DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1 of the drawings, there is shown a gaming system 10 including multiple player operable gaming machines 12, each of which in this example is arranged to implement a probabilistic wagering game of the type wherein a player wagers a bet amount, and a game outcome is determined in a probabilistic way. With some such probabilistic games, several symbols from a set of symbols are randomly displayed, and a game outcome is determined on the basis of the displayed symbols.
The gaming machines 12 communicate with a notification system 14 through a local network 16, the notification system 14 being arranged to gather status information from the gaming machines 12 indicative of whether the gaming machines are implementing a game, and to communicate the status information to the gaming machines 12 on request.
A game may be implemented by the gaming system in various ways.
In a first implementation, a stand alone gaming machine is provided wherein all or most components required for implementing the game are present in a player operable gaming machine.
In a second implementation, a distributed architecture is provided wherein some of the components required for implementing the game are present in a player operable gaming machine and some of the components required for implementing the base game are located remotely relative to the gaming machine.
For example, a “thick client” arrangement may be used wherein part of the game is executed on a gaming machine 12 and part of the game is executed by a gaming server, or a “thin client” arrangement may be used wherein most of the game is executed remotely by the gaming server and a gaming machine 12 is used only to display audible and/or visible gaming information to the player and receive gaming inputs from the player.
However, it will be understood that other arrangements are envisaged. For example, an architecture may be provided wherein the respective functions of the gaming machine 12 and the gaming server are selectively modifiable. For example, the gaming system may operate in stand alone gaming machine mode, “thick client” mode or “thin client” mode depending on the game being played, operating conditions, and so on. Other variations will be apparent to persons skilled in the art.
Operative components of the notification system 14 are shown in FIG. 1.
The notification system 14 includes a game status receiver 18 arranged to receive status information from each of the gaming machines 12 associated with the gaming system 12. The status information from each gaming machine 12 includes information indicative of whether the gaming machine 12 is implementing a game (occupied) or is available for game play (vacant), and information indicative of the game, the denomination associated with the game such as the minimum bet amount per line, and any other game related information.
The notification system 14 also includes a game request receiver 20 arranged to receive game request information from the gaming machines 12, the game request information including information indicative of the game desired to be played by a player and/or a particular gaming machine desired to be played by a player, and of the current gaming machine being played by the player.
The notification system 14 also includes a layout server 22 arranged to generate layout information indicative of the locations of at least some of the gaming machines 12 associated with a gaming venue, of the types of games implementable by the gaming machines 12, and of the availability of the gaming machines 12 for game play using the status information received at the game status receiver 18 from the gaining machines 12. The layout server 22 also communicates the layout information to the gaming machines through the network 16, for example when requested by a gaming machine 12 in response to player input. The layout information is used by the gaming machines 12 to generate a representation on a display of a gaming machine of a venue layout showing the locations of the gaming machines associated with the gaming system 10 in relation to the venue and relative to each other, the games implemented by the gaining machines, the denomination(s) appropriate for the gaming machines 12, and whether the gaming machine(s) are available to be played by a prospective player.
As an alternative to serving the layout information to the gaming machines for display at the gaming machines, the gaming system may be arranged so as to display the layout information at a display location separate to the gaming machines.
As an alternative to receiving game requests from gaming machines, the gaming system may be arranged to receive game requests from other devices, such as from a game request facility at the notification system 14 or at a kiosk located at the gaming venue, or from a communications enable mobile device such as a mobile phone associated with a player.
Using controls on a gaming machine 12 which may be buttons or a touch screen, a player is able to select a game which is currently unavailable and which is desired to be played by the player, and in this example the player is also able to select a specific gaming machine which is desired to be played. After selection of a game to be played, or a gaming machine to be played, a game request communication is sent from the gaming machine to the notification system 14 through the network 16. The game request communication is received by a game request receiver 20 which communicates with a notification controller 24, and using information provided by the game status receiver 18 the notification controller 24 determines when the requested game or gaming machine 12 becomes available. When the requested game or gaming machine 12 becomes available, the notification controller 24 sends a machine free notification to the relevant gaming machine associated with the game request, and based on receipt of the machine free notification the gaming machine displays an available message to the player to indicate that the desired game and/or gaming machine is now available.
As an alternative to sending a machine free notification to the relevant gaining machine associated with the game request, the machine free notification may be used at the notification system 14, sent to a dedicated player notification device located at the gaming venue, or sent to a mobile communications device such as a mobile phone associated with the player.
Irrespective of the destination of the machine free notification, a visible indication is generated to indicate to the requesting player that the requested game and/or gaming machine is available.
The gaming system 10 may be arranged such that after receipt of the machine free notification, the player has a predefined period of time in which to commence game play at the requested gaming machine 12, otherwise the gaming machine 12 becomes available to all prospective players.
