Description

  The present invention relates to a gaming machine represented by a slot machine (pachislot) and a pachinko machine.

  Conventionally, for example, a slot machine is known as one of game machines. In this slot machine, when the reel is rotated by inserting a medal and operating the start lever, the role is determined internally by internal lottery, and the reel is stopped by operating the stop button. When a combination of symbols predetermined according to the internal determination is displayed, a combination is established. When a winning combination with payout of medals is established, a prescribed number of medals corresponding to the established winning combination are paid out.

  In such a gaming machine, when the same symbol combination is established on a predetermined line on the symbol display window, there are slot machines having different expectations for the bonus depending on the established predetermined line. For example, Patent Document 1 includes a weak watermelon in which a combination of watermelon symbols is displayed on the upper horizontal line and the lower right line, and a strong watermelon in which a combination of watermelon symbols is displayed on the middle horizontal line and the lower right line. A slot machine that can recognize a strong watermelon when a combination of watermelon symbols is displayed on a horizontal line is disclosed.

  “Special Roles 1 and 2” (hereinafter sometimes simply referred to as “BB (Big Bonus)”) is a special role in which a BB game, which is one of the special game states (also referred to as RT2), is started upon winning. (Operating role). The corresponding symbol combinations are “Seven 1 Symbol—Seven 1 Symbol—Seven 1 Symbol” for Special Role 1 (BB1) and “Seven 2 Symbol—Seven 2 Symbol—Seven 2 Symbol” for BB2. Further, flag carryover is performed for BB1 and BB2. In other words, when BB1 or BB2 is won internally, a flag indicating this is set (stored in a predetermined area of the RAM 308 of the main control unit 300), but even if BB1 or BB2 is not won in the game, a prize is won. The state where the flag indicating the internal winning is maintained until the next game is held, and the BB1 or BB2 is still in the internal winning (also referred to as RT1) after the next game, and the symbol combinations corresponding to the special winning combination in the internal winning are all won. It is in.

  “Special role 3” (hereinafter, sometimes simply referred to as “RB (regular bonus)”) is a special role (actuation) in which an RB game, which is one of the special game states (also referred to as RT2), is started upon winning. Role). The corresponding symbol combination is “Seven 1 symbol-Seven 1 symbol-BAR symbol”. Note that the RB carries over the flag as well as the above-mentioned BB. However, in the BB game, the regular bonus game is started after the start of the big bonus game without the start condition that the RB game is won internally or the symbol combination is displayed on the winning line. When the regular bonus game is completed, the regular bonus game may be automatically started so that the next regular bonus game is started immediately.

  “Re-playing combination (replay)” is a winning combination (operating combination) in which a game can be performed without inserting a medal (game medium) in the next game by winning, and no medal is paid out. In addition, as for the corresponding symbol combination, the replay is “replay symbol-replay symbol-replay symbol”.

  “Small 1 to 4” (hereinafter, “Small” 1 may be referred to as “Bell”, Small 2 as “Watermelon”, Small 3 as “Cherry”, and Small 4 as “Single”) Is a winning combination in which a predetermined number of medals are paid out by winning. Corresponding symbol combinations are “bell design-bell design-bell design” for small role 1 (bell), “watermelon design-watermelon design-watermelon design” for small role 2 (watermelon), “Cherry design-ANY design-ANY design”, and the small role 4 (single game) is “Seven 1 design-Blank 1 design-Cherry design”. Further, the corresponding payout numbers are as shown in the figure, with 10 small roles 1 (bell), 12 small roles 2 (watermelon), 2 small roles 3 (cherry), and 4 small roles (1) 1). In the case of “cherry symbol-ANY symbol-ANY symbol”, the symbol of the left reel 110 may be a “cherry” symbol, and the symbol of the middle reel 111 and the right reel 112 may be any symbol.

<Internal lottery value for winning roles>
Next, the lottery value of the winning combination will be described with reference to FIG. This figure shows an example of the name of the condition device (winning combination) and the internal winning probability for each RT mode.

  There are three gaming states of the slot machine 100: a normal gaming state (RT0), a special role internal winning state (RT1), and a special gaming state (RT2), and each winning game state (by RT mode) The internal winning probability is determined in advance. Hereinafter, the gaming state may be simply referred to as RT0 to RT2. The special winning internal winning state (RT1) is provided with an internal winning probability corresponding to the special winning combination.

  Here, to outline the gaming state, the contents of RT0 are not particularly limited. For example, the total number of medals that can be obtained during a game when the result of the internal lottery is largely lost and the player has played a game for a predetermined period. However, the game state is less than the total number of medals inserted during the game. RT0 is started when RT2 ends in addition to the initial state. In RT0, if any of the special roles 1 to 3 is won internally, the process proceeds to RT1.

  RT2 refers to a gaming state in which a symbol combination corresponding to the special combination won internally can be displayed on the active line. RT2 starts when a special combination 1 to 3 is specially won in RT0, and ends when the symbol combination corresponding to the special combination won internally is displayed on the active line, and proceeds to RT2. .

  RT2 is a gaming state having the greatest profit for the player, and refers to a gaming state in which the total number of medals acquired during the game exceeds the total number of medals inserted during the game. That is, as is apparent from the lottery values shown in FIG. 6, RT2 has a higher expected value of the number of game media to be paid out than RT0 and RT1. For this reason, RT2 can be said to be the most advantageous gaming state.

  RT2 is started when a symbol combination corresponding to the special combination won in RT1 is displayed on the active line, and a predetermined number of predetermined numbers during the game (in the case of this embodiment, in the case of BB1 and BB2) When medals exceeding 345 and 119 in the case of RB are paid out, the process is terminated, and the process proceeds to RT0.

  The internal winning probability of each winning combination is determined by a value obtained by dividing the lottery value associated with the condition device by the size of the numerical value range of the random value acquired at the time of the internal lottery (65535 in this embodiment). As an example, the internal winning probability of special combination 1 (NO1) at RT0 is 32/65536, and the internal winning probability of replaying combination (NO7) at RT0 is 8868/65536, re-establishment at RT1 during BB1 winning. The internal winning probability of the game combination (NO7) is 0/65536, and the internal winning probability of the small combination 1 (NO4) in RT2 is 57336/65536.

  These lottery values are associated in advance with one of the numerical ranges of the random number values (0 to 65535 in the present embodiment), and the main control unit 300 determines which random number value is obtained. The internal winning lottery process for determining the internal winning combination is performed by determining whether the lottery value corresponds to the winning combination. In addition, as the lottery value, setting 1 to setting 6 in which the internal winning probabilities of at least one winning combination are different are prepared, and an attendant of the game shop can arbitrarily select and set any setting value.

  In the present embodiment, in addition to a single combination that can be internally won for one type of winning combination, a multiple combination that can be internally won for a plurality of types of combinations is provided. For example, “small part 2 & small part 4” (No. 8 in FIG. 6) that wins special part 2 and small part 4 at the same time, and “special part 1 & small part” that wins special part 1 and small part 1 at the same time. “Combination 1” (NO 9 in FIG. 6), “Special Role 1, Small Role 2 & Small Role 4” (NO 10 in FIG. 6) and the like are won simultaneously for Special Role 1, Small Role 2 and Small Role 4. Note that a duplicate role does not mean that the condition device (flag) corresponding to the duplicate role is activated, but a plurality of roles included in the duplicate role (in the case of a duplicate role, multiple small roles included in the duplicate role) Each of the condition devices corresponding to) operates. For example, when “Special Role 1 & Small Role 1” is won internally, the winning flags for Special Role 1 and Small Role 1 are turned ON.

  In this embodiment, as shown in the remarks column of the figure, “small role 2” (NO5 in FIG. 6) is “weak watermelon”, “small role 2 & 4” (NO8 in FIG. 6) is “strong watermelon”, “Special role 1, small role 2 & small role 4” (NO10 in FIG. 6) is “BB1 double strong watermelon”, “Special role 1, small role 2” (NO11 in FIG. 6) is “BB1 double weak watermelon”, “ “Special role 2, small role 2 & small role 4” (NO16 in FIG. 6) is “BB2 double strong watermelon”, “Special role 2, small role 2” (NO17 in FIG. 6) is “BB2 double weak watermelon”, “Special “Combination 3, small combination 2 & small combination 4” (NO22 in FIG. 6) is referred to as “RB overlapping strong watermelon”, and “Special combination 3, small combination 2” (NO23 in FIG. 6) is referred to as “RB overlapping weak watermelon”. In the present embodiment, “strong watermelon”, “BB1 overlapping strong watermelon”, “BB2 overlapping strong watermelon” and “RB overlapping strong watermelon” are collectively referred to as “strong watermelon system”, “weak watermelon”, “BB1 overlapping weak watermelon”. "Watermelon", "BB2 overlapping weak watermelon" and "RB overlapping weak watermelon" are collectively referred to as "weak watermelon system".

  Here, the lottery value at RT0 of “strong watermelon system” is internally won for both the lottery value D1 and the bonus role (special roles 1 to 3) for internal winning of any of the bonus roles (special roles 1 to 3). If the lottery value D2 is not divided into two, D1 is 160 (= 40 + 40 + 80) and D2 is 160. Therefore, when the “strong watermelon system” is won internally, the expected value D1 / (D1 + D2) for the bonus winning is 1/2 ( = 160/320). On the other hand, the lottery value in RT0 of “weak watermelon system” is not internally won in any of the lottery value D3 and the bonus combination (special roles 1 to 3) for internal winning of any bonus combination (special combinations 1 to 3). If the lottery value D4 is divided into two, D3 is 160 (= 40 + 40 + 80) and D4 is 610. Therefore, when the “weak watermelon system” is won internally, the expected value D3 / (D3 + D4) for the bonus winning is about 1/4. 8 (= 160/770). In other words, in the present embodiment, the expected value for bonus provision when the “strong watermelon system” is internally won is set higher than the expected value for bonus provision when the “weak watermelon system” is internally won.

  Although “strong watermelon system” and “weak watermelon system” will be described in detail later, the display modes on the symbol display windows 113 of the reels 110 to 112 may be different. You may be able to know that you have won the “strong watermelon system” internally.

  Here, the display mode is a combination of symbols displayed in nine display areas, and in a narrow sense, means a symbol combination established on an effective line. If the effective line is different, the display mode is different even for the same symbol combination. In the present embodiment, four effective lines are set as shown in FIG. 2, but the setting of the effective lines is not limited to this, and any effective line such as a straight line or a bent line may be used. The effective line is composed of three display areas out of the nine display areas of the symbol display window 113, and any one display area is set for each of the reels 110 to 112. Is formed.

