The rim portion 93r of the reel frame 93 and the rim portion 94r of the reel frame 94 are formed in an annular shape along the left and right edges of the reel sheet 95, respectively.
The reel frame 93 includes a hub portion 93h that is detachably fixed to the rotor 54r of the stepping motor 54, and a plurality of spoke portions 93s that connect the rim portion 93r and the hub portion 93h in the radial direction. .

  In this example, the reel frame 94 is not directly connected to the reel frame 94, and the rim portion 94 r of the reel frame 94 is connected to the rim portion 93 r of the reel frame 93 via the reel sheet 95. (Of course, the rim portion 94r and the rim portion 93r can be integrally connected, for example, at one or a plurality of locations in the circumferential direction).

The reel sheet 95 is formed in a belt shape having a constant width by using, for example, a colorless and transparent synthetic resin sheet, is wound around the rim portions 93r and 94r of the reel frames 93 and 94, and is adhered by, for example, an adhesive. Although not shown in the drawing, a plurality of symbols are formed on the reel sheet 95 by printing.
The symbol forming area in the reel sheet 95 has a relatively high light transmittance, and when the LED in the backlight unit 91 is turned on, the light emitting area emits light brightly.

  The index sensor 55 is composed of, for example, a transmissive photosensor, and is attached to the tip end portion of a projecting portion 92t that projects from the base plate 92b to the reel drum 90 as shown in the figure. The index sensor 55 includes a light emitting portion 551 and a light receiving portion 552 that are arranged such that the light emitting surface and the light receiving surface face each other in the radial direction of the reel frame 93.

  In the case of this example, a predetermined spoke portion 93 s of the reel drum 93 is formed with a detected portion 93 d that protrudes in a direction facing the index sensor 55. The detected portion 93 d is formed at a position that passes through the space between the light emitting portion 551 and the light receiving portion 552 of the index sensor 55 as the reel drum 90 rotates.

  With such a configuration, depending on the index sensor 55 serving as a transmission type photosensor, the detected portion 93d is interposed between the light emitting portion 551 and the light receiving portion 552 once per rotation of the reel drum 90 (the rotating reel 4). As a result, a detection signal in which an ON pulse appears as the signal passes is obtained.

  Here, as shown in FIG. 7B, the detected part 93 d has one edge of both edges (ends) in a direction parallel to the rotation direction R (forward rotation direction) positioned at the same rotation angle as the origin position 101. Positioned to do so. Specifically, the detected portion 93 d of this example is positioned so that the edge on the rotation traveling direction side in the positive rotation direction (R) is positioned at the same rotation angle as the origin position 101.

The configuration for detecting the origin should not be limited to the one described above. For example, instead of the protrusion-like detected portion 93d, a configuration in which a detected portion by a notch as disclosed in JP 2014-33743 A may be provided. In this case, if the light emitting part 551 and the light receiving part 552 of the index sensor 55 are arranged so that the light emitted from the light emitting part 551 is received by the light receiving part 552 when the cutout part arrives as the rotating reel 4 rotates. Good.
The index sensor 55 is not limited to a transmissive photosensor, and a reflective photosensor can also be used.

Next, an example of the relationship between the driving method of each of the stepping motors 54a, 54b, 54c for rotating the rotating reels 4a, 4b, 4c and the symbols formed on the rotating reels 4a, 4b, 4c will be described.
In the present embodiment, the stepping motors 54a, 54b, 54c are unipolar driving stepping motors, each having two drive windings that are center-tapped. In the case of the present embodiment, the stepping motors 54a, 54b, 54c are driven by, for example, 1-2 phase excitation in which one-phase excitation and two-phase excitation are alternately repeated. The driving method using 1-2 phase excitation can realize smooth driving with a step angle halved compared with the driving method of one phase excitation or two phase excitation. The update period of the excitation pattern (excitation data) for 1-2 phase excitation is set to 1.49 ms, which is the timer interrupt processing period.

FIG. 8 is an explanatory diagram of symbols formed on the rotating reels 4a, 4b, and 4c.
In this example, 21 frames of symbols are arranged on the surface of the rotating reels 4a, 4b, 4c along the rotating direction. In each of the rotating reels 4a, 4b and 4c, there are 10 types of symbols (red 7, white 7, bar, character, cherry, watermelon, bell, replay, outage 1 and outage 2), and they are in a predetermined order. Are arranged in In the figure, the symbols of 21 frames formed on the rotating reel 4a are represented as symbols 4a1, 4a2,..., 4a21, respectively. Similarly, the symbols of 21 frames formed on the rotating reel 4b are represented as symbols 4b1, 4b2,..., 4b21, and the symbols of 21 frames formed on the rotating reel 4c are denoted as symbols 4c1, 4c2,. ing. The number given to the end of the symbol of each symbol represents the symbol number.

  In the rotating reels 4a, 4b, and 4c, the symbols are arranged at equal intervals, and in the drawings, the positions of the symbols are indicated by broken lines. In the rotating reels 4a, 4b, and 4c, a predetermined symbol break position is set as the origin position 101. The origin position 101 in this example is set to the symbol break position between the symbols 4a1, 4b1, 4c1, which are the first symbols, and the symbols 4a21, 4b21, 4c21, which are the 21st symbols, respectively.

  An arrow R in the figure represents the rotation direction of the rotating reels 4a, 4b, and 4c during steady rotation (during forward rotation). As understood from this, the numbers given to the symbols represent the order in which the symbols transition during the steady rotation starting from the origin position 101.

Here, in this example, the stepping motors 54a, 54b, 54c and the rotating reels 4a, 4b, 4c are respectively rotated so that the rotating reels 4a, 4b, 4c rotate 1/63 each time the stepping motors 54a, 54b, 54c rotate once. The rotation ratio between is set. In other words, it is necessary to rotate the stepping motors 54a, 54b, 54c 63 times in order to rotate the rotating reels 4a, 4b, 4c once.
In this example, since the number of drive steps necessary to rotate the stepping motors 54a, 54b, 54c is eight, the stepping motors 54a, 54b required to rotate the rotating reels 4a, 4b, 4c once. , 54c is set to 8 × 63 = 504.

Since the symbols of 21 frames are formed at equal intervals on the rotating reels 4a, 4b, and 4c in this example, the number of steps per symbol is 504 ÷ 21 = 24 steps.
Accordingly, a total of 24 positions can be detected as step positions for each symbol. Here, the step position in the symbol can be detected by decrementing the symbol step number (−1) for each timer interrupt process described later with reference to FIG. That is, the number of step positions detectable in each symbol is 24 (first step position) to 1 (last step position). When the number of symbol steps is further decremented from the state of reaching the final step position (No. 1) of the symbol, the symbol step number returns to No. 24 (= 0).

In addition, for each symbol, a predetermined step position among the 24 (0) to 1st step positions is defined as a position (stop permission step position) where the symbol should be permitted to stop. Specifically, the 8th step position is determined as the symbol stop permission step position. When the rotating reel 4 is stopped, a stop symbol is determined, and the rotating reel 4 is stopped at the stop symbol. At this time, the position at which the rotating reel 4 is stopped is not limited to any step position in the stop symbol. The stop is permitted in response to reaching the step position.

<4. Main processing>

Next, various processes executed by the CPU 80a of the main control board 40 will be described. The CPU 80a executes an infinite loop-shaped main process that is started mainly when the power is turned on, and a maskable timer interrupt process that is started at regular intervals by a periodic interrupt from the CTC 80e.

First, the main process executed by the CPU 80a will be described with reference to the flowchart of FIG.
When the power of the slot machine is turned on, the CPU 80a executes an initial setting process in step S101. Here, the state after the power is turned on is either a hot start by restarting the process executed before the power interruption, or a cold start by shifting to the process of step S102.
For example, if the clerk operates the setting key switch 72 described above and sets the winning probability of the lottery process before the start of business, a cold start process is performed, but there is no such clerk operation and there is an abnormality. If not detected, the game operation is hot-started.

Here, in the case of a hot start, the CPU 80a executes a predetermined power interruption recovery process in the initial setting process of step S101. As the power interruption recovery processing, a) When power interruption is a) Reel production b) When it is activated c) When activation is finished and it is in steady rotation d) Stop buttons 18a, 18b, 18c The processing corresponding to each of the cases after the operation is performed is executed. Specifically, in the case of a), various setting processes for redoing the reel effect from the beginning, in the case of b) or c), various setting processes for redoing the rotation reels 4a, 4b, 4c, d) In the case, various setting processes for restarting the stop control that has been executed in response to the stop operation before the power interruption are executed. In addition, since the specific content of the electric power interruption reset process performed corresponding to such a hot start is described also in Unexamined-Japanese-Patent No. 2013-212264 etc., please refer there for details.

  In response to the power interruption, the CPU 80a receives a signal for notifying the power supply supplied from the power supply board 41 and executes a non-maskable NMI (Non Maskable Interrupt) interrupt process. In this NMI interrupt process, a checksum operation for a predetermined area of the RAM 80c, holding of the calculated checksum value, setting of a backup flag, saving of a register value, and the like are executed. See JP 2013-212264 A and the like.

  On the other hand, in the case of a cold start, the CPU 80a repeats a series of main loop processes represented by steps S102 to S117. The main loop process of steps S102 to S117 is repeatedly executed for each game. In addition, the period of 1 game points out the period after rotating the rotation reel 4 and making it stop in the stop mode according to the lottery result.

  First, in step S102, the CPU 80a executes a RAM initialization process. That is, the predetermined area in the work area of the RAM 80c is cleared to zero.

In subsequent step S103, the CPU 80a generates a game state flag in the current game. The game state flag is a flag that specifies a game state such as whether the current game is “in bonus game”, “in bonus-winning” or “in normal game”.
In the following description, the normal game state and the bonus internal winning are collectively described as a normal game state, and an advantageous game state such as during a bonus game is described as a special game state.

Further, the CPU 80a executes a game medal insertion process in the next step S104. In other words, the inserted medal management process is executed for a medal actually inserted from the medal insertion slot 12 and a medal inserted in a pseudo manner by pressing the max insertion button 16. In this inserted medal management process, the number of medals inserted or pseudo-inserted is determined. After that, when the start lever 17 is turned on, the subroutine process is terminated.
At this time, according to the insertion of the medal, a control command (insertion command) indicating that is set in the transmission buffer in the effect control interface 86, and in the command output process (S205) of the timer interrupt process (FIG. 10) described later. Is transmitted to the production control board 42. At this timing, a clearing command indicating a clearing operation by the player may be transmitted.

