This application claims priority benefits under 35 U.S.C. §119 to United Kingdom Patent Application serial no. GB 1200662.3 filed Jan. 16, 2012.
Not applicable.
This disclosure relates generally to the field of wager games and more particularly to methods and apparatus that facilitate the use of “stacked” and “expanding” symbols of a reel-type wager game. The methods are applicable in a variety of game playing formats, for example physical slot machines, electronic video gaming terminals, and computer workstations playing wager games over a computer network.
In reel-type games such as slots, one or more reels are provided, each of which contain a multitude of symbols distributed around the circumference of the reel. When a player places a wager (e.g., by placing a coin in the machine) they are then permitted to spin the reels. Each reel comes to rest, typically with either one of the symbols, or a space in between the symbols, in alignment with a pay line. The player wins according to whether a particular winning symbol or combination of symbols is present on the pay line. In a simple three-reel slot machine game, the pay line is the horizontal line going across the middle of the reels. In other reel-type games, such as an array of 3×5 symbols which all change or “spin” during a turn of play, the “pay line” refers to a particular combination of positions of symbols in the 3×5 array which are used to determine if a winning result was achieved; for example, each of the three rows of five symbols could be a different pay line, making three pay lines in total.
The game of slots can be played on a video gaming terminal with a graphical user interface, e.g., a dedicated gaming machine such as found in a casino. In the case of a video gaming terminal, the user interface displays an image of a set of reels. Animation effects are used to simulate the spinning action. A computer software program, which may be resident in the video gaming terminal, randomly generates a result for a simulated spin of the reels, and the result is presented on the user interface.
Slots games are also played over a computer network, e.g., by a player using a personal computer which has established a connection to a gaming server. In this later situation, the gaming server generates results of play and transmits the results over the computer network to the computer for display.
The popularity of video slot games has increased due to the incorporation of a “wild” symbol into such video slot games. A wild symbol, which is usually the highest-ranking symbol of the game, offers line payouts just like any other symbol and, additionally, substitutes for any other symbol in the game, thereby assisting in making winning results and providing a player with entertainment and additional opportunities to win game prizes.
The wild symbol may be associated with additional properties. In particular, the wild symbol may act as a multiplier, i.e. when the wild symbol forms part of a winning result the corresponding payout in the pay table of the game is multiplied by an applicable multiplier. The multiplier is usually fixed and is given in the pay table. The multiplier may also depend on the number of wild symbols forming part of the winning result.
A stacked wild symbol is one that appears as a contiguous stack of wild symbols on a reel (e.g. three wild symbols appearing as if they were successive symbols around the circumference of the reel), which increases still further the potential of having one or more winning results along one of the pay lines.
An expanding wild symbol is one which visually expands (e.g. by computer-driven animation) to occupy the entire reel display area for a given reel, usually depicted by means of an animated sequence. The effect on a payout is the same as that of a stacked wild symbol that occupies the entire reel display area, but the visual effect of the expanding wild symbol animation is different (for example, a single graphical element may expand to cover the whole reel display, rather than the reel display consisting of a plurality of identical wild symbols).
In all of these prior art scenarios, the appearance of a wild symbol (whether single, stacked or expanding) depends on the results of a single play or spin of the underlying video slot game.
Prior art of interest includes Webb US 2005/0070353; Cuddy et al. US 2005/0075163; Jaffe et al. US 2010/0016071; Berman et al US 2004/0132527; Glavich U.S. Pat. No. 6,955,600 and Naicker et al., US 2009/0111566.
In a first aspect, a machine is disclosed which is configured to enable a player to play a reel-type wager game using the machine. The machine includes a display configured to display two or more reels of a reel-type wager game, a memory storing software instructions for facilitating a user to play the reel-type wager game, and a processor for executing the software instructions. The software instructions include instructions for displaying a result of a spin of such reels in the form of a progress symbol associated with progress towards an award of an expanded or stacked symbol. The progress symbol, which may take the form of a WILD symbol or alternatively one of the other symbols in the symbol set for the reels, causes an activation of an accumulation indicator provided on the display. The accumulation indicator, and preferably a set or cluster of such indicators, provides a display of the progress towards meeting a trigger condition for the award of the expanded or stacked symbol in the respective reel over multiple spins of the reel-type game. The expanded or stacked symbol can also take the form of a WILD symbol.
