Description

  The present invention relates to a gaming machine, and particularly relates to a gaming machine having a probability variation function and a time shortening function.

  Conventionally, in a gaming machine equipped with a variable display device for displaying a special symbol, a variable variable display game in the variable display device is started by winning a special symbol start opening, and variably displayed after a predetermined time has elapsed. When the symbol is stopped and the stop symbol becomes a stop display mode indicating the occurrence of a big hit state such as a flat eye, for example, a big hit state (a state where the game ball is easily acquired by the opening operation of the variable winning device etc.) It is common to generate a special gaming state.

  In particular, in recent years, there are many gaming machines that use a liquid crystal display device, a CRT display device, or the like as a variable display device and perform a variable display game by displaying a plurality of identification information images. When a big hit state occurs in a conventional gaming machine as described above, the variable display device of the gaming machine has a stop symbol, the number of rounds (number of continuations), or the number of counts (variation per round) when the big hit state occurs. The effect display during the big hit state is performed by displaying the number of winnings in the winning device) and the operation display by the character (for example, the display of the character traveling around the world).

  Also, recently, in this type of pachinko gaming machine, when the stop display mode at the time of jackpot occurrence is based on a specific symbol (probability variation symbol) such as 1, 3, 5, 7, etc. ( For example, “3, 3, 3”, “7, 7, 7”, etc.) After the big hit gaming state, the special symbol is variable until the next big hit occurs a predetermined number of times (for example, once or twice). There is also known a pachinko gaming machine that generates a probability variation state in which the probability of jackpot in a display game is changed to a high probability state.

  Similarly, a special symbol starting port is provided with a normal electric accessory, and a normal symbol that determines whether the normal electric accessory is opened or closed, and when the big hit occurrence symbol is a specific symbol, Increase the winning rate to the start opening and increase the winning rate by opening the normal electric accessory frequently with the probability per normal symbol set to a high probability state until the big hit occurs a predetermined number of times (once or twice) A gaming machine having a function of speeding up the occurrence of the problem is also known.

  When a probability variation state as described above occurs, if a big hit occurs again with a specific probability variation pattern during the probability variation state, the probability variation state where the probability variation state starts again from the initial state The update continuation function is often provided.

  Furthermore, the variation time of the normal symbol is made shorter than that in the normal gaming state (for example, from 30 seconds to 5 seconds), and the opening pattern of the ordinary electric accessory when the normal symbol is hit is changed (for example, 0.5 There is also a game machine with a short-time function that increases the winning rate at the start opening by increasing the chances of opening the ordinary electric accessory by opening from 1 second of 1.5 seconds to 3 times of 1.5 seconds) In this case, for example, the normal symbol time reduction game as described above is generated until the special symbol fluctuates 50 times after the end of the big hit.

However, the relationship between the conventional probability variation function and the time-shortening function is, for example, that the number of changes in the special symbol is set to the same predetermined number of times for both the probability variation and the time-shortening. Resulting in. Therefore, the player's interest may be lost in a situation where the high-probability state or the short-time state ends immediately, such as when the number of times is small.
Furthermore, since the timings of the probability variation function and the short-time function are synchronized each time, it is not possible to sufficiently perform the continuous jackpot effect, and the game is not sufficiently interesting.

  In view of the above, an object of the present invention is to provide a gaming machine that improves the relationship between the probability variation function and the time-shortening function and improves the preference.

Means and effects for solving the problems

In order to solve the above-mentioned problem, the gaming machine according to claim 1,
Starting means that cause the pattern to stop fluctuating,
Condition establishment determination means for determining whether or not to execute a game advantageous to the player;
When the symbol is variably displayed due to the operation of the starting means, and when the condition is established by the condition establishment determining means, the advantageous notification symbol that the game advantageous to the player is executed, the condition is not established Informing symbol display means for displaying a disadvantage notification symbol that the advantageous game is not executed,
When the game is stopped and displayed with the advantage notification symbol, after a game advantageous to the player is executed, in a predetermined case, a probability improvement period for improving the probability that the symbol is displayed with the advantage notification symbol, Thereafter, probability variation means for reducing the probability,
Profit state giving means for shortening the time of change of the symbol and making the starting means in an operating state advantageous for the player after executing a game advantageous to the player when the advantageous notification symbol is stopped and displayed. In a gaming machine equipped with
Provide a plurality of end timings of the probability improvement period by the probability variation means,
In the gaming machine, the end timings of the plurality of probability improvement periods are different from the end timing of the profit grant period by the profit state granting unit.

  2. The ball game machine according to claim 1, wherein the ball game machine according to claim 1 has a plurality of end timings of the probability improvement period by the probability changing means, and the end timings of the plurality of probability improvement periods are all assigned to the profit state. By making it different from the end timing of the profit granting period by means, it is possible to realize a game with a structure that has not existed in the past, and to solve the above problem suitably.

  Here, examples of the “starting means” include a starting port (a prize opening, a winning port, a normal electric accessory, etc.) or a starting gate, and a game ball entering the starting gate or a game ball entering the starting gate. The symbol stops fluctuating due to the passage. The “profit state granting means” says “the starting means is in an operating state advantageous to the player”. Specifically, the change time of a symbol (for example, a normal symbol) displayed on another display means is set. For example, shortening the number of opportunities for the starter to operate, or increasing the number of operations of the starter, extending the operation period, and the like.

  “Condition establishment determination means for determining whether or not to execute a game advantageous to the player” is, for example, that a game ball launched on the game board surface enters a specific entrance or passes a specific passage It is determined whether or not the game content is advantageous to the player in accordance with the random value extracted due to the timing of the game. The term “advantageous game” here refers to a state that is directly advantageous to the player based on a random number value extracted due to the timing of entering a specific entrance or passing through a specific entrance. This is naturally included, and a predetermined winning entrance (entrance entrance) is opened by a random number value extracted due to the timing of entering or passing through a particular entrance entrance. A so-called type 3 gaming machine (right), an arrangement ball gaming machine, or other type 1 or type 3 pachinko machine that makes the player in an advantageous state when the game ball passes through a specific area in the opened special winning opening. It also includes game contents that are indirectly advantageous to the player, such as gaming machines that are combined by appropriately combining machines. It should be noted that a configuration in which a game ball as a winning ball is paid out along with a winning ball (in this case, often referred to as a “winning port”) or a configuration in which no gaming ball is paid out may be employed.

