Description

  The present invention relates to a slot machine.

The slot machine is equipped with multiple reels with multiple symbols, the game starts when the player's medal is inserted, the multiple reels rotate all at once by operating the start lever, and the player's reel stop button is operated. The reels stop sequentially based on the above. Then, after all the reels are stopped, when a combination of symbols for winning is arranged on the winning line, the winning is made, and a game for giving a player a game value corresponding to the prize is executed. In the slot machine, a plurality of prizes are set, and a combination of symbols corresponding to each prize and a game value to be given by winning are determined. A plurality of prizes include a small prize that can earn a predetermined number of medals as a game value given when winning, a start prize that can start a bonus game as a game value given when winning, etc. is there. In the bonus game that is started by winning the start prize, a large number of medals can be obtained in a short time.
In the slot machine, an internal lottery is executed for a plurality of prizes or loses at the start lever operation timing, and winning information indicating the lottery result is generated. When the timing of the player's operation of the reel stop button is appropriate, the winning information is controlled so that combinations of symbols corresponding to a prize indicating winning are aligned on the winning line. Regardless of the timing of the player's operation of the reel stop button, control is performed so that combinations of symbols corresponding to a prize that does not indicate winning in the winning information are not aligned on the winning line. For the reel stop control, a stop table associated with each of a plurality of prizes is generally used. In the stop table, the symbol number assigned to each symbol of the reel and the stop position of the reel are stored in association with each other. In the stop control, the symbol number at the timing of the operation of the reel stop button is acquired, and the reel is stopped at the stop position corresponding to the acquired symbol number.

  If the winning information indicates winning of any award, the winning combination will be awarded when the symbol combination corresponding to the winning prize is aligned on the winning line according to the timing of the player's reel stop button operation or the pressing order. If no symbol combination is available, no prize will be awarded. The fact that the symbol combinations corresponding to the winning prizes are not complete and cannot be won is called “missing”. Regardless of whether or not the winning information indicates the winning of any prize, the combination of symbols that will win on the winning line after all reels were stopped was not aligned on any winning line. Is called "Non-winning".

In the conventional slot machine, when the reel stop button to be operated first among the three reel stop buttons is predetermined in relation to the pressing order, at what timing the three reels While it is possible to win even if the stop button is operated, when it is not predetermined, stop control is known in which a winning / non-winning is determined according to the operation timing of the three reel stop buttons (patent) Reference 1).
There is also known a slot machine in which a normal replay award and a special replay award are simultaneously elected, and one of the normal replay and the special replay is always awarded by distribution of 6 selections (see Patent Document 2).

However, in the slot machine described in Patent Document 1, there is a problem in that the second stop operation is no longer an object of interest for the player because even if the first stop operation is correct, a winning is always made. .
Further, in the slot machine described in Patent Document 2, since one of the prizes won at the same time is always won, there is no case where no winning is made when the pressing order is wrong.
It is an object of the present invention to provide a slot machine that may become non-winning if the push order of the second stop operation is wrong even if the push order of the first stop operation is correct. To do.

In order to solve the above-described problem, the slot machine according to the present invention has a plurality of display rows (R1) that can be variably displayed in a predetermined number of symbols when a game is started once the game medium is consumed. , R2, R3), when all the variable displays are stopped, a winning combination is obtained when a combination of a predetermined set of symbols is arranged on the winning line, and a game value corresponding to the type of winning combination is given once. In the slot machine where the game ends, a pre-determining means (101) for predetermining the types of winning combinations and a plurality of display rows (R1, R2, R3) are provided corresponding to each of the players. When a plurality of stop operation means (13a, 13b, 13c) for inputting a variable display stop operation and a plurality of stop operation means (13a, 13b, 13c) are received, the stop operation is performed. Stop control means (101) for controlling the variable display of the display column corresponding to the digit stop operation means to stop by moving the symbol within the drawing range which is the maximum number of moving frames, The winning combination includes the correct combination, the first selection combination, and the second selection combination, and in the display row, the symbols are of different types that do not overlap with each other. When a combination of a plurality of types of symbols stopping on the line is an alternative symbol, a plurality of the first selection combinations are provided corresponding to each of the plurality of display columns (R1, R2, R3), The symbols constituting the plurality of first selected combinations corresponding to the display column are common symbols that are the same as the correct combination for the display column, and are different from the correct combination for the other display columns. It is a common pattern且A-option one design, the second selection combination is provided with a plurality to correspond to each of a plurality of display rows, the second selection more in each of the plurality of display rows (R1, R2, R3) the symbol winning combination has become-option one symbol, when the operation sequence of the first stop operation and the second stop operation and pre-determined operating sequence, each of the plurality of pre-determined operating sequence associated with a plurality of winning groups The pre-determining means (101) determines one role group, the determined role group is a correct role, and the symbols constituting the role are the first stop operation in the predetermined operation sequence. One of a plurality of first selected combinations serving as the common symbol for the corresponding display row and a plurality of second selected combinations, and the combination of the combinations constituting the plurality of combination groups are different from each other, and the stop The control means (101) performs the first stop operation order and the first stop of the determined role group When the operation matches, in the display column corresponding to the stop operation means that has received the first stop operation, the common symbol is prioritized over the plurality of second selected combinations, and the drawing of the correct combination and the first selected combination The variable display of the display row is stopped so as to be drawn into the winning line, the predetermined operation order of the determined role group matches the first stop operation, and the predetermined operation order matches the second stop operation. In the display sequence corresponding to the stop operation means that has received the second stop operation and the display sequence corresponding to the stop operation means that has received the third stop operation, the first selection combination and the plurality of second selection combinations The display operation corresponding to the stop operation means that has received the second stop operation and the stop operation that has received the third stop operation so as to prioritize the pulling of the correct answer combination and draw the symbols constituting the correct combination into the winning line When the variable display of the display row corresponding to the row is stopped, the predetermined operation order of the determined role group matches the first stop operation, and the predetermined operation order does not match the second stop operation, the second In the display row corresponding to the stop operation means that has received the stop operation, the selection symbol that constitutes the first selected combination is given priority over the drawing of the first selected combination over the correct combination and the plurality of second selected combinations. If the winning symbol is within the pull-in range, the variable symbol display is stopped so that the alternative symbol is drawn into the winning line, while the alternative symbol constituting the first selection combination is When it is not within the drawing range from the winning line, the variable display of the display row is stopped so that the symbols constituting the correct combination are drawn into the winning line, corresponding to the stopping operation means that has received the second stopping operation You When the alternative symbol constituting the first selected combination in the display row is drawn into the winning line, the alternative constituting the first selected combination is displayed in the display row corresponding to the stop operation means that has received the third stop operation. If the symbol is within the pull-in range from the winning line, the variable symbol display is stopped so that the alternative symbol is pulled into the winning line, while the alternative symbol constituting the first selection combination is stopped. Is not within the pull-in range from the winning line, the variable display of the display column is stopped so as not to win, and the correct combination is displayed in the display column corresponding to the stop operation means that has received the second stop operation. Is drawn into the winning line, the symbol constituting the correct combination is drawn into the winning line in the display column corresponding to the stopping operation means that has received the third stopping operation. In the display row corresponding to the stop operation means that has received the first stop operation, the variable display of the display row is stopped, and the predetermined operation order of the determined role group and the first stop operation do not match. Prioritize the drawing of the plurality of second selected combinations over the correct combination and the first selected combination, and the symbols within the pull-in range from the winning line among the alternative designs constituting each of the plurality of second selected combinations. In the display row corresponding to the stop operation means that has received the third stop operation and the display row corresponding to the stop operation means that has received the second stop operation, the variable display of the display row is stopped so as to be drawn into the pay line The selection of the second selection combination having the possibility of winning by giving priority to the drawing of the second selection combination having the possibility of winning out of the plurality of second selection combinations over the correct combination and the first selection combination. The design is the above When it is within the drawing range from the prize line, the display sequence corresponding to the stopping operation means that has received the second stopping operation and the stopping operation that has received the third stopping operation so that the selected symbol is drawn into the winning line The variable display of the display row corresponding to the means is stopped, and when the alternative symbol constituting the second selection combination that may win a prize is not within the drawing range from the winning line, the second winning combination is set so as not to win. The variable display of the display row corresponding to the stop operation means that has received the 2 stop operation and the display row corresponding to the stop operation means that has received the third stop operation is stopped.

According to the present invention, when the pre-determined operation order matches the actual first stop operation and the second stop operation, the correct combination can always be won, and the pre-determined operation order and the actual first stop operation Are matched and the second stop operation does not match, the correct combination or the first selected combination can be won with a certain probability, and when the predetermined operation sequence and the actual first stop operation do not match The second selection combination can be won with a certain probability.
If the pre-determined operation order matches the first stop operation, the common symbol of the correct answer combination and the first selected combination is drawn into the winning line. Therefore, when the first stop operation ends, both the correct answer combination and the first selected combination About the possibility of winning a prize can be left. If the pre-determined operation order and the second stop operation do not match, the first selected combination is drawn to the winning line in preference to the correct combination. When the symbols constituting the first selected combination are drawn into the winning line, the possibility of winning at the time when the second stop operation ends is that the combination included in the combination determined by the pre-determining means Limited to one choice. The player cannot know which of the plurality of first selected combinations is included in the determined combination. Therefore, there is a possibility that the first selection combination will be missed in the third stop operation. Thereby, even if the first stop operation is correct, if the second stop operation is incorrect, it is possible to make a non-winning with a certain probability.

