Description

  The present invention relates to a gaming machine capable of shifting to a special gaming state in which a large number of prize balls can be obtained in a shorter period than the normal gaming state when a special symbol lottery is won in the normal gaming state. Is.

  Conventionally, in game machines, particularly pachinko machines, a lottery (special symbol lottery) has been made by detecting a pachinko ball that has won a special symbol start winning opening provided on the game board surface, and if this special symbol lottery is won, And a state that is advantageous to the player, which increases the winning rate of the game ball, and is opened a predetermined number of times for a predetermined period (one opening and closing is one round and generally continues for 10 to 16 rounds). There is a pachinko machine that is in a special gaming state (big hit processing).

  In this type of pachinko machine, a display unit (usually a liquid crystal display screen) is installed at the center of the gauge board of the pachinko machine as an effect of notifying the player of the result of the special symbol lottery. This display unit is configured with a plurality of columns (for example, three columns) of symbol variation pattern screens (there is also a background screen), and notifies the presence / absence of the symbol arrangement when stopped after the varying symbol variation pattern presentation. It is like that.

  By seeing the symbol variation screen, the player is amazed whether it is a hit or miss, so that the player can have a sense of expectation.

  An electric tulip is disposed in the winning opening of the special symbol starting winning opening.

  The trigger for opening and closing the electric tulip is a prize at a normal symbol start winning opening (also having a passage gate-like structure) provided on the surface of the game board. That is, a lottery (ordinary symbol lottery) is made by detecting a pachinko ball that has won the normal symbol start winning opening, and when the normal symbol lottery is won, the electric tulip is released a predetermined number of times for a predetermined period, and the special symbol start It is possible to increase the winning rate to the winning opening.

  By the way, in recent years, by winning the special symbol lottery, a privilege lottery right for obtaining a privilege can be obtained. The bonus lottery is determined by the type of the special symbol won by the special symbol lottery. However, the bonus lottery is referred to as “re-lottery” in the game, and the bonus lottery is separately performed.

  Benefits include probability variation of special symbol lottery (hereinafter referred to as “special symbol probability variation”), time variation of symbol variation pattern (hereinafter referred to as special symbol time reduction), and probability variation of normal symbol (hereinafter referred to as “special symbol time variation”). In general, a combination with at least one of the time shortening of the normal symbol variation pattern (hereinafter referred to as “short for normal time”) is generally used.

  Furthermore, in recent years, even if a lottery is made in the privilege lottery (re-lottery), a privilege different from the privilege at the time of winning is also given.

  For example, it has been proposed to give a special figure certain change as a privilege when winning a special symbol and winning a re-lottery, and to give a special time reduction as a privilege when winning a re-lottery (patent Reference 1).

In Patent Document 1, it is said that the game state can be variously changed and the expectation can be increased step by step by adopting the above-described technique in the game.
JP 2004-41263 A

  However, in the above-mentioned Patent Document 1, after the special gaming state (big hit process) is finished, the degree of advantage to the player when the special figure is changed and the advantage to the player when the normal drawing time is shortened The parameter for comparing the degree is ambiguous. Therefore, as a demerit to give a privilege, it is a parameter that is a parameter indicating the profit / loss of the store side (the ratio of the total number of payouts / number of shots. The number of payouts is not included. On the other hand, even when trying to restore the base in the normal gaming state without granting any special benefits at the time of the redrawing of the re-lottery, the occupancy rate decreases due to the decline in the player's gaming motivation, and by extension, As a result, the base cannot be recovered.

  In Patent Document 1, even if the degree of advantage to the player is different at the time of winning the re-lottery and at the time of the loss, the degree of advantage is not mentioned or suggested. It has not been done.

  In consideration of the above-mentioned facts, the present invention clarifies the degree of advantage for each player with respect to the privilege to be given to the player, and provides the best privilege according to the gaming state by combining benefits with different degrees of advantage. Thus, an object is to obtain a gaming machine that does not reduce the player's willingness to play and can prevent the store from suffering disadvantages.

