When the symbols are arranged in a predetermined manner, a prize is awarded, and a game value granting means (101, S110) for granting a game value according to the prize awarded, and the prize includes a specific prize (for example, Cherry 1 prize) A game in which a predetermined condition is satisfied (for example, an SB1 game to an SB3 game, an RB inside game) including a cherry 3 prize, an RB prize) (E.g., a normal game), the management means (101) for increasing the possibility of winning the specific prize, and in the storage unit in response to the confirmed expression of the game satisfying the predetermined condition A notification means (101, S111) for notifying a specific winning line set from among the plurality of types of stored winning line sets, wherein the specific winning line set is a game satisfying the predetermined condition. When the arrangement of symbols in a predetermined mode related to winning in the specific prize is stopped on the activated winning line, or when trying to stop, it is a game compared to the case where another winning line group is selected. It is characterized by a winning line group that is advantageous to the player.

In these slot machines, when the expression of a game that increases the possibility of winning a specific prize is confirmed by satisfying a predetermined condition, the game is arranged in a predetermined manner related to winning the specific prize. When the player is stopped or is to be stopped on the activated pay line, a specific pay line group that is advantageous to the player compared to the case where another pay line group is selected is notified. Thereby, the player can know which winning line group is advantageous among a plurality of types of winning line groups in the game of the game.
In addition, in the above-mentioned notification means “notify the winning line group”, not only when the winning line group itself is notified, but also when the winning line group is selected according to the number of bets, Since notifying the winning line group is notifying the fact that the bet number is betted, it is also included.

As an aspect of the slot machine according to the present invention, in each of the plurality of display columns, the symbols constituting the specific prize are arranged on two or more winning lines in a state where the variable display of the plurality of displays is stopped. A game in which a plurality of symbols are arranged as possible, and the management means executes a lottery with a plurality of prizes and disparities as a lottery object, and the predetermined condition is satisfied, and a game in which the predetermined condition is not satisfied Compared to the lottery means (101, S105 to S107) for controlling the lottery so that the winning probability of the specific prize is higher compared to the stop operation means, it corresponds to the stop operation within a predetermined number of frames. Stop control means (1) for stopping the variable display of the plurality of display lines so that the display line is advanced and stopped, and winning is allowed only for the prizes won by the lottery means. 1 and S109), and the specific winning line group (for example, the winning line group consisting of L1, L2, and L3, the winning line group consisting of L1, L4, and L5 shown in FIG. 5, and L1 and L6). And a winning line set consisting of L7) is a predetermined mode related to winning the specific prize (for example, Cherry 1 prize to Cherry 3 prize) in a game (for example, SB1 game to SB3 game) that satisfies the predetermined condition The plurality of types of winning lines that can be made to overlap with the specific prize by simultaneously stopping at a plurality of validated winning lines.
In this aspect, when the expression of a game (for example, SB1 game to SB3 game) that increases the winning probability for a specific prize (for example, Cherry 1 Award to Cherry 3 Award) is determined by satisfying a predetermined condition, The player is notified of a winning line group (a specific winning line group) that allows multiple winnings when the arrangement of symbols in a predetermined manner related to winning a specific prize is stopped on an activated winning line. The Then, the player can enjoy the benefit that by selecting the specific winning line group in the game of the game, the player wins a double prize when winning the specific prize in the game.

  In addition, the prize includes a start prize (for example, an SB prize shown in FIG. 7) for changing the type of game as a game value to be given, and a small prize that a game medium is paid out as a game value to be given. The start prize includes a plurality of individual start prizes (for example, SB1 prize to SB3 prize shown in FIG. 7), and the small role prize includes a plurality of specific small prizes (for example, Cherry 1 prize to Cherry shown in FIG. 7). 3 prizes), the specific prize is the specific small prize, each of the plurality of specific small prizes is associated with each of the plurality of individual start prizes, It is composed of one specific symbol (for example, the “cherry” symbol shown in FIG. 7) and a plurality of arbitrary symbols, and the plurality of specific small role awards are different from each other in display columns in which the specific symbols are stopped. Multiple winning line groups that can be selected by the line validation means Among the plurality of display columns, the symbol stop positions of a plurality of winning lines constituting the set in a specific display column match, and if the set is different, the specific display column is different and the predetermined condition is satisfied. The game is a game used for the next game won in any of the plurality of individual start prizes, and when the lottery means wins each of the plurality of individual start prizes, the individual start won in the next game The lottery is controlled so that the winning probability of the specific small role award corresponding to the award becomes high.

As an aspect of the slot machine according to the present invention, the plurality of winning line groups that can be validated by the winning line validating means include, as the specific winning line group, how the player uses the plurality of stop operating means. A winning line group (for example, a winning line group consisting of L8 to L15 shown in FIG. 16) that enables the plurality of types of winning lines to be awarded to the specific prize (for example, the RB prize shown in FIG. 17) even if operated to It is included.
In this mode, when the expression of a game that is highly likely to win a specific prize is confirmed due to the satisfaction of a predetermined condition, the arrangement of symbols in a predetermined mode related to winning the specific prize is valid in the game of the game. When trying to stop at a particular winning line, the player is informed of a specific winning line set that is 100% winable for the specific prize no matter what timing the player operates the stop operation means. The Then, the player can enjoy the benefit of being able to win 100% of the specific prize by selecting a specific winning line group in the game of the game.

In addition, the prize includes a start prize (for example, an RB prize shown in FIG. 17) for changing the type of game as a game value to be given, and a small prize that a game medium is paid out as a game value to be given. The specific prize is the start prize, and the management means executes a lottery for each game with a plurality of prizes and outliers as lottery targets, and the lottery result indicating the winning of each of the plurality of prizes or the missed prize. When the lottery information indicating the lottery result indicating the lottery result is generated and the lottery information winning the specific prize is generated, the specification from the next game of the game that generated the lottery information won the specific prize to the game winning the specific prize A lottery information indicating that a prize is won is retained, and the game type is changed to a game satisfying a predetermined condition (for example, a game inside the RB) to win the specific prize in each game in the game. The lottery means (101) for increasing the performance as compared with the game in which the predetermined condition is not satisfied, and the display sequence corresponding to the stop operation within a predetermined number of frames from the time when the stop operation means is operated And stop control means (101, S109) for stopping the variable display of the plurality of display rows so as to allow the winning to be permitted only to the prizes that are won by the lottery means.
For example, it is assumed that the above-mentioned “game satisfying predetermined conditions” is an RB inside game. In the RB internal game in which the lottery information indicating that the RB prize (specific prize) is won is held, the RB prize is always won internally, and the winning probability of the RB prize is 100%. The possibility of winning the RB award can be expressed by the probability of winning the RB award x the probability that the symbols that make up the RB role on the active line will stop. It can be said that the possibility of winning the RB prize is higher than that of other games (for example, the base game) in which the above condition is not satisfied.

FIG. 6 is an explanatory diagram showing the flow of game medals in the gaming method of the slot machine 1 according to the first embodiment of the present invention.
(1) Insertion bet processing A game in the slot machine 1 starts when a player inserts a game medal into the medal insertion slot 10 (insertion operation). The CPU 101 selects one winning line group from among a plurality of types of winning line groups according to the player's input operation, and validates the plurality of types of winning lines that constitute the selected winning line group. In this embodiment, when the CPU 101 detects the insertion of a game medal based on the medal insertion signal 160, the CPU 101 selects one winning line group from a plurality of types of winning line groups according to the detected number of game medals (number of BETs). A plurality of types of winning lines constituting the winning line set are selected and activated. For example, when the CPU 101 detects the insertion of the first game medal based on the medal insertion signal 160, the CPU 101 selects a winning line group corresponding to the BET number “1”, and a plurality of types of winnings constituting the winning line group. Activate the line. More specifically, when the CPU 101 detects the insertion of the first game medal, the CPU 101 reads out the management number assigned to the winning line group corresponding to the BET number “1” from the ROM 104 to thereby determine the winning line group. And the first winning line L1, the second winning line L2, and the third winning line L3 constituting the winning line set are activated.

