Then, when the second start winning device detection switch 315 detects the entry of a game ball, the “special symbol lottery” described later (hereinafter also referred to as “hit lottery”), similar to the first start winning device 112 described above. And the same prize balls (for example, three game balls) as the first start winning device 112 are paid out.

  In the area on the left side of the game area 106, a normal symbol operation gate 113a having a normal area through which a game ball can pass is provided. The normal symbol operation gate 113a is provided with a gate detection switch 330a (see FIG. 3) for detecting the passage of the game ball. When the gate detection switch 330a detects the passage of the game ball, the “normal symbol of the normal symbol” will be described later. “Lottery” (hereinafter also referred to as “winning lottery”) is performed. Even if a game ball passes through the normal symbol operation gate 113a, a prize ball based on the passage is not paid out.

  In the area on the right side of the game area 106, in order from the top, the normal symbol operating gate 113b having a normal area through which the game ball can pass, the big winning device 117 into which the game ball can enter, and the second start of the game ball A guide plate 116 for guiding to the winning device 115 and a lower display 170 are provided. The configuration of the lower display 170 will be described later. The normal symbol operation gate 113b is provided with a gate detection switch 330b (see FIG. 3) for detecting the passage of a game ball, and has the same function as the normal symbol operation gate 113a.

  The grand prize winning device 117 is a so-called attacker-type electric accessory, and has an open / close door 117b that can be erected from the game board surface side to the glass plate side, and the open / close door 117b is on the game board surface side. It is controlled to move between an open state standing up to a closed state and a closed state buried in the game board surface (FIG. 1 shows the time when the open / close door 117b is controlled in the open state). When the open / close door 117b is erected on the game board surface, it functions as a tray for guiding the game ball into the big prize device 117, and the game ball can enter the big prize device 117.

  The big prize winning device 117 has a configuration capable of displaying a predetermined image on the open / close door 117b. Its configuration will be described later. Further, the big prize device 117 is provided with a big prize device detection switch 317 (see FIG. 3). When this big prize device detection switch 317 detects the entry of a game ball, a predetermined prize ball (for example, 15 pieces). Game balls).

  The guide plate 116 is a plate-like member projecting on the game board surface side, and drops the game ball that has reached the guide plate 116 by dropping the area on the right side of the game area 106 in the direction of the second start winning device 115. It has a downward slope to roll and guide the sphere. That is, the guide plate 116 is a member that facilitates winning of a game ball to the second start winning device 115 when the second start winning device 115 is in the second mode.

  At the bottom of the game area 106, an out port 111 is provided for discharging game balls that have not entered any of the first start winning device 112, the second start winning device 115, and the big winning device 117. It has been.

  An image display device 131 composed of a liquid crystal display (LCD) or the like is provided at a substantially central portion of the game area 106, and this image display device 131 displays an image during standby when no game is being performed. Or displaying an image according to the progress of the game. Among them, a plurality of effect symbols for notifying the lottery result of the special symbol are variably displayed based on the winning of the game ball of the first start prize device 112 and the second start prize device 115, and a combination of specific effect symbols (For example, 777 etc.) is stopped and fixedly displayed, so that the big hit is notified as a special symbol lottery result.

  That is, the special symbols displayed on the first special symbol display device 120 and the second special symbol display device 122, which will be described later, when the game ball wins the first start winning device 112 and the second start winning device 115, respectively. The display is changed in accordance with the change display of the special symbol, and is stopped and displayed in accordance with the stop display of the special symbol after a predetermined fluctuation time has elapsed. That is, the timing of the change display of the effect symbol by the image display device 131 and the change display of the special symbol by the first special symbol display device 120 and the second special symbol display device 122 are synchronized. In addition, by displaying various images, characters, and the like during the variation display of the effect symbols, a high expectation that the player may win a big hit is given to the player. In the present embodiment, the image display device 131 is used as a liquid crystal display device. However, a plasma display, an organic EL display may be used, or a projector, a so-called 7-segment LED, a dot matrix, a rotating drum, or the like. A display device may be used.

