Description

  The present invention relates to a gaming machine that displays symbols superimposed using two types of symbol arrays.

  In the gaming machine, the game result is determined by the symbols rearranged on the symbol display device. When a winning pattern is formed by the rearranged symbols, a payout according to the winning pattern is paid out.

  Since the payout is determined by the establishment of the winning pattern, the player shows high interest in the rearranged symbols. However, there is a limit to the winning patterns that can be achieved simply by scrolling the symbol sequence and rearranging the symbols. For this reason, there has been a gaming machine in which symbols to be rearranged are changed to easily establish a winning pattern.

  For example, there is a gaming machine that changes a normal symbol to a scatter symbol. The player selects a desired symbol in advance, and when the selected symbol is rearranged, information indicating that it is handled as a scatter symbol is displayed in a superimposed manner and processed as a scatter symbol. Even if the symbols selected by the player are not aligned on the payline, a payout is paid out if the winning pattern of the scatter symbol is established (see, for example, Patent Document 1).

  There is a gaming machine that changes to a wild symbol with a predetermined reel. When the player selects a desired reel in advance and a predetermined symbol is stopped on the selected reel, information indicating that it is treated as a wild symbol is displayed in an overlapping manner, and the symbol is processed as a wild symbol. If a winning pattern is established by replacing the wild symbol with another symbol, a payout corresponding to the winning pattern is paid out (see, for example, Patent Document 2).

US Patent Application Publication No. 2008/058088 US Patent Application Publication No. 2007/287529

  The above-described conventional gaming machine displays information indicating that it is handled as a scatter symbol and information indicating that it is handled as a wild symbol superimposed on the rearranged symbols. As described above, when the function of the symbol is changed, information indicating the change is superimposed and displayed.

  However, in these gaming machines, an operation for selecting a predetermined symbol by the player and an operation for selecting a reel by the player are required as a preliminary process for changing the symbols. As described above, since the player's operation independent of the lottery process is involved, it is difficult to adjust the payout only by the lottery process. For this reason, there is a possibility that the conventional gaming machine cannot sufficiently control the profit given to the player.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a gaming machine that can diversify a winning pattern and can control a profit given to a player.

The first embodiment of the present invention comprises:
A gaming machine having the following configuration,
By rearranging a plurality of types of symbols constituting the first type of symbol sequence and a plurality of types of symbols constituting a second type of symbol sequence different from the first type of symbol sequence, the game result is obtained. A symbol display device to display;
A controller that executes a game by scrolling the first type symbol row and the second type symbol row on the symbol display device;
The first type of symbol string is configured by arranging a plurality of symbols at a predetermined interval,
The second type symbol row is configured by arranging a plurality of symbols at the same interval as the predetermined interval,
The length of the first type symbol row in the scroll direction is different from the length of the second type symbol row in the scroll direction.
In the symbol display device, the controller overlaps the symbols of the first type of symbol sequence and the symbols of the second type of symbol sequence to form the first type of symbol sequence and the second type of symbol sequence. It is configured to scroll at the same speed.

  The plurality of symbols of the first type symbol sequence and the plurality of symbols of the second type symbol sequence are arranged at the same interval. What is the length of the first type symbol sequence and the length of the second type symbol sequence? Different. Furthermore, the first type symbol row is scrolled at the same speed as the second type symbol row.

  For this reason, the time for one round of the first type symbol sequence is different from the time for one cycle of the second type symbol sequence. That is, the period of the first type symbol string is different from the period of the second type symbol string. Therefore, the symbols of the second type of symbol sequence in which the symbols of the first type of symbol sequence overlap are gradually shifted with scrolling, and the pair of the symbol of the first type of symbol sequence and the symbol of the second type of symbol sequence becomes a pair. It changes with scrolling. Without the player's operation, the winning pattern based on the symbols of the first type of symbol sequence and the winning pattern based on the symbols of the second type of symbol sequence can be changed and established.

  Further, the plurality of symbols constituting the first type symbol string and the plurality of symbols constituting the second type symbol string are both arranged at the same predetermined interval. For this reason, even when the first type symbol row and the second type symbol row are being scrolled, the relative positional relationship between the paired symbols can be kept constant, and the overlapping state of the paired symbols is Therefore, it is possible to prevent the scroll symbol from being gradually shifted along with the scroll, and to visually recognize the symbol in the scroll state.

According to a second embodiment of the present invention, in the first embodiment of the present invention,
The controller executes a game in a base game mode, and executes a game in a feature game mode different from the base game mode,
The plurality of types of symbols constituting the first type of symbol string include a first symbol in which a winning pattern as a payout target is established,
The plurality of types of symbols constituting the second type of symbol sequence are configured to include a second symbol serving as a trigger for shifting from the base game mode to the feature game mode.

  The first type of symbol string includes a first symbol in which a winning pattern as a payout target is established. The second type symbol row includes a second symbol that shifts from the base game mode to the feature game mode. For this reason, while the winning pattern to be paid out is established by the first type of symbol sequence, the second type of symbol sequence can be used to shift to the feature game mode, so that different profits can be given redundantly.

According to a third embodiment of the present invention, in the first embodiment of the present invention,
The controller is
A first lottery process for determining symbols to be rearranged from a plurality of symbols of the first type of symbol sequence;
And a second lottery process for determining symbols to be rearranged from a plurality of symbols of the second type symbol string.

  The symbols of the first type of symbol sequence are determined by the first lottery process, and the symbols of the second type of symbol sequence are determined by the second lottery process. The winning probability based on the two types of symbol strings can be defined independently. For this reason, the payout by the first type symbol sequence and the payout by the second type symbol sequence can be determined separately, and the profit given to the player can be easily controlled.

A fourth embodiment of the present invention is the third embodiment of the present invention,
The controller is
(4-1) Processing for determining whether the time from the start of scrolling to rearrangement is longer than a predetermined time;
(4-2) When the time until the symbols determined by the first lottery process are rearranged is longer than the predetermined time, the position of the symbol determined by the first lottery process is scrolled. To reconstruct the first type symbol string by moving to a position downstream of
(4-3) When the time until the symbols determined by the second lottery process are rearranged is longer than the predetermined time, the position of the symbol determined by the second lottery process is scrolled. To reconstruct the second type symbol sequence by moving to a position downstream of
Is configured to run.

  When the time until rearrangement becomes long, the symbol is moved to a position downstream of the scroll, and the first type symbol column and the second type symbol column are reconfigured. Can be rearranged within the time. The time for each unit game can be made constant, and the value of the valuable facilities can be consumed at certain time intervals to ensure the profit of the gaming facility.

A fifth embodiment of the present invention is the fourth embodiment of the present invention,
The downstream position is configured to be a position from the display area toward the upstream of the scroll by a number smaller than the number of symbols displayed along the scroll direction of the display area of the symbol display device.

  Since the symbol is moved upstream by a number smaller than the number of symbols displayed along the scroll direction in the display area, the symbol is moved to a position closer to the symbol display device, and the symbol is immediately displayed on the symbol display device. Can appear.

  Diversify the winning patterns and control the profits given to players.

The gaming machine according to the present embodiment
A gaming machine (for example, a slot machine 10 described later) having the following configuration,
A plurality of types of symbols constituting a first type of symbol sequence (for example, a normal reel band 3n described later) and a second type of symbol sequence different from the first type of symbol sequence (for example, a jackpot described later) A symbol display device (for example, a lower display device 141 (lower liquid crystal display panel 141b) described later) or the like that displays a game result by rearranging a plurality of types of symbols constituting a reel band 3jp) )When,
A controller (for example, a main CPU 71 described later) that scrolls the first type symbol row and the second type symbol row on the symbol display device and executes a game;
The first type of symbol string is configured by arranging a plurality of symbols at a predetermined interval,
The second type symbol row is configured by arranging a plurality of symbols at the same interval as the predetermined interval,
The length of the first type symbol row in the scroll direction is different from the length of the second type symbol row in the scroll direction.
In the symbol display device, the controller overlaps the symbols of the first type of symbol sequence and the symbols of the second type of symbol sequence to form the first type of symbol sequence and the second type of symbol sequence. Scroll at the same speed.

  As shown in FIG. 1A, the gaming machine includes a symbol display device and a controller.

  The controller executes the game by scrolling the first type symbol row and the second type symbol row on the symbol display device.

  The first type symbol string is composed of a plurality of types of symbols. The second type symbol sequence is different from the first type symbol sequence. The second type symbol string is composed of a plurality of types of symbols. The symbols of the first type of symbol sequence and the symbols of the second type of symbol sequence may differ in some symbols and the remaining symbols may be the same.

  For example, the first type of symbol string shown in FIGS. 1A to 1B is composed of twelve symbols A to L. These twelve symbols are symbols for one period of the first type symbol string. The second type symbol string is composed of seven symbols, symbol 1 to symbol 7. These seven symbols are symbols for one period of the second type symbol string.

  The game result is displayed on the symbol display device by rearranging a plurality of types of symbols constituting the first type symbol row and a plurality of types of symbols constituting the second type symbol row.

  A plurality of symbols are arranged at a predetermined interval in the first type symbol row. Also in the second type symbol row, a plurality of symbols are arranged at the same interval as the predetermined interval. 1A and 1B, symbol A corresponds to symbol 1, symbol B corresponds to symbol 2, symbol C corresponds to symbol 3, and symbol D corresponds to symbol 4, symbol E corresponds to symbol 5, symbol F corresponds to symbol 6, and symbol G corresponds to symbol 7. As will be described later, the correspondence relationship between the symbols of the first type of symbol sequence and the symbols of the second type of symbol sequence changes gradually with scrolling.

  Further, the length of the first type symbol row in the scroll direction is different from the length of the second type symbol row in the scroll direction. For example, the number of symbols constituting the first type symbol row is different from the number of symbols constituting the second type symbol row. In the example shown in FIG. 1A and FIG. 1B, the first type symbol string consists of 12 symbols, the second type symbol string consists of 7 symbols, and the length of the first type symbol string is 2nd. It is longer than the length of the seed symbol string.

  The controller overlaps the first type symbol and the second type symbol and scrolls the first type symbol row and the second type symbol row at the same speed. In the example shown in FIG. 1A, the first type symbol row and the second type symbol row scroll at the same speed in the downward direction indicated by the arrow.

  As described above, the plurality of symbols of the first type of symbol sequence and the plurality of symbols of the second type of symbol sequence are arranged at the same interval, and the length of the first type of symbol sequence and the second type of symbol are arranged. It is different from the length of the column. Furthermore, the first type symbol row is scrolled at the same speed as the second type symbol row.

  For this reason, the time for one round of the first type symbol string is different from the time for one round of the second type symbol string. That is, the period of the first type symbol string is different from the period of the second type symbol string. Therefore, the symbols of the second type symbol sequence, where the symbols of the first type of symbol sequence overlap, gradually shift with scrolling.

  For example, as shown in FIG. 1C, in pair 1, symbol A of the first type symbol string overlaps symbol 1 of the second type of symbol string, and in pair 2, symbol A of the first type of symbol string is , And overlaps the symbol 6 of the second type symbol string. As described above, the symbol of the second type symbol row corresponding to the symbol A of the first type symbol row changes from the symbol 1 to the symbol 6 by scrolling. Note that the first type symbol column and the second type symbol column overlap and scroll, but in FIG. 1C, the first type symbol column and the second type symbol column are shown separately for the sake of clarity. It was.

  Both the first type symbol row and the second type symbol row scroll downward as indicated by arrows in FIG. 1C. As the first type symbol sequence and the second type symbol sequence scroll, the overlapping symbols gradually shift, and the first type symbol sequence and the second type symbol sequence are scrolled in the same direction at the same speed. Thus, overlapping symbol pairs can be changed.

  With this configuration, the winning pattern based on the symbols of the first type symbol sequence and the winning pattern based on the symbols of the second type symbol sequence are changed and overlapped without any player operation. Can be made.

  Further, the plurality of symbols constituting the first type symbol string and the plurality of symbols constituting the second type symbol string are both arranged at the same predetermined interval. For this reason, even when the first type symbol row and the second type symbol row are being scrolled, the relative positional relationship between the paired symbols can be kept constant, and the overlapping state of the paired symbols is Therefore, it is possible to prevent the scroll symbol from being gradually shifted along with the scroll, and to visually recognize the symbol in the scroll state.

further,
An input device (for example, a “BET × 1” button 34 to a “BET × 5” button 39, a “4 WAYS” button 40 to a “1024 WAYS” button 44, etc., which will be described later) is input. In addition,
The instruction regarding the game is a ratio to a payout or a bet size.
It is preferable that the number of symbols in the second type of symbol row is configured to increase as the rate for the payout and the bet size increase.

  When the game is started by increasing the magnification or BET, the player can visually recognize that the number of symbols in the second type symbol row is increasing even during scrolling, and can increase the expectation of the jackpot. In addition, the ease with which the jackpot winning pattern is established can be determined only by the configuration of the second type symbol string, and the profits given to the player can be controlled more precisely.

The gaming machine according to the present embodiment further includes
The controller executes a game in a base game mode (for example, a base game mode described later) and executes a game in a feature game mode (for example, a jackpot game mode described later) different from the base game mode. ,
The plurality of types of symbols constituting the first type of symbol string are the first symbols (for example, RED, PURPLE, GREEN, YELLOW, BLUE, ACE, KING, QUEEN, which will be described later) that are subject to a payout pattern. , JACK, TEN, NINE, etc.)
The plurality of types of symbols constituting the second type of symbol string include a second symbol (for example, JP) that triggers a transition from the base game mode to the feature game mode.

  The first type of symbol string includes a first symbol for which a winning pattern is established. When the winning pattern is established, a payout based on the winning pattern can be determined. The second type symbol row includes a second symbol that can be shifted from the base game mode to the feature game mode.

  For example, in the example shown in FIGS. 1A to 1D, the symbols A to L of the first type symbol string are the first symbols, and a winning pattern can be established. Symbols 1 and 4 with a ribbon mark of the second type symbol row are second symbols.

  While the winning pattern to be paid out is established by the first type of symbol sequence, it is possible to shift to the feature game mode by the second type of symbol sequence and to give different profits in duplicate.