In order to ensure that the requested game and/or requested gaming machine is reserved for use only by the requesting player, the player may be provided with an identifier which may be in the form of an alphanumeric code or may be in the form of a printed ticket, with the desired gaming machine being provided with the facility to accept the identifier, for example by providing the gaming machine with a keypad or ticket reader, and to validate the identifier in order to verify the validity of the prospective player. As a further alternative, the gaming machines may be arranged to receive data storage cards which are capable of storing identifiers together with other personal and/or game play related information specific to the players. On receipt of a valid identifier at the gaming machine within the allowed time period, the game is implemented.
In this example the layout server 22, the notification controller 24, the game request receiver 20, and the game status receiver 18 are implemented using a processor 26 and associated software (not shown), although it will be understood that other implementations are envisaged.
A gaming machine 40 of stand alone type is illustrated in more detail in FIG. 2. The gaming machine 40 includes a console 42 having a display 44 on which is displayed representations of a game 46 that can be played by a player. A mid-trim 50 of the gaming machine 40 houses a bank of buttons 52 for enabling a player to interact with the gaming machine during game play, including enabling the player to select the bet amount. The mid-trim 50 also houses a credit input mechanism 54 which in this example includes a coin input chute 54A and a bill collector 54B. A reading device may also be provided for the purpose of reading a player tracking device, for example as part of a loyalty program. The player tracking device may be in the form of a card, flash drive or any other portable storage medium capable of being read by the reading device.
A top box 56 may carry artwork 58, including for example pay tables and details of bonus awards and other information or images relating to the game. Further artwork and/or information may be provided on a front panel 59 of the console 52. A coin tray 60 is mounted beneath the front panel 59 for dispensing cash payouts from the gaining machine 40.
The display 44 is in the form of a video display unit, particularly a cathode ray tube screen device. Alternatively, the display 44 may be a liquid crystal display, plasma screen, any other suitable video display unit. The top box 56 and/or the front panel 59 may also include a display, for example a video display unit, which may be of the same type as the display 44, or of a different type.
The display 44 may include a touch screen and the buttons 52 and/or the touch screen may be arranged such that a player is able to use the buttons 52 and/or the touch screen to cause the gaming machine layout to be shown on the display 44 and to select a game and/or a gaming machine which is desired to be played.

The displays 204 may be used to display representations associated with game play on the gaming machines 202, and/or used to display other representations, for example promotional or informational material.
In a thick client embodiment, a game server 205 implements part of the game played by a player using a gaming machine 202 and the gaming machine 202 implements part of the game. With this embodiment, as both the game server 205 and the gaming machine 202 implement part of the game, they collectively provide a game controller. A database management server 206 may manage storage of game programs and associated data for downloading or access by the gaming devices 202 in a database 206A. Typically, if the gaming system enables players to participate in a Jackpot game, a Jackpot server 207 will be provided to monitor and carry out the Jackpot game.
In a variation of the above thick client embodiment, the gaming machine 202 may implement the game, with the game server 205 functioning merely to serve data indicative of a game to the gaming machine 202 for implementation.
With this implementation, a data signal containing a computer program usable by the client terminal to implement the gaming system may be transferred from the game server to the client terminal, for example in response to a request by the client terminal.
In a thin client embodiment, the game server 205 implements most or all of the game played by a player using a gaming machine 202 and the gaming machine 202 essentially provides only the player interface. With this embodiment, the game server 205 provides the game controller. The gaming machine will receive player instructions, and pass the instructions to the game server which will process them and return game play outcomes to the gaming machine for display. In a thin client embodiment, the gaining machines could be computer terminals, e.g. PCs running software that provides a player interface operable using standard computer input and output components.
Servers are also typically provided to assist in the administration of the gaming system 200, including for example a gaming floor management server 208 and a licensing server 209 to monitor the use of licenses relating to particular games.

The gaming system 200 may communicate with other gaming systems, other local networks such as a corporate network, and/or a wide area network such as the Internet, for example through a firewall 211.
A loyalty program server 212 may also be provided.
Persons skilled in the art will appreciate that in accordance with known techniques, functionality at the server side of the network may be distributed over a plurality of different computers. For example, elements may be run as a single “engine” on one server or a separate server may be provided. For example, the game server 205 could run a random number generator engine. Alternatively, a separate random number generator server could be provided.
Operation of an exemplary gaming system 10 will now be described with reference to the flow diagram 120 shown in FIG. 6 and the gaming machine layout shown in FIG. 7. The flow diagram 120 illustrates steps 122 to 146 carried out in a method of managing usage of gaming machines in accordance with an embodiment of the invention.
In the present example shown in FIG. 1, three gaming machines 12 are shown associated with the local network 16, although it will be understood that in practice more than three gaming machines 12 would typically be present.
