Abstract

The ratios of prize winnings of the prize wining lines are averaged when prize winnings of two or more prize winning lines are possible and an increase of the memory capacity of bit data storage area is prevented. Even when prize winnings of two or more prize winning lines are possible for one prize, the consumption of the memory capacity can be reduced by using single bit data. The disproportion of the prize winning line due to application of single bit data is avoided by performing point addition (basic point addition, on-the-pot point addition, stop timing point addition) on the stop symbols. By setting a point difference to each symbol, it is possible to stop a desired symbol at a desired position (upper row, middle row, lower row, or kick-out). Consequently the disproportion of prize wining line is prevented, and allocation with almost equal probability is realized.

Description

Game machine

Technical field

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.

Background art

Conventionally, in gaming machines, particularly pachislot machines, a lottery is executed by inserting a predetermined number of medals and operating a start lever, and multiple rows (normally 3 The symbol variation reel (symbol row display means) in the row is rotated.

[0003] The symbol-variable reels that have started rotating by the start lever can be basically stopped at the time that the player intends by operating the corresponding stop buttons. .

[0004] Here, when the start lever is operated, an internal lottery is executed and the Z-off is determined, and the player performs the stop operation of each symbol variable reel by the stop button, and the internal lottery is won. In such cases, the rights will be exercised when the symbols corresponding to the winning are available.

[0005] There are a small role and a big role in winning, and for the exercise of the right of winning a small role, a payout of a preset game medium is executed. In addition, the small role includes replay (replay), and at the time of replay, it is assumed that the same payout as the game medium thrown in for the game is made, and a new game medium is thrown in. You have the right to replay without doing anything.

[0006] On the other hand, the exercise of the right to win a major role is a so-called bonus game (there is a regular bonus and a big bonus) from the above-mentioned normal gaming state after a predetermined game medium payout is executed for that role. It shifts to a special game state called a predetermined number of times.

[0007] It should be noted 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.

[0008] That is, 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 out, In order to avoid stopping at the handle, the stop position is shifted (kicked), and control is performed to stop at the disengaged symbol array.

[0009] Here, when the internal lottery is won, even if the winning symbol does not stop at the stop operation timing operated by the player, even if the winning symbol is within the predetermined number of symbols (currently a maximum of 4 frames slips), Intentionally, the stop position is shifted (retracted) so that all the winning symbols stop together.

[0010] By kicking and pulling in, it is possible to have consistency with the result of the lottery, and even if the stop operation timing is slightly shifted, it is possible to align the winning symbols. Protect the device from spillage as much as possible.

[0011] This slip control has a different number of sliding frames depending on the result of the internal lottery as described above.

A table corresponding to each situation is stored in advance.

[0012] As a table, a bit table in which the number of sliding frames is expressed in bits (binary system) has been proposed (see Patent Document 1).

[0013] Table 1 shows, for example, the upper, middle and lower reels that are stopped for the first time during the internal selection of the bell (the left reel) stop at the bell, bamboo, and replay designs, respectively. The bit table of the reel (generally, the middle reel) that is stopped for the second time is shown.

[0014] In this bit table, one-frame slip is represented by "0", and a stop frame is represented by "1" (see Table 3).

[0015] In the case of Table 1, there are two winning lines where the bell symbols are aligned as a tempered line, the upper row and the lower right row, so conventionally, the bell symbol of the middle reel is located in the upper row and the bit data located in the upper row. Two types of bit data, such as bit data to be prepared, were prepared and selected by, for example, lottery.

[0016] [Table 1] Bit reel for middle reel

Left reel (Upper: Bell, Middle: Bamboo, Lower: Re: Play) Symbol 1 Symbol With or without slipping With or without slipping Pattern With or without slipping With or without slipping

[0017] However, since two types of bit data are prepared, a corresponding amount of memory capacity is required, so this can be dealt with by simply combining the two types of bit data.

Disclosure of the invention

Problems to be solved by the invention

[0018] However, if the two types of bit tables are simply combined, the stop ratio of the upper and middle stages corresponding to the above-mentioned winning line (upward and right-down lines) is not 1: 1 but biased. In the example of Table 1 above, when the two bit tables are combined, the ratio of upper: middle is 16: 5, and the bias becomes particularly significant.

[0019] 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 can store the bit data. It is an object to obtain a gaming machine that can suppress an increase in the amount of memory.