The gaming machine according to the present embodiment further includes
The controller is
A first lottery process (for example, the process of steps S4411 to S4415 in FIG. 44 to be described later) for determining symbols to be rearranged from a plurality of symbols of the first type symbol row;
Second lottery processing (for example, processing in steps S4417 to S4421 in FIG. 44 to be described later) for determining symbols to be rearranged from a plurality of symbols of the second type symbol row is executed.

  The symbols of the first type of symbol sequence are determined by the first lottery process, and the symbols of the second type of symbol sequence are determined by the second lottery process. The winning probability based on the two types of symbol strings can be defined independently. For this reason, the payout by the first type symbol sequence and the payout by the second type symbol sequence can be determined separately, and the profit given to the player can be easily controlled.

The gaming machine according to the present embodiment further includes
The controller is
(4-1) Processing for determining whether the time from the start of scrolling to rearrangement is longer than a predetermined time (for example, processing in step S4513 or S4517 in FIG. 45 described later),
(4-2) When the time until the symbols determined by the first lottery process are rearranged is longer than the predetermined time, the position of the symbol determined by the first lottery process is scrolled. , A process of reconfiguring the first type symbol string by moving it to a downstream position (for example, a process in step S4515 in FIG. 45 described later),
(4-3) When the time until the symbols determined by the second lottery process are rearranged is longer than the predetermined time, the position of the symbol determined by the second lottery process is scrolled. , To reconstruct the second type symbol string (for example, the process in step S4519 in FIG. 45 described later),
Execute.

  When the time until rearrangement becomes long, the symbol is moved to a position downstream of the scroll, and the first type symbol column and the second type symbol column are reconfigured. Can be rearranged within the time. The time for each unit game can be made constant, and the value of the valuable facilities can be consumed at certain time intervals to ensure the profit of the gaming facility.

  For example, the first type symbol sequence and the second type symbol sequence on the left side of FIG. 1D indicate immediately before the movement of the symbol, and the first type symbol sequence and the second type symbol sequence on the right side of FIG. Immediately after moving. As described above, FIG. 1D shows the state immediately before and after the movement of the symbol, and symbols other than the symbol to be moved are displayed at the same position.

  A thick solid square in FIG. 1D indicates a symbol display device (display area). The player can visually recognize the symbol located inside the square. FIG. 1D also shows the first type symbol column and the second type symbol column separately for the sake of clarity.

  In the example shown in FIG. 1D, there are P1, P2, P3, P4,. The position of P1 is closest to the symbol display device, and gradually moves away from the symbol display device in the upstream direction in the order of P2, P3, P4,.

  Immediately before the movement of the symbol (left side of FIG. 1D), the symbol C of the first type symbol column and the symbol 1 of the second type symbol column are displayed in an overlapping manner on the first stage of the symbol display device. On the second stage of the symbol display device, the symbol D of the first type symbol column and the symbol 2 of the second type symbol column are displayed in an overlapping manner. On the third stage of the symbol display device, the symbol E of the first type symbol column and the symbol 3 of the second type symbol column are displayed in an overlapping manner. On the fourth stage of the symbol display device, the symbol F of the first type symbol column and the symbol 4 of the second type symbol column are displayed in an overlapping manner.

  Immediately before the movement of the symbol (left side in FIG. 1D), the symbol B of the first type symbol column and the symbol 7 of the second type symbol column are superimposed on P1. The symbol A of the first type symbol row and the symbol 6 of the second type symbol row are displayed overlapping P2. In P3, the symbol L of the first type symbol column and the symbol 5 of the second type symbol column are displayed overlapping each other. The symbol K of the first type symbol row and the symbol 4 of the second type symbol row are displayed overlapping P4.

  Further, immediately after the movement of the symbol (right side in FIG. 1D), the same symbols as before the symbol movement are displayed on the first, second, third, and fourth stages of the symbol display device.

  In the example shown in FIG. 1D, the symbol is moved using P3 as the symbol movement destination. For example, the symbol G of the first type symbol row moves to P3 (see arrow X in FIG. 1D), and the symbol 2 of the second type symbol row moves to P3 (see arrow Y in FIG. 1D). The symbol G of the first type of symbol sequence is a symbol determined by the first lottery process, and the symbol 2 of the second type of symbol sequence is a symbol determined by the second lottery process.

  It is preferable that the symbols are moved not by one symbol but by moving together the leading symbol and a plurality of symbols continuing upstream from the leading symbol. By moving a plurality of symbols, it is possible to make the symbol switching portion inconspicuous and make it difficult for the player to understand that the symbols have been moved.

  For example, as shown by a broken line in FIG. 1D, in the first type of symbol string, the symbol G that is the first symbol and a plurality of symbols that are upstream from the symbol G are moved. Similarly, in the second type of symbol string, the first symbol, symbol 2, and a plurality of symbols following the symbol 2 upstream are moved. The leading symbol of the first type symbol string is the symbol determined by the first lottery process, and the leading symbol of the second type symbol string is the symbol determined by the second lottery process.

  Therefore, in the first type of symbol string in FIG. 1D, five symbols from the symbol L located at P3 to the upstream symbol H are deleted, and the leading symbol G is connected to the symbol A located at P2. Thus, the first type symbol string is reconfigured. Further, in the second type symbol string, the three symbols from the symbol 5 positioned at P3 to the upstream symbol 3 are deleted, and the leading symbol 2 is connected to the symbol 6 positioned at P2, so that Reconstruct two types of symbol sequences.

  P1 to P4 in FIG. 1D are upstream positions from the symbol display device, and are downstream positions from the position before the leading symbol is moved. In this way, the first symbol and the plurality of symbols following the first symbol upstream from the first symbol are moved to the downstream position, thereby being moved to a position close to the symbol display device. The second type symbol string is reconfigured.

  By moving the symbol to a position close to the symbol display device, the moved symbol can be scrolled and displayed immediately on the symbol display device, and even if the time until symbol rearrangement is prolonged, The time can be shortened and the time required for the unit game can be adjusted to be constant.

  In the above-described example, the case where the symbol is moved when the time until the symbol determined by the first lottery process or the second lottery process is rearranged is longer than the predetermined time is shown. That is, a case is shown in which whether or not to move a symbol is determined based on the time until rearrangement. The determination of whether to move the symbol is not limited to time. For example, when the number of symbols until the symbols determined by the first lottery process or the second lottery process are rearranged exceeds a predetermined number, the symbols are moved to reconfigure the symbol string. It may be.

That is, the above-described process (4-2)
(4-2 ′) When the number of symbols until the symbols determined by the first lottery process are rearranged exceeds a predetermined number, the symbol determined by the first lottery process A process of moving the position to a position downstream of the scroll to reconstruct the first type of symbol string (for example, a process in step S4515 in FIG. 45 described later) can be performed.

In addition, the above-described processing (4-3)
(4-3 ′) If the number of symbols until the symbols determined by the second lottery process are rearranged exceeds a predetermined number, the number of symbols determined by the second lottery process The position can be moved to a position downstream of the scroll to reconstruct the second type symbol string (for example, the process in step S4519 in FIG. 45 described later).

The gaming machine according to the present embodiment further includes
The downstream position is a position from the display area toward the upstream of the scroll by a number smaller than the number of symbols displayed along the scroll direction of the display area of the symbol display device.

  The leading symbol to be moved is moved to a position downstream of the scroll. For example, in FIG. 1D, the leading symbol is moved to P3 as the movement destination.

  The position of the symbol movement destination can be determined based on the number of symbols displayed in the scroll direction on the symbol display device. For example, it is possible to set the position upstream from the symbol display device by a number smaller than the number of symbols to be displayed.

  As shown in FIG. 1D, symbols are displayed at four positions of the first, second, third, and fourth stages of the symbol display device. In this example, the number of symbols displayed on the symbol display device along the scroll direction is four. A position heading upstream from the symbol display device by a number (1 to 3) smaller than four is one of the three positions P1 to P3 in FIG. 1D.

  Since the symbol is moved upstream by a number smaller than the number of symbols displayed along the scroll direction in the display area, the symbol is moved to a position closer to the symbol display device, and the symbol is immediately displayed on the symbol display device. Can appear.

  Instead of using the number of symbols displayed in the scroll direction on the symbol display device as a reference, the position of the symbol movement destination may be determined randomly.

<<< basic concept >>>
The slot machine 10 is a kind of gaming machine. In the present embodiment, the slot machine 10 is described as an example of a gaming machine, but the present invention is not limited to this. The slot machine 10 has a base game mode, a free game mode, and a jackpot game mode. The slot machine 10 may be any device that can shift from the base game mode to the free game mode or the jackpot game mode. The free game mode and the jackpot game mode may be game modes different from the base game mode.

  In the present embodiment, a game executed in the base game mode is referred to as a base game. A game executed in the free game mode is referred to as a free game. A game executed in the jackpot game mode is referred to as a jackpot game. The base game and the free game are slot games in which a plurality of symbols are rearranged. A base game and a free game are games in which unit games can be repeated. The jackpot game is a selection game in which a player selects an option, and a game result is determined by the selected option. The free game and the jackpot game function as feature games.

  In the base game mode and the free game mode, when a unit game starts, a symbol to be stopped is determined by lottery processing. A stop scheduled symbol is determined for each of the five video reels 3a to 3e. In this embodiment, as will be described later, video reels 3a to 3e are configured by overlapping two types of reel bands.

  Next, the rearrangement of a plurality of symbols is once canceled. When the rearrangement of the plurality of symbols is canceled, the symbols are displayed in a variable manner (symbol column scroll display described later). After a predetermined time has elapsed, the scheduled stop symbol is stopped and displayed (displayed in a stopped manner) at a predetermined reference position. A plurality of symbols are rearranged in the symbol display area 141d by the stop display of the symbols to be stopped. By rearranging the plurality of symbols, the result of the unit game is displayed in the symbol display area 141d. In the present embodiment, symbol stop display is synonymous with the appearance and rearrangement of symbols.

  The rearrangement means a state in which symbols are again arranged in the symbol display area 141d after the symbol arrangement is canceled by the start of the unit game. In this way, the arrangement of the symbols is once canceled by the start of the unit game (slot game), and then the symbols are arranged again (rearrangement), and the result of the unit game is determined by the rearranged symbols, The unit game ends. “Arrangement” means that the symbol can be visually confirmed by the player.

  The symbols are not limited to the type and number as long as they are rearranged so as to be visible to the player in the symbol display area 141d of the lower display device 141 (lower liquid crystal display panel 141b).

  The base game mode is a game mode in which a unit game (base game) in which a plurality of symbols are rearranged in the symbol display area 141d and a payout according to the rearranged symbols is paid out on condition that a bet of game value is made. is there. The base game is not limited to the slot game, and may be a game that can be executed independently in a game terminal device (gaming machine) such as the slot machine 10.

  The game value is a coin, a bill, or electronic valuable information corresponding to these. The game value in the present embodiment is not particularly limited, and may be a game medium such as a medal, token, electronic money, or ticket. The ticket is not particularly limited and may be, for example, a ticket with a barcode.

  The free game mode and the jackpot game mode are game modes different from the base game mode, and may be game modes that can obtain more profit than the base game mode.

<<<<< Specific Outline of Slot Machine of this Embodiment >>>>
The outline of the slot machine of the present embodiment is as follows. Details will be described later.

<Video reels 3a, 3b, 3c, 3d, 3e>
The slot machine 10 has five video reels 3a, 3b, 3c, 3d, and 3e.

<Normal reel band and reel band for jackpot>
In the slot machine 10 of the present embodiment, each of the five video reels 3a, 3b, 3c, 3d, 3e is constituted by two types of reel bands. As will be described later, the first type of reel band is five of normal reel bands 3n-a, 3n-b, 3n-c, 3n-d, and 3n-e (see FIGS. 11 to 30). . The second type of reel bands are three jackpot reel bands 3jp-a, 3jp-c, and 3jp-e (see FIGS. 31 to 41). Ordinary reel bands 3n-a, 3n-b, 3n-c, 3n-d, 3n-e correspond to the first type of symbol strings, and the jack band reel bands 3jp-a, 3jp-c, 3jp- e corresponds to the second type of symbol string.

  The number of symbols arranged on the normal reel bands 3n-a, 3n-b, 3n-c, 3n-d, 3n-e, and the jackpot reel bands 3jp-a, 3jp-c, 3jp-e This is different from the number of symbols arranged in. The size of the symbol formation area where the symbols are formed in the normal reel band 3n is the same as the size of the symbol formation area where the symbols are formed in the jackpot reel band 3jp. That is, the size of one symbol (one cell) is the same for both the normal reel band 3n and the jackpot reel band 3jp.

  The game mode includes a base game mode and a free game mode. In the base game mode, the normal reel band 3n and the jackpot reel band 3jp are overlapped and displayed as video reels 3a, 3b, 3c, 3d, 3e. That is, in the base game mode, the symbols arranged on the normal reel band 3n and the symbols arranged on the jackpot reel band 3jp are displayed in an overlapping manner.

  Specifically, the video reel 3a is displayed by superimposing a normal reel band 3n-a and a jackpot reel band 3jp-a. Only the normal reel band 3n-b is displayed on the video reel 3b. The video reel 3c is displayed by superimposing a normal reel band 3n-c and a jackpot reel band 3jp-c. Only the normal reel band 3n-d is displayed on the video reel 3d. The video reel 3e is displayed by superimposing a normal reel band 3n-a and a jackpot reel band 3jp-e. Specific configurations of these two types of reel bands will be described later. When it is not necessary to distinguish the normal reel band 3n from the jackpot reel band 3jp, the reels 3a, 3b, 3c, 3d, and 3e will be simply described.

  The trigger for the jackpot is determined by the symbols arranged on the jackpot reel band 3jp. The establishment of a normal winning pattern other than the jackpot is determined by the symbols arranged on the normal reel band 3n. In the base game mode, the normal reel band 3n and the jackpot reel band 3jp are displayed so as to overlap each other, and the establishment of the normal winning pattern and the jackpot trigger may overlap.

  In the free game mode, only normal reel bands are displayed as video reels 3a, 3b, 3c, 3d, and 3e. That is, in the free game mode, only symbols arranged on the normal reel band are displayed. Therefore, in the free game mode, only a normal winning pattern can be established, and the jackpot is not triggered.

