  • It is also possible for the operative components of the gaming machine 60 to be distributed; for example, input/ output devices 82, 84, 86, 88, 90, 92 may be provided remotely from game controller 62.
  • FIG. 5 shows a gaming system 100 in accordance with an alternative embodiment. Gaming system 100 includes a network 102 that may be, for example, an Ethernet network. Gaming machines 104, shown arranged in three banks 106 of two gaming machines 104 in FIG. 5, are connected to the network 102. Gaming machines 104 provide a player operable interface and may be the same as gaming machines 30, 60 shown in FIGS. 2 and 3, or may have simplified functionality depending on the requirements for implementing game play. While banks 106 of two gaming machines are illustrated in FIG. 5, banks of one, three or more gaming machines are also envisaged.
  • One or more displays 108 may also be connected to the network 102. Displays 108 may, for example, be associated with one or more banks 106 of gaming machines. Displays 108 may be used to display representations associated with game play on gaming machines 104, to display other representations, such as promotional or informational material, or both.
  • In a thick client embodiment, game server 110 of gaming system 100 implements part of the game played by a player using a gaming machine 104 and gaming machine 104 implements part of the game. With this embodiment, as both the game server and the gaming machine implement part of the game, they collectively provide a game controller. A database management server 112 may manage storage of game programs and associated data for downloading or access by the gaming devices 104 in a database 112A. Typically, if the gaming system enables players to participate in a Jackpot game, a Jackpot server 114 will be provided to carry out the accounting in respect of the Jackpot game. A loyalty program server 116 may also be provided.
  • In a thin client embodiment, game server 110 implements most or all of the game played by a player using a gaming machine 104 and gaming machine 104 essentially provides only the player interface. With this embodiment, game server 110 provides the game controller. Gaming machine 104 receives player instructions, passes these to game server 110, which then processes them and returns game play outcomes to gaming machine 104 for display. In a thin client embodiment, gaming machines 104 may be computer terminals, such as 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 gaming system 100 including, for example, a gaming floor management server 118, and a licensing server 120 to monitor the use of licences relating to particular games.

  • Gaming system 100 may communicate with other gaming systems, with other local networks such as a corporate network, with a wide area network such as the Internet, for example through a firewall 124, or a combination of these.
  • Persons skilled in the art will appreciate that, in accordance with known techniques, functionality at the server side of gaming system 100 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, game server 110 could run a random generator engine. Alternatively, a separate random number generator server could be provided. Further, persons skilled in the art will appreciate that a plurality of games servers could be provided to run different games or a single game server may run a plurality of different games as required by the terminals.
  • As discussed above, embodiments are provided according to the present invention that are implemented in relation to a spinning reel type game, the gaming systems for implementing these games having a video display 18, 34, 82. The characteristics of displays 18, 34, 82 may differ from one implementation of gaming machine 30, 104 or gaming system 100 to another, and even from one gaming machine 104 to another with gaming system 100. For example, in one gaming machine 30, 104 according to these embodiments, display 18, 34, 82 has a native resolution of 1280×1024. In another gaming machine 30, 104 according to these embodiments, display 18, 34, 82 has a native resolution of 1680×1050. Display 18, 34, 82 with 1280×1024 resolution can be connected with a VGA or DVI connector. As these displays have significantly different aspect ratios, unacceptable horizontal stretching would occur if they were used with the same display resolution, so gaming machines 30, 104 and gaming systems 100 according to these embodiments are configured to detect the resolution of display 18, 34, 82 and adjust display resolution accordingly.
  • However, display 18, 34, 82 comprises two monitors 18A,18B, 34A,34B, 82A,82B. Some existing graphics hardware exhibits severe performance reduction when the vertical resolution of the whole display area (in this example comprising two monitors) exceeds 2048 pixels. Hence, even if one or both of monitors 18A,18B, 34A,34B, 82A, 82 B constituting display 18, 34, 82 have a resolution of 1680×1050, according to the above embodiments the displayed resolution is set to 1680×1024 in both monitors 18A,18B, 34A,34B, 82A,82B. In addition, the display refresh rate is set to 60 Hz for reasons of backward compatibility.
  • FIG. 6 is another schematic view of display 18 and game controller 14 of FIG. 1 (with which game controller 62 of FIG. 3 is comparable), with more detail shown in the game controller 14. As mentioned above, display 18 comprises two monitors, a main monitor 18A and a second monitor 18B (just as display 34 of FIG. 3 comprises main monitor 34A and second monitor 34B and display 82 of FIG. 3 comprises main monitor 82A and second monitor 82B).
