DESCRIPTION

The present invention relates in general to a gaming device, and more particularly to a gaming device having a masked award game.

BACKGROUND OF THE INVENTION

Gaming devices, such as slot machines, having primary and secondary or bonus games or schemes are well known. One well known bonus game provides a player with a series of potential awards consisting of credits or dollars. For example, in U.S. Patent No. 6,102,798, the processor of the gaming device or the player selects a segment from a grid of player selectable segments. The selected segments reveals whether or not a prize value is associated with that segment.

Another known game is Hasbro, Inc. board game “Battleship.” This game consists of a two players each receiving an identical pegboard and a plurality of ships. The provided plurality of ships consists of a fleet of ships of various sizes, each ship with a plurality of pegs that engage the pegboard. Each player arranges their ships around their respective pegboard. The game proceeds with each player attempting to determine the location of the other players ships on the pegboard. By selecting and announcing a specific location on the pegboard, each player attempts to discover the arrangement of the other player’s ships on the pegboard. If the announced location corresponds with at least one of the pegs of the other player’s ships, it’s a “hit”. An opponent’s ship is eliminated or “sunk” by selecting the location of all the pegs on which the ship sits. The first player to eliminate all the opposing players ships wins the game.

Furthermore, U.S. Patent No. 6,309,299 discloses of a gaming device with a video display configured as a matrix upon which scores can accumulate. Specifically, U.S. Patent No. 6,309,299 provides a grid with icons located on the grid itself. The gaming device selects one of the segments on the grid and if the gaming device selected location is associated with an icon, the player is awarded a bonus score. In another embodiment of U.S. Patent No. 6,309,299, the icons are obscured and a player attempts to locate the obscured icons on the grid. If the player successfully reveals an obscured icon, the player is awarded a score for the revealed icon. A shortcoming of U.S. Patent No. 6,309,299 is that it does not allow the gaming device to select locations of obscured icons on the grid. Additionally, U.S. Patent No. 6,309,299 does not a allow a combination of the gaming device and the player to select locations of obscured icons on the grid. There is a need for new and different gaming devices related to this type of masked award game.

SUMMARY OF THE INVENTION

The present invention provides a gaming device having a game with masked awards associated with segments of a grid. The game of the present invention may be provided in a primary or base game or a secondary or bonus game. The present invention is discussed and illustrated primarily with respect to a two dimensional grid, however it should be appreciated that a three dimensional grid may be employed in accordance with the present invention. In one embodiment of the present invention, upon the initiation of the game, the gaming device randomly associates a plurality of awards, such as a credit amount, a dollar amount or a modifier, with a plurality of segments of a grid.

The associated awards are not initially revealed to the player. It should be appreciated that in one preferred embodiment, the number of awards are less than the number of segments of the grid resulting in a plurality of grid segments, each with no associated award. The gaming device provides a player with a number of opportunities to select segments of the grid by independently indicating both a first or horizontal coordinate and a second or vertical coordinate. It should be appreciated that the coordinates may be other than horizontal and vertical in accordance with the present invention. The number of opportunities may be pre-determined, randomly determined or determined during the play of, for example, a base game. The processor of the gaming 2

CA 02492415 2005-01-12

WO 2004/012159

PCT/US2003/022669 device reveals the award, if any, associated with the player selected grid segment. If no award is associated with the selected grid segment, the processor of the gaming device will reveal a ‘miss’ or other no award indication. It should be appreciated that the no award or ‘miss’ indication associated with a player selected grid segment remains revealed for subsequent player grid segment selections. When the player has no remaining opportunities to select grid segments, the game ends and the player obtains an award based on any revealed awards.

In an alternative embodiment, the player independently selects the first or horizontal coordinate of the grid segment to be revealed and the processor of the gaming device randomly selects the second or vertical coordinate. Alternatively, the player independently selects the vertical coordinate of the grid segment to be revealed and the processor of the gaming device randomly selects the horizontal coordinate, in another embodiment, the gaming device randomly, but independently, selects each of the first and second or vertical and horizontal coordinates of the grid segment to be revealed.

