Description

  The present invention relates to a slot machine using game balls as game media.

  Conventionally, for example, a slot machine using a game ball (pachinko ball) as a game medium, a so-called parrot (R) has been proposed (see Patent Document 1). As such a parrot (R), for example, there is one that requires five pachinko balls with a unit price of 4 yen per bet. In such a parrot (R), five pachinko balls are associated with one bet, thereby realizing the same gambling as a slot machine using a medal with a unit price of 20 yen as a game medium. According to such a parrot (R), it is possible to install on a pachinko island where pachinko machines are lined up in a game store, and the degree of freedom of installing a slot machine can be greatly improved.

  However, the conventional slot machine using the game balls as the game medium has the following problems. That is, since the number of game media required for one game increases, the time required to insert the game media tends to increase. Therefore, there is a problem that speedy game progress is hindered and there is a possibility that sufficient interest of the game cannot be secured.

JP 2002-346041 A

  The present invention has been made in view of the above-described conventional problems, and in a slot machine that uses game balls, suppresses the possibility of speedy game progression being hindered due to game ball take-in operations, It is intended to provide a slot machine that enhances the fun of.

The present invention includes an internal lottery means for drawing an internal winning combination and setting the selected internal winning combination as a winning winning combination in a state where a winning can be achieved, and a game ball storage unit for storing game balls used for games as game media In the slot machine provided with a game ball taking-in means for taking in the game balls stored in the game ball storage unit,
An intake control means for controlling the operation of taking in the game balls by the game ball taking-in means;
A pre-acquisition ball number determining means for determining a pre-acquisition ball number that is the number of captured ball of the game ball to be applied to a later game among time-continuous games, according to the winning combination ,
A bet button operated by a player to apply the game ball to the game ,
In response to the operation of the bet button, the number of game balls applied to the game is subtracted from the number of game balls taken in by the game ball taking-in means,
The capture control means captures the game balls having the number of pre-acquisition balls determined by the pre-acquisition ball number determining means during the execution period of the previous game among the time-continuous games. The slot machine is configured to control the game ball take-in means (claim 1).

  The slot machine according to the present invention includes the take-in control means for controlling the take-in operation of the game balls by the game ball take-in means, and the pre-take-in that determines the number of pre-take-in balls according to the winning combination. And a ball number determining means. The take-in control means is configured to take the game balls of the pre-take-in number of balls to be used for the subsequent game during the execution period of the previous game among the temporally continuous games. Control the capture means.

  According to the slot machine, the game balls corresponding to the number of pre-taken balls can be taken in during the execution of the previous game. Therefore, after starting the previous game, when starting the subsequent game, it is possible to suppress the number of game balls to be newly captured for the subsequent game, and to shorten the time required for the capture. Further, in the slot machine, there is a correlation between the number of pre-taken balls to be taken in advance and the winning combination that is established in the previous game. Therefore, the player can enjoy the possibility of predicting the winning combination based on the number of the pre-taken balls, which is the number of game balls taken in the previous game.

  As described above, the slot machine using the game balls of the present invention enables the advancement of the game by speedily progressing the game by taking in the game balls in advance, and the prediction of the winning winning combination. It is a thing.

In the present invention, it is preferable to set the number of game balls necessary for the game in accordance with the ratio between the medal lending unit price and the gaming ball lending unit price. For example, if the lending unit price of game balls is 4 yen per piece for a medal with a lending unit price of 20 yen, it is preferable to set the number of game balls required for one bet to five. In this case, the monetary burden required for one bet can be matched between the slot machine using medals as game media and the slot machine using game balls as game media.
For the internal winning combination, for example, an internal winning flag or the like may be set. In this case, the winning combination combination can be managed with high certainty using the internal winning flag.

  The slot machine may be one that can use medals in addition to game balls. For example, it may be a slot machine capable of playing by combining game balls and medals, such as 3 bets with 5 game balls and 2 medals. Alternatively, when starting a game, a slot machine in which a player can selectively set whether to play with a game ball or to play with a medal may be used.

Further, it is preferable that the pre-acquisition ball number determining means is configured to determine zero as the pre-acquisition ball number when the winning combination is a replay combination (claim 2). .
In this case, it is possible to prevent a situation in which the game ball is taken in advance even though the replay combination has won. Therefore, if the number of pre-taken balls when the replay role is the winning combination is zero, it is possible to avoid the need to return the game balls pre-taken according to the winning of the replay role.

