  In such pachinko machines, special games are inevitably started when a special symbol is won. For this reason, the probability that the special symbol is won is set to a low probability of about 1/200 to 1/350. Because of this low probability setting, the normal game until the transition to the special game is generally easy to prolong and monotonous. In order to enhance the interest of pachinko machines, it is important to devise so that ordinary games that occupy most of the entire game do not become monotonous.

  In many conventional pachinko machines, development efforts are focused on sustaining the player's interest in the game during the normal game period by stimulating the player's sense of expectation with a design called a decorative pattern. There is a feeling that has been done. However, it is still luck in the end to determine the special symbol that will be the special game start condition. Therefore, the ideal form of games that compete for skills is being lost. This has become a major cause for players who are confident in their skills to leave the game.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a ball game machine that enhances the interest of the game with respect to the transition control to the special game.

  In order to solve the above-described problems, a ball ball game machine (10) according to an aspect of the present invention is provided at different positions in a game board (100) in which a game area (102) is formed and a game area (102). The first (for example, the specific opening 184) and the second specific winning opening (for example, the effective time extension opening 186 and the effective time shortening opening 188) and the start winning opening (provided at a predetermined position in the game area (102)) 112) and valid / invalid determination means (for example, start winning determination means for executing lottery with a predetermined probability in order to determine whether or not the validity period can be set in response to the drop of the game ball into the start winning opening (112) 214), when the result of the lottery is a win, an effective period control means (230) that initially sets a predetermined period as an effective period, and a first specific winning opening (for example, specific Triggered by 落入 the game balls to 184), comprising special game shifting unit to shift the game to an advantageous special game state to the player (e.g. special game controller 208), the. The validity period control means (230) changes the length of the validity period triggered by the drop of the game ball into the second specific prize opening (for example, the validity time extension opening 186 or the validity time shortening opening 188).

  According to this aspect, when the game ball falls into the specific winning opening within the effective period, the game shifts to the special game. When a lottery executed when the game ball enters the start winning opening is a win, a valid period of a predetermined length is set. In order to shift to the special game, the player must drop the game ball into the first specific winning opening within the effective period. However, even if the effective period is once set, the length is appropriately changed according to the game situation, so that even during the effective period advantageous to the player, the player's sense of tension is increased. Can do.

  A plurality of second specific winning ports (for example, a valid time extension port 186 and a valid time shortening port 188) are provided in the game area (102), and a plurality of valid period control means (230) are provided in the second specific prize port. The amount of change in the length of the validity period may be controlled according to which of the winning holes (for example, the validity time extension opening 186 and the validity time shortening opening 188) the game ball enters.

  According to this aspect, the degree of extension and shortening of the effective period varies depending on which of the plurality of second specific winning ports the game ball falls into. For example, by providing a second specific prize opening which is advantageous to a player whose validity period is extended or a second specific prize opening which is disadvantageous to a player whose validity period is shortened, Tensions for games can be further increased. Further, by arranging the second prize opening in the game area so that the player can selectively drop the game balls with respect to the plurality of second specific prize openings according to the batting adjustment, Can increase the technical intervention of

  A route selection device (for example, a route) that can distribute a game ball to either a first specific winning port (for example, a specific port 184) or a second specific winning port (for example, an effective time extension port 186 or an effective time shortening port 188). A selection device 182 and a three-hole cleon 194) may further be provided.

  This route selection device affects whether the player benefits or loses in relation to the selection of a specific winning opening. Increase the player's interest in the game ball to be dropped into the first specific winning port and the second specific winning port, or to which second specific winning port, and unpredictability of the game result There is also an effect of increasing.

  Another aspect of the present invention is also a ball game machine (10). The ball game machine (10) may be a game board (100) in which a game area (102) is formed, and a specific winning opening (for example, a specific opening 184) provided at a predetermined position in the game area (102). , The specific winning device 118 may be widely used), a start winning opening (112) provided at a predetermined position in the game area (102), and a game ball falling into the starting winning opening (112) as an opportunity. The validity determination means (for example, start winning determination means 214) that executes a lottery with a predetermined probability to determine whether or not to set the value, and whether or not to change the probability of winning in the lottery to a higher probability than usual Probability change determination means for determining (for example, first symbol probability change determination means 218) and effective period control means (2 for initial setting a predetermined period as an effective period when the lottery result is a win. 0) and a special game state advantageous to the player is triggered by the drop of the game ball into the specific winning opening (for example, the specific opening 184 or the specific winning device 118 may be widely used) within the effective period. Special game transfer means (for example, special game control means 208). The effective period control means (230) initially sets the effective time based on whether or not the probability of winning in the lottery varies to a higher probability than usual.

  In the so-called probability change state, the probability of winning the lottery increases, but the length of the effective period is also changed depending on whether the probability change state or the non-probability change normal state. For example, in the probability variation state, if the length of the effective period is set longer than that in the non-probability variation state, there are two types of profit opportunities for the player. This is effective in increasing the player's interest in whether or not to shift to a certain change state.

  You may further provide the effective time alerting | reporting means (For example, alerting | reporting control means 206) which alert | reports the time passage in an effective period to a player.

  By notifying the player of the remaining time of the effective period or the elapsed time of the effective period, a sense of tension can be further evoked in the player psychology during the effective period. Thereby, it is possible to improve the entertainment of the game especially during the effective period. As the notification means, for example, the remaining time may be displayed in a countdown manner on the screen, or the player may be notified by voice such as “the validity period will expire in the remaining 10 seconds”. Good.

  According to the present invention, it is possible to enhance the interest of the ball game machine with respect to the transition to the special game.

