Description

  The present invention relates to a gaming machine that displays a winning lottery result for determining a winning or losing after a symbol change display.

  There is known a pachinko machine in which a winning lottery is performed when a game ball launched toward a game board wins a specific winning opening (starting winning opening) or determines a win. If this pachinko machine is won by winning, it will be shifted from the normal mode to the winning mode and a large number of prize balls can be obtained. The result of the winning lottery is displayed on an image display device such as a 7-segment display device or a liquid crystal display as disclosed in Patent Document 1, for example. In a pachinko machine using a liquid crystal display, symbols are displayed in a variable manner on the image display surface. When a certain time has elapsed after the symbols are displayed, the symbols are stopped and displayed on the screen. At this time, for example, when three identical symbols are aligned in a row, it represents a win, and when arranged in other ways, it represents a loss. By the way, when winning a win, simply shifting to the winning mode makes the game uniform and easy to get bored with the game. A pachinko machine that shifts to a probability variation mode that is higher than the normal mode is also provided. In such a pachinko machine, whether or not to shift to the probability variation mode is determined at the time of winning, and when it is determined to shift to the probability variation mode, the mode is shifted to the probability variation mode following the hit mode. Whether or not to shift to the probability variation mode is displayed depending on, for example, the type of symbol displayed at the time of winning the winning combination, or is displayed by an effect image in the winning mode.

Encouraging players to have an expectation of winning while the symbols are displayed is an important factor in enhancing the player's interest in the game. Various pachinko machines are provided by various manufacturers. As one of such pachinko machines, for example, a moving character doll or model, etc., is provided as a director, and the director is operated during the display of the change in the design to increase the expectation of winning. It has been known. The stage effect is set so that it is easy to be activated in the case of a win and difficult to operate in case of a loss. be able to.
JP 2001-346965 A

  However, if the winning combination is selected for the lottery in the normal mode, it will move in a unique way and raise the expectation of winning, but it will not work at all in the winning mode and will function as a game board decoration or It only appeals to the player that it is in the hit mode by a certain movement, and the function is demonstrated even if the manufacturing cost of the pachinko machine has increased in providing a director and a mechanism to operate it However, it was difficult to say that the player was able to appeal to the player as much as the cost.

  The present invention has been made in consideration of the above-mentioned problems, and it is possible to make an appeal to the player that is commensurate with the cost incurred when providing a performance accessory by enhancing the utility value of the performance feature. An object is to provide a game machine that can be used.

  In order to achieve the above object, the present invention comprises an image display device for displaying a result of winning lottery for determining winning or losing on an image display surface, and a normal mode, a winning mode more advantageous than the normal mode, and the normal mode. A game is performed in the probability variation mode in which the probability of winning in the win is higher than in the mode, and when winning in the normal mode, the game shifts only to the win mode or continues to the probability change mode following the win mode In the normal mode, the parameter indicating the degree of winning expectation determined based on the result of the winning lottery and the parameter indicating the probability that the reach display is displayed in the process of the variation display of the symbol are produced in the normal mode A parameter display device individually displayed on a plurality of display units using a design, and the parameter display device, the image display A moving means for moving between an appearance position located in front of the image display surface and a retreat position retracted from the front of the image display surface, and whether or not to move the parameter display device from the retracted position to the appearance position. A movement lottery means determined by a movement lottery executed in a mode; a movement control means for moving the parameter display device to the appearance position when winning the movement lottery or when winning in the winning lottery; Stop operation means for sequentially stopping the effect symbols that are variably displayed in the hit mode for each display unit, and display control means for performing change display of the effect symbols on each of the display units during the hit mode, The display control means stops the effect symbol in response to the operation of the stop operation means, and the probability variation mode. And wherein varying the type of the performance symbols to be stopped depending on whether or not to shift to the mode.

  In addition, it is preferable that the probability of shifting to the probability variation mode is increased in accordance with the number of operations of the stop operation unit from when the variation display of the effect symbol is started to when it is stopped.

  In addition, when it is determined to shift to the probability variation mode, a probability variation display lottery unit is provided that determines which of the plurality of display units displays the transition to the probability variation mode by probability variation display lottery. It is preferable that the display control means stops the effect design that displays the transition to the probability variation mode on the display unit determined in the probability variation display lottery.

  According to the present invention, the effect symbols that are variably displayed in the hit mode are sequentially stopped for each display unit by the player's stop operation, and the effect symbols to be stopped are different depending on whether or not the mode is shifted to the probability variation mode. Therefore, it is possible to use the parameter display device, which is a production accessory, even in the hit mode, and increase the utility value of the parameter display device and play an appeal that is commensurate with the cost incurred when providing the production feature. Can be done to the person. In addition, by using the parameter display device, it is possible to give the player a unique interest that has not existed before.