  The five video reels 3a to 3e are displayed as images on the lower liquid crystal display panel 141b of the lower display device 141. A plurality of symbols are arranged along the longitudinal direction of each of the five video reels 3a to 3e. A plurality of symbols arranged on each of the five video reels 3a to 3e are displayed as images.

<Symbol stop position>
The symbol stops along the video reel 3 at the four positions of the uppermost (first), upper middle (second), lower middle (third), and lowermost (fourth) as symbol stop positions. It is defined by the area 141d. Therefore, when the five video reels 3a to 3e (five reel bands) are stopped and displayed, a total of 20 symbols are reproduced in the symbol display area 141d by 5 × 4 rows (5 columns and 4 rows). Be placed.

  Thus, 20 stop positions of 5 × 4 stages are defined in the symbol display area 141d. Twenty cells for displaying symbols are constituted by the twenty stop positions. By stopping and displaying symbols at each of the 20 stop positions (cells), 20 symbols can be rearranged. A symbol matrix can be formed by rearranging 20 symbols.

<Type of symbol>
In the present embodiment, as symbols, WILD (wild symbol), RED, PURPLE, GREEN, YELLOW, BLUE, ACE, KING, QUEEN, JACK, TEN, NINE, FEATURE (trigger symbol, retrigger symbol), JP (jackpot) Symbol) and BLANK (blank).

  WILD, RED, PURPLE, GREEN, YELLOW, BLUE, ACE, KING, QUEEN, JACK, TEN, NINE, FEATURE are normal reel bands 3n-a, 3n-b, 3n-c, 3n-d, 3n-e Placed in. JP and BLANK are arranged on reel bands 3jp-a, 3jp-c, and 3jp-e for jackpots.

  WILD (wild symbol), FEATURE (trigger symbol, retrigger symbol), JP (jackpot symbol), and BLANK (blank) function as specific symbols. Symbols other than the specific symbol are normal symbols.

  A wild symbol is a symbol that can be substituted for other types of symbols. The wild symbol is replaced with another symbol so that an advantageous winning pattern is established.

  The trigger symbol is a symbol serving as a trigger for shifting from the base game mode to the free game mode. The retrigger symbol is a symbol that serves as a retrigger for maintaining the free game mode.

  In the free game mode, at least one specific symbol of a trigger symbol, a retrigger symbol, and a wild symbol may be increased. The trigger symbol and the retrigger symbol may increase the number of games in the free game mode.

  FEATURE, which is a trigger symbol and retrigger symbol, is a scatter symbol. Even if the scatter symbols are not lined up in a left-to-right manner in the symbol display area 141d, a winning pattern is established when a predetermined number, for example, three FEATUREs are determined by symbol lottery processing. To do. For example, when it is determined that one FEATURE appears on the video reel 3b, one FEATURE appears on the video reel 3c, and one FEATURE appears on the video reel 3d, the winning pattern is determined. To establish.

  JP (jackpot symbol) is a symbol serving as a trigger for shifting from the base game mode to the jackpot game mode. JP is also a scatter symbol. Therefore, even when not connected in a left-to-right manner, a winning pattern is established when it is determined by the symbol lottery processing so that a predetermined number, for example, three Jp appear in the symbol display area 141d. For example, when it is determined that one JP on the video reel 3a, one JP on the video reel 3c, and one JP on the video reel 3e appear in the symbol display area 141d, the winning pattern is changed. To establish.

  As described above, the JP is disposed only on the reels 3jack-a, 3jp-c, and 3jp-e for jackpots. Accordingly, there are cases where the winning pattern of the jackpot overlaps with the winning pattern formed by the symbols of the normal reel band. For example, a free game mode winning pattern based on FEATURE of a normal reel band and a jackpot winning pattern based on JP of a jackpot reel band may be established in an overlapping manner.

  BLANK is a symbol that does not constitute a winning pattern. Therefore, even when a plurality of BLANKs are arranged at the stop positions where they are validated, they do not function as normal symbols and do not constitute a winning pattern. The effective stop position will be described later. Also, BLANK does not function as a scatter symbol and does not constitute a winning pattern even if a plurality of BLANKs appear.

  In the present embodiment, it is possible to make the player visually recognize that no picture or design is formed on BLANK and that no winning pattern is formed. For example, it is preferable that it is composed of a single color. BLANK includes those that occupy most of the monochrome area even if a pattern such as a decorative pattern is drawn, and those that can be visually recognized as a monochrome area even if a pattern such as a pattern is drawn. .

  Symbols other than the specific symbol are normal symbols. When a winning pattern is established by a normal symbol, a payout amount corresponding to a payout corresponding to the winning pattern is paid out.

<Establishment of winning pattern>
No payline is formed in the symbol display area 141d of the slot machine 10. When the rearranged symbols are arranged in a left-to-right manner at an activated stop position (see FIGS. 7 and 8), a winning pattern is established (see FIG. 10 described later).

<BET operation>
There are two types of BET operations on the slot machine 10: WAYS BET and Bet Multiplier.

<WAYS BET>
The WAYS BET is determined by the operation of five “4 WAYS” buttons 40, “16 WAYS” buttons 41, “64 WAYS” buttons 42, “256 WAYS” buttons 43, and “1024 WAYS” buttons 44 (see FIG. 4). The

  By the WAYS BET, the normal reel band 3n is selected in the base game mode and the free game mode. Further, the number of BETs is determined by WAYS BET. Further, the WAYS BET determines the stop position of the symbol to be effective.

<Select reel band>
In both the base game mode and the free game mode, the normal reel bands 3n-a, 3n-b, 3n-c, 3n-d, and 3n-e are selected by the WAYS BET.

  Specifically, when the “4 WAYS” button 40 is operated in the base game mode, a set of symbol columns shown in FIGS. 11 and 12 is selected as the normal reel band 3n. When the “16 WAYS” button 41 is operated in the base game mode, the symbol string set shown in FIGS. 13 and 14 is selected as the normal reel band 3n. When the “64 WAYS” button 42 is operated in the base game mode, the symbol string set shown in FIGS. 15 and 16 is selected as the normal reel band 3n. When the “256 WAYS” button 43 is operated in the base game mode, the symbol string set shown in FIGS. 17 and 18 is selected as the normal reel band 3n. When the “1024 WAYS” button 44 is operated in the base game mode, a set of symbol columns shown in FIGS. 19 and 20 is selected as the normal reel band 3n.

  Further, in the base game mode, a combination of jackpot reel bands 3jp-c and 3jp-e is selected by WAYS BET. Specifically, when the “4 WAYS” button 40 is operated, the symbol string set shown in FIG. 37 is selected as the jackpot reel bands 3jp-c and 3jp-e. When the “16 WAYS” button 41 is operated, a set of symbol strings shown in FIG. 38 is selected as the reels 3jack-c and 3jp-e for the jackpot. When the “64 WAYS” button 42 is operated, a set of symbol columns shown in FIG. 39 is selected as the reels 3jack-c and 3jp-e for jackpots. When the “256 WAYS” button 43 is operated, a set of symbol columns shown in FIG. 40 is selected as the reels 3jack-c and 3jp-e for jackpots. When the “1024 WAYS” button 44 is operated, a set of symbol columns shown in FIG. 41 is selected as the reels 3jack-c and 3jp-e for the jackpot.

  In the free game mode, when the “4 WAYS” button 40 is operated, a set of symbol columns shown in FIGS. 21 and 22 is selected as the normal reel band 3n. When the “16 WAYS” button 41 is operated in the free game mode, the symbol string set shown in FIGS. 23 and 24 is selected as the normal reel band 3n. When the “64 WAYS” button 42 is operated in the free game mode, the symbol string set shown in FIGS. 25 and 26 is selected as the normal reel band 3n. When the “256 WAYS” button 43 is operated in the free game mode, a set of symbol rows shown in FIGS. 29 and 30 is selected as the normal reel band 3n. When the “1024 WAYS” button 44 is operated in the free game mode, a set of symbol columns shown in FIGS. 31 and 32 is selected as the normal reel band 3n.

<BET number>
Further, the number of BETs is determined by the WAYS BET (see FIG. 9). Specifically, when the “4 WAYS” button 40 is operated, the BET number is determined to be 1. When the “16 WAYS” button 41 is operated, the BET number is determined to be 10. When the “64 WAYS” button 42 is operated, the BET number is determined to be 20. When the “256 WAYS” button 43 is operated, the BET number is determined to be 30. When the “1024 WAYS” button 44 is operated, the BET number is determined to be 50.

<Effective symbol stop position>
Depending on the WAYS BET, the number of symbol stop positions to be activated changes. That is, in the present embodiment, the payline is not activated by the BET operation, but the stop position to be activated is determined from the 40 stop positions by the WAYS BET operation. For example, as shown in FIGS. 7 and 8 to be described later, the stop position (white cell) to be validated and the stop position (cells with hatching) to be invalidated are determined by the WAYS BET operation.

<< BET Multiplier >>
The BET Multiplier includes five “BET × 1” buttons 34, “BET × 2” buttons 35, “BET × 3” buttons 37, “BET × 4” buttons 38, and “BET × 5” buttons 39 (see FIG. 4). Determined by the operation.

  The BET Multiplier has a first setting pattern and a second setting pattern. The first setting pattern and the second setting pattern are set in advance by the operation of the manager of the game facility.

  The BET Multiplier determines a payout rate. Also, the reel band 3jp-a for jackpot is selected by the BET Multiplier. The magnification for the payout is determined according to the first setting pattern and the second setting pattern. The jackpot reel band 3jp-a is determined in accordance with the magnification for the payout.

<Multiple for dividend>
In the base game mode, the BET Multiplier determines a payout rate. The magnification for the payout is determined according to the first setting pattern and the second setting pattern.

  In the first setting pattern, when the “BET × 1” button 34 is operated, the magnification is determined to be 1. When the “BET × 2” button 35 is operated, the magnification is determined to be double. When the “BET × 3” button 37 is operated, the magnification is determined to be three times. When the “BET × 4” button 38 is operated, the magnification is determined to be four times. When the “BET × 5” button 39 is operated, the magnification is determined to be 5 times.

  In the second setting pattern, when the “BET × 1” button 34 is operated, the magnification is determined to be 1. When the “BET × 2” button 35 is operated, the magnification is determined to be double. When the “BET × 3” button 37 is operated, the magnification is determined to be three times. When the “BET × 4” button 38 is operated, the magnification is determined to be 5 times. When the “BET × 5” button 39 is operated, the magnification is determined to be 10 times.

<Selection of reel band 3jp-a>
The jackpot reel band 3jp-a is determined in accordance with the magnification for the payout. When the magnification is 1, the symbol string shown in FIG. 31 is selected as the reel 3jp-a for jackpot. When the magnification is 2 times, the symbol string shown in FIG. 32 is selected as the jackpot reel band 3jp-a. When the magnification is 3 times, the symbol string shown in FIG. 33 is selected as the reel 3jp-a for jackpot. When the magnification is four times, the symbol string shown in FIG. 34 is selected as the jackpot reel band 3jp-a. When the magnification is 5 times, the symbol string shown in FIG. 35 is selected as the reel band 3jp-a for jackpot. When the magnification is 10 times, the symbol string shown in FIG. 36 is selected as the jackpot reel band 3jp-a.

<Free game mode>
In the base game mode, FEATURE appears on the video reels 3b, 3c, 3d to trigger the free game mode (see FIG. 6). If FEATURE appears in the symbol display area 141d regardless of the validation and invalidation of the stop position, the winning pattern can be determined and the free game mode can be triggered.

  In the free game mode, eight unit games (free games) can be played (see FIG. 6). In the free game mode, a reel band different from that in the base game mode is used. In the free game mode, FEATURE appears on the video reels 3b, 3c, 3d to retrigger the free game (see FIG. 6). By retrigger, 8 unit games are added. There is no upper limit on the number of retriggers.

  In the free game mode, the reel band for the free game mode in which the number of top symbols is larger than that in the base game mode is used. Reel bands having different lengths are selected by the BET operation.

<Jackpot game mode>
In the base game mode, when the JP appears on the video reels 3a, 3c, 3e, the jackpot mode is triggered (see FIG. 6). If JP also appears in the symbol display area 141d regardless of the validation and invalidation of the stop position, it becomes a target for the determination of the winning pattern, and the jackpot mode can be triggered. The jackpot mode can be triggered only in the base game mode. As the number of BETs increases, the appearance rate of JP increases.

  In the jackpot game mode, the type of jackpot is determined by the player selecting an option. The type of jackpot is determined in advance by lottery, and the result is not changed by the player's selection operation.

  The slot machine 10 has four types of stand-alone jackpots. The four types of jackpots are GRAND, MAJOR, MINOR, and MINI. In the jackpot game mode, one of GRAND, MAJOR, MINOR, and MINI is determined according to the option selected by the player. In one jackpot game mode, one type of jackpot is determined. The initial value and increment rate of the jackpot can be set by a setting combination (SC01 to SC08 described later).

<< Game state transition >>
FIG. 6 is a diagram showing state transition in the slot machine 10. Specifically, it is a diagram showing transitions between a base game mode, a free game mode, and a jackpot game mode.

  The slot machine 10 has three types of game modes including a base game mode, a free game mode, and a jackpot game mode. In the slot machine 10, the unit game is executed mainly in the base game mode, and when the free game is triggered (event) in the base game mode, the free game mode is entered. When the jackpot game mode is triggered (event) in the base game mode, the mode shifts to the jackpot game mode.

  As shown in FIG. 6, in the base game mode, the unit game is repeated until the free game is triggered. A unit game in the base game mode is a game that can be started by consuming (BET) a game medium. In the game in the base game mode, when any of the winning patterns shown in FIG. 10 is established, a payout amount corresponding to the payout corresponding to the winning pattern is paid out.

  In the base game mode, when the FEATURE winning pattern is established, the free game mode is triggered. Specifically, the FEATURE winning pattern is established by determining that three FEATUREs appear. For example, the FEATURE winning pattern is established by determining that one FEATURE appears on each of the video reels 3b, 3c, and 3d.

  FEATURE is a scatter symbol, and it is determined whether a winning pattern is established regardless of whether the stop position of the symbol is valid or invalid. Whether or not the winning pattern is established is determined by the number of rearranged FEATUREs.

  By triggering the free game mode, the game mode shifts to the free game mode. 47 to 49 described later, a free game is executed, and a payout amount corresponding to a predetermined payout is paid out.

