Description

  According to the present invention, a lottery is executed under a predetermined lottery probability by winning a game ball in a start winning slot on the game board surface, and a plurality of types are selected under a predetermined selection probability based on an expected value of winning. The present invention relates to a gaming machine including a symbol variation pattern effect display device that executes a notification effect of the lottery result based on a symbol variation pattern selected from symbol variation patterns.

  Note that the expected value is the ratio at which the result of the production form for the production form to determine whether it is a win or a loss can be won, and more specifically, when each reach pattern is displayed, the result Indicates the rate at which the hit operation is performed.

  Conventionally, in a gaming machine, particularly a pachinko machine, in a normal gaming state, a lottery is made by detecting a pachinko ball won at a starting opening (special symbol starting winning opening), and if the result of the lottery is a win, A player who increases the winning rate of a game ball by opening a large number of winning holes, which are closed in a gaming state, for a predetermined period of time, a predetermined number of times (one opening and closing is one round and generally continues for 10 to 16 rounds). There is a pachinko machine having a special gaming state (hereinafter referred to as a big hit process) that is advantageous to the player.

  In this type of pachinko machine, a display unit such as a liquid crystal display device is arranged on a game board surface (generally, a center role etc. in the center), and a plurality of symbol rows are scrolled and changed on the display unit. The result of the lottery is notified in the symbol state (symbol arrangement state) of each column when stopped (hereinafter referred to as symbol variation pattern effect).

  There are multiple types of this symbol variation pattern based on the expected value of winning, and when the expected value is high, the other symbols that stop are the winning symbols before the final stop symbol stops. There is a reach pattern. For example, in a symbol variation pattern of three columns, a case where two rows that stop first become the same symbol when the same symbol is matched when three columns are aligned.

  Such a reach pattern gives the player a sense of expectation of winning, so it can be said that the expectation value is high.

  Even if such reach patterns are mixed, it is possible to improve the game preference.

By the way, among the above reach patterns, reach patterns having different expected values are set (for example, a normal reach pattern, a super reach pattern, a special (premium) reach pattern, etc. in descending order of expected values), and these are selected with a predetermined probability. If so, there is a high possibility that only the reach pattern having the highest appearance probability (generally, the normal reach pattern) is selected, and the player's expectation tends to be reduced. The appearance probability and the expected value are inversely proportional, and the expected value decreases as the appearance probability increases. Further, the appearance probability is a probability that a change pattern is selected after starting a prize.
Therefore, it has been proposed that when only a specific reach pattern is selected, the selection probability of the type of reach pattern is changed on the condition of time (see Patent Document 1).

According to this, it is not biased toward a specific reach pattern, and the expectation given to the player is not impaired.
JP 2003-175196 A

  However, in the conventional technique such as Patent Document 1, it is the minimum condition that the reach pattern is selected, and if the reach pattern itself is not selected, the game becomes short and the player's expectation is lost. It is. In other words, falling into a so-called “hamari” state can result in a significant reduction in game preferences.

  In consideration of the above-mentioned fact, the present invention provides a symbol variation pattern having an expected value that is greater than or equal to a predetermined value under a specific gaming state without significantly changing the total selection probability of the symbol variation pattern having an expected value that is greater than or equal to a predetermined value. It is an object to obtain a gaming machine that can be easily selected and can enhance the taste of the game.

