Description

  The present invention relates to a slot machine that performs a spinning reel (reel) stop game using a game medium such as a medal or a pachinko ball.

In this type of slot machine, a game is played by betting a predetermined number of game media (hereinafter described in the case of using medals) during a normal game, and when winning a winning lottery, for example, a big bonus (hereinafter referred to as BB). Or a special bonus state (hereinafter referred to as RB) or the like that makes it easier to obtain medals. In the special game state, the winning probability of the small role to which the game medium is paid out is higher than usual, and BB is a bonus prize that is obtained several times more medals or the like than RB. If BB or RB is won, it is possible to shift by winning a winning combination with symbols that establish these combinations.

In the conventional slot machine, as shown in Patent Document 1 and the like, when the winning symbol (the symbol corresponding to the winning combination won in the winning combination lottery) is located within a preset pull-in range, the rotation stop button is pressed. When the key is pressed, reel stop control is performed so that the winning combination wins. For this reason, when winning a BB or RB, if the BB symbol constituting the BB or the RB symbol constituting the RB depresses the stop button outside the pull-in range, it is not possible to win.

When a bonus is won, a bonus flag is established inside the slot machine, but even if the bonus win is notified early, it is common to notify the player of the winning bonus type when several games have elapsed since the bonus flag was established. Is. For this reason, the player guesses which of BB or RB is won, and performs a so-called push button operation for stopping the rotation. Also, in the slot machine, if the BB or RB cannot be won, the right won for these will be carried over to the next game and the BB and RB will be internally won in the next game. Become. However, when BB or RB is won internally, BB or RB lottery will not be performed, or even if BB or RB is won, it will be cancelled, so that the player can use the winning bonus as much as possible. If it is not established quickly, it will lead to medal loss.

By the way, in order to avoid being unfair to the player, it is possible to increase the winning probability of replay (replay) in the gaming state after the bonus flag is established, reduce the loss lottery rate, and suppress the player's medal loss. Has been done.
However, regardless of the type of BB and RB, after the bonus flag is established, the replay winning probability is uniformly increased, and in general, when the replay is won, the replay establishment is controlled to stop in preference to the bonus winning. Therefore, as more replays occur, the bonus winning is delayed, and there is a problem that the interest of the game is lowered when the RB wins instead of the BB.

In view of the above-mentioned problems, the present invention provides a slot machine that can enhance the interest without making the game process monotonous from when the BB or RB bonus flag is established until the player wins the winning bonus. The purpose is to provide.

According to a first aspect of the present invention, there is provided a rotating display unit for variably displaying a plurality of symbols, and after setting a betting number of game media necessary for a player to perform a rotating game, the rotating display unit A winning combination deciding means for performing a lottery based on a predetermined lottery probability and determining one of a plurality of winning combinations and replays predetermined according to the lottery result using the starting operation of , Determined by the spinning cylinder stop control means for performing stop control for stopping the spinning cylinder display unit based on the player's stop operation, the stop mode of the symbols stopped by the spinning cylinder stop control means, and the winning combination determining means. When the display mode of the symbol corresponding to the winning combination matches, the winning determination means for determining that the winning combination is established, the occurrence of the internal winning state in which the special winning combination or the specific winning combination is internally won, and the Announcer to notify the winning category In addition to a plurality of types of general winning combinations, the plurality of winning combinations include a special winning combination that gives a special game advantageous to the player after winning, and a smaller amount of game media than the special game. In a slot machine including a specific winning combination for granting a specific game, a variable winning trigger that makes the number of games that reduce the chance to win the special game or the specific game variable after the occurrence of the internal winning state is variable. After notifying the occurrence of the internal winning state and variable informing means for varying the number of games until the special game or the winning type of the specific game is notified in the internal winning state; The rate of increase in the number of games played by the variable winning opportunity stretching means and / or the variable rate in the variable notification means differ depending on the special winning combination or the specific winning combination in the internal winning state. It is a slot machine that.
The special game and the specific game according to the present invention are bonus games with different bonus flags, for example, BB and RB that differ in the number of medals obtained several times. In addition, the present invention can be applied to a case where the number of obtained medals is significantly different even when the winning combination during the bonus game is distributed to a so-called super BB (SBB) and a normal BB (NBB) that is not notified. . BB and RB are not limited to a single type, and a plurality of types of BB or RB may be mounted.

According to a second aspect of the present invention, in the first aspect, when the variable winning opportunity extending means is a re-winning game by lottery in the internal winning state of the special winning combination, Stop control of the stop mode that establishes the general winning combination according to the timing of the stop operation when performing stop control of the stop mode that establishes replay regardless of the timing and winning any of the general winning combinations Control is performed prior to the establishment of the special winning combination, and in the internal winning state of the specific winning combination, when the re-game is won by lottery, the re-game is established regardless of the timing of the stop operation. When stop control is performed and one of the general winning combinations is won, the stop mode is stopped so that the special winning combination symbol is established according to the timing of the stop operation. Controlling a slot machine consisting of priority stopping control means for performing in preference to establishment of the general winning combination.

