Description

  The present invention relates to a gaming machine such as a slot machine that uses medals, coins and the like as gaming media.

  Conventionally, in gaming machines, particularly pachislot machines, a predetermined number of medals are inserted and a start lever is operated to execute a lottery, and a plurality of rows (usually three rows) in which a plurality of symbols are displayed on the circumferential surface. The symbol variation reel (symbol row display means) is rotated.

  The symbol variable reels that have started to rotate by the start lever can be basically stopped at the time that the player intends by operating the corresponding stop buttons.

  Here, when the start lever is operated, the internal lottery is executed and the winning / losing is determined, and the player performs the stop operation of each symbol variable reel by the stop button and wins the internal lottery. The rights will be exercised when the symbols corresponding to the winning are available.

  There are a small role and a big role, and for the exercise of the right for winning the small role, a predetermined game medium (hereinafter referred to as “medal”) is paid out.

  On the other hand, the exercising of the right of winning the big game shifts from the normal game state to a special game state of a predetermined number of times called a so-called bonus game (there is a regular bonus and a big bonus).

  The big bonus is composed of a plurality of regular bonuses. In the regular bonus game, the internal winning probability of a specific type of small role is extremely high, and a large number of medals can be obtained in a short period of time. .

  In this bonus game, Patent Document 1 reports the maximum number of valuable values (that is, medals) that a player can acquire at each time point in a predetermined gaming state (that is, a special gaming state) such as a big bonus. Thus, it is disclosed to improve the convenience of the player.

  Here, a game specification in which the end of the bonus game is set with the maximum payout number is considered. Therefore, reaching the maximum payout number with a small number of games increases the net increase number most.

More specifically, when the total number of payouts is 360 and the largest payout number among the small roles is 15 (hereinafter referred to as “15 small roles” (small role A)), more than 345 medals The bonus game (regular bonus) is determined to end when is paid out. For this reason, if 15 small payouts are continuously awarded, 15 games x 24 games = 360, and the number of games inserted for 24 games (3 games per game, 3 x 24 = 72 games). The subtracted 288 sheets is the maximum net increase.
JP 2002-159628 A

  However, in the bonus game, the 15 small combinations (probability of about 1 / 1.01 to 1 / 1.1) that are most likely to be won internally are other small combinations (hereinafter referred to as “5 small combinations”). (Small B)) may win internally (probability is 1/10 to 1/100).

  If a so-called rare winning combination such as the above 5 winning combination wins and wins, the condition set based on the maximum payout number described above (the bonus game ends when more than 345 payouts are made) On the other hand, a fraction is generated, and after that, there is a difference in the number of net increase depending on whether or not the five winning combinations are to be won when they are won internally.

  Therefore, it is preferable to determine whether or not to win a prize based on the probability value of each small role and notify the player. In this case, the appearance status of “5 small roles” Although it follows the respective probabilities, in a short span (one bonus game), there is a slight error with respect to the probability that is the theoretical value, so high-precision notification cannot be performed.

  In consideration of the above facts, the present invention simulates the winning pattern of a small role in a single major role game (bonus game) to determine whether or not to win a small role that is internally won in a state closer to reality. It is an object to obtain a gaming machine that can determine whether or not the product is good and bad.

  According to the first aspect of the present invention, lottery is executed with the start operation as a trigger, and a plurality of symbol sequences start to be changed. When a symbol is placed in a stopped state corresponding to the winning combination by a stop operation of a symbol row, a winning combination for executing a payout of a predetermined game medium as a privilege or a lottery probability of the small role as a privilege is high. A gaming machine that can be a big prize winning that can be executed in the state of the game, and in the case of winning the big prize, one small role A set as the payout number X with the maximum payout number Tmax as an end condition And one or more small roles B set to a payout number Y smaller than the payout number X of the small role A, respectively, in a big role game specification that can be internally won with a winning probability higher than the predetermined winning probability. Large to play games based A game execution control means, a pass / fail determination means for determining pass / fail based on the stop operation when the small combination B is won internally based on a simulation result under the major role game specifications, and the pass / fail determination And a notifying means for notifying the determination result of the means.