  Further, in this embodiment, as shown in the remarks column of the figure, “small role 3” (NO6 in FIG. 6) is changed to “horn cherry”, “special role 1, small role 3 & small role 4” (FIG. 6). No. 12) is “BB1 overlapping middle stage cherry”, “Special role 1, small role 3” (NO 13 in FIG. 6) is “BB1 overlapping corner cherry”, “Special role 2, small role 3 & small role 4” (in FIG. 6). NO18) is “BB2 overlapping middle stage cherry”, “special role 2, small role 3” (NO19 in FIG. 6) is “BB2 double angle cherry”, “special role 3, small role 3 & small role 4” (NO24 in FIG. 6). ) Is referred to as “RB overlapping middle cherry” and “special role 3, small role 3” (NO 25 in FIG. 6) is referred to as “RB overlapping angle cherry”. In the present embodiment, “BB1 overlapping middle cherry”, “BB2 overlapping middle cherry” and “RB overlapping middle cherry” are collectively referred to as “middle cherry system”, “horn cherry”, “BB1 overlapping corner cherry”, “BB2”. "Overlapping corner cherry" and "RB overlapping corner cherry" are collectively referred to as "corner cherry system".

  Here, the lottery value at RT0 of “middle stage cherry” is internally won for both the lottery value D5 and the bonus role (special roles 1 to 3) for internal winning of any bonus role (special roles 1 to 3). If the lottery value D6 is not divided into two, D5 is 4 (= 2 + 2) and D6 is 0. Therefore, when the internal winning is “middle stage cherry system”, the expected value D5 / (D5 + D6) for the bonus winning is 1 (= 4 / 4). On the other hand, the lottery data at RT0 of “Kaku cherry type” is not internally won for any of the lottery value D7 and the bonus combination (special combinations 1 to 3) for internal winning of any bonus combination (special combinations 1 to 3). If the lottery value D8 is divided into two, D7 is 0 and D8 is 1924. Therefore, when the “horn cherry system” is won internally, the expected value D7 / (D7 + D8) for the bonus winning is 0 (= 0/1924). . That is, in this embodiment, the expected value of bonus grant in the case of internal winning in the “middle cherry system” is set higher than the expected value of bonus grant in the case of internal winning in the “horn cherry system”. Specifically, the expected value of bonus grant when winning internally in the “middle cherry system” is 100%, that is, the bonus is definitely granted, whereas the expected value of bonus grant when winning internally in the “horn cherry system” is 0 %, That is, it is set so that a bonus is not surely given.

  Although “middle cherry system” and “corner cherry system” will be described in detail later, the display mode of the reels 110 to 112 on the symbol display window 113 may be different. You may be able to know that you have won the “Medium Cherry”.

  FIG. 7 shows a display mode on the symbol display window 113 of the reels 110 to 112 that are stopped when the “strong watermelon system”, “weak watermelon system”, “middle cherry system”, and “horn cherry system” are respectively elected internally. FIG. In FIG. 7, symbols other than the watermelon symbol and the cherry symbol are examples.

  In this embodiment, when the “strong watermelon system” is won internally, as shown in FIG. 7A, the combination of “watermelon symbol-watermelon symbol-watermelon symbol” is (a-1) the upper horizontal winning line L2. , (A-2) The reel control can be performed so as to stop display on the right-down winning line L3 or (a-3) the right-up winning line L4.

  On the other hand, when the “weak watermelon system” is won internally, as shown in FIG. 7B, the combination of “watermelon symbol-watermelon symbol-watermelon symbol” is (b-1) a right-down winning line L3, or ( b-2) The reel can be controlled so as to be stopped and displayed on the upward winning line L4.

  As described above, in the present embodiment, there is a common display mode between the display mode of “strong watermelon system” and the display mode of “weak watermelon system”, but there is a display mode that is only “strong watermelon system”. . Specifically, the display mode in which the combination of “watermelon design-watermelon design-watermelon design” shown in (a-1) is displayed in the upper horizontal winning line L2 exists only in the “strong watermelon system”. By visually recognizing the display mode, the player can grasp that the “strong watermelon system” having the high expected value of bonus grant has been won internally. In the following description, the display mode (a-1) existing only in the “strong watermelon system” is the display mode (a−) common to the “strong watermelon display mode”, “strong watermelon system”, and “weak watermelon system”. 2) and (a-3) (or (b-1) and (b-2)) are also referred to as “weak watermelon display mode”. Here, in the display mode when the strong watermelon system is won internally, there is a common display mode “display mode of weak watermelon” because the timing of the stop operation is not suitable, and “display mode of strong watermelon” This is because even if it is not possible to stop “,” the watermelon is won by avoiding the loss.

  Further, in this embodiment, when “middle stage cherry system” is won internally, as shown in FIG. 7C, the combination of “cherry pattern-ANY pattern-ANY pattern” is (c-1) middle stage horizontal prize. The reels can be controlled so as to stop and display on the line L1, (c-2) the lower right winning line L3 and the upper horizontal winning line L2, or (c-3) the upper right winning line L4.

  On the other hand, when “Square Cherry” is won internally, as shown in FIG. 7D, the combination of “Cherry Symbol-ANY Symbol-ANY Symbol” is (d-1) a down-right winning line L3 and an upper horizontal The reel can be controlled so as to be stopped and displayed on the winning line L2 or (d-2) the rising winning line L4.

  As described above, in the present embodiment, there is a common display mode between the display mode of “middle cherry type” and the display mode of “square cherry type”, but there is a display mode that is only “middle stage cherry type”. . Specifically, the display mode in which the combination of “cherry symbol-ANY symbol-ANY symbol” shown in (c-1) is displayed on the middle horizontal winning line L1 exists only in the “middle cherry line”. By visually recognizing the display mode, the player can grasp that the “medium stage cherry system” with a high expected value of bonus grant has been won internally. In the following, the display mode (c-1) existing only in the “middle cherry system” is the display mode (c−) common to the “middle cherry display mode”, “middle cherry system”, and “corner cherry system”. 2) and (c-3) (or (d-1) and (d-2)) are also referred to as “corner cherry display mode”. Here, there is a common display mode of “corner cherry display mode” in the case of internal winning for the middle cherry system, because the timing of the stop operation is not suitable, and the “middle cherry display mode” This is because even if it is not possible to stop the game, it is possible to avoid losing it and win the cherry.

<Reel stop control>
Next, an outline of the stop control of the reels 110 to 112 will be described. The reel stop control is performed based on the generated reel stop data based on a predetermined condition (for example, the result of the winning combination internal lottery process described above).

  In this embodiment, so-called pull-in control (frame slip control) is performed. With the pull-in control, the stop position of the reels 110 to 112 is shifted within a certain number of frames (number of symbols) (drawing range; here, a maximum of four frames) after each stop button 137 to 139 is operated by the player. Refers to control. The reel stop data is stored in the ROM 306 of the main control unit 300. Each reel stop data is allowed to allow a predetermined winning combination symbol combination to be displayed on the winning line 114 and to prohibit any winning combination symbol combination from being displayed on the winning line 114. And control.

  An example of the permissible control is, for example, when a winning combination is won internally, or when a special winning combination is being won internally (flag carryover), and when the player operates the stop buttons 137 to 139. Even if it is bad, control is performed so that the symbol combinations of winning combinations are displayed together within the range of the number of frames. However, since it is only “permitted”, there are cases where the symbol combinations are not aligned depending on the timing of operating each of the stop buttons 137 to 139.

  For example, when the small role 2 (watermelon) is won internally, the watermelon symbols are arranged in more than 4 frames, so if the timing of operating the stop buttons 137 to 139 is not suitable, the watermelon symbols will be the winning line 114. Never stop.

  However, 100% may be arranged depending on the arrangement of symbols on the reels 110 to 112 and the number of drawn frames. For example, since the replay symbol arrangement interval corresponding to the re-gamer (replay) is a maximum of 4 frames, if a re-gamer is won internally, 100% will be won regardless of the timing. In the present embodiment, since the arrangement interval of the symbols corresponding to the re-gamer (replay symbols) is a maximum of 4 frames in each of the reels 110 to 112, the re-gamer can always be drawn in when winning internally. It is a role.

  On the other hand, an example in which prohibition control is performed is, for example, a case where the internal lottery result is lost, and the internal winning of the special role is not being performed (flag carryover), and the timing at which the player operates the stop buttons 137 to 139 Even if it is good, control is performed so that the symbol combinations of winning combinations are not displayed together within the range of the number of frames.

<Reel stop data>
Next, an example of reel stop data generated in the present embodiment will be specifically described with reference to FIGS. 8 to 12 conceptually show reel stop data when the internal winning is made for the strong watermelon system or the weak watermelon system, and FIG. 13 conceptually shows the reel stop data when the internal winning is made for the middle stage cherry system or the square cherry system. It is. These reel stop data are data for specifically realizing the display mode shown in FIG.

  The reel stop data is data associating the symbol position of the reel, the stop position of the reel, and the pull-in (number of frames to be pulled in) when the reel is stopped, the internal lottery result of the winning combination, the stop order of the reels 110 to 112, It is dynamically generated according to the stop status. 8 to 13 show only reel stop data selected when some of the winning combinations are won internally. Actually, the reel stop data includes the winning combination, the game state, and the internal winning combination. A plurality of types are prepared according to the symbols stopped in the display areas 1 to 9.

  Of the symbol positions 0 to 20 of the reel stop data, the symbol positions marked with black circles in the reel stop position items are the display areas 2, 5, and 8 in the middle of the symbol display window 113 (the left reel 110 is the display area 2). The middle reel 111 indicates the position of the symbol to be stopped in the display area 5 and the right reel 112 in the display area 8). The symbol position with an upward arrow in the reel stop position item indicates the symbol position that is not stopped in the middle display areas 2, 5, and 8 of the symbol display window 113. The reel is rotated by the number of drawn frames described in the item (1), and the reel is stopped at the nearest symbol position where a black circle is marked in the reel stop position item (drawing control). Note that the symbol position of the reel indicated in the reel stop data indicates the symbol number located at the middle position (display areas 2, 5, 8) of the symbol display window 113 when the stop operation is performed. For example, in the left reel stop data 1 shown in FIG. 8A, when the bell symbol at the symbol position 4 is in the middle position of the symbol display window 113, the bell symbol at the symbol position 4 is 4 If the top symbol stops and the bell symbol at symbol position 0 stops in the display area 2 and the replay symbol at symbol position 5 is in the middle position of the symbol display window 113, the top symbol does not slip. The replay symbol at symbol position 5 stops in the display area 2.

