Description

This invention executes a special symbol lottery triggered by the game ball entering the starting port, informs the result of the special symbol lottery by the symbol variation pattern effect, and when the result of the special symbol lottery is a win, The present invention relates to a pachinko gaming machine that generates a special gaming state in which a large winning opening is opened in a predetermined manner to obtain more winnings than a normal state.

A conventional pachinko gaming machine is equipped with a microcomputer when a game ball launched on a game board surface by a player's launch handle operation enters a specific start opening provided on the game board surface. An internal lottery process by random number acquisition is executed in the main control unit. The lottery result is notified to the player by a variable display composed of LEDs and liquid crystal units capable of variably displaying a plurality of types of symbols. The variable display is driven to three symbol display positions. After the symbols are variably displayed, if the lottery result is “big hit”, for example, the symbol “7” is displayed in a state where three symbols are arranged. As a result of the establishment of the “big hit”, a special gaming state is started in which a large winning opening provided on the board is opened a plurality of times in a predetermined manner, and a large number of game balls are continuously connected to the large winning opening with the mouth wide open. As a result, a large amount of prize balls are paid out to the player.

By the way, the internal lottery process obtains a random number generated inside the main control unit at the timing when a game ball enters the start opening and temporarily stores it in the RAM. When the symbol variation starts, the lottery table The system uses a method to check against the situation, so that “big hits” may occur in a short period of time, or there will be no “big hits” even if you play for a long time (in general, “ "). When falling into such a state, the player consumes a large number of balls and the game itself becomes monotonous, so that the willingness to play is lost. In particular, beginners tend to give up continuation of the game at an early stage if such a state where profits cannot be obtained in a humming state continues.

For this reason, if the number of symbol fluctuations is greater than or equal to the predetermined number of times after winning the “big hit” and before winning the next “big hit”, more winning holes will be opened when the “big hit” occurs. A plurality of proposals have been made to relieve a player who has fallen into a mali state by changing to an open mode in which a prize ball can be obtained and setting a special game state that is highly valuable to the player. (For example, see Patent Document 1)

JP 2003-230713 A

That is, the above pachinko gaming machine tries to compensate for the loss in the humming state by adding a privilege to the “big hit” generated at the end of the humming state. However, in a general pachinko gaming machine, since the probability of occurrence of “big hit” is set to a low probability of 1/300 to 1/500, for example, a “big hit” is generated when the player expects relief. If the game is continued until there is a risk that the humiliation state will be prolonged. In addition, even if a special gaming state with added value is obtained, since an upper limit is set for the purpose of suppressing gambling for gaming balls that can be acquired in one special gaming state, Depending on the length, salvation may be disappointing for the player and the desire to continue the game may be lost.

This invention has been made paying attention to the above-mentioned problem, and even if it falls into a humming state, it suppresses the decrease in game balls due to the occurrence of a “big hit”, and at the same time, it is a game that does not make you feel bored. The purpose is to provide a pachinko gaming machine that allows a player to enjoy a game for a long time by incorporating it.

The pachinko gaming machine according to claim 1 of the present invention provides a lottery means for executing a special symbol lottery when a game ball enters the start opening on the game board surface, and notifies the result of the special symbol lottery by a symbol variation effect. A symbol display unit to perform, a first hit that can be expected to have a large profit for the player when winning as a lottery result by the lottery means, and a second hit that has less profit than the first win for the player when winning In the pachinko gaming machine including the above, the lottery result by the lottery means is detected by the non-winning period detecting means for counting the number of symbol variations when the first winning is not won per the first and the non-winning period detecting means A game letter that is advantageous to the player on the condition that the number of symbol fluctuations made is equal to or greater than a set value and that the second winning combination is won by lottery by the lottery means. And a privilege game control means for shifting to.

The invention according to claim 2 is provided with a game control means for opening a large winning opening provided in the game board surface in a plurality of modes when the special symbol lottery result is a win, and the amount of profit when winning is It is determined by the difference in the opening mode of the big prize opening.

That is, “first win” here means a winning combination that can be expected to have a large profit for the player as a lottery result of the lottery means, and various embodiments can be made. This is realized by repeatedly opening and closing the winning opening over 15 rounds and opening the winning opening in a manner in which many winnings are obtained. The player can thereby obtain a large amount of prize balls.

In addition, the “second winning” is a collective term for a winning combination that has far less winnings than the first winning winning combination. For example, the special winning opening can be opened and closed twice. This includes “two rounds of big hits” for ending the gaming state, “two rounds of normal winnings” that are simply opened and closed twice without triggering the special gaming state, and the like.

The former “2-round jackpot” includes a “two-round jackpot” that triggers the special symbol draw probability to be several times to 10 times the normal draw probability after the jackpot game ends. “Two-round sudden short-and-a-time hits” etc., in which the electric tulip provided at the entrance of the starting port is opened in a predetermined manner after the opening of the opening, and the special symbol change interval is shortened and the special symbol lottery is executed at an early stage. include.

In addition, the “two round normal hit” means a winning combination that does not trigger the change of the special symbol lottery probability or the special drawing change time reduction, and the “two round big hit” that triggers the change of the gaming state. Sometimes called “small hits” to distinguish them.

The “non-winning period” means a period in which the “first win” is not won continuously until the next “first win” is won, after being won. Specifically, it refers to the number of times the special symbol is changed based on the game ball entering the starting port.