In an alternative embodiment of the present invention, after the gaming device has revealed the award, if any, associated with a segment of the grid, the processor of the gaming device may independently change either the first or horizontal coordinate, the second or vertical coordinate or both coordinates of the player fully or partially selected grid segment. The modified grid segment corresponding to the changed coordinate(s) replaces the player’s initial selected segment. This would result in the player no longer obtaining the initial revealed award, if any, associated with the previously revealed segment, but rather the player obtaining the award, if any, associated with the revealed modified grid segment. Alternatively, the player may obtain both awards, if any, the higher award or the lower award. In an alternative embodiment, the processor of the gaming device may change the coordinates of a player selected grid segment a number of times. In a further alternative embodiment, each award associated with a selected grid segment is offered to the player. The player may accept the award and end the game or may reject the award in hope of achieving a higher award associated with another grid segment. In one such embodiment, after a plurality of changes to the offered awards, a final award is provided to the player. The awards offered to the player may be determined using any of the 3

CA 02492415 2005-01-12

WO 2004/012159

PCT/US2003/022669 alternative embodiments set forth herein. Thus, it should be appreciated that the present invention may be employed in an offer/acceptance type primary or secondary game of a wagering gaming device.

In an alternative embodiment, a plurality of usable symbols are associated with a plurality of awards. In this embodiment, each usable symbol may be associated with more than one grid segment. This embodiment proceeds as described above, however a player may obtain an award only from a completely revealed usable symbol. This embodiment allows the player to partially reveal a usable symbol and not obtain the award associated with the usable symbol until the usable symbol is completely revealed. It should be appreciated that in one such embodiment, if the player has no remaining opportunities to select grid segments, the player will not obtain any award for any partially revealed usable symbols.

In an alternative embodiment of the present invention, a plurality of first or horizontal coordinates and a plurality of second or vertical coordinates are associated with a masked value, such as a credit or dollar amount. Additionally, a plurality of grid segments are associated with an award, such as a modifier. The value, if any, associated with each horizontal and each vertical coordinate is not initially displayed to the player. Upon the initiation of the game, the gaming device prompts the player to independently select each of a horizontal and a vertical coordinate that corresponds to a grid segment. Once selected, the gaming device reveals the award associated with the selected grid segment. The gaming device also reveals the values, if any, associated with the selected horizontal and vertical coordinates. The player’s award, if any, is a combination of the value associated with the selected horizontal coordinate, the value associated with the selected vertical coordinate and the revealed award associated with the selected grid segment.

It is therefore an advantage of the present invention to provide a gaming device with a masked award game.

Other objects, features and advantages of the invention will be apparent from the following detailed disclosure, taken in conjunction with the accompanying sheets of drawings, wherein like numerals refer to like parts, elements, components, steps and processes.

Masked Award Game

Referring generally to Figs. 3A to 3E, one embodiment of the masked award game of the present invention provides a screen or display which displays a plurality of segments of a grid. The present invention is discussed and illustrated primarily with a grid composed of six independently selectable first or horizontal and six independently selectable second or vertical coordinates; however, it should be appreciated that any suitable number of each coordinate may be employed in accordance with the present invention. Each segment has a corresponding horizontal and vertical independently selectable coordinate that indicates its relative position on the grid. The screen or display is preferably a touch screen, which in certain embodiments enables the player to select a grid segment to obtain an award. The screen displays a plurality of segments of the grid. The gaming device preferably provides a plurality of awards, such as a credit amount, a dollar amount, one or more free games, or a modifier, which are randomly associated with a plurality of segments of the grid. Each grid segment preferably does not initially display the award, if any, associated with the grid segment. Alternatively, a plurality of grid segments may be associated with additional player opportunities to select grid segments, usable symbols associated with awards or any combination thereof. It should be appreciated that in one embodiment, there are more grid segments than awards. Thus, a plurality of segments of the grid will each have no associated award. In alternative embodiments, there are less grid segments than awards or the same number of grid segments and awards.

The gaming device may randomly select the award associated with each grid segment from a pre-determined pool of award. Alternatively, the gaming device may have multiple pre-determined pools of awards. Alternatively, the gaming device may randomly select awards from a pre-determined range of awards. The awards associated with any grid segment are preferably randomly determined each time the game is triggered.

