As shown in FIG. 4, the controller 100 of the slot machine 13 is a micro computer, and includes an interface circuit group 102, an input/output bus 104, a CPU 106, ROM 108, RAM 110, a communication interface circuit 111, a random number generator 112, a speaker driving circuit 122, a hopper driving circuit 124, a display unit driving circuit 128, and a display/input controller 140.
The interface circuit group 102 is electrically connected with the input/output bus 104, which carries out the input and output of data signals or address signals for the CPU 106.
The start switch 25 is electrically connected with the interface circuit group 102. In the interface circuit group 102, a start signal generated by the start switch 25 is converted into a predetermined form of signal to be supplied to the input/output bus 104.
Furthermore, the bet switch 23, the spin repeat bet switch 24, and the cash out switch 26 are connected to the interface circuit group 102. Each of the switching signals output from these switches 23, 24, and 26 is also supplied to the interface circuit group 102, and is converted into a predetermined signal by the interface circuit group 102. The switching signals thus converted are supplied to the input/output bus 104.
A coin sensor 43 is also electrically connected with the interface circuit group 102. The coin sensor 43 detects coins inserted into the coin insertion slot 22, and is disposed at an appropriate position relative to the coin insertion slot 22. The sensing signal output from the coin sensor 43 is also supplied to the interface circuit group 102, and is converted into a predetermined signal by the interface circuit group 102. The sensing signal thus converted is supplied to the input/output bus 104.
The ROM 108 and the RAM 110 are connected to the input/output bus 104.
When the start switch 25 accepts an instruction for starting a basic game, the CPU 106 reads a basic game program and executes the basic game. The basic game program has been programmed so as to instruct the CPU 106 to perform the following operations of displaying an image of the five video reels commencing to scroll the symbols on the five video reels on the liquid crystal display 30 via the display/input controller 140; then displaying an image of the five video reels stopping such that the combination of the symbols on these five video reels is rearranged, upon which a new combination of the symbols is made along the active pay lines. In a case where a particular combination of the symbols for providing an award has been made along any one of the active pay lines when stationary, the CPU 106 pays out a predetermined amount of coins corresponding to the particular combination for providing the award.
The ROM 108 stores: a control program for central control of the slot machine 13; a program for executing a routine shown in FIG. 8, FIG. 11 and FIG. 17 (which is referred to as the “routine execution program” hereafter); initial data for executing the control program; and various data tables used for determination processing. It should be noted that the routine execution program includes the basic game program and the like. The RAM 110 temporarily stores flags, variables, etc. used for the control program.
Furthermore, a communication interface circuit 111 is connected to the input/output bus 104. The communication interface circuit 111 is a circuit for communicating with a server, etc. via various kinds of communication networks including a public telephone line network, LAN, etc.

The random number generator 112 generates random numbers in a predetermined range of “0” to “65535” (two to the sixteenth power minus one), for example. Alternatively, an arrangement may be made in which the CPU 106 generates a random number by computation.
The display unit driving circuit 128 for driving each of the display units 48 through 50 is connected to the input/output bus 104. The CPU 106 controls the operation of each of the display units 48 through 50 via the display unit driving circuit 128 according to an occurrence of a predetermined event.
The speaker drive circuit 122 for the speakers 41 is also electrically connected with the input/output bus 104. The CPU 106 reads the sound data stored in the ROM 108, and transmits the sound data thus read to the speaker driving circuit 122 via the input/output bus 104. In this way, the speakers 41 generate predetermined sound effects.
The hopper drive circuit 124 for driving the hopper 44 is also electrically connected with the input/output bus 104. Upon reception of a cash out signal input from the cash out switch 26, the CPU 106 transmits a driving signal to the hopper driving circuit 124 via the input/output bus 104. Accordingly, the hopper 44 pays out coins such that the amount thereof is equivalent to the current number of coins remaining as credits, which is stored in a predetermined memory area of the RAM 110.
The display/input controller 140 is connected to the input/output controller 140. The CPU 106 creates an image display command corresponding to the state and results of the game, and outputs the image display command thus created to the display/input controller 140 via the input/output bus 104. Upon reception of the image display command input from the CPU 106, the display/input controller 140 creates a driving signal for driving the liquid crystal display 30 according to the image display command thus input, and outputs the driving signal thus created to the liquid crystal display 30. As a result, a predetermined image is displayed on the transparent liquid crystal panel 34 of the liquid crystal display 30. The display/input controller 140 transmits the signal input through the touch panel 32 provided on the liquid crystal display 30 to the CPU 106 via the input/output bus 104 in the form of an input signal.

