Description

  The present invention relates to an electronic game machine incorporating a computer device, and is particularly suitably applied to a ball game machine and a spinning game machine.

  In a spinning machine such as a slot machine, when a player inserts a medal into a medal slot and operates a start lever, the rotation of the rotating reel is started accordingly. When the player presses the stop button to stop the rotating reel, when the symbols are aligned on an effective stop line (hereinafter referred to as an effective line), a payout medal corresponding to the symbol is paid out. However, in reality, the success / failure state of each game is determined in advance by the internal lottery process until the player starts the stop operation, and the symbol corresponding to the winning combination won by the lottery process is determined by the game. The payout medal is paid out when the person arranges them on the active line.

  The BB (Big Bonus) winning combination is particularly valuable as a winning combination. When the BB winning combination is won internally and the player aligns the corresponding BB symbols on the active line, the big bonus game is started, and thereafter, the winning probability of the small role symbol is maintained to be remarkably high. A large number of dividend medals can be expected.

  However, since the big bonus game has a high game value, the winning probability has to be set lower accordingly. Therefore, a winning combination other than the BB winning combination and a gaming state other than the big bonus game are also prepared so that the player can fully enjoy the player other than the big bonus game.

  For example, a game state called “replay time (RT)” is provided, and in the game during this replay time, the winning probability of the replay winning role that can start replaying without inserting a medal is increased from that in the general game. It is possible to suppress consumption.

  In this case, it is conceivable that a variety of games can be achieved by providing a plurality of types of replay times RT0 to RTn having different values for the player, such as a difference in the winning probability of the replay winning combination and the presence or absence of an assist function ( Patent Documents 1 to 3). Here, the assist function, for example, notifies the player of the stop order of the three rotating reels, and if the rotating reels are stopped in that order, the replay symbols corresponding to the internal winning replay winning combination must be aligned. It is a function that can be made to.

  As described above, in the slot machine, it is desired to enrich the game content. For example, instead of using one type of replay winning combination at each replay time (RT0 to RTn), a plurality of replay winning combinations are provided. It is conceivable to provide (RP1 to RPm). The game contents can be further enriched by providing a plurality of combinations of replay symbols (stop symbol modes) for realizing each replay winning combination (RP1 to RPm).

  FIG. 18 shows the contents of such a game, and n + 1 types of replay times (RT0 to RTn) are provided as gaming states, and a plurality of types of replay winning combinations during each replay time (RTi) are provided. (A, b,... X) are provided. In addition, a plurality of types of symbol patterns to be stopped on the active line in order to make each replay winning combination effective are defined for each replay winning combination.

  Therefore, for example, when the replay winning combination RP0a is internally won during the replay time (RT0), the stop symbol mode 05 (*-*-O) or the stop symbol mode 08 (O -*-○), ..., or any other stop symbol form 0k (○ -Δ- *) is aligned on the effective line, the replay winning combination RP0a is executed.

  In this way, while providing a plurality of types of replay times, and at each replay time, it is desirable to provide multiple types of winning combinations and multiple types of stopped symbols, on the other hand, in this type of gaming machine, Since the storage capacity of the memory for storing the data is legally limited, it is difficult to meet the above requirements. In general, the slot machine has a very short life cycle, and it is necessary to change the game performance one after another. Therefore, a configuration in which such a design change is easy is strongly desired.

  The present invention has been made in view of the above-described problems, and is capable of enriching gameplay without consuming the storage area of the memory, and having a configuration that can be easily changed in design. The purpose is to provide.

In order to achieve the above-mentioned object, the present invention defines a plurality of N types of lottery winning profits for a player in correspondence with a random value acquired based on a predetermined switch signal and N types of lottery winnings. A group of gaming machines that execute N success / failure determination processes that compare the determination value to be determined and determine a winning result for each lottery and have the same or similar benefits to the player As a lottery, a plurality of M types of specific lotteries are provided, and the number of specific lotteries that are not likely to win among a plurality of M types of specific lottery is appropriately changed as the game progresses. On the other hand, the determination table for storing the determination value including zero and the storage position of the determination value to be used in the determination process in the determination table are 1 byte or less corresponding to the lottery role to be determined in the determination process. Index value of Directly with specific lottery table, the provided propriety determination process M times for a particular lottery combination of a plurality M types, in the drawing table, by which the reference position is changed in response to a game progress, The determination value in the determination table is specified and executed for each specific lottery, and for a specific lottery that has no possibility of winning, it is possible to win by configuring the lottery table to use a zero determination value in the determination table. Regardless of whether there is an increase or decrease in a specific lottery combination, the processing contents of the determination process are made common.

