Description

  The present invention relates to a gaming machine such as a slot machine, and more particularly to a gaming machine that executes a free game that performs a plurality of free spins.

  2. Description of the Related Art Conventionally, a gaming machine called a slot machine is provided rotatably in a housing and includes a plurality of reels on which a plurality of types of symbols are drawn on an outer peripheral surface thereof. Then, when a specific symbol on the reel is stopped on the effective winning line, the reel is automatically rotated / stopped a predetermined number of times (for example, 10 times) free spin (without newly digesting coins, etc.) There is known a gaming machine that shifts to a free game in which a coin is paid out in accordance with a combination of symbols.

  In such a free game, whether or not to display a combination of symbols in a predetermined winning mode on the effective pay line during free spin is determined according to a lottery result performed for each free spin (for example, , See Patent Document 1). That is, in each gaming machine, each time a free spin is performed, it is determined whether to allow a combination of symbols displayed at the time of stoppage to be in a predetermined winning mode using a random number or the like.

On the other hand, there is known a gaming machine that performs a new free game continuously after the end of the current free game when a specific symbol is again stopped on the effective winning line during a predetermined number of free spins. . Since a state that is very advantageous for the player continues when the free game continues, the player expects that a specific symbol stops on the active winning line before the current free game ends. In particular, the expectation is extremely high in a predetermined number of final free spins.
JP-A-2005-34301

  However, in conventional gaming machines, the combination of symbols displayed on the active winning line during free spins is determined according to the lottery result performed for each free spin, which will lead to the occurrence of a new free game. The player could not figure out whether a particular symbol stopped on the active winning line. For this reason, there is a problem that the player cannot expect to enjoy the free game purely because he / she starts to think about a situation where he / she can not move to a new free game while expecting at the end of a predetermined number of free spins.

  The present invention has been made in view of the circumstances as described above, and an object of the present invention is to provide a gaming machine that can sufficiently enhance the interest of a game during a free game.

  In order to achieve the above object, a gaming machine according to the present invention comprises variable display means for variably displaying a plurality of symbols used in a game, and control means for controlling variable display in the variable display means, The control means collectively performs a lottery performed according to the number of free spins in the free game, and if there is a winning combination that becomes a winning mode including a specific symbol in the result of the batch lottery, the last free spin The variable display of the variable display means is controlled so that the corresponding winning combination is displayed.

  According to this gaming machine, the lottery performed in accordance with the number of free spins during the free game is performed in a lump, and if there is a winning combination that becomes a winning mode including a specific symbol in the result of the batch lottery, Since the winning role is stopped and displayed in a free spin, the expectation for the transition to a new free game and the acquisition of a large amount of game media can be maintained until the last free spin. It is possible to fully enhance the interest of.

  In particular, in the above gaming machine, the control means displays the winning combination in the last free spin when there is a winning combination that includes a specific symbol that triggers the transition to a new free game. It is preferable to control the variable display of the variable display means. In this case, the winning combination that includes a specific symbol that triggers the transition to the new free game at the last free spin will be stopped and displayed, so the expectation for the transition to the new free game will be final. Since it is possible to maintain up to free spins, it is possible to sufficiently enhance the interest of the game during the free game.

  In the above gaming machine, the control means displays the winning combination in the last free spin when there is a winning combination in a winning mode including a specific symbol in which the number of game media acquired is greater than a certain number. Thus, it is preferable to control the variable display of the variable display means. In this case, the winning combination that is a winning mode including a specific symbol in which the number of game media acquired in the last free spin is more than a certain number is stopped and displayed, so expectation for the acquisition of a large amount of coins etc. Since the spin can be maintained, it is possible to sufficiently enhance the interest of the game during the free game.

  According to the gaming machine of the present invention, it is possible to fully enhance the interest of the game during the free game.

  The 3-BET button 13 is a button for starting a game with three bets based on the depression thereof. The 5-BET button 14 is a button for starting a game with 5 bets based on the depression thereof. A coin payout exit 15 is formed at the lower portion of the cabinet 2, and a coin receiving portion 16 that receives coins paid out from the coin payout exit 15 is provided.

