Abstract

<P>PROBLEM TO BE SOLVED: To prevent reduction of customers by effectively utilizing the function of suspension. <P>SOLUTION: Whether the function of suspension should be made effective or not, or whether the effectiveness of the function of suspension should be determined by a lottery or not is set by the operation of a slide switch. If it is determined to make the function of suspension effective, the function is effective after termination of a BB (Big Bonus) mode regardless of the set value, and the game in a slot machine can not be played. A player, considering that the function of suspension is effective, thinks that the set value is high in the slot machine and continues the play after the slot machine is reset. On the other hand, even if it is determined that the function of suspension should be canceled, the set value is still high in some cases, and therefore, the player can not give up the possibility that the set value in the slot machine is high if the function of suspension is not made effective after termination of the BB mode, and the player continues the play. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a gaming machine such as a slot machine that is installed and used in a game hall such as a pachinko parlor, and satisfies a preset condition such as when the BB (Big Bonus) mode is finished, for example. In this case, the present invention relates to a gaming machine having a so-called stop function that disables subsequent games.

  Slot machines that are installed and used in amusement halls such as pachinko parlors are called pachislot machines, and medals earned by playing games (games) are given a certain value to the medals that are the game media. Can be exchanged for various prizes. In such a slot machine, a plurality of winning tables having different lottery and lottery probabilities of a plurality of types of winning combinations are provided in advance, and one of these winning tables is used during the game. Each of these winning tables is assigned a setting value. By changing the setting value, the corresponding winning table is selected.

In the case of such a slot machine, in addition to being able to change the setting value described above, for example, when a game in the BB (Big Bonus) mode is completed, a so-called stop function that disables the subsequent game execution is effective. It can be set whether or not. For example, when the stop function is enabled, if the BB mode is ended, the subsequent game cannot be performed unless a return process is performed by a store clerk in the game hall, for example. Recently, whether or not to enable the stop function, when the stop function is enabled, when the above-described BB mode ends, when a predetermined number of medals to be paid out has been reached, or any of these It has been proposed to be able to set whether to enable the stop function in any of the cases where one of them is established (Patent Document 1). This is convenient because the stop function can be set by the game arcade where the slot machine is installed.
Japanese Patent Laid-Open No. 07-204316

  However, when the BB mode is finished or the payout number of medals reaches the set number, if the stop function becomes effective, the game store takes the lead, and the player performs the game with satisfaction. There is a problem that can not be. For example, in order to increase the operating rate of the slot machine installed in the amusement hall until a predetermined time after the game hall is opened, for example, “When the stop function is enabled at the end of the BB mode, the slot machine is set to a high setting. By flowing the information that “is” to the player, the player is expected to receive a lot of medals. However, if the player becomes an expert, the setting of the slot machine can be predicted by playing the game. Therefore, when the first BB mode ends, the game in the slot machine is stopped. As a result, there is a problem that it is easy for customers to leave, and the operating rate of the slot machine falls.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine that can prevent a customer from leaving by effectively using a stop function.

  In order to achieve the above object, the gaming machine of the present invention is a gaming machine having a normal gaming state in which a normal game is performed and a special gaming state in which a profit-giving value for the player is higher than that in the normal gaming state. When the game in the special gaming state is finished, the lottery means for determining whether to enable the so-called stop function, which disables the subsequent game, or the stop function is enabled In addition, an operation invalidation control unit that performs control to invalidate the operation in the game, and a release unit that cancels the control in the operation invalidation control unit by outputting a return signal are provided. The profit-giving value includes the number of net medals and the payout rate. Examples of the operation in the game include medal insertion operation, medal bet operation, start lever operation, stop button operation, and the like.

  A plurality of probability tables used by the stop lottery means; a selection operation unit operated when selecting any of the plurality of probability tables; and the plurality of probability tables based on an operation in the selection operation unit. Table selection means for selecting one probability table from the probability table.

  The selection operation unit may select whether or not to enable the stop function, in addition to selecting a probability table used for the stop lottery means.

