Description

  The present invention relates to a slot machine, a pachinko gaming machine, and other gaming machines each including a variable display device for variably displaying a plurality of symbols required for a game, and control means such as a microcomputer for controlling the variable display of the variable display device. About.

  For example, a gaming machine called a slot machine or a pachislot is a variable display device mechanically configured by arranging a plurality of rotating reels representing a plurality of symbols in a front display window, or displaying a symbol on a reel on a screen. The variable display device is electrically configured to be displayed on the display device, and in response to the start operation of the player, the control means drives the variable display device to rotate each reel, and automatically or after a predetermined time Paying out game media such as coins when the reels are stopped in sequence by a stop operation and the symbols of the reels appearing in the display window have a specific combination (winning symbol) when the reels are sequentially stopped. However, in the current mainstream models, when the spinning reel stops, the winning symbols are aligned on the active line of the display unit because of the internal processing of the gaming machine. To If you Tsu is (specifically, when was elected in the lottery by the random number extraction with micro-computer). This is because if the symbol at the time of stop is determined only by the stop operation (timing) of the player, the result of the game (win or loss) is determined by the skill of the player, and only the skill of the player is emphasized, and the soundness of the game is enhanced. This is to solve the problem that the management of the coin payout rate and the like from the gaming machine becomes difficult for the gaming machine as well as the game machine is damaged.

  Therefore, even if the player can stop the game (for example, a slot machine provided with a stop button), if the player does not win the winning, no matter how the player performs the stopping operation, the winning symbol is displayed as an effective line. It cannot be aligned on top. That is, the gaming machine is such that the skill of the player is unlikely to appear in the result of the game.

  However, the above-mentioned gaming machine has a problem that the higher the level of skill of the player, the less the skill is reflected in the game result, and the more attractive the game is.

  Therefore, a gaming machine has been developed which can obtain a game result according to a player's stop operation under certain conditions. One example is disclosed in Japanese Patent Publication No. 5-74391. In a slot machine as described above (including a so-called pachislot machine), when a specific condition is achieved during a game, stop control by random number lottery is performed for a predetermined number of games for a part or all of a plurality of reels. During the suspension period (hereinafter referred to as “challenge time”, abbreviated as “CT”) during the suspension period, the display mode when the reels are stopped at the timing of the player's stop operation (design) ) Is determined, so that the skill of the player is reflected in the game result, and except for the CT period, the stop control is performed by the random number lottery as before, so that even a player with poor skill can win a certain amount of prizes. Secured. As a result, the slot machine has become a gaming machine that balances gaming characteristics and equality. Hereinafter, the game during the “CT” period is referred to as “CT game”.

  More specifically, “CT” is a period during which variable symbols can be aligned when variable display is stopped in response to a player's stop operation, regardless of whether a random number lottery or the like is determined. In addition, during the “CT” period, the small prize that the player can easily obtain is not determined, and the large prize that the player is hard to obtain, for example, a special prize (BB) and a special prize (RB) described later. There is also a method for making the judgment. This “CT” starts when a predetermined generation condition is satisfied and ends when a predetermined release condition is satisfied.

  However, even when the above-described gaming machine is provided with “CT”, a player, particularly a beginner, does not clearly recognize CT, or even if he does, ends “CT gaming” without taking advantage of the advantage. It is easy to do it.

  In addition, as one of the restrictions on gaming machines, there is an upper limit to the profit that a player can obtain in one game, that is, the number of game media, so that a skilled person can obtain much profit as soon as CT starts. Then, the end of the CT becomes closer, and if the early end of the CT is repeated, the user loses interest in the CT.

  Therefore, an object of the present invention is to provide a gaming machine that enables even an unskilled person to clearly recognize a CT and play a game, and also allows a skilled person to fully enjoy a CT game.