  Further, when the CPU 101 detects the insertion of the second game medal by the medal insertion signal 160, the CPU 101 selects a winning line group corresponding to the “BET” number “2”, and a plurality of types of winnings constituting the winning line group. Activate the line. More specifically, when detecting the insertion of the second game medal, the CPU 101 reads out the management number assigned to the winning line group corresponding to the BET number “2” from the ROM 104 to thereby determine the winning line group. And the first winning line L1, the fourth winning line L4, and the fifth winning line L5 constituting the winning line set are activated.

  Further, when the CPU 101 detects the insertion of the third game medal by the medal insertion signal 160, the CPU 101 selects a winning line group corresponding to the BET number “3”, and a plurality of types of winnings constituting the winning line group. Activate the line. Specifically, when detecting the insertion of the third game medal, the CPU 101 reads out the management number assigned to the winning line set corresponding to the BET number “3” from the ROM 104, thereby determining the winning line set. In other words, the first winning line L1, the sixth winning line L6, and the seventh winning line L7 constituting the winning line group are selected and activated. In the present embodiment, the number of winning lines activated for each game is set to a fixed number (three) regardless of the number of game medals inserted.

(2) Inserted credit processing When a game medal is further inserted, the CPU 101 controls the storage device to store the credit as a credit until the number of inserted medals reaches the credit upper limit value. The CPU 101 electronically stores the number of game medals inserted in the storage device as credits (number of credits). When the number of inserted medals reaches the credit upper limit value, the CPU 101 controls to pay out the game medals inserted thereafter to the medal tray 40.
(3) Storage bet processing In order to start the game, in addition to the above-described insertion operation, the winning line is activated by the player pressing down the bet button 11 (storage bet operation). The CPU 101 selects one winning line group from among a plurality of types of winning line groups in accordance with the player's stored betting operation, and validates the plurality of types of winning lines that make up the selected winning line group. In this embodiment, when the CPU 101 detects the insertion of a game medal based on the bet operation instruction signals 111a to 111c, one winning is selected from a plurality of types of winning line groups according to the detected number of game medals (BET number). A line group is selected, and a plurality of types of winning lines constituting the winning line group are validated. For example, when a bet operation instruction signal 111a detects a press operation of a single bet button, the CPU 101 reduces the number of credits by 1 and selects a winning line set corresponding to the BET number “1”. Each of a plurality of types of winning lines (L1, L2, L3) constituting the winning line set is validated. Further, when the press operation of the two-sheet bet button is detected by the bet operation instruction signal 111b, the CPU 101 reduces the number of credits by two and selects a winning line set corresponding to the BET number “two”. Each of a plurality of types of winning lines (L1, L4, L5) constituting the winning line set is validated. Further, when the pressing operation of the maximum bet button is detected by the bet operation instruction signal 111c, the CPU 101 reduces the number of credits by 3 and selects a winning line set corresponding to the number of BETs “3”. In other words, each of a plurality of types of winning lines (L1, L6, L7) constituting the winning line group is validated. This storage bet operation and the above-described insertion bet operation are simply referred to as a bet operation.

(4) Dividend credit processing When the player depresses the start lever 12, rotation of the three reels R1 to R3 is started, and when the player depresses the stop buttons 13a to 13c, the reel R1 corresponding to each stop button ~ R3 is stopped. When all the reels R1 to R3 are stopped, when a predetermined symbol combination is aligned on the activated winning line, a winning is awarded and a game value determined for each symbol combination (combination) is given. When a game medal is awarded as a game value as a game value, the CPU 101 first controls the game medal to be stored as a credit in the storage device.
(5) Dividend payout process When the number of stored game medals reaches the credit upper limit value in the process of giving a dividend, the CPU 101 controls to pay out the remaining game medals to the medal tray 40. More specifically, the CPU 101 pays out the remaining game medals to the medal tray 40 by driving the medal payout device.
(6) Automatic bet processing When a re-game prize is won as a result of the game, the same number of game medals as the previous game are automatically bet.

(7) Return payout process After the winning line is activated by the bet operation and before the player presses the start lever 12, the player presses the checkout button 14 to drive the medal payout device. As a result, the game medals corresponding to the activated winning line are paid out to the medal tray 40.

<A-3-2: Slot machine awards and roles>
FIG. 7 is an explanatory diagram for explaining the prizes and combinations in the slot machine 1 and shows the configuration of the types of awards and their combinations (combination of symbols). The slot machine 1 wins when a predetermined symbol combination is aligned on the activated pay line, and a small combination to which a maximum payout of 15 medals is awarded based on the number of payouts determined for each combination. There are a prize, a start prize for starting another type of game from the normal game, and a re-game prize that gives a game value that the next game can be performed without a betting operation.

(1) Start Award The RB Award is a start award for starting an RB game, and includes a combination of symbols of “red 7-red 7-red 7” (also referred to as “red 7 role”) as a role. The SB award is composed of three types of SB1 award, SB2 award and SB3 award. The SB1 prize is a start prize for starting the SB1 game, and is composed of a combination of symbols of “red 7-RR” (also referred to as “red 7-R-R combination”) as a combination. The SB2 award is a start prize for starting the SB2 game, and includes a combination of symbols “R-red 7-R” (also referred to as “R-red 7-R combination”) as a combination. The SB3 award is a start prize for starting the SB3 game, and is composed of a combination of symbols “RR-Red 7” (also referred to as “RR-Red 7 role”) as a role.
(2) Small Award The Bell Award is a small role award with 5 medals as a dividend, and is composed of a combination of symbols “Bell-Bell-Bell” (also referred to as “Bell Role”) as a role. The Cherry 1 Award to Cherry 3 Award are small role awards for paying 5 medals each. Each of the Cherry 1 Award to Cherry 3 Award is composed of one “cherry” symbol (“specific symbol”) and a combination of two “ANY” symbols. ANY indicates that any symbol other than cherry can be used. Cherry 1 Award to Cherry 3 Award are different from each other in the reels on which the cherry symbols stop. Hereinafter, the Cherry 1 Award to Cherry 3 Award will be described in detail.

  The Cherry 1 Award is composed of a combination of symbols “CHERRY-ANY-ANY” as a role. This “Ceri-1 Award” is awarded only when the “Cherry” symbols of the left reel R1 are aligned on the winning line. Here, as shown in FIG. 5 (a), the symbol stop positions on the left reel R1 of the first pay line L1, the second pay line L2, and the third pay line L3 all coincide with each other at the middle display position M1. In a game, when the three types of winning lines (L1, L2, L3) are activated and the “cherry” symbol stops at the middle display position M1 of the left reel R1, the three types of winning lines are displayed. At the same time, win the Cherry 1 Award. The simultaneous winning of a combination on a plurality of winning lines in this manner is called a double winning, and it is possible to obtain a payout corresponding to the upper limit of 15 payouts corresponding to the overlapping winning combination. In this case, 15 medals can be obtained as a payout.