The present invention is a ratio in which a lottery is executed when a game ball wins a start winning opening on the game board surface, and a result of the effect form that is a win or a lose result is determined. A gaming machine having a symbol variation pattern effect display device that executes a notification effect of the lottery result based on a symbol variation pattern selected from a plurality of types of symbol variation patterns based on an expected value, and having a preset probability A normal probability selection mode for selecting a symbol variation pattern below, a high probability selection mode for increasing the selection probability of reach pattern production in which symbols other than the final stop symbol among the plurality of variation symbol sequences become the symbol array at the time of winning , and a mode storage means for storing the low probability selection mode, to lower the probability of choosing the reach pattern effect, the re-in game a predetermined number in the normal probability selection mode The high shifts to the probability selection mode when Chipatan effect is not selected, the process proceeds to the low probability selection mode when the reach pattern effect in any of the normal selection probability mode or high-probability selection mode is executed Mode transition control means for transitioning to the normal probability selection mode after completion of a predetermined number of games set less than the predetermined number in the low probability selection mode, and the mode transition control means includes the low probability In the selection mode, when the reach pattern effect is executed, the low probability selection mode is continued, and in the high probability selection mode, the high probability selection mode is continued until the reach pattern effect is executed. And the normal probability selection mode corresponding to the execution rate of the advance notice effect in which the character appears. Previously set as a reference, based on the execution rate, performs the high probability the pre announcement lower the execution rate of the effect control during the transition to the selected mode, the pre announcement attraction the during the transition to the low probability selection mode of performs a control to increase the execution rate, the normal along with releasing the control execution rate system of the pre-announcement attraction at the time of transition to the probability selection mode, relative to the normal game state in which the lottery under the predetermined probability, As a privilege when a predetermined condition is satisfied, at least one of a high-probability gaming state in which the probability of the lottery increases or a short-time gaming state in which the chance of lottery per unit time is increased by reducing the symbol variation pattern performance time A game state changing means for shifting the game state to the normal probability selection mode based on each of the game states changed by the game state changing means. And the predetermined number of games executed in the low probability selection mode are respectively set .

According to the first aspect of the present invention, as a mode for selecting a symbol variation pattern having an expected value equal to or greater than a predetermined value, the mode storage means includes three types of modes: normal probability selection mode, high probability selection mode, and low probability selection mode. Remember the mode.

  In the normal gaming state, the symbol variation pattern is selected based on the normal probability selection mode. Here, in the mode transition control means, the high probability selection mode when the symbol variation pattern effect having the expected value greater than or equal to the predetermined value is not selected in the predetermined number of games (number of symbol variation execution times) in the normal probability selection mode. To move to. This makes it easier to select a pattern variation pattern having an expected value that is greater than or equal to a predetermined value.

  The mode shift control means shifts to the low probability selection mode when a symbol variation pattern effect having an expected value equal to or greater than the predetermined value is executed in either the normal selection probability mode or the high probability selection mode. Thereby, the balance with the high probability selection mode can be achieved, and the selection of the symbol variation pattern with the expected value exceeding the predetermined value in the low probability selection mode can further give the player a sense of expectation. .

  Note that after the predetermined number of games in the low probability selection mode, the normal probability selection mode is entered.

In this way, by changing the selection probability of the symbol variation pattern having an expected value greater than or equal to a predetermined value when selecting the symbol variation pattern, a so-called “hamari” (a period in which a symbol variation pattern effect having an expected value greater than or equal to the predetermined value is not selected) is selected. It is possible to promote the recovery of the willingness to play for a player who has entered a long game state. In addition, a balance of statistics (probability) in a relatively long span can be realized in a relatively short span.
In addition, if the selection probability is changed, there is a possibility that an effect that gives the player more expectation than necessary is increased due to the influence (a prior notice effect such as the appearance of a character). It is preferable to correct such a sense of expectation more than necessary. In that case, the mode may be grasped and controlled by the mode transition control means .

Lee Chipatan, because other than the final stop symbol is a symbol sequence at the time of winning, to expect the stop state of the final stop symbols, changing the selection probability of such a reach pattern, player's expectation Has a great influence. In addition, you may change not only a mere reach pattern (normal reach) but the pattern in which a notice effect produces simultaneously.

As the gaming state, there are a normal gaming state, a high-probability gaming state with a high probability of lottery, and a short-time gaming state in which the symbol variation pattern effect is shortened, and may be executed after jackpot processing as a privilege to the player.

