Definitions
- the present invention relates to a gaming machine such as a slot machine in which a game is conducted using a game media (game valuable) such as a coin and the like, a game control method for the gaming machine, and a game system comprising the gaming machine and a control device.
- a gaming machine such as a slot machine in which a game is conducted using a game media (game valuable) such as a coin and the like
- a game control method for the gaming machine such as a coin and the like
- a game system comprising the gaming machine and a control device.
- a game is played by inserting various kinds of game media such as a coin, cash and the like into a gaming machine.
- game media such as a coin, cash and the like
- Each gaming machine pays out a dividend to a player according to a prize wining state (a result of playing the game) generated while the game is in progress.
- a credit spent in each slot machine is partly reserved and in a case where the reservation reaches a predetermined amount, one of the slot machines provides a so-called “jackpot” paying out a big amount, which is not paid out in an ordinary hit (JP-A 2003-117053).
- a hit in each machine usually occurs on a preset probability and a player advances a game with expectation of the hit to be encountered.
- One of the slot machines has a chance to hit a jackpot at a timing in a lottery different from a common lottery in which a hit based on the above-mentioned probability is set in the slot machines.
- plural casinos are interconnected in a network in order to increase a payout amount in a jackpot.
- a system has been available in which a host computer and plural gaming machines are interconnected on a network and the generating of a bonus in the gaming machines is controlled by the host computer (U.S. Pat. No. 5,820,459).
- the host computer gives a bonus qualification to a gaming machine in which the number of inserted coins reaches a predetermined number.
- the host computer transmits a command to one gaming machine selected from gaming machines having bonus qualification, when a value of the bonus pool reaches a predetermined threshold value.
- the gaming machine which received the command is enabled to play a bonus game high in gambling characteristic.
- a chance to acquire the profit of a bonus game is one of gaming machines in which a total number of inserted coins reaches a predetermined number.
- a chance to acquire the profit of a bonus game is not always given to a player having spent many coins. Therefore, in the system described in U.S. Pat. No. 5,820,459, there has arisen a case where a player having spent many coins cannot secure the profit of a bonus game and another player who has just started the game acquires a bonus game profit, in a similar way to that in a slot machine described in JP-A 2003-117053.
- the present invention has been made in light of the above-mentioned problems and it is an object of the present invention to provide: a gaming machine capable of preventing a player who has spent many of the game media such as coins from feeling unpleasant against a game, building up a distrust thereto, or losing interest in or a concern on the game; a control device; and a game system.
- the present invention provides the following configuration:
- a gaming machine comprising:
- winning combination determination means for determining a winning combination by a lottery

As a result, it can be prevented for a player who has spent many of the game media from feeling unpleasant against the game, building up distrust thereto, or losing interest in or a concern on the game.
- the present invention provides the following configuration:
- winning combination determination means for determining a winning combination by a lottery
- the control device when the number of games counted by the control device reaches a set value that is set as an object of comparison with the number of games, the second special game state in which a probability of generating the first special game state is set relatively high is generated.
- the second special game state is necessarily generated as long as the game is played such that the number of games reaches the set value, and in the first special game state generated during the second special game state, a player can surely receive the return for the fact that a game is played until the number of games reaches a set value. Therefore, it can be prevented for a player who has spent many of the game media from feeling unpleasant against the game, building up distrust thereto, or losing interest in or a concern on the game.

- the option “INSURANCE” corresponds to the with-insurance mode.
- a predetermined number of credits for example, number of credits equivalent to 1 dollar
- a note or a coin equivalent to the number of credits may be directly inserted.
- the return mode flag is set to the state “ON” and a game state shifts to the return mode. In the payout return mode, the probability of the generating of the bonus game becomes relatively high, and the return mode is continued until the bonus game is generated.
- a game in the with-insurance mode, a game can be played in a state where an insurance is carried for compensating all or part of a loss arising in a case where no bonus game has arisen for a long time.

- step S 10 If it is determined that the spin button 23 has not been turned ON, the process returns to step S 10 . Note that in a case where the spin button has not been turned ON (for example, in a case where a command of terminating a game has been inputted without turning ON the spin button), the main CPU 41 cancels a result of the subtracting processing in step S 11 .
- step S 10 after a coin is BET (step S 10 ), a processing for conducting subtraction on the number of credits (step S 11 ) is conducted prior to the determination on whether or not the spin button has been turned ON (step S 12 ).

- the main CPU 41 determines whether or not a bonus game trigger has been established, that is whether or not “APPLE” is stop displayed in the display window 15 (step S 15 ). If it is determined that the bonus game trigger has been established, the main CPU 41 (processing device) reads a program for conducting a bonus game from RAM 43 (storage device) to execute a bonus game processing (step S 16 ). Here, the first special game state is generated. Detailed description of the bonus game processing will be given later by making reference to FIG. 16 .

- description will be given of a case where random numbers are generated on a program (a case where so-called software random numbers are used).
- a random number generator may be used, and random numbers may be extracted therefrom (so-called hardware random numbers may be used).

(see FIG. 3 ) for each of the reels 14 (step S 32 ).
- the code Nos. of the reels 14 correspond to code Nos. of the symbols stop displayed on the winning line L.
- the main CPU 41 determines code Nos. of the reels 14 to thereby determine a winning combination. For example, in a case where code Nos. of the reels 14 are determined “00”, “00” and “00”, it means that the main CPU 41 determined a winning combination as “JACKPOT”. Based on the code Nos. determined for each of the reels, a reel rotating control processing which will be described later is conducted. On this occasion, the main CPU 41 functions as winning combination determination means.
- FIG. 12 is a figure describing a relationship among winning combinations of plural kinds, establishment possibility of each winning combination and the number of coin-out in the present embodiment.
- the establishment possibilities of each of the winning combinations shown in FIG. 12 are of a case where a payout rate is set to 88% in a game other than a bonus game.
- the establishment possibilities shown in the figure show possibilities of the establishment of each of the shown winning combinations in such a case that code Nos. of each of the reels 14 are determined based on the selected three random number values by referring to a symbol weighting determination data. In other words, the random number values are not made to correspond to each of the winning combinations.
- An establishment possibility of a bonus game trigger is 0.5%. If a player hits the bonus game trigger, three “APPLE” symbols are stop displayed on the winning line L and a bonus game is generated. In the bonus game, executed is a free game of which the number of games is determined by a lottery.
- JACKPOT 7 An establishment possibility of “JACKPOT 7” is 0.5%. If the winning combination has been established, three “JACKPOT 7” symbols are stop displayed on the winning line L, and 30 coins per one coin-in are paid out. The lower the establishment possibility of the winning combination is, the higher the number of coin-out is set. When a combination of symbols stop displayed is not hitting any of the winning combinations shown in FIG. 12 , this is a failure, and there is no coin-out.
- FIG. 13 is a flowchart showing a reel rotating control processing called and executed in step S 15 of the subroutine shown in FIG. 10 .
- This processing is a processing conducted between the main CPU 41 and the sub CPU 61 .
- the main CPU 41 transmits to the sub CPU 61 a start signal that starts the rotating of reels (step S 40 ).
- the sub CPU 61 conducts a reel rotating processing when it receives the start signal from the main CPU 41 (step S 51 ).
- the sub CPU 61 supplies a pulse to the motor driving circuit 62 .
- the pulse outputted from the sub CPU 61 is amplified by the driver 64 and supplied to each of the stepping motors 70 ( 70 L, 70 C and 70 R).
- the stepping motors 70 rotate, there by making the reels 14 ( 14 L, 14 C and 14 R) to rotate.
- a stepping motor 70 is a 1-2 phase excitation type stepping motor which has a step angle of 0.9 degree and requires the number of steps of 400 for one rotation. Hence, if 400 pulses are supplied to the stepping motor 70 , the reels 14 rotate once.
- the sub CPU 61 supplies to the motor driving circuit 62 pulses at a lower frequency, and the pulse frequency is gradually raised. A rotational speed of the reels 14 is thereby increased.
- the pulse frequency is controlled to be constant. As a result, the reels 14 rotate at a constant speed.
- FIGS. 14A to 14 D are side views for describing a rotating operation of a reel 14 .
- a semicircular metal plate 14 a is attached to the side surface of a reel 14 .
- the metal plate 14 a rotates together with the reel 14 .
- Twenty two symbols are depicted on the circumferential surface of the reel 14 .
- Three symbols of the twenty two symbols depicted on the circumferential surface of the reel 14 can be visually recognizable through the display window 15 formed in front of the reel 14 .
- the arrow mark of a heavy line in the figure indicates a rotating direction of the reel 14 .
- a proximity sensor 65 a is provided on the side of the reel 14 .
- the proximity sensor 65 a is used to detect the metal plate 14 a .
- the proximity sensor 65 a does not rotate nor move even if the reel 14 rotates.
- FIG. 14A shows a position of the meal plate 14 a when the metal plate 14 a starts being detected by the proximity sensor 65 a (hereinafter also referred to as a position A). If the reel 14 rotates when the metal plate 14 a is at the position A, the metal plate 14 a moves to a position shown in FIG. 14B .
- FIG. 14B shows a position of the metal plate 14 a when the metal plate 14 a is being detected by the proximity sensor 65 a (hereinafter also referred to as a position B). If the reel 14 rotates when the metal plate 14 a is at the position B, the metal plate 14 a moves to a position shown in FIG. 14C .
- FIG. 14C shows a position of the metal plate 14 a when the metal plate 14 a will no longer be detected by the proximity sensor 65 a (hereinafter also referred to as a position C).
- FIG. 14D shows a position of the metal plate 14 a when the metal plate 14 a is not detected by the proximity sensor 65 a (hereinafter also referred to as a position D). If the reel 14 further rotates, a position of the metal plate 14 a returns to the position A. As described above, together with the rotating of the reel 14 , the metal plate 14 a changes its position in the order from the position A, to the position B, to the position C, to the position D, to the position A and so forth.
- the proximity sensor 65 a constitutes an index detecting circuit 65 (see FIG. 3 ).
- a state of the index detecting circuit 65 is “High” during the period when the metal plate 14 a moves from the position A to the position B and to the position C
- a state of the index detecting circuit 65 is “Low” during the period when the metal plate 14 a moves from the position C to the position D and to the position A.
- the sub CPU 61 assigns a rise from “Low” to “High” as an index (origin) 1 and a fall from “High” to “Low” as an index (origin) 2 to thereby recognize the rotating position of the reel 14 .
- the main CPU 40 after transmitting in step 40 a start signal to the sub CPU 61 , executes representation to be executed while the reels are rotating (step S 41 ).
- the process is a processing which conducts display of an image on the lower image display panel 16 and output of a sound from the speaker 29 over a period (for example, 3 seconds) determined according to a result and the like of the lottery processing (step S 13 in FIG. 10 ).
- the main CPU 40 determines whether or not it is the timing at which a command is to be issued so as to stop the rotating of the reel 14 (step S 42 ).
- the timing at which a command is issued so as to stop rotation of a reel 14 is a timing before the time when the representation to be executed while the reels are rotating is terminated, which is an interval having the minimum time necessary for stopping the rotating of the reel 14 . Note that the minimum time necessary for stopping the rotating of the reel 14 is determined in advance.
- step S 42 If it is determined in step S 42 that it is not the timing at which the command to stop the rotating of the reel 14 is to be issued, the process returns to the processing in step S 42 and the representation to be executed while the reels are rotating continues to be conducted. On the other hand, if it is determined in step S 42 that it is the timing at which the command to stop the rotating of the reel 14 is to be issued, the main CPU 41 transmits to the sub CPU 61 a code No. of the reel which is stored in RAM 43 (step S 43 ). When the sub CPU 61 receives a code No. of the reel from the main CPU 41 , the code No. is converted to a stopping position of the reel (the number of steps) from an index, based on a correspondence table between the number or steps and the code Nos. stored in ROM (not shown in the figure) included in the sub CPU 61 (step S 52 ).
- FIG. 15 is a schematic diagram showing a correspondence table between the number of steps and the code No. Each of the code Nos. are related to an index and the number of steps.
- Each code No. corresponds to the symbols depicted on the circumferential surfaces of the reels 14 (see FIG. 3 ) and symbols of code Nos. “00” to “10” correspond to the index 1 . Moreover, symbols of code Nos. “11” to “21” correspond to the index 2 .
- the number of steps in the correspondence table shown in FIG. 15 is the number of steps with the index 1 as a reference. For example, if a code No. is “08”, a stopping position of the reel is at 145 steps from the index 1 . If a code No. is “12”, a stopping position of the reel is at 218 steps from the index 1 .
- the sub CPU 61 executes a reel stopping processing (step S 53 ).
- the sub CPU 61 detects a rise in the index detecting circuit 65 from “Low” to “High” (the index 1 ) on each of the reels 14 , and supplies to the motor driving circuit 65 pulses corresponding to the number of steps which were converted in step S 52 from a code No. at a timing at which the index 1 is detected, and supply of pulses is ceased there after.
- step S 52 when, in step S 52 , the stopping positions of the reels are determined to be 145 steps from the index 1 , the sub CPU 61 supplies 145 pulses to the motor driving circuit 65 at a timing at which the index 1 is detected, and the supply of pulses is terminated thereafter. Furthermore, when, in step S 52 , the stopping positions of the reels are determined to be 218 steps from the index 1 , the sub CPU 61 supplies 218 pulses to the motor driving circuit 65 at a timing at which the index 1 is detected. As a result, the reels 14 stop at the code No. determined in step 32 of FIG. 11 and the combination of symbols corresponding to the winning combination determined in step S 32 of FIG. 11 is stop displayed on the winning line L. On the other hand, the main CPU 41 terminates the representation to be executed while the reels are rotating. After the processing in steps S 44 and S 53 are over, the present reel rotating control processing is completed.
- step S 43 when an index corresponding to the code No. transmitted in step S 43 is different from an index detected by the index detecting circuit 65 when the rotating of the reels 14 stop, this means that an out-of-order state occurred on the reels 14 ; therefore, the main CPU 41 conducts a processing for displaying an error message on the lower image display panel 16 to temporarily stop a game.
- the game is temporarily stopped.

