Description

  The present invention relates to a slot machine and, for example, to a slot machine equipped with a bonus game of different types such as a super big bonus or a normal big bonus with different payout medals.

In this type of slot machine, when a player inserts a game medium such as a medal or a pachinko ball into the game medium slot and operates the start lever, the reel starts to rotate, and when the stop button is pressed, The reel corresponding to the push button stops rotating. When all the reels are stopped, a bonus game such as receiving a bonus game or a payout of game media that can possibly acquire a lot of game media is given by a combination of symbols appearing in the reel display window of the slot machine. The bonus game includes a big bonus game (hereinafter referred to as BB game) and a regular bonus game (hereinafter referred to as RB game). A general difference between a BB game and an RB game is that the number of game media that a player can acquire is several times different. When the player operates the start lever, it is determined whether or not any of these BB games can be given by random number drawing.

Only with the bonus game type of the BB game or the RB game, the gaming nature of the slot machine is uniform, and there is a possibility that the willingness to play is reduced. Therefore, for example, as shown in Patent Document 1, even if the same BB game is used, a variation can be made by further allocating to a super big bonus (hereinafter referred to as an SBB game) or a normal big bonus (hereinafter referred to as an NBB game) by lottery. Slot machines with many bonus game modes have appeared. In other words, in the NBB game, the number of game media acquired is a standard bonus game, and in the SBB game, it is a bonus game that can acquire more game media than the NBB game, and SBB and NBB are installed. As a result, the game nature of slot machines is diversified to enhance its interest.
JP 2003-135552 A

Conventionally, SBB and NBB are distributed when a bonus is won, or a predetermined game period is assigned as a challenge period for SBB acquisition before the bonus is won, and the big bonus won during the challenge period is designated as SBB. I went there. For this reason, although bonus games can be diversified by granting SBB and NBB, the game itself remains based on bonus lottery, and it cannot be said that it is sufficient to increase interest.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a slot machine having a playability that can enhance interest in relation to the distribution of the same-type bonus games having different payout medals such as SBB and NBB.

A slot machine including a storage unit and a cumulative value determination unit that determines whether or not the cumulative score value stored in the score storage unit exceeds a predetermined value, and the predetermined determination condition is that the cumulative score value exceeds the predetermined value It is.

According to the first aspect of the invention, the special game includes a first special game (for example, NBB) that can acquire a predetermined upper limit number of the game media (game medals, etc.) and a first special game state. A second special game (for example, SBB) that has a high possibility of acquiring a large number of the game media (game medals, etc.) is included, and the high-probability replay state control means determines that a predetermined game condition is satisfied and A winning combination that has occurred during at least a specific period of the gaming period in the high-probability replay state is shifted to a high-probability replay state with a higher probability of occurrence of a replaying role during a predetermined gaming period. It is determined whether the number of occurrences and the type of the generating role satisfy a predetermined determination condition, and a special game generated in the game after determining that the predetermined determination condition is satisfied is set in the second special game. Therefore, when giving the second special game, for example, when distributing SBB and NBB, a specific game is performed to determine whether the number of winning combinations generated during the specific period and the types of generated combinations satisfy a predetermined determination condition. The SBB can be given according to the specific game result, and the interest of the slot game can be enhanced. The special game only needs to include at least the first special game and the second special game, and in addition, a special game such as a regular bonus may be mounted.

According to the second aspect of the invention, the special game occurrence determining means determines whether or not a special game has occurred in the finite game period after the specific period, and the special game generated in the finite game period. Is set in the second special game, so that it is determined not only during the specific period but also after the specific period on the condition that the grant of the second special game is determined by performing the specific game in the specific period. The special game that occurred during the finite game period can be used as the second special game, and the opportunity to acquire the second special game, which is more advantageous by the player, can be provided in two stages. Thus, it contributes to an improvement in the operating rate of the slot machine. In addition, when it is determined to give the second special game by performing the specific game in the specific period, if the high probability replay state is still in effect, the finite game period after the high probability replay state ends However, the high-probability replay state may be terminated using the decision to grant the second special game as a cancellation condition, and the finite game period may be immediately transferred.

According to the third aspect of the invention, since the predetermined determination condition is that replay occurs at least three times continuously in the specific period, the high probability replay state in which the replay combination occurrence probability is high By implementing the specific game over a plurality of games using the specific period to determine whether or not to achieve the predetermined determination condition, it is possible to further increase interest.

The effect display device 203 is a double liquid crystal display device including a transmissive color liquid crystal display device constituting a front liquid crystal screen and a transmissive color liquid crystal display device constituting a rear liquid crystal screen. Drive controlled. The effect display device 203 is composed of a transmissive color liquid crystal display device 203a and a transmissive color liquid crystal display device 203b, which are stacked on the rear side of the front panel 203e, and each liquid crystal display screen is front and rear with a predetermined interval (about 2 inches). It is arranged in parallel with. A backlight light source 203d is provided behind the transmissive color liquid crystal display device 203b to illuminate the liquid crystal screen from the back side, and a cooling light as an intermediate light source is provided between the liquid crystal display device 203a and the liquid crystal display device 203b. An edge light source 203c made of a cathode tube is provided. Further, a liquid crystal driving driver circuit 330 described later is disposed on the rearmost side. These components are housed in a display unit case (not shown), and are mounted on the game board 5 as a display unit from the back side.