  The Cherry 2 Award is composed of a combination of symbols “ANY-Cherry-ANY” as a role. This “Ceri-2 Award” is awarded only when “Cherry” symbols of the middle reel R2 are aligned on the winning line. Here, as shown in FIG. 5 (b), the symbol stop positions on the middle reel R2 of the first pay line L1, the fourth pay line L4, and the fifth pay line L5 all coincide with each other at the middle display position M2. In a game, when the three types of winning lines (L1, L4, L5) are activated and the “cherry” symbol stops at the middle display position M2 of the middle reel R2, the three types of winning lines are displayed. In the above, the second prize is given for the Cherry 2 Award, and 15 medals can be obtained as a dividend.

  Furthermore, the Cherry 3 Award is composed of a combination of symbols “ANY-ANT-Cherry” as a role. The “cherry 3 award” is awarded only when the “cherry symbol” of the right reel R3 is aligned on the winning line. Here, as shown in FIG. 5C, the symbol stop positions on the right reel R3 of the first pay line L1, the sixth pay line L6, and the seventh pay line L7 all coincide with each other at the middle display position M3. Then, in a game, when the three types of winning lines (L1, L6, L7) are activated and the “cherry” symbol stops at the middle display position M3 of the right reel R3, the three types of winning lines In the above, the 3rd Cherry Prize is won and 15 medals can be obtained as a dividend.

(3) Re-play award The re-play award is a re-play award that gives a game value that the next game can be performed without a betting operation, and a combination of symbols “R-R-R” (“R role ”).

(4) 100% Pullable Designs “R” design and “bell design” are the same “R” design and the next “R” on the same reel, as shown in the design layout of FIG. The interval between the symbols, or the interval between the “bell” symbol and the next “bell” symbol, are both arranged within 5 symbols (5 frames). For example, in the middle reel R2, the “R” symbol of symbol number PN = 7 and the “R” symbol of symbol number PN = 10 are separated by three frames. In the slot machine 1, the symbols constituting the prize can be stopped by drawing up to four frames on the winning line by reel stop control. Therefore, no matter what timing the player operates the stop buttons 13a, 13b, 13c by placing the “R” symbol and the “bell” symbol so that the intervals are within 5 frames, It becomes possible to draw the symbol on the line and stop it. Such “R” symbol and “bell” symbol are referred to as 100% retractable symbols. “Bell role” and “R role” are all 100% pullable symbols that make up the combination of the awards. In games where those awards are won, the player can press the stop button at any timing. Even if 13a, 13b, 13c are operated, a prize is always won. Prizes composed of such roles are called prizes that can be awarded 100%.
On the other hand, a prize composed of a symbol that is not a 100% drawable symbol will be displayed on the winning line if the player's reel stop button operation timing is not appropriate, even if the prize is won by an internal lottery. The symbol combination is not complete and the game is not won. The fact that the symbol combinations corresponding to the winning prizes are not complete and cannot be won is called “missing”.

<A-3-3: Explanation of various games in the slot machine>
FIG. 8 is an explanatory diagram showing the types of games played in the slot machine 1. FIG. 8A shows a transition between a plurality of games performed in the slot machine 1.
(1) Start and end of the RB game When the RB prize is won by the internal lottery during the normal game, and the "Red 7 role" for winning the RB prize is established on the winning line, the RB game starts from the next game. Starts. The RB game is played a maximum of 12 times, and when the RB game is won eight times during the execution of the RB game, the RB game is terminated.
(2) RB inside game Even if the RB prize is won by the internal lottery during the normal game, if the “Red 7 role” for winning the RB prize is not established on the winning line, the RB prize will be given after the next game. It becomes an RB inside game in which the winning flag of the RB prize is carried over until the winning “Red 7 role” is established and won. When “Red 7 role” is won in the RB inside game, the RB game starts from the next game.
(3) SB1 game When the SB1 prize is won by an internal lottery during the normal game and a combination of symbols of "Red 7-R-R" is established on the winning line, the SB1 game starts from the next game. . The SB1 game ends with one game.
(4) SB2 game When the SB2 prize is won by internal lottery during the normal game, and the combination of symbols “R-Red 7-R” is established on the winning line and the prize is won, the SB2 game starts from the next game. . The SB2 game ends with one game.
(5) SB3 game While the normal game is being executed, the SB3 prize is won by internal lottery. When the combination of symbols “RR-Red 7” is established on the winning line and the prize is won, the SB3 game starts from the next game. . The SB3 game ends with one game.

  In the slot machine 1, the game type is managed by a game type flag shown in FIG. When the bit 0 of the game type flag is set to “1” as the RB game in-progress flag, it indicates that the RB game is in progress. Show. When bit 2 is set to “1” as the SB2 in-game flag, it indicates that the SB2 game is in progress. Also, when bit 3 is set as “SB3 game flag” and “1” is set, “1” indicates that the SB3 game is in progress, and when bit 4 is set as “RB internal game flag” and “1” is set, the RB internal game is set Shown inside. If any bit indicates “0” without being set, it indicates that a normal game is being played.

<A-4: Operation of slot machine>
Next, details of the overall operation of the slot machine 1 will be described. The CPU 101 performs initialization processing after power-on, and executes the processing of the flowchart shown in FIG.

<A-4-1: 1 game flow>
FIG. 9 is a flowchart showing the contents of the flow of one game. First, the CPU 101 determines based on the medal insertion signal 160 or the bet operation instruction signals 111a to 111c whether or not an insertion bet operation by inserting a medal or a storage bet operation by pressing the bet button 11 has been performed, (S100). If any signal is detected, the CPU 101 validates each of the plurality of winning lines constituting the winning line set corresponding to the number of BETs at that time, proceeds to the next, and starts based on the start operation instruction signal 112 It is determined whether or not a lever operation has been performed, and waits until a signal is detected (S101). When the CPU 101 detects a signal, it determines whether or not a later-described notification image is displayed on the liquid crystal display 30 (S102). When determining that the notification image is displayed, the CPU 101 controls the display control board 100B to delete the notification image (S103). Then, the CPU 101 prohibits the betting operation (S104). Even when the CPU 101 determines in step S102 that the notification image is not displayed, the CPU 101 proceeds to step S104 and prohibits the betting operation. More specifically, the solenoid of the medal selector device is turned off by the medal block signal 161, the passage route of the medal selector device is switched, and the game medal is discharged to the medal tray 40 even when it is inserted from the medal insertion slot 10. Also, bet operation instruction signals 111a to 111c are not accepted.

  Next, the CPU 101 sequentially increments every 10 nanoseconds in the range of 0000H to FFFFH, acquires the counter value from the counter circuit that makes one round in about 1.6 milliseconds via the input / output port 107, and sets it as a random value ( S105). Next, referring to each game type flag, a prize lottery table corresponding to the type of the game is selected (S106). Using the selected prize lottery table, the CPU 101 determines which numerical range set for each category of the prize lottery table the acquired random number value belongs to, and corresponds to the lottery category belonging to the numeric range The lottery information (winning flag) of the winning prize is set (S107). Next, the CPU 101 supplies pulses to the reel drive signals 154a to 154c, and drives the stepping motors sequentially or simultaneously to rotate the three reels (S108). Specifically, the reel drive signals 154a to 154c include a plurality of drive signal lines for exciting a plurality of winding phases, and the reels are supplied by supplying a pulse signal to each drive signal line in a predetermined phase pattern. Rotate.

  Next, the CPU 101 detects that the three reels R1 to R3 have reached a constant rotational speed after all the three reels R1 to R3 have reached a constant rotational speed through an acceleration period of 10 steps. Is used as a reference time, and measurement of the remaining time from the reference time until the automatic stop time elapses is started, and an LED incorporated in the stop button is lit to notify that the stop buttons 13a to 13c can be received. Specifically, it is detected that the pulse width of the reel drive signals 154a to 154c supplied to the drive signal line of the stepping motor is constant, and this detection time is used as a reference time, and counts down to 0 every 2 milliseconds. A value indicating a predetermined automatic stop time (for example, 30 seconds) is set as an initial value of the timer value. At this time, the LED built in the stop button corresponding to each reel is turned on.

