Description

  The present invention relates to a gaming machine that variably displays a symbol and gives a privilege according to the symbol stopped and displayed.

  Conventionally, for example, a pachinko gaming machine collectively referred to as a so-called “seven machine”, which has a symbol display window for variably displaying symbols, and generates a jackpot or a bonus according to the combination of symbols stopped and displayed in the symbol display window And gaming machines such as slot machines are known. For example, in a pachinko gaming machine, a jackpot lottery is performed in accordance with the winning of a pachinko ball to a start chucker or a through chucker, and symbol variation is started in the symbol display window. The result of the jackpot lottery is notified by a combination of stop symbols in the symbol display window. If the jackpot lottery is won, for example, a jackpot symbol such as “777” or the like is stopped and displayed in the symbol display window, and then a jackpot is opened, such as an attacker.

  Such pachinko gaming machines called “seven machines” are configured such that, for example, the degree of expectation for jackpots differs depending on the type of reach symbol (reach symbol) that will become a slot in one symbol. There are gaming machines (for example, see Patent Documents 1 and 2). In such a pachinko gaming machine, it is trying to enhance the interest of the game by raising the player's expectation for the jackpot according to the type of reach design.

  Furthermore, as for the pachinko gaming machines collectively referred to as “seven machines” as described above, the symbol variation is temporarily changed about once to several times between the start of the symbol variation and the combination of the stopped symbols. There is a gaming machine that performs a so-called pseudo-continuous production (hereinafter referred to as a continuous production) that looks like it has stopped. For example, if the degree of expectation for jackpot is increased as the number of temporary stops until the combination of the confirmed stop symbols is determined, the effect of the continuous production can be further enhanced.

  In this way, as a technique for enhancing the production effect by continuous production, by reducing the types of symbols that are variably displayed at each temporary stop, it seems that a big hit symbol is likely to occur, a game for jackpot Have been proposed (see, for example, Patent Document 3). In addition, a method has been proposed that increases the player's expectation of jackpots by increasing the number of jackpot symbols out of a predetermined number of symbols that are variably displayed each time a temporary stop occurs (for example, patents). Reference 4). Note that a gaming machine such as a slot machine may have the same configuration as described above.

  However, the conventional gaming machine has the following problems. In other words, in gaming machines where the degree of expectation for jackpots differs depending on the type of reach symbol, there is a risk that the game will be less interesting due to falling into one pattern according to the familiarity with the game. In addition, in the gaming machine adopting the above-mentioned continuous production, the greater the number of temporary stops, the higher the expectation for the jackpot, but “Okay, here! It is not clear and the player's attention may be distracted. When a continuous production occurs, the player vaguely thinks that “continue more” and there is no way to deal with it, and there is a possibility that the interest of the game cannot be maintained high over a long period of time.

  The present invention has been made in view of the above-described conventional problems. In a gaming machine that displays a symbol in a variable manner and gives a privilege according to the symbol that is stopped and displayed, the effect of the symbol variation display is enhanced. An object of the present invention is to provide a gaming machine having excellent characteristics capable of maintaining a high interest in gaming over a period of time.

The first invention comprises lottery means for executing lottery processing in response to establishment of a predetermined start condition;
There are a plurality of symbol display areas for variably displaying a plurality of types of symbols associated with different numbers, and the lottery result by the lottery means is determined by a combination of the fixed stop symbols that are stopped and displayed in the symbol display areas. A symbol variation means to be notified;
When the lottery result is a win, the final stop symbol scheduled to be stopped and displayed in each symbol display area is determined so that the combination of the fixed stop symbols becomes the same symbol combination, while the lottery result is lost. Stop symbol determining means for determining a fixed stop symbol scheduled to be stopped and displayed in each symbol display area so that the combination of the fixed stop symbols is not the same type of symbol combination in some cases,
A privilege granting means for granting a privilege to the player when the combination of the fixed stop symbols actually stopped and displayed in the plurality of symbol display areas is a combination of symbols of the same type;
A variation pattern selecting means for selecting any one of a plurality of preset variation patterns each time the symbol variation means starts displaying a variation of a new symbol;
The symbol variation means is configured to perform symbol variation display and stop display according to the variation pattern selected by the variation pattern selection means,
As the variation pattern of one symbol variation from when the symbol variation means starts displaying the variation of a new symbol until when the combination of the fixed stop symbol is stopped and displayed, the symbol variation is started after the new symbol variation is started. The first variation period until the stop symbol or temporary stop symbol is stopped and displayed in each symbol display area, and after the temporary stop when the temporary stop symbol is stopped and displayed, the variable display of the symbol is resumed and then the fixed stop symbol or A plurality of variation patterns having different number of variations, which is the total number of occurrences of the second and subsequent variation periods until the temporary stop symbol is stopped and displayed in each symbol display area, are set.
When the lottery result is a win, the variation pattern selection means determines a variation pattern to which a variation number having a predetermined relationship with the number associated with the fixed stop symbol determined by the stop symbol determination means is assigned to another variation The gaming machine is configured to select with a higher probability than the pattern (claim 1).

The second invention comprises a lottery means for executing a lottery process in response to establishment of a predetermined start condition;
There are a plurality of symbol display areas for variably displaying a plurality of types of symbols associated with different numbers, and the lottery result by the lottery means is determined by a combination of the fixed stop symbols that are stopped and displayed in the symbol display areas. A symbol variation means to be notified;
When the lottery result is a win, the final stop symbol scheduled to be stopped and displayed in each symbol display area is determined so that the combination of the fixed stop symbols becomes the same symbol combination, while the lottery result is lost. Stop symbol determining means for determining a fixed stop symbol scheduled to be stopped and displayed in each symbol display area so that the combination of the fixed stop symbols is not the same type of symbol combination in some cases,
A privilege granting means for granting a privilege to the player when the combination of the fixed stop symbols actually stopped and displayed in the plurality of symbol display areas is a combination of symbols of the same type;
A variation pattern selecting means for selecting any one of a plurality of preset variation patterns each time the symbol variation means starts displaying a variation of a new symbol;
The symbol variation means is configured to perform symbol variation display and stop display according to the variation pattern selected by the variation pattern selection means,
As the variation pattern of one symbol variation from when the symbol variation means starts displaying the variation of a new symbol until when the combination of the fixed stop symbol is stopped and displayed, the symbol variation is started after the new symbol variation is started. The first variation period until the stop symbol or temporary stop symbol is stopped and displayed in each symbol display area, and after the temporary stop when the temporary stop symbol is stopped and displayed, the variable display of the symbol is resumed and then the fixed stop symbol or A plurality of variation patterns having different number of variations, which is the total number of occurrences of the second and subsequent variation periods until the temporary stop symbol is stopped and displayed in each symbol display area, are set.
When the lottery result is a win, the stop symbol determination means has a higher probability of a symbol associated with a number having a predetermined relationship with the number of fluctuations in the fluctuation pattern selected by the fluctuation pattern selection means than other symbols. The game machine is configured to determine the fixed stop symbol as described above (claim 2).