According to the first aspect of the present invention, in a normal gaming state where the main purpose is to win a game ball to a special start port provided on the game board surface, the special symbol is triggered by the winning of the game ball to the special start port. When the lottery is executed and this special symbol lottery is won on the basis of the game specification that informs the result of the special symbol lottery by the stop symbol arrangement after producing the special symbol variation pattern expressing the variation of the symbol group of multiple columns In addition, a special game state in which more prize balls can be obtained in a shorter period of time than the normal game state, and a right can be obtained with a predetermined probability by winning the special symbol lottery. As a bonus game, during a predetermined number of normal games after the end of the special game state, a gaming machine that grants a main privilege that can acquire more prize balls than a normal game,
A sub-privilege with less winning balls than the main bonus is given during a predetermined number of normal games after the end of the special gaming state and before the main bonus is given.

  According to the invention of claim 1, when a special symbol lottery is won, the right of privilege lottery can be obtained, and during a predetermined number of normal games after the end of the special gaming state with a predetermined probability, rather than a normal game. Grant the main privilege that can win many prize balls.

  Further, in addition to the main privilege, a sub-privilege with less prize balls than the main privilege is given during a predetermined number of normal games after the end of the special gaming state and before the main privilege is given.

  Since the secondary benefit is less advantageous to the player than the main privilege, even if it is applied as a relief to the player, there is no disadvantage to the store.

  For example, there is a “base” as data for monitoring the operating state of a gaming machine. The base is the ratio of the total number of game balls to be paid out / injected (launched) in a state other than the special gaming state. If the value is 100 (%), profits and losses are generated for both the player and the store. Absent.

  Generally, in a gaming machine, when the main privilege is granted, the base is set to 100, and when neither the main privilege nor the secondary privilege is granted, the base is set to be about 20-30. . Therefore, by setting the base to be the above-mentioned middle, for example, about 50 to 60, as a secondary benefit, the player's expectation of winning the special symbol increases, and the store side has a certain amount of loss. However, the operation rate can be maintained, and as a whole, the player's willingness to play is not diminished, and the store does not suffer a great disadvantage.

The invention according to claim 2 is a special symbol triggered by the winning of the game ball in the special starting port in the normal gaming state mainly for the purpose of winning the gaming ball in the special starting port provided on the game board surface. When the lottery is executed and this special symbol lottery is won on the basis of the game specification that informs the result of the special symbol lottery by the stop symbol arrangement after producing the special symbol variation pattern expressing the variation of the symbol group of multiple columns In addition, a special game state in which more prize balls can be obtained in a shorter period of time than the normal game state, and a right can be obtained with a predetermined probability by winning the special symbol lottery. As a bonus game, during a predetermined number of normal games after the end of the special game state, a gaming machine that grants a main privilege that can acquire more prize balls than a normal game,
By winning the special symbol lottery, the right can be obtained with a predetermined probability, and during the predetermined number of normal games after the end of the special gaming state, a sub-privilege with less winning balls than the main bonus is obtained. It is characterized by giving.

  According to the invention described in claim 2, when a special symbol lottery is won, a privilege lottery right can be obtained, and during a predetermined number of normal games after the special gaming state is ended with a predetermined probability, from a normal game. Also grants the main privilege that can earn many prize balls.

  Similarly to the main privilege, a right can be obtained with a predetermined probability by winning a special symbol lottery, and during the predetermined number of normal games after the end of the special gaming state, a prize is awarded over the main privilege. Grants a sub-benefit with less ball acquisition.

  Since the secondary benefit is less advantageous to the player than the main privilege, even if it is applied as a relief to the player, there is no disadvantage to the store.

  For example, there is a “base” as data for monitoring the operating state of a gaming machine. The base is the ratio of the total number of game balls to be paid out / injected (launched) in a state other than the special gaming state. If the value is 100 (%), profits and losses are generated for both the player and the store. Absent.

  Generally, in a gaming machine, when the main privilege is granted, the base is set to 100, and when neither the main privilege nor the secondary privilege is granted, the base is set to be about 20-30. . Therefore, by setting the base to be the above-mentioned middle, for example, about 50 to 60, as a secondary benefit, the player's expectation of winning the special symbol increases, and the store side has a certain amount of loss. However, the operation rate can be maintained, and as a whole, the player's willingness to play is not diminished, and the store does not suffer a great disadvantage.

