Abstract

<P>PROBLEM TO BE SOLVED: To average winning ratios in winning lines when winning in two or more kinds of winning lines is possible and restrain an increase in the memory capacity of a bit data saving area or the like. <P>SOLUTION: Even when the winning of one winning combination in two or more winning lines is possible, the consumption of the memory capacity can be reduced by using single bit data. In this case, since winning combinations eligible for stopping timing point addition are changed for every one game, a stopping operation with the same timing does not lead to the same stop control. Consequently, randomness becomes significant. Concentration on winning lines due to the application of single bit data can be avoided and allocation can be realized with nearly equal probability because the setting of score differences for all patterns and the stopping of necessary patterns in a necessary position become possible by performing point addition (basic point addition, readiness-to-win point addition, stopping timing point addition) to each of stopped patterns. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a gaming machine such as a slot machine that uses medals, coins, game balls and the like as game 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 bonus and a big bonus, and for the exercise of the right for winning the small bonus, a predetermined game medium payout is executed. In addition, the small role includes replay (replay), and at the time of replay, it is considered that a payout equivalent to the game medium thrown in for the game is made, and a new game medium is thrown in. Without replay rights.

  On the other hand, exercising the right of winning a major role is called a so-called bonus game (there is a regular bonus and a big bonus) from the normal gaming state after a predetermined game medium payout is executed for the role. , Transition to a predetermined number of special gaming states.

  Note that, when the player performs a stop operation using the stop button, slip control for a predetermined number of frames is executed according to the result of the internal lottery.

  In other words, when the stop button is operated at the stop timing of the symbol that stops only in the case of winning when the internal lottery is off, the stop operation is performed in order to avoid intentionally stopping at this symbol for the stop operation timing. The position is shifted (kicked off), and control is performed so as to stop at the off symbol arrangement.

  Here, when the internal lottery is won, even if the winning symbol does not stop at the stop operation timing operated by the player, if the winning symbol is within the predetermined number of symbols (currently a maximum of 4 frames slips), this hit is intentionally made. Control (shift) of shifting the stop position so that the symbols stop together.

  By kicking and pulling in, you can have consistency with the lottery results, and even if the timing of the stop operation is slightly shifted, you can align the winning symbols, allowing players to miss It is preventing in the range.

  As described above, since the number of sliding frames varies depending on the result of the internal lottery, the slip control stores a table corresponding to each situation in advance.

  As the table, a bit table in which the number of sliding frames is expressed in bits (binary system) has been proposed (see Patent Document 1).

  Table 1 shows the second example when the upper, middle and lower reels (generally the left reel) that are stopped for the first time at the time of internal winning of the bell stop at the bell, bamboo, and replay symbols, respectively. A bit table of reels (generally, medium reels) stopped at the second time is shown.

  In this bit table, one frame slip is expressed by “0”, and a stop frame is expressed by “1” (see Table 3).

  In the case of Table 1, there are two winning lines in which the bell symbols are arranged as a tempered line, the upper row and the lower right row. Therefore, conventionally, the bit data in which the bell symbol of the middle reel is located in the upper row and the bit data in the middle row. 2 types of bit data are prepared and selected by, for example, lottery.

However, since two types of bit data are prepared, a corresponding memory capacity is required. Therefore, the two types of bit data are simply combined.
JP-A-11-178987

  However, when the two types of bit tables are simply combined, the stop ratio between the upper stage and the middle stage corresponding to the above-mentioned winning line (upward line, lower right line) is not 1: 1 but the bias occurs. Then, when the two types of bit tables are combined, the upper stage: middle stage has a ratio of 16: 5, and the bias becomes particularly significant.

  In consideration of the above facts, the present invention can average the winning ratio in each winning line when two or more winning lines can be won, and a memory such as a bit data storage area. An object is to obtain a gaming machine capable of suppressing an increase in amount.

