BACKGROUND OF THE INVENTION
  The present invention is advantageous to a player when a predetermined symbol matching game is executed when a ball launched on the game board surface wins a specific winning opening, and as a result of the execution, a hit state where specific symbols are aligned appears. The present invention relates to a gaming machine that gives special value.
[0002]
[Prior art]
  As a game machine such as a pachinko machine that has been used in the past, when a ball wins a specific winning opening provided on the surface of the game board, a symbol matching game such as number matching is executed on the liquid crystal display, and the execution result There is a so-called Fever machine that generates a special value that is advantageous to the player when a state where specific symbols such as “777” are displayed.
[0003]
  A fever machine usually includes a so-called small digital circuit composed of 7-segment LEDs and the like in addition to a liquid crystal display (so-called main digital) for executing a symbol matching game. When a ball passes through a specific area (through chucker) on the game board surface, a number on the small digital is variably displayed for about 10 to 15 seconds, and then a certain number is confirmed and displayed.
[0004]
  Then, when a specific number such as “7” is finally displayed, the variable winning opening arranged near the out opening is opened to pick up a ball to enter the out opening and about 6 to 13 balls are picked up. The prize ball is paid out. Normally, the variable winning opening is closed when one ball to be entered into the out opening has been picked up.
[0005]
  In such a gaming machine, when a hit with a specific symbol occurs in the symbol matching game, the probability of hitting in the symbol matching game is set higher than the normal state until the next hit. There is a so-called probability machine with a probability variation function.
[0006]
  In general, the probability machine also activates a time reduction function that shortens the variable display period on a small digital, which is normally set from 10 seconds to 15 seconds, from 1 second to 2 seconds when a hit by a specific symbol appears. . Furthermore, when the hit that occurred during the operation of the probability variation function is again due to a specific design, the probability variation function and the time shortening function are continuously operated until another occurrence appears. .
[0007]
  With these functions, a situation in which wins are likely to appear continuously in the symbol matching game is formed, and a big privilege is given to the player.
[0008]
[Problems to be solved by the invention]
  In a conventional gaming machine, the probability variation function or the like is activated when a hit by a specific symbol is made, so when the reach state that becomes a hit is formed when another predetermined symbol is aligned, the reach state is It is easily determined by the player whether or not the benefits such as probability fluctuation can be obtained.
[0009]
  For this reason, the game content of the pattern matching game is not thrilling, and even if a reach condition occurs, it does not lead to benefits such as probability fluctuation, etc., sufficiently arousing the player's gambling and expectation There was a problem that could not be done.
[0010]
  Further, whether or not the transitioned probability variation state continues once more depends on the symbol displayed on the liquid crystal display, so when a reach state other than the specific symbol appears, thereafter, There was a problem that the player could not be given an expectation for the continuation of the probability variation state, and could not give the player enough thrill and excitement until the final stage of the symbol matching game.
[0011]
  The present invention has been made paying attention to such problems of the conventional technology, and provides a gaming machine that can sufficiently arouse the player's expectation for the benefit acquisition such as probability variation. It is aimed.
[0012]
[Means for Solving the Problems]
  In order to achieve this object, the gist of the present invention is as follows.SectionExists in the invention.
[1] When a predetermined symbol matching game is executed when a ball launched on the game board surface (11) wins a specific winning opening (12), and a hit state in which specific symbols are aligned appears as a result of the execution In a gaming machine (10) that gives a special value advantageous to a player,
  Main variable display means (20) for displaying the symbol matching game;
  Any of a normal probability mode in which the probability of winning per win is set to a normal value and a probability variation mode in which the probability of appearing per win is set higher when the ball wins the specific winning opening (12) A symbol matching game execution means (70) for executing the symbol matching game in the operation mode;
  Sub-variable display means (30) for displaying a screen game in which the execution result is confirmed and displayed after the lapse of a predetermined variable display period from the start of execution
  When a ball launched on the game board surface (11) wins a specific start opening, a normal mode in which the length of the variable display period is set to a normal value, and the length of the variable display period is the normal mode. Screen game execution means (80) for executing the screen game in any one of the shortened time-saving modes;
  In the symbol matching game performed when the operation mode of the screen game execution means (80) is not set to the time reduction mode, the operation mode of the symbol matching game is changed to the probability variation mode when the hit state appears. Probability change lottery means (91) for randomly drawing whether or not to shift to,
  A time reduction mode setting means (110) for changing the operation mode of the screen game to the time reduction mode when the operation mode of the symbol combination game is changed to the probability variation mode;
  When the winning state appears in the symbol matching game executed on the main variable display means (20) during the period in which the hourly mode is set, the symbol matching game has shifted to the hourly mode. If it is a predetermined number of symbol combination games, the probability variation mode is continued. On the other hand, if the symbol combination game is not a predetermined number of symbol combination games after the transition to the time-saving mode, the probability variation mode is canceled. The operation mode is returned to the normal mode and the normal probability mode, respectively.A gaming machine (10) characterized by that.