  According to the first aspect of the present invention, when the small role B is elected internally during the major role game control by the major role game execution control means, the pass / fail judgment means determines whether or not the winning role of the small role B is determined by the major role game specification. Based on the simulation results under.

  By performing the simulation, it is possible to grasp a more realistic appearance state of the small role B, and it is possible to determine pass / fail with high accuracy.

  The notification means notifies the player of the determination result by the pass / fail determination means. Thus, the player can intentionally avoid (remove) the winning combination of the small combination B won internally and obtain the maximum net increase in the current situation.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, a multiple of the payout number X of the small combination A is the maximum payout number Tmax.

  According to the invention described in claim 2, since the maximum payout number Tmax is a multiple of the payout number X of the small combination A, in order to obtain the maximum net increase number, it is sufficient to continue to win only the small combination A. A fraction is generated by winning the small role B, and it is necessary to determine whether to continue to play the small role A in subsequent games or to eliminate the fraction by taking the small role B (or to minimize the fraction). Become.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the simulation is performed in advance by performing a lottery for the number of times for approximating the theoretical probability of each small role. An average number of internal winnings is obtained, and the pass / fail determination means determines the pass / fail of the small role B based on the average internal winning number of each small role obtained from the result of the simulation. .

  According to the invention described in claim 3, it is theoretically possible to determine whether or not the winning combination of the small role B is based on the internal winning probability of the small role A and the small role B. In a short span of big game, there are cases where the probability value does not match. Therefore, by executing the lottery for the number of times that approximates the theoretical probability of each small role in advance by simulation to obtain the average internal winning number of each small role, Appearance can be grasped, and the accuracy of quality determination can be increased accordingly.

  As described above, according to the present invention, it is determined whether or not to make a winning combination for an internal winning in a more realistic state by simulating a winning pattern for a small role in one big game (bonus game). It has an excellent effect of being able to make a good / bad decision and notify.

  Also, at the bottom of the display window 314, a 7-segment display 315A for displaying the number of paid-out medals as game media of the pachislot machine 300, a display for setting the remaining number of jack games and the game state (six levels), etc. A section 315B and a 7 segment display section 315C for displaying the number of credits are provided.

  The operation unit 306 has an upper portion protruding forward, a medal insertion unit 320 is provided at the right end of the upper surface of the protruding portion, and is pressed down from the left end of the upper surface when paying out credits in order. A settlement button 103, a single bet (insertion) button 352A, and a MAX bet (maximum input) button 352B. Further, a start lever 354, stop buttons 356A, 356B, 356C, and the like are provided in this order from the front left end of the protruding portion.

  The payout unit 310 includes a medal discharge port 326 and a tray 328 that receives a medal discharged from the medal discharge port 326.

  The three reels 350 </ b> A, 350 </ b> B, and 350 </ b> C are rotated so that symbols can be seen sequentially from the display window 314. The direction of rotation appears to move from top to bottom in FIG.

  Here, among the symbols that can be seen from the display window 314 when the rotation is stopped, a line connecting the centers of the symbols arranged in the middle row, a line connecting the centers of the symbols arranged in the upper row, and a line connecting the centers of the symbols arranged in the lower row The combination of the symbols stopped on the five active lines of the two lines respectively connecting the centers of the symbols arranged on the two diagonal lines indicates the result of the game.

  Of the five lines, which line is the effective line is determined by the number of medals inserted, and when one medal is bet, the line connecting the centers of the symbols arranged in the middle row is the effective line. If three medals are bet, all lines are valid lines.

  The stop buttons 356A, 356B, and 356C are provided below the symbol changing unit 316 and correspond to the reels 350A, 350B, and 350C. That is, the rotation of the corresponding reels 350A, 350B, and 350C can be stopped by operating the stop buttons 356A, 356B, and 356C by the player.

  Further, by operating (tilting) the start lever 354 provided on the left side of the stop buttons 356A, 356B, 356C, the reels 350A, 350B, 350C start to rotate. This rotation is normally such that the three reels 350A, 350B, 350C start rotating simultaneously.

  Further, the operation timing by the start lever 354 is an internal lottery timing which will be described later, and the winning (winning) / off is determined by the operation of the start lever 354.