  The invention described in claim 1 is provided with reels arranged in three rows that start rotational driving based on a starting operation, and a continuous three of a plurality of symbols arranged on the peripheral surface of the reels at an equal pitch. By displaying the symbols one by one, the symbols can be displayed in a 3 × 3 matrix, and the display section includes at least five winning lines including a horizontal line of at least the upper line, the middle line, and the lower line, and a diagonal line. The game machine having the display device set in (2), wherein the lottery means for executing a lottery of a preset combination based on the start operation timing and the symbol corresponding to the winning combination by the lottery means are stopped. The game execution control means for executing the payout of the game medium corresponding to the winning combination and the stop operation timing for each reel when it can be aligned with any of the winning lines by operation. Accordingly, within the range of the predetermined number of sliding frames with the symbol pitch as a unit frame set in advance for each reel, at least based on the result of the lottery by the lottery means, Stop control means for stopping the rotational drive of the reel so as to notify the result of the lottery, and the stop control means performs the lottery result of the combination for the reel for which the stop operation has been performed for the first time. Is set based on the lottery result of the combination and the symbol arrangement state on the display portion of the reel that has already stopped, and the stop operation Bit data storage means for storing binary bit data composed of a stop code that is an identification code that is stopped in a state of time and a slip code that is an identification code that executes slipping for one frame And a first addition means for adding points based on the result of the winning lottery and the symbol arrangement state on the display section of the reels that have already stopped, executed prior to the second and subsequent stop operations. When the symbols corresponding to the winning combination can be aligned by a plurality of winning lines, the symbol is executed after the second and subsequent stop operations and corresponds to the symbols within the predetermined number of sliding symbols at the stop operation timing. Second biting means for selectively adding points to avoid bias in the winning line, and points for changing bit data selected for adding points by the second adding means A stop symbol setting for setting the symbol corresponding to the highest score among the total score added by the object changing means and the first addition means and the second addition means as a stop purpose. It is characterized by comprising a means.

  According to the first aspect of the present invention, the three rows of reels start to rotate by the starting operation. In addition, at the time of this starting operation, a lottery is performed by the lottery means, and winning / losing of the winning combination is determined.

  In the game execution control means, when the symbol corresponding to the winning combination can be aligned with any of the winning lines by the stop operation, the game medium corresponding to the winning combination is paid out.

  Here, in the stop control means, as a basic operation, based on the stop operation timing for each reel, a stepwise range of predetermined number of sliding frames using the symbol pitch set in advance for each reel as a unit frame. The rotation of the reels is stopped so that the result of the winning lottery is notified on the winning line based on the result of the winning lottery by the lottery means.

  In other words, even if it deviates from the optimal stop operation timing, it is possible to achieve the same state as the optimal stop operation timing by slip control, so that it becomes easy to win a winning combination, and beginners who are not good at stop operation can stop It is possible to correct the disparity with skilled workers who are good at operation.

  By the way, in the slip control by the stop control means, for example, with a single bit data (stop code and slip code set corresponding to each symbol), the variation of the symbols to be stopped is monotonous or the winning line is biased. Will occur.

  In view of this, the stop control means adds a score based on the stop code and the slip code, and executes a control in which the symbol corresponding to the highest score is the total score obtained by the addition.

  That is, in the first addition means, it is executed prior to the second and subsequent stop operations, and points are added based on the result of the winning lottery and the symbol arrangement state on the display unit in the already stopped reels. .

  The second adding means is executed after the second and subsequent stop operations when the symbols corresponding to the winning combination can be aligned by a plurality of winning lines, and the predetermined sliding piece at the stop operation timing is executed. For the bit data corresponding to symbols within a few ranges, points are selectively added in order to avoid bias of the winning line.

  Further, the point addition changing unit changes the bit data selected for adding points by the second addition unit.

  The stop symbol setting means sets the symbol corresponding to the highest score among the total points scored by the first addition means and the second addition means as the stop purpose.

  Thus, by adding points, it is possible to set the priority order of the bit data corresponding to each symbol, not as simple binary data. Thereby, it is possible to obtain a highly varied gaming state by subsequent calculation (addition processing) without increasing the storage capacity (storage of the base bit data).

  In addition, since the point addition target is changed by the point addition target changing means, even if the stop operation is performed at the same timing, different stop control (change of the stop target symbol) is executed, and the stop at the biased symbol is reduced. The

  According to a second aspect of the present invention, in the first aspect of the invention, when the number of points to be selectively and fixedly added by the second addition means is k points, the first addition means , N (k> n) points are given as the basic points of the slip code of the bit data read from the storage means, and m points (m> k + n) are given as the basic points of the stop code, and there is a possibility of winning. It is characterized in that p point (p ≧ k + m) is given to bit data corresponding to.

  According to the second aspect of the present invention, it is necessary to set the relative relationship (number relationship) of each score when adding points so that no inconsistency occurs due to the added points.

