The foregoing summary, as well as the following detailed description of certain embodiments of the present invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, certain embodiments are shown in the drawings. It should be understood, however, that the present invention is not limited to the arrangements and instrumentality shown in the attached drawings.
DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
Referring to FIG. 1, a gaming device 11 is in the form of a video slot machine having a game display, generally indicated at 13, for presenting game content to the player. Display 13 may be formed from a video display device 14, as for example, a liquid crystal display (LCD), a cathode ray tube display (CRT), a plasma display, or other type of video display, and is controlled to display five (5) simulated spinning reels 15, 17, 19, 21 and 23. When the reels stop game symbols are displayed in the game display 13 in matrix-form.
It will be understood that instead of providing a video display unit which displays representations of reels, actual, electro-mechanical reels may be used. Such gaming machines including actual rotatable reels are commonly termed stepper machines. For example, in an alternative embodiment, the gaming device 11 may be implemented as an electromechanical reel-based slot machine having a content display area 13 with spinning stepper reels 15, 17, 19, 21, and 23 rotating in the game display area 13. The game may have fewer or more reels as desired. The game display area 13 may be surrounded by a video display device 14, for example. Where a transmissive display is used the transmissive display may overlay the game display area 13. Video displays (e.g., LCD, CRT, plasma, etc.) and/or other illuminating or light sources (e.g., lamps, light emitting diodes (LEDs), etc.) may also be integrated with spinning reels 15, 17, 19, 21, and 23 to illuminate or animate desired display locations such as pay lines, pay combinations, winning lines, winning combinations, special symbols, etc.
Lighting may also be used to backlight symbols and/or generating a flickering or flashing effect as the electro-mechanical reels 15, 17, 19, 21, and 23 spin, for example. In certain embodiments, one or more light sources may be used with one or more filters to adjust certain characteristics of light emitted by the one or more light sources (e.g., altering lamp light to simulate natural daylight), for example.
To operate gaming device 11, the player enters a wager (money wager, wager of accumulated credits, etc.) and prompts device 11 to generate and display an outcome at the content display 13. If the outcome is a winning outcome, the player is awarded credits, coins, tokens, vouchers, etc. If the outcome is a losing outcome the player receives no award.
The outcome may be determined, for example, by the combination of symbols which appear in game display 13. Each of the five spinning reels carries a plurality of symbols, and when stopped presents one or more symbols in the game display 13. The symbols displayed may be associated with pay lines 18, 20, 22 or may represent “scatter” wins (a predetermined number of symbols displayed anywhere in the game display 13). Five symbols may appear along each horizontal “line” or row 18, 20, 22 of content display 13: For example, the middle line 20 may be the line upon which the outcome is determined. As shown in FIG. 1, middle line 20 has the combination of five symbols “Q”, a “crown”, “J”, “K” and “Q”. The top line 18 and the bottom line 22, may also have symbols and form two other pay line combinations of five symbols, which may be used to determine wins. Thus, an array of 3 by 5 symbols appears as the content display. More than three pay lines may be available for the player to wager upon.
Each of the symbols on the five reels is predefined prior to game play. There may be more than twenty different symbols that are carried by each of the five reels, and yet only three symbols of each reel are displayed.
Device 11 operates under control of a game control processor unit 25 disposed within a housing 27 of device 11. Game control processor unit 25 accounts for the wager input, randomly selects the outcome of the game and controls the five reels (the display 14) so as to display the selected outcome in content display 13 at a time after play was initiated. This time may be predetermined.
Gaming device 11 includes a complementary display area 29 shown in the illustrative embodiment as surrounding the game display area 13. Complementary display area 29 may be formed as a border of a portion of the video display device 14 (as shown in FIG. 1), e.g., on the same display as the game display area, or display area 29 may be a separate flat screen (not shown) which surrounds all or a portion display device 14. Complementary display area 29 is controlled to display an image having characteristics including color to complement and enhance the visual aspects of the game and one or more particular outcomes. Complementary display area 29 may be controlled to generate light, and more particularly, a particular color of light, a particular brightness of light, a particular flashing pattern of light, etc.
In addition to, or instead of, complementary display 29, an illuminated panel 31 may be provided to generate a light characteristic. Panel 31 surrounds the video display device 14. Panel 31 is adapted to be illuminated to one or more light characteristics, generated singly (green light, for example) or in combination (green light which is flashing, for example).
Referring now to FIG. 2, a symbol 35 which may be displayed on a vertical reel 15, 17, 19, 21, 23 has a shape of the letter K. Symbol 35 has a primary color of orange, and is positioned on a square shaped background 37 which is colored white to provide a white background to the orange “K”. In addition, other markings 39 such as strokes, are colored black, and are also placed on white background display 37. Also, symbol 35 is outlined in the color black by outline marking 41.
In this example, the entire square background 37 may be located on each of the reels. That is, each of the five reels may carry the “K” symbol 35. For example, as shown in FIG. 1, the symbol “K” is shown on reels 15, 17 and 21, appearing in rows 18 and 20, when one particular outcome of the game is finally displayed to the player. The other two reels 19, 23 may also carry the “K” symbol, which may be presented in content display 13 from time to time as the game is played. The distribution of the symbols on the reels determines the odds for obtaining predetermined combinations of those symbols, e.g. three K's on a pay line.