According to a third aspect of the present invention, in the first or second aspect, the variable prize opportunity extending means performs a lottery based on a lottery probability that a replay lottery probability is higher than that in the normal game. This is a slot machine comprising replay high probability state setting means for setting a replay high probability state.

According to the first aspect of the invention, in addition to a plurality of types of general winning combinations (so-called small roles such as bells and cherries), a special game advantageous to the player after winning a prize is given to the plurality of winning combinations. In a slot machine including a special winning combination to be granted (for example, BB) and a specific winning combination to give a specific game (for example, RB) with a smaller amount of game media than the special game, in the internal winning state For example, the game period from when the bonus flag is established to when the bonus is won is extended by the variable winning opportunity extending means, and after the bonus winning notification is made, the bonus type is confirmed and the winning is extended. Since the period and / or the timing of the final notification is variable depending on the internal winning status of the special winning combination or the specific winning combination, it is possible to determine whether BB or RB has been won. The player can infer from the length of the extension period by the means for extending the winning opportunity and the delay of the final notification time, even if the bonus winning opportunity is slightly extended or the final notification of that type is delayed after winning the bonus. Even if it is executed, it will not be bored by enjoying the game in the process of guessing the bonus type, conversely, it will be convinced that either bonus will be won, and the bonus winning will be done after any bonus flag is established The game process up to is not delayed and does not fall into a monotonous game.
In particular, the variable notification means may be configured to make a determination notification by lottering the winning combination type of the special winning combination or the specific winning combination with a predetermined notification lottery probability in the game in the internal winning state. By varying the lottery probability according to the internal winning state of the special winning combination or the specific winning combination, it is possible to vary the time when the BB or RB winning confirmation notification is executed. Therefore, for example, at the time of BB winning, the notification lottery probability is made smaller than that at the time of RB winning, a game period that is relatively longer than that at the time of RB winning is set to a non-notifying state, and BB winning is predicted from the postponement status of bonus winnings. A game that contributes to an increase in interest can be introduced into the internal winning state by causing a predicted game period to appear. Of course, at the time of RB winning, the notification lottery probability may be made smaller than that at the time of BB winning, and a game period that is comparatively longer than that at the time of BB winning may be set to the confirmed non-notifying state. When performing the BB / RB informing lottery in each game, the upper limit of the informing lottery probability is 1/3 in order to secure a predetermined predicted game period, and the difference in setting of the informing lottery probability is BB It is preferable to make it at least 1.5 times greater at the time of winning and at the time of RB winning.
The adjustment of the rate of play of the number of games of the variable winning opportunity extension means and the variable rate of the fixed notification in the variable notification means is related to each other, for example, according to the winning type (BB and RB) or individually. Can be done. For example, when the adjustment is performed with the lottery probability, when the internal winning is BB, the lottery probability with a high drawing rate by the variable winning opportunity extending means is selected as compared with the case of RB, and the variable notification means It is possible to increase the feeling of expectation for BB by lowering the lottery probability of the confirmation notification in, and extending the period of the bonus-type guessing game. On the contrary, when the internal winning is RB, the total amount of medals cannot be expected to be so large, so the lottery probability with a low extension rate by the variable winning opportunity extension means is selected, and the lottery probability of the definite notification in the variable notification means The bonus game type guessing game period is shortened as much as possible, and it is assumed that the BB win will be lost and the chances of lost the medal (game) will be reduced and the RB winning will be invited early. Good.

In slot machine stop control, pull-in control is performed so that a winning symbol is established by drawing the winning symbol on the winning line within a certain number of symbol frames (for example, four symbols) in accordance with the stop operation timing. However, in the internal winning state, if the bonus symbols with the bonus flag established are pushed and stopped by a stop operation, the bonus winning is achieved. However, in the internal winning state, the small role is won. In such a case, if the bonus symbol cannot be selected due to failure, the winning small combination may be drawn and won.

According to the second aspect of the invention, the variable winning opportunity extending means is re-regarded regardless of the timing of the stop operation when winning a re-game by lottery in the internal winning state of the special winning combination. When the stop mode is controlled so as to establish a game and one of the general winning combinations is won, the stop mode control for establishing the general winning combination is performed according to the timing of the stop operation. In the internal winning state of the specific winning combination, when the re-game is won by lottery, the stop control of the stop mode that establishes the re-game regardless of the timing of the stop operation is performed. In addition, when any of the general winning combinations is won, stop control of the stop mode in which the special winning combination symbol is established according to the timing of the stop operation. Since it is performed prior to the establishment of the winning combination, the player can infer whether the BB or the RB has been won or not from the establishment status of the winning general winning combination. By generating the bonus winning type, the game process from the establishment of one of the bonus flags to the bonus winning becomes a meaningful game for predicting the bonus type, and the entertainment can be further enhanced.