  Four reels as variable display means are arranged at positions facing the four variable display portions 22 to 25 formed in the lower liquid crystal display 4. Of the four reels, the leftmost reel as viewed from the front of the slot machine 1 faces the variable display portion 22 formed in the lower liquid crystal display 4, and the central left reel is similarly the variable display portion 23. Opposite to. Further, the reel on the right side of the center similarly faces the variable display portion 24, and the reel on the rightmost side similarly faces the variable display portion 25.

  Various symbols as shown in FIG. 2 used in a normal game are formed on the outer peripheral surface of each reel. FIG. 2 is an example of a symbol that is formed on the outer peripheral surface of each reel and is variably displayed while scrolling on each of the transparent variable display portions 22 to 25 of the lower liquid crystal display 4 during a normal game. FIG.

  In FIG. 2, a symbol row 141 is a symbol row that is variably displayed on the variable display portion 22, and a symbol row 142 is a symbol row that is variably displayed on the variable display portion 23. The symbol row 143 is a symbol row that is variably displayed on the variable display portion 24, and the symbol row 144 is a symbol row that is variably displayed on the variable display portion 25.

  The symbol rows 141, 142, and 143 all have the same symbol arrangement, and these symbol rows are triple BAR91, cherry 92, double BAR93, seven 94, single BAR95, and blank (area where no symbols exist). ) 96 are appropriately combined to form 11 symbols.

  The symbol row 144 is different from these symbol rows in that one trigger symbol 97 is arranged in addition to the symbols included in the symbol rows 141, 142, and 143. The trigger symbol 97 is a symbol for shifting to a bonus game, which will be described later. When the trigger symbol 97 is stopped and displayed on the active pay line L in the variable display section 23, the trigger symbol 97 can shift to the bonus game.

  When forming various symbols on each reel aspect, 11 symbols are printed on a long reel sheet that matches the width and station length of each reel, and the reel sheet is attached to each reel aspect. However, it is of course possible to form the pattern by a method other than this method.

  When the symbol rows 141 to 144 being scrolled on the variable display portions 22 to 25 are stopped and displayed, the four symbols are stopped and displayed on the variable display portions 22 to 25, respectively. In addition, various winning combinations are set in advance based on a plurality of combinations of symbols, and when a combination of symbols corresponding to the winning combination stops on the effective winning line L, coins are coined according to the winning combination. The points paid out from the payout port 15 are the same as those in the conventional slot machine, and the description thereof is omitted here.

  Next, a configuration related to the control system of the slot machine 1 will be described with reference to FIG. FIG. 3 is a block diagram schematically showing a control system of the slot machine.

  In FIG. 3, the control system of the slot machine 1 is basically configured with a microcomputer 100 composed of a CPU 50, ROM 51, and RAM 52 functioning as control means, and the ROM 51 and RAM 52 are connected to the CPU 50. ing. The ROM 51 stores various programs, data tables, and the like for performing processing necessary for controlling the slot machine 1 such as main processing, start acceptance processing, lottery processing, normal game processing, bonus game processing, which will be described later. The RAM 52 is a memory that temporarily stores various data calculated by the CPU 50.

  In the present embodiment, the programs, data, and the like used when controlling the slot machine 1 are not limited to being stored in the ROM 51 or the RAM 52 in advance, and can be changed as appropriate. For example, the same program, data, and the like may be stored in a storage medium such as a compact flash (registered trademark) and downloaded from the storage medium to the ROM 51 or the like.

  The CPU 50 is connected to a clock pulse generation circuit 53 that generates a reference clock pulse and a frequency divider 54, and is also connected to a random number generator 55 that generates a random number and a random number sampling circuit 56. The random numbers sampled through the random number sampling circuit 56 are used for various lotteries such as a winning combination. Further, the CPU 50 has a spin switch 58 attached to the spin button 12, a 1-BET switch 59 attached to the 1-BET button 11, and a 3-BET switch 60 attached to the 3-BET button 13, 5-BET. A 5-BET switch 61 attached to the button 14, a change switch 62 attached to the exchange button 6, a refund (CASHOUT) switch 63 attached to the refund button 7, and a help attached to the help button 8. (HELP) switches 64 are connected to each other. The CPU 50 performs control to execute various operations corresponding to the buttons based on the switch signals output from the switches when the buttons are pressed.

