Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • [0001]
    This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2003-412256, filed on Dec. 10, 2003 the entire contents of which are incorporated herein by reference.
  • BACKGROUND OF THE INVENTION
  • [0002]
    1. Field of the Invention
  • [0003]
    The present invention relates to a gaming machine on which card games such as blackjack and so on can be played with images of cards such as playing cards or the like being displayed on a screen, and a control method of the gaming machine.
  • [0004]
    2. Related Background Art
  • [0005]
    Conventionally, a gaming machine is known which displays images showing cards such as playing cards on its display screen, which is realized by a liquid crystal display panel or CRT, and changes the display of each of the card images in accordance with operation input by a player to thereby make the game progress (for example, Japanese Patent Unexamined Application No. 2001-70642, hereinafter, reference of “Patent Document 1”). A real player playing games on such a gaming machine plays playing-card games (card games) such as a blackjack game and a poker game against a dealer being a virtual opponent controlled by the gaming machine, and receives payout as a winning such as medals in accordance with the result of play.
  • SUMMARY OF THE INVENTION
  • [0006]
    The card game in the above-described conventional gaming machine including the above-described Patent Document 1, however, is that the win/loss is decided by comparing superiority/inferiority between a winning combination of cards of the real player and a winning combination of cards of the dealer being the virtual opponent controlled by the gaming machine, so that when the player wins, a fixed payout amount in accordance with the winning combination of the player is paid out. Therefore, in the card game performed in the conventional gaming machine, once the winning combination of the cards of the player is decided, the payout amount to be paid out when the player wins is automatically decided (known), thus giving the player repeatedly playing games on this gaming machine a feeling of monotony. Accordingly, the conventional gaming machine is not enough to keep the interest of the player.
  • [0007]
    The present invention has been developed in consideration of the above-described problems and an object thereof is to provide a gaming machine capable of keeping the interest of a player by making the contents of a card game varied and new, and a control method of the gaming machine.
  • [0008]
    To achieve the above-described object, the present invention is a gaming machine including a determining means determining establishment/non-establishment of a shift condition for shifting a game mode from a normal game mode to a special game mode and shifting means shifting the game mode from the normal game mode to the special game mode based on the determination result of the determining means, characterized by including: extraction means extracting a predetermined number of card data to be used in the special game mode, from a plurality of card data; selecting means selecting a card data to be assigned to the first group and card data to be assigned to each of a plurality of second group, from among the predetermined number of card data extracted by the extraction means; winning combination comparing means performing comparison between a winning combination based on the card data of the first group and winning combinations based on the card data of at least two the second groups; and payout calculating means calculating a payout based on the comparison result by the winning combination comparing means.
  • [0009]
    In the special game mode of the present invention, it is assumed there are a plurality of second groups, and winning combinations of the respective card data of the second group are compared to (played against) a winning combination of the card data of the first group to compete for superiority respectively. Therefore, a player of the first group is given a chance to receive a plurality of payout times by winning against the plurality of second groups. The payout amount (winnings) to be paid out to the first group is not defined until after the end of plays against all of the second groups even when the winning combination of the card data of the first group has been decided, thus allowing a player of the first group to continue having expectations till the last moment. Therefore, even if the game is repeatedly performed, the interest of a player of the first group can be kept.
  • [0010]
    In this case, it is preferable that the gaming machine further includes an instruction input device inputting instruction to the first group, wherein the selecting means selects the card data for the first group in accordance with the instruction inputted from the instruction input device. This allows the player of the first group to realize that his or her own will is reflected and he or she directly participates in the special game mode, so that the interest of a player of the first group can be kept longer.
  • [0011]
    Further, it is preferable that the payout changes in accordance with the number of the second group side against that the first group side has won. In this case, for example, when the payout is increased in proportion to the number of the second group side against that a player of the first group side has won, a player of the first group expects to win against the greater number of second groups, resulting in more interest added.