  In addition, as a method of detecting that the three reels R1 to R3 have reached a constant rotation speed, after a predetermined number of steps have elapsed from the start of rotation, or after a predetermined time has elapsed from the start of rotation (a predetermined number of interruptions have occurred), A method of assuming that a constant rotational speed has been reached by outputting pulses at regular intervals to the stepping motor, or after a predetermined number of steps have elapsed since the start of rotation, or after a predetermined time has elapsed since the start of rotation (a predetermined number of interruptions have occurred) There is a method of determining that a predetermined rotational speed has been reached when a predetermined time has elapsed, a predetermined number of steps have elapsed, a stepping motor has made one revolution, or an index has been detected. That is, in this embodiment, the time point at which the constant rotational speed is detected is set as the reference time point, but the time point at which it is considered that the constant rotational speed is reached may be set as the reference time point.

  Then, the CPU 101 performs a reel stop process for stopping the three reels R1 to R3 (S109). In the reel stop process, the stop operation instruction signals 113a to 113c are detected, and when the stop button is operated, on the reel obtained at the stop button operation timing based on the stop link table corresponding to the winning prize. The symbol to be stopped is determined with reference to the stop table from the symbol position (symbol number PN). After that, the reel stop process is applied to each reel by applying a braking force by all-phase excitation that exemplifies all winding phases at the same time, and rotating and stopping by inertia corresponding to 15 steps after starting all-phase excitation. Do it.

  For example, if the result of the internal lottery is lost, the reel stop process delays the reel stop timing even if the player performs a stop operation at the timing when the symbol that constitutes the winning combination has reached the valid winning line. Thus, the symbols that make up the winning combination should not stop on a valid winning line. The same applies to a role corresponding to a prize that was not won in the internal lottery. On the other hand, when a prize that is an internal lottery is won, the player performs a stop operation not only at the timing when the symbols that make up the winning prize are on the valid winning line, but at a slightly earlier timing. However, the pull-in control is performed so that the symbols constituting the winning combination stop on the winning line. In the present embodiment, the maximum number of frames that can be drawn by this pulling control is set to four frames.

  Next, when all reels are stopped, the CPU 101 determines whether or not a winning combination is established on a valid winning line (S110), and if winning, a game value set for each winning combination is given. To do. Next, the CPU 101 performs notification processing (S111). As will be described in detail later, in the notification process, when the SB prize (SB1 prize, SB2 prize, SB3 prize) is won in the game and the expression of the SB game (SB1 game to SB3 game) is confirmed, the CPU 101 stores in the ROM 104. An image for notifying a specific winning line group from among the plurality of types of winning line groups displayed is displayed on the liquid crystal display 30. The specific winning line group is a winning line group that is advantageous to the player in the game of the SB game starting from the next game. Next, the CPU 101 performs a game end determination process (S112), and subsequently performs a lottery information clear process (S113). Here, if the winning prize in the game is a start prize (for example, RB prize) that can be carried over after the next game, the lottery information is cleared only when the prize is won, and it is dropped without winning. In this case, the lottery information is not cleared and is left as it is. On the other hand, if the prize won in the game is a start prize or small part prize that cannot be carried over, the lottery information is cleared regardless of winning or missing.

  Next, the CPU 101 determines whether or not a replay prize has been won (S114). If it is determined that a replay prize has been won, an automatic bet process is performed (S100a), and the process returns to step S101. On the other hand, when it is determined that the replay prize has not been won, the prohibition of the betting operation performed in step S102 is canceled (S115), and the insertion of the game medal or the input of the bet button 11 can be accepted. Subsequently, in order to prepare for the start of the next game, the process returns to step S100.

<A-4-2: Prize lottery table selection process>
FIG. 10 shows the prize lottery table selected in the prize lottery table determination process in step S106. In executing the internal lottery, the CPU 101 selects the prize lottery table TBL11 in the normal game, selects the prize lottery table TBL12 in the SB1 game, selects the prize lottery table TBL13 in the SB2 game, and selects the prize lottery table TBL14 in the SB3 game. In the RB inside game, the prize lottery table TBL15 is selected, and in the RB game, the prize lottery table TBL16 is selected. Then, the CPU 101 executes a lottery based on the selected prize lottery table. Each prize lottery table TBL11 to TBL16 includes a plurality of lottery sections, and each of the plurality of lottery sections stores a numerical value corresponding to the selection probability selected in the lottery. In the slot machine 1, since a pseudo random number is generated using a counter circuit that sequentially increments in the range from 0000H to FFFFH, the denominator of the fraction indicating the selection probability is “65536”, and each lottery section Stores a numerical value corresponding to the numerator of the selection probability. For example, the lottery category 1 is a lottery category corresponding to the RB prize. “436” is stored in the lottery section 1 corresponding to the prize lottery tables TBL11, TBL12, TBL13, and TBL14 selected in the base game, the SB1 game, the SB2 game, and the SB3 game, and the lottery section 1 is “436/65536”. A lottery will be drawn with the selection probability. In addition, “0” is stored in the lottery category 1 corresponding to the prize lottery tables TBL15 and TBL16 selected in the RB inside game and the RB game, and it is excluded from the lottery object. If lottery category 1 is selected as a result of internal lottery in the base game, SB1 game, SB2 game, and SB3 game, an RB prize is won, and the CPU 101 sets lottery information corresponding to the RB prize. Further, in the RB game and the RB internal game, the CPU 101 executes the lottery by excluding the RB prize from the lottery target.

  The lottery sections 2 to 4 are lottery sections corresponding to the SB1 prize, the SB2 prize, and the SB3 prize, respectively. “1456” is stored in the lottery sections 2 to 4 corresponding to the prize lottery tables TBL11 to TBL14, and the lottery sections 2 to 4 are lottery with a selection probability of “1456/65536”. When these lottery sections are selected as a result of the internal lottery in the base game, the SB1 game, the SB2 game, and the SB3 game, the CPU 101 sets the prize lottery information corresponding to the lottery section. Further, “0” is stored in the lottery sections 2 to 4 corresponding to the prize lottery tables TBL15 and TBL16. That is, in the RB game and the RB internal game, the CPU 101 executes the lottery by excluding the SB1 prize, the SB2 prize, and the SB3 prize from the lottery targets.

  The lottery category 5 is a lottery category corresponding to the replay prize. “8978” is stored in the lottery section 5 corresponding to the prize lottery tables TBL11 to TBL14, and the lottery section 5 is drawn with a selection probability of “8978/65536”. When the lottery category 5 is selected as a result of the internal lottery in the normal game, the SB1 game, the SB2 game, and the SB3 game, the CPU 101 sets lottery information corresponding to the replay prize. “32768” is stored in the lottery section corresponding to the prize lottery table TBL15 selected in the RB inside game, and the lottery section 5 is lottery with a selection probability of “32768/65536”. Therefore, in the RB inside game, the replay prize winning probability is higher than in the normal game and the SB game. When the lottery category 5 is selected as a result of the internal lottery in the RB inside game, the CPU 101 sets lottery information corresponding to two awards, the replay award and the RB award carried over. Further, “0” is stored in the lottery section 5 corresponding to the prize lottery table TBL16 selected in the RB game. That is, in the RB game, the replay prize is excluded from the lottery targets and the lottery is executed.