  FIG. 8 is a diagram conceptually showing reel stop data of the left reel 110 when a strong watermelon system or a weak watermelon system is internally selected. FIG. 8A shows an internal winning system for a strong watermelon system or a weak watermelon system. (1) In the case of the first stop operation, (2) In the case of the second stop operation (when there is a possibility of winning a watermelon on the active line L2 or L3 as a result of the first stop operation), Or (3) Left reel stop data 1 in the case of the third stop operation (when there is a possibility of winning a watermelon on the active line L2 or L3 as a result of the first and second stop operations), FIG. When a strong watermelon system or a weak watermelon system is won internally, (1) in the case of the second stop operation (when the result of the first stop operation is a watermelon pattern on the effective line L4), or (2 ) In the case of the third stop operation (the result of the first and second stop operations) Shows the left reel stop data 2 when the symbol combination of watermelon is aligned) on the activated line L4.

  As shown in FIG. 8A, the left reel stop data 1 includes symbols corresponding to symbol positions 0, 5, 7, 12, and 16 in which black circles are marked in the reel stop position item. Data for stopping in the middle display area 2. That is, the left reel stop data 1 is the upper position of the symbol display window 113 when the stop operation is performed in the “upper position stop possible range” (symbol positions 7 to 11 and 16 to 20). Data to be stopped in the display area 1.

  In the present embodiment, when a stop operation is performed in the “L2 stop priority” range (symbol positions 7 to 10 and 16 to 19), the watermelon symbol is displayed in the display area 2 in the middle position of the symbol display window 113. However, the display area 1 at the upper stage is preferentially stopped.

  In addition, as shown in FIG. 8B, the left reel stop data 2 includes symbols corresponding to symbol positions 0, 5, 8, 12, 14, and 17 in which black circles are marked in the reel stop position item. This is data for stopping in the middle display area 2 of the symbol display window 113. That is, when the stop operation is performed in the “stoppable range” (symbol positions 5 to 9 and 14 to 18), the left reel stop data 2 is a display area where the watermelon symbol is the lower position of the symbol display window 113. 3 is data to be stopped.

  FIG. 9 is a diagram conceptually showing reel stop data of the middle reel 111 when the strong watermelon system is internally won. FIG. 9A shows the case where the strong watermelon system is internally won and (1 ) In the case of the first stop operation, (2) In the case of the second stop operation in accordance with the operation sequence of the left reel 110 as the first stop reel and the middle reel 111 as the second stop reel (the result of the first stop operation is an effective line) (3) When the first stop reel is the second stop operation according to the operation sequence of the right reel 112 and the second stop reel is the middle reel 111 (the first stop operation is possible) As a result of the stop operation, there is a possibility of winning a watermelon on the effective line L2 or L4), or (4) In the case of the third stop operation (result of the first and second stop operations, a watermelon win is obtained on the effective line L2) Middle reel stop) FIG. 9 (b) shows a case where a strong watermelon system is won internally, and (1) the first stop reel is in accordance with the operation order of the left reel 110 and the second stop reel is in the middle reel 111. In the case of two stop operations (when there is a possibility of winning a watermelon on the effective line L4 as a result of the first stop operation), (2) the first stop reel is operated on the right reel 112, and the second stop reel is operated on the middle reel 111. In the case of the second stop operation according to the order (if there is a possibility of winning a watermelon on the active line L3 as a result of the first stop operation), or (3) in the case of the third stop operation (first and second stops) As a result of the operation, middle reel stop data 2 is shown (when there is a possibility of winning a watermelon on the effective line L3 or the effective line L4).

  As shown in FIG. 9A, the middle reel stop data 1 includes symbols corresponding to symbol positions 1, 2, 7, 10, 14, 18, 19 in which black circles are marked in the reel stop position item. This is data for stopping the display area 5 in the middle of the symbol display window 113. That is, when the stop operation is performed in the “upper position stop possible range” (symbol positions 0, 2 to 6, 19 to 20), the middle reel stop data 2 indicates the watermelon symbol as the upper position of the symbol display window 113. This is data to be stopped in the display area 4.

  In the present embodiment, when the stop operation is performed in the “L2 stop priority” range (symbol positions 0, 2 to 5, 19 to 20), the watermelon symbol is displayed in the middle display position of the symbol display window 113. 5 can also be stopped, but the display area 4 at the upper stage is preferentially stopped.

  Further, as shown in FIG. 9B, the intermediate reel stop data 2 is a symbol display corresponding to the symbol positions 1, 5, 10, 14, and 18 in which black circles are marked in the reel stop position item. This is data for stopping the display area 5 in the middle of the window 113. That is, the middle reel stop data 2 indicates the middle position of the watermelon symbol in the symbol display window 113 when the stop operation is performed in the “middle position stop possible range” (symbol positions 0 to 5, 18 to 20). Data to be stopped in the display area 5.

  FIG. 10 is a diagram conceptually showing reel stop data of the middle reel 111 when the internal winning is performed for the weak watermelon system, and more specifically, when the internal winning is performed for the weak watermelon system, and (1) the first stop In the case of the operation, (2) in the case of the second stop operation in accordance with the operation sequence of the left reel 110 as the first stop reel and the middle reel 111 as the second stop reel (as a result of the first stop operation, the effective lines L2, L3 or (3) When the first stop reel is the second stop operation according to the operation sequence of the right reel 112 and the second stop reel is the middle reel 111 (first stop operation) As a result, there is a possibility of winning a watermelon on the effective line L2, L3 or L4), or (4) in the case of the third stop operation (the result of the first and second stop operations, on the effective line L3 or L4) There is a possibility of winning a watermelon It shows the reel stop data 3 in the case).

  The middle reel stop data 3 is the same as the middle reel stop data 2, and symbols corresponding to symbol positions 1, 5, 10, 14, and 18 with black circles in the reel stop position item are displayed as symbols. This is data for stopping the display area 5 in the middle of the window 113. That is, the middle reel stop data 2 indicates the middle position of the watermelon symbol in the symbol display window 113 when the stop operation is performed in the “middle position stop possible range” (symbol positions 0 to 5, 18 to 20). Data to be stopped in the display area 5.

  FIG. 11 is a diagram conceptually showing reel stop data of the right reel 112 when a strong watermelon system is internally won. FIG. 11A shows a case where a strong watermelon system is internally won and (1 ) In the case of the first stop operation, (2) In the case of the second stop operation in accordance with the operation sequence of the left reel 110 as the first stop reel and the right reel 112 as the second stop reel (the result of the first stop operation is an effective line) When there is a possibility of winning a watermelon on L2 or L3), or (3) In the case of the third stop operation (the result of the first and second stop operations, there is a possibility of winning a watermelon on the effective line L2 or L4) Case 1) right reel stop data 1, FIG. 11 (b) shows a case where a strong watermelon system is won internally. (1) Operation of the first stop reel as the middle reel 111 and the second stop reel as the right reel 112 In the case of the second stop operation according to the sequence (No. As a result of the stop operation, there is a possibility of winning a watermelon on the effective line L3), or (3) In the case of the third stop operation (result of the first and second stop operations, a watermelon winning is possible on the effective line L3 The right reel stop data 2 is shown.

  As shown in FIG. 11A, the right reel stop data 1 includes symbols corresponding to symbol positions 2, 7, 8, 10, 15, 16, and 18 in which black circles are marked in the reel stop position item. This is data for stopping in the middle display area 8 of the symbol display window 113. That is, when the stop operation is performed in the “upper position stop possible range” (symbol positions 0 to 6, 10 to 14, 18 to 20), the right reel stop data 1 indicates the watermelon symbol on the symbol display window 113. This is data to be stopped in the display area 7 which is the upper position.

  In the present embodiment, when the stop operation is performed in the “L2 stop priority” range (symbol positions 0 to 5, 10 to 13 and 18 to 20), the watermelon symbol is displayed at the middle position of the symbol display window 113. Although it is possible to stop the display area 8 as well, the display area 7 at the upper stage is preferentially stopped.

Case), or (2) right reel stop data 3 in the case of the third stop operation (if there is a possibility of winning a watermelon on the active line L4 as a result of the first and second stop operations), FIG. 12 (b) Is a case where a weak watermelon system is won internally, and (1) in the case of the first stop operation, (2) the first stop reel follows the operation order of the left reel 110, and the second stop reel follows the operation order of the right reel 112. In the case of the second stop operation (as a result of the first stop operation, (When there is a possibility of winning a watermelon on the line L3), (3) In the case of the second stop operation in accordance with the operation sequence of the middle reel 111 as the first stop reel and the right reel 112 as the second stop reel (first stop) As a result of the operation, there is a possibility of winning a watermelon on the effective line L3) or (4) In the case of the third stop operation (as a result of the first and second stop operations, there is a possibility of winning a watermelon on the effective line L3) The right reel stop data 4 is shown.

  As shown in FIG. 12A, the right reel stop data 3 includes symbols corresponding to symbol positions 2, 7, 8, 10, 15, 16, and 18 in which black circles are marked in the reel stop position item. This is data for stopping in the middle display area 8 of the symbol display window 113. That is, when the stop operation is performed in the “stoppable range” (symbol positions 0 to 6, 10 to 14, 18 to 20), the right reel stop data 3 indicates the watermelon symbol at the upper position of the symbol display window 113. This is data to be stopped in the display area 7.

  In the present embodiment, when the stop operation is performed in the “L2 stop priority” range (symbol positions 0 to 5, 10 to 13 and 18 to 20), the watermelon symbol is displayed at the middle position of the symbol display window 113. Although it is possible to stop the display area 8 as well, the display area 7 at the upper stage is preferentially stopped.

  Further, as shown in FIG. 12B, the right reel stop data 4 is a symbol display corresponding to symbol positions 0, 5, 8, 13, and 16 in which black circles are marked in the reel stop position item. This is data for stopping the display area 8 in the middle of the window 113. That is, when the stop operation is performed in the “lower position stop possible range” (symbol positions 0 to 4, 8 to 12, 15 to 20), the right reel stop data 2 indicates the watermelon symbol on the symbol display window 113. This is data to be stopped in the display area 9 which is the lower position.

  In the present embodiment, the right reel stop data 3 is the same data as the right reel stop data 1, and the right reel stop data 4 is the same data as the right reel stop data 2.