Means for solving the problem

[0020] The invention described in claim 1 includes a plurality of reels that start rotation driving based on a starting operation, and has a plurality of symbols arranged on the peripheral surface of the reels at a predetermined pitch. Display that can be displayed on the display unit, and at least a plurality of winning lines are set on the display unit. A gaming machine equipped with a device, wherein a lottery means for executing a lottery of a preset role based on the start operation timing, and a symbol corresponding to the winning combination by the lottery means are displayed on the winning line by a stop operation. If each of the reels can be aligned, the game execution control means for executing the payout of the game medium corresponding to the winning combination, and the respective reels are set in advance based on the stop operation timing for each reel. In the range of the predetermined number of sliding frames with the symbol pitch as a unit frame, based on at least the result of the lottery by the lottery means, the result of the lottery is notified on the winning line, Stop control means for stopping the rotational driving of the reel, and the stop control means is based on the lottery result of the combination for the reel that was stopped for the first time. The sliding frame number table storage means for storing the number of sliding frames at each stop operation timing of the reel, and the result of lottery for reels that have been stopped after the second time In addition, a stop code that is set based on the symbol arrangement state on the display unit in the reel that has already stopped and is a stop code that is stopped in the state at the time of the stop operation, and an identification code that executes slipping for one frame. Bit data table storage means for storing any one of binary bit data composed of slip codes in correspondence with a design, and executed prior to the second and subsequent stop operations, the result of the lottery drawing, and Based on the symbol arrangement state on the display in the already stopped reels, each symbol is given a numerical value that the stop code is superior to the slip code under relative quantity comparison. Executed after the second and subsequent stop operations when the basic numerical value adding means to be added to the stop code and slip code of the bit data and the symbols corresponding to the winning combination can be aligned by a plurality of winning lines. In the stop operation timing, a numerical value is selectively and fixedly added to avoid the bias of the winning line for the bit data corresponding to the symbols within the range of the predetermined number of sliding symbols. 1 numerical value adding means, and stop symbol setting means for setting the symbol positioned most dominantly among the final numerical values added by the basic numerical value adding means and the first numerical value adding means as a stop purpose. It is characterized by having prepared.

According to the first aspect of the present invention, a plurality of rows, for example, three rows of reels start rotating by a start operation. In addition, at the start operation, a lottery by lottery means is executed and the winning combination The defeat is decided.

[0022] 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. Execute.

[0023] Here, in the stop control means, as a basic operation, based on the stop operation timing for each reel! /, Stepwise using the symbol pitch set in advance for each reel as a unit frame. Within a predetermined number of sliding symbols, the rotation of the reels is stopped so as to notify the result of the winning lottery on the winning line based on at least the result of the winning lottery by the lottery means.

[0024] That is, 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 is easy to win a winning combination and the stop operation is not good. It is possible to correct the disparity between beginners and skilled people who are good at stopping.

By the way, in the slip control by the stop control means, for example, with a single bit data (a stop code and a slip code set corresponding to each symbol), the variation of the symbols to be stopped is monotonous or a prize is received. Line deviation occurs.

[0026] Therefore, in the stop control means, based on the stop code and the slip code, a numerical value in which the stop code is superior to the slip code is given to each symbol under a relative quantity comparison. It is added to the stop code and slip code of the bit data. A control is executed to stop the symbol corresponding to the most dominant numerical value obtained by this addition.

That is, the basic numerical value adding means is executed prior to the second and subsequent stop operations, and the numerical value is calculated based on the result of the winning lottery and the symbol arrangement state on the display unit in the already stopped reel. Append.

[0028] The first numerical value 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 stop operation timing at the stop operation timing. For the bit data corresponding to symbols within a predetermined number of sliding frames, a number is selectively and fixedly used to avoid bias in the winning line. Add a value.

[0029] The stop symbol setting means sets the symbol positioned most dominantly among the final numerical values added by the basic numerical value adding means and the first numerical value adding means as the stop purpose.

[0030] In this way, by adding numerical values, it is possible to set a priority order in which bit data corresponding to each symbol is not as simple binary data. This makes it possible to obtain a gaming state with high nomination by subsequent calculation (for example, point addition processing) without increasing the storage capacity (storage of the base bit data).

[0031] The invention according to claim 2 is characterized in that the basic numerical value adding means includes the bit data table when the first numerical value adding means selectively and fixedly adds points. Memory means power n (k> n) points are given as the basic point of the slip code of the read bit data, m points (m> k + n) are given as the basic point of the stop code, and there is a possibility of winning. It is characterized by giving p point (p≥k + m) to the bit data corresponding to.