  In the present invention, the process contents of the success / failure determination process are made common regardless of changes in game play and the like, so that the design change is easy. In addition, for example, the number of winning combinations that can be won can be increased or decreased according to the progress of the game, etc., so that the game can be enriched without wasting memory.

  It is preferable to limit the number of lottery winning combinations that can be won to N or less. The success / failure determination process of the present invention is executed in series using the random number value RND and the determination value Hit. However, as in the embodiment, the process of RND ← RND-Hit is repeated and RND <0 is selected. It is not always necessary to make it a condition. That is, instead of the operation of updating the random number value RND in the decreasing direction as in the embodiment, while updating the determination value Hit in the increasing direction (TO ← TO + Hit), in contrast to the random value RND, RND <TO It may be a winning condition. Further, the initial value (total value) is updated in a decreasing direction (TOTAL ← TOTAL−Hit) with the initial value ΣHit> RND as a condition and the total value TOTAL = ΣHit of the determination values as a condition (TOTAL ← TOTAL−Hit), and compared with the random value RND And it is good also considering RND> TOTAL as winning conditions.

  Regardless of which method is used, the determination processing for the determination value Hit = 0 is substantially skipped and is always in a lost state, so that the abundance of gaming can be realized without wasting memory. Can do. In addition, in the present invention, the number of winning combinations that can be won is suppressed to N or less, so that the game variation can be increased by appropriately changing the winning combinations that can be won as the game progresses. Can be made. Further, by increasing the determination value, it is possible to appropriately increase the winning probability of the necessary lottery combination.

  That is, according to the present invention, preferably, a group of lottery winnings having the same or similar profits to the player is provided, and the number of lottery winnings included in the group that are not likely to win is appropriately determined as the game progresses. Should be configured to change. In this case, it is more preferable that a lottery combination having no possibility of winning is always present regardless of the progress of the game.

  A lottery with no possibility of winning is selected as appropriate, but typically includes a replay lottery that can execute the next game without consuming game media. In this case, a plurality of M types of replay lottery combinations are provided as a group of lottery combinations, and the success / failure determination process is executed M times for each replay lottery combination. It is typically used in some of these. In addition, when any of the lotteries is won in the winning / failing determination process, this winning state is made effective on the condition that the symbols are arranged in a predetermined stop mode, and a prescribed profit is given to the player. In addition, it is preferable that a plurality of modes are provided as a stop mode for realizing the winning state of the replay lottery combination.

  The determination table is preferably divided into a byte table that stores a 1-byte length determination value and a word table that stores a 2-byte length determination value. In addition, a plurality of setting values that specify in stages the expected value of profit that can be enjoyed by the player are provided, and this setting value can be set by an attendant. A common table that stores a single determination value that is common regardless of the difference in the setting value, and a separate table that stores a group of determination values defined for each of the setting values for the same lottery combination It is also suitable.

  In the lottery table, combination information specifying a lottery combination to be determined in the determination process, table information specifying a determination table to be referred to in the determination process, and a determination value to be used in the determination process Are preferably stored in correspondence with the position information specified in the determination table specified by the table information, and the combination information, the table information, and the position information are 2 in total. More preferably, the length is less than or equal to the byte length.

  According to the above-described present invention, it is possible to realize a gaming machine having a configuration in which gameplay can be enriched without consuming the storage area of the memory and the design can be easily changed.

  FIG. 5 is a block diagram illustrating a circuit configuration of the slot machine SL according to the embodiment. As shown in the figure, this slot machine SL realizes an effect operation based on a main control board 50 that controls the operation of various game members including the rotating reels 4a to 4c and a control command received from the main control board 50. The control board 51 and a power supply board 62 that converts an alternating voltage (24V) into a direct voltage (5V, 12V, 24V) and supplies them to each part of the apparatus are mainly configured.

  The main control board 50 outputs, to the effect control board 51, control commands for realizing the sound effect by the speaker SP, the lamp effect by the LED lamp or the cold cathode ray tube discharge tube, and the symbol effect by the liquid crystal display unit 7. doing. The effect control board 51 is connected to the liquid crystal control board 61 through the effect interface board 52, and the liquid crystal control board 61 realizes a design effect in the liquid crystal display (LCD) unit 7.

