Contemporary gaming machines, such as slot machines, video poker machines, video blackjack machines and video keno machines, include primary games and often secondary or bonus games. In one known gaming device, when a player obtains a predetermined outcome in a primary game, the gaming device uses a relatively large mechanical spinning wheel to indicate or present a predetermined award to the player. The gaming device then provides the award to the player.
In other known gaming devices, the gaming device causes mechanical dice to rotate when a predetermined event occurs. When the dice stop rotating, the dice display a certain number of dots. Depending upon how many dots are displayed, the player may or may not win a predetermined award.
In one known gaming device having a die rotating device, the die rotating device does not accurately and reliably track the die position, especially after one complete rotation of the die. Specifically, such gaming device includes a commercially available component, known as 1DU DICE UNIT™, which is manufactured by Starpoint Electrics Ltd., Unit 1 King Georges Trading Estate Davis Road, Chessignton, Surrey, KT9 1TT, United Kingdom. This component uses a single optical device to track when face one of a die is facing a player. This component also monitors the number of steps made by the motor. The gaming device processor uses this information to perform a calculation. This calculation takes into account the specific gear ratios of the component and the type of motor used (such as, whether the motor is a twenty-four step motor or otherwise). If the gears do not skip and the motor functions properly, the calculation determines when the die is displaying a second face, a third face and so on. However, if the gears skip or if the motor malfunctions, the calculation yields erroneous information.
As in many devices which involve gears, the gears periodically skip, as is the case with this component. When the gears skip, the component sends signals to the gaming device processor which specify that a particular face is displayed when in reality that face is only partially displayed or worse, a different face is actually displayed to the player. This misinformation is problematic for operators of casinos because it creates frustration and dissatisfaction among the customers.
There are no known gaming devices which use an award indicator which includes award values affixed to a plurality of rotating mechanical dice wherein the dice indicate the award won by the player. In addition, there are no known gaming devices which include numbers or dots affixed to rotating mechanical dice and a table of different ranges of numbers or dots, wherein the ranges are associated with different awards. Furthermore, there are no known gaming devices having die rotators which produce reliable and accurate die position information during and after a complete rotation of the dice.
To increase player enjoyment and excitement, it is desirable to provide players with new gaming devices with new and reliable mechanical award indicators.
The gaming device of the present invention, in one embodiment, includes a plurality of sequentially activated mechanical award indicators and specifically a plurality of rotatable mechanical dice. Each die has at least one award value on or affixed to at least one of the faces of the die, and the gaming device uses the dice to sequentially indicate components of predetermined or randomly determined game outcomes. These game outcomes can occur in primary games or in secondary games, such as bonus rounds. For example, a player may win a predetermined total award in a slot game, wherein different dice rotate to display different components or parts of the total award. In one such embodiment, the sum of all of the partial awards displayed on all of the dice equals the amount of the total award.
In one embodiment of the gaming device, the award indicator includes a plurality of die rotators which rotate a plurality of dice. Each die is the same in structure, but preferably each die bears different award values or award symbols. In one embodiment, each die includes six sides or faces including one visible side or face presented to the player. Preferably, the visible face is pointed downward or outward in the direction of the player, oriented at an angle with respect to the cabinet surface of the gaming device. The award value symbols and other symbols are attached or affixed to each die in any suitable manner, preferably with decals.
In operation, when a predetermined event occurs during a game, the processor, as instructed by a predetermined game program, uses a random number generator to generate an outcome for a player. In one embodiment, the random number generator includes predetermined randomizing instructions and predetermined data stored in the data storage device. The outcome could be any suitable predetermined award value or no value at all. The processor uses the mechanical award indicator of the present invention to indicate the outcome to the player.
Specifically, the award indicator rotates some or all of the dice. The processor stops the rotation of the dice, preferably in a predetermined rotational order (such as from bottom to top), and each die then displays an award value on its visible face. The gaming device provides the player with the sum of all of these award values, and the award indication process terminates.