  “Notification symbol display means” means, for example, whether or not the game content is advantageous to the player after variably displaying the symbols on the screen every time it is determined whether or not the game content is advantageous to the player Any symbol may be used as long as it is controlled so as to be displayed statically with an advantageous notification symbol indicating, and a symbol indicating that the game content is advantageous to the player is, for example, a symbol that displays the same three-digit symbol such as “777”, The symbol that the main character (hero) wins in martial arts, the symbol that the main character wins in the race, the symbol that the main character wins or the goal in ball games, the symbol that the main character finds a treasure in an adventure story, the main character or the main character The pattern which shows a happy state can be considered, for example, people who are related to the benefit. In addition, the “disadvantage notification symbol” includes a symbol that displays a three-digit non-identical symbol such as “769”, a symbol that indicates that the main character is unhappy, and the like. The “notification symbol display means” includes a display unit of a device capable of displaying the symbol, such as a dot matrix display and a 7-segment LED, as well as a screen of a CRT and a liquid crystal display.

  The “symbol” is displayed on the screen and may be a special symbol, background, or character, or a combination thereof. For example, it includes numbers, letters, symbols and figures indicating people and animals, and specific colors of specific shapes. The shape of the pattern does not need to change or may change. For example, they may be the same or enlarged / reduced.

It is configured as.

Processing executed by an 8-bit one-chip microcomputer (hereinafter simply referred to as “microcomputer”) in the main control board 30 of the pachinko machine 10 having the circuit configuration described above will be described according to a flowchart shown in FIG.
The flowchart shown in FIG. 5 represents a main process executed by the microcomputer of the main control board 30, and is a process periodically executed by a hardware interrupt about every 2 ms. In the present embodiment, each process from step S10 to step S60 is a process that is executed only once in the interrupt process, and is referred to as “main process”. As long as time is allowed within the remaining time after executing this main process. The processing of steps S65 and S70 that are repeatedly executed is referred to as “residual processing”.

When a hardware interrupt is executed by the microcomputer, it is first determined whether or not the interrupt is a normal interrupt (step S10). This determination process is performed by determining whether or not the value of a predetermined area of the RAM as a memory is a predetermined value. When the process executed by the microcomputer shifts to this process, the normal process is executed. It is for judging whether it is okay. As an unusual case, a microcomputer runaway due to noise or the like may be considered when the power is turned on, but the microcomputer runaway may be considered to be almost impossible due to recent technological improvements, and is usually at the time of power on. When the power is turned on, the value in the predetermined area of the RAM is different from the predetermined value.
If it is determined that it is not normal, each initial value is written to the memory work area, such as a predetermined value is written in the predetermined area of the memory, a special symbol and a normal symbol are set as an initial symbol, that is, initial setting is performed ( Step S15), the process proceeds to the remaining process.

  If a positive determination is made, an initial random number update process is first executed (step S20). This process is an increment process that increments the initial random number value by 1 each time this process is executed. The initial random number value before this process is incremented by one, but the random value before this process is executed is the maximum value. When it is “299”, it returns to the initial value “0” in the next processing, and 300 integers from “0” to “299” are repeatedly generated in ascending order.

  The success / failure random number update process (step S25) subsequent to step S20 is an increment process that is incremented by 1 every time the process is executed, as in the initial random number update process. However, when the maximum value “299” is reached, The initial random number at that time is set as an initial value (hereinafter referred to as “update initial value”), and further incremented by +1 for each interrupt, and a value “1” less than the update initial value (hereinafter referred to as “maximum update”). In the next processing, 300 integer values from “0” to “299” are repeatedly created with the initial random number at that time as the initial value.

  That is, +1 is added for each interrupt process, and setting the elements constituting the random number to an integer value from “0” to “299” is not different from the initial random number. In this interrupt processing, the update initial value at that time is set as the initial value, and +1 is added for each interrupt until the update maximum value is reached, and the next update initial value is set as the initial value. As a result, the random number is set to 300 integer values from “0” to “299” as elements constituting the random number, and is incremented by +1 for each interrupt process. Since it is changed to a value determined by the initial random number, the value of the random number can be made unpredictable. In addition, the constituent elements of the random number determined by the update initial value and the update maximum value are the same as the 300 integer values “0” to “299” that are the same as the conventional pass / fail random numbers, and thus the elements constituting the random numbers The appearance rate is made uniform.

  The jackpot symbol random number update process (step S30) is configured as a counter that repeatedly creates 15 integers “0” to “14”, and is incremented by 1 every time this process is exceeded and the initial value is “0”. Return to. Each of the 15 random numbers “0” to “14” is “111”, “222”, “333”, “444”, “555”, “666”, “ 777 ”,“ 888 ”,“ 999 ”, [AAA”, “BBB”, “CCC”, “DDD”, “EEE”, “FFF”, respectively.

  The off symbol random number update process (step S35) is composed of a random symbol for the left symbol, a random number for the middle symbol, and a random number for the right symbol, and is used as a miss symbol when it is not a big hit. The left symbol random number is configured as a counter that repeatedly generates 15 integers “0” to “14”, and is incremented by 1 every time this process is exceeded, and returns to the initial value “0”. The medium symbol random number is configured as a counter that repeatedly creates 15 integers from “0” to “14”. When the left symbol random number returns to “0”, it is incremented by 1 every time this process exceeds the maximum value. Return to "0". The right design random number is configured as a counter that repeatedly creates 15 integers from “0” to “14”. When the medium design random number returns to “0”, it is incremented by 1 every time this process is exceeded and exceeds the maximum value. Return to "0".

  The normal symbol random number update process (step S40) is configured as a counter that repeatedly generates seven integers “0” to “6”, and is incremented by +1 for each process and is an initial value “0”. Return to.

