  • DETAILED DESCRIPTION OF THE EMBODIMENT First Embodiment
  • FIG. 1 is a flow chart schematically showing a playing method of a slot machine according to the first embodiment of the present invention. In the following, the schematic operations in the slot machine and the playing method according to the first embodiment of the present invention will be described with references to the flow chart shown in FIG. 1 and a diagram shown in FIG. 2.
  • In the slot machine according to the first embodiment of the present invention, when the power is turned on and the slot machine is activated, an authentication processing is carried out first (step S100). In this authentication processing, the initial checking processing at a preliminary stage before starting a unit game, such as whether a program for operating the system is operating normally or not, whether there is any falsification of a program or not, etc., is carried out.
  • Next, a base game is executed (step S200). In this base game, when a spin button 23 is pressed in a state where a desired credit amount is bet by entering coins into a coin slot 21 or the like, a unit game in which the scrolling of a symbol in each first display region 28 (28 a to 28 e) of a liquid crystal display 17 a provided inside a display window 15 which is provided on a front face of a cabinet 11 is started and then the scrolling is stopped and the symbol in each first display region 28 is stopped (rearranged) is executed. Namely, in the base game, the unit games for five columns will be executed.
  • In each unit game, a processing for determining a symbol to be stopped in each first display region 28 (28 a to 28 e) is carried out, and whether a winning combination associated with a payout is stopped on a payline L1 that is set as a horizontal line at a middle level of each first display region 28 or not, that is, whether the winning combination is realized or not, is judged (step S300). Here, in the case where the winning combination is realized, a transition to another game or a payout is made according to a first payout table (step S400). For example, in the case where symbols “APPLE” are stopped on the payline L1, a transition to a bonus game is made according to the first payout table. In the case where symbols “CHERRY” are stopped on the payline L1, a payout of 20 coins is made according to the first payout table.
  • In the case where a predetermined condition is realized, such as the case where the winning combination is not realized, at the step S200, a sub game for rearranging symbols according to prescribed rules is executed (step S500). When the sub game is started, the symbols are rearranged according to a tag information set in correspondence to each symbol and a predetermined tag arrangement at the first display regions 28 (28 a to 28 e). The symbols rearranged by this sub game are displayed in second display regions 48 (48 a to 48 e) of the liquid crystal display 17 b provided inside a display window 14 which is provided on a front face of the cabinet 11. Then, whether a winning combination associated with a payout is stopped on a payline L2 that is set as a horizontal line at a middle level of each second display region 48 (48 a to 48 e) or not, that is, whether the winning combination is realized or not, is judged (step S600). Here, in the case where the winning combination is realized, a payout is made according to a second payout table (step S700). For example, in the case where symbols “PLUM” are stopped on the payline L2, a payout of 5 coins is made according to the second payout table. In the sub game, the scrolling of the symbols is not carried out, but the rearranged symbols will be described as “stopped” for the sake of convenience in this first embodiment.
  • As such, in the case where the winning combination is not realized at the step S200, the sub game for rearranging symbols according to prescribed rules is executed. Then, in the case where the winning combination is realized, a payout is made. In this way, the player is given a chance to obtain a prize in a subsequent sub game even when a prize cannot be obtained by the initial base game, so that it is possible to make the player to continually maintain interest in the game.
  • In the above described example, an exemplary case of stopping and displaying symbols in the first display regions 28 (28 a to 28 e) has been described, but the present invention is not limited to the first display regions 28 of three rows by five columns. Similarly, an exemplary case of rearranging and displaying symbols in the second display regions 48 (48 a to 48 e) has been described, but the present invention is not limited to the second display regions 48 of three rows and five columns.
  • In the above described example, an exemplary case of displaying symbols in the first display regions 28 by using the liquid crystal display 17 a has been described, but it is also possible to use a configuration using mechanical rotation reels in cylindrical shapes having a plurality of symbols displayed on their side faces, in which the rotation reels are rotated and then stopped such that the symbols are stopped inside the display window 15. Similarly, an exemplary case of displaying symbols in the second display regions 48 by using the liquid crystal display 17 b has been described, but it is also possible to use a configuration using mechanical rotation reels in cylindrical shapes having a plurality of symbols displayed on their side faces, in which the rotation reels are rotated and then stopped such that the symbols are rearranged inside the display window 14.
  • In the above described example, an exemplary case of executing the sub game in the case where the winning combination is not realized in the base game has been described, but it is also possible to execute the sub game only in the case where the winning combination is realized in the base game. It is also possible to execute the sub game regardless of whether the winning combination is realized in the base game or not, and it is also possible to determine whether a transition to the sub game is to be made or not, randomly, after the symbols are rearranged by the base game.
  • Next, a configuration of the slot machine 10 according to the first embodiment of the present invention will be described with reference to a diagram shown in FIG. 2 and a diagram of the second display regions shown in FIG. 3. The slot machine 10 is provided within a gaming facility.
  • In the slot machine 10, the coins, bills or electronic value information corresponding to these will be used as the game medium for executing the unit game. However, the game medium that can be used in the present invention is not limited to these, and can be medals, tokens, electronic money, or tickets, for example. The tickets are not limited to any particular tickets and can be tickets with bar codes, for example, as will be described below.
  • As shown in FIG. 2, the slot machine 10 has a cabinet 11, a top box 12 provided on an upper side of the cabinet 11, and a main door 13 provided on a front side of the cabinet 11.
  • Inside the cabinet 11, a liquid crystal display 17 a for scrolling symbols of three rows by five columns inside the display window 15 and a liquid crystal display 17 b for scrolling symbols of three rows by five columns inside the display window 14 are provided as a display. The liquid crystal display 17 a has the first display regions 28 (28 a to 28 e) for displaying symbols of three rows by five columns. The liquid crystal display 17 a has the second display regions 48 (48 a to 48 e) for displaying symbols of three rows by five columns.
  • When the base game is executed, the symbol sequence is scrolled in each of the first display regions 28 (28 a to 28 e) of three rows by five columns. As a result, it becomes possible for the player to see the scrolled symbols through the display window 15.