  • [0012]
    Further, it is preferable that, where processing from the extraction of the card data by the extraction means to the winning combination comparison by the winning combination comparing means is regarded as one game, a payout rate for calculating the payout by the payout calculating means is changed for each game. This allows a player of the first group to have expectations of winning of a game with a high payout rate, leading to more interest added.
  • [0013]
    Further, it is suitable that the gaming machine further includes a card display device displaying the card images using the card data selected by the selecting means.
  • [0014]
    Further, it is suitable that the selecting means select card data to be assigned to the first group as card data on a player side and select card data to be assigned to the second group as card data on the gaming machine.
  • [0015]
    Then, it is suitable that in the special game mode, a player is able to play a blackjack game.
  • [0016]
    The present invention provides a control method of a gaming machine including a determining means determining establishment/non-establishment of a shift condition for shifting a game mode from a normal game mode to a special game mode and shifting means shifting the game mode from the normal game mode to the special game mode based on the determination result of the determining means, the method including the step of: extracting a predetermined number of card data to be used in the special game mode, from a plurality of card data; selecting card data to be assigned to a first group and card data to be assigned to each of a plurality of second group, from among the predetermined number of extracted card data; performing a comparison between a winning combination based on the card data of the first group and winning combination based on the card data of at least two the second groups; and calculating a payout based on the comparison result of winning combination.

  • [0043]
    The touch panel 56 is provided in such a manner as to cover the display screen of the liquid crystal display panel 5 to detect the position of a place where a finger of the player touches and input into the main CPU 32 a position signal corresponding to the detected position. The lamp drive circuit 59 outputs to the lamp 60 a signal for turning on the lamp 60 to cause the lamp 60 to flash during execution of a game. With this flash, effective performance is realized. The LED drive circuit 61 controls flash display of the LED 62. The LED 62 performs credit-number display, acquired-coin number display, and so on. The hopper drive circuit 63 drives the hopper 64 under the control of the main CPU 32, and the hopper 64 performs operation for paying out coins for winning to pay out coins from the payout opening 13. The coin detector 66 counts the number of coins paid out by the hopper 64 and sends data on the counted number value to the payout completion signal circuit 65. The payout completion signal circuit 65 receives the data on the number value of coins from the coin detector 66 and inputs a signal notifying completion of the payout of coins into the main CPU 32 when the number value reaches data of the set number.
  • [0044]
    The image control circuit 71 controls image display on each of the liquid crystal display panels 3, 4, and 5 to cause the liquid crystal display panels 3, 4, and 5 to display various images such as the pseudo-reels which are variably displayed, card images, and the like.
  • [0045]
    The image control circuit 71 has, as shown in FIG. 3, an image control CPU 71 a, a work RAM 71 b, a program ROM 71 c, an image ROM 71 d, a video RAM 71 e, and a VDP (Video Display Processor) 71 f. The image control CPU 71 a decides the images (the pseudo-reels, card images, and so on) to be displayed on the liquid crystal display panels 3, 4, and 5 based on parameters set by the microcomputer 31 in accordance with an image control program (relating to the displays on the liquid crystal display panels 3, 4, and 5) stored in the program ROM 71 c in advance. The work RAM 71 b is constituted as a temporary memory when the image control CPU 71 a executes the image control program.
  • [0046]
    The program ROM 71 c stores the image control program, various selection tables, and so on. The image ROM 71 d stores dot data for forming images. The dot data includes, in this embodiment, image data not only on the pseudo-reels for use in the slot game in the first game but also on card images showing 52 playing cards (hereinafter referred to as a “card image group”) for use in blackjack. The video RAM 71 e is constituted as a temporary memory when the VDP 71 f forms images. The VDP 71 f having a control RAM 71 g forms images matching the display contents on the respective liquid crystal display panels 3, 4, and 5 decided by the image control CPU 71 a, and outputs the respective images formed to the liquid crystal display panels 3, 4, and 5.
  • [0047]
    Returning to FIG. 2, the sound control circuit 72 inputs into the speaker 73 a sound signal for outputting sound from the speaker 73. From the speaker 73, sound for making a game more exciting is outputted, for example, at an appropriate timing after start of the game.