  FIG. 1 shows a basic structure on the front side of a pachinko gaming machine 10. The pachinko gaming machine 10 is mainly composed of a gaming machine frame and a gaming board surface. The gaming machine frame of the pachinko gaming machine 10 includes an outer frame 11, a front frame 12, a transparent plate 13, a door 14, an upper ball dish 15, a lower ball dish 16, and a launch handle 17. The outer frame 11 has an opening and is a frame for fixing the pachinko gaming machine 10 to a position where it should be installed. The front frame 12 is a frame body that aligns with the opening portion of the outer frame 11, and is attached to the outer frame 11 so as to be opened and closed by a hinge mechanism (not shown). The front frame 12 includes a mechanism for launching a game ball, a mechanism for detachably storing a game board, a mechanism for guiding or collecting the game ball, and the like. The speaker 152 outputs sound according to the gaming state.

  The transparent plate 13 is a plate through which a game area of a game board formed of glass or the like can be seen through. The door 14 supports the transparent plate 13. The door 14 is attached to the front frame 12 so as to be openable and closable by a hinge mechanism (not shown). The upper ball tray 15 has a mechanism for storing game balls, sending out the game balls to the launch rail, and extracting the game balls to the lower ball tray 16. The lower ball tray 16 has a mechanism for storing and extracting game balls. When the player rotates the launch handle 17, the game ball is launched.

  FIG. 2 is a diagram showing the structure of the game board 100. The gaming board 100 has an out port 174, a main symbol display device 124, a winning device 110, a big winning port 104, a normal symbol display device 140, an operating port 142, on a gaming area 102 partitioned by an outer rail 170 and an inner rail 172. It includes an effective period end port 146, a windmill 154, and a general winning port 156. In the game area 102, a plurality of game nails (not shown) are installed. The game effect lamp 150 blinks according to the game state. The big winning opening 104 includes a winning detection detector 106 for detecting the entry of a game ball and a big winning opening solenoid 108 for expanding the big winning opening. The winning device 110 includes a start port 112 and a specific winning device 118. The start port 112 includes a start winning detector 114 for detecting the entrance of a game ball and a normal electric accessory solenoid 116 for expanding the start port. The specific winning device 118 includes a specific mouth passing ball collection port 176. Part of the game balls that have passed through the start port 112 and dropped into the specific winning device 118 drop into the specific port passing ball collection port 176.

  When the player turns the launch handle 17 by hand, the game balls stored in the upper ball tray 15 are guided one by one to the inner rail 172 and the outer rail 170 with a strength corresponding to the turning angle, thereby playing the game area. To 102. When the player fixes the rotation position of the firing handle 17 by hand, the game ball is repeatedly fired at regular time intervals. The game ball launched to the upper part of the game area 102 falls in a direction according to how it hits while hitting a plurality of game nails and the windmill 154. When a game ball falls into each of the general winning ports 156, the start port 112, and the big winning port 104, the winning ball corresponding to the type of the winning port is paid out to the upper ball plate 15 or the lower ball plate 16. A game ball dropped into each winning opening such as the general winning opening 156 is processed as a safe ball, and a gaming ball flowing into the out opening 174 is processed as an out ball. Note that each winning opening includes a gate type through which a game ball passes, and “incoming” in this specification includes “passing”.

  A lottery (hereinafter referred to as “effective period lottery”) is executed when the game ball falls into the start opening 112. If the result of the effective period lottery is a win, a predetermined length of time called effective time is set and counting of elapsed time is started. Hereinafter, the period until the remaining effective time becomes zero after the effective time is set is referred to as “effective period”. Up to four results of the validity period lottery are put on hold. The symbol variation display during the lottery will be described in detail later.

  The game ball that has passed through the start opening 112 falls into the specific winning device 118. A game ball that has dropped into the specific winning device 118 is processed as a safe ball regardless of whether or not it is within the valid period. The specific winning device 118 has three holes inside, and the game ball falls into one of these three holes. A game ball dropped into two of these three holes is recovered as it is as a game-completed ball. When the time change area passage detector 122 detects that the game ball has fallen into these holes within the effective period, the remaining effective time is further increased or decreased.

  The game ball that has dropped into the remaining one of these three holes falls into the specific-portion passing ball collection port 176 and is collected as a played ball at the specific-portion passing ball collection port 176. The special area passage detector 120 detects this. When the game ball falls into the specific mouth passing ball collection port 176 within the valid period, a lottery (hereinafter referred to as “special game lottery”) is further executed. If it is a win, it shifts to a special game. Up to four results of special game lottery are put on hold.

  If the game ball falls into the specific prize winning device 118 within the valid period, it will trigger the expansion or contraction of the valid time or the special game lottery. However, if the game ball falls into the special prize winning device 118 outside the valid period, Similar to the general winning, only a predetermined number of prize balls are paid out to the upper ball tray 15 or the lower ball tray 16. Thus, the role of the specific winning device 118 changes depending on whether it is within the valid period or outside the valid period. For this reason, the limited space of the game area 102 can be effectively utilized. A mechanism for collecting these game balls dropped into the specific winning device 118 will be described later in detail with reference to FIGS.

  If a game ball enters the valid period end port 146 within the valid period, the valid period is forcibly terminated regardless of the remaining valid time. The falling of the game ball into the effective period end port 146 is detected by the effective period end port passage detector 148. The player needs to adjust the hitting ball so that the gaming ball does not fall into the effective period end port 146 during the effective period. The term of validity ending port 146 enhances the technical intervention to the game.

  The main symbol display device 124 includes a remaining effective time display unit 132, a special game lottery hold display unit 130, and a main screen 178. The remaining valid time display unit 132 counts down the remaining valid time during the valid period. The remaining effective time may be announced to the player by voice, for example, “It will be finished in 10 seconds. 9, 8, 7,...”. Thereby, it is possible to produce an effect that further enhances the player's sense of tension within the effective period. The special game lottery hold display section 130 displays the number of holds as a result of the special game lottery. The main screen 178 variably displays the first symbol and the second symbol in the first region 126 and the second region 128 based on the variation start condition set for each. Here, the first symbol is a symbol for indicating whether or not to generate a hit according to the result of the validity period lottery. The second symbol is a symbol for indicating whether or not to generate a win according to the result of the special game lottery. The effective period lottery hold display unit 158 displays the number of holds as a result of the effective period lottery. The main screen 178 is composed of a liquid crystal display, for example. The main screen 178 displays, in the first area 126 and the second area 128, moving images of a plurality of rows of symbol variations that simulate a slot machine game as the first symbol and the second symbol, respectively.