  In the slot machine described above, the number of the plurality of role groups associated with one predetermined operation order is 4 or more, and the plurality of second selected roles included in each of the plurality of role groups includes a plurality of display columns. In each of (R1, R2, R3), it is preferable that the symbols are different from each other, and the number of the plurality of second selection combinations is two or more. In this case, when the second stop operation is completed, the second selected combination belonging to the determined combination cannot be narrowed down to one, so the player is determined based on which second selected combination. Then, the third stop operation is performed.

Next, in another slot machine according to the present invention, one game is started by consuming game media, and a plurality of display rows (R1, R2, R2) that can cyclically variably display a predetermined number of symbols are displayed. When all the variable displays in R3) are stopped, a winning combination will be given when a combination of a predetermined set of symbols is arranged on the winning line, and a game value corresponding to the type of winning combination is given, and one game is completed. In the slot machine, a pre-determining means (101) for predetermining the types of winning combinations and a plurality of display rows (R1, R2, R3) are provided corresponding to each of the plurality of display columns (R1, R2, R3) A plurality of stop operation means (13a, 13b, 13c) for inputting a stop operation, and a stop operation that has received the stop operation when receiving each stop operation of the plurality of stop operation means (13a, 13b, 13c) means Stop control means (101) for controlling the variable display of the display row corresponding to to move the symbol within the pull-in range which is the maximum number of moving frames to stop, and the combination is selected as a correct combination A combination of a plurality of types of symbols that stop on the winning line, regardless of the timing at which the stop operation is performed in the display row, is a 100% arrangement symbol, and the first stop operation and the second stop operation When the operation order is a pre-determined operation order, a plurality of correct answer combinations are provided corresponding to each of a plurality of display columns (R1, R2, R3), and a plurality of correct answer combinations corresponding to a certain display sequence are provided. The symbols constituting the symbol are alternative symbols for the display column, 100% layout symbols for the other display columns, and are different types of symbols that do not overlap with each other in the display columns. Yo Even if the stop operation at the timing, either as alternative design a set of a plurality of symbols to be stopped on the pay line, said selecting officers, corresponding to each of a plurality of display rows (R1, R2, R3) The plurality of symbols constituting the plurality of selection combinations corresponding to a certain display column are the same as the plurality of correct combinations corresponding to the display column, and the other display columns are alternatively selected. When the predetermined order of operation of the first stop operation and the second stop operation is a predetermined operation order, each of the plurality of predetermined operation orders is associated with a plurality of roles. Of the symbols constituting the plurality of correct combinations and the plurality of selected combinations belonging to each of the plurality of role groups associated with the predetermined operation sequence, the display column corresponding to the selected symbol is the first stop of the predetermined operation sequence The display column corresponds to the operation. The pre-determining means (101) determines one role group, and the determined role group includes a plurality of correct roles and a plurality of selected roles, and constitutes the plurality of role groups. The combinations are different from each other, and the stop control means (101) displays the display corresponding to the stop operation means that has received the first stop when the pre-determined operation order of the determined role group matches the first stop operation. In the column, the variable display of the display column is stopped so that an alternative symbol common to the correct answer combination and the selected combination is drawn into the winning line, and the predetermined operation sequence of the determined role group and the first stop operation are the same. And when the pre-determined operation order and the second stop operation match, in the display row corresponding to the stop operation means that has received the second stop operation and the display row corresponding to the stop operation means that has received the third stop operation, Pull the correct answer from the selected role The display sequence corresponding to the stop operation means that has received the second stop operation and the display sequence corresponding to the stop operation means that has received the third stop operation so as to prioritize and draw the symbols constituting the correct answer combination into the winning line When the variable display is stopped, the predetermined operation order of the determined role group matches the first stop operation, and the predetermined operation order does not match the second stop operation, the stop operation that has received the second stop operation In the display column corresponding to the means, priority is given to the selection of a winning combination with a possibility of winning over the correct answer combination, and when the alternative symbol constituting the selected combination is within the drawing range from the winning line, While the variable display of the display column is stopped so that the selected symbol is drawn into the winning line, if the selected symbol constituting the selected combination is not within the drawing range from the winning line, Possibility of winning in the display row corresponding to the stop operation means that has received the second stop operation by stopping the variable display of the display row so as to draw the 100% correct winning combination symbol to the winning line When a 100% arrangement symbol of a correct answer is drawn into the winning line, a 100% arrangement symbol of the correct answer is drawn into the winning line in the display column corresponding to the stop operation means that has received the third stop operation. When the variable display of the display row is stopped, and an alternative symbol of a selectable winning combination in the display row corresponding to the stop operation means that has received the second stop operation is drawn into the winning line, 3. In the display column corresponding to the stop operation means that has received the stop operation, if the selected symbol constituting the selected combination is within the drawing range from the winning line, the selected figure The variable display of the display column is stopped so as to be drawn into the winning line, and when the alternative symbol constituting the selection combination is not within the drawing range from the winning line, the relevant line is not awarded. When the variable display of the display column is stopped and the pre-determined operation order of the determined role group does not match the first stop operation, the correct combination is displayed in the display column corresponding to the stop operation means that has received the first stop operation. The display row is variable so that drawing of the plurality of selected combinations is prioritized and symbols within the drawing range are drawn from the winning line to the winning line among the alternative symbols constituting each of the plurality of selected combinations. In the display columns corresponding to the stop operation means that has stopped the display and has received the second stop operation and the display columns corresponding to the stop operation means that has received the third stop operation, When the alternative symbol to be configured is within the drawing range from the winning line, a display row corresponding to the stop operation means that has received the second stopping operation so as to pull the alternative symbol into the winning line and a third line The variable display of the display column corresponding to the stop operation means that has received the stop operation is stopped, and if the alternative symbol that constitutes the winning combination that has the possibility of winning is not within the drawing range from the winning line, no winning The variable display of the display row corresponding to the stop operation means that has received the second stop operation and the display row corresponding to the stop operation means that has received the third stop operation are stopped.

According to the present invention, when the pre-determined operation order matches the actual first stop operation and the second stop operation, the correct combination can always be won, and the pre-determined operation order and the actual first stop operation And the second stop operation does not match, the correct combination or selection combination can be won with a certain probability, and there is a case where the predetermined operation sequence and the actual first stop operation do not match The winning combination can be won with a probability.
If the pre-determined operation sequence matches the first stop operation, the common winning symbol and the first selected combination are drawn into the winning line, so when the first stop operation is completed, the correct combination of the correct combination and the selected combination The possibility of winning a prize can be left for both. If the pre-determined operation order and the second stop operation do not match, the selected combination is drawn to the winning line in preference to the correct combination. If the symbols that make up the winning combination are drawn into the winning line, the possibility of winning at the end of the second stop operation remains in the winning combination included in the winning group determined by the predetermining means. Limited. The player cannot know which selected combination is included in the determined combination among a plurality of selected combinations. Therefore, there is a possibility that the selected combination will be missed in the third stop operation. Thereby, even if the first stop operation is correct, if the second stop operation is incorrect, it is possible to make a non-winning with a certain probability.

  In the slot machine described above, the number of the plurality of role groups associated with one predetermined operation order is 4 or more, and the plurality of selected roles included in each of the plurality of role groups includes a plurality of display columns (R1). , R2, R3), it is preferable that the symbols are different from each other, and the number of the selected combinations is two or more. In this case, when the second stop operation is completed, the second selected combination belonging to the determined combination cannot be narrowed down to one, so the player is determined based on which second selected combination. Then, the third stop operation is performed.

  Furthermore, it is preferable that the symbols constituting the plurality of selected combinations are composed of the selected symbols of the plurality of correct combinations in all the display columns. Where the number of symbols that can be arranged in the display row is limited, according to the present invention, the symbols of the selected combination and the correct combination are used in common, so that the arrangement of the symbols can be given a degree of freedom. In addition, even if the symbols constituting the selected combination are drawn into the winning line when the pre-determined operation sequence and the actual first stop operation do not match, the symbols are not included in the determined combination of correct combinations. Since it matches the symbol, it can be unclear whether or not the pressing order was correct when the first stop operation is completed.

In the slot machine described above, in a plurality of predetermined operation sequences in which the first stop operation is the same and the second stop operation is different, a plurality of roles corresponding to one predetermined operation sequence among the plurality of predetermined operation sequences. When a group is a first role group, and a plurality of role groups corresponding to other pre-determined operation orders among the plurality of pre-determined operation orders are second role groups, an arbitrary role of the first role group The group is composed of a correct combination and a selected combination, and an arbitrary combination of the second combination is composed of a correct combination, a selected combination, and a specific combination, and the symbols constituting the specific combination are all displayed. In the column, unlike the symbols constituting the correct combination and the selected combination, the stop control means (101) is a one-time game in which the second combination group is determined by the prior determination means (101). In order not to win the specific role Serial plurality of display rows (R1, R2, R3) preferably by stopping the variable display of.
For example, the small combination X of the second embodiment corresponds to the specific combination. Stop control can be selected depending on whether or not a specific combination is included in the determined combination. For this reason, it is not necessary to determine the stop control independently from the determination of the role group. Note that. The specific combination may be determined by the predetermining unit regardless of the plurality of combination groups.
Moreover, the prior determination means mentioned above may be a lottery means for executing an internal lottery, for example.