At the onset of the game, the gaming device determines the number of opportunities the player will have to select segments of the grid. It should be appreciated that the number of opportunities may be randomly determined, predetermined or determined otherwise such as in a primary game if the game of the present invention is employed as a secondary game. For example, the 9

CA 02492415 2005-01-12

WO 2004/012159

PCT/US2003/022669 number of opportunities may be related to the player’s wager during the primary game. For increased entertainment, the number of remaining opportunities to select grid segments may not be revealed to the player. Each time the player selects a grid segment, the number of opportunities to select a grid segment is decreased by one.

Upon the triggering of the game, in one embodiment, the gaming device prompts the player to select a grid segment by independently inputting a first or horizontal coordinate and a second or vertical coordinate. The processor of the gaming device reveals the award, if any, associated with the player selected grid segment. If no award is associated with the selected grid segment, the processor of the gaming device will reveal a ‘miss’ or other no award indication. It should be appreciated that the no award or ‘miss' indication associated with a player selected grid segment remains revealed for subsequent player grid segment selections. When the player has no remaining opportunities to select grid segments, the game ends and the player obtains a combination of any revealed awards. A display device displays to the player any award obtained as well as the number of remaining opportunities to select segments of the grid remaining. In an alternative embodiment (not shown), after the player has obtained an award, the gaming device reveals the awards associated with the non-selected grid segments. This provides increased entertainment to the player by revealing all the potential awards the player could have obtained during the game.

Referring to Fig. 3A, the gaming device provides a segmented grid 100. Upon the initiation of the game, the gaming device provides the player a number of opportunities to select grid segments. In this case, the gaming device provided the player two opportunities, displayed in the picks remaining display

152. In this embodiment, there are six independently selectable vertical coordinates 102, 104, 106, 108, 110, and 112 labeled A, B, C, D, E and F, respectively. The are also six independently selectable horizontal coordinates

114, 116, 118, 120, 122 and 124 labeled 1, 2, 3, 4, 5 and 6, respectively. The gaming device prompts the player to select a grid segment by independently selecting one vertical coordinate and one horizontal coordinate. As seen in Fig.

3B, the player selected grid segment B-4 by individually and independently selecting highlighted vertical coordinate B numbered 130 and highlighted 10

CA 02492415 2005-01-12

WO 2004/012159

PCT/US2003/022669 horizontal coordinate 4 numbered 132. The gaming device subsequently reveals the award, if any, associated with the player selected grid segment. As revealed in Fig. 3C, selected grid segment B-4 had no associated award as indicated by the highlighted “miss 0” symbol 160. Accordingly, the award amount display 150 displayed an award amount of zero. Appropriate messages such as “PLEASE SELECT YOUR VERTICAL AND HORIZONTAL COORDINATES” and “YOUR SELECTED GRID SEGMENT IS B-4 WHICH HAS AN AWARD OF ZERO CREDITS” are preferably provided to the player visually, or through suitable audio or audiovisual displays.

Since the player had at least one pick remaining 152, the gaming device prompts the player to select another grid segment by independently selecting one vertical coordinate and one horizontal coordinate. It should be appreciated that the “miss 0” symbol 160 of revealed grid segment B-4 remains revealed for subsequent player grid segment selections. As seen in Fig. 3D, the player next selected grid segment E-2 by individually and independently selecting highlighted vertical coordinate E numbered 134 and highlighted horizontal coordinate 2 numbered 136. As revealed in Fig. 3E, selected grid segment E-2 had an associated award amount of five credits as indicated by the highlighted “Hit 5” symbol 162. Accordingly, the award amount display 150 displayed the revealed award amount of five. Appropriate messages such as “PLEASE SELECT YOUR VERTICAL AND HORIZONTAL COORDINATES” and “YOUR SELECTED GRID SEGMENT IS E-2 WHICH HAS AN AWARD OF FIVE CREDITS” are preferably provided to the player visually, or through suitable audio or audiovisual displays. With zero picks remaining 152, the player obtains a combination of all the revealed awards, in this case five, and the game ends. In an alternative embodiment of the present invention, the processor randomly associates the values or hits and the non-values or misses with the grid segments or pairs of coordinates after each pair or designated numbers of coordinates is selected by the player.

