Next, the operation and effect of the gaming machine according to the present embodiment will be described.

Since the gaming machine 10 is configured as described above, it operates as follows. First, when the starting winning ball sensor 33 outputs a winning detection signal at the starting winning port 23, the main control circuit 50 executes a jackpot determination, and the symbol display device 40 displays the change of the special symbols N1 to N3 and other symbols. Various control commands related to game control are determined. Next, based on the determination of the main control circuit 50, the display control circuit 60 generates data for the variable display and the effect display of the special symbols N1 to N3 on the symbol display device 40. Next, the special symbols N1 to N4 based on the variable display generated by the display control circuit 60.
The stop mode of N3 is a specific prize mode, and the main control circuit 50
If the big hit determination result is "big hit", the opening / closing plate 26a of the big winning port 26 is opened and the game ball wins with a high probability, and the big hit state is much more advantageous to the player than the normal game. Become.

More specifically, the main control circuit 50 performs a "main game control process" shown in FIG. 6, an "interrupt process" shown in FIG. 7, and a "special symbol game control process" shown in FIG. Be executed. (Main game control processing and interrupt processing)

In the "main game control process" shown in FIG.
First, an interrupt permission flag is set (step S1),
Next, a process of updating the lost symbol determination random number counter 53b and the reach operation determination random number counter 53e is performed (step S2). Next, it is determined whether or not a command is being transmitted from the main control circuit 50 to each of the control circuits such as the display control circuit 60, the sound control circuit 92, and the prize ball control circuit 94 (step S3). If it is in the middle, the process returns to step S1. On the other hand, if the command is not being sent, a command for the error check process is generated (step S4), and the error check process is executed based on the generated command (step S5).

Next, it is determined whether or not an error has occurred (step S6). If an error has occurred, the process returns to step S1. If no error has occurred, a "special symbol game control process" described later is executed. Later (step S7), the process returns to step S1.

The "interrupt processing" shown in FIG. 7 is performed periodically (for example, every 3 msec) on condition that the interrupt permission flag is set in step S1 in the above-mentioned "main game control processing" or in step S20 described later. ) Is executed. In the "interrupt processing", first, in order to temporarily save the current program, the data of each register is saved in a predetermined area of the main RAM 52 (step S1).
0), the big hit determination random number counter 53a, the big hit symbol determination random number counter 53c, and the variation pattern number determination random number counter 53d are updated (step S1).
1). Next, various timers are initialized (step S1).
2), input processing of various sensor information and the like is executed (step S13).

By the various input processes, for example, a change command of a normal symbol is generated in accordance with the detection signal of the passing ball sensor 37, and a prize ball payout command is generated in accordance with the detection signal of the winning ball sensor 34. In accordance with the detection signal of the starting winning ball sensor 33, generation of a winning ball payout command and special symbol N1
The number of wins stored as a change start command for N3 (for example, up to 4 in accordance with the number of start winning balls, the special symbols N1 to N
3 is subtracted each time the variable game is executed).

Next, in step S14, a normal symbol changing process is performed by the normal symbol display LEDs 35a and 35b. In this process, after a winning determination is made on the variation of the ordinary symbol, the normal symbol display LEDs 35a and 35b are stopped based on the determination result (for example, which of the two colors of the ordinary symbol displaying LEDs 35a and 35b is stopped). Is controlled).

Next, the control of the illuminated parts such as the decoration lamps 29A and 29B is executed (step S15), and the payout processing, that is, the prize ball (game game) according to the prize ball payout command output in the processing of step S13 The processing of paying out the ball) is executed (step S16).