FIG. 8 is a flow chart illustrating a flow of the processing operation in the game machine 13 executed by the controller 100 of the game machine 13. The processing operation is called from a main program for the slot machine 13 at a predetermined timing, and is then executed.
A description is provided below regarding a case in which the slot machine 13 has been activated beforehand. Furthermore, let us say that the variables used by the CPU 106 included in the controller 100 have been initialized to predetermined values, thereby operating the slot machine 13 in a normal state.
First, the CPU 106 included in the controller 100 determines whether or not any coins inserted by the player are remaining (Step S1). More specifically, the CPU 106 reads a credit amount C stored in the RAM 110, and executes processing according to the credit amount C. When the credit amount C equals “0” (NO in Step S1), the CPU 106 terminates the routine without executing any processing, since it cannot start a game. When the credit amount C is not less than “1” (YES in Step S1), the CPU 106 determines that coins remain as credits, and the CPU 106 moves the processing to Step S2.
In Step S2, the CPU 106 determines whether or not a pushing operation has been executed on the spin bet repeat switch 24. When the switch 24 has been pushed and the CPU 106 receives an operation signal from the switch 24 (YES in Step S2), the CPU 106 moves the processing to Step S14. On the other hand, when the CPU 106 does not receive the operation signal from the switch 24 after a predetermined period of time elapses (NO in Step S2), the CPU 106 determines that the switch 24 has not been pushed and moves the processing to Step S3.
In the following Step S3, the CPU 106 sets the game conditions. Specifically, the CPU 106 determines the amount of coins bet on the active pay lines in this game based on the operation of the bet switch 23. Then, the CPU 106 determines the bet amount to be bet on the active pay lines based upon the number of signals that indicate operation of the bet switch 23 have been received, and stores the bet amount thus determined in a predetermined memory area of the RAM 110. The CPU 106 reads the credit amount C stored in a predetermined memory area of the RAM 110, and subtracts the total bet amount, which is the sum of the bet amounts, from the credit amount C thus read. Then, the CPU 106 stores the subtracted value in a predetermined memory area of the RAM 110. Subsequently, the CPU 106 moves the processing to Step S4.
In the following Step S4, the CPU 106 determines whether the start switch 25 has been activated, and then waits for the start switch 35 to be operated. Upon the start switch 25 being operated, and accordingly, upon the operation signal being input from the start switch 25 (in a case of “YES” in the determination processing in Step S4), the CPU 106 determines that the start switch 25 has been operated, and the flow proceeds to Step S5.
On the other hand, in Step S14, the CPU 106 determines whether the credit amount C is at least the total bet amount in a previous game. In other words, the CPU 106 determines whether it can start a game in response to a pushing operation executed on the spin repeat bet switch 24. Specifically, in a case where the spin repeat bet switch 24 has been pushed, and accordingly, in a case where the operation signal has been input from the switch 24, the CPU 106 reads the credit amount C and the bet amount bet to each of the active pay lines L1 to L9 in the previous game stored in the predetermined memory areas of the RAM 110. Then, the CPU 106 determines whether the credit amount C is at least the total bet amount bet in the previous game based upon the relation between the credit amount C and the bet amount thus read. When the CPU 106 determines that the credit amount C is less than the total bet amount (NO in Step S14), the CPU 106 terminates the routine without any processing, since it cannot start a game. On the other hand, in a case where determination has been made that the credit amount C is at least the total bet amount bet in the previous game (in a case of “YES” in the determination processing in Step S14), the CPU 106 subtracts the total bet amount bet in the previous game from the credit amount C, and stores the subtracted value in a predetermined area of the RAM 110. Subsequently, the CPU 106 moves the processing to Step S5.
In Step S5, the CPU 106 performs processing for jackpot and moves the processing to Step S6.
In Step S6, the CPU 106 performs processing for determining a combination of symbols. A specific description is provided below regarding the combination determination processing.