In the above-described configuration of the present invention, “lottery means”, “game control means”, “non-winning period detection means”, “privilege game control means” and the like are realized by a computer program stored in the ROM of the main control unit. It can also be realized by a dedicated hardware circuit.

In addition, the “gaming state advantageous to the player” generated by the privilege game control means, for example, by shortening the symbol variation time in the symbol display unit, thereby promoting the digestion of the reserved ball, and per unit time To make it possible to increase the number of lottery times, and to open and close the electric tulip arranged at the entrance of the start opening in a predetermined manner to make it easier for the game ball to win the start opening. Transition to the “electrical support mode” or a combination of both is included.

Furthermore, as an example of “a gaming state advantageous to the player”, for example, the special symbol lottery probability to be won for “first win” is changed to a higher probability than usual, or “winning second” is won. When the prize winning opening is opened longer than usual, or when the player wins the “first win” in the predetermined state, the predetermined payout corresponds to the case where the player wins the “first win”. The game includes a variety of special gaming states, such as giving a player an opportunity to challenge a game that can be expected from the prize ball.

In addition,
The non-winning period detecting means in the invention according to claim 3 is characterized in that the non-winning period detecting means counts the number of special symbol fluctuations in the symbol display section after the special game state set when winning per first is over. It has a configuration for detecting the length of the non-winning period.

Further, in the invention according to claim 4, the count value of the number of symbol fluctuations counted by the non-winning period detecting means is reset by the winning per the first, but it belongs to the big hit where the change of the gaming state occurs. Even if it is a winning combination, the count value is not reset in the case of a winning combination that cannot expect a large number of balls such as “2 round big hit” or “2 round normal hit”.

In the invention described in claim 5, the privilege game control means generates a privilege game state selected by lottery from among a plurality of privilege game states. Note that the plurality of privilege game states include not only the case where the amount of profit is different for each player, but also the case where the type and mode of the game are different.

In the invention of claim 6, the number of symbol fluctuations counted by the non-winning period detection means is selected from among a plurality of privilege game states with different benefits received by the player by the privilege game granting means. The bonus game state selected according to the size is created.

In the invention according to claim 7, the bonus game granting means combines either one or both of a short-time gaming state in which the symbol variation time in the symbol display unit is shortened and a gaming state in which a game ball is likely to enter the starting port. A game state was created.

In the invention described in claim 8, the bonus game control means has won the second winning by the lottery by the lottery means when the count value of the number of symbol fluctuations counted by the non-winning period detecting means is not less than a specified value. As a condition, it is allowed to enter a game ball into a specific winning area that triggers the occurrence of a bonus gaming state, but if the count value of the symbol variation number is less than a specified value, the game ball enters the specific winning area. The ball is disabled and no transition to the special gaming state is made.

According to the first aspect of the present invention, since the “second hit” is provided in addition to the “first hit”, there is no opportunity to win the “first hit”, resulting in a long-term failure. However, before winning the next “first hit”, if the “second hit” is won, the player can receive a payout of the game balls moderately, reducing the player's investment risk, It becomes easier for the player to continue the game. In addition, if the humiliation state that is not won in the “first win” continues for more than the specified number of symbol fluctuations, the winning state in the “second win” is used as a trigger to shift to a game state that is advantageous to the player. Therefore, the player's willingness to continue playing can be improved.

According to the second aspect of the present invention, it is possible to freely set the magnitude of the profit obtained by the player by opening the large winning opening provided on the game board surface in a plurality of modes by the game control means. In particular, it is possible to give a variety of benefits to the player by combining the number of times of opening the big prize opening and the opening time.

According to the third aspect of the present invention, whether or not the player is in a so-called hamari state is determined based on the number of symbol fluctuations in the symbol display section after the special gaming state set when the big hit is won. When the number of symbol fluctuations reaches a determination reference value (for example, 1000 times), it is determined that the player is in a stalemate state.

According to the fourth aspect of the present invention, the count value of the number of symbol fluctuations counted by the non-winning period detecting means is reset by winning the first hit. In the case of a winning role that can not expect a lot of balls, the count value is not reset, so even if it is won in the second state, it is advantageous for the player such as short time and electric support mode, etc. Therefore, even if the player falls into the stalemate state, the player can continue the game until winning the next first hit without reducing the ball.

According to the invention described in claim 5, since the bonus game state given to the player is selected by lottery, the game is not uniform and can be changed, and the player's interest in the game is further enhanced. Can be increased.

According to the sixth aspect of the present invention, the total number of symbol fluctuations counted by the non-winning period detecting means from among a plurality of benefit game states having different benefits received by the player due to the action of the benefit game giving means. A privileged gaming state with a large profit received by the player is selected according to the magnitude of the numerical value. As a result, the longer the Hamari period, the greater the compensation, so that the player can continue the game with peace of mind.

According to the seventh aspect of the invention, a game in which one or both of the short-time gaming state in which the symbol variation time in the symbol display unit is shortened by the bonus game giving means and the gaming state in which the game ball is likely to enter the start opening is combined. Since the state is generated, various game characteristics can be set as the bonus game.

According to the invention described in claim 8, the bonus game control means invalidates the game ball entering the specific winning area when the count value of the number of symbol fluctuations counted by the non-winning period detection means is less than a specified value. Since the transition to the award gaming state is not performed, if the number of humiliations has not reached the specified number of times, it is invalid to illegally open the large winning opening and enter the gaming ball into the V winning opening Since prize balls are not paid out, fraud can be prevented in advance.

