STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not applicable.

BACKGROUND

This disclosure relates generally to the field of wager games and more particularly to methods and apparatus that facilitate the use of “nudge” features in reel-type 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, with 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 “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.

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, generates a random 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 “nudge” feature into such video slot games. In a video slot game with a nudge feature, once the reels of the game come to rest (i.e. stop spinning), visible symbols will move onto the centre pay line from just above it or below it, adding to the suspense of the game. Alternatively, the nudge feature may form part of a bonus game which, when triggered, provides a player with a predetermined number of nudges to use, allowing the player to move any of the reels upwards (or downwards) one position at a time in an attempt to give rise to winning pay line symbol combinations or bonus-triggering combinations.

It is desirable to adapt such nudge features in novel ways to further enhance the entertainment value and suspense of video slot games.

DETAILED DESCRIPTION
I. Introduction

Reel-type games are disclosed which provide a player with nudge-type functionality, thereby heightening anticipation and increasing excitement of the game. This may be achieved by providing a triggering mechanism for nudging a reel (or reels) if it is determined that, by doing so, a winning payout and/or winning event will result. The triggering mechanism may be implemented via computer-readable program instructions executable by one or more processing units, such as a processing unit within a machine that displays the reel(s) and/or a processing unit within a gaming server that provides the machine with data for displaying the reel(s).

The games of this disclosure are typically played on a machine which is configured to play a reel-type game. For purposes of this description, a reel-type game may be played for a wager (e.g., a reel-type wager game) or played without a wager (e.g., a reel-type non-wager game played for amusements purposes). The reel-type games of this disclosure, regardless of whether being played for wager or without a wager, may feature one or more scatter symbols in addition to a plurality of regular reel-type game symbols that do not comprise a scatter symbol (i.e., a non-scatter symbol).

Scatter symbols may be displayed on a pay line defined for a reel-display area. However, unlike regular reel-type symbols in a video slot game with a reel-display area, a scatter symbol is one that does not have to appear on a specific pay line in order to produce a winning result. With scatter symbols, payouts occur as a result of the scatter symbols occurring on the reels within the reel-display area. Furthermore, obtaining a prescribed number of scatter symbols in a reel-type wager game need not only result in a monetary prize but could, alternatively or additionally, trigger a bonus game. The machine includes a display device configured to display two or more reels of a reel-type game, a memory storing software instructions for facilitating a user to play the reel-type game, and a processing unit for executing the software instructions. The scatter symbol may take any form and could for example be the letter “S”, the word “Scatter” or any other symbol.

II. Example Operation

This is best illustrated by example with reference to a sequence of screen shots shown in FIGS. 1-4. These screen shots show a display on a user interface (10) of a game playing machine used for playing a reel-type game. The machine may take the form of and be referred to as a video gaming terminal, a slot machine, a general purpose computer, a personal digital assistant, a cellular telephone, a game playing machine, or another electronic device. The machine includes a memory (not shown but conventional in such machines) for storing software instructions and a processing unit (e.g., CPU or microprocessor) which executes the instructions stored in the machine, which again is conventional. The sequence and organization of the software instructions will be apparent to persons skilled in the art from the description and illustrated examples of operation of the various embodiments of the invention set forth below.

In particular, FIG. 1 is a representation of a five-reel video slot game which is presented on the display (10) of the game playing machine. Symbols (14) are displayed in an array of symbols (14) in M rows and N columns, here M=3 and N=5. Other examples of the quantity of M rows and N columns (e.g., M=3 and N=3 or M=3 and N=4) are also possible.

Each column is in the form of a reel (12A, 12B, 12C, 12D, and 12E), but the gaming machines of this description are not so limited, because in alternative embodiments each row may be arranged in the form of a reel rather than each column. Each reel (12A, 12B, 12C, 12D, and 12E) displays three symbols within a reel-display area (16) after the reels are spun during a turn of the game. The game has up to 243 pay lines, each comprising a unique sequence of array symbols (14), one from each reel (12A, 12B, 12C, 12D, and 12E), and going from left to right across the reel-display area (16). The pay lines in a game of this type are known in the art and the details are not particularly important.