  By setting the predetermined number of times to be executed in the normal probability selection mode and the predetermined number of games to be executed in the low probability selection mode based on each of the gaming states changed by the gaming state changing means, , You can balance in each gaming state.

  As described above, according to the present invention, a symbol variation pattern having an expected value greater than or equal to a predetermined value is selected under a specific gaming state without significantly changing the total selection probability of the symbol variation pattern having an expected value or greater than a predetermined value. It has the outstanding effect that it is easy to do and can improve the taste of a game.

  FIG. 1 shows a pachinko machine 10 according to the present embodiment. The pachinko machine 10 includes an outer frame 12, and one side portion (left side portion in FIG. 1) of a frame-shaped inner frame 14 having a window portion is attached to the front surface of the outer frame 12 so as to be openable and closable.

  The inner frame 14 is provided with a plurality of indicator lights 62 and speakers 64. In addition, a window portion is formed at the center of the inner frame 14, and a glass frame in which a pair of glasses 16 (double structure) that are parallel to each other at a predetermined interval in the depth direction of the paper is mounted on the window portion. 20 is provided. A locking device (cylinder) 22 is provided on the right side of FIG.

  An integrated dish 26 having a ball dish part 24 is disposed below the glass frame 20. The ball tray portion 24 of the integrated dish is provided with a communication port 23 that communicates with a ball storage tank (not shown) and allows the pachinko balls in the ball storage tank to flow out to the ball tray portion 24.

  The one side part (left side part of FIG. 1) of the integrated dish 26 is attached to the inner frame 14 so that it can be opened and closed. An ashtray 28 is disposed at the lower left side on the front surface of the integrated dish 26, and a firing handle 30 is provided at the lower right side for adjusting the flight distance of the hit ball launched from the launching device 164 (see FIG. 3).

  In addition, a game board 32 that is exchangeable by being placed on the game board mounting table is installed in the window part of the inner frame 14 so as to correspond to the window part.

  As shown in FIG. 2, the game board 32 has a substantially circular game area 40 surrounded by an outer band 36 and an inner band 38.

  In the game area 40, in addition to nails and windmills (not shown), a center character 42, a display unit 43 provided in the center character 42, and a character such as a big prize port (variable prize device) 44, a start port 46 Game parts such as a passing device 48 and a winning device 49 are attached, and an out port 54 is arranged at the lowest position. A normal symbol display device 42A is provided at the upper end of the center accessory 42.

  The passing device 48 serves as a start trigger for the normal symbol display device 42A. When the pachinko ball passes through the passing device 48, the normal symbol lottery is executed. In the case of winning, the display of the normal symbol display device 42A displays the winning symbol. Then, the electric tulip 47 is opened, and the probability of winning the winning opening 46 is physically increased.

  In addition, a holding lamp 100 is provided at the top of the display unit 43. In the present embodiment, a maximum of four holding lamps can be held, and therefore four holding lamps 100 corresponding to this number are provided. ing.

  “Hold” means waiting for notification of the result of the lottery executed by the winning when the display unit 43 newly wins the start opening 46 while executing the symbol variation pattern effect. In addition, even when winning at the start port 46 during the jackpot process, the display unit 43 reproduces the video pattern of the jackpot process effect, so that the game is put on hold. However, there is a limit to the number of suspension (four in the present embodiment), and winnings to the starting port 46 beyond this are not subject to lottery.

  FIG. 3 shows an outline of a control system for controlling the pachinko machine 10. The control system is configured around the main control unit 150. The main control unit 150 stores a basic program relating to games, and the operation of each unit is controlled based on a command signal from the main control unit 150.

  The main control unit 150 includes a start winning sensor 168 provided in the starting opening 46, a passing / winning sensor 172 provided in the passing device 48 and the winning device 49, and a large pachinko ball that has won a prize winning port 44. A prize opening sensor 173 is connected. The special winning opening 44 is provided with a V zone for continuing the opening / closing operation of the special winning opening, and a V zone sensor 177 is also provided in this V zone and is connected to the main control unit 150. ing. Note that the V zone sensor 177 may be omitted and only the special winning prize sensor 173 may be used.

