Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a ball game machine having a plurality of components related to special symbols.

  Conventionally, a pachinko gaming machine that is one of the ball game machines is a pachinko gaming machine that performs a lottery or the like when a game ball wins a winning prize opening provided on the surface of the game board (first type) Pachinko machines). When a game ball wins a start winning opening, this pachinko gaming machine obtains a random number, performs a lottery, and stops after variably displaying the symbol on the symbol display device provided on the game board surface based on the random number lottery result indicate. Then, when a big win is won in the random number lottery, a special game consisting of performing a big win round as a unit special game that makes it easy to win a big winning opening provided on the game board surface is executed. In other words, the operation of opening the normally closed grand prize opening and closing it, for example, when a predetermined time elapses or a predetermined number of game balls enter the grand prize opening is repeated a predetermined number of times (round). . Furthermore, in recent years, pachinko gaming machines having two systems for shifting to special games have been proposed. In such a pachinko gaming machine, the start winning opening and symbol display device, which are components related to the first symbol, and the start winning port and symbol display device, which are components related to the second symbol, are independent of each other. Arranged.

Japanese Patent Laid-Open No. 8-280884

  Since the conventional pachinko gaming machine described above has two symbol display devices, the player may not be able to clearly recognize which symbol fluctuates or both fluctuate simultaneously. For this reason, even if two patterns of variable-figure games are provided, the entire pachinko game may become complicated and cause a decline in the gaming interests. There arises a problem that it is far from the content of “enjoying rolling of a game ball” which is the original game characteristic.

  The present invention has been made in view of the above problems, and an object thereof is to provide a ball game machine capable of efficiently displaying a plurality of special symbols.

In order to achieve the above object, in the ball game machine of the present invention, a random number is acquired each time a game ball wins the first and second start winning holes provided on the game board surface, and the game is based on the random number. It is determined whether or not to execute a special game that makes it easy to win by opening one variable winning opening provided on the board, and when executing the special game, the first special corresponding to the first start opening A second special symbol corresponding to the symbol or the second starting port, a symbol variation determining means for determining a decorative symbol corresponding to the special symbol, a special symbol display unit for displaying the special symbol and the decorative symbol, and A symbol display control unit that controls a symbol variation effect to stop display after the special symbol and the decorative symbol determined by the symbol variation determination unit are variably displayed on a decorative symbol display unit, and the symbol display control unit Yo A ball game machine comprising: a special game control means for performing the special game when the special symbol and the decorative symbol that are stopped and displayed are predetermined hit symbols. The symbol, the second special symbol, and the decorative symbol are displayed on the special symbol display unit and the decorative symbol display unit set in one symbol display device, and each of the first and second start winning prizes is won. wherein the first and upper number of which is set independently of the variation of the second special symbol is retained in the limit, the shell that number of pending on a common holding number display unit set in said one symbol display device for It is possible to identify which one of the special symbols is on hold by displaying different on-hold images formed with substantially the same shape for each on-hold, and the reserved image is displayed at a predetermined position on the screen. Follow digestion order as standard While identifiably displayed digestion order pending by displaying in rows define first determined respectively winning of the first and second respective starting winning opening, a second special symbol previously The first and the second winning prizes held for each of the starting winning awards are selectively displayed in accordance with the reserved digestion order and the first and second special symbols are variably displayed on the special symbol display unit. The variation of the second special symbol is digested, and for each of the special symbols, the decorative symbol is selectively displayed on one of the decorative symbol display units, and any special symbol among the special symbols is displayed. It is displayed whether the corresponding decorative design is changed, and the special game based on the winning at the first start winning opening and the special game based on the winning at the second starting winning opening are in any case the decorative design Execute special games on the display This is executed by opening a common variable prize opening after displaying a decorative symbol indicating, while the symbol variation determining means varies the probability of determining whether or not to execute the special game based on the random number. And the probability is varied under conditions common to the first and second start winning openings. As a result, even if there are multiple special symbols, they do not fluctuate simultaneously, and only one special symbol and one decorative symbol corresponding to it fluctuate, so the player recognizes only the fluctuating decorative symbol It is sufficient that the pachinko game as a whole can be prevented from becoming complicated, and the space on the game board can be made more efficient.