  • On the upper right side of the first display regions 28, the second display regions 48 (48 a to 48 e) for displaying symbols rearranged by the sub game to be described below are provided. FIG. 3 shows the second display regions 48. When the sub game is executed, the symbols are rearranged in the second display regions 48 (48 a to 48 e) of three rows by five columns. As a result, it becomes possible for the player to see the rearranged symbols through the display window 14, as shown in FIG. 3. In the second display regions 48 (48 a to 48 e), the symbols of the same design as the symbols displayed in the first display regions 28 (28 a to 28 e) are displayed.
  • The display is not limited to an example of the first embodiment. For example, it is also possible to display symbols through the display windows 14 and 15 by rotating and then stopping mechanical reels displaying symbols on their side faces. The first display regions 28 and the second display regions 48 are not limited to be those of three rows by five columns.
  • On a front side of the liquid crystal displays 17 a and 17 b in the main door 13, a lower side image display panel 16 is provided. The lower side image display panel 16 has a transparent liquid crystal panel, on which various information regarding the game and the effect images will be displayed during the game.
  • On the lower side image display panel 16, a credit amount display unit 31 and a payout amount display unit 32 are provided. On the credit amount display unit 31, the number of coins credited is displayed by an image. On the payout amount display unit 32, the number of coins to be paid in the case where a combination of symbols that are stopped on the payline L1 or L2 is the winning combination as will be described below is displayed by an image.
  • On the lower side image display panel 16, the display window 15 through which symbols displayed in the first display regions 28 (28 a to 28 e) of the liquid crystal display 17 a provided inside the cabinet 11 are visible and the display window 14 through which symbols displayed in the second display regions 48 (48 a to 48 e) of the liquid crystal display 17 b provided inside the cabinet 11 are provided.
  • On a horizontal line at a middle level of the first display regions 28 (28 a to 28 e), a single payline L1 is set horizontally across the first display regions 28 (28 a to 28 e). Similarly, on a horizontal line at a middle level of the second display regions 48 (48 a to 48 e), a single payline L2 is set horizontally across the second display regions 48 (48 a to 48 e) (see FIG. 3). The paylines L1 and L2 indicate the valid range for judging whether a combination of symbols is the winning combination associated with a payout or not. Namely, in the case where a combination of symbols that are stopped on the payline L1 or L2 is the winning combination, the number of coins according to that winning combination and the number of coins entered (BET number) will be paid.
  • In the first embodiment, an exemplary case of setting one payline L1 or L2 on a horizontal line at a middle level of each display region will be described, but the present invention is not limited to this example. For example, three lines that run horizontally across the display regions at upper, middle and lower levels, or two lines among them, maybe set as the paylines. It is also possible to set a payline that runs obliquely (V-shaped, inverted V-shaped, etc.). The paylines L1 and L2 may be set at the same position or at different positions.
  • It is also possible to set as many paylines as the number according to the number of coins entered. In this case, if a combination of symbols that are stopped on the set paylines is the winning combination, the payout of as many coins as according to that winning combination may be made, for example.
  • On a front face of the lower side image display panel 16, a touch panel 69 (not shown in FIG. 2, see FIG. 6) is provided, such that the player can input various types of commands by operating the touch panel 69.

  • FIG. 4 is a diagram showing a series of symbols to be scrolled in the first display regions 28 (28 a to 28 e) of the liquid crystal display 17 a and the code number of each symbol. As shown in FIG. 4, in each of the first display regions 28 (28 a to 28 e), a series of 22 symbols comprising the code numbers “00” to “21” will be scrolled. The arrangement of symbols is different in different ones of the first display regions 28 (28 a to 28 e).
  • The symbols to be displayed in each of the first display regions 28 (28 a to 28 e) include ten types of “JACKPOT 7”, “BLUE 7”, “BELL”, “CHERRY”, “STRAWBERRY”, “PLUM”, “ORANGE”, “APPLE”, “LOBSTER” and “CRAB”. Then, the winning combination associated with a payout is determined by a combination of the above described symbols. As a table for determining the payout amount when this winning combination is realized, a first payout table and a second payout table to be described below are set up.
  • FIG. 5 is a diagram showing an arrangement of tag information which is set in correspondence to each symbol displayed in the first display regions 28 (28 a to 28 e) of FIG. 4. For example, in the case of the symbol “PLUM” of the code number 01 in the first display region 28 a, the corresponding tag information is “A-2”. This tag information is randomly assigned to each symbol in the first display regions 28 (28 a to 28 e). In the first embodiment, each tag information shown in FIG. 5 will be displayed in a vicinity of each symbol displayed in the first display regions 28 (28 a to 28 e), as well as in a vicinity of each symbol displayed in the second display regions 48 (48 a to 48 e) (see FIGS. 15A and 15B). However, it may be made such that the tag information will not be displayed in a vicinity of the symbol.
  • FIG. 6 is a tag arrangement table showing an arrangement of the tag information (tag arrangement). As shown in FIG. 6, in each block (a rectangular frame for displaying one symbol) of the second display regions 48 (48 a to 48 e), the tag information such as A-1, A-2, E-2, E-3 is set up. As will be described below, when the base game is executed and the symbols are rearranged in the first display regions 28 (28 a to 28 e), whether to make a transition to the sub game or not is judged. At this point, when it is determined to make a transition to the sub game, the code number and the tag information for each symbol of each block displayed in the first display regions 28 (28 a to 28 e) are referred, and the rearrangement is made according to the tag arrangement table shown in FIG. 6. The tag information is randomly assigned to each symbol of the first display regions 28 (28 a to 28 e), so that the rearranged positions will be different even for the same symbols.
  • FIG. 7A is a diagram showing the first payout table, which shows combinations of symbols to be aligned on the payline L1. This first payout table will be selected when the usual base game is executed.
  • As shown in FIG. 7A, in the case where a combination of symbols “APPLE” is stopped on the payline L1 in the five first display regions 28 (28 a to 28 e), it becomes the bonus trigger and a transition of the game mode from the base game to the bonus game is made.