  When the game ball falls into the start opening 112, the start winning detector 114 detects this. Triggered by this detection, the first symbol in the first area 126 is stopped after being displayed for a predetermined time. When the first symbol at the time of stoppage is a symbol indicating a win, an effective period is set. At this time, the first symbol imitating the game of the slot machine takes a form in which three symbols are matched. If the game ball falls into the specific winning device 118 within the valid period and then falls into the specific mouth passing ball collection port 176, the special area passage detector 120 detects this. With this detection as a trigger, the second symbol in the second area 128 is variably displayed for a predetermined time and then stopped. When the second symbol at the time of stoppage is a symbol indicating a so-called “hit”, the game shifts to a special game, and the opening / closing operation of the big winning opening 104 is started. At this time, the second symbol imitating the slot machine game takes a display mode in which the three symbols are matched.

  The start opening 112 and the big winning opening 104 are arranged in the game area 102 as shown in the figure, and are configured as variable entry holes that can be changed between an open state and a closed state. In addition, the closed state includes not only a state where the game ball cannot be dropped in due to being completely closed, but also a state where the entrance area of the variable entrance is set small and the game ball is difficult to enter. Shall be. The starting port 112 is normally formed of an electric accessory, and its inlet can be expanded. When the ordinary electric accessory is in the expanded state, the game ball easily falls into the start port 112. The big winning opening 104 is a horizontal rectangular winning opening that becomes an open state as a “big hit” when the second symbol stops in a specific manner. The big winning opening 104 is provided above the out opening 174. The inside of the big winning opening 104 is divided into a specific area (so-called V zone) and a general area.

  When the second symbol stops in the big hit mode and shifts to a special game, the big winning opening 104 is temporarily closed after being opened for about 30 seconds or after 10 or more game balls are dropped. If at least one game ball falls into a specific area while the big prize opening 104 is open, the big prize opening 104 is opened again. In this way, the opening / closing of the special winning opening 104 is repeated a predetermined number of times, for example, 15 times, on condition that at least one game ball falls into the specific area while the special winning opening 104 is opened once.

  When the game ball passes through the operation port 142 within the effective period, the operation port passage detector 144 detects this. In response to this detection, a lottery (hereinafter referred to as “normal symbol lottery”) is executed. In order to display the lottery result, a symbol called a normal symbol is variably displayed on the normal symbol display device 140 for a predetermined time. The normal symbol lottery is won with a probability of about 50%, and the start port 112 is expanded after the variation of the normal symbol is stopped. When the normal symbol lottery is won, the game ball easily falls into the start port 112. As a result, the game ball easily falls into the specific-portion passing ball collection port 176. In the present embodiment, the normal symbol lottery is executed only within the valid period. In addition, the normal symbol lottery shall not be suspended. However, this does not limit the scope of the present invention. As another embodiment of the present invention, the normal symbol lottery may be executed outside the valid period, or the normal symbol lottery may be held for a predetermined number.

  FIG. 3 shows a basic structure on the back side of the pachinko gaming machine 10. The power switch 40 is a switch for turning on / off the power of the pachinko gaming machine 10. The main board 41 controls the overall operation of the pachinko gaming machine 10 and processes all gaming operations such as lottery when winning the start port 112 in particular. The sub board 49 includes a liquid crystal unit 42 and controls display contents on the main screen 178. The sub board 49 changes the display contents according to the lottery result by the main board 41 in particular. The payout unit 43 pays out the game balls supplied from the winning ball tank 44 to the upper ball tray 15 in accordance with winning in each winning opening. The payout control board 45 controls the payout operation by the payout unit 43. The launching device 46 launches the stored balls in the upper ball tray 15 to the game area 102 one by one. The launch control board 47 controls the launch operation of the launch device 46. The power supply unit 48 supplies power to each part of the pachinko gaming machine 10.

  FIG. 4 is a diagram showing the mechanism of the specific winning device 118. FIG. 4A is an enlarged front view of the specific winning device 118. The game ball that has passed through the start port 112 falls into the specific winning device 118 from the entrance port 180. The game ball follows one of the two routes by the route selection device 182 and falls into the three-hole cron 194. The three-hole crew 194 has three holes, a specific port 184, an effective time extension port 186, and an effective time shortening port 188. After the game ball rotates in the three-hole cron 194, it finally falls into one of these three holes.

  FIG. 4B is a plan cross-sectional view of the specific winning device 118 mainly showing the path after the game ball has passed through the three-hole croon 194. The game ball dropped into the effective time extension port 186 is collected through the first discharge port 192 as a game-completed ball through the guide rib 190. The time extension region passage detector 162 detects the falling of the game ball into the effective time extension port 186. The game ball that has entered the effective time shortening port 188 is also collected through the second discharge port 196 as a game-completed ball through the guide rib 190. The time shortening region passage detector 164 detects the entry of the game ball into the effective time shortening port 188. The game ball dropped into the specific port 184 passes through the guide rib 190 and falls into the specific port passing ball collection port 176 below. The special area passage detector 120 detects the drop. If a game ball falls into the specific mouth passing ball collection port 176 within the valid period, a special game lottery is executed with this as a trigger.

