Description

[0001]
[Industrial application fields]
This invention Three symbol display units that can move and display symbol rows are provided, and each symbol display portion starts moving display of symbol rows in response to a player's starting operation, and then the player stops each moving display in sequence. Depending on the operation Stop and Predetermined stop across each symbol display Victory or defeat is now decided by the combination of symbols stopped on the line Slot machine About.
[0002]
[Prior art]
A typical conventional slot machine is configured by arranging three reels behind a symbol display window. On the outer peripheral surface of each reel, a symbol row composed of a plurality of types of symbols is represented. The reels are simultaneously rotated by the game start operation by the player, and are displayed in a state where the symbol row of each reel is moved in the symbol display window.
[0003]
Five stop lines, upper, middle, lower, and diagonal, are drawn at the formation position of the symbol display window so as to cover each reel. Under the state where the movement display of the symbol row is performed, if the player performs the stop operation of each reel in sequence, the movement display of the corresponding reel is stopped, and each of the three symbols on each stop line is stopped. Are displayed in an aligned state. When a combination of specific symbols is established on the activated stop line at this time, a prize is awarded, and a privilege such as paying out a predetermined number of medals is given to the player.
[0004]
In this type of slot machine, whether or not to establish a combination of winning symbols on the activated line by lottery in the control unit inside the aircraft at the stage where the player has started the game operation. When the winning is established, the control unit performs so-called pull-in control in which a symbol for winning is drawn and stopped on a predetermined line with respect to the corresponding reel at each stop operation by the player. carry out.
[0005]
By this control, when the first and second reels are stopped and only the last reel is rotating, a winning symbol combination is established on a predetermined line, which is called “tempe” (or “reach”). When a possible state occurs, the player increases his expectation for winning and concentrates on the final reel stop operation.
[0006]
Further, in recent years, when such a possibility of winning has occurred, a notification means such as a voice or a display lamp is operated to notify the player that there is a possibility that winning will be established. It has been proposed to increase expectation (Japanese Patent Laid-Open No. 9-103539).
[0007]
[Problems to be solved by the invention]
However, in this type of slot machine, the probability that a winning symbol combination is actually established is limited to a predetermined numerical range, and even if a temper is established by stopping all reels except the final reel, The symbol combinations that are finally established are shifted at a considerable rate. Therefore, for a player who has continued the game for a long time or is familiar with the contents of the game, the establishment of a simple temper and the notification thereof have no important meaning, and there is a problem that the player's expectation cannot be sufficiently increased.
[0008]
The present invention has been made paying attention to the above-mentioned problems, and makes the player feel that there is a high possibility that a specific winning will be established, thereby increasing the expectation for winning and not disappointing that expectation. like Slot machine The technical challenge is to provide
[0009]
[Means for Solving the Problems]
In order to solve the above-described problem, in the present invention, the symbol column can be moved and displayed, and three symbol display portions for stopping and displaying three symbols when the moving display is stopped are arranged in a horizontal row, Three stop lines along the horizontal direction and two stop lines along the diagonal direction are set so as to connect the symbol stop display positions for each symbol display portion, and it is determined whether or not a winning is achieved. The lottery means for carrying out the lottery, the start control means for starting the movement display of the symbol row on each symbol display unit in response to the player's start operation, and the movement display on each symbol display part in turn for the player's stop operation And stop by the lottery Special prize with transition to bonus game When the winning symbol for the winning is drawn into one of the stop lines in which the winning symbol is made valid, the control for stopping the movement display of each symbol display section is performed. In a slot machine having stop control means that executes the control with the number of frames limited to a predetermined number of frames, each symbol display unit has a stop when the movement display of the two symbol display units is stopped. Of the special prize Symbol combination Two of the three symbols that make up are aligned on the same stop line Tempe state But, Simultaneously on 2 or 3 stop lines Established Like Of two adjacent symbol displays Each symbol column Two special winning symbols arranged side by side Is done. Further, when the stop control means has decided to establish a specific prize by the lottery, Special prize In order to establish the tempering state on more stop lines, the number of draw-in frames for the first and second stop-operated symbol display portions is set. Within the above limit number of frames Configured to adjust.
[0011]
Further, the stop control means In the lottery Special prize When you are off The number of stop lines where the TEMPE state is established at the same time may be three. The number of frames to be drawn in for the second stop operation is adjusted so that the second stop operation does not occur.