  In the free game mode, a unit game can be started without consuming game media. In the free game mode, the player can play a unit game up to eight times in principle.

  By retriggering the free game mode in the free game mode, the game mode is maintained in the free game mode. In the base game mode, the free mode is retriggered when the winning pattern of FEATURE is established. The conditions for establishing a retrigger are the same as the conditions for establishing a trigger, and the FEATURE winning pattern is established by determining that three FEATUREs appear. By retriggering the free game mode, 8 unit games are added.

  When all the unit games are finished, the free game mode returns to the base game mode.

  In the base game mode, when the JP winning pattern is established, the jackpot game mode is triggered. Specifically, a winning pattern of JP is established by determining that three JPs appear. For example, a winning pattern of JP is established by determining that one JP appears on each of the video reels 3a, 3c, and 3e.

  JP is a scatter symbol, and it is determined whether a winning pattern is established regardless of whether the stop position of the symbol is valid or invalid. Whether or not the winning pattern is established is determined by the number of JPs rearranged.

  By triggering the jackpot game mode, the game mode shifts to the jackpot game mode. A jackpot game is executed by the processing shown in FIGS.

  The jackpot game is a selection game in which a player can select an option. The type of jackpot corresponding to the option selected by the player is determined. The four types of jackpots are GRAND, MAJOR, MINOR, and MINI. One type of these is determined by the selection operation of the player. For example, GRAND wins with a probability of 500 / 3,443,698, MAJOR wins with a probability of 20,000 / 3,443,698, and MINOR has a probability of 420,000 / 3,443,698. Then, MINI wins with a probability of 3,003, 198/3, 443, 698 (see FIG. 57).

  In this embodiment, the jackpot is a stand-alone type. The progressive amount is determined for each slot machine 10. Details of the jackpot will be described later.

  In the network type, a part of the game medium consumed by the player in each slot machine 10 is transmitted to the external control device as a jackpot amount, and the external control device accumulates the received jackpot amount and shares it with each gaming machine. To do. When a predetermined type of jackpot is won, the amount of jackpot is transmitted from the external control device to the slot machine 10.

<Validation or invalidation of stop position, judgment of winning pattern>
In the slot machine 10 of the present embodiment, no payline is formed. Therefore, no payline is selected by the BET operation. In the present embodiment, instead of selecting a payline, a symbol stop position is selected by enabling or disabling the symbol stop position.

  As described above, in the symbol display area 141d, 20 stop positions are defined by 5 lines × 4 stages. Twenty cells for displaying symbols are constituted by the twenty stop positions. In the present embodiment, activation and invalidation of 20 cells are determined by operating the “WAYS BET” button.

  By operating the “4 WAYS” button 40, four stop positions (uppermost, upper middle, lower middle, and lowermost) of one video reel 3a and upper and middle stages of the four video reels 3b to 3e are effective. (FIG. 7a). The remaining stop positions are invalidated.

  By operating the “16 WAYS” button 41, four stop positions (uppermost, upper middle, lower middle, and lowermost) of the two video reels 3a and 3b, and upper and middle stages of the three video reels 3c to 3e, Is activated (FIG. 7b). The remaining stop positions are invalidated.

  By operating the “64 WAYS” button 42, four stop positions (uppermost, upper middle, lower middle, and lowermost) of the three video reels 3a to 3c, and upper and middle stages of the two video reels 3d and 3e, Is activated (FIG. 7c). The remaining stop positions are invalidated.

  By operating the “256 WAYS” button 43, the four stop positions (uppermost, upper middle, lower middle, and lowermost) of the four video reels 3a to 3d and the upper and middle stages of one video reel 3e are effective. (FIG. 7d). The remaining stop positions are invalidated.

  By operating the “1024 WAYS” button 43, the four stop positions (the uppermost, upper middle, lower middle, and lowermost) of the five video reels 3 a to 3 e are activated and all 20 cells are activated. (FIG. 7e).

  In FIGS. 7a to 7e, activated cells are shown in white, and disabled cells are shown with hatching.

  There are 13 types of winning patterns as shown in FIG. The winning pattern is composed of an array of a plurality of symbols. The specific contents of the winning pattern will be described with reference to FIG.

  The winning pattern is determined by LEFT TO RIGHT for the five video reels 3a to 3e for the activated cells except for FEATURE and JP. That is, the winning pattern is determined over a plurality of video reels 3 starting from the leftmost video reel 3a and continuing toward the video reel 3e.

  From the above, first, the winning pattern is determined for the symbols displayed in the activated cells except for FEATURE and JP. Further, even when symbols are continuously arranged across a plurality of video reels 3, if no symbol is displayed on the leftmost video reel 3a, a winning pattern is not established. Even if symbols are displayed on the leftmost video reel 3a, the winning pattern is not established even when the symbols are arranged discontinuously.

  In the case shown in FIG. 7a, starting from any one of the four cells (uppermost, upper middle, lower middle, and lowermost) of the video reel 3a, the upper and middle cells of the four video reels 3b to 3e The winning pattern is determined by the symbols arranged in succession.

  In the case shown in FIG. 7b, it starts from one of the four cells (uppermost, upper middle, lower middle, and lowermost) of the video reel 3a, and the four cells (uppermost, upper middle, The winning pattern is determined by the symbols continuously arranged in any one of the cells in the lower middle stage and the lowermost stage and the upper middle cells of the three video reels 3c to 3e.

  In the case shown in FIG. 7c, the cell starts from one of the four cells (uppermost, upper middle, lower middle, and lowermost) of the video reel 3a, and the four cells (uppermost, upper middle, Any one of the cells in the lower middle stage and the lowermost stage, and any one of the four cells on the video reel 3c (the uppermost stage, the upper middle stage, the lower middle stage, the lowermost stage), and the two video reels 3d and 3e. A winning pattern is determined based on symbols continuously arranged in the middle cell.

  In the case shown in FIG. 7d, the four cells of the video reel 3b start from any one of the four cells (the uppermost, upper middle, lower middle, and lowermost), and the four cells of the video reel 3b (the uppermost, upper middle, Any one of the cells in the lower middle stage and the lowermost stage, four cells on the video reel 3c (the uppermost stage, the upper middle stage, the lower middle stage, the lowermost stage), and four cells on the video reel 3d (the uppermost stage) , An upper middle stage, a lower middle stage, and a lowermost stage) and a winning pattern is determined by symbols arranged continuously in the upper middle cell of one video reel 3e.

  In the case shown in FIG. 7e, the cell starts from any one of the four cells (uppermost, upper middle, lower middle, and lowermost) of the video reel 3a, and the four cells (uppermost, upper middle, Any one of the cells in the lower middle stage and the lowermost stage, four cells on the video reel 3c (the uppermost stage, the upper middle stage, the lower middle stage, the lowermost stage), and four cells on the video reel 3d (the uppermost stage) , Upper middle, lower middle, and lowermost) and any of the four cells (top, upper middle, lower middle, and lowermost) of video reel 3e. The winning pattern is determined by the symbol.

  FIG. 8 is a diagram illustrating an example of the case of FIG. In other words, this is an example when all of the 20 cells are activated.

  “PICT A” shown in FIG. 7 is one of the normal symbols RED, PURPLE, GREEN, YELLOW, BLUE, ACE, KING, QUEEN, JACK, TEN, and NINE. “WILD” in FIG. 7 is WILD.

  In the example shown in FIG. 7, since all of the 20 cells are activated, it is only necessary to start from the leftmost video reel 3a and continue toward the video reel 3e.

  The winning pattern indicated by the solid line in FIG. 7 starts from the lowermost cell of the video reel 3a, the uppermost cell of the video reel 3b, the uppermost cell of the video reel 3c, and the lower middle cell of the video reel 3d. It is established by symbols arranged continuously in the upper and middle cells of the video reel 3e. Since the lower middle cell of the video reel 3d is WILD, it is replaced with “PICT A”. Therefore, along the solid line, five “PICT A” s are successively arranged to form a winning pattern.

  The winning pattern indicated by the broken line in FIG. 7 starts from the lowermost cell of the video reel 3a, the uppermost cell of the video reel 3b, the uppermost cell of the video reel 3c, and the lower middle cell of the video reel 3d. It is established by symbols arranged continuously in the lower middle cell of the video reel 3e. WILD is replaced by “PICT A”. Therefore, along the broken line, five “PICT A” s are continuously arranged to form a winning pattern.

  7 starts from the lowermost cell of the video reel 3a, the uppermost cell of the video reel 3b, the uppermost cell of the video reel 3c, and the lower middle cell of the video reel 3d. And the symbols continuously arranged in the lowermost cell of the video reel 3e. WILD is replaced by “PICT A”. Accordingly, along the one-dot chain line, five “PICT A” are continuously arranged to form a winning pattern.

  Thus, in the present embodiment, the winning pattern is determined without using the payline. As described above, even when FEATURE and JP are displayed in the invalidated cell, it is determined that the winning pattern is established.

<Payout table>
FIG. 10 is a diagram illustrating an example of a payout table. The payout table shown in FIG. 10 defines 13 types of winning patterns and corresponding payouts.

  The payout table shows the relationship between the winning pattern, the number of Kinds of symbols, and the payout. The Kind number means the number of symbols constituting the winning pattern, and means the number of symbols arranged continuously from the left side to the right side.

  As described above, the formation of the winning pattern is determined by LEFT TO RIGHT except for FEATURE and JP. Accordingly, the payout is determined by the type and number of symbols arranged continuously in LEFT TO RIGHT.

  The first winning pattern is a pattern when WILDs are arranged. No dividend is specified for WILD itself.

  WILD is a symbol for replacing with another symbol so that an advantageous winning pattern is established. When WILD is replaced with another symbol and a final winning pattern is established, a payout corresponding to the winning pattern is determined. In the present embodiment, WILD is not replaced with FEATURE.

  The second winning pattern is a pattern when 2 to 5 REDs are continuously arranged. For example, the payout when 5 REDs are continuously arranged is defined as 50.

  The third winning pattern is a pattern when 3 to 5 PURPLEs are continuously arranged. For example, the payout when five PURPLEs are continuously arranged is defined as 40.

  The fourth winning pattern is a pattern when three to five greens are continuously arranged. For example, the payout when 5 GREENs are continuously arranged is defined as 40.

  The fifth winning pattern is a pattern when 3 to 5 YELLOWs are continuously arranged. For example, the payout when 5 YELLOWs are continuously arranged is defined as 25.

  The sixth winning pattern is a pattern when 3 to 5 BLUEs are continuously arranged. For example, the payout when 5 BLUEs are continuously arranged is defined as 25.

  The seventh winning pattern is a pattern when 3 to 5 ACEs are continuously arranged. For example, the payout when 5 ACEs are continuously arranged is defined as 15.

  The eighth winning pattern is a pattern when 3 to 5 KINGs are continuously arranged. For example, the payout when five KINGs are continuously arranged is defined as 14.

  The ninth winning pattern is a pattern when 3 to 5 QUEENs are continuously arranged. For example, the payout when 5 QUEENs are continuously arranged is defined as 13.

  The tenth winning pattern is a pattern when 3 to 5 JACKs are continuously arranged. For example, the payout when 5 JACKs are continuously arranged is defined as 12.

  The eleventh winning pattern is a pattern when three to five TENs are continuously arranged. For example, the payout when 5 TENs are continuously arranged is defined as 11.

  The twelfth winning pattern is a pattern when 3 to 5 NINEs are continuously arranged. For example, the payout when 5 NINEs are continuously arranged is defined as 11.

  The thirteenth winning pattern is a pattern when three FEATUREs appear. As described above, FEATURE is a scatter symbol. Therefore, the succession of FEATUREs is not a condition for the success or failure of the winning pattern, but the success or failure of the thirteenth winning pattern is determined based on the number of occurrences of FEATURE. The payout when three FEATUREs appear is defined as 2.

  As described above, the free game mode is triggered on the condition that it is determined by the symbol lottery process so that three FEATUREs appear. Therefore, when it is determined by the symbol lottery process so that three FEATUREs appear, the player is given both a payout and a shift to the free game mode.

  In the base game mode, the normal reel band 3n shown in FIGS. 11 to 20, the jackpot reel band 3jp-a shown in FIGS. 31 to 36, and the jackpot reel band shown in FIGS. 3jp-c and 3jp-e are superimposed and displayed as video reels 3a, 3b, 3c, 3d, and 3e.

  In the free game mode, only the normal reel band 3n shown in FIGS. 21 to 30 is displayed as the video reels 3a, 3b, 3c, 3d, and 3e.

  As shown in FIG. 11 to FIG. 20 and FIG. 21 to FIG. 30, the normal reel band 3n is specified as normal symbols RED, PURPLE, GREEN, YELLOW, BLUE, ACE, KING, QUEEN, JACK, TEN, and NINE. Symbols WILD and FEATURE. The normal reel band 3n shown in FIG. 11 to FIG. 20 and FIG. 21 to FIG. 30 is configured such that the number of specific symbols WILD and FEATURE and the number of normal symbols are different from each other.

  As shown in FIGS. 31 to 36 and FIGS. 37 to 41, the reel band 3jp for jackpot is composed of only two specific symbols JP and BLANK. The jackpot reel strip 3jp shown in FIGS. 31 to 36 and FIGS. 37 to 41 is configured so that the number of JPs is different from each other.

  The number of JPs in the reel band 3jp-a shown in FIG. The number of JPs in the reel band 3jp-a shown in FIG. The number of JPs in the reel band 3jp-a shown in FIG. The number of JPs in the reel band 3jp-a shown in FIG. The number of JPs in the reel band 3jp-a shown in FIG. The number of JPs in the reel band 3jp-a shown in FIG. In this way, it is stipulated that the number of JPs increases as the rate for payout increases.

  The relationship between the payout ratio and the number of JPs is summarized as follows.

  As described above, according to the first setting pattern or the second setting pattern, by operating the “BET × 1” button 34 to the “BET × 5” button 39, the payout rate is 1, 2, 3, It is determined as 4, 5, or 10.

  When the magnification is 1, the reel band 3jp-a shown in FIG. 31 is selected. That is, when the magnification is 1, the number of JP is one.

  When the magnification is 2, the reel band 3jp-a shown in FIG. 32 is selected. That is, when the magnification is two, the number of JPs is two.