  If the game ball falls into the valid time extension port 186 within the valid period, the remaining valid time is added for 5 seconds. If the game ball falls into the effective time shortening port 188 within the effective period, the remaining effective time is subtracted by 5 seconds. In other words, within the effective period, if the game ball falls into the specific opening 184 and the effective time extension opening 186, the beneficiary opportunity is expanded, but if the game ball enters the effective time shortening opening 188, the beneficiary opportunity is reduced. It will be. Thereby, a player's interest can be heightened with respect to which of these three holes a game ball falls. In addition, since the game ball that has passed through the start port 112 falls into any one of these three holes, the game situation can be greatly changed by one game ball. For example, when one game ball passes through the start port 112 and the specific port 184 and falls into the specific port passing ball collection port 176, the special game is changed from the normal gaming state through the variation of the first symbol and the second symbol. It can shift to a gaming state. As a result, it is possible to provide a game whose situation changes dynamically.

  FIG. 5 is an explanatory view showing the mechanism of the specific winning device 118 from the side. FIG. 5A is an explanatory diagram showing a side cross section of the specific winning device 118 for showing a mechanism for collecting the game balls dropped into the specific port 184. The left side is the player side and the right side is the back side of the gaming machine. The game balls dropped from the entrance port 180 are distributed by the route selection device 182 and then fall onto the three-hole crew 194. When the specific winning solenoid 160 is excited, the inclination rate of the three-hole crew 194 changes. In the figure, the specific winning solenoid 160 is excited, and the three-hole crew 194 is tilted toward the player side. Therefore, the game ball is easier to drop into the specific port 184 than usual. The game ball dropped into the specific port 184 is collected as a game-completed ball by the specific port passing ball collection port 176.

  FIG. 5B is an explanatory view showing a side cross section of the specific winning device 118 for showing a mechanism for collecting the game balls dropped into the effective time extension port 186. This figure shows a case where the specific winning solenoid 160 is not excited and the three-hole crew 194 is not inclined. The game balls that have entered the effective time extension port 186 are collected by the first discharge port 192. The time extension region passage detector 162 detects the game ball passing through the first outlet 192. The same applies to the mechanism for collecting the game balls dropped into the effective time shortening port 188. The game balls that have entered the effective time shortening port 188 are collected by the second discharge port 196. The time shortening region passage detector 164 detects that the game ball passes through the second outlet 196.

  FIG. 6 shows functional blocks of the pachinko gaming machine 10. The game control device 200, the prize winning port 104, the winning device 110, the main symbol display device 124, the normal symbol display device 140, the operation port 142, the effective period end port 146, the game effect lamp 150 and the speaker 152 shown in FIG. It is electrically connected to send and receive control signals.

The first symbol variation control means 216 controls the variation display of the first symbol associated with the result of the effective period lottery. The first symbol variation holding means 234 holds up to four valid period lottery results. The first symbol probability change determination means 218 determines whether or not to change the winning probability of the effective period lottery to a high probability.

  When the special area passing detector 120 is notified that the game ball has passed the specific port 184 during the effective period, the specific winning determination means 222 acquires a random number and executes a special game lottery based on the random number. To do. The second symbol variation control means 224 controls the variation display of the second symbol associated with the result of the special game lottery. The second symbol variation holding means 226 holds up to four special game lottery results. The second symbol probability change determining means 228 determines whether or not to change the winning probability of the special game lottery to a high probability. A maximum of eight results of the validity period lottery and the special game lottery are held. Therefore, it is difficult to become “a state in which no hold is made”, and it is effective in inducing a sense that the player has an expanded beneficiary opportunity.

  The drop-in rate control means 232 controls the probability that a game ball will drop into the specific mouth passing ball collection port 176 within the effective period. If the normal symbol lottery is won, the drop-in rate control means 232 instructs the specific winning solenoid 160 to incline the three-hole crew 194 so that the game ball can easily drop into the specific-port passing ball collection port 176. Let Alternatively, the drop-in rate control means 232 may control the game balls that have dropped into the effective time extension port 186 in addition to the specific port 184 to drop into the specific port passing ball collection port 176. The effective time calculation means 236 calculates the length of the effective time according to the detection signals from the special region passage detector 120 and the time change region passage detector 122. The success / failure determination unit 202 executes each of these processes according to various flag information related to the gaming state managed by the gaming state determination unit 204. Specific processing will be described later in detail with reference to FIG.

  When the operating port passage detector 144 is notified by the operating port passage detector 144 that the game ball has passed through the operating port 142 during the effective period, the operating port passage determining means 240 obtains a random number and performs a normal symbol lottery based on the random number. Execute. The normal symbol fluctuation control means 242 controls the fluctuation display of the normal symbol accompanying the result of the normal symbol lottery. The variable winning portion control means 244 instructs the ordinary electric accessory solenoid 116 to widen the start port 112. If the result of the normal symbol lottery is a win, the start port 112 is expanded longer.

  The display control means 246 displays the game status to the player by sending control signals to the main symbol display device 124, the normal symbol display device 140, and the game effect lamp 150. The voice control unit 248 sends a control signal to the speaker 152 to notify the player of the gaming situation by voice. The special game transition determining means 250 determines whether or not to shift to a special game according to the result of the special game lottery. The special game execution means 252 executes the special game according to the determination result of the special game transition determination means 250.

  FIG. 7 is a flowchart showing an overall processing process of the game. The processing shown in the figure is executed based on periodic polling and occurrence of various events. First, the success / failure determination means 202 determines whether the game ball hit in the game area 102 has dropped into any winning opening (S10). When the game ball falls into each winning opening that triggers the lottery, the winning / failing determination unit 202 executes a hit determination process for executing various lotteries based on the winning (S12). The special game control means 208 executes special game execution determination processing to determine whether or not the special game can be executed based on the determination result in S12 (S14). The effective period lottery determination means 212 executes a first probability variation game control process in order to determine whether or not the probability that the first symbol is won should be changed to a high probability (S16). The special game lottery determination means 220 executes a second probability variation game control process in order to determine whether or not the probability that the second symbol is a win should be changed to a high probability (S18). The valid period control unit 230 performs an update process on the remaining valid time (S20). Among these processes, the specific contents of each process from S12 to S18 will be described in detail later in connection with FIG.