  When the start lever 17 is turned on in step S104 and the inserted medal management process ends, the CPU 80a executes an internal lottery random number extraction process in step S105. Specifically, the counter value held in the counter circuit 81 is acquired. The acquired counter value is held as a random value at a predetermined address in the RAM 80c.

  In subsequent step S106, the CPU 80a executes an internal lottery process (design lottery process) based on the stored random number value. In the symbol lottery process, whether or not the bonus symbol is won, whether or not the small role symbol is won, and whether or not the replay symbol indicating replay is won is determined, and a control command ( A game start command) is set in the transmission buffer of the effect control interface 86, and is transmitted to the effect control board 42 by the command output process (S205) of the timer interrupt process. That is, the effect control board 42 is notified whether each symbol is won or not. Examples of small role symbols include “cherry symbols” (4a10, 4b3, 4c9), “bell symbols” (4a4, 4b5, 4c3, etc.), “watermelon symbols” (4a9, 4b12, 4c1, etc.), etc. can do.

  In response to the execution of the internal lottery process in step S106, the CPU 80a executes a reel effect lottery process for determining whether or not to execute a reel effect in the next step S107. The effects that can be selected in the reel effect lottery process are determined in accordance with the result of the internal lottery process. For example, if a predetermined symbol such as “watermelon symbol” is in an internal winning state, a predetermined reel effect such as “a slow effect that rotates in a positive direction and stops still” can be selected based on a predetermined winning probability. Become.

In response to execution of the reel effect lottery process in step S107, the CPU 80a initializes various data used in a symbol stop control process (step S409 in FIG. 13) described later as a stop symbol determination initialization process in the next step S108. After the execution, in the next step S109, a rotation rotation start setting process is executed to start the rotation of the rotary reels 4a to 4c.
The contents of the spinning rotation start setting process in step S109 differ depending on whether or not the reel effect lottery is won.
Here, the reel effect is executed at various timings, for example, according to the operation of the start lever 17. When the reel effect executed at the timing of operation of the start lever 17 is won, the reel effect is executed in accordance with the operation of the start lever 17 and the rotating reels 4a, 4b, 4c are temporarily stopped. After that, the rotating reels 4a, 4b, and 4c are activated (accelerated rotation) again to make a transition to a steady rotation state at a constant speed.
When the reel effect lottery is won, in the rotation rotation start setting process in step S109, various setting processes for starting the rotating reels 4a, 4b, and 4c for the normal rotation state after effect rotation is performed. Is executed.
On the other hand, when the reel effect lottery is not won, various setting processes for starting the rotating reels 4a, 4b, and 4c toward the steady rotation state are executed in the rotating rotation start setting process in step S109.
Details of the specific processing executed in step S109 will be described later with reference to FIG.

  By the way, when a certain reel effect is executed according to the operation of the start lever 17, it can be inferred that the player has won a predetermined symbol corresponding to the type of the reel effect. The player performs a stop operation so that the symbols targeted from such inference are aligned on the symbol stop line. Only when the inference is made and the stop timing is appropriate, the internal winning state is made effective and a predetermined medal is paid out.

In response to the execution of the rotation rotation start setting process in step S109, the CPU 80a executes the rotation rotation stop process in the next step S110.
In the rotation stop processing, processing for determining the stop symbol of the rotating reels 4a, 4b, 4c according to the operation of the stop buttons 18a, 18b, 18c, and stopping the rotating reels 4a, 4b, 4c with the stop symbol. Various data setting processing is performed. Further, in the spinning stop process, a process of collating the symbols stopped on the symbol stop line is also performed.
Note that the details of the specific process executed as the spinning cylinder stop process in step S110 will be described later with reference to FIG.

  In the above-described spinning cylinder stop process, the corresponding rotary reel 4 among the rotary reels 4a, 4b, and 4c is controlled to stop according to the result of the internal lottery process (S106). That is, as a result of the internal lottery process, the symbols of the rotating reels 4a, 4b, and 4c are aligned so as to match the winning result on condition that the player is appropriately stopped. However, if the timing at which the player presses the stop button 18 or the order of the stop operations is inappropriate, the player is stopped in a lost state pattern. As a result, the small winning combination at the corner is wasted, but the bonus winning is carried over after the next game. However, when a reel effect is executed, if a correct stop operation is executed in accordance with the suggestion, it is possible to avoid missing a medal.

The CPU 80a executes a winning determination process in the next step S111 in response to the execution of the spinning cylinder stop process in step S110. That is, based on the result of the above collation processing in the turning stop processing in step S110, it is determined whether or not the winning symbol (winning combination) is aligned on the symbol stop line, and the number of medals to be paid out according to the determination result Is calculated.
In the winning determination process, a winning information command is sent to the effect control interface 86 in order to send a control command (winning information command) indicating whether or not the winning symbols are aligned on the symbol stop line to the effect control board 42. Processing to set in the transmission buffer is also performed.
In the winning determination process, in order to cause the medal payout device 5 to execute the medal payout for the calculated payout number, a process of setting a control command instructing the medal payout based on the payout number to the transmission buffer in the payout connection interface 87 is also performed. Is called.

In the subsequent step S112, as the medal payout number monitoring process, the CPU 80a performs a process of counting the number of payout medals based on the detection signal of the medal payout sensor 76 and updating the credit value according to the medal payout.
In the medal payout number monitoring process, a process of setting a payout command in the transmission buffer in the effect control interface 86 is also performed in order to transmit a control command (payout command) indicating medal payout to the effect control board 42.

  Further, in the next step S113, the CPU 80a executes a re-game setting process. In the replay setting process, it is determined whether or not the replay winning state is set. If the replay winning state is set, the replaying operation start process is executed, and the process proceeds to step S114. If it is not in the replay winning state, the process proceeds to step S114 without executing the replay operation start process.

  In step S114, the CPU 80a determines whether or not the bonus game is currently being played. If the bonus game is in progress, the CPU 80a executes a predetermined process corresponding to the case in which the bonus is being operated as the bonus operating process in step S116, and then returns to the previous step S102.

On the other hand, if the bonus game is not currently being played, the CPU 80a determines in step S115 whether or not a bonus symbol has been prepared. After performing various corresponding setting processes, the process returns to step S102.
When the bonus symbols are not prepared, the CPU 80a passes the bonus operation start process of step S117 and returns to step S102.

<5. Timer interrupt processing>

Next, timer interrupt processing started every 1.49 ms will be described with reference to FIG.
First, the CPU 80a saves the register value in step S201 (register saving process), acquires the data of the input port that receives various switch signals and sensor signals in step S202, and stores it in a predetermined area of the RAM 80c, for example (see FIG. Port input processing). The sensor signal includes a medal passage sensor 67, a medal payout sensor 76, each index sensor 55 of the first cylinder index sensor 55a, the second cylinder index sensor 55b, and the third cylinder index sensor 55c, a door sensor 66, and the like. The detection signal from is included. In the port input process, a random number value is also fetched from the counter circuit 81.

  Next, the CPU 80a executes a rotating cylinder rotation control process in step S203. In the rotation rotation control process, the rotation reel 4 is driven from the start rotation to the stop based on the setting data in the rotation rotation start setting process (S109) and the rotation rotation stop process (S110) in the main process of FIG. In order to realize this, the excitation data output to the stepping motors 54a, 54b, 54c is set in an output buffer prepared in the RAM 80c.

  In step S204, the CPU 80a executes update processing for various target timers as regular update processing, and then executes command output processing in step S205. That is, the control command set in the transmission buffer in the effect control interface 86 is output to the effect control board 42 for each byte.

In the next step S206, the CPU 80a updates the display operation of various lamps as display / motor output processing, and outputs the excitation data set in step S203 to the stepping motors 54a, 54b, 54c via the rotary motor driving unit 85. . When excitation data is output to the stepping motor 54, each stepping motor enters a predetermined excitation state corresponding to the excitation data, and the rotation reel 4 is rotated or stopped by updating the excitation data.
The lamps updated in step S206 include lamps provided as the LED group 9 (for example, LEDs indicating that the rotation of the rotating drum is ready, LEDs indicating a medal insertion acceptance state, and the like). LED indicating the number of medals).

  Further, the CPU 80a executes an abnormality monitoring process in the next step S207, and executes an external information signal output process in step S208. In the abnormality monitoring process in step S207, determination of the presence / absence of abnormality based on the detection signals of the lever detection sensor 68, the medal payout sensor 76, and the door opening sensor 35 described above and processing according to the determination result are executed. The external information signal output process in step S208 is a process related to information output via the external concentration terminal board 70 described above, and specifically, a process of outputting information such as paid-out medals to the hall computer is executed. To do.

In the subsequent step S209, the CPU 80a confirms the max input button valid flag. If the max input button valid flag is “1” (on), the CPU 80a determines whether the max input button 16 is operated in step S210. Note that the max insertion button valid flag is a flag that is turned on when the number of coins necessary for one game has been inserted, and is turned off (“0”) in other cases.
In step S210, if the max input button 16 has been operated, the CPU 80a sets a maximum input operation command in step S211 and proceeds to step S212.

  On the other hand, if the maximum input button valid flag is “0” in step S209, or if the maximum input button 16 has not been operated in step S210, the CPU 80a proceeds directly to step S212.

In step S212, the CPU 80a restores the register value saved in the previous step S201. In response to the execution of the register restoration process in step S212, the CPU 80a finishes the timer interrupt process.

<6. Processing related to rotation and stop of rotating cylinder>
[6-1. Cylinder control flag]

Next, processing related to rotation and stop of the rotating reels 4a to 4c will be described.
First, the spinning cylinder control flags FGa to FGc used in the processing relating to the rotation and stop of the rotary reels 4a to 4c will be described.
In the present embodiment, corresponding to the three reels 4a to 4c, 1-byte length (8-bit length) spinning cylinder control flags FGa to FGc are prepared, and each of the spinning cylinder control flags FGa to FGc is prepared. Based on the value of the bite, the rotation of the production rotation and the rotation operation from the start rotation (acceleration rotation) to the complete stop is performed.