Thus, when a bonus game is hit during the bonus game, a remaining number of bonus games increases. More specifically, for example, in a case where a game state shifts to 20 bonus games for the first time, and hits 17 bonus games upon conducting 12 of the bonus games, another 25 bonus games (20 bonus games ⁇ 12 bonus games+17 bonus games) are to be conducted.

Since the processing is similar to the processing in step S 18 and description thereof has already been given, the description of the present processing is omitted herein.
- step S 66 or S 68 the main CPU 41 reads the number T of bonus games stored in RAM 43 , and one bonus game is subtracted from the read number T of bonus games. The number T of bonus games after the subtraction is again stored into RAM 43 (step S 69 ).
- the main CPU 41 determines whether or not the number T of bonus games reaches the number of games determined in step S 60 (step S 70 ). More specifically, it is determined whether or not the number T of games stored in RAM 43 has become 0, and if the number T of games is not 0, that is, if it is determined that the number of bonus games played does not reach the number of games which were determined in step S 60 , the process returns to step S 61 and the above-mentioned processing is repeated.
- a number-of-games reset signal is transmitted to the control device 200 (step S 71 ), and the present subroutine is completed thereafter.
- the number-of-games reset signal includes the gaming machine identification information of the gaming machine 10 , and CPU 201 of the control device 200 , when receiving the number-of-games reset signal, resets to 0 the number of games of which is stored in the hard disc drive 205 by being made to correspond to the gaming machine identification information included in the number-of-games reset signal.

- the main CPU 41 transmits by the communication interface 44 the number of coin-in and the number of coin-out stored in RAM 43 together with the gaming machine identification number to the control device 200 through the communication line 101 (step S 90 ).
- the number of coin-in and the number of coin-out transmitted to the control device 200 from the gaming machine 10 are those of the game concerned.
- the processing in step S 90 is a processing in which the main CPU 41 (processing device) transmits the identification information of the gaming machine 10 stored in the main RAM 43 (storage device) to the control device 200 through the communication line 101 , each time a game is played.
- the main CPU 41 functions as means for transmitting the identification information of the gaming machine 10 to the control device 200 through the communication line 101 .
- the CPU 201 of the control device 200 when receiving from the gaming machine 10 the number of coin-in, the number of coin-out and the gaming machine identification number through the communication line 101 by the communication interface 204 , updates the number of games, the accumulative number of coin-in and the accumulative number of coin-out corresponding to the received gaming machine identification number (step S 100 ), by choosing the data, which are made to correspond to each of the gaming machine identification numbers, of the number of games, the accumulative number of coin-in, the accumulative number of coin-out stored in the hard disc drive 205 (see FIG. 6 ).
- CPU 201 determined whether or not the number of games after the updating has reached the set value (step S 101 ). If it is determined that the number of games after the updating has not reached the set value, the subroutine is terminated.
- step S 101 determines whether the number of games after the updating has reached the set value.
- CPU 201 transmits a return command signal through the communication line 101 by the communication interface 204 to the gaming machine 10 in which the number of games has reached the set value (step S 103 ). Thereafter, CPU 201 resets to 0 the number of games stored in the hard disc drive 205 which are made to correspond to the gaming machine-identification number of the gaming machine 10 (step S 104 ). Thereafter, the present processing is terminated.
- the main CPU 41 of the gaming machine 10 when receiving the return command signal transmitted from the control device 200 in step S 103 , sets the return mode flag to the state “ON” (step S 91 ).
- the processing in step S 91 is a processing for receiving a command signal transmitted from the control device 200 when the number of games accumulatively counted by the control device 200 based on the identification information of the gaming machine 10 reaches a set value that is an object of comparison with the number of games.
- the main CPU 41 functions as means for receiving a command signal transmitted from the. control device 200 . Thereafter, the present processing is terminated.
- the present invention is, however, not limited to this example.
- the second special game state may be generated (the game state shifts to the return mode). This is because in such a case, a player can be urged to insert game media up to the upper limit and a facility such as a casino and the like can increase a profit.
- the second special game state is generated when the number of inserted game media is at the upper limit value
- the second special game state maybe generated not when the number of games reaches the set value, but when the number of inserted game media is at the upper limit value for a game played by a player when the number of games in which insertion of game media is conducted to the upper limit value reaches a set value. This is because, in such a case, it can be prevented from a small number of game media to be inserted in a game, thereby leading to a fact that the second special game state is generated by the spending of only a small number of game media in total.