In addition, when 10 steps are advanced after detecting the reel position detection signals 155a to 155c, the symbol number PN = 1 is positioned on the winning line L1 in the center of the reel window 20, so that the reel position detection signal If the process proceeds 29 steps after detecting 155a to 155c, the symbol number PN = 2 is positioned on the winning line L1, and if the process advances 48 steps, the symbol number PN = 3 is positioned on the winning line L1, and the process proceeds 390 steps. For example, the symbol number PN = 21 is positioned on the winning line L1. When the processing proceeds beyond step 390, reel position detection signals 155a to 155c are detected again. Accordingly, a predetermined symbol can be positioned on the winning line L1 by the number of steps to be advanced with the timing at which the reel position detection signals 155a to 155c are detected as a base point.

When the payment button 14 is received, if there are game medals for which the winning line is validated and game medals for the stored amount, the return payout process and the payment payout process are performed together.

<A3-2: Slot machine awards and roles>
FIG. 5 is a view for explaining typical prizes and combinations in the slot machine 1 and game values to be given. In the slot machine 1, when a predetermined symbol combination is aligned on the activated pay line, a prize is awarded, and medals are paid out based on the number of payouts determined for each combination. The award includes a small role award that is a payout with a maximum payout of 15 medals, a start award in which the game value given is to start another type of game from the normal game, and a game value to be given There is a replay prize that is to start the next game without betting operation. FIG. 5 shows a small role 01 award through a small role 13 award and a small role A award through a small role H award employed in this embodiment.
Moreover, as a game state employ | adopted by this embodiment, there exists a BB game other than a normal game. When the BB game is won in the BB game in the normal game, the BB game shifts, and when the specified number (for example, 160) is reached, the BB game ends and returns to the normal game.

  The BB Award is a starting prize for starting a BB game. As a combination, a combination of symbols “red 7-red 7-red 7” (also referred to as “red 7 role”), “white 7-white 7-white 7” It consists of a combination of symbols (also referred to as “white 7 role”). When a BB prize is won by an internal lottery during a normal game and a winning combination corresponding to the BB prize is established on the winning line, the BB game is started from the next game. The BB game is ended (for example, 160 cards) when the number of acquired cards in the BB game reaches the specified number or exceeds the specified number by the next payout. If a winning combination corresponding to each prize is not established on the winning line even if the BB prize is won by an internal lottery during the normal game, the winning prize of the BB prize is won until the winning combination is won after the next game. It becomes a BB carryover game that carries over. When the winning combination is established on the winning line during the BB carryover game and the winning is won, the BB game is started from the next game.

  In the slot machine 1, the game type is managed by the game type information. When the game type indicates a BB game, the bit corresponding to the BB game flag in the game type information is set (hereinafter referred to as “setting the BB flag”). When the acquired number of games during the BB game reaches the specified number, the bit is cleared (hereinafter, “BB flag is cleared”). When a plurality of games are mounted, a flag corresponding to each game is provided. If no flag of the game type information is set, it indicates that the game type is a normal game.

In the slot machine 1 of the present embodiment, after the reel stop buttons 13a to 13c are operated, the reels R1 to R3 move within the range of the maximum number of moving frames and stop. In this example, the maximum number of moving frames is 4 frames, which is referred to as a pull-in range.
A symbol that can be stopped on the winning lines L1 to L4 so that a winning can be made no matter what timing the reel stop buttons 13a to 13c are operated is referred to as a 100% winning symbol.
Select a combination of symbols that have different pull-in ranges and that can be stopped on the pay lines L1 to L4 regardless of the timing at which the reel stop buttons 13a to 13c are operated. One pattern.

  As shown in FIG. 5, the small combination includes a correct combination, a first selection combination, and a second selection combination. When the correct answer combination, the plurality of first selection combinations, and the plurality of second selection combinations are made into one combination group, as will be described later, in the internal lottery, a plurality of combination groups having different combinations of combinations are included in the lottery target. A lottery is executed, and one role group is determined by lottery.

The correct answer role is composed of a set of symbols “bell-bell-bell”. In the case of the pay lines L1 to L4 employed in the present embodiment, if the bell symbol stops at either the upper display position U1 or the lower display position D1 in the left reel R1, the correct combination is established. In order to draw the bell symbol to the upper display position U1 or the lower display position D1 no matter what timing the reel stop button 13a is operated, the number of frames between one bell design and the next bell design is within 6 frames. It is necessary to be. As shown in FIG. 3, in the left reel R1, the “bell symbol” is arranged at the symbol numbers PN = 21, 14, and 07. Therefore, in the left reel R1, the bell symbol is a 100% winning symbol.
In the middle reel R2, if the bell symbol stops at the middle display position M2, a correct combination is established. In order to draw a bell symbol to the middle display position M2 no matter what timing the reel stop button 13b is operated, the number of frames between one bell symbol and the next bell symbol is 4 frames (maximum number of moving frames). Must be within. In the middle reel R2, the “bell symbol” is arranged at the symbol numbers PN = 20, 17, 14, 09, 04. Therefore, in the middle reel R2, the bell symbol is a 100% winning symbol.
In the right reel R3, if the bell symbol stops at either the upper display position U3 or the lower display position D3, the correct combination is established. In order to draw the bell symbol to the upper display position U3 or the lower display position D3 no matter what timing the reel stop button 13c is operated, the number of frames between one bell design and the next bell design is within 6 frames. It is necessary to be. As shown in FIG. 3, in the right reel R3, the “bell symbol” is arranged at the symbol numbers PN = 21, 14, and 07. Therefore, in the right reel R1, the bell symbol is a 100% winning symbol.
Thus, in this embodiment, all symbols constituting the correct answer combination are configured with 100% winning symbols.

The first stop operation is referred to as a first stop operation, the second stop operation is referred to as a second stop operation, and the third stop operation is referred to as a third stop operation. Since the slot machine 1 includes the three reel stop buttons 13a to 13c, when the first stop operation and the second stop operation are confirmed, the reel stop button for the third stop operation and the reel to be subjected to stop control are determined. There are six stop operations. In the following description, the operation order of the first stop operation and the second stop operation (substantially including the third stop operation) determined before the player operates is referred to as a predetermined operation order.
One role group determined by the internal lottery is associated with a predetermined operation order. Further, as shown in FIG. 5, the first selected combination is classified for each reel that is the target of the first stop operation in the predetermined operation order.

When the first stop operation is the left reel R1, the small combination 02 to the small combination 05 are associated as the first selection combination. As the symbols constituting the small roles 02 to 05, the bell symbol which is a common symbol with the correct answer is adopted for the left reel R1, and the orange symbol and the apple symbol which are non-common symbols with the correct character are used for the other reels R2 and R3. Adopted.
Focusing on the middle reel R2, as shown in FIG. 6, when the symbols corresponding to the symbol numbers PN = 19 to 09 are located at the middle display position M2, the apple symbol can be drawn into the middle display position M2. On the other hand, when the symbols corresponding to the symbol numbers PN = 21, 20, and 08 to 01 are located at the middle display position M2, the orange symbols can be drawn into the middle display position M2. That is, in the middle reel R2, the apple symbol and the orange symbol constitute an alternative symbol.
Next, focusing on the right reel R3, when the symbol corresponding to the symbol number PN = 19 to 13 is located at the middle display position M3, the apple symbol can be drawn into the upper display position U3 or the lower display position D3. On the other hand, when the symbols corresponding to the symbol numbers PN = 21, 20, and 12-01 are located at the middle display position M3, the orange symbols can be drawn into the middle display position M3. That is, in the right reel R3, the apple symbol and the orange symbol constitute an alternative symbol.
As described above, when the first stop operation is the left reel R1, the symbols constituting the small combinations 02 to 05 as the first selection combination corresponding to this are the symbols of the reel corresponding to the first stop operation as the correct combination. While the common symbol is common, the other reels are non-common symbols and are alternative designs.

In addition, when the first stop operation is the middle reel R2, the small combination 06 to the small combination 09 are associated as the first selected combination. As the symbols constituting the small roles 06 to 09, a bell symbol which is a common symbol with the correct answer combination is adopted for the middle reel R2, and a correct symbol and a non-common symbol are adopted for the other reels R1 and R3, and an alternative symbol is used. A certain orange design and apple design are adopted.
Further, when the first stop operation is the right reel R3, the small combination 10 to the small combination 13 are associated as the first selected combination. As the symbols constituting the small roles 10 to 13, a bell symbol that is a common symbol with the correct answer role is adopted for the right reel R <b> 3, and a symbol that is not common to the correct answer character is used for the other reels R <b> 1 and R <b> 2. A certain orange design and apple design are adopted.
Next, the second selection combination is composed of an ash map symbol and a white map symbol. And in each reel R1-R3, an ash map design and a white map design are alternative designs.

<A4: Operation of slot machine>
Next, details of the overall operation of the slot machine 1 will be described. The CPU 101 performs an initialization process after turning on the power, and executes the process of the flowchart shown in FIG.