Next, predetermined error processing is performed on error signals from various devices of the gaming machine 10 (step S17), and various commands stored in the main RAM 52 are displayed by the display control circuit 60 and the sound control unit. After performing transmission data output processing for transmission to various control circuits such as the control circuit 92 (step S18), the data of each register saved in a predetermined area of the main RAM 52 in step S10 is restored (step S19). Then, an interrupt permission flag is set to recover the interrupted / evacuated program (step S20), and the current "interrupt processing" is performed.
To end. The various commands stored in the main RAM 52 include commands generated in a “special symbol game control process” described later. (Control of special symbol game on the main control circuit side)

"Special symbol game control processing" shown in FIG.
Is repeatedly executed in the “main game control process” as described above. In the “special symbol game control process”, first, it is determined whether or not there is a start winning (step S2).
1) If there is no start winning, a demo screen process is executed (step S22), and the process returns to the step S21. In the demonstration screen processing, for example, whether or not to switch the title demonstration screen by the timer function of the main control circuit 50 is determined based on whether or not a predetermined time (for example, 50 seconds) has elapsed since the last fluctuation stop. The title demonstration screen is, for example, a demonstration display for giving an overview of the gaming machine 10 and for introducing characters appearing in the effect display.

On the other hand, if it is determined in step S21 that there is a winning start, step S11 of "interrupt processing" is executed.
The count value of the big hit judgment random number counter 53a updated in the above is read as a big hit judgment random number,
Referring to the jackpot determination table stored in 51,
It is determined whether it is a “big hit” (step S2
3). In this big hit determination table, for example, if the big hit determination random number is 7, it is “big hit”, and the big hit determination random number is another number in the update range, that is, 0 to 6 or 8 to 3
In the case of 34, a determination item of "losing" is set.

The result of the determination in step S23 is "big hit"
If so, the main ROM 51
With reference to the effect group selection table stored in step S11, the count value of the variation pattern number determining random number counter 53d updated in step S11 is read, and a group of effect images to be displayed is selected (step S24).

In this effect group selection process, effect patterns such as a normal effect and a reach effect described later are divided into a plurality of groups, and in each effect such as a normal effect and a reach effect, one of the effect groups is determined. Is to be selected. In addition, a variation pattern number is assigned to each of the effect groups, and a variation time, a fixed time, a reach appearance rate, a jackpot reliability (a jackpot occurrence probability), and the like are set. Then, since the determination result in step S23 is "big hit", an effect group corresponding to any of the variation pattern number ranges of "big hit" is selected.

When a group of effect images to be displayed is selected in step S24, the count value of the big hit symbol determining random number counter 53c updated in step S11 of the above-described "interrupt processing" is changed to a big hit stopping mode selection random number. With reference to the jackpot stop mode selection table stored in the main ROM 51, one of a plurality of predetermined jackpot stop modes is selected and determined as a big hit symbol (step S25). The big hit symbol determined in step S25 is in a stop mode determined after stopping the fluctuation of the special symbols N1 to N3. The big hit stop mode selection table is for selecting a stop mode in which three special symbols of the same mode such as “7, 7, 7” are arranged according to a random number value. In addition, it includes a stop mode in which marks other than numerals are combined, such as an image of a specific character, an image representing flowers and fruits, and the like. The types of special symbols in the present embodiment are, for example, 12 types. The image data for displaying the special symbol of the big hit stop mode on the display screen 41 is stored in the image ROM 64 of the display control circuit 60. In the above-described jackpot stop mode selection table, a code number for identifying each jackpot stop mode is assigned, and the code number of the selected jackpot stop mode is determined by a first stop symbol number designation command and a second stop symbol number command described later. The stop symbol number designation command and the third stop symbol number designation command are respectively set.

If the determination in step S23 is "losing", the count value of the reach operation determination random number counter 53e updated in step S2 of the "main game control process" is read as a reach determination random number.
The presence / absence of reach (whether or not a reach state is to be generated) is determined with reference to the reach determination table stored in. Here, in the reach determination table, for example, when the reach determination random number is “0”, it is determined that “reach is present”, and when the reach determination random number is “1 to 9”, it is determined that “reach is absent”. As described above, the random number value and the judgment item are associated with each other.

