Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • [0001]
    This application claims benefit of U.S. Provisional App. No. 61/034,684, filed Mar. 7, 2008, the entire contents of which are incorporated herein by reference.
  • BACKGROUND OF THE INVENTION

    The present invention relates to a gaming machine which rearranges peripheral symbols again around a predetermined display position.
  • [0004]
    2. Related Art
  • [0005]
    Conventionally, in slot machines, a game is started when a player bets a certain amount of credits. Then, a plurality of reels, on which a plurality of symbols is depicted, start to rotate, and is stopped after a predetermined time period elapses. As a result, an award is provided to the player based on a symbol combination which is displayed statically. U.S. Pat. No. 6,517,433 discloses that an award is provided corresponding to a predetermined number of symbols rearranged on a winning line.
  • [0006]
    However, in U.S. Pat. No. 6,517,433, when all the symbols are rearranged, an award corresponding to the symbols thus rearranged is provided. Therefore, once all the symbols are rearranged, even a part of the symbols is not rearranged again. Accordingly, once an award is settled, it will not be changed, and thus, a game tends to be monotonous.
  • [0007]
    The present invention provides a gaming machine with novel entertainment properties, which offers a probability of changing an award which is once settled by way of rearranging again a part of the symbols which were rearranged once.

    FIG. 6 is a flowchart showing a flow of processing operation in a first game of the gaming machine 13 executed by the game controller 100 of the gaming machine 13. The routine of FIG. 6 is a unit game.
  • [0061]
    It should be noted that the gaming machine 13 is activated in advance and the variables used in the CPU 106 on the game controller 100 are initialized to predetermined values, respectively, thereby providing normal operation of the gaming machine 13.
  • [0062]
    Firstly, the CPU 106 on the game controller 100 determines whether any credits remain, which correspond to the remaining amount of coins inserted by the player (Step S1). More specifically, the CPU 106 reads the amount of credits C stored in the RAM 110 and executes processing according to the amount of credits C. When the amount of credits C equals “0” (NO in Step S1), the CPU 106 terminates the routine without executing any processing, since it cannot start a game. When the amount of credits C is not less than “1” (YES in Step S1), the CPU 106 determines that coins remain as credits, and the CPU 106 moves the processing to Step S2.
  • [0063]
    In Step S2, the CPU 106 determines whether or not a pushing operation has been applied to the spin bet repeat switch 24. When the switch 24 has been pressed and the CPU 106 receives an operation signal from the switch 24 (YES in Step S2), the CPU 106 moves the processing to Step S13. On the other hand, when the CPU 106 does not receive the operation signal from the switch 24 after a predetermined period of time elapses (NO in Step S2), the CPU 106 determines that the switch 24 has not been pressed and moves the processing to Step S3.
  • [0064]
    In the following Step S3, the CPU 106 sets the game conditions. More specifically, the CPU 106 determines the number of coins bet in a unit game based on the operation of the bet switch 23. The CPU 106 receives the operation signals generated by the player operating the bet switch 23. Then, the CPU 106 stores the bet amount in a predetermined memory area of the RAM 110 based on the number of times the operation signals have been received. The CPU 106 reads the amount of credits C stored in a predetermined memory area of the RAM 110, and subtracts the abovementioned bet amount from the amount of credits C thus read. Then, the CPU 106 stores the subtracted value in a predetermined memory area of the RAM 110. Subsequently, the CPU 106 moves the processing to Step S4.
  • [0065]
    In the following Step S4, the CPU 106 determines whether the start switch 25 is ON, and then, waits for the start switch 35 to be operated. Upon the start switch 25 being operated, and accordingly, upon the operation signal being input from the start switch 25 (in a case of “YES” in the determination processing in Step S4), the CPU 106 determines that the start switch 25 has been operated and advances the processing to Step S5.