FIG. 11A illustrates the data structure of the spinning cylinder control flags FGa to FGc.
Each of the spinning control flags FGa to FGc is a 1-bit control flag F0, a reel production flag F1, a spinning sensor ON flag F2, a stop command flag F3, a stop signal detection flag F4, and a spinning start flag. It consists of 8 bits, F5, a rotation start flag F6, and a rotation stop flag F7. The bit position of each flag F matches the bit position indicated by the number assigned to the flag F.

FIG. 11B is an explanatory diagram regarding the significance of the flags F7 to F0.
The in-control flag F0 indicates whether or not the rotation reel 4 is under rotation control, and F0 = from the start of rotation by the ON operation of the start lever 17 to the complete stop state according to the ON operation of the stop button 18 1 The reel effect in-progress flag F1 indicates that the reel effect is in effect rotating the rotating reel 4 irregularly by F1 = 1. The rotating cylinder activation flag F6 indicates that the activation operation for accelerating the rotating reel 4 to a rotating state at a constant speed as steady rotation is F6 = 1. The spinning cylinder activated flag F5 indicates that the rotating reel 4 that has been activated is normally rotated by F5 = 1.

The stop signal detection flag F4 is set to F4 = 1 when it is detected that the player has operated the stop button 18, and the stop command flag F3 is subjected to the rotation of the main process through the subsequent slip control. F3 = 1 in response to the arrival of the stop symbol detected in the stop process (S110).
The spinning cylinder stop flag F7 becomes F7 = 1 in response to arrival at a predetermined stop execution step position (step position where brake control (all-phase excitation) is started to stop the rotating reel 4) in the stop symbol. . Note that the spinning stop flag F7 is set to F7 = 0 by setting the spinning control flag FG = 01h before the rotation reel 4 is started in step S307 described later with reference to FIG.

Further, the rotation sensor ON flag F2 is set to F2 = 1 in response to the index sensor 55 being turned ON every time the origin reel position 101 is reached after each rotating reel 4 starts rotating. The rotation sensor ON flag F2 defines whether or not to accept a stop operation by the player, and the stop operation after F2 = 1 is accepted as an effective stop operation.

[6-2. Processing from rotation start to steady rotation]

The rotating operation and the stopping operation of the rotating reels 4a to 4c are performed in the rotating rotation start setting process (S109) and the rotating cylinder stop process (S110) in the main process shown in FIG. 9, and in the timer interrupt process shown in FIG. This is realized by cooperating with the cylinder rotation control process (S203).
Hereinafter, the rotation rotation start setting process, the rotation rotation stop process, and the rotation rotation control process will be described separately from the viewpoint of rotation start to steady rotation and rotation stop.

First, the rotation rotation start setting process will be described with reference to the flowchart of FIG.
In FIG. 12, the CPU 80a acquires a reel effect flag in step S301, and determines whether or not a reel effect lottery is won in step S302. The reel effect flag is a flag that represents the lottery result of the reel effect lottery process (S107) in the main process of FIG.

  If the reel effect lottery is won, the CPU 80a executes a reel effect start setting / standby process in step S303. That is, a necessary setting process for starting the effect rotation is executed, such as setting an effect table corresponding to the type of reel effect selected from the effect tables prepared in advance for each of the stepping motors 54a, 54b, 54c. At the same time, it waits until the effect rotation is completed. In the reel effect start setting / standby process, 03h is set in the spinning control flag FG of the rotating reel 4 on which the reel effect is executed. That is, it indicates that the corresponding rotating reel 4 is under rotation control and is in the reel effect.

  In addition, the process for rotation control based on the selected effect table is executed in the rotating cylinder rotation control process (S203) in the timer interruption process shown in FIG.

When the reel effect start setting / standby process at step S303 is completed (that is, when the reel effect is completed), or when a negative result that the reel effect lottery is not won is obtained at the previous step S302, the CPU 80a. After executing the wait timer acquisition process in step S304 and the specified number of interrupts waiting process in step S305, the wait timer is set to 4.1 s in the next step S306. By setting this wait timer, a time count of 4.1 s is started.
Here, 4.1 s is a time length that should be at least as a time interval between games. Thus, by setting the minimum interval as the time interval between games, it is possible to prevent the player from excessively consuming medals.
In the wait timer acquisition process of step S304, the value of the wait timer that has been started by the timer set process of step S306 executed one game before is acquired. In the waiting process of step S305, the waiting for the number of timer interruptions (acquired wait timer value ÷ 1.49ms) corresponding to the value of the acquired wait timer is performed.
As a result, the interval between games is at least 4.1 seconds or longer.
Note that 4.1 s is an example, and can be changed as appropriate.

  In response to the execution of the timer setting process in step S306, the CPU 80a sets the spinning cylinder control flags FGa to FGc to 01h in step S307. Here, the spinning cylinder control flag FG = 01h means that the in-control flag F0 = 1 and the other flags F1 to F7 are all 0. Since only the in-control flag F0 is set to “1” in this way, the three reels 4a to 4c are activated toward the steady rotation by the rotation rotation control process (S203) of the timer interrupt process thereafter. Control is started.

  In next step S308, the CPU 80a sets a motor operation table for activation. The motor operation table is provided to realize motor operation for accelerating rotation of the stepping motors 54a to 54c toward steady rotation. The excitation data output to the motor and the length of time for outputting the excitation data are provided. A table having associated information.

  Subsequently, in step S309, the CPU 80a clears the re-game operation state bit and turns off the re-game LED. Note that the re-game operation state bit is set to a predetermined value (for example, 1) when the re-game is selected in the re-game setting process in step S113 executed corresponding to the previous game.

In subsequent step S310, the CPU 80a sets a rotation start command in the transmission buffer in the effect control interface 86, and ends the rotation rotation start setting process shown in this drawing.

[6-3. Processing related to stop of rotating cylinder]

Next, a process related to stopping the rotating reel 4 will be described.
Since the acceptance of the stop operation of the rotating reel 4 is performed by the turning stop processing (S110) in the main processing shown in FIG. 9, the turning stop processing in step S110 will be described first.

FIG. 13 is a flowchart of the spinning cylinder stop process in step S110.
In FIG. 13, the CPU 80a first waits until one interrupt process is completed in step S401.
Here, in step S109 immediately before the spinning cylinder stop process in step S110, the spinning cylinder rotation start setting process is executed. As understood from the above description, the rotation of the rotating reels 4a to 4c is performed in the rotation rotation control process in the first timer interruption process after the necessary setting is performed in the rotation rotation start setting process in step S109. This is started by executing (S203). Therefore, the standby process in step S401 functions as a process of waiting until the rotating reels 4a to 4c start rotating.
Note that the standby process in step S401 is executed a plurality of times in the course of the process shown in FIG. The standby process of step S401 executed after the second time functions as a process of waiting for the rotation control process (S203) to be performed once, that is, for the rotation control to proceed for one timer interrupt.

  In response to performing the standby process in step S401, the CPU 80a determines the rotation sensor ON flag F2 corresponding to the rotating cylinder (rotary reel 4) in step S402, and in the subsequent step S403, the rotation sensor ON flag F2 is determined. Are all ON (= 1), that is, whether or not the origin position 101 has been detected for all the rotating reels 4.

  If the condition that the rotation sensor ON flag F2 is all ON is not satisfied, the CPU 80a turns on the stop button LEDs of the stop buttons 18a to 18c in red in step S417, and returns to step S401. Note that red lighting indicates that acceptance of a stop operation is prohibited.

On the other hand, when the condition that all the rotation sensor ON flags F2 are ON is satisfied, the CPU 80a determines whether or not an invalid operation is performed in step S404. That is, it is determined whether or not an invalid operation other than an effective stop operation of pressing one of the stop buttons 18a to 18c is being performed.
If an invalid operation has been performed, the CPU 80a turns on the stop button LEDs of the stop buttons 18a to 18c in red in step S417, and returns to step S401.

If an invalid operation has not been performed, the CPU 80a determines whether or not a valid stop operation has been performed in step S405, and if a valid stop operation has not been performed, the rotating reel 4 being rotated in step S418. The stop button LED corresponding to is turned on in blue, and the process returns to step S401.
On the other hand, when a valid stop operation is performed, the CPU 80a turns on all the stop button LEDs related to the stop buttons 18a to 18c in step S406.

Here, paying attention only to the lighting control of the stop button LED, after all the stop button LEDs of the stop buttons 18a to 18c are lit red in step S406, have all the rotating reels 4 been stopped in step S412? It is determined whether or not all the rotating reels 4 have been stopped, the process returns to step S401 and the above-described processing relating to the blue lighting / red lighting is executed.
With this processing flow, after the rotation of the rotating reels 4a to 4c is started, the lighting control of the stop button LED is performed as follows.

-Until the stop operation can be accepted from the start of rotation (reel production start or start start), all the stop buttons LED are kept lit red.
・ When stop operation is accepted, all stop button LEDs are lit in blue. However, when an invalid operation is performed, all the stop button LEDs are lit red.
・ When the stop operation of the rotating reel 4 is performed, all the stop button LEDs are once lit red, and then only the stop button LED of the stop button 18 of the rotating reel 4 on which the stop operation is performed is kept red. The stop button LED of the stop button corresponding to the other rotating reel 4 is returned to blue. At this time, if there is no rotating reel 4 that is rotating, all of the stop buttons LED remain in a red-lit state.

Continue to explain the process.
As described above, in step S405, it is determined that a valid stop operation has been performed. In step S406, the stop button LED of the stop buttons 18a to 18c is lit red. Set F4 = 1.

  Subsequently, in step S408, the CPU 80a executes various variable update processing. Specifically, the stop interval timer is set to 211 ms. 211 ms corresponds to the time for four frames, which is the maximum number of sliding frames.

  In response to the execution of the variable update process in step S408, the CPU 80a executes a symbol stop control process in step S409. This symbol stop control process determines (calculates) a stop position including the stop symbol for the rotating reel 4 on which the stop operation has been performed, and sets a stop command flag F3 = 1 in response to reaching the stop symbol. The main processing content is to collate symbols on an effective symbol stop line. Further, the CPU 80a outputs a stop operation reception information command for notifying the effect control board 42 that the stop operation has been received in step S409.