The initial random number, the success / failure random number, the jackpot symbol random number, the off symbol random number, and the normal symbol random number are respectively updated by each of the random number update processes (steps S20 to S40) described above. The input processing of each switch connected to the main control board 30 is executed. In this embodiment, the full switch 43, the replenishment switch 44, the touch switch 24a, the first type start port switch 36a, the V switch 40a, the count switch 40b, the normal symbol operation switches 38a and 39a, and the other winning ports are provided. A process of checking the operating state of each switch such as each winning detection switch (not shown) is executed.
When there is an input to the first type start port switch 36a by this input process, it is the time when a game ball wins the ordinary electric accessory 36 as the start port, and the value of the success / failure random number at the time of this interrupt process is extracted. The result is compared with an appropriateness determination value.

  The pachinko machine 10 of the present embodiment is configured as a probability variation machine, and the success / failure determination value is “1” at the normal probability, and “1”, “3”, “5”, “7”, “ 9 ”. As described above, the appearance rates of the 300 integer values of “0” to “299” constituting the success / failure random number are uniform, and are extracted at the timing when the game ball wins the ordinary electric accessory 36 as the starting port. The value of the random number is a randomly extracted value because the winning timing cannot be adjusted in minute time units as compared with 2 ms which is the minute time of the hard interrupt, and the wrong number functions as a complete random number. Accordingly, the probability that the extracted random number value matches the true / false determination value and is a big hit is 1/300 at the normal probability and 1/60 (= 5/300) at the high probability. In the present embodiment, the probability that the jackpot is generated shifts from the low probability state to the high probability state. In this embodiment, the value of the jackpot symbol random number in the interrupt processing when the jackpot occurs is “1”, “3”, “ 5 ”,“ 7 ”,“ 9 ”,“ 11 ”, and“ 13 ”(hereinafter referred to as“ high probability random value ”), with a high probability of 7/15 when a big hit occurs. Transition. If the value of the jackpot symbol random number when the jackpot is generated again during the high probability is high, the higher probability state continues. That is, every time the high probability state is entered, there is a possibility that the high probability continues with a probability of 7/15.

Subsequently, a success / failure determination process (step S50) for determining whether or not a big hit is made. When this success / failure determination process (step S50) is completed, an image output process (step S55) is subsequently executed.
This image output process (step S55) will be described in detail with reference to FIG. The command code shown in FIG. 7 is a code transmitted from the main control board 30 to the symbol control board 32b of the special symbol display device 32.

  As shown in FIG. 7, the transmission command codes of the main control board 30 and the symbol control board 32b of this embodiment are 1. 1. When power is turned on 2. Demonstration waiting for customers. 3. During design fluctuation. 4. At the start of jackpot During the big hit, 6. 6. At the end of jackpot It can be roughly divided into 7 types when operation is abnormal.

1. When the power is turned on, the command when turning on the power is a command code transmitted from the main control board 30 to the symbol control board 32b when the pachinko machine 10 is turned on. The command is a 2-byte command having an operation number 10H and an identification number 01H. It is configured. When the symbol control board 32b receives this command, a demonstration screen at power-on is displayed on the screen of the LCD 32a according to the control program written in the ROM.

2. Customer Waiting Demo A customer waiting demo command is sent after the demo screen when the power is turned on or when it is determined that the player has not touched the firing handle 24 for a predetermined time (usually about 3 minutes). This is a command and is composed of a 2-byte instruction having an operation number 20H and an identification number 01H. When the symbol control board 32b receives this command, a demonstration screen waiting for the customer is displayed on the screen of the LCD 32a according to the control program written in the ROM. For example, all the special symbol variation patterns that are variably displayed on the special symbol display areas 50a to 50c shown in FIG. 6 are sequentially displayed. Further, the on-hold storage display portions 51a to 51d are sequentially turned on and displayed. At this time, a background image and a character corresponding to each variation pattern are displayed on the background screen 52. This waiting-for-customer demonstration screen displays all the variation patterns in order until the player operates the firing handle 24, and then repeatedly displays them. Note that whether or not the player is touching the firing handle 24 can be detected by the input of the touch switch 24a. In this embodiment, since the input of the touch switch 24a is input to the main control board 30, the detection is performed while the communication between the main control board 30 and the launch control board 33 is one-way communication from the main control board 30. Is possible. Of course, on / off information of the touch switch 24 a is transmitted from the main control board 30 to the launch control board 33. The input of the touch switch 24a is configured to be input to the launch control board 33, and there is no winning for a predetermined time at any or all of the winning openings, or a switch is provided at the out opening 41 on the surface of the game board 22. A configuration may be adopted in which it is determined that the player is not playing a game by not turning it on for a predetermined time.

3. The symbol changing command is a command generated by the main control board 30 and transmitted from the main control board 30 to the symbol control board 32b when the special symbol changes. As shown in FIG. , (2) left still symbol designation code, (3) middle stationary symbol designation code, and (4) right stationary symbol designation code (hereinafter, these four command codes are collectively referred to as “image display command”). ”).

(1) Fluctuating time code Fluctuating time codes are composed of 30 types of 1-byte instructions as operation numbers and 30 types of 1-byte instructions of 01H to 1EH as identification numbers as 30 types of 2-byte instructions. Thirty types of 1-byte instructions represent 30 types of time from 5 seconds to 35 seconds in units of 1 second.

(2) Left stationary symbol designation code The left stationary symbol designation code is an instruction code consisting of an operation number of 31H and 15 types of identification numbers of 01H to 0FH. When the identification number is 01H, the left stationary symbol designation code is “0”. "1" for 02H, "2" for 03H, "3" for 04H, "4" for 05H, "5" for 06H, "6" for 07H, “7” for 08H, “8” for 09H, “9” for 0AH, “A” for 0BH, “B” for 0CH, “C” for 0DH, 0EH When “D”, the character “E” is displayed as a special symbol in the special symbol display area 50a.

(3) Medium stationary symbol designation code The middle stationary symbol designation code is an instruction code consisting of 32H operation number and 15 types of identification numbers 01H to 0FH. The identification number is the identification number of the left stationary symbol designation code. The characters having the same meaning are displayed in the special symbol display area 50b as special symbols.

(4) Right stationary symbol designation code The right stationary symbol designation code is an instruction code composed of an operation number of 33H and 15 types of identification numbers of 01H to 0FH. The identification number is an identification number of the left stationary symbol designation code. The characters having the same meaning are displayed in the special symbol display area 50c as special symbols.