Description
- This application claims benefit of priority based on PCT/JP2005/015810 filed on Aug. 30, 2005. The contents of this application are incorporated herein by reference in their entirety.
- 1. Field of the Invention
- The present invention relates to a gaming machine such as a slot machine in which a game is conducted using a game media (game valuable) such as a coin and the like, a game control method for the gaming machine, and a game system comprising the gaming machine and a control device.
- 2. Discussion of the Background
- Conventionally, in a facility in which gaming machines such as a slot machine are installed, a game is played by inserting various kinds of game media such as a coin, cash and the like into a gaming machine. Each gaming machine pays out a dividend to a player according to a prize wining state (a result of playing the game) generated while the game is in progress.
- In a casino where plural slot machines are installed, a credit spent in each slot machine is partly reserved and in a case where the reservation reaches a predetermined amount, one of the slot machines provides a so-called “jackpot” paying out a big amount, which is not paid out in an ordinary hit (JP-A 2003-117053). In such slot machines, a hit in each machine usually occurs on a preset probability and a player advances a game with expectation of the hit to be encountered. One of the slot machines has a chance to hit a jackpot at a timing in a lottery different from a common lottery in which a hit based on the above-mentioned probability is set in the slot machines. Generally, plural casinos are interconnected in a network in order to increase a payout amount in a jackpot.
- Furthermore, a system has been available in which a host computer and plural gaming machines are interconnected on a network and the generating of a bonus in the gaming machines is controlled by the host computer (U.S. Pat. No. 5,820,459). In this system, not only is the number of coins inserted into each gaming machine added up, but part of a total number of inserted coins in the plural gaming machines are separately added up as a bonus pool. The host computer gives a bonus qualification to a gaming machine in which the number of inserted coins reaches a predetermined number. The host computer transmits a command to one gaming machine selected from gaming machines having bonus qualification, when a value of the bonus pool reaches a predetermined threshold value. The gaming machine which received the command is enabled to play a bonus game high in gambling characteristic.
- In a slot machine described in JP-A2003-117053, however, it is a player who plays a game in a gaming machine selected in a lottery that enjoys a profit from a jackpot. Hence, there has arisen a case where a player having spent many coins cannot enjoy a jackpot at all, but another player who has just started the game acquires a jackpot profit.
- In the system described in U.S. Pat. No. 5,820,459 as well, a chance to acquire the profit of a bonus game is one of gaming machines in which a total number of inserted coins reaches a predetermined number. A chance to acquire the profit of a bonus game is not always given to a player having spent many coins. Therefore, in the system described in U.S. Pat. No. 5,820,459, there has arisen a case where a player having spent many coins cannot secure the profit of a bonus game and another player who has just started the game acquires a bonus game profit, in a similar way to that in a slot machine described in JP-A 2003-117053.
- In the system described in U.S. Pat. No. 5,820,459, part of the number of inserted coins in each of plural gaming machines is added up as a bonus pool. Hence, in a case where an operation rate of the gaming machines in the system is low, a player, who has spent many of coins, has had a possibility not to be rewarded by the profit of a bonus game since the value of the bonus pool does not reaches a predetermined threshold value.
- If such circumstances occur, a player who has spent many coins may feel unpleasant against the game, build up distrust thereto, or lose interest in or a concern on the game.
- The contents of JP-A 2003-117053 and U.S. Pat. No. 5,820,459 are incorporated here in by reference in their entirety.
- The present invention has been made in light of the above-mentioned problems and it is an object of the present invention to provide: a gaming machine capable of preventing a player who has spent many of the game media such as coins from feeling unpleasant against a game, building up a distrust thereto, or losing interest in or a concern on the game; a control device; and a game system.
- In order to solve the above-mentioned problems, the present invention provides the following configuration:
- (1) A gaming machine comprising:
- winning combination determination means for determining a winning combination by a lottery;
- means for generating a first special game state that is a game state advantageous to a player when the determined winning combination is a special winning combination; and
- means for, when the number of games accumulatively counted each time a game is played reaches a set value that is an object of comparison with the number of games, generating a second special game state in which a probability of hitting the special winning combination by the lottery is set relatively high.
- According to the configuration (1), when the number of games reaches a set value that is an object of comparison with the number of games, the second special game state in which a probability of generating the first special game state is set relatively high is generated.
- Hence, even if the first special game state is not generated for a long period leading to the spending of many of the game media, the second special game state is generated as long as the game is played such that the number of games reaches the set value, and in the first special game state generated during the second special game state, a player can surely receive the return for the fact that a game is played until the number of games reaches a set value. As a result, it can be prevented for a player who has spent many of the game media from feeling unpleasant against the game, building up distrust thereto, or losing interest in or a concern on the game.
- The present invention provides the following configuration:
- (2) A gaming machine connected through a communication line to a control device which counts the number of games accumulatively for every gaming machine of plural gaming machines, comprising:
- winning combination determination means for determining a winning combination by a lottery;
- means for generating a first special game state that is a game state advantageous to a player when the determined winning combination is a special winning combination;
- means for transmitting an identification information of a gaming machine to the control device through the communication line each time a game is played;
- means for receiving a command signal transmitted from the control device when the number of games counted accumulatively by the control device based on the identification information of the gaming machine reaches a set value that is an object of comparison with the number of games; and
- means for generating a second special game state in which a probability of hitting the special winning combination by the lottery is set relatively high, based on the command signal.
- According to the configuration (2), when the number of games counted by the control device reaches a set value that is set as an object of comparison with the number of games, the second special game state in which a probability of generating the first special game state is set relatively high is generated.
- Hence, even if the first special game state is not generated for a long period leading to the spending of many of the game media, the second special game state is necessarily generated as long as the game is played such that the number of games reaches the set value, and in the first special game state generated during the second special game state, a player can surely receive the return for the fact that a game is played until the number of games reaches a set value. Therefore, it can be prevented for a player who has spent many of the game media from feeling unpleasant against the game, building up distrust thereto, or losing interest in or a concern on the game.
- The present invention provides the following configuration:
- (3) A gaming machine comprising:
- winning combination determination means for determining a winning combination by a lottery;
- means for generating a first special game state that is a game state advantageous to a player when the determined winning combination is a special winning combination;
- means for counting accumulatively the number of games each time a game is played;
- means for determining whether or not the number of games has reached a set value that is set as an object of comparison with-the number of games; and
- means for generating a second special game state in which a probability of hitting the special winning combination by the lottery is set relatively high when the number of games is determined to have reached the set value.
- According to the configuration (3), when the number of games reaches a set value that is an object of comparison with the number of games, the second special game state in which a probability of generating the first special game state is set relatively high is generated.
- Hence, even if the first special game state is not generated for a long period leading to the spending of many of the game media, the second special game state is generated as long as the game is played such that the number of games reaches the set value, and in the first special game state generated during the second special game state, a player can surely receive the return for the fact that a game is played until the number of games reaches a set value. As a result, it can be prevented for a player who has spent many of the game media from feeling unpleasant against the game, building up distrust thereto, or losing interest in or a concern on the game.
- The present invention provides the following configuration:
- (4) The gaming machine according to any of the configurations (1) to (3), further comprising:
- means for finishing the second special game state when the player hits the special winning combination by the lottery during generation of the second special game state.

A player can make theticket 39 with a bar code to be read by a second gaming machine and play a game in the second gaming machine, or exchange in a predetermined place (for example, at a cashier in the casino) of a recreation facility theticket 39 with a bar code to notes. - The
card reader 36 is used for reading data from a smart card and writing data onto a smart card. The smart card is a card to be carried by a player, and for example, data to identify a player and data concerning a history of a game played by a player are stored thereon. Data corresponding to a coin, a note or a credit may also be stored on the smart card. As an alternative of a smart card, a magnetic stripe card may be adopted. The data display 37 is a fluorescent display and the like, and it is used, for example, to display data read by thecard reader 36 and data inputted by a player from thekeypad 38. Thekeypad 30 38 is used for inputting a command or data to issue a ticket and the like. -
FIG. 3 is a schematic view showing the symbol sequence depicted on the outer circumferential surface of each reel. - Twenty two symbols each are depicted on the outer circumferential surface of the
left reel 14L, themiddle reel 14 C and theright reel 14 R. A sequence of the symbols depicted on the outer circumferential surface of each of thereels 14 is different from one another. The sequences of the symbols are combinations of the following symbols: “JACKPOT 7”, “BLUE 7”, “BELL”, “CHERRY”, “STRAWBERRY”, “PLUM”, “ORANGE” and “APPLE”. - When the same three symbols of one of the symbols of “
JACKPOT 7”, “BLUE 7”, “BELL”, “CHERRY”, “STRAWBERRY”, “PLUM” and “ORANGE” are stop displayed on the winning line L, a predetermined number of credits is added to the account of the player as a credit owned by the player (seeFIG. 12 ). As for “CHERRY” and “ORANGE”, even if one or two of one of the symbols are stop displayed, a predetermined number of credits are added to the account of the player as credits owned by the player according to the number of the symbols stop displayed (seeFIG. 12 ). - The symbol sequence “APPLE” is a bonus game trigger (a symbol to transit to a bonus game). When three of the “APPLE” are stop displayed on the winning line L, a game state shifts to a bonus game. The bonus game corresponds to the first special game state. In the present embodiment, a bonus game is a free game (a game in which a predetermined number thereof can be played without inserting coins for BET).
- In the present invention, the first special game state is not particularly limited as far as it is a game state advantageous to the player. A game state that is advantageous to the player is not particularly limited as far as it is more advantageous than an ordinary game state (a game state other than the first special game state or the second special game state) and examples thereof include: a state where more of the game media can be earned than in an ordinary game state, a state where the game media can be earned on a probability higher than in an ordinary game state, a state where the number of the game media spent by a player is less than in an ordinary game state and of the like state. More specifically, examples of the first special game state include a free game, a second game, a mystery bonus and the like.
- The sequence of symbols depicted on each of the
reels 14 are, when thespin button 23 is pressed after the 1-BET button or themaximum BET button 27 is pressed to start a game, scroll displayed by scrolling downwards in thedisplay windows 15 during the rotating of thereels 14, and after a predetermined time elapses, the rotating of thereels 14 comes to a stop, and thus the sequence of symbols are stop displayed in thedisplay windows 15. Various kinds of winning combinations (seeFIG. 12 ) are predetermined based on combinations of symbols and when a combination of symbols corresponding to a winning combination stops on the winning line L, the number of payout coins corresponding to the winning combination is added to credits owned by the player. When a bonus game trigger has been established, a bonus game is generated. - When a return mode flag which will be described later has been set to the state “ON”, a game state shifts to a return mode after the symbols are stop displayed as described above. When a bonus game has been generated, the game state shifts to the return mode after the bonus game is over. The return mode corresponds to the second special game state. In the present embodiment, if a game state shifts to the return mode, the probability of the generating of the bonus game becomes relatively high (see
FIG. 14 ). -