  The present invention provides a variable display means for variably displaying a plurality of symbols necessary for a game, and a stop control of the variable display of the variable display means based on a player's operation and a random number lottery result. When the display mode at the time of performing is a specific symbol combination, in the gaming machine provided with control means for performing a specific game, the specific game is in a gaming state in which a symbol combination of winning for a predetermined period is easily established. The game includes a game and a combination game of the BB game and a CT game in which stop control based on the random number lottery is stopped for a predetermined winning combination, wherein the control means is used for determination of random number sampling, and a winning area is predetermined. It is determined whether or not the sampled random number belongs to the winning area of the combination game of the BB game and the CT game in the winning probability table, and a result of the determination Based on, characterized by stop control variable display of said variable display means.

  An embodiment of the present invention is characterized in that the winning probability table is determined so that a winning area of the BB game and a winning area of a combination game of the BB game and the CT game are different.

  In another embodiment of the present invention, the control means is configured such that the display mode of the variable display controlled to be stopped based on the result of the determination is a specific symbol combination different from the symbol combination for generating the BB game. In this case, a combination game of the BB game and the CT game is generated.

  According to the present invention, during the game, the control means determines the mode to be displayed when the variable display of the variable display device is stopped by random number lottery, and controls the variable display to stop based on the determination. Then, when the display mode when the variable display is stopped is a specific symbol combination, a state in which a BB game as a specific game advantageous to the player or a combination game of the BB game and a CT game can be performed. When the winning symbol corresponding to each type of the specific game is stopped and displayed, the control means starts the specific game corresponding to the winning symbol.

  Therefore, the player can perform a BB game or a combination game of the BB game and the CT game in which a winning combination of symbols is easily established for a predetermined period, and a great profit can be obtained by these games. In particular, in the latter combination game, a desired winning symbol can be aligned at the time of stopping the variable display by performing a stop operation such as pressing a stop button with good timing during the CT period, so that the player's skill can be improved. It will be reflected in the result.

  FIG. 1 is a perspective view showing an appearance of a slot machine according to one embodiment of the present invention. The slot machine 1 is a gaming machine that plays a game using a coin, a medal, or a token as a game medium. In the following, a description will be given assuming that a medal is used.

  A start lever 5 for rotating the reel by a player's operation is attached to the lower left side of the display window on the front of the cabinet 2 so as to be rotatable within a predetermined angle range.

  On the lower right side of the display window 3R, a medal insertion slot 6 for inserting a medal of a game medium is provided. Above the medal insertion slot 6, a credit display section 7A for displaying the number of currently credited medals is paid out. A payout display section 7B for displaying the number of medals is provided. Each display is composed of 7 segment LEDs. The display means is not limited to an LED, but may be an LCD (liquid crystal) element or any other means.

  On the lower left side of the display window 3L, there are provided an insertion button 17 for inserting credited medals for a game and a C / P switch 8 for switching the credit / payout of medals obtained by the player by a push button operation. I have.

  Stop buttons 9L, 9C, 9R operated by the player to stop the rotation of each reel are arranged alongside the start lever 5. Each stop button has a built-in light source or is configured to emit light when irradiated with light. Therefore, the stop buttons 9L, 9C, 9R become brighter or darker depending on whether each light source is turned on, blinked, or turned off. The stop buttons 9L, 9C, 9R are turned on by the corresponding light sources 9L ', 9C', 9R ', and are used as notification means in this gaming machine.

  A medal payout opening 12 and a medal receiving unit 13 for storing paid-out medals are arranged in a lower front part of the cabinet 2. A sound generator 10 is provided at the lower right of the medal payout opening 12. Sound is output from a speaker 15 (FIG. 2) arranged inside the cabinet 2 through the sound generator 10. The speaker 15 can output a plurality of types of sounds, and is used as a notification unit in the gaming machine.

  Above the display window on the front of the cabinet, there is provided a display surface 16 on which a payout table indicating how many medals will be paid out for winning is displayed, and an upper edge thereof is formed as a light emitting effect portion 11. Have been. The effect section 11 is composed of a large number of LEDs, and can perform various effects and display information by operations such as lighting, blinking, and turning off. The operation of the effect section 11 is also used as a notification means in the gaming machine.

  FIG. 2 shows a circuit configuration including a control unit for controlling a game processing operation in the slot machine 1 and a peripheral device (actuator) electrically connected to the control unit.