  This variable time code, left, middle and right stationary symbol designation codes are sent almost simultaneously to the symbol control board 32b in units of 2 bytes when a game ball launched on the game board 22 wins the ordinary electric accessory 36 as a starting port. This is a command code to be transmitted, and its content is determined as follows.

  As described above, when the game ball wins the ordinary electric accessory 36, the value of the success / failure random number, the value of the jackpot symbol random number, and the value of the off symbol random number are extracted. The extracted success / failure random value is compared with the success / failure determination value “1” at the normal probability, and the success / failure determination values “1”, “3”, “5”, “7”, “9”, and “11” at the high probability. If it matches, a big hit will be generated, otherwise it will be missed. When a big hit occurs, the extracted big hit symbol random number value is incremented by 1 and this value is used as the identification number of the left, middle and right stationary symbol designation codes. That is, the identification numbers of the left, middle and right stationary symbol designation codes are the same. If they do not match and are out of place, left, middle, and right stationary symbols are specified by adding 1 to each of the random values for the left symbol, random value for middle symbol, and random value for right symbol of the extracted random symbol The code identification number. At this time, if the three identification numbers coincide by chance, a process is performed in which the identification number value of the right stationary symbol designation code is set to a value different by “1”. The above-mentioned variable time code is a large value when the identification numbers of the left, middle and right stationary symbol designation codes all match, and is an intermediate value when the identification numbers of the left and middle stationary symbol designation codes do not match. If they do not match at all, they are sorted into smaller values.

  A process performed by the symbol control board 32b when an image display command composed of these four command codes is received will be described. Details of reach and reach determination probability control will be described later. When the microcomputer of the symbol control board 32b receives the image display command, it executes a process of creating a special symbol variation pattern from the received variation time and the identification numbers of the left, middle and right stationary symbol designation codes. In the ROM of the symbol control board 32b, as shown in FIG. 8, a table corresponding to each combination of values of the received image display command is written. The microcomputer of the symbol control board 32b reads the table written in the ROM from the received image display command and creates a special symbol variation pattern. This variation pattern is created as follows.

The microcomputer determines whether or not the left and middle identification numbers match from the identification numbers of the received left, middle and right stationary design designation codes (that is, whether or not it is a reach), and whether the fluctuation is normal or not. Judgment is made on reach fluctuations, and whether or not various fluctuations such as trick fluctuations are made depending on whether the fluctuation time value is larger or smaller than the predetermined value even in reach fluctuations. Each time from the start of the fluctuation of the left, middle and right symbols to the time of standing still is determined. In accordance with the variation pattern of the special symbol created in this way, the background and character display data displayed on the background screen 52 are also created.
Once the variation pattern is created, the left, middle and right special symbols start to vary according to the created variation pattern, and the process of displaying still images with the specified stationary symbols is executed. Executed.
If a game ball wins in the ordinary electric accessory 36 serving as a starting port during the change of the special symbol, a command code not shown in FIG. 7 is transmitted from the main control board 30 to the symbol control board 32b, and the reserved memory display is displayed. The parts 51a to 51d are lit and displayed.

4). Big hit start The big hit start demo command code says that a big hit has occurred after the left, middle and right special symbols displayed in the special symbol display areas 50a to 50c display the same symbol until the big hit operation starts. This command is used to display an image that appeals to the player, and is composed of an operation number of 40H and an identification number of 01H. When the command code is received by the symbol control board 32b, a character such as a big hit is displayed on the screen of the LCD 32a to display an image that the character is pleased with, and the sound control board 35 outputs a sound effect.
At this time, the symbol control board 32b determines that a big hit has occurred from the image display command, that is, whether or not the received identification numbers of the left, middle and right stationary symbol designation codes match. If the affirmative determination is made, the value of the number of jackpots stored last time is incremented by 1, and processing for displaying the number of times on the background screen 52 is executed.
Thereby, it is possible to notify the player of the total number of jackpots that have occurred in the pachinko machine 10 during business since opening the pachinko hall.

  Further, the symbol control board 32b determines from the image display command, that is, whether the received identification numbers of the left, middle and right stationary symbol designation codes match and whether the probability variation flag is set. If an affirmative decision is made that the jackpot has a high probability, the value of the jackpot number in the high probability stored last time is incremented by 1, and a process for displaying the number on the background screen 52 is executed. As a result, the player is notified of the number of big hits (so-called “continuous number of times”) with a high probability. The number of big hits during the high probability is cleared to zero when the high probability continuation is no longer executed, and is displayed again when the high probability continuation big hit occurs again. The symbol control board 32b stores the maximum number of hits with a high probability after opening the pachinko hall during business, and updates the value when a big hit with a high probability exceeding the maximum number occurs. The number of big hits in the high probability can be displayed together with the cumulative number of big hits.

5). Big hit Medium hit big hit commands are classified into five command codes: pre-open code, open code, 10-count winning code, V pass code and round display code.
(1) The pre-release code is composed of an operation number of 50H and an identification number of 01H. When the symbol control board 32b inputs this command code, an image that informs the player that the special winning opening 40 will be opened is displayed on the background screen. The process displayed on 52 is executed.
(2) The open code is composed of an operation number of 50H and an identification number of 02H, and when the symbol control board 32b inputs this command code, an image that informs the player that the big prize opening 40 is open. Processing to be displayed on the background screen 52 is executed.
(3) The 10-count winning code is composed of an operation number of 50H and an identification number of 03H, and the main control board 30 detects that a game ball has entered the big winning opening 40 by the count switch 40b or the V switch 40a. This instruction code is transmitted every time. When the symbol control board 32b inputs this command code, the value is incremented every time it is input, and the value is displayed on the background screen 52. Thereby, on the screen, the number of 0 to 10 is displayed every time a game ball wins the big winning opening 40.
(4) The V passing code is composed of an operation number of 50H and an identification number of 04H. When the main control board 30 detects that the game ball has passed through a special area in the big prize opening 40, this command is issued. Send the code. When the symbol control board 32b inputs this command code, the character “V” is displayed large on the background screen 52 to inform the player that the special winning opening 40 is closed and then opened again.
(5) The round display code is composed of an operation number of 50H and an identification number of 05H, and the main control board 30 transmits this instruction code every time the special winning opening 40 is opened again after the opening operation is completed. When the symbol control board 32b inputs this command code, the value is incremented every time it is input, and the value is displayed on the background screen 52. As a result, the player is notified of the number of times the special winning opening 40 is opened.