  The effect control board 51 realizes lamp effects in various LEDs and cold cathode ray tube discharge tubes via the LED board 59, the inverter board 60, and the rotary LED drive board 58 together with the effect interface board 52. In addition, the effect control board 51 drives the speaker SP through the effect interface board 52 to realize an audio effect.

  The main control board 50 is connected to various game members of the slot machine through the game relay board 53. Specifically, the start switch of the start lever 17, the stop switch of the stop buttons 18a to 18c, the input switch of the input buttons 15 and 16, the liquidation switch of the checkout button 14, and the photointerrupters PH1 and PH2 constituting the input number determination unit 21d The blocker solenoid 31 constituting the inserted medal return unit 21c and the various LED elements 9 to 11 are connected.

  Further, the main control board 50 is connected to the three stepping motors for rotating the rotating reels 4a to 4c and the index sensor for detecting the reference position of the rotating reels 4a to 4c via the rotating relay board 57. Has been. Then, by rotating or stopping the stepping motor, the rotating operation of the rotating reels 4a to 4c and the stopping operation at the target position are realized.

  The main control board 50 is also connected to the medal payout device 5 through the payout relay board 63. The medal payout device 5 is provided with a medal payout control board 55, a medal payout sensor, and a payout motor M. The medal payout control board 55 is based on a control command from the main control board 50. Is rotated to pay out a predetermined amount of medals.

  In addition, the main control board 50 is also connected to the external concentration terminal board 56 and the rotary setting board 54. The external concentrated terminal board 56 is connected to, for example, the hall computer HC, and the main control board 50 outputs the number of inserted medals and the number of paid out medals through the external concentrated terminal board 56. Further, the rotating drum setting board 54 outputs a setting key signal indicating a setting value set by the staff using the setting key.

  Here, the set value defines the winning probability of the lottery process executed on the gaming machine in six stages from setting 1 to setting 6, and is appropriately set based on the sales strategy of the gaming hall. . For example, a gaming machine set to the highest rank is most advantageous to the player because the expected value of the number of medals to be paid out is the highest level.

  FIG. 6 illustrates the circuit configuration of the main control board 50. As shown in the figure, the main control board 50 includes a one-chip microcomputer 64, an I / O port circuit 65 for inputting / outputting 8-bit parallel data, a counter circuit 66 for generating random numbers in hardware, an effect control board 51, and the like. The interface circuit with the external board is mainly configured. Here, the one-chip microcomputer 64 incorporates a CTC (Counter / Timer Circuit) 64b, an interrupt controller 64c, and the like in addition to a Z80 equivalent CPU core 64a, ROM, RAM, and the like.

  The CTC 64b is a circuit in which an 8-bit counter and a timer are integrated, and adds a periodic interrupt, a pulse output creation function (bit rate generator) and a time measurement function to the Z80 system. Therefore, in this embodiment, a timer interrupt (FIG. 13A) is applied to the Z80 CPU 64a at a time interval τ of about 1.5 mS using the CTC 64b.

  As an interface circuit, an interface circuit 67 with a power supply circuit, an interface circuit 68 with a game relay board 53, a rotary motor driving circuit 69, an effect control board and an interface circuit 70 with 51 are provided. Yes. When the power is shut off, a voltage drop interrupt is applied to the Z80 CPU 64a through the interface circuit 67. Note that the rotating motor driving circuit 69 is a circuit that generates a driving signal for the stepping motors of the rotating reels 4 a to 4 c, and the interface circuit 70 is an 8-bit parallel port for outputting a control command to the effect control board 51. It is.

  FIG. 7 is a circuit diagram illustrating the counter circuit 66 in more detail. The counter circuit 66 shown in the figure includes an input unit 24 that receives a start switch signal SG indicating ON operation of the start lever 17, a signal acquisition unit 25 by two D-type flip-flops 25a and 25b, and the lower 8 bits of hardware random numbers ( LOW) and an IC counter 26H that generates upper 8 bits (HI) of hardware random numbers. The output terminals (QA to QH) of the IC counters 26H and 26L are connected to the one-chip microcomputer 64 (CPU core 64a) through a data bus.

  The input unit 24 includes a low-pass filter including a resistor and a capacitor, and a Schmitt trigger type inverter. Therefore, the negative logic start switch signal SG is logically converted and supplied to the signal acquisition unit 25.