  If the number of points added by the second adding means is k, the basic point n of the slip code in the first adding means is a point satisfying k> n, and the basic point m of the stop code is m> k + n. Is a score satisfying.

  Further, the point p added to the bit data corresponding to the symbol that may be won is a point satisfying p ≧ k + m.

  This makes it possible to effectively (most preferentially) handle the points for correcting the bias of the winning line by the second adding means.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein when the point addition target changing means defines a period from the start operation to the next start operation as one game, The point addition target is changed for each one game.

  According to the invention described in claim 3, the change of the point addition target of the second addition means by the point target change means is made for each game. For example, when there are two types of selection patterns, it is avoided that the same stop control is executed even if there is an internal winning of the same combination in succession and there is a stop operation at the same timing.

  As described above, according to the present invention, when two or more types of winning lines can be won, it is possible to average the winning ratio in each winning line, and to store the amount of memory such as a bit data storage area. It has an excellent effect that the increase in the amount can be suppressed.

The display window 314 includes a transparent region that is integrally formed with the display panel unit 312.

  Inside the display window 314, there is disposed a symbol variation portion 316 configured with three spinning reels 350A, 350B, and 350C as main portions.

  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, and a medal insertion unit 320 is provided at the right end of the upper surface of the protruding portion. Further, the operation unit 306 is pressed down when credits are sequentially paid out from the left end of the upper surface. A settlement button 103, a single bet (insertion) button 352A, and a maximum 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.

  Which of the five lines is the effective line depends on the number of medals invested, 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.

  In addition, a random number generator 120 and a random number sampling 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 sampling circuit 122 generates the random numbers. Get random numbers and sample them.

  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 sampling circuit 122 is instructed to acquire, sample, and output a random number, thereby deriving a lottery result according to the random number input from the random number sampling circuit 122.

  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.

  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, 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 stop button 356A, 356B, 356C is operated at the stop timing at which the symbol that stops only on the winning line is stopped on the active line when the internal lottery is off, intentionally avoiding the stop at this symbol Therefore, control is performed so that the stop position is shifted (kicked off) and stopped at the off symbol arrangement.

  Also, when the internal lottery is won, even if the winning symbol does not stop at the stop timing operated by the player, if the winning symbol is within the predetermined number of symbols, the winning symbol is intentionally stopped on the active line. Performs control to shift (pull in) the stop position.

  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 this embodiment, a bit data table) associated with the number of frames is stored, the corresponding slip control table is read based on the result of the internal lottery and the determined symbol sequence, and the slip control is executed. Like to do.

  Furthermore, among the symbols that have already been stopped, the symbol that has been selected for the internal lottery may be in a state where it is possible to win in a plurality of winning lines. In order to average the probability of winning, a score for setting a priority is assigned to the slip amount information read from the slip control table used for the slip control. The slip control table and the point addition control will be described later.

  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.

  Position detection sensors 198A, 198B, and 198C are attached to the reels 350A, 350B, and 350C, respectively, and are connected to the reel drive control unit 194 via the reel position detection circuit 134. 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 winning combination is replay, replay control is executed, and if the winning combination is a leading role, the gaming execution control unit 186A reads the leading role gaming program from the gaming program memory 188 and executes it.

  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.

  On the other hand, in the big bonus program, a regular bonus game can be executed with high probability as an exercise of rights, and even if the regular bonus game is being executed if the number obtained in the big bonus game reaches a preset upper limit number The big bonus game ends. In the present embodiment, the winning probability of the small role in the big bonus game is almost the same as that in the normal game.

  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).

  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.

  FIG. 5 shows a functional block diagram for executing stop control of the reels 350A, 350B, and 350C in consideration of slip control in the reel drive control unit 194.

  The stop buttons 356A, 356B, 356C are connected to the reference line upper symbol determination unit 200. The reference line upper symbol determination unit 200 recognizes the symbol position when the stop buttons 356A, 356B, and 356C (respectively) are operated by a signal from the reel position detection circuit 134, and the symbol at the time of so-called bitter stop. Identify. The reference line is the upper line.

  The specified bittering stop information is sent to the point calculation unit 201.

  On the other hand, the flag memory 192 is connected to the flag determination unit 204. The flag determination unit 204 determines the state of the flag at the current time (current game), and sends information on the determination result to the table reading unit 206.

  A slip control table memory 208 is connected to the table reading unit 206. The slip control table memory 208 stores a plurality of bit data tables 208 (x) (x = 1, 2,..., N−1, n) set for each gaming state (internal lottery result). Yes.