  Four stepping motors 68 that rotate the reels 220 are connected to the CPU 50 via a motor drive circuit 167. When a motor drive signal is output from the CPU 50 to the motor drive circuit 167, each stepping motor 68 is rotationally driven by the motor drive circuit 167. Thereby, each reel 220 is rotated. At this time, after the rotation of each reel 220 is started, the number of drive pulses supplied to each of the stepping motors 68 is calculated, and the calculated value is written in a predetermined area of the RAM 52. Further, a reset pulse is output from each reel 220 for each rotation and is input to the CPU 50. When the reset pulse is input to the CPU 50 in this way, the calculated value written in the RAM 52 is cleared to “0”, and the CPU 50 determines the calculated value corresponding to the rotational position within one rotation range of each reel 220. Based on the symbol table in which the rotational position of each reel 220 stored in the ROM 51 is associated with the symbol formed on the phase of each reel 220, the rotational position of the symbol on each reel 220 is recognized.

  A position change detection circuit 69 is connected to the CPU 50. The position change detection circuit 69 detects a change in the stop position of the reel 220 after the stop control is performed by the motor drive circuit 167 described above. For example, in the position change detection circuit 69, the stop position is changed by the player so as to be a combination of stop symbols that is in a winning mode, even though it is not actually a combination of stop symbols in a winning mode. A change in the stop position of the reel 220 in some cases is detected. The position change detection circuit 69 is configured to detect a change in the stop position of the reel 220 by detecting fins attached to the inner portion of the reel 220 at predetermined intervals, for example.

  The CPU 50 is connected to a coin sensor 65 disposed in the coin insertion unit 9 and a bill sensor 66 disposed in the bill insertion unit 10. The coin sensor 65 detects a coin inserted from the coin insertion unit 9, and the CPU 50 calculates the number of coins inserted based on a coin detection signal output from the coin sensor 65. The bill sensor 66 detects the type and amount of the bill inserted from the bill insertion unit 10, and the CPU 50 calculates the number of coins equivalent to the amount of the bill based on the bill detection signal output from the bill sensor 66.

  A hopper 71 is connected to the CPU 50 via a hopper drive circuit 70. When a driving signal is output from the CPU 50 to the hopper driving circuit 70, the hopper 71 pays out a predetermined number of coins from the coin payout exit 15. Further, a coin detection unit 73 is connected to the CPU 50 via a payout completion signal circuit 72. The coin detection unit 73 is disposed inside the coin payout exit 15. When it is detected that a predetermined number of coins have been paid out from the coin payout exit 15, a coin payout detection signal is output from the coin detection unit 73 to the payout completion signal circuit 72, and the payout completion signal circuit 72 is based on this signal. The payout completion signal is output to the CPU 50.

  An upper liquid crystal display 3 and a lower liquid crystal display 4 are connected to the CPU 50 via a liquid crystal driving circuit 74, and the upper liquid crystal display 3 and the lower liquid crystal display 4 are controlled by the CPU 50. As shown in FIG. 4, the liquid crystal drive circuit 74 includes a program ROM 81, an image ROM 82, an image control CPU 83, a work RAM 84, a VDP (video display processor) 85, a video RAM 86, and the like.

  In FIG. 4, the program ROM 81 stores an image control program related to display on the upper liquid crystal display 3 and the lower liquid crystal display 4 and various selection tables. The image ROM 82 stores, for example, dot data for forming an image on the upper liquid crystal display 3 and the lower liquid crystal display 4. Based on the parameters set by the CPU 50, the image control CPU 83 follows the image control program stored in advance in the program ROM 81 from the dot data stored in advance in the image ROM 82 to the upper liquid crystal display 3 and the lower liquid crystal display 4. Determine the image to be displayed. The work RAM 84 is configured as a temporary storage unit when the image control program is executed by the image control CPU 83. The VDP 85 generates image data corresponding to the display contents determined by the image control CPU 83 and outputs the image data to the upper liquid crystal display 3 and the lower liquid crystal display 4. The video RAM 86 is configured as a temporary storage unit when an image is formed by the VDP 85.