The lottery program is a program for determining symbols (code Nos. corresponding to the symbols) on each of thereels 14 which are to be stop displayed on the winning line L. The lottery program contains one or more of symbol weighting determination data, each corresponding to respective plural kinds of payout rates (for example, 80%, 84% and 88%). The symbol weighting determination data is data showing a correspondence relationship between a code No. (seeFIG. 3 ) of each symbol and one or plural random number values from a predetermined numerical value range (0 to 255), for each of the threereels 14. A payout rate is determined based on data for setting a payout rate outputted from theGAL 54, and the lottery is executed based on symbol weighting determination data corresponding to the payout rate. - The
card slot 53S is configured so that thememory card 53 can be inserted therein or drawn out therefrom, and connected to amotherboard 40 through IDE bus. Therefore, a kind or contents of a game played in thegaming machine 10 can be changed by drawing out thememory card 53 from thecard slot 53S, writing a different game program and game system program thereon, and inserting thememory card 53 into thecard slot 53S thereafter. Moreover, a kind or contents of a game played in thegaming machine 10 can also be changed by changing amemory card 53 on which a game program and a game system program are stored to adifferent memory card 53 on which a different game program and game system program are stored. The game program includes a program related to progress in a game; a program for generating the first special game state; and a program for generating the second special game state. The game program further includes: image data and sound data outputted while a game is played and image data and sound data used as notification data. -
GAL 54 is one kind of PLD having an OR fixed array structure.GAL 54 is equipped with a plurality of an input port and an output port and when a predetermined data is inputted to the input port, data corresponding to the input data is outputted from the output port. The data outputted from the output port is the above-mentioned data for setting a payout rate. - The
IC socket 54S is configured such thatGAL 54 can be mounted thereto or demounted therefrom, and connected to themotherboard 40 through PCI bus. Therefore, data for setting a payout rate outputted fromGAL 54 can be changed by drawing outGAL 54 from theIC socket 54S, rewriting a program stored onGAL 54, mountingGAL 54 is to theIC socket 54S thereafter. Moreover, data for setting a payout rate can also be changed by changingGAL 54 to adifferent GAL 54. -

RAM 43 is provided with a storage region for a return mode flag. The return mode flag is a flag to be referred to when a game state is to be selected whether or not it should be shifted to a return mode corresponding to the second special game state. The storage region of the return mode flag is constituted of a storage region with, for example, a predetermined number of bits and the return mode flag is turned “ON” or “OFF” according to storage contents in the storage region. If the return mode flag is set to the state “ON”, the game state thereafter shifts to the return mode without fail. Furthermore, when a bonus game is executed in the return mode, the return mode flag is turned “OFF”.RAM 43 further stores data on the number of credits, the number of coin-in or coin-out for one game, and the like. - The
communication interface 44 is used to communicate with thecontrol device 200 through thecommunication line 101. Themain CPU 41 transmits the number of coin-in and the number of coin-out together with the gaming machine identification number of thegaming machine 10 to thecontrol device 200 each time a game is played. The number of games, an accumulative number of coin-in and an accumulative number of coin-out is made to be associated with each gaming machine identification number, and stored in thecontrol device 200. In thecontrol device 200, a set value that is an object of comparison with the number of games is preliminary determined with respect to each gaming machine identification number, and when the number of games of onegaming machine 10 reaches a set value determined for thatgaming machine 10, a return command signal is transmitted from thecontrol device 200. When themain CPU 41 receives the return command signal through thecommunication interface 44, there turn mode flag is set to the state “ON”. - Both a body PCB (Printed Circuit Board) 60 and a
door PCB 80 which will be described later are connected to themotherboard 40 by USB. Apower supply unit 45 is also connected to themotherboard 40. When electric power is supplied from thepower supply unit 45 to themotherboard 40, not only is themain CPU 41 of themotherboard 40 activated, butCPU 51 is also activated from electric power supplied through the PCI bus to thegaming board 50. - Equipment and devices which generate input signals to be inputted to the

Thelamp 30 is lit up in a predetermined pattern based on a control signal outputted from themain CPU 41. - The
sub CPU 61 controls the rotation and stopping of the reels 14 (14L, 14C and 14R). A motor driving circuit 62 equipped with FPGA (Field Programmable Gate array) 63 and adriver 64 is connected to thesub CPU 61.FPGA 63 is an electronic circuit such as LSI capable of programming and works as a control circuit of a stepping motor 70. Thedriver 64 works as an amplifier circuit of a pulse to be inputted to the stepping motor 70. The stepping motors 70 (70L, 70C and 70R) which rotate each of thereels 14, are connected to the motor driving circuit 62. The stepping motor 70 is a 1-2 phase excitation type stepping motor. - In the present invention, an exciting type of the stepping motor is not particularly limited, and for example, a motor of a 2 or 1 phase excitation type can be adopted. A DC motor may be adopted instead of a stepping motor. When a DC motor is adopted, a deviation counter, a D/A converter and a servo amplifier are sequentially connected to the
sub CPU 61 in this order and the DC motor is connected to the servo amplifier. A rotational position of the DC motor is detected by a rotary encoder and a current rotational position of the DC motor is supplied as data from the rotary encoder to the deviation counter. - An
index detecting circuit 65 and a positionchange detecting circuit 71 are connected to thesub CPU 61. Theindex detecting circuit 65 is used for detecting positions (indexes described later) of the rotatingreels 14 and can also detect an out-of-order state of thereels 14. As for the control of the rotating and stopping of thereels 14, detailed description will be given later by making reference to the figures. - The position
change detecting circuit 71 detects a change of stoppage positions of thereels 14 after the stopping of the rotating of the-reels 14. The positionchange detecting circuit 71 detects the change of stoppage positions of thereels 14, for example, in a case where the stoppage position is changed by force by a player as if the combination of symbols was in a wining state, despite the fact that the combination of symbols is not actually in a wining state, and of the like cases. The positionchange detecting circuit 71 is configured to be capable of detecting the change of stoppage position of thereel 14 by, for example, detecting fins (not shown in the figure) attached with a predetermined space on the inner side of thereel 14. - The
hopper 66 is installed in thecabinet 11 and pays out a predetermined number of coins from acoin payout exit 19 to acoin tray 18 based on a control signal outputted from themain CPU 41. Acoin detecting section 67 is installed inside thecoin payout exit 19 and when detecting that a predetermined number of coins has been paid out from thecoin payout exit 19, outputs an input signal to themain CPU 41. - The
graphic board 68 controls, based on a control signal outputted from themain CPU 41, image displays on the upperimage display panel 33 and the lowerimage display panel 16 as an output device. The number of credits stored inRAM 43 is displayed on the number-of-credits display section 31 of the lowerimage display panel 16.