  In addition, since the probability of transition to the probability variation mode is determined according to the number of stop operations of the effect symbol from the start of the change display of the effect symbol to the stop, the game for performing the stop operation of the effect symbol It is possible to increase the player's motivation and increase the utility value of the parameter display device, which is a performance object, and make an appeal to the player commensurate with the cost incurred when providing the performance object. it can. Further, it is possible to give a sense of tension to the game in the hit mode that tends to be redundant.

  In addition, when it is determined to shift to the probability variation mode, it is determined by probability variation display lottery which of the plurality of display units displays the transition to the probability variation mode, so that the content of the game can be predicted. It is possible to increase the player's tension when stopping the production design.

  In FIG. 1, the pachinko machine 10 includes a game board 10a. A game area 11 is formed on the front surface of the game board 10a, and the launched game ball flows down the game area 11. The game area 11 is provided with a start winning opening 12 and a normal winning opening 13. When a game ball wins each winning opening, a predetermined number of game balls are paid out as a prize ball. The game balls that have been paid out can be used for games. Although not shown in detail, the game area 11 is provided with game nails that change the movement of the flowing game balls.

  When a game ball wins the start winning opening 12, a winning lottery for determining a winning or losing is performed. If the winning is won, the mode is changed to the winning mode and the attacker 14 is released. When the attacker 14 is opened, most of the game balls are guided to the big winning opening on the inner surface, and a large number of prize balls can be obtained. The attacker 14 is closed when a predetermined number (for example, 10) of game balls have won a prize winning opening or when the opening time is 30 seconds, for example, thereby completing the first round. In the hit mode, the opening and closing of the attacker 14 is repeated and the process ends in the fifteenth round. The pachinko machine 10 can be played in the probability variation mode in addition to the normal mode and the winning mode. When transitioning to the probability variation mode, the probability of winning a win is higher than in the normal mode. Whether or not to shift to the probability variation mode is assigned when winning, and when the transition to the probability variation mode is determined, the mode is shifted to the probability variation mode following the hit mode.

  A center accessory 15 is provided at the center of the game area 11. The center accessory 15 is provided with a liquid crystal display device (image display device) 16 on which a screen (image display surface) 16a for displaying the result of the winning lottery is exposed. A center route 15 is formed with a guide route for taking a game ball from a take-in port provided around the center accessory 15 and guiding the taken game ball to another position. To a position where it is easy to win.

  In FIG. 2, the center accessory 15 is provided with a rectangular plate-shaped parameter display device 21. The parameter display device 21 appears in front of the screen 16a of the liquid crystal display 16 and a part of the screen 16a that is hidden behind the center accessory 15 and cannot be visually recognized (a position indicated by a broken line in the figure). It moves to and from the appearance position (the position indicated by the two-dot difference line in the figure). The movement time between the retracted position and the appearance position of the parameter display device 21 is 2 seconds.

  In the normal mode, whether or not to move the parameter display device 21 from the retracted position to the appearance position is determined by moving lottery described later. The parameter display device 21 also moves to the appearance position at the start of the 15th round of the hit mode, that is, at the start of the final round of the hit mode.

  The parameter display device 21 is provided with three parameter display portions 22a, 22b, and 22c that are 7-segment display devices. From each display part 22a-22c, the production design 24 (refer FIG. 6) showing a 2-digit number is displayed. When the parameter display device 21 moves to the appearance position in the normal mode, the parameter display unit 22a displays a parameter indicating the probability that the reach display is displayed in the process of the symbol variation display, and the parameter display unit 22b indicates the hit expectation degree. The parameter is displayed, and the parameter display unit 22c displays a parameter indicating the expected degree of transition to the probability variation mode.

  Further, when the parameter display device 21 moves to the appearance position in the fifteenth round of the hit mode, the effect symbols 24 are variably displayed on the parameter display portions 22a to 22c, and the effect symbols 24 that are variably displayed are displayed by the player. The parameter display units 22a to 22c are sequentially stopped by the stop operation. When the effect symbol is stopped, either “-” indicating that the mode is not shifted to the probability variation mode or “77” indicating that the mode is shifted to the probability variation mode is displayed from the parameter display units 22a to 22c. As a result of the player performing a stop operation, “77” is displayed on any of the parameter display units 22a to 22c, or “−−” is displayed on all of the parameter display units 22a to 22c. When “77” is displayed on all the parameter display units 22a to 22c later, the mode shifts to the probability variation mode after the hit mode ends.