  As shown in FIG. 3, an LED 78 is connected to the CPU 50 via an LED drive circuit 77. A large number of LEDs 78 are arranged on the front surface of the slot machine 1 and are controlled to be turned on by the LED drive circuit 77 based on a drive signal from the CPU 50 when performing various effects. A sound output circuit 79 and a speaker 80 are connected to the CPU 50, and the speaker 80 generates various sound effects when performing various effects based on output signals from the sound output circuit 79.

  The lamp 20 is connected to the CPU 50 via a lamp driving circuit 75. The lamp 20 is disposed on the upper surface of the slot machine 1 (see FIG. 1), and when the exchange button 6 is pressed, the lamp driving circuit 75 controls lighting based on a driving signal from the CPU 50.

  The transparent touch panel 30 is connected to the CPU 50 via the touch panel drive circuit 67. The transparent touch panel 30 is provided on the screen of the lower liquid crystal display 4 and outputs the coordinate position information of the part touched by the player via the touch panel drive circuit 67 so that the CPU 50 can determine where the touch is made. It has become.

  Next, an operation example of the slot machine 1 having the above configuration will be described.

  First, an example of main processing performed in the slot machine 1 will be described with reference to FIG. FIG. 5 is a flowchart of an example of the main process. When starting the main process, the slot machine 1 (more specifically, the CPU 50) first executes a start acceptance process (step (hereinafter abbreviated as “S”) 11). This process is performed based on the operation of the spin button 12, the operation of the 1-BET button 11, the operation of the 3-BET button 13, or the operation of the 5-BET button 14, and the spin switch 58, 1-BET switch 59, 3-BET switch. This is processing for receiving a switch signal output from the 60 or 5-BET switch 61. The game is started when a switch signal output from each switch is received.

  The start acceptance process performed in the slot machine 1 will be described with reference to FIG. FIG. 6 is a flowchart of an example of the start reception process. In S11 of the main process shown in FIG. 5, the CPU 50 first determines whether or not a predetermined time (for example, 15 seconds) has elapsed (S21). Here, when it is determined that the predetermined time has not elapsed (S21, No), the process proceeds to S23 without performing anything, but when it is determined that the predetermined time has elapsed (S21, Yes). In S22, the demonstration effect process is performed on the upper liquid crystal display 3 and the lower liquid crystal display 4, and then the process proceeds to S23. This demonstration effect process is performed according to a predetermined effect pattern.

  In S23, the CPU 50 determines whether or not the operation of the spin button 12, the operation of the 1-BET button 11, the operation of the 3-BET button 13 or the operation of the 5-BET button 14 has been performed. Here, when it is determined that the operation of the 1-BET button 11 or the like is not performed (S23, No), the process returns to S21 and the above-described processing is repeated. On the other hand, if it is determined that the operation of the 1-BET button 11 or the like has been performed (S23, Yes), even during the demonstration effect process, the process returns to the main process shown in FIG. Proceed to

  Next, the lottery process (S12) performed in the slot machine 1 will be described with reference to FIG. FIG. 7 is a flowchart of an example of a lottery process. In S12 of the main process shown in FIG. 5, the CPU 50 first performs a random number extraction process (S31). In this random number extraction process, the CPU 50 samples one random number via the random number sampling circuit 56.

  Following the random number extraction process (S31), the CPU 50 executes a combination determination process (S32). This combination determination process compares the random number extracted in S31 with a lottery table prepared in advance that describes the correspondence between random numbers and combinations (including loses), and determines the combination corresponding to the extracted random number. It is a process to decide. For example, if the random number is any one of 1 to 10, the lottery table is a “bonus game”, and if the random value is any of 11 to 40, the combination “all seven”,... This is a table describing that the role is “losing” in any of 341 to 1024. In addition, the above-mentioned combination “all seven” is a case where all the symbols stopped on the effective winning line L are the symbols “seven”.