  The signal acquisition unit 25 includes two D-type flip-flops 25a and 25b connected in series. A reference pulse Φ is supplied to each clock terminal CLK, and data at the D input terminal is acquired and output to the Q output terminal at the timing of the rising edge of the reference pulse Φ. Therefore, after the start switch signal SG changes to the L level, the lock terminals RCLK of the IC counters 26L and 26H rise to the H level at the rising edge of the second reference pulse Φ.

  The reference pulse Φ is preferably oscillated separately from the system clock by a dedicated oscillation circuit, but for simplicity, a system clock for operating the one-chip microcomputer 64 may be substituted for the reference pulse Φ.

  Each of the two IC counters 26 includes an 8-bit binary counter and an 8-bit output register. When the clock signal supplied to the clock terminal CCLK is binary counted, when the holding signal is received at the lock terminal RCLK, the counter value of the binary counter at that moment is stored in the built-in output register. Yes. The counter value stored in the output register is output to the external output terminals (QA to QH) on condition that the output enable terminal OE is at the L level.

  As illustrated, in the counter circuit 66, as long as the power supply voltage value (DC5V) is a normal value, the reference pulse Φ is supplied to the clock terminal CCLK of the lower IC counter 26L via the NAND gate. On the other hand, the carry signal RCO of the lower IC counter 26L is supplied to the upper IC counter 26H. Therefore, the two IC counters 26 function as a 16-bit counter as a whole, and the two internal counters circulate between 0000H to FFFFH (decimal number 65535) counter values. The subscript H means a hexadecimal number including the following cases.

  As described above, when the start switch signal SG changes to L level, the lock terminal RCLK of each IC counter 26L, 26H rises to H level correspondingly, and the value of the internal binary counter is held in the output register. Is done. On the other hand, chip select signals CS0 and CS1 are supplied from the one-chip microcomputer 64 to the output enable terminals OE of the IC counters 26L and 26H. Therefore, the one-chip microcomputer 64 can acquire the data QA to QH held in the output registers built in the IC counters 26L and 26H by changing the chip select signals CS0 and CS1 to L level when necessary.

  FIG. 8 is a block diagram showing a circuit configuration of the power supply board 62. The power supply board 62 includes a rectifying unit 80 that receives AC 24V and converts it into a pulsating voltage, a first voltage converting unit 81 that converts the pulsating voltage into DC 5V, and a second that converts the pulsating voltage into DC 12V. A voltage conversion unit 82; a third voltage conversion unit 83 that converts the pulsating voltage into 24V DC; a power storage unit 84 that stores the output voltage of the first voltage conversion unit 81; And a power supply monitoring unit 85 that outputs

  The power storage unit 84 includes a capacitor C having a large capacity (about 1 Farad), limiting resistors r1 and r2 for overcurrent, and a diode D that blocks reverse current. The limiting resistance r1 is about 75Ω, and the limiting resistance r2 is about 10Ω. The voltage across the capacitor C is supplied to the one-chip microcomputer 64 as a backup power source.

  This backup power is supplied to an SRAM (static ram) built in the one-chip microcomputer 64, and even if the power supply voltage is cut off, the stored contents of the RAM (Random Access Memory) are usually held for 7 to 8 days. I have to. In this embodiment, the storage capacity of the RAM is about 512 bytes used as a work area for the gaming machine.

  The power supply monitoring unit 85 monitors the voltage level of the AC input voltage 24V and the voltage level of the DC power supply voltage 5V. Then, when any one level falls below a predetermined value, the detection signal RES changes to the L level. When an abnormality such as a momentary power failure or a power failure occurs, first, the detection signal RES is quickly output in response to the voltage drop of the AC input voltage.

  This detection signal RES is supplied to the interface circuit 67 (FIG. 6) of the main control board 50, and becomes a positive logic abnormality signal ALM and a negative logic abnormality signal ALM bar. A positive logic abnormality signal ALM is supplied to the I / O port circuit 65, while a negative logic abnormality signal ALM bar is supplied to an interrupt terminal INT (maskable Interrupt) of the one-chip microcomputer 64. Therefore, at this time, if the CPU core 64a is in the interrupt enabled state, the voltage drop interrupt process is started based on the negative logic abnormality signal ALM bar.