  • [0048]
    Next, operation contents of the gaming machine 1 having the above-described configuration will be described with reference to flowcharts shown in FIG. 4 to FIG. 6 and FIG. 11. In the gaming machine 1, as shown in FIG. 4, the first game is executed first, and then the second game is executed under a certain condition. The first game is described as the slot game in the following illustration, but the first game executed in the game in the present invention is not limited to the slot game. The game may be, for example, a card game such as a poker game or the like. On the other hand, the second game only needs to be a card game in which the gaming machine side and the player play a match against each other, and is not limited to blackjack.
  • [0049]
    FIG. 4 is a flowchart showing the operation procedure of the main processing from the start to the end of a slot game in the gaming machine 1. Note that Step is abbreviated to S in FIG. 4 to FIG. 6 and FIG. 11. As shown in FIG. 4, the gaming machine 1 after starting the main processing performs start acceptance processing in Step 1 for starting a game.
  • [0050]
    In the start acceptance processing in Step 1, the gaming machine 1 accepts the operation for starting the game from the player under the control of the main CPU 32. To start the slot game to activate the pseudo-reels (to variably display the pseudo-reels), the player first inserts a number of coins to be bet in one game through the coin insertion slot 6 and operates the BET selection button 9 to thereby decide the number of coins to be bet in one game. Further, the player operates the line selection button 10 to select an effective line. Subsequently, the player operates the spin button 8 (hereinafter a series of these operations is referred to as “start operation”). With this start operation, a start signal is inputted from the start switch 51 into the main CPU 32 (in the case of credit, a BET selection signal is inputted from the BET switch 52).
  • [0051]
    Then, the processing proceeds to Step 2, in which lottery processing in the first game is performed. When the lottery processing is started, the processing proceeds to Step 13 shown in FIG. 5, in which the main CPU 32 performs symbol decision processing. In this symbol decision processing, the main CPU 32 decides a symbol to be stopped on a selected effective line L for each pseudo-reel.
  • [0052]
    Further, in the lottery processing, when detecting the start operation of the player based on the input signal from the start switch 51, the main CPU 32 instruct the random number generator 35 to generate random numbers within a certain range upon receipt of the detection (in other words, regarding the start of the game as a trigger). The main CPU 32 further instructs the sampling circuit 36 to extract an arbitrary random number from the random numbers generated by the random number generator 35. When the random number is extracted, the main CPU 32 sets the random number in a search key to acquire the code No. of its corresponding symbol and the symbol, referring to symbol decision tables 81 to 83 shown in FIGS. 7(a) to (c) stored in the ROM 34. The symbol decision tables 81 to 83 shown in FIGS. 7(a) to (c), which correspond to the pseudo-reels R1 to R3 in order, are tables storing the code No. of each symbol and the symbol associated with the random numbers. For example, when the random number extracted by the sampling circuit 36 is a number ranging from 0 to 20, the code No. “0” and the symbol “(WILD)” are acquired. The processing of extracting a random number to acquire its code No. is performed for each of the pseudo-reels R1 to R3.
  • [0053]
    Alternatively, it is suitable to search a corresponding symbol for each of the pseudo-reels R1 to R3 referring to one stop table 90 as shown in FIG. 8, instead of the three symbol decision tables 81 to 83.
  • [0054]
    Here the stop table 90 is, as shown in FIG. 8, a table having a code No. area 90 a where code Nos. (of symbols) are stored, a symbol area 90 b where the symbols corresponding to the code Nos. are stored, and a random number area 90 c where random numbers are stored, and is configured such that when a random number is set in the search key to search the random number area 90 c, the code No. of its corresponding symbol and the symbol can be searched for each of the pseudo-reels R1 to R3. In the symbol area 90 b, symbols are registered corresponding to the code Nos. of “0” to “6” for each of the pseudo-reels (the order of the registered symbols is different from those of the symbol decision tables 81 to 83 shown in FIG. 7). For example, C1 shown in FIG. 8 shows a symbol pattern composed of symbols when the acquired code Nos. are “0” for all of the pseudo-reels R1 to R3.