  Following the combination determination process (S32), the CPU 50 executes a stop symbol determination process (S33). This stop symbol determination process is a process for determining for each of the variable display units 22 to 25 the symbols to be stopped and displayed on the effective winning line L so that the combination determined in the combination determination process is established. Specifically, the CPU 50 determines the code number of the stop symbol for each reel 220 so that a combination of symbols corresponding to the determined combination is established on the effective pay line L. To decide. After the stop symbol determination process (S33) ends, the process returns to the main process shown in FIG. 5 and proceeds to the normal game process of S13.

  Next, the base game process (S13) performed in the slot machine 1 will be described with reference to FIG. FIG. 8 is a flowchart of an example of the normal game process. In S13 of the main process shown in FIG. 5, the CPU 50 first outputs from the spin switch 58, 1-BET switch 59, 3-BET switch 60 or 5-BET switch 61 received in the start reception process (S11). Based on the switched signal, a rotation process for starting rotation of the four reels 220 in the cabinet 2 is executed (S41). By this rotation processing, the symbols are scrolled on the variable display sections 22 to 25. At this time, since the variable display portions 22 to 25 are in a see-through state, the scroll of each symbol can be visually recognized.

  Next, the CPU 50 rotates the four reels 220 in the cabinet 2 so as to stop the stop symbol determined in the lottery process (S12), more specifically, the stop symbol determination process (S33), on the effective winning line L. A stop control process for stopping is executed (S42). By this stop control process, the scroll of each symbol in the variable display sections 22 to 25 is stopped.

  Next, the CPU 50 temporarily assigns coins corresponding to a predetermined payout to coins to be paid out in accordance with the symbol combination of the winning combination stopped and displayed on each of the variable display units 22 to 25 in the stop control process (S42). Addition processing to be added to is executed (S43). The coins to be paid out are allocated and stored in a certain area of the RAM 52. In this addition process, coins and the like are added according to the combination determined in the combination determination process (S32). In addition, after performing this addition process, CPU50 returns to the main process shown in FIG.

  Returning to FIG. 5, the description of the main process will be continued. After executing the normal game process (S13), the CPU 50 determines whether or not a bonus game is established (S14). This determination is made based on the symbol stopped on the effective pay line L in the stop control process (S42) in the normal game process shown in FIG. 8, or the random number or combination determined in the lottery process (S12).

  When determining that a bonus game is being established (S14, Yes), the CPU 50 executes a bonus game process (S15). In the bonus game process (S15), the slot machine 1 executes a free game that performs free spins a predetermined number of times (10 times in the present embodiment). That is, in the slot machine 1 according to the present embodiment, the bonus game corresponds to a free game in which 10 free spins are permitted.

  When performing a free spin, the player performs the same processing as the normal game without inserting coins or pressing a bet button, that is, without consuming coins or accumulated credits. Therefore, during the bonus game, the player can receive payment of coins or credits without depleting the number of coins or credits, so that the player is very advantageous in terms of coin acquisition or credit acquisition.

  When performing a free spin, the slot machine 1 according to the present embodiment performs a lottery process that has been conventionally performed for each free spin in a batch at the beginning of the bonus game process, and a specific lottery result is specified. When a winning combination that is a winning mode in which symbols are arranged is included, the winning combination is controlled to be stopped and displayed at the last free spin. This enhances the interest of the game during the free game by maintaining the expectation for the transition to a new free game during the free game until the last free spin.

  Hereinafter, bonus game processing performed in the slot machine 1 will be described with reference to FIG. FIG. 9 is a flowchart of an example of the bonus game process. In S15 of the main process shown in FIG. 5, the CPU 50 first performs a batch lottery process (S51). In this batch lottery process, a lottery process for all free spins of a predetermined number of times is performed in a lump, and a winning combination (hereinafter referred to as a “special winning combination”) that becomes a winning mode in which specific symbols are arranged in the result of the batch lottery If it is included, it is a process of determining a stop symbol so that the specific winning combination is stopped and displayed at the last free spin.