  In response to the execution of the symbol stop control process of step S409, the CPU 80a advances the process to step S410, and as the stop result information command set process, the effect control is performed to send a stop result information command representing the stop result to the effect control board 42. Set to the transmission buffer in the interface 86.

  In subsequent step S411, the CPU 80a waits until the stop interval timer = 0. By the standby process in step S411, the standby until the time of 211 ms elapses after the stop interval timer is set in the previous step S408 is realized. Due to such standby, a time corresponding to the maximum number of sliding frames is always ensured after the stop operation is performed until the stop operation for the next rotating reel 4 can be accepted.

  In response to the execution of the standby process in step S411, the CPU 80a determines in step S412 whether or not all of the rotating reels 4 have been stopped, and all of the rotating reels 4 have not been stopped (that is, stopped. As described above, the process returns to step S401. If all the rotary reels 4 have been stopped, the process proceeds to step S413.

In step S413, the CPU 80a acquires input information about the stop buttons 18a to 18c, the start lever 17, the max insertion button 16, the credit settlement button 14, and the door opening sensor 35 as input port information acquisition processing. Next step In S414, it is determined whether any of the operations corresponding to the input information is performed.
When any operation is performed, the CPU 80a executes the information acquisition process in step S413 and the determination process in step S414 again. That is, as long as any operation is performed, the process loops in steps S413 → S414 → S413.

  If no operation has been performed, the CPU 80a proceeds to step S415, sets a predetermined value (101 ms in this example) to the wait timer as a wait timer setting process after all stop, and waits for a specified number of interrupts in the subsequent step S416. Execute. As the designated number interrupt waiting process, a process of waiting until the timer interrupt process corresponding to the number of times corresponding to the value of the wait timer set in step S415 is executed.

In response to the execution of the standby process in step S416, the CPU 80a finishes the rotating cylinder stop process shown in FIG.
Note that the actual rotation of the reel 4 is stopped in the spinning rotation control process (S203) of the timer interrupt process in response to the setting of the stop command flag F3 in the symbol stop control process (S409) of the main process. Is performed by outputting an excitation pattern for the stepping motor 54 corresponding to the rotating reel 4. In addition to the fact that the stop pattern has been reached (= 1 is set in the stop command flag F3), the excitation pattern output for this stop has reached the predetermined number of symbol steps (monitored in step S203). It is made according to.

<7. About state transitions related to fluctuations>

State transitions related to fluctuations are defined with reference to FIG.
First, as shown in FIG. 14A and FIG. 14B, the state of the slot machine when the player is playing the slot machine is “change waiting” and “change” from the viewpoint of whether or not it is changing. It is divided into “medium”, “floating suspension”, and “interruption production”.
“Waiting for change” means that the three reels 4a, 4b, 4c start rotating after the player inserts medals into the medal slot 12 (including pseudo insertion of medals after winning the replay) (that is, the start lever). 17).
Fluctuating means a state in which the player starts rotating the three rotating reels 4a, 4b, 4c and stops the three rotating reels 4a, 4b, 4c.
In the variable stop state, the medal is inserted into the medal slot 12 in order to start the next game after the three rotating reels 4a, 4b, 4c are stopped (that is, from the time when the changing state is finished). (That is, a state in which the stop mode of each rotary reel 4 according to the player's operation of the start lever 17 is presented to the player).
Except for the interruption production, the game progresses by repeating the states of waiting for change, changing, and stopping change.
“Interrupting effect” means that a freeze effect is in progress, and is a state where the state is changing, during stoppage of change, or at the timing of switching of each state. In other words, the transition to the state of the interruption effect is made at a predetermined timing during the change, the case returns to the state of the change when the state of the interruption effect ends, or the state of the interruption effect at the time of switching from the change to the change stop There are cases where the
The freeze effect is executed during the interruption effect.
FIG. 14 shows the state transition when the freeze effect is executed.

  Specifically, the timing for transitioning to the state during the suspension effect related to the freeze effect is when the transition to the state during the suspension effect is performed at the timing when the start lever 17 is operated (FIG. 14A), or the three rotating reels 4a and 4b. There is a case where a transition is made to an interrupted effect state when the stop button 18 for stopping the first rotating reel 4a (or 4b or 4c) of 4c is pressed (FIG. 14B). In addition, when the three rotating reels 4a, 4b, and 4c are all stopped, the state is changed to a state where the suspended effect is being performed, or the state is changed to the state where the suspended effect is being performed immediately before the medal is paid out, or the medal is paid out. In some cases, a transition is made to a state in which an effect is interrupted between the time when the medal is inserted and the time when the medal is inserted. In the case of transitioning to a state where an interruption effect is being triggered when the stop button 18 is pressed as shown in FIG. 14B, for example, the current rotation state (only one rotation reel is stopped and two rotation reels are rotating). While maintaining the (state), an effect in which the operations of the remaining two stop buttons 18, 18 are invalidated is performed. In response to this, a character effect on the LCD unit 7 or a lamp effect by LED is executed during the interruption effect. As a result, the player cannot stop the remaining two rotating reels, and the state of the suspended effect continues until the end of the various effects, so that the various effects can be shown to the player until the effect ends.

In the normal gaming state and the special gaming state (for example, during the BB game or ART game), the states of “waiting for change”, “during change”, “during change stop”, and “during interruption” Can exist.
Further, one game (one change) is defined as the state in which the change is in progress until the state in which the change is in progress ends (a state in which a suspended effect is in effect may be sandwiched).
In the meantime, in particular, the state from when the pressing of the stop button 18 becomes valid until the rotating reel 4 stops is defined as “corresponding to stop control”.

Each of the above states (waiting for change, changing, changing stop, and interruption effect) is switched by the main control board 40 and notified to the effect control board 42 as necessary. For example, the change from the change to the change stop can be notified by the stop result information command set process in step S410 described above.

<8. First Embodiment>
[8-1. Game state and ceiling]

The gaming state and ceiling of the slot machine will be described with reference to FIG.
The gaming state of the slot machine includes a normal gaming state and a special gaming state that is more advantageous than the normal gaming state.
Examples of the special game state include a state in which a bonus game, AT, RT, ART, or the like is being executed.

In addition, a ceiling is provided to prevent the player from quitting the game as a result of continuing the normal gaming state for a long time by continuing to defeat the special gaming state lottery.
Specifically, the counting object is counted and a special game is activated when the count reaches a predetermined value (ceiling value).
When the count is reset to 0 when the count reaches a predetermined value, one ceiling value is provided as a fixed value. That is, counting is started from 0, and when the special game is activated when the ceiling value is reached, the special game ends and the counting starts again from 0.
The ceiling value may be provided as a fluctuating value. That is, when the count is reset to 0, the ceiling value is set as 1000, but it decreases to 999, 998,... ,... May increase. Specifically, there are an example in which the ceiling price is decreased according to the establishment of a specific small role, and an example in which the ceiling price is increased when a designated game procedure such as the stop order of the stop button 18 is not followed.

  If the count is not reset to 0 when the count reaches a predetermined value, the ceiling value is relatively provided. Specifically, a value obtained by adding 1000 to the current count is provided as a ceiling value at a specific opportunity. For example, when a specific opportunity comes when the count number is 300, 1300 (300 + 1000) is set as the ceiling value. Furthermore, when a specific opportunity comes again at 800, the ceiling price is updated from 1300 to 1800 (800 + 1000).

Here, a specific example of a count target is given. Examples of the count target include the number of games, a specific small role, and the number of executions of a specific effect. In each example shown below, an example in which the number of games is used as a count target will be described.
The count of the count target is executed by the CPU 80a of the main control board 40, and the count number is stored in the RAM 80c, for example. The ceiling value is stored in the ROM 80b or the RAM 80c.
The effect control board 42 may execute the count to be counted, the count number may be stored in the RAM of the effect control board 42, and the ceiling value may be stored in the ROM or RAM of the effect control board 42.

An example of the game type and ceiling described above will be described with reference to FIG.
The special game lottery is won in the 142nd game after the normal game is started, and BB as a special game is started. When the special game (BB) ends, the count of the number of games is reset to 0, and the transition to the normal game state is made again. Thereafter, when the count value of the number of games reaches 1000 without reaching the special game lottery and reaches the number of ceiling games (ceiling value), ART as a special game is started. In ART, for example, 10 games are set as one set, and one or a plurality of sets are continuously executed. In the example shown in FIG. 15, two sets are executed across the normal game state of seven games.

In the following description, the special game lottery in the normal game state is referred to as a first special game lottery, and the special game lottery when reaching the ceiling is referred to as a second special game lottery. However, when reaching the ceiling, it is determined to execute a specific special game, and the second special game lottery may not be executed.
In addition, the special games to be selected in the first special game lottery are BB, RB, RT, AT, ART, and the like. Of course, only one of them may be a lottery object, some may be a lottery object, or all may be a lottery object.
Furthermore, the special games to be selected in the second special game lottery are RT, AT, ART, and the like.

  The second special game lottery executed on the ceiling is a lottery that determines the number of sets and the continuation rate of special games to be drawn. At this time, after performing the winning lottery to win 100%, a lottery for determining the number of sets and the continuation rate (hereinafter referred to as a “lottery lottery”) may be performed. Good.

The special game executed by the first special game lottery is referred to as the first special game, and the special game executed by the second special game lottery is the second special game.
The first special game need not be the same type of special game every time. For example, if BB is won by the first special game lottery and BB is executed as the first special game and then ART is won by the next first special game lottery, the ART is executed as the first special game. The That is, the special games won in the normal game state are collectively referred to as the first special game, and the special games executed when the ceiling is reached are collectively referred to as the second special game.

[8-2. About special gaming state and gaming value]

Here, the relationship between the special game state and the game value will be described.
The game value is a value given to the player as a result of the game, and refers to a medal to be paid out or a replay game in which the next game can be played without using a medal.
First of all, a normal game and a special game are provided as game modes, and examples of the special game include a slot machine provided with BB (first type special game), RB, and ART (second type special game). explain. At this time, any one of BB, RB, and ART is executed as the first special game, and ART is executed as the second special game.
The table of FIG. 16 shows the average acquired number of sheets and the average net increase number as basic game value information of BB, RB, and ART. In other words, it represents a relationship between game values expected to be acquired in each game state. Note that ART is a numerical value when one set (= 10 games) is played.
According to FIG. 16, BB has an average acquired number of sheets of 315 and an average net increase of 294 sheets.
Here, the acquired number is the total number of medals to be paid out during the BB. The acquired number is 315, for example, when a small role with a payout number of 15 is arranged 21 times. . The net increase number is a value obtained by subtracting the inserted number from the payout number, and the net increase number is 294. For example, when a series of actions is performed 21 times.
Further, RB has an average acquired number of 98 sheets and an average net increase of 84 sheets. Furthermore, in ART (one set), the average number of acquired sheets is 44, and the average net increase is 20.
In the following description, an example based on these numerical values will be described.