  The table reading unit 206 selects the corresponding bit data table 208 (X) based on the determination result from the flag determination unit 204, reads it, and sends it to the point calculation unit 201.

  In the point calculation unit 201, based on the bit data assigned to each symbol, a basic point calculation for adding a preset number of points (n, m) and a template (for example, the left reel 350A has already stopped, A symbol addition calculation for adding a score (p) to a symbol that can be awarded by stopping the middle reel 350B this time, and a bitter stop symbol determined by the stop operation timing of the stop button 356B or 356C. 0th frame, 0th frame, 2nd frame, 4th frame as first group, 1st frame, 3rd frame as 2nd group A stop timing point calculation for adding points (k) to each symbol of the group is executed.

In the present embodiment, the group is changed by the following selection (1) (addition target changing means).
(1) Selection for each game The operation from the start lever 354 to the operation of the next start lever 354 is defined as one game, and the first group or the second group is defined for each game. Select alternately.
(2) Selection for each same winning combination Each time the same winning combination is won, the first group or the second group is alternately selected.
(3) Lottery for each game A lottery (1/2) is performed for each game, and the first group or the second group is selected according to the lottery result.
(4) Lottery for the same winning combination Every time the same winning combination is won, a lottery (1/2) is performed, and the first group or the second group is selected according to the lottery result.

  In addition, regardless of the type of winning combination, a group may be selected alternately or by lottery every time a winning combination is won, or may be selected at random, or in any case fixed. If it ’s not the right one,

  The point calculation result executed by the point calculation unit 201 is sent to the slip control amount selection unit 202.

  The slip amount selection unit 202 selects a slip amount (the number of slip frames) based on the score state of each symbol and sends it to the drive signal output unit 210. Accordingly, the drive signal output unit 210 controls the motor drive circuit 132 to stop the reel motors 106A, 106B, and 106C at a predetermined time.

  The driving signal output unit 210 is connected to the gaming state control unit 186 (see FIG. 3) and a start lever 354, and the reel motors 106A, 106B, and 106C are also controlled during the start control of the reels 350A, 350B, and 350C. Control the drive.

  6 and FIG. 7, the flow of the point addition process will be described by taking the case where the middle reel 350B is stopped as an example with respect to the above basic point calculation, the point addition point, and the stop timing point. FIG. 6 shows the correlations of Table 2, Table 3, Table 4, and Table 6 shown below when the first group is selected, and the description content is Table 2, Table 3, Table 4, Table 6. 6 is the same.

  FIG. 7 is a correlation diagram similar to FIG. 6 at the time of selecting the second group. Table 5 is applied instead of Table 4 in FIG. 6, and Table 7 is applied instead of Table 6. The

  Table 2 shows the arrangement of the stop symbols of the left reel, and shows that the upper row is stopped at “red 7”, the middle row is “watermelon”, and the lower row is stopped at “bell”. Therefore, it can be seen that there are two types of winning lines for “Bell”: a descending line and a diagonal line that rises to the right.

  When the symbol stops on the left reel 350A, the bit data shown in Table 3 is read out on the middle reel 350B.

  Based on this bit data, +1 as a score n is assigned to the bit data “0” and +4 as a score m is assigned to the bit data “1” as basic points.

  This basic score is for preventing the bit data “1” from exceeding the score of the bit data “1” even if a stop timing score (described later as +2 points) is added to the bit data “0”.

  Next, what is executed is a tempering point addition, and normally +8 points as a score p are added to the bit data “1”.

  In Table 3, the tempering points (score p) are executed for all the bit data “1”. However, the portion where no tempering is performed may be intentionally set to the bit data “1”. . This is a method used when selecting an outcome at the time of missing, and no bit points are given to the bit data “1” for which such a setting has been made because no tempering is performed.

  When the calculation of the basic points and the tempering points is completed (the calculation is a very short time), the middle reel 350B can be stopped, and the stop button 356B is operated at the player's discretion.

  Table 4 shows the states of the stop timing addition points for the coma within the slip control range in each of the 21 symbols given to the middle reel 350B when the first group is selected.

  That is, at the stop operation timing, there are a total of 5 symbols that can be stopped, including so-called bittering-stopped symbols. In each frame, +2 points are added as stop timing points for the symbols of the 0th frame, the 2nd frame, and the 4th frame belonging to the first group.