[0013]
  The present invention operates as follows.
  The symbol matching game execution means (70) includes a normal probability mode in which a probability of winning is set to a normal value when a ball wins a specific winning opening, and a probability variation in which the probability of hitting is set higher than that. When the symbol matching game is executed in any one of the operation modes, the screen game execution means (80) sets the length of the variable display period to the normal value when the ball wins a specific starting point. In any one of the normal mode and the time-saving mode in which the length of the variable display period is shortened from the normal value, the execution result is confirmed and displayed after a predetermined variable display period has elapsed since the start of execution. Run a screen game.
[0014]
  Probability transition lottery means (91), when a winning state appears in the symbol matching game performed when the operation mode of the screen game is not set to the time reduction mode,Shift the motion mode of the pattern matching game to the probability variation modeWhether or not the time reduction mode setting means (110) shifts the operation mode of the screen game to the time reduction mode when the operation mode of the symbol matching game shifts to the probability variation mode.
[0015]
  Then, when a winning state appears in the symbol matching game during the time setting mode, if the symbol matching game is the symbol matching game for a predetermined number of times after the symbol matching game has shifted to the time saving mode, the probability variation mode is continued. On the other hand, if the symbol matching game is not the symbol matching game of the predetermined number of times after the transition to the time-saving mode, the probability variation mode is canceled and the operation mode is returned to the normal mode and the normal probability mode, respectively. By doing so, when winning in the symbol matching game, it is decided whether to shift to the probability variation mode by performing random lottery, so the transition to the probability variation mode is caused by the appearance of a specific symbol As in the case where it is performed, the player is not discriminated whether or not to shift to the probability variation mode at an early stage of the symbol matching game. In addition, whether to continue the probability variation mode further depends on how many times the symbol matching game is executed after shifting to the short-time mode, not the symbols that appear, so Regardless of the symbol, the probability variation mode will continue until all symbols are finalized.It can arouse the player's expectation for.

The symbol matching game executing means 70 includes a random lottery unit 71 that executes a random lottery when a winning of a ball is detected by the winning detection switch 13. The lottery results of the random lottery section 71 are prepared in three types: winning, unreaching, and losing. The execution result of the symbol matching game is displayed according to the lottery result performed by the random lottery unit 71.
[0032]
  Of the three types of lottery results, winning corresponds to the case where a state in which numbers are aligned such as “777” is displayed as an execution result in the symbol matching game developed on the main variable display means 20. Reach miss is a symbol matching game on the main variable display means 20, for example, "77 ~", and when there is one more predetermined symbol at the place of "~", it comes off via the reach state that hits Corresponds to the case. In addition, detachment corresponds to a case in which the detachment symbol is confirmed and displayed without going through the reach state.
[0033]
  The through chucker 40 is a mechanical switch that is pressed by the ball when the ball passes. In addition to this, a magnetic sensor or an optical sensor can be used as the through chucker 40.

Further, the screen game execution means 80 includes an opening / closing control unit 82 that controls opening / closing of the variable prize opening 15.
[0035]
  The probability variation mode setting means 90 is a circuit portion that switches the winning probability in the symbol matching game executed by the symbol matching game executing means 70 from the normal probability mode to the probability variation mode. The probability variation mode setting means 90 has a random lottery unit 91 for randomly selecting whether or not to shift to the probability variation mode. A random lottery is performed by the random lottery unit 91 when a win occurs in a symbol matching game executed during a period other than the short-time mode.
[0036]
  The probability variation mode canceling means 100 is a circuit portion that cancels the probability variation mode set by the probability variation mode setting means 90 and sets the operation mode of the symbol matching game to the normal probability mode. The random lottery unit 71 of the symbol matching game executing means 70 executes a random lottery with a winning probability according to the operation mode set by the probability variation mode setting means 90 or the probability variation mode canceling means 100. ing.
[0037]
  The time reduction mode setting means 110 is a circuit part for setting the operation mode of the screen game performed by the screen game execution means 80 to the time reduction mode. When the probability variation mode is set by the probability variation mode setting means 90, the time reduction mode is set at the same time. The mode is set. The time reduction mode canceling unit 120 is a circuit part that cancels the time reduction mode set by the time reduction mode setting unit 110 and returns the operation mode of the screen game to the normal mode.
[0038]
  The time reduction mode canceling unit 120 counts the number of executions of the symbol matching game executed after shifting to the time reduction mode, and the symbol executed when the count value of the execution number counting unit 121 is a predetermined value. Reach state forming means 122 for sending an instruction to display the execution result via the reach state in the matching game to the symbol matching game executing means 70 is provided.