[0012]
[Action]
In this invention, By lottery Special prize When it is decided to establish the symbol line, when stopping the symbol string movement display for the first and second stop operations, the number of stop lines is increased. Depending on special winning symbol Adjust the number of draw-ins so that the tempering state is established. Therefore, when the number of established lines in the tempered state is two or three, a specific winning is actually established with a high probability.
[0013]
In addition, we lost the special prize in the lottery in case of, The number of stop lines where the TEMPE state is established simultaneously does not become three Therefore, if the number of established lines in the TEMPE state becomes 3, As long as the stop operation is performed at the position where the special winning symbol exists within the limited number of draw-in control in the symbol display section to be finally stopped, it is possible to always establish a specific winning. .
[0014]
【Example】
FIG. 1 shows the appearance of a slot machine to which the present invention is applied, and FIG. 2 shows the internal structure of the machine body.
The machine body 1 of this slot machine is configured such that a door portion 3 is attached to a front opening of a box-shaped main body portion 2 so as to be opened and closed. The hollow portion of the main body 2 incorporates a reel block 4 and a circuit board 5 on which a control circuit and the like are installed at an upper position, and a medal discharge having a hopper 6a that accommodates a large number of medals at a lower position. Machine 6 etc. are incorporated.
[0015]
The reel block 4 is formed by integrally assembling three reels 8a, 8b and 8c to a metal frame 7. On the outer peripheral surface of each reel 8a, 8b, 8c, in addition to “7”, which is a specific symbol related to the bonus game, symbols of a plurality of types are arranged in a predetermined order, and some of the symbol symbols Constitutes a symbol for establishing a prize.
Further, the reel block 4 is assembled with stepping motors 9a, 9b, 9c for individually rotating the reels 8a, 8b, 8c.
[0016]
As shown in FIG. 3, each reel 8a, 8b, 8c is provided with a reference signal generator 43 for generating a reference signal described later. The reference signal generating device 43 of the illustrated example includes a protrusion 41 integrally formed on a shaft portion 40 that connects between the outer peripheral frame of each reel 8a, 8b, 8c and a central boss portion, and a position where the protrusion 41 passes. It is comprised with the photoelectric sensor 42 arrange | positioned. A reference signal is generated from the photoelectric sensor 42 every time the projection 41 blocks the optical path of the photoelectric sensor 42 due to the rotation of the reel, and is supplied to the counting unit 53 of the CPU 31 described later.
[0017]
The main body of the door portion 3 is constituted by a metal frame having a predetermined thickness, and three panels 11, 12, 13 are provided in the front opening, and a wiring board (not shown) for various displays and operation switches on the rear surface. )) Is assembled.
[0018]
Each panel 11, 12, 13 is formed by performing silk screen printing on the surface of a transparent synthetic resin plate or tempered glass, and there is no coloration at the position corresponding to each reel of the central front panel 11. Thus, transparent symbol display windows 20a, 20b, and 20c are formed. Also, model names, game information, and the like are drawn on the upper panel 12 and the lower panel 13.
[0019]
In the frame portion between the front panel 11 and the lower panel 13, a start lever 14, stop button switches 15a, 15b, 15c, bet button switches 23, 24, a medal slot 16, and the like are arranged below the lower panel 13. Are provided with a medal payout outlet 17, a medal tray 18, a speaker 22, and the like. A lighting device 21 is attached above the upper panel 12.
[0020]
As shown in FIG. 4, the symbol display windows 20a, 20b, and 20c on the front panel 11 are formed at a total position of upper, middle, lower, and diagonal so as to cross the symbol display windows 20a, 20b, and 20c. Five stop lines L1 to L5 are shown. When the reels are stopped, the symbols of the reels 8a, 8b, and 8c are aligned on the stop lines L1 to L5, respectively.
An illumination device 19 made of a fluorescent lamp is disposed inside the front panel 11. After the power is turned on, the lighting device 19 is always turned on, and the outer peripheral surfaces of the reels 8a, 8b, 8c are illuminated obliquely from above.
[0021]
In this embodiment, symbol rows are moved and displayed by mechanical reels 8a, 8b, and 8c. However, instead of these reels 8a, 8b, and 8c, a rotating body such as a belt or a disk is used. It is also possible to move and display the symbol string by using it. Further, the symbols may be displayed in a variable manner by displaying the symbols as images on the display screen of the liquid crystal display panel or CRT display and scrolling.