Although not shown, a polarizing panel is also provided between the liquid crystal display device 203a and the liquid crystal display device 203b to prevent image quality reduction such as color unevenness and moire fringes. The rear liquid crystal display device 203b does not necessarily have to be a transmission type, and the variable display device is not limited to a liquid crystal, and may use, for example, a color EL (electroluminescence). The screen may be composed of a transmissive color liquid crystal display device, and the rear display screen may be composed of a color EL, a color plasma display device, or the like.

FIG. 5 shows an outline of the control configuration of the effect display device 203 and the driver circuit 330. The driver circuit 330 is a display control circuit for driving and controlling each liquid crystal display device, and includes image data processors (VDP: Video Display Processors) 330a and 330b for effect display and variable display. The VDPs 330a and 330b include a sprite circuit for performing sprite processing of image drawing data, a color data processing palette circuit, a background processing screen circuit, and the like, and perform image display processing of the liquid crystal display devices 203a and 203b, respectively.
Connected to the VDPs 330a and 330b are image control ROMs 330c and 330g, character ROMs 330d and 330h for storing image data, VRAMs 330e and 330i as buffer memories for storing image data, and color palette RAMs 330f and 330j, respectively. .
The character ROMs 330d and 330h store various display image data such as special symbol image data, background image data, effect image data, and normal symbol image data indicating a normal symbol. The display image data consists of data designating the color of each dot with a color number. The color palette RAMs 330f and 330j store color data for each color number. The VRAMs 330e and 330i store data for designating which number of display image data is arranged in each area set in the image creation area of each VDP.

The VDPs 330a and 330b receive special symbol image data indicating special symbols, background image data, effect image data, and normal symbols indicating normal symbols from the character ROMs 330d and 330h in accordance with image display commands (control commands) supplied from the CPU 327. Various image data such as design image data is read out, and image data to be displayed on the liquid crystal display device is generated. Image data generated by each VDP is stored in the VRAMs 330e and 330i, and images are displayed by supplying these image signals (image frames) to the liquid crystal display devices 203a and 203b at a predetermined timing.

Each VDP executes display processing based on an image display command supplied from the CPU 327. With this display processing, an image signal for one image (one frame) is output each time the VDP 330a, 330b receives one control command from the CPU 327. In the display processing procedure, first, data to be displayed is specified from data stored in the VRAMs 330e and 330i based on the input control command, and an image creation area is set based on the specified data. Display data stored in the character ROMs 330d and 330h are arranged in each of the areas to be configured. Next, scanning lines are taken out one by one from the image creation areas of the display data arranged individually in the respective liquid crystal display devices 203a and 203b, and the color numbers of the display data constituting the taken-out scanning lines are set to the color palette RAM 330f, The data of 330j is used to convert to an image signal. The above processing is executed for all scanning lines, and the VDPs 330a and 330b output image signals to the liquid crystal display devices 203a and 203b.

As shown in FIG. 4, the liquid crystal display devices 203 a and 203 b constitute a multiplexed video screen in which the display screens are stacked, and a multiplexed video display process is performed by the driver circuit 330 using the stacked screen. The multiplexed video is performed by synchronizing the image display on the front display screen of the liquid crystal display device 203a and the rear display screen of the liquid crystal display device 203b. For example, multiple images can be displayed on the front and rear display screens so that the same or related symbols and character images are overlapped to display a three-dimensional design with a sense of depth, or from the front display screen to the rear display screen or vice versa. This is used to display a three-dimensional movement of a symbol or the like by switching the screen of the display symbol or the like so that the symbol or character image moves in the direction. The stereoscopic image image data of the character used for the multiplex video effect is stored in the character ROMs 330d and 330h.
Of course, the liquid crystal display devices 203a and 203b are also used independently. For example, the main effect display is performed on the front display screen, and at that time, the front display screen is made transparent or semi-transparent, and the rear display screen has a background. Or display an image. The transparent or translucent state of the display screen on the front side is a display mode in which there is no image display, a display mode in which a display area excluding image display of a part of the screen can be seen through, and the entire screen is displayed in a predetermined color Including a display mode for making a monotone screen.

A front panel surface DP is provided below the effect display device 203. A transparent window 207 is provided on the front panel surface DP so that the reels (rotors) 206a to 206c inside the housing can be visually recognized. The reels 206a to 206c are rotated by a stepping motor (not shown). The reels 206a to 206c are provided on the surface thereof with a predetermined number of symbols along the rotation direction. From the window 207, a predetermined number of, for example, three symbols among the symbols on the reels 206a to 206c are visible. The reels 206a to 206c constitute a rotating display unit that changes the symbols displayed on the window 207. In this example, a configuration is shown in which symbols are arranged on the surface of the reel and the symbols are changed by the rotation of the reel. However, the present invention is not limited to this, and a symbol is arranged on the surface of a rotating body, for example, a belt, and this is rotated. It is good also as a rotator display part which fluctuates a design. On the front panel surface DP, an effective line indicator that displays which line is valid, such as an effective line, that is, a line to be awarded when the number of medals for one game is set (FIG. (Not shown) is arranged on the front panel surface DP.