The symbol variation determining means is equipped with a function for varying the probability of determining whether or not to execute the special game based on the random number, and the probability varies under the conditions common to the first and second start winning openings. It is characterized by fluctuating.

  According to the present invention, each special symbol determined for winning of a plurality of start winning openings is alternatively selected in a predetermined order and is variably displayed on the special symbol display unit. Since the decorative symbols are alternatively displayed on one decorative symbol display unit, even if there are a plurality of special symbols, they do not change at the same time, and the player can change one decorative symbol. It is only necessary to recognize this, and it is possible to prevent the complication of the entire pachinko game and improve the game entertainment. In addition, since the space on the game board surface can be improved, it is possible to “enjoy the rolling of the game ball”, which is the game nature inherent to the ball game machine. Further, since each special symbol is displayed in a variable manner, the player can more reliably identify the changing special symbol. In addition, since the game ball winning status relating to each special symbol is sequentially displayed on the on-hold status display unit, the player can accurately grasp the progress of the game. In addition, since it is possible to identify which one of the special symbols the hold state is on hold, the player can specify the starting winning opening aiming for winning and play the game. In addition, since each special symbol, decorative symbol, and hold state are displayed on a special symbol display unit, a decorative symbol display unit, and a hold state display unit set in one symbol display device, the symbol display device is used in common as a game space. Can be suppressed, and it is possible to “enjoy the rolling of the game ball”, which is the original game nature of the ball game machine.

  FIG. 1 is a front view showing an appearance of a game board surface of a ball game machine according to an embodiment of the present invention. A symbol display device 11 having a liquid crystal display is disposed substantially at the center of the game board surface 10 of the ball game machine 1. The symbol display device 11 displays the two first special symbols 11a and the second special symbol 11b and one decorative symbol 11c, which are characteristic parts of the present invention, in a variable display, a stop display, etc. 11d is sequentially displayed.

  Below the symbol display device 11, two first start winning ports 12A and a second start winning port 12B in which game balls can be won are arranged at predetermined intervals in the horizontal direction. The first and second special symbols 11a and 11b start to change in response to the winning of a game ball at the first and second start winning holes 12A and 12B, respectively. One decorative symbol 11c starts to change in synchronization with a predetermined one of the two first and second special symbols 11a and 11b. The game ball hold state 11d is sequentially displayed corresponding to the winnings of the first and second starting winning ports 12A and 12B.

  The first and second special symbols 11a and 11b are displayed on both sides of the lower part of the symbol display device 11, the decorative symbol 11c is displayed at a substantially central portion of the symbol display device 11, and the reserved state 11d of the game ball is a symbol. It is displayed between the first and second special symbols 11a and 11b at the bottom of the display device 11. The symbol display device 11 is not limited to a liquid crystal display, and may be a display device such as a CRT or a dot matrix as long as an image can be displayed on the screen. The game ball hold state 11d is shared by the first and second start winning ports 12A and 12B, in which the hold of the first and second start winning ports 12A and 12B is displayed together. You may make it display separately in the appropriate location of the display apparatus 11, and you may make it provide the common hold display apparatus separate from the symbol display apparatus 11. FIG. Further, a special symbol display unit for displaying the first and second special symbols 11a and 11b and a decorative symbol display unit for displaying the decorative symbol 11c may be configured separately.

  First and second enlarging devices 13A and 13B for enlarging the opening width are disposed in the upper openings of the first and second start winning ports 12A and 12B, respectively. The first and second expansion devices 13A and 13B are normally connected to the first and second start winning openings 12A and 12B by maintaining a width that allows one game ball to pass but not two simultaneously. It is difficult to win game balls. Then, the first and second expansion devices 13A and 13B make it easy to win the game balls in the first and second start winning ports 12A and 12B by picking up the game balls in a wide range at the time of expansion. It has a function.

  An attacker unit 14 is disposed on the left side of the symbol display device 11. The attacker unit 14 is provided with a big prize opening 15 that is opened in the case of a jackpot game that is a special game. Here, the jackpot game is such that a special benefit is provided to the player when the first or second special symbol 11a, 11b (decoration symbol 11c) stopped and displayed on the symbol display device 11 is a jackpot symbol. A game. For example, a normally closed large winning opening 15 is opened a predetermined number of times, for example, 15 times (round) until a predetermined time of 30 seconds elapses or a predetermined number of game balls of 10 balls are won. ) A repetitive game.