  Here, first, the symbol variation in the first and second inventions, the symbol variation display is started at the same time starting from the state where the fixed stop symbol is stopped in each symbol display area, This corresponds to the period until the fixed stop symbol is again displayed in the symbol display area. Then, in this symbol variation, after the symbol variation display is started or restarted from the state where the fixed stop symbol or the temporary stop symbol is stopped and displayed, either the fixed stop symbol or the temporary stop symbol is displayed. The fluctuation period until the earlier one is stopped and displayed in each symbol display area may occur once or twice or more.

  The gaming machine according to the first and second aspects of the invention selects any one of a plurality of variation patterns having different numbers of variations, which is the total number of occurrences of the first variation period and the second and subsequent variation periods. The variation pattern selection means and the symbol variation means for performing symbol variation or variation stop according to the selected variation pattern. When the lottery result is a win, the variation pattern selection means in the gaming machine according to the first aspect of the invention has a high probability that a variation pattern to which the number of variations having a predetermined relationship with the number associated with the stop symbol is assigned. select. On the other hand, when the lottery result is a win, the stop symbol determination means in the gaming machine of the second invention associates the number of fluctuations in the fluctuation pattern selected by the fluctuation pattern selection means with the number having the predetermined relationship. The determined symbol is determined as the fixed stop symbol with a higher probability than other symbols.

  In the gaming machine according to the first and second aspects of the present invention, a combination of symbols in which the number of fluctuations, which is the total number of occurrences of the first fluctuation period and the second and subsequent fluctuation periods, is associated with a number having the predetermined relationship. The degree of expectation that a jackpot will occur can be set high. In these gaming machines, an unprecedented presentation effect can be realized in which the type of symbol with high expectation changes dynamically at each temporary stop until the combination of the confirmed stop symbols is confirmed. . Therefore, according to the gaming machines of the first and second inventions, unlike the gaming machines described in Patent Documents 1 and 2, the pattern type having a high expectation for jackpot can be changed into a single pattern. The possibility of falling can be suppressed and the interest of the game can be kept high.

  When the temporary stop occurs, the player of the gaming machine according to the first and second aspects of the invention becomes more interested in what number the next fluctuation period is. And, if a reach or the like by a symbol associated with a number having the predetermined relationship with respect to the number of occurrences of the variation period that has actually occurred after the symbol variation means starts displaying variation of a new symbol, The player's expectation for the jackpot can be explosively boosted at once. Thus, in the game of the gaming machine of the first and second inventions, since the place of power such as “Okay, here! Is possible. According to the gaming machine, it is possible to draw out the player's explosive expectation with respect to the jackpot, thereby enhancing the interest of the game. In this respect, it is greatly different from the gaming characteristics of the gaming machine described in Patent Document 3 or 4.

  As described above, the gaming machine according to the first and second aspects of the present invention is a gaming machine that variably displays a symbol and gives a privilege according to the symbol that is stopped and displayed, and enhances the effect of the display by the variation display of the symbol, It has excellent characteristics that it can maintain a high level of entertainment for a long time.

The gaming machines of the first and second inventions include various forms such as a pachinko machine using a pachinko ball (ball) as a game medium, a slot machine, and the like. Further, the slot machine may be a slot machine in a narrow sense using medals or the like as a game medium, or a parrot (R) or the like using a pachinko ball as a game medium.
In addition, the number of occurrences of the variation period in one symbol variation may be one. In this case, the temporary stop pattern in which the temporary stop symbol is stopped is not generated, and the pattern variation pattern in which the second and subsequent variation periods do not occur.

  Further, the predetermined relationship between the number of fluctuations and the number includes various relationships such as a match between the two, a relationship such that if one is an even number, the other is an even number, and a relationship in which the difference between the two is constant. There is a serious relationship. That is, the predetermined relationship means a relationship that can be analogized to some extent from one of the number of fluctuations and the number.

In the first and second aspects, when the symbol variation means restarts the symbol variation display after the temporary stop, the symbol having a predetermined relationship with the number of variations in the variation pattern determined by the variation pattern selection means is associated. Any one of the symbols that are different from the received symbol and different from the confirmed stop symbol determined by the stop symbol determining means is cumulatively excluded from the plurality of types of symbols that are variably displayed by the symbol varying means. Accordingly, it is preferable to gradually reduce the types of symbols to be displayed in a variable manner at each temporary stop (Claim 3).

  In this case, every time the variation display of the symbol is resumed in response to the temporary stop, the types of symbols that are variably displayed are reduced. Therefore, the player's sense of expectation for the jackpot can be gradually raised every time the temporary stop is made. Note that excluding one of the symbols from the plurality of types of symbols means not only deleting a certain type of symbol but also replacing a certain type of symbol with another symbol to increase the number of the other symbols. Including that.

In addition, when the symbol changing means restarts the symbol change display after the temporary stop, at least one of the temporary stop symbols stopped and displayed by the temporary stop is excluded from the plurality of types of symbols. (Claim 4).
In this case, since any one of the temporary stop symbols is excluded, the player can clearly recognize that the types of symbols that are variably displayed are reduced. Depending on the type of symbol that is excluded, the player can be relieved and the player's expectation for the jackpot can be enhanced or suppressed. Thus, in the above case, the effect of the design changing means can be further enhanced.

Further, it is preferable that one symbol is excluded from the plurality of types of symbols for each temporary stop when the symbol changing means restarts the symbol change after the temporary stop.
In this case, the expectation can be gradually raised while maintaining a high tension of the player by reducing the kinds of symbols that the symbol changing means displays one by one for each temporary stop. it can. After that, if a reach or the like is generated by a symbol associated with a number having a predetermined relationship with the number of occurrences of the fluctuation period actually generated in the symbol variation, the player's expectation will be raised at a stroke. Become.