According to a third aspect of the present invention, in the first or second aspect of the present invention, there is provided a winning opening provided with a movable member that moves at least two positions for expanding or reducing the winning opening width on the surface of the game board. According to the invention of claim 3, the amount of the winning ball obtained by the normal game is a difference in expansion duration of the winning opening width of the winning opening by the movable member. The player can recognize that the degree of advantage is increased visually by setting the stage of advantage as the difference in the duration of expansion of the winning opening width of the special start opening by the movable member.

  According to a fourth aspect of the present invention, the game board surface according to the first or second aspect of the present invention, further comprising a movable member that moves at least two positions for expanding or reducing the winning opening width at the special starting port. The normal symbol lottery is executed based on the winning of the normal starting opening provided above, and the result of the normal symbol lottery is notified by the stop symbol arrangement after the normal symbol variation pattern production. When the lottery is won, the game further comprises a normal symbol game executing means for moving the movable member to a position for expanding the winning opening width for a predetermined period, and the winning of the winning ball by the movable member is caused by the amount of winning of the prize ball by the normal game. It is at least one of a difference in the extended duration of the winning opening width of the mouth, a difference in the winning probability of the normal symbol, or a difference in the normal symbol variation pattern production time. It is a symptom.

  According to the invention described in claim 4, it is an embodiment of the main privilege and the secondary privilege, the main privilege is at least one of increasing the probability of winning the special symbol lottery and shortening the special symbol variation pattern effect time And a combination of at least one of increasing the probability of winning the normal symbol and shortening the normal symbol variation pattern production time.

  The sub-privilege is configured at least one of increasing the probability of winning the normal symbol and shortening the normal symbol variation pattern effect time.

  Thereby, the difference of the degree of advantage to a player can be clarified.

  Further, the degree of advantage to the player (the amount of winning of the prize ball by the normal game) is determined depending on the difference in the extended duration of the winning opening width of the special start opening by the movable member or the difference in the winning probability of the normal symbol, or By making at least one of the differences in the normal symbol variation pattern production time, the player can recognize that the degree of advantage is increasing visually.

  The invention according to claim 5 is characterized in that, in the invention according to any one of claims 1 to 4, the main benefit is set to have a high probability of winning the special symbol lottery. .

  According to the invention described in claim 5, the main privilege is different from the normal game by increasing the probability of winning the special symbol lottery. Thereby, the difference of the degree of advantage to a player can be clarified.

  As described above, in the present invention, regarding the privilege to be given to the player, the degree of advantage to the player is clarified, and the privilege that is different in the degree of advantage is combined to give the optimum privilege according to the gaming state. Thus, there is an excellent effect that the player's willingness to play is not diminished and the store side can be prevented from suffering a disadvantage.

  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.

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, a character such as a big prize opening (variable prize device) 44, a special symbol start Game parts such as the mouth 46, the passing device 48, and the winning device 49 are attached, and the out mouth 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 (in some cases, only the passing device 48 on the left side in FIG. 2) serves as a starting trigger for the normal symbol display device 42A (normal symbol starting port), and a pachinko ball passes through the passing device 48. Then, the normal symbol lottery is executed, and in the case of winning, the display of the normal symbol display device 42A displays the winning, the electric tulip 47 is released, and the probability of winning the special symbol starting port 46 is physically increased. ing.

  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 special symbol lottery executed by this winning when the display unit 43 newly wins the special symbol starting port 46 while executing the symbol variation pattern effect. . Even when the special symbol start opening 46 is won during the jackpot process, the display unit 43 plays the moving picture pattern of the jackpot process effect, and is therefore subject to suspension. However, there is a limit to the number of suspensions (four in this embodiment), and winnings to the special symbol starting port 46 beyond this are not subject to suspension.

  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 at the special symbol starting port 46, a passing device 48 serving as a normal symbol starting port, a passing / winning sensor 172 provided at the winning device 49, and a big winning port 44. A big prize opening sensor 173 for detecting a pachinko ball that won a prize and an out ball detection sensor 179 for detecting a pachinko ball collected through the out opening 54 are 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.

  Further, the main control unit 150 includes a solenoid 174 for opening and closing an electric tulip 47 (see FIG. 2) as a movable member provided in the special symbol starting port 46, and a solenoid 175 for opening and closing the special winning opening 44. It is connected.