<A4-1: 1 game flow>
FIG. 7 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 the insertion bet operation by the medal insertion or the storage bet operation by the operation of the bet button 11 has been performed. (S100). If any signal is detected, the CPU 101 proceeds to the next, determines whether or not the start lever operation has been performed based on the start operation instruction signal 112, and waits until the signal is detected (S101). When the CPU 101 detects the signal, the CPU 101 prohibits the betting operation (S102). 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 (hereinafter, “H” is added to the numerical value shown in hexadecimal), and makes a round in about 1.6 milliseconds. A counter value is acquired from the circuit via the input / output port 107 and is set as a random value (S103). Next, referring to the game type information, a prize lottery table corresponding to the type of the game is selected (S104). Using the selected prize lottery table, the CPU 101 determines which numerical range set for each lottery category on the prize lottery table the acquired random number value belongs to, and the prize corresponding to the lottery category is determined. Lottery information is set (S105). Then, 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 (S106). 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 rotates each of the reels R1 to R3 at a constant rotation speed through an acceleration period of 10 steps. When the pulse widths of the reel drive signals 154a to 154c supplied to the drive signal line of the stepping motor become constant, it is detected that each reel R1 to R3 has reached a constant rotational speed, and the stop buttons 13a to 13c are received. In order to let you know that you can do it, turn on the LED built into the stop button. As another method for detecting that each of the reels R1 to R3 has reached a constant rotational speed, a predetermined step number has elapsed from the start of reel rotation, or a predetermined time has elapsed from the start of reel rotation (predetermined number of interruptions occurred). ) Later, it is assumed 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 reel rotation, or a predetermined time has elapsed since the start of reel rotation (predetermined) After a certain number of interruptions), a method that considers that a certain rotation 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, etc. is there. 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.

  And CPU101 performs the reel stop process which stops each reel R1-R3 (S107). As will be described in detail later, in the reel stop process, when stop operation instruction signals 113a to 113c are detected and the player has operated the stop button, the symbols on the reel obtained at the timing of the stop button operation The symbol to be stopped is determined based on the winning group from the position (symbol number PN). After that, a brake force is applied by all-phase excitation that excites all winding phases simultaneously, and a reel stop process for rotating and stopping by inertia corresponding to 15 steps after starting all-phase excitation is performed for each reel. Do it.

  Next, when all the reels are stopped, the CPU 101 determines whether a winning combination is established on the winning line (S108), and when winning, a game value set for each winning combination is given. Next, the CPU 101 performs a game end determination process, and determines whether the end condition of the BB game is satisfied if the BB game is in progress (S109). Subsequently, lottery information clear processing is performed (S110). Here, if the winning prize in the game is a start prize that can be carried over after the next game (for example, the BB prize), the lottery information is cleared only when the prize is won, and the prize is lost without winning. Does not clear the lottery information. On the other hand, if the winning prize in the game is a start prize or small role prize that cannot be carried over, the lottery information is cleared regardless of winning or missing. Next, the prohibition of the betting operation performed in step S102 is canceled (S111), the game medal can be inserted or the input of the bet button 11 can be accepted, and the process returns to step S100 to prepare for the start of the next game. Note that the process from the acceptance of the bet operation in step S100 to the release of the bet operation prohibition in step S111 is referred to as one game in the slot machine 1.

<A4-2: Contents of role group>
FIG. 8 is an explanatory diagram showing a part of the lottery object of the internal lottery executed in steps S104 and S105. As shown in this figure, a plurality of role groups (four role groups in this example) are associated with each of the six pre-determined operation orders. In the internal lottery, 24 role groups A1 to I4, B1 to B4, C1 to C4, D1 to D4, E1 to E4, and F1 to F4 are included in the lottery targets. Therefore, the lottery probability of each role group is equal. When a certain role group is determined by lottery, the small roles included in the role group are simultaneously selected, and the predetermined operation order is also determined according to the determined role group. Further, the combinations of the small roles constituting the 24 role groups are different from each other.
For example, the pre-determined operation order “left → middle → right” is associated with the role groups A1 to A4. In addition, the role group a1 includes a correct combination, a small combination 02 as a first selection combination, and a small combination A and B as a second selection combination.
FIG. 9 shows the structure of the role group structure. First, one common correct combination is included in the four combination groups for a certain predetermined operation order. Next, the role group includes one first selected combination in which the correct answer combination and the design are common to the reels that are the targets of the first stop operation in the predetermined operation sequence, and the correct answer combination and the design are different for the other reels. It is. Further, the role group includes two second selected roles. The two second selected combinations are composed of alternative symbols having different symbols constituting the combination for all reels.

<A5: Stop control>
The stop control when any of the role groups is determined by the internal lottery will be described. In this example, it is assumed that the role group 1 having “previous operation order from“ left → middle → right ”” is determined by lottery. The role group a1 includes a correct answer role, a small role 02 as the first selected role, and a small role A and a small role B as the second selected role.

<A5-1: When the first stop operation matches the pre-determined operation order>
First, when the player's first stop operation is the left reel R1, that is, when the first stop operation in the pre-determined operation sequence of the role group 1 determined by the lottery matches the actual first stop operation. As shown in FIG. 10, in the left reel R1, the CPU 101 executes stop control so as to stop the bell symbols on the winning lines L1 to L4. In this case, the bell symbol, which is a common symbol for the correct answer combination and the first selected combination, is given priority over the second selected combination (gray map or white map) and drawn into the winning line. Here, since the bell symbol is a 100% winning symbol, the bell symbol is stopped at the upper display position U1 or the lower display position D1. In the illustrated example, the bell symbol is drawn into the upper display position U1. At this point, the winning line is limited to L1 and L3.

<A5-1-1: When the first stop operation and the second stop operation coincide with the predetermined operation order>
Next, when the player's second stop operation is the middle reel R2, that is, the second stop operation in the pre-determined operation sequence of the role group 1 determined by lottery matches the actual second stop operation. In this case, the CPU 101 executes stop control so that the bell symbol is stopped at the winning line L1 or L3 in the middle reel R2. In this case, the correct combination is prioritized over the first selection combination and the second selection combination and is drawn into the winning line L1 or L3. Here, since the bell symbol is a 100% winning symbol, the bell symbol is stopped at the middle display position M2. When employing the table control, the CPU 101 selects a stop table for drawing a bell symbol from a plurality of stop tables, refers to the stop table, acquires the number of moving frames, and stops the middle reel R2. On the other hand, when the control control is employed, the CPU 101 detects the rotational phase of the middle reel R2, obtains the number of moving frames for stopping the bell symbol at the middle display position M2 based on the detection result, and obtains the number of obtained moving frames. Then, the middle reel R2 is stopped.
Further, in the third stop operation, the correct answer combination is prioritized over the first selected combination and the second selected combination and is drawn into the pay lines L1 and L3. That is, the CPU 101 stops the bell symbol at the upper display position U3 or the lower display position D3. As described above, when the predetermined operation order matches the actual operation order, the correct answer combination is awarded with a probability of 100%.

<A5-1-2: When the first stop operation matches the predetermined operation order, and the second stop operation does not match the predetermined operation order>
On the other hand, when the first stop operation of the player is the left reel R1 and the second stop operation is the right reel R3, that is, the second stop operation in the predetermined operation sequence of the role group 1 determined by lottery and A case where the actual second stop operation does not match will be described with reference to FIG. When the first stop operation is completed, the possibility of winning is limited to the correct combination and the first selection combination. In the right reel R3, the orange symbol of the small role 02 is not a 100% winning symbol. Of the total drawing range, the orange drawing range (a) is the range in which the orange symbols are drawn to the maximum within the drawing range that is the maximum number of moving frames (four frames).

  In the right reel R3, the CPU 101 executes stop control so that the orange symbol of the first selected combination is stopped on the winning line L1 or L3 rather than the bell symbol of the correct combination and the symbol of the second selected combination. Since the orange symbol is not a 100% winning symbol in the right reel R3, the orange symbol cannot be pulled into the upper display position U3 or the lower display position D3 depending on the operation wing. In this case, the bell symbol is drawn into the upper display position U3 or the lower display position D3. That is, when the orange symbol which is the alternative symbol constituting the first selection combination is within the drawing range from the winning line, the CPU 101 stops the right reel R3 so as to pull the orange symbol into the winning line. When the symbol is not within the drawing range from the winning line, the right reel R3 is stopped so that the bell symbol constituting the correct combination is drawn into the winning line.

  When table control is employed, a selection table for specifying a stop table to be selected is provided according to the operation timing of the reel stop button 13c. In this selection table, information specifying a stop table for stopping the orange symbol at the upper display position U3 or the lower display position D3 in association with the pull-in range (a) is stored, and in the pull-in range (b)-(a). Corresponding information for specifying a stop table for stopping the bell symbol at the upper display position U3 or the lower display position D3 is stored. The CPU 101 refers to the selection table, identifies the stop table, and executes stop control using the identified stop table. On the other hand, when adopting control control, the CPU 101 pulls the orange symbol into the upper display position U3 or the lower display position D3 in the pull-in range (a), and the bell symbol in the upper display position in the pull-in range (b)-(a). Stop at U3 or lower display position D3.

Next, stop control of the third stop operation will be described with reference to FIG. First, it is assumed that the bell symbol is stopped at the upper display position U1 of the left reel R1 by the first stop operation, and the orange symbol is stopped at the upper display position U3 of the right reel R3 by the second stop operation. In this state, the player can know which of the first selection combination, the small combination 02 “Bellow Orange-Orange”, or the first selection combination, the small combination 04 “Bell Apple Orange”. Can not. A player who knows the combination of symbols of the first selection combination knows that the first selection combination is tempered at this point, and thus notices that the pressing order is wrong. However, since it is not known which of the small role 02 and the small role 04 is won, the player will select an orange symbol or an apple symbol for intuition, and will press it.
If you look for the orange symbol, you can win the small role 02 “Belle Orange-Orange”. On the other hand, in the middle reel R2, the orange symbol and the apple symbol constitute an alternative symbol. It will spill.
That is, when the orange symbol which is the alternative symbol constituting the first selection combination is within the drawing range from the winning line, the CPU 101 stops the middle reel R2 so as to pull the orange symbol into the winning line. If the symbol is not within the drawing range from the winning line, the middle reel R2 is stopped so as not to win.