In another embodiment, the processor operates the award indicator so that the die rotators provide different rotations of the different dice. Each die has a different predetermined rotation, and each die stops rotating at a different time, preferably in a random order. When a die stops rotating, its visible face may or may not display an award value. For example, the visible face may display a value of zero, a terminator symbol or any other predetermined symbol. In any case, the player receives the award values which appear on the visible faces of the die.
In another embodiment, the dice bear award values and multipliers. The term multiplier, as used herein, can include any numerical factor which is used to increase or decrease an award value. Preferably, the multiplier is a number greater than one. After a predetermined event occurs and the processor generates an outcome, the processor causes the award indicator to rotate all of the dice. When the dice stop rotating, the visible faces display either award values or multipliers. If the visible faces display only award values, the player receives the sum of all such award values. If, however, a multiplier is displayed on one or more visible faces, the player receives: (a) the sum of all award values displayed on all of the visible faces multiplied by (b) the sum of all multipliers.
In another embodiment, the gaming device of the present invention includes an award indicator, wherein the die rotators are configured in a vertical or staircase fashion. It should be appreciated, however, that the die rotators can have a vertical, horizontal, circular or any other suitable configuration in this embodiment. In the staircase configuration, one of the dice is mounted at a low position on the cabinet surface and one die is mounted at a higher position on the cabinet surface. One or more dice are positioned between such high and low dice. In this embodiment, the dice bear bonus awards, move indicators and terminator symbols. When the move indicator is obtained, the processor rotates one or more predetermined dice associated with or indicated by the move indicator.
In one example of this embodiment, when a predetermined event occurs during a game, the processor generates an outcome, and initially a die rotator rotates the die at the lowest position on the cabinet surface. When the die rotator stops the rotation of this die, if an upwardly pointing move indicator is displayed on the visible face of this die, the processor causes the next higher die to rotate.
Each time a die rotator rotates and then stops rotating a die, the die's visible face will either display an award value, a move indicator or a terminator. As long as the player avoids move indicators and terminators, the die rotator will repeatedly rotate the same die, stop the die and display an award value. The player will receive all such award values. If the player reaches a move indicator, the next highest die will then be rotated. This process continues until the player reaches the highest die or a terminator symbol, whichever comes first. It should be appreciated that in various embodiments of the present invention, the terminator symbol can indicate the termination of a particular die rotation or the termination of the entire award indication process.
In an alternative embodiment, the move indicator indicates to a player a predetermined number of moves and a direction of movement. For example, a move indicator may bear a label such as, “3 LEFT” or “2 UP.” The gaming device causes one of the dice to rotate in accordance with such indications.
In another embodiment of the gaming device of the present invention, the award indicator includes five die rotators which rotate five dice. Various award values are affixed to each side or face of the dice. Each die is separately associated with a reel in the primary slot game of the gaming device. In addition, the symbols appearing on the reels include at least one predetermined symbol which triggers the award indicator. In operation of one example of this embodiment, a player spins the reels and a die symbol appears on the payline of the reels. The processor determines an outcome for the player. Then the processor causes the die rotator associated with this reel to cause a predetermined rotation of the die in its rotator. When this die stops rotating, the player sees an award value, and the gaming device terminates the award indication process and provides this award value to the player.
In an alternative embodiment of the present invention, the gaming device enables the player to accept or reject certain award values displayed by the dice. The gaming device may enable the player to exercise this option while the dice are rotating or after they stop rotating. Preferably, after the processor causes the dice to rotate, the processor enables the player to accept or reject preferably all of the award values which the dice display to the player. If the player accepts the award values, the gaming device provides the accepted award values to the player, and the award process terminates. If the player rejects the award values, the processor causes the dice to rotate again. This process of accepting or rejecting award values may repeat itself multiple times.
In another embodiment of the present invention, the gaming device includes a predetermined table or scale which includes predetermined ranges of award values, numbers, dots, counting symbols, points or other types of numerical representations displayed on the dice. Each range is associated with a predetermined award value. Depending upon which range a player reaches, the player will obtain different award values.