  FIG. 8 is a flowchart showing in detail the hit determination process in S12 of FIG. First, the valid period lottery determination unit 212 executes a valid period lottery determination process regarding the valid period lottery (S22). The effective period control means 230 executes the specific winning award enabling process for effective period control including whether or not the effective period is set based on the result of the effective period lottery in S22 (S24). The special game lottery determination means 220 executes a special game lottery determination process regarding the special game lottery (S26). The specific contents of each of these processes will be described in detail later with reference to FIGS.

  FIG. 9 is a flowchart showing in detail the validity period lottery determination process in S22 of FIG. The start winning determination means 214 determines whether or not the game ball has passed through the start opening 112 based on the detection information from the start winning detector 114 (S28). If no passage is detected (N in S28), the process is skipped to S36. If the passage is detected (Y in S28), the valid period lottery determination means 212 determines whether the number of pending validity period lottery results is within the upper limit of 4 (S30). If it is not within the upper limit (N in S30), the process is skipped to S36. If it is within the upper limit (Y in S30), the first symbol variation holding means 234 adds 1 as the number of held balls regarding the effective period lottery (S32). The start winning determination means 214 performs a validity period lottery and acquires the first symbol winning random number (S34). The effective period lottery determination means 212 stores the first symbol winning random number as a holding ball.

  The first symbol fluctuation control means 216 detects whether the first symbol fluctuation holding means 234 holds the first symbol winning random number (S36). If it is not on hold (N in S36), the effective period lottery determination process in S22 ends. If it is on hold (Y in S36), the first symbol variation control means 216 determines whether or not the first symbol can be varied (S38). The first symbol is not variably displayed during the effective period and special game state during the variation of the second symbol. If the first symbol is already changing, the next change cannot be executed until the change is completed. In other words, the execution of the special game has the highest priority, and the next priority is the variation display of the second symbol. In the first symbol variation, the execution priority is set lower than these. The first symbol variation control means 216 determines whether or not the first symbol variation can be started based on the gaming state managed by the gaming state determination unit 204.

  If it is impossible to start changing the first symbol (N in S38), the effective period lottery determination process in S22 ends. If the variation of the first symbol can be started (Y in S38), the first symbol variation holding means 234 subtracts 1 as the number of retained balls (S40). The start winning determination unit 214 determines whether or not the first probability variation flag for determining whether or not the probability of winning the effective period lottery should be changed to a high probability is turned on (S42). In the initial state, the first probability variation flag is set to off. If it is turned on (Y in S42), the start winning determination means 214 reads a determination table (hereinafter simply referred to as “first high probability table”) on which the effective period lottery is won with high probability (S44). If it is not turned on (N in S42), the start winning determination means 214 reads a determination table (hereinafter simply referred to as "first normal probability table") on which the effective period lottery is won with a normal probability (S46). In the case of the first high probability table, a random number of about 1/30 of the first symbol winning random numbers that can be acquired in S34 is determined to be a hit. On the other hand, in the case of the first normal probability table, a random number of about 1/90 of the first symbol winning random numbers is determined to be a hit.

  The start winning determination means 214 refers to the determination table read in S44 or S46, and determines whether the first symbol winning random number acquired in S34 is a winning random number (S48). If it is a win (Y in S48), the first symbol fluctuation control means 216 sets the winning symbol so that the fluctuation display by the first symbol ends in the hit mode (S50). Specifically, it is set so that the three symbols are matched in the first area 126 and stopped and displayed, such as “333” and “777”. Which symbol is matched, such as “3” and “7” here, is determined based on the first symbol winning random number. If it is off (N in S48), the first symbol fluctuation control means 216 sets the off symbol so that the fluctuation display by the first symbol ends in the off mode (S52). Specifically, it is set so that the three symbols in the first area 126 are stopped and displayed so as not to match, such as “337” and “374”.

  The first symbol variation control means 216 selects the variation pattern of the first symbol in accordance with these set symbols (S54). The first symbol variation control means 216 displays the first symbol variably in the first region 126 based on the selected variation pattern (S56). After the end of the variable display, the symbol set in S50 or S52 is displayed in a stop mode.

  FIG. 10 is a flowchart showing in detail the specific winning opening enabling process in S24 of FIG. First, the effective period control means 230 determines whether or not the variation of the first symbol has been completed (S58). If the first symbol is in a variable display (N of S58), the process is skipped to S70. If the variation display of the first symbol has been completed (Y of S58), the effective period control means 230 detects whether or not the first symbol winning random number has been determined to be win for the variation display (S60). If it is off (N in S60), the process is skipped to S70. If it is a win (Y in S60), the valid time calculating means 236 determines whether or not the first probability variation flag is turned on (S62). If it is turned on (Y in S62), the valid time calculating means 236 sets the valid time as 60 seconds (S64). If it is not turned on (N in S62), the valid time calculating means 236 sets the valid time as 20 seconds (S66). That is, when the variation of the first symbol is in a probabilistic state, the player can enjoy the merit that a long effective period is set in addition to the merit of winning with high probability in the effective period lottery. Thereby, it becomes possible to arouse the player's interest in what is called probability change.

  The gaming state determination means 204 turns on a valid period flag indicating that the period is valid (S68). If the flag during the effective period is not turned on in the processing stage of S70 which is the next process (N of S70), the specific winning a prize enabling process of S24 ends. For example, if the first symbol is changing, the process proceeds to S70 while the valid period flag remains off. If the flag during the effective period is turned on (Y in S70), the operation port passage determination means 240 determines whether the game ball has passed through the operation port 142 based on the detection information from the operation port passage detector 144. (S72). If the game ball has not passed through the operating port 142 (N in S72), the process is skipped to the next S92 shown in FIG. If it has passed (Y of S72), the normal symbol variation control means 242 determines whether or not the normal symbol variation display is permitted (S74). If the normal symbol is already in the variable display, the new normal symbol variable display is not permitted (N in S74), and the process is skipped to S92 shown in FIG. If the normal symbol can be variably displayed (Y in S74), the operation port passage determining means 240 acquires the normal symbol random number as the normal symbol lottery (S76).