  Of the lines, a line aligned in a horizontal line in the upper row is used as a reference line for stop control (including slip control) to be described later. That is, stop control is performed based on the positional relationship between the reference line and the center line of the symbol located on the reference line.

  The reels 350A, 350B, and 350C do not stop between symbols, and are always controlled to stop at the symbol pitch.

  More specifically, if there is a stop operation when the center line of the first symbol on the reference line exceeds the reference line, the reels 350A, 350B, and 350C cannot be reversed. The control for stopping the second symbol (less than the maximum symbol pitch) is a so-called bitter stop criterion immediately after the second symbol until the center line of the next second symbol coincides with the reference line.

(Control system)
FIG. 2 schematically shows a control block diagram for controlling the operation of the pachislot machine 300.

  The control system of the pachislot machine 300 is configured with the main control unit 100 as the center, and the main control unit 100 identifies medals inserted from the medal insertion unit 320, and the number and types of medals inserted (incorrect or And a stop button 356A, 356B, 356C, a MAX bet button 352B, and a single bet button 352A corresponding to the start lever 354 and the above-described reels 350A, 350B, and 350C, respectively. In addition, a settlement button 103 for returning a medal stored (credited) inside the gaming machine when the game is stopped is connected via a sensor (not shown) that detects an operation state.

  The main control unit 100 also includes a main control circuit 110 including a CPU. The main control circuit 110 mainly includes a RAM 128 that temporarily stores game progress and the like, and various programs. A stored ROM 130 is connected, and a clock pulse generation circuit 124 that generates a clock pulse that is a reference for the operation of the main control circuit 110 is connected via a frequency divider 126.

  Further, a random number generator 120 and a random number latch circuit 122 are connected to the main control circuit 110. The main control circuit 110 controls the random number generator 120 in synchronization with the clock pulse input through the frequency divider 126 to sequentially generate random numbers, and the random number latch circuit 122 generates the random number. Latch and get the random number.

  In the pachislot machine 300, an internal lottery is performed by the main control unit 100 to determine whether a major role or a small role is won at the operation timing of the start lever 354. In the main control circuit 110, the start lever 354 is operated. Then, the random number value generated by the random number generator 120 is acquired by the random number latch circuit 122 (random number). Then, a lottery result is derived according to the random number.

  If the internal lottery is a win (combination), the player can win the number of medals according to each symbol when the winning symbols are obtained by the stop operation by the subsequent stop buttons 356A, 356B, 356C. The gaming state is advantageous to the player according to the symbol.

  Here, there are small roles and big roles as roles. Among these, the major players include a big bonus (hereinafter referred to as “BB” as appropriate) and a regular bonus (hereinafter referred to as “RB” as appropriate), and the degree of advantage to the player differs in the game corresponding to each. A game corresponding to RB (hereinafter referred to as “RB game” as appropriate) is composed of a plurality of small role games, and a game corresponding to BB (hereinafter referred to as “BB game” as appropriate) It is configured to include an RB game that can be won a plurality of times within a range where the number of acquired medals does not exceed the upper limit. Therefore, as a matter of course, the RB game is more advantageous to the player than the small role game, and the BB game is more advantageous to the player than the RB game. As the upper limit, the maximum payout number is set, and the game ends when the number exceeds the number obtained by subtracting the payout number of the small role with the largest payout amount (hereinafter referred to as “small role A”) during the RB game. It becomes. More specifically, when the maximum payout number is 360 and the payout number of the small role A is 15, the game ends when the payout number exceeds 345.

  In addition, a motor drive circuit 132 is connected to the main control unit 100, and the motor drive circuit 132 includes left (L), middle (C), and right (R) reel motors 106A, 106B, Each of the left, middle, and right reels 350A, 350B, and 350C is connected via 106C.

  Further, the main control unit 100 is connected to a reel position detection circuit 134 for detecting the rotational positions of the three reels 350A, 350B, and 350C. The positions of 350A, 350B, and 350C can be always grasped.