FIG. 1 shows an embodiment of a pachinko gaming machine to which the present invention is applied. In the illustrated pachinko gaming machine, a gaming board 2 having a substantially circular gaming area shown in FIG. 2 is detachably attached to the front surface of the gaming board holding frame 1 constituting the main body of the gaming machine. The game board 2 is covered with a front door having a round window with a transparent glass plate attached to the front of the game area. The game area on the front surface of the game board 2 is provided with a starting member 11, a plurality of large winning ports 12, 13, an out port 14, a passing gate 15, a normal winning port 16, and the like in addition to a center role described later. In addition, a number of obstacle nails (not shown) are implanted. An upper plate 3, a lower plate 4, and a game ball launching handle 5 are provided on the front surface of the game board holding frame 1 below the game board 2, and speakers 7, 7 is arranged.

Prior to the start of the game, the upper plate 3 is for storing a plurality of game balls that are lent out from a table ball lending device arranged adjacent to the game machine, and the ball storage portion of the upper plate 3 is a ball launcher. It communicates with an intake port (not shown) for supplying a game ball. The upper plate 3 communicates with the prize ball discharge port 6 of the lower plate 4 inside the game board holding frame 1, and when the upper plate 3 is full, it is supplied from a prize ball payout device (not shown). The prize ball overflows from the upper plate 3 and is discharged from the discharge port 6 to the lower plate 4. The firing handle 5 adjusts the firing strength of a hitting portion (not shown) driven by a motor, and moves the game ball taken into the hitting portion from the inlet of the upper plate 3 to the game area on the front surface of the game board 2. It is for launching and is turned by the player's hand.

At the center position of the game board 2, a center accessory having an image display unit 10 made of a liquid crystal panel as shown in FIG. 2 is arranged, and a normal symbol is provided in the upper edge area of the image display unit 10. The display part 8 and the special symbol display part 9 are each arrange | positioned. Below the image display unit 10, a special symbol lottery trigger displayed on the special symbol display unit 9 and a start opening 11 serving as a symbol variation trigger are provided. A big prize opening 12 and a second big prize opening 13 are provided. In addition, an out port 14 is provided at the lowermost part of the game area of the game board 2 for taking in an out ball that has not won any winning port. Further, four normal winning holes 16 are provided in the lower half of the game area of the game board 2.

A plurality of types of symbols (for example, “O” and “X”, “red” and “green” block displays) are variably displayed on the normal symbol display unit 8 by liquid crystal display. On the other hand, the left side of the image display unit 10 is provided with a gate 15 through which a game ball falling along the board surface of the game board 2 can pass. The game ball passes through the gate 15, and a passage sensor (not shown) When detected, the normal symbol lottery of the normal symbol display unit 8 is executed, the symbol starts to change, and the normal symbol is stopped and displayed after a predetermined time has elapsed.

As a result, when red is stopped and displayed on the normal symbol display section 8, the opening and closing members 11a and 11b of the electric tulip provided at the entrance of the start port 11 are opened, and the game ball is likely to win the start port 11 It becomes. In addition, since the opening and closing members 11a and 11b are closed after a predetermined time (about 0.3 to 2 seconds) after the start port 11 is opened, only one game ball can pass through the entrance of the start port 11. It becomes the interval of.

On the left side of the normal symbol display portion 8, four first hold display portions 80a to 80d by liquid crystal display are provided. When a game ball passes through the gate 15 during the symbol variation display of the normal symbol display unit 8, the normal symbol lottery random number acquired for the passage of the game ball is stored in the RAM of the main control unit 30. The first hold display portions 80a to 80d are for displaying the number of symbols in the hold state in which the symbol lottery random numbers of the normal symbol display portion 8 are stored, and the upper limit number is set to four. Yes. The held normal symbol lottery random number hit determination and symbol variation display are sequentially executed after the symbol variation display of the normal symbol display unit 8 being executed is completed.

The special symbol display unit 9 is for notifying the player of the result of the special symbol lottery executed at the timing when the game ball enters the start port 11, and “1” ˜ The number “9” and the letters “A” to “F” are displayed, and the fact that they have not won the winning combination (missing) is displayed by the symbol “−”. In this embodiment, a case where three types of hits, “15 round big hits”, “2 round big hits”, and “2 round normal hits”, are set as examples. In the following description, the term “round” indicating the number of times the winning prize openings 12 and 13 are opened is abbreviated by the symbol “R”. For example, “15 round big hit” is expressed as “15R big hit”. To do.

The image display unit 10 displays the symbol corresponding to the presence / absence of winning and the type of winning per prize along with the background and the character image in correspondence with the lottery result of the special symbol lottery displayed on the special symbol display unit 9. The image display unit 10 has three symbol display areas 10a, 10b, and 10c arranged side by side in the horizontal direction, and each of the symbol display areas 10a, 10b, and 10c has a plurality of types of symbols (for example, numbers, characters, Symbol or the like) is variably displayed, and one of the symbols is stopped and displayed, and the lottery result is displayed by a combination of the three symbols.