Processor unit 25 (FIG. 1) controls the particular display characteristic generated by complementary display area 29 and/or panel 31. The particular display characteristic generated by processor unit 25 is dependent on one or more particular symbols being displayed in content display 13 at a time during play of the game. For example, the display characteristics may be generated at the time the outcome is first displayed in game display 13, i.e., when the reels stop spinning, and continue to be generated for several seconds thereafter (e.g., three (3) seconds thereafter) or until the next outcome is displayed at the game display 13. The time duration of the generated display characteristic may be of a predetermined length of time (e.g., three (3) seconds) or may be shortened in real time as the player activates play again within three seconds of the reels stopping. As will suggest itself, the display characteristic may be generated for a fixed period of time longer than three (3) seconds or by a variable period determined according to the time that the next play is commenced by a player.
For example, when a winning combination of the “K” symbols 35 are displayed (either on an active pay line or as a scatter prize, processor unit 25 controls the complementary display 29 or panel 31 to display a complementary color of, for example, a light orange color to complement the primary color of the subject symbol 35. The complementary display 29 may include in the light orange display graphics such as a pattern of small “K”s to further highlight the winning outcome. Where the complementary display 29 is transmissive and overlays electro-mechanical reels, only portion overlying the winning symbols may be controlled to provide the display of the complementary color and graphics.
The orange color is associated in the mind of the player with the orange colored “K” symbol. The “K” symbol may be one of the important symbols of the game, as one defining an award. The player thus seeks to find an orange “K” in the game display 13. The orange color facilitates such seeking by the player, and stimulates the player through his or her eyes.
The intensity (brightness) of the orange color generated in complementary display area 29 and/or panel 31 may be increased in accordance with the number of “K” symbols appearing in the winning symbol combination. When three “K” symbols appears in winning outcome an orange color of a first intensity level is generated in complementary display area 29 and/or panel 31. When four “K” symbols appear in row 20, the orange color of a second intensity level greater than the first intensity level is generated in complementary display area 29 and/or panel 31. Likewise, greater intensity levels may be generated in complementary display area 29 and/or panel 31 five “K” symbols, respectively, appear in row 20.
Referring to FIG. 3, the association of the display of at least a complementary color at complementary display 29 is shown. The game display may produce an outcome of five symbols 45, 47, 49, 51, 53 each of which has graphic characteristics such as color(s), shape etc. In one embodiment the controller 57 may control the complementary display 29 to display a color, or colors, with or without graphics to complement the display of all game symbols or selected ones of the symbols or symbols associated with a winning outcome. Where all symbols are considered the controller 57 may control the complementary display to display the dominant color for all symbols displayed or for the group of certain symbols or the color complement (opposite color) of those symbols. Accordingly each symbol may be assigned a color weighting and when the symbols are displayed the controller 57 sums the weighting and generates at the complementary display 29 a color corresponding to the average color or the dominant color, or the color corresponding to the symbol having the greater number in the display or according to any other selected protocol. In addition to the selected color displayed in the complementary display 29, graphics such as representations of game symbols or images consistent with the theme of the game may be included. Further the complementary display 29 may display more than one color associated with the display of game symbols.
Referring to FIG. 4, processor unit 25 may include a random number generator 61 which generates, for example, five (5) random numbers 63, 65, 67, 69, 71 upon activation of gaming device 11 to initiate play of a game and to develop the content display 13 (FIG. 1). Each random number determines the reel stop position of a respective display reel 15, 17, 19, 21, 23. For example, the first random number 63 causes a designated symbol carried by the first reel 15 to appear in row 20 of the content display. The second random number 65 causes a designated symbol carried by the second reel 17 to appear in row 20 of the content display. Likewise, the third random number 67, fourth random number 69, and the fifth random number 71 causes respective designated symbols carried by the respective third, fourth and fifth reels to appear in row 20 of the content display.
Processor unit 25 utilizes the first random number 63 to designate, i.e., identify, a particular reel stop of the first reel. A look-up table 73 identifies the particular symbol that corresponds to a particular reel stop identified by the random number. The symbol corresponding to the reel stop selected by the first random number 63 is then displayed in row 20 of the content display. For example, random number RN#3 stops the reel at reel stop 3 and a “Q” symbol is displayed on middle row 20.
In an embodiment to determine the color to be displayed is shown with reference to FIG. 5. A second look-up table 75 may be used to identify a designated color and/or a light characteristic to be associated with a symbol to be displayed in content display 13. As shown in the first row 77 of look-up table 75, the symbol “Q” is associated with a designated color “gold”. The symbol “Q” is also associated with a light characteristic of gold light. Thus, the symbol Q is colored in gold and appears as a gold symbol “Q” to the player. In addition, the area 29 and/or panel 31 will generate gold light when the symbol Q is displayed in the content display.
As will suggest itself, table 75 (FIG. 5) may be incorporated directly into look-up table 73 (FIG. 4).