  • [0055]
    Then, in the gaming machine 1, the extraction of a random number and the search of the symbol decision tables 81 to 83 or the stop table 90 are performed for each of the pseudo-reels R1 to R3. When symbols are decided for the pseudo-reels R1 to R3, stop positions of the reels for stopping the symbols on the effective line L are then decided.
  • [0056]
    Referring again to FIG. 5, upon decision of the stop positions of the reels, the main CPU 32 proceeds to Step 14 and determines winning/non-winning referring to a winning determination table 86 stored in the ROM 34. Here in the winning determination table 86, as shown in FIG. 9, either of a winning symbol pattern and a not-winning (non-winning) symbol pattern is distinguishably registered associated with the combination of the code Nos. (hereinafter referred to as a “code No. pattern”). Since the code No. pattern corresponding to the stop positions of the pseudo-reels is decided in Step 13, the main CPU 32 sets the code No. pattern in the search key and refers to the winning determination table 86, thereby determining winning/non-winning from the reference result. Note that, in the winning determination table 86, code No. patterns are set corresponding to the stop table 90.
  • [0057]
    Subsequently, the main CPU 32 refers to a contents table 91 shown in FIG. 10 and performs a winning contents determination processing of determining the winning contents (the “winning contents” is referred to also as a “winning combination”). Here the contents table 91 is for deciding the contents in winning (winning state), in which payout amounts (the payout of coins and the contents of the second game) corresponding to the winning contents are registered as shown in FIG. 10. For example, a winning combination “(any)-(any)-trigger-1 or 2” means a case when specific symbols (symbols when the code No. of the pseudo-reel R3 is 2 or 6, and the code Nos. of the pseudo-reels R1 and R2 are arbitrary numbers) appear, so that BONUS 1 or 2 here, that is, the second game is executed. Note that the difference between BONUS 1 and BONUS 2, described later in detail, is in that the number of opponents in the second game is different. Besides, a winning combination “7-7-7” means that the symbols on the pseudo-reels R1 to R3 match to “7,” in which case the payout amount is 80 coins. With that the lottery processing ends.
  • [0058]
    Next, the processing proceeds to Step 3, the first game processing is performed. The first game processing is performed with the game mode is kept in the normal game mode and includes Step 17 to Step 19 shown in FIG. 6. In Step 17, variable display processing is performed. In this case, the image control circuit 71 operates according to the instruction of the main CPU 32 to display, for example as shown in FIG. 11, a game execution image including variable display images of the plurality of pseudo-reels R1 to R3 is displayed on the liquid crystal display panel 5. FIG. 11 is a view showing the game execution image in the normal game mode on the liquid crystal display panel 5. On the liquid crystal display panel 5, the three pseudo-reels R1, R2, and R3 are variably displayed at the center thereof, and the laterally extending straight effective line L is displayed at the middle thereof. Each of the pseudo-reels R1 to R3 has a plurality of symbols (for example, a symbol S1 displaying “WILD,” a symbol S2 displaying “BONUS 1,” and so on) and is thus variably displayed such that the symbols appear successively in an irregular order. Note that the “BONUS 1” of the symbol S2 shown in FIG. 11 corresponds to the “trigger 1” shown in FIG. 10. Further, in the gaming machine 1, the three pseudo-reels are arranged side by side in a line in the horizontal direction, but the number of reels is not limited to three. For example, the number may be five or nine.

    Further, in a region E1 on the upper right side of the pseudo-reels R1 to R3, the credit number and the BET number are displayed. Furthermore, in a region E2 on the lower side of the pseudo-reels R1 to R3, explanation of the game contents (in this embodiment, characters “INSERT COIN PUSH THE BUTTON”) is displayed.