The embodiment of the present invention will be specifically described with reference to the following examples.
(Example)
This example is an example of a pachinko gaming machine collectively called a so-called seven machine. The contents will be described with reference to FIGS.
The gaming machine 1 of this example includes a lottery means 31 that executes a lottery process in response to establishment of a predetermined start condition, and a plurality of symbol display areas 190 that variably display a plurality of types of symbols associated with different numbers. In addition, the symbol changing means 35 for notifying the lottery result by the lottery means 31 by a combination of the fixed stop symbols stopped and displayed in the plurality of symbol display areas 190, and if the lottery result is a win, While determining the fixed stop symbol that is scheduled to be stopped and displayed in each symbol display area 190 so that the combination is the same symbol combination, if the lottery result is a loss, the combination of the fixed stop symbol combination is the same type Stop symbol determining means 32 for determining a fixed stop symbol scheduled to be stopped and displayed in each symbol display area 190 so that the symbol display area 190 does not become, and the plurality of symbol display areas 1 When the combination of the fixed stop symbols that are stopped and displayed at 0 is a combination of symbols of the same type, the privilege granting means 34 for granting a privilege to the player side, and the symbol variation means 35 displays a variation display of a new symbol. It is a gaming machine provided with variation pattern selection means 33 for selecting any one of a plurality of variation patterns set in advance each time it is started.

The symbol changing means 35 provided in the gaming machine 1 performs symbol change display and stop display according to the change pattern selected by the change pattern selecting means 33. The symbol change means 35 starts a new symbol variation as a variation pattern of one symbol variation from when the symbol variation means 35 starts displaying the variation of a new symbol until it stops displaying the combination of the fixed stop symbols. Alternatively, the first variation period until the temporary stop symbol is stopped and displayed in each symbol display area 190, and after the temporary stop when the temporary stop symbol is stopped and displayed, the variable display of the symbol is restarted and then the fixed stop symbol or temporary stop symbol is displayed. A plurality of variation patterns having different number of variations, which is the total number of occurrences of the second and subsequent variation periods until the symbol display area 190 is stopped and displayed, are set.
Further, when the lottery result is a win, the variation pattern selection means 33 is in a predetermined relationship (in this example, a matching relationship) with the number associated with the confirmed stop symbol determined by the stop symbol determination means 32. A variation pattern to which the number of variations is assigned is selected with a higher probability than other variation patterns.
Hereinafter, this content will be described in detail.

  First, the external configuration of the gaming machine 1 of this example will be described with reference to FIG. The gaming machine 1 is disposed on the left and right sides of the game area 13, the open / close door 12 attached to the underframe, the substantially circular game area 13 formed on the game board disposed inside the open / close door 12. A pair of left and right speakers 14, a ball supply tray 111 provided on the lower side of the game area 13, and a launching handle 112 disposed on the lower right are provided.

  As shown in FIG. 2, the open / close door 12 is a door that is fixed to the frame so as to face the gaming machine 1 and be rotatable via a left hinge 122. The open / close door 12 includes a substantially circular transparent window 120 corresponding to the game area 13, and a decorative lamp 126 disposed on the transparent window 120. Further, the open / close door 12 has a plurality of through holes 124 corresponding to the positions where the speakers 14 are disposed.

  The launch handle 112 is an operation handle for adjusting the launch strength of the ball into the game area 13. The firing handle 112 is biased toward an initial position in the left rotation direction by a spring (not shown). The launch strength when the firing handle 112 is located at the initial position is zero, and no ball is fired in this state. In the gaming machine 1, a ball is fired toward the game area 13 when the firing handle 112 is operated in the right rotation direction. As the operation amount of the firing handle 112 increases, the ball launch strength increases. Furthermore, the firing handle 112 includes a firing stop button (not shown) for temporarily stopping the firing of the ball. If the firing stop button is operated, the ball firing can be temporarily stopped in a state where the firing handle 112 is operated in the clockwise direction.

  As shown in FIG. 2, the game area 13 is an area in which pachinko balls that are game media flow down. The game area 13 is centered on a display device 19 having a liquid crystal display device 191, and includes a passing gate 175, a start winning device 17, which is an electric tulip (hereinafter abbreviated as electric Chu), a grand winning device 16, and a general display. A part 181 and a general-purpose hold display part 182 are provided. Further, a ball discharge port 15 is opened at the bottom of the game area 13 for collecting all balls that have flowed down without winning any of the winning ports.

  As shown in FIG. 2, the display device 19 includes a liquid crystal display device 191 disposed substantially at the center and a special figure holding display portion 192 disposed in the lower frame portion. In addition to the function as a special symbol display unit (a part of the symbol variation means 35) for displaying the result of a special symbol lottery (hereinafter referred to as a special symbol lottery), the liquid crystal display device 191 produces a game in a big hit state. It has a function to display a jackpot display. In the following description, the liquid crystal display device 191 as a special figure display unit is appropriately referred to as a special figure display unit 191.

  The special symbol display unit 191 has three symbol display areas 190L, C, and R for variably displaying a plurality of types of symbols. The special figure display unit 191 displays a lottery result of a special figure lottery (hereinafter referred to as a special figure lottery result) by a combination of three fixed stop symbols that are stopped and displayed in each of the symbol display areas 190L, C, and R. In this example, as the symbols to be variably displayed in each symbol display area 190L, C, R, seven types of symbols in which 1 to 7 Arabic numerals are designed are adopted.

  When displaying the special drawing lottery results, the special symbol display unit 191 starts the symbol variation display in the symbol display regions 190L, C, and R all at once, and after the elapse of a predetermined special symbol variation time, each symbol display region 190L. , C, R to stop the fixed stop symbol. The period from the start of the variable display of symbols at the same time starting from the state in which the fixed stop symbol is stopped in each symbol display area 190L, C, R until the combination of the fixed stop symbol is stopped again is displayed once. It corresponds to the design fluctuation of. And this symbol fluctuation | variation is comprised by the fluctuation | variation period of 1 time or 2 times or more. This fluctuation period is the fixed stop symbol or temporary stop after the symbol variable display is started or restarted from the state where the fixed stop symbol or temporary stop symbol is stopped and displayed in each symbol display area 190L, C, R. This is the period until a symbol is stopped and displayed in each symbol display area 190L, C, R.

  When the special figure drawing unit 191 wins the special figure lottery, the special figure display unit 191 notifies the fact by a combination of the same symbols (so-called double eyes). In this example, the variation pattern selecting means 33 selects the variation pattern time spent for one variation of the symbol from the start of the variation display of the symbol until the fixed stop symbol is stopped and displayed. Every one is different.