  As described above, as shown in the reel stop data of FIGS. 8 to 12, in this embodiment, when the strong watermelon system or the weak watermelon system is internally won, the watermelon is won according to the timing of the stop operation, In addition to displaying a strong watermelon display mode or a weak watermelon display mode, there may be cases where the watermelon is not won and the watermelon non-winning display mode is displayed. In other words, in the present embodiment, whether the display mode in the symbol display window 113 is a watermelon winning display mode (a strong watermelon display mode, a weak watermelon display mode), or a watermelon non-winning display mode, the watermelon is won internally. The possibility exists. Further, when the display mode in the symbol display window 113 is a watermelon winning display mode (a strong watermelon display mode, a weak watermelon display mode), the player can grasp that he has won a watermelon. it can. Furthermore, when the display mode in the symbol display window 113 is a strong watermelon display mode, the player can grasp that “strong watermelon system” has been won internally.

  FIG. 13 is a diagram conceptually showing reel stop data of the left reel 110 in the case of internal winning in the middle cherry system or the square cherry system, and FIG. 13 (a) is a case in which internal winning is performed in the middle cherry system. (1) In the case of the first stop operation, (2) In the case of the second stop operation (when the result of the first stop operation is that there is a possibility of winning a cherry on any of the effective lines L1 to L4), or ( 2) Left reel stop data 5 in the case of the third stop operation (when there is a possibility of winning a cherry on any of the effective lines L1 to L4 as a result of the first and second stop operations), FIG. In the case of internal winning in the corner cherry system, (1) in the case of the first stop operation, (2) in the case of the second stop operation (the result of the first stop operation is the cherry on any of the effective lines L1 to L4) If there is a possibility of winning) or (2 The third case of stop operation (first and second stop operation result, when there is a possibility of Cherry prize in any effective lines L1 to L4) indicates the left reel stop data 6.

  The left reel stop data 5 corresponds to the symbol positions 3, 7, 9, 10, 11, 16, 18, 19, 20 with black circles in the reel stop position items, as shown in FIG. This is data for stopping the symbol to be displayed in the middle display area 2 of the symbol display window 113. That is, the left reel stop data 5 can stop the cherry symbol at the upper, middle or lower position of the symbol display window 113 according to the timing of the stop operation. (Indicated as “middle stage”) ”(symbol positions 0 to 2, 10 to 14, 19 to 20), when the stop operation is performed, the watermelon symbol is displayed in the display area 2 that is the middle position of the symbol display window 113. When the stop operation is performed within the “lower position stop possible range (shown as“ lower stage ”)” (design positions 9 and 18), the watermelon symbol is displayed in the display area 3 which is the lower position of the symbol display window 113. When the stop operation is performed in the “upper position stop possible range (shown as“ upper ””) (symbol position 15), the watermelon symbol is displayed in the display area 1 that is the upper position of the symbol display window 113. Data to be stopped.

  In the present embodiment, when the stop operation is performed in the “L1 stop priority” range (symbol positions 0 to 1, 10 to 14, 19 to 20), the cherry symbol is displayed in the lower part of the symbol display window 113. Although the area 3 can be stopped, the display area 2 is preferentially stopped.

  Further, as shown in FIG. 13B, the left reel stop data 6 includes symbols corresponding to symbol positions 2, 7, 9, 11, 14, 18, and 20 in which black circles are marked in the reel stop position item. Is the data for stopping in the middle display area 2 of the symbol display window 113. That is, the left reel stop data 6 can stop the cherry symbol at the upper position or the lower position of the symbol display window 113 according to the timing of the stop operation. When the stop operation is performed at the symbol positions 3 and 14 to 15, the watermelon symbol is stopped in the display area 1 that is the upper position of the symbol display window 113, and the “lower position stop possible range” is displayed. (Indicated as “lower”) ”(symbol positions 0 to 1, 9 to 13, 18 to 20), when the stop operation is performed, the watermelon symbol is displayed in the display area 3 which is the lower position of the symbol display window 113. Data to be stopped.

  As described above, as shown in the reel stop data in FIG. 13, in this embodiment, when the middle-stage cherry system or the square cherry system is won internally, the cherry is won according to the timing of the stop operation, In addition to displaying the display mode or the display mode of the corner cherry, it may be missed and the cherry is not won, and the display mode of the cherry non-win is displayed. In other words, in the present embodiment, the cherry tree wins both in the display mode in the symbol display window 113, whether it is a cherry winning display mode (middle cherries display mode, corner cherry display mode) or cherry non-winning display mode. The possibility exists. In addition, when the display mode in the symbol display window 113 is a display mode of cherry winning (display mode of middle cherries, display mode of square cherries), the player can grasp that he has won a cherry. it can. Furthermore, when the display mode in the symbol display window 113 is the display mode of the middle cherries, the player can grasp that the “middle tier cherry system” is won internally.

<Display mode change effect>
Next, an outline of the display mode change effect will be described. The display mode change effect is (1) an effect that can be executed when the display mode for the weak watermelon is set as a result of the stop operation of the game that is won internally by the strong watermelon system, and the next game starts. Reel action that changes the display mode to rotate to the “strong watermelon display mode” by rotating the reels 110 to 112 stopped in the “display mode of weak watermelon” at the time of lever operation, (2) middle stage cherry system This is an effect that can be executed when the result of the stop operation of the game that was won internally is “display mode of corner cherry”, and stop at “display mode of corner cherry” when the start lever of the next game is operated The reel actions that rotate the reels 110 to 112 and change the display mode so as to become the “display mode of the middle cherries” are collectively referred to. Note that the rotation and stop of the reels 110 to 112 in the reel action is different from the rotation and stop of the reels 110 to 112 based on the normal start operation and stop operation, and the rotation and stop of the reels 110 to 112 as effects. It is not used for display determination.

  FIG. 14 shows an outline of the display mode change effect when the strong watermelon system is won internally in the previous game and the reels 110 to 112 are stopped in the display mode of the weak watermelon.

  FIG. 14A shows that in the second stop operation of the previous game, the operation timing of the stop button 138 with respect to the middle reel 111 was not suitable (because it was slow to push), so that the watermelon was won on the effective line L3. That is, the display mode of the weak watermelon is displayed. Specifically, for the middle reel 111, the stop control is performed using the above-described middle reel stop data 1 (see FIG. 9A), and the watermelon symbol at symbol position 1 or 18 is displayed on the display window 113. A stop mode when the stop button 138 is stopped when it passes through the display area 4 that is the upper position and does not reach the display area 5 that is the middle position is shown. As shown in FIG. 9A, the operation timing of the stop button 138 is a little earlier, specifically, the symbols in the “L2 stop priority” range (symbol positions 0, 2-5, 19-20) are in the middle position. If the stop operation can be performed at the time, the watermelon symbol is stopped in the display area 4 which is the upper position of the symbol display window 113, and a strong watermelon display mode is obtained.

  In the present embodiment, in such a case, when a predetermined condition is satisfied (specifically, as will be described later, by winning a lottery process for determining whether or not to execute a display mode change effect), FIG. 14 (b), based on the operation of the start lever 135 of the game this time, the reels 110 to 112 displayed in the weak watermelon display mode are operated to change to the strong watermelon display mode. Perform the production. Specifically, the middle reel 111 is rotated by one frame in the direction opposite to the normal rotation direction, and the right reel 112 is rotated by two frames in the direction opposite to the normal rotation direction so that the combinations of watermelon symbols are aligned on the effective line L2. To execute the reel action to be stopped. In addition, after finishing the display mode change effect, normal reel rotation is started with respect to the reels 110 to 112.

  Thus, in this embodiment, it is possible to show two display modes with respect to one stop operation. In other words, the display mode change effect is executed when the start lever operation of the next game after the stop operation is performed, and the display mode (strong watermelon) different from the display mode (the display mode of the weak watermelon) in the previous game where the stop operation was performed. Display mode), because the strong watermelon system in which the bonus is expected to be high in the previous game was won internally, and the timing of the stop operation is not suitable. It is possible to notify the player that the information has not been displayed. As a result, even if the display mode of the weak watermelon is displayed, the game can be continued without causing the player to end the game.

  In addition, although the display mode change effect shown in FIG. 14 was demonstrated using the example which changes the display mode shown in (a-2) of FIG. 7 to the display mode shown in (a-1), The same applies when the display mode shown in a-3) is changed to the display mode shown in (a-1). That is, in this case, the left reel 110 has two frames in the opposite direction to the normal rotation direction and the middle reel 111 has the opposite direction to the normal rotation direction so that the combinations of watermelon symbols are aligned on the effective line L2. What is necessary is just to perform the display mode change effect which rotates one frame and stops.

  FIG. 15 shows the outline of the display mode change effect when the internal winning of the middle stage cherries in the previous game is performed and the reels 110 to 112 are stopped in the display mode of the corner cherries.

  FIG. 15A shows that in the first stop operation of the previous game, the operation timing of the stop button 137 with respect to the left reel 111 was not suitable (because it was pressed quickly), so the cherry was won on the active lines L2 and L3. That is, the case where the display mode of the corner cherry is displayed is shown. Specifically, regarding the left reel 110, when the stop control is performed using the above-described left reel stop data 5 (see FIG. 13A), the watermelon symbol at the symbol position 15 is the upper position of the display window 113. The stop mode when the stop button 137 is stopped when it is in a position that passes through the display area 1 and does not reach the display area 2 that is the middle position is shown. As shown in FIG. 13A, the stop button 137 is operated a little later, specifically when the symbol in the “L1 stop priority” range (symbol positions 10 to 14) is in the middle position. If it is possible, the cherry symbol is stopped in the display area 2 which is the middle position of the symbol display window 113, and the middle cherry is displayed.

  In the present embodiment, in such a case, when a predetermined condition is satisfied (specifically, as will be described later, by winning a lottery process for determining whether or not to execute a display mode change effect), FIG. As shown in FIG. 15B, based on the operation of the start lever 135 this time, the reels 110 to 112 displayed in the corner cherry display mode are operated to change the display mode to the middle cherry display mode. Run. Specifically, a reel action is executed in which the left reel 111 is rotated by one frame in the normal rotation direction so that the cherry symbols of the left reel 110 are aligned on the effective line L1. Note that after the display mode changing effect is completed, normal reel rotation is started with respect to the reels 110 to 112.