  • [0060]
    Though not shown, the main CPU 32 instructs, during the first game processing, the image control circuit 71 to display the payout table and the three-dimensional images for game performance on the liquid crystal display panel 3 and the image for explanation of how to play games and the like on the liquid crystal display panel 4.
  • [0061]
    Referring again to FIG. 6, after the end of Step 17, the processing proceeds to Step 18, in which stop control processing is performed. Here the pseudo-reels R1 to R3 in scrolling are stopped to correspond to the result of the lottery processing in Step 2.
  • [0062]
    Next, the processing proceeds to Step 19, in which payout processing is performed. In this case, when the main CPU 32 instructs the hopper drive circuit 63 to perform payout of a number of coins corresponding to the search result in the contents table 91, the hopper 64 performs payout of coins in the first game. Further, when determining that the payout of the instructed number of coins by the signal from the payout completion circuit 65 has been performed, the main CPU 32 ends the payout processing and proceeds to Step 4 shown in FIG. 4.
  • [0063]
    After proceeding to Step 4, the main CPU 32 operates as a determining means to determine whether the trigger for shifting to the second game is established or not (establishment/non-establishment of a shift condition for shifting the game mode from the normal game mode to the special game mode) from the result of the winning contents determination in Step 14. Here when the winning contents shows the possibility of shifting to the special game mode (for example, when the symbol pattern is “(any)-(any)-trigger 1 or 2” shown by B1 or B2 in FIG. 10), the main CPU 32 operates as shifting means and proceeds from Step 4 to Step 5 to shift the game mode to the special game mode, thereby performing the second game processing. If the shift condition is not established, the main CPU 32 ends the main processing without executing Step 5.
  • [0064]
    Next, the second game processing being a characteristic part of the present invention will be described.
  • [0065]
    In the second game processing in this embodiment, a game (card game) in which a first player (card assigned to first player is referred to as first group) plays against a plurality of second players (card assigned to second player is referred to as second group) can be performed. In this card game, the processing is performed with the first player standing on a position of a player really existing (hereinafter, referred to as a real player) and each of the second players standing on a position of a virtual player (hereinafter, referred to as a virtual player) on the main CPU (gaming machine) side. Further, the first player plays a role as a master (dealer) and the second players play roles as slaves, and the first player and the plurality of second players play a match on blackjack. In short, the real player plays against the plurality of virtual players.
  • [0066]
    After the processing proceeds to Step 5 shown in FIG. 4 and the second game is started, the processing proceeds to Step 20 shown in FIG. 12 in which the main CPU 32 operates as an extraction means to extract image data for a predetermined number of card images of cards to be used in the second game (image data for a card image is referred to as “card data”.). Note that, in addition to image data, number on the card, mark on the card, and so on, information for specifying each of the card image are included in card data. In this event, the main CPU 32 extracts from the card image group the card data for displaying the predetermined number of cards on the liquid crystal display panel 5, referring to data obtained from the sampling circuit 36. In the second game, the liquid crystal display panel 5 operates as a card display device in the present invention. In this embodiment, the card data for displaying respective cards of the real player as the master and the virtual players as the slaves are extracted. In this event, the number of virtual players as the slaves is decided from the result of the above-described winning contents determination in Step 14. For example, when the result is “BONUS 1” (the symbol pattern is “(any)-(any)-trigger 1”), the number of the virtual players is decided to be three, and when the result is “BONUS 2” (the symbol pattern is “(any)-(any)-trigger 2”), the number of the virtual players is decided to be five. Note that, in the embodiment described below, the case of “BONUS 1,” that is, the case in which the virtual player are three will be described.
  • [0067]
    Next, the processing proceeds to Step 21, in which cards are distributed to the real player and the virtual players, respectively. In more detail, the main CPU 32 operates as a selecting means to select card data which is assigned to the real player and is to be displayed as the card for the real player, from the card data extracted in Step 20. On the other hand, the main CPU 32, which also operates as a decision means deciding the card images to be assigned to the virtual players respectively, selects card data which are assigned to the virtual players and are to be displayed as cards for the virtual players, from the card data extracted in Step 20. Then, after the selection, the main CPU 32 causes the liquid crystal display panel 5 to display the card images using the selected card data. In this event, first of all, the main CPU 32 displays on the liquid crystal display panel 5 such that cards facing up are distributed to the real player and all of the virtual players, one for each.