[0022]
The slot machine of this embodiment can implement a so-called credit-type game in which a large number of medals are stored in the body and the game is executed by consuming the stored medals. A state in which the game can be started is set by the consumption of the stored medals by inserting medals or by pressing the bet button switches 23 and 24. If the number of inserted medals is one at this time, if only the central stop line L1 is two, the upper, middle, and lower three stop lines L1 to L3 are three. The upper, middle, lower, and diagonal five stop lines L1 to L5 are each activated.
[0023]
In the slot machine configured as described above, a predetermined number of stop lines are activated by the player's medal insertion operation (meaning either the above-described medal insertion or the operation of the bet button switches 23 and 24), and then the start lever 14 When all the reels 8a, 8b, and 8c are started at the same time by the above operation, a lottery process is performed in the control circuit unit 28 described later, and it is determined whether or not to display the winning symbol combinations on the active line. . When this lottery is “winning”, the control circuit 28 thereafter stops the winning symbol on the active line for the corresponding reels 8a, 8b, 8c each time the stop button switches 15a, 15b, 15c are operated. The pay-in control is executed and a winning is established (however, this is not the case when a winning symbol is not positioned within the predetermined limit number at the time of the stop operation).
[0024]
When all reels 8a, 8b, and 8c are stopped, a predetermined number of medals are paid out when the same kind of winning symbols are displayed in alignment on the active line. The number of medals to be paid out is individually set according to each winning symbol. When the special winning symbols “7”, “7”, and “7” are displayed in a line, a “bonus that allows a large amount of medals to be obtained” Move to “Game”.
[0025]
In the slot machine of this embodiment, at least one place on each reel 8a, 8b, 8c, and various winning symbols so that a case where two or more winning symbols are simultaneously displayed in the same symbol display window occurs. Are arranged alternately or continuously. As a result, as shown in FIG. 5, when two reels are stopped and only the last reel is rotating, it is possible to simultaneously establish a temper on two or three lines. It becomes.
[0026]
In each example of FIG. 5, all the stop lines L1 to L5 are activated, and the reels 8a, 8b, and 8c are stopped in the order of left, center, and right, and the left and center reels 8a, 8b are stopped. Indicates the time when the line stops, and only the line where the tempering is established among the lines L1 to L5 is represented by a solid line. Each symbol in the figure is set as a winning symbol.
[0027]
As a state in which a tempering is established on two lines (hereinafter, this state is referred to as a “double tempering”), as shown in FIGS. As shown in 5 (3) and (4), there are two cases where a template with the same symbol is established for each line. Similarly, even if a tempering is established on three lines (hereinafter this state is referred to as “triple tempering”), as shown in FIG. As shown in FIGS. 5 (6) and (7), there are cases where a template with the same symbol is formed on two or three lines.
[0028]
The illuminating device 21 has a built-in lamp that emits two different types of colored light such as red and yellow. In this embodiment, when a tempering is established on a plurality of lines, for example, when a “double tempering” is established, illumination with yellow light is performed, and when a “triple tempering” is established, illumination with red light is performed. In response to this, the lamp to be lit is switched to notify the establishment of each template. The sound circuit 39 to be described later has a unique sound effect for each of the triple tempe and the double temper, and in conjunction with the operation of the lighting device 21, the sound effect according to the number of established tempes is obtained from the speaker 22. Is output.
[0029]
Assuming that the reels 8a, 8b, and 8c are stopped at the position corresponding to the player's stop operation without using the pull-in control, the higher the number of lines where the temper is established, the higher the probability that a winning will be established. You can expect.
[0030]
Further, in this embodiment, when it is determined in the lottery process that a special winning with the symbol “7” or a general winning with the symbol symbol is established, the reels 8a, 8b and 8c are placed on more lines. The stop operation of each of the reels 8a, 8b, and 8c is controlled so that the triple temper is not established when the temper is established and the lottery is lost.
As a result, when the triple temper and the double temper are established, a winning is actually established with a high probability, not just an appearance. In particular, when a triple temper is established, it is possible to establish a special prize as long as a stop operation is performed at a position where a winning symbol exists within the limit number of the above-mentioned pull-in control on the reel to be finally stopped. .