  • The bonus game which is executed when a combination of symbols “APPLE” is stopped on the payline L1 in this way is a game mode which is more advantageous than the base game. In the first embodiment, the bonus game is a free game (a game that can be played for a prescribed number of times without betting any coins). Here, however, the content of the bonus game that is more advantageous to the player is not particularly limited as long as it is more advantageous than the base game. For example, it is possible to consider a mode in which more numerous gaming medium than the base game can be obtained, a mode in which the gaming medium can be obtained at a higher probability than the base game, a mode in which the amount of gaming medium to be consumed is less than the base game, etc. More specifically, a free game, a second game, etc. can be considered as the bonus game.
  • In the case where a combination of symbols “LOBSTER” that are prescribed symbols is stopped on the payline L1, the payout of 25 coins will be made. In the case where a combination of symbols “CHERRY” is stopped on the payline L1, the payout of 20 coins will be made. In the case where a combination of symbols “PLUM” is stopped on the payline L1, the payout of 15 coins will be made.
  • On the other hand, FIG. 7B is a diagram showing the second payout table, which shows combinations of symbols to be aligned on the payline L2. This second payout table will be selected when the sub game is executed. As shown in FIG. 7B, in the case where a combination of symbols “APPLE” is stopped on the payline L2, the payout of 20 coins will be made. In the case where a combination of symbols “LOBSTER” is stopped on the payline L2, the payout of 15 coins will be made. In the case where a combination of symbols “CHERRY” is stopped on the payline L2, the payout of 10 coins will be made. In the case where a combination of symbols “PLUM” is stopped on the payline L2, the payout of 5 coins will be made.
  • As will be described below, in the base game, the amount of payout is determined as the first payout table is selected. The, the sub game is executed, and when a combination of specific symbols such as a combination of symbols “CRAB”, for example, is stopped on the payline L2, the second payout table is selected.
  • The symbols displayed (arranged) in the first display regions 28 (28 a to 28 e) are started to be scrolled when the 1-BET button 26 or the Max-BET button 27 is pressed and then the spin button 23 is pressed after that. When the scrolling of the symbols is started, the scrolling of the symbols will be stopped (rearranged) after a prescribed period of time has elapsed. At this point, some of the symbols among the series of symbols in the first display regions 28 (28 a to 28 e) shown in FIG. 4 will be stopped in the first display regions 28 (28 a to 28 e) inside the display window 15.
  • In addition, various types of winning combinations are predetermined for each symbol (see FIG. 7A). Then, in the case where the symbols that constitute the winning combination are stopped on the payline L1, the amount of coins to be paid according to the winning combination will be added to the credit owned by the player. When the bonus game trigger is realized, that is, when a combination of five symbols “APPLE” is stopped on the payline L1 in the first embodiment, a transition of the game mode from the base game to the bonus game will be made.
  • FIG. 8 is a block diagram showing a control circuit of the slot machine 10 shown in FIG. 2. As shown in FIG. 8, the control circuit comprises a controller 70, a main body PCB (Printed Circuit Board) 60, a sub CPU 61, a door PCB 80, and various types of switches and sensors.

  • Namely, the controller 70 containing the main CPU 41 has a function for executing an arrangement control which, after a plurality of symbols displayed in the first display regions 28 (28 a to 28 e) of the liquid crystal display 17 a are scrolled, selects and determines symbols to be arranged into a symbol matrix from plural types of symbols randomly, and stops the scrolling state at the determined symbols, in order to rearrange them into a new symbol matrix (an arrangement of three rows by five columns).
  • The controller 70 has a function of a payout table selection controller which selects the first payout table and determines the amount of payout according to this first payout table when a prescribed combination of symbols is rearranged on the payline L1 that is set with respect to the symbol matrix, that is when the winning combination is realized, by the execution of the base game. This payout table selection controller also has a function for selecting the second payout table and determining the amount of payout according to this second payout table when a prescribed combination of symbols is rearranged on the payline L2 that is set with respect to the symbol matrix, that is when the winning combination is realized, by the execution of the sub game.

  • The ROM 42 stores programs such as BIOS (Basic Input/Output System) to be executed by the main CPU 41, as well as data to be used permanently. When the BIOS is executed by the main CPU 41, the processing for initializing each peripheral device is carried out and the processing for reading the game program and the game system program stored in the memory card 53 through the gaming board 50 is started. The ROM 42 also stores the tag arrangement table shown in FIG. 6, the first payout table shown in FIG. 7A, and the second payout table shown in FIG. 7B.
  • The RAM 43 stores data and programs to be used when the main CPU 41 carries out the processing.

  • Next, the concrete processing to be carried out at the slot machine 10 will be described. FIG. 9 is a flow chart showing a procedure of the authentication and reading processing for the game program and the game system program (processing at the step S100 shown in FIG. 1), by the mother board 40 and the gaming board 50 shown in FIG. 8. Here it is assumed that the memory card 53 is attached to the card slot 53S and the GAL 54 is attached to the IC socket 54S on the gaming board 50.
  • First, when the power switch is turned on at the power source unit 45, the mother board 40 and the gaming board 50 are activated (steps S1-1, S2-1). When the mother board 40 and the gaming board 50 are activated, the respective independent processings will be carried out in parallel. Namely, at the gaming board 50, the CPU 51 carries out the reading of the spare authentication program stored in the boot ROM 52, and the spare authentication for checking and verifying that the authentication program is not falsified in advance, according to the read out spare authentication program, before it is taken into the mother board 40 (step S2-2).
  • On the other hand, at the mother board 40, the main CPU 41 executes the BIOS stored in the ROM 42 and expands the compressed data incorporated in the BIOS over the RAM 43 (step S1-2). Then, the main CPU 41 executes the BIOS expanded on the RAM 43 to carry out the diagnosis and initialization of various types of peripheral devices (step S1-3).