[8-3. Ceiling setting example 1]

In setting example 1, paying attention to a value VA1 obtained by simply averaging the average acquired number of BB, RB, and ART, a lottery is performed on the ceiling so that the average acquired number is smaller than VA1.
FIG. 17A is a distribution table that defines the distribution of the number of sets when the ART is won in the first special game lottery (that is, in the normal game state). Note that the distribution table may not include information on the average acquired number of sheets and the average net increase number. The same applies to other sorting tables.
When the lottery for distributing the number of ART sets is performed based on the table of FIG. 17A, the average is 3.35 sets, and the expected value of the average number of acquisitions (the number of medals expected to be acquired by ART) is 147.4 average The net increase is 67 sheets.
Based on this, as the game value information of BB, RB, and ART, FIG. 17B shows the number of acquired and net increase expected when winning each game state. The average acquired number and average net increase expected when the ART is won are the same as the average acquired number and average net increase obtained when playing 3.35 sets.

In addition, you may prescribe | regulate including not only the table which prescribed | regulated only the distribution of the number of sets but the winning probability. Specifically, the lottery table shown in FIG. 17C may be defined as a table in which the winning probability is 1/300 and the distribution of the number of sets when winning is the same as in FIG. 17A. In this case, the probability that the number of sets is 1 is (1/300) × (30/100) = 30/30000 because the winning probability is 1/300 and the distribution probability is 30%. Has been.
In summary, when an ART is won, a lottery may be made based on the table of FIG. 17A, or a lottery may be made based on the table of FIG. 17C including whether or not the ART is won.
This also applies to other examples below. In the following other examples, the table corresponding to FIG. 17C and the description are omitted, and the table corresponding to FIG. 17A is shown and described.

As described above, the average number of acquired BB, RB, and ART is 315, 98, and 147.4 as shown in FIG. 17B. The value VA1 obtained by further averaging these is (315 + 98 + 147.4) /3=186.8 sheets. Therefore, in the sorting lottery on the ceiling (second special game lottery), the lottery may be performed so that the average number of sets is smaller than 186.8 / 44 (≈4.24) sets.
Specifically, as shown in FIG. 18A, a distribution lottery with an average number of sets of 4.0 may be performed. When the ART sorting lottery based on the table of FIG. 18A is executed when the ceiling is reached, the expected value of the average number of ARTs acquired by the second special game lottery is 176 (<186.8) (See FIG. 18B).

[8-4. Ceiling setting example 2]

In setting example 2, attention is paid to the average value VA2 of the average acquired number of sheets in consideration of the appearance rates of BB, RB, and ART.
FIG. 19A shows the winning probabilities of BB, RB, and ART in the first special game lottery. According to the winning probability, each special game is drawn when the start lever 17 is operated. The winning probability of BB is 1/400, the winning probability of RB is 1/300, and the winning probability of ART is 1/250. It becomes. When ART is selected, an average of 3.35 sets (average 33.5 games) of ART will be started.
The average acquired number of sheets VA2 including the winning probability is calculated based on the appearance probability of BB, RB, and ART. That is, when winning a special game of BB, RB, or ART, the proportion of BB is about 25.4%, the proportion of RB is about 33.9%, the proportion of ART is about 40.7%, Based on this, VA2 = 315 × 0.254 + 98 × 0.339 + 147.4 × 0.407≈173.3 is calculated.

Therefore, in the sorting lottery on the ceiling, the lottery may be performed so that the average number of sets is less than 173.3 / 44 (≈3.94 sets).
Specifically, when reaching the ceiling, an ART distribution lottery based on the table of FIG. 19B (that is, an ART distribution lottery with an average set number of 3.0) is executed. Thereby, the expected value of the average number of acquired ARTs executed by the second special game lottery is about 132 (<173.3) (see FIG. 19C).

[8-5. Ceiling setting example 3]

In setting example 3, attention is paid to the minimum average acquired number of sheets VA3 among the average acquired number of sheets of BB, RB, and ART.
In the ART allocation lottery in the first special game lottery in the setting example 3, the distribution table in FIG. Accordingly, the average number of acquired BB, RB, and ART in the first special game lottery is as shown in FIG. 17B.
Here, the minimum average acquired number of sheets VA3 is 98 which is the minimum value among 315, 98 and 147.4.

Therefore, in the sorting lottery on the ceiling, the lottery may be performed so that the average number of sets is less than 98/44 (≈2.23) sets.
Specifically, when reaching the ceiling, an ART distribution lottery (that is, an ART distribution lottery with an average set number of 2.0) based on the table of FIG. 20A is executed. Thereby, the expected value of the average number of acquired ARTs executed by the second special game lottery is 88 (<98) (see FIG. 20B).

In setting example 3, the average acquired number based on the average number of sets is taken as an example of the average acquired number of ARTs. However, the average acquired number based on the minimum number of sets of ART may be used as a comparison target.
Specifically, an example of using the distribution table shown in FIG. 21A in the ART distribution lottery in the first special game lottery is shown.
In the sorting table of FIG. 21A, the minimum number of sets is 2. That is, the minimum average acquired number of sheets VA3 ′ is 88 which is the minimum value among 315, 98, and 88.

Therefore, in the sorting lottery on the ceiling, the lottery may be performed so that the average number of sets is less than 88/44 (= 2.0) sets.
Specifically, when reaching the ceiling, an ART distribution lottery based on the table of FIG. 21B (that is, an ART distribution lottery with an average set number of 1.95) is performed. Thereby, the expected value of the average number of acquired ARTs executed by the second special game lottery is set to 85.8 (<88) (see FIG. 21C).

[8-6. Ceiling setting example 4]

In setting example 4, paying attention to the average value VA2 of the average acquired number of sheets taking into account the appearance rates of BB, RB, and ART, the ceiling is obtained so that the average acquired number of ARTs executed with the ceiling becomes smaller than VA2. Although the ART distribution lottery is executed, an example will be described in which the maximum number of sets to be distributed is higher in the ceiling ART distribution lottery than in the first special game lottery.

Specifically, in the first special game lottery, a distribution lottery using the distribution table of FIG. 17A is executed.
Further, in the second special game lottery, a distribution lottery using the distribution table of FIG. 22A is executed.
As a result, the maximum number of sets that can be distributed is 10 in the first special game lottery, whereas it is 20 in the second special game lottery. That is, the maximum average number of ARTs executed by the second special game lottery is 44 × 20 = 880, which is based on BB (315), RB (98) and ART (440 in 10 sets). Will also increase.
However, the expected value (143) of the average acquired number of ARTs executed by the second special game lottery is smaller than the average value VA2 (173.3) of the average acquired number including the appearance rate (FIG. 22B).

In the setting example 4, the average value VA2 of the average acquired number of sheets including the appearance rate is given as an example for comparison. VA3 ′ may be a comparison target. In that case, the probability of the sorting table of FIG. 22A may be set so as to be lower than the respective values to be compared.

[8-7. Ceiling setting example 5]

In setting example 5, paying attention to the average value VA2 of the average acquired number of sheets including the appearance rates of BB, RB, and ART, the average acquired number of ARTs executed with the ceiling as a trigger is greater than VA2, but is distributed. An example in which the maximum number of sets is reduced will be described.

Specifically, in the first special game lottery, a distribution lottery using the distribution table of FIG. 23A is executed. In this case, the average number of ART sets in the first special game lottery is 3.5 sets, and the average number obtained is 154. Accordingly, the average value VA2 of the average number of acquired images including the appearance rate is about 175.about. From 315 (about 25.4%), 98 (about 33.9%), and 154 (about 40.7%). It is calculated as 9 sheets. In addition, the maximum average number obtained in the first special game lottery is 1320 when 30 sets of ART are won.
On the other hand, in the second special game lottery, a distribution lottery using the distribution table of FIG. 23B is executed. In this case, as shown in FIG. 23C, the maximum average acquired number of ARTs executed by the second special game lottery is 880 (<1320) when 20 sets are won. Further, the average number of ARTs executed by the second special game lottery is 5 sets, and the average acquired number is 220 (> 175.9).
Therefore, a special game with a ceiling as an opportunity is expected to have an average number of acquisitions higher than the special game won in normal games, but since the maximum average acquisition number is reduced, the ceiling has excessive game value. It is possible to prevent an acquisition opportunity (30 sets of ART in setting example 5).

In the setting example 5, the average value VA2 of the average acquired number of sheets taking into account the appearance rate is given as an example for comparison. VA3 ′ may be a comparison target.

[8-8. Ceiling setting example 6]

In setting example 6, attention is paid to the volume zone of ART (the number of sets with the maximum distribution probability) as the representative performance of ART.
First, when the distribution table of FIG. 24A is used in the first special game lottery, the average value VA2 of the average acquired number of sheets including the appearance rates of BB, RB, and ART is about 192.1. Furthermore, the maximum average number obtained is 880 when 20 sets are won.
On the other hand, when the distribution table of FIG. 24B is used in the second special game lottery, the average set number of ART executed by this is 5.4 sets, and the average acquired number is 237.6. In addition, the maximum average number obtained is 1320 when 30 sets are won.
That is, both the expected value of the average acquired number of games and the maximum average acquired number of games are more in the special game executed by the second special game lottery.

However, when paying attention to the ART volume zone, the volume zone of the ART distribution lottery set number in the first special game lottery is three sets, and the volume zone of the ART distribution lottery set number in the second special game lottery is two. Set.
Therefore, in the first special game lottery, BB, RB, and ART each of the average number of acquisitions and the ratio of appearance rate are 315 (about 25.4%), 98 (about 33.9%), 132 (about 40.7%), and the average value VA2 of the average number of acquired sheets in consideration of the appearance rate is 167 sheets. Furthermore, the expected value of the average number of acquired ARTs executed by the second special game lottery is 88 (2 sets) as shown in FIG. 24C.
As a result, the special game triggered by the ceiling is less expected than the special game won in the normal game when the focus is on the volume zone.

