Abstract

PROBLEM TO BE SOLVED: To achieve a higher function of a hold game in which game is conducted by moving and displaying arbitrary symbol trains alone. SOLUTION: Symbol display windows 5 are arranged in a matrix of 3×3 and a CRT display is made on a display surface 3. Symbol trains are moved and displayed in each of the symbol display windows 5 and judgment of winning is performed when the moving and displaying actions is stopped. A front panel 10 is provided with a selection operating part 9 having nine section buttons in a 3×5 array corresponding to the array of the symbol display windows 5. The selection buttons are selected and operated as desired. But, in the subsequent hold game, the moving and displaying of the symbol trains are forbidden on the symbol display windows though corresponding thereto. When the prize is won in the vertical prize line set on the left symbol display windows in the first slot machine game, at this moment, the taking up of dividend scores is retained and while the position is held up, the subsequent hold game can be started.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a slot machine, and more particularly, to a slot machine having a symbol holding function.

[0002]

2. Description of the Related Art A slot machine having a hold function is known from Japanese Patent Application Laid-Open No. 63-5777. For example, in a three-reel slot machine having a hold function, after playing the game for the first time and stopping three reels, one or two reels to be held are to be held before playing the next game. select. When the reels are started in the next game, two or one reel other than the selected one is rotated, and when these reels stop, it is determined whether or not there is a winning.

In such a slot machine with a hold function, the presence or absence of a prize is determined by a combination of a symbol intentionally left by a player and a symbol of a reel that has been newly rotated and stopped. Can be reflected. In particular, since it is difficult to obtain a prize in which a large payout is likely to be obtained, when a reel constituting such a prize is displayed and the reel is stopped, the reel is held and the next game is started. As a result, the probability of occurrence of a high payout prize can be increased, and a great sense of expectation can be given to the player.

[0004]

However, in the conventional slot machines, little attention has been paid to the hold function when a prize is obtained in the first game.
That is, when the rotation of the reels is stopped, a small portion winning can be obtained simply by stopping one or two specific symbols on a predetermined winning line, and in this case, coins are immediately provided. Payout (used as terms including medals and tokens) is executed. Therefore, if the reels are held so as not to lose the small prize prize and the next game can be executed, the small prize can be continuously obtained in the next game, and the payout of the payout coins is performed again. Is performed.

In order to avoid such an unnatural game form, the payout of payout coins is suspended when a prize is won, and when the next game is performed using the hold function, reels are not used in the next game. It is also possible to adopt a configuration in which the winning determination is performed again at the stage when the rotation is stopped and the payout coin is paid out. However, if this configuration is adopted, the number of reels that can be rotated in the next game is restricted, for example, in order to secure a small win, and it is extremely difficult to aim for a large win with many payout coins, or In order to aim for the big win in the next game, there were drawbacks, such as having to abandon the small win in the first game.

The present invention has been made in consideration of the above-mentioned prior art, and ensures that winnings obtained in the first game can be saved, but various winnings in the next game using the hold function. An object of the present invention is to provide a slot machine capable of aiming at a slot machine.

[0007]

SUMMARY OF THE INVENTION According to the present invention, most of the conventional slot machines display two or three symbols on one reel from a single display window. Focusing on the fact that two or three symbols are carried over to the next game as they are, which greatly limits the types of winning in the next game. Are arranged in the form of a square matrix of 3 rows and 3 columns or more so that the symbol columns are moved and displayed for each of the symbol display windows, and the player can select whether or not to hold for each of these symbol display windows. It is like that.

For example, when the symbol display windows are arranged in three rows and three columns, in order to prohibit the movement display of the symbol column at an arbitrary position in the next game, for example, 9
Although nine selection buttons are required, arranging these nine selection buttons in three rows and three columns in correspondence with the arrangement of the symbol display windows is effective in preventing erroneous operations. The display window selecting means is configured so that its operation is validated even when a prize is obtained, as well as when it is lost in the first game, and the hold function can be utilized in the next game. Then, when the next game is performed using the hold function after the winning symbol combination is obtained,
Granting of a bonus (for example, payout of a payout coin) for the winning is suspended, and awarding is performed according to the result of the winning determination in the next game.