  According to the gaming machine of the present invention, a gaming machine having a normal gaming state in which a normal game is performed and a special gaming state having a higher profit-giving value for the player than in the normal gaming state, the special gaming state When the game is finished, the lottery means for determining whether to enable the so-called stop function, which disables the subsequent game, by lottery, and the operation in the game when the stop function is enabled Since the operation invalidation control means for performing the invalidation control and the release means for releasing the control in the operation invalidation control means by outputting a return signal, the stop function is enabled after the special gaming state is finished. In this case, for example, even if the lottery probability at the time of the lottery of whether or not the game is won is set low, the player has set the lottery probability at the gaming machine high. With the idea, resulting in from would entertain the expectation for special game state the following, it can be difficult to the stand away from the gaming machine.

  On the other hand, even if the lottery probability at the time of the lottery in the game is set high, the stop function may not be effective, so the player will be the lottery probability at the time of the lottery whether or not the game is won Is set to be high, or since it is considered to play a little more games, as a result, it is possible to make it difficult to leave the gaming machine apart.

  A plurality of probability tables used by the stop lottery means; a selection operation unit operated when selecting any of the plurality of probability tables; and the plurality of probability tables based on an operation in the selection operation unit. Since the table selection means for selecting one probability table from the probability table is provided, the setting intended by the manager of the game hall can be performed.

  In addition to selecting the probability table used for the stop lottery means, the selection operation unit can select whether or not to enable the stop function, so that the stop function is actually effective. It is possible to prevent the player from knowing whether or not.

  The slot machine of the present invention has a normal mode (normal game state) and a BB (big bonus) mode (special game state) in which the payout rate is higher than that in the normal mode. The BB mode is composed of an RB introduction game using three medals and an RB mode game that is shifted by winning a JAC role in this RB introduction game, for example. The number of games of the RB introduction game is performed up to 30 times, for example. On the other hand, a game in the RB mode is a game using one medal, and the game in the RB mode is completed by, for example, performing 12 games or winning 8 times. In one BB mode game, the RB mode described above is performed up to three times. When the RB introduction game is performed 30 times or the RB mode is performed 3 times, the BB mode is ended. The game content in the BB mode is not necessarily limited to this. For example, when the RB mode is awarded in the RB introduction game and the RB mode game is performed and the RB mode game is performed, It is assumed that the BB mode game is terminated when the number of net increase medals obtained in the mode (the number of medals paid out-the number of medals inserted) reaches a preset number.

The overflow storage box 56 stores medals discharged from the storage tank 55 when the number of medals stored in the storage tank 55 of the hopper device 36 exceeds a predetermined amount.

  FIG. 4 is a functional block diagram showing an electrical configuration of the slot machine 2. The slot machine 2 includes a game control device 60 that performs basic control in the game of the slot machine 2. The game control device 60 includes a CPU 61, a ROM 62, and a RAM 63. When power is supplied to the slot machine 2, the CPU 61 reads the activation program stored in the ROM 62 and executes the program.

  The start switch sensor 65 is turned on when the start lever 21 is pressed, and an on signal (hereinafter referred to as a start signal) is output to the CPU 61. In response to the input start signal, the CPU 61 reads out a game control program (not shown) stored in the ROM 62 and data temporarily stored in the RAM 63, and starts the game process.

  Indexes 10a, 11a, and 12a are provided at the reference positions of the first reel 10, the second reel 11, and the third reel 12, respectively, and the photosensors 70, 71, and 72 are used for each rotation, respectively. The passage of the indexes 10a, 11a, 12a is photoelectrically detected. Detection signals from the photo sensors 70, 71, 72 are output to the CPU 61 as a reset signal for each reel. The first reel 10, the second reel 11, and the third reel 12 are press-fitted with drive shafts of stepping motors 75, 76, and 77, respectively. The reel 10, the second reel 11, and the third reel 12 rotate. In FIG. 3, for convenience, the first reel 10 and the stepping motor 75, the second reel 11 and the stepping motor 76, and the third reel 13 and the stepping motor 77 are surrounded by solid lines. Reference numerals 80, 81, and 82 denote drivers for driving the stepping motors 75, 76, and 77, respectively.