[0032] According to the invention described in claim 2, it is necessary to set the relative relationship (number relationship) of each score when adding calories so that no contradiction occurs due to the addition of numerical values. Is

[0033] If the number of points added by the first numerical value adding means is k points, the basic point n of the slip code in the basic numerical value adding means is a point satisfying k> n, and the basic point m of the stop code Is a score satisfying m> k + n.

[0034] Also, the point p added to the bit data corresponding to the symbol that may be won is p.

≥k + n is satisfied.

[0035] With this, it is possible to effectively (most preferentially) handle the points for correcting the bias of the winning line by the first numerical value adding means.

The invention's effect

[0036] As described above, according to the present invention, when two or more types of winning lines can be awarded, it is possible to average the winning ratios in the respective winning lines and to store bit data. It has an excellent effect that an increase in the amount of memory such as an area can be suppressed. BEST MODE FOR CARRYING OUT THE INVENTION

[0037] (Schematic configuration of pachislot machine)

A pachi-slot machine 300 as shown in FIG. 1 includes a main body 302 and an operation / decoration portion 303 as an opening / closing cover provided in front of the main body 302.

The operation / decoration unit 303 can be classified into a decoration unit 304, an operation unit 306, and a payout unit 310 from the top.

[0039] The decoration unit 304 is attached with a display panel unit 312 through which a printed picture or character is transmitted and illuminated by turning on a backlight unit (not shown). As a part of the decorative portion 304, a three-dimensional decorative lamp 304A is also provided in the left-right direction above the decorative portion 304. In addition, speakers 305R and 305L are provided in the vicinity of the decorative lamp 304 for reproducing production sound and the like.

[0040] The display panel unit 312 of the decoration unit 304 includes a liquid crystal display (LCD) 313 for displaying a moving image for presentation, and a display window 314 for displaying a rotating display symbol. The display window 314 is formed of a transparent region that is integrally formed with the display panel unit 312.

[0041] In the inner casing of the display window 314, a symbol changing section 316 configured with three main monthly linoles 350A, 350B, and 350C as the main casing is disposed.

[0042] Also, at the bottom of the display window 314, a 7-segment display 315A for displaying the number of medals that are the game media of the pachislot machine 300, setting of the remaining number of jack games and the game state (six levels) display, etc. A display unit 315B for displaying the number of credits and a 7-segment display unit 3 15C for displaying the number of credits are provided.

[0043] The operation unit 306 has an upper portion protruding forward, and a medal insertion portion 320 is provided at the right end of the upper surface of the protruding portion, and credits are paid out in order from the left end of the upper surface. A checkout button 103, a single bet (insert) button 352A, and a pine bet (maximum input) button 352B are provided. 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 for receiving a medal discharged from the medal discharge port 326. [0045] The three reels 350A, 350B, and 350C are rotated so that the symbols can sequentially see the display window 314 force. The direction of rotation appears to move from the top to the bottom of symbol 1 in display window 314.

[0046] Here, among the symbols that can be seen from the display window 314 when the rotation is stopped, the line connecting the centers of the symbols arranged in the middle row, the line connecting the centers of the symbols arranged in the upper row, and the symbols arranged in the lower row The combination of the symbols that stop on the five active lines of the line that connects the centers and the two lines that connect the centers of the symbols that are lined up on two diagonal lines, respectively, indicates the result of the game.

[0047] Of the five lines, which line is the effective line is determined by the number of medals invested. When one medal is bet, the center of the symbols arranged in the middle line is connected. A line is considered an active line, and if 3 medals are bet, all lines are considered active lines.

[0048] The stop buttons 356A, 356B, and 356C are provided at the bottom of the symbol changing portion 316, and each of the linolees 350A, 350B, and 350C [correspondingly! In other words, the rotation of the corresponding reels 350A, 350B, and 350C can be stopped by the player operating the stop buttons 356A, 356B, and 356C.

[0049] 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 usually such that the three reels 350A, 350B, and 350C start rotating simultaneously.

[0050] Further, the operation timing by the start lever 354 is an internal lottery timing which will be described later, and the winning (winning) Z is determined by the operation of the start lever 354.

[0051] Of the above 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.

[0052] The reels 350A, 350B, and 350C do not stop between the symbols, and the stop is always controlled by the symbol pitch!