  • Then, as the ROM 55 of the gaming board 50 is connected to the main CPU 41 through the PCI bus, the main CPU 41 carries out the reading of the authentication program stored in the ROM 55. In addition, the main CPU 41 carries out the processing for storing the read out authentication program into the RAM 43 (step S1-4).
  • Next, the main CPU 41 makes an access to the memory card 53 that is attached to the card slot 53S through the IDE bus. Then, the main CPU 41 carries out the reading of the game program and the game system program stored in the memory card 53.
  • Next, the main CPU 41 carries out the authentication for checking and verifying that the read out game program and game system program are not falsified, according to the authentication program stored in the RAM 43 (step S1-5).
  • When this authentication processing is finished normally, the main CPU 41 stores the authenticated game program and game system program into the RAM 43 (step S1-6). Next, the main CPU 41 makes an access to the GAL 54 that is attached to the IC socket 54S through the PCI bus, reads out the payout rate setting data from the GAL 54, and stores it into the RAM 43 (step S1-7). Next, the main CPU 41 carries out the reading of the country identification information stored in the ROM 55 of the gaming board 50, and stores the read out country identification information into the RAM 43 (step S1-8).
  • After carrying out the above described processing, the main CPU 41 sequentially reads out and executes the game program and the game system program, to proceed with the base game as described below.
  • After the authentication and reading processing shown in FIG. 9 is carried out, the main CPU 41 carries out the base game execution processing. FIG. 10 is a flow chart showing the concrete processing procedure of the base game execution processing shown at the step S200 of FIG. 1.
  • In the base game execution processing, first. the main CPU 41 judges whether the coin BET has been made or not (step S11). In this processing, the main CPU 41 judges whether the input signal outputted from the 1-BET switch 26S when the 1-BET button 26 is pressed or the input signal outputted from the Max-BET switch 27S when the Max-BET button 27 is pressed has been received or not. When it is judged that the coin BET has not been made, the processing returns to the step S11.
  • On the other hand, at the step S11, when it is judged that the coin BET has been made, the main CPU 41 carries out the processing for subtracting the credit amount stored in the RAM 43 according to the number of coins to be bet (step S12). When the number of coins to be bet is greater than the credit amount stored in the RAM 43, the processing is returned to the step S11, without carrying out the processing for subtracting the credit amount stored in the RAM 43. When the number of coins to be bet exceeds the upper limit value (50 in the first embodiment) that can be bet per one game, the processing proceeds to the step S13, without carrying out the processing for subtracting the credit amount stored in the RAM 43. In this state, it becomes a state where it is possible to scroll symbols in the first display regions 28 (28 a to 28 e).
  • Next, the main CPU 41 judges whether the spin button 23 is turned ON or not (step S13). In this processing, the main CPU 41 judges whether the input signal outputted from the spin switch 23S when the spin button 23 is turned ON is received or not.
  • When it is judged that the spin button 23 is not turned ON, the processing is returned to the step S11. In the case where the spin button 23 is not turned ON (the case where a command indicating the finishing of the game is inputted without turning the spin button 23 ON, for example), the main CPU 41 cancels the subtraction result at the step S12.
  • In the first embodiment, the exemplary case of carrying out the processing for subtracting the credit amount (step S12) after the coin BET is made (step S11), before making the judgment as to whether the spin button 23 is turned ON or not (step S13) will be described. However, the present invention is not limited to this exemplary case. For example, it is also possible to make the judgment as to whether the spin button 23 is turned ON or not (step S13) after the coin BET is made (step S11), and carry out the processing for subtracting the credit amount (step S12) when it is judged that the spin button 23 is turned ON (step S13 YES).
  • Then, at the step S13 of FIG. 10, when it is judged that the spin button 23 is turned ON, the main CPU 41 carries out the symbols to be stopped determination processing (step S14). In this symbols to be stopped determination processing, the main CPU 41 determines symbols to be displayed through the display window 15 at a time of stopping symbols in the first display regions 28 (28 a to 28 e) by executing the symbols to be stopped determination program stored in the RAM 43. In this way, the combination of symbols to be stopped on the payline L1 is determined.
  • Next, the main CPU 41 carries out the symbols scroll processing (step S15). This processing is a processing for stopping symbols in the first display regions 28 (28 a to 28 e) after the scrolling of symbols in the first display regions 28 (28 a to 28 e) is started, such that symbols determined at the step S14 will be stopped on the payline L1.
  • Next, the main CPU 41 judges whether the bonus trigger is realized or not, that is, whether the combination of symbols stopped on the payline L1 is the combination of symbols “APPLE” or not (step S16). When it is judged that the bonus trigger is realized, the main CPU 41 executes the bonus game processing to be described below (step S17).
  • When it is judged that the bonus trigger is not realized, the main CPU 41 judges whether the winning combination is realized or not, that is, whether the combination of symbols “LOBSTER” is stopped on the payline L1 or not, for example (step S18). Here, when it is judged that the winning combination is realized, the main CPU 41 carries out the payout processing corresponding to this winning combination, according to the first payout table (step S19). On the other hand, when it is judged that the winning combination is not realized, that is, in the case where any of the bonus trigger and the winning combinations is realized, the main CPU 41 executes the sub game processing to be described below (step S20).
  • In the case of depositing the paid coins, the main CPU 41 adds the prescribed amount of credit to the credit amount stored in the RAM 43. In the case of paying the coins, the main CPU 41 makes the payout of a prescribed number of coins by transmitting the control signal to the hopper 66. At this point, the coin detection unit 67 counts the number of coins paid from the hopper 66, and transmits a payout completion signal to the main CPU 41 when the count value reached the specified number. As a result, the main CPU 41 stops the driving of the hopper 66 and finishes the coin payout processing.
  • Next, the symbols to be stopped determination processing shown at the step S14 of FIG. 10 will be described with reference to a flow chart shown in FIG. 11.
  • FIG. 11 is a flow chart showing a procedure of the symbols to be stopped determination processing shown at the step S14 of FIG. 10. This processing is a processing to be carried out as the main CPU 41 executes the symbols to be stopped determination program stored in the RAM 43.