6). End of jackpot The jackpot end command consists of a jackpot end demo code and a high probability transition code.
The jackpot end demo code shows that when the jackpot action is finished, that is, when the big winning opening 40 finishes the 16 opening actions, or the game ball does not pass through the special area during the opening even if it does not continue up to 16 times. This is an instruction code that is sometimes transmitted, and is composed of an operation number of 60H and an identification number of 01H. When the symbol control board 32b inputs this command code, a message is displayed informing the player that the big hit has ended.
The high probability transition code is composed of an operation number of 61H and identification numbers of 01H to 02H. When the identification number is 01H, the high probability state is continued, and when the identification number is 02H, the high probability state is not continued. The high probability transition code may be configured to be transmitted from the main control board 30 as in the present embodiment, or may be configured to be determined by the symbol control board 32b from the value of the image display command described above. After the probability improvement period, the probability is low.

6.1 Short-time operation Short-time operation is performed in relation to the high probability period. There are various types of short operation at this time, and the contents thereof are well known, but an example will be described below. First, the time from when the special symbol variation display is started until the set symbol is displayed is shortened. The time is reduced when a special symbol (probability variable symbol) set in advance is selected from a plurality of (three digits here) special symbols displayed when the special symbol variation display is stopped. The time is reduced due to the establishment of a predetermined condition such as. By reducing the time (hereinafter also referred to as time reduction) in this way, the maximum number of times that the special symbol variation display is performed within a certain time is increased. Then, by shortening the special symbol variation display, the special symbol variation display can be performed at an early point in accordance with the start winning prize. For this reason, it is possible to avoid a situation in which the special symbol display cannot be operated promptly in spite of winning the normal electric accessory (start opening) 36.

  Further, as described above, the time of the normal symbol displayed on the normal symbol display device 37 is shortened along with the shortening of the variation time of the special symbol. By shortening the normal symbol variation display, the normal symbol display is activated many times within a predetermined time. Therefore, the number of times that the normal symbol display can be activated per time increases. If the normal symbol variation display is shortened, the number of times that the normal symbol is won increases, thereby increasing the number of times of operation of the ordinary electric accessory 36 and facilitating the start winning. Thus, by making it easy to start and win, it becomes difficult for the player's balls to be reduced, and a more advantageous game can be played. The relationship between the probability variation and the time saving will be described in detail later.

7). When abnormal operation The abnormal operation command is an instruction command that is sent when an abnormality occurs in the pachinko machine 10, and in this example, from the E1 error code of 70H01H, the E2 error code of 70H02H, and the E3 error code of 70H03H It is configured. In this specific example, the E1 error code is output when a ten-count abnormal error is detected and no game ball is detected when the special winning opening 40 is opened, and the E2 error code is full when the lower plate 23 is full. 43 is output when the switch is turned on, and the E3 error code is output when the supply switch 44 is turned on. The error message displayed by sending these abnormal time commands is deleted by the error release code of 70H04H that is sent when the abnormality is released.

  In each subsequent output process (step S60), as the game progresses, the main control board 30, the special symbol display device 32, the prize ball control board 31, the launch control board 33, the lamp control board 34, the sound control board 35, Output processing is executed for each of the various solenoids such as the prize opening solenoid 40c. That is, when it is detected by each input process (step S45) that there is a game ball winning at each winning port on the game board 22, a prize ball is given to the prize ball control board 31 so as to pay out the game ball as a prize ball. An error signal is sent to the symbol control board 32b to notify the fact that an error is occurring when the pachinko machine 10 is abnormal in the process of outputting data, the process of outputting sound data corresponding to the gaming state to the sound control board 35. The output process is further executed, and when a big hit occurs, the big hit process is executed.

  The remaining process subsequent to the above-described process is composed of an outlier symbol random number update process (step S65) and an initial random number update process (step S70), which are exactly the same as the above-described steps S20 and S35, respectively. These two processes form an infinite loop and are repeatedly executed as long as time is allowed until the next interrupt is executed. The time required for executing this processing from steps S10 to S60 described above differs for each interrupt depending on whether or not to execute the jackpot processing, the difference in the display mode of special symbols, and the like. As a result, the number of times the remaining process is executed is different for each interrupt, and the interrupted process shown in FIG. 5 is executed once, and the values to be updated (added) of the symbol random number and the initial random number are uniform. Disappear. Thereby, there is no possibility that the initial random number and the out-of-sequence random number are synchronized with the random number. In the present embodiment, the update of the random number is changed according to the value of the initial random number, so there is no possibility of synchronization. The normal symbol random number update process (step S40) described above may also be executed in the remaining process.

  The control executed by the prize ball control board 31, the lamp control board 34, the sound control board 35, etc. during the game has the same configuration as the conventional one, and the description thereof will be omitted.

(Probability of the first specific example and short-time processing)
Next, the probabilistic change and time reduction processing of the first specific example executed by the main control board 30 will be described with reference to FIGS. First, a subroutine for probability variation control will be described with reference to FIG. It is determined whether or not the display result of the special symbol variation is a big hit (S110). If it is a big hit in S110, it is next determined whether or not the big hit symbol is a probability variation symbol (S120). If it is determined in S120 that the symbol is a probability variation symbol, the probability variation flag J is set (S130), and the process returns to the return. On the other hand, if it is determined in S110 that the display result of the special symbol variation is not a big hit, or if it is determined in S120 that the symbol is a normal symbol other than the probability variation symbol, the process returns to the return as it is.