In another aspect, a gaming server is disclosed communicating with a machine having a display enabling a player to play a reel-type game having two or more reels over a computer network such as the Internet or a local area network, for example in a casino environment. The gaming server includes a processing unit randomly generating results of a spin of each of a plurality of reels in the reel-type game for the machine and transmitting such results to the machine as a datagram over the computer network. The datagram generated by the gaming server includes a data element, e.g., flag or bit, or alternatively data associated with symbols, indicating that one of the results of a spin of such plurality of reels is in the form of a progress symbol associated with progress towards an award of an expanded or stacked symbol. The datagram causes an activation of an accumulation indicator on the machine display providing a display of the progress towards meeting a trigger condition for the award of the expanded or stacked symbol over multiple spins of the reel-type game.
In yet another aspect, a method of playing a reel-type game using a machine having a display is provided. The method includes the steps of providing on the display a plurality of reels, displaying a result of a spin of such reels in the form of a progress symbol associated with progress towards an award of an expanded or stacked symbol, and the progress symbol causing an activation of an accumulation indicator provided on the display providing a display of the progress towards meeting a trigger condition for the award of the expanded or stacked symbol in the respective reel over multiple spins of the reel-type game.
Reel-type games are disclosed which provide a player with a visible indication of progress being made towards the appearance of a stacked or expanding symbol on a reel, thereby heightening anticipation and increasing excitement of the game. This is achieved by providing a trigger mechanism for appearance of the stacked or expanding symbol in which the required trigger condition can be achieved (i.e. accumulated or collected) over multiple turns or spins of the video slot game, and by providing a display of the progress towards meeting the trigger condition to the player directly on the display of the game.
The games of this disclosure are typically played on a machine which is configured to play a reel-type wager game featuring a wild symbol. The machine includes a display configured to display two or more reels of a reel-type wager game, a memory storing software instructions for facilitating a user to play the reel-type wager game, and a processor for executing the software instructions. The software features instructions for displaying on the display sets of accumulation indicators associated with each of the two or more reels. An accumulation indicator of a set, which may take the form of an icon or graphical device of any sort, becomes active when the corresponding reel first displays a progress (e.g., wild) symbol during a playing session. The progress symbol may take any form and could for example be the letter “W”, the word “Wild”, a Bengal Tiger or fanciful symbol, or any other symbol that is associated with the functionality of progress towards the trigger condition. During the playing session the accumulation indicators register each appearance of a progress symbol on the corresponding reel.
This is best illustrated by example with reference to a sequence of screen shots shown in
In particular,
The purpose of the accumulation indicators (16) is to indicate the occurrence of progress (e.g., wild) symbols on the various reels of the game. The accumulation indicators (16) of
The set of symbols (14) of the video slot game contains a “wild” symbol represented in
In theory, the accumulation of wild symbols could be preserved as long as the player continues to play in one continuous session. It is also possible to “bank” the accumulation should the player quit playing and resume playing later, as will be described in further detail later on.
Turning now to
The expanded wild symbol (24) on reel 12B does not persist beyond the spin of the video slot game in which it was triggered. On each successive spin of the video slot game after the expanding wild symbol was triggered, one of the accumulation indicators (16) of cluster 20B deactivates unconditionally until all four accumulation indicators (16) are inactive, whereupon accumulation of wild symbols can resume, as described above. It is important to observe that activation and deactivation of accumulation indicators (16) corresponding to each reel (20) occurs independently to that on the other reels of the game.
As illustrated in
After the accumulation threshold for any particular reel has been satisfied the last wild symbol to have appeared typically triggers an expanding wild symbol on that reel. Once any resulting winning pay line results have been paid out, the expanding wild symbol (24) on the reel clears and the accumulation indicators (16) associated with the reel become inactive progressively over successive spins of the reels. The player then has to again accumulate the required number of wild symbols on the particular reel as before, and the player's progress towards meeting the accumulation threshold is presented using the accumulation indicators (16) in the manner described above.