  In this case, the control means includes the microcomputer 20 as a main component, and further includes a circuit for random number sampling. The microcomputer 20 includes a CPU 21 for performing a control operation according to a preset program, a ROM 22 and a RAM 23 as storage means, and the CPU 21 has a clock pulse generating circuit 24 and a frequency divider 25 for generating a reference clock pulse, A random number generator 26 for generating a random number to be generated and a random number sampling circuit 27 are connected. As means for random number sampling, random number sampling may be performed in the microcomputer 20, that is, on the operation program of the CPU 21. In this case, the random number generator 26 and the random number sampling circuit 27 can be omitted, or can be left as a backup for the random number sampling operation.

  The ROM 22 of the microcomputer 20 stores data for winning determination including a winning probability table, which is used for determining random number sampling performed each time the start lever 5 is operated.

  The ROM 22 further includes data for generating a plurality of types of sounds, data for determining a sound to be generated based on a stop symbol when the reels are stopped, and a notification device for generating information according to the state of a CT game to a player. Data for determining a sound to be played is stored.

  In the circuit of FIG. 2, the main actuators whose operations are controlled by control signals from the microcomputer 20 include stepping motors 14L, 14C, 14R for driving the reels 4L, 4C, 4R to rotate, and medals of game media. (Including a drive unit for paying out) 30, display units 7A and 7B, stop buttons 9L, 9C and 9R, a light source of staging unit 11, and speaker 15, and motor drive circuit 31, hopper The driving circuit 32, the light source driving circuit 37, and the sound output circuit are connected to the output unit of the CPU 21. Each of these drive circuits receives a control signal such as a drive command output from the CPU 21 and controls the operation of each actuator.

  The main input signal generating means for generating an input signal necessary for the microcomputer 20 to generate a control signal includes a medal inserted in the medal insertion slot 6 or a credit input by pressing the input button 17. Each sensor receives a pulse signal from a medal sensor 6S for detecting a medal, a start switch 5S for detecting operation of the start lever 5, a C / P switch 8, each stop button 9L, 9C, 9R, and a reel rotation sensor. A medal payout when the count value of the medal detection unit 33 (the number of medals paid out from the hopper 30) reaches the designated number data, the reel position detection circuit 35 supplying a signal for detecting the position of the reel to the CPU 21. There is a payout completion signal circuit 36 that supplies a signal for detecting completion to the CPU 21.

  In the circuit of FIG. 2, the random number generator 26 generates a random number belonging to a predetermined numerical range, and the sampling circuit 27 samples one random number at an appropriate timing after the start lever 5 is operated. It is determined whether the extracted random numbers belong to a predetermined prize area stored in the storage unit in the ROM 22, and a signal based on the determination result is generated.

  After the rotation of the reels 4L, 4C, 4R is started, the number of drive pulses supplied to each of the stepping motors 14L, 14C, 14R is counted, and the counted value is written in a predetermined area of the RAM 23. A reset pulse is obtained from each of the reels 4L, 4C, 4R for each rotation, and these pulses are input to the CPU 21 via the reel position detection circuit 35. The CPU 21 clears the drive pulse count value stored in the RAM 23 to “0” by the reset pulse thus obtained. As a result, the RAM 23 stores the count value corresponding to the rotation position within one rotation of each of the reels 4L, 4C, and 4R.

  The control unit determines the stop position of each of the reels 4L, 4C, 4R based on the signal generated by the determination of the random number, and sends a signal for controlling the reel to stop at that position to the motor drive circuit 31.

  When detecting a stop signal generated by operating the stop buttons 9L, 9C, 9R, the control unit stops the reels 4L, 4C, 4R, respectively.

  The data for winning determination stored in the ROM 22 includes a winning symbol combination table for associating a winning combination of symbols, the number of winning medals, and a winning determination code representing the winning, It is referred to when controlling the respective reels 4L, 4C, 4R and when confirming a winning after stopping all the reels.