In addition to the slot machine in which the reels are actually driven by using a stepping motor, there is also a video-type slot machine in which symbol images are displayed in a moving manner on a CRT monitor so that a symbol row is moved and displayed. However, the present invention is equally applicable to any type of slot machine. Furthermore, the present invention may be applied to a slot machine incorporated as a secondary game machine in a game machine such as a pachinko machine to enhance the interest of the game.

[0010]

FIG. 1 shows a video type slot machine using the present invention. The game console 2 has a CRT
And its display surface 3 is exposed on the front panel. Various screens are displayed on the display surface 3 in accordance with the progress of the game. When a normal slot machine game is played, a frame line 6a that divides the symbol display window 5 in three rows and three columns and a frame line 6b that divides a display field for displaying a message such as the next operation to the player are shown in FIG. Fixedly displayed.

In each of the symbol display windows 5, a symbol row is individually moved and displayed, and a plurality of types of symbols are displayed in one symbol display window 5 so as to flow sequentially from top to bottom. . To move and display such a symbol row, graphic data of symbols is stored in a memory prepared for each symbol display window 5 in the display order, and these are sequentially read out and supplied to a CRT drive circuit. Good. Similarly, for message display, message data is stored in memory for each content,
What is necessary is just to read out an appropriate one from a predetermined address in accordance with the progress of the game and supply it to the CRT drive circuit.

A design panel 7 is fitted above the front panel, and the name of the slot machine and the like are drawn together with the design pattern, and are brightly displayed by an illumination lamp or the like incorporated behind the design panel. In addition, as described later in detail, in this slot machine, in addition to a normal slot machine game, a game in a special mode of a double-up game, a hold game, and a fever game can be executed. Which of the games is being executed is also known from the display of the design panel 7. Note that the design panel 7 may display a combination of winning symbols and a bonus given to the player by each winning, that is, a payout score (corresponding to the number of coins paid).

Since the symbol display windows 5 are arranged in three rows and three columns, three horizontal pay lines are formed by combining three of the symbol display windows 5 horizontally, and three vertical lines are formed by combining three vertically and vertically.
A total of eight pay lines, including two pay lines and two pay lines that are diagonally combined, are determined in advance. Prior to the start of the game, when a bet of 1 to 8 points out of the acquired scores accumulated and stored in the credit counter is made, a prize is referred to at the time of winning determination according to the bet score. The number of lines is determined. The same applies to the case where 1 to 8 coins are inserted from the coin insertion slot 8 and a bet is made.

The operation panel 10 on the front side of the front panel includes:
Various operation buttons that are appropriately operated by the player in accordance with the progress of the game are provided. The following operation buttons are provided from the upper left of the operation panel 10 toward the right end.

[0015]

[Table 1]

FIG. 2 shows the types of symbols used in this slot machine. There are three types of bell symbols, "gold bell", "silver bell", and "bronze bell" according to their colors. Also, there are three types of rolled board symbols, "3 rolled boards", "2 rolled boards", and "1 rolled board", depending on the number of them, and other "coins", "cherry",
There are nine types of symbols including "8".

These nine types of symbols are converted into graphic data, respectively, and stored in nine symbol data memories provided for each symbol display window 5. The arrangement order differs for each symbol data memory. Further, in order to change the probability of occurrence for each winning combination, it is preferable that the number of symbols stored in one symbol data memory is set to 9 or more by using appropriate symbols redundantly.