Moreover, a game history of agaming machine 10 is stored in thehard disc drive 205, by being associated with the gaming machine identification number of each of thegaming machines 10. -
FIG. 6 is a figure schematically showing an example of correspondence table between a gaming machine identification number and a game history. - Each of the gaming machine identification numbers correspond to a game history based on the number of games, an accumulative number of coin-in, an accumulative number of coin-out, a payment balance in terms of the coins and a return rate of coin-out.
- A set value that is an object of comparison with the number of games is determined for each of the gaming machine identification numbers. In the present embodiment, description will be given of a case in which “600” is determined as a set value.
- In the present invention, the values or number of the set values is not particularly limited, and may be set according to circumstances. Moreover, the set value does not need to be set individually for each of the
gaming machines 10, but assigned toplural gaming machines 10 collectively. - When
CPU 201 receives the number of coin-in, the number of coin-out and the gaming machine identification number from thegaming machine 10 through thecommunication interface 204, a game history corresponding to the gaming machine identification number is updated. More specifically, 1 is added to the number of games, the number of coins inserted is added to the accumulative number of coin-in and the number of coins paid out is added to the accumulative number of coin-out. Furthermore, a payment balance in terms of the coins and a return rate are calculated based on the accumulative number of coin-in and the accumulative number of coin-out. WhenCPU 201 determines that the number of games updated has reached a set value, it sends a return command signal to thegaming machine 10. - Next, description will be given of a processing performed in the
gaming machine 10. -
FIG. 7 is a flowchart showing a procedure in an authentication reading processing for a game program and a game system program executed by a motherboard and a gaming board shown inFIG. 4 . Note that thememory card 53 is inserted into thecard slot 53S on thegaming board 50 andGAL 54 is mounted to theIC socket 54S. - When a power supply switch is turned on in the
power supply unit 45, themotherboard 40 and thegaming board 50 are activated (steps S1-1 and S2-1). When themotherboard 40 and the gaming.board 50 are activated, separate processing are performed at the same time. That is, in thegaming board 50,CPU 51 reads a preliminary authentication program stored in theboot ROM 52 and performs the preliminary authentication which in advance, prior to capturing the authentication program into themotherboard 40, confirms or certificates that the program is not altered according to the read preliminary authentication program (step S2-2). On the other hand, in themotherboard 40, themain CPU 41 executes BIOS stored inROM 42 to expand onRAM 43 compressed data incorporated in BIOS (step S1-2). Then, themain CPU 41 executes BIOS expanded onRAM 43 to perform diagnosis on and initialization of various kinds of the peripheral devices (step S1-3). - Then, since
ROM 55 on thegaming board 50 is connected to themain CPU 41 through PCI bus, themain CPU 41 not only performs reading of the authentication program stored inROM 55, but also stores the read authentication program into RAM 43 (step S1-4) On this occasion, themain CPU 41 takes a checksum according to ADDSUM method (a standard check function) with the help of the function of a standard BIOS of BIOS, and by performing a confirmation processing for whether or not storage is conducted without error, stores the authentication program intoRAM 43. - Then, after confirming what is connected to the IDE bus, the
main CPU 41 accesses thememory card 53 inserted into thecard slot 53S through the IDE bus, and conducts reading of the game program and the game system program from thememory card 53. In this case, themain CPU 41 reads 4 bites at a time of data constituting the game program and the game system program. Next, themain CPU 41 authenticates by confirming and certifying according to the authentication program stored inRAM 43, that the read game program and game system program has not been altered (step S1-5). When the authentication processing is normally completed, themain CPU 41 writes and stores inRAM 43 the game program and the game system program that have been an object of authentication (have been authenticated) (steps S1 to S6). Then,main CPU 41 accesses through the PCI bus toGAL 54 mounted to theIC socket 54S, reads data for setting a payout rate fromGAL 54 and writes and stores the data in RAM 43 (step S1-7). Then, themain CPU 41 not only reads through the PCI bus country identification information stored inROM 55 on thegaming board 50, but also stores the read country identification information into RAM 43 (step S1-8). - After the processing is over, the
main CPU 41 sequentially reads and executes the game program and the game system program to such that a game is progressed. - After the processing shown in
FIG. 7 is over, themain CPU 41 performs a game mode selection processing. -
FIG. 8 is a flowchart showing a subroutine of a game mode selection processing. - The
main CPU 41 conducts a processing for adding credits stored inRAM 43 as an interrupt processing when it receives a detection signal outputted from thecoin counter 21C in a case where thecoin counter 21C detects a coin inserted into thecoin receiving slot 21 while executing the subroutine. -
FIGS. 9A and 9B are figures showing an image displayed on the lower image display panel when a game mode selection processing is executed. - To begin with, the
main CPU 41 conducts a processing to display on the lower image display panel 16an image for requesting to the player selection of a game mode (step S3). In this processing, themain CPU 41 transmits a depiction command for the game mode selection image to thegraphic board 68. On the graphic board, VDP extracts image data fromRAM 43 and expands the data on the video RAM to produce image data for one frame and to output the image data to the lower image display panel. 16, based on the depiction command. As a result, for example, an image as shown inFIG. 9A is displayed on the lowerside display panel 16. -
FIG. 9A is a figure showing an example of game mode selection image displayed on the lower image display panel. In the figure, numerical reference 15 (15L, 15C and 15R) indicates display windows. An image showing “Select a mode!!” is displayed in the upper portion of the lowerimage display panel 16. The image is an image for requesting a player to select a game mode. Moreover, images showing “INSURANCE” and “NO INSURANCE” are displayed in the lower portion of the lowerimage display panel 16. The images are images indicating game mode options and the player touches a predetermined site of thetouch panel 69 corresponding to a display region of the image, and is thereby enabled to input a command for selecting a game mode. - The option “INSURANCE” corresponds to the with-insurance mode. A predetermined number of credits (for example, number of credits equivalent to 1 dollar) is required for selecting the with-insurance mode. As an alternative of the number of credits, a note or a coin equivalent to the number of credits may be directly inserted. In a case where the with-insurance mode has been selected, when the number of games reaches a set value (for example, 600) without a bonus game being generated, the return mode flag is set to the state “ON” and a game state shifts to the return mode. In the payout return mode, the probability of the generating of the bonus game becomes relatively high, and the return mode is continued until the bonus game is generated. In other words, in the with-insurance mode, a game can be played in a state where an insurance is carried for compensating all or part of a loss arising in a case where no bonus game has arisen for a long time. On the other hand, an option “NO INSURANCE” corresponds to the without-insurance mode. In a case where the without-insurance mode has been selected, the return mode flag is not set to the state of “ON” and a game state does not shift to the payout return mode even if no bonus game has arisen for a long time after the without-insurance mode is selected.
- After the processing in step S3, the
main CPU 41 determines whether or not the with-insurance mode has been selected (step S4). In a case where it is determined that the with-insurance mode has been selected, the main CPU conducts a processing for subtracting a predetermined number of credit from the number of credits stored in RAM 43 (step S5). Thereafter, the game execution processing in the with-insurance mode is conducted (step S6). - While detailed description of the above-mentioned processing will be given later by making reference to
FIG. 10 , when played in the with-insurance mode, an image showing “INSURED” is displayed in the upper left of the lowerimage display panel 16, as shown inFIG. 9B . The image is an image showing that a game mode is in the with-insurance mode. - On the other hand, in the case where, in step S4, it is determined that the without-insurance mode has been selected, the
main CPU 41 conducts the game execution processing in the without-insurance mode (step S7). Since this processing is a processing almost the same as the game execution processing in the with-insurance mode (seeFIG. 10 ) except that neither a processing related to transition to the return mode nor a processing related to counting of the number of games is conducted, description thereof is omitted here. When the processing in step S6 or S7 has been executed, the process is returned to step S3 thereafter. -
FIG. 10 is a flowchart showing a subroutine of a game execution processing in the with-insurance mode that is called and executed in step S6 of the subroutine shown inFIG. 8 . - In the game execution processing, the
main CPU 41 at first determines whether or not a coin is BET (step S10). In the processing, themain CPU 41 determines whether or not an input signal outputted from the 1-BET switch 26S or themaximum BET switch 27S has been received when the 1-BET button 26 or themaximum BET button 27 is operated, respectively. If it is determined that a coin has not been BET, the process returns to step S10. - On the other hand, if it is determined in step S10 that a coin is BET, the
main CPU 41 conducts a processing for subtracting the number of credits stored inRAM 43 according to the number of BET coins (step S1). In a case where the number of BET coins is more than the number of credits stored inRAM 43, the process returns to step S10 without conducting subtraction on the number of credits stored inRAM 43. In a case where the number of BET coins exceeds the upper limit (50 coins in the present embodiment) up to which a BET is possible in one game, the process advances to step S12 without conducting a processing for subtracting the number of BET coins from the number of credits stored inRAM 43. - Then, the
main CPU 41 determines whether or not thespin button 23 has been turned ON (step S12). In the processing, the main CPU 41 d determines, when thespin button 23 is pressed, whether or not an input signal outputted from thespin switch 23S has been received. - If it is determined that the
spin button 23 has not been turned ON, the process returns to step S10. Note that in a case where the spin button has not been turned ON (for example, in a case where a command of terminating a game has been inputted without turning ON the spin button), themain CPU 41 cancels a result of the subtracting processing in step S11. - In the present embodiment, description will be given of a case in which: after a coin is BET (step S10), a processing for conducting subtraction on the number of credits (step S11) is conducted prior to the determination on whether or not the spin button has been turned ON (step S12). However, the present invention is not limited to this example. For example, a processing for subtraction on the number of credits (step S11) may be conducted after a coin is BET (step S10), determined whether or not the
spin button 23 has been turned ON (step S12), and when determined that thespin button 23 has been turned ON (YES in step S12). - Meanwhile, in step S12 of
FIG. 10 , if it is determined that thespin button 23 has been turned ON therein, themain CPU 41 conducts a lottery processing (step S13). In the lottery processing, the main CPU 41 (processing device) executes a lottery program stored in RAM 43 (storage device) to thereby determine a code No. of the stoppedreels 14. Thus, a combination of symbols stop displayed is determined. Detailed description of the processing will be given later by making reference toFIGS. 11 and 12 . When the processing in step S13 is executed, themain CPU 41 works as winning combination determination means for determining a winning combination by a lottery. In the present embodiment, description will be given of a case where a combination of symbols stop displayed is determined, and one winning combination of plural winning combinations is determined thereafter. However, in the present invention, one winning combination selected from plural winning combinations may at first be determined by a lottery, and the combination of symbols to be stop displayed may be determined thereafter, based on the determined winning combination. - Then, the
main CPU 41 conducts a reel rotating control processing (step S14). The processing is a processing which, after all of thereels 14 starts to rotate, stops the rotating of each of thereels 14 such that a combination of symbol sequences corresponding to the winning combination determined in step S13 is stop displayed on the winning line L. Detailed description of the processing will be given later by making reference to FIGS. 13 to 15. - Then, the