In the above embodiment, the essence of the triggering mechanism is that active accumulator indicators (16) are accumulated in any reel over time as game play progresses and the expanding wild symbol is triggered when the total number of active accumulator indicators (16) for the reel meets a threshold, four in this example. It is anticipated that player interest in the video slot game will be sustained, particularly in circumstances where a player has accumulated a substantial proportion of the active accumulation indicators required to trigger an expanding wild symbol on one or more reels.
Clearly, numerous variations and permutations are possible to this embodiment without departing from the scope of the invention. For example:
As noted previously, the feature of this disclosure of providing notice of progress being made towards the appearance of a stacked or expanding symbol on a reel of a reel-type game can be implemented in a variety of game playing formats. Several representative examples of these formats will be described in this section.
In one format, a personal computer is loaded with game playing software which includes a reel-type game. The game can be played solely for amusement, in which case the computer is typically not interacting with any external resource which logs wagers, determines and communicates results, or adjusts a player's credit account. The game software presents the reels such as shown in
In another format, the game may be played in a video gaming terminal, such as found in a land or ship-borne casino. One example of this embodiment is shown in
In this example, the results of play are generated by a gaming server (62) using a random number generator (or other process to generate a set of reel symbols randomly). The gaming server communicates the results of play to the video gaming terminal (50) over the network (60) as a packet or datagram containing data indicating which symbols are to be displayed on the reels (12). The datagram is processed by software resident on the video gaming terminal (50) and presented on the display (52) in known fashion. When the server's randomly generated results include the wild symbol (22), the server includes with the datagram containing the results of the spin a flag or bit which indicates that an accumulation indicator (16) of the cluster associated with the reel in question is to become active, since one of the resulting symbols for reel (12B) is the star symbol (22). Alternatively, the software resident in the terminal (50) may include logic or code which searches the datagram for data indicating that the star symbol was returned as a result, and if it finds such data an accumulation indicator (16) of the cluster for the associated reel (12B) is activated.
In this example, suppose the player accumulated a single active accumulation indicator (16) on reel 12B and then decided to play poker at a table in the casino (40), or some other wager game on a different machine (50). The player's accumulation of active accumulation indicators (16) is stored in the gaming server (62) or, alternatively, locally on the player's magnetic card. The player ejects their card from the slot (54) and then proceeds to play wager games elsewhere in the casino. At a later time, they may return to a machine (50) (which need not be the same machine they previously played at) and insert their card. The card includes a unique code such as a card number which is correlated at the server (62) with the stored results when the player previously exited the game. The display of the reels reverts to the display of the accumulated active accumulation indicators (16) that was present when the player previously exited the game on the previous machine (50). In this example, the single accumulation indicator (16) associated with cluster (20B) corresponding to reel 12B is active and the player continues accumulating wild symbols where they left off. In one variation, the accumulation of active accumulation indicators (16) is not carried over and when they exit the play on the machine (50) any accumulated active accumulation indicators (16) are lost.
Aspects for this invention are also particularly suited for use in the context of playing of wager games over a computer network, including a local area network for example in a physical casino environment or over a wide area network, such as the Internet.
Referring to
Each one of the online casino websites (103a, 103b) is accessible by a would-be player (not shown) through a player gaming workstation (104) in the form of an Internet-enabled computer workstation (e.g., general purpose computer) having a display monitor (105) and an associated pointing device (105a) such as a mouse or, alternatively, a touchpad. In this embodiment, online casino website (103a) is shown as having one computer workstation (104) logically connected thereto, whereas casino website (103b) is shown as being logically connected to two computer workstations (104). It will be appreciated by those skilled in the art that such online casino websites (103a, 103b) can be logically connected to any desired number of such computer workstations (104) simultaneously, which number is physically limited only by considerations of processing power and Internet access bandwidth.
The gaming server (102), the online casino web servers (not shown) corresponding to the online casino websites (103a, 103b), and the computer workstations (104) are capable of communicating with each other by means of an open communication network that is, in this embodiment, the Internet. The Internet is represented in
Each online casino operates an account facility (114a and 114b, respectively) with a credit account corresponding to each player who participates in a game offered by the online casino. In the illustrated embodiment, therefore, the credit account facility (114a) has one player credit account associated with it, while credit account facility (114b) has two associated, but separate, player credit accounts.