  The special figure hold display unit 192 is a display unit that displays the number of hold of the special drawing lottery result. The special figure hold display unit 192 has a plurality of LEDs (Light Emitting Diodes) arranged at substantially equal intervals in the horizontal direction. The number of LEDs arranged is four, which is the same as the maximum number of reserved special drawing results. The special figure hold display unit 192 displays the number of special figure lottery hold based on the number of LEDs lit.

  As shown in FIG. 2, the passing gate 175 is a gate that triggers a lottery of normal symbols (hereinafter referred to as a regular drawing lottery). At the passing gate 175, only the ball is passed, and the payout of the winning ball is not set. In the gaming machine 1 of this example, a passing gate 175 is disposed on the left side of the display device 19 so as to face the gaming area 13.

  The start winning device 17 is a winning opening serving as a trigger for a special drawing lottery that is a big hit lottery, and is arranged below the display device 19. The start winning device 17 of this example is a so-called electric chew in which a pair of movable blades 171 are provided in the opening 170. The pair of movable blades 171 in a normal state are in a standing state so as to face each other with a gap enough to allow balls to pass. In this state, only the upper opening portion in the gap formed by the pair of movable blades 171 becomes the ball winning path. On the other hand, the pair of movable blades 171 (shown by broken lines in FIG. 2) rotated so as to be separated from each other act like a tray that guides the inflow of balls into the opening 170. Therefore, in this state, the winning probability to the start winning device 17 is remarkably increased. The start winning device 17 opens the movable blade 171 in accordance with the winning in the usual drawing lottery (in this example, a winning probability of 1/1 is set). The opening time of the movable blade 171 is 0.2 seconds during normal times and during big hits, and 1.5 seconds × 3 times during time reduction and during probability change.

  As shown in FIG. 2, the universal map display unit 181 is a display unit that displays the universal map lottery result. The general map display unit 181 of this example is configured by one LED. The common map display unit 181 displays a fluctuating operation by blinking. The common map display unit 181 turns on the LED when the lottery result is a win, and turns off the LED when the lottery is lost. As for the normal time fluctuation time, it is 30 seconds during normal times and during jackpots, and 1 second during short hours and during probability changes.

  The general map hold display unit 182 is a display unit that displays the number of hold of the general drawing lottery result. The general-purpose hold display unit 182 has four LEDs arranged vertically. The general map hold display unit 182 displays the hold number of the general drawing lottery result (maximum general map hold number 4) according to the number of LEDs that are lit. Note that in the gaming machine 1 of this example, the common figure display unit 181 and the common figure hold display unit 182 are arranged on the left edge portion facing the game area 13.

  As shown in FIG. 2, the big winning device 16 is a variable winning opening called an attacker that opens in accordance with the jackpot. The grand prize winning device 16 includes an opening 160 having a horizontally long and substantially rectangular shape, and a lid member 161 that rotates around the lower side of the opening 160. In the grand prize winning device 16, the opening 160 is closed when the lid member 161 is positioned so as to be substantially flush with the surface of the game board forming the game area 13, while the lid member 161 is turned to the player side. If it moves, the opening part 160 will be in an open state. Further, the lid member 161 rotated in this way serves as a tray for guiding the ball to the opening 160. The large winning device 16 is arranged below the start winning device 17.

  Next, the system configuration of the gaming machine 1 will be described with reference to FIGS. 1 and 2. The gaming machine 1 is configured around a main circuit 20. For the main circuit 20, a payout control circuit 41 for controlling the payout and driving of balls, a sub-control circuit 43 for controlling game effects, an LED 460 for displaying various game data, a winning ball or passing ball detector 51.

  As shown in FIGS. 1 and 2, the payout control circuit 41 is a circuit that controls the payout of balls according to winning and the driving of balls. The payout control circuit 41 is electrically connected to the payout device 410 and the launch control circuit 42. The payout device 410 is a device that pays out a predetermined number of balls instructed by the main circuit 20 in accordance with winning. The firing control circuit 42 is a circuit that controls the launch strength of the ball by the firing device 421 in accordance with the amount of operation of the firing handle 112 that constitutes the handle device 422.

  The sub control circuit 43 is a control circuit for various game effects as shown in FIGS. For the sub-control circuit 43, an amplifier / speaker 431 including the speaker 14, decorative lamps 432 such as a decorative lamp 126, and a display control circuit 44 for controlling the liquid crystal display device (special display unit) 191 are electrically connected. It is connected. The display control circuit 44 constitutes the symbol changing means 35 together with the special figure display unit 191. The display control circuit 44 starts symbol variation in response to a variation start instruction signal input from the main circuit 20 via the sub-control circuit 43, and definitely stops symbol variation in response to a similar variation stop instruction signal. . The symbol changing means 35 of this example performs a temporary stop that seems to stop all symbols during one symbol change after the symbol change display is started until the combination of the fixed stop symbols is displayed. Continuous production is possible. The symbol variation means 35 executes symbol variation display according to the variation pattern selected by the variation pattern selection means 33.

  The display control circuit 44 of the present example includes a temporary stop symbol determination means 441 that determines a temporary stop symbol that is a symbol to be temporarily stopped by a temporary stop, and a symbol sequence that is variably displayed upon restarting the variable display of the symbol after the temporary stop. And a symbol string changing means 442 for changing and setting the. The temporary stop symbol determination unit 441 determines a temporary stop symbol when the variation pattern selection unit 33 determines a variation pattern including a temporary stop (a variation pattern with two or more variations). The symbol sequence changing means 442 cumulatively deletes any one of the symbols excluding the following specific symbols every time it is temporarily stopped. As the specific symbol, a symbol associated with a fixed stop symbol determined by the stop symbol determining unit 32 and a number corresponding to the number of fluctuations in the variation pattern selected by the variation pattern selecting unit 33 is set.

  Further, the display control circuit 44 has a function of causing the liquid crystal display device 191 to display an effect screen for producing a big hit game in addition to the function as the symbol changing means 35. The display control circuit 44 executes a jackpot display process in accordance with a jackpot start instruction signal, a round start instruction signal, and a jackpot end instruction signal, which will be described later, input from the main circuit 20. The jackpot state effect screen displayed on the liquid crystal display device 191 by the display control circuit 44 is a jackpot start display indicating the start of the jackpot state, a jackpot display during the continuation of the jackpot state, and an end of the jackpot state. There is a jackpot end display. In the description of this example, illustration of each effect screen is omitted.