  FIG. 11 is a flowchart showing in detail the specific winning opening enabling process after S76 in FIG. The operating port passage determination means 240 determines whether or not the normal symbol random number acquired in S76 is a win with reference to the normal symbol hit determination table (S78). If it is a win (Y in S78), the normal symbol fluctuation control means 242 sets the win symbol so that the fluctuation display by the normal symbol ends in the hit mode (S80). At this time, the drop-in rate control means 232 may perform control so that the game ball is likely to drop into the specific-portion passing ball collection port 176 temporarily. If it is off (N in S78), the normal symbol fluctuation control means 242 sets the off symbol so that the fluctuation display by the normal symbol ends in the off mode (S82). As the normal symbols, “−” and “7” are cyclically displayed on the normal symbol display device 140, and then the symbols set in S80 or S82 are displayed in a stopped manner. When stopped at “-”, the normal symbol lottery is off, and when stopped at “7”, it is a win.

  Next, the normal symbol fluctuation control means 242 determines whether the stop symbol of the first symbol is a specific hit (S84). In S84, the first symbol is stopped in a winning manner. At this time, for example, a case where the vehicle stops at “333” or “777” is called “specific hit” and is distinguished from other hits. If it is a specific hit (Y in S84), the normal symbol variation control means 242 sets the normal symbol variation display time to 5 seconds (S86). If it is not a specific hit (N in S84), the normal symbol fluctuation control means 242 sets the normal symbol fluctuation display time to 7 seconds (S88).

  The normal symbol variation control means 242 starts displaying the variation of the normal symbol based on the symbol set in S80 or S82 and the variation time set in S86 or S88 (S90). The normal symbol variation control means 242 determines whether or not the normal symbol variation display has been completed (S92). If not in the finished state (N in S92), the process is skipped to the next S106 shown in FIG. If the normal symbol variation display has been completed (Y in S92), the variable winning portion control means 244 detects whether or not the normal symbol random number is determined to be win for the variation display (S94). If it is off (N in S94), the process is skipped to S106 shown in FIG. If it is a win (Y in S94), the variable winning portion control means 244 determines whether or not the first symbol is a specific win (S96). If it is a specific hit (Y in S96), the variable winning portion control means 244 widens the start port 112 for 2 seconds (S98). If it is not a specific hit (N in S96), the variable winning portion control means 244 widens the start port 112 for 1 second (S100). That is, when the first symbol is a specific hit, the time for the start port 112 to expand is set to 2 seconds with respect to the normal symbol fluctuation time of 5 seconds, compared to the case where it is not a specific hit. This makes it easier for the game ball to drop into the winning device 110.

  The valid time calculating means 236 determines whether or not the game ball is passing through the valid period end opening 146 based on the detection information from the valid period end opening detector 148 (S102). If it has not passed (N of S102), S104 is skipped. If it has passed (Y of S102), the valid time calculating means 236 sets the remaining valid time to zero (S104).

  FIG. 12 is a flowchart showing in detail the specific winning opening enabling process in S104 and after in FIG. The valid time calculating means 236 determines whether or not the game ball has passed through the valid time extension port 186 (S106). If it has not passed (N of S106), S108 is skipped. If it has passed (Y in S106), the valid time calculating means 236 adds 5 seconds to the remaining valid time (S108). The valid time calculating means 236 determines whether or not the game ball has passed through the valid time shortening port 188 (S110). If it has not passed (N of S110), S112 is skipped. If it has passed (Y of S110), the valid time calculating means 236 subtracts 5 seconds from the remaining valid time (S112).

  The specific winning determination means 222 determines whether or not the game ball has passed through the specific port 184 based on detection information from the special area passage detector 120 (S114). If it has not passed (N of S114), S116 is skipped. If it has passed (Y of S114), the game state determination means 204 turns on a specific winning flag which is a precondition for executing the special game lottery (S116). If the remaining valid time is greater than zero (N in S118), the specific winning opening validation process in S24 ends. If the remaining effective time is less than or equal to zero (Y in S118), the effective period control means 230 determines whether or not the normal symbol variation has ended and the start port 112 has not expanded (S120). If this condition is not satisfied (N in S120), the specific winning opening validation process in S24 ends. If it is satisfied (Y in S120), the effective period control means 230 sets 3 seconds as a grace period and starts counting (S122). This is to ensure time for the game balls remaining in the specific winning device 118 to be discharged out of the specific winning device 118. If the remaining grace time is not zero (N in S124), the specific winning opening enabling process in S24 ends. If it is zero (Y of S124), the gaming state determination means 204 turns off the flag during the effective period (S126). The gaming state determination unit 204 turns on an effective period end flag indicating that the effective period has ended (S128).

  FIG. 13 is a flowchart showing in detail the special game lottery determination process in S26 of FIG. First, the specific winning determination means 222 determines whether or not the specific winning flag is turned on (S130). If it is not turned on (N in S130), the process is skipped to S140. If it is on (Y of S130). The gaming state determination means 204 turns off the specific winning flag (S132). The specific winning determination means 222 determines whether the number of reserved special game lottery results is within the upper limit of 4 (S134). If not within the upper limit (N in S134), the process is skipped to S140. If it is within the upper limit (Y in S134), the second symbol variation holding means 226 adds 1 as the number of held balls related to the special game lottery (S136). The specific winning determination means 222 acquires the second symbol winning random number as the special game lottery (S138). The second symbol variation holding means 226 stores this random number as a holding ball.