(3A), (3B), and (3C) in FIG. 3 respectively show symbol arrays attached to the reels 206a to 206c. The bonus winning symbol includes red 7 (for example, left reel symbol Nos. 9 and 11) and blue 7 (for example, left reel symbol Nos. 16 and 18). The small part winning design includes a bell design (eg, left reel design No. 6, 13, 20), a watermelon design (eg, left reel design No. 7, 14), a red cherry design (eg, left reel design). Symbol No. 17), blue cherry symbol (eg, left reel symbol No. 10), black cherry symbol (eg, left reel symbol No. 3), and replay symbol (eg, left reel symbol No. 3). 1, 5, 8, 12, 15, 19).

FIG. 6 shows a symbol combination of a winning combination in the slot machine A of the present embodiment and a payout table for a normal game. Each of the three types of big bonuses (BB1, BB2, BB3) is determined by a combination of three red, seven blue, two red seven symbols and a blue seven symbol stop symbol. The only regular bonus RB winning is determined by a combination of two stop symbols of red 7 symbols and blue 7 symbols. The big bonuses BB1 to BB3 are ended by acquiring a maximum of 420 award medals, and the regular bonus RB is ended by acquiring a maximum of 120.

FIG. 7 shows a small role lottery probability table in the bonus game (BB or RB). In the bonus game, the replay role is not won, and the small role (such as watermelon) except the bell is won with a low probability, but in most cases, the bell role overlaps with the other cherry-related winning roles. The lottery probability of the red cherry role (role No. 8, 9 in FIG. 6) is approximately 1 / 3.0, and the lottery probability of the blue cherry role (role No. 10, 11 in FIG. 6) is approximately 1/3. It is 0, and the lottery probability of the black cherry combination (the combination No. 12 in FIG. 6) is approximately 1 / 3.0. These five types of cherry roles (combinations Nos. 8 to 12 in FIG. 6) have a lottery probability of approximately 1 / 1.0 in terms of the composite probability, and are drawn so that any one of the cherry roles can be easily won. That is, during the bonus game, one of five types of cherry roles (payout number: 15) and a bell (payout number: 7) are won almost simultaneously. Therefore, the player performs the reel stop operation aiming at the cherries with a large number of payouts, but if the winning cherries are missed due to a mistake in the line, etc., the winning symbol pull-in control is executed so that the bells are aligned. The situation where the medal acquisition does not occur is prevented.

When the bonus game is generated, the big bonus BB1 is a super big bonus SBB, and the big bonuses BB2 and BB3 are normal big bonus NBBs. During the game of BB1, the notification (navigation) of the type of winning cherry (red, blue, black) is executed every time it is won. In NBB, you have 3 choices for cherry blossoms. In SBB, as long as the winning type is not missed by notification of the winning type, it is possible to reliably win a small role winning with a large number of payouts, and to finish the bonus game with a minimum of medal consumption. Therefore, the player is going to seek the winning of BB2 and BB3 and the winning of BB1 from RB. Cherry-type navigation effects are performed through the liquid crystal screen of the effect display device 203, and are implemented by displaying winning cherries by color on the screen immediately after the start of the game during the bonus game. Note that. BB2 and BB3 are NBB at the time of the bonus game, but even after bonus-in, the first chance game to SBB will be implemented in the first 10 games, and the correct answer will be 5 out of 10 3 choices If the winning cherry role is acquired, it will be upgraded to SBB from the 11th time, and in subsequent bonus games, you can receive navigation for the correct cherry.

The cherry winning combination includes a combination with a bell symbol, but the bell symbol is arranged within 4 frames that can be pulled in, and when it wins, it substantially stops on the active line of the left reel 206a. It corresponds to a single role that is established. Therefore, even if the player is notified in advance of the cherry win, the player will stop the left reel by relying on one of the three types of symbol colors. The red and blue cherry symbols are arranged at positions sandwiched between a pair of bonus winning symbols red 7 and blue 7 so that the eye-pressing operation at this time is relatively easy (the symbol No. of the left reel). 9-11, 16-18), and each black cherry symbol is placed at a position sandwiched by black 7 (left reel symbol Nos. 2 and 4) that has nothing to do with bonus winning (left reel symbol No. .2-4).

  Below the window portion 207 is provided an operation panel provided with an operation portion operated by the player during the game. This operation panel includes an upper operation panel surface PN1 and a front operation panel surface PN2. On the upper operation panel surface PN1, a bet number setting switch 208 (1 bet switch 208a, MAX bet switch 208b) for setting the number of medals as a game medium provided for one game, a display for displaying the number of medals, etc. A device 209, a medal slot 210 for inserting medals, and the like are provided. The 1-bet switch 208a is for adding the number of medals bet in one game one by one by operating this switch. The MAX bet switch 208b is for setting the maximum number as the number of medals bet in one game. When the MAX bet switch 208b is pressed and the remaining number of medals is sufficient, the bet number is set to the maximum bet number, that is, three. When the remaining number of medals is less than the maximum bet number, all remaining medals are added to the bet number.