  The data for determining the sound generated based on the stop symbol when the reel is stopped stored in the ROM 22 includes a winning symbol combination table and a table for associating the type of sound. With this table, the type of sound is determined by the winning confirmation after stopping all the reels.

  The ROM 22 stores a program (sequence program) for executing a game in the slot machine 1.

  FIG. 3 shows a general game, a special increase prize game (hereinafter, referred to as a BB game), a special prize game (hereinafter, referred to as an RB game), and a challenge time game (hereinafter, a CT game) which are game states performed in the slot machine 1. ).

  In this gaming machine, a general gaming state is established at the start of the game, and random number sampling is performed each time the start lever 5 is operated, and the most advantageous combination of the BB game and the CT game, the combination of the RB game and the CT game, the BB game, A determination is made as to whether any of the RB game, the CT game, and the accessory has been won or lost.

  The winning determination for determining the occurrence of the CT game may be performed each time the general game is played, each time the BB game is generated or terminated, and each time the RB game is generated or terminated.

  The BB game is the most advantageous state for the player generated by the winning symbol "7-7-7", and is a gaming state in which a maximum of 30 consecutive prizes can be obtained and a large number of medals can be obtained. This is the same state as when the RB game has occurred three times. During the BB game, the winning determination of the BB game, the RB game, and the CT game is not performed, and only the winning determination of the accessory is performed. In the slot machine 1, when a winning symbol "7-7-7" is generated, a sound set for the winning symbol "7-7-7" is generated from the speaker 15. By this sound, the player can know that the BB game is started.

  The RB game is a game state that is generated by a stop symbol “BAR-BAR-BAR” and in which a state in which a winning of a character is likely to occur continuously continues up to 12 times. During the RB game, as in the BB game, the winning determination of the BB game, the RB game, and the CT game is not performed, and only the winning determination of the accessory is performed. When a winning symbol “BAR-BAR-BAR” occurs in the slot machine 1, a sound set for the winning symbol “BAR-BAR-BAR” is generated from the speaker 15. This sound also allows the player to know that the RB game is starting.

The combination of the BB game and the CT game, the winning symbol "7 - 7 - 7" (7 refers to the ribbon with 7) generated by, after the end of CT game of the BB game is generated. In the slot machine 1, the winning symbol when "7 - 7 - 7" occurs, the speaker 15, the winning symbol "7 - 7 - 7" setting sounds for occurs. By this sound, the player can know that not only the BB game but also the CT game can be performed.

  In the CT game, a reel is stopped based on a player's stop operation. In the slot machine 1, random number sampling is performed each time the start lever 5 is operated, and a winning determination of the BB game and the RB game is performed. When a prize is won, the control unit performs reel stop control according to the prize. The winning determination of the CT game and the accessory is not performed.

  As shown in FIG. 3, in the slot machine 1, when a BB game, an RB game, or a CT game is won during a general game, each game is started. When the BB game, the RB game, or the CT game ends, the game returns to the normal game. At the time of winning the combination of the BB game or the RB game and the CT game, the game shifts to the CT game when the BB game or the RB game ends. If the BB game is won during the CT game, the CT game is interrupted and the BB game is started. If the RB game is won during the CT game, the CT game is interrupted, the RB game is interrupted, and when the RB game ends, the remaining CT games are restarted.

  The CT game is terminated when the predetermined number of games have been played, 150 times in the slot machine 1. The CT game is ended when a predetermined net number of medals is obtained and in the slot machine 1, 200 net number of medals are obtained.

  When the number of games in the CT game approaches 150 or the number of net additions approaches 200, and the end of the CT game approaches, the stop buttons 9L, 9C, 9R, the staging unit 11, and the speaker, which are notification means of the slot machine 1, 15 notifies the player of the situation. The three stop buttons are brightened or darkened so that the player can operate the stop buttons in an order that is advantageous to the player, and the staging unit 11 displays a display that alerts the player. Then, the speaker 15 generates a special sound.

  Further, since the winning symbols are not aligned and no payout is performed in the CT game, when the number of medals consumed by the player reaches a considerable amount, the number of medals consumed in the slot machine 1 is reduced to the number of medals obtained in the game. When the number exceeds 30, the notification means notifies the player of the situation in which such a disadvantage is occurring.