  A winning opening 16 is disposed on the left side of the first starting winning opening 12A, and a game ball can pass through the upper left of the first starting winning opening 12A and the upper right of the second starting winning opening 12B. Two first operating gates 17A and second operating gates 17B are provided. The first and second operation gates 17A and 17B have a function related to the start of the normal symbol variation display in the normal symbol display unit 18 arranged on the right side of the second operation gate 17B when the game ball passes. Have. When this normal symbol stops at a predetermined symbol, the first and second expansion devices 13A, 13B of the first and second start winning prize openings 12A, 12B are activated for a predetermined time.

  At the lower end of the game board surface 10, an out port 19 through which game balls that have not won any of the first and second start winning ports 12A, 12B, the big winning port 15, and the winning port 16 are discharged is disposed. Yes. Further, the game board surface 10 is provided with a windmill 2 and a nail (not shown) for changing the falling direction of the game ball. And the front surface of the game board surface 10 is covered with the glass plate which is not shown in figure. Furthermore, below the game board surface 10, a ball handle (not shown) for guiding the game ball from the lower end of the game board surface 10 to the guide rail 3 and launching it to the upper end, first and second start winning holes 12A, 12B, An unillustrated award ball outlet for receiving a plurality of game balls when a game ball is won at the grand prize opening 15 and the award port 16 and a ball tray (not shown) for receiving those game balls are provided.

  An outline of the game of the ball game machine 1 configured as described above will be described with reference to FIG. When the player operates the bullet ball handle, the game ball is launched, guided by the guide rail 3 and released above the game board surface 10. While the game balls come into contact with the windmill 2 or the nail and the falling direction changes, a part of the game balls enter the winning opening 16 and the gaming balls that have not entered the winning opening 16 enter the out opening 19. When a game ball wins the winning opening 16, for example, five prize balls are paid out to the player from the prize ball payout exit.

  Further, when the game ball passes the first operation gate 17A or the second operation gate 17B, the normal symbol variation display on the normal symbol display unit 18 is started. Then, when the normal symbol display unit 18 stops displaying with a predetermined symbol, the first expansion device 13A or the second expansion device 13B of the first start winning port 12A or the second starting winning port 12B operates for a predetermined time. As a result, the first start winning port 12A or the second start winning port 12B is opened, and the winning to the first start winning port 12A or the second start winning port 12B becomes easy.

  When the normal symbol to be stopped is a symbol other than the above, the first expansion device 13A or the second expansion device 13B of the first start winning port 12A or the second starting winning port 12B does not operate. However, it is possible to win the first start winning opening 12A or the second start winning opening 12B. If the game ball passes through the first operation gate 17A or the second operation gate 17B while the normal symbol is changing in the normal symbol display unit 18, the corresponding change is suspended and sequentially executed.

  When the game ball wins the first start winning opening 12A or the second start winning opening 12B, for example, four winning balls are paid out to the player from the winning ball payout opening, and the first special symbol is displayed on the symbol display device 11. The decorative symbol 11c synchronized with the 11a or the second special symbol 11b and the first special symbol 11a or the second special symbol 11b starts to change. Here, in the case of the present embodiment, since the two first and second start winning ports 12A and 12B are provided, up to a total of eight game balls can be held. Therefore, the game ball hold state 11d displayed on the symbol display device 11 is composed of eight display parts representing eight hold game balls, and the hold display and the change order can be appropriately set. This is important from the viewpoint of playability.

  FIG. 2 is a diagram showing a hold display example and a change order example of the game ball hold state 11d. The hold display shown in FIG. 5A is an example in which the hold of the two first and second start winning ports 12A and 12B is displayed separately on the right and left to notify the player. That is, the four display portions on the left side of the drawing show the holding state 11da of the first start winning port 12A, and the four display parts on the right side of the drawing show the holding state 11db of the second start winning port 12B. In addition, white indicates a state of being held, and black painting indicates a state of not being held. The variation order shown in FIG. 5A is the case of (a) where only one type of holding is present, that is, only the first starting winning port 12A is reserved. The first special symbol 11a and the decorative symbol 11c synchronized therewith are sequentially changed.