[0031]
Therefore, when a triple tempe or double tempe that guarantees a high winning probability appears, the player expects to win more than a temper only on a single line (hereinafter referred to as “single tempe”). With a sense of consciousness, attention is paid to the stopping operation of each reel 8a, 8b, 8c. In addition, since the lighting of the lighting device 21 and the sound from the speaker 22 are notified of the establishment of the double tempe or the triple tempering, even if the player misses the establishment of the tempering, it can be noticed by the above notification. You can increase your expectation for a special prize. Furthermore, by notifying different forms according to the number of established temperaes, it is possible to cause the player to correctly recognize the number of established tempies, and to effectively produce each tempered to increase the player's euphoria.
[0032]
In addition, paying attention to the symbol display position relating to the establishment of the winning in the reel (reel 8c in the illustrated example) that is finally stopped for each tempering formation line, Of FIG. (1) (3) (4) (5) (7) as in the case where different symbol display positions are set for each line, Of FIG. (2) As shown in (6), a common symbol display position may be set for a plurality of lines. Therefore, for each aspect of each temper, which symbol of the reel to be finally stopped and which symbol display position is noticed vary, and an interesting game can be developed.
[0033]
The lighting device 21 may be set not only above the upper panel 12 but also on the front panel 12. Moreover, it replaces with this kind of illuminating device 21, and a character indicator may be arrange | positioned and the message according to the form of the established temper may be displayed. In addition, a large number of point light sources such as LEDs are arranged at the symbol display positions of the symbol display windows 20a, 20b, and 20c to identify and display symbols related to the template, and display lamps are provided beside the stop lines L1 to L5. Various means can be set for notifying the possibility of winning, such as arranging and displaying the line where the temper is established or notifying the speaker 22 by voice data.
[0034]
FIG. 6 shows an electrical configuration of the slot machine.
In the figure, a control circuit unit 28 is composed of a microcomputer, and includes a CPU 30 that is a control subject, a program, a ROM 31 that stores fixed data such as a lottery reference table, a symbol arrangement table for each reel, and the like. It includes a RAM 32 used, a random number generator 33 for lottery processing, and the like.
[0035]
The control circuit unit 28 is connected to the start lever 14, the stop button switches 15a, 15b, and 15c, the bet button switches 23 and 24, the medal sensor 34, and the photoelectric sensor 42 (see FIG. In the following description, each input part such as 42a, 42b, 42c for each reel), two types of light sources 35, 36 for the illumination device 21, a light source 37 for the illumination device 19, a medal dispenser 6, Respective output units such as the reel driving units 38a, 38b, 38c and the audio circuit 39 for each reel are connected.
[0036]
The medal sensor 34 is disposed inside the medal slot 16 and detects the insertion of medals into the machine body. The reel driving units 38a, 38b, and 38c drive the stepping motors 9a, 9b, and 9c of the reels 8a, 8b, and 8c, respectively, to rotate and stop the reels 8a, 8b, and 8c.
[0037]
FIG. 7 is a functional block diagram showing a part of the functions of the CPU 30. Although only the circuit configuration for the first reel 8a is shown in the drawing, the same configuration is set for the center and right reels 8b and 8c.
[0038]
In FIG. 7, the medal detection signal from the medal sensor 34 and the operation signals from the bet button switches 23 and 24 are given to the effective line setting unit 51, and 5 Stop line L1 L5 A line corresponding to the number of medals inserted is set to be effective.
[0039]
The reel drive unit 38a receives the clock signal, generates a drive pulse P, supplies the drive pulse P to the stepping motor 9a, and drives the reel 8a. A start command and a stop command are given to the reel drive unit 38a from the control unit 52 of the CPU 30.
[0040]
When the start lever 14 is operated, a start signal is input to the control unit 52, and in response to this, the control unit 52 issues a start command to the reel drive unit 38a to operate the stepping motor 9a. Thereafter, when the stop button switch 15a is pressed and a stop operation signal is input to the control unit 52, the control unit 52 issues a stop command to the reel drive unit 38a to stop the operation of the stepping motor 9a.
[0041]
During this time, the drive pulse P is given to the counting unit 53 of the CPU 30 and counted. The count value K by the counting unit 53 is reset by a reference signal supplied from the photoelectric sensor 42a of the reference signal generator 43 every time the reel 8a makes one rotation. This count value K is for representing the current rotation angle position of the reel, in other words, a symbol located at a predetermined reference position in the symbol display window 20a.