There are the following winning combinations in a normal slot machine game. Line winning prize ・ Three identical symbols are aligned on one prize line ・ Three bell symbols are aligned on one prize line ・ Three bar symbols are aligned on one prize line ・ One prize line One or two cherry symbols are awarded. All wins ・ Nine identical symbols are available on all symbol display windows ・ Only bell symbols are available on all symbol display windows ・ Only rolled board symbols are available on all symbol display windows -Only coin symbols and rolled board symbols are aligned in all symbol display windows.-Two to eight symbols appear in all symbol display windows. Corner winning role-Four identical symbols are displayed in the symbol display windows at the four corners. Align

Furthermore, as a result of playing a normal slot machine game, if any one of five bell symbols is arranged in a cross in nine symbol display windows 5, a fever prize is won, and the fever game can be executed. The fever game can be played seven times in a row, and each time a score bet is made. However, the upper limit of the score that can be betted at this time is the bet score in the game when the fever winning is obtained.

In the fever game, the symbol display window 5
After moving and displaying the symbol columns for all of the above, when these are stopped, a winning determination is made, and it is determined whether there is a bonus winning combination in addition to the line winning combination and the all winning combination described above. In the bonus winning combination, the payout score is determined based on how many bell symbols of the same type appear when the fever is won. For example, when the mode is shifted to the fever mode with a gold bell, the bet score × α (= 5)
X The number of displayed gold bells is the dividend score for the bonus winning combination. When a fever is won with a silver bell and a bronze bell, the bet score and α
(3 for silver bell: 1 for bronze bell) is the dividend score of each bonus winning combination.

FIG. 3 schematically shows an electrical configuration of a slot machine using the present invention. When the operation button group 12 provided on the operation panel 10 is operated, the operation input detection circuit 13 inputs the operation signal to the CPU 15. CPU
15 is a program ROM for operating the slot machine.
In accordance with the game program stored in the game program 16, an operation signal input unrelated to the progress of the game is invalidated. The coin sensor 17 is provided at the back of the coin insertion slot 8, and inputs a coin detection signal to the CPU 15 every time when detecting proper insertion of a coin.

The working RAM 18 is a primary storage location for various flags and data used in the course of executing the game program, and the CPU 15 writes and reads data at appropriate timing. The working RAM 18 includes, for example, a credit counter area for accumulating a payout score obtained every time a game is won, a storage area for a bet score input every time the game starts,
A storage area for a flag indicating that the symbol array is being moved or displayed in the symbol display window 5 or the symbol displayed in each symbol display window 5 when the movement of the symbol column is stopped. And an area for storing position data of a symbol display window selected and held by the player when shifting to the hold game.

The winning pattern / payout table 20 is a ROM
In addition to the line winning combination, the all winning combination, and the corner winning combination in the above-described normal slot machine game, the combination data of the symbols constituting the winning combination in the fever mode is stored, and each of the winning combinations is stored. The payout score data for the combination is stored. The winning pattern / payout table 20 is accessed by the CPU 15 when the moving display of the symbol row is stopped.
It is used to determine whether the combination of symbols stopped and displayed in the symbol display window 5 corresponds to a winning, and to read a payout score for each winning.

In addition to the above data, the winning pattern / payout table 20 also stores graphic data for displaying a combination of symbols constituting a winning combination and a payout score for each winning combination. These graphic data are read out by the CPU 15 when the player operates the odds button and displayed on the display surface 3. When the pay button is operated, the coin payout device 21 pays out to the tray 11 the number of coins corresponding to the payout score accumulated by the credit counter.

CRT 24 incorporated in game machine body 2
A CRT drive circuit 25, a symbol data memory 26, a card data memory 27, a message data memory 28, and a frame pattern memory 29 are used to display various screens according to the progress of the game on the display surface 3.
The frame pattern data memory 29 stores frame line pattern data for displaying the frame lines 6a and 6b, and is constantly read out by the CPU 15 in the normal slot machine game processing process, and is displayed on the display surface 3 of the CRT 24. Will be displayed.