  The lottery section 6 is a lottery section corresponding to the bell prize. “65536” is stored in the lottery section 6 corresponding to the prize lottery table TBL16 selected in the RB game, and the lottery section 6 is drawn with a selection probability of “65536/65536”. That is, in the RB game, 100% of the bell prize is won. If the lottery category 6 is selected as a result of the internal lottery in the RB game, the CPU 101 sets lottery information corresponding to the bell prize. Further, “5188” is stored in the lottery section 6 corresponding to the prize lottery tables TBL11 to TBL15, and the lottery section 6 is lottery with a selection probability of “5188/65536”. When the lottery category 6 is selected as a result of the internal lottery in the base game, the SB1 game, the SB2 game, the SB3 game, and the RB internal middle game, the CPU 101 sets lottery information corresponding to the bell prize. When the lottery category 6 is selected as a result of the internal lottery in the RB inside game, the CPU 101 sets lottery information corresponding to the two awards, the bell award and the RB award carried over.

  The lottery section 7 is a lottery section corresponding to the Cherry 1 prize. In the present embodiment, the Cherry 1 Award is associated with the SB 1 Award, and the SB 1 Game is set such that the probability of winning the Cherry 1 Award is higher than other games (that is, the SB 1 Game There is a higher possibility of winning the Cherry 1 Award than in the game. Hereinafter, specific contents will be described. “46566” is stored in the lottery section 7 corresponding to the prize lottery table TBL12 selected in the SB1 game, and the lottery section 7 is lottery with a selection probability of “46566/65536”. Therefore, in the SB1 game, the probability of winning the Cherry 1 prize is high. When the lottery category 7 is selected as a result of the internal lottery in the SB1 game, the CPU 101 sets lottery information corresponding to the Cherry 1 prize. Further, “0” is stored in the lottery section 7 corresponding to the prize lottery tables TBL11 and TBL13 to TBL16. Therefore, in games other than the SB1 game, the lottery is executed by excluding the Cherry 1 prize from the lottery targets.

  The lottery section 8 is a lottery section corresponding to the Cherry 2 award. In the present embodiment, the Cherry 2 award is associated with the SB 2 award, and the SB 2 game is set such that the probability of winning the Cherry 2 award is higher than other games (that is, the SB 2 game There is a higher possibility of winning the Cherry 2 Award than in the game. Hereinafter, specific contents will be described. “46566” is stored in the lottery section 8 corresponding to the prize lottery table TBL13 selected in the SB2 game, and the lottery section 8 is lottery with a selection probability of “46566/65536”. Therefore, in the SB2 game, the winning probability of the Cherry 2 prize is high. When the lottery section 8 is selected as a result of the internal lottery in the SB2 game, the CPU 101 sets lottery information corresponding to the Cherry 2 prize. Further, “0” is stored in the lottery section 8 corresponding to the prize lottery tables TBL11 and TBL12 and TBL14 to TBL16. Therefore, in games other than the SB2 game, the lottery is executed by excluding the Cherry 2 award from the lottery targets.

  The lottery section 9 is a lottery section corresponding to the Cherry 3 award. In this embodiment, the Cherry 3 Award is associated with the SB 3 Award, and in the SB 3 Game, the probability of winning the Cherry 3 Award is set higher than other games (that is, the SB 3 Game There is a higher possibility of winning the Cherry 3 Award than in the game. Hereinafter, specific contents will be described. “46566” is stored in the lottery section 9 corresponding to the prize lottery table TBL14 selected in the SB3 game, and the lottery section 9 is lottery with a selection probability of “46566/65536”. Therefore, in the SB3 game, the winning probability of the cherry 3 prize is high. As a result of the internal lottery in the SB3 game, when the lottery category 9 is selected, the CPU 101 sets lottery information corresponding to the cherry 3 prize. Further, “0” is stored in the lottery section 9 corresponding to the prize lottery tables TBL11 to TBL13, TBL15, and TBL16. That is, in games other than the SB3 game, the cherry 3 prize is excluded from the lottery targets and the lottery is executed.

  The lottery section 10 is a lottery section corresponding to a loss. “46566” is stored in the lottery section 10 corresponding to the prize lottery table TBL11 selected in the base game, and the lottery section 10 is lottery with a selection probability of “46566/65536”. Further, “27580” is stored in the lottery section 10 corresponding to the prize lottery table TBL15 selected in the RB inside game, and the lottery section 10 is lottery with a selection probability of “27580/65536”. Further, “0” is stored in the lottery section 10 corresponding to the prize lottery tables TBL12, TBL13, TBL14, and TBL16 selected in the SB1 game, the SB2 game, the SB3 game, and the RB game. That is, in these games, the lottery is executed by excluding the lose from the lottery target.

<A-4-3: Notification process>
FIG. 11 is a flowchart showing the content of the notification process in step S111. First, the CPU 101 determines whether or not the SB1 award has been won as a result of the winning determination process in step S110 (S111a). If the CPU 101 determines that the SB1 award has been won, the “Cherry-ANY” related to winning the Cherry 1 award is a game of the SB1 game (a game that increases the winning probability of the Cherry 1 award) starting from the next game. -ANY "when the line of symbols is stopped on an activated pay line, a winning line group that allows multiple winnings (that is, the player has an advantage over selecting another winning line group) The winning line group) is notified. More specifically, when the CPU 101 determines that the SB1 prize has been won, as shown in FIG. 12, a winning line group that is recommended to be selected in the next game (hereinafter referred to as “recommended line group”). As an example, an image for informing a winning line set including the first winning line L1, the second winning line L2, and the third winning line L3 is displayed on the liquid crystal display 30 (S111b).

  It is assumed that the Cherry 1 prize is won by an internal lottery in the game of the SB1 game, and the “Cherry” symbol stops at the middle display position (M1) of the left reel R1 in the winning game. At this time, as shown in FIG. 5A, if a winning line group consisting of the first winning line L1, the second winning line L2, and the third winning line L3 is selected, the three winning lines are displayed on the three winning lines. Overlap wins and 15 medals can be obtained as dividends. On the other hand, there are a winning line set consisting of the first winning line L1, the fourth winning line L4 and the fifth winning line L5, and a winning line set consisting of the first winning line, the sixth winning line and the seventh winning line. If it is selected, only the Cherry 1 prize is won on the first winning line L1, the fourth winning line L4, or the fifth winning line L5 (FIG. 5 (b) and ( c)), and only 5 medals are obtained as a payout. As described above, when a player wins the SB1 prize in a certain game, the winning line including the first winning line L1, the second winning line L2, and the third winning line L3 is performed in the next game in accordance with the above notification. If a group is selected, it is possible to enjoy the benefit of having a double prize when winning the Cherry 1 prize in the next game. As described above, since the winning line group including the first winning line L1, the second winning line L2, and the third winning line L3 is associated with the BET number “1”, the player sets the BET number. By selecting “one”, a winning line set including the first winning line L1, the second winning line L2, and the third winning line L3 can be selected.

  In the present embodiment, among the “Red 7-R-R” symbols that are the winning symbols of the SB1 award, the “R” symbol is a symbol that can be drawn 100%. If the “Red 7” symbol stops above, the winning of the SB1 prize is confirmed at that time. The CPU 101 can perform the above notification at the time.

  If it is determined in step S111a that the SB1 award has not been won, the CPU 101 determines whether or not the SB2 award has been won (S111c). If the CPU 101 determines that the SB2 award has been won, the “ANY-Cherry” related to winning the Cherry 2 award is a game of the SB2 game (a game that increases the winning probability of the Cherry 2 award) starting from the next game. When the arrangement of symbols “-ANY” is stopped on the activated pay line, a pay line group that allows double winning is notified. More specifically, when it is determined that the CPU 101 has won the SB2 prize, as shown in FIG. 13, the first winning line L1, the fourth winning line L4, and the fifth winning line group are set as recommended line groups in the next game. An image for informing a winning line set including the winning line L5 is displayed on the liquid crystal display 30 (S111d).