In the setting example 6, the average value VA2 of the average acquired number of sheets including the appearance rate is given as an example for comparison, but the value VA1 obtained by simply averaging the average acquired number of sheets, the minimum average acquired number of sheets VA3, or VA3 ′ may be a comparison target.

[8-9. Ceiling setting example 7]

In setting example 7, the case where the same distribution table is used in the ART distribution lottery in the first special game lottery and the ART distribution lottery in the second special game lottery will be described.
Specifically, the distribution table shown in FIG. 17A is used.
At this time, the average acquired number of BB, RB, and ART in the first special game lottery is BB (315), RB (98), and ART (147.4). The average value VA2 of the average acquired number of sheets, including the appearance rates of BB, RB, and ART, is about 173.3 sheets.
On the other hand, the expected value of the average acquired number of ARTs executed by the second special game lottery is 147.4.
In other words, even if the same sorting table is used, the special game triggered by the ceiling has a lower expected value of the average number of acquisitions than the special game won in the normal game.

[8-10. Ceiling setting example 8]

In setting example 8, attention is focused on the average acquired number VA4 that is the maximum among the special games BB, RB, and ART as the first special game lottery.
Specifically, when the distribution table shown in FIG. 17A is used in the ART distribution lottery in the first special game lottery, the expected value of the average number of acquired BB, RB, and ART is 315, 98, Since it is 147.4, VA4 is 315, which is the average number of BB acquired.
For example, in the second special game lottery, an ART distribution table shown in FIG. 25A is used. In this case, as shown in FIG. 25B, the average set number of ARTs executed by the second special game lottery is 7.0 sets, and the average acquired number is 308 (<315).

As a result, the game value that can be acquired on average by special games triggered by the ceiling is acquired on average by special games that can expect the highest average number of special games BB, RB, and ART won in normal games. It is possible to prevent the ceiling from becoming an opportunity to acquire an excessive gaming value because the gaming value is suppressed more than possible.

[8-11. Ceiling setting example 9]

Next, setting example 9 using another example in the ART sorting lottery will be described.
In the above setting examples 1 to 8, the ART distribution table storing the number of ART sets and the distribution probability is used.
In setting example 9, attention is focused on a value VA1 obtained by simply averaging the average number of acquired BBs, RBs, and ARTs using a sorting table in which the ART continuation rate and the lottery probability are stored.
Here, the ART continuation rate indicates the probability that the next one set of special games will be executed when the special game for one set of ART is digested. That is, if the continuation rate is 90%, the next set of ARTs is executed with a probability of 90%.
The lottery (continuous lottery) as to whether or not to continue ART is executed at a predetermined timing (for example, end timing or start timing for each set of ART or timing during ART game). The
In order to distinguish the continuation rate distribution lottery from the distribution lottery of the number of sets so far, the continuation rate distribution lottery is used, and the table used for the lottery is a continuation rate distribution table.

For example, in the first special game lottery, the ART continuation rate distribution lottery shown in FIG. 26A is executed. At this time, the average number of BB, RB, and ART acquired in the first special game lottery is 315, 98, and about 132.9, respectively. The average value VA1 of these is about 181.0 sheets.
On the other hand, in the second special game lottery, when the ART continuation rate distribution lottery shown in FIG. 26B is executed, the average number of ART sets executed by the second special game lottery is about 4 as shown in FIG. 26C. .04 sets, and the average number obtained is about 177.8 (<181.0).

  In setting examples 2 to 8, a continuation rate distribution lottery using a continuation rate distribution table may be performed instead of the distribution lottery. In that case, in each example, the continuation rate distribution table is set so as to satisfy the respective conditions (in the example of setting example 2, the expected value of the average number of ARTs acquired with the ceiling as an opportunity is less than VA2). It only has to be done.

Moreover, you may set the maximum continuation number with a continuation rate. For example, the maximum continuation number may be set to 15 or the like. In this case, the 15th continuous lottery is not performed (or the defeat is confirmed) even if the continuous lottery of ART is continuously won.
Thereby, it can prevent becoming an opportunity to acquire an excessive medal. Further, the maximum continuation number of ART in the second special game lottery may be set to a value smaller than the maximum continuation number of ART in the first special game lottery. Thereby, it is possible to provide a gaming machine whose ceiling is not an opportunity to acquire an excessive gaming value.

[8-12. Ceiling setting example 10]

In the setting example 1 to setting example 9 described above, an example focusing on the acquired number of sheets (average acquired number of sheets, maximum / minimum average acquired number of sheets, etc.) is shown, but in setting example 10, an example focusing on the net increased number of sheets is shown. explain.
As an example corresponding to setting example 1, setting example 10 focuses on a value VA10 obtained by simply averaging the average net increase numbers of BB, RB, and ART. At this time, in the first special game lottery, a distribution lottery using the distribution table of FIG. 17A is performed, and in the second special game lottery, a distribution lottery using the distribution table of FIG. 27A is performed.
The average net increase numbers of the special games BB, RB, and ART executed by the first special game lottery are 294, 84, and 67 as shown in FIG. 17B. The average value VA10 of these is (294 + 84 + 67) /3=148.3 sheets.

On the other hand, as shown in FIG. 27B, the expected value of the average net increase in ART executed by the second special game lottery is 20 × 0.05 + 40 × 0.05 + 60 × 0.05 + 100 × 0.25 + 140 × 0.3 + 200. × 0.3 = 133 (<148.3).
Thereby, it is possible to provide a gaming machine whose ceiling is not an opportunity to acquire an excessive gaming value.

In setting examples 2 to 9, attention may be paid to the net increase in number instead of the acquired number. In that case, in each example, so as to satisfy the respective conditions, that is, in the example of setting example 2, the expected value of the average net increase in ART in the second special game lottery is the special value in the first special game lottery. The distribution table (or continuation rate distribution table) may be set so that the value is smaller than the average net increase number including the winning probability of the game.

<9. Second Embodiment>
[9-1. Game types and ceilings]

Here, differences from the first embodiment will be mainly described, and portions not mentioned are the same as those in the first embodiment, and are not described here.

The gaming state of the slot machine includes a normal gaming state and a special gaming state that is more advantageous than the normal gaming state. As advantageous special game states, BB, RB, and ART will be described as examples.
In the second embodiment, BB, RB, and ART are drawn at a predetermined timing in the normal gaming state. In addition, the normal gaming state includes two types of states (hereinafter referred to as a first normal gaming state and a second normal gaming state) in which a lottery for transitioning to a special gaming state (hereinafter referred to as a special gaming lottery) is different. Description) is provided. Regarding BB and RB, the lottery probability in the first normal gaming state and the second normal gaming state is constant. Regarding the ART, the lottery related to the ART (hereinafter referred to as a special gaming state lottery) is different between the first normal gaming state and the second normal gaming state.

Examples of different lottery aspects related to ART include, for example, different lottery tables used for ART lottery, examples of different effects performed during lottery related to ART, and winning when ART is won. An example is the number of medals with different numbers.
Hereinafter, an example will be described in which the lottery table used for the ART lottery is different between the first normal gaming state and the second normal gaming state.

The special game lottery (BB, RB, ART) in the first normal game state is designated as a highly anticipated special game lottery (first special game lottery), and the special game lottery (BB, RB, ART) in the second normal game state. Is the low-expected special game lottery, and the special game lottery when the ceiling is reached is the special game lottery when the ceiling is reached (second special game lottery).
Also, a special game (BB, RB, ART) that is executed when a high-expected special game lottery is won is a special that is executed when a high-expected special game (first special game) or a low-expected special game lottery is won. A game (BB, RB, ART) is a low-expected special game, and a special game (ART) executed by a special game lottery when reaching the ceiling is a ceiling special game (second special game).

A specific example will be described with reference to FIG.
As in the first embodiment, the number of ceiling games (ceiling value) is 1000, and in addition, 700 is set as another count number.
When the count is from 0 to 700, the second normal gaming state is set, and from 700 to 1000 is the first normal gaming state. When the count reaches 1000, a special game lottery is executed when reaching the ceiling. In the special game lottery on the ceiling, unless otherwise specified, an example is used in which an ART distribution table (or continuation rate distribution table) in the low-expected special game lottery is used.

As shown in FIG. 28, the low-expected special game lottery is won in the 142nd game after the second normal game state is started, and BB as a special game is started. When the special game (BB) ends, the count of the number of games is reset to 0, and the state transitions to the second normal game state again. When the count value of the number of games reaches 700 without winning the special game lottery, the second normal game state is changed to the first normal game state, and the special game lottery is also performed as a highly anticipated special game lottery.
Thereafter, when the count value of the number of games reaches 1000 without reaching the first special game lottery and reaches the number of ceiling games (ceiling value), a distribution lottery using an ART distribution table executed by the low-expected special game lottery is executed. The ART as a special game is started in response to the lottery. In ART, for example, 10 games are set as one set, and one or a plurality of sets are continuously executed. In the example shown in FIG. 28, two sets are executed across the normal gaming state of seven games.

The second embodiment is an example in which the first normal gaming state is provided as a predetermined period immediately before the count reaches a predetermined value (ceiling value), but when the ceiling value is 1000, the predetermined period is Is less than 1000 (1 to 999) and is not included when the predetermined period is 1000. That is, the second embodiment is an example in which at least one game exists in the second normal gaming state.

[9-2. About the gaming value of high-expected special games and low-expected special games]

The relationship between the game value of the high-expected special game and the low-expected special game will be described.
In the high expectation special game lottery executed in the first normal game state, a lottery of BB (first type special game), RB, and ART (second type special game) as a high expectation special game is performed.
On the other hand, in the low expectation special game lottery executed in the second normal game state, a lottery of BB, RB, and ART as the low expectation special game is performed.
The basic game values of BB, RB, and ART are as shown in FIG. 16 when the ART is regarded as one set, and there is no difference between the high-expected special game and the low-expected special game.
The game values that take into account the results of the distribution lottery (or continuation rate distribution lottery) executed in the high-expected special game and the low-expected special game are also different. Further, the ART executed by the high-expected special game lottery has a higher expected value of the game value than the ART executed by the low-expected special game lottery.
An example of a specific distribution table is shown in the setting example of each ceiling shown below.