  The display 209 is composed of a segment display device or the like, and displays the number of medals to be paid out (the number of payouts), the number of medals that have been inserted and stored electronically (the number of credits), and the like. The slot 210 is formed so that game medals can be inserted one by one. The medal guide groove reaching the medal insertion slot 210 is provided so as to be inclined upward toward the insertion slot and obliquely outward toward the rear.

  Next, the operation of the slot machine A during a game will be described. During a game, the player first inputs a predetermined number of medals from the medal insertion slot 210 and then operates the start switch 211. At this time, lottery is performed inside the gaming machine and the reels 206a to 206c are rotated. After each reel reaches a certain speed, the operation of the stop switches 212a to 212c becomes effective, and each corresponding reel stops based on the timing of each operation and the lottery result inside the gaming machine. When one of the winning combinations is won, a predetermined number of medals are paid out if the winning combination is established on the active line in a timely manner. Further, the slot machine A electronically stores the number of medals inserted from the medal insertion slot 210 in a storage unit inside the gaming machine up to a predetermined number, for example, 50, and this number is displayed on the display 209. The function to display is provided.

  The main control unit 301 drives the display unit 209, the reel driving unit 324, the payout device 337, the door unit opening notification unit 325, the abnormality notification lamp 326 and the like via the driver circuit 323. As described above, the display unit 209 displays the number of credits during the game, but the setting value is displayed in the setting change mode. In addition, the display 209 is configured so that information on an abnormality that has occurred in each part of the gaming machine is displayed as an error code. When an abnormality occurs, priority is given to the display of the number of credits and the set value. Then, it is controlled by the main controller so that the error code is displayed.

  The reel driving unit 324 includes a left reel driving unit 324a, a middle reel driving unit 324b, and a right reel driving unit 324c that are provided corresponding to the reels 206a to 206c, respectively. Each of the reel driving units 324a to 324c has a stepping motor, rotates the reel in accordance with the operation of the start switch, and displays predetermined symbols on the reel in the window unit 207 in accordance with the operation of the stop switch. The stepping motor is driven and controlled to stop in the state. The door part opening notification device 325 includes an LED or the like for notifying that the door part 225 is open. By turning on the door opening alarm 325, forgetting to close the door 225 can be prevented. The abnormality notification lamp 326 includes an LED or the like for notifying a control abnormality or a gaming state abnormality occurring in the gaming machine.

  The first sub-control unit 302 is connected to the main control unit 301 via the relay board 304 and receives the signal from the main control unit 301 and controls the effect display device 203 and the like. The first sub-control unit 302 includes a CPU 327 that controls the overall operation of the first sub-control unit 302, a ROM 328 that stores effect display data and the like, a RAM 329 that temporarily stores the state of the effect being executed, and the like. An effect display device 203 is connected to the first sub-control unit 302 via a driver circuit 330. The effect display device 203 receives a drive signal from the first sub-control unit 302 and displays an image on the liquid crystal. Control is performed so that frames are read sequentially. By this control, an effect display related to the lottery result of the main control unit is performed. The various effects include game effects such as a display of a winning combination performed at the time of reel start, reel rotation, or reel stop, a congratulation display when a winning combination is established, a progress display during bonus, and the navigation display.

In the slot machine A according to the present embodiment, the first sub-control unit 302, the driver circuit 330, and the effect display device 203, depending on one of the game effect display patterns stored in the ROM 328, according to the lottery result. An effect display control means for performing a game effect display corresponding to the lottery result is configured. The display patterns stored in the ROM 328 include various game effect patterns such as navigation display during a bonus game.

  The second sub-control unit 303 is connected to the main control unit 301 via the relay board 304 and the first sub-control unit 302, and receives signals from the main control unit 301 and controls speakers and lamps. It has a function. The second sub-control unit 303 includes a CPU 331 that controls the overall operation of the second sub-control unit 303, a ROM 332 that stores effect data and the like, a RAM 333 that temporarily stores the state of the effect being executed, and the like. An upper speaker 204, a lower speaker 217, an effect lamp 335, and the like are connected to the second sub control unit 303 via a driver circuit 334, and the second sub control unit 303 drives these to perform effect control. .

  Next, the operation of the slot machine A during the game will be described below. FIG. 8 is a flowchart showing the control of the main control unit during the normal game. First, in order to start a game, a betting number setting process (step S100) is performed. When the bet number is set, the operation of the start switch becomes effective. When a medal is newly inserted from an unplayed state in which no bet number is set, this medal is detected by the medal sensor 320, and up to three inserted medals are automatically set as the bet number. When the re-gamer wins in the previous game, the bet number is automatically set, so the bet number setting process is not performed. In cases other than the above, when the player presses the bet number setting switch 208, the number of medals operated from the credit number storage unit is subtracted, and the number of bets is set as the bet number. The remaining number of credits is displayed on the display 209. At the same time, the winning line corresponding to the number of bets is activated, and that effect is displayed on the activated line display. The bet number can be changed until the start switch is operated.