  Further, in the pachislot machine 300, the symbol variation by the symbol variation unit 316 is started at the operation timing by the start lever 354. When the start lever 354 is operated, the main control unit 100 operates the motor drive circuit 132. The reel motors 106A, 106B, and 106C are respectively started to rotate, and the three reels 350A, 350B, and 350C are rotated, and the three stop buttons 356A, 356B, and 356C are operated on the basis of the subsequent operations. The rotation of the reels 350A, 350B, and 350C is stopped.

  Here, in the main control unit 100, when the rotation of the reels 350A, 350B, and 350C is stopped based on the stop operation by the stop buttons 356A, 356B, and 356C, the slip control of a predetermined number of frames is performed according to the result of the internal lottery. Is supposed to run.

  In other words, when the internal lottery is off and the stop button 356A, 356B, 356C is operated at the timing of the stop operation in which the symbol that stops only on the winning line is stopped on the active line, the stop in this symbol is intentionally stopped. In order to avoid this, the stop position is shifted (kicked off), and control is performed so that the stop position is stopped by the off symbol arrangement.

  In addition, when the internal lottery is won, even if the winning symbol does not stop at the timing of the stop operation operated by the player, if the winning symbol is within the predetermined time or the predetermined number of symbols, the winning symbol is intentionally placed on the active line. The stop position is shifted (retracted) so as to stop together.

  By kicking and pulling in the above, it is possible to make the internal lottery result and the game result uniform, and even if the stop operation timing is slightly shifted, it is possible to align the winning symbols, It prevents people from being lost.

  Here, in the slip control including kicking and pulling in as described above, the amount of slip (the number of sliding symbols) varies depending on the result of the internal lottery.

  The reels that have already stopped (generally, when the middle reel 350B is stopped, the left reel 350A is in a stopped state, and when the right reel 350C is stopped, the left reel 350A and the middle reel 350B are in a stopped state. ) Also varies depending on the state of the symbol arrangement (upper, middle, lower).

  Therefore, in the main control circuit, the stop operation timing by the stop buttons 356A, 356B, and 356C (specification of the symbols to be bittered to the reference line) and the slip for each of the internal lottery results and the determined symbol rows A slip control table in which the number of frames is associated is stored, the corresponding slip control table is read based on the result of the internal lottery and the determined symbol sequence, and slip control is executed.

  The main control unit 100 is connected to a hopper drive circuit 136 for operating a hopper 138 provided inside the pachislot machine 300. The hopper 138 stores medals, and the main control unit 100 pays out medals from the hopper 138 via the hopper drive circuit 136 in accordance with the stop pattern specified by the output from the reel position detection circuit 134. Executed.

  Further, a medal detection sensor 140 that detects medals paid out from the hopper 138 is disposed in the vicinity of the hopper 138 and is connected to the main control unit 100 via a payout completion signal circuit 142. The payout completion signal circuit 142 determines whether or not the payout is completed based on the detection signal from the medal detection sensor 140, and generates a payout completion signal when it is determined that the payout is completed. Is input.

  When the payout completion signal is input from the payout completion signal circuit 142, the main control unit 100 ends the medal payout by the hopper 138 via the hopper driving circuit 136.

  Further, a display lamp drive circuit 144 is connected to the main control unit 100, and the 7-segment display unit 315A, the display unit 315B, the 7-segment display unit 315C, and the activation line described above are connected via the display lamp drive circuit 144.

The lottery unit 180 executes an internal lottery with the operation of the start lever 354 after a predetermined number of medals have been inserted (bets) as a trigger.

  The lottery unit 180 acquires a random value in synchronization with the operation of the start lever 354, and sends the random value to the winning combination / symbol determination unit 184 via the table selection unit 182.

  The table selection unit 182 stores a role / symbol table (see FIG. 4) in which information indicating a role / symbol corresponding to a numerical value that can be acquired by the lottery unit 180 is stored for each gaming state of the pachislot machine 300. . As the gaming state of the pachislot machine 300, for example, normal game, during BB internal winning, during RB internal winning, normal game during BB operation, during RB internal selection during BB operation, RB gaming, CT (challenge time) Middle class.