  • [0068]
    FIG. 13 is a schematic view showing a state in which card images for the real player and the virtual players are displayed, one for each. In this drawing, a card image 40 a (“A” here) for the real player is displayed on the left side as the player faces, on the liquid crystal display 5, and card images 41 a (“7” here), 42 a (“8” here), and 43 a (“A” here) for the virtual players are displayed on the right side as the player faces, on the liquid crystal display 5. Further, at the lower right side on the liquid crystal display panel 5, the number of games (three games here) that the real player has won until then, regarding processing from Step 20 to later-described Step 26 as one game, and the number of coins to be an object of BET selected and set by the real player (10 here) are displayed.
  • [0069]
    Next, the main CPU 32 operates as a selecting means to select card data for newly displaying as the cards for the real player and the virtual players, from the card data extracted in Step 20, and causes the liquid crystal display panel 5 to display the card images using the card data. In this event, the main CPU 32 displays a card image 40 b such that a card facing down is distributed to the real player and displays card images 41 b, 42 b, and 43 b such that cards facing up are distributed to the virtual players, one for each. It is only required that the numbers on all of the card images to be distributed have been decided at this point of time, and various timings are conceivable as the timing of deciding the numbers on all of the card images. Thereafter, the card image 40 b (“9” here) for the real player facing down is turned up.
  • [0070]
    FIG. 14 is a schematic view showing a state in which card images for the real player and for the virtual players are displayed facing up, two for each. At this point of time, winning combinations based on the card data corresponding to the card images of the real player and the virtual players may be decided. In this case, the processing proceeds to Step 23, in which the main CPU 32 operates as winning combination comparing means to perform a winning combination comparison in which the winning combination based on the card data corresponding to card images 40 a and 40 b of the real player is compared with the winning combinations based on the card data respectively corresponding to the card images 41 a and 41 b, the card images 42 a and 42 b, and the card images 43 a and 43 b of the virtual players, using the number on the card, mark on the card for specifying each of the card images(in this embodiment, the number on the card), out of card data corresponding to the respective card images of the real player being the master and the virtual players being the slaves. Note that the “winning combination” mentioned here is not the “winning contents” in the above-described first game but means the combination of the numbers on the plurality of card images. Then, the processing proceeds to Step 24, the main CPU 32 compares superiority/inferiority between the winning combination of the card images of the real player and the winning combination of the card images of the virtual player to determine whether the real player wins or not. More specifically, the main CPU 32 compares the total of the numbers on the card images of the real player with the total of the numbers on the card images of the virtual player to determine which is closer to “21.”
  • [0071]
    It is assumed that comparison with the virtual player corresponding to the card images 41 a and 41 b shown in FIG. 14 is performed first of all. Since the total of the numbers on the card images of this virtual player is 10+7=17, while the total of the numbers on the card images of the real player is 9+11 (A is assumed to be 11)=20, the real player is determined to win. Then, the processing proceeds to Step 25, in which a payout amount to be paid to the real player is added. Next, the processing proceeds to Step 26, the main CPU 32 operates as a determining means to determines whether or not the winning combination of the card images of the real player have been compared to the winning combinations of the card-images of all of the virtual players (whether or not the winning combination comparison has been performed for the card images of all of the virtual players).