When a game ball enters the start port 11, a predetermined number of prize balls (for example, three) are paid out to the upper plate 3 from the prize ball payout device, and the above-described multiple types of hits are made in the main control unit 30. A special symbol lottery will be held. In this special symbol lottery, a lottery random number generated is sampled, and whether or not a prize is won and the type of winning per prize are determined based on whether or not the random number value is within a predetermined numerical range. Note that this type of special symbol lottery method is well known, and detailed description thereof is omitted here.

When the special symbol lottery is performed, numbers “1” to “9”, characters “A” to “F”, and a symbol “−” are sequentially displayed in a varying state on the special symbol display unit 9. Is done. As a result of the lottery, when “15R big hit” or “2R big hit” is won, any number from “0” to “9” is won, and when “2R normal hit” is won, “A” to “F” When one of the characters "" is "off", one symbol "-" is displayed in a stopped state after a predetermined time.

On the other hand, on the image display unit 10, a plurality of types of symbols are displayed in a varying state simultaneously in the symbol display areas 10a, 10b, and 10c in conjunction with the symbol variation display of the special symbol display unit 9. When “15R big hit” is won by the lottery, symbols of the same number (for example, “7”, “7”, “7”) are stopped in the symbol display areas 10a, 10b, 10c according to a predetermined order after a predetermined time has passed. When “2R jackpot” is won, the symbols of the same number (for example, “2”, “2”, “2”, “9”, “9”, “9”) are displayed according to a predetermined order after a predetermined time has passed. The symbols are displayed in a stopped state in the symbol display areas 10a, 10b, and 10c.

Further, when “2R normal hit” is won by the lottery, the image display unit 10 displays the variation state, and then displays the same alphabetic characters (for example, “A”, “A”, “A”). It is displayed in a stopped state in each symbol display area 10a, 10b, 10c.

On the other hand, when the result of the lottery is “out of”, the image display unit 10 displays a combination of symbols different from the above-described winning symbols in a stopped state. Therefore, when the player sees the combination of symbols stopped and displayed in the three symbol display areas 10a, 10b, and 10c of the image display unit 10, whether the lottery result is “win” or “out” Can be recognized.

On the left side of the special symbol display unit 9, four second hold display units 90a to 90d are provided by liquid crystal display. When a game ball enters the starting port 11 during the big hit gaming state described later or during the symbol variation display of the special symbol display unit 9, whether or not a lottery random number is appropriate for the entered ball and the symbol variation of the special symbol display unit 9 are detected. Display is suspended. The second hold display portions 90a to 90d are for displaying the hold number, and the upper limit number is set to four times.

Each of the first grand prize winning port 12 and the second major prize winning port 13 arranged in the vertical direction below the starting port 11 has a horizontally long shape. Opening and closing plates 120 and 130 are provided in front opening portions of the first grand prize winning opening 12 and the second big winning prize opening 13 respectively so as to be openable and closable, and the first electromagnetic solenoid shown in FIG. 3 is electrically driven. Opening and closing operations are performed by the special winning opening driver 38 and the second special winning opening driver 39. Each of the opening / closing plates 120 and 130 normally closes each of the prize winning openings 12 and 13 in a state along the board surface of the game board 2, and prevents the game balls from entering the respective prize winning openings 12 and 13. However, by falling to the near side with a fulcrum provided in parallel with the lower edge, each of the large winning openings 12 and 13 is opened, and the falling game balls are received by the back surfaces of the respective opening and closing plates 120 and 130. Can easily enter the ball.

When game balls enter the first grand prize opening 12 and the second big prize opening 13, a predetermined number of prize balls are paid out. In this embodiment, 15 prize balls are paid out for each entered ball in both the first grand prize opening 12 and the second big prize opening 13.

The second grand prize opening 13 is opened only when a predetermined condition is met in the “2R regular hit” win, and the inside of the second big prize opening 13 is a general prize opening 13a, 13a and a special prize opening 13b (V zone). ). When a game ball enters the special winning opening 13b (V zone), a special gaming state advantageous to the player is executed in order to rescue the player who has fallen into the stubborn state. In this embodiment, a time-saving game can be executed 100 times as a privilege game. The short-time game is set so that the symbol display time on the special symbol display unit 9 is shorter than the normal game state, and the opening time of the opening and closing members 11a and 11b of the electric tulip provided at the entrance of the start port 11 is set to be extended. The game state to be played is shown.

When a short game is executed at this time, a larger number of game balls can be put into the start port 11 than in the normal game. be able to. In addition, lottery determination can be executed frequently even when a number of special symbol lottery random numbers are reserved due to entering the ball, increasing the chances of lottery, and the probability of winning within a unit time. Will increase.

In this embodiment, it is assumed that the short-time game can be executed 100 times as the bonus game state. However, the present invention is not limited to this. For example, after the “15R big hit” is won and the big hit game state ends, the “15R Until the “big hit” is reached, the probability of winning the “15R big hit” may be changed to a higher probability than in the normal game state. Further, by increasing the number of prize balls to be paid out for entering the second grand prize opening 13, or by extending the opening time of the second big prize opening 13 from the usual, more prize balls May be obtained.

When “15R big hit” is established, a special game state in which a winning ball is easily obtained is set. In the special gaming state, the first grand prize opening 12 is opened, and a predetermined number (for example, 10) of game balls enter the first big prize opening 12, or a predetermined time (for example, before a predetermined number of game balls enter) 30 seconds), the first big prize opening 12 is closed, and this cycle is taken as one round, and the opening operation of the first big prize opening 12 is continuously executed for 15 rounds. In this special game state, game balls enter the first big prize opening 12 one after another, and a large amount of prize balls are obtained.