  After the betting number setting process (step S100), the operation of the start switch 11 is waited (step S101). When the start switch 211 is operated, a lottery process (step S102) and a reel rotation process (step S103) are performed. In this lottery process, random numbers generated by a random number generator included in the CPU of the main control unit are extracted at the operation timing of the start switch 211, and based on a lottery table stored in the lottery table storage unit 311 of the ROM of the main control unit. This is the main lottery process for determining whether or not the game is successful. Which lottery table is used as the lottery table differs depending on the value in the set value temporary storage unit 315. The lottery result determined based on the lottery table includes a small role for paying out a predetermined number of medals, a re-gamer that can execute the next game without inserting a new game medium, and a predetermined game from the next game. The number includes a bonus combination for starting a bonus game that increases the winning probability of the small combination, and a miss. And according to each combination, a symbol combination to be aligned on the effective line is determined. In the following description, the determination of each winning combination by lottery is called “winning”, and the combination of symbols corresponding to the winning combination on a predetermined effective line is called “winning”.

  The reel rotation process in step S103 is a process of rotating the reels 206a to 206c by transmitting a drive signal to the reel drive unit 324. By this reel rotation processing, the stop switch operation becomes effective after the rotation speed of the reel becomes constant. Subsequently, in step S104, it is detected whether or not the stop switch 12 has been operated. And when stop operation is performed, the stop control process (step S105) which stops the reel corresponding to stop operation is performed. This stop control process refers to the reel stop table stored in the ROM 306 based on the stop operation position, which is the position where the stop operation has been performed for each reel, and the result determined in the lottery process. Thereafter, the rotation of the reel is stopped at the reel stop position). The reel stop position is determined so as to stop within a predetermined number of symbols, in this case within 4 frames, as viewed from the stop operation position. When there are symbols corresponding to the lottery result within 4 frames from the stop operation position, stop control is performed so that the symbols are aligned on the effective line. In this stop control process, when the re-gamer is won even in the bonus flag carry-over state, control is performed so that the re-gamer is always aligned on the active line. When the winning of the bonus flag and the winning of the small role occur at the same time due to duplicate winning by lottery or carryover of the bonus flag, control is performed so that the bonus symbols are preferentially aligned. In FIG. Twelve black cherries are a single winning combination, and only by stopping on the left reel, a small cherry is awarded.

  Next, in step S106, it is determined whether all the reels 206a to 206c are stopped. If not stopped, the process returns to step S104 to perform stop control processing. If all reels are stopped, it is determined in step S107 whether or not the winning symbol is on the active line. In the case of winning, a winning combination is determined in step S108. If the winning combination is a small combination, the payout device 337 is driven to pay out a predetermined number of medals (step S109). On the other hand, if the winning combination is a re-game player, an automatic bet number setting process for automatically resetting the bet number set in the current game as the bet number in the next game is performed in step S112. In this case, since the number of credits is not subtracted from the credit, the next game can be played without inserting a new game medium (including the consumption of credit). Since the next game bet number setting process is automatically performed, the bet number setting process is not performed in the next game. If the winning combination is a bonus, the bonus game mode is set, and the next game is shifted to the bonus game.

If the determination in step S107 is NO (non-winning), if a bonus is won by lottery in step S110, that is, a bonus is won in the lottery but is not aligned on the effective line as a result of stop control. If YES, the carry-over process is performed in step S111. This carry-over process is performed by storing the establishment of the bonus flag in the RAM of the main control unit. In a game in which the bonus flag is established, the number of established bonus flags is not added even if the bonus is won. The memorization of the bonus flag is continued until the bonus combination is won.

As shown in FIG. 7, the bonus game mode is a mode in which the random number width corresponding to the small combination is changed by changing the lottery table used in step S102. As a result of this change, the probability of winning a cherry-related small role by lottery has been greatly increased. During this mode, bonus lotteries will not be drawn or will be invalidated, and the bonus game will be Since a small role is frequently won, it is an advantageous state for a player to obtain a large amount of medals.

Next, the bonus game process will be described with reference to FIG. The processing from the start to the stop of the reel (steps S113 to S119) is the same as the processing from step S100 to step S106 in FIG. If the determination in step S119 is yes, it is determined in step S120 whether or not a winning according to the lottery is established on the active line. The occurrence frequency when there is no winning combination is very low. In this case, the process returns to step S113 to play the next game. If there is a win, the winning combination is determined in step S121. If the game is replayed, an automatic betting number setting process is performed in step S122, and the process returns to step S113 to play the next game. In the case of a small role, the payout device 37 is driven in step S123 to pay out a corresponding number of medals, and in step S124, it is determined whether or not the bonus game has ended. Here, the bonus game is terminated when the added value of the payout number reaches the upper limit number (for example, 420 for BB1 to BB3). For this reason, every time a small role is established, the payout number is counted in the RAM of the main control unit, and when the predetermined number is reached, the bonus game is canceled and the game returns to the normal game.

Next, bonus game type determination processing in the present embodiment will be described. When the big bonus BB1 is won in the lottery process in the normal game, the SBB bonus game with navigation is automatically executed. However, when the BB2 or BB3 is won, the bonus flag FG is established and the game moves to the SBB upgrade chance game. When an upgrade chance is acquired in the SBB upgrade chance game, the big bonus form of BB2, 3 is changed from NBB to SBB.
FIG. 10 shows the SBB upgrade chance game process (SBB / NBB bonus type determination process) when the bonus flag FG is established. When the bonus flag FG is established by winning the bonus, the subsequent gaming state is set to the RT mode in the RT (replay time) state (steps S200 and S201). The SBB upgrade chance game is a point acquisition game different from the original medal acquisition game. (11A) in FIG. 11 shows a point game scoring table. Each small role, etc. is assigned a point role, and the score of the point role is 3 points for Replay RP, 9 points for Cherry-related small role CH, 2 points for Bell small role, and 8 points for watermelon role .