main CPU 41 determines whether or not a bonus game trigger has been established, that is whether or not “APPLE” is stop displayed in the display window 15 (step S15). If it is determined that the bonus game trigger has been established, the main CPU 41 (processing device) reads a program for conducting a bonus game from RAM 43 (storage device) to execute a bonus game processing (step S16). Here, the first special game state is generated. Detailed description of the bonus game processing will be given later by making reference toFIG. 16 . When the processing in step S16 is executed, themain CPU 41 functions as means for generating the first special game state. - On the other hand, if it is determined that the bonus game trigger has not been established, the
main CPU 41 determines whether or not a winning combination has been established (step S17). If it is determined that a winning combination has been established, themain CPU 41 conducts payout of a coin corresponding to the number of coin-in and the winning combination (step S18). - In a case where coins are reserved, the
main CPU 41 conducts a processing to add the coins to the number of credits stored inRAM 43. On the other hand, in a case where payout of a coin is conducted, themain CPU 41 transmits a control signal to thehopper 66 and conducts payout of a predetermined number of coins. In that situation, thecoin detecting section 67 counts the number of coins paid out from thehopper 66 and when the number of counts reaches a designated number, transmits a payout completion signal to themain CPU 41. Thus, themain CPU 41 stops the driving of thehopper 66 to terminate the coin payout processing. - When the processing in step S16 or S18 is executed, or when it is determined that no winning combination has been established (that a winning combination has failed to be established) in step S17, the
main CPU 41 determines whether or not the return mode flag stored inRAM 43 is set to the state “ON” (step S19). If it is determined that the return mode flag has been set to the state “ON”, the main CPU 41 (processing device) reads from RAM 43 (storage device) a program for shifting a game state to the return mode, executes the return mode processing, to thus shift a game state to the return mode (step S20). Here, the second special game state has been generated. Detailed description will be given of the payout return mode processing later usingFIG. 17 . Themain CPU 41, when executing the processing in step S20, functions as means for generating the second special game state. - If the processing in step S20 has been executed, or if it is determined that the return mode flag has not been set to the state “ON” in step S19, the
main CPU 41 determines whether or not the bonus game (step S16) has been executed or whether or not a game state has shifted to the return mode (step S20) (step S21). - If it is determined that a bonus game has not been executed, or that a game state has not shifted to the payout return mode, the
main CPU 41 executes a counting processing (step S22). - The counting processing is a processing conducted between the
gaming machine 10 and thecontrol device 200. The number of coin-in and the number of coin-out for one game together with the gaming machine identification number are transmitted to thecontrol device 200. In thecontrol device 200, the number of games, an accumulative number of coin-in, an accumulative number of coin-out and the like are updated with respect to each gaming machine identification number. - When the number of games reaches a set value, a return command signal is transmitted to the
gaming machine 10 from thecontrol device 200. Themain CPU 41, when receiving the return command signal, sets the return mode flag to the state “ON”. Detailed description of the counting processing will be given later by making reference toFIG. 19 . After the processing in step S22 is executed, themain CPU 41 returns the process to the processing in step S10 and subsequently executes a game in the with-insurance mode. - On the other hand, when it is determined that a bonus game has been executed or a game state has shifted to the payout return mode, the present subroutine is completed and the process returns to the processing shown in
FIG. 8 . As a result, a player can once again select whether a game is to be played by the with-insurance mode or the without-insurance mode. -
FIG. 11 is a flowchart showing a subroutine of a lottery processing called and executed in step S13 of the subroutine shown inFIG. 10 . The processing is a processing conducted by executing a lottery program stored inRAM 43 with themain CPU 41. Themain CPU 41 executes a random number generating program included in the lottery program, and a random number value from the numerical value range of 0 to 255 is selected thereby such that each of the selected random number values correspond to each of the three reels 14 (step S31). In the present embodiment, description will be given of a case where random numbers are generated on a program (a case where so-called software random numbers are used). In the present invention, however, a random number generator may be used, and random numbers may be extracted therefrom (so-called hardware random numbers may be used). - After the random number values are selected, the main CPU 41 (processing device) refers to symbol weighting determination data corresponding to payout rate setting data which is outputted from
GAL 54 and stored inRAM 43, and determines, based on the selected three random number values, code Nos. (seeFIG. 3 ) for each of the reels 14 (step S32). The code Nos. of thereels 14 correspond to code Nos. of the symbols stop displayed on the winning line L. Themain CPU 41 determines code Nos. of thereels 14 to thereby determine a winning combination. For example, in a case where code Nos. of thereels 14 are determined “00”, “00” and “00”, it means that themain CPU 41 determined a winning combination as “JACKPOT”. Based on the code Nos. determined for each of the reels, a reel rotating control processing which will be described later is conducted. On this occasion, themain CPU 41 functions as winning combination determination means. - Here, description of a winning combination in the present embodiment will be given.
-
FIG. 12 is a figure describing a relationship among winning combinations of plural kinds, establishment possibility of each winning combination and the number of coin-out in the present embodiment. The establishment possibilities of each of the winning combinations shown inFIG. 12 are of a case where a payout rate is set to 88% in a game other than a bonus game. The establishment possibilities shown in the figure show possibilities of the establishment of each of the shown winning combinations in such a case that code Nos. of each of thereels 14 are determined based on the selected three random number values by referring to a symbol weighting determination data. In other words, the random number values are not made to correspond to each of the winning combinations. - An establishment possibility of a bonus game trigger is 0.5%. If a player hits the bonus game trigger, three “APPLE” symbols are stop displayed on the winning line L and a bonus game is generated. In the bonus game, executed is a free game of which the number of games is determined by a lottery.
- An establishment possibility of “
JACKPOT 7” is 0.5%. If the winning combination has been established, three “JACKPOT 7” symbols are stop displayed on the winning line L, and 30 coins per one coin-in are paid out. The lower the establishment possibility of the winning combination is, the higher the number of coin-out is set. When a combination of symbols stop displayed is not hitting any of the winning combinations shown inFIG. 12 , this is a failure, and there is no coin-out. -
FIG. 13 is a flowchart showing a reel rotating control processing called and executed in step S15 of the subroutine shown inFIG. 10 . This processing is a processing conducted between themain CPU 41 and thesub CPU 61. - The
main CPU 41 transmits to the sub CPU 61 a start signal that starts the rotating of reels (step S40). Thesub CPU 61 conducts a reel rotating processing when it receives the start signal from the main CPU 41 (step S51). In the processing, thesub CPU 61 supplies a pulse to the motor driving circuit 62. The pulse outputted from thesub CPU 61 is amplified by thedriver 64 and supplied to each of the stepping motors 70 (70L, 70C and 70R). As a result, the stepping motors 70 rotate, there by making the reels 14 (14L, 14C and 14R) to rotate. A stepping motor 70 is a 1-2 phase excitation type stepping motor which has a step angle of 0.9 degree and requires the number of steps of 400 for one rotation. Hence, if 400 pulses are supplied to the stepping motor 70, thereels 14 rotate once. - When the
reels 14 start to rotate, thesub CPU 61 supplies to the motor driving circuit 62 pulses at a lower frequency, and the pulse frequency is gradually raised. A rotational speed of thereels 14 is thereby increased. When a predetermined time elapses, the pulse frequency is controlled to be constant. As a result, thereels 14 rotate at a constant speed. - Here, description of a rotational operation of the
reels 14 will be given, by usingFIG. 14 . -
FIGS. 14A to 14D are side views for describing a rotating operation of areel 14. - As shown in
FIG. 14A , asemicircular metal plate 14 a is attached to the side surface of areel 14. Themetal plate 14 a rotates together with thereel 14. Twenty two symbols (seeFIG. 3 ) are depicted on the circumferential surface of thereel 14. Three symbols of the twenty two symbols depicted on the circumferential surface of thereel 14 can be visually recognizable through thedisplay window 15 formed in front of thereel 14. The arrow mark of a heavy line in the figure indicates a rotating direction of thereel 14. Aproximity sensor 65 a is provided on the side of thereel 14. Theproximity sensor 65 a is used to detect themetal plate 14 a. Theproximity sensor 65 a does not rotate nor move even if thereel 14 rotates. -
FIG. 14A shows a position of themeal plate 14 a when themetal plate 14 a starts being detected by theproximity sensor 65 a (hereinafter also referred to as a position A). If thereel 14 rotates when themetal plate 14 a is at the position A, themetal plate 14 a moves to a position shown inFIG. 14B .FIG. 14B shows a position of themetal plate 14 a when themetal plate 14 a is being detected by theproximity sensor 65 a (hereinafter also referred to as a position B). If thereel 14 rotates when themetal plate 14 a is at the position B, themetal plate 14 a moves to a position shown inFIG. 14C .FIG. 14C shows a position of themetal plate 14 a when themetal plate 14 a will no longer be detected by theproximity sensor 65 a (hereinafter also referred to as a position C). - If the
reel 14 rotates when themetal plate 14 a is at the position C, themetal plate 14 a moves to a position shown inFIG. 14D .FIG. 14D shows a position of themetal plate 14 a when themetal plate 14 a is not detected by theproximity sensor 65 a (hereinafter also referred to as a position D). If thereel 14 further rotates, a position of themetal plate 14 a returns to the position A. As described above, together with the rotating of thereel 14, themetal plate 14 a changes its position in the order from the position A, to the position B, to the position C, to the position D, to the position A and so forth. - The
proximity sensor 65 a constitutes an index detecting circuit 65 (seeFIG. 3 ). When it is referred to as “High” at a state where theproximity sensor 65 a detects themetal plate 14 a, and as “Low” at a state where theproximity sensor 65 a does not detect themetal plate 14 a, a state of theindex detecting circuit 65 is “High” during the period when themetal plate 14 a moves from the position A to the position B and to the position C, and a state of theindex detecting circuit 65 is “Low” during the period when themetal plate 14 a moves from the position C to the position D and to the position A. Thesub CPU 61 assigns a rise from “Low” to “High” as an index (origin) 1 and a fall from “High” to “Low” as an index (origin) 2 to thereby recognize the rotating position of thereel 14. - The
main CPU 40, after transmitting in step 40 a start signal to thesub CPU 61, executes representation to be executed while the reels are rotating (step S41). The process is a processing which conducts display of an image on the lowerimage display panel 16 and output of a sound from thespeaker 29 over a period (for example, 3 seconds) determined according to a result and the like of the lottery processing (step S13 inFIG. 10 ). - Then, the
main CPU 40 determines whether or not it is the timing at which a command is to be issued so as to stop the rotating of the reel 14 (step S42). - The timing at which a command is issued so as to stop rotation of a
reel 14 is a timing before the time when the representation to be executed while the reels are rotating is terminated, which is an interval having the minimum time necessary for stopping the rotating of thereel 14. Note that the minimum time necessary for stopping the rotating of thereel 14 is determined in advance. - If it is determined in step S42 that it is not the timing at which the command to stop the rotating of the