The pre-acquisition ball number determining means is configured to be able to determine the number of balls corresponding to the minimum bet ball number by lottery as the pre-acquisition ball number when the winning combination is a bonus combination. (Claim 3).
Here, the minimum bet number means the number of game balls required for the minimum bet unit in the slot machine game. In the above case, when the minimum bet ball number is pre-taken as the pre-taken ball number, the player can expect the internal winning of the bonus combination. Furthermore, if the minimum bet ball number is set as the pre-acquisition ball number, it is possible to aim to avoid wasting the game ball in an attempt to win a bonus combination in the subsequent game. In the above game where the bonus combination is won, if the bonus combination suddenly wins, it is preferable to additionally take in the game balls until the number of balls corresponding to the maximum bet is reached.

In addition, it includes a take-in timing determining means for determining a pre-take-in timing that is a timing for taking in the game ball according to the winning combination,
The take-in control means is configured to take in the game ball take-in means so as to take in the pre-take-in ball number determined by the pre-take-in ball number determination means at the pre-take-in timing determined by the take-in timing determination means. It is preferable to be configured to control (Claim 4).

  In this case, the advance acquisition timing, which is the timing at which the game balls are acquired in advance, changes according to the winning combination. Since the player can estimate the winning combination according to the pre-take-in timing, the interest of the game is further enhanced. The pre-fetching timing may be a single timing or a plurality of timings. When a plurality of timings are set as the pre-acquisition timing, the game balls corresponding to the number of pre-acquisition balls are divided and captured at a plurality of timings.

  The betting ball number display unit 114 displays the betting ball number according to the operation of the betting button 64. The number of bet balls is based on the balls taken in by the ball take-in unit 56. For this reason, the bet button 64 is set to be operable only when the number of balls displayed on the captured ball number display unit 115 is sufficient. When the bet button 64 is operated, the number of balls displayed on the bet ball number display unit 114 is incremented by one as the number of balls displayed on the captured ball number display unit 115 is decremented by one.

  As shown in FIGS. 1, 2, and 4, the reel 2 includes a left reel 2L, a middle reel 2C, and a right reel 2R. Each of the reels 2L, 2C, and 2R is a rotary reel that has a substantially cylindrical shape and has seven types and 21 symbols 20 arranged at a substantially constant interval on the outer peripheral surface thereof. Each reel 2L, 2C, 2R has a reference position piece (not shown) at one reference position in the rotation direction. The reference position piece is a member as a detected piece detected by a reference position detection unit 66 described later. In addition, as the reel 2, an image-type reel that variably displays symbols on the liquid crystal display can be employed instead of the rotary reel of this example.

As shown in FIGS. 1 and 2, the left reel 2 </ b> L forms one column at the left end in a three-row × three-column two-dimensional matrix displayed in the symbol display window 11. The right reel 2R forms one row at the right end in the two-dimensional matrix. The middle reel 2C forms a central row in the two-dimensional matrix. In this example, the arrangement order of the seven types of symbols 20 is changed for each reel 2L, 2C, 2R.
As shown in FIGS. 1 and 2, the liquid crystal display unit 530 has a function of notifying the player of the internal winning flag. In addition to the flag notification screen, the liquid crystal display unit 530 of this example displays various effect screens for directing games.

Next, the slot machine 1 of this example has a mechanical configuration as shown in FIG.
A control board 3 for controlling the overall operation of the slot machine 1 and each part electrically connected to the control board 3 will be described with reference to FIGS. In addition to the above-described configuration, the control board 3 includes a ball take-in unit 56 that takes in game balls used in the game, a throw-in ball detection unit 63 that detects game balls taken into the ball take-in unit 56, and the reel 2. A reel driving unit 51 for rotating the reel, a reference position detecting unit 66 for detecting the rotational position of the reel 2, a ball paying unit 54 for paying out game balls, various display units 55 for producing a game, and a player A set value operation unit 68 for setting a set value representing the degree of advantage of the game, an audio output unit 52 for controlling the speaker 520, and a decorative lamp unit 53 for visually producing a game are electrically connected.

As shown in FIGS. 1 and 2, the ball take-in portion 56 is configured to take one game ball supplied from the guide passage 141 of the supply tray 14 one by one. The ball take-in portion 56 includes a sprocket (not shown) corresponding to the guide passage 141 and provided with three recesses on the outer periphery. The ball take-in part 56 takes in game balls stored in the recess one by one in accordance with the rotation of a sprocket that is rotationally driven by a motor (not shown).
As shown in FIGS. 1 and 2, the inserted ball detection unit 63 is configured to detect a game ball taken in by the ball take-in unit 56 according to the rotation of the sprocket. The inserted ball detection unit 63 outputs a take-in signal every time a game ball is taken in.

  As shown in FIG. 1, the reel drive unit 51 includes a stepping motor (not shown) that can be controlled in units of steps, and is configured to rotationally drive the reel 2 by the rotational driving force of the stepping motor. This stepping motor is configured to rotate step by step for each control pulse fetched from the control board 3. The reel driving unit 51 is configured to take in the fluctuation start signal and start the rotation of the reel 2, and to take in the fluctuation stop signal and stop the reel 2.