  • First, the main CPU 41 selects a random number value corresponding to each column of the first display regions 28 (28 a to 28 e) from a numerical value range of 0 to 255, by executing the random number generation program contained in the symbols to be stopped determination program (step S51).
  • Next, the main CPU 41 refers to the symbol weighing data according to the payout rate setting data outputted from the GAL 54 and stored in the RAM 43, and determines the code numbers (see FIG. 4) for the first display regions 28 (28 a to 28 e) according to the selected five random number values (step S52).
  • The code numbers of the first display regions 28 (28 a to 28 e) correspond to the code numbers of symbols to be stopped and displayed on the payline L1. Symbols are scrolled in the arrangement as shown in FIG. 4, so that when the code numbers of symbols to be stopped and displayed on the payline L1 are determined, the code numbers of symbols to be stopped and displayed on upper and lower level horizontal lines of the payline L1 are also determined. The main CPU 41 determines the winning combination by determining the code numbers of the first display regions 28 (28 a to 28 e). For example, when the code numbers of the first display regions 28 (28 a to 28 e) are determined as “00”, “00”, “00”, “00” and “00”, the main CPU 41 has determined the combination of symbols “JACKPOT 7” as the winning combination.
  • FIG. 12 is a flow chart showing a procedure of the symbols scroll processing shown at the step S15 of FIG. 10. This processing is a processing carried out between the main CPU 41 and the sub CPU 61.
  • First, the main CPU 41 transmits a start signal indicating that the symbols scrolling will be started in the first display regions 28 of the liquid crystal display 17 a, to the sub CPU 61 (step S61). Upon receiving the start signal from the main CPU 41, the sub CPU 61 reads out the image data of symbols stored in the image data ROM 47, and carries out the scrolling of symbols in the five columns of the first display regions 28 (28 a to 28 e) of the liquid crystal display 17 a (step S71). As a result, the scrolling of symbols is started in the five columns of the first display regions 28 (28 a to 28 e).
  • After transmitting the start signal to the sub CPU 61 at the step S61 shown in FIG. 12, the main CPU 41 executes the effects at a time of the symbol scrolling (step S62). This processing is a processing for displaying the images on the lower side image display panel 16 and outputting sounds from the speaker 29, etc., during a period (three seconds, for example) determined according to the result of the symbols to be stopped determination processing (step S14 of FIG. 10), etc.
  • Next, the main CPU 41 judges whether it is a timing for commanding the stopping of the scrolling or not (step S63 of FIG. 12).
  • When it is judged that it is not a timing for commanding the stopping of the scrolling at the step S63, the processing is returned to the step S63 and the effects at a time of the scrolling are continued. When it is judged that it is a timing for commanding the stopping of the scrolling at the step S63, the main CPU 41 transmits the code numbers of symbols stored in the RAM 43 to the sub CPU 61 (step S64). Upon receiving the code numbers of symbols from the main CPU 41, the sub CPU 61 determines the scrolling stopping position such that it corresponds to these code numbers (step S72).
  • After that, the scrolling stopping processing is carried out, and symbols are stopped and displayed in the first display regions 28 (28 a to 28 e) that are inside the display window 15 (step S73). Also, the display processing of the effect images by the main CPU 41 is finished (step S65).
  • FIG. 13 is a flow chart showing a procedure of the bonus game processing shown at the step S19 of FIG. 10. In the bonus game processing, first, the main CPU 41 determines the number of times for executing the bonus game T from a range of 10 to 25 games, according to the random number value obtained by executing the random number generation program contained in the symbols to be stopped determination program stored in the RAM 43 (step S81). The main CPU 41 stores the determined data on the number of games T of the bonus game into the RAM 43.
  • Next, the main CPU 41 carries out the symbols to be stopped determination processing (step S82) and the symbols scroll processing (step S83). The processing of the step S82 is similar to the processing described above with reference to FIG. 11. The processing of the step S83 is similar to the processing described above with reference to FIG. 12. These processings have already been described above, so that their description will be omitted here.
  • Next, in FIG. 13, the main CPU 41 judges whether the bonus game trigger is realized or not, that is, whether the combination of symbols “APPLE” is stopped on the payline L formed in the first display regions. 28 (28 a to 28 e) inside the display windows 15 or not (step S84). When it is judged that the bonus game trigger is realized (step S84 YES), the number t of repetitions of the bonus game is newly determined (step S85), and the determined number t of repetitions is added to the current number of games T of the bonus game (step S86). In this way, when the bonus game is won again during the bonus game, the remaining number of the bonus games will be increased.
  • When the bonus game trigger is not realized, the main CPU 41 judges whether the winning combination is realized or not (step S87). When it is judged that the winning combination is realized, the main CPU 41 makes the payout of coins according to the number of coins entered and the winning combination (step S88). At this point, the payout according to the first payout table shown in FIG. 7A is made.
  • When the processing of the steps S86 or S88 is executed, or when it is judged that any of the winning combinations is not realized at the step S87 (it is judged as a lost game), the main CPU 41 reads out the number of games T of the bonus game stored in the RAM 43, subtracts one from the read out value of the number of games T, and stores the number of games T after the subtraction into the RAM 43 again (step S89).
  • Next, the main CPU 41 judges whether the number of games T of the bonus game has reached the number of times determined at the step S81 or not (step S90). More specifically, it is judged by judging whether the number of games T stored in the RAM 43 has become zero or not, and when the number of games T is not zero, that is, when it is judged that the number of executed bonus games has not reached the number of times determined at the step S81, the processing is returned to the step S82 and the above described processing is repeated.
  • On the other hand, when the number of games T is zero, that is, when it is judged that the number of executed bonus games has reached the number of games T determined at the step S81, the processing is finished. The bonus game is carried out in this way.
  • Next, the sub game processing will be described. FIG. 14 is a flow chart showing a procedure of the sub game processing shown at the step S20 of FIG. 10.
  • First, the main CPU 41 acquires the code number of each symbol rearranged in the first display regions 28 (28 a to 28 e), and the tag information (see FIG. 5) corresponding to each code number (step S101).