reel 14 is to be issued, the process returns to the processing in step S42 and the representation to be executed while the reels are rotating continues to be conducted. On the other hand, if it is determined in step S42 that it is the timing at which the command to stop the rotating of thereel 14 is to be issued, themain CPU 41 transmits to the sub CPU 61 a code No. of the reel which is stored in RAM 43 (step S43). When thesub CPU 61 receives a code No. of the reel from themain CPU 41, the code No. is converted to a stopping position of the reel (the number of steps) from an index, based on a correspondence table between the number or steps and the code Nos. stored in ROM (not shown in the figure) included in the sub CPU 61 (step S52). -
FIG. 15 is a schematic diagram showing a correspondence table between the number of steps and the code No. Each of the code Nos. are related to an index and the number of steps. - Each code No. corresponds to the symbols depicted on the circumferential surfaces of the reels 14 (see
FIG. 3 ) and symbols of code Nos. “00” to “10” correspond to theindex 1. Moreover, symbols of code Nos. “11” to “21” correspond to theindex 2. - The number of steps in the correspondence table shown in
FIG. 15 is the number of steps with theindex 1 as a reference. For example, if a code No. is “08”, a stopping position of the reel is at 145 steps from theindex 1. If a code No. is “12”, a stopping position of the reel is at 218 steps from theindex 1. - Then, the
sub CPU 61 executes a reel stopping processing (step S53). In the processing, thesub CPU 61 detects a rise in theindex detecting circuit 65 from “Low” to “High” (the index 1) on each of thereels 14, and supplies to themotor driving circuit 65 pulses corresponding to the number of steps which were converted in step S52 from a code No. at a timing at which theindex 1 is detected, and supply of pulses is ceased there after. - For example, when, in step S52, the stopping positions of the reels are determined to be 145 steps from the
index 1, thesub CPU 61supplies 145 pulses to themotor driving circuit 65 at a timing at which theindex 1 is detected, and the supply of pulses is terminated thereafter. Furthermore, when, in step S52, the stopping positions of the reels are determined to be 218 steps from theindex 1, thesub CPU 61supplies 218 pulses to themotor driving circuit 65 at a timing at which theindex 1 is detected. As a result, thereels 14 stop at the code No. determined instep 32 ofFIG. 11 and the combination of symbols corresponding to the winning combination determined in step S32 ofFIG. 11 is stop displayed on the winning line L. On the other hand, themain CPU 41 terminates the representation to be executed while the reels are rotating. After the processing in steps S44 and S53 are over, the present reel rotating control processing is completed. - Moreover, when an index corresponding to the code No. transmitted in step S43 is different from an index detected by the
index detecting circuit 65 when the rotating of thereels 14 stop, this means that an out-of-order state occurred on thereels 14; therefore, themain CPU 41 conducts a processing for displaying an error message on the lowerimage display panel 16 to temporarily stop a game. - For example, in a case where, even though a processing for stopping the
reel 14L was executed at the code No. 12 corresponding to theindex 2, theindex 1 is detected by theindex detecting circuit 65 when the rotating of thereel 14L stops, the game is temporarily stopped. -
FIG. 16 is a flowchart showing a subroutine of a bonus game processing called and executed in step S16 of the subroutine shown inFIG. 10 . In the bonus game processing, firstly, themain CPU 41 determines a number T of bonus games from 10 to 25 games, based on a random number value obtained by executing a random number generation program included in a lottery program stored in RAM 43 (step S60). Themain CPU 41 stores as data intoRAM 43 the number of games of the determined bonus games. - Next, the
main CPU 41 conducts a lottery processing (step S61) and a reel rotating control processing (step S63). The processing in step S61 is a processing almost the same as the processing described usingFIG. 11 . The processing in step S63 is a processing almost the same as the processing described usingFIG. 13 . Since descriptions of these processing have already been given, descriptions thereof are omitted herein. - Then, the
main CPU 41 determines whether or not a bonus game trigger has been established, that is, whether or not three “APPLE” are stop displayed in the display windows 15 (step S64). If it is determined that the bonus game trigger has been established, the number t of additional games of the bonus game is determined in a lottery (step S65) and the determined number t of additional games is added to the number T of games of the bonus game (step S66). Thus, when a bonus game is hit during the bonus game, a remaining number of bonus games increases. More specifically, for example, in a case where a game state shifts to 20 bonus games for the first time, and hits 17 bonus games upon conducting 12 of the bonus games, another 25 bonus games (20 bonus games−12 bonus games+17 bonus games) are to be conducted. - If a bonus game trigger has not been established, the
main CPU 41 determines whether or not a winning combination has been established (step S67). If it is determined that the winning combination has been established, themain CPU 41 conducts payout of coins corresponding to the number of coin-in and the winning combination (step S68). Since the processing is similar to the processing in step S18 and description thereof has already been given, the description of the present processing is omitted herein. - In a case where the processing in step S66 or S68 has been executed, or if it is determined in step S67 that any winning combination has not been established (if it is determined that a failure has occurred), the
main CPU 41 reads the number T of bonus games stored inRAM 43, and one bonus game is subtracted from the read number T of bonus games. The number T of bonus games after the subtraction is again stored into RAM 43 (step S69). - Then, the
main CPU 41 determines whether or not the number T of bonus games reaches the number of games determined in step S60 (step S70). More specifically, it is determined whether or not the number T of games stored inRAM 43 has become 0, and if the number T of games is not 0, that is, if it is determined that the number of bonus games played does not reach the number of games which were determined in step S60, the process returns to step S61 and the above-mentioned processing is repeated. On the other hand, if the number T of games is 0, that is, if it is determined that the number T of games has reached the number of games which were determined in step S60, a number-of-games reset signal is transmitted to the control device 200 (step S71), and the present subroutine is completed thereafter. The number-of-games reset signal includes the gaming machine identification information of thegaming machine 10, andCPU 201 of thecontrol device 200, when receiving the number-of-games reset signal, resets to 0 the number of games of which is stored in thehard disc drive 205 by being made to correspond to the gaming machine identification information included in the number-of-games reset signal. -
FIG. 17 is a flowchart showing a subroutine of a return mode processing called and executed in step S20 of the subroutine shown inFIG. 10 . - The processing in steps S76 to S84 are processing almost the same as the processing described using
FIG. 12 . Since descriptions of these processing have already been given, descriptions thereof are omitted herein. - Here, in a lottery processing executed in step S79, each winning combination is established with a establishment possibility showed in
FIG. 18 . -
FIG. 18 is a figure describing a relationship among winning combinations of plural kinds, establishment possibility of each winning combination and the number of coin-out in a lottery processing of a return mode. - As shown in
FIG. 18 , the establishment possibility of the bonus game trigger is set higher than the establishment possibility of the bonus game trigger shown inFIG. 12 . In the present embodiment, a case in which the establishment possibilities of the winning combinations other than the bonus game trigger are the same as inFIG. 12 will be described. However, the establishment possibilities of the winning combinations other than the bonus game trigger may also be set relatively high compared with those ofFIG. 12 . - In a case where the processing in step S82 or S84 has been executed, or if it is determined in step S83 that any winning combination has not been established (if it is determined that a failure has occurred), the
main CPU 41 determines whether or not the bonus game has been executed (step S85). - When it is determined that the bonus game has not been executed, the
main CPU 41 returns the processing to step S76. On the other hand, themain CPU 41 sets the return mode flag to the state “OFF” (step 86). In the processing of step 86, themain CPU 41 functions as means for finishing the second special game state when a player hits a special winning combination by a lottery during generation of the second special game state. Thereafter, the present subroutine is completed. -
FIG. 19 is a flowchart showing a counting processing called and executed in step S22 of the subroutine shown inFIG. 10 . - The processing is a processing conducted between the
main CPU 41 of agaming machine 10 andCPU 201 of thecontrol device 200. Here, a set value “600” is set to each of the plural gaming machines 10 (seeFIG. 6 ). - To begin with, the
main CPU 41 transmits by thecommunication interface 44 the number of coin-in and the number of coin-out stored inRAM 43 together with the gaming machine identification number to thecontrol device 200 through the communication line 101 (step S90). The number of coin-in and the number of coin-out transmitted to thecontrol device 200 from thegaming machine 10 are those of the game concerned. - The processing in step S90 is a processing in which the main CPU 41 (processing device) transmits the identification information of the
gaming machine 10 stored in the main RAM 43 (storage device) to thecontrol device 200 through thecommunication line 101, each time a game is played. When the processing in step S90 is executed, themain CPU 41 functions as means for transmitting the identification information of thegaming machine 10 to thecontrol device 200 through thecommunication line 101. - On the other hand, the
CPU 201 of thecontrol device 200, when receiving from thegaming machine 10 the number of coin-in, the number of coin-out and the gaming machine identification number through thecommunication line 101 by thecommunication interface 204, updates the number of games, the accumulative number of coin-in and the accumulative number of coin-out corresponding to the received gaming machine identification number (step S100), by choosing the data, which are made to correspond to each of the gaming machine identification numbers, of the number of games, the accumulative number of coin-in, the accumulative number of coin-out stored in the hard disc drive 205 (seeFIG. 6 ). - Then,
CPU 201 determined whether or not the number of games after the updating has reached the set value (step S101). If it is determined that the number of games after the updating has not reached the set value, the subroutine is terminated. - On the other hand, if it is determined in step S101 that the number of games after the updating has reached the set value,
CPU 201 transmits a return command signal through thecommunication line 101 by thecommunication interface 204 to thegaming machine 10 in which the number of games has reached the set value (step S103). Thereafter,CPU 201 resets to 0 the number of games stored in thehard disc drive 205 which are made to correspond to the gaming machine-identification number of the gaming machine 10 (step S104). Thereafter, the present processing is terminated. - The
main CPU 41 of thegaming machine 10, when receiving the return command signal transmitted from thecontrol device 200 in step S103, sets the return mode flag to the state “ON” (step S91). The processing in step S91 is a processing for receiving a command signal transmitted from thecontrol device 200 when the number of games accumulatively counted by thecontrol device 200 based on the identification information of thegaming machine 10 reaches a set value that is an object of comparison with the number of games. Instep S91, themain CPU 41 functions as means for receiving a command signal transmitted from the.control device 200. Thereafter, the present processing is terminated. - In the present embodiment, description has been given of a case where a game state shifts to the return mode when the number of games reaches a set value (see
FIG. 19 ). The present invention is, however, not limited to this example. For example, in a case where the number of inserted game media for a game played by the player is at the upper limit value that can be accepted in one game when the number of games reaches the set value, the second special game state may be generated (the game state shifts to the return mode). This is because in such a case, a player can be urged to insert game media up to the upper limit and a facility such as a casino and the like can increase a profit. - Moreover, in a case where the second special game state is generated when the number of inserted game media is at the upper limit value, the second special game state maybe generated not when the number of games reaches the set value, but when the number of inserted game media is at the upper limit value for a game played by a player when the number of games in which insertion of game media is conducted to the upper limit value reaches a set value. This is because, in such a case, it can be prevented from a small number of game media to be inserted in a game, thereby leading to a fact that the second special game state is generated by the spending of only a small number of game media in total.