According to the third aspect of the present invention, the variable winning opportunity extending means has a replay (replay) lottery probability in the internal winning state until the special game or the specific game is won. Including a re-gaming high probability state setting means for setting a re-gaming high probability state for performing a lottery based on a lottery probability higher than at the time of the game, and the re-game lottery probability in the re-gaming high probability state is the special winning combination or the Since it was made different according to the internal winning state of the specific winning combination, the player can infer whether BB or RB was won from the replay occurrence state in the internal winning state, even if replay occurs frequently. However, without being bored, it will be convinced that one of the bonuses will be won, and the game process from the establishment of one of the bonus flags to the bonus winning will be replayed. Without becoming monotonous game without slow, it is possible to improve the interest. BB and RB generated in the slot machine according to the present invention are not limited to a single one, and a plurality of types may be provided.
In order to cause an obvious difference in the replay occurrence status in the internal winning state, it is preferable to set the setting difference of the replay probability by the replay high probability state setting means at least 1.5 times.

These components are housed in a display unit case (not shown), and are mounted on the upper part of the front door as a display unit from the back side. Of course, the effect display device can be composed of a liquid crystal or the like having a single display screen.

Although not shown, a polarizing panel is also provided between the liquid crystal display device 15a and the liquid crystal display device 15b to prevent image quality reduction such as color unevenness and moire fringes. The rear liquid crystal display device 15b does not necessarily have to be a transmission type, and the display device is not limited to a liquid crystal, and for example, a color EL (electroluminescence) may be used. In particular, the front display screen may be constituted by a transmissive color liquid crystal display device, and the rear display screen may be constituted by a color EL or a color plasma display device. As the symbol used for the effect display, numbers such as 1, 2, and 3, letters such as alphabets, character designs, and the like can be used.

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) 106a and 106b for effect display and variable display. The VDPs 106a and 106b 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 15a and 15b, respectively.

Connected to the VDPs 106a and 106b are image control ROMs 106c and 106g, character ROMs 106d and 106h for storing image data, VRAMs 106e and 106i as buffer memories for storing image data, and color palette RAMs 106f and 106j, respectively. . The character ROMs 106d and 106h store various types of display image data such as effect pattern image data, background image data, and effect image data. The display image data consists of data designating the color of each dot with a color number. The color palette RAMs 106f and 106j store color data for each color number. The VRAMs 106e and 106i 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 106a and 106b receive various image data from the character ROMs 106d and 106h such as effect symbol image data, background image data, and effect image data from the character ROMs 106d and 106h in response to an image display command (control command) supplied from the CPU 327. 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 106e and 106i, and an image is displayed by supplying these image signals (image frames) to the liquid crystal display devices 15a and 15b 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 106a, 106b receives one control command from the CPU 327. In the display processing procedure, first, data to be displayed is specified from the data stored in the VRAMs 106e and 106i based on the input control command, and the image creation area is set based on the specified data. Display data stored in the character ROMs 106d and 106h are arranged in the respective areas constituting the area. Next, scanning lines are taken out one by one from the image creation areas of the display data individually arranged in the respective liquid crystal display devices 15a and 15b, and the color numbers of the display data constituting the taken-out scanning lines are set to the color palette RAM 106f, The image data is converted into an image signal using the data 106j. The above processing is executed for all scanning lines, and the VDPs 106a and 106b output image signals to the liquid crystal display devices 15a and 15b.

As shown in FIG. 4, the liquid crystal display devices 15 a and 15 b constitute a multiplexed video screen in which the display screens are stacked, and the driver circuit 330 performs a multiplexed video display process 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 15a and the rear display screen of the liquid crystal display device 15b. 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 liquid crystal display devices 15a and 15b are also used independently. For example, the effect display is mainly performed on the front display screen, and the background image is displayed on the rear display screen at that time. 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.

In the slot machine A according to the present embodiment, the sub-control unit 302, the driver circuit 330, and the effect display device 203 determine the winning combination type (BB or RB) of the special winning combination (BB) or the specific winning combination (RB) as a predetermined value. An informing means for making a lottery with a notice lottery probability and confirming the notice is configured. Based on the lottery result, the effect display device 203 performs a winning announcement effect display such as a bonus combination, a small combination, and a replay combination, and a pseudo effect display for notifying the possibility of winning combination.