On the other hand, when “2R normal hit” is established, the game state different from the “15R big hit” state (hereinafter referred to as “small hit game state” for convenience) is set. In the “2R normal hit” state, the first big winning opening 12 or the second big winning opening 13 is set to be opened instantaneously (for example, 0.5 seconds) twice, even if “15R big hit” is set. Even if it is not established, the player can enjoy the profit. Since the player can establish the “2R normal hit” set with a high probability of winning relatively frequently, the player can pay out the game ball appropriately while in the state of being in a state until “15R big hit” is established. Can receive.

Further, when the “2R big hit” is established, the gaming state is set different from the “15R big hit” state. In the “2R big hit” state, the first big prize opening 12 is opened twice instantaneously (for example, 0.5 seconds) in the same opening manner as the “small hit game state” in “2R normal hit”. Is set to the state. If “2R jackpot” is “2R probable jackpot”, the special symbol lottery probability is the normal lottery probability after the first big prize opening 12 is instantaneously opened twice and the special gaming state is ended. Therefore, the degree of expectation for “15R big hit” is greatly increased. Also, when “2R big hit” is “2R sudden short time big hit”, the first big winning opening 12 is instantaneously opened twice and the special gaming state is ended, and then the short time game is entered 100 times. In this way, when the player wins the “2R probable big hit” or “2R sudden short-time big hit”, the player cannot distinguish from the “2R normal big hit” because the opening / closing mode of the first big winning opening 12 is the same. Suddenly you will enter into a probable state or a short-time game, so you have high expectations for game development.

When the above-mentioned “2R normal hit” is won, the first big prize opening 12 and the second winning opening 12 and the second win are determined depending on whether or not a “15R big hit” cannot be achieved even if the player plays for a long time. The special winning opening 13 is selectively opened. When it is determined that the player has not fallen into the state, that is, when “15R jackpot” is won within the specified number of times, the first big winning opening 12 is instantaneously opened. On the other hand, if it is determined that the player has fallen into the state, the second grand prize opening 13 is instantaneously opened, and a game ball is placed in the special prize opening 13b (V zone) in the second big prize 13. Then, the time-short game is executed 100 times. Thereby, even if the player falls into a stalemate state, the player's interest in the game can be enhanced.

Two normal winning openings 16 are arranged on both the left and right sides of the starting opening 11. When a game ball enters these normal winning openings 16, a predetermined number of winning balls (for example, 10 balls) are obtained. It is paid out to the upper plate 3. The game balls (out balls) that have not entered any of the start port 11, the first grand prize port 12, the second major prize port 13, and the normal prize port 16 are collected in the out port 14 at the bottom of the game board 2. The

FIG. 3 shows an electrical configuration of the pachinko gaming machine 1 described above. The control device of the pachinko machine game 1 includes a main control unit 30 for overall control of the progress of the game, a sub-control unit 40 for performing image display control, and a sub-control in charge of lighting lamp control and sound output. It is comprised with the control part 50. FIG. The main control unit 30 and the sub control units 40 and 50 are connected by a harness via the relay board 35.

The main control unit 30 is composed of a microcomputer and includes a CPU 31, a ROM 32, a RAM 33, and the like. The main control unit 30 includes a random number generator (not shown), and the CPU 31 samples a lottery random number generated by the random number generator when a game ball enters the start port 11, and compares the sampled lottery random number with the lottery table. Then, it is determined whether or not it is correct. The ROM 32 stores a lottery determination table for lottery related to winning in addition to a program for controlling the progress of the game. The RAM 33 is used to temporarily store the sampled lottery random numbers and temporarily store data necessary for advancing the game, such as a winning flag (numerical information for state storage) when winning in the lottery. It is done.

2, each of the start opening 11, the first grand prize opening 12, and the gate 15, and further, each ordinary winning opening 16, has a start opening sensor S1 for detecting the entrance and passage of a game ball, A first grand prize port sensor S2, a gate sensor S5, and normal prize port sensors S6 to S9 are provided. The second grand prize opening 13 includes a general prize opening sensor S3 for detecting a game ball that has entered the general prize opening 13a, 13a in the second big prize opening 13, and a second prize winning opening 13 A special prize opening sensor S4 for detecting a game ball that has entered the special prize opening 13b is provided. These sensors are connected to the main control unit 30 via the input / output port 34, and output signals from the sensors S1, S2, S3 and S4, S5, S6 to S9 are input to the main control unit 30. It has become.

Further, the normal symbol display unit 8, the special symbol display unit 9, the first reserved display units 80a to 80d, and the second reserved display units 90a to 90d are connected to the main control unit 30 through the driver circuit 36. The opening / closing members 11a and 11b of the starting opening 11, the opening / closing plates 120 and 130 for operating the opening / closing plates 120 and 130 of the first and second winning winning openings 13, respectively, A big prize opening drive unit 38 and a second big prize opening drive unit 39 are connected.

The RAM 33 of the main control unit 30 is provided with a symbol variation number storage unit 330 for storing the symbol variation number N of the special symbol display unit 9 while updating it. When the special symbol display unit 9 variably displays the special symbol, the CPU 31 adds “1” to the variation number N and updates the variation number N. The CPU 31 resets the number of fluctuations to “0” when “15R big hit” is won by the lottery. When the lottery result is “2R big hit”, “2R normal hit”, or “out of”, the CPU 31 does not reset the variation number N.