Therefore, it can be prevented for a player who has spent many of the game media from feeling unpleasant against the game, building up distrust thereto, or losing interest in or a concern on the game.
- The
gaming machine 10 is connected through thecommunication line 101 to thecontrol device 200 and thecontrol device 200 counts payment balance in terms of coins in thegaming machine 10, and determines whether or not the payment balance in terms of coins reaches a set value. Thegaming machine 10 is, however, not necessarily required to be those using a network and may be standalone. - Such a gaming machine 10 includes the main CPU 41 (processing device) and RAM 43 (storage device), wherein the main CPU 41 executes: a processing determining one winning combination selected from plural winning combinations determined in advance by executing a lottery program stored in RAM 43; a processing reading from RAM 43 a program for generating a bonus game (the first special game state) when the determined winning combination is a special winning combination, “bonus game trigger”, and executing the program; a processing accumulatively counting a payment balance in terms of game media each time a game is played; a processing selecting a set value that is an object of comparison with a payment balance in terms of game media, from plural candidate values stepwise determined in advance; a processing determining whether or not a payment balance in terms of game media is equal to or less than a set value; a processing reading from RAM 43 a program for conducting transition to the return mode (the generating of the second special game state) in which a probability of hitting the special winning combination, “bonus game trigger”, by executing the lottery program is set relatively high when it is determined that a payment balance in terms of game media is equal to or less than a set value, and executing the program; and a processing finishing the return mode when a player hits the special winning combination, “bonus game trigger”, by the lottery during generation of the return mode.
- This gaming machine 10 includes: winning combination determination means (for example, the main CPU 41) for determining a winning combination by a lottery; means (for example, the main CPU 41) for generating a bonus game (the first special game state) when the determined winning combination is a special winning combination, “bonus game trigger”; means (for example, the main CPU 41) for accumulatively counting a payment balance in terms of game media, each time a game is played; means (for example, the main CPU 41) for selecting a set value from plural candidate values stepwise determined in advance; means (for example, the main CPU 41) for determining whether or not a payment balance in terms of game media is equal to or less than a set value; means (for example, the main CPU 41) for conducting transition to the return mode (the generating of the second special game state) in which a probability of hitting the special winning combination, “bonus game trigger”, by the lottery program is set relatively high when it is determined that the payment of balance in terms of game media is equal to or less than a set value; and means (for example, the main CPU 41) for finishing the return mode when a player hits the special winning combination, “bonus game trigger”, by the lottery during generation of the return mode.
- In the present embodiment, there has been described the case where the set values of all the
gaming machines 10 are set to “600”. However, in the present invention, thegaming machines 10 may have different set values respectively. For example, the set value may be selected from plural candidate values stepwise determined in advance. - In the present embodiment, there has been described the case where the second special game state is continued until the first special game state is generated. However, in the present invention, the second special game state is not limited to this example as long as it is continued until predetermined conditions are satisfied. If such configuration is employed, examples of the predetermined conditions for finishing the return mode include elapse of a predetermined period, establishment of a predetermined winning combination by a predetermined number of times, and the like.
- In the present invention, the second special game state is not particularly limited as far as it is a game state advantageous to the player. A game state that is advantageous to the player is not particularly limited as far as it is more advantageous than an ordinary game state (a game state other than the first special game state or the second special game state) and examples thereof include: a state where more of the game media can be earned than in an ordinary game state, a state where the game media can be earned on a probability higher than in an ordinary game state, a state where the number of the game media spent by a player is less than in an ordinary game state and of the like state. More specifically, examples of the second special game state include a free game, a second game, a mystery bonus and the like.
- In the present embodiment, description has been given of a case where a game state shifts to the return mode when the return mode flag has been set to the state “ON”, without other conditions being established there after. The present invention is, however, not limited to this example and, for example, a game state may shift to the return mode when a predetermined condition has been met after the return mode flag is set to the state “ON”. In such a case, the predetermined condition for transition to the return mode is not particularly limited, and may include, for example, establishment of a bonus game trigger, stop display of a predetermined combination of symbols, and of the like conditions.
- In the present embodiment, description has been given of a case where a game state shifts to the return mode when the return mode flag is set to the state “ON”, regardless of the combination of symbols stop displayed thereafter. However, the present invention is not limited to this example. For example, a combination of symbols corresponding to the transition to the return mode may be set in advance and a game state may shift to the return mode after the symbols are stop displayed in that winning combination.
- In the present embodiment, description has been given of a case where symbols are stop displayed (step S14 in
FIG. 10 ), a processing is conducted based on the stop displayed combination of symbols (steps S15 to S20 inFIG. 10 ), and the number of games is counted (step S22 inFIG. 10 ) thereafter. In the present invention, however, no specific limitation is placed on a timing at which counting of the number of games is conducted. For example, the timing may be a timing at which BET of a coin is conducted (after step S10 or S11 inFIG. 10 ) or a timing at which the spin button is turned ON (after step S12 inFIG. 10 ). The number of games may be counted at a predetermined timing that is in the period from the time when display of a change in symbol is started, to the time when symbol sequences are stop displayed, and a processing based on the stop displayed combination of symbols has been conducted (for example, a timing at which symbol sequences are stop displayed). Note that a timing at which a payment balance in terms of game media can be the same as described above. - In the present embodiment, description has been given of a
gaming machine 10 in which in a case where a special winning combination, “bonus game trigger”, has been established (step S15 inFIG. 10 ) in the period from the time when the return mode flag is set to the state “ON” (step S22 inFIG. 10 ), to the time when transition to the return mode is conducted (step S20 inFIG. 10 ), transitions to the return mode is further conducted after the bonus game is generated (step S16 inFIG. 10 ). That is, a gaming machine according to the present embodiment generates the first special game state based on the a special winning combination, and further generates the second special game state, in a case where the special winning combination is established in the period from the time when the number of games reaches a set value, to the time when the second special game state is generated. - However, the present invention is not limited to this example. For example, in a case where a special winning combination is established in the period from the time when the number of games reaches a set value, to the time when the second special game state is generated, only the first special game state may be generated. In a case where the above embodiment is adopted, a player can earn a profit in the first special game state or the second special game state without fail when a game is played until the number of games reaches the set value. The above embodiment is one of the embodiments of the present invention. In a case where the above embodiment is adopted for the
gaming machine 10, for example, the following processing has only to be conducted instead of the processing shown inFIG. 10 . -
FIG. 20 is a flowchart showing another example of a subroutine of a game execution processing. In the flowchart shown inFIG. 20 , the same numerical references are assigned to steps which conduct processing similar to those in the flowchart shown inFIG. 10 . - After the processing in steps S10 to S14 are executed, the
main CPU 41 determines whether or not a bonus game trigger has been established (step S15) and if it is determined that the bonus game trigger has been established, a bonus game processing is executed (step S16). Then, it is determined whether or not a return mode flag is set to the state “ON” (step S25) and if the return mode flag is set to “ON”, the return mode flag is set to the state “OFF” (step S26). The processing in step S21 is performed there after and thus the present subroutine is completed. Since the other processing are processing similar to those described inFIG. 10 , descriptions thereof are omitted here. In the subroutine shown inFIG. 20 , after a coins is BET (step S10), in a case where it is determined whether or not thespin button 23 has been turned ON (step S12), and if it is determined that the spin button has been turned ON (YES in step S12), a processing for subtracting the number of credits (step S11) may be conducted, as in the subroutine shown inFIG. 10 . - A more specific description of the processing shown in
FIG. 20 will be given here with a case where a set value is 600. In a case where, in step S22, the number of games reaches 600 and a return mode flag has been established, if a bonus game trigger has been established (step S15) in the 601st game, the bonus game is generated (step S16) but transition to the return mode is not performed (steps S25 and S26). On the other hand, in a case where a bonus game trigger has not been established in the 601st game run, transition to the return mode is conducted (steps S19 and S20). - Hence, in a case where the processing shown in
FIG. 20 is performed, a bonus game is generated or transition to the return mode is performed without fail, when the number of games reaches a set value. - In the present invention, in a case where a special winning combination has been established in the period from the time when the number of games reaches a set value, to the time when the second special game state is generated, only the second special game state may be generated, or alternatively, either the first special game state or the second special game state may be generated depending on a game situation and the like.
- An embodiment similar to the above-mentioned embodiment can also be adopted in a case where the second special game state is generated according to a payment balance in terms of game media. In other words, in a case where a special winning combination has been established in the period from the time when a payment balance in terms of game media is equal to or less than a set value, to the time when the second special game state is generated, only the first special game state may be generated, only the second special game state may be generated, or either the first special game state or the second special game state may be generated depending on a game situation and the like.
- Although the embodiment according to the present invention has been described, the description presents only some of the specific examples, and is not intended to limit the present invention in any way and specific constructions of each means and the like can be properly changed in terms of design. Besides, the effects described in the embodiment of the present invention are only the most preferable effects generated from the present invention and effects to be caused by the present invention is not limited to those described in the embodiment of the present invention.