  The main control unit 301 drives and controls 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. The display 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 includes a reel driving stepping motor. The reel driving units 324a to 324c rotate the reels according to the operation of the start switch, and display predetermined symbols on the reels according to the operation of the stop switch. The stepping motor is driven and controlled so as to stop in the state displayed on the screen. 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, a congratulation display when a winning combination is established, a progress display during a bonus, etc. performed at the time of reel start, reel rotation, or reel stop.

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 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, receives signals from the first sub-control unit 302, and controls speakers and lamps. It has a function to perform. The second sub-control unit 303 includes a CPU 331, 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, and an effect lamp 335 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 game control operation of the slot machine A will be described below. FIG. 6 is a flowchart showing a normal game process by the main control unit during a normal game. First, in order to start a game, a betting number setting process (step S1) 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-game is established by the previous game, the betting number setting process is not performed because the betting number is automatically set. 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 S1), the operation of the start switch 211 is awaited (step S2). When the start switch 211 is operated, a lottery process (step S3) and a reel rotation process (step S4) 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. The lottery table used in this lottery varies depending on the value stored 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 replay that allows the next game to be executed without inserting a new game medium, and a small number of games from the next game. A bonus combination for starting a bonus game that raises the winning probability of a combination, and a miss are included. When a bonus is won, a winning bonus flag of either BB or RB is stored in the RAM of the main control unit. 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”. Hereinafter, processing by the main control unit and the sub control unit will be referred to as main processing and sub processing, respectively.
FIG. 16 shows the details of the lottery process (step S3). A random number is acquired in response to the operation execution of the start switch 211 (step S40), and a winning combination is determined based on the acquired random number (step S41). A bonus flag is stored in the RAM when a bonus is won, and is invalidated when the player is in an internal winning state (steps S43 and S44). Similarly, when any small combination or replay is won, each flag is stored, and in the case of a loss, these combination flags are not established (steps S45 to S48).

  The reel rotation process in step S4 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 S5, it is detected whether or not the stop switch 12 has been operated. And when stop operation is performed, the stop control process (step S6) 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 on the basis of the stop operation position where each reel is stopped and the lottery result of the lottery process. This is done by stopping the rotation. The reel stop position is determined so as to be pulled in and stopped within a predetermined number of symbols, in this case within 4 frames, as viewed from the stop operation position. Then, when there are symbols corresponding to the lottery result within 4 frames from the stop operation position, stop control is performed so that the winning combination symbols are aligned on the active line. In particular, in the re-game stop control process, as will be described later, when the re-game is won not only in the normal game but also in the bonus flag carry-over state, the re-game is always aligned on the active line. Thus, preferential pull-in control is performed.

  Next, in step S7, it is determined whether or not all the reels 206a to 206c are stopped. If not stopped, the process returns to step S5 to perform stop control processing. If all the reels are stopped (step S7), it is determined in step S8 whether or not the winning symbol is on the active line. When a winning is established (step S8) and the winning combination is a small combination (step S9), the payout device 337 is driven to pay out a predetermined number of medals (step S10). On the other hand, when a re-game is established (step S11), an automatic bet number setting process for automatically resetting the bet number set in the current game as the bet number of the next game is performed in step S12. . 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 (step S13).

If the determination in step S8 is NO (non-winning), it is determined in step S14 that a bonus has been won in the lottery, but as a result of stop control, the winning line has not been drawn because it has not been drawn. In this case, a bonus flag carry-over process is performed in step S15. 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 a bonus combination is won.

As shown in FIG. 8, the bonus types include two types of BB and RB. Depending on the combination of the bonus symbols MB1 and MB2 shown in FIG. 3, bonus games having different maximum payout numbers that can be acquired in the bonus game are awarded. When three bonus symbols MB1 or MB2 are arranged, a big bonus BB and a regular bonus RB with a number of medals obtained less than one third of the BB are obtained. In BB and RB, a maximum of 401 sheets and 102 sheets are paid out, respectively. Each bonus is determined by lottery, and a separate bonus flag is established at the time of winning. In addition to bonuses and replay RP, there is a bell role (role type # 4), a watermelon role (role type # 5) and a cherry role (role type # 6-10) fruit roles FR1 to FR7. is there. Among the cherry roles, the role type # 10 is a so-called single cherry role that wins only by stopping on the effective line of the left reel 206a. The watermelon combination (combination type # 5) serves as an operation trigger for operating a replay time RT described later by winning (not only winning but also only when winning).