  The table selection unit 182 obtains information indicating the current gaming state (in general gaming, during an RT game, when a major role flag is established, and major roles (BB, RB, etc.)) from the gaming state control unit 186, and for each gaming state described above. A role / symbol table for which a role / symbol should be determined is selected from the provided role / symbol tables.

  Based on the role / symbol table selected by the table selection unit 182, the winning role / symbol determination unit 184 displays the winning role (small role (including replay), major role (RB, BB, CT)) and the winning symbol. The determined winning combination and winning symbol are input to the gaming state control unit 186.

  The gaming state control unit 186 is connected to a gaming program memory 188 in which data indicating various programs corresponding to the gaming state of the pachislot machine 300 is stored. The game state control unit 186 mainly controls the game state by reading and executing game program data corresponding to the game state from the game program memory 188 as appropriate by the game execution control unit 186A.

  The game program memory 188 stores data indicating a normal game program and data indicating a major game program. For example, in the normal game state, the normal game program data is read from the game program memory 188. In the case of the big game state, the big game program data is read according to the internal winning state of BB and RB and the respective game states of BB and RB, and processing is executed based on each program data.

  On the other hand, the main control unit 100 is configured to include a reel drive control unit 194. Based on the start operation of the start lever 354, after a lapse of 4.1 seconds from the start of the previous game, the motor drive unit 132 is provided. Then, the reel motors 106A, 106B, and 106C are driven to start rotation of the reels 350A, 350B, and 350C.

  Further, the reel drive control unit 194 performs stop control for stopping the rotation of the reels 350A, 350B, and 350C based on the operation of the stop buttons 356A, 356B, and 356C.

The reel drive control unit 194 recognizes the respective rotation positions of the reels 350A, 350B, and 350C, stops the reels 350A, 350B, and 350C in consideration of the slip control, and stops the reels 350A, 350B, and 350C that have stopped. The symbol array is sent to the gaming state control unit 186.

  Based on the symbol arrangement of the reels 350A, 350B, and 350C that have been stopped, the gaming state control unit 186 confirms whether or not a winning combination has been won. If the winning combination is a small winning combination, a predetermined payout is made and a winning combination is made. If the role is replay, replay control is executed. If the role is a big role, the game execution control unit 186A reads the big role game program from the game program memory 188. If the role is a CT game role, the CT game specification program is read. Executed.

  In addition, the regular bonus game program and the big bonus game program are separately stored in the major player program, and are selectively read based on the elected major player.

  In the regular bonus program, a maximum of 12 games (maximum number of games) can be executed in the state that the lottery probability of the small role is higher than the lottery probability during the normal game as the right exercise. The regular bonus game ends when the player wins a maximum of eight times (maximum number of winnings) during any of these 12 games.

  In this regular bonus game, it is possible to increase the number of nets by increasing the aforementioned small role A (a small role with a payout number of 15). However, a small role other than this small role A (for example, payout) There is also a possibility that a small combination with 5 sheets (hereinafter referred to as “small combination”) will win internally and win a prize.

  On the other hand, in the big bonus program, a regular bonus game can be executed as a right exercise until the total number of payouts in the big bonus reaches a preset upper limit number (360 pieces as described above), and the number obtained in the big bonus game is preset. If the upper limit number is reached, the big bonus game ends even if the regular bonus game is being executed.

  In addition, a flag memory 192 is connected to the gaming state control unit 186 via the flag management control unit 190, and the internal winning state of the combination corresponding to the winning result of the internal lottery described above is managed by the state of the flag. Yes.

  Each flag is established by winning by internal lottery. Generally, the state of the small role flag disappears in one game (flag is not established) (invalidity of winning), but the state of the flag of the major role is then changed to each reel. 350A, 350B, and 350C are stopped and the main character symbols are displayed in a predetermined arrangement on the display window 314, and are maintained until winning the main character (winning carry-over).

  Note that the flag memory 192 is connected to the reel drive control unit 194 described above, and the state of the flag stored in the flag memory 192 is based on the operation of the stop buttons 356A, 356B, and 356C by the reel drive control unit 194. This is applied as a parameter for pull-in or kick-out slip control during stop control.