The RAM 33 is provided with a random number storage unit 331 for storing a lottery random number sampled for lottery. As shown in FIG. 4, the random number storage unit 331 includes an operation area 332 and first to fourth holding random number storage areas 333 to 336, and lottery random numbers are temporarily stored in the operation area 332 for lottery processing. In addition, in the first to fourth holding random number storage areas 333 to 336, lottery random numbers sampled at the time of entering the starting port 11 when the lottery random numbers are held are stored.

When the special symbol display unit 9 is not displaying the symbol variation or being in the big hit state, when a game ball enters the start port 11 with no lottery random numbers stored in the first to fourth reserved random number storage areas 333 to 336, The sampled lottery random number is temporarily stored in the operation area 332, and the lottery random number is used to check the result in order to determine the result.

On the other hand, when a game ball enters the start port 11 during the symbol variation display of the special symbol display unit 9 or the big hit state, the random numbers sampled at the time of entering the first to fourth reserved random number storage areas 333 to 333 336 sequentially stored. When the symbol variation display and the big hit state of the special symbol display unit 9 are finished, the random numbers stored in the first holding random number storage area 333 are read into the work area 332 and collated with the lottery table, and the second Each random number stored after the holding random number storage area 334 is moved to the previous random number storage area. When a game ball enters the start port 11 with the number of lotteries being held at the upper limit (four), no lottery random number is stored for the ball entering the start port 11.

The sub-control units 40 and 50 are constituted by a microcomputer and include CPUs 41 and 51, ROMs 42 and 52, and RAMs 43 and 53, respectively. The image display unit 10 is connected to one sub-control unit 40 via a driver circuit 44, and the speaker 8 and various effect lamps 17 are connected to the other sub-control unit 50 via a driver circuit 45.

The ROM 42 of the sub-control unit 40 stores image data necessary for the image display unit 10 to display symbols composed of numbers, characters, symbols, etc. one after another in a variable state or in a stopped state. ing. The CPU 41 of the sub-control unit 40 displays the images one after another in a varying state on the image display unit 10 based on the image data stored in the ROM 42, and then receives an effect command corresponding to the lottery result from the CPU 31 of the main control unit 30. When this is done, an effect image corresponding to the presence / absence of winning and the type of winning winning is displayed on the image display unit 10.

Although not illustrated in FIG. 3, in addition to the above, the driver circuit 36 is also connected with a firing motor of a hitting unit, a prize ball payout mechanism, and the like.

FIG. 5 is a flowchart for explaining the flow of control by the CPU 31 of the main control unit 30 for the operation of the pachinko gaming machine 1 configured as described above. In the figure, “ST” is an abbreviation for “STEP” (step).

In step ST <b> 1 of FIG. 5, the CPU 31 determines whether or not a game ball has entered the start opening 11 by detecting the presence or absence of an output signal from the start opening sensor S <b> 1. If the determination is “YES”, the process proceeds to step ST 2, and the CPU 31 determines whether or not the special symbol display unit 9 has a special symbol variation timing. When the symbol variation display is not held, when entering the starting port 11, when the symbol variation display is suspended, when the immediately preceding symbol variation display is completed or when the big hit state is terminated, step ST2 The determination is “YES”, and the process proceeds to step ST3. If it is not the timing for changing the symbol, the determination in step ST2 is “NO”, and the process waits until the timing for symbol variation is reached.

In the next step ST3, the CPU 31 determines the lottery result by comparing the random number stored in the operation area 332 of the RAM 33 with the lottery table. Further, the CPU 31 displays the numbers “0” to “9”, the characters “A” to “F”, and the symbol “−” one after another in a varying state on the special symbol display unit 9, and For the three symbol display areas 10a, 10b, and 10c, symbols are variably displayed in step ST4. Next, in step ST5, the CPU 31 adds 1 to the symbol variation count N stored in the symbol variation count storage section 330 of the RAM 33.

When the result of the lottery is “15R big hit” or “2R big hit”, the determination in step ST6 is “YES”, and the process proceeds to step ST7. In step ST7, it is determined whether or not the content of “big hit” is “2R big hit”. For example, in the case of “15R big hit”, the determination result is “NO”, so the process proceeds to step ST8, and the CPU 31 displays a special symbol display. The number 9 from “0” to “9” is displayed in the stopped state on the part 9 and the symbol related to “15R big hit” is displayed in the stopped state in each of the symbol display areas 10 a, 10 b, 10 c of the image display unit 10. Display them. Thereafter, the CPU 31 sets a special gaming state, that is, a state in which the first big prize opening 12 is opened for 15 rounds (step ST9). After the end of the special gaming state, the CPU 31 resets the symbol variation number N to 0 (step ST10), and ends the process for entering the starting port 11.

If the result of the special drawing lottery is not “15R big hit” or “2R big hit” but “2R normal hit” in step ST6, the determination in step ST6 is “NO”, and the process goes to step ST11. Since the determination in step ST11 is “YES”, the CPU 31 causes the special symbol display unit 9 to display any of the characters “A” to “F” in a stopped state and displays each image on the image display unit 10. Three symbols related to “2R normal hit” are displayed in the stopped state in the areas 10a, 10b, and 10c (step ST12).