FIG. 9 shows an example of the lottery table at the setting stage 4 stored in the lottery table storage unit 311. The winning probabilities for BB and RB are 1/270 and 1/410, respectively. In each setting, the combined probability of BB and RB is different by about 5%, and the probabilities of small roles other than the bonus lottery probability are substantially the same. The combination lottery probability table of FIG. 9 shows the set probability values of the internal game state, the bonus game state, and the replay time RT state before the bonus winning occurs, in which the normal game state and the bonus flag are established.

In the normal game state and the internal winning state, the lottery probabilities of the small roles other than the replay RP are the same. In slot machine A, in the internal winning state of BB or RB, until the respective bonus winning occurs, the re-game high probability state in which the lottery probability of re-game is higher than the normal game state. Is set. As shown in the lower part of FIG. 9, the replay high probability state setting means in the internal winning state stores different replay lottery probabilities depending on the internal winning bonus type, from a common replay high probability table for each setting stage. Become. In other words, the RP lottery probability in the normal gaming state is 1 / 7.3, but increases to 1 / 1.5 at the time of BB internal winning, and at the time of RB winning is lower than at the time of BB winning but higher than at the time of normal gaming. Set to 1 / 4.7. Therefore, in the BB internal winning state, the occurrence frequency of replays is higher than in the RB internal winning state, so the player guesses from the replay occurrence state in the internal winning state whether BB or RB has been won. be able to. By increasing the replay occurrence frequency in the internal winning state, the lost lottery frequency is reduced, but if replay occurs frequently, the game period until the bonus winning will become longer and extended, so the replay occurrence frequency differs between BB and RB. Therefore, even if replay occurs frequently, it does not become boring, but conversely, it will be convinced that one of the bonus winnings, and the game process from the establishment of one of the bonus flags to the bonus winning becomes a monotonous game Without a doubt, it contributes to raising interest. At the time of RB winning, it is lower than at the time of BB winning, but conversely, at the time of BB winning, it may be lower than at the time of RB winning. In addition, it is preferable that the RP probability in the replay high probability table in FIG. 9 is at least twice as high as that in the normal game. Further, as in the RB of the present embodiment, the lower setting may be higher than that in the normal game, but may be similar to that in the normal game, and the difference between the higher setting and the higher setting is larger. The discrimination of the bonus flag becomes clear.

In bonus games, by changing the random number range corresponding to a small role and switching to the role lottery table in the bonus game state, which greatly improves the winning probability of the small role, the small role is frequently won and played. It is in an advantageous state where a person can quickly acquire medals. In other words, in the bonus game state, the lottery probability of FR4, FR5, and FR6 among the fruit roles is greatly improved from 1/1000 to 1 / 2.4 in the normal game, and it becomes easier to win during the bonus game. ing.

Next, bonus game processing will be described with reference to FIG. Since the process from step S20 to step S26 is the same as the process from step S1 to step S6 of FIG. 6, description thereof is omitted here. In response to the reel start operation, a lottery based on a role lottery probability table (see FIG. 9) in the bonus game state is performed. If the determination of whether all the reels are stopped (step S26) is YES, it is determined in step S27 whether a winning according to the lottery has been established on the active line. If there is no winning combination, the process returns to step S20 to play the next game. If there is a win, the winning combination is determined in step S28. If the game is replayed, an automatic betting number setting process is performed in step S30 and the process returns to step S20 to play the next game. In the case of a small role, after the payout device 337 is driven in step S29 to pay out a corresponding number of medals, it is determined in step S31 whether or not the bonus game is terminated. The end timing of this bonus game is that the added value of the number of payouts here reaches a certain number, for example, 401 if it is BB. For this reason, every time a small combination 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. After the end of BB or RB, a predetermined number of games (BB is 100 times and RB is 50 times) are replayed RT, and then the normal game is returned.

The RT game is a high-probability re-gaming state in which the probability of winning a re-game is greatly increased by switching the random number width of the lottery table. As shown in FIG. 9, the replay probability is set to 1 / 7.3 in the normal game state, but is significantly improved to 1 / 1.2 in the RT game. In this case, the probability of bonuses and small roles other than replaying is the same as in normal gaming, but since the random number assigned to the outlier is assigned to replaying, replaying is highly probable during RT games. Can be expected to win the bonus when the medal consumption is low. As described above, the RT game continuation count is set to 100 times or 50 times according to BB or RB. 30 RT games are generated not only after the bonus game is over, but also on the condition that the watermelon small role wins during the normal game. Since the bonus flag has already been established, the RP probability in the internal winning state is set to a value (= 1 / 1.5) smaller than the RT state. This is because if the RP probability in the RT state (= 1 / 1.2) is improved, replay will be prioritized too much, and the period until the bonus winnings will be extended by aligning the bonus symbols will be prolonged.