  Assume that a cherry 2 prize is won by an internal lottery in the game of the SB2 game, and the “cherry” symbol stops at the middle display position (M2) of the middle reel R2 in the winning game. At this time, as shown in FIG. 5B, if a winning line group consisting of the first winning line L1, the fourth winning line L4, and the fifth winning line L5 is selected, the three winning lines are displayed on the three winning lines. Overlap wins and 15 medals can be obtained as dividends. On the other hand, there are a winning line set consisting of a first winning line L1, a second winning line L2 and a third winning line L3, and a winning line set consisting of a first winning line, a sixth winning line and a seventh winning line. If it is selected, only the Cherry 2 award is won on the first winning line L1, the fourth winning line L4, or the fifth winning line L5 (see FIG. 5 (a) and ( c)), and only 5 medals are obtained as a payout. As described above, when a player wins the SB2 prize in a certain game, the winning line including the first winning line L1, the fourth winning line L4, and the fifth winning line L5 is performed in the next game according to the above notification. If a group is selected (that is, if the number of BETs in the next game is set to “2”), it is possible to enjoy the benefit of having a double prize when winning the Cherry 2 prize in the next game.

  In the present embodiment, if the “red 7” symbol stops on the activated pay line in the middle reel R2, the winning of the SB2 award is confirmed at that time, so the CPU 101 determines that the above mentioned Notification can be performed.

  If it is determined in step S111c that the SB2 award has not been won, the CPU 101 determines whether or not the SB3 award has been won (S111e). If the CPU 101 determines that the SB3 award has been won, the “ANY-ANY” related to winning the Cherry 3 award is a game of the SB3 game (a game that increases the winning probability of the Cherry 3 award) starting from the next game. -When the arrangement of symbols of "cherry" is stopped on the activated pay line, a winning line group that allows double winning is notified. More specifically, when the CPU 101 determines that the SB3 prize has been won, as shown in FIG. 15, the first winning line L1, the sixth winning line L6, and the seventh winning line group as the recommended line group in the next game are shown. An image for notifying the winning line set including the winning line L7 is displayed on the liquid crystal display 30 (S117f).

  It is assumed that the cherry 3 prize is won by the internal lottery in the SB3 game, and the “cherry” symbol stops at the middle display position (M3) of the right reel R3 in the winning game. At this time, as shown in FIG. 5C, if a winning line group consisting of the first winning line L1, the sixth winning line L6, and the seventh winning line L7 is selected, on these three winning lines. Overlap wins and 15 medals can be obtained as dividends. On the other hand, a winning line group consisting of the first winning line L1, the second winning line L2, and the third winning line L3, or a winning line consisting of the first winning line L1, the fourth winning line L4, and the fifth winning line L5. When the line group is selected, only the Cherry 3 prize is won on the first prize line L1, the fourth prize line L4, or the fifth prize line L5 (see FIG. 5A). ) And (c)), and only 5 medals are obtained as a payout. As described above, when a player wins the SB3 prize in a certain game, according to the above notification, the player selects a winning line group consisting of the first winning line, the sixth winning line, and the seventh winning line in the next game. If this is done (that is, if the number of BETs in the next game is set to “3”), then it is possible to enjoy the benefit that if the third game is won in the next game, double winnings are achieved.

  In the present embodiment, when the “red 7” symbol stops on the activated pay line in the right reel R3, the winning of the SB3 award is confirmed at that time, so that the CPU 101 determines that the above-mentioned award Notification can be performed.

  On the other hand, if it is determined in step S111e that the SB3 award has not been won, the process is terminated without notification (S111g).

<A-5: Action and effect>
As described above, the CPU 101 increases the probability of winning the Cherry Award (Cherry 1 Award to Cherry 3 Award) by winning the SB Award (SB1 Award to SB3 Award) (SB1 Game to SB3 Game). If the expression is confirmed, the player is notified of a specific winning line set that allows a double winning when the Cherry Prize is won in the game of the SB game. Then, the player can enjoy the benefit that when the SB game is selected, the specific winning line group is selected, so that when the player wins the cherry prize in the game, the prize is duplicated.

<B: Second Embodiment>
In the first embodiment described above, when the expression of an SB game (a game with a higher probability of winning the Cherry Prize) is confirmed by satisfying a predetermined condition, a duplicate prize is awarded when the Cherry Prize is won in the game of the SB game. The player was notified of possible winning line groups. On the other hand, in the second embodiment, when the expression of the RB internal game (the game in which the winning of the RB prize is permitted) is confirmed by satisfying a predetermined condition, the player can play the game of the RB internal game. A winning line set that can be awarded 100% to the RB award regardless of the timing of pressing the stop button (13a, 13b, 13c) is notified. Hereinafter, the description will focus on the parts that are different from the first embodiment, and the description of the overlapping parts will be omitted as appropriate.

  The external configuration of the slot machine according to the second embodiment is the same as that of the slot machine 1 according to the first embodiment except for the arrangement of symbols printed on the reel bands corresponding to the reels R1 to R3 (FIG. 1). . FIG. 15 is a diagram showing the arrangement of symbols printed on the reel bands corresponding to the reels R1 to R3.

  In the second embodiment, the winning line set corresponding to the BET number “1” and the winning line set corresponding to the BET number “3” are different from those in the first embodiment. As shown in FIG. 16A, the winning line group corresponding to the BET number “1” is the eighth winning line L8, the ninth winning line L9, the tenth winning line L10, the eleventh winning line L11, and the twelfth. It consists of a winning line L12, a thirteenth winning line L13, a fourteenth winning line L14, and a fifteenth winning line L15. The eighth pay line L8 is a V-shaped line connecting the upper display position (U1) of the left reel R1, the lower display position (D2) of the middle reel R2, and the upper display position (U3) of the right reel R3. The ninth line L9 is an inverted V-shaped line connecting the lower display position (D1) of the left reel R1, the upper display position (U2) of the middle reel R2, and the lower display position (D3) of the right reel R3. The tenth winning line L10 is a line connecting the upper display position (U1) of the left reel R1, the upper display position (U2) of the middle reel R2, and the upper display position (U3) of the right reel R3. The eleventh winning line L11 is a line connecting the lower display position (D1) of the left reel R1, the lower display position (D2) of the middle reel R2, and the lower display position (D3) of the right reel R3. The twelfth winning line L12 is a line connecting the upper display position (U1) of the left reel R1, the upper display position (U2) of the middle reel R2, and the lower display position (D3) of the right reel R3. The thirteenth winning line L13 is a line connecting the upper display position (U1) of the left reel R1, the lower display position (D2) of the middle reel R2, and the lower display position (D3) of the right reel R3. The fourteenth pay line L14 is a line connecting the lower display position (D1) of the left reel R1, the upper display position (U2) of the middle reel R2, and the upper display position (U3) of the right reel R3. The fifteenth pay line L15 is a line connecting the lower display position (D1) of the left reel R1, the lower display position (D2) of the middle reel R2, and the upper display position (U3) of the right reel R3. Also, as shown in FIG. 16 (b), the winning line group corresponding to the BET number “3” is the first winning line L1, the fourth winning line L4, the fifth winning line L5, and the tenth winning line L10. It consists of an eleventh winning line L11.