[0053] Further, in detail, the center line of the first symbol currently on the reference line exceeds the reference line. If there is a stop operation at that time, the linole 350A, 350B, 350C cannot be reversed, so until the center line of the next second symbol coincides with the reference line immediately after it is exceeded. The control to stop the second symbol (less than the maximum symbol pitch) is the so-called bitter stop criterion.

[0054] (Control system)

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

[0055] The control system of the pachislot machine 300 is mainly composed of a main control unit 100. The main control unit 100 identifies medals inserted from the medal insertion unit 320, and determines the number and types of medals inserted. Is connected to the medal selector 102 that outputs the type (illegal or genuine), etc., and the stop button 356A, 356B, 356C, MAX bet button 352B, 1 corresponding to each of the start lever 354 and the reels 350A, 350B, 350C described above The bet button 352A and a settlement button 103 for returning medals stored (credited) inside the gaming machine when the game is stopped are connected to each other via a sensor or the like (not shown) that detects the operation state.

[0056] Further, the main control unit 100 includes a main control circuit 110 including a CPU. The main control circuit 110 mainly includes a RAM 128 that temporarily stores a game progress status and the like, A ROM 130 in which various programs are stored 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 noise input via the frequency divider 126 to generate a random number sequentially. In the random number sampling circuit 122, the random number generator 120 Acquire and sample the generated random number.

[0058] In the pachislot machine 300, an internal lottery is performed by the main control unit 100 to determine whether a major player or a small player is successful at the operation timing of the start lever 354. In the main control circuit 110, the start lever When 354 is operated, random number acquisition circuit 122 is instructed to acquire, sample, and output random numbers, and thereby a lottery result is derived according to the random number input from random number sampling circuit 122. [0059] If the internal lottery is a win (role winning), the player will get the number of medals according to each symbol when the winning symbols are obtained by the stop operation with the stop button 356A, 356B, 356C thereafter In addition to this, a gaming state that is advantageous to the player can be made according to the arranged symbols.

Here, there are a small role and a big role as roles. Of these, the big actors include big bonuses (hereinafter referred to as “BB” where appropriate) and regular bonuses (hereinafter referred to as “RB” where appropriate), and the degree of advantage to the player differs in the corresponding games. . 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) The number of medals earned does not exceed the upper limit! It is configured to include RB games that can be won multiple times within the range! For this reason, naturally, 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.

[0061] Further, a motor drive circuit 132 is connected to the main controller 100, and each of the left (L), middle (C), and right (R) reel motors 106A is connected to the motor drive circuit 132. , 106B and 106C are connected to the left, middle and right linole 350A, 350B and 350C respectively.

[0062] Further, a reel position detection circuit 134 for detecting the rotational positions of the three reels 350A, 350B, 350C is connected to the main control unit 100. In the main control unit 100, each reel 350A , 350B, 350C can be known at any time.

[0063] 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 Start driving the reel motors 106A, 106B, 106C via the motor drive circuit 132 and rotate the three reels 350A, 350B, 350C, respectively. Then, the stop buttons 356A, 356B, 356C Based on the operation, the three reels 350A, 350B, and 350C are stopped.

[0064] Here, in the main control unit 100, when the rotation of the reels 350A, 350B, 350C is stopped based on the stop operation by the stop buttons 356A, 356B, 356C, the predetermined number of frames is determined according to the result of the internal lottery. The slip control is executed.

[0065] In other words, when the internal lottery is off, if the stop button 356A, 356B, 356C is operated at the stop timing when the symbol that stops only on the winning line stops on the active line, Therefore, in order to avoid the stop at this symbol, the stop position is shifted (kicked), and control is performed to stop at the off symbol array.

[0066] 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. The stop position is shifted (retracted) so as to

[0067] By kicking and pulling in, the result of the internal lottery and the result of the game can be made uniform, and even if the stop operation timing is slightly shifted, the winning symbols can be aligned. In this way, the player can be prevented from being lost as much as possible.

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

[0069] In addition, the reels that have already stopped (generally, the left reel 350A is stopped when the middle reel 350B is stopped, and the left reel 350A and the middle reel 350B are stopped when the right reel 350C is stopped. The amount of slippage also varies depending on the state of the symbols (upper, middle, lower).

Therefore, in the main control circuit, the stop operation timing by the stop buttons 356A, 356B, and 356C for each of the internal lottery results and the determined symbol rows (of the symbols to be bittered to the reference line described above). A slip control table (in this embodiment, a bit data table) that associates (specific) and the number of slip frames is stored, and the corresponding slip control table is determined based on the result of the internal lottery and the confirmed symbol sequence. Is read and slip control is executed.