  When the magnification is 3, the reel band 3jp-a shown in FIG. 33 is selected. That is, when the magnification is 3 times, the number of JPs is 3.

  When the magnification is 4, the reel band 3jp-a shown in FIG. 34 is selected. That is, when the magnification is 4, the number of JPs is 4.

  When the magnification is 5, the reel band 3jp-a shown in FIG. 35 is selected. That is, when the magnification is 5, the number of JPs is 5.

  When the magnification is 10, the reel band 3jp-a shown in FIG. 36 is selected. That is, when the magnification is 10, the number of JPs is 10.

  That is, the jackpot reel band 3jp is configured such that the number of JPs of the jackpot reel band 3jp (second-type symbol column) increases as the payout ratio increases. Therefore, when the play is started with a higher magnification, the player can visually recognize that the JP of the reel band 3jp for jackpot is increasing even during scrolling, and can increase the expectation for the jackpot.

  The number of JPs in the reel band 3jp-c shown in FIG. 37 is 1, and the number of JPs in the reel band 3jp-e is 1. The number of JPs in the reel band 3jp-c shown in FIG. 38 is 10, and the number of JPs in the reel band 3jp-e is 1. The number of JPs in the reel band 3jp-c shown in FIG. 39 is 10, and the number of JPs in the reel band 3jp-e is 2. The number of JPs in the reel band 3jp-c shown in FIG. 40 is 10, and the number of JPs in the reel band 3jp-e is 3. The number of JPs in the reel band 3jp-c shown in FIG. 41 is 10, and the number of JPs in the reel band 3jp-e is 5. Thus, the number of JPs is specified to increase as the value of WAYS BET increases.

  From the above, the relationship between the number of BETs and the number of JPs is summarized as follows.

  When the “4 WAYS” button 40 is operated, the BET number is set to 1, and the reel band 3jp-c and the reel band 3jp-e shown in FIG. 37 are selected. That is, when the number of BETs is 1, the number of JPs is 2 in total, one (reel band 3jp-c) and one (reel band 3jp-e).

  When the “16 WAYS” button 41 is operated, the BET number is set to 10 and the reel band 3jp-c and the reel band 3jp-e shown in FIG. 38 are selected. That is, when the number of BETs is 10, the total number of JPs is 10 (reel band 3jp-c) and 1 (reel band 3jp-e).

  When the “64 WAYS” button 42 is operated, the BET number is set to 20, and the reel band 3jp-c and the reel band 3jp-e shown in FIG. 39 are selected. That is, when the number of BETs is 20, the total number of JPs is 12 (reel band 3jp-c) and 2 (reel band 3jp-e).

  When the “256 WAYS” button 43 is operated, the BET number is set to 30 and the reel band 3jp-c and the reel band 3jp-e shown in FIG. 40 are selected. That is, when the number of BETs is 30, the number of JPs is 13 in total including 10 (reel band 3jp-c) and 3 (reel band 3jp-e).

  When the “1024 WAYS” button 44 is operated, the BET number is set to 50, and the reel band 3jp-c and the reel band 3jp-e shown in FIG. 41 are selected. That is, when the number of BETs is 50, the number of JPs is 15 (total of 10 reels (reel band 3jp-c) and 5 (reel bands 3jp-e)).

  That is, the jackpot reel band 3jp is configured such that the number of JPs of the jackpot reel band 3jp (second type symbol row) increases as the BET increases. Therefore, when playing is started with an increased number of BETs, the player can visually recognize that the JP of the reel band 3jp for jackpot is increasing even during scrolling, and can increase the expectation for the jackpot.

  The number of symbols of the normal reel band 3n shown in FIGS. 11 and 12 is 66 for the reel band 3n-a, 74 for the reel band 3n-b, and 72 for the reel band 3n-c. The reel bands 3n-d are 66 pieces, and the reel bands 3n-e are 70 pieces.

  13 and 14, FIG. 15 and FIG. 16, FIG. 17 and FIG. 18, and FIG. 19 and FIG. 20, the number of symbols in the normal reel band 3n is 62 for the reel band 3n-a. The reel bands 3n-b are 74, the reel bands 3n-c are 72, the reel bands 3n-d are 66, and the reel bands 3n-e are 70.

  As described above, the number of symbols in the jackpot reel band 3jp is defined more than the number of symbols in the normal reel band 3n. Therefore, the length of the jack strip reel band 3jp is longer than the length of the normal reel band 3n.

<< Program contents >>
Next, a program executed by the slot machine 10 will be described with reference to FIGS.

<Main control processing>
FIG. 42 is a flowchart showing the main control process. The game mode in the main control process of FIG. 42 is the base game mode.

  First, when the power is turned on to the slot machine 10, the main CPU 71 reads the authenticated game program and game system program from the memory card 54 via the gaming board 50, and writes them in the RAM 73 (step S4211).

  Next, the main CPU 71 performs an initialization process at the end of one game (step S4213). For example, unnecessary data for each unit game is cleared in the work area of the RAM 73, such as the number of BETs and symbols determined by lottery.

  Next, the main CPU 71 conducts coin insertion / start check processing which will be described later with reference to FIG. 43 (step S4215).

  Next, the main CPU 71 conducts symbol lottery processing in the base game mode, which will be described later with reference to FIG. 44 (step S4217). In this process, the symbol to be stopped is determined based on the random number for symbol determination.

  Next, the main CPU 71 conducts effect content start processing (step S4219). In the process of step S4219, the main CPU 71 extracts a random number for determining the effect, determines any of a plurality of predetermined effect contents by lottery, and executes the effect contents at the timing of the determined effect content. . For example, control is performed such as displaying an effect video on the upper display device 131, outputting sound from the speaker 112, turning on the lamp 111, and performing effect processing on these.

  Next, the main CPU 71 performs base game mode symbol display control processing, which will be described later with reference to FIG. 45 (step S4221). In this process, scrolling of the five video reels 3a to 3e (five reel bands) is started, and the scheduled stop symbol determined in the symbol lottery process in step S4217 is stopped at the reference position.

  Next, the main CPU 71 conducts a payout amount determination process which will be described later with reference to FIG. 46 (step S4223). In this process, it is determined whether or not the winning pattern of the payout table (see FIG. 10) has been established from the five symbols to be stopped stored in the symbol storage area by a symbol lottery process described later. The number of payouts is determined based on the payout table in accordance with the winning pattern and stored in a payout number storage area (payout number counter) provided in the RAM 73.

  Next, the main CPU 71 adds the increment amount to the accumulated amount (step S4224). The increment amount is an amount to be added to the accumulated amount for each unit game. The accumulated amount is an amount accumulated for each unit game.

  In the base game mode, the increment amount is added to the accumulated amount every time the unit game is executed. When the jackpot is won, the accumulated amount accumulated so far and the progressive initial amount are given to the player.

  The progressive initial amount is defined for each type of jackpot. For example, as shown in FIG. 56, GRAND JACKPOT Reset Value (Credits), MAJOR JACKPOT Reset Value (Credits), MINOR JACKPOT Reset Value (Credits), and MINI JAC KPOT ResetVs (CrSC) 8, It is prescribed.

  GRAND JACKPOT Reset Value (Credits) indicates the progressive initial amount of GRAND, MAJOR JACKPOT Reset Value (Credits) indicates the progressive initial amount of MAJOR, and MINOR JACKPOT Reset Value (CreditRight) , MINI JAC KPOT Reset Value (Credits) indicates the progressive initial amount of MINI.

  SC01 to SC08 indicate eight types of setting combinations. The setting combination can be set by the administrator of the slot machine 10. In this way, the progressive initial amount is defined in accordance with the type of jackpot and the setting combination.

  Specifically, as shown in FIG. 56, when the setting combination is SC01, the progressive initial amount of GRAND is 500,000, the progressive initial amount of MAJOR is 50,000, and the progressive amount of MINOR The initial amount is 4,000, and the progressive initial amount of MINI is 2,000.

  By setting the progressive initial amount, the progressive initial amount can be given to the player even when the progressive is established without being incremented.

  The increment amount is a value obtained by multiplying the BET number by the increment rate. 56, the increment rate is defined by GRAND JACKPOT Set Increment Percentage, MAJOR JACKPOT Set Increment Percentage, MINOR JACKPOT Set Increment Percentage, and MINI JAC CKPent Set SC1.

  GRAND JACKPOT Set Increment Percentage indicates the increment rate of GRAND, MAJOR JACKPOT Set Increment Percentage indicates the increment rate of MAJOR, MINOR JACKPOT Set Increment Percentage indicates the increment rate of MINOR JACKPOT Set Increment Percentage Indicates the increment rate of MINI. Thus, the increment rate is defined according to the type of jackpot and the setting combination.

  Specifically, when the setting combination is SC01, the GRAND increment rate is 0.1%, the MAJOR increment rate is 0.2%, and the MINOR increment rate is 0.8%. And the increment rate of MINI is 1.25%.

  For jackpots with a small increment rate, the cumulative amount can be increased by increasing the number of executions of the unit game. On the other hand, the jackpot with a large increment rate has a large accumulated amount even when the number of executions of the unit game is small.

  When the jackpot is won, the accumulated amount and the progressive initial amount are thus given to the player (see step S4629 in FIG. 46).

  Next, the main CPU 71 determines whether or not the jackpot game mode is triggered (step S4225). When determining that the jackpot game trigger has been established, the main CPU 71 executes the jackpot game mode process shown in FIG. 50 (step S4227), and returns the process to step S4213.

  Next, when the main CPU 71 determines in step S4225 that the jackpot game trigger has not been established, the main CPU 71 determines whether or not the free game mode has been triggered (step S4229). When determining that the free game trigger has been established, the main CPU 71 executes a free game mode process shown in FIG. 47 (step S4231), and returns the process to step S4213.

  Next, when the main CPU 71 determines in step S4231 that the free game trigger has not been established, the main CPU 71 performs a payout process (step S4233).

  The main CPU 71 adds the value (payout number counter) stored in the payout number storage area to the value (credit number counter) stored in the credit number storage area provided in the RAM 73. Alternatively, the ticket printer 120 may be controlled to emit a barcoded ticket in which a payout counter is recorded. Note that the driving of a hopper (not shown) may be controlled so that coins corresponding to the payout number counter are discharged from the coin payout exit.

  Next, the main CPU 71 returns the process to step S4213.

FIG. 43 is a flowchart showing a subroutine of coin insertion / start check processing.

  First, the main CPU 71 determines whether or not coin insertion has been detected by a coin counter (step S4311). When the main CPU 71 determines that the insertion of a coin has been detected, the main CPU 71 adds the value of the inserted coin to the value (credit number counter) stored in the credit number storage area (step S4313). In addition to coin insertion, it is determined whether bill insertion is detected by bill validator (for example, PTS terminal (not shown), etc.), and when it is determined that the insertion of banknote is detected, A value according to the above may be added to the credit counter.

  The main CPU 71 determines whether or not the credit number counter is 0 after step S 4313 or when it is determined in step S 4311 that coin insertion has not been detected (step S 4315). When the main CPU 71 determines that the credit number counter is not 0, the main CPU 71 permits operation acceptance of the WAYS BET button and the BET Multiplier button (step S4317).

  Next, the main CPU 71 determines whether or not an operation of the WAYS BET button has been detected (step S4319). When the main CPU 71 detects that the WAYS BET button has been pressed by the player using the WAYS BET switch, the main CPU 71 stores the type of the WAYS BET button in the RAM 73 (step S4321).

  Next, the main CPU 71 determines whether or not an operation of the BET Multiplier button has been detected (step S4323).

  Next, when the main CPU 71 detects that the BET Multiplier button has been pressed by the player using the BET Multiplier switch, the main CPU 71 stores the type of the BET Multiplier button in the RAM 73 (Step S4325).

  Next, after executing step S4325, the main CPU 71 permits operation acceptance of the spin button (step S4327).

  The main CPU 71 determines whether or not the operation of the spin button has been detected (step S4329). When determining that the operation of the spin button has not been detected, the main CPU 71 returns the process to step S4311.

  When determining that the operation of the spin button has been detected, the main CPU 71 calculates an increment amount and stores it in the RAM 73 (step S4331), and ends this subroutine. As described above, the increment amount is a value obtained by multiplying the BET number by the increment rate.

<Symbol lottery processing in base game mode>
FIG. 44 is a flowchart showing a subroutine of symbol lottery processing.

  First, the main CPU 71 extracts five random number values for determining symbols of the normal reel band in the base game mode (step S4411).

  Next, the main CPU 71 refers to the normal reel bands (symbol determination table) in the base game mode from the five random number values, and the normal reel bands 3n-a, 3n-b, 3n-c, 3n-d. , 3ne-e stop scheduled symbols are determined by lottery (step S4413).

  The process of step S4413 is a process of determining five scheduled stop symbols with reference to the normal reel band in the base game mode. In the present embodiment, the normal reel band 3n in the base game mode is the table shown in FIGS.

  When the “4 WAYS” button 40 is operated, the symbol strings shown in FIGS. 11 and 12 are selected. When the “16 WAYS” button 41 is operated, the symbol strings shown in FIGS. 13 and 14 are selected. When the “64 WAYS” button 42 is operated, the symbol strings shown in FIGS. 15 and 16 are selected. When the “256 WAYS” button 43 is operated, the symbol strings shown in FIGS. 17 and 18 are selected. When the “1024 WAYS” button 44 is operated, the symbol strings shown in FIGS. 19 and 20 are selected.

  By the processing of steps S4411 and S4413, five random numbers for symbol determination of the normal reel band 3n in the base game mode are extracted, and the symbols of the normal reel band 3n in the base game mode shown in FIGS. With reference to the determination table, one symbol is determined as a scheduled stop symbol for each of the five normal reel bands 3n-a to 3n-e. In the present embodiment, the five scheduled stop symbols are determined with equal probability.

  By the process of step S4413, five stop scheduled symbols corresponding to each of the five normal reel bands 3n-a to 3n-e are determined. Each of the five normal reel bands 3n-a to 3n-e is controlled to stop so that the determined five symbols to be stopped stop at the reference position of the symbol matrix (upper and middle stages of the symbol display area 141d). (See step S4521 in FIG. 45).

  Next, the main CPU 71 stores the determined to-be stopped symbols of the determined five normal reel bands 3n-a to 3n-e in a symbol storage area provided in the RAM 73 (step S4415).