  Next, when the bell symbol is stopped at the upper display position U1 of the left reel R1 in the first stop operation, and the bell symbol is stopped at the upper display position U3 of the right reel R3 in the second stop operation, The possibility of winning is limited to correct answers. Since the bell symbol is a 100% winning symbol in the middle reel R2, the CPU 101 executes stop control so as to stop the bell symbol at the middle display position M2 no matter what timing the reel stop button 13b is operated.

<A5-2: When the first stop operation does not match the predetermined operation order>
A case where the player's first stop operation is the middle reel R2 will be described with reference to FIG. When the first stop operation in the pre-determined operation order of the role group a1 determined by the lottery does not match the actual first stop operation, the CPU 101 configures the small role A that is the second selected role in the middle reel R2. The drawing of the gray map symbol and the white map symbol constituting the small combination B has priority over the pulling of the bell symbol constituting the correct combination and the orange symbol constituting the first selection combination. Since the ash map design and the white map design are alternative arrangements in the first place, there is no priority relationship. Therefore, the CPU 101 stops either the gray map symbol or the white map symbol at the middle display stop position M2 in response to the stop operation of the reel stop button 13b. That is, the CPU 101 stops the middle reel R2 so as to draw the symbols within the drawing range from the winning line among the alternative symbols (the ash map symbol and the white map symbol) constituting each of the plurality of second selection combinations into the winning line. .

  When table control is employed, a selection table for specifying a stop table to be selected is provided according to the operation timing of the reel stop button 13b. In this selection table, information specifying a stop table for stopping the ash map symbol at the middle display position M2 is stored in association with the pull-in range (a), and the white map symbol is correlated with the pull-in range (b). Information for specifying a stop table to be stopped at the display position M2 is stored. The CPU 101 refers to the selection table, identifies the stop table, and executes stop control using the identified stop table. On the other hand, when adopting the control control, the CPU 101 pulls the gray map symbol into the middle display position M2 in the pull-in range (a) and stops the white map symbol in the middle display position M2 in the pull-in range (b).

When the ash map symbol is stopped at the middle display position M2 by the first stop operation, the possibility of winning is limited to the small combination A. However, even if the player finds that the first stop operation is inconsistent with the predetermined operation order, the player knows which of the small combination A, small combination C, small combination F, and small combination H is won. I can't.
In addition, when the white map symbol is stopped at the middle display position M2 by the first stop operation, the possibility of winning is limited to the small combination B. However, even if the player finds that the first stop operation is inconsistent with the predetermined operation order, the player knows which of the small role B, the small role D, the small role E, and the small role G is won. I can't.

The stop control of the second stop operation will be described with reference to FIG. In this example, it is assumed that the left reel R1 is stopped by the second stop operation.
First, when the player stops the ash map symbol in the left reel R1 when the ash map symbol is stopped at the middle display position M2 by the first stop operation, the CPU 101 displays the ash map symbol in the upper display position U1 or the lower step. Pull to display position D1. On the other hand, when the player hits the white map symbol, the CPU 101 kicks the white map symbol and performs control so that the white map symbol does not stop at the upper display position U1 or the lower display position D1. In this case, the gray map symbol and the white map symbol constitute an alternative symbol in the left reel R1, and the CPU 101 executes stop control so as to allow the winning of the small role A and not allow the winning of any other role. Because. When the ash map symbol is drawn into the upper display position U1 or the lower display position D1, the possibility of winning the small role A remains. On the other hand, when the ash map symbol is not drawn into the upper display position U1 or the lower display position D1, the third stop operation is not waited and the non-winning is determined.

Here, it is assumed that the ash map symbol is drawn into the middle display position M2 in the middle reel R2. In this case, in the left reel R1 and the middle reel R2, the ash map symbols are stopped on the pay lines L1 and L3. In this state, for a player who cannot determine which group the result of the internal lottery is, there is a possibility of winning a prize. “Ash map” and small role C “Ash map—Ash map—White map”. However, the player does not know whether the small role A or the small role C is won. Therefore, in the third stop operation, the player relies on intuition to push forward.
If a player who has a pressing skill operates the reel stop button 13c aiming at the ash map symbol, the small role A can be won. On the other hand, when a white map symbol is pressed for, it is not won. The same applies when the white map symbol stops at the middle display position M2 in the first stop operation.
In other words, in the second stop operation (left reel) and the third stop operation (right reel), the CPU 101 selects the second selected combination having a possibility of winning a prize among the plurality of second selected combinations from the correct combination and the first selected combination. Prioritize pulling. When the alternative symbol constituting the second selective combination having the possibility of winning is within the drawing range from the winning line, the left reel R1 and the second reel R1 in the second stop operation so as to draw the alternative symbol into the winning line. 3. When the right reel R3 of the stop operation is stopped, and the alternative symbol constituting the second selection combination that has the possibility of winning is not within the drawing range from the winning line, the left reel R1 and the right reel are set so as not to win. The reel R3 is stopped.

<A5-3: Relationship between stop operation and winning probability>
Next, the relationship between the stop operation and the winning probability will be described with reference to FIG. First, when the pre-decision operation order matches the actual stop operation order, the bell symbols constituting the correct combination are drawn in the reels R1 to R3. Here, the bell symbol is a 100% winning symbol in all reels R1 to R3. For this reason, if the pre-decision operation order matches the actual stop operation order, the correct answer combination is awarded 100%.
Next, the first stop operation was the left reel R1 and the second stop operation was the right reel R3, the first stop operation was in agreement with the predetermined operation sequence, and the second stop operation was inconsistent with the predetermined operation sequence. Assume a case. In this case, since the orange symbol constituting the first selection combination is drawn with priority over the bell symbol, the bell symbol stops at the upper display position U3 or the lower display position D3 with a probability of 50%, and with a probability of 50%. The orange symbol stops at the upper display position U3 or the lower display position D3. Then, when the bell symbol is drawn into the winning line, the winning combination having a possibility of winning is limited to the correct winning combination. In this case, the CPU 101 pulls the bell symbol constituting the correct combination in the third stop operation to the middle display position M2. In the middle reel R2, the bell symbol is a 100% winning symbol, so it will be won. That is, the probability of winning the correct combination when the second stop operation does not match the predetermined operation order is 50%.
On the other hand, when the orange symbol is drawn into the upper display position U3 or the lower display position D3 in the second stop operation, there is a possibility that a player who cannot specify the result of the internal lottery in any one role group will win a prize visually. As a role, there are a small role 02 “bell-orange-orange” and a small role 04 “bell-apple-orange”. For this reason, in the third stop operation, the probability of winning the small role 02 is 25%. Therefore, when it matches with the predetermined stop operation sequence until the first stop operation, the probability of winning a small combination is 75%.
Furthermore, when the first stop operation is the middle reel R2 or the right reel R3 and the order of operation determined from the first stop operation is different from the pre-determined operation order, each wins a small role with a probability of 25%.

  Thus, when the first stop operation does not match, the winning probability is 25%, and when the first stop operation matches and the second stop operation does not match, the winning probability is 75%, and the first stop operation and When the second stop operation matches, the winning probability is 100%. That is, according to the slot machine of the first embodiment, it is possible to increase the winning probability as the degree of coincidence between the predetermined operation sequence and the actual stop operation sequence increases.

<B. Second Embodiment>
In the above-described first embodiment, the lottery is executed by including a plurality of role groups associated with the respective predetermined determination operation orders in the lottery object of the internal lottery. One group includes one correct combination, one first selection combination, and a plurality of second selection combinations. When the predetermined operation order matches the first stop operation and the second stop operation, the correct combination is drawn into the winning line, and the predetermined operation order matches the first stop operation and the second stop operation does not match , The first selected combination with correct answer or missed is drawn into the winning line, and the second selected combination with missing is drawn into the winning line when the predetermined operation sequence and the first stop operation do not match.
On the other hand, the slot machine 1 according to the second embodiment includes two correct combinations and two selection combinations in one combination group. Further, the slot machine 1 according to the second embodiment is the same as the slot machine 1 according to the first embodiment, except for the arrangement of symbols of the reels R1 to R3, the composition of the winning combination, the winning line, and the content of stop control. It is configured.
As shown in FIG. 16, the winning line L5 of the present embodiment is a middle winning line L5. The middle reel display position M1 of the left reel R1, the middle deck display position M2 of the middle reel R2, and the middle deck display position M3 of the right rail R3. Consists of.

<B1: Composition of roles>
FIG. 17 shows a part of the combination employed in the slot machine 1 according to the second embodiment, and FIG. 18 shows the symbol arrangement of each reel. As shown in this figure, the correct combination includes small combination 01 to small combination 28, and the selected combination includes small combination A to small combination H. The correct combination is classified by three reels R1 to R3 that are targets of the first stop operation in the predetermined stop operation order.
In the following description, a combination of a plurality of types of symbols that can be drawn on a winning line regardless of the wing of any reel on a certain reel is referred to as a 100% arrangement symbol. As described above, the alternative symbol is a set of symbols in which the pull-in ranges do not overlap, but the pull-in ranges may overlap in the 100% arrangement symbols. The 100% arrangement symbol is a concept including an alternative symbol.