  On the screen 16 a of the liquid crystal display 16, for example, three rows of symbols 23 each having a row of numbers 0 to 9 are displayed. When a game ball wins at the start winning opening 12, the change display of the symbol 23 is started, and the symbol 23 scrolls from top to bottom. The symbols 23 stop one by one in sequence (in order from left to right to middle), and when all symbols are stopped, the same symbol 23 is hit, and otherwise it is lost. In order for the same symbol 23 to be aligned, two identical symbols 23 are aligned on the left and right, and if the remaining one symbol is aligned, a reach display that is a winning display is performed. In addition to the symbol 23, various effect images are also displayed from the liquid crystal display 16.

  In FIG. 3, the pachinko machine 10 includes a control unit (display control means and movement control means) 30a. The control unit 30a controls the operation of the entire pachinko machine 10 such as opening / closing control of the attacker 14, display control on the liquid crystal display 16, display control on the parameter display device 21 in accordance with a game control program stored in the memory 30b.

  The start winning sensor 31 detects a game ball that has entered the start winning opening 12. The normal winning sensor 32 detects a game ball that has entered the normal winning slot 13. The special prize sensor 33 detects a game ball that has entered the big prize opening that appears when the attacker 14 opens. The prize ball payout device 35 pays out a prescribed number of game balls as prize balls in response to a payout command input when the game balls win each winning opening.

  The game ball launching device 36 launches game balls one by one into the game area 11 in response to the turning operation of the launch handle of the player. The launch strength of the game ball is adjusted according to the amount of rotation of the launch handle. The attacker drive device 37 opens and closes the attacker 14 in the hit mode.

  The winning lottery unit 40 receives a command from the control unit 30a when a game ball wins the start winning opening 12, performs a winning lottery using random numbers, and determines a winning or a lose. In the hit, a small hit that is shifted only to the hit mode and a big hit that is shifted to the probability variation mode after the hit mode are set. In the winning determination table used in the winning lottery, all of the random numbers extracted in the lottery are assigned with one of lose, small hit, and big win. The number of random numbers is determined so that each of the small hits and the big wins is selected by 1/2. Then, the loss, the small hit or the big win is determined depending on which value the random number extracted at the time of the lottery corresponds to. Note that in the winning lottery, only the loss or the winning may be determined.

  The symbol lottery unit 41 performs symbol lottery according to the winning lottery result, and determines a stop pattern of the symbol 23 to be stopped after the variable symbol 23 is displayed. In the case of winning, the reach display is always displayed in the process of the variable display of the symbol 23, but the manner in which the loss is displayed in the stop pattern of the loss via the reach display, that is, the same symbol 23 is displayed. A stop pattern is also included in which a loss is displayed after two stops.

  The movement lottery unit (movement lottery means) 42 performs a movement lottery using random numbers and determines whether or not to move the parameter display device 21 from the retracted position to the appearance position. The moving lottery unit 42 includes a winning table and a lose table, and the extracted random number is checked against a table corresponding to the winning lottery result. In the winning table, the number of winning random numbers is set so that the probability that the parameter display device 21 moves to the appearance position is higher than that in the lose table. For this reason, when the parameter display device 21 moves to the appearance position in the normal mode, a player's sense of expectation increases. When the parameter display device 21 is moved, the control unit 30a drives a motor (moving means) 21a. The motor 21a is formed of a stepping motor, and the control unit 30a inputs the preset number of pulses to the stepping motor to move the parameter display device 21 between the retracted position and the appearance position.

  The first display lottery unit 43a is activated when the moving lottery is won, and determines a numerical value to be displayed on the parameter display unit 22a by parameter lottery. The first display lottery unit 43a includes a winning table and a lose table. In each table, any one of numerical values “0%” to “99%” displayed on the parameter display unit 22a is an individual random value. Assigned to. In the winning table, the number of random values to which each numerical value is assigned is set so that a relatively higher numerical value than that of the lose table is selected. For this reason, the higher the numerical value indicating the parameter in the parameter display unit 22a, the higher the expectation that the player's reach display is displayed, that is, the expectation for winning.