  The main controller 150 outputs information indicating the progress of the game to the hall computer via the board external terminal 190.

  Here, when the pachinko ball wins the special symbol start opening 46, the special symbol lottery is executed by detecting this with the start winning sensor 168. When winning, the special game is played from the normal gaming state. The game state is shifted to the state.

  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 result of the special symbol lottery, and the BGM at the time of the symbol variation pattern effect is output from the speaker 64. That is, the player can enjoy an effect including the result of the special symbol 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 192 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.

  Further, the payout control unit 154 sends payout information to the hall computer installed in the hall via the frame external terminal 194.

  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 about 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.

  Further, as described above, when the display unit 43 newly wins the special symbol starting port 46 during execution of the symbol variation pattern effect, and when the special symbol starting port 46 is won during the big hit process, the holding lamp The display number of 100 increases accordingly, and the number of lights increases (up to 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.

  Here, in the special symbol lottery, a lottery (privilege lottery) as to whether or not to grant a privilege is also performed in the normal game after the jackpot process is completed. This special lottery notification is in the form of “re-lottery” and once the special symbol lottery is won, the change is resumed and notified.

  Generally, in the bonus lottery (re-lottery), if the probability is ½ and the symbol is a number from 0 to 9, an odd array is hit and an even array is out.

  When this bonus lottery is won, in this embodiment, the probability (main privilege) is set as a probability variation. That is, if the probability of the special symbol lottery is “low (winning probability is about 1/300)”, the lottery in the high probability state is higher than the normal probability (winning probability is about 1/50). (Probability variation state). In this main privilege, the lottery result notification time (ordinary symbol variation time) of the normal symbol lottery is also shortened.

  As a result, when the bonus lottery (re-lottery) is won, the period until the next jackpot is shortened, which can be said to be advantageous for the player.

  By the way, when a special lottery (re-lottery) is lost, a player's willingness to play has been reduced since the main privilege as described above is not given. In order to solve this problem, it is considered to give another privilege. However, with the player's advantage alone, the loss on the store side is large and it is difficult to balance.

  Therefore, in this embodiment, when the bonus lottery is lost, the player's advantage level is lower than the main privilege, but the player's advantage level is higher than when the privilege is not given. I did it.

  Specifically, the normal symbol variation time is set to the medium speed state (medium) during the predetermined number of times (n) of the normal game after the end of the special game state (hit processing). The medium speed state refers to a state of an intermediate variation time between a normal symbol variation time (long) in a normal gaming state without a privilege and a normal symbol variation time (short) set in the probability variation state. The opening time of the electric tulip 47 at this time is equivalent to the normal gaming state when there is no privilege.

  The form of this sub privilege is set based on “base” which is one of data for monitoring the balance ratio of the pachinko machine.

  That is, as shown in Table 1, the base is about 20 to 30 in the normal gaming state without a privilege, which indicates that the player has fewer balls as the game progresses.

  On the other hand, the base game state to which the main privilege is given has a base of about 100, which indicates that the player does not lose the ball even if the game progresses.

  Here, in the normal game state to which the secondary privilege is given, the base is about 50 to 60, and this indicates that the player gradually loses the ball as the game progresses.

  FIG. 4 is a control block diagram functionally showing the lottery unit 200 for controlling the special symbol lottery, the normal symbol lottery, and the privilege grant based on the lottery result in the main control unit 150.

  As shown in FIG. 4, the function of the main control unit 150 includes a game execution control unit 202 and a lottery unit 200, and the game execution control unit 202 performs all the original games of the pachinko machine 10 (normal game, special game). , Command transmission to the production control unit 152 and the payout control unit 154, etc.).

  A lottery unit 200 is connected to the game execution control unit 202, and a special symbol lottery determination result, a special symbol variation pattern data, a normal symbol lottery determination result, and a normal symbol variation pattern data sent from the lottery unit 200. Based on the above, the game execution control unit 202 controls the progress of the game.

  The start prize sensor 168 is connected to the special drawing lottery management unit 204 in the lottery unit 200. The special drawing lottery management unit 204 is connected to a holding memory 206, and executes a special symbol lottery (special drawing lottery) based on the start winning from the start winning sensor 168 or the state stored in the holding memory 206. In order to do so, an execution signal is sent to the special drawing lottery execution unit 208.