  The CPU 61 is provided with a pulse counter (not shown) for each stepping motor, and counts the number of drive pulses supplied to each stepping motor. As a result, every time a reset signal is input from the photosensors 70, 71, 72, it is cleared and counted up again. By monitoring the count value of the pulse counter for each reel, the CPU 61 can identify, for example, which symbol has moved on the center winning effective line, and how much the reel should be rotated. It is possible to predict whether the target symbol will move on the winning line.

  The first stop switch sensor 85 is provided inside the first stop button 22 and is turned on when the first stop button 22 is pressed, and an on signal (hereinafter referred to as a first stop signal) is directed to the CPU 61. Output. In response to this, the CPU 61 refers to a symbol table (not shown) stored in the ROM 62 and stops the target symbol on the winning winning line among the symbols arranged on the first reel 10. Thus, the supply of the drive pulse to the stepping motor 75 in the driver 80 is controlled.

  The second stop switch sensor 86 is provided inside the second stop button 23 and is turned on when the second stop button 23 is pressed, and outputs an on signal (hereinafter referred to as a second stop signal) to the CPU 61. In response to this, the CPU 61 refers to a symbol table (not shown) stored in the ROM 62 and stops the target symbol on the winning winning line among the symbols arranged on the second reel 11. As described above, the supply of drive pulses to the stepping motor 76 in the driver 81 is controlled.

  The third stop switch sensor 87 is provided inside the third stop button 24 and is turned on when the third stop button 24 is pressed, and outputs an on signal (hereinafter referred to as a third stop signal) to the CPU 61. In response to this, the CPU 61 refers to a symbol table (not shown) stored in the ROM 62 and stops the target symbol on the winning winning line among the symbols arranged on the third reel 12. Thus, the supply of drive pulses to the stepping motor 77 in the driver 82 is controlled.

  The CPU 61 includes a control unit 90, a random number acquisition unit 91, a winning combination determination unit 92, a stop determination unit 93, and the like. Based on the game control program stored in the ROM 62, the control unit 90 performs, for example, bet processing based on inserted medals and rotation / stop control of the first reel 10, the second reel 11, and the third reel 12. In addition, payout control or the like in the hopper device 35 is performed in the case of winning. In addition to this, the control unit 90 refers to the flags and data stored in the RAM 43 and selects any one of the first to sixth probability tables 95 to 100 stored in the ROM 42.

  When the power switch 40 is turned on and power supply to the slot machine 2 is started, the random number extraction unit 91 starts a random number update process and obtains a random number at the time when the ON signal from the start switch sensor 65 is output. To do. The winning combination determination unit 92 selects a winning table based on the setting value stored in the RAM 63 from the first to sixth winning tables 95 to 99 stored in the ROM 62, and extracts a random number using the selected winning table. It is determined whether the random number acquired in the section 91 is any of a plurality of types of winning combinations and losers set in advance.

  In the first to sixth winning tables 95 to 100, random numbers are assigned to each of a plurality of types of winning combinations and lost. Among these winning tables, the random number distribution to the winning combination is the lowest in the first winning table 95 and the sixth winning table 99, that is, the winning probability of the winning combination is the lowest in the first winning table 130, The 6-winning table 135 is the highest. When the setting value is “1” in the setting change, the first winning table 95 is selected, and when the setting value is “2”, the second winning table 96 is selected. Similarly, in the case of the set value “6”, the sixth winning table 100 is selected.

  In the stop determination unit (stop lottery means) 93, the slide switch 48 is set to “enable the stop function with a probability of 1/5”, “enable the stop function with 1/3”, and the BB mode. This is activated when the first game that has shifted to is started, and the random number acquired by the random number acquisition unit 91 and the first stop determination table (probability table) 102 stored in the ROM 62 or the second stop determination table (Probability table) From either one of the determination tables 103, it is determined whether or not to enable the stop function. In addition, since the setting in the slide switch 48 is memorize | stored in RAM63, the control part 90 determines whether the stop determination part is operated with reference to the memory | storage. When the stop determination unit 93 is operated, the control unit (table selection unit) 90 reads a stop determination table to be used from the ROM 62 based on the setting of the slide switch stored in the RAM 63.