  Next, a subroutine of probability improvement period control 1 executed by the main control board 30 will be described with reference to FIG. First, it is determined whether or not the big hit operation has ended (S210). If it is determined in S210 that the big hit operation has ended, it is determined whether or not the probability variation flag J is set (S220). When the probability variation flag J is set, the big hit lottery is set to a high probability (S230). As a result, in the state where the probability of the big hit lottery is set to a high probability, the big hit lottery is performed in accordance with each variation operation of the special symbol. Next, it is determined whether or not the special symbol has fluctuated, that is, whether or not there is reserved storage, or whether or not the first type start port switch 36a is turned on (S240). If there is a reserved memory, or if the first type start port switch 36a is turned on, the special symbol is changed. When it is detected that the special symbol has changed in S240, the probability variation counter G indicating the number of probability variations is incremented by 1 and stored in the memory (S250), and the background screen 52 displays “the number of variations due to probability variation is G”. “Probability will be changed after XX times” is displayed and the player is informed of the number of special symbol variations (starting frequency) in the probability variation (S260). Subsequently, it is determined whether or not the probability variation counter G has reached 50 (S270). If the probability variation counter G does not reach 50 times, return to return. If it is determined in S270 that the probability variation counter G has reached 50 times, the probability variation operation is ended, so the probability variation flag J is reset (S280), the probability variation counter G is set to 0 (S290), and the big hit The lottery is set to a low probability (S295), and the process returns. If a negative determination is made in S210, S220, or S240, the process returns to the return.

  Next, a subroutine of the short time period control 1 executed by the main control board 30 will be described with reference to FIG. First, it is determined whether or not the big hit operation has ended (S310). If it is determined in S310 that the big hit operation has ended, it is determined whether or not the probability variation flag J is set (S320). If the probability variation flag J is set, the short time period flag K is set (S330), and the short time operation is performed (S340). The short time operation shortens the variation time of the special symbol to speed up the determination of the special symbol, and shortens the variation time of the normal symbol to increase the chance of winning the prize for the ordinary electric accessory 36. Next, it is determined whether or not the special symbol has fluctuated, that is, whether or not there is reserved storage, or whether or not the first type start port switch 36a is turned on (S350). If there is a reserved memory, or if the first type start port switch 36a is turned on, the special symbol is changed. If it is detected in S350 that the special symbol has changed, the hourly fluctuation counter H indicating the number of hourly fluctuations is incremented by +1 and stored in the memory (S360). “Time is later, XX times later” is displayed and the player is informed of the number of times the special symbol fluctuates during the time (starting frequency) (S370). Subsequently, it is determined whether or not the time-varying counter H has reached 100 times (S380). If the time variation counter H does not reach 100 times, the process returns. When the time variation counter H reaches 100 times, the time variation operation is stopped by resetting the time period flag K to stop the time variation operation in order to end the probability variation operation (S390), and set the time variation counter H to 0 (S395). Return to return. If a negative determination is made in S310, S320, or S350, the process returns to the return.

  An example of the probability variation control, the probability improvement period control 1 and the short time period control 1 will be described with reference to the time chart of FIG. In FIG. 12, first, when a jackpot symbol of a probability symbol is derived in each of the special symbol display areas 50a to 50c of the LCD 32a, a probability improvement period is generated along with this, and the variation of the special symbol is 50 times. The period continues and becomes a high probability state, and when it reaches 50 times, the period ends. On the other hand, with the start of the probability improvement period, a shortening period also occurs, and the period continues until the special symbol changes to 100 times, and the shortening operation is executed.

  In addition, when the big hit state is caused by the suspension of the special symbol within the probability improving period or the short time period, the big hit operation is prioritized, and the high probability operation and the short time operation executed during the period are also set as the stopped state. good. When a big hit is again made in the probability variation symbol during the probability improvement period or the short time period, the probability variation fluctuation counter G or the short time fluctuation counter H is reset, and it is advantageous to the player to be counted from the beginning after the big hit operation is completed. It can also be a process. In addition, when a big hit is made with a symbol that is not a probability variation symbol, the probability variation counter G and the hourly variation counter H can be continued for the remaining number of times after the big hit ends. It is also possible to be in the gaming state.

  As described above, in this specific example 1, when the jackpot movement with the probability variation pattern is finished, the provision of the probability variation control in the probability improvement period and the provision of the time reduction operation in the short time period longer than the probability improvement period are performed. Is going. For this reason, in the past, the probability change and time reduction ended at the same time, but in this embodiment, the time reduction period is set even after the probability improvement period ends, so the improvement of gambling is aimed at. Can do. In addition, the probability improvement period and the shortening period are both defined by the number of changes in the special symbol, and even if the jackpot is derived or continues to be derived for symbols other than the probability variation during the probability improvement period, the probability improvement period and the shortening period are There is an effect to be secured.

(Probability of the second specific example and short-time processing)
Next, the probability change and the time saving process of the second specific example executed by the main control board 30 will be described with reference to FIGS. Since the subroutine of the probability variation control in FIG. 9 and the subroutine of the probability improvement period control 1 in FIG. 10 are the same processing, they are used, and therefore, the subroutine of the short-term control 2 executed on the main control board 30 is illustrated. Explanation will be made with reference to FIG. First, it is determined whether or not the big hit operation has ended (S410). If it is determined in S410 that the big hit operation has ended, it is determined whether or not the probability variation flag J has changed from the set state to the reset state (S420). When the probability variation flag J is in the reset state, the short time period flag K is set (S430), and the short time operation is performed (S440). The short time operation shortens the variation time of the special symbol to speed up the determination of the special symbol, and shortens the variation time of the normal symbol to increase the chance of winning the prize for the ordinary electric accessory 36. Next, it is determined whether or not the special symbol has fluctuated, that is, whether or not there is reserved storage, or whether or not the first type start port switch 36a is turned on (S450). If there is a reserved memory, or if the first type start port switch 36a is turned on, the special symbol is changed. When it is detected in S450 that the special symbol has changed, the time fluctuation counter H is incremented by +1 and stored in the memory (S460), and the background screen 52 displays “the number of fluctuations due to time reduction is H”. “O.times.” Is displayed, and the player is notified of the number of special symbol changes (starting times) during the time reduction (S470). Subsequently, it is determined whether or not the time variation counter H has reached 50 times (S480). If the time variation counter H does not reach 50 times, the process returns. When the time variation counter H reaches 50 times, the time variation operation is stopped by resetting the time variation flag K to stop the time variation operation to end the probability variation operation (S490), and set the time variation counter H to 0 (S495). Return to return.