Each gaming machine 12 implements a probabilistic game of the type wherein a player is able to place a bet and obtain a prize when the game results correspond to a winning outcome. In this example, a first gaming machine 12a is configured to implement a first game Queen of the Nile with a denomination of $1, a second gaming machine 12b is arranged to implement a game Black Panther with a denomination $1, and a third gaining machine 12c is arranged to implement a game Spring Carnival with a denomination 50c. 
In this example, each of the games implemented by the gaming machines 12 is a spinning reel game of the type wherein several symbols from a set of symbols are randomly displayed, and a game outcome is determined on the basis of the displayed symbols. With such probabilistic games, the set of symbols may include standard symbols and function symbols, and the game outcome is determined on the basis of the displayed standard symbols and the function associated with any displayed function symbol. For example, standard symbols may resemble fruit such as apples, pears and bananas with a win outcome being determined when a predetermined number of the same fruit appear on a display in the same line, scattered, and so on. The function associated with a function symbol may be for example a wild function wherein display of the function symbol is treated during consideration of the game outcome as any of the standard symbols. A function symbol may be represented as the word “WILD”, a star, or by any other suitable word or symbol. Other functions are also envisaged such as scatter functions, multiplier functions, repeat win functions, jackpot functions and feature commencement functions.
Using an appropriate button or using a touch screen on a gaming machine, a player is able to cause a layout 150 of gaming machines in the gaming venue to be displayed on the gaming machine display. An example gaining machine layout 150 is shown in FIG. 7.
The gaming machine layout 150 includes regions 152 associated with gaming machines, the locations of the regions relative to each other being representative of the locations of the gaming machines 12 relative to each other at the gaming venue. Each region 152 includes a description of the game, the denomination of the game associated with the region, and information indicative of whether the gaming machine is vacant or occupied. The regions may also be arranged so as to provide an additional readily recognizable indication as to whether the associated gaming machines are vacant or occupied, for example by displaying vacant gaming machine regions 152a in a first colour such as green, and displaying occupied gaming machine regions 152b in a second colour such as red, by flashing either the vacant gaming machine regions or the occupied gaming machine regions, or in any other way. In the example shown in FIG. 7, vacant gaming machines are indicated by representing the vacant gaming machine regions 152a with full lines and occupied gaming machines are indicated by representing the vacant gaming machine regions 152b with broken lines.
A player may use the gaming machine layout 150 to determine which gaming machines are vacant. If a desired gaming machine 12 is occupied or all gaming machines implementing a desired game are occupied, the player has the option of reserving a gaming machine by selecting the occupied gaming machine. In this example selection of a gaming machine may occur by touching the gaming machine display at the desired gaming machine region 152.
After selection of an occupied gaming machine, a gaming machine request communication is sent from the gaming machine to the notification system 14 which creates a request record including information indicative of the requesting gaming machine, of the requested gaming machine and an identifier usable to verify the identity of the player when the requested gaining machine becomes free.
The notification system 14 then monitors status information received from the gaming machines at the venue in order to monitor the gaining status of the requested gaining machine. When the requested gaming machine becomes available, a machine free notification is sent from the notification system 14 to the requesting gaming machine 12 and displayed on the requesting gaming machine to indicate to the player that the desired gaming machine is now available. When this occurs, a timer starts which determines an amount of time available for the player to finish the current game being played and commence a game at the requested gaming machine. In order to ensure that only the correct player is able to play the game on the requested gaming machine within the allowed time period, the player may be provided with an identifier, for example printed on a ticket. The identifier is communicated to the requested gaining machine, for example by introducing the ticket into the requested gaming machine within the allowed time period, and if the identifier matches the identifier stored in the respective request record, the requested gaming machine 12 is made available to the player to play a game. If the player does not commence the game at the requested gaming machine within the allowed time period, the reservation ceases and any prospective player is able to play a game on the requested gaming machine.
While the above embodiments are described in relation to a gaming system including a notification system 14 in networked communication with a plurality of gaining machines 12 and arranged to gather status information from the gaming machines, disseminate the information to the gaming machines, and to facilitate reservation of desired gaming machines by players, it will be understood that other variations are possible. For example, as shown in FIG. 8, an alternative gaming system 220 is shown wherein each gaming machine 222 is arranged to communicate directly with other gaming machines 222 through the network 16, for example by providing each gaming machine 222 with a notification system 224 configured carry out functions similar to the functions carried to out by the notification system shown in FIG. 1. In particular, each notification system 224 may be arranged to generate a gaming machine layout 150 based on status information received directly from all other gaming machines, to send gaming machine requests directly to other gaming machines, and to receive notifications of availability directly from requested gaming machines. With this embodiment, the above functions may be carried out by a notification module connected to each gaming machine. The notification module may comprise a player marketing module (PMM) and/or a player tracking module (PTM).
In alternative arrangements using a server based architecture wherein a game is at least partly implemented at a central server, instead of arranging each gaming machine to provide status information indicative of whether the gaming machine is vacant or occupied, the system may be arranged such that the status information is generated by the central server.
Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