  Thus, in this embodiment, it is possible to show two display modes with respect to one stop operation. That is, a display mode change effect is executed when the start lever of the next game after the stop operation is performed, and a display mode (middle cherry) different from the display mode (corner cherry display mode) in the previous game where the stop operation was performed. Display mode), so that the middle stage cherries with the high expected value of bonus grants in the previous game were won internally and the timing of the stop operation is not suitable, so the display mode of the middle cherries is displayed. The player can be notified of the failure. As a result, even if the corner cherry display mode is displayed, the game can be continued without causing the player to end the game.

  The display mode change effect shown in FIG. 15 has been described using an example in which the display mode shown in (c-2) of FIG. 7 is changed to the display mode shown in (c-1). The same applies when the display mode shown in c-3) is changed to the display mode shown in (c-1). That is, in this case, a display mode change effect is performed in which the left reel 110 is rotated by two frames in the direction opposite to the normal rotation direction so that the cherry symbols of the left reel 110 are aligned on the effective line L1. do it.

<Main control unit main processing>
Next, the main process of the main control unit 300 will be described with reference to FIG. FIG. 3 is a flowchart showing the flow of main processing of the main control unit 300.

  The main process of the main control unit is performed mainly by the CPU 304 of the main control unit 300, and the CPU 304 repeatedly executes the main process of the main control unit in FIG.

  When the power is turned on, first, various initial settings are made in step S101. In this initial setting, setting of a stack initial value to the stack pointer (SP) of the CPU 304, setting of interrupt prohibition, initial setting of the I / O 310, initial setting of various variables stored in the RAM 308, operation permission to the WDT 314, and initial setting Set the value.

  In step S102, medal insertion / start operation acceptance processing is executed. Here, it is checked whether or not a medal has been inserted, and the winning line display lamp 120 is turned on in response to the insertion of the medal. In addition, preparation is made for transmitting a medal insertion command indicating that a medal has been inserted to the first sub-control unit 400. Note that when a re-win is won in the previous game, a process of inserting the same number of medals as the number of medals inserted in the previous game is performed, so that it is not necessary for the player to insert medals. In addition, it is checked whether or not the start lever 135 has been operated, and if it is determined that the start operation has been performed, the number of inserted medals is determined, a valid pay line is determined, and the first sub-control unit 400 is confirmed. On the other hand, preparation is made to transmit a start lever reception command indicating that the start lever 135 has been operated.

  In step S103, a winning combination internal lottery process is executed. In the winning combination internal lottery process, the random number generated by the random number generation circuit 316 is acquired, the winning combination lottery table stored in the ROM 306 is read according to the current gaming state, and the acquired random number value is used. Internal lottery. As a result of the internal lottery, when any winning combination (including an operating combination) is won internally, the condition device (flag) of the internal winning combination is activated (the winning combination flag is turned ON). In step S103, preparation for transmitting an internal lottery command indicating the result of the winning combination internal lottery to the first sub-control unit 400 is made. For example, when the re-gamer (replay) is internally won, the internal lottery command indicating that the re-gamer (replay) is internally won is prepared for transmission to the first sub-control unit 400, and the winning combination When the result of the internal lottery is a loss (no winning combination), preparation is made to transmit an internal lottery command indicating a loss to the first sub-control unit 400.

  In step S104, a reel stop preparation process is executed. In the reel stop preparation process, reel stop data is generated based on the result of the winning combination internal lottery process in step S103.

  In step S105, a reel rotation start process (details will be described later) for starting the rotation of all the reels 110 to 112 is executed. Further, in this step S105, preparations are made for transmitting a spinning cylinder rotation start command indicating that the reels 110 to 112 have started to rotate to the first sub-control unit 400.

  In step S106, it is determined whether or not all the reels 110 to 112 are stopped. If all the reels 110 to 112 are stopped, the process proceeds to step S107, and if not, step S106 is repeated.

  In step S107, display determination processing (described later in detail) is performed. In the display determination process, when a symbol combination corresponding to some winning combination is displayed on the activated winning line 114, it is determined that the winning combination is won. For example, if “watermelon symbol-watermelon symbol-watermelon symbol” is aligned on the activated winning line, it is determined that the watermelon symbol is won. In step S107, preparation for transmitting a display determination command indicating the result of display determination to the first sub-control unit 400 is made.

  In step S108, a medal payout process is performed. In this medal payout process, if a winning combination with a payout is won, the number of medals corresponding to the winning combination is paid out.

  In step S109, a game state control process is performed in which control for shifting the game state is performed. For example, in the case of winning a BB (big bonus), preparation is made so that the BB gaming state (RT2) can be started from the next time. In step S109, preparation is made for transmitting a gaming state update command indicating the gaming state. For example, when the game state is BB game, preparation is made to transmit a game information update command indicating BB game.

  Thus, one game is completed. Thereafter, returning to step S102 and repeating the above-described processing, the game proceeds.

  The various commands prepared in the above steps are transmitted in a command setting transmission process (step S408 in FIG. 20) of the main control unit timer interrupt process described later.

<Reel rotation start processing>
Next, the reel rotation start process will be described in detail with reference to FIG. FIG. 17 is a flowchart showing in detail the flow of the reel rotation start process in step S105 of FIG.

  In step S201, a game time monitoring timer value is acquired. The game time monitoring timer is a timer stored in a specific storage area of the RAM 308 of the main control unit 300, and a time required for one game is a predetermined time (for example, 4.1 seconds of the minimum game time). This timer is set for the purpose of limiting the number of game media to be acquired or lost per unit time and limiting the gambling of the game. The game time monitoring timer is decremented each time a predetermined timer value (for example, a timer value corresponding to 4.1 seconds) is set in step S203, which will be described later, and timer interrupt processing (described later) of the main control unit 300 is executed. Is done.

  In step S202, it is determined whether or not the acquired gaming time monitoring timer value is 0, that is, whether or not 4.1 seconds or more have elapsed since the previous setting of the gaming time monitoring timer. If the acquired game time monitoring timer value is 0, 4.1 seconds or more have elapsed since the previous setting of the game time monitoring timer, and the current game may be started, so the process proceeds to step S203. On the other hand, if the acquired gaming time monitoring timer value is not 0, since 4.1 seconds or more have not elapsed since the previous setting of the gaming time monitoring timer, the process returns to step S201 and is repeated. While the processing is repeated, the timer value of the gaming time monitoring timer is decremented for each timer interrupt of the main control unit 300, and when the gaming time monitoring timer becomes 0, the process proceeds to step S203.

  In step S203, the game time monitoring timer value is reset. Specifically, a timer value corresponding to 4.1 seconds is stored in a specific area of the RAM 308. In the present embodiment, the time when the game time monitoring timer value is set is the start timing of one game. The end timing of one game is when the next game time monitoring timer value is set. That is, one game is from setting the game time monitoring timer value to setting the next game time monitoring timer value. Further, since the game time monitoring timer value is set every time the reels 110 to 112 start to rotate, the time from when the reels 110 to 112 start rotating until the next reel 110 to 112 starts rotating. It can also be a single game. Note that the end timing of one game may be when the game time monitoring timer value becomes 0 and the game state control process in S109 of FIG. 16 ends. In addition, the start timing of one game is set when the valid start lever is accepted, and the end timing of one game is set when the valid bet button operation can be accepted. The period up to the time of accepting may be a preparation period for the next game start.

  In step S204, it is determined whether or not the display mode change flag is ON. Here, the display mode change flag is flag information indicating whether or not to execute the display mode change effect, and is ON when it is determined to execute the display mode change effect in the display determination process (FIG. 19) described later. If it is determined not to execute the display mode change effect, it is set to OFF. When the display mode change flag is ON, the process proceeds to step S205, and when the display mode change flag is OFF, the process proceeds to step S207.

  In step S205, since the display mode change effect is executed at the start of reel rotation, the non-priority stop pattern NO set in the display determination process of the previous game (see FIG. 19) is acquired, and based on the acquired non-priority stop pattern NO. To set reel acceleration data. The non-priority stop pattern is when the strong watermelon system is won internally but the strong watermelon display mode is not displayed and the weak watermelon display mode is displayed, and when the middle cherry type is selected internally but the middle stage cherry display mode Is not displayed, and the display mode (stop pattern) when the display mode of the corner cherry is displayed is shown. Specifically, (a-2), (a-3), (c-) in FIG. The display mode of 2) and (c-3) is shown. That is, the non-priority stop pattern is a case where a predetermined combination having a plurality of display modes having different expected values for granting a bonus is internally won, and since the timing of the stop operation is not suitable, the expected value for granting a privilege is high. This means the second display mode in the case where the first display mode indicating that the second display mode indicating that the expected value for granting the privilege is low is displayed. In addition, in this embodiment, although both the 1st display mode and the 2nd display mode are comprised by the display mode which wins a predetermined combination, the 2nd display mode is a display mode which does not win a predetermined combination. It may be configured. In the present embodiment, each of the second display modes is managed in the display mode change table in association with a non-priority stop pattern NO that can be uniquely identified.

  Here, the display mode change table will be described with reference to FIG. FIG. 18 is a diagram schematically showing a display mode change table used in the present embodiment. The display mode change table is a data table for determining whether or not a non-priority stop pattern is applicable. In addition, according to each non-priority stop pattern NO, which reel should be moved in which direction and how much. It is the data table linked | related with the rotation data which shows.

  For example, the non-priority stop pattern NO1 corresponds to the display mode when winning a watermelon on the active line L3 (corresponding to (a-2) in FIG. 7). Specifically, the symbol (bell symbol) at symbol position 7 or 16 is displayed in the display area 2 of the symbol display window 113, and the symbol (watermelon symbol) at symbol position 1 or 18 is displayed in the display area 5 of the symbol display window 113. The display mode when the symbol (bell symbol) of symbol position 0, 8 or 16 is displayed in the display area 8 of the symbol display window 113 corresponds to the non-priority stop pattern NO1 and the non-priority stop pattern NO is 1. In this case, there is no movement of the left reel 110, the middle reel 111 is moved upward by one frame, that is, in the direction opposite to the normal rotation direction, and the right reel 112 is moved upward by two, ie, in the direction opposite to the normal rotation direction. Rotation data α that moves frame by frame is acquired. As a result, when the non-priority stop pattern NO1 is selected, first, rotation based on the rotation data α is performed to execute a display mode change effect, and then normal reel acceleration data (hereinafter referred to as reel acceleration data 1). Is used to accelerate the reels 110 to 112. That is, in step S205, rotation data for display mode change effects corresponding to the non-priority stop pattern NO and reel acceleration data 1 are set.