  Furthermore, a gimmick 109 as a movable accessory used for various effects is provided on the back of the game board 102. The gimmick 109 is configured to be movable with respect to the game board 102, and performs various effects by moving in a predetermined operation according to the progress of the game by the player. The gimmick 109 is initially arranged on the back surface of the game board 102 and is configured to be movable to the front surface of the screen of the image display device 131.

  On the lower right side of the inner rail 105 b of the game board 102, there are a normal symbol display device 118, a first special symbol display device 120, a second special symbol display device 122, a normal symbol hold indicator 119, and a first special symbol hold indicator 123. A second special symbol hold indicator 124 is provided. The first and second special symbol display devices 120 and 122 indicate that a game ball has entered the first and second start winning device 112 and 115 (first and second start winning device detection switches 312 and 315 to be described later). This is a notification of the jackpot lottery result that was triggered by the fact that a game ball was detected), and is composed of 7-segment LEDs. That is, a plurality of special symbols corresponding to the jackpot lottery result are provided, and the lottery result is displayed by displaying the special symbols corresponding to the jackpot lottery result on the first and second special symbol display devices 120 and 122. The player is notified. For example, “7” is displayed when a big win is won, and “−” is displayed when the player wins.

  Here, “special symbol lottery” means that when a game ball enters the first and second start winning devices 112 and 115, a random number for determining a special symbol is acquired, and the acquired random number is determined in advance. This is a process for determining whether or not a big hit is made by comparing with a value corresponding to the given “big hit”. The jackpot lottery result is not immediately notified to the player, but the special symbols are displayed on the first and second special symbol display devices 120 and 122, and when the predetermined variation time has passed, A special symbol corresponding to the lottery result is fixedly displayed after the stop, and the lottery result is notified to the player.

  The normal symbol display device 118 performs normal symbol lottery triggered by the passing of the game ball through the normal symbol operation gates 113a and 113b (the gate detection switches 330a and 330b described later detect the entry of the game ball). The result is notified, and is composed of one LED (“◎” in the figure). In other words, the normal symbol display device 118 notifies the player of the lottery result by turning on the normal symbol display device 22 when the normal symbol lottery is won. Note that the normal symbol display device 118 is not limited to one LED, and is composed of, for example, a display capable of lighting a predetermined symbol display (for example, a lamp capable of alternately lighting “O” and “X”). May be. If the normal symbol lottery is won, the second start winning device 115 is controlled to the second mode (the movable piece 115b is in the open state) for a predetermined time.

  Here, “ordinary symbol lottery” means that when a game ball passes through the normal symbol operation gates 113a and 113b, a random number for determining a normal symbol is acquired, and the acquired random number is a predetermined “winning”. This is a process for determining whether or not the game is successful by comparing with a value corresponding to. The lottery result of the normal symbol does not immediately notify the lottery result after the game ball passes through the normal symbol operation gates 113a and 113b, and the normal symbol display device 122 displays a fluctuation display such as blinking of the normal symbol. When the predetermined fluctuation time has elapsed, the normal symbol corresponding to the normal symbol lottery result is fixedly displayed (lit or extinguished) after the stop, and the lottery result is notified to the player.

  In addition, while the first special symbol display device 120 or the second special symbol display device 122 is displaying the variation of the special symbol, a game ball enters the first and second start winning devices 112 and 115 and immediately wins a big win. If this is not possible, the right to win the jackpot will be held under certain conditions. More specifically, the random numbers for special symbol determination acquired when a game ball enters the first and second start winning devices 112 and 115 are suspended and stored.