  Furthermore, a solenoid 174 for opening and closing an electric tulip 47 (see FIG. 2) provided at the start winning opening 46 and a solenoid 175 for opening and closing the large winning opening 44 are connected to the main control unit 150.

  The main controller 150 outputs information indicating the progress of the game to the hall computer via the board external terminal 200.

  Here, when the pachinko ball wins the start opening 46, the lottery is executed by detecting this with the start winning sensor 168. In the case of winning, the game state is changed from the normal game state to the special game state. Are to be migrated.

  On the other hand, an effect control unit 152 and a payout control unit 154 are connected to the main control unit 150.

  The effect control unit 152 is connected to the speaker 64, the display unit (LCD) 43 of the center accessory 42, the normal symbol display device 42 </ b> A, and the hold lamp 100 via the symbol / sound controller 156. In addition, the effect control unit 152 controls turning on / off of the plurality of indicator lights 62 attached to the glass frame 20 of the pachinko machine 10. The display unit 43 displays a symbol variation pattern effect image for notifying the lottery result, and the speaker 64 outputs BGM at the time of the symbol variation pattern effect. That is, the player can enjoy the production including the result of the lottery through visual and auditory senses. Note that the normal symbol display device 42 </ b> A and the hold lamp 100 may be displayed on the display unit 43.

  Next, a payout device 206 for paying out pachinko balls is connected to the payout control unit 154 connected to the main control unit 150.

  In addition, a launch control unit 158 is connected to the payout control unit 154, and the launch control unit 158 controls the launch device 164 to launch a pachinko ball according to the operation of the handle 30 by the player.

  Furthermore, the payout control unit 154 sends payout information to the hall computer installed in the hall via the frame external terminal 208.

  Here, when the result of the lottery is a win and the winning of the symbol variation pattern effect on the display unit 43 and the BGM output from the speaker 64 is informed, the jackpot process which is a special gaming state is executed.

  In the jackpot process, the big winning opening 44 is opened a predetermined number of times (round). The opening time of one round is 30 seconds, and a maximum of 10 pachinko balls can be won during this period. That is, when either the time limit of 30 seconds or the number limit of 10 is satisfied first, the right of the round is extinguished, and during the jackpot processing, to the V zone in the big winning opening 44 If there is a win, it is promised to move to the next round. It is also possible to omit the V zone, simply count a predetermined number, and continue based on that.

  For this reason, in the special gaming state, more winnings are expected in a shorter period than in the normal gaming state, and a gaming state advantageous to the player can be achieved.

  As described above, when the display unit 43 newly wins the start opening 46 during the execution of the symbol variation pattern effect, and when the winning opening 46 is won during the jackpot process, the display of the hold lamp 100 is correspondingly displayed. The number of lights increases (maximum 4).

  On the other hand, when the previous symbol variation pattern effect ends or the jackpot process ends, the display unit 43 starts a new symbol variation pattern effect to notify the lottery result for the hold. Along with this, one hold lamp 100 is extinguished and the player is informed of the digestion of the hold.

  By the way, the above-described symbol variation pattern is determined by symbol variation pattern selection lottery after winning / losing lottery.

  In other words, there are multiple types of symbol variation patterns, and among them, there are various types from low to high in the expected value of winning, and it is displayed separately from the lottery result notification that is the original purpose for the player. It is possible to provide the taste by the production in the section 43.

  There is a reach pattern as a boundary (equivalent to the threshold value shown in claim 1) where the expected value is most clearly increased. The reach pattern is a state in which, among the three rows of symbol variations, the two rows of symbols that stop first stop at the winning symbol (the same symbol), and the symbols in the last column vary.

  When this reach pattern is reached, the expected value of the winning will increase dramatically, and the player will see the symbol variation pattern effect on the display unit 43 with a sense of expectation.