  The display mode change effect when the non-priority stop pattern NO1 is selected is the display mode change effect itself shown in FIG. On the other hand, the display mode change effect when the non-priority stop pattern NO2 is selected is not shown, but the display mode shown in (a-3) of FIG. 7 is the display shown in (a-1). This is a display mode change effect that changes to a mode.

  Further, for example, the non-priority stop pattern NO3 corresponds to the display mode when winning a cherry on the active lines L2 and L3 (corresponding to (c-2) in FIG. 7). Specifically, the display mode when the symbol 11 or 20 symbol (blank 1 symbol) is displayed in the display area 2 of the symbol display window 113 corresponds to the non-priority stop pattern NO3, and the non-priority stop pattern NO is 3. In this case, the left reel 110 is moved downward, that is, one frame in the normal rotation direction, and the rotation data β with no movement of the middle reel 111 and the right reel 112 is acquired. That is, when the non-priority stop pattern NO3 is selected, first, a display mode change effect is executed by performing rotation based on the rotation data β, and then the reels 110 to 112 are accelerated using the reel acceleration data 1. It is like that. The display mode change effect when the non-priority stop pattern NO3 is selected is the display mode change effect itself shown in FIG. On the other hand, the display mode change effect when the non-priority stop pattern NO4 is selected is not shown, but the display mode shown in (c-3) of FIG. 7 is the display shown in (c-1). This is a display mode change effect that changes to a mode.

  Returning to FIG. 17, in step S206, the display mode change flag is set to OFF.

  On the other hand, in step S207, since the display mode changing effect is not executed at the start of reel rotation, the reel acceleration data 1 is set.

  In step S208, the rotation control status is set to “accelerating”. The rotation control status is information stored independently for each reel 110-112 in a predetermined storage area of the RAM 308 of the main controller 300, and each reel 110-112 is in a stopped state. “Stopping”, which is information indicating that the reels are in an accelerated state, “Accelerating” which is information indicating that each of the reels 110 to 112 is in an accelerated state, and that each of the reels 110 to 112 is in a constant speed state. Information indicating that the reels 110 to 112 are in the retracted state, information indicating that the reels 110 to 112 are in the retracted state, and information indicating that the reels of the reels 110 to 112 are in the brake state. Any one of five pieces of information “braking” is stored.

  In step S209, a reel rotation start command to be transmitted to the first sub control unit 400 is set and preparation for transmission is made. The reel rotation start command is a command indicating the start of reel rotation.

<Display judgment processing>
Next, the display determination process will be described in detail with reference to FIG. FIG. 19 is a flowchart showing in detail the flow of the display determination process in step S107 of FIG.

  In step S301, display determination is performed to determine whether a symbol combination corresponding to a winning combination is displayed on the active line 114.

  In step S302, it is determined whether or not the winning combination that has won a prize is a target combination for a display mode change effect. Specifically, the target combination of the display mode change effect means a strong watermelon type or middle stage cherry type combination. If the winning combination that has won a prize is the target combination of the display mode change effect, the process proceeds to step S303, and if not, the process proceeds to step S308.

  In step S303, using the display mode change table (see FIG. 18) stored in the ROM 306, the display mode of the reels 110 to 112 on the symbol display window 113 corresponds to any display mode of the non-priority stop pattern. It is determined whether or not. If the display mode corresponds to any display mode of the non-priority stop pattern, the process proceeds to step S304, and if not, the process proceeds to step S308.

  In step S304, a lottery for determining whether or not to execute the display mode change effect is performed.

  In step S305, if the lottery in step S304 is won, the process proceeds to step S306. Otherwise, the process proceeds to step S308.

  In step S306, since the display mode change effect is executed, the display mode change effect flag is set to ON.

  In step S307, the corresponding non-priority stop pattern NO is stored in the RAM 308.

  In step S308, a preparation for transmitting a display determination command indicating the result of the display determination to the first sub-control unit 400 is made. Note that, when the display mode change effect is executed, information indicating that the display mode change effect is executed and information related to the non-priority stop pattern NO are also included in the display determination command.

<Main control unit timer interrupt processing>
Next, a main control unit timer interrupt process executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of the main control unit timer interrupt process.

  The main control unit 300 includes a counter timer 312 that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 1.5 ms), and the main control unit timer is triggered by this timer interrupt signal. Interrupt processing is executed at a predetermined cycle.

  In step S401, a timer interrupt start process is performed. In this timer interrupt start process, a process of temporarily saving each register value of the CPU 304 to the stack area is performed.

  In step S402, the WDT 314 is periodically updated (to prevent detection of processing abnormality) so that the WDT 314 count value exceeds the initial setting value (32.8 ms in the present embodiment) and no WDT interruption occurs. In the embodiment, the restart is performed once in about 1.5 ms which is the period of the main control unit timer interrupt.

  In step S403, input port state update processing is performed. In this input port status update process, the detection signals of the sensor circuits 320 of the various sensors 318 are input via the input ports of the I / O 310 to monitor the presence or absence of the detection signals, and each of the various sensors 318 is partitioned in the RAM 308. Store in the provided signal state storage area.

  In step S404, various game processes are performed. Specifically, an interrupt status is acquired (various interrupt statuses are acquired based on signals from various sensors 318), and processing according to this status is performed. For example, if the interrupt status is in the medal insertion process, the medal insertion acceptance process is performed. If the interrupt status is in the payout process, the medal payout process is performed.

  In step S405, timer update processing is performed. Various timers are updated for each time unit. For example, the game time monitoring timer value described above is updated.

  In step S406, device monitoring processing is performed. In this device monitoring process, first, the signal states of the various sensors 318 stored in the signal state storage area in step S403 are read, and the presence / absence of errors relating to medal insertion abnormality and medal payout abnormality is monitored, and when an error is detected. Performs error handling. Further, according to the current gaming state, the medal selector 170 (medal blocker in which the solenoid provided in the medal selector 170 operates), various lamps 338, and various 7-segment (SEG) indicators are set.

  In step S407, a reel control process (details will be described later) related to the rotation and stop of the reels 110 to 112 is executed.

  In step S408, command setting transmission processing is performed, and various commands are transmitted to the first sub-control unit 400. Note that the output schedule information transmitted to the first sub-control unit 400 is composed of 16 bits in the present embodiment, bit 15 is strobe information (indicating that data is set when ON), bit 11 -14 is a command type (in this embodiment, a basic command, a start lever reception command, an internal lottery command, a rotation rotation start command for starting the rotation of the reels 110 to 112, and an operation of the stop buttons 137 to 139 A stop button reception command, a reel stop command accompanying a stop process of the reels 110 to 112, a payout number command accompanying the medal payout process, a payout end command, etc.), bits 0 to 10 are command data (predetermined information corresponding to the command type) It consists of.

  The first sub-control unit 400 can determine the production control according to the change of the game control in the main control unit 300 by the command type included in the received output schedule information, and is included in the output schedule information. Based on the information of the command data, it is possible to determine the content of the effect control.

  In step S409, external signal output processing is performed. In this external signal output process, the game information stored in the RAM 308 is output to the information input circuit 652 that is separate from the slot machine 100 via the information output circuit 334.

  In step S410, it is monitored whether or not the low voltage signal is on. If the low voltage signal is on (when power supply shutoff is detected), the process proceeds to step S412. If the low voltage signal is off (power supply shutoff is not detected), the process proceeds to step S411.

  In step S411, various processes for ending the timer interrupt end process are performed. In this timer interrupt end process, the value of each register temporarily saved in step S301 is set in each original register. Thereafter, the process returns to the main process of the main control unit shown in FIG.

  On the other hand, in step S412, a specific variable or stack pointer for returning to the power-off state at the time of power recovery is saved as a return data in a predetermined area of the RAM 308, and power-off processing such as input / output port initialization is performed. Thereafter, the process returns to the main control unit main process shown in FIG.

<Reel control processing>
Next, the reel control process will be described in detail with reference to FIG. FIG. 21 is a flowchart showing in detail the flow of the reel control process in step S407 of FIG.

  In step S501, it is determined whether or not the operation of the stop buttons 137 to 139 is valid. Specifically, it is determined whether or not the operation of the stop buttons 137 to 139 is valid based on stop button validity information stored in a predetermined area of the RAM 308 and indicating whether or not the operation of the stop buttons 137 to 139 is valid. If the stop button valid information is set, it is determined that the operation of the stop buttons 137 to 139 is valid. The stop button valid information is set in a constant speed process described later (see FIG. 22). If the operation of the stop buttons 137 to 139 is valid, the process proceeds to step S502, a stop button reception process for receiving a stop operation of the stop buttons 137 to 139 is performed, and then steps S503 to S506 are performed for each reel 110 to 112. Perform the process. On the other hand, when the operation of the stop buttons 137 to 139 is not valid, the processes of steps S503 to S506 are performed for each of the reels 110 to 112.

  In step S503, index sensor processing is performed. In the index sensor process, index detection information indicating whether or not the reels 110 to 112 have reached a constant speed is acquired. The index detection information is information indicating whether or not the light shielding piece of the index sensor has been detected, and is stored in a predetermined area (index sensor storage area) of the RAM 308.

  In step S504, reel control information is acquired. Here, the reel control information means the entire information related to the rotation control of the reels 110 to 112, and is stored in a predetermined area of the RAM 308. In the present embodiment, values such as the above-described rotation control status, general-purpose offset counter, reel control status transition counter, and holding counter are included in the reel control information.

  In step S505, a reel rotation control process (described in detail later) is executed based on the acquired rotation control status.

  In step S506, since the content of the reel control information is changed according to the reel rotation control process described above, the reel control information is updated.

<Reel rotation control processing>
FIG. 22 is a flowchart showing in detail the flow of the reel rotation control process in step S505 of FIG. The reel control determination process is a process of sequentially switching the reel rotation control in accordance with the rotation control status. Specifically, processing is executed in the order of acceleration processing, constant speed processing, retraction processing, and brake processing.

  In step S601, the rotation control status is acquired.

  In step S602, it is determined whether or not the acquired rotation control status is “stopping”. When the rotation control status is “stopped”, the reel rotation control process is terminated, and when the rotation control status is not “stopped”, the process proceeds to S603.

  In step S603, it is determined whether or not the acquired rotation control status is “accelerating”. When the rotation control status is “accelerating”, the process proceeds to step S604, and an acceleration process that is a control process for accelerating the rotation of the reels 110 to 112 is executed, and when the rotation control status is not “accelerating”. The process proceeds to step S605.