Then, based on the determination result of the presence or absence of the reach and the determination result in step S23, step S24 is performed.
In the same manner as described above, with reference to the effect group selection table stored in the main ROM 51, the count value of the variation pattern number determination random number counter 53d updated in step S11 is read, and a group of effect images to be displayed is selected. (Step S26). Note that if the determination in step S23 is “losing” and the determination result of the presence or absence of the reach is “reach present”, the effect group corresponding to any of the variation pattern number ranges of “losing” and “reach present” Is selected, if the determination in step S23 is "losing" and the determination result of the presence or absence of the reach is "no reach",
The effect group corresponding to any of the variation pattern number ranges of “losing” and “no reach” is selected.

When the group of effect images to be displayed is selected in step S26, it is determined whether the result of the determination of the presence or absence of the reach in step S26 is "reach available" or "reach not available" ( Step S27).

If the result of the determination in step S27 is "reach available", step S2 of the "main game control process"
The count values of the left symbol determining random number counter, the medium symbol determining random number counter, and the right symbol determining random number counter of the losing symbol determining random number counter 53b updated in the above are respectively referred to as "first stop symbol determining random number", ""1st stop symbol selection table", "2nd stop symbol selection table", read out as "2nd stop symbol determination random number" and "3rd stop symbol determination random number", and
With reference to the "3rd stop symbol selection table",
The special symbol constituting the fixed stop mode in the case of "losing" is determined (step S28). Note that the order of stopping the special symbols is arbitrary, but in the gaming machine 10, the order is left symbol-right symbol-medium symbol. Also, if the first stop symbol is a "first stop symbol", the second stop symbol is a "second stop symbol", and the third stop symbol is a "third stop symbol (final stop symbol)", "1st stop symbol" is "2nd stop symbol" from "1st stop symbol selection table".
From the "stop symbol selection table", the "third stop symbol" is selected from the "third stop symbol selection table".

In the determination process of the reach-losing stop symbol in step S28, the first stop symbol selection table is read from the first stop symbol selection table based on the read-out "first stop symbol determination random number".
A symbol to be displayed on the display screen 41 as a stop symbol (for example, a left symbol N1) is selected, and a special symbol in the same mode as the left stop symbol is set to a second stop symbol (for example, a right or middle symbol N3) so as to be in a reach state. Or N2). Further, based on the read “third stop symbol determining random number”,
A special symbol to be displayed as the third symbol is selected from the "stop symbol selection table". Here, since it is a determination of "losing", if the selected third stop symbol is in the same mode as the first and second stop symbols, a special symbol shifted by one frame is set as the third stop symbol.

On the other hand, if the result of determination in step S27 is "no reach", a left symbol determination random number counter of the lost symbol determination random number counter 53b updated in step S2 and a middle symbol determination Read the count values of the random number counter and the right symbol determination random number counter as first to third stop symbol selection random numbers, respectively.
With reference to the first to third stop symbol selection tables stored in the main ROM 51, a special symbol constituting a fixed stop mode in the case of "losing" is determined (step S2).
9). Here, first, the first stop symbol and the third stop symbol are selected based on the read “random number for first stop symbol selection” and “random number for third stop symbol selection”, and it is determined that there is no “reach”. Therefore, if the selected second stop symbol is the same symbol as the first stop symbol, the symbol shifted by one frame is selected as the second stop symbol.

Each of the first, second, and third stop symbol selection tables is assigned a code number for identifying each stop symbol, and the code number of each stop symbol selected in each table is assigned. First, second and third
Is set as the stop symbol number designation command.

When the effect groups and the special symbols N1 to N3 are determined to be stopped in the processing from step S23 to step S29, the display control circuit 60 is controlled so that the screen display according to the determined content is performed on the display screen 41. A display control command is generated, and the generated display control command is stored in the main RAM 52 (step S30). The display control command stored in the main RAM 52 is a transmission data output process (step S1) of the above-described “interrupt process”.
8) is transmitted to the display control circuit 60.

The display control commands here are, for example, an effect group designation command and first to third stop symbol number designation commands depending on the control contents. The effect group designation command includes information for specifying a jackpot determination result, the presence or absence of a reach, a reach effect, and the presence or absence of a development notice.