  In the case of (b), there are two types of holdings, but there is a large number of holdings, that is, the two first and second starting winning ports 12A and 12B are both holding, but one of the first startings is held. Since the number of holds (3) of the winning opening 12A is larger than the number of holdings (2) of the other second starting winning opening 12B, the first special symbol 11a of the first starting winning opening 12A and the decorative design 11c synchronized therewith are displayed. First, the second special symbol 11b of the second start winning opening 12B and the decorative symbol 11c synchronized therewith are changed. As a result, the suspension saturation state is not prolonged, so that it is possible to prevent a reduction in the operation rate due to the so-called stoppage. Moreover, you may make it fluctuate not the number of holding | maintenance, but the holding | maintenance order, ie, the 1st special symbol 11a or the 2nd special symbol 11b of the 1st start winning opening 12A or the 2nd starting winning opening 12B previously reserved. As a result, the player can easily understand the trend of the on-hold state, so that an appropriate game method can be selected.

  In the case of (c), when there are two types of holds and the number of holds is the same, that is, the two first and second start winning ports 12A and 12B are both held, and one of the first start winning ports 12A is held. Is the same as the number of holdings (two) of the other second start winning port 12B, the holding order, that is, the first starting winning port 12A or the second starting winning port 12B previously held The first special symbol 11a or the second special symbol 11b is changed. As a result, the player can easily understand the trend of the on-hold state, so that an appropriate game method can be selected.

  The hold display shown in FIG. 5B is an example in which the hold of the two first and second start winning ports 12A and 12B is displayed together to notify the type. That is, although displayed from the left in order of hold, for example, the first start winning opening 12A is displayed in red (hatched line), and the second starting winning opening 12B is displayed in blue (outlined). Then, the changing order shown in FIG. 5B changes the holding order, that is, the first special symbol 11a or the second special symbol 11b of the first starting winning port 12A or the second starting winning port 12B previously held. . As a result, the player can immediately identify the on-hold state by visual observation, so that unnecessary confusion can be prevented.

  The hold display shown in FIG. 6C is an example in which the hold of the two first and second start winning ports 12A and 12B are displayed together but the type is not notified. That is, although displayed from the left in the order of hold, the same color (outlined) is displayed for both the first start winning opening 12A and the second starting winning opening 12B. Then, the changing order shown in FIG. 5C changes the holding order, that is, the first special symbol 11a or the second special symbol 11b of the first starting winning port 12A or the second starting winning port 12B previously held. . This makes it impossible for the player to distinguish between the hold states, so that a sense of expectation can be increased and interest can be enhanced.

  As described above, in the symbol display device 11, the first special symbol 11a or the second special symbol 11b and the decorative symbol 11c synchronized with the first special symbol 11a or the second special symbol 11b start to change and are determined at the time of winning a prize. For example, the fluctuation stops at the first special symbol 11a or the second special symbol 11b corresponding to one of the lost or jackpot and the decorative symbol 11c synchronized with the first special symbol 11a or the second special symbol 11b.

  When the first special symbol 11a or the second special symbol 11b stopped and displayed and the decorative symbol 11c synchronized with the first special symbol 11a or the second special symbol 11b are jackpot symbols, a special game is executed. First, the special winning opening 15 that is normally closed is opened. Then, when the game ball wins the big prize opening 15, for example, 15 prize balls are paid out to the player from the prize ball payout exit. The special winning opening 15 is temporarily closed, for example, when 30 seconds have elapsed since opening or when there is a winning of 10 balls. If there is a prize in the V zone provided inside the big prize opening 15 while the big prize opening 15 is open, the big prize opening 15 is once closed and then opened again. It is like that.

  If the opening and closing of the big prize opening 15 is a unit special game, the big hit as a special game consists of repeating the unit special game a plurality of times. For example, if a unit special game is repeated a maximum of 15 times (round), the special game will end. However, even if there is no V zone winning while the grand prize opening 15 is open, finish. When the special game is over, a lottery is performed as to whether or not to execute the probability variation game. When the lottery is won, a game in the probability variation state is executed.