In the combination determination processing, the CPU 106 first determines the combinations of the symbols along the active pay lines when they are stationary. Specifically, the CPU 106 issues a command for the random number generator 112 to generate a random number, thereby extracting a random number in a predetermined range (in a range of “0” to “65535” in the present embodiment) generated by the random number generator 112. The CPU 106 stores the random number thus extracted in a predetermined memory area of the RAM 110. It should be noted that a description is provided in the present embodiment regarding an arrangement in which the random number is generated by the random number generator 112, which is a separate component from the CPU 106. In addition, an arrangement may be made in which the random number is generated by computation processing by the CPU 106 without involving the random number generator 112. The CPU 106 reads a random number table for a basic game (see FIG. 9), and a payout table (see FIG. 10) for a basic game, each of which is stored in the ROM 108. Then, the CPU 106 stores the random number table for a basic game and the payout table for a basic game, thus read in a predetermined memory area of the RAM 110. It should be noted that the CPU 106 controls display of the symbols when they are stationary for each reel based upon the random number table for a basic game. Furthermore, the CPU 106 reads the random number table for a basic game and the payout table for a basic game stored in the predetermined area of the RAM 110. Then, the CPU 106 determines the combination of the symbols when they are stationary with respect to the active pay lines with reference to the random number table for a basic game, using the random number stored in the predetermined memory region of the RAM 110 as a parameter. Upon determination of specified combinations for providing an award, the CPU 106 stores the specified combination data for providing an award thus determined in a predetermined memory area of the RAM 110. Then, the CPU 106 reads the random number and the specified combination data for providing an award stored in the predetermined memory area of the RAM 110, and determines the combination of the symbols displayed to be stationary based upon the random number and the specified combination data for providing an award thus read. In this stage, a symbol arrangement table (see FIG. 7) stored in the ROM 108 is read by the CPU 106. The symbol arrangement table thus read is stored in a predetermined memory area of the RAM 110, and used as reference data. The CPU 106 stores the data for the stationary symbols thus determined in a predetermined memory area of the RAM 110. Alternatively, an arrangement may be made in which the stationary symbols are determined for each reel using the random number table for a basic game.
Upon determination of the combination of the symbols when stationary with respect to the active pay lines, the CPU 106 determines whether the combination of the symbols when they are stationary with respect to the active pay lines matches any one of the specified combinations for providing an award. In a case where the combination of the symbols when they are stationary with respect to the active pay lines matches any one of the specified combinations for providing an award, the CPU 106 activates a flag, which indicates that the player has won the award that corresponds to the kind of specified combination for providing an award, in order to provide the award that corresponds with the specified combination of symbols with respect to the active pay lines for providing the award. The activated flag, which indicates the player has won an award, is stored in a predetermined area of the RAM 110 according to the instruction from the CPU 106. On the other hand, in a case where the combination of the stationary symbols with respect to the active pay lines matches any one of the other combinations, i.e. the losing combinations, the CPU 106 does not activate the flag which indicates that the player has won an award. Subsequently, the CPU 106 moves the processing to Step S7.
Here, a random number table for basic games shown in FIG. 9 is explained. In the random number table for a basic game, a range of random numbers and the probability of winning are registered in association with each of the specified winning combinations. In processing for determining a symbol combination, for example, in a case where a random number lying in a range of 0 to 299 is extracted from a range of numbers of 0 to 65535, the slot machine 13 internally determines to generate a bonus combination as the final results of the basic game. In other words, the probability is “300/65536” that the combination of the stationary symbols matches any one of the bonus combinations. On the other hand, in a case where a random number lying in a range of 10000 to 65535 is extracted from a range of numbers of 0 to 65535, the slot machine 13 internally determines to generate other combinations, i.e. losing combinations, as the final results of the basic game. In other words, the probability is “55536/65536” that the combination of the stationary symbols matches any one of the losing combinations.
FIG. 10 shows a payout table for a basic game. In the payout table for a basic game, the coin amount to be paid out is registered in association with each specified combination for providing an award for each credit amount bet on one game. Therefore, let us consider a stage in which a determination is made whether the combination thus generated matches any one of the specified combinations for providing an award. In this stage, let us consider a case in which the combination thus generated matches the combination “Wild”. In this case, in a case where the credit amount bet is “1”, 50 coins are paid out. In a case where the credit amount bet is “2”, 100 coins are paid out. In a case where the credit amount bet is “3”, 150 coins are paid out.
Referring to FIG. 8 again, in the following Step S6, the CPU 106 instructs the video reels 3A to 3E to start to rotate. Specifically, the CPU 106 displays an image which shows the video reels 3A to 3E rotating, in sequence or simultaneously, based upon the symbol arrangement table stored in the RAM 110.