  Similarly, the second display lottery unit 43b determines a numerical value to be displayed on the parameter display unit 22b by parameter lottery. Similarly to the first display lottery unit 43a, the second display lottery unit 43b determines the numerical value to be displayed on the parameter display unit 22b according to the winning or losing from either “0%” to “99%”, and wins the winning The selection probability of the numerical value is set so that the numerical value displayed in the case is higher. For this reason, the higher the numerical value indicating the parameter in the parameter display portion 22b, the higher the player's expectation for winning.

  Similarly, the third display lottery unit 43c determines a numerical value to be displayed on the parameter display unit 22c by parameter lottery, but the first and second display lottery units 43a and 43b have a different table configuration, and the third display lottery unit The unit 43c includes a probability variation table used when winning a jackpot and a non-probability variation table used when winning a loss or a bonus. In each table, a numerical value “0%” to “99%” displayed on the parameter display unit 22c is assigned to each random number value. In the probability variation table, the number of random values assigned with each numerical value is set so that a numerical value relatively higher than that in the non-probable variation table is selected. For this reason, the higher the numerical value indicating the parameter in the parameter display unit 22c, the higher the player's expectation for the probability variation mode.

  The image memory 45 stores image data of the symbols 23 and various effect images. The image data of the symbol 23 is given a head address for each type, and the control unit 30a identifies the type of the symbol 23 by identifying the head address.

  The control unit 30a changes the parameter display unit 21a → parameter display unit each time a stop button (stop operation means) 46 provided on the pachinko machine 10 is pressed during the variation of the production pattern 24 in the fifteenth round of the hit mode. The effect symbol 24 is stopped in the order of 21b → parameter display portion 21c.

  The probability variation display lottery section (probability variation display lottery means) 47 is activated when a big win is won in the winning lottery. The probability variation display lottery unit 47 executes the probability variation display lottery, and when the effect symbol 24 is stopped in the fifteenth round in the winning mode, the parameter display units 22a to 22c indicate that the mode changes to the probability variation mode. That is, it is determined whether to display that the jackpot is won. The display mode determined by the probability variation display lottery unit 47 includes a mode for displaying that the parameter winning units 22a to 22c have won the jackpot.

  The timer 48 is used when time management of various devices such as the opening time of the attacker 14 and the operation time of the parameter display device 21 is performed. The control unit 30a controls each device by using the timer 48.

  Next, the operation of the pachinko machine 10 will be described with reference to FIGS. As shown in FIGS. 4 and 5, when the player performs the turning operation of the launch handle, the game balls are launched into the game area 11 one by one. The game ball flows down the game area 11 while colliding with an obstacle such as a game nail. The game balls that have flowed down the game area 11 win the start winning opening 12 or the normal winning opening 13, or are collected as out balls if they do not win. When a game ball wins the start winning port 12 or the normal winning port 13, the winning ball is paid out.

  When a game ball wins at the start winning opening 12, a winning lottery is executed, and a winning or losing is determined. When the winning lottery ends, the symbol lottery is performed according to the result, and the stop pattern of the symbol 23 is determined. When the winning lottery is completed, a moving lottery is performed according to the result, and it is determined whether or not to move the parameter display device 21 from the retracted position to the appearance position. Furthermore, when winning a win and winning a big win, the probability variation display lottery unit 47 performs a probability variation display lottery.

  When it is decided to win the moving lottery and move the parameter display device 21 to the appearance position, the parameter display lottery is performed by the first to third display lottery units 43a to 43c and displayed by the parameter display units 22a to 22c. The numerical value of the parameter to be determined is determined.

  As shown in FIG. 6A, when the parameter display lottery is finished, the variable display of the symbol 23 is started. When the variable display of the symbol 23 is started, the parameter display device 21 starts to move from the retracted position to the appearance position. The control unit 30a moves the parameter display device 21 to the appearance position in a state where the numerical values of the parameter display units 22a to 22c are variably displayed.

  As shown in FIG. 6B, when the parameter display device 21 moves to the appearance position, the numerical values determined by the parameter display lottery are displayed from the parameter display units 22a to 22c.

  When winning in the winning lottery and shifting to the winning mode, the control unit 30a moves the parameter display device 21 to the appearance position simultaneously with the start of the fifteenth round. At this time, the parameter display device 21 moves to the appearance position in the state in which the effect symbol 24 is variably displayed on the parameter display units 22a to 22c. 2 seconds after the parameter display device 21 starts moving, that is, 2 seconds after the start of the fifteenth round, the parameter display device 21 arrives at the appearance position, so two seconds after the start of the movement from the start of the fifteenth round. The operation of the stop button 46 is validated.