  FIG. 4 is a symbol row provided on the outer peripheral surface of the reels 4L, 4C, 4R of the slot machine 1.

  The intervals at which the respective symbols of "grape" 40, "JAC" 41 and "persimmon" 42, which are the accessory symbols in the symbol row of the reel 4L, are almost 5 or 6.

  The intervals at which the respective symbols of “grape” 40, “JAC” 41, and “persimmon” 42, which are the accessory symbols in the symbol row on the reel 4C, are 3, 4 or 5.

  The intervals at which the symbols of the "grapes" 40, "JAC" 41 and "persimmons" 42, which are the accessory symbols in the symbol row of the reel 4R, are almost four, and in rare cases are five.

  Since the intervals at which the symbols 40, 41, and 42 appear on the reel 4R are closer and equal on the other two reels, the stop button 9R of the reel 4R is pressed after the reel 4L and the reel 4C stop. When operated, the patterns are easily aligned.

  On the other hand, when the stop button 9L of the reel 4L is operated after the reel 4R and the reel 4C have stopped, even if the symbols of the reel 4R and the reel 4C are aligned, the appearance interval of each symbol of the reel 4L is long. It is difficult to align.

  FIGS. 5, 6, and 7 are flowcharts showing the operation of the control means in the CT game. In this flowchart, the counter N indicates the allowable number of net increases in the number of medals, and the initial value is 200. The counter N is incremented when medals are inserted and decremented when medals are paid out. When the counter N becomes 0, the CT game ends. The counter T indicates the remaining number of games allowed in the CT game, and the initial value is 150. The counter T is decremented by 1 each time the game is performed, and the CT game ends when the counter T becomes 0. I do.

  When the player wins the CT game and enters the CT game state, the staging unit 11 and the stop buttons 9L, 9C, and 9R, which are notification means, display a "situation 1" mode for displaying a normal state of the CT game (step 1). ). The aspect of "situation 1" will be described later.

  When a medal is inserted, a signal is generated from the medal sensor 6S (step 2), and the number of inserted medals 1 to 3 is added to the counter N (step 3).

  The start lever 5 is operated to operate the start switch 5S (step 4). The reels 4L, 4C, 4R are rotated (step 5). The counter T is decremented by 1 (step 6).

  A random number is extracted and a determination process is performed (step 7).

  It is determined whether the stop button operation has been performed (step 8), and the reels 4L, 4C, 4R are stopped (step 9).

  The winning of the stopped symbol is determined, and the payout of the medal is executed (step 10). The counter N is subtracted by the number of paid medals (step 11).

  Next, it is determined whether or not the release condition of the CT game is satisfied (step 12). The conditions for canceling the CT game are as follows: when the BB game or the RB game is won by the random number determination and the winning symbols “7-7-7” or “BAR-BAR-BAR” are completed, the number of games in the CT game is reduced. When the counter T reaches 150 times and the counter T is 0, and when the net increase in the number of game media during the CT game reaches 200 and the counter N is 0 is set.

  When none of these release conditions is satisfied, that is, when the determination result is “NO”, it is determined whether the counter N is 230 or more (step 13). This determination is a determination as to whether the number of medals consumed for the game has exceeded the number of medals obtained in the game by 30 or more. In the case of “YES”, that is, when the counter N is 230 or more, The display of the unit 11, the display of the stop buttons 9L, 9C, 9R, and the sound from the speaker 15 are set to the "situation 2" in which the disadvantageous state occurs, and the player is notified (step 14). The aspect of “situation 2” will be described later.

  If the determination in step 13 is "NO", it is next determined whether the counter N is 50 or more (step 15). If "YES", that is, if the counter N is 50 or more, it is determined whether the counter T is 10 or more (step 16).