  • Next, the main CPU 41 rearranges the code numbers of the symbols according to the tag information and the tag arrangement table (see FIG. 6) (step S102). For example, when symbols rearranged in the first display region 28 a (the left most column) are “ORANGE”, “PLUM” and “LOBSTER” sequentially from top to bottom, the code numbers of these symbols are “02”, “03” and “04” sequentially from top to bottom, and the corresponding tag informations are “A-3”, “A-1” and “A-2” sequentially from top to bottom. Then, when these code numbers are rearranged according to the tag information and the tag arrangement table (FIG. 6), the code numbers will be “03”, “04” and “02” sequentially from top to bottom.
  • Next, the main CPU 41 rearranges symbols in correspondence to the arrangement of these code numbers (step S103). For example, symbols rearranged in block of the second display region 48 a (the left most column) will be “PLUM”, “LOBSTER” and “ORANGE” sequentially from top to bottom. The main CPU 41 rearranges the code numbers of symbols in the other first display regions 28 b to 28 e by the similar processing, and determines symbols to be displayed in blocks of the second display regions 48 (48 a to 48 e).
  • Next, the main CPU 41 judges whether the winning combination associated with a payout is stopped on the payline L2 that is set as a middle level horizontal line in the second display regions 48 or not, that is, whether the winning combination is realized or not (step S104). Here, when the winning combination is realized, the payout processing corresponding to the winning combination is carried out according to the second payout table (step S105).
  • FIG. 15A is a diagram showing an exemplary display at the first display regions 28 when the base game is executed, and FIG. 15B is a diagram showing an exemplary display at the second display regions 48 when the sub game is executed.
  • In the exemplary display shown in FIG. 15A, the winning combination associated with a payout is not stopped on the payline L1 of the first display regions 28 (28 a to 28 e), so that the sub game will be executed subsequently. In this sub game, the rearrangement of symbols is carried out according to the procedure described above, and the rearranged symbols are displayed in the second display regions 48 (48 a to 48 e). In the exemplary display shown in FIG. 15B, the combination of symbols “LOBSTER” which is the winning combination is stopped on the payline L2 of the second display regions 48 (48 a to 48 e), so that the payout of 15 coins will be made according to the second payout table.
  • As described above, in the slot machine and the playing method according to the first embodiment, a base game for randomly rearranging a plurality of symbols, and a sub game for rearranging a plurality of symbols rearranged by this base game according to prescribed rules are executed, and a prescribed payout is made when a winning combination associated with a payout is included in the combinations of rearranged symbols, so that even if the winning combination is not realized in the base game that is initially executed, the player can obtain a prize if the winning combination is realized in the subsequent sub game. Consequently, it is possible to make the player to continually maintain the interest in the game.
  • In the first embodiment, the symbols are rearranged according to the tag information that is set in correspondence to each symbol and the predetermined tag arrangement (tag arrangement table), so that a complicated program for rearranging symbols becomes unnecessary, and it is possible to simply the processing of the main CPU 41.
  • In addition, in the first embodiment, the rearranged symbols of the base game are displayed in the first display regions 28 and the rearranged symbols of the sub game are displayed in the second display regions 48, so that the player can enjoy how symbols are rearranged by the sub game in comparison with the symbol arrangement of the base game. The tag information is displayed in a vicinity of the symbol, so that the player can confirm that the rearrangement of symbols by the sub game is carried out properly according to the tag information, and it is possible to improve the reliability of the game.
  • Second Embodiment
  • Next, the second embodiment of the present invention will be described. In the following, the configuration characteristic to the second embodiment and its effects will be described. The description of the configuration and functions common to the first embodiment will be omitted.
  • The main CPU 41 in the second embodiment has a function of a symbol rearrangement controller for making symbols appear to be rearranged by randomly assigning a background color to each symbol rearranged by the base game and carrying out a color by color display based on each background color. Namely, in the second embodiment, randomly assigning a background color to each symbol is used as a prescribed rule for rearranging a plurality of symbols. In other words, randomly assigning a background color to each symbol without changing a position of each symbol is regarded as the rearrangement of symbols. In the second embodiment, by carrying out such an assignment of a background color, even if the combination of identical symbols is seemingly not on the payline, it is virtually regarded that the combination of identical symbols is on the payline and the payout is made as long as at least two or more of identical symbols with the identical background color are arranged. Which background color is to be regarded as the virtual payline may be set in advance, or may be selected randomly every time the sub game is executed.
  • The base game execution processing and the other related processing in the second embodiment are the same as the first embodiment so that their description will be omitted. In the following, the sub game processing in the second embodiment will be described. FIG. 16 is a flow chart showing a procedure of the sub game processing shown at the step S20 of FIG. 10.
  • First, the main CPU 41 randomly assigns a background color to each symbol rearranged in the first display regions 28 (28 a to 28 e) (step S201). For example, a background color can be randomly assigned to each symbol by executing a random number generation program and extracting one background color randomly from a plurality of background colors set in advance. Next, the main CPU 41 displays the assigned background color on a background of each symbol rearranged in the second display regions 48 (48 a to 48 e)(step S202).
  • At this point, in order to making it easier to recognize the realization of the winning combination in the sub game, it is preferable to make it such that two or more of the identical background color will not be assigned in each column. When a transition to the sub game is made, symbols in the same arrangement as in the first display regions 28 (28 a to 28 e) and a plain (white, for example) background color are displayed in the second display regions 48 (48 a to 48 e). Then, when the sub game is executed, the respective background colors are assigned to the second display regions 48 (48 a to 48 e).
  • Next, the main CPU 41 judges whether at least two or more of identical symbols with a background color “red”, for example, are arranged or not, that is, whether the winning combination is realized on the virtual payline or not (step S203). Here, when the winning combination is realized, the payout processing corresponding to the winning combination is carried out according to the second payout table (step S204).
  • FIG. 17A is a diagram showing an exemplary display at the first display regions 28 when the base game is executed, and FIG. 17B is a diagram showing an exemplary display at the second display regions 48 when the sub game is executed.