  FIG. 17 is an explanatory diagram for explaining the prizes and combinations in the slot machine according to the second embodiment, and shows the configuration of the types of prizes and their combinations (combination of symbols). In the second embodiment, as the start prize, there is an RB prize composed of a combination of symbols “BAR-BAR-BAR” (also referred to as “BAR combination”) for starting the RB game. For the small role award, the “Belle-Bell-Bell” symbol combination (also referred to as “Bell role”) with 9 medals as dividends, and the “Cherry-ANY” with 3 medals as dividends. There is a cherry award consisting of a combination of symbols “ANY” (also called “cherry”). In addition, there is a re-game prize consisting of a combination of symbols of “R-R-R” (also referred to as “replay role”) in which the next game is played without a betting operation. In the second embodiment, the “R” symbol and the “bell” symbol are 100% retractable symbols.

FIG. 18 is an explanatory diagram showing the types of games played in the slot machine according to the second embodiment. FIG. 18A shows transitions between a plurality of games performed in the slot machine according to the second embodiment.
(1) Start and end of RB game When an RB prize is won by an internal lottery while a normal game is being executed, and the "BAR role" for winning the RB prize is established on the winning line, the RB game is played from the next game. Start. The RB game is played a maximum of 12 times, and when the RB game is won eight times during the execution of the RB game, the RB game is terminated.
(2) RB inside game Even if the RB prize is won on the winning line even if the RB prize is won by the internal lottery during the normal game, if the “BAR role” to win the RB prize is not established on the winning line, the RB prize will be won after the next game. This is an RB inside game in which the winning flag of the RB prize is carried over until the “BAR combination” is established and won. When the “BAR combination” is established in the RB inside game and the prize is won, the RB game starts from the next game.
Here, in the RB inside game, the RB prize is always won internally, and the winning probability for the RB prize is 100%. The possibility of winning the RB award can be expressed by the probability of winning the RB award x the probability that the symbols that make up the RB role on the active line will stop. It can be said that the possibility of winning the RB prize is higher than that of this type of game (for example, a normal game).

  In the slot machine according to the second embodiment, the game type is managed by the game type flag shown in FIG. When bit 1 of the game type flag is set to “1” as the RB game in-progress flag, it indicates that the RB game is in progress, and when bit 1 is set to “1” as the RB internal in-game flag, it is inside the RB Indicates the middle game. If any bit indicates “0” without being set, it indicates that a normal game is being played.

Although the flow of one game in the second embodiment is the same as that in the first embodiment (see FIG. 9), the contents of the prize lottery table determination process in step S106 and the contents of the notification process in step S111 are the first embodiment. And different. Hereinafter, each content is demonstrated.
FIG. 19 is a diagram showing a prize lottery table selected in the prize lottery table determination process in step S106. In executing the internal lottery, the CPU 101 selects the prize lottery table TBL21 in the normal game, selects the prize lottery table TBL22 in the RB game, and selects TBL23 in the RB internal game. Then, the CPU 101 executes a lottery based on the selected prize lottery table. Each of the prize lottery tables TBL21 to TBL23 includes a plurality of lottery sections, and each of the plurality of lottery sections stores a numerical value corresponding to the selection probability selected in the lottery. In the slot machine 1, since a pseudo random number is generated using a counter circuit that sequentially increments in the range from 0000H to FFFFH, the denominator of the fraction indicating the selection probability is “65536”, and each lottery section Stores a numerical value corresponding to the numerator of the selection probability. For example, the lottery category 1 is a lottery category corresponding to the RB prize. “436” is stored in the lottery category 1 corresponding to the prize lottery table TBL21 selected in the base game, and the lottery category 1 is drawn with a selection probability of “436/65536”. If the lottery category 1 is selected as a result of the internal lottery in the normal game, the RB prize is won, and the CPU 101 sets the lottery information corresponding to the RB prize. Further, “0” is stored in the lottery section 1 corresponding to the prize lottery tables TBL22 and TBL23 selected in the RB inside game and the RB game. That is, in the RB game and the RB inside game, the CPU 101 executes the lottery by excluding the RB prize from the lottery target.

  The lottery category 2 is a lottery category corresponding to the replay prize. “8978” is stored in the lottery category 2 corresponding to the prize lottery table TBL21 selected in the base game, and the lottery category 2 is drawn with a selection probability of “8978/65536”. When the lottery category 2 is selected as a result of the internal lottery in the normal game, the CPU 101 sets lottery information corresponding to the replay prize. Further, “0” is stored in the lottery section 2 corresponding to the prize lottery table TBL22 selected in the RB game. That is, in the RB game, the CPU 101 executes the lottery by excluding the replay prize from the lottery target. Furthermore, “32768” is stored in the lottery section 2 corresponding to the prize lottery table TBL23 selected in the RB inside game, and the lottery section 2 is drawn with a selection probability of “32768/65536”. When the lottery category 2 is selected as a result of the internal lottery in the RB inside game, the CPU 101 sets lottery information corresponding to the two awards of the replay award and the RB award carried over.

  The lottery category 3 is a lottery category corresponding to the Bell Prize. “5188” is stored in the lottery section 3 corresponding to the prize lottery tables TBL21 and TBL23 selected in the base game and the RB inside game, and the lottery section 3 is lottery with a selection probability of “5188/65536”. When the lottery category 3 is selected as a result of the internal lottery in the normal game or the RB inside game, the CPU 101 sets lottery information corresponding to the bell prize. When the lottery category 3 is selected as a result of the internal lottery in the RB inside game, the CPU 101 sets lottery information corresponding to the two awards, the bell award and the RB award carried over. Further, “64512” is stored in the lottery category 3 corresponding to the prize lottery table TBL22 selected in the RB game, and the lottery category 3 is drawn with a selection probability of “64512/65536”. When the lottery category 3 is selected as a result of the internal lottery in the RB game, the CPU 101 sets lottery information corresponding to the bell prize.

  The lottery category 4 is a lottery category corresponding to the Cherry Prize. “1024” is stored in the lottery section 4 corresponding to the prize lottery tables TBL21, TBL22, and TBL23 selected in the base game, the RB game, and the RB inside game, and the lottery section 4 has a selection probability of “1024/65536”. A lottery will be held.

  The lottery section 5 is a lottery section corresponding to a loss. “49910” is stored in the lottery section 5 corresponding to the prize lottery table TBL21 selected in the base game, and the lottery section 5 is drawn with a selection probability of “49910/65536”. Further, “0” is stored in the lottery section 5 corresponding to the prize lottery table TBL22 selected in the RB game. That is, in the RB game, the lottery is executed by excluding the lose from the lottery object. Furthermore, “26556” is stored in the lottery section 5 corresponding to the prize lottery table TBL23 selected in the RB inside game, and the lottery section 5 is lottery with a selection probability of “26556/65536”.

  FIG. 20 is a flowchart showing the content of the notification process in step S111. First, the CPU 101 determines whether or not the RB prize is won in the internal lottery of the game (S111h). If it is determined that the RB prize is won, the CPU 101 determines whether or not the RB prize is won in the game (S111i). When it is determined that the RB award has not been won, that is, when it is determined that the RB internal game is started from the next game (expression of the RB internal game is determined), the game of the RB internal game When the player tries to stop the arrangement of symbols “BAR-BAR-BAR” related to winning the RB prize on the activated winning line, the player can use the stop button (13a, 13b) at any timing. , 13c), a winning line set that allows 100% winning in the RB award is notified. More specifically, when the CPU 101 determines that the RB prize is won in the internal lottery in the game but the RB prize is not won in the game, the recommended line in the next game is shown in FIG. As a set, an image for informing a winning line set including the winning lines L8 to L15 is displayed on the liquid crystal display 30 (S111j). If it is determined in step S111h that the RB award has not been won, and if it is determined in step S111i that the RB award has been won, the CPU 101 ends the processing without performing notification (S111k).