As described above, in the present embodiment, as shown in FIG. 9, the role lottery table is switched according to the normal gaming state, the internal winning state, and the RT state. FIG. 10 shows a distribution pattern of random number lottery determination processing based on the role lottery table in each state. In step S50, the main control unit switches the lottery table used for the random number lottery according to the bonus flag stored in the RAM and its type. When the BB or RB flag that stores the BB or RB bonus flag is turned on, it is determined that the internal winning state is set (process S51), and when the BB flag is turned on (process S52), the RP high probability lottery table is turned on and the RB flag is turned on again. In the case of (Step S53), an RP low probability lottery table smaller than the RP probability of the RP high probability lottery table is selected and determined. When it is not in the internal winning state (processing S50), it is determined whether or not it is in the RT state, and when it is in the RT state, the above-mentioned high probability re-game state winning lottery table is selected and determined (processing S54 and processing S55). When neither the internal winning state nor the RT state is used, the lottery table in the normal gaming state is used (processing S56). In the present embodiment, as a variable winning opportunity extending means for extending a bonus winning establishment opportunity, a switching means between an RP high probability lottery table and an RP low probability lottery table is provided. ) Occurs, the bonus symbol pull-in control becomes possible, and the winning opportunity is extended due to the occurrence of RP, and the pulling rate is varied by switching between the RP high probability lottery table and the RP low probability lottery table. . In the case of shifting to the bonus game, the winning lottery table in the bonus game state is used as described above. In the normal gaming state, the lottery random value for bonus is set to be the same as or partly the same as the random number for a small role such as watermelon or cherry, and is drawn at the same time. Therefore, for example, when a cherry tree is won, there is a possibility that any bonus is won simultaneously.

Regardless of whether the game state is an internal winning state or not, when a re-game is won by lottery, in the stop control within 4 reels of reels by the main process, the re-game is performed regardless of the timing of the player's stop operation. % Stop control is performed. On the other hand, when one of the small combinations is won, the winning establishment depends on the timing of the stop operation depending on the symbol arrangement of the selected small combination. In the present embodiment, when a small role winning occurs in the bonus internal winning state, the priority order for drawing in the bonus symbol and the winning small role varies depending on the bonus type of the internal winning according to the stop operation timing of the player. I have to. In other words, in the BB internal winning state, when a small role is won, if the small role symbol is within the drawable range together with the BB symbol for the stop operation timing, and the former can be drawn preferentially, the drawing priority is given. The BB symbol non-priority pulling-in control in which the ranking is assigned and set to the winning small combination is performed. The small role involved in the priority pull-in control includes a symbol in the vicinity of the BB symbol MB1 on the symbol array in the winning combination symbol. In the case where there are a plurality of kinds of small combinations involved in the priority pull-in control, only a specific small combination may be set as the priority pull-in target. In the RB internal winning state, unlike the BB internal winning state, when a small role is won, if the small role symbol is within the pullable range together with the RB symbol due to the stop operation timing, the drawing priority is set to the RB symbol. The RB symbol priority pull-in control assigned and set to MB2 is performed.

FIG. 11 shows the distribution of the reel stop control mode process according to the gaming state by the main process. In the main process, when it is determined that the normal game state, the re-game is established by 100% regardless of the timing of the player's stop operation when the re-game is won by lottery. The control mode is executed (processes S60 and S64). When it is determined that the internal winning state is determined by confirming the establishment of the bonus flag, the reel stop control table in the normal gaming state is switched to the reel stop control table in the internal winning state. Further, from the determination of the flag type, when the BB flag is on, the BB symbol non-priority pull-in control process mode is set (processes S61 and S62). When the RB flag is on, the RB symbol priority pull-in control process mode is set (processes S61 and S63).

In the BB symbol non-priority pull-in control processing mode, as in the normal gaming state, when a re-game is won by lottery, a stop control is performed to establish a re-game with the highest priority regardless of the timing of the stop operation. When winning a small combination, if the winning small combination can be drawn in advance at the timing when the BB symbol can be drawn, pull-in control is performed in which the priority drawing rank is set to the winning small combination.

In the RB symbol priority pull-in control processing mode, as in the normal gaming state, when replaying is won by lottery, stop control is performed to establish replay with the highest priority regardless of the timing of the stop operation. When winning a winning combination, even if the winning small combination can be drawn in advance at the timing when the RB symbol can be drawn, pull-in control is performed in which the priority pull-in order is set to the RB symbol. The control processing in the BB symbol non-priority pull-in control processing mode and the RB symbol priority pull-in control processing mode constitutes the priority stop control means according to the present invention, and a bonus symbol is generated in the main lottery when a disengagement (in some cases a small character) occurs The winning chance is extended by pulling in a small role priority, and the pulling rate is varied by switching between the BB symbol non-priority pull-in control processing mode and the RB symbol priority pull-in control processing mode. The

According to the distribution of the reel stop control mode process described above, in the internal winning state, depending on the type of the internal winning flag, depending on the stop operation timing, the symbol of the winning general winning combination is preferentially drawn and the winning is established, In addition to the replay occurrence status, the player can infer whether BB or RB has been won based on the established general winning combination. In other words, in addition to the occurrence of replay, one of the small roles is likely to occur, leading to the conviction of BB or RB bonus winning, and the game process from the establishment of either bonus flag to the bonus winning It becomes a meaningful game for predicting the bonus type, and the fun can be further enhanced.