When the display control command is stored in the main RAM 52, the animation display time set for the selected effect group is set in the animation display time management timer, and counting is performed from the start of display. Then, when the animation display time management timer reaches a set value (for example, the remaining time t = 0), the determination command is stored in the main RAM 52. The fixed command is a control command for requesting a complete stop of the variable display of the special symbol, and is sent to the display control circuit 60 to control the variable display to be stopped. Note that the finalization command is also transmitted to the display control circuit 60 by the transmission data output process (step S18) of the above-described “interrupt process”.

Next, it is determined whether or not a "big hit" has occurred (step S31). If the result of the determination is "losing"("NO" in step S31), a special symbol game which is a counter for counting the number of times of hitting is performed. The counter is incremented by 1 (step S32), and the current "special symbol game control process" is terminated (step S33).

On the other hand, if the result of the determination in step S31 is "big hit"("YES" in step S31), the value of the special symbol game counter is reset to 0 (step S34), and the special game process is executed. Yes (Step S3
5). Here, in the special game processing, first, a command (hereinafter, referred to as a big hit notification sound output command) for requesting the output of a big hit notification sound (fan fare sound) from the speaker 93 or a special game for notifying the start of the special game state. A command for requesting display of the state start screen on the display screen 41 (hereinafter, referred to as a special game state start screen display command).
Is stored in the main RAM 52 to perform time management and the like relating to the special game state. Next, a predetermined determination process is performed according to whether or not the special winning opening 26 is in the opening operation, and after the round of the big hit game is continued, the display screen 41 of the special game state end screen for notifying the end of the special game state is made. Is stored in the main RAM 52 (hereinafter, referred to as a special game state end screen display command). The jackpot notification sound output command, the special game state start screen display command, and the special game state end screen display command correspond to the transmission data output processing (step S
18) is transmitted to the display control circuit 60.

When the special game processing is executed in step S35, the present "special symbol game control processing" is ended (step S33). (Display control by display control circuit)

In response to various control commands from the main control circuit 50 for performing the above-described control, the display control circuit 60 performs “main display control processing” shown in FIG. The “interrupt processing of main board STB input” shown in FIG. 10 and the “timer interrupt processing” shown in FIG. 11 are executed, and a plurality of “task control processing” shown in FIGS. 12 to 15 and “task control processing” shown in FIG. Interrupt processing for display output "is executed.

First, in the "main display control process" shown in FIG.
The initial setting process of the operation of the PU 63 is executed (step S51), and after the work RAM 62 is cleared (step S52), the initial setting process of the operation of the VDP 65 is executed (step S53). “Mother task processing” is started (step S5)
4). That is, when power is supplied to the display control circuit 60 when the power of the gaming machine 10 is turned on, it is checked whether an abnormality has occurred in the program ROM 61, the image ROM 64, and the like, and the operations of the sub MPU 63, the work RAM 62, and the VDP 65 are performed. Is initialized.

The "interrupt processing of main board STB input" shown in FIG.
robe) signal, and is executed. First, it is determined whether or not the loop in this processing is the second time (step S4).
1) If it is the second time, the current “interrupt processing of main board STB input” is ended. On the other hand, if it is not the second time, various control commands from the main control circuit 50 are received twice (step S42, step S43), and it is determined whether all the received commands are the same (step S44). If it is determined that the received commands are all the same, the received data is stored in the work RAM 62 (step S45), and the current “main board STB input interrupt processing” ends. On the other hand, if it is determined in step S44 that the received commands are not all the same, the process returns to step S41. That is,
After confirming that the received command has been reliably received, the memory storage processing is performed, and a standby state for waiting for the reception of the next control command is entered, thereby terminating the current “main board STB input interrupt processing”.

The "timer interrupt process" shown in FIG. 11 is an interrupt process that is performed, for example, every 2 msec. After discriminating the preceding and succeeding data of the received command, the data of the received command is used for the "mother task process" described later. A generation process for performing the conversion is performed (step S46), and a process such as interpretation of the received command is performed (step S47).