[0071] Further, among the already stopped symbol arrangements, there is a case where the symbol power that has been won in the internal lottery may be able to win in a plurality of winning lines. In order to average the probability of winning a prize line, a point for setting a priority is assigned to the slip amount information read out from the slip control table used for the slip control. The slip control table and the point addition control will be described later.

In addition, a hopper drive circuit 136 for operating a hopper 138 provided inside the pachislot machine 300 is connected to the main control unit 100. The hopper 138 stores medals, and the main controller 100 specifies the medal based on the output from the reel position detection circuit 134. In accordance with the stopped pattern, medals are paid out from the hopper 138 via the hopper drive circuit 136.

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 the 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. Input to 100.

In main controller 100, when a payout completion signal is input from payout completion signal circuit 142, the medal payout by hopper 138 is terminated via hopper drive circuit 136.

[0075] Further, a display lamp driving circuit 144 is connected to the main control unit 100, and the 7-segment display unit 315A, the display unit 315B, and the 7-segment display unit 315C described above are connected via the display lamp driving circuit 144. In addition, it controls the turning on and off of the indicator lamp 146 such as the enabling line.

On the other hand, a sub control unit 150 is connected to the main control unit 100, and the main control unit 100 inputs a command signal indicating a control state to the sub control unit 150 as needed. In the present embodiment, as communication between the main control unit 100 and the sub control unit 150, only one-way communication from the main control unit 100 to the sub control unit 150 is executed. Communication with the control unit 100 cannot be performed at all.

A liquid crystal control circuit 152 is connected to the sub-control unit 150, and the liquid crystal control circuit 152 controls the display state of a liquid crystal display device (LCD) 313 provided for production.

In addition, a lamp driving circuit 156 is connected to the sub-control unit 150, and the decorative lamp 304A [incorporated! /, The lamp 112, and the linole 350A, 3 are connected via the lamp driving circuit 156. Emission is controlled by the backlight 158, etc., which is provided on the inner side of the 50B and 350C and emits light toward the positions facing the symbols on the peripheral surfaces of the linole 350A, 350B and 350C displayed on the display window 314.

[0079] Further, a speaker drive circuit 154 is connected to the sub-control unit 150, and the speakers 305L, 3

Stored. As the gaming state of the pachislot machine 300, for example, normal game, during BB internal selection, during RB internal selection, normal game during BB operation, during RB internal selection during BB operation, RB game, and the like can be mentioned.

[0086] In the table selection unit 182, the current gaming state (in general gaming state) from the gaming state control unit 186

, During the RT game, when the major role flag is established, during the major role (BB, RB), etc.), the role 'symbol is determined from the symbol's symbol table provided for each gaming state. Select.

[0087] Based on the role / symbol table selected by the table selection unit 182, the winning role's symbol determination unit 184 includes a winning role (small role (including replay), major role (RB, BB)) and winning symbol. And 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 is mainly configured by the game execution control unit 186A to play a game letter from the game program memory 188. The game state is controlled by appropriately reading and executing game program data corresponding to the state.

Note that the game program memory 188 stores data indicating a normal game program and data indicating a major player game program. For example, in the normal game state, the game program memory 188 stores the normal game program data. In the case of a major player gaming state, the major player game program data is read according to the internal winning state of BB and RB, and the gaming state of BB and RB, and processed based on the respective program data Is executed.

On the other hand, the main control unit 100 includes a reel drive control unit 194. Based on the start operation of the start lever 354, 4.1 seconds have elapsed after the end of the previous game, The reel motors 106A, 106B, and 106C are driven via the motor driving unit 132 to start the rotation of the reels 350A, 35OB, 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.

[0092] The reels 350A, 350B, and 350C are provided with detection sensors 198A, 198B, and 198C, respectively, and are connected to the reel drive control unit 194 via the reel position detection circuit 134. ! / At the time of the Linore Horse Ward U Utaki, the rotation positions of the Linore 350A, 350B, and 350C are recognized, and the reels 350, 350, and 350C are stopped while taking the above slip control into account. Then, the symbol arrangement of the stopped reels 350A, 350B, and 350C is sent to the game state control unit 186.

[0093] 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 the player has won any combination, and if a small combination is won, a predetermined payout is made. If the winning combination is a rebray, replay control is executed. If the winning combination is a major player, the major player game program is read from the game program memory 188 and executed by the game execution control unit 186A.