  As shown in FIG. 1, the reference position detection unit 66 has a sensor that detects the passage of the reference position piece of each reel 2L, 2C, 2R and outputs a detection signal. As will be described in detail later, in this example, each reel 2L is based on the number of control pulses generated by the control board 3 after the generation of this detection signal, that is, the number of steps the stepping motor has rotated after passing the reference position piece. 2C and 2R calculate the symbol currently displayed (the symbol located on the winning line).

As shown in FIGS. 1 and 2, the ball dispensing unit 54 is configured to dispense a predetermined number of game balls to the supply tray 14 under the control of the control board 3.
The set value operation unit 68 is for changing a set value for setting the winning combination probability of the bonus combination in six stages by using the setting key 680.

  As shown in FIGS. 1 and 2, the control board 3 includes a CPU 31, a ROM 33 and a RAM 34 as memory means, and an I / O unit 32 as an input / output interface. The CPU 31 executes a software program stored in the ROM 33, thereby generating a random number generating means 48 for generating a random number, a winning combination determining means 49 for determining a winning combination, a reel control means 45 for controlling the reel driving unit 51, an internal winning combination Each of an internal lottery means 42 for lottering, a pre-taken ball number determining means 44 for determining the number of balls to be pre-taken by lottery, and a take-in control means 43 for controlling a game ball taking-in operation by the ball take-in unit It is configured to realize the function.

  As shown in FIG. 1, the ROM 33 stores a winning random number table used for the lottery of the internal winning combination and a fetching ball number lottery table used for the lottery of the number of pre-taken balls. The winning random number table defines a range of random numbers for each internal winning combination to win. The pre-taken ball number lottery table defines a range of random numbers for selecting the number of pre-taken balls of 0, 5, and 15 according to the type of the internal winning flag.

  As shown in FIG. 1, the random number generation means 48 is a means for generating a random number by an internal calculation of the CPU 31. The random number generation means 48 of this example is configured to generate a random number using the fluctuation start signal of the start lever 62 as a trigger signal and input it to the internal lottery means 42 and the pre-taken ball number determination means 44. Note that the random number generation means 48 of this example individually generates a random number for the winning random number table and a random number for the take-in number lottery table.

  As shown in FIG. 1, the internal lottery means 42 determines an internal winning combination with reference to the winning random number table based on the random number generated by the random number generating means 48, and turns on an internal winning flag corresponding to the internal winning combination. Set to (1). The winning combination with the internal winning flag set to 1 is the winning combination. As shown in FIG. 3, the internal winning combination that the internal lottery means 42 of this example draws is 7 types of combinations: BIG bonus, REG bonus, 15-piece combination, 12-sheet combination, 8-sheet combination, 9-sheet combination, and replay combination. It is.

  The internal winning probability of each combination in the slot machine 1 of this example is set as shown in FIGS. That is, as shown in FIG. 5, the internal winning probabilities of the BIG bonus (indicated by BB in the figure) and the regular bonus (indicated by RB in the figure) are set by using the set value operation unit 68 described above. It is changed and set for each set value of ˜6. Further, as shown in FIG. 6, the internal winning probability of the small combination excluding the bonus combination is constant regardless of the set value. Furthermore, the small role flag that is an internal winning flag such as a small role disappears at the end of the game regardless of whether or not a prize has been won, and the bonus flag that is a winning flag for a bonus role is carried over to the next game until winning. . Therefore, if a small role or the like is not won in the internal winning game, it is a so-called missed game.

  As shown in FIGS. 1 and 2, the reel control means 45 starts the symbol fluctuation of the reel 2 in response to the fluctuation start signal and stops the symbol fluctuation of the reel 2 in response to the fluctuation stop signal. It is. The reel control means 45 inputs a control pulse to the stepping motor constituting the reel driving unit 51 and rotates the stepping motor by one step for each pulse. The reel control unit 45 counts the number of control pulses input to the reel driving unit 51, that is, the number of steps rotated by the stepping motor. In particular, in this example, the number of steps generated after the latest detection signal is counted by resetting the number of steps to zero each time the detection signal of the reference position piece of each reel 2 is captured.

  As shown in FIG. 1, the reel control means 45 performs so-called pull-in control in which symbols within a predetermined pull-in range determined by rules (rules for game machine certification and type verification, etc.) are stopped on the winning line. . Specifically, the reel control means 45 takes in the number of control pulses input to the reel drive unit 51, that is, the number of steps of the stepping motor, using the fluctuation stop signal as a trigger signal. Then, based on the number of steps, the Vita symbol which is the symbol 20 instantaneously positioned on the winning lines 211 to 215 is calculated, and the four symbols 20 following the Vita symbol at the head are within the predetermined pull-in range. Set as the symbol.