  The RT game is a game in which a high probability replay state in which the probability of replay winning is increased by switching the random number width of the lottery table and the occurrence probability of the replay role is higher than in the normal game is set. During the RT game, a replay is won with high probability, so that a bonus win can be expected with a small amount of medal consumption. The replay probability is set to 1 / 7.3 in the normal game, but increases to 1/2 in the RT game. In this case, the probability of a combination other than replay, a bonus game (substantially excluded from a lottery when the flag is established) and a small role does not change, but the random number area assigned to the offside is assigned to the replay. RT in step S201 is set when the bonus flag FG is established, and the number of continuations of the RT game continues until the bonus winning, and the RT state is canceled by the bonus winning and ends.

  When the RT is set, the point processing effective period in which the point calculation is performed is determined, and the number of times is notified (step S202). (11B) in FIG. 11 shows a selection table of the number of points calculation game effective times. This table and the point game scoring table of (11A) are stored in the ROM 327 of the first sub-control unit 302. Each small role, etc. is assigned a point role, and the score of the point role is 3 points for Replay RP, 9 points for Cherry-related small role CH, 2 points for Bell small role, and 8 points for watermelon role . When the number of points acquired during the game of the selected point calculation game after entering the RT state becomes 10 points or more, the player can obtain the SBB upgrade right. It should be noted that the difficulty point may be adjusted by various selections by lottery without fixing the target point value for obtaining the SBB upgrade right.

When one reel rotation / stop game is executed (step S203), SBB upgrade confirmation processing is performed (steps S204 to S212). When the point calculation game remains and the bonus symbols are not yet available, the number of points acquired by the game is displayed on the screen of the effect display device 203 to notify the player (steps S206 and S210).
FIG. 12 shows a screen display example of the effect display device 203 in the SBB upgrade chance game. (12A) of FIG. 12 is an SBB upgrade chance game start screen at the time of RT entry, in which 5 games of the effective point calculation game number and a target point number of 10 are notified. FIG. 12B is a notification screen when, for example, 3 points are acquired by establishing RP in the second game. On this screen, the remaining value 7 to be further acquired by the player is also notified.

  In the state where the bonus flag FG is established, if the bonus symbols are aligned, the game shifts to a bonus game. Therefore, the SBB upgrade chance game can be continued until the bonus symbols are aligned (step S211), and the point calculation game remains. If so, the next point calculation game is entered. When the point calculation game has been completed for the selected number of times, a comparison determination is made between the total number of acquired points and the target predetermined value (10 points) at that time (steps S204 and S212). If the total number of acquired points has reached the target value, SBB upgrade is determined (step S213), and if not, NBB is determined (step S214). Even when the point calculation game has not finished the number of selections, a comparison determination between the total number of acquired points and the target predetermined value is performed at that time (steps S204 and S205). Of course, if the total number of acquired points has reached the target value, the SBB upgrade is determined (step S213), and if not, the point game is continued (step S203). (12C) of FIG. 12 shows an example of a blessing screen when the SBB upgrade is determined by the achievement of the target. FIG. 12D shows an example of the SBB acquisition confirmation screen displayed after the blessing screen 12C.

  After the bonus type is determined, the game ends even if the point calculation game remains, and the RT state continues until the bonus symbols are complete (steps S206, S207, and S203). When the bonus symbols are aligned and the bonus-in state is established, the RT mode is canceled and the game state is shifted to SBB or NBB (steps S207 to S209). The number of games in the RT mode may be set to a finite number equal to or greater than the maximum finite number of games (seven times) of the SBB upgrade chance game.

  FIG. 11 (11C) schematically shows an example of a game pattern of successful SBB upgrade. In the drawing, a series of flow from the establishment of the bonus flag FG to the SBB bonus game through the point calculation game is shown. From the game when the bonus flag FG is established, the display on the effect display device 203 informs that a big bonus other than the big bonus BB1 has been won, and informs the start of five point calculation games A5. In subsequent games, the process proceeds to the high probability replay state A4. If the lottery is drawn at the same time as the cherry lottery, all winning symbols can be pulled in, so if you win and win the bonus symbol immediately, you will be transferred to the bonus game. To do. In the case of (11C), it is a point calculation game that is performed when the transition to the bonus game is not performed, but of course, since the bonus flag FG is established, the winning bonus symbols are aligned by chance even during the point calculation game. If this happens, the game will shift to a complete bonus game, and the player will need to keep his eye on the BB2 or BB3 symbols. In particular, not only when winning a small role / replay failure, but also when winning a small role such as a bell, the winning bonus symbol with the bonus flag FG is preferentially drawn, so the winning bonus symbol is not drawn. In this way, it is necessary to make a small role.