[9-3. Ceiling setting example 11]

In setting example 11, attention is paid to a value VA1 obtained by simply averaging the average number of obtained BB, RB, and ART.
The distribution table of ART in the high-expected special game lottery is as shown in FIG. 17A, and the average set number, average acquisition number and average net increase number executed by this are as shown in FIG. 17B. 3.35 sets, 147.4 sheets, 67 sheets.
On the other hand, FIG. 29A shows an ART distribution table in the low-expected special game. The average number of ART sets, the average number of acquired sheets, and the average net increase based on this distribution table are 2.75, 121, and 55, respectively, as shown in FIG. 29B.
As described above, in the special game lottery when reaching the ceiling, the distribution table of ART in the regular versus special game lottery is used. That is, the sorting table of FIG. 29A is used.

VA1 calculated from the average number of acquired BB, RB, and ART in the highly anticipated special game lottery is 186.8. The ART executed in the special game lottery at the time of reaching the ceiling is an average of 2.75 sets, and the average obtained number is expected to be 121 (<186.8) (see FIG. 29C).
Thereby, the game value that can be obtained on average by a special game (ART as the second special game) triggered by the ceiling is obtained by BB, RB, ART as the first special game won in the first normal game state. It is possible to prevent the ceiling from being an opportunity to acquire an excessive gaming value because the gaming value that can be performed is suppressed from a value simply averaged (VA1).

In addition, in setting example 11, the average game value that can be acquired by the special game at the time of reaching the ceiling is reduced as compared with the average value VA2 of the average number of acquisitions including the appearance rates of BB, RB, and ART. (See FIG. 29D).
Specifically, VA2 is about 173.3 (calculated by the same formula as setting example 2), which is larger than the average game value (121) that can be obtained by the special game when reaching the ceiling.
Also by this, the game value that can be obtained on average by the special game (ART as the second special game) triggered by the ceiling is the BB, RB, ART as the first special game won in the first normal game state. It is possible to prevent the ceiling from becoming an opportunity to acquire an excessive gaming value because the average acquired number (VA2) calculated from the average acquired number and appearance rate is suppressed.

[9-4. Ceiling setting example 12]

In the setting example 12, attention is paid to the average acquired number of sheets VA3 that is the minimum of the average acquired number of sheets of BB, RB, and ART.
The distribution table of ART in the high expectation special game lottery in the setting example 12 uses the distribution table shown in FIG. 17A. Therefore, the minimum average acquired number of sheets VA3 is 98, which is the average acquired number of RBs, as shown in FIG. 17B.
Further, the distribution table of ART in the low-expected special game lottery and the ceiling special game lottery uses the distribution table shown in FIG. 20A.
In this case, the expected value of the average number of acquired special games when reaching the ceiling is 88, which is less than VA3 (= 98) (see FIG. 20B).
As in setting example 3, paying attention to the minimum average acquired number VA3 ′, a special table lottery distribution table when reaching the ceiling may be set.

[9-5. Ceiling setting example 13]

In setting example 13, paying attention to the average value VA2 of the average acquired number of sheets including the appearance rate of each of BB, RB, and ART, the ceiling of the ceiling is set so that the average acquired number of ARTs executed with the ceiling becomes smaller than VA2. Although the ART distribution lottery is executed, an example will be described in which the maximum number of sets to be distributed is higher in the ART distribution lottery on the ceiling than the ART distribution lottery in the high-expected special game lottery.
Specifically, the distribution table shown in FIG. 17A is used as the distribution table for ART in the high-expected special game lottery. Further, as the distribution table of ART in the low-expected special game lottery and the special game lottery at the time of reaching the ceiling, the distribution table shown in FIG. 22A is used.

As a result, the maximum number of sets that can be distributed is 10 in the highly anticipated special game lottery, but 20 in the special game lottery when reaching the ceiling. That is, the maximum average number of ARTs executed by the special game lottery when reaching the ceiling is 880, which is larger than BB (315), RB (98), or ART (440 in 10 sets).
However, the expected value (143) of the average number of acquired ARTs executed by the special game lottery when reaching the ceiling is smaller than the average value VA2 (173.3) of the average acquired number including the appearance rate (FIG. 22B).
As in setting example 4, instead of paying attention to VA2, attention may be paid to VA1, VA3, and VA3 ′.

[9-6. Ceiling setting example 14]

In setting example 14, paying attention to the average value VA2 of the average acquired number of sheets taking into account the appearance rates of BB, RB, and ART in the high-expected special game, the average acquired number of ARTs executed with the ceiling as a trigger is larger than VA2 However, an example in which the maximum number of sets that can be distributed is reduced will be described.
In the setting example 14, a distribution table different from the ART distribution table in the low-expected special game lottery is used in the ART distribution lottery triggered by the ceiling.
Specifically, the distribution table of FIG. 23A is used in the ART distribution lottery of the highly anticipated special game lottery. Further, in the distribution lottery of ART in the low-expected special game lottery, the distribution table of FIG. 29A is used. Further, in the special game lottery when reaching the ceiling, the distribution table of FIG. 23B is used.

In this case, VA2 of the high-expected special game is 175.9, and the maximum average acquired number is 1320 when winning 30 sets of ART. In addition, the average number of special games acquired when reaching the ceiling is 220 (> 175.9), and the maximum average number is 880 (<1320) when 20 sets are won.
Therefore, an ART with a ceiling as an opportunity is expected to have a higher average number of winnings than the highly anticipated special game won in the high-expected special game lottery, but the maximum average winning number is reduced, so the ceiling is excessive. It is possible to prevent a game value acquisition opportunity (30 sets of ART in setting example 14).
Similar to setting example 5, instead of paying attention to VA2, attention may be paid to VA1, VA3, and VA3 ′.

[9-7. Ceiling setting example 15]

In setting example 15, attention is paid to the ART volume zone as the representative performance of ART.
In setting example 15, a distribution table different from the ART distribution table in the low-expected special game lottery is used in the ART distribution lottery triggered by the ceiling.
Specifically, the distribution table of FIG. 24A is used in the ART distribution lottery of the highly anticipated special game lottery. Further, in the distribution lottery of ART in the low-expected special game lottery, the distribution table of FIG. 29A is used. Furthermore, in the special game lottery when reaching the ceiling, the distribution table of FIG. 24B is used.

When paying attention to the volume zone of ART, the volume zone of the set number of the ART distribution lottery in the highly anticipated special game lottery is 3 sets, and the volume zone of the number of the ART distribution lottery set in the special game lottery when reaching the ceiling is 2 sets. .
Therefore, the VA2 of the highly anticipated special game is 167, and the average number of acquired special games when reaching the ceiling is 88 (<167).
As in setting example 6, instead of paying attention to VA2, attention may be paid to VA1, VA3, and VA3 ′.

[9-8. Ceiling setting example 16]

In setting example 16, an example of using the ART distribution table (FIG. 17A) in the highly anticipated special game lottery in the ART distribution lottery in the special game lottery when reaching the ceiling will be described.
At this time, the average value VA2 of the average acquired number of sheets including the appearance rates of BB, RB, and ART in the high-expected special game is about 173.3. Also, the expected value of the average number of acquired special games when reaching the ceiling is 147.4.
That is, even if the same sorting table is used, the expected value of the average number of acquired games is reduced in the special game triggered by the ceiling, compared to the special game won in the normal game.

[9-9. Ceiling setting example 17]

In the setting example 17, attention is paid to the average acquired number VA4 of the maximum among the special games BB, RB, and ART as the high-expected special game lottery.
In setting example 17, a distribution table different from the ART distribution table in the low-expected special game lottery is used in the ART distribution lottery triggered by the ceiling.
Specifically, the distribution table of FIG. 17A is used in the ART distribution lottery of the highly anticipated special game lottery. Further, in the distribution lottery of ART in the low-expected special game lottery, the distribution table of FIG. 29A is used. Furthermore, in the special game lottery when reaching the ceiling, the distribution table of FIG. 25A is used.
In this case, VA4 in the highly anticipated special game is 315, which is the average number of BB acquired. Further, the average number of ARTs executed by the special game lottery at the time of reaching the ceiling is 7.0 sets, and the average number obtained is 308 (<315).

As a result, the game value that can be obtained on average by special games triggered by the ceiling is averaged by the special game that can expect the highest average number of winning games among the special games BB, RB, and ART won in the highly anticipated special game lottery. Therefore, it is possible to prevent the ceiling from being an opportunity for acquiring excessive gaming value.

[9-10. Ceiling setting example 18]

In the setting examples 11 to 17, the ART distribution table storing the number of ART sets and the distribution probability is used. However, in the setting example 18, the continuation ratio distribution table storing the ART continuation rate and the lottery probability. Is used. Note that a value VA1 obtained by simply averaging the average number of obtained BB, RB and ART.
In setting example 18, the distribution table of FIG. 26A is used in the ART continuation rate distribution lottery of the high-expected special game lottery. Further, in the ART continuation rate distribution lottery of the low expectation special game lottery, the distribution table of FIG. 30 is used. Furthermore, in the ART continuation rate distribution lottery in the special game lottery when reaching the ceiling, the distribution table of FIG. 26B is used.
In this case, VA1 in the high-expected special game is about 181.0. In addition, the average number of ARTs executed by the special game lottery when reaching the ceiling is about 4.04 sets, and the average number obtained is about 177.8 (<181.0).

In setting example 11 to setting example 17, a continuation rate distribution lottery using a continuation rate distribution table may be performed instead of the distribution lottery. In that case, in each example, the continuation rate distribution table may be set so as to satisfy the respective conditions.

[9-11. Ceiling setting example 19]

In the setting example 11 to the setting example 18, an example in which attention is paid to the acquired number of sheets (average acquired number of sheets, maximum / minimum average acquired number of sheets, etc.) has been shown. .
As an example corresponding to setting example 11, setting example 19 focuses on a value VA10 obtained by simply averaging the average net increase numbers of BB, RB, and ART. At this time, in the highly anticipated special game lottery, a distribution lottery using the distribution table in FIG. 17A is performed, and in the special game lottery when reaching the ceiling, a distribution lottery using the distribution table in FIG. 29A is performed.
The average net increase numbers of the first special games BB, RB, and ART executed in the highly anticipated special game lottery are 294, 84, and 67 as shown in FIG. 17B. The average value VA10 of these is (294 + 84 + 67) /3=148.3 sheets.