[0042]
As the reference position, for example, the lower symbol stop position in the reel display window 20a, that is, the position of the stop line L3 is set. The symbol detection unit 54 refers to the symbol arrangement table in the ROM 31 based on the count value K, detects which symbol on the reel 8a is located on each line, and determines the detection result as a determination unit 45 and a control unit. Output to 42.
[0043]
The determination unit 55 is also provided with a symbol detection result from the symbol detection unit for the other reels 8b and 8c. When all the three reels 8a, 8b and 8c are stopped, the winning symbol is obtained. It is determined whether or not the combination is established. The determination unit 55 is given the setting result by the effective line setting unit 51, and the above determination processing is performed for all the activated lines.
[0044]
The lottery unit 56 performs lottery using random numbers when the start lever 14 is operated and the reels 8a to 8c start to rotate, and determines a symbol combination to be established on the active line. When a stop operation signal is input from the stop button switch 15a, the control unit 52 stops the symbols determined by the lottery on the active line as much as possible based on the detection result by the symbol detection unit 54 at that time. Such symbol pull-in control is performed.
[0045]
8 to 10 show the flow of control of the slot machine by the control circuit unit 28. FIG. In the figure, “ST” indicates each step of control.
In ST1, when a game start operation is performed by the player, that is, when a medal is inserted and the start lever 14 is operated, the CPU 30 rotates all the reels 8a, 8b, and 8c at the same time, and whether the hit flag is set. Check whether or not (ST2, 3).
[0046]
The winning flag is set when it is determined that the special winning is achieved by the lottery process, and the flag once set is effectively carried over until the special winning is achieved. If there is no carryover of this flag, the CPU 30 performs a lottery in the next ST4 as to whether or not to arrange a combination of symbols for special winning or general winning on the active line. Specifically, the lottery is performed by sampling the random value generated by the random number generator 33 and comparing the sampled value with a reference table in the ROM 31. The lottery becomes a “big hit”. If it is decided to establish a special prize, the next ST5 is “YES”, and the winning flag is set in the subsequent ST6.
If the winning flag has been carried over from the previous game, the lottery process is skipped.
[0047]
All reels 8 a, 8 b, 8 When the player performs the first stop operation after starting c, ST7 becomes “YES”, and the CPU 30 checks the winning flag and the lottery result. If the winning flag is set, the process proceeds from ST8 to ST10, and the CPU 30 stops the reel that has been operated to stop by drawing the special winning “7” symbol onto a predetermined effective line. In addition, when it is determined that a winning with a predetermined symbol symbol is established by lottery, the process proceeds from ST9 to ST11, and reel stop control is performed so that the target symbol symbol is drawn on the active line. Is done.
[0048]
However, as described above, if these symbols to be pulled in do not exist within 4 frames from the reel rotation position at the time of stop, the corresponding reel moves by a predetermined number of frames within 4 frames according to the stop operation. However, at this time, a predetermined winning symbol may be drawn and stopped so as to establish a triple template or a double template with a general winning symbol.
When the lottery is off, ST8 and ST9 are both “NO”, and the reel is controlled to stop at a position corresponding to the stop operation in principle.
[0049]
Next, when there is a second stop operation, ST13 becomes “YES”, and the CPU 30 checks the lottery result again in next ST14. If it is determined that a special prize or any general prize is to be established, the CPU 30 further checks whether or not the pull-in control for establishing the temper is possible for the stopped reel. (ST15-17).
[0050]
If the stopped reels are pulled within 4 frames from the stop operation position, if three templates including the template corresponding to the target winning symbol can be established, ST15 becomes “YES”, and the CPU 30 Stops the reel after it has been pulled to a position where the triple template can be established (ST18).
[0051]
If it is determined in ST15 that it is impossible to establish a triple template, it is checked in ST16 whether a double template can be established. If this determination is “YES”, the process proceeds to ST19, and the reel that has been operated to stop is pulled to a position where a double template can be established and stopped.
[0052]
If neither the triple tempo nor the double tempering can be established, both ST15 and ST16 are “NO”, and it is checked in ST17 whether the single tempering with the target winning symbol can be established. If this determination is “YES”, the reel that has been operated to stop is pulled to a position where a single template can be established and stopped (ST20), but if the determination is “NO”, The pull-in control is not performed, and the reels are stopped according to the timing of the stop operation (ST21).