The symbol data memory 26 has nine divided memory areas corresponding to the nine symbol display windows 5. In each of the memory areas, a plurality of symbol data in which the symbols of various symbols shown in FIG. 2 are represented by graphic data for each dot are stored in random order, and as a result, these memory areas are stored in the symbol row holding means. It has become. In each memory area, the C address is designated by the designation of the start address assigned to each symbol.
The data is read out one line at a time in synchronization with the horizontal synchronization signal of the RT 24. Of course, the memory area from which graphic data is read is switched for each symbol display window 5 partitioned by the frame line 6a.

The card data memory 27 stores the back surface pattern of the playing card and one set of picture patterns as graphic data. These data are used in a double-up game described later. The message data memory 28 stores message data for displaying various messages according to the progress of the game. By designating the head address of each message data, the corresponding message is displayed in the frame 6b.

The hold function characteristic of the present invention will be described with reference to FIG. In the first normal slot machine game played, if the symbol display of FIG. 4A is obtained in the symbol display window 5 when all eight pay lines are valid, a coin symbol is displayed on the left vertical pay line. A line prize will be awarded because there are three of them. Also, since there is one cherry symbol on the lower horizontal winning line, the line is also awarded here. Therefore, when the take score button is operated at this point, the coin symbol 3
A total of "82", a predetermined payout score of "80" for a line winning in a row and a predetermined payout score of "2" for a line winning of one cherry symbol, is added to the credit.

However, since coin symbols are also displayed in the central symbol display window 5, if these coin symbols are held as they are in the next game, for example, as shown in FIG. Even if a coin symbol comes somewhere in the vertical line on the right side, two line prizes with three coin symbols are obtained. In such a case, even if the payout is lost by pressing one take symbol button while the take score button is pressed in the state of FIG. It is more advantageous to hold the coin symbol as it is for the display window 5 and play the next game. In addition, since the line winning with three coin symbols is held as it is in the next game, even if no coin symbol appears on any of the right vertical lines in the next game, the payout score “80” can be obtained as it is. It is possible.

FIG. 5 shows another example of the hold. When the first game result is in the state of FIG. 5A, a line winning in which three gold bell symbols are arranged in the center horizontal line is obtained, and a predetermined payout score “30” is obtained. In the lower horizontal line, a predetermined payout score “2” is obtained by winning one cherry symbol line.
However, since two gold bell symbols are also present on the vertical line in the center, if the gold bell symbol comes also in the lower center, a fever prize is won.

Therefore, instead of holding the gold bell symbol marked X in FIG. 5A and abandoning the line winning of one cherry symbol, it is possible to aim for the fever winning in the next game. Then, when the pattern of FIG. 5B is obtained, a fever prize is won. In a fever game that can be executed after a fever prize is won, a bonus prize is also valid in addition to a line prize and an all prize, so the game is played with a much higher prize probability than a normal slot machine game. . In addition, since the fever game can be played seven times in a row, the payout score obtained thereby is almost always larger than the line winning with three gold bell symbols. Even if the player does not win a fever, a line winning with three gold bell symbols can be secured, so that the above selection is advantageous for the player.

As described above, during the execution of the hold game, the moving display of the symbol row is prohibited in the symbol display window at the position where the player has selected the hold with the selection button, and the moving display of the symbol row is prohibited only in the other symbol display windows. Done. As described in detail later, such selective movement of the symbol row is displayed by the CPU 15 shown in FIG.
This is performed by the display control means including the working RAM 18 and the symbol data memory 26. The hold game cannot be played twice in succession.

FIG. 6 shows a display screen of the double-up game. The double-up game is a game selected by a player when a prize is obtained in a normal slot machine game or a fever game and the player aims to double the payout score obtained in the prize by directly betting.
When the double-up game button is operated after some kind of winning has been obtained, the display screen of the CRT 24 is cleared, and then the back of the playing card is displayed as shown in FIG. Number is "1-6"
Or “8 to 13”.