[0094] In addition, the regular bonus game program and the big bonus game program power are separately stored in the major player program, and are selectively read based on the elected major player. [0095] In the regular bonus program, a maximum of 12 games (maximum number of games) can be executed in a state where the lottery probability of a small role is higher than the probability of lottery during a normal game. The regular bonus game ends when a player wins a small role up to 8 times (maximum number of winnings) during these 12 games.

[0096] On the other hand, in the big bonus program, a regular bonus game can be executed with a high probability as an exercise of the right, and if the number of acquisitions in the big bonus game reaches a preset upper limit number, the regular bonus game is being executed. If so, the big bonus game is over. In this embodiment, the winning probability of the small role in the big bonus game is almost the same as that of the normal game.

[0097] Further, a flag memory 192 is connected to the gaming state control unit 186 via a 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 determined by the state of the flag. Manage.

[0098] Each flag is established by winning by internal lottery. Generally, the state of the small role flag disappears in one game (the flag is not established) (the winning state is invalid), but the flag state of the major role After that, each reel 350A, 350B, 350C is 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 a stop button 356A, 356B, 356C by the reel drive control unit 194. This is applied as a parameter for the slip control of pull-in or kick-off during stop control based on the operation of.

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

[0101] Stop buttons 356A, 356B, and 356C are connected to reference line design determining section 200. In the reference line symbol determination unit 200, when the stop button 356A, 356B, 356C (each) is operated, the symbol position is recognized by a signal from the reel position detection circuit 134, and so-called bittering is stopped. The design of is specified. The reference line is the upper line.

[0102] Information on the identified bittering stop symbol 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 includes a plurality of bit data tables 208 (X) (x = 1 2 ··· a-1 a) set for each gaming state (internal lottery result), and a plurality of slip commands. The number table 208 (y) (y = l 2 1 b) is stored (ab is a positive integer).

That is, in the slip control table memory 208, as the first reel stop control, the slip frame number table 208 (y) in which the number of slip commas is stored, and the reel stop control for the second and subsequent times. In addition, a bit data table 208 (X) in which bit data is assigned to each frame is stored in a mixed manner.

The table reading unit 206 selects and reads out the corresponding bit data table 208 (X) and sliding frame number table 208 (y) based on the determination result from the flag determination unit 204, and adds the points Send to arithmetic unit 201.

[0107] 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 (nm) and a template (for example, the left reel 350A has already stopped) In this state, the middle reel 350B is stopped, and a symbol that can be won) is added to the point addition (P), and the bit number determined by the stop operation timing of the stop button 356B or 356C. With the stop symbol as the 0th frame, the stop timing point calculation for adding the score (k) to each of the 0th frame, the 2nd frame, and the 4th frame is executed.

The point calculation result executed by the point calculation unit 201 is the slip control amount selection unit 20.

It will be sent to 2.

[0109] The slip control 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. As a result, the drive signal output unit 210 controls the motor drive circuit 132 to stop the reel motors 106A, 106B, 106C at a predetermined time.

[0110] The driving signal output unit 210 includes the gaming state control unit 186 (see Fig. 3) and a start. A lever 354 is connected to control the driving of the reel motors 106A, 106B, and 106C during the start control of the reels 350A, 350B, and 350C.

[0111] With reference to FIG. 6, the flow of the point addition process will be described with reference to the above basic point calculation, point addition point, and stop timing point, taking the case where the middle reel 350B is stopped as an example. Note that FIG. 6 shows the correlation in Tables 2 to 5 shown below, which is the same as Tables 2 to 5 described above.

[0112] (A) in Table 2 is a sliding frame number table 208 (y) read from the sliding control table 208 by the table reading unit 206 as the first reel stop control when “BELL” is selected. This shows the stop symbol arrangement of the left reel when a stop operation is performed at any of the positions 9, 10 and 11. As shown in (B) of Table 2, the upper row is “Red 7” and the middle row is “Watermelon”, the bottom row shows that it stopped at “Bell”. Therefore, it can be seen that there are two types of “Bell” winning lines: a descending line and a diagonal line that goes up to the right.

[0113] That is, the numerical value in the column of the number of sliding frames shown in (A) of Table 2 indicates that sliding is performed by the number of frames corresponding to the numerical value. For example, if an operation is performed when the symbol No. in which the value in the number of sliding frames is “3” is positioned at the top, the sliding control is performed for 3 frames from this point and stops. The same applies to the other numerical values (“1”, “2”, “4”), and the numerical value “0” indicates so-called bittering.