  • [0072]
    In Step 26, when it is determined that the winning combination of the card images of the real player has not been compared to the winning combinations of the card images of all of the virtual players, the processing returns to Step 23, and when it is determined that the winning combination of the card images of the real player has been compared to the winning combinations of the card images of all of the virtual players, the processing proceeds to Step 27. Thus, the main CPU 32 repeats the processing from Step 23 to Step 25 until the winning combination of the card images of the real player is compared to the winning combinations of the card images of all of the virtual players. In the state shown in FIG. 14, the totals of the numbers on the card images of the virtual players are 10+7=17, 9+8=17, and 10+11 =21, respectively. Accordingly, comparing the totals of the numbers on the card images of the real player and the virtual players, the real player has won against two virtual players, so that “WIN×2” is displayed at the upper side on the liquid crystal display panel 5, and “WON 4” is displayed at the lower right side on the liquid crystal display panel 5 since the number of games that the real player has won until then is increased by one. On the other hand, in Step 24, when the real player has not won against the virtual players, the main CPU 32 proceeds to Step 26 without executing Step 25 and performs the determination similar to the above.
  • [0073]
    In Step 26, when it is determined that the winning combination of the card images of the real player has been compared to the winning combinations of the card images of all of the virtual players, the processing proceeds to Step 27, in which it is determined, regarding the processing from Step 20 to Step 26 as one game, whether or not the game has been executed a predetermined number of times (for example, seven times), and if executed, the processing proceeds to Step 28 and if not executed, the processing returns to Step 20. For returning to Step 20, the main CPU 32 instruct the image control circuit 71 to delete the cards already displayed on the liquid crystal display panel 5, and to extract predetermined number of card data again in a manner similar to the above. In this case, for example, Step 29 is provided between Steps 26 and 27 as shown in FIG. 15, and count-up in which “1” is added to the game number counter is performed in Step 29. Further, in Step 27, whether or not a predetermined number of games have been completed may be determined depending on whether or not the game number counter indicates the predetermined number or greater in Step 27 (the game number counter is cleared after Step 28).
  • [0074]
    In Step 28, the main CPU 32 operates as payout calculating means to calculate the payout for a winning corresponding to the comparison result of the winning combination of the card images in Step 23. Further, the main CPU 32 instructs the hopper drive circuit 63 to perform payout corresponding to the calculated payout. Then, upon receipt of the instruction, the hopper drive circuit 63 issues an instruction of payout of the payout of coins, so that the hopper 64 pays out coins. Here the main CPU 32 operating as the payout calculating means calculates the payout using a payout being a reference which is set separately from that for the first game. In this event, the payout changes in accordance with the number of virtual players against that the real player has won as a result of comparison between the winning combinations of the card images, for example, increases in proportion to the number of virtual players against that the real player has won. In this case, there is a possibility that the greater the number of virtual players playing against the real player, the larger the payout becomes, and therefore the real player expects that the symbol patter becomes “BONUS 2” (a symbol pattern of “(any)-(any)-trigger 2”) for five virtual players rather than “BONUS 1” (a symbol patter of “(any)-(any)-trigger 1”) for three virtual players in the above-described first game. Consequently, the first game is made more attractive. With that the second game ends.
  • [0075]
    In the above-described second game, though the winning combinations of the card images of the real player and the virtual players are decided at the point of time when two card images are distributed to each of them as shown in FIG. 14, it is also suitable to further select card data so that the totals of the numbers on the card images of the real player and the virtual players to be “21” or less in conformity with the rule of normal blackjack. In this case, the main CPU 32 may perform all of selections of the card data so as to progress the game automatically, or the main CPU 32 as a selecting means may select, for the card images of the real player, the card data one by one in response to the instruction of the real player inputted from the liquid crystal display panel 5 as an instruction input device. In this event, the main CPU 32 causes the liquid crystal display panel 5 covered with the touch panel 56 to display, for example, “HIT” and “STAND.”
  • [0076]
    Then, for example, when the real player touches “HIT,” card data for one card is selected and a card image is displayed using the card data on the liquid crystal display panel 5. The selection of card images by touching “HIT” can be performed any times unless the total of the numbers on the card images of the real player exceeds “21.” On the other hand, when the real player touches “STAND,” a winning combination is decided by the card images being displayed on the liquid crystal display panel 5 at the point of time. Note that, when the total of the numbers on the card images exceeds “21,” it is regarded as a burst, so that a loss is decided at that point of time. Note that it is also suitable that buttons for inputting instructions “HIT” and “STAND” are provided on the cabinet 2 so that the real player pushes the buttons to select “HIT” and “STAND.”