The array of symbols (14) of the video slot game may contain one or more “scatter” symbols represented in FIG. 1 by the “Eye” symbol (22). In one respect, the scatter symbols may be the same size as a regular non-scatter symbol (e.g., a height that equals a height of a row in the array of symbols (14) and a width that equals the width of a column in the array of symbols (14)). In another respect, however, the scatter symbols may have a height greater than the height of a row in the array of symbols 14, with the result that the tips (30) of the scatter symbol (22) overlap into the array positions immediately above and below the array position that contains the scatter symbol (22) itself. The overlapping tips (30) allow a player to become aware when a scatter symbol (22) has narrowly failed to land on the array of symbols (14) visible in the reel-display area (16), in other words, in the scatter symbol landed in an off-reel-display area. This is illustrated in FIG. 2 where the tip (30) of a scatter symbol that has landed just below the reel-display area (16) (i.e. an “off-reel-display scatter symbol”) overlaps into the bottom array position of reel 12E.

Upon completion of a spin of the video slot game, any winning symbol combinations that appear in the reel-display area (16) are paid out according to a pay table associated with the game. Thereafter an automatic nudge feature is invoked if the reel-display area (16) reveals the presence of an off-reel-display scatter symbol and it is determined that the off-reel-display scatter symbol would result in an additional winning symbol combination if it were located within the reel-display area (16). The automatic nudge feature consists of movement of the off-reel-display scatter symbol by one symbol position to bring the off-reel-display scatter symbol within the reel-display area (16), thus completing the additional winning symbol combination, which is then paid out according to the game pay table.

This is illustrated with reference to FIGS. 3 and 4. In this example, the pay table of the game (not shown) includes winning combinations of three, four or five scatter symbols, each with a corresponding payout. In FIG. 3, a spin of the reels has resulted in two scatter symbols (22) in the reel-display area (16), one on each of reels 12A and 12C and an off-reel-display scatter symbol (22), whose tip (30) is visible at the bottom of reel 12E. It is clear that if the off-reel-display scatter symbol (22) were within the reel-display area (16), a winning symbol combination would result. This condition triggers an automatic nudge feature which commences with an animation of the visible tip (30) of the off-reel-display scatter symbol (22) on reel 12E, as illustrated in FIG. 3. The animation is followed by an upwards nudge of the off-reel-display scatter symbol on reel 12E (i.e. an upwards movement of the off-reel symbol by one symbol position to bring the off-reel-display scatter symbol (22) on reel 12E into the reel-display area (16)) as shown in FIG. 4. The three scatter symbols (22) now in the reel-display area (16) result in an additional winning symbol combination, which is paid out according to the game pay table. It is anticipated that the automated nudge feature to bring off-reel-display scatter symbols within the reel-display area (16) to realise additional potential winning symbol combinations will sustain player interest in the game and greatly increase its attractiveness to players.

Clearly, numerous variations and permutations are possible to this embodiment without departing from the scope of the invention. For example:

- 1. In the above example, the automatic nudge feature moves an off-reel-display scatter symbol into the reel-display area (16) from the bottom of the reel-display area (16). In an alternative embodiment the automatic nudge feature may move an off-reel-display scatter symbol into the reel-display area (16) from the top of the reel-display area (16). In a further alternative embodiment the automatic nudge feature may move off-reel-display scatter symbols into the reel-display area (16) from both the top and the bottom of the reel-display area (16).
- 2. In the above example, a single off-reel-display scatter symbol (22) of the game may be nudged into the reel-display area (16) after a spin of the reels. In an alternative embodiment, more than one off-reel-display scatter symbol may be nudged simultaneously into the reel-display area (16) after a spin of the reels. In yet another alternative embodiment, more than one off-reel-display scatter symbol may be nudged into the reel-display area (16) after a spin of the reels, one after the other, in succession.
- 3. In an alternative embodiment, the nudge feature may apply to any other symbol (e.g., a regular non-scatter symbol) in the symbol set of the game instead of the scatter symbol. In a further alternative embodiment, the nudge feature may apply to more than one specific symbol in the symbol set of the game. In a yet further embodiment the nudge feature may apply to all symbols in the symbol set of the game.
- 4. In an alternative embodiment, if the nudge feature produces more than one additional winning symbol combination in the reel-display area (16), only one of the additional winning symbol combinations may be paid out (for example, the additional winning symbol combination with the highest payout according to the pay table of the game). Further alternatively, every additional winning symbol combination produced by the nudge feature may result in a corresponding payout.
- 5. In the above example, the nudge feature may only be invoked if appropriate conditions apply pursuant to one or more winning symbol combinations that appear in the reel-display area (16) and are first paid out according to the game pay table. In an alternative embodiment, the nudge feature may be invoked unconditionally if appropriate conditions apply, irrespective of whether or not any winning symbol combinations have previously appeared in the reel-display area (16).
- 6. In accordance with the example embodiments in which the nudge feature is carried out for regular non-scatter symbols, a determination whether to nudge one or more regular non-scatter symbols positioned in the off-reel-display area can include determining whether movement of those one or more regular non-scatter symbols causes a winning combination or a higher-valued winning combination to appear on a pay line within the reel-display area (16).
  - For example, if a given pay line does not currently include a winning combination of symbols, but a determination is made that moving the one or more regular non-scatter symbols onto that pay line would result in that pay line including a winning combination of symbols, then a nudge to move those one or more regular non-scatter symbols is carried out.
  - As another example, if a given pay line includes a winning combination of symbols that pays out an award of 100 credits and a determination is made that moving one or more non-regular symbols onto that pay line would result in that pay line including a winning combination of symbols that would earn an award greater than 100 credits, then a nudge to move those one or more regular non-scatter symbols is carried out. In some embodiments if a determination is made that moving the one or more symbols onto the pay line would result in the pay line displaying a combination of symbols that would earn an award less than the award earned by the combination of symbols currently displayed on that pay line (e.g., 100 credits), then the nudge feature is not carried out for those one or more symbols. Alternatively, those one or more symbols are moved onto the pay line and the second smaller award is paid in addition to the award earned for the first combination of symbols displayed on that pay line.
- 7. In accordance with the example embodiments, paying awards for winning symbol combinations based on a number of scatter symbol(s) appearing in the reel-display area (16) may be carried out in various manners. In a first case, if a sufficient number of scatter symbol(s) appear in the reel-display area (16) to win an award prior to moving an off-reel-display scatter symbol within the reel-display area (16), the machine may pay a first award based on the sufficient number of scatter symbol(s) and, thereafter, the machine pays a second award based on the quantity of scatter symbols within the reel-display area (16) after the off-reel-display scatter symbol(s) is moved into the reel-display area (16).
  - In accordance with the first case, the amount of the second award may equal the difference between (i) an amount that would have been awarded as the first award had the reel-display area (16) displayed the number of scatter symbols that appear in the reel-display area (16) after the off-reel-display scatter-symbol(s) are moved within the reel-display area (16), and (ii) the first award. In a second case, if a sufficient number of scatter symbol(s) appear in the reel-display area (16) to win an award prior to moving an off-reel-display scatter symbol(s) within the reel-display area (16), the machine may pay a single award based on the number of scatter symbols appearing in the reel-display area (16) after the off-reel-display scatter symbol(s) is moved into the reel-display area (16).

III. Game Playing Environments

The game functionality disclosed in this description can be carried out via various arrangements including, but not limited to, a stand-alone gaming machine arrangement, and a system arrangement comprising a gaming machine and gaming server communicatively coupled via a communication network. The features of this disclosure, such as nudging off-reel symbols (e.g., regular non-scatter symbols and/or scatter symbols) onto a reel displayed within a reel-display area, and providing notice of the appearance of a specific off-reel 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 FIGS. 1-4. When an off-reel “scatter symbol” (22) is present on a reel, the software for the game displays a portion (30) of the off-reel-display symbol (22) in the reel-display area (16) of the reel-type game as described above, as shown in the far-right reel (12E) in the example of FIG. 2. The software for the game then automatically nudges the off-reel symbol that appeared, by one symbol position so as to bring the off-reel symbol into the reel-display area (16) if and only if, by doing so, a winning symbol combination will result on a pay line of the game. A person skilled in the art will understand that this format is applicable to games played for wagers and with nudging of regular non-scatter symbols.

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 FIG. 5. A casino (40) includes a plurality of game playing machines (50) (in this example, four reel video slot machines) which are connected to a local area network (60). A player inserts a card having a magnetic strip storing a credit amount into a slot (54) in the machine (50). The card is read and wager amounts are deducted from the value carried by the card. The machine (50) includes a display (52) showing four reels (12W, 12X, 12Y, and 12Z). The display (52) may also include features which are not shown, such as wager controls, which are conventional and not important. A turn of the game is initiated by a turn-initiation device, for example, by pulling on the handle (56) or by pressing a spin button, or in some other fashion.

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 (62) 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 an off-screen scatter symbol (22), the gaming server (62) may include with the datagram containing the results of the spin a data flag (e.g., a data bit) which indicates that the off-reel-display scatter symbol is associated with a particular reel (e.g., reel 12X).

Furthermore, the gaming server (62) may include with the datagram a further data flag (e.g., a data bit) indicating whether a one-position nudge of the off-reel symbol on reel (12X) is to be triggered to move the off-reel-display scatter symbol (22) into the reel-display area (58). Alternatively, the software resident in the terminal (50) may include logic or code which searches the datagram for data indicating that the off-reel-display scatter symbol (22) was returned as a result and whether a nudge is to be triggered, and if it finds such data a tip (30) of the off-reel-display scatter symbol (22) is displayed on the reel in question and a one-position nudge of the off-reel-display scatter symbol (22) is activated. For embodiments that nudge regular non-scatter symbols, the datagram may similarly include data flags indicating whether a one-position nudge of a regular non-scatter type symbol positioned in an off-reel-display area should be moved into the reel-display area (16).