The die rotator of the gaming device of the present invention can include any suitable electrical and mechanical parts which enable the gaming device to perform predetermined rotations of mechanical dice. In one embodiment, the die rotator includes two optical devices or readers which enable the gaming device processor to track and control the movement of the dice. One such optical device or reader enables the processor to determine when a home face or face one for each die is most visible to the player. The other optical device or reader is connected and secured to the drive shaft or motor shaft of the die rotator. The motor shaft works in conjunction with this optical device to enable the processor to count how many faces pass through the visible position as the die is rotated. When face one passes through the visible position, the processor begins this count which informs the processor as to what face is displayed to the player at any one point in time. Preferably, the die rotator generates the visual effect of tumbling dice in free space with three dimensional movement.
The gaming device of the present invention, in one embodiment, includes an award indicator which involves predetermined rotation of mechanical dice. Preferably, at least one award value is affixed to each of the die. The gaming device uses the mechanical dice to indicate predetermined award outcomes to players. This type of gaming device increases the excitement and entertainment experienced by gaming device players.
It is therefore an advantage of the present invention to provide a gaming device having a mechanical award indicator.
Another advantage of the present invention is to provide a gaming device having an award indicator with rotating mechanical dice.
Yet another advantage of the present invention is to provide an award indicator for a gaming device which provides a player with award information and entertainment.
Still another advantage of the present invention is to enhance the indication of game outcomes to players.
Another advantage of the present invention is to increase the attraction of a gaming device.
Yet another advantage of the present invention is to provide a gaming device which includes mechanical die rotators which reliably provide die position information to the gaming device processor.
Still another advantage of the present invention is to provide a gaming device which uses mechanical dice which bear award values to indicate award outcomes to players.
Additional features and advantages of the present invention are described in, and will be apparent from, the following Detailed Description of the Invention and the figures.
Referring now to the drawings, two embodiments of the gaming device of the present invention are illustrated in
As illustrated in
As shown in
A player may cash out and thereby receive a number of coins corresponding to the number of remaining credits by pushing a cash out button 26. When the player cashes out, the player receives the coins in a coin payout tray 28. The gaming device 10 may employ other payout mechanisms such as credit slips redeemable by a cashier or electronically recordable cards which keep track of the player's credits.
Gaming device 10 also includes one or more display devices. The embodiments shown in
As illustrated in
It is also preferable that the data storage device 40 stores certain dice data, specifically a plurality of outcomes associated with different faces of the dice rotated by the award indicator 37. When the gaming device generates awards, this dice data enables the gaming device to indicate the generated awards by using the mechanical dice, as described in detail below. For verification purposes, after the dice indicate the generated award, the gaming device also displays the generated award at the vacuum fluorescent display (VFD) 39. In case the dice do not accurately indicate the generated award, VFD 39 functions as the official display of the player's award.
As illustrated in
It should be appreciated that although a processor 38 and data storage device 40 are preferable implementations of the present invention, the present invention can also be implemented using one or more application-specific integrated circuits (ASIC's) or other hard-wired devices, or using mechanical devices (collectively or alternatively referred to herein as a “processor”). Furthermore, although the processor 38 and data storage device 40 preferably reside on each gaming device 10 unit, it is possible to provide some or all of their functions at a central location such as a network server for communication to a playing station such as over a local area network (LAN), wide area network (WAN), Internet connection, microwave link, and the like. Accordingly, the processor 38 and memory device 40 can communicate with a suitable network 49. The processor 38 and memory device 40 is at times generally referred to herein as the “computer” or “controller.”
With reference to
In addition to winning credits in this manner, the gaming device 10 may also give players the opportunity to win credits in a secondary game, such as a bonus round. This type of gaming device 10 will include a program which will automatically begin a bonus round when the player has achieved a qualifying condition in the game. This qualifying condition can be a particular arrangement of one or more indicia on a display device. The gaming device 10 may use a video-based display device 30 to enable the player to play the bonus round. As illustrated in the five reel slot game shown in
As illustrated in
As further illustrated in
In operation, when a predetermined event occurs during a game, the processor implements the instructions of the game program and uses a random number generator or certain data stored in the data storage device to generate an outcome for a player. The outcome could be a randomly or predetermined award value or no value at all. The processor then uses the mechanical award indicator 102 to indicate the outcome to the player. The present invention thus provides a mechanical award indicator for indicating awards and particularly bonus awards to the player.