  As shown in FIG. 1, the reel control means 45 performs so-called pull-in control in which, if there is a role symbol corresponding to the internal winning flag within the predetermined pull-in range, the role symbol is stopped on the winning line. On the other hand, when there is no winning symbol within the predetermined drawing range, the reel control means 45 pulls the lost symbol onto the winning line and stops it so as to avoid winning of another winning combination for which the internal winning flag is not established. . As the pull-in control by the reel control means 45, in addition to the control method as described above, another control method using a stop pattern table can be adopted.

  As shown in FIG. 1, the winning combination determining means 49 is configured to control the reel control means 45 for each stepping motor (reel drive unit 51) corresponding to each reel 2L, 2C, 2R after the reels 2L, 2C, 2R are stopped. The number of steps counted by is taken in. Then, the winning combination determining means 49 obtains the type of the symbol 20 stopped on the winning lines 211 to 215 and determines whether or not a winning combination is established for the combination of the symbols 20.

  As shown in FIGS. 1 and 2, the pre-acquisition ball number determination means 44 refers to the above-mentioned intake ball number lottery table based on the random number generated by the random number generation means 48 and determines the pre-acquisition ball number by lottery. It is means to do. The pre-acquisition ball number determination means 44 of this example selects one of the three types of pre-acquisition balls of 0, 5, and 15 by lottery. Specifically, as shown in FIG. 7, the selection rate of each pre-acquisition ball number is set according to the type of the internal winning flag. It should be noted that, for each combination including a deviation other than the combination presented in the figure, 15 pre-loading balls are selected at a selection rate of 100%.

  Next, the flow of the ball take-in process in the slot machine 1 configured as described above will be described with reference to the flowchart shown in FIG. Note that the ball take-in process shown in FIG. 8 does not correspond to the operation of the bet button 64 after the end of the previous game and before the start of the subsequent game. This ball take-in process relates to a process of taking in advance game balls to be used for a later game during an execution period of a previous game among temporally continuous games.

  Here, first, as in step S101, it is determined whether or not the reel 2 has been started. When the reel 2 is started, it is determined whether or not the bonus flag which is the internal winning flag of the bonus combination has been announced as in step S102. If the bonus flag has not been announced, the internal winning flag is checked as in step S103.

  Then, the number of pre-taken balls is determined by lottery according to the internal winning flag as in step S104 (see FIG. 7), and the game balls having the pre-taken number of balls determined as in step S105 are captured. In this example, the processes of steps S102 to S105 are continuously performed. Therefore, in the slot machine 1 of this example, a case where a game ball used for a later game is taken in after the reel 2 is started may occur. That is, in the slot machine 1, the pre-take-in timing, which is the timing for taking in the game balls in advance, is set to the timing after the reel 2 is started.

The number of balls acquired in step S105 is displayed on the above-mentioned number of balls display portion 115 (see FIG. 2) as in step S106. Thereafter, the number of bet balls is subtracted from the number of taken balls in accordance with the operation of the bet button 64 as in step S107. Here, the remaining number of captured balls after subtracting the number of bet balls is displayed as it is on the captured ball number display unit 115, and the number of bet balls is displayed on the bet ball number display unit 114.
On the other hand, when the bonus flag has been announced (step S102), 5 balls, which is the minimum bet number, are taken in as in step S123.

  Thereafter, after all the reels 2 are stopped as in step S112, it is determined whether or not a bonus is won as in step S113. If a bonus is awarded and the number of balls taken in is 0 or 5 as in step S114, additional game balls are added so that the number of balls taken in by the ball take-in portion 56 is 15. Into.

  As described above, according to the slot machine 1 of this example, speedy game progress can be achieved by pre-fetching game balls. Furthermore, according to this slot machine 1, the internal winning flag can be predicted based on the number of balls taken in advance, and the player can feel a higher interest in the game.

  In addition, as long as the prior acquisition timing which takes in a game ball in advance is during the implementation period of the previous game, it may be any timing. Instead of the pre-take-in timing immediately after starting the reel 2 of this example, various pre-take-in timings can be set, such as after the first reel is stopped and after the second reel is stopped.

  Furthermore, as the pre-take-in timing when taking 15 balls corresponding to the maximum bet number, a plurality of timings such as setting a pattern of taking 5 balls each time the stop button is pressed can be set. When setting the pre-fetching timing as a pattern that captures five balls each time the stop button is pressed, each reel stops according to the symbols displayed on the reels and the number of balls captured. Each time you do it, you can step up the player's expectations.

  Further, the pre-take-in timing, which is the pre-take-in timing of the game balls, may be determined by lottery according to the internal winning flag as in the case of the pre-take-in balls. In this case, the pre-take-in timing changes according to the internal winning flag. Since the player can estimate the internal winning flag according to the pre-take-in timing, the interest of the game is further enhanced.