  When the counter T is 9 or less and the remaining number of CT games approaches the end and the determination result is “NO”, the display of the rendering unit 11, the display of the stop buttons 9 L, 9 C, 9 R, and the display from the speaker 15, which are notification means, are provided. The voice is changed to a state of "Situation 3" informing that the number of times that the game can be played is reduced and the CT game is nearing the end (step 17). The aspect of "Situation 3" will be described later.

  On the other hand, in the determination in step 15, when the counter N is 49 or less and the determination result is "NO", the display of the effect unit 11, the display of the stop buttons 9L, 9C, 9R, and the sound from the speaker 15 are notified means. In a state of “situation 4” informing that the net increase number approaches the upper limit and the CT game is nearing the end (step 18). The aspect of "Situation 4" will be described later.

  If the release condition is satisfied in step 12 and it is determined to be "YES", then it is determined whether the release condition is a winning of the BB game (step 19). If "YES" is determined, the BB game is executed (step 20), and after the end, the counter N and the counter T are set to 0 (steps 23, 24 and 25), and the normal game is resumed (step 26). The game is over.

  If “NO” is determined in the determination of Step 19, it is determined whether or not the RB game is won next (Step 21). If "YES" is determined, the RB game is executed (step 22), and after the RB game ends, the process returns to step 2 to resume the CT game. The values of the counter N and the counter T at the time of restarting the CT game are values before the RB game is started.

  If the result of the determination in step 23 is "NO", that is, if neither the BB nor the RB has been won, it is determined whether or not the counter N is 0 (step 23). The value is set to 0 (step 24), the normal game is restarted (step 26), and the CT game is ended. When the determination result of step 24 is "NO", the counter T is always 0, so that the counter N is set to 0 (step 25), and the normal game is restarted (step 26), so that the CT game is ended.

  In the above steps 1, 14, 17 and 18, the notification modes of "status 1", "status 2", "status 3" and "status 4" are set in accordance with the purpose of notification.

  The state of "Situation 1" notifies the player that the game is a CT game, and sets the state different from the general game, the BB game, and the RB game. For example, the flashing state of the effect part 11 is changed, all the stop buttons are flashed, or different sounds are generated.

  The state of “Situation 2” is to inform that the number of medals consumed by the player greatly exceeds the number of medals obtained by winning and that a loss has occurred. Make the difference and draw the player's attention. Further, when the stop button 9R of the reel 4R is operated after the reel 4L and the reel 4C have stopped, the symbols are easily aligned. Therefore, only the stop button 9L is blinked, or the order in which the stop buttons shine is the stop button 9L first, then the stop The operation sequence of the stop button is taught by using the button 9C and finally the stop button 9R. Further, a voice different from the “situation 1” is generated to call attention.

  The mode of “Situation 3” is to notify that the remaining number of times that the CT game can be played is approaching the end, and to make the blinking state of the directing unit 11 different from “Situation 1” or, like “Situation 2”, The order of stop buttons operated in the order in which the stop buttons glow is taught so that the player can achieve a large number of symbol prizes with a limited number of games, or a sound different from "Situation 1" is generated. The state of “Situation 3” may be the same as the state of “Situation 2”, but, for example, the blinking speed of the staging unit 11 is increased, or the blinking speed of the stop button or the changing speed of the stop button is changed. Alternatively, the target information may be notified as a mode different from “Situation 2”, such as generating a different warning sound.

  The state of “Situation 4” indicates that the net increase in the number of medals that can be obtained during the CT game is approaching the upper limit, and the flashing state of the rendering unit 11 is changed to “Situation 1”, “Situation 2”, and “Situation 3”. In order to increase the number of games and increase the chances of winning BB and RB by random number extraction, the operation order of stop buttons that are difficult to win symbols is taught in the order in which the stop buttons glow, 1, "Status 2", and "Status 3". As described above, when the stop button 9L of the reel 4L is operated after the reel 4R and the reel 4C are stopped, even if the symbols of the reel 4R and the reel 4C are aligned, the symbol interval of the reel 4L is far and it is difficult to align the symbols. Therefore, only the stop button 9R is made to blink, or the order in which the stop button shines is set to the stop button 9R, then the stop button 9C, and finally to the stop button 9L to teach the operation order of the stop button.