[0114] [Table 2]

When the stop operation is performed when any of symbols (9), 10, 10 and 1 in Table 2 is in the upper position. Position Left reel stop symbol

Upper red

Middle tier watermelon

Lower bell

[0115] When the symbol is stopped on the left reel 350A, the middle reel 350B reads bit data not shown in Table 3.

[0116] Based on this bit data, the bit data "0" has a score of n as a basic addition point.

+ 1 is assigned, and bit data “1” is assigned +4 as the point m.

[0117] This basic score is added so that the bit data "1" score will not be exceeded even if the stop timing score described later (+2 points as k points) is added to the bit data "0". It is.

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

[0119] In Table 3, the tempering points (points P) are executed for all bit data "1", but the bit data "1" is intentionally set where no tempering is performed. There is a case. This is a technique used to select the outcome in the case of missing, and no bit points are given to the bit data “1” for which such a setting has been made because there is no temper. [0120] When the calculation of the above 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. That's true.

[0121] [Table 3]

[0122] Table 4 shows the stop timing addition state for the tops within the slip control range for each of the 21 symbols assigned to the middle reel 350B.

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

[0124] As a result of the above points, a 5-frame figure determined by all stop operation timings of the middle reel 350B Among the 7572 patterns, +14 points is the highest score,

[0125] [Table 4]

[0126] In the slip control, as seen from the lower end of the column (bita stop position), the design with the first highest score is stopped, and the results are shown in Table 5. .

[0127] In Table 5, the upper, middle and lower stop symbols of the middle reel 350B are expressed by the numbers shown in Table 3, and the position (middle or lower) where the "bell" is tempered is found. In Table 5, the stop at the middle is indicated as “middle”, and the stop at the lower is indicated as “lower”.

[0128] As shown in Table 5, the ratio between the middle and lower stages of the “bell” stop position is 10:11, and it can be seen that it stops at any rate with a probability of approximately 1Z2.

[0129] In other words, the priority order for each symbol in the slip control is determined by the basic points, the tempering points, and the stop timing points, and the bias of the winning line due to a single bit data is avoided. Become.

[0131] The operation of the present embodiment will be described below.

First, the flow of normal games will be described.

[0133] The power to complete the betting of the medals by operating the single bet button 352A or the max bet button 352B in the state where the medal is credited (or the medal is inserted from the medal insertion unit 320), Alternatively, when a bet is completed by inserting a medal from the medal insertion unit 320, the start lever 354 can be operated.

[0134] When the start lever 354 is operated, the internal lottery force S is played by the lottery unit 180 simultaneously with this operation, and at the same time, the linole 350A, 350B 350C starts rotating.

The result of the internal lottery is transmitted from the winning combination / symbol determination unit 1848 to the gaming state control unit 186. The gaming state control unit 186 updates and stores the state of the flag in the flag memory 192 according to the result of the internal lottery via the flag management control unit 190.

[0136] After that, when the player operates the stop buttons 356A, 356B, 356C, the force to stop the rotation of the reels 350A, 350B, 350C by the stop operation is performed according to the flag stored in the flag memory 192. In consideration of this, stop control of the reels 350A, 350B, and 350C is executed so that the corresponding symbol is drawn into a 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 flag state stored in the flag memory 192 and the game state by the game state control unit 186, and the flag is established. In some cases, the winning symbol can be stopped by a precise timing. In addition, a slight shift in the stop operation timing is corrected by slip control. On the other hand, if the flag is not established, the reels 350A, 350B, and 350C will slip even if they are pushed, so that they do not stop at the winning symbol.

[0137] Next, when all reels 350A, 350B, and 350C are stopped, a prize is awarded based on the stopped symbols. A winning determination is made as to whether or not the power is correct. When winning a prize, the winning combination is also judged.

[0138] If it is determined by this determination that the major player has won, the bonus game control of the big bonus (BB) or regular bonus (RB) is executed (exercise) according to the stop pattern, When it is determined, predetermined payout control preset for the small combination is executed.

[0139] Here, when the stop operation by the stop buttons 356A, 356B, 356C is executed in sequence, the power of the linole 350A, 350B, 350C is stopped one after another! If the result of the internal lottery confirmed before that is winning and the symbol corresponding to the winning role is stopped at any of the symbols (upper or lower) of the left reel 350A, There is a possibility of winning on the winning line. For example, if the bell, which is a small role, is elected internally and this bell stops at the bottom of the left reel 350A, it can be aligned with the winning line on the down line or the diagonal line on the right-up diagonal.