  An example of the probability variation control, the probability improvement period control, and the short time period control 2 will be described with reference to the time chart of FIG. In FIG. 14, first, when a jackpot symbol of a probability symbol is derived in each of the special symbol display areas 50a to 50c of the LCD 32a, a probability improvement period is generated accordingly, and the change until the special symbol changes to 50 times. The period continues and becomes a high probability state, and when it reaches 50 times, the period ends. On the other hand, as the time period ends, a time-shortening period occurs, and the time-shortening operation is executed until the special symbol changes to 50 times, and when the time becomes 50 times, the time-ending period ends.

  As described above, in this specific example 2, when the jackpot operation with the probability variation symbol is finished, first, the probability variation control in the probability improvement period is given, and after the probability improvement period, the time shortening operation in the predetermined short time period is given. Is done. For this reason, in the past, the probability change and time reduction ended at the same time, but in this embodiment, the time reduction period is set after the probability improvement period ends by shifting the time reduction period after the probability improvement period. Therefore, the enjoyment of time saving can be kept behind, the time reduction can be enjoyed following the probability improvement period, and the maintenance and improvement of gambling can be achieved. On the other hand, there is an effect that the profit can be secured because the short time period is regulated for the hall.

(Probability of 3rd specific example and time reduction processing)
Next, the probabilistic change and time reduction processing of the third specific example executed by the main control board 30 will be described with reference to FIGS. The subroutine for the probability variation control is the same as that shown in FIG. Next, a subroutine of probability improvement period control 3 executed by the main control board 30 will be described with reference to FIG. Since this process is generally the same as the probability improvement period control 1 of FIG. 10, the description of the common part is used, but the probability variation counter G is compared with 120 in S570.

  Next, the subroutine for the short time period control 3 executed by the main control board 30 will be described with reference to FIG. Since this process is substantially the same as the time-short period control 1 in FIG. 11, the description of the common part is used, but in S680, the time-variation counter H is within a predetermined range (the time-variation counter H is 30 to 60 or 90 to 120). If the determination is negative in S680, a step (S687) in which the time variation counter H is compared with 170 is added. Is different.

  An example of the probability variation control, the probability improvement period control 3 and the short time period control 3 will be described with reference to the time chart of FIG. In FIG. 17, first, when a jackpot symbol of a probability symbol is derived in each of the special symbol display areas 50a to 50c of the LCD 32a, a probability improvement period is generated along with this, until the variation of the special symbol reaches 120 times. The period continues and becomes a high probability state, and when it reaches 120 times, the period ends. On the other hand, with the start of the probability improvement period, a shortening period also occurs, the period continues until the special symbol changes to 30 times, and the shortening period is executed, and then the shortening period is stopped 30 times, The time reduction period is set again 30 times and the time reduction operation is executed. Also, the time reduction period is set 30 times again and the time reduction operation is stopped. At the same time as the probability change operation is completed, the time reduction period is set 50 times. The action is executed.

  As described above, in the third specific example, when the big hit operation with the probability variation pattern is finished, the probability variation control is given in the probability improvement period, and the intermittent time reduction operation is performed in the short time period longer than the probability improvement period. And granting. For this reason, in the past, the probability change and time reduction ended at the same time, but in this embodiment, the time reduction operation is intermittently performed even during the probability improvement period, and intermittently even after the probability improvement period ends. Since a short time period is set, it is possible to maintain and improve gambling. On the other hand, since the short time period is regulated intermittently for the hall, there is an effect that the profit can be secured.

(Probability of 4th specific example and time reduction processing)
Next, a description will be given with reference to the probabilistic change and time reduction processing of the fourth specific example executed by the main control board 30. This process is obtained by replacing the probability improvement period and the short time period of the first specific example, and the flowchart can be created by those skilled in the art from FIGS. 9 to 12, and therefore the description uses the first specific example.

  An example of the probability variation control, the probability improvement period control, and the short time period control will be described with reference to the time chart of FIG. In FIG. 18, first, when a jackpot symbol of a probability symbol is derived in each of the special symbol display areas 50a to 50c of the LCD 32a, a short time period is generated accordingly, and the period until the special symbol variation reaches 50 times. Continues and becomes a high probability state, and when it reaches 50 times, the period ends. On the other hand, with the start of a short time period, a probability improvement period also occurs, and this period continues until the special symbol changes to 100 times, and the probability improvement operation is executed.

  As described above, in the fourth specific example, when the big hit operation with the probability variation symbol is finished, the probability variation control is given in the short time period and the probability variation operation is given in the predetermined period longer than the short time period. Yes. For this reason, in the past, the probabilistic change and time reduction ended at the same time, but in this embodiment, since the probability improvement period is set even after the time reduction period ends, it is intended to maintain and improve gambling. Can do.

(Probability of the fifth specific example and short-time processing)
Next, a description will be given of the probability change and the time saving process of the fifth specific example executed by the main control board 30. This process replaces the probability improvement period and the short time period of the second specific example, and the flowchart can be created by those skilled in the art from FIGS. An example is cited.

  An example of the above-described probability variation control, probability improvement period control, and short time period control will be described with reference to the time chart of FIG. In FIG. 19, first, when a jackpot symbol of a probability symbol is derived in each of the special symbol display areas 50a to 50c of the LCD 32a, a short time period is generated in association with this, and the period until the variation of the special symbol reaches 50 times. Continues and becomes a high probability state, and when it reaches 50 times, the period ends. On the other hand, as the period ends, a probability improving period occurs, and the period continues until the special symbol changes to 50 times, and the probability increasing operation is executed, and when the number of times reaches 50, the period ends. To do.

  As described above, in the present specific example 5, when the big hit operation with the probability variation pattern is finished, first, the short-time operation in the short time period is given, and after the short-time period, the probability improving operation in the predetermined probability improvement period is given. Is done. For this reason, in the past, the probability change and the short time ended at the same time, but in this embodiment, the probability improvement period is set after the short time period ends by shifting the probability improvement period to the short time period. Therefore, the enjoyment of the probability variation can be kept behind, and the probability variation can be enjoyed continuously in a short time, so that the gambling can be maintained and improved. On the other hand, there is an effect that the profit can be secured because the probability improvement period is regulated for the hall.

(Probability of 6th specific example and short-time processing)
Next, a description will be given of the probability change and the time reduction processing of the sixth specific example executed by the main control board 30. This process replaces the probability improvement period and the short time period of the third specific example, and the flowchart can be created by those skilled in the art from FIG. 9, FIG. 15, and FIG. Three specific examples are cited.