  The second symbol fluctuation control means 224 detects whether the second symbol fluctuation holding means 226 holds the second symbol winning random number (S140). If not on hold (N in S140), the special game lottery determination process in S26 ends. If it is on hold (Y in S140), the second symbol variation control means 224 determines whether the second symbol can be varied (S142). The second symbol is not variably displayed in the special game state. If the second symbol is already changing, the next change cannot be executed until the change ends. The second symbol variation control means 224 determines whether or not the second symbol variation can be started based on the gaming state managed by the gaming state determination unit 204.

  If the variation of the second symbol cannot be started (N in S142), the special game lottery determination process in S26 ends. If the variation of the second symbol can be started (Y in S142), the second symbol variation holding means 226 subtracts 1 as the number of the retaining balls (S144). The second symbol probability change determination means 228 determines whether the second probability change flag serving as an index for determining whether or not the probability of winning the special game lottery should be changed to a high probability is turned on (S146). In the initial state, the second probability variation flag is set to off. If it is turned on (Y in S146), the specific winning determination means 222 reads a determination table (hereinafter, simply referred to as “second high probability table”) on which the special game lottery is won with high probability (S148). If it is not turned on (N in S146), the specific winning determination means 222 reads a determination table (hereinafter simply referred to as “second normal probability table”) on which the special game lottery is won with a normal probability (S150). In the case of the second high probability table, it is a table that determines that about 1/5 of the second symbol winning random numbers that can be acquired in S138 is a hit. On the other hand, in the case of the second normal probability table, a random number of about 1/15 of the second symbol winning random numbers is used as the winning table. The setting of the second probability variation flag will be described in detail with reference to FIG.

  The specific winning determination means 222 refers to the determination table read in S148 or S150 and determines whether the second symbol winning random number acquired in S138 is a winning random number (S152). If it is a win (Y in S152), the second symbol fluctuation control means 224 sets the winning symbol so that the fluctuation display by the second symbol ends in the hit mode (S154). Specifically, it is set so that the three symbols are matched in the second area 128 and stopped and displayed, such as “333” and “777”. Which symbol is matched, such as “3” and “7” here, is determined based on the second symbol winning random number. If it is off (N in S152), the second symbol fluctuation holding means 226 sets the off symbol so that the fluctuation display by the second symbol ends in the off mode (S156). Specifically, it is set so that the three symbols are stopped and displayed in the second area 128 so that they do not match, such as “337” and “374”.

  The second symbol variation control means 224 selects the variation pattern of the second symbol in accordance with these set symbols (S158). The second symbol variation control means 224 displays the second symbol in the second region 128 variably based on the selected variation pattern (S160). After the end of the variable display, the symbol set in S154 or S156 is displayed in a stop mode.

  FIG. 14 is a flowchart showing in detail the special game execution determination process in S14 of FIG. The special game transition determination means 250 determines whether or not the variation display of the second symbol has been completed (S162). If not completed (N in S162), the process is skipped to S168. If completed (Y in S162), the special game transition determination means 250 determines whether or not the second symbol winning random number is a win for the change (S164). If it is off (N in S164), the process is skipped to S168. If it is a win (Y in S164), the gaming state determination means 204 turns on a special gaming flag for instructing the transition to the special gaming state (S166).

  If the special game flag is not turned on (N in S168), S170 is skipped. If it is turned on (Y in S168), the special game executing means 252 starts executing the special game (S170). The gaming state determination unit 204 determines whether the special game has ended (S172). If not finished (N in S172), the special game execution determination process in S14 is finished. If the special game has ended (Y in S172), the gaming state determination means 204 turns on the second probability variation determination flag, which is a precondition for determining whether to change to a high winning probability in the next special game lottery (S174). ).

  FIG. 15 is a flowchart showing in detail the first symbol probability variation game control process in S16 of FIG. First, the first symbol probability change determination means 218 determines whether the valid period end flag is turned on (S176). If it is not turned on (N in S176), the first symbol probability variation game control process in S16 ends. If it is turned on (Y in S176), the first symbol probability change determining means 218 reads the stop symbol in the variation display of the first symbol (S178). The first symbol probability change determining means 218 determines whether or not the read symbol is a symbol assigned in advance as a probability variable symbol (S180). If it is a probability variation symbol (Y of S180), the gaming state determination means 204 turns on the first probability variation flag (S182). If it is not the probability variation symbol (N of S180), the gaming state determination means 204 turns off the first probability variation flag (S184). The gaming state determination unit 204 turns off the valid period end flag (S186). The first probability variation flag is a determination condition flag in S42 of FIG. 9 and S62 of FIG.

  FIG. 16 is a flowchart showing in detail the second symbol probability variation game control process in S18 of FIG. First, the second symbol probability change determination means 228 determines whether the second probability change determination flag is turned on (S188). If it is not turned on (N in S188), the second symbol probability variation game control process in S18 ends. If it is turned on (Y in S188), the second symbol probability change determining means 228 reads the stop symbol in the variation display of the second symbol (S190). The second symbol probability change determining means 228 determines whether or not the read symbol is a symbol assigned in advance as a probability variable symbol (S192). If it is a probability variation symbol (Y in S192), the gaming state determination means 204 turns on the second probability variation flag (S194). If it is not a probability variation symbol (N in S192), the gaming state determination means 204 turns off the second probability variation flag (S196). The second probability variation flag is a precondition for the determination in S146 of FIG.

  FIG. 17 is a timing chart showing a game process in the pachinko gaming machine 10. The horizontal axis shows time, and the timing charts arranged in 13 stages are, in order from the top, the presence or absence of the passage of the start port 112 by the game ball, the presence or absence of the first symbol variation, the presence or absence of the passage of the operation port 142 by the game ball, Presence / absence of normal symbol variation, presence / absence of effective time setting, presence / absence of passage of effective time extension port 186 by game ball, presence / absence of passage of effective time shortening port 188 by game ball, presence / absence of passage of specific port 184 by game ball, It shows the presence / absence of the second symbol variation, the presence / absence of the special game, the presence / absence of the passing through the valid period end detector 148 by the game ball, the state of the first probability variation flag, and the state of the second probability variation flag. Note that this timing chart is an example of a process that can be executed, and it goes without saying that there are various variations depending on the game situation.