  In step S605, it is determined whether or not the acquired rotation control status is “constant speed”. If the rotation control status is “constant speed”, the process proceeds to step S606, where constant speed processing, which is control processing for maintaining the rotation of the reels 110 to 112, is executed. If it is not “in-speed”, the process proceeds to step S607.

  In step S607, it is determined whether or not the acquired rotation control status is “braking”. If the rotation control status is “braking”, the process proceeds to step S608 to execute a brake process that is a control process for stopping the rotation of the reels 110 to 112. If the rotation control status is not “braking” The process proceeds to step S609.

  In step S609, since the rotation control status is “retracting”, a retraction process for performing retraction control of the reels 110 to 112 to the stop position is executed. In the pull-in process, pull-in control of the reel 110 is performed based on the reel stop data generated in the above-described reel stop preparation process (S104 in FIG. 16).

<Processing of First Sub-Control Unit 400>
The process of the first sub control unit 400 will be described with reference to FIG. FIG. 5A is a flowchart of main processing executed by the CPU 404 of the first sub control unit 400. FIG. 4B is a flowchart of command input processing of the first sub-control unit 400, and FIG. 4C is a flowchart of command reception interrupt processing of the first sub-control unit 400. FIG. These are the flowcharts of the timer interruption process of the 1st sub control part 400. FIG.

  When the power is turned on, first, initial setting is executed in step S701. In this initial setting, initial setting of the input / output port, initialization processing of the storage area in the RAM 408, and the like are performed.

  In step S702, it is determined whether or not the timer variable is 10 or more, and this process is repeated until the timer variable becomes 5. When the timer variable becomes 10 or more, the process proceeds to step S703.

  In step S703, 0 is assigned to the timer variable.

  In step S704, a first sub control unit command input process (details will be described later) is performed. In the first sub control unit command input process, it is determined whether or not a command has been received from the main control unit 300. When a command is received, a process corresponding to the received command is performed.

  In step S705, an effect control process is performed. For example, when there is a new command in step S704, the effect data is read from the ROM 406 based on the result of each event process (for example, effect setting process, gaming state control process, etc.) corresponding to this command. When the effect data needs to be updated, the effect data of each effect device (speaker, lamp, liquid crystal image display device, shutter, etc.) is updated.

  In step S706, sound control processing is performed. In the sound control process, if there is a command to the sound source IC 418 in the effect data read in step S705, this command is output to the sound source IC 418.

  In step S707, lamp control processing is performed. In the lamp control process, if there is a command to various lamps 420 in the effect data read in step S705, this command is output to the drive circuit 422.

  In step S708, information output processing is performed. In the information output process, when there is a control command to be transmitted to the second sub-control unit 500 in the effect data read in step S705, the control command is set to be output, and the process returns to step S702. As a result, the set control command is transmitted to the second sub-control unit 500.

  Next, the first sub control unit 400 command input process will be described with reference to FIG. The first sub control unit 400 command input process is a flowchart showing the flow of the first sub control unit 400 command input process of step S704 in FIG.

  In step S801, it is determined whether there is an unprocessed command in the command storage area of the RAM 408. If there is an unprocessed command, the process proceeds to step S802. If there is no unprocessed command, the first sub-control unit 400 command input process is terminated.

  In step S802, the process jumps to a process corresponding to an unprocessed command. For example, when the unprocessed command is a display determination command and the display determination command includes information indicating the execution of the display mode change effect, the effect corresponding to the non-priority stop pattern NO is determined to be displayed. Jump to the display mode change effect process executed at the time of operation and start lever operation. In the display mode change effect process, for example, at the time of display determination (when the display mode of weak watermelon or horn cherry is displayed), a word such as “chance ?!” is displayed on the effect image display device 157 and the privilege is displayed. A notification that expects the grant is made, and when the next start lever is operated (when a strong watermelon or middle cherry display is displayed by the reel action), characters such as “elevation” are displayed on the effect image display device 157 You may make it alert | report that it was made to win the role of privilege provision. When the display is determined, an effect such as “Press a little faster” is displayed on the effect image display device 157 to notify the timing of the stop operation, and when the next start lever is operated, the effect image display device 157 is displayed. In addition, it is possible to perform an effect of notifying that it is possible to stop, such as “There is a way to stop”, and notifying that the bonus is awarded internally.

  Next, the command reception interrupt process of the first sub-control unit 400 will be described with reference to FIG. This command reception interrupt process is a process executed when the first sub-control unit 400 detects a strobe signal output from the main control unit 300. In step S901 of the command reception interrupt process, the command output from the main control unit 300 is stored in the command storage area provided in the RAM 408 as an unprocessed command.

  Next, the first sub control unit timer interrupt process executed by the CPU 404 of the first sub control unit 400 will be described with reference to FIG. The first sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms). Execute in the cycle.

  In step S1001, 1 is added to the value of the timer variable storage area of the RAM 408 described in step S702 in the first sub-control unit main process shown in FIG. Therefore, in step S702, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

  In step S1002, various update processes such as an effect random number update process are performed.

<Processing of second sub-control unit>
The process of the second sub control unit 500 will be described with reference to FIG. FIG. 6A is a flowchart of main processing executed by the CPU 504 of the second sub-control unit 500. FIG. 7B is a flowchart of command reception interrupt processing of the second sub control unit 500. FIG. 8C is a flowchart of the timer interrupt process of the second sub control unit 500. FIG. 4D is a flowchart of the image control process of the second sub control unit 500.

  First, the main process of the second sub control unit 500 will be described with reference to FIG.

  When the power is turned on, an initialization process is first executed in S1101. In this initialization process, input / output port initialization, storage area initialization in the RAM 508, and the like are performed.

  In step S1102, it is determined whether or not the timer variable is 10 or more, and this process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or more, the process proceeds to step S1103.

  In step S1103, 0 is assigned to the timer variable.

  In step S1104, command processing is performed. The CPU 504 of the second sub control unit 500 determines whether a command has been received from the CPU 404 of the first sub control unit 400.

  In step S1105, an effect control process is performed. For example, if there is a new command in step S1104, processing such as reading effect data corresponding to the command from the ROM 506 is performed, and if the effect data needs to be updated, effect data update processing is performed.

  In step S1106, if there is a shutter control command in the effect data read in step S1105, shutter control corresponding to this command is performed.

  In step S1107, if there is an image control command in the effect data read in step S1105, image control corresponding to this command is performed (details will be described later), and the process returns to step S1102.

  Next, the command reception interrupt process of the second sub control unit 500 will be described with reference to FIG. This command reception interrupt process is a process executed when the second sub control unit 500 detects the strobe signal output from the first sub control unit 400.

  In step S1201 of the command reception interrupt process, the command output from the first sub-control unit 400 is stored as an unprocessed command in a command storage area provided in the RAM 508.

  Next, the second sub control unit timer interrupt process executed by the CPU 504 of the second sub control unit 500 will be described with reference to FIG. The second sub-control unit 500 includes a hardware timer that generates a timer interrupt at a predetermined cycle, and executes a timer interrupt process at a predetermined cycle triggered by this timer interrupt.

  In step S1301, 1 is added to the value of the timer variable storage area of the RAM 508 described in step S1102 in the second sub-control unit main process shown in FIG.

  In step S1302, various update processes for updating the production random number and the like are performed.

  Next, the image control processing of the second sub control unit 500 will be described with reference to FIG. FIG. 4D is a flowchart showing in detail the flow of image control processing in step S1107 in FIG.

  In step S1401, an instruction to transfer image data is issued. Here, the CPU 504 first swaps the designation of the display areas A and B in the VRAM 536. As a result, an image of one frame stored in the display area not designated as the drawing area is displayed on the effect image display device 157. Next, the CPU 504 sets ROM coordinates (transfer source address of the ROM 506), VRAM coordinates (transfer destination address of the VRAM 536), and the like in the attribute register of the VDP 534 based on the position information table and the like, and then the image from the ROM 506 to the VRAM 536. Set an instruction to start data transfer. The VDP 534 transfers the image data from the ROM 506 to the VRAM 536 based on the command set in the attribute register. Thereafter, the VDP 534 outputs a transfer end interrupt signal to the CPU 504.

  In step S1402, it is determined whether or not a transfer end interrupt signal from VDP 534 is input. If a transfer end interrupt signal is input, the process proceeds to step S1403. Otherwise, a transfer end interrupt signal is input. Wait for it.

  In step S1403, parameters are set based on the production scenario configuration table and attribute data. Here, in order to form a display image in the display area A or B of the VRAM 536 based on the image data transferred to the VRAM 536 in step S1401, the CPU 504 includes information on image data constituting the display image (coordinate axes and image sizes of the VRAM 536). , VRAM coordinates (arrangement coordinates, etc.) are instructed to the VDP 534. The VDP 534 performs parameter setting in accordance with the attribute based on the instruction stored in the attribute register.

  In step S1404, a drawing instruction is performed. In this drawing instruction, the CPU 504 instructs the VDP 534 to start drawing an image. The VDP 534 starts drawing an image in the frame buffer in accordance with an instruction from the CPU 504.

  In step S1405, it is determined whether or not the generation end interrupt signal from the VDP 534 based on the end of image drawing is input. If the generation end interrupt signal is input, the process proceeds to step S1406. If not, the generation end interrupt signal is determined. Wait for input.

  In step S1406, a scene display counter that is set in a predetermined area of the RAM 508 and counts how many scene images have been generated is incremented (+1), and the process ends.

<Others>
In the above embodiment, (1) when a strong watermelon system is won internally and a weak watermelon display mode is displayed, (2) an internal winning is displayed for the middle cherry system and a corner cherry display mode is displayed. In this case, the display mode change effect is executed, but the trigger for executing the display mode change effect is not limited to this. For example, the display mode change effect may be executed when a strong watermelon system is won and missed, that is, when a watermelon is not won.

  FIG. 25 is a diagram showing an outline of a display mode change effect that is executed when a strong watermelon system is won internally and a watermelon is not won.

  FIG. 25A shows a case where the operation timing of the stop button 138 with respect to the reel 111 in the previous game was not suitable, so that the watermelon was not won, that is, the display mode of the weak watermelon and the strong watermelon was not displayed. Show. In the example shown in FIG. 25A, watermelon symbols are displayed in the display areas 1 and 7.

  In this case, in this case, as shown in FIG. 25 (b), the display mode in which the reels 110 to 112 are operated to change to the strong watermelon display mode based on the operation of the start lever 135 of the current game. Execute the change effect. Specifically, a reel action is executed to stop the middle reel 111 by rotating it five frames in the direction opposite to the normal rotation direction so that the combinations of watermelon symbols are aligned on the effective line L2. In addition, after finishing the display mode change effect, normal reel rotation is started with respect to the reels 110 to 112.