  Assume that an RB prize is won by an internal lottery in a game and no RB prize is won in the game. As described above, even if the RB prize is won in the internal lottery, if the “BAR role” for winning the RB prize is not established on the winning line, the “BAR role” for winning the RB prize after the next game is established. It becomes an RB inside game that carries the winning flag of the RB prize until it wins. In the present embodiment, in the game of the RB internal game, as shown in FIG. 16A, if the pay lines L8 to L15 are activated, the player can use the stop button (13a, Even if 13b, 13c) is pressed, 100% of the RB prize can be won. The reason will be described below.

  As described above, the slot machine according to the present embodiment can draw and stop a maximum of four symbols constituting a prize. When the lower display position of each reel R1 to R3 is the first symbol (frame), the symbol “BAR” is located at the position from the first frame up to the seventh symbol The symbol “BAR” can be stopped at the upper display positions (U1 to U3) or the lower display positions (D1 to D3) of the reels R1 to R3 by the reel stop control. In this embodiment, as shown in FIG. 15, the symbol “BAR” has an interval of 6 symbols (6 frames) on the same reel from one “BAR” symbol to the next “BAR” symbol. ) Is placed within. Therefore, since the seven symbols arranged continuously on each of the reels R1 to R3 always include the symbol “BAR”, the player can use the stop button (13a, 13b, 13c) at any timing. Even when is pressed, the symbol “BAR” can be stopped at the upper display positions (U1 to U3) or the lower display positions (D1 to D3) of the reels R1 to R3.

  Here, as the lines connecting the upper display positions (U1 to U3) or the lower display positions (D1 to D3) of the reels R1 to R3, the above-described eighth pay line L8, ninth pay line L9, and tenth pay line are described. There are eight modes, L10, eleventh winning line L11, twelfth winning line L12, thirteenth winning line L13, fourteenth winning line L14 and fifteenth winning line L15. Therefore, in the RB inside game, if all the above eight pay lines are activated, the eighth pay line L8 to L8 no matter what timing the player presses the stop button (13a, 13b, 13c). The “BAR combination” is established on any of the 15 winning lines L15. In other words, if all of the eighth pay line L8 to the fifteenth pay line L15 are not activated, the player cannot win the RB prize unless the player presses the stop button at an appropriate timing. As described above, if the player selects a winning line set including the eighth winning line L8 to the fifteenth winning line L15 according to the above notification, the player can press the stop button (13a, 13b, 13c) at any timing. Can also benefit from being able to win 100% of the RB award. As described above, in the present embodiment, the winning line group including the eighth winning line L8 to the fifteenth winning line L15 is associated with the BET number “1”, so the player sets the BET number to “1”. By selecting “sheet”, the winning line group can be selected.

  As described above, when the occurrence of the RB internal game is confirmed by satisfying a predetermined condition, the CPU 101 determines at what timing the player presses the stop button (13a, 13b, 13c) in the game of the RB internal game. ), A specific winning line set that can be 100% won in the RB prize is notified. Then, the player can enjoy the benefit of being able to win 100% of the RB award by selecting the specific winning line group in the game of the RB inside game.

<C: Modification>
Various modifications are added to the above embodiments. Specific modifications are exemplified below. Two or more aspects arbitrarily selected from the following examples may be merged.

(1) Modification 1
In the notification process in each of the above-described embodiments, the CPU 101 is a game (for example, an SB1 game to an SB3 game, which is highly likely to win a specific prize (for example, Cherry 1 Award to Cherry 3 Award, RB Award) by satisfying a predetermined condition. When the expression of the (RB inside game) is confirmed, when the arrangement of symbols in a predetermined mode related to winning a specific prize in the game of the game is stopped on the activated pay line or when it is to be stopped In this case, the CPU 101 reports a specific winning line group that is advantageous to the player as compared with the case where another winning line group is selected. For example, the CPU 101 notifies a specific BET number instead of notifying the specific winning line group. It can also be controlled to notify.

  For example, in the notification process (see FIG. 11) of the first embodiment described above, when the CPU 101 determines that the SB1 prize is won, as shown in FIG. 22, a game in the SB1 game started from the next game is performed. It is also possible to perform control for displaying on the liquid crystal display 30 an image in which “1” is recommended as the BET number. As described above, in the first embodiment, the winning line set corresponding to the BET number “1” is composed of the first winning line L1, the second winning line L2, and the third winning line L3. Reporting the BET number “1” is nothing other than reporting the winning line group including the first winning line L1, the second winning line L2, and the third winning line L3 (that is, the contents of FIG. 11). The same).

  If the CPU 101 determines that the SB2 prize has been won, as shown in FIG. 23, the liquid crystal display displays an image recommending “2” as the BET number of games in the SB2 game starting from the next game. It is also possible to perform control to display on 30. In the first embodiment, the winning line group corresponding to the BET number “2” is composed of the first winning line L1, the fourth winning line L4, and the fifth winning line L5. Is a notification of a winning line group including the first winning line L1, the fourth winning line L4, and the fifth winning line L5 (that is, the same as the contents of FIG. 11). Further, if the CPU 101 determines that the SB3 prize has been won, as shown in FIG. 24, the liquid crystal display displays an image recommending “3” as the BET number of games in the SB3 game starting from the next game. It is also possible to perform control to display on 30. In the first embodiment, the winning line group corresponding to the BET number “3” is composed of the first winning line L1, the sixth winning line L6, and the seventh winning line L7. Is a notification of a winning line group including the first winning line L1, the sixth winning line L6, and the seventh winning line L7 (that is, the same as the contents of FIG. 11).

(2) Modification 2
In the notification process in each of the above-described embodiments, the CPU 101 performs a control to display an image for notifying a specific winning line group on the liquid crystal display 30 that is advantageous to the player as compared to the case where another winning line group is selected. However, the present invention is not limited to this, and the manner of notification is arbitrary. For example, a specific winning line set can be notified by voice. In addition, a specific winning line set can be notified by both sound and image.

(3) Modification 3
In the above-described embodiment, each of a plurality of types of winning line sets is associated with the number of BETs, and the winning line group that is selected (validated) for each game is determined according to the number of BETs in the game. However, the present invention is not limited to this, and a mode in which the winning line group and the BET number are not associated with each other can also be adopted. In this aspect, operation means is provided for the player to designate each of the plurality of winning line sets, and when the CPU 101 detects that the operation means has been operated by the player, the operation means is designated by the operation. For example, one winning line group is selected and one or more types of winning lines constituting the selected winning line group are activated. In this aspect, the number of BETs in each game can always be defined as the same number (for example, 3).

(4) Modification 4
In each of the above-described embodiments, each of the plurality of types of winning line sets includes a plurality of types of winning lines. However, the present invention is not limited to this, and the number (type) of winning lines constituting one winning line set is as follows. For example, the winning line group may be configured by one winning line. Further, the number of winning lines constituting the winning line group may be different for each winning line group. In short, each of the plurality of types of winning line sets may be an aspect constituted by one or a plurality of types of winning lines.

(5) Modification 5
In each of the above-described embodiments, the combination of the BET number and the winning line group corresponding to the BET number is arbitrary. For example, in the first embodiment, the winning line set corresponding to the BET number “1” may be configured by the first winning line L1, the fourth winning line L4, and the fifth winning line L5, A winning line L1, a sixth winning line L6, and a seventh winning line L7 can also be configured. The same applies to the BET numbers “2” and “3”.