  • In the exemplary display shown in FIG. 17A, the winning combination associated with a payout is not stopped on the payline L1 of the first display regions 28 (28 a to 28 e), that is, the winning combination is not realized, so that the payout and the like will not be made. In this case, the sub game will be executed subsequently. In this sub game, the arrangement of symbols is unchanged but the randomly assigned background colors are displayed. As a result, the assignment of background colors as shown in FIG. 17B, for example, is made. In FIG. 17B, even if the payline is set as a horizontal line at a middle level, the winning combination will not be realized. However, in the second display regions 48 (48 a to 48 e), five symbols “LOBSTER”with the red background color are arranged, so that they are virtually regarded as located on the payline, and it is judged that the winning combination is realized. Consequently, the payout processing is carried out according to the second payout table.
  • In the second embodiment, it may be made such that it is virtually regarded as located on the payline and the payout is made as long as at least two or more of identical symbols with the identical background color are arranged. In this case, it may be made such that the payout amount is different according to the number of identical symbols with the identical background color that are arranged. It may be made such that the payout amount is different for different background colors, or such that the payout amount is changed according to a combination of the background color and the symbol.
  • As described above, in the slot machine and the playing method according to the second embodiment, a background color is randomly assigned to each symbol rearranged by the base game, and each symbol is made to appear to be rearranged by carrying out a color by color display based on each background color, so that it can be expected that the player has an interest regarding which background color is going to be assigned to each symbol. The player can enjoy the change of images in the display regions. Consequently, it is possible to increase the player's interest in the game.
  • In the second embodiment, the respective background colors of the symbols rearranged in the second display regions 48 (48 a to 48 e) may be displayed simultaneously, or may be displayed sequentially in the horizontal direction or the vertical direction. It may be made such that the background colors are displayed with one column or one row interval, or the background colors are displayed sequentially one color after another. It may be made such that, without using the second display regions 48 (48 a to 48 e), only the background colors are displayed in the first display regions 28 (28 a to 28 e) in a state where symbols are displayed (with a plain background), when the sub game is executed.
  • Third Embodiment
  • Next, the third embodiment of the present invention will be described. In the following, the configuration characteristic to the third embodiment and its effects will be described. The description of the configuration and functions common to the first embodiment will be omitted.
  • The main CPU 41 in the third embodiment has a function of a symbol rearrangement controller for rearranging a plurality of symbols rearranged by the base game while displaying a manner by which each symbol sequentially moves in the first display regions 28, at a time of rearranging symbols according to prescribed rules in the sub game.
  • In the third embodiment, a block sliding processing to be described below is executed as a prescribed rule for rearranging a plurality of symbols in the sub game processing. In the slot machine of the third embodiment, the rearrangement of symbols by the sub game is displayed in the same first display regions 28 used by the base game.
  • The base game execution processing and the other related processing in the third embodiment are the same as the first embodiment so that their description will be omitted. In the following, the sub game processing in the third embodiment will be described. FIG. 18 is a flow chart showing a procedure of the sub game processing shown at the step S20 of FIG. 10.
  • First, the main CPU 41 acquires the code number of each symbol rearranged in the first display regions 28 (28 a to 28 e), and the tag information that is set in correspondence to that symbol (step S301). Next, the main CPU 41 determines the code number and the tag information of the symbol to be rearranged in each block of the symbol matrix by executing a block sliding processing to be described below (step S302). As shown in FIG. 4 and FIG. 5, the symbol can be identified when the code number and the tag information are ascertained. For example, if the code number is “08” and the tag information is “B-2”, the symbol is “BELL”. Next, the main CPU 41 rearranges the symbol corresponding to the determined code number and tag information in each block of the symbol matrix (step S303).
  • Next, the main CPU 41 judges whether the winning combination associated with a payout is stopped on the payline L1 that is set as a middle level horizontal line in the first display regions 28 (28 a to 28 e) or not, that is, whether the winning combination is realized or not (step S304). Here, when the winning combination is realized, the payout processing corresponding to the winning combination is carried out according to the second payout table (step S305).
  • FIG. 19 is a flow chart showing a procedure of the block sliding processing shown at the step S302 of FIG. 18. In this block sliding processing, the main CPU 41 secures a plurality of memory areas corresponding to the symbol matrix (three rows by five columns) on the RAM 43, and stores the code number and the tag information of a moved block into the memory area corresponding to a moving target block.
  • First, the main CPU 41 sets a count number n to 0 (step S401), and sets a central block in the symbol matrix to be a vacant block (step S402). Here, a vacant block is a block in which the symbol is deleted and only the background is displayed. At this point, the code number and the tag information of the deleted symbol are stored into the RAM 43. Next, the main CPU 41 judges whether there are two or more movable blocks at upper, lower, right and left neighbors of the vacant block or not (step S403). Here, the block that had been moved immediately previously is removed from targets. When there are two or more movable blocks at the step S403, one movable block is determined by executing a random number generation program, for example (step S404). Then, the determined block is moved to the vacant block, and the symbol is deleted from the block before moving such that it becomes a vacant block (step S405). When two or more movable blocks are not there at the step S403, that is when there is only one movable block, the main CPU 41 moves the symbol of the movable block to the vacant block, and the symbol is deleted from the block before moving such that it becomes a vacant block (step S406).
  • Next, the main CPU 41 sets the counter number n to n+1 (step S407), and further judges whether n=N or not (step S408). Here, N indicates a number of times for moving blocks that is set in advance. When it is not n=N at the step S408, the main CPU 41 returns the processing to the step S403, and the moving to a vacant block is repeated until it becomes n=N. Then, when it becomes n=N at the step S408, the code number and the tag information of a first deleted symbol are stored into the memory area corresponding to the vacant block (step S409). As a result, the code number and the tag information of the symbols rearranged by the block moving are stored in a plurality of memory areas that correspond to the symbol matrix.