As the detector, a gate passage detector 51 that detects a passing ball of the passing gate 175, a start winning detector 52 that detects a winning ball to the starting winning device 17, and a winning ball to the big winning device 16 are detected. And a big prize detector 53.
The electric Chu solenoid 54 is a solenoid for opening and closing the movable blade 171 of the start winning device 17.
The big winning solenoid 55 is a solenoid that rotates the lid member 161 of the big winning device 16 so that the big winning device 16 can be awarded.

  As shown in FIG. 1, the main circuit 20 has a CPU (Central Processing Unit) 21, ROM (Read Only Memory) 22 and RAM (Random Access Memory) 23 as storage means, and a random number for special drawing lottery or general drawing lottery. A random number extraction unit 25 for extraction, an input / output (I / O) 24 serving as an input / output interface, and the like are provided. The main circuit 20 of this example causes the CPU 21 to execute a program read from the ROM 22, thereby functioning as the lottery means 31, the stop symbol determining means 32, the privilege giving means 34, and the variation pattern selecting means 33. Realize.

  As shown in FIGS. 1 and 3, the ROM 22 stores various processing programs to be executed by the CPU 21, and stores several types of determination tables used for special drawing lottery or ordinary drawing lottery. The special figure determination table for special figure lottery is a data table in which a random number range corresponding to a loss, a random number range corresponding to a probable variation jackpot, and a random number range corresponding to a non-probable variation jackpot are defined. The general drawing determination table for the general drawing lottery is a data table in which a random number range corresponding to the loss and a random number range corresponding to the general drawing winning are defined.

  As the special figure determination table, there are a normal special figure determination table for the normal state or the short time state, and a probability changing special figure determination table for the probability variation state. As the common figure determination table, there are a normal common figure determination table in a normal state and a normal change determination normal figure determination table for a probability variation state or a short time state. Note that the random number range corresponding to the loss is not set in the common figure determination table of this example. Therefore, in the ordinary drawing lottery of this example, the winning of the ordinary drawing can occur with a probability of 100%.

  As shown in FIG. 3, the RAM 23 is a readable / writable storage means used for the work area of the CPU 21 and temporary writing. In the storage area of the RAM 23, a special figure reservation storage area and a general figure reservation storage area are allocated for each four data, and a stop symbol storage area and a variation pattern storage area are allocated. The special figure holding area is a storage area for storing (holding) a special figure lottery result, that is, a random number extracted according to the special figure lottery. The general map holding area is a storage area for storing (holding) random numbers extracted according to the general drawing lottery result, that is, the general drawing lottery. The stop symbol storage area is an area for storing the stop symbol determined by the stop symbol determination means 32. The fluctuation pattern storage area is an area for storing the fluctuation pattern selected by the fluctuation pattern selection means 33.

  As shown in FIG. 1, the random number extraction unit 25 is a means for extracting random numbers for special drawing lottery and ordinary drawing lottery. The random number extraction unit 25 extracts a random number from the integers generated by the random number counter 250. The random number extraction unit 25 extracts random numbers for the normal drawing according to the detection of the passing ball by the gate passage detector 51, while the random number extraction unit 25 for the special drawing lottery according to the detection of the winning ball by the start winning detector 52. Extract random numbers. The random number counter 250 generates an integer in the range of 1-60000 for special drawing lottery.

  As shown in FIGS. 1 and 3, the lottery means 31 is a means for executing a special drawing lottery or a general drawing lottery. The lottery means 31 takes in the random numbers extracted by the random number extraction unit 25 in the special drawing lottery or the general drawing lottery. The lottery means 31 is used for special drawing lottery via the random number extraction unit 25 when the number of holdings of the special drawing lottery result (general drawing lottery result) in the special figure holding area (general drawing holding area) is 3 or less. The random number for the lottery is extracted, and when the number is 4, the extraction of the random number for the special drawing lottery (for the regular drawing lottery) is canceled. The lottery means 31 uses the random number for the special drawing lottery (for the special drawing lottery) extracted by the random number extraction unit as a special drawing lottery result (the general drawing lottery result) in the empty area of the special drawing holding area (the general drawing holding area). Store sequentially.

  The lottery means 31 is able to start displaying the fluctuation of the special figure (ordinary figure), that is, when the special figure (general figure) is not fluctuating and is not during the big hit (during the operation of the electric figure), The presence or absence of a special drawing lottery result (general drawing lottery result) stored in the holding area (ordinary drawing lottery area), that is, held is confirmed. The lottery means 31 reads out the oldest of the special drawing lottery results (ordinary drawing lottery results) stored in the special figure holding area (normal drawing holding area) and collates it with the special drawing determination table (common drawing determination table). . The lottery means 31 selects and uses a type of determination table corresponding to the gaming state as described above. As a lottery result of the special drawing lottery, there are a probability variation jackpot, a non-probability variation jackpot and a loss. The lottery result of the regular drawing lottery is only winning in this example. In this example, the probabilities of the loss, the probability variation jackpot, and the non-probability variation jackpot in the special drawing lottery are 59800 / 60,000, 100, and 100, respectively.

  The stop symbol determining means 32 is a means for determining a stop symbol to be stopped and displayed in each symbol display area 190L, C, R of the special symbol display unit 191 as shown in FIGS. The stop symbol determination means 32 determines a stop symbol according to the special symbol lottery result. When the special symbol lottery is won, the stop symbol determination means 32 determines the same type of symbols as the stop symbols to be stopped in each symbol display area 190L, C, R. In the case of a probable big hit, a symbol associated with an odd number among 1 to 7 is determined as a stop symbol. In the case of a non-probable big hit, a symbol associated with an even number among 1 to 7 is determined as a stop symbol.

  As shown in FIGS. 1 and 4, the variation pattern selection means 33 has a plurality of variations in which the number of variations, which is the total number of occurrences of the first variation period and the second and subsequent variation periods, is different. A means for selecting one of the patterns. The fluctuation pattern selection means 33 selects a fluctuation pattern based on a random number for special drawing lottery. In this example, a variation pattern in which reach occurs and a variation pattern in which reach does not occur are set as the variation pattern. Furthermore, as the variation patterns in which reach occurs, seven types of variation patterns of effects B to H, which are different in the number of variations, which is the number of occurrences of the variation period in one symbol variation, are set. Production A is set as a variation pattern in which reach does not occur. The contents of each variation pattern are as follows. The special symbol variation time is the time spent from the start of the symbol variation display to the time when the combination of the fixed stop symbol is stopped and displayed. In addition, the following special figure fluctuation time is a time when there is no special figure hold in a normal state. When there is a special figure hold, and when it is in a short time state or a certain change state, the special figure fluctuation time is shortened.