When the player predicts that the value falls within the range of "1 to 6", he or she presses the small selection button on the operation panel 10, and
When the prediction is "8-13", the large selection button is pressed.
Waiting for this selection input, the CPU 15 reads out the picture data from the card data memory 27 and performs the display of FIG. When the player's prediction is correct, the player obtains twice the bet score, and loses the bet score when the player loses his bet score. If the number of the picture is "7", the event is even. This double-up game can be repeated continuously, and when quitting, press the take score button to settle.

The card data memory 27 stores the picture data of one set of playing cards, and the picture is selected by the CPU 15 calling the head address of each. The selection of the picture is performed at random by using a random number generator incorporated in the CPU 15.

Next, the operation of the slot machine will be described with reference to the flowcharts shown in FIGS. Prior to the start of a regular slot machine game,
First, a bet score input operation is required. For the input operation of the bet score, coins may be actually inserted from the coin insertion slot 8, but all exchanged coins are once inserted from the coin insertion slot 8 and stored in the credit counter,
Thereafter, the bet button may be operated to input a bet score from among the credits.

The bet score can be arbitrarily determined by the player in the range of “1 to 8”. The number of winning lines activated at the time of winning determination is determined in accordance with the bet score. For a line winning combination, the presence or absence of a winning is determined only on the activated winning line. That is, the symbol display window 5 which is valid at the time of winning determination according to the bet score
Is determined. To check the type of winning combination and the payout score, the odds button is operated before the start button is operated. CPU
15 fetches the display data stored in the winning pattern / payout table 20 and displays it on the CRT 24.

After inputting the bet score, moving the display of the symbol array is started by operating the start button, and the symbols are displayed in each symbol display window 5 so as to move from top to bottom. The moving display of this symbol row is performed by sequentially displaying graphic data for symbol display from nine memory areas in the symbol data memory 26 into C.
This is performed by supplying to the RT drive circuit 25. At this time, by driving the CRT 24 while adjusting the read timing of the graphic data,
The moving speed of the symbol array can be gradually changed from a low speed to a high speed, and from a high speed to a low speed, and a pseudo rotation of the reel can be displayed.

By pressing any one of the stop buttons, the movement display of the symbol row is stopped. When one stop button is pressed, the moving display of the symbol rows stops all at once for all the symbol display windows 5, and when the other stop button is pressed, the moving display of the symbol rows stops for each symbol display window in a predetermined order. I do. If the stop button has not been operated after a certain period of time, the movement of the symbol array automatically stops in a predetermined order.

When the movement display of all the symbol columns is stopped, the working RAM 18 stores a symbol code representing the type of the symbol stopped and displayed for each symbol display window 5.
Is written to a predetermined area. Symbol data memory 2
The arrangement order of the symbols stored in each of the memory areas 6 is known in advance together with the head address of the graphic data.
, The type of symbol can be specified based on the start address of the symbol data memory designated by the CPU 15 when the movement display of the symbol row is stopped,
A symbol code corresponding to this can be obtained.

It is possible to identify which symbol is currently displayed in each symbol display window and what the next symbol is to be displayed even during the moving display of the symbol row. If it is within the range where the timing does not shift extremely from the time the button was operated,
It is possible to perform the stop control of the symbol row so that the symbols determined by the CPU 15 by software appear. By performing such stop control, it is possible to adjust the probability of winning, so that it is possible to adjust the payout rate while monitoring the game results that have been consumed, for example.

After the symbol array is stopped, a winning determination is subsequently made. In determining a winning, a symbol code stored in a predetermined area of the working RAM 18 for each symbol display window, a winning line activated according to a bet score, and a symbol stored in the winning pattern / payout table 20 are determined. CPU15 is the combination pattern
Contrasted by If no winning combination is obtained as a result of the winning determination, the game enters a hold game start input standby state.