The term “designated color” is meant a color that is associated with a particular symbol. As discussed with respect to FIG. 2, the symbol “K” 35 is colored orange. Thus, orange is the designated color of the symbol “K”. The player will associate orange with the “K” because of the “K's” visual appearance.
Referring again to FIG. 5, in the second row of table 75, the symbol “K” is associated with a designated color orange. The symbol “K” is also associated with the light characteristic of orange light.
In the third row of table 75, two “Q” symbols are associated with gold flashing light. If two “Q” symbols appear in the row 20 of the content display, the light characteristic associated with such an event is flashing gold light. Complementary display area 29 and/or panel 31 will be controlled to generate flashing gold light.
In the fourth row of table 75, two “K” symbols are associated with orange flashing light. If two “K” symbols appear in row 20 of the content display, the light characteristic generated by complementary display area 29 and/or panel 31 is flashing orange light.
As shown in FIG. 5, the fifth row of table 75 identifies the event when one “K” and one “Q” symbol both appear in row 20. In such an event, the light characteristic for such an event is a flash of gold, and then a flash of orange which may be repeated through out a time period, for example, 3 seconds.
As will suggest itself, other symbols may designate a particular color, and be associated with particular light characteristics. In addition, other combination of symbols may be associated with particular light characteristics.
When processor unit 25 generates five random numbers, the particular light characteristics will become known to the processor unit 25 by using those five random numbers and the look-up table 75. The processor will then activate a controller, such as controller 57 of FIG. 3, in order to control the display area 55 to generate the light characteristic(s) identified in table 75.
Referring again to FIG. 3, controller 57 may control light display 55 in an attenuated manner so as not to distract the player. That is, the light displayed may be subtle or soft, and thus not the primary focus of the player's attention. The player's primary attention will be on the symbols coming to rest in content display 13. In certain embodiments, the light displayed may resemble natural light, for example.
As another embodiment, the color of the light form display 65 may change based on a combination of the colors indicated by dominant symbols (symbols which play a part in a winning outcome) displayed over several outcomes.
For example, assume that no dominant symbol has occurred for at least two plays. Then an orange “K” in the following first outcome, a red “J” in the following second outcome, and a red “J” in the following third outcome may generate orange light from display 55 in the first outcome, and then adjust the light from display 55 to an orange-red light in the second outcome, and then adjust the light from display 55 still further to an orange-red-red light (one part orange, 2 parts red) in the third outcome. In such an example, the three last outcomes are used to control the light characteristics of display 55; the colors designated by the dominant symbols of the three last outcomes are combined as colors of light, and complementary display area 29 shifts from one combined color of light to the next as the gaming device is played. The color (and graphics if included) is continuous through these three plays but is varied in color between plays.
As another embodiment, the color of the complementary display area 29 or panel 31 would change only when a win outcome was presented. Such a change would occur when the reels stopped, or may occur shortly before the reels stopped, e.g., one second before the reels stopped. The light may persist until the next game is played, or end or fade off after two or three seconds.
As understood, several modifications may be made to the examples given, without departing from the spirit or scope of the invention. In addition, both displays 29 and 31 may be controlled separately to display different light characteristics, as for example, different colors of light. More than two displays may be controlled. Instead of displays adjacent to the symbol display, light characteristics could be made in the belly glass, coin tray or other locations in eye-view of the player.
The components, elements, and/or functionality of the system(s) described above may be implemented alone or in combination in various forms in hardware, firmware, and/or as a set of instructions in software, for example. Certain embodiments may be provided as a set of instructions residing on a computer-readable medium, such as a memory or hard disk, for execution on a processor-based video or electromechanical gaming machine.
FIG. 6 illustrates a flow diagram for a method 600 for providing a game display to a player in accordance with an embodiment of the present invention. At step 610, a game display area is provided for display of game content.
At step 620, a plurality of symbols are predefined.
At step 630, several ones of a plurality of symbols are displayed to a player. For example, two like symbols are displayed to the player. As another example, several symbols may be displayed at a game time relative to initiation of a game by a player.
At step 640, a color is designated for association with at least one of the plurality of symbols. A complementary display area is to be provided separate from the game display area, for example.
At step 650, the color is generated to the player at a color light time during which the one of the plurality of symbols is displayed. For example, the color time commences when one of the plurality of symbols is first displayed. As another example, the color light time occurs for a predetermined length of time. Color light time may commence at a game time relative to initiation of a game by a player, for example. In certain embodiments, generated and displayed light may a light characteristic instead of and/or in addition to the light color for display. Light may be displayed in the separate light display area, for example.
One or more of the steps of the method 600 may be implemented alone or in combination in hardware, firmware, and/or as a set of instructions in software, for example. Certain embodiments may be provided as a set of instructions residing on a computer-readable medium, such as a memory, hard disk, DVD, or CD, for execution on a general purpose computer or other processing device.
The complementary display area 29 may also be controlled to display color (and graphics) in association with other game displays such as secondary game displays which may present outcomes in other than matrix-form. For example, if a player is present with a secondary game involving choices between a plurality of icons, the complementary display 20 may display features complementary to the icon selected by the player.