  For this hold, the upper limit hold number is set to four, and the hold number is displayed on the first special symbol hold indicator 123 and the second special symbol hold indicator 124, respectively. Here, in the first and second special symbol hold indicators 123 and 124, when there is one hold, the left LED is lit, when there are two hold, the left and right LEDs are lit, and there are three holds. The left LED blinks and the right LED lights, and when there are four holds, the left and right LEDs blink. The display mode of the first and second special symbol hold indicators 123 and 124 is not limited to this. For example, four LEDs are arranged in a horizontal row, and the LEDs on the left side are lit in order from the occurrence of the hold. Also good.

  As with the special symbol, when the game ball passes through the normal symbol operating gates 113a and 113b and the winning lottery cannot be performed immediately during the normal symbol variation display, The right to draw will be held. More specifically, a random number for determining a normal symbol acquired when a game ball enters the normal symbol operating gates 113a and 113b is held and stored. For this hold, the upper limit hold number is set to four, and the hold number is displayed on the normal symbol hold indicator 119. In addition, the display mode of the normal symbol hold | maintenance display device 119 is based on the display mode of the 1st, 2nd special symbol hold | maintenance display devices 123 and 124 mentioned above, and description here is abbreviate | omitted.

  The first effect button 135 mainly functions as a “decision button”, and the second effect button 136 mainly functions as a “select button”. The first effect button 135 is provided with a first effect button detection switch 335 (see FIG. 3) that detects one pressing operation, and the second effect button 136 includes a second effect that detects a plurality of pressing operations. Button detection switches 336a to 336e (see FIG. 3) are provided. When a player's pressing operation is detected from the first effect button detection switch 335 or the second effect button detection switches 336a to 336e, the image displayed on the image display device 131 is changed. In the present embodiment, the first effect button 135, the first effect button detection switch 335, the second effect button 136, and the second effect button detection switches 336a to 336e are collectively referred to as “input device 137”.

<Description of game content>
Next, with reference to FIG. 1, the main flow of the game in the gaming machine 100 of the present embodiment configured as described above will be described. First, in order to obtain a normal symbol hit and a special symbol hit in the normal game state (a game state other than the big hit and short-time game state described later), the player handles the operation handle as shown by an arrow A in FIG. The left-handed game is performed by reducing the amount of rotation of 107, and the first symbol winning gate 112a positioned at the so-called “kee” at the approximate center of the game area 106 and the normal symbol operating gate 113a positioned at the upper left of the game area 106 Aim and fire a game ball.

  In this normal game state, “right-handed” which increases the amount of rotation of the operation handle 107 is not performed because the normal symbol operation gate 113b located at the upper right of the game area 106 passes, This is because it is difficult to win the first starting prize-winning device 112 located at the “nose”. In this state, the second start winning device 115 (hereinafter also referred to as electric Chu 115) is in the first mode in which a game ball cannot be won.

  When the game ball passes through the normal symbol operation gate 113a, the normal symbol display on the normal symbol display device 118 is started based on the passage, and a symbol matching game related to the lottery of the normal symbol is performed. When the game ball wins the first start winning device 112, the special symbol variation display is started on the first special symbol display device 120 based on the winning, and the image display is performed in synchronization with the special symbol variation display. A variation display of the effect symbol is started on the device 131, and a symbol matching game related to the special symbol jackpot drawing is performed.

  With reference to FIG. 2, here, various random numbers used in the gaming machine 100 of the present embodiment will be described. FIG. 2 is an explanatory diagram of a random number table from which various random numbers are acquired in the gaming machine 100 of the present embodiment, where (a) is a big hit random number table, (b) is a big hit symbol random number table, and (c) is a reach random number table. , (D) is a diagram showing an example of a winning random number table, and (e) is an example of a winning symbol random number table. The special symbol (effect symbol) is generated based on the jackpot random number acquired from the jackpot random number table shown in FIG. 2 (a) and the jackpot symbol random number acquired from the jackpot symbol random number table shown in FIG. 2 (b). In addition, the normal symbol is generated based on the hit random number obtained from the hit random number table shown in FIG. 2 (e) and the hit symbol random number obtained from the hit symbol random number table shown in FIG. 2 (e). .