In this input standby state, if there is an input from the hold operation section 9 (see FIG. 1) composed of nine selection buttons and the same bet score as the first game is inputted, the game shifts to the hold game. . After the first game is over, if a new start button is pressed or a predetermined time has elapsed, the game machine enters a standby state for the next normal slot machine game and returns to the start in FIG.

If any winnings are obtained in the first slot machine game, the process shifts to the next game selecting process shown in FIG. In the selection processing of the next game, first, a payout score corresponding to the obtained winning is displayed in the frame 6b as a message, and when the take score button is operated, the payout score is taken into the credit at that time and the processing is terminated. Before operating the take score button, either the double up game or the hold game can be selected.

When the double-up game is selected, FIG.
The double-up game process shown in FIG. The double-up game is a game that aims to double the payout score obtained immediately before as a bet score as it is. When the double-up game starts, the display surface 3 of the CRT 24
6 (a) is displayed, and the player predicts whether the number of the picture of the playing card is in the range of "1 to 6" or "8 to 13". ,
If "1-6", "Small selection button" is changed to "8-13"
If so, press the "large selection button".

When this operation input is performed, the CPU 15 displays the picture of the playing card as shown in FIG. 6 (b), compares the picture number with the player's large / small selection input, and displays the picture of the player. Win / Loss judgment is performed based on the appropriateness of the selection input. When the player wins the double-up game, twice the bet score becomes the payout score at that time. As long as the payout score is not added to the credit by operating the take score button, the double up game can be used as the bet score as it is at that time, and can be repeated as many times as necessary until the player loses. If the picture on the playing card is "7", a draw is made.

The double-up game is not necessarily limited to the above-mentioned game mode. Even if a playing card is used, for example, it may be predicted whether the mark is a set of “heart and diamond” or a set of “spade and club”. In addition, even if the size is selected, after the selection input, a screen display for rolling the dice may be displayed to determine whether the prediction is appropriate. In addition, various types of games, such as a rock-paper-scissors game, a roulette game, and a mahjong game, may be combined instead of the double-up game. Such a modification can be implemented in the program ROM 1
6 can be easily handled by rewriting the double-up game program stored in the predetermined address area.

If a winning is obtained in the first slot machine game, a hold game can be selected instead of the double up game. For this purpose, the symbol display window may be selected and input from the hold operation unit 9 without operating the double-up game button, and the same score bet as in the previous game may be performed. When a predetermined time has elapsed without selecting any of the double-up game and the hold game, or when the take score button is operated, the payout score is added to the credit and the processing is terminated.

When the game shifts to the hold game in the state where the pattern of FIG. 4A has been obtained, the player selects one of the three vertically long symbols on the left side of the symbol display window from the hold operation section 9. This selection data is written to the working RAM 18. When the start button is operated after the same bet score input as in the previous game is performed, the CPU 15 reads out the selection data held in the working RAM 18 and, based on this, sequentially designates the head address for reading out graphic data in the symbol data memory. To start moving and displaying the symbol row at the back of the symbol display window for which hold is not designated. Thereafter, the winning determination is performed after all the movement display of the symbol array is stopped.

It should be noted that the bet score input for performing the hold game can be automatically performed. Since the working RAM 18 stores the bet score at the time of the start of the previous game, the score may be subtracted from the credit when the selection data is input from the hold operation unit 9 to input the bet. At this time, when the credit is insufficient, a coin insertion request is displayed in the message box.

As described above, the hold operation unit 9
Is composed of nine selection buttons arranged in three rows and three columns corresponding to the arrangement of the symbol display windows 5. Each selection button is associated with the symbol display window 5 according to the arrangement, thereby preventing erroneous operation. It is planned. A light emitting device such as a light emitting diode is incorporated in each of the selection buttons, and all light up when a state in which the game can be shifted to the hold game is achieved.
Then, when the player checks the symbol displayed on the symbol display window 5 and presses a selection button at a position corresponding to the symbol to be held, the light emitter at that position turns off, and the next hold game is performed. Indicates that the symbol row is not moved.