[0053]
On the other hand, if the winning flag is not set and the lottery result is “out of”, ST14 is “NO” and the process proceeds to ST22.
In ST22, the stopped reel is stopped at the timing when only a symbol completely unrelated to winning appears in the symbol display window, and at the predetermined probability, a double template or a single template with a winning symbol is established. Pull-in control is performed. However, when the stop operation is performed at a timing at which the triple tempering can be established, reel pull-in control is performed so that the triple tempering is not established.
[0054]
When the two reels are stopped and the triple template is established at that time, the process proceeds from ST23 to ST25, the red light source 35 of the illuminating device 21 is turned on, and the triple 22 for the triple template is turned on from the speaker 22. Sound effects are output. When the double temper is established, the process proceeds from ST24 to ST26, the yellow light source 36 of the lighting device 21 is turned on, and a sound effect for the double temper is output.
[0055]
Thereafter, when the final stop operation is performed, ST27 becomes “YES”, and the CPU 30 checks the hit flag again in the next ST28. If the flag is set, it is checked in ST29 whether the special winning symbol “7” can be drawn from the reel rotation position at the time of the stop operation, and when this determination is “YES”. When the reel pull-in control for establishing the special prize is “NO”, the reel stop control corresponding to the stop operation is performed (ST30, 33). After the special winning is established in ST30, the CPU 30 proceeds to a bonus game routine (not shown), executes a predetermined number of bonus games, returns to the normal control mode, and sets the winning flag. Reset (ST31, 32).
[0056]
If it is determined in ST28 that the winning flag is not set, the process proceeds to ST34, the lottery result is checked again, and if it is determined to establish a general winning, the combination of the winning symbols is selected. Pull-in control for establishment is performed (ST36). When the winning is established, a winning process such as paying out a predetermined number of medals is performed in the next ST37. However, if the corresponding winning symbol cannot be pulled in due to the movement of 4 frames, the process proceeds from ST35 to ST33, and reel stop control is performed so that the reel is “disconnected” in accordance with the stop operation.
[0057]
Also, if the determination of ST34 is “NO”, that is, if it is decided to leave this game in the lottery, ST38 Then, the pull-in control is performed so that no winning symbol combination is established on any active line. Therefore, even if a double template or a single template is established by the first and second reels, the pull-in control is performed so that the same winning symbol is removed from the line where the template is established. Become.
[0058]
In the above-described embodiment, the symbol combinations for various winnings are the same symbols arranged in an aligned manner. However, the present invention is not limited to this. And it is also possible to implement the control similar to the said Example about the combination.
[0059]
In this embodiment, when the reels 8a, 8b, and 8c are stopped, the symbol display windows 20a, 20b, and 20c are stopped for three symbols, respectively, and a maximum of five effective lines are set. However, the number of reels, the number of symbols to be stopped, and the number of lines are not limited to this. Each line is not limited to a line extending in one direction as in the embodiment, but may have a V-shaped refraction pattern.
In addition, according to such a change in configuration, it is possible to simultaneously establish a tempering on three or more lines.
[0060]
Furthermore, the double tempe and the triple tempe generated in the reel stop control of the present invention can be used as “reach eyes” for notifying the player that the special winning flag is set. Conventional reach eyes were difficult to confirm because they had complicated symbol combination patterns. However, such double templates and triple templates can be easily confirmed, and the player has a hit flag set. You can quickly recognize that you are.
[0062]
【The invention's effect】
As described above, in the present invention, by lottery Special with transition to bonus game If it is decided to win, the number of draw-in pieces for the symbol display part to be stopped first and second is set. Within the limit number of frames By adjusting, so that the TEMPE state is established on more stop lines Because we control If the number of lines in the tempering state is 2 or 3, it is not just an appearance but actually a high probability. Special prize Will be established. In particular, when a lottery shifts to a special prize, control is performed so that the number of established lines in the tempering state does not become three. Therefore, if a triple temper is established, the special prize will be established with a very high probability. The player ’s It is possible to produce a game result that does not disappoint.
Furthermore, according to the present invention, depending on the form of the established temper, the symbol display unit to be finally stopped is set to have only one symbol display position for establishing a winning or multiple cases for winning. , Can develop interesting games.