Next, the CPU 31 determines whether or not the number N of changes in the special symbol is 1000 or more (step ST13). If the number of times of change N is 1000 or more, the determination in step ST13 is “YES”, and the CPU 31 determines that the player is in a stalemate and instantaneously sets the second big prize opening 13 to 2. Open 2 times to create a “2R normal hit state”. (Step ST14)

In the “2R normal hit state” of step ST14, when the game ball is successfully placed in the special winning opening 13b of the second large winning opening 13 while the second large winning opening 13 is open, step ST15 is performed. Is determined to be “YES”, and after the “2R normal hit state” is completed, the CPU 31 opens and closes the first big prize opening 12 twice in the same manner as the “2R sudden short hit big hit”, and thereafter The player is notified that the game will be entered (step ST16), the time-short game state is set (step ST17), and the time-short game is executed 100 times. At this time, the short game can suppress a significant decrease of the game balls even if the player falls into a stalemate state, and the probability of winning the “15R big hit” is increased by increasing the chance of lottery. Can improve interest in

However, if the game ball fails to enter the special winning opening 13b of the second large winning opening 13 while the second large winning opening 13 is opened in step ST14, the determination in step ST15 is It becomes "NO", and the process with respect to the entrance to the starting port 11 is complete | finished, without performing a time-saving game.

In addition, during the time-saving game, when “2R normal hit” is won again without winning “15R big hit”, the determination of step ST6 is “NO”, the determination of step ST11 is “YES”, and “2R normal hit” If a game ball enters the special winning opening 13b of the second big winning opening 13 during the “winning state”, the determination in step ST15 is “YES”, and the number of short-time games is reset to 100. In this way, when the game ball enters the special prize opening 13b of the second big prize opening 13 without winning the “15R jackpot”, the time-short game continues 100 times, so the time-short game is executed in a daisy chain. Opportunities for winning the “15R jackpot” will increase further.

In step ST13, if the number of changes N is less than 1000, the determination is “NO”, and the CPU 31 determines that the player has not fallen into the stubborn state. In step ST18, the first grand prize is won. It is set to “2R normal hit state” in which the mouth 12 is instantaneously opened twice. After the “2R normal hit state” is finished, the process for entering the starting port 11 is finished.

When the number of fluctuations N is less than 1000, the second big prize opening 13 is not opened. More specifically, when the number of fluctuations N is less than 1000, the opening / closing plate 130 of the second big prize opening 13 is locked and fluctuated by the action of a solenoid (not shown) that operates according to a command from the main control unit 30. When the number N is 1000 or more, the lock is released. In addition, if the number of fluctuations N is less than 1000 even if the opening / closing plate 130 is illegally opened and a game ball flows in, the detection signal transmitted from the general winning port sensor S3 and the special winning port sensor S4 is sent to the main control unit. Since 30 is not accepted and is programmed to be invalidated, it is possible to prevent an attacker opening goto act to the second big prize opening 13 when the number of times of humiliation is equal to or less than a predetermined number.

On the other hand, when the determination of the lottery result in step ST3 is “out of”, the determinations in step ST6 and step ST11 are both “NO”, and the CPU 31 displays the symbol “−” on the special symbol display unit 9. While displaying in a stopped state, the image display area 10a, 10b, 10c of the image display unit 10 displays a combination of misplaced symbols in a stopped state (step ST19), and the process for entering the starting port 11 is terminated. .

However, if “2R jackpot” is won in the determination of the lottery result in step ST3, the determination in step ST6 and the determination in step ST7 are both “YES”, so the CPU 31 displays a special symbol display in step ST20. The unit 9 displays any number of “0” to “9” corresponding to “2R big hit” in a stopped state, and “2R big hit” is displayed in each symbol display area 10a, 10b, 10c of the image display unit 10. Three related symbols are displayed in a stopped state. Thereafter, the CPU 31 sets a 2R big hit state, that is, a state where the first big prize opening 12 is instantaneously opened for two rounds (step ST21). After the end of the 2R big hit state, the CPU 31 sets the time-short game state in step ST17, executes the time-short game 100 times, and ends the processing for entering the starting hole 11 at the end of the time-short game.

In the embodiment of FIG. 5 described above, when the player cannot draw “15R big hit” and is in a stalemate, the game ball is placed in the special winning opening 13b (V zone) in the second large winning opening 13. However, instead of this, a control as shown in FIG. 6 may be performed.

In the embodiment of FIG. 6, the type of privilege to be given to the player when a game ball enters the special winning opening 13b (V zone) in the second large winning opening 13 is determined by lottery, and the lottery result is determined. A privilege gaming state occurs. As a privilege game to be given, in addition to being able to execute the short-time game 100 times, it is possible to shift to the 15R jackpot state with a predetermined probability (a winning probability lower than “15R jackpot”).

In the flowchart shown in FIG. 6, the basic processing flow is the same as that shown in FIG. 5. Steps ST101 to ST115 in FIG. 6 correspond to steps ST1 to ST15 in FIG. 5, and steps ST120 and ST121 are shown in FIG. This corresponds to steps ST18 and ST19 of FIG. Therefore, here, only the part different from the process of FIG. 5 will be described, and the description of the process flow of the overlapping part will be omitted.