  An example of the probability variation control, the probability improvement period control, and the short time period control will be described with reference to the time chart of FIG. In FIG. 20, first, when a jackpot symbol of a probability symbol is derived in each of the special symbol display areas 50a to 50c of the LCD 32a, a short time period is generated accordingly, and the period until the variation of the special symbol reaches 120 times. Is continued and a short time operation is performed, and the period ends when 120 times are reached. On the other hand, with the start of a short time period, a probability improvement period also occurs, the period continues until the special symbol changes to 30 times, and the jackpot lottery is set to a high probability, and then 30 times the probability improvement period Is stopped and the jackpot lottery is set to a low probability, again 30 times, the jackpot lottery is set to a high probability, and again 30 times, the probability improvement period is stopped and the jackpot lottery is set to a low probability, Simultaneously with the end, the probability improvement period is set 50 times, and the big hit lottery is set with a high probability.

  As described above, in the present specific example 6, when the big hit operation with the probability variation pattern is completed, the probability improvement period is intermittently set in the provision of the short time operation in the short time period and the period longer than the short time period. Therefore, the big hit lottery is set to a high probability state. For this reason, in the past, the probability change and time reduction ended at the same time, but in this embodiment, the probability improvement operation is intermittently performed even during the time reduction period, and the probability improvement period is increased even after the time reduction period ends. Since it is set, it is possible to maintain and improve euphoria. On the other hand, since the probability improvement period is regulated intermittently for the hall, there is an effect that the profit can be secured.

(Operation of this embodiment)
By executing the processes described above, the pachinko machine 10 performs the following operations.
That is, a game ball is launched onto the game board 22 by the launch motor 33a in accordance with the amount of rotation of the launch handle 24 operated by the player, and the fired game ball serves as a first electric starter 36 as a first type starting port. If it wins, it will be detected by the first type start port switch 36a, and the special symbols will be displayed on the LCD 32a screen of the special symbol display device 32 on the special symbol display areas 50a to 50c (see FIG. 6) for a predetermined time and then displayed statically. Work like that. A command or the like related to a symbol is transmitted from the main control board 30 to the symbol control board 32b. The symbol control board 32b determines reach occurrence as described above and displays an image such as a special symbol or a background symbol on the LCD 32a screen. As described above, image control is executed. As for the special symbol, the left symbol is first statically displayed, then the right symbol is statically displayed. If the right symbol and the left symbol do not match, the disengagement is confirmed, and then the middle symbol is statically displayed. When the right symbol and the left symbol coincide with each other (for example, 7-7), the reach is reached, and the middle symbol fluctuates and the still symbol is displayed. When the stationary middle symbol does not match the right and left symbols, the reach is lost (for example, 727). On the other hand, if the special symbol displayed statically is a specific symbol that has been determined in advance, for example, if all special symbols match after the reach (three-digit same symbol such as “777”), then a big hit state is displayed. Provide game contents advantageous to the player.
As described above, whether or not the big hit state is reached depends on whether or not the value of the random number that is determined when the game ball is detected by the first type start port switch 36a by the main control board 30 is a predetermined value. It is determined. Whether or not reach is determined by the symbol control board 32b is determined by whether or not the reach determination random number is a determination value.

  In this way, when the big hit state is reached, the big winning opening 40 is opened for about 30 seconds or until 10 seconds when the game is won by the count switch 40b, whichever comes first. When it is detected by the V switch 40a that the winning game ball has passed through the special area, the large winning opening 40 is once closed and then opened again, and this opening operation is repeated up to 16 times. Normally, 15 game balls are paid out as winning balls for one winning game ball, so when one big hit state occurs, about 2400 (= 15 × 10 × 16) A game ball can be obtained as a prize ball. This prize ball discharge operation is executed by the prize ball control board 31. The V solenoid 40d for opening and closing the special area of the special winning opening 40 is for closing the special area when one game ball passes through the special area. Thereafter, when the big hitting operation is finished, the probability changing operation and the time-shortening operation as described in the first to third specific examples are executed.

(Effect of this embodiment)
As described above, according to the present embodiment described in detail, by changing the period between the probability improvement period and the short time period, it is possible to realize a game with a structure that has not been conventionally achieved, and to improve the relationship between the probability improvement period and the short time period, The preference can be improved. Moreover, even after the end of the probability improvement period, the player is not bored by providing the privilege of the short time period, while the player is not bored by providing the privilege of the probability improvement period even after the end of the short time period. In addition, it is possible to avoid a situation in which the probability improvement period or the short-term period ends early, and it is possible to give the player a period advantageous to the player for a certain period or more, thereby providing the player with a sense of security. In addition, by using these periods as a reference for the number of changes in the special symbol, there is an effect that it is easy for the player to set an indication of the end of the period. Furthermore, by making the probability improvement period or short-term period intermittent, even if the player thinks that the probability improvement period or short-term period has ended, the period can be reinstated to increase the game's preference. effective. On the other hand, since the probability improvement period or the time period can be regulated for the hall, there is an effect that the profit can be secured.

  Note that the present invention is not limited to the specific examples described above, and it goes without saying that the present invention can be modified within the intended scope of the present invention. For example, in the embodiment described above, it is easier to start the normal electric utility 36 by shortening the normal symbol. However, other procedures such as increasing the probability of hitting the normal symbol during the shorter time. And the ordinary electric accessory 36 is opened a plurality of times for one start prize, the opening time is extended, or a combination thereof is included. Even in this case, the start winning is very likely to occur.

  In this embodiment, the special symbol is accelerated by shortening the special symbol, but other procedures may be used. For example, instead of sequentially stopping the special symbol, if the three symbols are stopped at the same time, Time can be shortened. Even if the reach action is abolished or the time is shortened, the time-saving effect can be realized. Note that if all of the special symbols under certain probability have no reach action, the display will be concise, and the next jackpot symbol can be quickly acquired. There are various types of probability fluctuation modes, such as the once-once type, the twice-time type, and the upper limit number regulation type (the maximum number of hits is limited even if the probability variation pattern is drawn again during probability variation). . Although the probability variation symbol of this embodiment also serves as a jackpot symbol, it may be set separately.