In the "mother task process" started in step S54, as shown in FIG.
After the initial setting process for screen display by P65 is performed (step S55), it is determined whether or not the fluctuation pattern has been designated by the main control circuit 50 (step S5).
6) If a fluctuation pattern is specified, a “variation pattern setting process” described later is executed (step S57), and a “director file animation control task” described later is started (step S58), and further “animation” described later is executed. The display task is started (step S59).

Next, a special symbol setting process is executed (step S61). In the special symbol setting process, it is determined whether or not a symbol to be stopped next is designated in the stop order of the first to third stop symbols, and if so, a setting process for the fluctuation of the symbol is performed. On the other hand, if it has not been specified, it is checked whether or not another stop symbol has been specified, or whether or not a variation pattern has been specified.

Next, it is determined whether or not all the left, right, and middle stop symbols have been designated and the symbols have been determined (step S6).
6) If it is determined, a symbol determination setting process for setting a determination flag to 1 is executed (step S67). If not determined, step S67 is not executed and the process proceeds to step S56 in a task control waiting state. It returns (step S68).
The processes in steps S56 to S59 are executed each time a change pattern is specified. In the “mother task process”, when the control command is confirmed to be received, the designation information of the received command is stored in the work RAM 62 of the display control circuit 60. The type of the received command here corresponds to the type of the display control command described above (effect group designation command, first to third stop symbol number designation command, confirmation command, and the like).

In the "variation pattern setting process" shown in FIG. 13, first, the decision flag is reset to zero (step S71), and then the variation pattern number determination random number counter 53
The change pattern information of the number corresponding to the random number extracted by d is set (step S72), the change control task is started (step S73), the change animation setting task is started (step S74), and the special symbol reel is further set. The processing task is started (Step S75). here,
If there is an effect group designation command as the variation pattern information, one animation sequence program is selected from the program ROM 61 based on this command and set in a predetermined area in the work RAM 62. Further, any one of the variation control task sequence programs is selected based on the read effect group designation command. Then, based on these programs, control processing relating to variable display of special symbols is executed, and control processing relating to animation display including effect images is executed.

In the above-described variable animation setting task (step S74), a sign image of occurrence of reach, an effect image after the reach, an effect image on the big hit screen, and the like are set. Animation data and characters to be displayed are sorted and grouped based on data such as a sorting table prepared in advance.
These images of the plurality of types of characters and items are used alone or in combination. When animation data is distributed, regardless of the presence or absence of signs or reach effects, animation setting processing that becomes a common variable display part is performed, and processing to wait for the completion of the `` director file animation control task processing '' described later Is done.

In the special symbol reel processing task (step S75), the display coordinate data of the special symbol is converted into screen coordinates on the display screen 41. Here, the display area 41a of each symbol on the display screen 41
The generation process of the symbol objects displayed on the display objects 41 to 41c is as follows.
Basically, the special symbol N1, N2, or N3 displayed in each of the display areas 41a to 41c is set as a symbol mode imitating a symbol row of a reel, and the image is changed in a change direction (for example, up and down direction).
When each dot is divided by one dot, the setting of which dot position is to be displayed at the first dot position in the vertical direction of the display area 41a, 41b or 41c is performed. That is, the coordinates of each of the four corners of the three display areas 41a to 41c for displaying the special symbols N1 to N3 on the display screen 41 are determined, and the coordinates of each of the above points are continuously changed, so that each of the display areas is changed. The images constituting the special symbols N1 to N3 in 41a to 41c change continuously.

In the "director file animation control task" shown in FIG. 14, first, it is determined whether or not the display screen 41 is in an animation initialization state (step S).
81) If it is an initialization state, initialization of animation data is performed (step S82). It is determined that the display screen 41 is not in the initialization state of the animation, or
When step S82 is executed, an “animation control process” described later is executed (step S83), a process for waiting for task control is executed (step S84), and the process returns to step S81 again. Therefore, each time the animation is initialized, the initialization of the animation data and the “animation control processing” are executed.