<Note>
Production A: Fluctuation pattern where no reach occurs. Special figure change time 10 seconds.
Production B: Number of fluctuations once (temporary stop 0 times). Special figure change time 20 seconds.
Production C: Number of fluctuations twice (temporary stop once). Special figure change time 25 seconds.
Production D: Number of fluctuations 3 times (2 temporary stops). Special figure change time 30 seconds.
Production E: Number of fluctuations 4 times (3 temporary stops). Special figure change time 35 seconds.
Production F: Number of fluctuations 5 times (4 temporary stops). Special figure change time 40 seconds.
Production G: 6 fluctuations (5 temporary stops). Special figure change time 45 seconds.
Production H: Number of fluctuations 7 times (6 temporary stops). Special figure change time 50 seconds.

  The selection probability of each variation pattern by the variation pattern selection means 33 of this example will be described with reference to FIG. Each figure in FIG. 4 shows, in order from the left, the selection probability in the case of a loss, the selection probability in the case of a probable variation jackpot, and the selection probability in the case of a non-probable variation jackpot. In the figure, each column in the vertical direction corresponds to effects A to H. Also, the “number of selections” column arranged in the horizontal direction indicates the number of random numbers assigned to each variation pattern among 60000 which is the number of random numbers for special drawing. In the figure, reach A represents reach by a symbol associated with a number corresponding to the number of changes in each change pattern. Reach B represents the reach by symbol associated with a number other than the number of changes in each change pattern. The columns of “reach A” and “reach B” show a breakdown of the number of random numbers displayed in the selection number. In the effects B to H including the temporary stop, a temporary stop time from the start of the symbol variation display (including the restart after the temporary stop) to the temporary stop is separately defined.

  As can be seen from FIG. 4, the number of random numbers assigned to reach A and the random number assigned to reach B in the case of jackpot regardless of whether it is probabilistic or non-probable and in the case of loss. The ratio with the number of is reversed. That is, in the case of a loss, the number of assigned random numbers is about 10 times that of reach A in reach B, whereas in the case of a big hit, reach A is about 4 times that in reach B. Therefore, in the gaming machine 1 of this example, if a reach is generated by a symbol associated with a number corresponding to the number of fluctuations, which is the number of occurrences of a fluctuation period caused by one symbol fluctuation, there is a high possibility that it is a big hit. become. Further, in the case of a probable big hit, nearly 100% of the winning random numbers are assigned to the effects B, D, F, and H whose number of fluctuations is odd. On the other hand, in the case of a non-probable big hit, nearly 100% of the winning random numbers are assigned to the effects C, E, and G whose number of changes is an even number.

  The privilege granting means 34 is a means for generating a jackpot (privilege) according to the combination of the confirmed stop symbols that are definitely stopped and displayed on the special figure display unit 191. In the privilege grant means 34, a jackpot flag corresponding to the jackpot state is set. When the combination of the fixed stop symbols is the same symbol combination (so-called double eyes), the privilege granting unit 34 sets the jackpot flag to the on state and generates a jackpot state. The big hit state is a gaming state advantageous to the player side in which a round in which the big winning device (attacker) 16 is opened is repeated with 10 winning balls or an opening time of 25 seconds as an end condition.

  The privilege granting unit 34 repeatedly executes the round 15 times, resets the jackpot flag to the off state, and ends the jackpot state. The privilege granting unit 34 transmits a big hit start instruction signal, a round start instruction signal, and a big hit end instruction signal corresponding to the big hit state to the display control circuit 44. The big hit start instruction signal is a signal instructing the start of the big hit state. The round start instruction signal is a signal instructing the start of each round. The big hit end instruction signal is a signal instructing the end of the big hit state. In addition, the privilege provision means 34 is provided with the round counter (not shown) which is a counter for counting the frequency | count of execution of a round. The privilege grant means 34 controls the occurrence period of the jackpot state by the number of rounds which is the counter value of the round counter.

  The privilege granting unit 34 generates a probability variation jackpot when the combination of the fixed stop symbol is an odd-numbered symbol, and after the probability variation jackpot ends, generates a probability variation state that continues until a new jackpot occurs. . In the probability variation state, the special map lottery is performed by the probability variation special map determination table. On the other hand, when the combination of the fixed stop symbols is an even-numbered symbol, the non-probable variation jackpot is generated, and the time-short state is generated after the non-probable variation jackpot ends. The short-time state is a state in which a special drawing lottery is carried out using the normal special drawing determination table, and ends according to the establishment of any one of 100 symbol variations and the occurrence of a new jackpot. Note that, in the probability variation state and the short time state of the present example, the opening time of the start winning device (electric chew) 17 at the time of the normal winning is prolonged, so the degree of decrease of the player's holding ball is suppressed. Note that when the time reduction state ends, the normal state is restored.

  Next, the operation of the gaming machine 1 of the present example configured as described above will be described along the flowcharts of FIGS. FIG. 5 shows the flow of the start winning process according to the winning to the start winning device (electrical chew) 17. FIG. 6 shows the flow of the display start process for starting the symbol variation of the special figure display unit 191. FIG. 7 shows a flow of special figure reading processing for reading a special figure lottery result stored (held) in the special figure reservation area. FIG. 8 shows the flow of special figure fluctuation processing by the main circuit 20 for causing the special figure display unit 191 to execute symbol fluctuation. FIG. 9 shows the flow of the special figure changing process by the display control circuit 44 for causing the special figure display unit to execute the symbol fluctuation. FIG. 10 shows the flow of a jackpot process for generating a jackpot state. FIG. 11 shows the flow of a jackpot display process by the display control circuit 44 for causing the liquid crystal display device 191 to execute a game effect while the jackpot state is occurring.

  In the start winning process shown in FIG. 5, the main circuit 20 first determines whether or not a winning ball of the start winning device 17 is detected (S101). When a winning ball is detected (S101: YES), the number of reserved special drawing lottery results in the special figure holding area is determined (S102). If the hold number is 3 or less (S102: YES), one of the random numbers generated by the random number counter 250 (random value at that timing) is extracted (S103), and the special figure hold area is entered. Hold (store) the latest special drawing lottery result (S104). On the other hand, when the winning ball of the start winning device 17 is not detected (S101: NO), or when the number of holdings of the special drawing lottery result in the special drawing holding area is four (S102: NO), the random number extraction unit 25 The start winning process is terminated without executing random number extraction by.