  In the jackpot random number table shown in FIG. 2 (a), one random number value is acquired from 300 random numbers from "0" to "299", for example, when the first start winning device 112 and the electric chew 115 are won. The In the case of the jackpot random number table, in the low probability gaming state (the gaming state in which the jackpot probability is low), the jackpot ratio is set to 1/300, for example, and the acquired jackpot random number value is “3” A big hit is determined.

  On the other hand, in the high-probability gaming state (the gaming state in which the jackpot probability is high), the jackpot ratio is set to 10/300, which is 10 times the low-probability gaming state, and the acquired jackpot random number value is “3”, A big hit is determined when “7”, “37”, “67”, “97”, “127”, “157”, “187”, “217”, “247”.

  In addition, in the big hit random number table, a lottery for small hits is also performed. In the example shown in FIG. 2A, the ratio of small hits is set to 6/300, and the acquired big hit random numbers are “0”, “50”, “100”, “150”, “200”, “250”. "Is determined to be a small hit. When this small hit is made, the opening mode of the big winning device 117 operates in the same manner as the opening mode of the big winning device 117 for the probability variation 2R big hit described later.

  In the jackpot symbol random number table shown in FIG. 2B, one random number value is acquired from 250 random numbers from “0” to “249”. And based on the acquired jackpot symbol random number, any one jackpot is determined from a plurality of kinds of jackpots. In the gaming machine 100 of the present embodiment, three types of big hits are usually prepared as a plurality of types of big hits: 8R big hit (with time reduction), probability variation 16R big hit (with time reduction), and probability variation 2R big hit (no time reduction). There are four or more types of jackpots, such as those with different numbers of rounds and those with different opening / closing modes of the door 117b of the big winning device 117 (for example, different opening / closing times and prescribed winning numbers). May be.

  Normally, the number of rounds at the time of a big hit game is 8 rounds, and the open / close door 117b of the big prize device 117 in the round has a predetermined time (for example, 29.5 seconds) or a predetermined number of prizes (max 9). It is a big hit that is released until the ball wins, and the payout of the outgoing ball as a winning ball is not expected very much (eg 1000), but after the big hit game ends, the special symbol changes until a predetermined number of times (eg 100 times) It is a big hit that grants short duration games for a period.

  The probability variation 16R jackpot has 16 rounds at the time of the jackpot game, and the open / close door 117b of the big winning device 117 in the round is a game with a predetermined time (for example, 29.5 seconds) or a prescribed winning number (max 9). It is a big hit that is released until the ball wins, and you can expect payout of the outgoing ball as a prize ball (for example, 2000), and after the big hit game, both high probability games and short-time games until the next big hit It is a jackpot to grant.

  Probability 2R jackpot has a small number of rounds at the time of jackpot game as few as two rounds, and the opening time of the door 117b of the big winning device 117 in the round is extremely short (for example, 0.2 seconds, but the maximum number of winning prizes is 9) Although it is a big hit, it is almost a big hit that gives a high probability game until the next big hit after the big hit game is finished, though it is almost impossible to expect the payout of the ball as a winning ball (almost no winning).

  The opening mode of the big winning device 117 in the probability variation 2R big hit is the same operation as the small hit, and since the short-time game is not given after the big hit game is finished, the player apparently has the probability variation 2R big hit and the small hit. A distinction cannot be made. Therefore, after the jackpot game of the probability variation 2R jackpot, the player cannot recognize that the gaming state has a high probability internally, that is, the probability variation 2R jackpot corresponds to a so-called “latent probability variation jackpot”. .