  In the special drawing lottery execution unit 208, for example, a random number is acquired from a random number counter (not shown), and the random value data is sent to the special drawing lottery result determination unit 210.

  A special symbol value memory 212 is connected to the special symbol lottery result determination unit 210, and the special symbol lottery result determination unit 210 reads a winning value from the special symbol value memory 212, and the acquired random number value By comparing, it is determined whether the special symbol is present or not. In addition, whether the special symbol is won or not includes whether or not the main bonus is won.

  The special figure lottery result determination unit 210 is connected to a special figure lottery result recognition unit 214 and a special symbol variation pattern selection unit 216, and a special figure lottery determination result is transmitted to each of them.

  The special symbol variation pattern selection unit 216 selects a symbol variation pattern to be displayed on the display unit 43 based on the special symbol lottery determination result, and sends information specifying the selected symbol variation pattern to the game execution control unit 202. Send it out.

  On the other hand, the passage sensor 172 provided in the passage device 48 is connected to the ordinary drawing lottery execution portion 218 in the lottery portion 200 as a usual drawing start winning opening.

  The normal symbol lottery execution unit 218 executes a normal symbol lottery (normal symbol lottery) based on the start winning (pass) from the passage sensor 172. For example, a random number is acquired from a random number counter (not shown), and the random value data is sent to the usual lottery result determination unit 220.

  The ordinary symbol lottery result determination unit 220 is connected to a normal symbol value memory 222, and the ordinary symbol lottery result determination unit 220 reads a winning value from the ordinary symbol value memory 222, and the obtained random number value and By comparing, it is determined whether the symbol is normal or not.

  A normal symbol variation pattern selection unit 224 is connected to the general-drawing middle line result determination unit 220 so that a general-drawing lottery determination result is transmitted.

  In the normal symbol variation pattern selection unit 224, a variation pattern for displaying on the ordinary symbol display device 42A based on the result of the general symbol lottery determination (in this embodiment, since it is one digit display of 7 segments, only the variation time is displayed. Is selected), and information specifying the selected variation pattern is sent to the game execution control unit 202.

  Here, the special figure lottery result recognition unit 214 manages the determination history of the special figure lottery, for example, whether or not a privilege is granted when the current special figure lottery is a win (winning). Then, what kind of privilege is decided. The confirmed information is sent to the privilege grant unit 226.

  In the privilege granting unit 226, for example, when granting a privilege, the privilege granting unit 226 selects a main privilege or a sub-privilege, and when setting the main privilege, the special symbol variation pattern selection unit 216 is selected. Are instructed to select a short-time pattern, and the special symbol value memory 212 is instructed to set a high probability mode hit value.

  In addition, when setting a sub benefit, the normal symbol variation pattern selection unit 224 is instructed to select a short time pattern.

  The operation of the present embodiment will be described below.

  First, the flow of a normal game (special symbol game, ordinary symbol game) 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 the special symbol start port 46, a special symbol lottery is started with a predetermined probability. For example, a random number is acquired from a random number counter or the like. Note that the jackpot determination is to determine whether or not the winning / losing is performed by comparing the acquired random number value with a preset winning value.

  On the other hand, when a pachinko ball wins the passing device 48 serving as a normal symbol start port, a general drawing lottery is started with a predetermined probability.

  If the result of the regular drawing lottery is a win, the electric tulip 47 can be opened a predetermined number of times for a predetermined period to increase the probability of winning the special symbol starting port 46. Note that the operation of the electric tulip 47 during the normal game has an opening / closing frequency of 1 and an opening time of about 0.5 seconds. The operation of the electric tulip 47 during the special game has an opening / closing frequency of 2 times and an opening time of about 2 seconds.

  If the result of the special drawing lottery is a win, the execution of the jackpot process is started, and a special game state (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.

  Here, in the present embodiment, when the special gaming state that is the jackpot process as described above ends and returns to the normal gaming state, a privilege is given in the game in the normal gaming state. This privilege has a main privilege and a subsidiary privilege, and is set based on the result of a special drawing lottery.