  The interface circuit 67 in FIG. 6 also includes a power reset circuit. When the power is turned on, the reset signal generated by the interface circuit 67 is supplied to the reset terminal RST0 of the one-chip microcomputer 64. As a result, the CPU core 64a is reset, and execution of the control program after the head address of the ROM is started.

  Next, the control operation realized by the one-chip microcomputer 64 (hereinafter referred to as the main control unit 50) of the main control board 50 will be described. 9 to 11 are flowcharts for explaining a control program executed by the main control unit 50. The control program of the main control unit 50 includes an infinite loop main process (FIG. 9 (a)) started when the power is turned on, a timer interrupt process (FIG. 9 (b)) started by a scheduled interrupt from the CTC, , And a voltage drop interrupt process (not shown) that is activated by a detection signal RES from the power supply board 62 when the power is shut off. Here, the timer interrupt and the voltage drop interrupt are both maskable interrupts, and the interrupt period τ of the timer interrupt is about 1.5 mS.

  First, the main process of FIG. 9A will be described. When the power is turned on, after the initial process (ST1), the CPU is set in the interrupt enabled state and the work area of the RAM is cleared (ST2).

  When the process of step ST2 is completed, the medal insertion process for the medal actually inserted from the medal insertion slot 12 and the medal actually inserted by pressing the insertion buttons 15 and 16 is performed (ST3). . In the medal insertion process (ST3), a medal inserted or pseudo inserted by the player is detected, the number of inserted medals is determined, and when the start lever 17 is turned on, the subroutine process is terminated. As described with reference to FIG. 7, when the start lever 17 is turned ON, the start switch signal SG changes to the L level, and the counter value at that moment is stored in the output register built in each IC counter 26H, 26L. It is retained and stored (see FIG. 7).

  Therefore, the random number acquisition process (ST4) is executed following the medal insertion process (ST3). Specifically, the one-chip microcomputer 64 changes the chip select signals CS0 and CS1 to the L level, acquires the counter value held in the counter circuit 66, and obtains the random value RND (numerical range: 0). ~ 65535) is stored in the corresponding address of the RAM.

<Internal lottery process (ST5)>
Next, based on the stored random number value RND, an internal lottery process for determining whether or not a small role winning state or a bonus winning state is performed is executed (ST5). The detailed operation of the internal lottery process will be described in detail. In summary, the determination value Hit defined for each of the 92 types of lottery is sequentially subtracted from the random value RND acquired in the process of step ST4 ( RND ← RND-Hit), when RND <0, it is determined that the lottery is won (see ST64 to ST65 in FIG. 10). Therefore, when the random number value RND is smaller than the total addition value ΣHit of the determination value Hit, a certain winning state is surely obtained, and when the random number value RND is larger than the total addition value ΣHit of the determination value, the lottery role is removed. It will be.

  By the way, in this embodiment, there are general-purpose 50 types shown in FIG. 11 (a) as small role winning combinations, and 4 types (BB1 winning combination and BB2 winning combinations shown in FIG. 11 (b) as bonus winning combinations. Role, RB1 winning combination, RB2 winning combination). In this embodiment, the control program and the memory structure can be changed even if the game characteristics are changed for each type of gaming machine by changing the type and number of the small role winning combinations and the winning probability of each small role winning combination. The maximum memory that can be used as a data area is secured.

  Therefore, not all of the small role winning combinations and bonus winning combinations shown in FIG. 11A and FIG. 11B are necessarily used in all models. For example, in this embodiment, 50 types Among the small role winning roles, the Cherry D winning role and the Cherry E winning role are not used, and there are 48 types of small role winning roles that are actually used.

  Aside from such a small difference for each model, the gaming state of the gaming machine is roughly divided into a bonus gaming state and a general gaming state other than that, and in the general gaming state of this embodiment, internal lottery processing (ST5) The lottery table LOT1 shown in FIGS. 12 to 13 is used. The general gaming state is further subdivided into four gaming states (replay time RT0 to replay time RT3) having different winning probabilities for the replay winning combination.

  Here, when evaluated by the winning probability for the replay winning role, a game such as low probability replay time RT0 (initial state) → low probability replay time RT1 → medium probability replay time RT3 → high probability replay time RT2. It is configured to be promoted in order with progress (see FIG. 17). However, if the luck is bad, the replay time RT2 with a high probability falls from the replay time RT1 with a low probability (see FIG. 17).