In an alternative embodiment of the present invention, the player independently selects the first or horizontal coordinate and the processor of the gaming device randomly selects the second or vertical coordinate. Alternatively, the player independently selects the vertical coordinate and the processor of the gaming device randomly selects the horizontal coordinate. Thus, each selection 11

CA 02492415 2005-01-12

WO 2004/012159

PCT/US2003/022669 of a grid segment is determined in part by the player and in part randomly by the processor of the gaming device. This embodiment provides increased entertainment to the player because the player has only a partial control in selecting the grid segment that represents their award. In another embodiment, the processor of the gaming device randomly, but independently, selects each of the first and second or vertical and horizontal coordinates of a grid segment. It should be appreciated that during the play of a single game, the processor of the gaming device may independently select the first or horizontal coordinate of one grid segment selection and subsequently independently select the second or vertical coordinate of the following grid segment selection. It should further be appreciated that in one embodiment of the present invention, after the value associated with horizontal and vertical coordinates are revealed, such as “0 for coordinate B4 in Fig. 3C, the player or the processor may change one of the coordinates (such as coordinate “4” to coordinate “2”). The gaming device would then reveal the value associated with the new coordinate. The changing of one coordinate could be allowed by the game one or more consecutive times by the player or randomly by the processor.

Referring in general to Figs. 3F and 3G, in an alternative embodiment of the present invention, after the gaming device has revealed the award, if any, associated with a segment of the grid, the processor of the gaming device may independently change either the first or horizontal coordinate, the second or vertical coordinate or both coordinates of the player fully or partially selected grid segment. The modified grid segment corresponding to the changed coordinate(s) replaces the player’s initial selected grid segment. This would result in the player no longer obtaining the revealed award, if any, associated with the initial revealed segment, but rather the player obtaining the award, if any, associated with the revealed modified grid segment. Alternatively, the player may obtain both awards, if any, the higher award or the lower award.

This embodiment provides increased entertainment to the player because the player is shown the revealed awards that the player might have obtained had the gaming device not intervened and selected another grid segment. In an alternative embodiment, the processor of the gaming device may subsequently independently change the coordinates of the revealed modified grid segment.

In another embodiment, each time the processor of the gaming device modifies 12

CA 02492415 2005-01-12

WO 2004/012159

PCT/US2003/022669 the player's selected segment with a modified grid segment, the player may accept or reject the award associated with the modified grid segment. The player may be given the accept/reject option before or after the award associated with the modified grid segment is revealed to the player.

As seen in Fig. 3F, after the player independently selected the coordinates for two grid segments (segments B-4 numbered 160 and E-2 numbered 162) that revealed the awards of zero and five, respectively, the . processor of the gaming device has randomly, but independently selected new horizontal coordinate 6 numbered 138 as the horizontal coordinate of the player’s last selected grid segment. As revealed in Fig. 3G, selected grid segment E-6 had an associated award amount often credits as indicated by the highlighted “Hit 10” symbol 164. Accordingly, the award amount display 150 displayed the modified revealed award amount often. It should be appreciated that the player may obtain a combination of the award associated with the player selected grid segment and the award associated with the gaming device modified grid segment. Appropriate messages such as “YOUR NEW HORIZONTAL COORDINATE IS 6” and “YOUR MODIFIED GRID SEGMENT IS E-6 WHICH HAS AN AWARD OF TEN CREDITS” are preferably provided to the player visually, or through suitable audio or audiovisual displays.

In an alternative embodiment of the present invention, the game proceeds as described above, however, the processor of the gaming device prompts the player to select a plurality of first horizontal coordinates and a plurality of second or vertical coordinates. The processor of the gaming device randomly, but independently, selects one horizontal and one vertical coordinate from the player selected pluralities of horizontal and vertical coordinates. The processor selected horizontal and vertical coordinates correspond to the grid segment to be revealed. This embodiment provides increased entertainment to the player because the revealed grid segment is determined in part by the player and in part randomly by the processor.