  Hereinafter, the privilege granting control routine in the main control unit 150 will be described with reference to the flowchart of FIG.

  In step 300, a privilege default is set. This default means a state where there is no privilege in the so-called normal game. As setting A, the special drawing lottery probability is “low (non-probable change)”, and as setting B, the special drawing fluctuation time is “long (no short time). ) ”, The normal lottery variation time is set to“ long (no short time) ”as setting C, and the process proceeds to step 302.

  In step 302, it is determined whether or not the result of the special symbol lottery is winning (big win). If a negative determination is made, the process stands by until winning.

  If an affirmative determination is made in step 302, the process proceeds to step 304, where it is determined whether or not the jackpot process has ended in the game execution control unit (see FIG. 4). It will be in a standby state until it ends.

If an affirmative determination is made in step 304, the process proceeds to step 306, where it is determined whether or not the winning symbol of the special symbol lottery is a probable variation symbol. Moving to 308, the setting for giving the main privilege is performed. If the determination in step 306 is negative, that is, it is determined that the symbol is an uncertain variable, the process proceeds to step 320 (the processing after step 320 will be described later).
In step 308, which has shifted to affirmative in step 306, the main privilege is granted. That is, as setting A, the special drawing lottery probability is “high (probable change)”, as the setting B, the special drawing fluctuation time is “short (with short time)”, and as the setting C, the general drawing lottery fluctuation time is “short (with short time)” And the number of games at the main privilege is set as n, and the process proceeds to step 310. The number of games n may be infinite (no limit).

  After step 310, it becomes a normal game in a state where the main privilege is granted. In step 310, it is determined whether or not the result of the special symbol lottery is a win (big win). The process proceeds to step 312, and the number of games n is decremented (n ← n−1), and the process proceeds to step 314. In step 314, it is determined whether or not the number of games n has become 0. If the determination is negative, the process returns to step 310, and steps 310 and 312 are performed until the special symbol lottery is won or the number of games n is 0. 314 is repeated. If an affirmative determination is made in step 314, the process returns to step 300, the bonus is returned to the default value, and the normal game is executed.

  If an affirmative determination is made in step 310, the process proceeds to step 316, where it is determined whether or not the jackpot process has been completed in the game execution control unit (see FIG. 4). It will be in a standby state until it ends.

  If an affirmative determination is made in step 316, the process proceeds to step 318, where it is determined whether or not the winning symbol of the special symbol lottery is a probable variation symbol. Returning to 308, as long as the probability variation pattern continues, step 308 to step 318 are repeated.

  In step 318, if a negative determination, that is, a special symbol lottery is won, but it is not a probability variation symbol, the process proceeds to step 320.

  Step 320 is a process when a special symbol lottery with a non-probable variation symbol is won in Step 306 or Step 318, and a sub-benefits are granted.

  That is, in step 320, as the setting A, the special drawing lottery probability is “low (non-probable change)”, as the setting B, the special drawing fluctuation time is “long (no short time)”, and as the setting C, the normal drawing lottery fluctuation time is “ “Medium (There is a short time)” and the process proceeds to Step 322. “Medium” in the setting C indicates an intermediate value of the time range (short ← → long) of the fluctuation time.

  In step 320, the number of games n is set as a secondary benefit, but the number of games n does not have to be the same as the number of games n of the main privilege in step 308 described above.

  In step 322, it is determined whether or not the result of the special symbol lottery is a win (big win). If a negative determination is made, the process proceeds to step 324 and the number of games n is decremented (n ← n−1). Then, the process proceeds to step 326. In step 326, it is determined whether or not the number of games n has become 0. If the determination is negative, the process returns to step 322, and steps 322 and 324 until a special symbol lottery is won or until the number of games n becomes 0. 326 is repeated. If an affirmative determination is made in step 326, the process returns to step 300, the bonus is returned to the default value, and the normal game is executed.

  If an affirmative determination is made in step 322, the process proceeds to step 328, where it is determined whether or not the jackpot process has been completed in the game execution control unit (see FIG. 4). It will be in a standby state until it ends.

  If an affirmative determination is made in step 328, the process proceeds to step 330, where it is determined whether or not the winning symbol of the special symbol lottery is a probable variation symbol. Move to 308.