  In the display start process shown in FIG. 6, the main circuit 20 first determines whether or not a big hit state is occurring (S201). When the big hit state is not occurring (S201: NO), it is determined whether the special symbol display unit 191 is displaying the symbol variation (S202). If the symbol variation is not performed (S202: NO), it is determined whether or not there is a special drawing lottery result stored (held) in the special drawing holding area (S203). If the special figure lottery result is stored (S203: YES), a special figure reading process P1 for reading from the oldest one is performed.

  In the special figure reading process P1, as shown in FIG. 7, the main circuit 20 reads out the special figure lottery result held in the special figure holding area with the oldest extraction time (S301), and the game at that time The winning / failing determination is executed by collating with a special figure determination table corresponding to the state (normal state, probability variation state, time reduction state) (S302). As described above, the variation pattern selection means 33 determines the variation pattern according to the determination result, that is, the special figure lottery result (S303), and the stop symbol determination means 32 determines the stop symbol (S304). Thereafter, a special figure changing process P2 for changing the symbol is performed in the special figure display unit 191. As the special figure fluctuation process P2, there are a special figure fluctuation process P21 by the main circuit 20 as shown in FIG. 8, and a special figure fluctuation process P22 by the display control circuit 44 as shown in FIG.

  As shown in FIG. 8, in the special figure fluctuation process P21 by the main circuit 20, the main circuit 20 firstly changes the fluctuation pattern selected by the fluctuation pattern selection means 33 and the change indicating the fixed stop symbol determined by the stop symbol determination means 32. A start instruction signal is transmitted to the display control circuit 44 (S401). Thereafter, after the elapse of the special figure fluctuation time corresponding to the selectively determined fluctuation pattern (see S303 in FIG. 7) (S402: YES), a fluctuation stop instruction signal is transmitted to the display control circuit 44 ( S403). After the symbol change display is definitively stopped, it is determined whether or not the combination of definite stop symbols is a jackpot symbol (S404). If it is a big hit symbol (S404: YES), the big hit flag is set to the on state (S405), and a big hit start instruction signal is transmitted to the display control circuit 44 (S406).

  As shown in FIG. 9, in the special map variation process P22 by the display control circuit 44, the display control circuit 44 first determines whether or not a variation start instruction signal has been received from the main circuit 20 (S501). When the variation start instruction signal is received (S501: YES), it is determined whether or not the variation pattern instructed by the variation start signal is the effect A (S502). When it is any of the effects B to H including temporary stop (S502: NO), the temporary stop symbol determining means 441 determines the temporary stop symbol (S503).

  Thereafter, the display control circuit 44 starts the variable display of symbols in the symbol display areas 190L, C, and R of the special symbol display unit 191 all at once (S504). When any of the effects B to H is selected by the variation pattern determination unit 33 (S505: NO), the processing after S506 described below is executed. On the other hand, when the production A is selected (S505: YES), the processing of S506 to S510 is bypassed.

  When any one of the effects B to H is selected (S505: NO), the display control circuit 44 determines the lapse of the temporary stop time, which is the symbol variation time until the temporary stop is performed ( S506). When the temporary stop time has elapsed (S506: YES), the symbol variation display on the special symbol display unit 191 is temporarily stopped and the temporary stop symbol is stopped and displayed (S507). Thereafter, when the symbol variation display is resumed, the symbol sequence changing means 442 changes the symbol sequence (deletes the predetermined symbol) (S508), and then resumes the symbol variation display on the special symbol display unit 191 (S509). If it is the last fluctuation period at the time when all the fluctuation numbers in the fluctuation pattern are consumed (S510: YES), the main circuit 20 waits for reception of a fluctuation stop instruction signal (S511). When the change stop instruction signal is received (S511: YES), the change display of symbols on the special symbol display unit 191 is definitely stopped, and the combination of fixed stop symbols is stopped and displayed (S512).

  In the jackpot process as shown in FIG. 10, the main circuit 20 first determines the flag state of the jackpot flag (S601). If the jackpot flag is on (S601: YES), the counter value of the round counter indicating the number of rounds is incremented by 1 (S602), and a round start instruction signal is transmitted to the display control circuit 44 (S603). ). Thereafter, until the number of winning balls reaches 10 (S605) or until the opening time reaches 25 seconds (S606), the large winning device (attacker) 16 is opened (S604) and then closed (S607). .

  The main circuit 20 repeatedly executes the process of releasing the special winning device 16 as described above until the number of rounds reaches 15 (S608). When the number of rounds reaches 15 (S608: YES), the big hit flag is reset to an off state (S609), and a big hit end instruction signal is transmitted to the display control circuit 44 (S610).

  Next, in the jackpot display processing by the display control circuit 44 as shown in FIG. 11, the display control circuit 44 first determines whether or not to receive a big start instruction signal (S701). When the big hit start instruction signal is received (S701: YES), a big hit start display (not shown) indicating the start of the big hit state is displayed on the liquid crystal display device 191 (S702). When the round start instruction signal of the main circuit 20 is received (S703: YES), a jackpot display (not shown) including a round number display is displayed on the liquid crystal display device 191. The display control circuit 44 adds the number of rounds to be displayed in the round number display, one round at a time each time a round start instruction signal is received (S704).

  If the number of digestion rounds has reached 15 (S705: YES), the display control circuit 44 waits for the main circuit 20 to receive the big end instruction signal (S706). When the big hit end instruction signal is received (S706: YES), a big hit end display (not shown) indicating that the big hit has ended is displayed on the liquid crystal display device 191 (S707).

  A variation pattern of symbol variation in the special symbol display unit 191 of the gaming machine 1 configured as described above will be described with reference to FIG. In the figure, as the variation pattern, an effect D having a variation count of 3 (a variation period occurrence count of 3) is determined. The circled numbers 14 to 20 and the circled numbers 14 ′ to 20 ′ are finally displayed when a big hit occurs (when “333 (3 reach)” is determined as a definitive stop symbol) The case (when “232 (2 reach)” is determined as the fixed stop symbol) is selectively displayed.

  In the figure, the circled number 2 corresponds to the start of the first variable period, and the circled numbers 8, 14 (14 ') correspond to the restart of the second and subsequent variable periods due to the fluctuation start after the temporary stop. doing. The circled numbers 5 and 11 correspond to a temporary stop, and the circled number 17 (17 ') corresponds to a state in which a reach has occurred with the symbol display area 190C remaining. A circled numeral 18 (18 ′) indicates a state in which the symbol is stopped and displayed in the symbol display area 190C, and a circled numeral 19 (19 ′) indicates a state in which the combination of the fixed stop symbol is stopped and displayed. . That is, in the figure, circled numbers 2 to 19 (19 ′) correspond to one symbol variation, while circled numbers 2 to 5 correspond to the first variation period, and circled numbers 8 to 11 represent Corresponding to the second variation period, circled numbers 14 (14 ′) to 19 (19 ′) correspond to the third variation period.