The figure shows that the result of the lottery executed when the game ball dropped into the start port 112 at times t ₁ , t ₄ and t ₇ is missed, and the game ball dropped at the start port 112 at time t ₁₀ . The result of the lottery executed with the entry is a win. At time t ₁ of the drawing, a game ball passes through the start hole 112. Accordingly, start winning decision means 214 executes the valid period lottery, the first symbol variation control means 216 from the time t ₂ is varied displays the first symbol. Game ball that has passed through the start hole 112 passes through the effective time extension port 186 at time t _3. The winning processing means 210 pays out a predetermined number of prize balls as a general winning. The game ball is collected as it is through the first discharge port 192.

At time t ₄ , the game ball passes through the start port 112. Game ball is落入the starting opening 112 after passing, in particular opening passing ball collecting port 176 further落入to a specific port 184 at time t _5. The winning processing means 210 pays out a predetermined number of prize balls as a general winning. At time t _4, since the first symbol is being variably displayed, the first symbol variation holding means 234 suspends the validity period lottery. After the variation display of the first pattern is completed, the effective period lottery determination means 212 at time t ₆ performs a validity period lottery, variable display of the first symbol is started. This game ball is collected by the specific-portion passing ball collection port 176.

At time t _7, the game ball passes through the start hole 112, the first symbols are variably displayed from time t _8. The game ball is落入enable time extension opening 186 at time t _9. At time _{t 10,} the game ball passes through the start hole 112, the first symbols are variably displayed from time _{t 11.} The game balls drop into the effective time shortening port 188 at time ₁₂ , and the winning processing means 210 pays out a predetermined number of winning balls as general winnings. Note that the effective period lottery at this time becomes a win, the effective period control unit 230 in the variation after the end of the time t ₁₃ sets a validity period.

At time t ₁₄ within the validity period, the normal symbol lottery when the gaming ball passes through the working port 142 is performed, normal symbol is displayed varies from time t _15. The lottery result is a win, and the start opening 112 expands longer than usual, so that the game ball temporarily falls into the start opening 112 easily. In addition, the drop-in rate control means 232 instructs the specific winning solenoid 160 to incline the three-hole crone 194, so that the game ball can easily drop into the specific port 184.

At time _{t 16,} the game ball passes through the start hole 112. The game ball passes through the effective time extension port 186 at time _{t 17.} As a result, as described in S108, the remaining valid time is extended by 5 seconds. At time t ₁₈ , the game ball passes through the start port 112. This game ball passes through the specific port 184 at time t ₁₉ and falls into the specific port passing ball collection port 176. Accordingly, the specific winning determination means 222 executes a special game lottery. The second symbol variation control means 224 from the time _{t 20} starts the variable display of the second symbol. In the same figure, the result of the lottery is out of place, and the case where the game does not shift to the special game is shown.

At time ₂₁ , the game ball passes through the start port 112. The game ball passes through the particular port 184 again at time _{t 22.} Since at time t ₂₂ and the second symbol is already variable display in the second symbol variation holding means 226 hold the special game lottery. After the end of the variation of the second symbol, the specific winning determination means 222 executes a special game lottery. In the figure, the lottery result is a win, the game in the special game state from the time t ₂₄ after the change completion shows a case where transition.

At a special game after the end of the time t _25, the first symbol probability variation determining means 218 first symbol in the variable display from time t ₁₁ is because a probability variation pattern, to turn on the first probability variation flag. The second symbol probability variation determining means 228 and the second symbol in the variable display from time t ₂₃ does not turn on the second probability variation flag because it was not a probability variation pattern. At time t ₂₆ , the game ball has passed the valid period end port 146. Therefore, lifetime at immediately after time t ₂₇ is forcefully terminated. Going back in time, the game ball passes through the start port 112 at time t ₂₈ during the effective period. The game ball passes through the specific port 184 at time t ₂₉ and falls into the specific port passing ball collection port 176. Accordingly, the special game lottery is performed, from the time t ₃₀ immediately after the special game has ended in the second symbol variable display from time t ₂₄ is started. In the drawing, the lottery result is a win, the special game again from the time t ₃₁ is started. At time t _32, when the special game is finished, based on the result of the validity period lottery which is pending by starting winning at time t _16, the variable display of the first symbol is started anew.

  As shown in this time chart, in the game of the present embodiment, the time for entering a special state such as the variation of the first symbol, the variation of the second symbol, the effective period, and the special game is long. Therefore, compared with the conventional ball game machine, the game state becomes deeper because the game state changes more greatly. Since the transition to the special game is determined by the lottery of the effective period lottery and the special game lottery, the variation of the game is greatly spread, and the game is not easily monotonized. In addition, since the first symbol and the second symbol are variably displayed separately in accordance with these two lotteries, the player can easily understand the game situation. According to the pachinko gaming machine 10 according to the present embodiment, it is possible to provide a player with a deep game in which the user can easily understand the rules and the situation and the variation of the possible game situation is widened.

  In the above, this invention was demonstrated based on the Example. The present invention is not limited to this embodiment, and various modifications thereof are also effective as an embodiment of the present invention.

  In the present embodiment, the case of executing the normal symbol lottery is shown, but the normal symbol lottery itself is not an essential requirement as the scope of the present invention. Further, only one of the effective period may be extended or shortened. For example, the extension degree may be different depending on the holes of the three-hole crew 194, such as a case where the effective period is significantly extended and a case where the effective period is extended to a small width. This is the same even when the effective period is shortened, and the degree of shortening may be different depending on the holes of the three-hole crew 194. The validity period lottery does not necessarily have to be suspended.

  In this embodiment, the first symbol and the second symbol are displayed in different areas of the single main screen 178. However, two screens are provided corresponding to the first symbol and the second symbol, respectively. May be.