  As one of the above-mentioned information regarding the game, in this embodiment, whether or not the internal winning prize (small role A or small role B) should be won in a bonus game (particularly, RB in BB). The determination is appropriately notified according to the progress state of the game.

  This is because the lottery probability and payout number of the small role A, the lottery probability and payout number of the small role B, and the maximum payout number are set, and the number of times approximate to the lottery probability (in this embodiment, 10,000 times). ) Game simulation (= simulation, that is, a simulation experiment) is searched for a winning pattern that is most advantageous to the player (a pattern with the maximum net increase), and is notified based on the search result (see Table 1).

  Summing up specific numerical values, the small combination A has a payout number of 15 (the maximum value of the small combination payout number in the present embodiment), and the small combination B has a payout number of 5 and the maximum payout number. Is 360, and the number of inserted games per game is three.

  Under the above conditions, since the bonus game is over when 360-15-15 = 345, the small combination A ( (15 cards).

  Therefore, the optimal winning is that the small role A (15) is won 24 times (15 × 24 = 360) from the start of the bonus game. For this reason, if there is a prize for the small role B, the above calculation will be distorted. Therefore, every time the small role B is elected internally, it is determined whether or not a prize should be awarded in order to achieve the maximum net increase. There is a need.

  In order to make this judgment accurately and accurately, a simulation is executed.

  Table 1 shows that the bonus for the small role A is 1 / 1.0010095, the random probability for the small role B is 1 / 100.005, and a bonus of 10,000 times assuming that the current small role B is won once. It is a game simulation result.

Based on Table 1 above, the content of notification is determined with reference to Table 2 below.
(1) Pattern A: Assuming that the winning small role B is won in the first game of the bonus game, assuming the winning small role B, the number of winning points for each small role until the end of the BB is simulated. The average number of B is about 0.23 times. Since this is less than one time, the number of internal winnings of the small role B is set to 0, and the number of times of the small role B won this time is set to one.

Referring to Table 2, which shows the combination in which the net increase in the number of internal winnings for the small role B is maximum, when the number of internal winnings in the small role B is 1, the net increase is larger when the small role B is removed. Therefore, it is reported that there is a high possibility that the small part B is better earned.
(2) Pattern B: After winning a small role B once, a combination that maximizes the net increase in the number of internal winnings of the small role B regardless of the number of internal winnings of the small role B regardless of the number of internal winnings of the small role B Referring to Table 2 shown, since the number of net increases is larger when winning a small combination B twice than when winning a small combination B, a notification is given to encourage the small combination B to win.
(3) Pattern C: After winning the small role B twice, the winning combination of the small role B, regardless of the number of internal winnings of the small role B, the combination that maximizes the net increase in the number of internal winnings of the small role B Referring to Table 2 shown, since the net increase in the number of winning three times is larger than that of winning small role B twice, a notification is given to encourage the small role B to win.

  Similarly, when winning a small role B three times, four times, five times, and six times and then winning a small role B internally, it is determined from Table 2 whether or not to win the small role B. Inform. Note that “◯” in Table 2 indicates the optimum combination for the number of internal winnings of each small role B.

  As described above, since the net increase differs depending on how to win the small role, as described above, the pass / fail judgment result based on the simulation is displayed (notified) on the LCD 313 in advance to eliminate the disadvantage of the player. Is possible.

  FIG. 5 is a block diagram functionally showing the control in the sub-control unit 150 for notifying the types of small roles to be won and the number of times each.

  As shown in FIG. 5, the RB entry information in the BB is input to the reset unit 200 as information from the main control unit. The reset unit 200 is connected to the history data storage unit 202. When the in-BB RB entry information is input to the reset unit 200, the reset unit 200 resets history data in the previous BB in-RB game stored in the history data storage unit 202.

  On the other hand, lottery result information is input to the internal winning combination determination unit 204 as information from the main control unit. The internal winning combination determination unit 204 is connected to the history data reading unit 206, the history data update unit 208, and the notification information image creation unit 210.

  When the internal winning combination determination unit 204 determines that the small combination A has been internally won based on the lottery result information, an update instruction signal is sent to the history data update unit 208. Based on this update instruction signal, the history data update unit 208 updates the history data stored in the history data storage unit 202.