  • [0066]
    On the other hand, in Step S13, the CPU 106 determines whether the amount of credits C is at least the total bet number in a previous game. In other words, the CPU 106 determines whether it can start a game in response to a pushing operation applied to the spin repeat bet switch 24. More specifically, when the spin repeat bet switch 24 has been pushed, and the operation signal has been inputted to the CPU 106 from the spin repeat bet switch 24, the CPU 106 reads the credit amount C and the bet amount bet in the previous game, which are stored in RAM 110. Then, the CPU 106 determines whether or not the credit amount C is equal to or greater than the bet amount bet in the previous game based upon the relation between the credit amount C thus read and the bet amounts. The CPU 106 performs processing based upon the determination results. When the CPU 106 determines that the amount of credits C is less than the bet amount in the previous game (NO in Step S13), the CPU 106 terminates the present routine without any processing, since it cannot start a game. On the other hand, in a case where determination has been made that the aforementioned amount of credits C is at least the bet amount bet in the previous game (in a case of “YES” in Step S13), the CPU 106 subtracts the bet amount bet in the previous game from the aforementioned amount of credits C, and stores the subtracted value in a predetermined area of the RAM 110. Subsequently, the CPU 106 moves the processing to Step S5.
  • [0067]
    In the following Step S5, the CPU 106 performs rearranged symbol determination processing. A specific description is made below regarding the rearranged symbol determination processing.
  • [0068]
    First, the CPU 106 selects a random number in a range of values from 0 to 65535 for each of the nine reels by extracting a random number from the random generator 112. Next, the CPU 106 reads payout rate setting data from the ROM 108 to store thereof in the RAM 110, refers to symbol weighted data corresponding to the payout rate setting data, and determines symbols in the nine reels to be rearranged in each of the symbol display areas 81 to 89 based on the nine random numbers values thus selected. The CPU 106 determines symbols to be rearranged in the symbol display areas 81 to 89, thereby determining a winning combination. In the present embodiment, in a case where five or more identical symbols are rearranged in the symbol display areas 81 to 89, a winning combination corresponding to the rearranged symbols is achieved.
  • [0069]
    Upon determining a rearranged symbol, the CPU 106 determines whether at least a predetermined number of identical symbols (five symbols) for providing an award among nine symbols to be rearranged are rearranged or not. In a case where at least a predetermined number of identical symbols (five symbols) for providing an award among nine symbols to be rearranged are rearranged, the CPU 106 activates a flag indicating providing an award for generating an award corresponding to the predetermined number of identical symbols (five symbols) for providing an award. The activated flag, which indicates the player has won an award, is stored in a predetermined area of the RAM 110 according to the instruction from the CPU 106. On the other hand, in a case where at least a predetermined number of identical symbols (five symbols) for providing an award among nine symbols to be rearranged are not rearranged (a losing combination), the CPU 106 does not activate the flag indicating providing the award. Subsequently, the CPU 106 moves the processing to Step S6.
  • [0070]
    In the following Step S6, the CPU 106 instructs each of the nine video reels to start to rotate.
  • [0071]
    Upon displaying the image which shows each of the nine video reels starting to rotate, the CPU 106 waits for a predetermined period of time to elapse (Step S7). After the predetermined period of time has elapsed (in a case of “YES” in processing of Step S7), the CPU 106 instructs each of the nine video reels to stop rotating, thereby rearranging nine symbols (Step S8). Subsequently, the CPU 106 moves the processing to Step S9.
  • [0072]
    In the following Step S9, the CPU 106 determines whether the flag indicating that an award is provided, which is stored in a predetermined memory area in the RAM 110, is activated or not by means of the rearranged symbol determination processing in Step S5. In a case where the flag indicating that an award is provided is not activated (NO in the processing of Step S9), the CPU 106 terminates the present routine. On the other hand, in a case where the flag indicating that an award is provided is activated (YES in the processing of Step S9), the CPU 106 advances the processing to Step S10.
  • [0073]
    In the following Step S10, the CPU 106 determines whether the flag (a bonus flag) indicating switching to a bonus game, which is stored in a predetermined memory area in the RAM 110, is activated or not by the rearranged symbol determination processing in Step S5. More specifically, in a case where the flag indicating switching to a bonus game is activated (YES in the processing of Step S10), the CPU 106 advances the processing to Step S11. On the other hand, in a case where the flag indicating the switch to a bonus game is not activated (NO in the processing of Step S10), the CPU 106 advances the processing to Step S12.