  • In this block sliding processing, the main CPU 41 moves a symbol of a block to be moved, into a vacant block in the first display regions 28 (28 a to 28 e) whenever one block is moved, and displays a manner by which a symbol is deleted from a block before moving such that it becomes a vacant block on the display. More specifically, the main CPU 41 transmits the code number and the tag information of every one of three rows and five columns stored in the memory areas of the RAM 43 to the sub CPU 61. Upon receiving the code number and the tag information from the main CPU 41, the sub CPU 61 reads out all the image data corresponding to these code number and tag information, and displays them in the first display regions 28 (28 a to 28 e).
  • The method of the block sliding processing is not limited to that of the third embodiment. Namely, any other method can be used as long as it can randomly rearrange a plurality of symbols.
  • FIG. 20A to FIG. 20E show a manner by which blocks are moved by the block sliding processing. Here, for the same of simplifying the explanation, an exemplary case of the symbol matrix of three rows by three columns will be described. The left side of the figures show the symbol matrix, and the right side of the figures show a plurality of memory areas corresponding to the symbol matrix.
  • First, the main CPU 41 sets a center block of the symbol matrix to be a vacant block. In FIG. 20A, “LOBSTER” becomes a vacant block, and this symbol is deleted. At the same time, the main CPU 41 stores the code number “05” and the tag information “B-2” of the deleted symbol “LOBSTER” into another memory area. Next, the main CPU 41 determines one movable block. Here, there are four movable blocks at upper, lower, right and left neighbors of the vacant block, so that one movable block is determined by executing the random number generation program. Here, it is assumed that it is determined as “PLUM” at the lower neighbor of the vacant block. Next, the main CPU 41 moves the symbol “PLUM” into the vacant block, while deleting the symbol “PLUM” from a block before moving, as shown in FIG. 20B. At the same time, the main CPU 41 stores the code number “06” and the tag information “B-3” of the moved symbol “PLUM” into a memory area corresponding to a moving target block.
  • Then, the main CPU 41 determines one movable block. Here, there are two movable blocks at right and left neighbors of the vacant block, so that one movable block is determined by executing the random number generation program. Here, it is assumed that it is determined as “PLUM” at the right neighbor of the vacant block. Next, the main CPU 41 moves the symbol “PLUM” into the vacant block, while deleting the symbol “PLUM” from a block before moving, as shown in FIG. 20C. At the same time, the main CPU 41 stores the code number “05” and the tag information “B-3” of the moved symbol “PLUM” into a memory area corresponding to a moving target block.
  • Then, the main CPU 41 determines one movable block. Here, there is only one movable block, so that it is determined as “ORANGE” at the upper neighbor of the vacant block. Next, the main CPU 41 moves the symbol “ORANGE” into the vacant block, while deleting the symbol “ORANGE” from a block before moving, as shown in FIG. 20D. At the same time, the main CPU 41 stores the code number “04” and the tag information “C-2” of the moved symbol “ORANGE” into a memory area corresponding to a moving target block.
  • Assuming that the number N of times for moving blocks is reached at this stage, the main CPU 41 stores the code number “05” and the tag information “B-2” of the symbol “LOBSTER” that had been stored in another memory area, into a memory area corresponding to the vacant block. As a result, the code number and the tag information of each symbol are stored in a plurality of memory areas corresponding to the symbol matrix, as shown in FIG. 20E. Then, images in which the symbols are rearranged will be displayed in the first display regions 28 (28 a to 28 e), according to the code number and the tag information of each symbol. In the third embodiment, a manner by which the symbols are sequentially moved and rearranged will be displayed in the first display regions 28 (28 a to 28 e) in conjunction with the start of the sub game.
  • As described above, in the slot machine and the playing method according to the third embodiment, at a time of rearranging a plurality of symbols rearranged by the base game, according to prescribed rules in the sub game, they are rearranged while displaying a manner by which each symbol is sequentially moved in the first display regions 28, so that the player can enjoy a manner by which symbols are moved as if they are slide puzzles. It can be expected that the player has an interest regarding to which position the symbol is going to be moved. Consequently, it is possible to increase the player's interest in the game.
  • The effects that can be obtained by the configuration and functions equivalent to those of the first embodiment can also be commonly obtained in the third embodiment as well.
  • In the first to third embodiments described above, the sub game is executed when the winning combination is not realized in the base game, so that the player is given a chance to obtain a prize in a subsequent sub game even when a prize cannot be obtained by the initial base game. Consequently, the player can enjoy at least two games even in the case where a prize cannot be obtained in both games.
  • As another embodiment, it may be made such that the sub game is executed only in the case where the winning combination is realized in the base game. In this case, the payout obtained by summing the payout amount due to the winning combination realized in the sub game and the payout amount due to the winning combination realized in the base game may be made, or the payout in the payout amount more advantageous to the player may be made. According to this embodiment, the player can obtain the payout due to the sub game or the more advantageous payout in addition to the payout due to the base game, so that it is possible to increase the player's interest in the game.
  • As still another embodiment, it may be made such that whether the sub game is to be executed or not is determined randomly after the symbols are rearranged by the base game. In this case, whether the sub game is to be executed or not can be determined randomly by executing the random number generation program similarly as in the symbols to be stopped determination processing. In this case, the player cannot ascertain whether a transition to the sub game is going to be made or not until the base game is finished, so that it becomes possible to arouse an expectation for a next game in the player, so that it is possible to increase the player's interest in the game. As an embodiment other than those described above, it may be made to execute the sub game regardless of whether the winning combination is realized in the base game or not.
  • In the above, the embodiments of the slot machine and the playing method according to the present invention have been described, but they are only showing concrete examples. Namely, the above described embodiments are not intended to limit the present invention, and the concrete configuration of each means or the like can be appropriately changed by design. Also, the concrete configuration of each means or the like can be replaced by other means having an equivalent functions, or a combination of a plurality of means each having a part of functions, and can also be realized by a part of functions of the other means having expanded functions. Also, the effects described in the embodiments of the present invention are only listing the most preferable effects arising from the present invention, and the effects of the present invention are not limited to those described in the embodiments of the present invention.