[0039]
  The reach state forming means 122 forcibly generates a reach state every time the count value of the execution number counting unit 121 increases by 10, that is, in the symbol matching game corresponding to the number of times that is a multiple of 10 after shifting to the time reduction mode. . When the reach state compulsorily generated by the reach state forming means 122 finally becomes a win, the time reduction mode is canceled. The probability variation mode canceling means 100 is configured to cancel the probability variation mode when the time reduction mode is cancelled.
[0040]
  The count value display section 51 of the continuation chance display section 50 always displays the count value of the execution count counting section 121, and the display lamp 52 blinks when the reach state is formed by the reach state forming means 122, and this reach In the event that is turned into a win, the player is notified that the probability variation mode will be continued.
[0041]
  The prize ball payout means 130 is a circuit part for sending an instruction to pay out a certain number of prize balls to a prize ball payout mechanism unit (not shown) when a ball wins the variable prize opening 15 or the like. The prize ball payout mechanism unit pays out the prize balls from a storage tank (not shown) to an upper plate provided in front of the gaming machine 10 based on an instruction from the prize ball payout means 130.
[0042]
  The special value generating means 60 is a large prize opening that is opened and closed when the random lottery result performed by the random lottery unit 71 is a win and the execution result is confirmed and displayed on the main variable display means 20. The attacker 61 and a solenoid 62 that opens and closes the attacker 61 are configured. The special value generating means 60 is set to repeat the operation of closing the attacker 61 for a short period of time (about 2 seconds) after opening it for a certain period (for example, 29 seconds) when the hit occurs.
[0043]
  The symbol matching game execution means 70, the screen game execution means 80, the probability variation mode setting means 90, the probability variation mode release means 100, the time reduction mode setting means 110, the time reduction mode release means 120, etc. are central to various controls in the gaming machine 10. A CPU (Central Processing Unit) that fulfills functions, a ROM (Read Only Memory), and a RAM (Random Access Memory) are used as main components.
[0044]
  In the ROM, various fixed data such as a program executed by the CPU and a symbol pattern displayed on the main variable display means 20 are stored. The RAM is a working memory for storing data temporarily required for executing the program.
[0045]
  Next, an operation flow in the gaming machine 10 will be described.
  3 and 4 show a flow of operations performed by the gaming machine 10 when a ball wins a specific winning opening 12. When a ball wins the specific winning opening 12 (step S201; Y), it is checked whether or not it is currently set to the time-saving mode (step S202).
[0046]
  When in the time reduction mode (step S202; Y), the count value of the execution number counting unit 121 is incremented by “1”, and the number of executions of the symbol matching game after shifting to the time reduction mode is counted (step S203). Further, when the number of executions after the shift to the time-saving mode is a multiple of N (N is a positive integer, here 10) (step S204; Y), the reach state forming means 122 is compared with the symbol matching game executing means 70 this time. An instruction to generate a reach state in the symbol matching game is sent (step S205). Further, the player is notified by blinking the display lamp 52 that the symbol matching game executed this time corresponds to the number of times the reach state is formed that leads to the continuation of the probability variation mode (step S206). .
[0047]
  Thereafter, the execution of the symbol matching game is started (step S207), and after a scroll period of about 30 seconds, the symbol as the execution result is fixedly displayed. The execution result of the symbol matching game is determined by a random lottery performed by the random lottery unit 71 when a ball wins the specific winning slot 12.
[0048]
  When not in the time reduction mode (step S202; N), the symbol matching game is immediately executed without performing processing such as addition of the number of executions (steps S203 to S206). When the execution result of the symbol matching game is out (step S208; N), as long as the game is continued (step S209; N), the process returns to step S201 again and waits for the ball to win the specific winning opening 12 To do.
[0049]
  When a win occurs in the symbol matching game (step S209; Y), it is checked again whether or not the time reduction mode is in effect (FIG. 4, step S210). When not in the time reduction mode (step S210; N), since the operation mode of the symbol matching game is set to the normal probability mode, the random lottery unit 91 of the probability variation mode setting means 90 sets the operation mode to the probability variation mode. A random lottery for determining whether or not to shift to (probability change mode) is executed (step S211).
[0050]
  When the random lottery performed by the random lottery unit 91 wins (step S212; Y), the probability variation mode setting means 90 changes the operation mode to the probability variation mode for the symbol matching game execution means 70. Send an instruction to do so. The probability variation mode canceling means 100 instructs the screen game execution means to set the operation mode of the screen game to the time reduction mode when the operation mode of the symbol matching game shifts to the probability variation mode (probability variation mode). The data is sent to 80 (step S213). Further, when the mode is shifted to the time reduction mode, the count value of the execution number counting unit 121 is initialized to “0” (step S214). Thereby, the number of times of the symbol matching game executed after shifting to the time reduction mode is counted by the execution number counting unit 121.