  The circled numbers 6 to 7 and the circled numbers 12 to 13 are effects when deleting “4” or “6” which is one of the symbols displayed by the temporary stop (the symbol row changing means 442). Is shown. Then, in the second variable period restarted at the circled numeral 8, the variable display of the symbol sequence consisting of “1” to “3” and “5” to “7” is executed, and the circled numeral 14 (14 ′ In the third variation period restarted at (), the variation display of the symbol sequence consisting of “1” to “3”, “5” and “7” is executed. Here, in the case of FIG. 12, the symbol “3” corresponding to the number of fluctuations is the specific symbol that is not a deletion candidate. Furthermore, “3” (“2” in the case of a loss) determined as the fixed stop symbol of the left and right symbol display areas 190L and R is also set as a specific symbol that is not a deletion candidate. In the case of a jackpot, the probability that the symbol corresponding to the number of changes matches the symbol determined as the fixed stop symbol is high.

  As described above, the gaming machine 1 according to the present example is a gaming machine that displays a symbol in a variable manner and gives a privilege according to the symbol that is stopped and displayed. It is a gaming machine with excellent characteristics that can keep the interest of the game high.

  In this example, the reach is not generated at the time of temporary stop, but instead, the lost eye after the reach has occurred can be temporarily stopped. However, when a temporary stop is caused by a loss after a reach has occurred, it is preferable that the symbol associated with a number other than the number of occurrences of the fluctuation period that actually occurred before the temporary stop in the symbol change is the reach symbol. . For example, when the variation pattern of the effect D with the number of variations of 3 is selected, if a reach with the symbol “2” occurs in the second variation period, the player may be hit ... Will be watched over the display of the variation of the symbol, and the player's attention may be dispersed. Therefore, in symbol variation, the probability of losing reach due to symbols corresponding to the number of occurrences of the fluctuation period that has actually occurred up to that point can be kept lower than the probability of losing reach due to symbols other than the symbol concerned. preferable. More preferably, in the symbol variation, it is preferable to set the occurrence probability of the losing reach due to the symbol corresponding to the number of occurrences of the variation period actually generated up to that point to 0%.

  Furthermore, in this example, the special symbol display unit 191 sets seven types of symbols “1” to “7” to be variably displayed, and sets the upper limit of the number of executions to start symbol variation to seven times. . The number of types of symbols may be set to 7 or more, the number of occurrences of the variation period may be set to 7 or more, the number of types of symbols is set to 7 or more, and the number of occurrences of the variation period is set to 7 You may set more than once. Furthermore, the number of variations, which is the number of occurrences of the variation period in symbol variation, may be made different from the number of symbol types. For example, even if there are twelve kinds of symbols “1” to “12” and the upper limit of the number of fluctuations is set to eight, the same effect as this example can be realized.

  Further, in this example, when the variable display of symbols is resumed after a temporary stop, the types of symbols are cumulatively reduced one by one. Alternatively, two or more kinds of symbols can be reduced at a time when the variable display of symbols is resumed after a temporary stop. For example, when the production H with the number of fluctuations of 7 is selected, only 7 types can be reduced because there are only 7 types of symbols, but the production B or the production C with a small number of fluctuations is selected. It is also possible to reduce two or more types at a time. From the point of view of the player, when the variation display of a symbol is resumed after a temporary stop, if only one type of symbol is reduced, a variation pattern with a large number of variations is selected, and the expectation of being a big hit is high. Judgment is possible.

  Further, in this example, in order to avoid complication of the explanation, there is no mention of a fluctuation pattern such as re-fluctuating a temporarily stopped non-probable variation jackpot symbol and promoting it to a probable variation symbol. Of course, such a variation pattern can be combined with the configuration of this example. Further, it is possible to generate a jackpot with a non-probability variable symbol in the case of a probable change jackpot, and to notify that the jackpot game is actually probable during the jackpot game or after the jackpot is over. This example embodies an invention for the purpose of generating moments during which the expectation for jackpots increases at a stretch during continuous production. As long as this object is satisfied, various other configurations can be combined with this example.

  In this example, after a variation pattern is selected according to the special drawing lottery result, a fixed stop symbol is determined according to the selected variation pattern. Instead of this, it is also possible to first determine the fixed stop symbol in accordance with the special drawing lottery result, and then select the variation pattern in accordance with the determined fixed stop symbol. In this case, it is preferable to select a fluctuation pattern to which the same number of fluctuations as the number associated with the fixed stop symbol are assigned with higher probability than a fluctuation pattern to which other fluctuations are assigned.

  In this example, it is configured such that, when reaching a symbol associated with a number corresponding to the number of variations in the number of symbol variations (the number of occurrences of the variation period), the expectation level for jackpot increases. Instead, reach with a symbol associated with an even number when the number of variations is even, a symbol associated with an odd number when the number of variations is odd, or a symbol associated with a number corresponding to the number of variations + α. Then, it may be configured so that the degree of expectation that becomes a big hit becomes high. In either case, the expectation of jackpot when the relationship between the number associated with the symbol that will be reached and the number of fluctuations is in a predetermined relationship will be significantly higher than in the case where there is no predetermined relationship. It only has to be set. If it is set in this way, the player will be able to clearly recognize the place where the power is “Okay, here!”, And the fun of the game can be sufficiently enhanced.

  Furthermore, this example is an example relating to a pachinko gaming machine. The gaming machine 1 of this example can be replaced with a slot machine. In the case of a slot machine, in addition to a main drum (main reel) for displaying a lottery result, it is preferable to provide an effect liquid crystal display device for informing the lottery result. According to the production liquid crystal display device or the like, it is possible to implement the same variation pattern as in this example, and it is possible to achieve the effect of raising the player's expectation for a bonus prize at once.

It should be noted that the numerical values and the like shown in this example, such as the selection probability of each variation pattern and the probability of reach occurring in a symbol associated with the number corresponding to the number of variations, are all examples and can be changed as appropriate.
As mentioned above, although the specific example of this invention was demonstrated in detail, this specific example only discloses an example of the technique included by a claim. Needless to say, the scope of the claims should not be construed as limited by the configuration, numerical values, or the like of the specific examples.