  • [0074]
    In the following Step S11, the CPU 106 performs bonus game processing. More specifically, the CPU 106 starts a bonus game and performs a predetermined number of the bonus games. Subsequently, the CPU 106 terminates the routine.
  • [0075]
    In the following Step S12, the CPU 106 pays out the amount of coins corresponding to the number of the rearranged identical symbols which are at least a predetermined number (five symbols). Here, since WILD symbol is able to substitute for every symbol, the number of identical symbols includes the number of WILD symbols rearranged. More specifically, the CPU 106 refers to a payout table (not shown) and calculates the amount of coins corresponding to the number of the rearranged identical symbols which are at least a predetermined number (five symbols). The CPU 106 reads the credit amount stored in the aforementioned predetermined memory area of the RAM 110. Then, the CPU 106 calculates the sum total amount of coins to be paid out thus calculated and the credit amount thus read, and stores the sum thus calculated in a predetermined memory area of the RAM 110. The CPU 106 displays the aforementioned value thus stored on the credit amount display portion 49. The CPU 106 then moves the processing to Step S14.
  • [0076]
    In the following Step S14, the CPU 106 performs a second game processing and terminates the first game. The second game processing is described with reference to FIG. 7.
  • [0077]
    The second game processing is described below with reference to FIG. 7.
  • [0078]
    In Step S21 in FIG. 7, the CPU 106 first determines whether a WILD symbol has been rearranged at a center position (the symbol display area 85) or peripheral positions from the center position (any one of the symbol display areas 81 to 84 or the symbol display areas 86 to 89). In a case of a YES determination, the CPU 106 advances the processing to Step S22. In a case of a NO determination, the CPU 106 terminates the second processing.
  • [0079]
    In Step S22, the CPU 106 rearranges symbols again in a clockwise direction around the center position. More specifically, as illustrated later in FIG. 9, around the symbol display areas 85 as the center position, the symbol display area 89, which is positioned in a clockwise direction from the symbol display area 86 in which a WILD symbol was rearranged, is rearranged by the CPU 106.
  • [0080]
    During the abovementioned processing, the CPU 106 refers to a WILD symbol rearranging probability table (described later in FIG. 8) and determines whether to rearrange a WILD symbol in the symbol display area 89. Upon determining that a WILD symbol has been rearranged, the CPU rearranges a WILD symbol. On the other hand, upon not determining that a WILD symbol has been rearranged, the CPU rearranges any symbol other than a WILD symbol. The processing of Step S22 is performed repeatedly while a YES determination is made in the processing of Step S23 (while a WILD symbol is rearranged sequentially), and the CPU 106 determines whether a WILD symbol has been rearranged sequentially in the symbol display areas in the following order: 89, 88, 87, 84, 81, 82, and 83.
  • [0081]
    In Step S23, the CPU 106 determines whether the rearranged symbol is a WILD symbol or not. In a case of a YES determination, the CPU 106 advances the processing to Step S22. In a case of a NO determination, the CPU 106 advances the processing to Step S24.
  • [0082]
    In Step S24, the CPU 106 provides an award based on the WILD symbol thus rearranged. There are two ways of providing an award. One is a way of providing an award corresponding to the number of identical symbols rearranged in the symbol display areas 81 to 89, as described later in FIG. 11. The other one is a way of providing an award corresponding to identical symbols rearranged on the winning line L1 to L8, as illustrated later in FIG. 12.
  • [0083]
    A WILD symbol rearrangement probability table is described with reference to FIG. 8. The WILD symbol rearrangement probability table is a table to which the CPU 106 refers when determining whether to rearrange a WILD symbol in Step S22 of FIG. 7. For example, when the number of WILD symbols, which has been already rearranged, is two, the probability for rearranging a WILD symbol is determined to be “P1”. Here, the order is as follows: P1>P2>P3>P4>P5>P6>P7>0. Therefore, the larger the number of WILD symbols rearranged, the lower the probability for rearranging WILD symbol sequentially in a clockwise direction becomes.