  On the other hand, the bonus game state is subdivided into a BB (Big Bonus) game state and an RB (Regular Bonus) game state, and a lottery table LOT2a for BB shown in FIGS. 13 (b) and 13 (c), respectively. The lottery table LOT2b for RB is used. Each of the lottery tables LOT2a and LOT2b is set so that the winning probability for the small role winning combination is set to be significantly higher than the lottery table LOT1 used in the general gaming state, and the player can acquire a large number of medals. Yes.

<Structure of lottery table LOT1>
The lottery tables LOT1 used in the general gaming state are as shown in FIGS. 12 to 13, and a total of 92 types of lottery are obtained by appropriately combining 48 types of small role winning combinations and 4 types of bonus winning combinations. A role is provided. When specifically confirmed, the lottery 1 to lottery 46 shown in FIG. 12 means a single lottery for a small role winning role excluding “Cherry C Winner” and “Chance D Winner”. Yes. Accordingly, in this embodiment, the small role winning combination of “Cherry C winning combination” and “Chance D winning combination” is not won by itself.

  On the other hand, a lottery role 47 to a lottery role 88 shown in FIG. 13 are combined lottery roles of a small role winning role and a bonus winning role, and as shown in the lottery role 52 and the lottery role 58, The “chance D winning combination” is set to be able to win in combination with the bonus winning combination BB1. It should be noted that the lottery combination 89 to the lottery combination 92 mean a single lottery combination for the bonus winning combination (BB1, BB2, RB1, RB2).

  In the present embodiment, the total number 92 of the lottery roles configured in this way is the determination process of the right / fail determination process that compares the determination value Hit specified by the lottery table LOT1 with the random value RND acquired in the process of step ST4. In the internal lottery process (ST5), it is determined whether any of the 92 winning / rejecting determination processes results in an internal winning state, or whether all the 92 winning / rejecting determination processes are excluded.

  Based on the above, the data structure of the lottery table LOT1 used in the general gaming state (in general gaming) will be described with reference to FIG. In the lottery table LOT1 shown in FIGS. 12 to 13, among the total of 92 lottery combinations, 81 excluding 11 types of replay winning combinations (lottery combinations 1 to 11) are shown in FIG. 11C. A determination value Hit that is 2 bytes long and should be used in the validity determination process is specified. On the other hand, 11 types of replay winning combinations RP1 to RP11 (lottery combinations 1 to 11) specify the determination value Hit with a total length of 4 bytes, corresponding to the four types of gaming states (replay times RT0 to RT3). ing.

  As shown in FIG. 11 (c), the lower 6 bits (D5 to D0) of the first byte constituting each column (2 byte length or 4 byte length) of the lottery table LOT1 indicate information on the small role winning combination. Specifically, based on the 6 bits, the small combination winning combination to be a lottery target is specified. That is, any of the 50 types of small role winning combinations shown in FIG. 11A is specified based on the lower 6 bits (D5 to D0) of the first byte.

  On the other hand, the lower 3 bits (D2 to D0) of the second byte of each column of the lottery table LOT1 indicate information about the bonus winning combination, and specifically, the lottery table is targeted for lottery based on the 3 bits. A bonus winning combination (BB1, BB2, RB1, RB2) is specified. For the bonus winning combination as a single lottery combination, the lower 6 bits of the first byte specifying the small combination winning combination are set to zero. This is the same for the small role winning combination as a single lottery combination, and the lower 3 bits of the second byte for specifying the bonus winning combination are set to zero.

  However, in this embodiment, not only a small role winning combination as a single lottery combination and a bonus winning combination as a single lottery combination but also a combined lottery combination combining a small role winning combination and a bonus winning combination is provided. In such a composite lottery combination, significant data is defined in the lower 6 bits (D5 to D0) of the first byte and the lower 3 bits (D2 to D0) of the second byte. For example, in the field of the lottery combination 88 of the lottery table LOT1, the lower 6 bits (D5 to D0) of the first byte specify the “chance C winning combination” that is the small role winning combination, and the lower byte of the second byte. Three bits (D2 to D0) specify “RB2 winning combination” which is a bonus winning combination.

  By the way, the upper 2 bits (D7, D6) of the first byte of each field of the lottery table LOT1 store a determination value Hit used in the determination process of the lottery (any one of the lottery 1 to 92). The determination table TBL (ALB / ALW / RKB / RKW) is specified.

  Here, the determination table TBL according to the present embodiment is roughly classified according to whether or not the determination value Hit is different for each set value set by the staff before starting the business. In this embodiment, the winning probability and others of the internal lottery process are divided into six categories based on the set values set by the staff.