  Then, as shown in FIG. 7, when the player presses the stop button 46, the effect symbol 24 of the parameter display unit 22a stops (the state of FIG. 7A), and then the effect symbol 24 of the parameter display unit 22b changes. It stops (state of FIG.7 (b)), and finally the effect symbol 24 of the parameter display part 22c stops (state of FIG.7 (c)). When the jackpot is won, “77” is displayed on the parameter display portions 22a to 22c determined by the probability variation display lottery.

  Further, as shown in FIG. 7D, when the mode for displaying that the jackpot is won in all the parameter display units 22a to 22c is determined by the probability variation display lottery, all the display units 22a to 22 are temporarily set. After “-” is displayed in 22c, “77” is displayed in all the display units 22a to 22c.

  In addition, when “77” is displayed on any or all of the parameter display units 22a to 22c, simultaneously “probable change” is displayed on the liquid crystal display 16 and the mode is changed to the probability variation mode after the hit mode. Is displayed to the player on the liquid crystal display 16. When the 15th round is completed, the parameter display device 21 moves to the retracted position.

  If the effect symbols 24 of all the parameter display units 22a to 22c have not stopped even after 10 seconds have passed since the start of the 15th round, it is considered that the player has no intention to press the stop button 46. Then, all the changing production symbols 24 are automatically stopped. In addition, when 10 game balls are won in the big prize opening and the fifteenth round is finished during the variation display of the production symbol 24 on the parameter display units 22a to 22c, the variation display of the production symbol 24 is performed. The parameter display device 21 moves to the retracted position. In this case, when the jackpot is won, the characters “probability change” are displayed on the liquid crystal display 16, so that the player can know that the mode is changed to the probability variation mode after the hit mode.

  When the winning mode is completed, if the winning type is a big hit, the mode is shifted to the probability variation mode following the winning mode, and if the winning type is the small win, the normal mode is transferred again.

  In the above embodiment, it is displayed whether or not the big win is won in the final round of the hit mode. For example, the parameter display device 21 is moved to the appearance position together with the start of the hit mode (or the start of the first round), and for each round. The parameter display device during the winning mode, such as displaying the variation of the effect symbol and displaying that the winner is won in any of the rounds, or determining the round in which the parameter display device 21 is moved to the appearance position by lottery. The timing for displaying that the jackpot is won may be set as appropriate.

  In the above embodiment, whether or not to shift to the probability variation mode is determined by winning lottery, but whether or not to transition to the probability variation mode is determined after pressing the stop button 46, and depending on the number of times the stop button 46 is pressed The probability may be changed. Hereinafter, an example of this case will be described with reference to FIG. 8. However, since the processing flow until the stop button 46 is activated is the same as that in the above embodiment, the illustration and description are omitted, and the stop button 46 is operated in the hit mode. Only the flow after being validated will be described.

  In this embodiment, for example, a probability reference table is provided in which the number of times the stop button 46 is pressed and the transition probability to the probability variation mode are associated with each other. In this probability reference table, for example, “the number of times of pressing is 0-5 times → the transition probability is 0%, the number of times of pressing is 5-10 times → the transition probability is 50%, the number of times of pressing is 11 times or more → the transition probability is 90%”. The number of times of pressing and the transition probability are associated so that the transition probability becomes high. In addition to this, a lottery table used in the probability variation lottery for determining whether or not to shift to the probability variation mode is provided for each transition probability of the probability variation reference table.

  Then, as shown in FIG. 8, when the mode is changed to the hit mode, the control unit 30a counts the number of times the stop button 46 is pressed within a predetermined time after the operation is validated. After a predetermined time has elapsed, the probability reference table is referred to, and the transition probability to the probability variation mode is identified from the counted number of presses. Then, the control unit 30a executes the probability variation lottery using the lottery table corresponding to the identified transition probability, and determines whether to shift to the probability variation mode after the winning mode. After the probability variation lottery, the effect symbol 24 is stopped and the result of the probability variation lottery is displayed on the parameter display unit 22a. Similar processing is performed by the parameter display units 22b and 22c. When it is decided to win the probability variation lottery and shift to the probability variation mode, the parameter display portions 22a to 22c determined by the probability variation display lottery are displayed as in the above embodiment. The predetermined time may be set as appropriate as long as the same processing can be repeated three times for each of the parameter display units 22a to 22c within a range not exceeding 10 seconds from the start of the round.

  In the above embodiment, the parameter display device 21 has three parameter display units. For example, in addition to the above three parameters, a parameter indicating a display probability of super reach display having a higher expectation to hit than reach display is selected. You may provide the display part which displays an appropriate parameter, such as providing the display part to display.