  • [0084]
    FIG. 9 illustrates that a symbol once rearranged is rearranged again in a clockwise direction around the symbol display area 85. With reference to FIG. 9, a symbol is variably displayed in the symbol display area 89 adjacent consecutively with the symbol display area 86 in a clockwise direction at which a WILD symbol was rearranged.
  • [0085]
    FIG. 10 illustrates that a symbol is variably displayed in the symbol display area 88 adjacent consecutively with the symbol display area 89 in a clockwise direction upon a WILD symbol being rearranged in the symbol display area 89, and then, a symbol “K” is arranged in the symbol display area 88.
  • [0086]
    In this case, since a WILD symbol is not rearranged, a NO determination is made in the processing of Step S23 of FIG. 7 and an award is provided to a player.
  • [0087]
    FIG. 11 illustrates that the highest award is provided when the number of identical symbols rearranged in the symbol display areas 81 to 89 is at least five.
  • [0088]
    With reference to FIG. 11, assuming that the number of WILD symbols is included in the total number of identical symbols, there are five “7” symbols or five “Q” symbols. In the present embodiment, it is defined that the “7” symbol provides a greater award than the “Q” symbol. Therefore, a greater award corresponding to the “7” symbol is provided to a player. In addition, the present invention is not limited thereto, and awards corresponding to both the “7” symbol and the “Q” symbol may be provided to a player.
  • [0089]
    With reference to FIG. 11, a frame surrounding the symbol display areas 81, 82, 85, 86, and 89 is highlighted, which shows that an award corresponding to the “7” symbol is provided to a player.
  • [0090]
    FIG. 12 illustrates that awards corresponding to symbols rearranged on the winning lines L1, L3, L5, and L8 are provided to a player.
  • [0091]
    Here, the WILD symbol is able to substitute for any symbol. Therefore, it is assumed that, in FIG. 12, all of the symbols on the winning line L1 are “7” symbols, all of the symbols on the winning line L3 are “10” symbols, all of the symbols on the winning line L5 are “Q” symbols, and all of the symbols on the winning line L8 are “Q” symbols.
  • [0092]
    FIG. 13 shows a symbol display area arranged in a matrix of 5 rows by 5 columns. In a case of a matrix of 5 rows by 5 columns, similar to the symbol display areas 81 to 89 arranged in a matrix of 3 rows by 3 columns, a WILD symbol is rearranged in a clockwise direction (in a direction of an arrow 99) around the center symbol display area.
  • [0093]
    Since a part of symbols rearranged once is rearranged again by executing the second game, a player can expect a probability of changing the award which was once settled.
  • [0094]
    In addition, the player not only can feel suspense of winning as to how many times a WILD symbol is rearranged consecutively, but also can enjoy a game process in which a WILD symbol is rearranged sequentially in a clockwise direction in a square spiral pattern.
  • [0095]
    While an embodiment of the gaming machine according to the present invention has been described, it is to be understood that the above description is intended to be illustrative, and not limiting, and any changes in design may be made to specific configurations such as various means. Moreover, it should be understood that the advantages described in association with the embodiments are merely a listing of most preferred advantages, and that the advantages of the present invention are by no means restricted to those described in connection with the embodiments.
  • [0096]
    For example, although a WILD symbol is rearranged sequentially in a clockwise direction in the present embodiment, the present invention is not limited thereto. For example, a WILD symbol may be rearranged sequentially in a counterclockwise direction.
  • [0097]
    In addition, although the larger the number of WILD symbols rearranged, the lower the probability for rearranging WILD symbol sequentially in a clockwise direction becomes in the present embodiment, the present invention is not limited thereto. For example, the probability may be fixed constant or may be determined as appropriate regardless of the number of WILD symbols rearranged again.
  • [0098]
    In addition, although a second game is performed during a first game in the present embodiment, the present invention is not limited thereto, and the second game may be performed during a bonus game.
  • [0099]
    Furthermore, although in the present embodiment an example applied to a video reel slot machine is explained regarding the present invention, the present embodiment is not limited thereto, and for example, the present invention may be applied to a mechanical reel slot machine.