  Here, even in the state where the same deviation continues, the reach pattern may not be selected at all (so-called “hamari” state). Under such circumstances, the player's willingness to play declines, leading to a reduction in the operating rate due to the stand apart. In addition, as long as the winning probability is determined, a long span (1 day, 1 week, etc.) results in accordance with this winning probability, so this is not a problem in gaming specifications, but a short span (one player is In a few hours of playing), the result does not correspond to the winning probability, and often falls into the “hamari” state as described above.

  Therefore, in this embodiment, the selection probability of the pattern variation pattern is added to the normal probability selection mode, the high probability selection mode and the low probability selection mode are set, and the mode is changed when a predetermined condition is satisfied. In addition, it has been possible to eliminate the “Humari” state in a short span.

  FIG. 4 shows a functional block diagram for mode setting control in the main control unit 150.

  The start winning sensor 168 is connected to the lottery unit 250. When the start winning sensor 168 detects the winning of the pachinko ball start port 46, the lottery is executed on condition that the winning is effective for the lottery.

  The lottery result of the lottery unit 250 is sent to the winning / excluding determination unit 252 to determine whether the lottery result is a hit or miss.

  This determination result is sent to the gaming state control unit 254, so that the subsequent gaming state is controlled. In the gaming state control unit 254, when it is necessary to control the effect control unit 152 according to the gaming state, the command generation unit 256 is controlled when necessary, and a command is generated. The command output unit 258 causes the effect control unit 152 to Command is sent.

  The winning / excluding determination unit 252 is connected to the symbol variation pattern selecting unit 260, and the symbol variation pattern is selected based on the determination result.

  The selection of the symbol variation pattern in the symbol variation pattern selection unit 260 is executed based on the set selection probability mode.

  This selection probability mode is set by the selection probability setting unit 262 and outputs a mode determination signal to instruct the symbol variation pattern selection unit 260 to select a variation pattern from the selected mode.

  A selection probability mode memory 264 is connected to the selection probability setting unit 262.

  The selection probability mode memory 264 stores three types of modes: a normal probability selection mode, a high probability selection mode, and a low probability selection mode. The modes may be stored in the high probability gaming state, the short-time gaming state, and the normal gaming state, respectively.

  The selection probability setting unit 262 selects and reads out one of the three types of modes based on a predetermined condition (described below), and sends it to the symbol variation pattern selection unit 260.

  The selection probability setting unit 262 is connected to the mode recognition unit 266. When the mode is changed based on the recognized mode, the mode recognition unit 266 changes the selection probability setting unit 262 to the symbol variation pattern selection unit. In response to an instruction to 260, an activation signal (reset / start instruction signal) is sent to the normal probability counter activation unit 268 or the low probability counter activation unit 270 at the same timing.

  Further, a mode change command generator 267 is connected to the mode recognizer 266, and a command to be sent to the effect controller 152 is generated every time the mode is changed, and is output by the command output unit 258. Yes. This output is controlled to have priority over the variation pattern designation command.

  This mode change command functions as one of determinations for determining whether or not a character or the like appears in the same symbol variation pattern in the effect control unit 152. That is, when the reach pattern is frequently selected in the high probability selection mode, the appearance of characters increases, and on the contrary, the control is executed to reduce the appearance rate of characters and the like to avoid giving the player a sense of incongruity. Is done. For example, the effect control unit 152 may also include a mode recognition unit to control the advance notice effect control in accordance with the mode based on reception of the mode change command.

  The normal probability counter activation unit 268 is connected to the normal probability counter 272. When the normal probability selection mode is set, an activation signal is sent to the normal probability counter activation unit 268, and the reset / start of the normal probability counter 272 is controlled.

  In the present embodiment, the normal probability counter 272 is based on the countdown signal from the symbol variation pattern type determination unit 276, for 50 games (opportunity to win the starting port 46 effective for lottery (number of symbol variation executions)). Is counted (counted down) and counted up (becomes 0), it is sent to the selection probability setting unit 262 for instructing the transition from the normal probability selection mode to the high probability selection mode.