Referring generally to Figs. 4A and 4B, in an alternative embodiment of the present invention, a plurality of usable symbols are associated with a plurality of segments of the grid. Each usable symbol may be associated with more than one grid segment. In this embodiment, each usable symbol is associated with an award amount or a modifier. The game proceeds as 13

CA 02492415 2005-01-12

WO 2004/012159

PCT/US2003/022669 described above, however, if a selected grid segment is associated with a usable symbol that is associated with more than one grid segments, then the player obtains no award until the entire usable symbol is revealed. For increased entertainment, the award amount or modifier associated with each usable symbol may not be revealed to the player until the end of the game. This embodiment may result in the player independently selecting the coordinates of a grid segment only to reveal a partial usable symbol, but with no remaining opportunities to select segments, the player will not obtain any award, resulting in increased excitement and entertainment for the player.

As illustrated in Fig. 4A, after previously selecting two grid segments (segments B-2 numbered 166 and D-4 numbered 166) that revealed no usable symbol, the player next selected grid segment F-2 by individually and independently selecting highlighted vertical coordinate F numbered 140 and highlighted horizontal coordinate 2 numbered 142. As revealed in Fig. 4A, selected grid segment F-2 reveals only a partial usable symbol 168. After revealing a partial usable symbol, the player’s next selection would logically be a grid segment adjacent to the partially revealed usable symbol to reveal the entire usable symbol. In this case, as revealed in Fig. 4B, the player next selected grid segment E-2 by individually and independently selecting highlighted vertical coordinate E numbered 144 and highlighted horizontal coordinate 2 numbered 146. The selected grid segment E-2 reveals the other portion of the partially revealed usable symbol in segment E-2. The usable symbol associated with grid segments E-2 and F-2 numbered 170 had an associated award amount of thirty credits, as displayed in the award amount display 150. With zero picks remaining 152 and an entire usable symbol revealed, the player obtains the award associated with the revealed usable symbol and the game ends. It should be appreciated that had the player if zero picks remaining after revealing the partial usable symbol, the game would end with the player receiving no award for any partially revealed usable symbols.

In an alternative embodiment of the present invention, a plurality of first or horizontal coordinates and a plurality of second or vertical coordinates are associated with masked values, such as credit or dollar amounts. Additionally, a plurality of grid segments are each associated with a plurality of awards, such as a modifier. The masked values, if any, associated with each first or 14

CA 02492415 2005-01-12

WO 2004/012159

PCT/US2003/022669 horizontal and each second or vertical coordinate are not initially displayed to the player. The awards, if any, associated with each grid segment are not initially displayed to the player. Upon the initiation of the game, the gaming device prompts the player to independently select a first or horizontal and a second or vertical coordinate that corresponds to a grid segment. Once selected, the gaming device reveals the award, if any, associated with the selected grid segment. The gaming device also reveals the masked values, if any, associated with the independently selected horizontal and vertical coordinates. In an alternative embodiment, the gaming device reveals the awards associated with each horizontal coordinate, each vertical coordinate and each grid segment. The player’s award, if any, is based on or a combination of the value associated with the independently selected horizontal coordinate, the value associated with the independently selected vertical coordinate and the revealed award associated with the selected grid segment.

As illustrated in Fig. 5A, the player had already independently selected their horizontal and vertical coordinates. In this case, the player individually and independently selected highlighted vertical coordinate C numbered 148 and highlighted horizontal coordinate 2 numbered 149. As shown in Fig. 5A, the processor of the gaming device revealed the selected grid segment C-2 which had an associated modifier of 3X numbered 172. As revealed in Fig. 5B, the processor of the gaming device revealed the award amounts associated with each horizontal coordinate 180 and each vertical coordinate 182. With zero picks remaining 152, the player obtains an award of forty-eight credits. The player’s award is a combination of one 182 (the value assigned to independently selected vertical coordinate C) plus fifteen 180 (the value assigned to independently selected horizontal coordinate 2) multiplied by three (the revealed modifier associated with grid segment C-2) as displayed in the award amount display 150.