A stored workstation program (not shown) is resident in the client computer workstation (104) which enables a participating player to browse a casino website and to interact with the gaming server (102) to play wager games such as slots, poker, Black Jack, Roulette and other games. The stored workstation program includes display tools for displaying on the user interface display (105): gaming symbols (e.g., slot machine reels, cards, Roulette wheels, etc.), gaming controls by which the player can place wagers, spin the reels, etc., and the results of play. The stored workstation program also includes gaming logic for facilitating the execution of a turn of a game, and communications facilities for communicating player actions using the user interface to the central gaming server, and receiving datagrams from the gaming server containing results of play. The data representing results of play is translated to graphical symbols which are presented on the user interface display (105). Further details of the conventional features are known in the art and described in the patent literature, see e.g., U.S. application Ser. No. 10/550,744 filed Sep. 23, 2005, published as US 2007/0060303.
Each computer workstation (104) may take the form of a conventional personal computer operating under a Windows XP, ME, 2000 or other operating system, which is well known and commercially available from Microsoft Corporation of Redmond, Wash., or other operating system such as provided by Apple Computer or a Linux operating system. The gaming workstation may also take the form of a portable computing device such as personal digital assistant or cellular telephone. The gaming workstation may also take the form of an electronic gaming terminal.
The gaming server (102) operates under control of a server-stored program (not shown) that co-operates with the stored workstation program in order to enable a player at the computer workstation (104) to play a wager game. The gaming server (102) operates, for example, under the Windows NT operating system.
The stored workstation program or application (not shown) and the corresponding stored server program will be referred to, for convenience, as a client process and a server process, respectively. The server process generates one or more random events that determine the outcome of turns of the game, such as determining the outcome of spins of the slot machine reels in the various slots games of the participating players. The client process of any particular computer workstation (104) obtains the result of the random events from the gaming server (102) along the communication network (108) and displays the outcome of the game on the display monitor (105) of the workstation in an intelligible manner, by causing the player's set of slots reels to spin and to come to rest at a position corresponding to the outcome. If a slot machine reel includes a progress symbol associated with an award of progress towards an expanded or stacked symbol, such as the star symbol of
The gaming server (102) thus generates results of spins of the reels for the workstations (104) and sends datagrams to the workstations indicating such results. In one possible embodiment, to generate the results of a spin of the reels, the gaming server (102) includes a memory (not shown, but conventional) storing data representing potential results for each of the reels. The gaming server uses a random process (e.g., random number generator) to select one of the results from memory. One of the results stored in the gaming server memory is data representing a result in the form of a symbol which is associated with progress towards an award of a stacked or expanded symbol, e.g., the star symbol of
The gaming server can also “bank” the progress made towards an expanded or stacked symbol in the event that a player ceases playing the reel-type game, e.g., logs out of the casino or elects to play other games such as poker. The gaming server is further provided with a memory storing data (e.g., flags or bits) indicating, for each reel of the video slot game, whether any progress has been made towards an expanded or stacked symbol. The gaming server stores such data in the memory after the workstation has ceased play of the game. Should the player return to playing the reel-type game, the gaming server (102) consults the memory and returns a datagram to the player's workstation which includes such data. The player's workstation display then shows the accumulated or “banked” progress towards an expanded or stacked symbol on each reel of the video slot game (e.g., activation of the respective accumulation indicators that were previously activated) and starts play where they previously left off.
In order to play the games from any particular computer workstation (104), the client process (not shown) must first be downloaded to that computer workstation from the gaming server (102) or, alternatively, from a separate web server (not shown), and then installed on the workstation.
In use, a player wishing to participate in a wager game uses a computer workstation (104) to access an online casino website (103a, 103b) of his choice. When the player navigates using a Web browser to a home page of a casino, a promotional message may be displayed (described below). The player is presented with an icon on the GUI on his computer workstation (104), which the player can activate in order to download the client process and register with the casino operator. Following these tasks, the player may request to play games provided on the casino website by clicking on an appropriate icon or taking other similar action.
The online casino websites (103a, 103b) may be provisioned as a virtual slots room where slots is the only game available to would-be players, rather than one where a variety of different games are offered to a player.
It will be noted again that a system implementing the methods of this invention need not include two (or more) separate casino websites (103a, 103b), and that only one website (103) may be linked to the gaming server (102).