As a correct answer combination in which the left reel R1 is a first stop operation, a small combination 01 to a small combination 08 are associated. The symbols constituting the small role 01 to the small role 08 coincide with the symbols constituting the small role A to the small role H that are the selected combinations for the left reel R1.
Here, the symbols of the left reel R1 constituting the small roles 01 to 08 are a white plum symbol and an ash plum symbol. As shown in FIG. 17, the white plum symbol is arranged at the symbol number PN = 21,08,03, and the ash plum symbol is arranged at the symbol number PN = 16,13. In the left reel R1, the white plum design and the ash plum design are alternative designs.
Further, the symbols of the medium reel R2 constituting the small roles 01 to 08 are a white map symbol and a cherry symbol. The white map symbol is arranged at symbol number PN = 19, 14, 04, 01, and the cherry symbol is arranged at symbol number PN = 09. In the middle reel R2, the white map symbol and the cherry symbol are 100% arrangement symbols.

In the right reel R3, the white plum symbol and the ash plum symbol are 100% arrangement symbols. In the following description, the small combination 01 to small combination 08 are collectively referred to as a correct combination (left).

Next, the small combination 09 to the small combination 16 are associated with each other as the correct combination with the middle reel R2 as the first stop operation. The symbols composing the small roles 09 to 16 match the symbols composing the small roles A to H which are the selected combinations for the middle reel R2.
Here, the symbols of the left reel R1 constituting the small roles 09 to 16 are a white bell symbol and an ash bell symbol. As shown in FIG. 18, the white bell symbol is arranged at the symbol number PN = 09, 04, 01, and the gray bell symbol is arranged at the symbol number PN = 17, 14. In the left reel R1, the white bell symbol and the gray bell symbol are 100% arrangement symbols.
Further, the symbols of the middle reel R2 constituting the small roles 09 to 16 are a white bell symbol and an ash bell symbol. The white bell symbol is arranged at the symbol number PN = 15,10, and the gray bell symbol is arranged at the symbol number PN = 20,05,02. In the middle reel R2, the white map design and the gray bell design are alternative designs.
Further, the symbols of the right reel R3 constituting the small roles 09 to 16 are a white bell symbol and an ash bell symbol. The white bell symbol is arranged at the symbol number PN = 19, 15, 05, 01, and the gray bell symbol is arranged at the symbol number PN = 10. In the right reel R3, the white bell symbol and the gray bell symbol are 100% arrangement symbols. In the following description, the small combinations 09 to 16 are collectively referred to as correct combinations (medium).

Next, the small combination 17 to the small combination 28 are associated with each other as the correct combination with the right reel R3 as the first stop operation. The symbols constituting the small combination 17 to the small combination 28 coincide with the symbols configuring the small combination A to the small combination H which are the selected combinations for the right reel R3.
Here, the symbols of the left reel R1 constituting the small roles 17 to 28 are a watermelon symbol, a red seven symbol, and a white map symbol. As shown in FIG. 18, the watermelon symbol is arranged at symbol number PN = 18, 15, 11, 07, 02, the red 7 symbol is arranged at symbol number PN = 05, and the white map symbol is symbol number PN = 10. 06. In the left reel R1, the watermelon symbol, the red 7 symbol, and the white map symbol are 100% arrangement symbols.
Further, the symbols of the middle reel R2 constituting the small roles 17 to 28 are a watermelon symbol and a white plum symbol. The watermelon symbol is arranged at the symbol number PN = 16,11, and the white plum symbol is arranged at the symbol number PN = 21,06,03. In the middle reel R2, the watermelon symbol and the white map symbol are 100% arrangement symbols.
Further, the symbols of the right reel R3 constituting the small roles 17 to 28 are a cherry symbol and a white map symbol. The cherry symbol is arranged at symbol number PN = 20, 16, 06, 02, and the white map symbol is arranged at symbol number PN = 11.

  In addition, the small combination A to H which is a selection combination is composed of a white plum design and an ash plum design for the left reel R1 and has the same design as the selection combination corresponding to the left reel R1 (small combination 01 to 08). The reel R2 is composed of a white bell symbol and an ash bell symbol, and the symbol corresponding to the middle reel R2 (small roles 09 to 16) and the symbol are common, and the left reel R1 is composed of a white map symbol and a cherry symbol. The symbols are common to the selected combination (small combination 07 to small combination 28) corresponding to the reel R3.

<B2: Role group contents>
FIG. 19 is an explanatory diagram showing a part of the lottery object of the internal lottery. As shown in this figure, a plurality of role groups (four role groups in this example) are associated with each of the six pre-determined operation orders. In the internal lottery, 24 role groups A1 to I4, B1 to B4, C1 to C4, D1 to D4, E1 to E4, and F1 to F4 are included in the lottery targets. Therefore, the lottery probability of each role group is equal. When a certain role group is determined by lottery, small roles included in the role group are simultaneously selected. Further, the combinations of the small roles constituting the 24 role groups are different from each other.

  For example, the pre-determined operation order “left → middle → right” is associated with the role groups A1 to A4. In addition, the role group A1 includes the correct answer role (left) and the role group G1 as the selected role. Here, in the role group G1, the small role A and the small role B, in the role group G2, the small role C and the small role D, in the role group G3, the small role E and the small role F, in the role group G4, Small role G and small role H, small role A, small role B and small role X in role group G1 ′, small role C, small role D and small role X in role group G2 ′, role group G3 ′ Includes a small role E, a small role F, and a small role X, and a role group G4 ′ includes a small role G, a small role H, and a small role X, respectively. If the role group including any of the role groups G1 ′ to G4 ′ among the role groups shown in FIG. 19 is determined as a result of the internal lottery, the small role X “Watermelon-Watermelon-Watermelon” is never included. Don't win. The reason why the small role X is simultaneously won in the role group including any one of the role groups G1 ′ to G4 ′ is to make the pre-determined operation order different from the role group including any one of the role groups G1 to G4. is there. Specifically, the role group A1 and the role group B1 differ in whether or not the small role X is included as a simultaneous winning combination, and the pre-determined operation order corresponding to the role group A1 is “left While “→ middle → right”, the pre-determined operation order corresponding to the role group 1 is “left → right → middle”. In this way, as a combination that is won simultaneously in order not to win a prize in order to change the pre-determined operation order, apart from the role group shown in FIG. 19, the result of the internal lottery does not correspond to the pre-determined operation order. It is preferable to use a combination. For example, as a result of the internal lottery, there may be a case where only the small role X is won, and when only the small role X is won, the watermelon symbol is drawn into the winning line according to the timing of the player's stop operation. There is a possibility of winning a combination X, but if a group including any of the combination groups G1 ′ to G4 ′ is determined among the combinations shown in FIG. It is not allowed to.

  FIG. 20 shows the structure of the role group configuration. First, a common correct combination group is included in the four combination groups for a certain predetermined order of operation. The correct answer combination group corresponds to the first stop operation, and includes a correct answer combination (left), a correct answer combination (middle), and a correct answer combination (right). Next, the role group includes at least two selected roles. The symbols constituting the two selected combinations are composed of alternative symbols in each reel, and the reel corresponding to the first stop operation in the predetermined operation sequence is common to the correct combination included in the combination group. It is an alternative design.

  For example, in the role group 1 corresponding to the predetermined operation order in which the first stop operation is the left reel R1 and the second stop operation is the middle reel R2, the correct combination (left), the small combination A and the small combination B as the selection combination including. Here, the symbols of the left reel R1 corresponding to the first stop operation in the correct combination (left) are the white plum symbol and the ash plum symbol, which are the symbols of the small reel A1 and the small reel B left reel R1. It is common. Further, the symbols of the middle reel R2 of the small role A and the small role B are a white bell symbol and an ash bell symbol, and the symbols of the right reel R3 are a white map symbol and a cherry symbol, which are alternative symbols.

  In addition, the role group 1 corresponding to the predetermined operation order in which the first stop operation is the left reel R1 and the second stop operation is the right reel R3 is the correct combination (left), the small combination A as the selection combination, and the small combination B. And including watermelon. As described above, for the small combination A and the small combination B, the symbol of the left reel R1 is common to the correct combination (left), and the middle reel R2 and the right reel R3 are configured with alternative symbols.

<B5: Stop control>
The stop control when any of the role groups is determined by the internal lottery will be described. In this example, it is assumed that the role group 1 having “previous operation order from“ left → middle → right ”” is determined by lottery. The role group a1 includes a correct role (left) and a small role A and a small role B as selected roles.

<B5-1: When First Stop Operation Matches Predetermined Operation Order>
First, when the player's first stop operation is the left reel R1, that is, when the first stop operation in the pre-determined operation sequence of the role group 1 determined by the lottery matches the actual first stop operation. As shown in FIG. 21, the CPU 101 executes stop control so that one of the white plum symbol and the ash plum symbol is stopped on the winning line L5 in the left reel R1. Since the white plum symbol and the ash plum symbol constitute an alternative symbol, and the symbol is common to the correct answer combination and the selection combination, either one is displayed in the middle even if the reel stop button 13a is operated at any timing. It can be pulled into position M2. In this example, it is assumed that the white plum symbol is drawn into the winning line L5.
In this case, of the combinations constituting the combination group 1, winning combinations are limited to the small combination 01 to the small combination 04 and the small combination A.