  For example, when the slide switch 48 is set to “enable the stop function with a probability of 1/5”, the control unit 90 reads the first stop determination table 102 from the ROM 62 and reads “the stop function is 1 / If it is set to “Enable in 3”, the second stop determination table 103 is read from the ROM 62. When the setting of the slide switch 48 stored in the RAM 63 is set to enable or disable the stop function, the stop determination unit 93 is not activated. When the game in the BB mode ends and the stop function is enabled by the stop determination unit 93, the control unit (operation invalid control means) 90 performs a process of invalidating all input signals. At this time, when a reset switch 105, which will be described later, is turned on or a setting change / reset button 47 is turned on, a return signal is input to the control unit 90, so the control unit 90 executes a return process.

  In the first stop determination table 102, random numbers are distributed so that the stop function is effective with a probability of 1/5. On the other hand, in the second decision table 103, random numbers are distributed so that the decision function is effective with a probability of 1/3.

  The ROM 62 stores various tables in addition to the game control program and the symbol table, and is used by the control unit 90. The RAM 43 temporarily stores data on the number of throws in the game, in addition to storing a winning flag in the control during the game and processing data.

  The reset switch 105 is provided on the key cylinder 28. For example, when the release key 29 inserted into the key cylinder 28 is rotated in the direction B in FIG. 1, the reset switch 105 is turned on, and the on signal is output to the control unit 90. The control unit (release means) 90 receives the ON signal from the reset switch 105 and performs a return process. Thereby, when the stop function is turned on, the game in the slot machine 2 can be resumed by turning on the reset switch 105.

  Next, the operation of this embodiment will be described. FIG. 5 is a flowchart showing a flow when the setting is changed. After the administrator inserts the release key 29 into the key cylinder 28, the lower door 7 is opened by rotating the release key 29 in the direction A in FIG. Then, the setting key 50 is inserted into the key cylinder 46, the setting key 50 is rotated in the direction D in FIG. 3, and the key switch is turned on. When the power switch 40 is turned on in this state, the state of the slot machine 2 enters the setting change mode. In the setting change mode, the current setting value is displayed on the display unit 106 shown in FIG. For example, when changing the setting value, the setting change / reset button 47 is pressed. By pressing the setting change / reset button 47, the setting value displayed on the display unit 106 is changed. When the setting value intended by the administrator is displayed, the pressing operation of the setting change / reset button 47 is performed. And press the start lever 21. Thereby, the setting value displayed on the display device 106 is determined as the setting value in the game mode.

  When setting the stop function, slide the slide switch 48 to “disable the stop function”, “enable the stop function with a probability of 1/5”, “set the stop function to 1/3. Set to “Enable with” or “Enable the stop function”. To end the setting change mode, the setting key 50 inserted into the key cylinder 46 is rotated in the direction E in FIG. 3 to turn off the key switch, and the setting key 50 is pulled out from the key cylinder 46. When the setting key 50 is pulled out, the setting change mode is changed to the game mode. In this way, by setting the stop function, the setting intended by the game hall manager can be performed.

  FIG. 6 is a flowchart showing the flow of the game. First, a normal mode game is played. When the player inserts medals from the medal insertion slot 25, 1 to 3 medals are automatically bet, and the fourth and subsequent medals are credited. When the player depresses the start lever 21, game control is started by the control unit 90, and the first reel 10, the second reel 11, and the third reel 12 rotate. At the same time, the random number acquisition unit 91 acquires a random number at the time when the start signal output when the start lever 21 is pressed is output. The winning combination determining unit 92 determines whether the winning combination is a winning combination or not, based on the acquired random number and the winning table based on the set value stored in the RAM 63. A flag based on the determination is stored in the RAM 63.