  • [0077]
    Besides, although the number of virtual players in the second game is decided to be three or five based on the result of winning contents determination in the above-described Step 14 in this embodiment, it is also suitable that the number of virtual players can be freely set by the real player inputting an instruction from the liquid crystal display panel 5 as an instruction input device. In this case, the designation of the number of virtual players is performed prior to, for example, Step 20. Such a free selection of the number of virtual players allows the estimated payout amount to be great changed, thereby making the game contents more interesting.
  • [0078]
    As described above, according to the present invention, processing is performed with the first player standing on a position of a real player and each of the second players standing on a position of a virtual player, in which the real player thus plays against a plurality of opponents. This allows the real player to win a plurality of times in one game and obtain accordingly increased payout amount. Further, the payout amount to be paid to the real player is not defined until after plays against all of the virtual players are finished, which allows the real player to keep an expectation to the last moment of the game. Therefore, even when play of a game is repeatedly performed on the gaming machine 1, the payout amount to be paid for a win is not fixed but changes in each play of the game, which can keep the interest of the real player.
  • [0079]
    In the above-described second game of the gaming machine 1, the game can be repeatedly performed a plurality of times, and in this event the payout rate may be changed for each game. For example, the number of games is counted by the main CPU 32 so that the payout being a reference for payout set in accordance with the winning combination of the card images may be multiplied by a multiplier in accordance with the number of games (this multiplier is for calculating the payout and referred to as a “payout rate” hereinafter). For example, in the case of the total number of games is 7, when the number of games is 1 to 6 (a first game to a sixth game), the payout rate can be 1, and when the number of games is 7 (a seventh game), the payout rate can be 2. This can make the real player losing at the beginning expect to recover the loss if he or she wins in the last game, thus making the game more attractive.
  • [0080]
    Based on the foregoing, the payout (payout amount) in the second game can be calculated also by the following Equation 1. It should be noted that Equation 1 is an example, and the calculation equation for the payout in the second game, as a matter of course, is not limited to this.
    Payout amount H=(BET number+X )×S+  Equation 1:
  • [0081]
    X: payout amount when winning against one slave, S: payout rate in each game
  • [0082]
    In Equation 1, assuming that the BET number is 10, the payout amount when winning against one slave is five coins, the payout rates in the first to third games are 1, 2, and 3 respectively, and the numbers of slaves against that the master has won in the first to third games are two, one, and two respectively, the payout amount H is:
    H=(10+5+5)×1+(10+5)×2+(10+5+5) ×3=110 (coins).
  • [0083]
    In the foregoing, the present invention has been described concretely based on the embodiments, but the present invention is not limited to the above-described embodiments. For example, the second game is started after the end of the first game in the above-described embodiments, but may be started during play of the first game. Besides, the number of slaves (virtual players) may be decided by lottery under the control of the main CPU 32.
  • [0084]
    Further, in the second game processing in this embodiment, the real player plays a role as a master and the virtual players play roles as slaves, it is suitable that the real player plays a role as slave by a selection of real player. It is suitable that the real player select a role as slaves at any time. If the real player plays a role as a slave by the selection of real player, the real player players a plurality of role as slave against the virtual player.
  • [0085]
    According to the present invention, processing is performed with the first player standing on a position of the real player and each of the second players standing on a position of a virtual player. Further, when a plurality of second players playing against the first player appear on the game and the first player has played against all of the second players, the payout amount to be paid to the first player is decided in accordance with the play against each of the second players. This can keep the interest of the first player.
  • [0086]
    It is apparent that various embodiments and modifications of the present invention can be embodied, based on the above description. Accordingly, it is possible to carry out the present invention in the other modes than the above best mode, within the following scope of claims and the scope of equivalents.