  As a result of the above points, +14 points out of 5 symbols determined by all stop operation timings of the middle reel 350B are the highest score.

  Table 5 shows the states of the stop timing addition points for the coma within the slip control range in each of the 21 symbols given to the middle reel 350B when the second group is selected.

  That is, at the stop operation timing, there are a total of 5 symbols that can be stopped, including so-called bittering-stopped symbols. In each frame, +2 points are added as a stop timing additional point for the symbols of the first frame and the third frame belonging to the second group.

  As a result of the above points, +14 points out of 5 symbols determined by all stop operation timings of the middle reel 350B are the highest score. However, the arrangement No. in the middle reel 350B. When the stop operation is performed at the timing of 9 (see Table 3), +12 points is the highest score.

  In the slip control, as viewed from the lower end of the column (biter stop position), the design having the first highest score is stopped, and the results are shown in Tables 6 and 7. .

  In Table 6, stop symbols in the upper, middle, and lower stages of the middle reel 350B when the first group is selected are represented by numbers shown in Table 3, and positions for “bell” to be tempered (middle stage) (Or the bottom). In Table 7, a stop at the middle stage is expressed as “middle”, and a stop at the lower stage is described as “lower”.

  As shown in Table 6, the ratio between the middle stage and the lower stage of the stop position of “Bell” is 10:11, and it can be seen that the stop is performed at a probability of almost ½.

  In other words, the priority for each symbol in the slip control is determined by the basic points, the tempering points, and the stop timing points, so that the bias of the winning line due to a single bit data is avoided.

  In Table 7, stop symbols in the upper, middle, and lower stages of the middle reel 350B when the second group is selected are represented by the numbers shown in Table 3, and the positions for the “bell” to be tempered (middle stage). (Or the bottom). In Table 6, a stop at the middle stage is denoted as “middle”, and a stop at the lower stage is denoted as “lower”.

  As shown in Table 7, the ratio between the middle stage and the lower stage of the stop position of “Bell” is 10:11, and it can be seen that the stop is performed at a probability of almost ½.

  In other words, the priority for each symbol in the slip control is determined by the basic points, the tempering points, and the stop timing points, so that the bias of the winning line due to a single bit data is avoided.

  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, when stop operations by the stop buttons 356A, 356B, and 356C are sequentially executed, the reels 350A, 350B, and 350C are sequentially stopped, but when the left reel 350A is stopped, the internal determined before that If the result of the lottery is winning and the symbol corresponding to the winning combination is stopped at any one of the stopped symbols (upper or lower) of the left reel 350A, there is a possibility that a plurality of winning lines may be won. For example, if the small winning bell is elected internally and the bell stops at the lower stage of the left reel 350A, it can be aligned with the downward winning line or the diagonally rising winning line.

  In this case, conventionally, two types of bit data that can be won are prepared for each winning line, and a means for applying any one of the bit data by lottery has been taken, so there is a possibility of winning to each winning line. Although the ratio is 1: 1, the amount of memory consumed for one role is increased by the amount of bit data required.

  On the other hand, in the present embodiment, a single bit data is allocated to one role to reduce the amount of memory, and the bit data code allocation state and the subsequent stop operation (medium reel) The point calculation processing is executed for each of the symbols to be stopped by a stop operation by the stop button 356B of 350B) or the like. By considering the correlation of the points added, it is possible to make the winning ratios to a plurality of winning lines equal (1: 1 in the case of two types of winning lines).

  The point calculation processing routine will be described below with reference to the flowchart of FIG.

  This flowchart describes the process from the stop of the left reel 350A to the stop of the middle reel 350B.

  In step 250, it is determined whether or not the left reel 350A has stopped. If a negative determination is made, the routine ends. If an affirmative determination is made in step 250, the routine proceeds to step 252 where it is determined whether or not the flag F has been reset.

  If a negative determination is made in step 252, the process proceeds to step 256, the flag F is reset (0), and the process proceeds to step 258. If the determination in step 252 is affirmative, the process proceeds to step 254, the flag F is set (1), and the process proceeds to step 258.

  That is, the flag F is inverted between “0” and “1” for each game. In the flowchart of FIG. 8, the stop of the left reel 350A is used as a reverse trigger, but it has the same meaning as the operation of the start lever 354 to the next start lever, which is the actual definition of one game. .

  In step 258, the stop symbols (upper, middle, lower) of the left reel 350A are determined. For example, as shown in Table 2, it is determined that “red 7”, “watermelon”, and “bell” have stopped in the upper, middle, and lower stages, respectively.