  For example, when the flag stored in the RAM 63 serves as a BB transition combination for shifting to the BB mode, for example, when the symbol “7” is in the position where the symbol “7” is retracted in the symbol disposed on the first reel 10, the first When the stop button 22 is pressed, a first stop signal is input from the first stop switch sensor 85 to the control unit 90, so that the control unit 90 stops the symbol “7” on any of the winning lines. In addition, a drive stop signal is output to the driver 80. Thereby, the rotation of the first reel 10 is stopped so that the symbol “7” is positioned on the winning line. On the other hand, when the first stop signal is output when the symbol “7” is not in the retractable position, the rotation of the first reel 10 is stopped so that the other symbols are stopped on the winning line.

  When the pressing operation of the second stop button 23 and the third stop button 24 is performed, the same processing as the pressing operation of the first stop button 22 is performed. Then, when the symbol “7” is stopped on the same winning line, the BB transition combination is won and the gaming state shifts from the normal gaming state to the BB mode.

  After the transition to the BB mode and the first game is started, the random number is acquired by the random number acquisition unit 91 and the winning combination is determined by the winning combination determination unit 92 or the loss is determined as in the normal mode game. Is done. At the same time, the control unit 90 refers to the RAM 63 and confirms the setting in the slide switch 48. For example, when the setting of the slide switch 48 is “enable the stop function with a probability of 1/5” or “enable the stop function with a probability of 1/3”, the stop determination unit 93 is activated. . On the other hand, in the case of “validate the stop function” or “disable the stop function”, the stop determination unit 93 is not operated.

  For example, when the setting of the slide switch 48 is “enable the stop function with a probability of 1/5”, the stop determination unit 93 reads the first stop determination table 102 from the ROM 62 and stores it in the RAM 63. From the stored random number and the first stop determination table 102, it is determined whether or not to enable the stop function at the end of the BB mode.

  Similarly, when the setting of the slide switch 48 is “enable the stop function with a probability of 1/3”, the stop determination unit 93 reads the second stop determination table 103 from the ROM 62, and sets BB. At the end of the mode, decide whether to enable the stop function.

  When the game in the BB mode is executed and the end condition is satisfied, the BB mode is ended. For example, when the stop function is set to be valid, the control unit 90 enables the stop function when the BB mode ends. Thereby, for example, operations relating to the game such as pressing operation of the MAX bet button 15, operation of the start lever 21, operation of the first stop button 22, the second stop button 23, and the third stop button 24 become invalid. In this case, if a store clerk in the game hall inserts the release key 29 into the key cylinder 28 and rotates it in the direction B in FIG. 1, the reset switch 105 is turned on, the restoration process is performed by the control unit 90, and the game is resumed. It becomes possible to do. On the other hand, when the stop function is set to be invalid, the control unit 90 shifts from the BB mode to the normal mode.

  For example, in a game hall, there may be a notice that “if the game is to be stopped, the setting of the slot machine is a high setting (setting“ 6 ”)”. In this case, if the game is actually played in the slot machine and the stop function is enabled after the end of the BB mode, the player can play the game even if the slot machine setting is not actually set to high. Since the setting of the slot machine that performed the game can be recognized as a high setting, the game continues to be executed after the slot machine is reset.

  On the other hand, when the setting of the slot machine becomes high, the stop function may be invalidated. For this reason, even if the stop function is disabled at the end of the BB mode, the player cannot continue to execute the game because he cannot discard the possibility that the setting of the slot machine in which the game is being played is high. Will do. This can prevent the player from knowing whether or not the stop function is actually effective, and can also prevent the slot machine from being separated.

  In this embodiment, the probability of whether or not to enable the stop function is set by the slide switch. However, the present invention is not limited to this, and the stop function is set using a probability table that matches the set value. You may make it determine whether it validates. In this case, for example, with the slide switch, the game hall manager selects any one of “Enable stop function”, “Disable stop function”, and “Determine stop function by lottery”. A plurality of probability tables used when determining the stop function are stored in the ROM based on the setting values of the slot machine. For example, when “decide the stop function by lottery” is selected by the slide switch, the probability table based on the set value is selected from the plurality of probability tables stored in the ROM, and the stop function is enabled. Determine whether or not by lottery.
