based architecture 550, client 552 may begin by sending a spin request (558) to the server 554, e.g., to indicate to the server that the player is about to play another round of the current game. As described above, server 554 may then randomly determine an outcome for the current round of gameplay. If necessary, the server 554 may then request (560) and receive confirmation of (564) the player's credit balance from the external PAM 556. The outcome for the current round of gameplay and the updated balance may be returned to the client device (562), so that the UI of the client device may be updated with the results of the current round of gameplay. Next, the client device 552 may send a clear recovery request (566) to the server 554, indicating that the current round of gameplay is completed and that it is safe to discard the recovery data for the current round of gameplay. Once the client has received a recovery cleared indication (568) from the server 554, the client device may proceed with requesting the initiation of the next spin (570) from the server 554, thus beginning the next round of gameplay.
As mentioned above, in some client/server-based architecture embodiments, the spin requests may be received and processed asynchronously, i.e., without waiting for the PAM to confirm the credit balance update at 564 (instead relying on the server 554 itself to maintain an accurate credit balance for the player's current gameplay session). Note that there may be some exceptions to the ability to process spin requests asynchronously, such as the processing of a jackpot winning spin. In some client/server-based architecture embodiments, the recovery data for the current round of gameplay may be discarded in response to the server either: (a) receiving a clear recovery data request from the gaming client; or (b) receiving a new spin request from the client gameplay session.

According to some embodiments, at 708, the hosted gaming platform may optionally be configured to discard recovery data for the current round of the first gameplay session in response to receiving a second spin request from the first gameplay session. By holding the recovery data for a current round of gameplay in memory at the hosted gaming platform, if a round of game play is exited by the player in an incomplete state for any reason then, upon returning to the client gaming application, the remainder of the round of gameplay may be “landed” and displayed to the player in the normal fashion, i.e., rather than the player returning to a completed round of gameplay that they were unable to see “land” on the reel strips in the normal fashion.
Finally, at 710, according to some embodiments, the hosted gaming platform may be configured to: receive a stop spin request during the current round of the first gameplay session, wherein the stop spin request is received before the one or more spin results for the first spin request have been produced (also referred to as a “slam stop” request), and wherein the first reel spin duration of the first gameplay session at the frontend gaming client is configured to be extended at least until the frontend gaming client receives the one or more spin results for the first spin request. According to some embodiments, the client may be further configured to provide a graphical indication that the stop spin request may be requested by the client device (e.g., a change in color, size, shape, positioning, labeling, etc. of the stop spin request UI element)-even though the spin may not actually be able to stop until the necessary results are received from the hosted gaming server.
Numerous embodiments are described in this disclosure and are presented for illustrative purposes only. The described embodiments are not, and are not intended to be, limiting in any sense. The present disclosure is widely applicable to numerous embodiments, as is readily apparent from the disclosure. One of ordinary skill in the art will recognize that the innovations described herein may be practiced with various modifications and alterations, such as structural, logical, software, and electrical modifications. Although particular features of the innovations described herein may be described with reference to one or more particular embodiments and/or drawings, it should be understood that such features are not limited to usage in the one or more particular embodiments or drawings with reference to which they are described, unless expressly specified otherwise.
The present disclosure is neither a literal description of all embodiments nor a listing of features of the innovations described herein that must be present in all embodiments.
The Title (set forth at the beginning of the first page of this disclosure) is not to be taken as limiting in any way as the scope of the disclosed embodiments.
When an ordinal number (such as “first,” “second,” “third” and so on) is used as an adjective before a term, that ordinal number is used (unless expressly specified otherwise) merely to indicate a particular feature, such as to distinguish that particular feature from another feature that is described by the same term or by a similar term. For example, a “first widget” may be so named merely to distinguish it from, e.g., a “second widget.” Thus, the mere usage of the ordinal numbers “first” and “second” before the term “widget” does not indicate any other relationship between the two widgets, and likewise does not indicate any other characteristics of either or both widgets. For example, the mere usage of the ordinal numbers “first” and “second” before the term “widget”” (1) does not indicate that either widget comes before or after any other in order or location; (2) does not indicate that either widget occurs or acts before or after any other in time; and (3) does not indicate that either widget ranks above or below any other, as in importance or quality. In addition, the mere usage of ordinal numbers does not define a numerical limit to the features identified with the ordinal numbers. For example, the mere usage of the ordinal numbers “first” and “second” before the term “widget” does not indicate that there must be no more than two widgets.
When introducing elements of aspects of the present disclosure or embodiments thereof, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements. The terms “comprising,” including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.
When a single device, component, structure, or article is described herein, more than one device, component, structure or article (whether or not they cooperate) may alternatively be used in place of the single device, component or article that is described. Accordingly, the functionality that is described as being possessed by a device may alternatively be possessed by more than one device, component or article (whether or not they cooperate).
Similarly, where more than one device, component, structure, or article is described herein (whether or not they cooperate), a single device, component, structure, or article may alternatively be used in place of the more than one device, component, structure, or article that is described. For example, a plurality of computer-based devices may be substituted with a single computer-based device. Accordingly, the various functionality that is described as being possessed by more than one device, component, structure, or article may alternatively be possessed by a single device, component, structure, or article.
The functionality and/or the features of a single device that is described may be alternatively embodied by one or more other devices that are described but are not explicitly described as having such functionality and/or features. Thus, other embodiments need not include the described device itself, but rather can include the one or more other devices which would, in those other embodiments, have such functionality/features.
Further, the systems and methods described herein are not limited to the specific embodiments described herein but, rather, operations of the methods and/or components of the system and/or apparatus may be utilized independently and separately from other operations and/or components described herein. Further, the described operations and/or components may also be defined in, or used in combination with, other systems, methods, and/or apparatus, and are not limited to practice with only the systems, methods, and storage media as described herein.
Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. On the contrary, such devices need only transmit to each other as necessary or desirable, and may actually refrain from exchanging data most of the time. For example, a machine in communication with another machine via the Internet may not transmit data to the other machine for weeks at a time. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more intermediaries.
A description of an embodiment with several components or features does not imply that all or even any of such components and/or features are required. On the contrary, a variety of optional components are described to illustrate the wide variety of possible embodiments of the innovations described herein. Unless otherwise specified explicitly, no component and/or feature is essential or required.
Further, although process steps, algorithms or the like may be described in a sequential order, such processes may be configured to work in different orders. In other words, any sequence or order of steps that may be explicitly described does not necessarily indicate a requirement that the steps be performed in that order. The steps of processes described herein may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to the innovations described herein, and does not imply that the illustrated process is preferred.
Although a process may be described as including a plurality of steps, that does not indicate that all or even any of the steps are essential or required. Various other embodiments within the scope of the present disclosure include other processes that omit some or all of the described steps. Unless otherwise specified explicitly, no step is essential or required.
Although a product may be described as including a plurality of components, aspects, qualities, characteristics and/or features, that does not indicate that all of the plurality are essential or required. Various other embodiments within the scope of the present disclosure include other products that omit some or all of the described plurality.
An enumerated list of items (which may or may not be numbered) does not imply that any or all of the items are mutually exclusive, unless expressly specified otherwise. Likewise, an enumerated list of items (which may or may not be numbered) does not imply that any or all of the items are comprehensive of any category, unless expressly specified otherwise. For example, the enumerated list “a computer, a laptop, a PDA” does not imply that any or all of the three items of that list are mutually exclusive and does not imply that any or all of the three items of that list are comprehensive of any category.
Headings of sections provided in this disclosure are for convenience only, and are not to be taken as limiting the disclosure in any way.
For the sake of presentation, the detailed description uses terms like “determine” and “select” to describe computer operations in a computer system. These terms denote operations performed by a computer, and should not be confused with acts performed by a human being. The actual computer operations corresponding to these terms vary depending on implementation. For example, “determining” something can be performed in a variety of manners, and therefore the term “determining” (and like terms) can indicate calculating, computing, deriving, looking up (e.g., in a table, database or data structure), ascertaining, recognizing, and the like.
As used herein, the term “send” denotes any way of conveying information from one component to another component, and the term “receive” denotes any way of getting information at one component from another component. The two components can be part of the same computer system or different computer systems. The information can be passed by value (e.g., as a parameter of a message or function call) or passed by reference (e.g., in a buffer). Depending on context, the information can be communicated directly between the two components or be conveyed through one or more intermediate components. As used herein, the term “connected” denotes an operable communication link between two components, which can be part of the same computer system or different computer systems. The operable communication link can be a wired or wireless network connection, which can be direct or pass through one or more intermediate components (e.g., of a network). Communication among computers and devices may be encrypted to insure privacy and prevent fraud in any of a variety of ways well known in the art.
It will be readily apparent that the various methods and algorithms described herein may be implemented by, e.g., appropriately programmed general-purpose computers and computing devices. Typically a processor (e.g., one or more microprocessors) will receive instructions from a memory or like device, and execute those instructions, thereby performing one or more processes defined by those instructions. Further, programs that implement such methods and algorithms may be stored and transmitted using a variety of media (e.g., computer readable media) in a number of manners. In some embodiments, hard-wired circuitry or custom hardware may be used in place of, or in combination with, software instructions for implementation of the processes of various embodiments. Thus, embodiments are not limited to any specific combination of hardware and software. Accordingly, a description of a process likewise describes at least one apparatus for performing the process, and likewise describes at least one computer-readable medium for performing the process. The apparatus that performs the process can include components and devices (e.g., a processor, input and output devices) appropriate to perform the process. A computer-readable medium can store program elements appropriate to perform the method.
The term “computer-readable medium” refers to any non-transitory storage or memory that may store computer-executable instructions or other data in a computer system and be read by a processor in the computer system. A computer-readable medium may take many forms, including but not limited to non-volatile storage or memory (such as optical or magnetic disk media, a solid-state drive, a flash drive, PROM, EPROM, and other persistent memory) and volatile memory (such as DRAM). The term “computer-readable media” excludes signals, waves, and wave forms or other intangible or transitory media that may nevertheless be readable by a computer.
The present disclosure provides, to one of ordinary skill in the art, an enabling description of several embodiments and/or innovations. Some of these embodiments and/or innovations may not be claimed in the present application, but they may nevertheless be claimed in one or more continuing applications that claim the benefit of priority of the present application. Applicants may file additional applications to pursue patents for subject matter that has been disclosed and enabled but not claimed in the present application.
The foregoing description discloses only exemplary embodiments of the present disclosure. Modifications of the above disclosed apparatus and methods which fall within the scope of the present disclosure will be readily apparent to those of ordinary skill in the art. For example, although the examples discussed above are illustrated for a gaming market, embodiments of the present disclosure can be implemented for other markets. The gaming system environment of the examples is not intended to suggest any limitation as to the scope of use or functionality of any aspect of the disclosure.
In view of the many possible embodiments to which the principles of the disclosed invention may be applied, it should be recognized that the illustrated embodiments are only preferred examples of the invention and should not be taken as limiting the scope of the invention. Rather, the scope of the invention is defined by the following claims. We therefore claim as our invention all that comes within the scope and spirit of these claims.
While the disclosure has been described with respect to the figures, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the disclosure. Any variation and derivation from the above description and figures are included in the scope of the present disclosure as defined by the claims.
