[0002]

2. Description of the Related Art For example, in a pachinko game machine, which is a kind of ball game machine, in recent years, a game machine in which an electric display device such as a liquid crystal display device is provided in the center of a game board has become widespread. In this electric display device, a plurality of special symbols represented by images are variably displayed, and three rows of rotating reels of the slot machine are pseudo-displayed. When the variable display of the special symbols is stopped and a predetermined stop mode (a stop mode in which the same special symbols are gathered like "7-7-7") is brought, a special game state advantageous to the player Transition to. In a general pachinko gaming machine, the variable display of the special symbol is started on condition that the game ball wins a predetermined winning opening, and the special symbol is stopped and displayed after a predetermined time has elapsed.

In such a gaming machine, a special symbol required for determining whether or not to shift to a special gaming state is required to be easy for a player to see. For example, there has been proposed a gaming machine that employs a method of gradually enlarging the display area of the symbol in synchronization with the lowering of the symbol and the lowering of the fluctuation speed (JP-A-11-156014).

[0004]

However, by gradually enlarging the display area of the symbol, it becomes easier to see the symbol, but the proportion of the display area of the symbol to the display area of the entire display device increases. Therefore, there is a problem that the display area for performing the effect display other than the display of the symbols is gradually reduced, the content of the effect display is limited, and the interest of the player in the game or the interest of the game is halved. there were.

It is an object of the present invention to provide a gaming machine and a game program in which special symbols are easy to see and the display area of the display means can be effectively utilized.

[0006]

The gaming machine of the present invention has a display state (for example, a liquid crystal display device 4 described later) for displaying a special symbol, and a game state in which a special symbol stop mode is advantageous to the player ( (For example, a special game state called "big hit")
The control means (for example, the main control circuit 30 to be described later) that determines whether or not the shift mode to shift to (1) And a display control circuit 31), and the control means controls the display means so as to momentarily enlarge and display the special symbol when the special symbol is stopped and displayed.

In a specific mode of the present invention, the display means performs a display of the special symbol and an effect display different from this display (for example, a display of the character B overlapping with the special symbol as described later), and the control means The display means is controlled so that the special symbol is momentarily enlarged and displayed corresponding to the change in the mode of the effect display.

In a specific mode of the present invention, the control means controls the display means to momentarily enlarge and display the special symbol, and then displays the special symbol to be momentarily reduced and displayed. It is characterized by controlling means.

Further, according to the present invention, the function of displaying a special symbol on the display means (for example, the liquid crystal display device 4 described later) of the gaming machine (for example, the function of ST82 of FIG. 10 described later),
A function (for example, a function of ST34 in FIG. 6 described later) for determining whether or not the stop mode of the special symbol is a stop mode for shifting to a game state advantageous for the player (for example, a special game state), the determination thereof The function of controlling the display means based on the result (for example, the function of ST65 in FIG. 8 described later), and when the special symbol is stopped and displayed, the display means is controlled so that the special symbol is momentarily enlarged and displayed. A game program for causing a computer to realize the function (for example, the processing of ST66 in FIG. 8 described later) is provided.

[0010]

In the gaming machine of the present invention, the control means controls the display means so as to momentarily enlarge and display the special symbol when the special symbol is stopped and displayed. Therefore, the special symbol becomes easy to see, and since the period until the special symbol is enlarged and displayed is short, the display area of the display means can be effectively used.

In the embodiment of the present invention, the special symbol is momentarily enlarged and displayed in response to the change in the mode of the effect display, so that the force and interest of the effect display can be increased.

Further, the display area of the display means can be effectively used by instantaneously reducing and displaying the special symbol. Here, the size of the special symbol when reduced and displayed can be arbitrarily determined as long as it is smaller than the size when enlarged and displayed. For example, as the special symbol when reduced and displayed, it is possible to adopt the same size as before being enlarged, or the one smaller than the size before being enlarged. If the size is made smaller than the size before the enlargement, a more effective effect is possible.

Further, according to the present invention, even in a home-use game machine, for example, a game similar to the game of the above-mentioned game machine can be enjoyed.

Based on the command output by, the launch device 42 for launching the game ball into the game area 3 and the prize ball device 43 for paying out the prize ball are controlled.

Next, the control processing operation executed by the main MPU 30a of the main control circuit 30 will be described with reference to FIG.

When the power is first turned on, the main MPU
Startup processing is performed at reset (step [below,
Display as ST] 1). Next, the main MPU 30a
Probability setting processing is performed (ST2), and interrupt permission is enabled (S
T3). Here, when the interrupt is permitted, the interrupt process shown in FIG. 5 described later is started. Subsequently, an error notification process is performed (ST4), and a special symbol game control process is performed (ST5). This special symbol game control process will be described later with reference to FIGS. 6 and 7.