Upon displaying the image which shows the video reels 3A to 3E starting to rotate, the CPU 106 waits for a predetermined period of time to elapse (Step S8) After the predetermined period of time has elapsed (in a case of “YES” in the determination processing in Step S7), the CPU 106 instructs the video reels 3A to 3E to automatically stop rotating (Step S8) Specifically, the CPU 106 displays an image which shows the video reels 3A to 3E stopping rotation sequentially or simultaneously such that the stationary symbols, which correspond to the specified combinations for providing an award determined in Step S6, are displayed within a display region that has a visually interactive relationship with the player. Subsequently, the flow proceeds to Step S10 according to the instruction from the CPU 106.
In the following Step S10, the CPU 106 determines whether a predetermined symbol combination has been formed based upon the results of the combination determination processing performed in Step S6. Specifically, the CPU 106 makes this determination based upon the state of the flag that indicates whether the player has won an award with respect to the active pay lines stored in the predetermined memory area of the RAM 110. In a case where the flag, which indicates that the player has won an award, has not been activated, i.e. in a case where the symbol combination matches any one of the “other” combinations, which are combinations other than the specified combinations for providing an award (in a case of “NO” in the determination processing in Step S10), the CPU 106 determines that the specified combination for providing an award has not been formed, and ends this routine. On the other hand, in a case where the flag, which indicates that the player has won an award, has been activated, i.e. in a case where the symbol combination matches any one of the combinations other than the “other” combinations (in a case of “YES” in the determination processing in Step S9), the processing proceeds to Step S10 according to the instruction from the CPU 106.
In the following Step S10, the CPU 106 determines whether the symbol combination thus formed based upon the combination determination processing performed in Step S5 is a bonus combination. Specifically, the CPU 106 makes this determination based upon the state of the flag that indicates whether the player has won an award with respect to the active pay lines stored in the predetermined memory area of the RAM 110. In a case where the flag indicating winning of an award by the player has been activated and the specified combination for providing an award is a “bonus” combination, the processing proceeds to Step S12 according to the instruction from the CPU 106. If not, the flow proceeds to Step S13.
In the following Step S12, the CPU 106 executes free game receive/defer select processing. Upon finishing the processing in Step S12, the CPU 106 terminates the routine.
In a case where the flow has proceeded to Step S12, the CPU 106 pays out an amount of coins corresponding to the specified combination for providing an award. Specifically, the CPU 106 calculates the amount of coins to be paid out for the specified combination for providing an award, with reference to the payout table for a basic game (FIG. 10). The CPU 106 reads the credit amount stored in the predetermined memory area of the RAM 110. Then, the CPU 106 calculates the sum total amount of coins to be paid out thus calculated and the credit amount thus read, and stores the sum thus calculated in a predetermined memory area of the RAM 110. The CPU 106 displays the sum thus stored on the credit amount display unit 49. Subsequently, the CPU 106 terminates the routine.
Referring to FIG. 11, jackpot processing is explained.
In Step S21, the CPU 106 determines whether or not the portion of the credit amount bet has reached the predetermined amount. In a case where the CPU 106 determines that the portion of the credit amount bet has reached the predetermined amount, the CPU 106 moves the processing to Step S22, and in a case where the CPU 106 determines that it has not reached the predetermined amount, the CPU 106 terminates the routine. Specifically, the CPU 106 compares the portion of the credit amount bet stored in the predetermined area with the predetermined amount.
In Step S22, the CPU 106 executes the read processing of the number of times jackpot awards deferred, and moves the processing to Step S23. Specifically, the CPU 106 reads the number on the counter for counting the number of times the jackpot has been deferred in the predetermined memory area in RAM 110.
In Step S23, the CPU 106 determines whether or not the player receives the jackpot award, and moves the processing to Step S24. Specifically, the CPU 106 determines whether or not the player receives the jackpot award with reference to a random number table for determining a jackpot award, which is described below in FIG. 12 through FIG. 14.
Here, a random number table for determining a jackpot award shown in FIG. 12 is explained. The random number table for determining the jackpot award (not deferred) is referred to when the CPU 106 determines whether or not to provide the jackpot award in a case where the number of times deferred jackpot is 0. For example, in a case where the random number generated by the random number generator 112 is “8000”, the number belongs to a range of random numbers “0 to 9999”, and thus the CPU 106 determines to provide the jackpot award.