<B5-1-1: When the first stop operation and the second stop operation coincide with the predetermined operation order>
Next, when the player's second stop operation is the middle reel R2, that is, the second stop operation in the pre-determined operation sequence of the role group 1 determined by lottery matches the actual second stop operation. In this case, the CPU 101 executes stop control so that the white map symbol and the cherry symbol, which are 100% arrangement symbols, are stopped on the winning line L5 in the middle reel R2. In this case, the correct answer combination is prioritized over the selected combination and drawn into the winning line L5. Here, since the white map symbol and the cherry symbol are 100% arrangement symbols, either one is stopped at the middle display position M2. When adopting table control, the CPU 101 selects a stop table that draws 100% placement symbols from among a plurality of stop tables, obtains the number of moving frames by referring to the stop table, and stops the middle reel R2. Let On the other hand, when adopting the control control, the CPU 101 detects the rotation phase of the middle reel R2, obtains the number of moving frames for stopping the 100% arrangement symbol at the middle display position M2 based on the detection result, and obtains the obtained movement. The middle reel R2 is stopped according to the number of frames.
Further, in the third stop operation, the correct combination is prioritized over the selected combination and drawn into the winning line L5. In this example, it is assumed that the white map symbol is stopped at the winning line L5 by the second stop operation. In this case, it is the small combination 01 and the small combination 03 that have the possibility of winning. The right reel symbol of the small role 01 and the right reel symbol of the small role 03 constitute a 100% arrangement symbol, so that no matter which timing the reel stop button 13c is operated, the small role 01 or the small role 03 is won. Can be made. As described above, when the predetermined operation order matches the actual operation order, the correct answer combination is awarded with a probability of 100%.

<B5-1-2: When the first stop operation matches the predetermined operation order, and the second stop operation does not match the predetermined operation order>
Next, referring to FIG. 22, when the player's first stop operation is the left reel R1 and the second stop operation is the right reel R3, that is, the role group 1 determined in advance by lottery is determined. A case is assumed where the second stop operation in the operation order and the actual second stop operation do not match.
The right reel symbols of the small roles 01 to 04 are a white plum symbol and an ash plum symbol, and these are 100% arrangement symbols. On the other hand, the small reel A's right reel symbol is a white map symbol. In the right reel R3, the white map symbol is not a 100% winning symbol. Of the total drawing range, the range in which the white map symbol can be drawn to the maximum within the drawing range that is the maximum number of moving frames (four frames) is the white map symbol drawing range (a).
In this case, the white map symbol of the winning combination that has the possibility of winning is given priority over the 100% arrangement symbol (ash plum or white plum) constituting the correct combination and drawn into the winning line L5.
When table control is employed, a selection table for specifying a stop table to be selected is provided according to the operation timing of the reel stop button 13a. In this selection table, information specifying a stop table for stopping the white map symbol at the middle display position M3 is stored in association with the pull-in range (a), and ashes are stored in correspondence with the pull-in range (b)-(a). Information for specifying a stop table for stopping the plum symbol or the white plum symbol at the middle display position M3 is stored. The CPU 101 refers to the selection table, identifies the stop table, and executes stop control using the identified stop table. On the other hand, when the control control is adopted, the CPU 101 draws the white map symbol in the middle display position M3 in the pull-in range (a), and displays the white map symbol or the gray map symbol in the middle range in the pull-in range (b)-(a). Stop at position M3.
That is, when the white map symbol that is the alternative symbol constituting the selection combination is within the drawing range from the winning line, the CPU 101 stops the right reel R3 so as to pull the white map symbol into the winning line. If the map symbol is not within the drawing range from the winning line, the right reel R3 is stopped so that a 100% correct symbol having a possibility of winning is drawn into the winning line.

First, in the right reel R3, it is assumed that the white map symbol is drawn into the winning line L5 by the second stop operation. As shown in FIG. 23, in this state, the possibility of winning is limited to the small combination A which is the selected combination. However, even if the player finds that the first stop operation is inconsistent with the predetermined operation order, the player has won the small role A “white plum-white bell-white map” or the small role D “white plum”. I don't know if "Gray Bell-White Map" is won.
A player who knows the combination of symbols of the selected role knows that the selected role is the tempered at this point. To do. However, since the selection combination is common in the order of full depression, it is not known which is wrong between the first stop operation and the second stop operation.
In the third stop operation, if the player presses the white bell symbol of the middle reel R2, the small combination A can be won. On the other hand, if the ash bell symbol is pressed for, it is not won. This is because in the middle reel R2, the white bell design and the gray bell design constitute an alternative design. That is, when the white bell symbol that is an alternative symbol constituting the selection combination is within the drawing range from the winning line, the CPU 101 stops the middle reel R2 so that the white bell symbol is drawn into the winning line, and the white bell is stopped. If the symbol is not within the drawing range from the winning line, the middle reel R2 is stopped so as not to win.

Next, in the right reel R3, it is assumed that the white map symbol is missed by the second stop operation and the white plum symbol is drawn into the winning line L5. In this case, it is the small role 01 “white plum-white map-white plum” and the small role 02 “white plum-cherry-white plum” that are correct answers that have the possibility of winning.
In the middle reel R2 that is the target of the third stop operation, the white map symbol and the cherry symbol constitute a 100% arrangement symbol. For this reason, no matter what timing the player operates the reel stop button 13b, the small combination 01 or small combination 02 is won.

<B5-2: When the first stop operation does not match the predetermined operation order>
A case where the player's first stop operation is the middle reel R2 will be described with reference to FIG. When the first stop operation in the pre-determined operation order of the role group a1 determined by the lottery and the actual first stop operation do not match, the CPU 101 configures the white bell that constitutes the small role A that is the selected role in the middle reel R2. The drawing of the gray bell symbol constituting the symbol and the small combination B is given priority over the drawing of the 100% arrangement symbol constituting the correct combination. There is no priority relationship between the white bell design and the gray bell design because they are an alternative arrangement in the first place. Accordingly, in response to the stop operation of the reel stop button 13b, the CPU 101 stops either the white bell symbol or the gray bell symbol at the middle display stop position M2. That is, the CPU 101 stops the middle reel R <b> 2 so as to draw the symbols within the drawing range from the winning line among the alternative symbols constituting each of the plurality of selection roles to the winning line.

  When table control is employed, a selection table for specifying a stop table to be selected is provided according to the operation timing of the reel stop button 13b. In this selection table, information specifying a stop table for stopping the white bell symbol at the middle display position M2 is stored in association with the pull-in range (a), and the gray bell symbol is associated with the pull-in range (b). Information for specifying a stop table to be stopped at the display position M2 is stored. The CPU 101 refers to the selection table, identifies the stop table, and executes stop control using the identified stop table. On the other hand, when the control control is employed, the CPU 101 pulls the white bell symbol into the middle display position M2 in the pull-in range (a) and stops the gray bell symbol in the middle display position M2 in the pull-in range (b).

When the white bell symbol is stopped at the middle display position M2 by the first stop operation, the possibility of winning is limited to the small combination A. However, the player cannot know whether the first stop operation matches or does not match the predetermined operation order. This is because the middle reel symbol of the correct answer (medium) is composed of a white bell symbol and an ash bell symbol (see FIG. 17).
In this state, the player who cannot identify the result of the internal lottery as any one of the role groups can understand that the correct role (medium) is the small role 09, the small role 10 and the small role in which the middle reel symbol is a white bell symbol. There is a possibility that the combination 13 and the small combination 14 and the small combination A, the small combination C, the small combination F and the small combination H in which the middle reel symbol is a white bell among the selected combinations may be won. It is.

  On the other hand, when the gray bell symbol is stopped at the middle display position M2 by the first stop operation, only the small combination B has a possibility of winning. However, the player can play the small role 11, the small role 12, the small role 15 and the small role 16 in which the middle reel symbol is the gray bell symbol among the correct answers (medium), and the middle reel symbol is the gray bell symbol among the selected roles. It is not known which of the small role B, the small role D, the small role E, and the small role G that are won.

The stop control of the second stop operation will be described with reference to FIG. In this example, it is assumed that the left reel R1 is stopped by the second stop operation.
First, when the white bell symbol is stopped at the middle display position M2 by the first stop operation and the player presses the white plum symbol on the left reel R1, the CPU 101 pulls the white plum symbol to the middle display position M1. . On the other hand, when the player hits the ash plum symbol, the non-winning is confirmed. In this case, the ash plum symbol and the white plum symbol constitute an alternative symbol in the left reel R1, and the CPU 101 executes stop control so as to allow the winning of the small role A and not allow the winning of the other role. Because. When the white plum symbol is drawn into the middle display position M1, the possibility of winning the small role A remains. On the other hand, when the white plum symbol is not drawn into the middle display position M1, the third stop operation is not waited and the non-winning is confirmed.