  When the internal winning combination determination unit 204 determines that the small combination A has been internally won based on the lottery result information, a notification image generation instruction signal is sent to the notification information image generation unit 210. Based on the notification image creation instruction signal, the notification information image creation unit 210 creates an image (see FIG. 6A) representing that the small role A has won internally.

  On the other hand, when the internal winning combination determining unit 204 determines that the small combination B has been internally won based on the lottery result information, a winning / bad determining instruction signal is sent to the history data reading unit 206. Based on this winning / bad determination instruction signal, the history data reading unit 206 reads the history data from the history data storage unit 202 and sends it to the winning / bad determination unit 212.

  A simulation data memory 214 is connected to the winning / bad determination unit 212. The simulation data memory 214 stores information relating to the above-described Tables 1 and 2, and is read out according to an instruction from the winning / bad determination unit 212.

  Based on the current game history and simulation data, the winning / non-winning determination unit 212 determines whether or not the internal winning small role B should be won, and based on the determination result, the notification image creation instruction signal is transmitted to the notification information image. The data is sent to the creation unit 210. On the basis of the notification image creation instruction signal, the notification information image creation unit 210 has an image (see FIG. 6 (B)) in which the small role B is internally won and prompts winning of the winning combination, or an image prompting avoidance of winning (see FIG. 6 (C)).

  The notification information image creation unit 210 is connected to the display driver 216, and sends the created notification information image data (any one of FIGS. 6A to 6C) to the display driver 216.

  The display driver 216 controls the LCD 313 to execute display based on the input notification information image data.

  The operation of this embodiment will be described below.

  First, the flow of normal games will be described.

  In the state where the medal is credited (or in the state where the medal is inserted from the medal insertion unit 320), the betting of the medal is completed by the operation of the single bet button 352A or the maximum bet button 352B, or the medal insertion unit When a bet is completed by inserting a medal from 320, the start lever 354 can be operated.

  When the start lever 354 is operated, an internal lottery is performed by the lottery unit 180 simultaneously with this operation, and the reels 350A, 350B, and 350C start rotating under the control of the reel drive control unit 194.

  The result of the internal lottery is transmitted from the winning combination / symbol determination unit 184 to the gaming state control unit 186. The gaming state control unit 186 updates and stores the flag state of the flag memory 192 according to the result of the internal lottery via the flag management control unit 190.

  Thereafter, when the player operates the stop buttons 356A, 356B, and 356C, the stop operation stops the rotation of the reels 350A, 350B, and 350C. However, according to the flag stored in the flag memory 192, the slip control is taken into consideration. Then, stop control of the reels 350A, 350B, and 350C is executed so that the corresponding symbol is pulled into the predetermined position or kicked off from the predetermined position. That is, the reel drive control unit 194 selects the stop control table according to the state of the flag stored in the flag memory 192 and the gaming state by the gaming state control unit 186, and the flag is established. In this case, the winning symbol can be stopped by an accurate pressing timing. Further, a slight shift in the stop operation timing is corrected by slip control. On the other hand, when the flag is not established, the reels 350A, 350B, and 350C are caused to slip even if they are pushed, so that they do not stop at the winning symbol.

  Next, when all the reels 350A, 350B, and 350C are stopped, a winning determination is made as to whether or not a winning is made based on the stopped symbols. When winning, the winning combination is also determined.

  If it is determined by this determination that the major player has won a prize, the bonus game control of the big bonus (BB) or regular bonus (RB) is executed (exercises the right) according to the stop pattern, and it is determined that the player is a minor. In this case, predetermined payout control preset for the small combination is executed.

  Here, an LCD 313 is provided above the display window 314 for viewing the rotation and stop states of the reels 356A, 356B, and 356C. Usually, an image such as a notice of the lottery result is displayed. During the bonus game (RB in RB), the symbol corresponding to the internal winning combination and the quality of the winning of the symbol (see the “x” mark shown in FIG. 6C) are displayed (notified). .