  In such a configuration, a control method (operation) from when the game ball is won in the first start prize opening 12A or the second start prize opening 12B in the above-described ball game machine 1 until the probability variation game is executed and ended. This will be described with reference to the flowcharts of FIGS. First, as shown in FIG. 4, a series of control processes include a random number acquisition condition determination process (step S1), a symbol variation determination process (step S2), a special game control process (step S3), and a probability variation game control process (step S4).

  The random number acquisition condition determination process (step S1) is a control process in which a random number is acquired based on a winning game ball and game ball hold information is generated. The symbol variation determination process (step S2) is a control process in which it is determined whether or not a special game is to be executed, and the corresponding special symbol and decorative symbol variation are executed. The special game control process (step S3) is a control process for executing the special game when the execution of the special game is determined in step S2. The probability variation game control process (step S4) is a control process for executing a probability variation game that is started when a lottery is made after the special game ends and the lottery is won.

  FIG. 5 shows a flow of random number acquisition condition determination processing in step S1. That is, when a winning of a game ball is detected (step S10), “4” is added to the winning ball counter (step S11), and it is determined whether or not the winning is the first start winning opening 12A (step S11). S12). When the winning is in the first starting winning opening 12A, the number of the game balls held in the first starting winning opening 12A is read (step S13A), while on the other hand, in the second starting winning opening 12B. The number of game balls held at the second start winning opening 12B is read (step S13B).

  Then, it is determined whether or not the retained ball of the first or second start winning opening 12A, 12B is within the upper limit (step S14), and the retained ball of the first or second start winning opening 12A, 12B is within the upper limit. When there is, the winning random number and the effect determining random number of the first or second start winning opening 12A, 12B are acquired (steps S15, S16). Then, “1” is added to the number of reserved balls corresponding to the first or second start winning opening 12A, 12B (step S17), and the winning random number acquired in the reserved area and the first or second start winning opening 12A, Information regarding which of 12B has been won is stored (step S18), and the hold information is displayed and controlled on the hold display unit based on the hold information (step S19).

  FIG. 6 shows a flow of the symbol variation determination process in step S2. That is, the presence / absence of the number of reserved balls at the first and second start winning ports 12A, 12B is determined (step S20), and when there are the number of reserved balls at the first and second start winning ports 12A, 12B, the pattern variation is changed. A determination is made as to whether or not to allow symbol variation to be performed (step S21). When the symbol does not change at present, the symbol change is permitted, and the winning determination table corresponding to the gaming state is read (step S22). Subsequently, a pending digest determination process described later is performed (step S23), and it is determined whether or not the winning random number is a win (step S24).

  When the winning random number is winning, the winning flag is turned on (step S25), the winning variation pattern corresponding to the effect determining random number is determined (step S26A), and the winning symbol is set to the special symbol and the decorative symbol (step S27A). ). On the other hand, when the winning random number is out of the range, the out-of-range variation pattern corresponding to the effect determination random number is determined (step S26B), and the out-of-range symbol is set as the special symbol and the decorative symbol (step S27B). Then, the determined variation symbol command or the variation symbol command and the variation special symbol information which is information indicating which of the first special symbol or the second special symbol is to be varied are transmitted (step S28). Subsequently, the symbol variation prohibition flag is turned on to enter a symbol variation prohibition state (step S29), and the symbol variation timer is set to zero (0) (step S30).

  FIG. 7 shows a flow of the pending digest determination process in step S23. This example shows the pending digestion determination process in the case shown in FIG. That is, it is determined whether or not both the first and second start winning ports 12A and 12B are on hold (step S231), and when both the first and second start winning ports 12A and 12B are not on hold, there is a hold. It is decided to digest the reserved balls of the first or second start winning opening 12A, 12B (step S232). On the other hand, when both the first and second start winning ports 12A and 12B are on hold, it is determined whether or not the number of held balls in the first start winning port 12A is equal to or larger than the number of held balls in the second start winning port 12B. (Step S233).

  Then, when the number of retained balls in the first start winning opening 12A is equal to or larger than the number of retained balls in the second starting winning opening 12B, it is decided to digest the retained balls in the first starting winning opening 12A (step S234). When the number of retained balls in the first start winning port 12A is smaller than the number of retained balls in the second start winning port 12B, it is determined to digest the retained balls in the second start winning port 12B (step S235).