  In the next step 260, based on the result of the internal lottery, bit data for stopping the middle reel 350B in consideration of the slip control is read (see Table 3), and the process proceeds to step 262.

  In step 262, it is determined whether there are multiple pay lines. In other words, if the left reel 350A is stopped as shown in Table 2 while the small role “Bell” is internally won, “Bell” can be won on either the down line or the diagonal line that goes up to the right. Therefore, it can be said that there are multiple winning lines.

  If a negative determination is made in this step 262, that is, if the winning line is one line (or a loss in the internal lottery), the routine proceeds to step 264 and normal slip control is executed.

  If an affirmative determination is made in step 262, the process proceeds to step 266, and first, basic point addition processing is executed.

  In the basic point addition process, n points (here, +1 point) are added to the read bit data “0”, and m points (here, +4 points) are added to the bit data “1”.

  In the next step 268, a tempering process is executed.

  In the tempering point addition process, p points are awarded for the tempering symbol that allows the winning line formed between the symbol of the left reel 350A and the symbol of the left reel 350C to be won by stopping the middle reel 350B. (+8 points here) is added.

  If there is a stop operation by the stop button 356B of the middle reel 350B after such basic addition and tempering addition (affirmative determination in step 270), the process proceeds to step 272 and the state of the flag F (reset (0)) Whether or not).

  If an affirmative determination is made in step 272, it is determined that the game is an odd-numbered game, the process proceeds to step 274, stop timing addition processing is executed for the first group, and the process proceeds to step 278.

  On the other hand, if a negative determination is made in step 272, it is determined that the game is an even-numbered game, the process proceeds to step 276, a stop timing adding process is executed for the second group, and the process proceeds to step 278.

(Stop timing process for the first group)
In the stop timing addition process for the first group, the symbols (5 frames in total) within the slip control range are specified on the basis of the bitter stop design at the stop timing (see Table 4), and 0 frames are included in the range. K points (here, +2 points) are added to the second, fourth and fourth frames.

  By executing the basic point adding process, the tempering point adding process, and the stop timing adding process, a score difference occurs in the symbols of the five frames.

(Stop timing process for the second group)
In the stop timing addition process for the second group, the symbols within the slip control range (5 frames in total) are specified on the basis of the bitter stop symbol at the stop timing (see Table 5), and one frame among them Add k points (here, +2 points) to the third and third frames.

  By executing the basic point adding process, the tempering point adding process, and the stop timing adding process, a score difference occurs in the symbols of the five frames.

  In the next step 278, slip control is executed so that the symbol having the highest score is stopped at the middle or lower stage of the middle reel 350B, and this routine is finished.

  By specifying the stop symbol based on the score as described above, as shown in Tables 6 and 7, the “bell” can be stopped at the middle or lower stage at each of the 21 frame stop timings. If it stops at the middle stage, the diagonal line that rises to the right becomes the winning line, and if it stops at the lower stage, the lower line becomes the winning line.

  Looking at the winning probabilities (assigned ratios) of these two types of winning lines, there are 10 patterns on the right-up diagonal line and 11 patterns on the lower line, and either winning line is selected at approximately 1: 1. . In other words, it is possible to select a pay line that has no bias.

  As described above, in the present embodiment, even when a single winning combination can be won on two or more winning lines, the consumption of memory is reduced by using a single bit data. can do. In this case, since the stop timing addition target is changed for each game, even if the stop operation is performed at the same timing, the same stop control is not performed, so that the randomness becomes remarkable.

  In addition, by applying a single point data (basic points, tempe points, stop timing points) to each stop symbol for the bias of the winning line by applying a single bit data, each symbol is scored It is possible to set a difference and stop a desired symbol at a desired position (upper, middle, lower, or kick), avoiding a bias in the winning line, and realizing an allocation with an almost equal probability it can.

  In other words, priorities for each symbol in slip control are determined by basic points, tempering points, and stop timing points, so that the “bell” has been placed on two types of winning lines (middle and lower) at almost the same rate. In order to stop, two types of bit data had to be prepared, but a single bit data enables stop control in an equivalent state.

  In this embodiment, the stop control of the middle reel 350B when the left reel 350A is stopped has been described. However, the present invention is also applicable to the stop control of the right reel 350C when the left reel and the middle reels 350A and 350B are stopped. Is possible.