In one embodiment, the award indicator rotates all of the dice 106a to 106e. The award indicator stops the rotation of all of the dice, preferably in a sequential order and the dice display award values on their visible faces 110a to 110e. The gaming device provides the player with the sum of all of these award values, and the award indication process terminates.
In the example illustrated in
With continued reference to
In another embodiment illustrated in
After a predetermined event occurs in a game and the processor generates an outcome, the processor causes the award indicator 115 to rotate all of the dice. When the dice stop rotating, the visible faces 124a to 124e display either award values or multipliers. If the visible faces display only award values, the player receives the sum of all such award values. If, however, a multiplier 120a is displayed on one or more visible faces, the player receives: (a) the sum of all award values displayed on all of the visible faces multiplied by (b) the sum of all multipliers. In the example illustrated in
As illustrated in
In one example of this embodiment, when a predetermined event occurs during a game and the processor generates an outcome, initially die rotator 130e rotates die 132e. When die rotator 130e stops the rotation of die 132e, move indicator 134 is displayed on the visible face 136 of die 132e. The processor then causes the next higher die 132d to rotate. Die rotator 130d then rotates die 132d.
Each time a die rotator rotates and then stops rotating a die, the die's visible face will either display an award value, a move indicator or a terminator. As long as the player avoids move indicators and terminators, the die rotator will repeatedly rotate the same die, stop the die and display an award value. The player will receive all such award values. If the player reaches a move indicator, the next highest die will be rotated. This process continues until the player reaches the highest die 132a or a terminator symbol, whichever comes first.
In the example illustrated in
In one alternative embodiment, the move indicator indicates to a player a predetermined number of moves and a predetermined direction of movement. When a die displays such a move indicator to a player, the processor causes the die whose position is specified by the move indicator to move. For example, four dice could be aligned in a vertical formation, and a move indicator on a current die may display the message, “2 UP.” The processor would cause the rotation of the second die which is located above the current die.
In another alternative embodiment, the dice do not bear terminator symbols, but only bonus awards and move indicators. The player gains award values through repeated rotations of the same die until the player reaches a move indicator. Eventually, the player will reach the last die. When the last die displays a move indicator or another predetermined symbol, the award process of the gaming device terminates.
In another embodiment illustrated in
In operation of one example of this embodiment, a player spins the reels and a die symbol 158 appears on reel 34b on the payline 56. The processor automatically determines an outcome for the player. Then the processor causes the die rotator 152b, which is associated with reel 34b, to cause a predetermined rotation of die 154b. When die 154b stops the rotation, the player sees an award value of eighty credits on the visible face of the die 154b. The gaming device then terminates the award indication process and provides this award value to the player.
In one embodiment of the present invention, the gaming device enables a player to accept or reject certain outcomes or award values generated by the processor. The processor may generate an award value, use the award indicator to indicate the award value to the player and provide the player with the option of accepting or rejecting the award value. If the player accepts the award value, the award indication process terminates. If the player rejects the award value, the processor generates another award value, and the entire process repeats itself at least once.
It should be appreciated that although it is preferable that the processor causes all of the mechanical dice to rotate, in various embodiments the processor may only cause one or a select number of the dice to rotate. At that point, the gaming device will provide the player with the indicated award values.
In one embodiment of the present invention, the dice display points to the player in the form or numerals, dots or other symbols. When the dice stop rotating, the player receives a score which is preferably the sum of all points displayed on the visible faces of the dice. The storage device stores at least one table or scale which includes a plurality of score ranges. Each score range is associated with a predetermined award value. The score range within which a player falls, determines the award value which the player will receive.
For example, a gaming device may include: (a) a score range of zero to one hundred points associated with an award value of five hundred credits; (b) a score range of one hundred to three hundred points associated with an award value of one thousand credits; and (c) a score range of three hundred to one thousand points associated with an award value of three thousand credits. In operation, the processor may cause the dice to rotate. When the dice stop rotating, the visible faces of the dice will display predetermined points. If the sum of the displayed points is ten, the player receives five hundred credits, if the sum is two hundred, the player receives one thousand credits, and if the sum is three hundred fifty, the player receives three thousand credits.