  FIG. 8 shows a flow of the special game control process in step S3. First, a unit special game is started (step S31). That is, the special winning opening driving source 14d of the attacker unit 14 is driven and controlled, and the opening of the special winning opening 15 is started. Then, depending on whether a prescribed number of balls (for example, 10 balls) has won since the grand prize opening 15 is opened or a prescribed time (for example, 30 seconds) has passed (step S32), the big prize opening 15 is once opened. Etc. are terminated (step S33).

  The above unit special game is, for example, continuous for a maximum of 15 rounds. If there is no winning in the V zone while the special winning opening 15 is opened, the special game is ended in that round. Next, it is determined whether or not the round is the final round (step S34). When this round is the final round, the special game is ended. On the other hand, when the round is not the final round in step S34, the process returns to step S31 and the subsequent round is started.

  FIG. 9 shows a flow of the probability variation game control process in step S3. First, it is determined whether or not the special game has ended (step S41). Next, whether or not to execute the probability variation game is drawn (step S42). If this lottery is won, the probability variation state is set (step S43). Here, the probability change state includes, for example, changing the normal symbol lottery probability to a high probability, extending the start winning time expansion time, shortening the symbol variation time, and the like. After the game in the probability variation state is executed (step S44), processing for returning the probability variation state to the normal state is performed (step S45). In this way, it is possible to prevent the game from becoming monotonous by changing the probability that the special game is executed, and to provide more interest to the player.

  As described above, according to the ball game machine 1 of the present embodiment, the first and second special symbols 11a and 11b determined with respect to the winnings of the first and second starting winning ports 12A and 12B are determined in advance. Each of the orders is alternatively selected and displayed on the special symbol display unit in a variable manner, and one decorative symbol 11c corresponding to the alternatively selected first special symbol 11a or second special symbol 11b is displayed as a decorative symbol. The display is variably displayed. Therefore, even if there are two first and second special symbols 11a and 11b, they do not fluctuate simultaneously, and the player only needs to recognize one fluctuating decorative symbol 11c. It is possible to improve the game interest by preventing complication of the entire game, and to improve the efficiency of the space of the game board surface 10. It ’s possible to enjoy “rolling”.

  Further, since the first and second special symbols 11a and 11b are individually displayed in a variable manner, the player can more reliably identify the changing first special symbol 11a or the second special symbol 11b. Further, the game ball winning hold state 11d according to the first and second special symbols 11a and 11b is sequentially displayed on the hold state display unit, so that the player can accurately grasp the progress of the game. Further, since the hold state 11d is displayed so as to be able to identify which one of the first and second special symbols 11a and 11b is on hold, the player can select the first start winning opening 12A or the second It is possible to play by specifying the 2 start winning opening 12B. Further, the first and second special symbols 11a and 11b, the decorative symbol 11c, and the hold state 11d are displayed on the special symbol display unit, the decorative symbol display unit, and the hold state display unit that are set in one symbol display device 11. The symbol display device 11 can be used in common to prevent the game space from being compressed, and the game nature inherent to the ball game machine 1 can be “enjoying the rolling of the game ball”.

  In the above-described embodiment, the ball game machine includes the two first start winning openings 12A and the second start winning opening 12B, and can display the two first special symbols 11a and the second special symbols 11b. However, the present invention is not limited to this, and can be applied to a ball game machine having three or more start winning holes and capable of displaying three or more special symbols 11b. is there. Moreover, although the holding state 11d of the game ball has been described with the display indicating the holding ball, the present invention is not limited to this. For example, the same operation and effect can be achieved even with any display of numbers, characters, images, and the like. In addition, the decorative symbols 11c corresponding to the first and second special symbols 11a and 11b may be set so as to perform separate symbols (characters) and variation modes. With this configuration, the variation of the decorative symbols 11c It is possible to easily identify which of the special symbols 11a and 11b the decorative symbol 11c is changed from the aspect or the like.

  The present invention can be applied not only to a so-called pachinko machine but also to other ball game machines such as an arrangement ball as long as it is a ball game machine using game balls.