  Next, the main CPU 71 determines one random value for determining symbols of the jackpot reel band 3jp-a in the base game mode, and determines symbols of the jackpot reel bands 3jp-c and 3jp-e. Two random numbers are extracted (step S4417).

  As shown in FIGS. 31 to 36, six types of symbol columns are defined as symbol columns constituting the jackpot reel band 3jp-a. As shown in FIGS. 37 to 41, five types of symbol columns are defined as symbol columns constituting the jackpot reel strips 3jp-c and 3jp-e. In the present embodiment, the symbol strings that constitute the reel band 3jp-a and the symbol strings that constitute the reel bands 3jp-c and 3jp-e are separately defined. Therefore, one random value is determined for determining the symbol of the reel band 3jp-a, and two random values are determined for determining the symbols of the reel bands 3jp-c and 3jp-e.

  Next, the main CPU 71 refers to the reel band 3jp-a (symbol determination table) in the base game mode from one random number value, and determines the stop symbol of the jackpot reel band 3jp-a by lottery. From the two random numbers, the reel bands 3jp-c and 3jp-e (symbol determination table) in the base game mode are referred to, and the symbols to be stopped for the jack belt reel bands 3jp-c and 3jp-e are obtained by lottery. Determination is made (step S4419).

  The processing in step S4419 is processing for determining three symbols to be stopped with reference to the reel band 3jp for jackpot in the base game mode. In this embodiment, the reel band 3jp for jackpot in the base game mode is a table shown in FIGS. 31 to 36 and FIGS. 37 to 41.

  When the multiplying factor for the payout is 1, the first symbol row shown in FIG. 31 is selected. When the magnification for the payout is double, the second symbol column shown in FIG. 32 is selected. When the ratio to the payout is 3 times, the third symbol row shown in FIG. 33 is selected. When the magnification with respect to the payout is four, the fourth symbol row shown in FIG. 34 is selected. When the payout rate is 5 times, the fifth symbol column shown in FIG. 35 is selected. When the magnification with respect to the payout is 10, the sixth symbol row shown in FIG. 36 is selected.

  As described above, when the magnification is 1, the number of JP is one, when the magnification is 2, the number of JP is 2, and when the magnification is 3, When the magnification is 4 times, the number of JPs is 4. When the magnification is 5 times, the number of JPs is 5. When the magnification is 10 times, the number is JP. The number of is 10. As described above, the jackpot reel band 3jp is configured such that the number of JPs of the jackpot reel band 3jp (second type symbol column) increases as the payout ratio increases.

  When the “4 WAYS” button 40 is operated, the symbol string shown in FIG. 37 is selected. When the “16 WAYS” button 41 is operated, the symbol string shown in FIG. 38 is selected. When the “64 WAYS” button 42 is operated, the symbol string shown in FIG. 39 is selected. When the “256 WAYS” button 43 is operated, the symbol string shown in FIG. 40 is selected. When the “1024 WAYS” button 44 is operated, the symbol string shown in FIG. 41 is selected.

  As described above, when the number of BETs is 1, the number of JPs is 2 in total, and when the number of BETs is 10, the number of JPs is 11 in total, and when the number of BETs is 20. The total number of JPs is 12, when the number of BETs is 30, the number of JPs is 13 in total, and when the number of BETs is 50, the number of JPs is 15 in total. . As described above, the jackpot reel band 3jp is configured so that the number of JPs of the jackpot reel band 3jp (second-type symbol column) increases as the BET increases.

  By the processing of steps S4417 and S4419, three random numbers for symbol determination of the reel band 3jp for jackpot in the base game mode are extracted, and the base game mode shown in FIG. 31 to FIG. 36 and FIG. 37 to FIG. Referring to the jackpot reel band, one symbol is determined as a stop scheduled symbol for each of the three jackpot reel bands 3jp-a, 3jp-c, and 3jp-e. In the present embodiment, the three scheduled stop symbols are determined with equal probability.

  By the process of step S4419, three stop scheduled symbols corresponding to each of the three jackpot reel bands 3jp-a, 3jp-c, and 3jp-e are determined. Three jackpot reel bands 3jp-a, 3jp-c, 3jp-e so that the determined three symbols to be stopped stop at the reference position of the symbol matrix (upper middle stage of the symbol display area 141d). Each is controlled to stop (see step S4917 in FIG. 49).

  Next, the main CPU 71 stores the determined stop symbols of the determined three jackpot reel strips 3jp-a, 3jp-c, and 3jp-e in the symbol storage area provided in the RAM 73 (step). S4421).

<Base game mode symbol display control processing>
FIG. 45 is a flowchart showing a subroutine of symbol display control processing in the base game mode.

  As described above, in the base game mode, the five video reels 3a, 3b, 3c, 3d, and 3e have five normal reel bands 3n-a to 3n-e and three jackpot reels. It has bands 3jp-a, 3jp-c, and 3jp-e.

  Specifically, the video reel 3a is displayed by superimposing a normal reel band 3n-a and a jackpot reel band 3jp-a. Only the normal reel band 3n-b is displayed on the video reel 3b. The video reel 3c is displayed by superimposing a normal reel band 3n-c and a jackpot reel band 3jp-c. Only the normal reel band 3n-d is displayed on the video reel 3d. The video reel 3e is displayed by superimposing a normal reel band 3n-a and a jackpot reel band 3jp-e.

  First, the main CPU 71 starts scrolling symbols in the symbol display area 141d of the lower display device 141 by superimposing the normal reel band 3n in the base game mode and the reel band 3jp for jackpot (step S4511). ).

  Next, the main CPU 71 determines whether or not the time until all of the five normal reel bands 3n-a to 3n-e in the base game mode are longer than a predetermined time (step S4513). The predetermined time is a time for defining the maximum time of the unit game.

  In step S4513, whether or not to move the symbol is determined based on the time until five symbols to be stopped in the normal reel bands 3n-a to 3n-e are stopped and displayed (rearranged) in the symbol display area 141d. showed that. In addition, instead of the determination process in step S4513, the number of symbols until five stop scheduled symbols of the normal reel bands 3n-a to 3n-e are stopped and displayed (rearranged) in the symbol display area 141d is determined. It can also be determined by whether or not the predetermined number is exceeded.

  When the main CPU 71 determines that the time until all of the five normal reel bands 3n-a to 3n-e in the base game mode are longer than a predetermined time, the main CPU 71 rewrites the symbols including the symbols to be stopped and The reel bands 3n-a to 3n-e are reconfigured (step S4515). By rewriting the symbols, the symbols in the symbol storage area of the RAM 73 are rewritten.

  Further, instead of the determination processing in step S4513 described above, the number of symbols until five stop scheduled symbols of the normal reel bands 3n-a to 3n-e are stopped and displayed (rearranged) in the symbol display area 141d. When it is determined that the number exceeds the predetermined number, the normal reel bands 3n-a to 3n-e can be reconfigured by rewriting the symbols including the symbols to be stopped by the process of step S4515.

  FIG. 1D is a diagram showing an outline of symbol rewriting. In FIG. 1D, the first symbol columns are normal reel bands 3n-a to 3n-e. The first symbol sequence on the left side of FIG. 1D shows a state immediately before rewriting, and the first symbol sequence on the right side shows a state immediately before rewriting.

  The symbol G in the first symbol row in FIG. 1D moves to P3 on the downstream side of the scroll as shown by the arrow X by rewriting. As indicated by the broken line in FIG. 1D, the symbol G is the leading symbol of movement, and a plurality of symbols after the symbol G move together with the symbol G. As described above, the first symbol and the plurality of symbols that are upstream from the first symbol are moved to the downstream position, so that the first symbol string ( Reconfigure the normal reel bands 3n-a to 3n-e).

  In this way, the five scheduled stop symbols can be stopped and displayed in the symbol display area 141d within a predetermined time. By moving the symbol to a position close to the lower display device 141, the moved symbol can be immediately displayed on the symbol display device by scrolling the symbol, and the time until the symbol rearrangement is prolonged. However, by shortening the scrolling time, the time required for the unit game can be adjusted to be constant.

  Next, the main CPU 71 determines whether or not the time until all the three jackpot reel strips 3jp-a, 3jp-c, and 3jp-e in the base game mode are longer than a predetermined time. (Step S4517). Similar to the determination in step S4513, the predetermined time is a time for defining the maximum time of the unit game.

  In step S4517, it is determined whether or not to move the symbols until the three stop scheduled symbols of the jackpot reel bands 3jp-a, 3jp-c, and 3jp-e are stopped (rearranged) in the symbol display area 141d. The case of judging by the time of was shown. In addition, instead of the determination process in step S4517, the three stop scheduled symbols of the jackpot reel bands 3jp-a, 3jp-c, and 3jp-e are stopped until they are stopped and displayed (rearranged) in the symbol display area 141d. It can also be determined by whether or not the number of symbols in between exceeds a predetermined number.

  When the main CPU 71 determines that the time until all the three jackpot reel bands 3jp-a, 3jp-c, and 3jp-e in the base game mode are longer than a predetermined time, the main CPU 71 The included symbols are rewritten to reconfigure the jackpot reel band 3jp (step S4519). By rewriting the symbols, the symbols in the symbol storage area of the RAM 73 are rewritten.

  Further, instead of the determination processing in step S4517 described above, the three stop scheduled symbols of the jackpot reel strips 3jp-a, 3jp-c, and 3jp-e are stopped and displayed (rearranged) in the symbol display area 141d. Similarly, when it is determined that the number of symbols in between exceeds the predetermined number, the jackpot reel band 3jp can be reconfigured by rewriting the symbols including the symbols to be stopped by the processing in step S4519. .

  In FIG. 1D, the second symbol row is a jackpot reel band 3jp-a, 3jp-c, 3jp-e. The second symbol string on the left side of FIG. 1D shows a state immediately before rewriting, and the second symbol string on the right side shows a state immediately before rewriting.

  Symbol 2 in the second symbol row in FIG. 1D moves to P3 on the downstream side of the scroll as shown by arrow Y by rewriting. As indicated by a broken line in FIG. 1D, the symbol 2 is the leading symbol of movement, and a plurality of symbols after the symbol 2 move together with the symbol 2. In this way, the leading symbol and a plurality of symbols following the leading symbol upstream are moved to the downstream position, so that the leading symbol and the second type symbol string ( The reel strips 3jack-a, 3jp-c, 3jp-e) for the jackpot are reconfigured.

  Next, the main CPU 71 stops a predetermined video reel among the five video reels 3a to 3e based on the symbol storage area (step S4521). The video reel to be stopped and the stop timing are determined by various parameters for production.

  Next, the main CPU 71 determines whether or not all of the five video reels 3a to 3e have been stopped (step S4523). If it is determined that all the five video reels 3a to 3e are not stopped, the process returns to step S4521.

  As described above, the five video reels 3a to 3e have the normal reel band 3n and the jackpot reel band 3jp. In the stop control in step S4521, the normal reel band 3n and the jackpot reel band 3jp are controlled to stop simultaneously.

  Specifically, when the video reel 3a is stopped, both the normal reel band 3n-a and the jackpot reel band 3jp-a are displayed to be stopped simultaneously. When the video reel 3c is stopped, both the normal reel band 3n-c and the jackpot reel band 3jp-c are displayed to be stopped simultaneously. When the video reel 3e is stopped, both the normal reel band 3n-a and the jackpot reel band 3jp-e are displayed to be stopped simultaneously.

  Since the video reel 3b has only the normal reel band 3n-b, the normal reel band 3n-b may be stopped and displayed. Similarly, since the video reel 3d has only the normal reel band 3n-d, the normal reel band 3n-d may be stopped and displayed.

  When the main CPU 71 determines that all of the five video reels 3a to 3e are stopped in the determination processing in step S4523, the main CPU 71 stores all the symbols rearranged in the symbol display area 141d in the RAM 73 (step S4525). This subroutine is finished. As described above, a total of 20 symbols are rearranged in the symbol display area 141d, and the RAM 73 stores 20 symbols.

  In the present embodiment, the main CPU 71 controls the scrolling speed, direction, time, and the like of the five video reels 3a to 3e from the start to the stop of the scrolling of the five video reels 3a to 3e. Predictive and reach production can be executed.

<Payout number determination process>
FIG. 46 is a flowchart showing a subroutine of payout amount determination processing.

  First, the main CPU 71 refers to the payout table shown in FIG. 10 and searches for a winning pattern based on symbols arranged in the normal reel band 3n and rearranged in the symbol display area 141d. (Step S4611). All the rearranged symbols are stored in the RAM 73 by the process of step S4525.

  Next, the main CPU 71 determines whether or not a winning pattern is established (step S4613).

  In the slot machine 10 of the present embodiment, no payline is formed, and a winning pattern is determined for an activated stop position. FEATURE is determined for all stop positions regardless of validation or invalidation.

  If the main CPU 71 determines in step S4613 that the winning pattern has been established, the main CPU 71 refers to the symbol storage area and the payout table (FIG. 10), based on the payout and the BET amount corresponding to the winning pattern. A payout amount is determined (step S4615).

  Next, the main CPU 71 stores the determined payout amount in a payout amount counter in the payout amount storage area (step S4617).

  Since the normal reel bands 3n-a to 3n-e are displayed in both the base game mode and the free game mode, the processes in steps S4611 to S4617 are executed in these two game modes.

  Next, the main CPU 71 determines whether or not the game mode is the base game mode (step S4619).

  When the main CPU 71 determines that the game mode is not the base game mode, the main CPU 71 immediately ends this subroutine.

  When the main CPU 71 determines that the game mode is the base game mode, the main CPU 71 refers to the payout table shown in FIG. 10 and is a symbol arranged in the jackpot reel band 3jp, and is displayed again in the symbol display area 141d. A winning pattern is searched based on the arranged symbols (step S4621). All the rearranged symbols are stored in the RAM 73 by the process of step S4525.

  Next, the main CPU 71 determines whether or not a winning pattern has been established (step S4623). JP is arranged in the jackpot reel strip 3jp, and the determination in step S4623 is a process of determining whether or not the jackpot has been triggered. JP is determined for all stop positions, regardless of whether the stop positions are valid or invalid.

  Next, when the winning pattern is established, the main CPU 71 refers to the payout table (FIG. 10) and determines the payout amount based on the BET amount (step S4625).