  Here, the batch lottery process executed in the bonus game process will be described with reference to FIG. As shown in FIG. 10, when the batch lottery process is started, the CPU 50 first performs a random number extraction process (S61), and subsequently executes a combination determination process (S62). Since these random number extraction processing and combination determination processing are the same as the processing performed in the lottery processing described in FIG. 7, detailed description thereof is omitted. The combination determined in the combination determination process is stored in a predetermined area on the RAM 52.

  When the combination determining process (S62) is completed, the CPU 50 determines whether or not the number of executions of the random number extraction process and the combination determining process has reached a specified number (10 in the present embodiment) (S63). As a result of the determination, when the number of executions of the random number extraction process and the combination determination process has not reached the specified number (S63, No), the CPU 50 executes the random number extraction process and the combination determination process (S61, S62) again. To do.

  On the other hand, when the specified number of times has been reached (S63, Yes), the CPU 50 performs a specific winning combination determination process (S64). This specific winning combination determination process is a process for determining whether or not there is a specific winning combination by a combination determination process performed a predetermined number of times. In particular, in the present embodiment, it is determined whether there is a winning combination including a trigger symbol 97 that triggers the transition to a new free game as the specific winning combination.

  Here, although it is determined whether or not the number of executions of the random number extraction process and the combination determination process has reached the specified number in S63, the processes of S61 and S62 are repeated until these processes reach the specified number of times. The number and order of batch processing for random number extraction processing and combination determination processing are not limited to this, and can be changed as appropriate. For example, random numbers for the specified number of times may be extracted at once, and the role determination process for the specified number of times may be performed at once. You may make it determine a combination. That is, any format may be adopted as long as random number extraction and role determination can be performed as many times as necessary when determining the contents of the effect in S64.

  Following the specific winning combination determination process (S64), the CPU 50 executes a stop symbol determination process (S65). In the stop symbol determination process, when it is determined that there is a specific winning combination in the specific winning combination determination process, the symbol that is displayed on the effective winning line L is stopped so that the specific winning combination is established at the last free spin. Is determined for each of the variable display units 22 to 25. Specifically, the CPU 50 sets the code number of the stop symbol for each reel 220 so that the symbol combination corresponding to the specific winning combination is established on the effective winning line L. To decide. Then, after the stop symbol determination process (S65) ends, the process returns to the bonus game process shown in FIG. 9 and proceeds to the free spin process of S52.

  In the batch lottery process shown in FIG. 10, the case where the batch lottery process is performed at the beginning of the bonus game process is shown, but such timing is an example, and the timing of performing the batch lottery process can be changed as appropriate. is there. For example, the batch lottery process may be performed by a normal game process or the like before the free spin process is started.

  Here, the free spin process executed in the bonus game process will be described with reference to FIG. As shown in FIG. 11, when the free spin process is started, the CPU 50 executes the same process as the normal game process (S13) shown in FIG. 5 in accordance with the player's predetermined operation. ) Is started (S71). As described above, it is not necessary to insert coins or press a bet button to start the symbol variation display.

  Following the symbol variation display start (S71), the CPU 50 performs a symbol variation display stop (S72) corresponding to the stop control process (S42) in the normal game process. In this symbol variation display stop, the CPU 50 determines the symbols to be displayed on each of the variable display units 22 to 25 in a state where the variation display is stopped, and determines the determined symbols (hereinafter referred to as “stop symbols” as appropriate). The stepping motor 68 and the motor drive circuit 167 are controlled to stop the reel 220 so as to be displayed on each of the variable display units 22 to 25.

  Next, when the stop symbol displayed on each of the variable display units 22 to 25 includes a predetermined symbol combination, the CPU 50 determines the number of coins paid out to the player according to the combination, or the player. A winning determination process for calculating the number of credits to be newly added to the number of credits on hand is performed (S73). Note that the timing for performing the winning determination process can be changed as appropriate, and any timing may be used between the batch lottery process (S51) and the next payout process (S16). good.