In an alternative embodiment, the dice display award values. The gaming device includes a plurality of award ranges which define ranges for award values. Each award range is associated with a predetermined award value or award modifier. The award modifier includes any numerical factor or mathematical formula or function which modifies an award value. For example, an award range of zero to fifty credits can be associated with an award value of ten credits, an award value of fifty to one hundred credits can be associated with an award value of three hundred credits or an award value range of one hundred to four hundred credits can be associated with a modifier which is a multiplication factor of five. The gaming device can automatically provide the player with the award value associated with the award range reached by the player. Alternatively, the gaming device may enable the player to choose whether or not to accept the award values displayed on the dice or the award value associated with the award range reached by the player. In the case of the modifier, the gaming device applies the modifier to the award values displayed on the visible faces of the dice and calculates an award value. The gaming device may automatically provide this award value to the player or do so at the player's option.
In operation of this embodiment, the processor causes the dice to rotate. When the dice stop rotating, the visible faces of the dice will display predetermined award values. If the sum of the award values falls within a predetermined award range, the player receives the award value which is associated with that award range or which results from the modifier associated with that award range. The associated award value may be larger than, smaller than or the same as the sum of the displayed award values.
In another embodiment, one or more of the dice, such as die 118a, displays an award indicator, such as value 120, and an award modifier symbol, such as multiplier 120a. Although the award indicator is preferably a numerical value, the award indicator can include any symbol or image which indicates an award to a player. The award modifier symbol can include a multiplier, any other mathematical symbol or any other symbol which indicates a particular modification to or calculation of an award. For example, the award modifier symbol can be an image of an apple. The apple image can be associated with a mathematical function which multiplies all of the values displayed on the dice by three, or the apple image can be associated with a mathematical function with adds together all of the values displayed on the dice. It should also be appreciated that the award indicator and the award modifier symbol can be positioned on the same side of a die.
For example, one side of a die can include an award indicator, such as the numeral one-hundred, adjacent to an award modifier symbol, such as an image of a banana. The banana may be associated with a mathematical function which multiplies the adjacent award indicator by two. In one embodiment, if a plurality of dice simultaneously display a predetermined quantity of award modifier symbols, such as three bananas, the gaming device provides the player with a jackpot award or other predetermined award. The gaming device then terminates the game. It should be appreciated that this embodiment can include rotatable dice or any other suitable rotatable mechanical objects which have: (a) a plurality of axes of rotation; and/or (b) a plurality of relatively flat sides or faces.
In operation of one example of this embodiment, the cabinet or display device of the gaming device may display: (a) a strawberry associated with a multiplication function of four; and (b) three strawberries associated with a jackpot award value of two thousand. All of the dice on the gaming device may initially display an image or message to a player, such a “SPIN TO WIN.” Whether initiated by the gaming device processor or the player's input: (a) the first die may rotate and display a numerical value of fifty; (b) the second die may rotate and display a numerical value of twenty adjacent to a strawberry; (c) the third die may rotate and display a numerical value of one hundred; (d) the fourth die may rotate and display a value of two hundred; and (e) the fifth and final die may rotate and display a strawberry by itself. The player's award is calculated as follows: ((50+(20×3)+100+200)×3=1,230). The gaming device then provides this award to the player and terminates the game.
In another embodiment illustrated in
It is preferable that each of the mechanical objects 502 and 504a to 504c includes: (a) a pre-spin message or image 506, such as “SPIN!;” (b) at least one award indicator 508; and (c) at least one move indicator 510. The award indicator 508 is preferably a numerical value, though the award indicator 508 can be any symbol which indicates a particular value or award to the player. The move indicator 510 can include any suitable symbol, image or message which indicates which of the mechanical devices 502 will be rotated in sequence.