  Next, the main CPU 71 stores the determined payout amount in a payout number counter in the payout number storage area (step S4627).

  Next, the main CPU 71 calculates the total amount by adding the cumulative amount accumulated in the process of step S4224 and the progressive initial amount (step S4629).

  Next, the main CPU 71 stores the total amount in the payout number counter in the payout number storage area (step S4631).

  Next, the main CPU 71 initializes the accumulated amount to zero (step S4633), and ends this subroutine. In this way, when the jackpot is triggered and a payout is awarded, the accumulated amount is initialized.

  The processes in steps S4625 to S4633 described above are executed only in the base game mode. Jackpots are triggered only in the base game mode.

  When the main CPU 71 determines in step S4623 that the winning pattern is not established, the main CPU 71 immediately ends this subroutine.

<Free game mode processing>
FIG. 47 is a flowchart showing a subroutine of free game mode processing.

  The free game is a slot game (unit game) similar to the game in the base game mode. In the free game mode, the slot game can be started without making a bet.

  In the free game mode, a reel band dedicated to the free game mode is used (FIGS. 21 to 30). In the first 8 unit games, when 3 FEATUREs appear, the free game mode is retriggered and 8 unit games are added.

  First, the main CPU 71 sets 10 as the number of games (step S4711).

  Next, the main CPU 71 executes an effect at the start of the free game (step S4713). This allows the player to visually recognize that the free game mode has started.

  Next, the main CPU 71 performs an initialization process at the end of one game (step S4715). For example, unnecessary data is cleared for each game in the work area of the RAM 73, such as symbols determined by lottery.

  Next, the main CPU 71 calls and executes a subroutine of symbol lottery processing for the free game mode shown in FIG. 48 (step S4717). With this process, the to-be-stopped symbol is determined based on the symbol determination random value.

  Next, the main CPU 71 conducts effect content start processing (step S4719). In the process of step S4719, the main CPU 71 extracts a random number for determining the effect, determines any of a plurality of predetermined effect contents by lottery, and executes the effect contents at the timing of the determined effect content. . For example, control is performed such as displaying an effect video on the upper display device 131, outputting sound from the speaker 112, turning on a lamp (not shown), or performing effect processing on the lamp.

  Next, the main CPU 71 conducts symbol display control processing for the free game mode shown in FIG. 49 (step S4721). In this process, scrolling of the five video reels 3a to 3e (five reel bands) is started, and the to-be-stopped symbol determined in the symbol lottery process in step S4717 is stopped at a predetermined reference position.

  Next, the main CPU 71 conducts a payout amount determination process shown in FIG. 46 (step S4723). In this process, it is determined whether or not the winning pattern of the payout table (see FIG. 10) is established by the rearranged symbols. The number of payouts is determined based on the payout table (see FIG. 10) according to the winning pattern and stored in a payout number storage area (payout number counter) provided in the RAM 73.

  Next, the main CPU 71 subtracts 1 from the number of games (step S4725).

  Next, the main CPU 71 determines whether or not the free game mode has been retriggered (step S4727). Specifically, it is determined whether or not a FEATURE winning pattern is established.

  When determining that the retrigger in the free game mode has been established, the main CPU 71 adds 10 to the number of games (step S4729), and returns the process to step S4715.

  When determining that the free game mode retrigger is not established, the main CPU 71 determines whether or not the number of games is greater than 0 (step S4731).

  When determining that the number of games is greater than 0, the main CPU 71 returns the process to step S4715.

  When the main CPU 71 determines that the number of games is 0 or less, the main CPU 71 ends the present subroutine.

<Free game mode symbol lottery processing>
FIG. 48 is a flowchart showing a subroutine of symbol lottery processing.

  In the free game mode, only the normal reel band 3n is displayed, and the jackpot reel band 3jp is not displayed. Therefore, the symbols to be stopped are determined for each of the five normal reel bands 3n-a, 3n-b, 3n-c, 3n-d, and 3n-e.

  First, the main CPU 71 extracts five random number values for determining symbols of the normal reel band in the free game mode (step S4811).

  Next, the main CPU 71 refers to the normal reel bands (symbol determination table) in the free game mode from the five random number values, and the normal reel bands 3n-a, 3n-b, 3n-c, 3n-d. , 3ne-e stop scheduled symbols are determined by lottery (step S4813).

  The process of step S4813 is a process of determining five symbols to be stopped with reference to the normal reel band in the free game mode. In the present embodiment, the normal reel band in the free game mode is the table shown in FIGS.

  When the “4 WAYS” button 40 is operated, the symbol strings shown in FIGS. 21 and 22 are selected. When the “16 WAYS” button 41 is operated, the symbol strings shown in FIGS. 23 and 24 are selected. When the “64 WAYS” button 42 is operated, the symbol strings shown in FIGS. 25 and 26 are selected. When the “256 WAYS” button 43 is operated, the symbol strings shown in FIGS. 27 and 28 are selected. When the “1024 WAYS” button 44 is operated, the symbol strings shown in FIGS. 29 and 30 are selected.

  By the processing of steps S4811 and S4813, five random numbers for symbol determination of the normal reel band in the free game mode are extracted, and referring to the normal reel band in the free game mode shown in FIGS. One symbol is determined as a scheduled stop symbol for each of the five normal reel bands 3n-a to 3n-e. In the present embodiment, the five scheduled stop symbols are determined with equal probability.

  By the process of step S4813, five stop scheduled symbols corresponding to each of the five normal reel bands 3n-a to 3n-e are determined. Each of the five normal reel bands 3n-a to 3n-e is controlled to stop so that the determined five symbols to be stopped stop at the reference position of the symbol matrix (upper and middle stages of the symbol display area 141d). (See step S4917 in FIG. 49).

  Next, the main CPU 71 stores the determined to-be stopped symbols of the determined five normal reel bands 3n-a to 3n-e in the symbol storage area provided in the RAM 73 (step S4815).

<Free game mode symbol display control processing>
FIG. 49 is a flowchart showing a subroutine of free game mode symbol display control processing.

  As described above, in the free game mode, the five video reels 3a, 3b, 3c, 3d, 3e have only five normal reel bands 3n-a to 3n-e.

  First, the main CPU 71 starts scrolling the symbols of the normal reel band 3n in the free game mode in the symbol display area 141d of the lower display device 141 (step S4911).

  Next, the main CPU 71 determines whether or not the time until all of the five normal reel bands 3n-a to 3n-e in the free game mode are longer than a predetermined time (step S4913). The predetermined time is a time for defining the maximum time of the unit game.

  When the main CPU 71 determines that the time until all of the five normal reel bands 3n-a to 3n-e in the free game mode are stopped is longer than a predetermined time, the main CPU 71 rewrites the symbols including the symbols to be stopped normally. The reel bands 3n-a to 3n-e are reconfigured (step S4915). By rewriting the symbols, the symbols in the symbol storage area of the RAM 73 are rewritten.

  FIG. 1D is a diagram showing an outline of symbol rewriting. Similar to the base game mode, in FIG. 1D, the first symbol columns are the normal reel bands 3n-a to 3n-e. The first symbol sequence on the left side of FIG. 1D shows a state immediately before rewriting, and the first symbol sequence on the right side shows a state immediately before rewriting.

  The symbol G in the first symbol row in FIG. 1D moves to P3 on the downstream side of the scroll as shown by the arrow X by rewriting. As indicated by the broken line in FIG. 1D, the symbol G is the leading symbol of movement, and a plurality of symbols after the symbol G move together with the symbol G. As described above, the first symbol and the plurality of symbols that are upstream from the first symbol are moved to the downstream position, so that the first symbol string ( Reconfigure the normal reel bands 3n-a to 3n-e).

  In this way, the five scheduled stop symbols can be stopped and displayed in the symbol display area 141d within a predetermined time. By moving the symbol to a position close to the lower display device 141, the moved symbol can be immediately displayed on the symbol display device by scrolling the symbol, and the time until the symbol rearrangement is prolonged. However, by shortening the scrolling time, the time required for the unit game can be adjusted to be constant.

  In the free game mode, unlike the base game mode, the jackpot reel band 3jp is not displayed, and the symbol of the jackpot reel band 3jp is not rewritten.

  Next, the main CPU 71 stops a predetermined video reel among the five video reels 3a to 3e based on the symbol storage area (step S4917). The video reel to be stopped and the stop timing are determined by various parameters for production.

  Next, the main CPU 71 determines whether or not all of the five video reels 3a to 3e have been stopped (step S4919). If it is determined that all of the five video reels 3a to 3e are not stopped, the process returns to step S4917.

  When the main CPU 71 determines that all of the five video reels 3a to 3e are stopped in the determination processing in step S4919, the main CPU 71 stores all the symbols rearranged in the symbol display area 141d in the RAM 73 (step S4921). This subroutine is finished. As described above, a total of 20 symbols are rearranged in the symbol display area 141d, and the RAM 73 stores 20 symbols.

  In the present embodiment, the main CPU 71 controls the scrolling speed, direction, time, and the like of the five video reels 3a to 3e from the start to the stop of the scrolling of the five video reels 3a to 3e. Predictive and reach production can be executed.

<< Jackpot Game Mode >>
The slot machine 10 of the present embodiment has four types of stand-alone jackpots. The four types of jackpots are GRAND, MAJOR, MINOR, and MINI. By the game in the jackpot game mode, the player can acquire a jackpot of GRAND, MAJOR, MINOR, or MINI. A payout corresponding to the type of jackpot acquired is paid out.

  When three JPs appear in the unit game in the base game mode, the base game mode is shifted to the jackpot game mode.

  JP appears only in the base game mode, and does not appear in the free game mode. As shown in FIG. 31 to FIG. 36 and FIG. 37 to FIG. 41, JP is arranged only on the reel band 3jp for jackpot. Since the jackpot reel band 3jp is overlapped with the normal reel band 3n and the symbols are displayed, JP may overlap all symbols constituting the reel band 3n. Accordingly, when three JPs appear and three FEATUREs appear, the free game mode is triggered simultaneously with triggering the jackpot.

<Outline of Jackpot Game>
The jackpot game of the slot machine 10 of the present embodiment is a pick game in which a player selects options.

  The progress of the jackpot game will be described with reference to FIGS. 53a to 55b. In each of FIGS. 53 a to 55 b, the upper side is an image displayed on the upper display device 131 and the lower side is an image displayed on the lower display device 141.

  FIG. 53a is an image displayed on the upper display device 131 and the lower display device 141 when the jackpot is triggered in the base game mode. The upper display device 131 displays the total amount of jackpots at that time according to the type of jackpot. The lower display device 141 displays a normal reel band 3n symbol and a jackpot reel band 3jp symbol. In FIG. 53a, symbols are omitted.

  Subsequently, as shown in FIG. 53b, the upper display device 131 and the lower display device 141 once erase the image and darken it. It is possible to make the player recognize that the game mode is switched.

  Next, when the mode shifts to the jackpot game mode, the image shown in FIG. 54a is displayed. As shown in FIG. 54a, 14 options having a cubic shape are displayed. In the jackpot game, the player can select one option at a time. Hereinafter, the option is referred to as a box.

  As shown in FIG. 54b, a square cursor for selecting a box is displayed. The cursor is displayed around the box. The player can move the cursor by operating the “BET × 1” button 34 to the “BET × 5” button 39. The player can select the box surrounded by the cursor by operating the spin button 46.

  As described above, the player can acquire any one type of jackpot among GRAND, MAJOR, MINOR, and MINI in the jackpot game. The types of jackpots that can be acquired by the player are determined by jackpot lottery processing at the time of transition to the jackpot game mode. The type of jackpot is selected by the jackpot lottery process and is not selected by the player.

  The jackpot game is a game for acquiring one type of jackpot determined by the jackpot lottery process when a player selects boxes one by one and satisfies an end condition.

  When the player selects one box, an icon is displayed instead of the box. The types of icons correspond to GRAND, MAJOR, MINOR, and MINI. Hereinafter, an icon corresponding to GRAND is referred to as a GRAND icon, an icon corresponding to MAJOR is referred to as a MAJOR icon, an icon corresponding to MINOR is referred to as a MINOR icon, and an icon corresponding to MINI is referred to as a MINI icon.

  There are four GRAND icons, MAJOR icons, MINOR icons, and MINI icons. As for the MINOR icon and the MINI icon, one icon is displayed for one box. As for the GRAND icon and the MAJOR icon, there are a case where one icon is displayed for one box and a case where two icons are displayed for one box.

  When the player selects one box, icon lottery processing is executed, the type and number of icons are determined, and the determined type and number of icons are displayed instead of the box. The type and number of icons are determined by the icon lottery process so as to match the jackpot determined by the jackpot lottery process. The player's selection operation is a trigger for executing the icon lottery process, and the type and number of icons cannot be determined by the player.

  As shown in FIG. 55a, the end condition is satisfied when four icons corresponding to the jackpot determined in the jackpot lottery process are prepared. By satisfying the end condition, the jackpot is acquired and the jackpot game mode is ended. In a single jackpot game mode, you get only one type of jackpot. The player can select a box until one type of jackpot determined by the jackpot lottery process is obtained.

  When the end condition is satisfied, as shown in FIG. 55b, the type of the jackpot acquired is displayed, and the total amount of jackpots is displayed as the amount of acquisition. Thereafter, the jackpot game mode ends and the base game mode is restored.

<Jackpot game mode processing>
FIG. 50 is a flowchart showing a subroutine of jackpot game mode processing.

  First, the main CPU 71 extracts a random number for jackpot lottery processing (step S5011).

  Next, the main CPU 71 determines the type of jackpot from the random number value for jackpot lottery processing (step S5013). The processing of steps S5011 and S5013 is jackpot lottery processing. The player can acquire one type of jackpot determined by the jackpot lottery process. As described above, the jackpot that can be acquired by the player is determined regardless of the operation of the player.

  In the jackpot lottery process, GRAND is won with a probability of 500 / 3,443,698, MAJOR is won with a probability of 20,000 / 3,443,698, and MINOR is 420,000 / 3,443. , 698, and MINI wins with a probability of 3,003, 198/3, 443, 698 (for example, in the case of SC01 shown in FIG. 57).