Next, the interrupt processing will be described with reference to FIG.

First, the main MPU 30a saves each register (ST11) and performs random number update processing (ST).
12). Here, the counter values of the big hit determination random number counter (not shown), the outlier symbol determining random number counter, the big hit symbol determining random number counter, and the display pattern number determining random number counter are updated. The big hit determination random number counter is used to determine whether or not to shift to the special game state. The random symbol counter for determination of outliers is used to determine three special symbols (stop symbols) to be stopped and displayed in each row when it is determined to be out of contact in the determination of whether or not to be a big hit (big hit determination). To be The jackpot symbol determination random number counter is used to determine three special symbols (stop symbols) to be stopped and displayed in each row when it is determined to be a "big hit" in the jackpot determination. The display pattern number determining random number counter is used when determining a display pattern number described later.

Next, the main MPU 30a performs timer updating processing such as an animation display time management timer described later (ST13). Here, the update process of the timer required for the game process is performed. Next, input port processing is performed (ST
14), each input signal processing is performed (ST15). In each input signal processing, the big winning ball sensor 20a, the passing ball sensor 20
Processing based on the input signals from b, the winning ball sensor 20c, the starting winning ball sensor 20d, the launching ball sensor 20e, and the returning ball sensor 20f is performed. Starting prize ball sensor 20d
When there is an input from, the main MPU 30a stores the values of the big hit determination random number counter, the big hit symbol determination random number counter, etc. at that time in the main RAM 30c.

Next, the main MPU 30a performs normal symbol processing (ST16) and prize ball payout processing (ST1).
7), error processing for processing error signals generated from various devices is performed (ST18). Then, ST41 described later
Output processing of transmission data such as commands generated in (FIG. 6) and stored in the main RAM 30c is performed (ST
19), and outputs the transmission data (ST20). Then, each register saved in the above-mentioned ST11 is restored (ST21), and interruption is enabled (ST22).

Next, the special symbol game control processing will be described with reference to FIGS. 6 and 7.

First, whether or not there is a start winning, that is, the value of the big hit determination random number counter or the like is stored in the main RAM 30c based on the input from the starting winning ball sensor 20d in the input signal processing of ST15. It is determined whether or not (ST31). If this determination is "NO", demo display processing is performed (ST32).

If the determination in ST31 is "YES", a random number extraction process for determining the display pattern number is performed (ST3.
3). In this process, a random number is extracted from the range of "0" to "16383" using the display pattern number determining random number counter. There are "1" to "15" in the display pattern numbers determined in the processes of ST35 and ST37 described later. The display pattern number is transmitted to the display control circuit 31 as a "display pattern designation command" based on the processing of ST41 described later. In the case of "disappearance", if any of "1" to "8" is selected as the display pattern number, the reach is determined not to occur. Also, as the display pattern number, "9" to "1"
If any of the 5 "is selected, reach is generated." Display pattern designation command "
Is for designating a time from the start of movement of the special symbol to the stop thereof. The display control circuit 31 controls the liquid crystal display device 4 based on a “display pattern designation command” or the like.

Then, it is determined whether or not it is a big hit (ST3).
4). In this process, a random number is extracted from the range of "0" to "334" using the jackpot determination random number counter, and if the random number value is "7", it is determined to be a jackpot.

When the determination in ST34 is "YES", S
The display pattern number is determined based on the display pattern number determining random number extracted in the process of T33 (ST35).
Next, using a random number counter for jackpot symbol determination, "0" ~
A random number value is extracted from the range of "9" to determine a big hit symbol (ST36). Here, for example, when the random number value is "7", "7" is stopped and displayed as the stop symbol in each column.

Subsequently, a "display pattern designation command" and a "stop display special symbol designation command" are generated based on the processing of ST35 and ST36 (ST41), and these commands are stored in the main RAM 30c (ST.
42). The "stop display special symbol designation command" is a command for designating a special symbol (stop symbol) to be stopped and displayed in each column. For example, when the random number value extracted in the process of ST36 is "7", "stop display special symbol designation command"
Indicates that the special symbol “7” is stopped and displayed in each column. The command stored in the main RAM 30c is transmitted to the display control circuit 31 by the processing of ST19 and ST20 described above.

If the determination in ST34 is "NO", that is, "disappear", the display pattern number is determined based on the random number for determining the display pattern number extracted in the process of ST33 (ST37). Subsequently, it is determined whether or not the display pattern number is "9" to "15", that is, whether or not reach is generated (ST38). When this determination is "YES", by using the random number counter for determining the off symbol, the special symbol (stop symbol) to be stopped and displayed in each row is determined so that the reach occurs but the out symbol occurs (ST).
39). When the determination in ST38 is "NO", a special symbol (stop symbol) to be stopped and displayed in each column is determined so that the reach does not occur and the shift occurs (ST40). continue,
The main MPU 30a has ST37, ST39, and ST
Based on the process of 40, the processes of ST41 and ST42 are performed.