In one example of this embodiment, the grid 500 defines a plurality of sets, which in this example, are rows 512a, 512b and 512c. Each set or row is associated with a particular award level. Each award level is preferably the sum of all possible awards associated with the mechanical objects 502 in each of the rows 512a to 512c; or the likelihood or probability that the player will win a particular award by spinning the dice in each of the rows 512a to 512c. This award level preferably varies from row to row. In this example, the award level associated with the rows 512a to 512c increases from row 512a to row 512b to row 512c. Accordingly, as the player advances upward in the grid 500, the player's chances of gaining higher awards increases.
Referring to
It should be appreciated that the mechanical objects 502 can include various symbols associated with various predetermined events. For example, die 502f includes a terminating or termination symbol 514. If die 502f displays termination symbol 514 during the game, the game terminates. In another embodiment, the award indicators can function as terminators.
The die rotators of the gaming device of the present invention can include any suitable electrical and mechanical parts and devices which enable the gaming device to control the position of the mechanical dice. The gaming device indicates predetermined outcomes by stopping die rotation when predetermined visible faces are displayed to the player.
A predetermined outcome is associated with each face of each die. This information or dice data is stored in the data storage device. In the example illustrated in
For example, in one embodiment the processor may use a random number generator to generate an outcome of fifty credits and three hundred credits. Using the dice data, the processor may cause: (a) die one to rotate and display face six; and (b) die two to rotate and display face five. The player would then view fifty credits on die six and three hundred credits on die two, the sum of which is three hundred fifty credits.
In another example, the processor may use a random number generator to generate an outcome of one hundred credits. Using the dice data, the processor may cause die one to rotate and display face two, and the processor may simultaneously cause die two to rotate and display face three. The player would then view forty credits on die one and sixty credits on die two, the sum of which is one hundred credits.
From these examples, it should be understood that the gaming device of the present invention can generate separate, discrete outcomes or award values for predetermined die and then use such dice to indicated these outcomes. It should also be understood that the gaming device can generate a total award value for no particular die or dice and then select a dice or dice to indicate the total award value.
In one embodiment illustrated in
When the motor 170 operates, the drive shaft 172 spins, causing the rotation of optic encoder disk 173 and die holder 180. Die holder 180 rotates about an x-axis 196 defined by drive shaft 172. As the die holder 180 rotates, the gear set or gear assembly of the die rotator 160 cause the die 162 to rotate. Specifically, the front end of drive shaft 178 revolves around and engages fixed spur gear 176. This engagement causes spur gear 182 to rotate which, in turn, causes spur gear 186 to rotate. The rotation of spur gear 186 causes the rotation of shaft 188 and bevel gear 190. Bevel gear 190 engages bevel gear 192 which causes die 162 to rotate about a y-axis 198. The simultaneous rotation of die 162 about x-axis 196 and y-axis 198 causes the die 162 to rotate and eventually display all of its faces to the player.
In addition, shaft 188 is connected to a flag member 200. As shaft 188 rotates, so does flag member 200. A y-axis optical device 202 is connected to frame 168. Optical device or reader 202 includes a light emitting diode (LED) 204 spaced apart from a light sensor 206. In operation, LED 204 generates a light beam which is received by sensor 206. As shaft 188 rotates, flag member 200 periodically interrupts the light beam, generating light beam pulses. The gaming device processor reads the light beam pulses and converts them into machine-readable die control data or count data. This count data enables the processor to control and determine when each side of the die 162 has a visible position or is otherwise the visible face 164.
When the die rotator 160 is assembled, die 162 is mounted within die holder 180 so that face one of die 162 is the visible face 164 while flag member 200 is positioned between LED 204 and sensor 206. Accordingly, whenever flag member 200 blocks the light beam, a signal is produced which is associated with home data. The gaming device processor regularly checks for this home data to determine when face one of die 162 is the visible face or otherwise has a visible position.
The die rotator 160 further includes an x-axis optical device or reader 208 for tracking faces two through six of die 162. X-axis optical device or reader 208 is connected to mount 166. Optical device or reader 208 includes a light emitting diode (LED) 210 mounted on one side of the optic encoder disk 173 and a light sensor 212 mounted on the other side of the optic disk 173. As seen in
When die rotator 160 is assembled, the encoder disk 173 is adjusted so that slot 214 or 216 is aligned between LED 210 and sensor 212 when a full face of die 162 is the visible face 164. Accordingly, whenever a slot 214 or 216 enables the light beam to reach sensor 212, the gaming device processor is notified that a face is a visible face at that point in time.