  Such notification allows the player to know the order in which the stop button is pressed, or to use the reported information to enjoy the CT game advantageously with his or her own ingenuity.

(1) Variable display means for variably displaying a plurality of symbols necessary for a game, and stop control of the variable display of the variable display means based on a random number lottery result to specify a display mode when the variable display is stopped.

When a lottery is performed each time a general game is performed, the winning of the CT game is determined as the winning of the BB game and the RB game when determining the winning of the random value extracted by the random number sampling performed for determining the winning of the general game. The winning combination may be set. In such a combination winning, the CT game is started after the BB game or the RB game ends.

  In an embodiment, when a predetermined situation is reached during the specific game, the notification means notifies the player of the situation. The situation to be notified is, for example, that the CT release condition is satisfied, that is, the end of CT is approaching, the loss of the player exceeds a predetermined amount, and the disconnection continues for a predetermined number of times. By changing the notification content of the notification means, it is possible to notify the player of the situation of the game. By such notification, the player recognizes that the specific game is about to end, that his or her own loss is large, that there is no prize for a while, and that the player devises a stop operation so that the CT game can be continued. It is possible to take measures according to the situation, such as terminating the game so that the loss does not increase further.

  As the notification means, for example, a visual display means such as a liquid crystal, a CRT, an LED, or the like, or a sound generation means for notifying by sound, such as a buzzer or a speaker, is suitably used. In the case of using these notification means, when a predetermined situation is reached, a predetermined notification operation (flashing of a light emitter, generation of a specific sound, etc.) is made to the notification means by a signal from the control means of the gaming machine. , Let the player recognize.

  The notification means may be configured to include not only the above-described visual or audible means but also a notification control unit that drives and controls these means. That is, the notification means may be driven by a CPU provided as a notification control unit separately from the microcomputer of the gaming machine when a predetermined situation is reached.

  In addition, when the notification unit is configured to notify the player of a stop operation (for example, an operation sequence of a plurality of stop buttons corresponding to a plurality of reels), even an unskilled player can perform a CT game. It can be performed advantageously. Further, the notification means may notify that there is a winning to start a BB game, an RB game, or the like as a result of the determination by the internal lottery.

  If the condition for canceling the CT is that the “net increase” obtained by subtracting the number of game media consumed for the game from the number of game media obtained by the player reaches a predetermined number, a notification means is provided. By notifying with, when it is advantageous to increase the number of games, the player can perform a stop operation so as not to become a winning symbol thereafter. Further, if the cancellation condition is that the number of games in the CT period reaches a predetermined number, by notifying it by the notification means, the player can obtain a small profit when increasing the number of game media. It is possible to increase the number of prizes and aim for game media.

  More specifically, the release condition for the CT game to be interrupted or terminated and the control means to resume the variable display stop control is determined as a result of the internal lottery winning determination performed during the CT game, "BB game" Or, when the "RB game" has been won, when the number of games in the CT game has reached a predetermined number, or when the net increase in the number of game media in the CT game has reached a predetermined number, etc. One or a combination of two or more is selected. Among the above-mentioned cancellation conditions, for example, even if the BB game or the RB game is won, the BB game or the RB game is started, and the control means resumes the variable display stop control based on the internal lottery, the BB game or the RB game is started. It is also possible to set to restart the CT game after the operation of is completed. It is also possible to set so that the CT game is not restarted when the BB game ends, and the CT game is restarted when the RB game ends.

  In particular, there are two types of prizes: a special increase prize ("BB" described later) that gives the player a relatively large profit, and a special prize ("RB" (described later)) that gives the player a relatively small profit. In the case where the number of species is three or three ("SB" to be described later is added), when the control means determines the special increase winning (BB) during the CT period, the CT period ends and the player receives the special additional winning (BB). When a special win (RB) is determined during the CT period, the CT period is interrupted, and the player obtains a profit corresponding to the special win (RB) when the special win (RB) is determined during the CT period. After the end of the gaming state, the interrupted CT is restarted. Thereby, the player can enjoy the CT game regardless of the skill.