  Further, in the gaming machine 100 of the present embodiment, the ratio at which the big hit is selected is different between when the game ball enters the first start winning device 112 and when the game ball enters the electric chew 115. It is configured. Specifically, as shown in FIG. 2 (b), if the big hit symbol random number obtained when the game ball wins the first start winning device 112 is “0” to “99”, the normal 8R big hit is selected. The ratio in this case is 100/250, and if it is “100” to “174”, the probability variation 16R big hit is selected, and the ratio in this case is 75/250, and if it is “175” to “249”, Probability 2R jackpot is selected, and the ratio in this case is 75/250.

  On the other hand, if the big hit symbol random number acquired when the game ball is won by the electric chew 115 is “0” to “99”, the 8R big hit is usually selected. In this case, the ratio is 100/250, and “100” to “100” 249 ”, the probability variation 16R big hit is selected, and the ratio in this case is 150/250. The probability variation 2R jackpot is not selected when winning the electric Chu 115.

  Comparing the type of jackpot selected at the time of winning the first start winning device 112 and the time of winning the electric Chu 115, the ratio of the probability variation 16R jackpot at the time of winning the first start winning device 112 is 75/250. When the electric Chu 115 wins, the ratio of the probability variation 16R big hit is 150/250, and when the electric Chu 115 wins, the ratio at which the probability variation 16R big hit is selected is higher. Furthermore, when the first start winning device 112 is won, the ratio of the probable 2R jackpot is 75/250, whereas when the electric Chu 115 prize is won, the ratio of the probable 2R jackpot is 0/250 (note that the first As shown in the pie chart of FIG. 5 (b), the distribution of the probability variation big hit (or the normal big hit) selected at the time of the one start winning device 112 and the electric Chu 115 prize is the same (the ratio of the probability variation big hit is 150/250, usually the ratio of big hits is 100/250)).

  That is, the electric chew 115 is configured to be more advantageous for the player than the first start winning device 112. With this configuration, when the game state shifts to the so-called electric-chu-support game state (short-time game state) in which the winning rate of the game ball to the electric chew 115 is high, the probability of consecutive winning of the probability variation 16R jackpot increases. Therefore, it can be expected that a large number of balls will be obtained, and a highly interesting game can be provided.

  In the reach random number table shown in FIG. 2 (c), when the game ball is won by the start winning device (the first start winning device 112 or the electric Chu 115), among 250 random numbers from “0” to “249”. One random value is acquired. In the case of the reach random number table, the reach ratio is set to 22/250, for example, and it is determined that the reach is present when the acquired reach random number value is “0” to “21”. On the other hand, the ratio of no reach is set to 228/250, and it is determined that there is no reach when the acquired reach random number values are “22” to “249”. The reach random number is a random number for determining whether or not a reach effect is performed when a special symbol lottery is lost.

  In the hit random number table for drawing the random numbers of normal symbols shown in FIG. 2D, when the game ball passes through the normal symbol operation gates 113a and 113b, the ten random numbers from “0” to “9” are selected. One random value is acquired. In the case of a winning random number table, in a gaming state other than a short working time (hereinafter also referred to as a short working time gaming state), the winning ratio is set to 1/10, for example, and the winning random number value is “7”. Determined. On the other hand, in the short-time gaming state, the winning ratio is set to 9/10 that is nine times that of the non-short-time gaming state, and it is determined that the winning number is “0” to “8”.

  In the hit design random number table shown in FIG. 2E, one random number value is acquired from three random numbers from “0” to “2”. Then, based on the acquired winning design random number, any one of a plurality of types of winning is determined. In the gaming machine 100 of the present embodiment, two types of hits, short and long, are prepared as a plurality of types.

  Short wins per short period (for example, a single open of 0.5 seconds, a maximum number of winnings of 9 max), which is controlled to the second mode in which the electric Chu 115 is opened when a win is won by a normal symbol lottery. On the other hand, the long win is per long time during which the electric chew 115 is controlled to the second mode (for example, a single opening of 6 seconds and a maximum number of winning prizes of 9). In the case of the winning symbol random number table, the ratio per short is set to 2/3, for example, and when the acquired winning symbol random number value is “0” or “1”, it is determined that the hit is short. The ratio is set to 1/3, for example, and when the acquired winning symbol random number value is “2”, it is determined to be long hit.