  • X11 server 28 of game controller 14 includes X 130, the xrandr utility program 132 and the xrdb utility program 134. Memory 24 includes an X server configuration file 140, a file /var/log/xorg.log 142 and Xresources files 144. Game controller 14 also includes a Display Data Channel (DDC) 150, which provides a digital connection between the monitors of display 18 and X11 server 28 of gaming machine 30; DDC 150 allows display 18 to communicate its specifications to X11 server 28. Support for DDC 150 is built into the kernel of operating system 26 of game controller 14, and is turned on in X server configuration file 140 if it is to be used. If DDC 150 is turned on in X server configuration file 140, X 130 automatically attempts to set the screen resolution and refresh rate to one that is supported by the monitor. This is a problem if the attached monitor has a resolution of, for example, 1680×1050 but—as in these embodiments—the displayed vertical resolution is to be set to 1024 in both monitors 18A,18B. Thus, in order to detect the resolutions supported by monitors 18A,18B, 34A,34B, 82A, 82B and to set them both to have a vertical resolution of 1024, the following steps, illustrated in flow diagram 160 of FIGS. 7A and 7B, are performed according to the present embodiments. It should be noted that, in this example, it is assumed that both monitors 18A,18B, 34A,34B, 82A, 82B in any particular gaming machine are identical, and that they are both either: (i) VGA 1280×1024, or (ii) 1680×1050.
  • Referring to FIG. 7A, at step 162 X11 server 28 is run with DDC 150 enabled. At step 164, xrandr utility program 132 is executed, and—at step 166—prompted by xrandr utility program 132, X11 server 28 queries monitors 18A,18B (via DDC 150) for their supported modelines.
  • At step 168, the modelines supported by monitors 18A,18B are returned to X11 server 28 which, at step 170, writes this information to the file /var/log/xorg.log 142. This modeline data includes the resolutions supported by monitors 18A,18B.
  • At step 172, X11 server 28 is shut down. At step 174, game controller 14 scans xorg.log 142 for the text “VGA connected”, to ascertain whether monitors 18A,18B support VGA (and hence, according to this example, have maximum resolutions of 1280×1024).
  • At step 176, it is determined whether the text “VGA connected” was located in xorg.log 142 (and hence whether monitors 18A,18B support VGA); if so processing continues at step 178, where a display resolution record 146 is created in memory 24 indicating that the resolution that monitors 18A,18B will be set to is 1280×1024, as—according to this embodiment—other resolutions for VGA connected monitors are not supported. Processing then passes to step 186 (see FIG. 7B).
  • If, at step 176, it is determined that the text “VGA connected” was not located in xorg.log 142 and hence that monitors 18A,18B do not support VGA, processing continues at step 180 where game controller 14 scans xorg.log 142 for the text “Modeline “1680×”, that is, the other resolution expected to be found. At step 182, it is determined whether that text was located in xorg.log 142 and, if so, processing passes to step 184 where a display resolution record 146 is created in memory 24 indicating that the resolution that monitors 18A,18B will be set to is 1680×1024. Game controller 14 does not, in this embodiment, support having two monitors with different resolutions so, as discussed above, gaming machines 30, 60, 104 are not provided with monitors 18A,18B of different resolutions; hence, if either monitor 18A,18B supports 1680 horizontal resolution, it can be assumed according got this embodiment that both do, so the displayed resolution is set to 1680×1024. Processing then continues at step 186 (see FIG. 7B).
  • At step 186, X11 server 28 is run with DDC 150 disabled and a modeline corresponding to display resolution record 146 as created at either step 178 or 184.
  • At step 188, xrdb utility program 134 is used to load the Xresources file 144 that corresponds to the display resolution indicated by display resolution record 146. Processing of the steps of this method then ends: the data in this Xresources file 144 is subsequently used by game controller 14 to determine the display resolution.
  • If, at step 182, it is determined that the text “Modeline “1680×” was not located in xorg.log 142, processing ends.
  • It will be apparent, therefore, that the method of this embodiment could readily be used to check for other supported resolutions, or to set the resolution of one or more monitors to some other value or values as desired.
  • It will also be appreciated that other features known in electronic gaming machines and the games provided thereby can be advantageously and synergistically combined with the features described above.
  • Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
  • In the claims that follow and in the preceding description of the invention, except where the context requires otherwise owing to express language or necessary implication, the word “comprise” or variations such as “comprises” or “comprising” is used in an inclusive sense, that is, to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
  • Further, any reference herein to prior art is not intended to imply that such prior art forms or formed a part of the common general knowledge in any country.