  As shown in FIG. 57, the relationship between GRAND JACKPOT, MAJOR JACKPOT, MINOR JACKPOT, MINI JACKPOT, and SC01 to SC08 is defined. As described above, the jackpot winning probability is defined according to the type of jackpot and the setting combination.

  Next, the main CPU 71 initializes the number of display icons to zero for each type of icon (step S5015). The number of display icons is the number of icons displayed in place of the box by the player's selection operation. The number of display icons is processed for each of the GRAND icon, MAJOR icon, MINOR icon, and MINI icon.

  The process in step S5015 is a process for initializing the number of displayed GRAND icons, the number of displayed GRAND icons, the number of displayed GRAND icons, and the number of displayed GRAND icons.

  Next, the main CPU 71 extracts random numbers for the advance mode lottery process (step S5017).

  Next, the main CPU 71 determines the progression mode from the random number value for the progression mode lottery process (step S5019). The processes in steps S5017 and S5019 are a progress mode lottery process.

  There are two types of progress modes, a random mode and a scenario mode. One mode of the random mode and the scenario mode is determined by the progress mode lottery process. The decision between the random mode and the scenario mode may be selected by the player's operation, or may be set in advance by the administrator of the slot machine 10.

  In the random mode, icons are randomly determined by icon lottery processing. The player can select a box from a minimum of 3 times to a maximum of 11 times. Each time the player selects a box, an icon lottery process is executed and the icon is determined at random.

  As described above, the types of jackpots that a player can acquire are determined in advance. The icon lottery process is a process for determining an icon at random, but the icon is determined by the icon lottery process so as to match the type of the jackpot that has already been determined. The icon lottery process will be described later.

  Also, in the scenario mode, the jackpot game is advanced according to the scenario pattern defined in advance, and by proceeding along the scenario pattern, it is felt that a high payout jackpot can be obtained and the player's expectation is increased. I can talk.

  In the scenario mode, first, three GRAND icons and three MAJOR icons are always aligned. In this way, it can be expected that a GRAND or MAJOR jackpot can be obtained. Thereafter, as in the random mode, an icon is determined by icon lottery processing. The icon lottery process is performed from a minimum of 5 times to a maximum of 11 times.

  FIG. 58 is a table showing scenario patterns. No. 1-No. Twenty-four 24 scenario patterns are defined in advance and stored in the ROM 72. Any one scenario pattern is selected by the scenario lottery process, and the jackpot game is advanced along the selected scenario pattern.

  Next, the main CPU 71 determines whether or not it is a random mode (step S5021).

  When determining that the mode is the random mode, the main CPU 71 calls and executes a subroutine of the random mode process shown in FIG. 51 (step S5023).

  When determining that the mode is not the random mode, the main CPU 71 calls and executes a subroutine of the scenario mode process shown in FIG. 52 (step S5025).

  After executing the processing of step S5023 or S5025, the main CPU 71 displays an image indicating that a jackpot has been acquired (step S5027).

  Next, the main CPU 71 determines a payout according to the acquired jackpot (step S5029), and ends this subroutine.

<Random mode processing>
FIG. 51 is a flowchart showing a subroutine of random mode processing.

  First, the main CPU 71 determines whether or not the player has selected a box (step S5111).

  If the main CPU 71 determines that the player has not selected a box, the main CPU 71 returns the process to step S5111.

  When determining that the player has selected the box, the main CPU 71 extracts a random number for icon lottery processing (step S5113).

  Next, the main CPU 71 determines icons except for the lottery exclusion icon (step S5115). The process of steps S5113 and S5115 is an icon lottery process.

  When four icons corresponding to the jackpot determined by the jackpot lottery process are prepared, the end condition is satisfied. By satisfying the end condition, the player acquires the jackpot.

  The icon is determined by a lottery process. Depending on how the lottery process is performed, there may be four icons corresponding to jackpots that are not determined in the jackpot lottery process. For example, when MINI is determined as a jackpot by the jackpot lottery process and four GRAND icons are prepared by the icon lottery process, the result of the icon lottery process does not match the result of the jackpot lottery process.

  For this reason, in the icon lottery process, it is necessary to determine an icon so as to match the type of jackpot determined in the jackpot lottery process. An icon that should not be selected in the icon lottery process is determined as a lottery exclusion icon, and the icon lottery process is executed. In this way, since the lottery exclusion icon is not selected in the icon lottery process, it is possible to prevent four icons corresponding to the jackpots not determined in the jackpot lottery process from being prepared. The lottery exclusion icon will be described later.

  Next, the main CPU 71 displays the icon determined by the icon lottery process instead of the box (step S5117).

  Next, the main CPU 71 adds 1 to the number of display icons corresponding to the type of icon determined in the icon lottery process (step S5119).

  As described above, the number of display icons is processed for each of the GRAND icon, MAJOR icon, MINOR icon, and MINI icon. The process of step S5119 is performed as follows. When the GRAND icon is determined by the icon lottery process, 1 is added to the number of display icons corresponding to the GRAND icon. When the MAJOR icon is determined by the icon lottery process, 1 is added to the number of display icons corresponding to the MAJOR icon. When the MINOR icon is determined by the icon lottery process, 1 is added to the number of display icons corresponding to the MINOR icon. When the MINI icon is determined by the icon lottery process, 1 is added to the number of display icons corresponding to the MINI icon.

  Next, the main CPU 71 determines whether or not the icon type determined in the icon lottery process matches the jackpot type determined in the jackpot lottery process (step S5121).

  If the main CPU 71 determines in step S5121 that the icon type determined in the icon lottery process matches the jackpot type determined in the jackpot lottery process, the main CPU 71 determines whether or not the number of displayed icons is four. Is determined (step S5123). That is, it is determined whether an end condition is satisfied.

  When the main CPU 71 determines in the determination process of step S5123 that the number of display icons is 4, that is, the end condition is satisfied, the main CPU 71 ends the present subroutine.

  When the main CPU 71 determines in the determination process of step S5123 that the number of display icons is not four, that is, the end condition is not satisfied, the process returns to step S5111.

  If the main CPU 71 determines in step S5121 that the icon type determined in the icon lottery process does not match the jackpot type determined in the jackpot lottery process, whether the lottery exclusion condition is satisfied. Is determined (step S5125).

  The lottery exclusion condition is a condition for determining whether or not to make a lottery exclusion icon. An icon that satisfies the lottery exclusion condition is a lottery exclusion icon.

  As described above, the end condition is satisfied when four icons corresponding to the jackpot determined in the jackpot lottery process are prepared. For this reason, it is necessary to prevent four icons corresponding to jackpots not determined in the jackpot lottery process from being prepared.

  This will be specifically described below.

  When GRAND is determined as a jackpot in the jackpot lottery process, the end condition is satisfied when four GRAND icons are prepared. For this reason, it is necessary to prevent four icons other than the GRAND icon from being arranged. The lottery exclusion condition when GRAND is determined in the jackpot lottery process is that two MAJOR icons are arranged, three MINOR icons are arranged, and three MINI icons are arranged.

  If the two MAJOR icons are determined and the two MAJOR icons are determined by the player's selection operation, the MAJOR end condition is satisfied. In order to eliminate this, a lottery exclusion condition is that two MAJOR icons are prepared. As described above, in the MAJOR icon, two icons may be displayed for one box.

  When one MINOR icon is determined by a player's selection operation in a state where three MINOR icons are aligned, the MINOR termination condition is satisfied. In order to eliminate this, a lottery exclusion condition is that three MINOR icons are prepared.

  Similarly, when one MINI icon is determined by the player's selection operation in a state where three MINI icons are aligned, the MINI end condition is satisfied. In order to eliminate this, a lottery exclusion condition is that three MINI icons are prepared.

  When MAJOR is determined as a jackpot in the jackpot lottery process, the end condition is satisfied when four MAJOR icons are arranged. For this reason, it is necessary to prevent four icons other than the MAJOR icon from being arranged. The lottery exclusion condition when MAJOR is determined in the jackpot lottery process is that two GRAND icons are arranged, three MINOR icons are arranged, and three MINI icons are arranged.

  If two GRAND icons are determined by the player's selection operation in a state where the two GRAND icons are aligned, the GRAND end condition is satisfied. In order to eliminate this, a lottery exclusion condition is that two GRAND icons are prepared. As described above, in the GRAND icon, two icons may be displayed for one box.

  Similarly, when MINOR is determined as a jackpot in the jackpot lottery process, the end condition is satisfied when four MINOR icons are prepared. For this reason, it is necessary to prevent four icons other than the MINOR icon from being arranged. The lottery exclusion condition when MINOR is determined in the jackpot lottery process is that two GRAND icons are aligned, two MAJOR icons are aligned, and three MINI icons are aligned.

  When MINI is determined as a jackpot in the jackpot lottery process, the end condition is satisfied when four MINI icons are prepared. For this reason, it is necessary to prevent four icons other than the MINI icon from being arranged. The lottery exclusion condition when MINI is determined in the jackpot lottery process is that two GRAND icons are aligned, two MAJOR icons are aligned, and three MINOR icons are aligned.

  When the main CPU 71 determines in the determination process of step S5125 that the lottery exclusion condition is satisfied, the main CPU 71 determines the icon for which the lottery exclusion condition is satisfied as a lottery exclusion icon (step S5127), and returns the process to step S5111.

  The lottery exclusion icon determined in step S5127 is excluded in the icon determination processing in step S5115 described above, and icon lottery processing is executed. By doing in this way, the result of the icon lottery process can be matched with the result of the jackpot lottery process.

  When the main CPU 71 determines in the determination process of step S5125 that the lottery exclusion condition is not satisfied, the main CPU 71 immediately returns the process to step S5111.

<Scenario mode processing>
FIG. 52 is a flowchart showing a subroutine of scenario mode processing.

  First, the main CPU 71 initializes the number of selections with zero (step S5211). The number of selections is the number of times the player has selected a box.

  Next, the main CPU 71 extracts a random number for scenario lottery processing (step S5213).

  Next, the main CPU 71 determines a scenario from the random value for scenario lottery processing (step S5215). The processes in steps S5213 and S5215 are scenario lottery processes.

  FIG. 58 is a table showing scenario patterns. One scenario pattern is selected from the 24 scenario patterns by the scenario lottery process. As shown in FIG. 58, the weight of each of the 24 scenario patterns is 1, and the 24 scenario patterns are selected with equal probability by the scenario lottery process.

  Each of the 24 scenario patterns in FIG. 58 defines data for determining the first to fourth icons of the jackpot game. By the first to fourth jackpot games, three GRAND icons and three MAJOR icons are always aligned. Thus, by making sure that the three GRAND icons and the three MAJOR icons are aligned at the initial stage of the jackpot game, the player's expectation can be enhanced.

  The fifth and subsequent jackpot games are carried out in the same manner as in the random mode. Therefore, even in the scenario mode, four icons corresponding to the jackpot determined in the jackpot lottery process are finally arranged to satisfy the end condition.

  Next, the main CPU 71 determines whether or not the player has selected a box (step S5217).

  If the main CPU 71 determines that the player has not selected a box, the main CPU 71 returns the process to step S5217.

  When the main CPU 71 determines that the player has selected a box, the main CPU 71 adds 1 to the number of selections (step S5219).

  Next, the main CPU 71 determines whether or not the number of selections is less than 5 (step S5221).

  When determining that the number of selections is not less than 5, the main CPU 71 refers to the scenario pattern determined by the scenario lottery process and determines an icon corresponding to the number of selections (step S5223). That is, when the number of times of the jackpot game is 1st to 4th, an icon is determined along the scenario pattern. By executing the jackpot game up to the fourth time, the three GRAND icons and the three MAJOR icons are always aligned.

  When the main CPU 71 determines in step S5121 that the number of selections is less than 5, the main CPU 71 extracts a random number for icon lottery processing (step S5225).

  Next, the main CPU 71 determines icons except for the lottery exclusion icon (step S5227). The process of steps S5225 and S5227 is an icon lottery process. As described above, the lottery exclusion icon is an icon for matching the result of the icon lottery process with the result of the jackpot lottery process.

  Next, the main CPU 71 displays the icon determined in step S5123 or step S5227 instead of the box (step S5229).

  Next, the main CPU 71 adds 1 to the number of display icons corresponding to the type of icon determined in the icon lottery process (step S5231).

  Step S5231 is the same process as the process of step S5119 described above. When the GRAND icon is determined by the icon lottery process, 1 is added to the number of display icons corresponding to the GRAND icon. When the MAJOR icon is determined by the icon lottery process, 1 is added to the number of display icons corresponding to the MAJOR icon. When the MINOR icon is determined by the icon lottery process, 1 is added to the number of display icons corresponding to the MINOR icon. When the MINI icon is determined by the icon lottery process, 1 is added to the number of display icons corresponding to the MINI icon.

  Next, the main CPU 71 determines whether or not the icon type determined in the icon lottery process matches the jackpot type determined in the jackpot lottery process (step S5233).

  If the main CPU 71 determines in step S5233 that the icon type determined in the icon lottery process matches the jackpot type determined in the jackpot lottery process, the main CPU 71 determines whether or not the number of displayed icons is four. Is determined (step S5235). That is, it is determined whether an end condition is satisfied.

  When the main CPU 71 determines in the determination process of step S5235 that the number of display icons is 4, that is, the end condition is satisfied, the main CPU 71 ends the present subroutine.

  When the main CPU 71 determines in the determination process of step S5235 that the number of display icons is not four, that is, the end condition is not satisfied, the process returns to step S5217.

  If the main CPU 71 determines in step S5233 that the icon type determined in the icon lottery process does not match the jackpot type determined in the jackpot lottery process, whether or not the lottery exclusion condition is satisfied. Is determined (step S5237). The lottery exclusion condition is the same as that described above.

  When the main CPU 71 determines in the determination process of step S5237 that the lottery exclusion condition is satisfied, the main CPU 71 determines the icon that satisfies the lottery exclusion condition as the lottery exclusion icon (step S5239), and returns the process to step S5217.

  The lottery exclusion icon determined in step S5239 is excluded in the icon determination processing in step S5227 described above, and icon lottery processing is executed. By doing in this way, the result of the icon lottery process can be matched with the result of the jackpot lottery process.

  When the main CPU 71 determines in the determination process of step S5237 that the lottery exclusion condition is not satisfied, the main CPU 71 immediately returns the process to step S5217.