Aspects for this invention are also particularly suited for use in the context of playing of wager games over a computer network. Moreover, many of the elements illustrated in FIG. 5 or the other figures and/or described herein are functional elements that may be implemented as discrete or distributed components or in conjunction with other components, and in any suitable combination and location. Those skilled in the art will appreciate that other arrangements and elements (for example, machines, interfaces, functions, orders, and groupings of functions, etc.) can be used instead. Furthermore, various functions described as being performed by one or more elements can be carried out by a processing unit executing computer-readable program instructions and/or by any combination of hardware, firmware, and software.

Referring to FIG. 6, a gaming system suitable for use in wager games and promotions of this disclosure is indicated generally by reference numeral (100). The gaming system (100) includes a central gaming server (102), and a number of portals (103a, 103b) in the form of portal websites on the World Wide Web of the Internet. In this embodiment, each one of the portal websites is an online casino website hosted on a corresponding casino web server (not shown). For convenience, embodiments of the invention will be described with particular reference to only two such online casino websites (103a, 103b). Other online casino websites may be present, or, alternatively, just one casino website may be present.

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 FIG. 6 as separate logical communication networks (106, 107, 108 and 110). The particular networking topology used and presence of intermediate networks or switching equipment is not important, and may make use of intervening communications network such as the public switched telephone network, cable networks, cellular wireless networks, WiFi, WiMax, etc.

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 display monitor (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 display monitor (105). Further details of the conventional features in these embodiments are known in the art and described in the patent literature, see e.g., U.S. Patent Application Publication No. 2007/0060303, which published on Mar. 15, 2007 from U.S. patent application Ser. No. 10/550,744 filed Sep. 23, 2005.

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. As an example, each computer workstation (104) may include one or more processing units, a display device to display the described reel-type games, a computer-readable data storage device (i.e., a memory device) storing computer-readable program instructions described in this disclosure, and a network interface for interconnecting with a gaming server that provides datagrams including data to carry out the games disclosed herein.

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 game, such as 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. Determining the outcome of spins may, for example, include determining each symbol to be placed in the M (rows)×N (columns) array of symbols (14) and either 2 times N symbols to be associated with off-reel-display symbol positions above and below each column of the reel-display area (16) or 2 times M symbols to be associated with off-reel-display symbol positions to the left and to the right of each row of the reel-display area (16). The server process may comprise executing the computer-readable program instructions disclosed herein as being executed by a gaming server and/or a processing unit of the gaming server.

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. The client process may comprise executing the computer-readable program instructions disclosed herein as being executed by the machine to play a reel-type game and/or a processing unit of that machine. The client process may include executing computer-readable program instruction to cause a display device to display animation of reels spinning within the reel-display area (16).

If the slot reels include an off-reel-display scatter symbol (22) whose tip (30) is visible in the reel-display area (16), a nudge of the reel in which the off-reel-display scatter symbol is triggered to bring the off-reel-display scatter symbol within the reel-display area (16) if, by so doing, a winning symbol combination will result on a pay line of the game. As noted, the instruction to trigger a reel nudge could come from the gaming server (102) in the form of a data flag or data bit in the datagram with the results of the spin, or alternatively the workstation program may detect the presence of the relevant symbol in the datagram and trigger the reel nudge.

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 an off-reel-display scatter symbol (22).

The memory (e.g., data storage device) referred to in this description may comprise a non-transitory computer-readable storage medium readable by a processing unit. The computer-readable storage medium may comprise volatile and/or non-volatile storage components, such as optical, magnetic, organic or other memory or disc storage, which can be integrated in whole or in part with a processing unit.

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).

In accordance with example embodiments disclosed herein, after spinning the reels for a turn of the game, the gaming server (102) and/or the computer workstation (104) may determine whether any of the symbols associated with an off-reel symbol position adjacent to a symbol position within the reel-display area (16), if moved into the reel-display area (16), would result in another or a higher-valued winning combination of symbols to be displayed in the reel-display area (16). If moving some or all of the off-reel-display symbols would not result in another or a higher-valued winning combination being displayed, then no movement of the off-reel-display symbols will occur for that turn of the game, and the gaming server (102) and/or computer workstation (104) will transition to wait for initiation of the next turn of the game.