On the other hand, the expected value of the average net increase in ART executed by the special game lottery when reaching the ceiling is 20 × 0.3 + 40 × 0.4 + 60 × 0.1 + 100 × 0.1 + 140 × 0.05 + 200 as shown in FIG. 29B. × 0.05 = 55 (<148.3).
Thereby, it is possible to provide a gaming machine whose ceiling is not an opportunity to acquire an excessive gaming value.

In setting examples 11 to 18, attention may be paid to the net increase in number instead of the acquired number. In that case, in each example, a distribution table (or a continuation rate distribution table) may be set so as to satisfy each condition.

<10. Modification>

In the second embodiment, the example in which the first normal gaming state and the second normal gaming state are provided as the normal gaming state has been described. However, three or more normal gaming states may be provided.
In the second embodiment, the example in which the transition from the first normal gaming state to the second normal gaming state is performed with a specific number of games has been described. In addition, the transition is also performed by a specific small role or the like. Also good. Specifically, when the ceiling value is 1000, the count number of transition from the first normal gaming state to the second normal gaming state is set to 900, and a specific small role is established a predetermined number of times, Even the number of games may be changed to the second normal gaming state.

  In each of the above-described embodiments, the distribution table, the continuation rate distribution table, or the lottery probability of each special gaming state (BB, RB, ART) is shown. It shows an example of one set value (one to which any one of 1 to 6 is set) in the machine. The table or the lottery probability may be changed for each different set value to give a difference to the game value in the specific game state.

  In each of the above-described embodiments, the example in which the initial setting value of the ceiling value after resetting the count to 0 has been described as a specific value (for example, 1000). However, the initial setting value of the ceiling value after reset differs for each reset. It may be a value. For example, a ceiling value lottery may be performed when resetting the count to 0, and one of a plurality of ceiling value candidates may be selected.

In the second embodiment, the example in which the first normal gaming state and the second normal gaming state are provided has been described. In this case, a difference may be provided in the performance mode in each normal gaming state so that the player can easily grasp which state is the first normal gaming state or the second normal gaming state.
Specifically, an effect that is executed only in the first normal gaming state is provided, or the appearance probability of a specific effect is changed between the first normal gaming state and the second normal gaming state.

In the second embodiment, an example in which the first type special game is BB has been described, but another special game such as RB may be the first type special game.

<11. Summary>

In the rotary type gaming machine described in the first embodiment, the rotation reels 4a, 4b, 4c as a plurality of rotary cylinders on which a plurality of symbols are displayed, and start control for starting rotation of the rotary cylinder Means (CPU 80a of the main control board 40), stop control means (CPU 80a of the main control board 40) for stopping the rotation of the rotating drum, and role lottery means (main control board) for performing the lottery when the predetermined condition is satisfied 40 CPUs 80a), counting means for counting objects (number of games, specific small role, number of executions of specific effects, etc.), and the first special game lottery is executed until the count reaches a predetermined value. Special game control means (the CPU 80a of the main control board 40 or the CPU of the effect control board 42) that executes the second special game when the number reaches a predetermined value, and is an average in the first special game Acquisition game value is greater than the average win game value in the second special game.
Further, in the rotating type gaming machine described in the first embodiment, the rotating reels 4a, 4b, and 4c serving as a plurality of rotating cylinders on which a plurality of symbols are displayed, and the start timing of rotation of the rotating cylinder Start means (start lever 17), stop means (stop buttons 18a, 18b, 18c) that trigger rotation stop of the rotating cylinder, and rotation control means (main control) that controls start / stop of the rotating cylinder CPU 80a of the board 40), a role lottery means (CPU 80a of the main control board 40) for performing a lottery when a predetermined condition is established, and count objects (number of games, specific small roles, number of executions of specific effects, etc.) Counting means for counting and special game control means (main control board) for executing the lottery of the first special game until the count number reaches a predetermined value and executing the second special game when the count number reaches the predetermined value 40 CPUs 80a Or comprises a CPU) of the performance control board 42, and the average acquisition game value in the first special game is greater than the average win game value in the second special game.
Thereby, for example, when the lottery of the first special game is executed in the normal game state and the second special game is executed on the ceiling, the special game in the normal game state has more acquired game value than the ceiling. Thus, it is possible to provide a swivel-type gaming machine that can prevent the ceiling from being an opportunity to acquire an excessive gaming value.

Further, at least two types of first type special games (for example, BB) and second type special games (for example, ART) are provided as the first special games.
Thereby, even in a rotating game machine provided with a plurality of types of special games, for example, when the first special game lottery is executed in the normal game state and the second special game is executed on the ceiling, Since the special game in the normal game state has more acquired game value than the ceiling, it is possible to provide a revolving game machine that can prevent the ceiling from being an opportunity to acquire an excessive game value.

Furthermore, the average acquired game value in the second special game is smaller than both the average acquired game value of the first type special game and the average acquired game value of the second type special game.
Thereby, for example, when the lottery of the first special game is executed in the normal game state and the second special game is executed on the ceiling, the acquired game value is less than any special game in the normal game state. Thus, it is possible to provide a swivel-type gaming machine that can further prevent the ceiling from becoming an opportunity to acquire an excessive gaming value.

Furthermore, the average acquired game value in the second special game is smaller than the average value of the average acquired game value in the first type special game and the second type special game. When a special game lottery is executed and a second special game is executed on the ceiling, the ceiling will provide an opportunity to acquire an excessive game value while securing a certain amount of special game value on the ceiling. It is possible to provide a swivel-type gaming machine that can be more prevented.

In addition, the average acquired game value in the second special game is less than the maximum value of the average acquired game value of the first type special game and the second type special game. When the first special game lottery is executed and the second special game is executed on the ceiling, the special game with the maximum average acquired game value is one of the first special games. It is possible to provide a swivel type gaming machine that can prevent an excessive game value from being obtained.

In the rotary type gaming machine described in the second embodiment, the rotation reels 4a, 4b, and 4c as a plurality of rotary cylinders on which a plurality of symbols are displayed, and start control for starting the rotation of the rotary cylinder Means (CPU 80a of the main control board 40), stop control means (CPU 80a of the main control board 40) for stopping the rotation of the rotating drum, and role lottery means (main control board) for performing the lottery when the predetermined condition is satisfied 40 CPUs 80a), counting means for counting objects (the number of games, specific small role, number of executions of specific effects, etc., and the number of games in each embodiment), and the count number is a predetermined value (1000 games) The special game control means (CPU 80a of the main control board 40) executes the second special game when the value reaches the predetermined value, and executes the lottery of the first special game in a predetermined period (300 games) immediately before reaching the predetermined value. Or comprises a CPU) of the performance control board 42, and the average acquisition game value in the first special game is greater than the average win game value in the second special game.
Further, in the rotating type gaming machine described in the second embodiment, rotating reels 4a, 4b, and 4c as a plurality of rotating cylinders on which a plurality of symbols are displayed, and a start trigger for rotation of the rotating cylinder Start means (start lever 17), stop means (stop buttons 18a, 18b, 18c) that trigger rotation stop of the rotating cylinder, and rotation control means (main control) that controls start / stop of the rotating cylinder The CPU 80a of the board 40), the role lottery means (the CPU 80a of the main control board 40) for performing the lottery when the predetermined condition is satisfied, and the count target (the number of games, the specific small role, the number of executions of the specific effect, etc.) In each embodiment, the counting means for counting the number of games), the second special game is executed when the count number reaches a predetermined value (1000 games), and a predetermined period (300 games) immediately before reaching the predetermined value )smell Special game control means (the CPU 80a of the main control board 40 or the CPU of the effect control board 42) for executing the lottery of the first special game, and the average acquired game value in the first special game is the second More than the average value of games played in special games.
Thus, for example, when the first special game lottery is executed in the first normal game state immediately before the ceiling and the second special game is executed on the ceiling, the special game in the first normal game state rather than the ceiling However, since the acquired gaming value is large, it is possible to provide a swivel type gaming machine capable of preventing the ceiling from being an opportunity to acquire an excessive gaming value.

Also, at least two types of first type special games and second type special games are provided as the first special games.
As a result, even in a swivel type gaming machine provided with a plurality of types of special games, for example, the first special game lottery is executed in the first normal game state immediately before the ceiling, and the second special game is executed on the ceiling. In this case, the special game in the first normal gaming state has a higher gaming value than the ceiling, so that a revolving gaming machine that can prevent the ceiling from triggering excessive gaming value is provided. can do.

Furthermore, the average acquired game value in the second special game is smaller than both the average acquired game value of the first type special game and the average acquired game value of the second type special game.
Thereby, for example, when the first special game lottery is executed in the first normal game state immediately before the ceiling and the second special game is executed on the ceiling, the ceiling is more than any special game in the first normal game state. However, since the acquired gaming value is small, it is possible to provide a swivel type gaming machine that can prevent the ceiling from being an opportunity to acquire an excessive gaming value.

Furthermore, the average acquired game value in the second special game is less than the average value of the average acquired game value of the first type special game and the second type special game.
Thereby, for example, when the first special game lottery is executed in the first normal game state immediately before the ceiling and the second special game is executed on the ceiling, the acquired game value of the special game on the ceiling is secured to some extent. Thus, it is possible to provide a swivel-type gaming machine that can further prevent the ceiling from becoming an opportunity to acquire an excessive gaming value.

In addition, the average acquired game value in the second special game is smaller than the maximum value among the average acquired game values of the first type special game and the second type special game.
Thereby, for example, when the first special game lottery is executed in the first normal game state immediately before the ceiling and the second special game is executed on the ceiling, the special game having the maximum average acquired game value is the first special game. Since it is regarded as one of the special games, it is possible to provide a swivel type gaming machine capable of preventing the ceiling from being an opportunity to acquire an excessive gaming value.

  Moreover, although the example in which the present invention is applied to a slot machine has been described above, the present invention can be widely and suitably applied to a spinning-type game machine including a plurality of spinning cylinders on which a plurality of symbols are displayed.