  In the short hit, since the time for which the electric Chu 115 is controlled to the second mode is short open, it is difficult to win a game ball to the electric Chu 115, and therefore it is almost possible to expect the payout of the outgoing ball as a prize ball. In addition, the special symbol jackpot lottery based on the winning is almost impossible to expect.

  On the other hand, in the long win, since the time for which the electric chew 115 is controlled in the second mode is long open, it is possible to expect a plurality of game balls (upper limit is 9) to win the electric chew 115. As a result, it is possible to expect a payout of a special ball as well as a special symbol jackpot lottery based on the winnings. In addition, as described above, the rate of selection of the probability variation 16R big hit is higher when the electric Chu 115 wins than when the first start winning device 112 wins. Winning the electric Chu 115 is an extremely important item in the game, and this improves the game preference.

  Note that this winning symbol random number table is used only for the short-time gaming state, and when the gaming state is short, when the normal symbol lottery is won, The time controlled in the mode of 2 and the release mode are all performed in accordance with the above long (for example, a single release of 5 seconds, a specified maximum number of winnings of 9).

  Returning to FIG. 1, when the player is “left-handed” in the normal gaming state, the symbol matching game related to the normal symbol lottery is started, and the normal symbol display device 118 changes the normal symbol. When the normal symbol stops and lights up or turns off after a predetermined fluctuation time has elapsed since the start of the blinking operation as a display, it is confirmed and displayed, and if this confirmed normal symbol is lit, it becomes a win (see FIG. 2 (d) When the winning random number value obtained in the winning random number table is “7”, the winning probability is 1/10), and the electric Chu 115 is controlled to the second mode (the movable piece 115b is in the open state) in which the winning chance of the game ball is increased. Is done.

  At this time, when the normal symbol hit is short hit (the ratio 2/3 when the hit symbol random number value obtained by the hit symbol random number table of FIG. Since the opening time is short (single opening of 0.5 seconds) and it is not easy to win this electric Chu 115, the player has left-handed as it is as shown by the arrow A in FIG. The state will be maintained. As a result, the game ball rarely wins the electric chew 115 if lucky.

  On the other hand, when the normal symbol hit is long hit (the rate is 1/3 when the hit symbol random number value obtained in the symbol random number table of FIG. Is long (single opening for 6 seconds), and when the electric chew 115 is in the open state, the player increases the amount of rotation of the operation handle 107 and performs “right-handed”.

  When the “right strike” is performed, the game ball falls on the right side of the image display device 131 in the game area 106 as shown by an arrow B in FIG. Then, the game ball that has reached the guide plate 116 is guided to roll on the guide plate 116 and win a prize to the open electric chew 115. Thereby, a large number of game balls easily win the electric chew 115.

  Then, when a game ball wins the electric chew 115, based on the winning, the special symbol variation display on the second special symbol display device 122 and the effect symbol variation display on the image display device 131 are started. A symbol matching game related to the lottery is performed. Note that when the electric chew 115 is in the open state due to a long hit, the game ball wins the electric chew 115 even if the player does not “right hit” and does “left hit” as it is. Although it is possible, the winning efficiency is lower than when the right board is used and the guide plate 116 is not used, which is disadvantageous for the player.

  Thus, when the game ball is won in the first start winning device 112 or the electric chew 115 and the symbol matching game related to the special symbol jackpot drawing is performed, the image display device 131 displays the first effect button 135 and the second Reach effect that makes the player operate the effect button 136 and operates the gimmick 109 in a predetermined manner on the front of the screen of the image display device 131 (the big hit acquired with the big hit random number table of FIG. 2A) When the random number value is “3”, the ratio is 1/300, or when the reach random number value acquired from the reach random number table of FIG. 2C is “0” to “21”, the ratio is 22/250. Therefore, the player pays more attention to the image display device 131 than to the first and second special symbol display devices 120 and 122.