  The determination table TBL is further subdivided depending on whether a 1-byte length determination value (byte determination value) is stored or a 2-byte length determination value (word determination value) is stored. Since the determination value Hit defines the winning probability for the lottery, the lottery that is determined to be successful by the word determination value generally has a higher probability of winning than the lottery that is determined to be successful by the byte determination value. It will be.

  16 to 17 exemplify the four types of determination tables divided as described above. That is, FIG. 16 shows a “common BYTE determination table ALB” (FIG. 16A) that stores a byte determination value Hit that is used in common regardless of the setting value, and a common use regardless of the setting value. “Common WORD determination table ALW” (FIG. 16B) that stores the word determination value Hit to be performed is shown.

  Also, FIG. 17 shows “a set difference BYTE determination table RKB” (FIG. 17A) for storing the byte determination value Hit for each set value, and “a set difference for storing the word determination value Hit for each set value. “WORD determination table RKW” (FIG. 16B) is shown.

  As shown in FIG. 11 (c), the upper 5 bits (D7 to D3) of the second byte of each column of the lottery table LOT1 are indexes that specify the storage position of the determination value Hit in the determination table divided into four types. It means the value INDX. Therefore, for example, in the success / failure determination for the “AT27 winning combination” of the single lottery combination 38, the + 0th determination value (= 624) from the top in the “common WORD determination table ALW” shown in FIG. 16B is used. Will be. Further, for example, in the determination of whether or not “Bell winning combination” + “BB1 winning combination” of the composite lottery combination 49 is made, the + 6th determination value from the top in the “common BYTE determination table ALB” shown in FIG. = 2) will be used.

  As described above, the first byte and the second byte have been described for each column of the lottery table LOT1, but for the 11 types of replay winning combinations RP1 to RP11 (single lottery combinations 1 to 11), four types of gaming states ( Corresponding to the replay times RT0 to RT3), there are a third byte and a fourth byte.

  The contents of the third byte and the fourth byte are the same as the upper 5 bits (D7 to D3) of the second byte, and an index for specifying the storage position of the determination value Hit in each gaming state (replay time RT1 to RT3). The value INDX is stored. Therefore, for example, in the success / failure determination for the “RP1 winning combination” of the single lottery combination 1, the + 6th determination value from the top in the “common WORD determination table ALW” is used at the replay time RT0, and at the replay time RT1, The + 8th determination value from the top is used, the + 6th determination value from the top is used at the replay time RT2, and the + 11th determination value from the top is used at the replay time RT3.

<Configuration of lottery table LOT2>
The lottery table LOT1 used in the general gaming state has been described above. The lottery tables LOT2a and LOT2b used in the bonus gaming state are as shown in FIGS. 13 (b) and 13 (c). In the internal lottery process in the bonus game state, the bonus winning combination does not exist and the small role winning combination shown in the figure wins with high probability, so the lower 3 bits (D2 to D0) of the second byte of the lottery table LOT2 are not yet stored. It becomes use. However, other configurations are the same as those in the lottery table LOT1, and the upper 2 bits (D7 to D6) of the first byte are table identifiers that define one of ALB / ALW / RKB / RKW, and the lower 6 Bits (D5 to D0) specify the small role winning combination. However, in this embodiment, all table identifiers specify “common WORD determination table ALW” (see FIGS. 13B and 13C).

  The upper 5 bits of the second byte of the lottery table LOT2 specify the storage position of the determination value Hit in the “common WORD determination table ALW” specified by the table identifier.

<Replay winner>
By the way, for example, as in the stop symbol mode [Bell symbol-Bell symbol-Bell symbol] for effecting the internal winning state of the “Bell winning symbol” If there is a one-to-one correspondence, there is a risk that the game will become monotonous. Therefore, in this embodiment, the game characteristics are diversified by making the winning combination and the stop symbol form correspond to 1 to N. For example, in the replay winning combinations RP1 to RP11, the winning combination and the stop symbol form are associated with 1 to N, and as shown in FIG. The game contents are enriched by providing a variety of design modes.