In the case of (11C), the bell is won the first time and the second time of the point calculation game, and the bells are aligned by avoiding the symbols of BB2 or BB3. Unlike the replay role, bells and other small roles are not pulled in and controlled prior to the winning bonus symbol. For example, even when the bell is elected, the symbols BB2 or BB3 may occur, and in that case the point calculation game is interrupted. To shift to the BB2 or BB3 bonus game. In the third and fourth games, it is notified that the replay role has been won and the total score has reached 10 points. Further, as shown in (12C) of FIG. 12, an SBB acquisition notification (A1) is performed. Is called. Thereafter, when the player pushes and arranges the winning bonus symbol BB2 or BB3 (A2), the game shifts to a bonus game A3 by SBB upgraded from NBB.

  (13A) of FIG. 13 schematically shows an example of a game pattern of SBB upgrade failure. In this example, as in (11C) of FIG. 11, the point calculation game A5 is awarded five times by the establishment of the bonus flag FG, and Bell is won in the first and second point calculation games, and BB2 or BB3 This is a case where the bells are aligned by avoiding the pattern. In the next third game, the small role or replay role will not be elected and will be lost, and then in the fourth game, the replay role will be elected. At that time, the total number of points became 7 points, but unfortunately This is an example in which the final game is also a lottery lottery and the NBB is confirmed with a game result of less than 10 points. After the notification of the end of the point calculation game and the notification A6 of NBB determination are performed, when the player presses and aligns the winning bonus symbol BB2 or BB3 (A7), the game shifts to a bonus game A8 by NBB without SBB upgrade.

  FIG. 13 (13B) schematically shows an example of a game pattern of successful SBB upgrade. In this example, unlike (11C) of FIG. 11, when the bonus flag FG is established, three point calculation games A9 less than (11C) are awarded. In the three point calculation game, it is a very disadvantageous condition for the player that the SBB upgrade is impossible due to the formation of the replay role three times. In addition, the bell is won in the first and second point calculation games, and the bells are aligned by avoiding the symbols BB2 or BB3. This is an example in which the cherry blossom was won in the third final game and the SBB was finalized as a result of the total number of points being 13 and reversed. In this case, the winning cherry is the role No. in FIG. Limited to 12 black cherries alone. After the notification of the end of the point calculation game and the notification A10 of the SBB determination are performed, when the player pushes and aligns the winning bonus symbol BB2 or BB3 (A11), the game shifts to the bonus game A12 by the NBB upgraded SBB. An unexpected SBB upgrade game can be implemented by providing various game patterns by combining a reverse pattern by winning (winning) a cherry or watermelon with a relatively large number of points with the number of point calculation games.

  During a normal game, a bonus type determination chance game (hereinafter referred to as a chance zone CZ) that gives an opportunity to upgrade the SBB is given to the player. All bonuses won during the chance zone CZ will be SBB. The chance zone CZ is generated when the big bonus BB1 ends, when the replay role is established three or four times continuously, when no bonus is generated after the big bonus game ends, or when the regular bonus ends This is the time when 555 games have passed without any bonuses. At the end of the big bonus BB1, 50 or 100 chance games CZ are awarded by lottery. When the replay combination is continued three times, 50 chance games CZ are awarded, and when the replay combination is continued four times, 100 chance games CZ are awarded. When 777 games or 555 games have elapsed, an unlimited number of chance games CZ are awarded. When each occurrence condition overlaps, all are added (additional update). For example, if 100 CZs are selected after the end of BB2, and after 20 games have been digested, if the replay role continues three times, the CZ of 130 (= 100-20 + 50) games continues thereafter. For example, after the replay role has been repeated 3 times and entered 50 CZs, if the replay role has been continued 4 times after digesting 30 games, the CZ of 120 (= 50-30 + 100) games continues thereafter. .

  In the present embodiment, in addition to the chance zone CZ generation condition, a game process (CZ acquisition chance game) that gives an opportunity to shift to CZ (50 games) through a pre-chance game is also included. FIG. 14 shows a game process of the CZ acquisition chance game. The generation conditions of the CZ acquisition chance game are the role of red cherry (role No. 8, 9 in FIG. 6), role of blue cherry (role No. 10, 11 in FIG. 6), and role of black cherry (role No. 12 in FIG. 6). Is to win a lottery with a lottery probability 1/4. Of course, 100% CZ acquisition chance game may be generated by winning the cherry role. If the occurrence condition of the CZ acquisition chance game is satisfied (step S300), the RT state is set for the number of 10 games (step S301), similarly to the SBB upgrade chance game processing when the bonus flag FG is established in FIG. Similar to the SBB upgrade chance game, the CZ acquisition chance game is a point acquisition game different from the original medal acquisition game. The game score is the same as the point game score table of FIG. 11 (11A). In this case, a point table different from (11A) may be used. Even in this RT game, the replay probability is as high as ½.

Also in the CZ acquisition chance game, the point processing effective period in which the point calculation is performed is determined, and the number of times is notified (step S302). This number of times is selected based on the point calculation game effective number selection table similar to (11B) of FIG. This table and the point game scoring table are stored in the ROM 327 of the first sub-control unit 302. When the number of points acquired during the game of the selected point calculation game number after entering the RT state becomes 10 points or more, the player can obtain CZ. Note that the difficulty may be adjusted by various selections by lottery without fixing the target point value for obtaining CZ.