[0140] 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 bit data by lottery is used. Although the ratio of the chances of winning a prize was 1: 1, the amount of memory consumed for one role was increased because of the need for multiple bit data.

[0141] On the other hand, in the present embodiment, a single bit data is allocated to one role, thereby reducing the amount of memory, and the bit data code allocation state and the subsequent stop operation. (Addition of stop operation with stop button 356B of middle reel 350B) etc., point calculation processing is executed for each symbol to be stopped. By considering the correlation between the points added, it is possible to make the winning percentages for multiple winning lines equal (1: 1 for two types of winning lines).

Hereinafter, the point calculation processing routine will be described with reference to the flowchart of FIG.

[0143] This flowchart describes the process from the stop of the left reel 350A to the stop of the middle reel 350B, and Tables 2 to 5 are based on the flowchart of FIG.

[0144] In step 250, it is determined whether or not the left reel 350A has stopped, and a negative determination is made. If so, the routine ends. If an affirmative determination is made in step 250, the process proceeds to step 252 to determine the stop symbol (upper, middle, lower) of the left reel 350A. For example, as shown in Table 2 (B), it is determined that “Red 7”, “Watermelon”, and “Bell” have stopped at the upper, middle, and lower stages, respectively.

[0145] In the next step 254, based on the result of the internal lottery and the stop symbol arrangement of the left reel 350A, bit data for stopping the middle reel 350B with slip control is read (see Table 3), Proceed to step 260.

[0146] In step 260, first, basic point addition processing is executed.

[0147] In the basic point addition process, n points (+1 points here) are added to the read bit data “0”, and m points (+4 points here) are added to the bit data “1”. To highlight.

[0148] In the next step 262, the Tempica saddle point process is executed.

[0149] For the tempering process, the winning line that is formed between the symbol of the left reel 350A and the symbol of the left reel 350C can be won by stopping the middle reel 350B. P points (here +8 points) are added.

[0150] After such basic addition and tempering addition, if there is a stop operation by stop button 356B of middle reel 350B (affirmative determination in step 264), the process proceeds to step 266 and stop timing addition processing is performed. Execute.

[0151] In the stop timing addition process, the design within the slip control range (5 frames in total) is identified based on the bitter stop design at the stop timing (see Table 4). Add k points (here, +2 points) to the 4th frame.

[0152] 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.

[0153] In the next step 268, slip control is executed so that the symbol having the highest score is stopped at the upper stage of the middle reel 350B, and this routine is terminated.

[0154] By specifying the stop symbols by scoring as described above, at each stop timing of 21 symbols as shown in Table 5, the “bell” is stopped at the middle or lower level. If you stop at the middle stage, the diagonal line that goes up to the right is the winning line, and if you stop at the lower stage, the down line is the winning line. [0155] Looking at the winning probabilities (assigned ratios) of these two types of winning lines, there are 10 patterns on the diagonal to the right and 11 patterns on the descending line, and either winning line is selected at approximately 1: 1. It will be. In other words, it is possible to select a pay line that has no bias.

[0156] As described above, in the present embodiment, even if a single winning combination can be won with two or more winning lines, the memory amount can be reduced by using a single bit data. Consumption can be reduced.

[0157] In addition, it is necessary to execute a point addition process (basic point addition, tenno point addition, stop timing addition) for each stop pattern for the bias of the winning line by applying a single bit data. With this, it is possible to set a score difference for each symbol and stop the desired symbol at the desired position (upper, middle, lower, or kick), avoiding a bias in the winning line, and with almost equal probability. Can be realized.

[0158] In other words, by prioritizing each symbol in slip control by adding basic points, tempering points, and stop timing points, the "bell" has traditionally been placed on two types of winning lines (middle and lower). In order to stop at almost the same rate, it was necessary to prepare two types of bit data. On the other hand, it is possible to perform stop control in an equivalent state with a single bit data.

In this embodiment, the force described for the stop control of the middle reel 350B when the left reel 350A stops first. The stop of the right reel 350C when the left reel 350A and the middle reel 350B stop first. It can also be applied to control.

Industrial applicability

[0160] It can be used for a gaming machine such as a slot machine that uses medals, coins, game balls, etc. as a game medium. In particular, in a pachislot machine, in the reel stop control, only the binary bit data for the slip amount is used. By memorizing, the memory capacity is reduced, and the same stop control nourishment as when the conventional number of sliding frames is memorized is maintained.