By using the flag signal from optical device 202, the gaming device processor tracks whenever face one is a visible face 164. As such, optical device 202 or reader functions as a home sensor which notifies the gaming device processor when the die 162 is at a home position. By using the pulses from optical device or reader 208, the processor counts die faces two through six as they become visible faces.
For example, when the die 162 begins rotating, the flag member 200 may be between LED 204 and sensor 206 in which case the gaming device processor is notified that face one is the visible face. As the die rotates, the gaming device processor counts how many times a slot 214 or 216 passes between LED 210 and sensor 212. The total count is added to face one, resulting in face two, face three, face four, face five or face six reading. Each time flag member 200 passes between LED 204 and sensor 206, the gaming device processor resets this count to zero. If the die rotator begins rotating when a face other than face one is the visible face, the die rotator rotates the die a long enough time so that the flag member 200 passes between LED 204 and sensor 206 at least once. From that point forward, the gaming device processor can track and control whether the visible face is face one, face two, face three, face four, face five or face six.
It should be understood that optical device or reader 208 in conjunction with encoder disk 173 enable the die rotator to notify the gaming device processor of the die's visible face without relying upon calculations involving the type or speed of motor 170. Because the die holder 180 and encoder disk 173 are directly and rigidly connected to the motor shaft 172, the encoder disk 173 translates the operation of the motor (whether proper or improper) into accurate information about the position of the die 162. The die movement is thus directly and mechanically linked to the movement of the encoder disk. Therefore, the skipping of gears, variation in motor speed or motor malfunction will have less of an impact on producing erroneous die position information.
Though the die rotator of the present invention preferably includes an x-axis optical device and a y-axis optical device, it should be appreciated that the die rotator can include any suitable electromechanical motion detector, position tracking device or assembly, sensing device or sensing devices which, by communication with the gaming device processor, enables the gaming device processor to track and control which die face is a visible face at any one point in time. For example, the die rotator can include two optical devices or readers which co-act with rotating members coupled to the motor shaft. One of such members may be similar in construction to encoder disk 173 of die rotator 160. The other member is preferably engaged by one or more gears in order to cause a flag member or slot to align with the optical device only when a face one or home face of the die is the visible face. The gear ratio for such gearing preferably corresponds to the gear ratio of the gearing which translates the shaft motor rotation to rotation of the die about the y-axis.
It should also be appreciated that, instead of including flag member 200 and encoder disk 173, the present invention can include any suitable alternate members of any suitable shape or size. For example, an encoder disk with a single slot could be used instead of flag member 200. Also, a single blade could be use instead of encoder disk 173. In addition, an encoder disk with three slots or six slots could be used instead of encoder disk 173. Furthermore, the encoder disk can include slots or openings of any suitable size or shape.
As illustrated in
Die rotator 300 also includes a die rotator processor (not shown) which communicates with a die rotator memory device (not shown). The die rotator memory device stores one or more predetermined programs which direct the die rotator processor to control the illumination of the light sources or lamps 304. Preferably, the die rotator processor causes the lamps 304 to exhibit predetermined lighting displays, patterns and effects when predetermined events occur during the operation of the gaming device. For example when a die rotates, the die rotator processor preferably illuminates the lamps 304 surrounding that die.

In should also be appreciated that although the award indicator of the present invention preferably rotates mechanical dice, the award indicator can rotate other objects, such as wheels, balls or other suitable objects. For example, such objects can include multi-sided objects having more than six sides or less than six sides. These objects and the dice used in the present invention can include or incorporate structural modifications to or variations of the conventional dice. Such variations can include rounded edges, concave faces, convex faces and other structural changes.
The gaming device of the present invention includes an award indicator which enables the gaming device to rotate mechanical dice which bear award values. The gaming device uses the award indicator to provide predetermined award values to players. This type of gaming device increases the excitement and pleasure experienced by gaming device players.
It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