  In the winning determination process (S73), after calculating the number of coins to be paid out to the player, the CPU 50 executes an addition process for temporarily adding the number of coins to the payout coin (S74). When the processes from S71 to S74 are performed, one free spin process is completed.

  Returning to FIG. 9, the description of the bonus game process is continued. When the free spin process is completed as described above, the CPU 50 determines whether or not the number of executions of the free spin process, which is a condition for ending the bonus game process, has reached the specified number (10 in the present embodiment). (S53). As a result of the determination, when the number of executions of the free spin process has not reached the specified number (S53, No), the CPU 50 executes the free spin process (S52) again. On the other hand, when the specified number of times has been reached (S53, Yes), the CPU 50 ends the bonus game process and returns to the main process.

  When the process is repeated until the number of executions of the free spin process reaches the specified number, if it is determined that there is a specific winning combination in the specific winning combination determination process (S64) described in FIG. 10, the last free spin process The specific winning combination is stopped and displayed on the effective winning line L. That is, the winning combination including the trigger symbol 97 is stopped and displayed on the effective pay line L. When the winning combination including the trigger symbol 97 is stopped and displayed on the active winning line L, the bonus game process shown in FIG. 9 is performed again in the slot machine 1.

  Returning to FIG. 5, the description of the main process will be continued. In S14, when the bonus game is not established (S14, No), and when the bonus game process (S15) is finished, the CPU 50 adds the normal game process (S43) and the free spin process (S43). A payout process is performed in which coins corresponding to the number of payouts added to the payout-scheduled coins in S74) are collectively ejected, or a new payout amount is added to the number of credits held by the player (S16). Then, after performing the payout process, the CPU 50 returns the process to the start acceptance process (S11) and prepares for the next game start. This is the end of the description of the main process and the operation example of the slot machine.

  As described above, according to the slot machine 1 of the present embodiment, the lottery performed in accordance with the number of free spins during the free game is performed in a lump, and the winning pattern includes a specific symbol in the result of the batch lottery. If there is a winning combination, control is performed so that the winning combination is stopped and displayed at the last free spin. Thereby, since the expectation for the transition to a new free game can be maintained until the last free spin, it is possible to fully enhance the interest of the game during the free game.

  In particular, in the slot machine 1 according to the present embodiment, the specific winning combination including the trigger symbol 97 that triggers the transition to a new free game is controlled to be stopped and displayed at the last free spin. Thereby, since the expectation for the transition to a new free game can be maintained until the last free spin, it is possible to fully enhance the interest of the game during the free game.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning. In the above-described embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited to this, and can be appropriately changed within a range in which the effect of the present invention is exhibited. In addition, various modifications can be made without departing from the scope of the object of the present invention. The modification of this invention is illustrated below.

  In the above embodiment, the case where the winning combination including the trigger symbol 97 that triggers the transition to a new free game is controlled to stop and display at the last free spin as the specific winning combination is shown. As the specific winning combination, it is possible to designate another winning combination as appropriate. The specific winning combination designated here may be a winning combination that can give a player some kind of profit. For example, it is possible to specify a winning combination in which the winning number of coins is more than a certain number. Is possible. Even in this case, the expectation for the acquisition of a large amount of coins and the like can be maintained until the last free spin, so that it is possible to sufficiently enhance the interest of the game during the free game.

  In the above embodiment, the case where the batch lottery process is performed at the beginning of the bonus game process is shown, but the batch lottery process may be performed before the start of the free game. You may make it carry out during processing. In particular, by performing the batch lottery process at a timing when there is little arithmetic processing in the CPU 50, the arithmetic processing in the CPU 50 can be made more efficient.

  In the above embodiment, the slot machine 1 using a so-called mechanical reel is shown. However, the present invention includes display means capable of displaying an image, such as a liquid crystal display device, instead of the mechanical reel. The present invention can also be applied to a so-called video reel type slot machine that replaces a reel by displaying an image on a display means.