  In addition, when a symbol matching game related to a lottery of normal symbols is performed, a variation of the normal symbols is performed in a part of the image display device 131 (for example, a lower part or a corner of the image display device 131) at a predetermined ratio by lottery or the like. During the display, a roaring effect relating to whether or not the lottery result of the variable display is a win is executed. Therefore, in this case, the player can display the image display device 131 rather than the normal symbol display device 118. Will come to watch.

  In addition, the first start winning device 112, the electric tuner during the variable display of the special symbol (the effect symbol in the image display device 131) in the first special symbol display device 120 or the second special symbol display device 122, or during the big hit or the small hit. When a game ball wins in 115, the right to win a big win is reserved and stored (maximum of 4), and the first and second special symbol hold indicators 123 and 124 light in a predetermined manner according to the number of reserved memories. To do.

  Similarly, when a game ball passes through the normal symbol operation gates 113a and 113b during normal symbol fluctuation display or when the electric chew 115 is opened, the right of the winning lottery is held and stored (up to four). The normal symbol hold indicator 119 lights up in a predetermined manner according to the number of reserved memories. Thus, the player can check how many jackpots and winning lottery rights are currently reserved. In the gaming machine 100 of the present embodiment, the reserved memory related to the special symbol is digested with priority over the electric chew 115. You may make it carry out in order.

  Then, in the normal gaming state, the special symbol is stopped and fixedly displayed after a predetermined fluctuation time has elapsed from the start of the special symbol variation display on the first and second special symbol display devices 120 and 122. Is a big hit if it matches a predetermined big hit symbol (for example, “7”) (when the big hit random number value obtained in the big hit random number table of FIG. 2A is “3”, the big hit probability is 1/300). Also, a specific effect symbol combination (for example, “777” or the like) is stopped and displayed on the image display device 131, and the player is informed of the big hit as a special symbol lottery result (however, the probability variation 2R big hit is excluded).

  Then, when the lottery result of the special symbol becomes a big hit in this way, the opening / closing door 117b of the big winning device 117 is controlled to open and close in a predetermined manner, so that the chances of winning the game balls are greatly increased, and the player can play a large number of game balls. You can play a jackpot game that can earn you and increase your possession. When the big hit game is started, the player turns the operation handle 107 greatly to perform “right-handed”, and the player wins the big winning device 117 with the open / close door 117b located at the lower right of the game area 106 opened. Aim and fire a game ball.

  Here, the big hit symbol random number value obtained from the big hit symbol random number table of FIG. 2 (b) is normally “0” to “99” for both the first start winning device 112 and the electric chew 115, and the ratio 100 / 250), an 8-round jackpot game is played, and after the 8-round jackpot game ends, the game state is shortened for a period until the special symbol changes 100 times.

  In addition, the big hit symbol random number value obtained from the big hit symbol random number table in FIG. 2B is “100” to “174”, the ratio 75/250, the ratio 75/250, the electric hit In the case of 115, in the case of “100” to “249”, the ratio 150/250), a 16-round jackpot game is played, and after the 16-round jackpot game is over, the game state has a high probability until the next jackpot (FIG. 2 ( The big hit random number values acquired in the big hit random number table of a) are “3”, “7”, “37”, “67”, “97”, “127”, “157”, “187”, “217”, “ 247 ", the jackpot probability is 10/300) and the time is short. That is, the big hit loops. The number of loops of the big hit may be unlimited, and if the big hit is repeated a predetermined number of times (for example, five times), the next big hit may be forced to become the normal big hit (so-called limiter function). ).