  In this way, in this modified example, when a strong watermelon is elected internally, even if the stop operation is performed at a position where the watermelon symbol cannot be retracted and is lost, it will be displayed when the start lever is operated for the next game after the stop operation. Since it is possible to display a display mode (strong watermelon display mode) that is different from the display mode (display mode of missing) in the previous game in which the mode change effect was executed and the stop operation was performed, It is possible to notify the player that the strong watermelon system having a high expected value of giving has been internally won and that the timing of the stop operation is not suitable, so that the display mode of the strong watermelon has not been displayed. As a result, even if the display mode of the weak watermelon is displayed, the game can be continued without causing the player to end the game.

  In addition, in this modification, by registering in advance in the display mode change table a plurality of dropout display modes (combinations of symbols displayed in nine display areas on the symbol display window 113) as non-priority stop patterns. It is possible to determine whether or not the display mode of missing is displayed at the time of display determination. That is, the non-priority stop pattern includes not only the display mode when the predetermined combination is won internally and winning, but also the display mode when the predetermined combination is won internally and the predetermined combination cannot be won. May be.

  In the modification shown in FIG. 25, the reel action for operating one reel is performed to execute the display mode change effect, but the number of target reels of the display mode change effect is not limited to this. In the modification shown in FIG. 25, the number of moving frames of the target reel is 5, but the number of moving frames of the display mode change effect is not limited to this. That is, in this modified example, the reel action may be performed so as to fill the difference between the previous game display mode and the strong watermelon display mode, so the number of target reels and the number of moving frames are not particularly limited. For example, the number of target reels may be two or three, and the number of moving frames may be the number of symbols (1-2 frames) that move the symbol within the symbol display window 113, or the symbol outside the symbol display window 113. May be the number of frames (three or more frames) moved into the symbol display window 113.

  Further, in the above embodiment, the expected value of bonus grant when an internal winner is selected for `` strong watermelon system '' is set higher than the expected value of bonus grant when an internal winner is selected for `` weak watermelon system ''. The bonus grant expected value in the case of the internal winning “middle cherry system” is set higher than the expected bonus grant value in the case of the “horned cherry system” internal winning, and bonus granting is set. However, the privilege grant is not limited to the bonus grant. For example, privilege grants such as AT (assist time) grant, advantageous point grant, and an advantageous number of games in an advantageous state, triggered by internal winning of the role may be used.

  Moreover, in the said embodiment, although execution of the display mode change effect was started when the operation of the start lever 135 was received, the execution timing of the display mode change effect is not limited to this, and the reels 110 to 112 in the current game are not limited to this. Any timing may be used after the stop result is displayed and before the next game stop operation. For example, (1) a freeze period (a period during which a standby process is executed to delay the timing for accepting the next operation) is provided after the display determination process for the current game, and a display mode change effect is executed during this freeze period. Alternatively, (2) a freeze period may be provided at the time of accepting a bet operation for the next game, and a display mode change effect may be executed during the freeze period.

  In the above embodiment, when the display mode change effect is executed, for example, the display mode of the weak watermelon is changed to the display mode of the strong watermelon, or the display mode of the corner cherry is changed to the display mode of the middle cherry. The symbols of the corresponding reels 110 to 112 have been moved one or two frames in the reel rotation direction or in the direction opposite to the reel rotation direction, but after the corresponding reels 110 to 112 are rotated once (or several times), One frame or two frames may be moved in the above direction. Also, a reel with no symbol movement may be stopped at the same position after being rotated once (or several times).

  The relationship between the effective line provided on the symbol display window 113 and the display mode is not limited to that shown in FIG. For example, when a display mode opposite to that of the above embodiment is adopted and a weak watermelon system is won internally, the display mode of FIGS. 7 (a-1) to (a-3) can be displayed, while strong watermelon When the system is won internally, the display modes shown in FIGS. 7B-1 to 7B-2 may be displayed. In this case, when the display mode of FIG. 7 (a-2) or (a-3) is changed to the display mode of FIG. 7 (a-1) by executing the display mode change effect, a game The person can grasp that the “weak watermelon system” with the low expected value of bonus grant was won internally. Moreover, even if a display mode change effect is performed and a reel action is performed, the display mode of FIG. 7 (a-2) or (a-3) is not changed and FIG. 7 (a-2) or (a- When the display mode of 3) remains the same, the player can grasp that there is a high possibility that the “strong watermelon system” having a high expectation value for giving bonus is internally won.

  Further, for example, a display mode (referred to as display mode P1) in which a lower horizontal winning line constituted by the display areas 3, 6, and 9 is provided and watermelon symbols are aligned on the lower horizontal winning line is referred to as a weak watermelon display mode. , A display mode (referred to as display mode P2) in which watermelon symbols are aligned on the right-down winning line constituted by the display areas 1, 5, 9 or the right-up winning line constituted by the display areas 3, 5, 7 It is good also as a display mode of strong watermelon. The reverse, that is, the display mode P1 may be a strong watermelon display mode and the display mode P2 may be a weak watermelon display mode.

  In the above-described embodiment, as shown in FIG. 7, the strong watermelon and the weak watermelon display mode, and the middle cherries and the corner cherries display mode are all displayed on the straight line. Therefore, when the display mode change effect is executed, the display mode is changed from the display mode in which the corresponding symbol combination is aligned to the effective line on one straight line to the effective mode on the other straight line. However, apart from this, a bent winning line (for example, a winning line constituted by the display areas 1, 5, 7 and a winning line constituted by the display areas 1, 5, 8, etc.) is provided, and this bent prize line is provided. For example, the display mode when watermelon symbols are arranged on the line may be the display mode of strong watermelon or weak watermelon. In this case, when the display mode change effect is executed, the display mode in which the watermelon symbol combination is aligned with the effective line on one straight line is changed to the display mode aligned with the effective line on one flexion, The display mode aligned with the active line is changed to the display mode aligned with the active line on one straight line.

  In the above embodiment, when the display mode change effect is executed, the reel action rotation data (for example, the rotation data α and β described above) and the normal reel acceleration data 1 are set as the reel acceleration data (FIG. 17). (See step S205). That is, when executing the display mode change effect, the reel acceleration data is constituted by two rotation data. Separately, the reel acceleration data is converted into one rotation data, that is, rotation data taking into account the rotation of the reel action. It may be configured.

  Note that the slot machine may be a slot machine that only exchanges electronic data without using medals. In this case, the game medium includes computerized data corresponding to medals. The input includes inputting the digitized data from a predetermined external device (electronic storage device), and the payout of the game medium is the conversion of the digitized data to the predetermined external device (electronic storage device). Including output.

<Summary of Embodiment>
As described above, according to the gaming machine of the above embodiment (for example, slot machine 100, pachinko machine 1000), a plurality of reels (for example, reels 110 to 112) that are provided with a plurality of types of symbols and are rotationally driven. And a display area (for example, a symbol display window 113, a display region) that displays a plurality of symbols of the symbols provided on the reels along the rotation direction for each of the reels. 1-9) and lottery means (for example, main control unit 300, winning combination internal lottery process) for lottery of internal winning of a plurality of types of combinations including the first combination (for example, strong watermelon system, middle cherry system) S103) and stop operation accepting means (for example, stop buttons 137 to 139, main control unit 300, stop button) for accepting each stop operation for individually stopping the rotation of the plurality of reels. Based on the lottery result received by the lottery means and stop control means (for example, the main control unit 300, which performs stop control to stop the reel corresponding to the stop operation accepted by the stop operation accepting means) Reel stop preparation process S104, pull-in process S609), determination means for determining the symbol combination displayed in the display area (for example, main control unit 300, display determination process S107), and the determination result by the determination means , A gaming machine comprising a profit granting means (for example, main control unit 300, medal payout process S108, game state control process S109) for giving a profit to the player, wherein the stop control means is controlled by the lottery means. Based on the fact that the first combination is drawn, a predetermined display (for example, watermelon design, cherry design) is displayed in the first display mode. For example, one of a strong watermelon display mode, a middle cherry display mode) or a second display mode different from the first display mode (for example, a weak watermelon display mode, a corner cherry display mode). The reel effect control means (for example, the main control unit 300, the reel rotation start) that performs the reel effect control that performs the stop control that permits the display in the display area and changes the display mode displayed in the display area as the effect. And the reel effect control means displays the predetermined symbol in the first display mode by the stop control means based on the fact that the first combination is drawn by the lottery means. The basic configuration is to allow the change of the first display mode to the second display mode in the reel effect control when displayed in the area.

  According to this basic configuration, when the second display mode is displayed based on the reel stop operation, the first display mode is also displayed as an effect after the second display mode. A plurality of stop modes can be presented to the player by operation.

  In the above basic configuration, the plurality of types of combinations include a second combination different from the first combination (for example, a weak watermelon system, a horn cherry system), and an internal winning by the lottery means. The expected value for a predetermined privilege grant (for example, bonus grant, AT grant, advantageous point grant, advantageous game number grant, etc.) is set higher for the first role than for the second role, The stop control means performs stop control that allows the predetermined symbol to be displayed in the display area in the first display mode based on the fact that the second combination has been drawn by the lottery means. Is preferred.

  In this case, even if the first display mode is displayed, the player can be encouraged to play the game, and the game can be continued.

  Further, in the above configuration, the stop control unit stops the reel corresponding to the stop operation within a predetermined pull-in range (for example, within 4 frames) after receiving the stop operation by the stop operation receiving unit. Control, and in the pull-in stop control, when it is impossible to display the predetermined symbol in the display area in the second display mode, the predetermined symbol in the first display mode. It is desirable to perform stop control that allows display in the display area.

  In this case, since the second display mode cannot be displayed unless the timing of the stop operation is suitable, it is possible to determine whether or not the timing of the stop operation is suitable, that is, whether the eye is good or bad. It can be used to improve the skills of beginners.

  In the above configuration, the predetermined symbol in the second display mode is the same position as the predetermined symbol in the first display mode on the display area, or the first display mode. It is above the position of a predetermined symbol, and the reel effect control means changes the first display mode to the second display mode by rotating in a direction opposite to the rotation direction. It may be.

  In this case, since the reel is rotated in the direction opposite to the normal reel rotation, it is easy to recognize it as a reel effect, and it is not mistaken for a failure of the reel.