[0051]
  When the winning occurs in the time reduction mode (step S210; Y), it is checked whether or not the count value of the execution count counter 121 is a multiple of N (here, 10) (step S217). If it is not a multiple of N (step S217; N), the time reduction mode and the probability variation mode (probability variation mode) are canceled, and the operation mode is returned to the normal mode and the normal probability mode, respectively (step S218).
[0052]
  On the other hand, when the winning symbol matching game corresponds to the number of times that is a multiple of N after shifting to the time-saving mode (step S217; Y), the time-saving mode and the probability variation mode (probability variation mode) The mode is further continued without releasing (step S219).
[0053]
  Thereafter, the attacker 61 of the special value generating means 60 is opened and closed for 16 rounds to give the player a special value. When the game is not finished (step S216; N), the process returns to step S201 again and waits for the ball to win the specific winning opening 12. Note that special value generation (step S215) may be performed when a win occurs in the symbol matching game (immediately after step S208), and the process may proceed to step S210 after the opening / closing operation of the attacker 61 is completed. .
  In this way, when winning in the symbol matching game, whether or not to shift to the probability variation mode by random lottery is selected, so whether or not the player shifts to the probability variation mode based on the displayed symbol Can not be discriminated, and each time the reach state appears, the thrill and excitement that the transition to the probability variation mode may occur.
[0054]
  Further, when the mode is shifted to the probability variation mode, the time reduction mode is set at the same time, and the reach state is forcibly generated every N times (here, 10 times) after the shift to the time reduction mode. When a win is made, the probability variation mode is continued further, so that the player can enjoy the game of matching the number of times with the expectation to continue the probability variation mode, and thrill and excitement. You can taste it.
[0055]
  FIG. 5 shows a flow of operations performed by the gaming machine 10 when the ball passes through the through chucker 40. When the through chucker 40 detects the passage of the ball (step S301; Y), the random lottery unit 81 executes a random lottery (step S302).
[0056]
  Thereafter, it is checked whether or not it is currently in the time reduction mode (step S303). If it is in the time reduction mode (step S303; Y), after the symbols on the sub-variable display means 30 are variably displayed for 1 second, A number corresponding to the result of the random lottery performed first is confirmed and displayed (step S304).
[0057]
  In other words, when the lottery result of random lottery is a win, it is displayed variably for 1 to 2 seconds, and then the number “7” is fixedly displayed, and when the lottery result is off, the number other than “7” is fixedly displayed. To do.
[0058]
  On the other hand, when the mode is not the time reduction mode (step S303; N), the number corresponding to the current lottery result is fixedly displayed after the number is variably displayed over 10 to 15 seconds on the sub-variable display means 30 (step S303; N). S305).
[0059]
  When a number (here, “7”) corresponding to the small hit comes out when the number is fixedly displayed on the sub-variable display means 30 (step S306; Y), the variable winning opening 15 is opened (step S307). When one ball has won the variable winning opening 15 (step S308; Y), the variable winning opening 15 is closed and about 6 to 13 winning balls are paid out (step S309).
[0060]
  Thus, during the time reduction mode, the execution result is fixedly displayed on the sub-variable display means 30 in a short time after passing through the through chucker 40, so that the number of times the screen game is executed per unit time increases, Small hits will appear, and ball holding will be improved. That is, when the probability variation mode is entered, the time reduction mode is set in parallel with this, so that the ball holding in the probability variation mode is improved.
[0061]
  In the embodiment described above, the probability variation mode is further continued when the symbol matching game executed at the number of times corresponding to a multiple of 10 is made after the transition to the short-time mode. If it depends on the subsequent number of times, the number of times is not limited to a multiple of 10. For example, the odd number or even number of times, and how many times it is to be performed may be randomly selected every time the mode is shifted to the time-saving mode.
[0062]
  In addition to the above, in the embodiment, the symbol matching game developed as a slot machine on the variable display means 20 is developed. However, it may be a symbol matching game in which other symbols such as fish and fruit are aligned.
[0063]
【The invention's effect】
  According to the gaming machine according to the present invention,When winning in the symbol matching game, a random lottery is performed to determine whether or not to shift to the probability variation mode, so that when the transition to the probability variation mode is performed due to the appearance of a specific symbol, The player is not discriminated whether or not there is a transition to the probability variation mode at an early stage of the symbol matching game. In addition, whether to continue the probability variation mode further depends on how many times the symbol matching game is executed after shifting to the short-time mode, not the symbols that appear, so In any case, no matter what the reach state occurs, the probability variation mode will continue until all symbols are finally finalized.It can arouse the player's expectation.