A further example of one embodiment of the present invention is illustrated in Figs. 6A to 6D. In Fig. 6A, the display device displays a plurality of columns labeled 1 through 6 and a plurality of rows labeled A through F. The player is directed to select a vertical coordinate and a horizontal coordinate. As illustrated in Fig. 6B, the player selects horizontal coordinate column 5 and the display device displays the value associated with the horizontal coordinate 5 15

PCT/US2003/022669 which is 40. The display device also highlights column 5 and informs the player to select the vertical coordinate. As further illustrated in Fig. 6C, the player selects the vertical coordinate F and the display device reveals the value of 20 associated with the coordinate or row F as well as the multiplier 5X or other modifier associated with the coordinate grid segment F5. The display device informs the player that the player’s selected vertical coordinate is F which has a value of 20, the selected horizontal coordinate is 5 which has a value of 40, and the selected grid segment is .F-5 which has a multiplier of 5. The display device also informs the player that the total award is 300 and that the player may keep this award or change one of the coordinates to obtain another award.

As further illustrated in Fig. 6D, the player changes the vertical coordinate to D and the display device displays the award value of 100 associated with the coordinate D. The multiplier associated with grid segment D5 is 4X. The gaming device display also informs players that the player’s new selected coordinate is D which has an award value of 100, that the selected horizontal coordinate is 5 which has an award value of 40, and that the selected grid segment is now D5 which has a multiplier of 4. The display device also informs the player that the total award is 560 credits. In one embodiment which enables the player to make only one change of a coordinate, the player is provided the award after the change if the player decides to make the change.

In other alternative embodiments, the gaming device may enable the player to change the coordinates more than once. Alternatively, the gaming device may allow one change of each coordinate, multiple changes of one coordinate, multiple changes of both coordinates and variations thereof. The gaming device may also determine the number of changes based on some other random event or player interactive event or otherwise. Alternatively, the processor may randomly make the changes or the player and the processor may each make one or more of the changes. It should also be appreciated that in one embodiment of the present invention, the display device may display to the player or reveal to the player the ranges of values in the rows, or in and/or columns each of the different rows and/or columns and the range of multipliers or other modifiers in the grid segments which enables the player to make informed decisions. Accordingly, it should be appreciated that if the player picks a high value in a row or column, the player may want to change the other 16

PCT/US2003/022669 coordinate to obtain a maximum corresponding value and corresponding multiplier.

It should also be appreciated that the modifier could alternatively be other awards such as bonus credits or awards represented by bonus game symbols, bonus games represented by bonus game symbols, free game or spins represented by free game or spin symbols, and other usable or function elements of a game represented by usable symbols.

In another alternative embodiment, as illustrated in Figs. 7A to 7C, the gaming device displays more than two coordinates such as three coordinates in a three dimensional grid with first or horizontal, second or vertical and third or depth coordinates. This embodiment proceeds as described above, however since there are three coordinates for each grid segment, in alternative embodiments, the player may individually and independently select zero, one, two or three coordinates of a grid segment to be revealed, with the processor of the gaming device randomly but independently selecting three, two, one or zero coordinates, respectively.

Referring to Fig. 7A, the gaming device provides a segmented three dimensional grid 200. Upon the initiation of the game, the gaming device provides the player a number of opportunities to select grid segments. In this case, the gaming device provided the player one opportunity, displayed in the picks remaining display 252. In this embodiment, the gaming device prompts the player to select one of four independently selectable horizontal coordinates 202, 204, 206 and 208 labeled 1,2, 3 and 4, respectively. In this embodiment, the gaming device will randomly, but independently, select the other coordinates of the grid segment to be revealed. As seen in Fig. 7B, the player individually and independently selected highlighted horizontal coordinate 4 numbered 208. The gaming device randomly but independently selected coordinates D numbered 212 and I numbered 214. As revealed in Fig. 7C, selected grid segment D-4-I had an associated award of twenty as indicated by the highlighted “hit 20” symbol 220. Accordingly, the award amount display 250 displayed an award amount of twenty. Appropriate messages such as “PLEASE SELECT YOUR HORIZONTAL COORDINATE” and 'YOUR