That is, in the situation where “2R normal winning” is won and the process proceeds to step ST114 of the flowchart shown in FIG. 6, when the second big winning opening 13 is opened and the 2R normal winning state is entered, If a game ball enters the special winning opening 13b (V zone) in the big winning opening 13, the determination in step ST115 is "YES", and a special game type lottery given to the player is performed in step ST116. . As a result of the type lottery in step 116, if the bonus game state is a short-time game, the determination in step ST117 is “YES”, and the CPU 31 opens and closes the first big prize opening 12 instantaneously twice in step ST118. Then, after notifying the player of the entry into the time-saving game, the time-saving game is set in step ST119 and the time-saving game is executed 100 times.

On the other hand, if the hit type at step ST116 is “big hit game”, the determination at step ST117 is “NO”, and the CPU 31 proceeds to “15R big hit game state”, that is, proceeds to step ST109 to enter the first big prize. Set mouth 12 open for 15 rounds. After the end of the 15R big hit state, the CPU 31 resets the symbol variation number N to 0 in step ST110, and ends the process for entering the starting port 11.

When the determination result in step ST103 is “2R big hit”, the determinations in step ST106 and step ST107 are both “YES”, so the CPU 31 proceeds to the process in step ST122 and displays “2R in the special symbol display unit 9”. Any number from “0” to “9” corresponding to “big hit” is displayed in a stopped state, and symbols related to “2R big hit” are stopped in each symbol display area 10a, 10b, 10c of the image display unit 10. To display three. Thereafter, the CPU 31 sets the 2R big hit state, that is, the state where the first big winning opening 12 is instantaneously opened for two rounds in step ST123, and after the 2R big hit state ends, the process proceeds to step ST116.

In step ST116, as in the case of “2R normal hit” described above, a special game type lottery given to the player is performed. As a result of the type lottery in step 116, if the bonus game state is a short-time game, the determination in step ST117 is “YES”, and the CPU 31 opens and closes the first big prize opening 12 instantaneously twice in step ST118. Then, after notifying the player of the entry into the time-saving game, the time-saving game is set in step ST119 and the time-saving game is executed 100 times.

If the hit type at step ST116 is “big hit game”, the determination at step ST117 is “NO”, and the CPU 31 takes “15R big hit game state”, that is, the first big prize opening 12 for 15 rounds. It is set in a state where it is released by the amount (step ST109). After the end of the big hit state, the CPU 31 resets the symbol variation number N to 0 (step ST110), and ends the process for entering the starting port 11.

According to the embodiment of FIG. 6, since a privilege given to a player is selected by lottery, the game is not uniform, can be changed, and the player's interest in games can be further enhanced. it can.

In the above-described embodiment, when the number N of changes in the special symbol on the special symbol display unit 9 reaches the specified number of times after winning the jackpot and then winning the jackpot, the player is in a stalemate state. However, the present invention is not limited to this, and the game time until the next big win is measured after winning the big win is measured, and when the predetermined time has elapsed, the player enters the humming state. You may make it the structure which discriminate | determines that it has fallen.

Further, in the above-described embodiment, the determination reference value to be compared with the special symbol variation number N of the special symbol display unit 9 is fixed to 1000, but the embodiment of the pachinko gaming machine of the present invention is not limited to this. However, the determination reference value may be set by lottery.

FIG. 7 is an example of a lottery table used for the lottery. In this example, when “15R big hit” is won, the set determination reference value is reset and lottery is performed according to the selection rate as shown in FIG. The determination reference value selected by the lottery is compared with the number N of changes in the special symbol on the special symbol display unit 9 until the next “15R big hit” is won. As a result, the number of changes N exceeds the determination reference value. At this time, it is determined that the player has fallen into the stalemate state.

Further, as a further embodiment, when the number N of changes in the special symbol exceeds the determination reference value 1000, the magnitude of the benefit in the privilege gaming state is changed in stages according to the value exceeding the 1000 reference value. For example, every time over 100 times and 100 times are added, the number of time reductions may be added 10 times to 100 times, or the number of rounds may be increased by 1 in the case of 15R big hit state. Is possible. Of course, the determination reference value N in this case does not have to be a fixed type of 1000 times, and a determination reference value lottery with a selection rate shown in FIG. 7 may be used. That is, when the determination reference value is determined by lottery, the number of determination reference “so-called ceiling times” is displayed on the liquid crystal panel or the like, and the player determines whether to win the “second win” depending on how late Since the level of the profit received changes, the player is strongly interested in the lottery of the number of determination criteria, and can be motivated to continue the game even after the number of determination criteria.

Furthermore, in the above-described embodiment, a configuration example is shown in which the game board 2 is provided with two large winning ports, the first large winning port 12 and the second large winning port 13, but the present invention is not limited to such an embodiment. Instead, for example, as shown in FIG. 8, a configuration may be provided in which only one second large winning opening 13 including a general winning opening 13 a and a special winning opening 13 b (V zone) is provided. However, in this case, the function of executing a special game by entering the special prize opening 13b (V zone) as described above is effective only when the number of changes in the symbol is equal to or greater than the specified number, and the number of changes is less than the specified number. In that case, a function to be invalidated may be added.

The present invention is a pachinko gaming machine in which a lottery is executed on condition that a game ball enters the start opening on the board surface and is set in a special game state in which a winning ball is easily obtained when winning a big hit in the lottery. If so, the present invention can be applied to various pachinko machines such as a pachinko machine having a probability variation function in which the probability of winning a big hit in a game after the jackpot ends is set to a higher probability than usual or a pachinko machine having no such function.