Although the random number table for determining the jackpot award (deferred once) shown in FIG. 13 is similar to the random number table for determining the jackpot award (not deferred) shown in FIG. 12, the random number table for determining the jackpot award (deferred once) shown in FIG. 13 has a higher probability of providing a jackpot award than the random number table for determining the jackpot award (not deferred) shown in FIG. 12, since the number of times jackpot awards have been deferred is higher.
Although the random number table for determining the jackpot award (deferred twice) shown in FIG. 14 is similar to the random number table for determining the jackpot award (deferred once) shown in FIG. 13, the random number table for determining the jackpot award (deferred twice) shown in FIG. 14 has higher a probability of providing a jackpot award than the random number table for determining the jackpot award (deferred once) shown in FIG. 13, since the number of times jackpot awards have been deferred is higher.
Referring to FIG. 11 again, in Step S24, the CPU 106 determines whether or not to provide the jackpot award. In a case where the CPU 106 determines to provide the award, the CPU 106 moves the processing to Step S25, and in a case where the CPU 106 determines not to provide the award, the CPU 106 terminates the routine.
In the following Step S25, the CPU 106 receives a input for selecting of whether a player receives or defers the award, and moves processing to Step S26. Specifically, the CPU 106 receives a signal of the input for selecting via the touch panel 32.
In the following Step S26, the CPU determines whether the CPU has received the input for selecting to defer the award. In a case where the CPU receives the input for selecting to defer the award, the processing is moved to Step S27, and in a case where the CPU receives the input for selecting of receiving the award, the processing is moved to Step S28. Specifically, the CPU 106 determines whether a player receives or defers the free game according to a signal of the input for selecting received via the touch panel 32.
In the following Step S27, the CPU 106 adds one to the number of times the jackpot has been deferred. Specifically, the CPU 106 adds one to the read number of times the jackpot has been deferred, and stores the number in the predetermined memory area in the RAM 110. Upon finishing the processing in Step S27, the CPU 106 terminates the routine.
In Step S28, the CPU 106 provides the award according to the levels of awards which are corresponding to the number of times the jackpot has been deferred. Specifically, the CPU determines the amount of credits corresponding to the number of times the jackpot has been deferred with reference to the payout table for the jackpot, which is described below in FIG. 15.
Here, the payout table for a jackpot in FIG. 15 is explained. This payout table for a jackpot is referred to when the CPU 106 provides an award according to the level of awards which are corresponding to the number of times the jackpot has been deferred. For example, in a case where jackpot has been deferred once, the CPU 106 pays out 200 credits.
FIG. 16 illustrates an example of the rendered image. According to FIG. 16, while the game is proceeding, the number of times the jackpot has been deferred at the current state is displayed within a display region 81 and the credit amount corresponding to the number of times the jackpot has been deferred is displayed within a display region 82. The CPU 106 displays the image on the liquid crystal display 30 via the display/input controller 140.
FIG. 17 illustrates the example of the rendered image. According to FIG. 17, in a case where the CPU 106 determines to provide the jackpot award in Step S24 in FIG. 11, “YOU WON JACKPOT!” is displayed and the button 82 “RECEIVE” and the button 83 “DEFER” are displayed. The CPU 106 displays the image on the liquid crystal display 30 via a display/input controller 140.
Referring to FIG. 11, free game receive/defer select processing is explained.
In Step S31, the CPU 106 executes the read processing of the number of times a free game has been deferred, and moves to Step S32. Specifically, the CPU 106 reads the number on the counter for counting the number of times a free game has been deferred in the predetermined memory area in the RAM 110.
In Step S32, the CPU 106 receives a signal of input for selecting of whether to receive or defer a free game, and moves to Step S33. Specifically, the CPU 106 receives the signal of the input for selecting via the touch panel 32.
In Step S33, the CPU 106 determines whether or not the CPU 106 has received the input for selecting to defer the free game. In a case where the CPU 106 receives the input for selecting to defer, the processing is moved to Step S34, and in a case where the CPU 106 receives the input for selecting of receiving, the processing is moved to Step S28.
Specifically, the CPU 106 determines whether a player receives or defers the free game according to a signal of the input for selecting received via the touch panel 32.
In Step S34, the CPU 106 adds one to the number of times deferred. Specifically, the CPU 106 adds one to the read number of a free game having been deferred, and stores the number in the predetermined memory area in the RAM 110. Upon finishing the processing in Step S34, the CPU 106 terminates the routine.