  In other words, in the BB RB game, the winning combination of the small combination A is basically high, and most of the small combinations A are internally won. However, in rare cases, the small combination B may be internally won. In this case, whether or not the internal winning winning small role B should be won depends on the gaming state (the number of winning times of the small role B) at that time. Therefore, the disadvantage of the player can be eliminated by guiding the acquisition of the optimal small combination in the present situation.

  In other words, until the maximum payout number is exceeded, there will be a slight difference in the net increase depending on the player's operation.

  For this reason, a simulation is executed in advance on the condition that the number of net increases is a condition in which the number of payouts for the small role A in the RB game in BB, the number of payouts for the small role B, the maximum number of payouts, and the number of medals inserted into the game. The winning pattern that is most advantageous to the player (the pattern that gives the largest net increase) is searched from among them, and notification according to the progress of the game is executed.

  FIG. 7 is a flowchart showing notification control in the BB in-game RB game. This flowchart is executed when the RB is activated during BB.

  In step 250, the history data is reset, and then the process proceeds to step 252 to determine whether or not a lottery result has been input.

  If an affirmative determination is made in step 252, the process proceeds to step 254, an internal winning combination is determined, and the process proceeds to step 256.

  In step 256, it is determined whether the winning combination is a small combination A or a small combination B. If it is determined that the small combination A is determined in this step 256, the process proceeds to step 258 to create a notification information image relating to the small combination A (see FIG. 6A), and the process proceeds to step 268 described later.

  On the other hand, when it is determined that the small combination B is determined in step 256, the process proceeds to step 260 to read the history data, and then the simulation data is read in step 262, and the process proceeds to step 264.

  In step 264, the winning / non-winning determination is performed based on the read history data and simulation data.

  Based on the winning / bad decision result, in step 266, a notification information image relating to the small combination B is created (see FIG. 6B or FIG. 6C), and the process proceeds to step 268.

  In other words, as shown in Tables 1 and 2, depending on the number of wins for the small role B up to now, the number of net increase is greater when winning the internal winning small role B, or the amount of net increase is higher when avoiding the win. There are many changes. For this reason, each time the small combination B is won internally, the winning / bad decision is made based on the history data up to that time and the simulation data. When winning a prize, the symbol corresponding to the small role B is displayed as it is as shown in FIG. 6B, and when winning is avoided, the symbol corresponding to the small role B is displayed as shown in FIG. 6C. An “x” mark is displayed so as to overlap with.

  In step 268, the history data is updated, and then the process proceeds to step 270 to display the notification information image created, and the process proceeds to step 272.

  In step 272, it is determined whether the BB has ended (whether the maximum payout number has been reached). If the determination is negative, the process returns to step 252 to repeat the above steps. If the determination at step 272 is affirmative, this routine ends.

  As described above, in the present embodiment, in the BB in-game RB game, the maximum payout number is set as the end condition, and in addition to the small winning combination (small winning combination A) that can be won normally, it is possible to rarely win. Should a small role (small role B) be executed in advance for a simulation, and based on this simulation data and historical data before the small role B has been internally won, the small role B should be won Therefore, it is possible to accurately and accurately notify whether to avoid, and to eliminate the disadvantage of the player.

  In this case, the reason for executing the simulation is that a single BB has a large error with respect to the theoretical probability, and in order to avoid this error, actual data that is approximate to the probability is created. . Thus, for example, 22.9998 / 0.2342≈ as shown in Table 1 for the theoretical probability ratio (probability A probability {1 / 1.01} / probability B ’s probability {1 / 100≈99.0090). It becomes 98.2058, and although it is slight, discrimination in a state close to reality is possible.

  In the game specification change, when the probability of a small combination is changed, a simulation may be executed in the same manner as in Table 1 based on the probability of a small combination at that time.

  For example, Table 3 shows that a lottery probability of the small role A is 1 / 1.111 and a lottery probability of the small role B is 1 / 10.00092, and 10,000 times assuming a situation where the current small role B is won once. It is a bonus game simulation result.

  Based on Table 3, with reference to Table 2 described above, as in the case of the pattern A in the simulation of Table 1, the optimal winning combination acquisition pattern (good / bad winning when the winning combination B is won internally) May be notified.