In this embodiment, in the internal winning state, the reel stop control mode process allocation (switching the symbol priority pull-in rank) is performed in parallel with the difference in the RP probability depending on the type of the BB or RB flag. However, it may be performed independently of the switching of the RP probability.

In the present embodiment, as described above, the lottery result is notified using the effect display device 203 or the like, but the bonus type predicted game period based on the RP probability and reel stop control in the internal winning state is played. In order to provide it smoothly to the user, it is necessary to secure a certain amount of the predicted game period. Therefore, it is preferable to reduce the frequency of notification of the type immediately after the bonus flag is established.

FIG. 12 shows bonus winning notification processing by the sub-control unit.
When a main lottery in the main control unit 301 wins a combination play such as a bonus, the first sub control unit 302 performs a sub lottery on whether or not to perform the notification effect of the winning combination. The notification effect is performed by display of the effect display device 203, light emission of various lamps, sound effects, and the like under the control of the first sub-control unit 302 and / or the second sub-control unit 303. The main part of the bonus winning notification by the sub-process will be described below. The sub lottery notification lottery probability table is stored in the ROM 328 of the first sub control unit 302.

The bonus winning notification process is performed in accordance with execution of the main lottery in the main control unit 301. If it is determined on the sub side that the bonus flag is established from communication with the main control unit 301, the process proceeds to a notification process in the internal winning state (steps S70 and S71). If the winning bonus type has already been notified, it is determined that the notification has been completed, and the process ends (step S72). If it is not in the notification completion state, it is determined whether or not only the bonus winning is notified (step S73). When only the bonus winning is notified, the process proceeds to the bonus type notifying process in steps S73 to S89. In the case where only the bonus winning notification is not performed, a lottery (lottery probability: 1 / 1.5) is performed to determine whether or not to perform bonus confirmation notification (step S82). When the lottery is won, a bonus winning decision is notified and the next game and subsequent notification processing is performed (step S84).

FIG. 13 shows one display mode of the bonus winning notification by the effect display device 203. This display mode uses a so-called card turning mini-game effect. In the internal winning state, when all the reels are stopped and in a standby state before starting the reels next time, when a medal is inserted or a bet operation is performed, the mini game effect of FIG. 13 is started. The stop switches 212a to 212c are not used for the stop operation when the reel is not started, but are used for the game when the mini game effect starts. In the start screen (13A), the user is prompted to select one of the three types of cards C1 to C3 by pressing any of the left, middle, and right stop switches 212a to 212c.

When a stop switch is selected and pressed, the display moves to an enlarged display in which the card corresponding to the press switch is turned over, and a display indicating whether or not it is true is performed on the back side. (13C) of FIG. 13 shows an example of a flip screen that means the bonus winning confirmation. In addition to “Ace” shown in the figure, “King (K)” and “Queen (Q)” appear on the winning screen (13C), and “Win” notification is performed. In the internal winning state, not only the bonus confirmation notification but also the notification with high possibility may be performed. For example, a display such as “A bonus has arrived” or “89% confirmed” is displayed on the screen.

Even in a normal gaming state, the possibility of winning a bonus is notified as a so-called pseudo-realistic effect. (13D) in FIG. 13 is an example of the screen when it is out of place, and a number card other than “Ace”, “King (K)”, and “Queen (Q)”, and a message card such as “Sorry” appear. An “out of contact” notification is made.

When the bonus confirmation notification is made, the confirmation notification may be displayed simply by turning over without depending on the selection and pressing of the stop switch. Further, the card may not be displayed unless the card corresponding to the confirmation display (“ACE”) shown in (13C) is actually selected. In this case, as shown in (13B), the second and subsequent choices (in the case of illustration, card C2 is excluded from selection and changed to two choices) are reduced according to the selection mistake, and an appropriateness is assigned. Thus, a notification effect that spans multiple times may be performed.