  On the other hand, the jackpot symbol random value obtained from the jackpot symbol random number table of FIG. 2 (b) based on the winning of the first start winning device 112 is “175” to “249”, the ratio 75/250 ), A specific effect symbol combination is also stopped and displayed on the image display device 131. In this case, the reach effect is not performed regardless of the reach random value, and the effect symbol combination is not a doublet or the like. For example, a casual combination of numbers such as “359” is stopped and displayed so that the player cannot intentionally determine that the special symbol lottery result has been a promising 2R big hit. Then, a two-round jackpot game is performed, and after the two-round jackpot game is over, a high probability is hidden until the game state becomes the next jackpot.

  As a result of the big hit lottery, the big hit random numbers obtained in the big hit random number table in FIG. 2A are “0”, “50”, “100”, “150”, “200”, “250”. In the case of a small hit probability 6/300), a specific combination of effect symbols is stopped and displayed on the image display device 131. In this case, as with the probability variation 2R big hit, a combination of casual numbers and the like is stopped and displayed. The player is intentionally prevented from determining that a special symbol lottery result has been won. In other words, this is to confuse the player with the small hit and the probable variation 2R big hit, and to hide the high probability after the probable change 2R big hit (恰 also impersonates the low probability gaming state).

  In this way, the probability variation 16R jackpot that can win more balls is selected when the electric Chu 115 winning is larger than the first start winning device 112 winning (the stop at the probability variation 16R jackpot symbol). Since the probability is high, the player can have great expectation for the symbol matching game related to the special symbol based on the time of winning the electric chew 115.

  During the big hit game, the lower display 170 displays an image of “BONUS”. In addition, during the big hit game, an image of “MUSCLE” is displayed on the open / close door 117b. During the big hit game, the player performs “right-handed” and the game ball rolls on the guide plate 116, so that the game ball moves up and down by the display on the lower display 170 and the display on the open / close door 117b. It will roll in the area between. Therefore, the display on the lower display 170 and the display on the open / close door 117b become conspicuous.

  When the game state is short, the special symbol and the normal symbol change time is shortened, and in the symbol matching game related to the normal symbol, which is mainly performed based on the passage of the normal symbol operation gate 113b, a high probability (When the hit random number value obtained from the hit random number table of FIG. 2D is “0” to “8”, the hit probability is 9/10), and the electric Chu 115 is controlled to the second mode. Since the playing time and release mode are performed in accordance with the above long game, the chances of winning the game ball increase, and the player can maintain the current ball without reducing it.

  Therefore, when the short-time game is started, as in the case of the big hit game described above, the player operates the normal symbol located at the upper right of the game area 106 in order to perform the “right stroke” by rotating the operation handle 107 greatly. A game ball is launched aiming at the gate 113b. Regardless of whether or not the normal symbol operation gate 113b passes, the “right-handed” game ball finally reaches the guide plate 116, and the game ball that has reached the guide plate 116 rolls on the guide plate 116. Thus, it is guided to win a prize to the electric Chu 115 that is frequently opened. That is, in the short-time game, the player frequently wins the electric Chu 115 which is more advantageous to the player than the first start winning device 112. In the short-time game after the probability variation 16R jackpot game ends, the jackpot probability is even higher, so the game state is extremely advantageous for the player.

  During the time-saving game, an image of “RUSH” is displayed on the lower display 170. In addition, during the time-saving game, an image of “justice superman” is displayed on the open / close door 117b. During the short-time game, the player performs “right-handed” and the game ball rolls on the guide plate 116, so that the game ball moves up and down by the display on the lower display 170 and the display on the open / close door 117b. It will roll in the area between. Therefore, the display on the lower display 170 and the display on the open / close door 117b become conspicuous.

  In the short-time game, even if the player performs “left-handed”, the game ball can pass through the normal symbol operating gate 113a and can win the electric chew 115, but “right-handed” As compared with the case where the guide plate 116 is not used, the winning efficiency for the electric chew 115 is worse, and it becomes easier to win the first start winning device 112 which is disadvantageous for the player than the electric chew 115. It is disadvantageous for the player. The above is the main flow of the game in the gaming machine 100 of the present embodiment.