  In step 330, if a negative determination, that is, a special symbol lottery is won, but it is not a probable variation symbol, the process proceeds to step 332, and further, the main benefit (the player is granted for the sub-award granted in step 320). A privilege with a high degree of advantage.

  That is, in step 332, the special drawing lottery probability is “low (non-probable change)” as the setting A, the special drawing fluctuation time is “short (with short time)” as the setting B, and the general drawing lottery fluctuation time is “ "Short (with short time)", and the process proceeds to step 334. That is, the variation time is further shorter than the time given in step 320.

  In step 334, it is determined whether or not the result of the special symbol lottery is a win (big win). If a negative determination is made, the process proceeds to step 336 and the number of games n is decremented (n ← n−1). Then, the process proceeds to step 338. In step 338, it is determined whether or not the number of games n has become 0. If the determination is negative, the process returns to step 334, and steps 334 and 336 are performed until the special symbol lottery is won or the number of games n is 0. 338 is repeated. If an affirmative determination is made in step 338, the process returns to step 300, the privilege is returned to the default value, and the normal game is executed.

  If an affirmative determination is made in step 334, the process proceeds to step 340, where it is determined whether or not the jackpot process has ended in the game execution control unit (see FIG. 4). It will be in a standby state until it ends.

  If an affirmative determination is made in step 340, the process proceeds to step 342, where it is determined whether or not the winning symbol of the special symbol lottery is a probable variation symbol. Move to 308.

  In step 330, if a negative determination, that is, a special symbol lottery is won, but it is not a probability variation symbol, the process returns to step 332.

  As described above, in the present embodiment, when a special symbol lottery is won, and when this win is a win with a probability variation symbol, the special symbol lottery probability is set to a high probability state. In addition to the form of grants, when winning with a non-probable variation, the game will be advantageous to the player and will not increase the loss to the store side. Occupancy rate was maintained by granting special benefits. That is, since the player can expect to win the special symbol lottery again due to the secondary benefit, the game is continued. From the store side, the loss can be suppressed because the sub-score is less advantageous to the player than the benefit corresponding to the main benefit in the case of the uncertain variable win. If this is expressed as a base value, the base value in the normal gaming state without a privilege is about 20-30, 100 when the main privilege is granted, and 50-60 when the sub privilege is granted.

(Modification)
Hereinafter, modifications of the above embodiment will be described. In the above-described embodiment, a sub-privilege is first granted (step 320 in FIG. 5), and if the special symbol lottery is not won within the number of games when this sub-privilege is granted, a normal gaming state without a privilege is entered. It was made to return (return to step 300 by affirmation determination of step 326).

  On the other hand, in the modified example, as shown in FIG. 6, even when affirmative determination is made in step 326, that is, even when the special symbol lottery is not won for a predetermined number of games, In order to increase the degree of advantage step by step, the process proceeds to step 332.

  This modification is slightly more advantageous for the player than the above embodiment. Therefore, if each processing of FIG. 5 (embodiment) and FIG. 6 (modification) can be selected, for example, by operation on the store side (operation of a dip switch connected to the main control unit 150, etc.). The setting (prediction) based on the base value can be used as a countermeasure when the actual value is different.

  In the above-described embodiment and modification, the difference between step 320 and step 332 in FIGS. 5 and 6 is that during the normal game of the predetermined number of times (n) after the end of the special game state (hit processing). If the symbol change time is set to the medium speed state (medium) and the special symbol lottery is not won, the normal symbol change time is gradually shifted to the high speed (short) side and the special symbol change time is set to “ Shifted from “Long” to “Short”, but when a special symbol lottery with a high probability of special symbol lottery is won, sub-benefits will be granted to all players regardless of certainty / non-probable variation It may be. That is, in FIG. 5 and FIG. 6, step 306 is deleted and the routine proceeds from step 304 to step 320. Thereby, in the winning state of the special symbol lottery where the special symbol lottery is not highly probable, the benefits of step 320 and step 332 are always obtained.

  In addition, the timing for granting the privilege is not granted immediately after the end of the special game state (hit processing), but after the predetermined game, for example, after the predetermined number of normal games are performed. May be.