The configuration of the hold operation section 9 is not limited to the selection buttons arranged in a matrix corresponding to the symbol display window as described above, and may be of any arrangement. Further, for example, a transparent touch switch is provided at each position of the symbol display window 5 displayed on the display surface 3 of the CRT 24 to form a hold operation unit, and a player touches a symbol to be held with a fingertip. Is detected and the selected data is read. In this case, it is preferable that a part of the frame line 6a or the symbol itself be displayed brightly in correspondence with the selected symbol display window, and the player confirm and display which symbol display window is selected.

Further, a selection lever or a button in the form of a cursor key is provided on the front panel 10 to change the color and brightness of a part of the frame line 6a or the stopped and displayed symbol itself by these operations. , The symbol display window may be selected and displayed. Further, the movement display or the movement stop of the symbol row at the start of the hold game is performed in one of the columns or rows.
You may make it perform for every column.

As a result of the holding game, FIG.
If the movement of the symbol row is stopped in the state of, the diagonal prize line is also activated according to the bet score. Three line winning combinations are obtained. In addition, if the all winning combination is obtained,
Instead of the line winning combination, the score payout is based on the all winning combination.

When the above-mentioned hold game is played, the previous line winning combination is stored as it is, so that even if no additional winning is obtained in the hold game, the payout score is obtained for the previous line winning combination. Can be. However, the added bet score is lost. As for the hold game after the winning in the first slot machine game, the payout score is directly incorporated in the credits as shown in FIG. 10 and the game ends, but when the fever winning in the hold game is obtained, It is possible to shift to a fever game.

FIG. 9 shows a hold game process when no winning is obtained in the first slot machine game. In this case, after the same processing is performed up to the winning determination in the hold game processing shown in FIG. 10, the double-up game can be selected on condition that a payout score is obtained by some kind of winning. Become. Of course, if a fever prize is generated, the right of the fever game is obtained, and the payout score can be directly taken into the credit by operating the take score button to end the process.

The Fever prize is a special prize in the line prize combination, and the Fever game can be played seven times with the bonus prize added as described above. During this fever game, if a normal line winning combination or an all winning combination is obtained, the payout score can of course be obtained. If the take score button is operated, the payout score is directly added to the credit and one fever The game ends. It is also possible to select a double-up game by operating the double-up game button instead of operating the take score button, and operate the hold operation unit 9 to execute one hold game per fever game. It is also possible to do.

The embodiment of the present invention has been described with reference to the accompanying drawings. However, in practicing the present invention, the modes of the double-up game and the fever game are not limited to those described above, and may be appropriately discarded. May be. Also,
Instead of displaying the game screen on the CRT 24, a liquid crystal display panel can be used. Further, the present invention can be applied to a mechanical reel type slot machine in which reels are arranged at the back of each of the symbol display windows 5, and a double-up game function can be added by combining a small CRT or a liquid crystal display panel. Can be.

In addition, the types and arrangements of the various operation buttons arranged on the front panel can be appropriately set and changed, and the number of symbol display windows, the types of symbols constituting the symbol columns, and the number of symbols per symbol column can be changed. The number of arranged symbols, the types of winning combinations and payout scores, the odds, the values of bet scores, the direction of moving and displaying the symbol row, the stopping method, the stopping order, and the like are various without departing from the scope of the present invention. It is possible to change to the form.

[0060]

As described above, according to the slot machine of the present invention, the symbol display windows are arranged in a square matrix of 3 rows and 3 columns or more, and the symbol columns are independently provided for each symbol display window. In the next game, the movement of the symbol array is prohibited and held for each symbol display window during the next game, so that the winnings obtained in the first game can be saved and Hold game can be executed. In addition, when a plurality of selection buttons operated when performing the hold selection for each symbol display window are arranged in accordance with the arrangement pattern of the symbol display windows, it is possible to prevent an erroneous operation when performing the hold selection input operation. It is effective.