Here, it is assumed that the white plum symbol is drawn into the middle display position M1 in the left reel R1. In this case, in the left reel R1 and the middle reel R2, the white plum symbol and the white bell symbol are arranged on the winning line L5. The player who knows the combination of symbols of the selected role knows that the selected role is the tempered at this point, so he notices that the pressing order is wrong, and selects and pushes for the selected role. . However, since the selection combination is common in the order of full depression, it is not known which is wrong between the first stop operation and the second stop operation.
Also, in this state, there is a possibility of winning a prize among the selected roles of the small role A “white map-white bell-white map” and the small role C “white plum-white bell-cherry”. However, the player does not know whether the small role A or the small role C is won. Therefore, in the third stop operation, the player relies on intuition to push forward.
If a player who has a pressing skill operates the reel stop button 13c aiming at a white map symbol, the small role A can be won. On the other hand, if you hold down the cherry pattern, you will not win. In other words, the CPU 101 determines that, in the left reel R1 for the second stop operation and the right reel R3 for the third stop operation, the alternative symbol that constitutes the winning combination that has a possibility of winning is within the drawing range from the winning line. The left reel R1 and the right reel R3 are stopped so that the selected symbol is drawn into the winning line, and when the selected symbol constituting the winning combination that has a possibility of winning is not within the drawing range from the winning line, The left reel R1 and the right reel R3 are stopped so as not to win a prize.
The same applies to the case where the gray bell symbol stops at the middle display position M2 in the first stop operation as shown in FIG.

<B5-3: Relationship between stop operation and winning probability>
Next, the relationship between the stop operation and the winning probability will be described with reference to FIG. First, when the order of the pre-determined operation and the order of the actual stop operation are the same, the alternative symbol constituting the correct combination is drawn in the first stop operation, and 100% is arranged in the second stop operation and the third stop operation. The design will be drawn. For this reason, if the pre-decision operation order matches the actual stop operation order, the correct answer combination is awarded 100%.
Next, the first stop operation was the left reel R1 and the second stop operation was the right reel R3, the first stop operation was in agreement with the predetermined operation sequence, and the second stop operation was inconsistent with the predetermined operation sequence. Assume a case. In this case, in the second stop operation, the white map symbol of the selected combination is drawn in preference to the 100% arrangement symbol of the correct combination, so the white map symbol stops at the middle display position M3 with a probability of 50%, and 50% The 100% arrangement symbol with a probability stops at the middle display position M3. Then, when the 100% arrangement symbol is drawn into the winning line L5, the winning combination having the possibility of winning is limited to the correct winning combination. In this case, the CPU 101 draws the 100% arrangement symbols constituting the correct combination in the third stop operation to the middle display position M2. That is, the probability of winning the correct combination when the second stop operation does not match the predetermined operation order is 50%.
On the other hand, when a white map symbol is drawn to the middle display position M3 in the second stop operation, for a player who cannot identify the result of the internal lottery as any one role group, there is a possibility that the player may win a prize visually. There is a small role A “white plum-white bell-white map” and a small role E “white plum-grey bell-white map”. For this reason, in the third stop operation, the probability of winning the small combination A or the small combination E is 25%. Therefore, when it matches with the predetermined stop operation sequence until the first stop operation, the probability of winning a small combination is 75%.
Furthermore, when the first stop operation is the middle reel R2 or the right reel R3 and the order of operation determined from the first stop operation is different from the pre-determined operation order, each wins a small role with a probability of 25%.

  Thus, when the first stop operation does not match, the winning probability is 25%, and when the first stop operation matches and the second stop operation does not match, the winning probability is 75%, and the first stop operation and When the second stop operation matches, the winning probability is 100%. That is, according to the slot machine of the first embodiment, it is possible to increase the winning probability as the degree of coincidence between the predetermined operation sequence and the actual stop operation sequence increases.

  Next, with reference to FIG. 27, the winning probability when the player fixes the pushing order will be described. As shown in the figure, there are six stop operation orders, but there are one case each of which corrects all stop operation orders and one case where the first stop operation is correct and the second stop operation is incorrect. And four cases are cases where there is an error from the first stop operation. The probability of winning when the stop operation order is fixed is calculated by a weighted average in each case, and becomes 45.8%.

<3. Modification>
The present invention is not limited to the above-described embodiments, and for example, the following modifications are possible.
(1) In the second embodiment described above, when the predetermined operation order matches the actual first stop operation and the second stop operation, a winning is made with a probability of 100%, and the predetermined operation order and the first stop operation are If they match and the second stop operation does not match, it is possible to win with a probability of 75%. The present invention is not limited to this. In the case of a certain pressing order, the pre-determined operation order matches the first stop operation, and even if the second stop operation does not match, the winning is made with a probability of 100%. Also good.
For example, as shown in FIG. 28, when the first stop operation in the predetermined operation sequence is the left reel R1, even when the predetermined operation sequence and the first stop operation match and the second stop operation does not match, You may win with 100% probability. In this case, when the first stop operation is correctly answered with the left reel R1, even if the second stop operation is mistaken, stop control is performed so that the 100% arrangement symbol of the correct combination is drawn into the winning line from the symbol of the selected combination. Just do it.
However, in push order 1 (left → middle → right) and push order 2 (left → right → middle), the average probability of winning is 50%, and the average probability of winning in other push orders is 45.8%. It becomes high compared. For this reason, it is conceivable that the player performs a stop operation by fixing the pushing order 1 or the pushing order 2 in order to play the game under advantageous conditions. That is, there will be an advantage / disadvantage due to the pushing order.
Therefore, it is preferable to weight the lottery probability of the internal lottery based on the average probability of winning. Specifically, when the pushing order 1 and the pushing order 2 are “1”, the lottery values may be weighted so that the pushing orders 3 to 6 become “1.09”. In this case, the relationship between the role group and the lottery value is as shown in FIG. 29. For the role groups C1 to C4, D1 to D4, E1 to E4, and F1 to F4, The lottery value may be increased from 600 to 654 as compared with ~ i4.

Also, as shown in FIG. 30, when the first stop operation in the predetermined operation order is the left reel R1 or the middle reel R2, the predetermined operation order and the first stop operation match and the second stop operation does not match. In the case of, you may win with 100% probability. In this case, if the first stop operation is correct on the left reel R1 or the middle reel R2, even if the second stop operation is incorrect, the 100% arrangement symbol of the correct combination is drawn into the winning line from the symbol of the selected combination. It is sufficient to execute stop control.
Also in this case, it is preferable to weight the lottery probability of the internal lottery based on the average probability of winning so that the advantage / disadvantage due to the pressing order does not occur. Specifically, when the pushing order 1 to the pushing order 4 is “1”, the lottery values may be weighted so that the pushing orders 5 and 6 become “1.09”. In this case, the relationship between the role groups and the lottery values is as shown in FIG. 31. For the role groups Ho1 to Ho4 and F1 to He4, as compared with the role groups I1 to I4 and C1 to Ha4. The lottery value may be increased from 700 to 763.

(2) In the first and second embodiments described above, there are two types of symbols for the selection combination in each of the reels R1 to R3. However, the present invention is not limited to this, and there are three or more types. You may comprise an alternative design with a design.
As shown in FIG. 32, in the second embodiment, the small combination A to the small combination H are adopted as the selection combination. Since these are composed of two types of alternative symbols for each reel, the selected combination is composed of eight small combinations. On the other hand, when adopting three types of alternative symbols such as “circle”, “triangle”, and “cross” for each reel, 27 small roles 51 to 77 may be employed as the selected combinations. In this case, the symbols “circle”, “triangle”, and “cross” may be arranged on each reel so that the pull-in ranges do not overlap.
FIG. 33 shows the relationship between the stop operation order and the winning probability. In this case, since the number of alternative symbols constituting the selection combination in each reel is increased from two to three, the probability of predicting the alternative symbol and drawing it into the winning line is reduced from 1/2 to 1/3. . For this reason, when the pre-determined operation order matches the first stop operation and the second stop operation does not match, the probability of winning the winning combination decreases from 1/4 to 1/6. Furthermore, when the predetermined operation order and the first stop operation and the second stop operation are inconsistent, the probability of winning the winning combination is reduced from 1/4 to 1/9. As a result, the winning probability when the pushing order is fixed becomes 35.2%, and the winning probability can be lowered.
With reference to FIG. 34, the win probability which generalizes the number of alternative symbols of each reel will be described. The number of alternative symbols constituting the selective combination for the left reel R1 is L, the number of alternative symbols constituting the selective combination for the middle reel R2 is M, and the number of alternative symbols constituting the selective combination for the right reel R3 is R. And For example, when the pre-determined operation order is push order 1 (left → middle → right) and the actual push order is push order 2 (left → right → middle), the probability P of winning is P = ( 1 + 1 / M) / 2. Further, the winning probability when the pressing order is fixed is as shown in the figure.
Further, when there are some reels in which the correct answer in the pushing order is determined only by the first stop operation, only some reel calculation formulas are replaced with the formula shown in FIG. It ’s fine. A combination of [1] and [2] when some reels are the left reel R1, a combination of [3] and [4] when some reels are the middle reel R2, and some reels are the right reel R3 In the case of, each may be replaced with a combination of [5] and [6].

(3) In the embodiment and the modification described above, when a predetermined condition is satisfied, a part or all of the predetermined operation order may be notified. For the notification, the liquid crystal display device 30 or the like may be used. By notifying the player, the player can know the correct order of pushing, so that a winning can be surely obtained. For example, the predetermined condition may be that the notification is started when predetermined start points are aligned or when the BB game ends. When the notification is executed, the CPU 101 transmits information specifying the winning group won in the internal lottery from the main board 100A to the sub board 100B. In the ROM 194 (storage means) of the sub-board 100B, a role group and a predetermined operation order are stored in association with each other, and the CPU 191 reads out a predetermined operation order corresponding to the role group from the ROM 194, and based on this. Notification.