In Step S35, the CPU 106 provides the award according to the level of awards which are corresponding to the number of times a free game has been deferred. Specifically, the CPU 106 executes the free game a number of times corresponding to the number of times a free game has been deferred with reference to the multiplication factor/a number of times table for a free game, which is described below in FIG. 21. In addition, the CPU 106 provides the award according to a multiplication factor corresponding to the number of times deferred, a random number table for a free game which is described below in FIG. 19, and a payout table for a free game which is described below in FIG. 20.
Here, a random number table for free games in FIG. 19 is explained. In the random number table for a free game, a range of random numbers and the probability of winning are registered in association with each symbol. In symbol combination determination processing, for example, in a case where a random number lying in a range of 3100 to 3899 is extracted from a range of random numbers of 0 to 65535, the slot machine 13 internally determines to generate an “Ace” combination as the final results of the free game. In other words, the probability is “800/65536” that the combination of the stationary symbols matches any one of the “Ace” combinations.
FIG. 20 shows a payout table for a free game. In the random number table for a free game, the amount of coins that should be paid out for each credit amount bet in one game are registered in association with each symbol. Therefore, when the CPU 106 determines whether the combination thus generated matches any one of winning combinations for providing an award, for example, in a case where the combination thus generated matches the combination “Ace” and in a case where the credit amount bet is “1”, 10 coins are paid out. In a case where the credit amount bet is “2”, 15 coins are paid out. In a case where the credit amount bet is “3”, 20 coins are paid out.
Furthermore, the multiplication factor table/number of times table for free games shown in FIG. 21 is explained. This multiplication factor table for a free game is referred to when the CPU 106 provides the award according to the level of awards which are corresponding to the number of times the free games has been deferred. For example, in a case where the number of times a free game has been deferred is one, the multiplication factor of the award is “double”, and the number of times performing free games turns out to be “30 times”.
The CPU 106 extracts the credit amount corresponding to the combination of symbols from a payout table for a free game which is described above in FIG. 20, and pays out double the amount of credits.
FIG. 22 illustrates an example of the rendered image. According to FIG. 22, while the game is proceeding, the number of times the free games have been deferred at the current state is displayed within a display region 82, a multiplication factor corresponding to the number of times the free games have been deferred is displayed within a display region 81, and the combination of bonus symbol, which is a condition for winning free games, is displayed. The CPU 106 displays the image on the liquid crystal display 30 via the display/input controller 140.
FIG. 23 illustrates an example of the rendered image. According to FIG. 23, in Step S11 shown in FIG. 8, in a case where the combination of symbols for a bonus is formed, “YOU WIN A FREE GAME” is displayed and the button 83 “RECEIVE” and the button 84 “DEFER” are displayed. The CPU 106 displays the image on the liquid crystal display 30 via the display/input controller 140.
Although in the present embodiment, the player can not receive a jackpot or a free game until the next time the player receives a jackpot or a free game in a case where a player defers a jackpot or a free game, the present embodiment is not limited thereto, and a player may cancel deferring and receive a jackpot or a free game.
In addition, although in the present embodiment, an example where the more a player defers a jackpot or a free game, the more a player receives awards is explained, the present embodiment is not limited thereto, and in a case where the predetermined combination of symbols is formed or the predetermined number of predetermined symbols are displayed, the number of times deferred may be reset (for example, 0) to a predetermined number.
Furthermore, although in the present embodiment, an example is explained for a case in which the portion of the credit amount bet has reached the predetermined amount, the CPU 106 determines whether or not to provide the jackpot award randomly, and in a case where the predetermined combination of symbols is formed, etc., a jackpot award may be provided when the predetermined condition is satisfied.
In addition, although in the present embodiment, an example applied to a video reel slot machine is explained regarding the present invention, the present embodiment is not limited thereto, and the present invention may be applied to a mechanical slot machine, for example.
Furthermore, although in the present embodiment, an example using a slot machine (a so-called casino machine) in which a reel is automatically stopped after being rotated without using a stop button is explained regarding the present invention, the present embodiment is not limited thereto, and the present invention may be applied to a slot machine (a so-called Pachinko-slot machine) in which reels are stopped in the order by which a player stops the reels by hand using the stop button, for example.
While the embodiments according to the present invention have been described as mentioned above, it is understood that many changes and modifications may be made therein without departing from the spirit and scope of the present invention.