When a single reel rotation / stop game is executed (step S303), CZ entry confirmation processing is performed (step S304). If the CZ has been entered, the CZ acquisition chance game is ended after continuing until the RT set number (10 times) has been fully consumed (step S305). If the CZ has not yet been entered (step S304), the number of points acquired by the game is displayed on the screen of the effect display device 203 to notify the player (step S306).
FIG. 15 shows a screen display example of the effect display device 203 in the CZ acquisition chance game. (15A) in FIG. 15 is a CZ acquisition chance game start screen at the time of RT entry, in which 5 games of the number of valid points calculated and the target point number (10) are notified. FIG. 15B is a notification screen when, for example, 3 points are acquired by establishing RP in the second game. On this screen, the remaining value 7 to be further acquired by the player is also notified.

Even during the CZ acquisition chance game, the above-mentioned chance zone CZ generation conditions are also effective and are confirmed to be established (steps S307 to S310). At this time, when the replay combination has already been performed four times, 100 chance games CZ are notified (step S308), and when the replay combination has been performed three times, 50 chance games CZ are notified. (Step S310). After the chance game CZ is granted, the CZ acquisition chance game is ended after the RT set number of times is fully consumed (step S305).

If the chance zone CZ generation condition is not satisfied, it is determined whether or not the total number of points satisfies the target value. If not, it is determined whether or not the point game number needs to be extended (steps S309 and S311). In other words, in the present embodiment, during the CZ acquisition chance game, one of the red cherry role, the blue cherry role, and the black cherry role is won, and at the same time, a bonus or the like is not won. The number of point games is extended (steps S312 and S313). For example, even if the red cherry role is won in the final point game, but the target value has not been reached, three additional games are executed later. When there is no additional game and the point game is terminated, the CZ acquisition chance game is terminated after the RT set number of times is fully consumed (steps S314 and S305).

It is determined whether or not the total number of points satisfies the target value, and if so (step S311), the status of the chance zone CZ generation condition is confirmed. That is, if there is a possibility that the replay combination will continue four times due to the continuation of the point game, the entry to 50 chance games CZ is temporarily suspended (step S315), and the point game is continued. This is because the CZ hold enters the chance game CZ 100 times when the replay combination is continued four times. If there is no possibility that the replay role will continue four times, the entry to 50 chance games CZ is notified (step S310), and the CZ acquisition chance game is ended after continuing to use all the RT set times. (Steps S314 and S305). (15C) of FIG. 15 shows an example of a blessing screen when the chance game CZ is determined by achieving the goal. FIG. 15D shows an example of the CZ confirmation screen displayed after the blessing screen (15C).

(16A) of FIG. 16 schematically shows an example of a game pattern in which a chance zone CZ is generated from a CZ acquisition chance game and the SBB is successfully upgraded during CZ. In this example, when the CZ acquisition chance game is started, the RT state B4 is set 10 times and the point calculation game B5 is given 5 times. Bell wins the first and second points calculation game, and then the RP role is continuously established and reaches the target value. There is one remaining game, but even if continuous RP is established, it is 50 times. Therefore, the CZ is not put on hold, and the rush of 50 CZ states B6 is notified as it is (B1), and the state shifts to the CZ state. Thereafter, when the big bonus is won during the CZ state B6 and the winning bonus symbol BB2 or BB3 is pressed and aligned (B2), the game shifts to the bonus game B3 upgraded from NBB to SBB. Of course, when the big bonus BB1 is won during the CZ state B6, the game shifts to the SBB bonus game regardless of the CZ. If the SBB bonus is won during the CZ acquisition chance game, the CZ acquisition chance game is ended and the SBB bonus is transferred. Further, when a bonus that is not an SBB is won during the CZ acquisition chance game, it is preferable to end the CZ acquisition chance game and shift to the SBB upgrade chance game shown in FIG. In this case, the acquired points up to the middle may be suspended and added to the points acquired during the SBB upgrade chance game.

(16B) of FIG. 16 schematically shows an example of a game pattern in which a chance zone CZ is generated from a CZ acquisition chance game and the SBB upgrade fails during CZ. In this example, as in (16A), when the CZ acquisition chance game is started, the RT state B4 is set 10 times and the point calculation game B5 is given 5 times. Lost lottery in the first and second point calculation games, then 3 consecutive RP roles are reached, reach the target value, get 50 CZs, and enter 50 CZ states B6 is doing. After that, when the big bonus is not won during the CZ state B6 and the game returns to the normal game state B8 after the end of the CZ, when the bonus symbol BB2 or BB3 is won and the symbols are aligned (B2), the game shifts to the bonus game B7 by the NBB. To do. Of course, of course, when the big bonus BB1 is won in the normal gaming state, the game shifts to the SBB bonus game regardless of the gaming state.

FIG. 17 schematically shows an example of a game pattern in which an additional game occurs in the CZ acquisition chance game and the chance zone CZ is acquired in the additional game, but the SBB upgrade fails during the CZ. In this example, when the CZ acquisition chance game is started, the RT state B4 is set to 10 times, and the point calculation game B9 is initially given 3 times. Lost lottery results for the first and second point calculation games will not reach the target value even if the RP is won in the final game, but the remaining one game will win the red cherry role, and three additional games B10 Is granted. Then, RP is won in the first game of the additional game B10, the total number of points exceeds 10, and 50 CZs are acquired.