Next, as shown in FIG. 7, the main MPU 3
0a performs an animation display time check process (ST43). In this process, the above-mentioned ST35 or ST
The animation display time determined for each display pattern number in 37 is set in the animation display time management timer. The animation display time is the time from when the special symbol starts moving (FIG. 2 (1)) until the special symbol is stopped and displayed in all columns. The animation display time management timer is subtracted in the process of ST13. Subsequently, it is determined whether or not the animation display time management timer is "0" (ST44). If this determination is "YES", the process proceeds to ST45, where "N" is entered.
When it is "O", the process proceeds to ST43.

Next, the "confirmation display command" is issued to the main RA.
The data is stored in M30c (ST45). By transmitting this “confirmation display command” to the display control circuit 31, the stop of the special symbol displayed on the liquid crystal display device 4 is confirmed.

Next, it is determined whether or not a big hit is determined in the above-mentioned determination in ST34 (ST46), and this determination is "N".
If it is "O", the process is terminated. On the other hand, if it is "YES", "big hit fanfare process" is performed (ST4).
7). In this big hit fanfare processing, a "big hit fanfare display command" indicating a request for big hit fanfare display is stored in the main RAM 30c.

Next, the main MPU 30a performs a round display switching time check process (ST48). In this process, the time from when the special winning opening 8 is closed to when the special winning opening 8 is opened next is managed. Specifically, the "round switching timer" starts counting when the special winning opening 8 is closed in the special winning opening opening / closing process (ST50) described later.

Next, special game state time check processing is performed (ST49). In this processing, the time for maintaining the open state of the special winning opening 8 (for example, 30 seconds), the time for which the special winning opening 8 is set as a specific area, and the like are managed. Subsequently, a special winning opening / closing process is performed (ST50). In this process, the special winning opening 8 is opened when the count value of the "round switching timer" in ST50 reaches a predetermined value. Also, ST50
In the processing, the closing processing of the special winning opening 8 is performed when the number of game balls winning the special winning opening 8 reaches a predetermined number or based on the special game state time check processing of ST49. The main MPU 30a performs a special game state display process (S
T51). In this process, when the special winning opening 8 is opened,
When the game ball passes through the specific area and when the special winning opening 8 is closed, a predetermined command is stored in the main RAM 30c.

Next, the main MPU 30a has a big winning opening 8
Is determined to be in the open state (ST52). When the determination is "YES", the process returns to ST48 and "NO".
In case of, move to the next step (ST53). ST53
In the processing of (1), it is determined whether or not the game ball has passed through the specific area and whether or not the special winning opening 8 has been opened for a predetermined number of times (for example, 16 times) (ST53). If this determination is "YES", the process returns to ST48, and if "NO", the special game state end process is performed (ST54).

Next, main processing in the display control circuit 31 will be described with reference to FIG.

First, the operation of the sub MPU 31a is initialized (ST61). Then, sub MPU 31a
Clears the data stored in the work RAM 31c (ST62) and initializes the operation of the VDP 31d (ST63). Next, the sub-MPU 31a operates the work RA.
The command stored in M31c is read and the received command analysis process is performed (ST64). The command transmitted by the main control circuit 30 is stored in the work RAM 31c by the command interruption management process described with reference to FIG. In this received command analysis processing, the read command is interpreted and the parameters of the VDP 31d are set.

Next, the sub MPU 31a performs a special symbol control process which will be described later with reference to FIG. 10 (ST6
5), animation display control processing is performed (ST6
6). In this animation display control process, the display content of the display screen 4a is determined based on the result of the received command analysis process, and the liquid crystal display device 4 is controlled. Subsequently, it is determined whether or not the "1 frame processing flag" indicating that the display of the image "1 frame" on the display screen 4a has been set. If the determination is "YES", S
The process moves to T64.

Next, the command interrupt management processing will be described with reference to FIG.

First, the sub MPU 31a stores the received command in the work RAM 31c (ST71).
Then, it waits until a command is received (ST7
2).

Next, the special symbol control process will be described with reference to FIG.

First, the sub MPU 31a performs a special symbol display sequence process (ST81). In this process,
The determination regarding the display of the special symbol based on the received "stop display special symbol designation command" and "display pattern designation command" is performed. Then, the sub MPU 31a performs a special symbol display process (ST82). In this process, ST81
Based on the determination, the liquid crystal display device 4 is controlled to display the special symbols in each row.