  The low probability counter activation unit 270 is connected to the low probability counter 274. When the low probability selection mode is set, the low probability counter activation unit 270 is transmitted with an activation signal, and controls reset / start of the low probability counter 274.

  In the present embodiment, the low-probability counter 274 is based on a countdown signal from a symbol variation pattern type determination unit 276, which will be described later. Count)) (countdown), and count up (becomes 0), it is sent to the selection probability setting unit 262 instructing the transition from the low probability selection mode to the normal probability selection mode (outputs a mode promotion signal) ).

  On the other hand, the result selected by the symbol variation pattern selection unit 260 is sent to the symbol variation pattern type determination unit 276.

  The symbol variation pattern type selection unit 276 determines whether or not the selected symbol variation pattern is a reach pattern, and sends the determined symbol variation pattern type to the command generation unit 256. In the command generation unit 256, a symbol variation pattern designation command is generated based on the determined symbol variation pattern type, and is transmitted from the command output unit 258 to the effect control unit 152.

  The symbol variation pattern type determination unit 276 is connected to the normal probability counter 272, the low probability counter 274, and the reset unit 278. The countdown signal is sent to the normal probability counter 272 and the low probability counter 274 as described above. In addition, a reach signal is input to the reset unit 278 when a reach pattern is selected by the symbol variation pattern type determination unit 276, and based on the input of the reach signal, regardless of the current probability selection mode, The selection probability setting unit 262 is instructed to shift to the low probability selection mode (a mode demotion signal is output).

That is, in the selection probability setting unit 262, the following mode change setting is executed.
(1) In the normal probability selection mode, if the reach pattern is not selected in 50 symbol variation pattern selection opportunities, the mode shifts to the high probability selection mode.
(2) When the reach pattern is selected in the normal probability selection mode or the high probability selection mode, the mode shifts to the low probability selection mode.
(3) In the low probability selection mode, when the three symbol variation pattern selection opportunities are completed, the mode shifts to the normal probability selection mode.
(4) When the reach pattern is selected in the low probability selection mode, the low probability counter is reset and started, and the low probability selection mode is continued.

  Here, an example of the probabilities of the above three types of modes in the normal gaming state is shown.

The “total reach pattern selection probability” in Table 1 above indicates the probability that a reach pattern is selected including the winning reach, and the jackpot probability is calculated as 1/320. That is, the jackpot is 1/320 because all the reach patterns are reach patterns. The “outgoing reach pattern selection probability” in Table 1 above is the probability of outliers (319/320), which is (23/251) × (319/320). This result and the jackpot reach The sum of the pattern probability (1/320) is the “total reach pattern selection probability”. Therefore, the total reach pattern selection probability in the normal probability selection mode is
(23/251) x (319/320) + (1/320) ≒ 0.0941 (1)
It becomes.

Similarly, the total reach pattern selection probability in the low probability selection mode is
(4/251) x (319/320) + (1/320) ≒ 0.0191 ... (2)
It becomes.
In addition, the total reach pattern selection probability in the high probability selection mode is
(60/251) x (319/320) + (1/320) ≒ 0.242 ... (3)
It becomes.

  The operation of this embodiment will be described below.

  First, the flow of normal games will be described.

  When the player holds the handle 30 and performs an operation for launching, a pachinko ball is launched with a strength corresponding to the handle operation amount (rotation amount).

  When the pachinko ball is launched, it is guided by the outer band 36 and the inner band 38 and abuts against a nail, a windmill or the like of the board surface 32 and falls while moving unpredictably. Here, when a pachinko ball wins at the start port 46, the lottery unit 250 equipped with a random number counter or the like starts lottery with a predetermined probability.