"Animation control processing" shown in FIG.
First, the display period is checked using a counter (not shown) in the display control circuit 60 (hereinafter, referred to as a display period counter) as a timer for managing the number of animation frames set (step S13).
1). Then, from the current animation display data (hereinafter referred to as display coordinate data) and the next display coordinate data, it is determined whether or not the display period (set value of the display period counter) needs to be reset. If there is, the difference between the current display coordinate data and the next display coordinate data is adjusted (step S133). If resetting is not necessary, the display period counter is incremented by one from the start of display (step S132), and then it is determined whether the value of the display period counter is lower than the value of the designated display period. (Step S134). If the value of the display period counter is lower than the value of the designated display period, the current “animation control process” is ended.

On the other hand, if it is determined in step S134 that the value of the display period counter is not smaller than the value of the designated display period, the data of the animation sequence program (animation pointer) set in the received command analysis processing ends. It is determined whether or not the code has been reached (step S135). Here, the animation sequence program is composed of a plurality of data to which respective addresses are assigned, and each data is read and processed in the order of the addresses. The data constituting the animation sequence program includes a reach effect code, an effect pattern determination process execution code, and an end code. In the reach effect code, animation data based on the “effect group” selected under the control of the special symbol game and the number of animation frames are set. The effect pattern selection processing execution code includes an effect pattern selection / selection that determines and determines the animation that is the content of the normal effect from the start of the fluctuation to the reach effect.
An execution request for the determination process and the number of animation frames of “normal effect” are set. The end code indicates the end of the animation display.

If the data of the animation sequence program has not reached the end code, the work RA
The address of the animation pointer which is a predetermined area of M62 is added up to the address of the next data (step S
136). For example, the address of the animation pointer is added up to the address of the animation data of the standby screen, which is the next data. Next, it is checked whether or not there is a jump code designating jumping to the specified address (step S137). If there is, the address data of the animation pointer is saved in the jump pointer (specified address) (step S137). S13
8). Next, the next animation data is loaded according to the animation pointer (step S139),
The display period counter is cleared to zero (step S14)
0).

"V_Sync interrupt processing" shown in FIG.
Is an interrupt process that is performed every 16.6 msec (1/60 second), and is synchronized with the start timing of the non-display period of the display screen 41. During the non-display period, the data of the next address of the animation data stored in the above-described animation pointer is transferred to the VDP 65 (step S165), and after the display coordinate data of the special symbol is transferred (step S166), A task control process for controlling the operation of the started task is executed (step S167). In this task control process, each task performs processing by V_Sync (Vertica).
l Synchronizing signal (vertical synchronizing signal), and the operation is temporarily passed to the task control processing. When the animation data is input, the VDP 65 reads dot data corresponding to the animation data from the image ROM 64 and generates image data to be displayed. Then, the generated image data is converted into an RGB signal by the D / A converter 66 and output to the display screen 41. (Direction display in case of humming)

Next, the display screen 4 in the case where the hammer occurs
A specific example of the effect display in No. 1 will be described.

FIG. 17 shows a simplified description of the effect display on the display screen 41 when a break occurs in the gaming machine 10.

First, when the start winning prize is detected by the start winning ball sensor 33 (the processing of the above-mentioned step S21), the main control circuit 50 determines whether or not the changing game of the special symbols N1 to N3 is a big hit. 171 (the processing in step S23 described above) is executed, and the big hit determination processing 17
If the result of the determination in 1 is a loss, the special symbol game counter 1 addition process 172 (the process of step S32 described above) for adding 1 to the special symbol game counter is executed, and the determination result in the big hit determination process 171 is a big hit. If there is, a special symbol game counter reset process 173 (the process of step S34 described above) for resetting the value of the special symbol game counter to 0 is executed. The main control circuit 5
0 determines the stop mode (stop symbol) of the special symbols N1 to N3 (the process of step S25, S28 or S29 described above) or the special symbol N1 to N3 according to the determination result in the big hit determination process 171. The pattern numbers of the variation pattern and the effect display pattern are determined (step S24 described above).
Or the processing of S26).

Next, the display control circuit 60 determines whether the special symbols N1 to N3 are stopped by the main control circuit 50 and the pattern determined by the main control circuit 50 in accordance with the processing shown in FIGS. Special symbol N obtained from the number