In the case of the confirmation notification, the reverse display of (13D) shown in (14A) and (14B) of FIG. That is, once the (13D) off-line display appears, a chance screen (14A) that can be selected again appears, and the screen is switched to the 2-option screen (14B). Regardless of which is selected on this 2-choice screen, the winning screen as shown in (13C) is transferred to confirm notification. For example, if C1 is selected on the 2-option screen, “King” is displayed, and if C3 is selected, “Queen” is displayed. (13A) When the other selection screen appears, the player does not perform the selection operation, and when the reel start operation is performed to move to the next game, or when the game is left for 15 seconds, automatic display is performed. Switching lottery (pseudo lottery probability in normal game is 1/12, lottery probability in internal winning state is 1/6) is performed, and when winning, either one is automatically selected as shown in (14C) of FIG. The card is flipped, a “?” Is displayed, and the screen display disappears when the card is not selected. For example, as shown in (14D), a bonus winning confirmation notification is performed by performing a one-round display with a C3 only card as a selection target, as shown in (14D). Note that, after the bonus flag is established, when the bonus winning is not established, reel stop control for causing a specific stop-out pattern called a reach eye to appear is executed under the control of the main control unit 301. Therefore, before receiving the winning notification, the player may be aware of the bonus flag from the reach that appears accidentally when the reel stop operation is performed without being aware of the bonus winning.

In the lottery for determining whether or not to perform bonus confirmation (step S82), the lottery for determining the type of notification for determining the type of winning bonus (lottery probability: 1/128) is also performed (step S85). When this is won, the winning bonus type (BB / RB) is notified, the bonus type notifying completion flag is stored, and the process ends (steps S86 and S81). When the notice lottery (steps S82 and S85) is not won, the process returns to step S70.

When only the bonus winning is notified (step S73), a bonus type notification lottery is performed. The bonus type notification lottery is performed based on the notification lottery probability table in the ROM 328, which differs depending on the type of the internal winning flag (step S74). That is, the type notification lottery when the BB flag is established is performed with a probability of 1 / 7.6 (step S75), and the type notification lottery when the RB flag is established is performed with a probability of 1 / 3.4 higher than that when the BB flag is established. (Step S78). When the bonus type notification lottery is won, the BB or RB type determination notification is performed by the effect display device 203 or the like (steps S77 and S80), the bonus type notification completion flag is stored, and the process ends (step S81). When the type notification lottery (steps S82 and S85) is not won, the process returns to step S70.
Since the notice lottery is performed in each game, it is necessary to secure several games (three times or more) of the predicted game period of the predetermined bonus type. However, if the notice lottery probability is too large, the type notice will be made early and the interest will be made. This may cause a risk of scraping. Therefore, it is preferable that the upper limit of the notification lottery probability is at least 1/3, and the setting difference of the notification lottery probability is set to at least 1.5 times between BB winning and RB winning. As described above, in the present embodiment, the type notification lottery probability P1 when the BB flag is established is 1 / 7.6 (<1/3), and the type notification lottery probability P2 when the RB flag is established is 1 / 3.4. (<1/3) is set to P2 = 2.2P1 (> 1.5P1), and a significant predicted game period based on the difference between the RP probability and the pull-in priority order can be induced.

FIG. 15 shows an example of a bonus type confirmation notification screen. As shown in (15A) of FIG. 15 and the like, since the bonus confirmation notification has already been made, a confirmation mark P is displayed on the upper left of the subsequent screen. (15A) of FIG. 15 shows an example of an effect screen of type notification. In the screen, a ball symbol indicating BB or RB winning falls and accumulates, and the type with the larger number of accumulated balls becomes the definite type. In the case of (15A), since the number of balls of RB is large, a regular bonus confirmation display (15B) is finally performed. (15C) to (15F) show examples of reversal effects from RB to BB. In the case of (15C), since the number of RB balls is large, a regular bonus confirmation display is finally obtained, and a display in which the lucky balls C4 are mixed in the accumulated balls is made. After the completion of the deposition, a part or all of the lucky ball C4 explodes, and a change display (15D) of the RB ball to the BB is performed. As a result, the number of BB balls finally increases (15E), and a big bonus confirmation display (15F) is performed.

As described above, in the game in the internal winning state, since the bonus type notification lottery probability is made different according to the type of the internal winning flag, the time when the BB or RB winning confirmation notification is executed can be made different. . Therefore, for example, at the time of BB internal winning, the notification lottery probability is made smaller than that at the time of RB winning, and a game period that is relatively longer than at the time of RB internal winning is set to a definite non-notifying state, and as described above, replay and / or small role The prediction game period for predicting the BB win from the established situation appears moderately, amplifying the expectation of the BB win in the internal win state, and contributing to an increase in the interest of the slot game. The bonus confirmation notifying process comprises variable notifying means for making variable the number of games after notifying the occurrence of the internal winning state until notifying the winning type of BB or RB in the internal winning state. The variable rate is adjusted by selecting and switching the notification lottery probability based on the notification lottery probability table.