  When the lottery result is a win, execution of the jackpot process is started, and a jackpot process with a preset number of rounds (for example, 15 rounds) is executed. During the jackpot process, since the big prize opening 44 is almost open, it can be put in an advantageous state by the player. When the jackpot processing for a predetermined round is completed, the game returns to the normal game.

  By the way, among the symbol variation patterns, when the reach pattern is reached, the expected value of the winning is dramatically increased, and the player sees the symbol variation pattern effect on the display unit 43 with a sense of expectation. When no reach pattern is selected (so-called “hamari” state), the player's willingness to play is reduced. Therefore, in the present embodiment, when a predetermined condition is satisfied in the selection probability mode of the symbol variation pattern, the mode change is executed, and the elimination of the “humidity” state in a short span is realized.

  The symbol variation pattern selection probability mode setting control routine will be described below with reference to the flowchart of FIG. This routine is processed when there is a pachinko ball winning that is effective for the lottery at the starting port 46 (that is, winning within the limit of holding).

  In step 300, as an initial setting (when the power is turned on), a low probability counter (reach counter) 274 and a normal probability counter (reach-hull counter) 272 are reset and started, and then the process proceeds to step 302.

(Normal probability selection mode → High probability selection mode)
First, when the game proceeds in the normal probability selection mode and the reach pattern is not selected in 50 symbol variations, in step 302, whether or not the reach pattern is selected in the symbol variation pattern selection unit 26. Is judged. A negative determination is made in step 302, and the process proceeds to step 304 to determine whether or not the mode being executed selected by the selection probability setting unit 262 is the low probability selection mode.

  In the above case, since a negative determination is made in step 304, the process proceeds to step 306, where it is determined whether or not the normal probability counter (reach humor counter) 272 has become 0 (count up).

  If the symbol variation pattern selection in the normal probability selection mode does not reach 50 times, a negative determination is made in this step 306, the process proceeds to step 308, and the normal probability counter (reach humor counter) 272 is decremented by “1”. The process proceeds to step 310, and it is determined again whether or not the normal probability counter (reach humor counter) 272 has become 0 (counted up).

  If a negative determination is made in step 310, the process returns to step 302. Further, in step 310, an affirmative determination is made, that is, it is determined that the normal probability counter (reach humor counter) 272 has become 0 (counted up) (no reach pattern is determined, and 50 symbol variation patterns have been selected). ), The process proceeds to step 312.

  In step 312, the high probability selection mode is set by the selection probability setting unit 262, and then the process proceeds to step 314 where the high probability selection mode command is passed through the mode recognition unit 266, the mode change command generation unit 267, and the command output unit 258. It transmits to the production control unit 152. With this transmission, for example, the effect control unit 152 changes the prior notice effect control according to the mode in the mode recognition unit on the effect control unit 152 side, and sets the probability of the effect to increase the expected value such as the appearance of the character. Controlled to lower.

  When the mode is shifted to the high probability selection mode, Steps 302, 304, and 306 are repeated until an affirmative determination is made in Step 302, that is, a reach pattern is selected by the symbol variation pattern selection unit 260. In other words, the high probability selection mode is continued until a reach pattern is selected.

  If an affirmative determination is made in step 302 (reach pattern selection by the symbol variation pattern type determination unit 276), the process proceeds to step 316. In the normal probability selection mode, the process proceeds from step 302 to step 316 also when a reach pattern is selected on the way.

(Normal probability selection mode or high probability selection mode → low probability selection mode)
In step 316, the low probability counter (reach counter) 274 is reset and started, and then the process proceeds to step 318 where the selection probability setting unit 262 sets the low probability selection mode. In the next step 320, the command (low probability selection mode command) generated by the mode change command generation unit 267 based on the mode (low probability selection command) recognized by the mode recognition unit 266 is sent from the command output unit 258 to the effect control unit. Transmit to 152 and return to step 302. By this transmission, the effect control unit 152 is controlled to increase the probability of an effect that frequently increases an expected value such as the appearance of a character, contrary to the restriction when the mode is shifted to the high probability selection mode.

(Low probability selection mode → Normal probability selection mode)
In the state set in the low probability selection mode, it is determined in step 302 whether or not reach is reached. In this low probability selection mode, the probability that a reach pattern is selected is extremely low. Conversely, when a reach pattern is selected, it can be said that the expected value per hit is dramatically high. For this reason, if the player recognizes that the current mode is the low-probability selection mode, the player will look at the pattern variation pattern with a great sense of expectation. The recognition may be positively notified that the mode is the low probability mode, or may be recognition by collecting information from a player's magazine, the Internet, or the like.

  If the reach pattern is selected and the result of the lottery is off, the process proceeds to step 316, and the low probability counter (reach counter) 274 is reset and started.

  On the other hand, if a negative determination is made in step 302, it is determined in step 304 whether or not the mode recognition unit 266 is in the low probability mode. In this case, an affirmative determination is made and the process proceeds to step 322.

  In step 322, "1" is subtracted from the low probability counter (Leachiagari counter) 274, and then in Step 324, it is determined whether or not the low probability counter (Leachiagari counter) 274 has become 0 (counted up). If the determination is negative, the process returns to step 302.

  If an affirmative determination is made in step 324, it is determined that the three low-probability selection modes have ended, the process proceeds to step 326, and the normal probability counter (reach humor counter) 272 is reset / started, and then step 328 is performed. To set the normal probability selection mode.

  In the next step 330, the normal probability selection mode command is transmitted to the effect control unit 152, and the process returns to step 302. With this transmission, the effect control unit 152 is controlled to cancel the control (control for increasing the probability of the effect that frequently increases an expected value such as the appearance of a character) when the mode is shifted to the low probability selection mode.

  As described above, in the present embodiment, the selection probability setting unit 262 prepares three types of modes, and in the normal probability selection mode, when a reach pattern is not selected at 50 symbol variation pattern selection opportunities, When the reach pattern is selected in the normal probability selection mode or the high probability selection mode, the mode is shifted to the low probability selection mode. In the low probability selection mode, there are three symbol variation pattern selection opportunities. When finished, the mode is shifted to the normal probability selection mode.When the reach pattern is selected in the low probability selection mode, the low probability counter is reset and started, and the low probability selection mode is continued. The state can be avoided, the game preference is increased, and the operation rate can be increased. After hitting, since a hit reach pattern is passed, the low probability selection mode is started. However, after hitting, it may be controlled to start from the normal state.

  In the present embodiment, the gaming state has been described as the normal gaming state. However, as a big bonus, a short-time (time reduction) gaming state and a probabilistic (probability variation) gaming state are generally made. In such a gaming state, it is preferable to set a symbol variation pattern selection probability and a mode change condition. For example, the normal state control unit 254 in the main control unit 150 detects the short-time gaming state and the probability variation gaming state, and outputs a threshold change signal to the threshold memory according to the state, and sets the setting based on the threshold change signal. You just have to do it.

  Table 2 shows the symbol variation pattern selection probability in the short-time gaming state.

  Also, in this short game state, the count-up value of the normal probability counter 272 (reach-hatch counter) is 80, and the count-up value of the low-probability counter 274 (reach counter) is 3.

  Table 3 shows the symbol variation pattern selection probability in the probability variation gaming state.

  Further, in this probability variation gaming state, the count-up value of the normal probability counter 272 (reach-hatch counter) is 70, and the count-up value of the low-probability counter 274 (reach counter) is 3.

  The above numerical values are not intended to limit the present invention, and the numerical values are particularly limited as long as the probability is balanced with normal probability, low probability, and high probability (low probability value <normal probability value <high probability value). Is not to be done.

  Furthermore, it may be so controlled that the state of each mode is notified to the player by the display unit 43 or the like. For example, changing the color of the hold lamp 100, changing the screen state of the display unit 43, and the like can be considered.