  Here, the replay winning combinations RP1 to RP11 are winning combinations that can execute the next game without consuming medals, and each winning combination RP1 to RP11 corresponds to the stop symbol form shown in FIG. ing. As shown in the figure, for example, when the internal winning of the replay winning combination RP1 is made, (1) [Replay symbol R1-Replay symbol R1-Replay symbol R1] is stopped on the effective line, or (2) [Replay symbol R1- Either replay symbol R1-replay symbol R2] is stopped on the effective line, (3) [replay symbol R2-replay symbol R1-replay symbol R1] is stopped on the effective line, or (4) [replay symbol R2-replay symbol] If R1-replay symbol R2] can be stopped at the active line, the replay winning combination RP1 in the internal winning state is activated.

  Similarly, for example, when an internal winning is made for the replay winning combination RP11, (1) [Bell Symbol-Replay Symbol R1-Replay Symbol R1] is stopped at the active line, or (2) [Bell Symbol R1-Replay Symbol] If R1-replay symbol R2] is stopped on the active line or (3) [Red 7 symbol-Replay symbol R1-Red 7 symbol] can be stopped on the effective line, the replay winning combination RP11 in the internal winning state is effective. Will be converted.

  Also, in this embodiment, in order to enrich the game variations, the 11 types of replay winning combinations (RP1 to RP11) are not allowed to be regularly won internally, but (a) which replay winning combinations are internal There are provided a plurality of types of game states (replay times RT0 to RT3) that differ depending on whether winning is possible or (b) how much the winning probability is internal.

  FIG. 17 shows four types of replay times RT0 to RT3, a replay winning combination that can be internally won during each replay time, and a stop symbol form for making it effective when each replay winning combination is won internally. The relationship is illustrated. Note that the description in FIG. 17 is merely an example, and can be changed as appropriate.

  In the configuration shown in FIG. 17, after the power is turned on or after the bonus game is finished, the game state is automatically set at the replay time RT0, and only one type of replay winning combination RP10 can be won internally. The winning probability of the replay winning combination RP10 is also set to a low probability that is appropriately low. When the replay winning combination RP10 is won internally, [Replay symbol R1-Replay symbol R1-Bell symbol], [Replay symbol R2-Replay symbol R1-Bell symbol], [Bell symbol-Replay symbol R1-Bell symbol] ] And [Red 7 symbol-Replay symbol R1-Watermelon symbol] When the stop symbols are aligned on the active line, the replay winning combination RP10 is activated (see FIG. 16) and consumes medals. The next game can be started without it.

  In such a gaming state (RT0), when the replay winning combination RP10 is activated in a predetermined stop symbol form (for example, [bell symbol-replay symbol R1-bell symbol]), thereafter, the gaming state of the replay time RT1 Migrate to In the gaming state at the replay time RT1, in addition to the replay winning combination RP10, the replay winning combinations RP1 to RP6 are also set to be able to win internally. However, the winning probability of internally winning any of the replay winning combinations is almost the same as in the case of the replay time RT0, and the winning probability is set to a low probability. In addition, when the internal winning is made in any of the seven types of replay winning combinations, the stop symbol form for effecting this is as shown in FIG.

  In this embodiment, in the gaming state of the replay time RT1, any replay winning combination (RP1 to RP6 + RP10) is activated in a predetermined stop symbol form (for example, [bell symbol-replay symbol R1-bell symbol]). Then, the game state is changed to the replay time RT3. In the gaming state of the replay time RT3 that has been transferred, eight types of replay winning combinations (RP1 to RP6 + RP10 + RP11) are set to be able to win internally, and the winning probability of winning internally for any of the replay winning combinations is from the replay time RT1 so far , Set slightly higher (medium probability). In addition, when an internal winning is made for any of the eight types of replay winning combinations, a stop symbol form for effecting this is as shown in FIG.

  Then, in the game state of the replay time RT3, the replay winning combination RP3 or RP11 is internally won and the replay winning is performed in a predetermined stop symbol form (for example, [Red 7 symbol-Replay symbol R1-Red 7 symbol]). When the combination (RP11) is activated, the game state is promoted to a game state with a replay time RT2.

  In the gaming state at the replay time RT2, in addition to the replay winning combination (RP11), three types of replay winning combinations (RP7 to RP9) that have not appeared until then are set to be able to win internally. Then, the winning probability of internally winning any of the replay winning combinations (RP7 to RP9 + RP10) is set to a high probability that is significantly higher than the replay time RT3 so far. Therefore, the player obtains a profit that can greatly reduce the consumption of medals.

  However, in such a game state with the replay time RT2, if the replay winning combination (RP7) is activated in a predetermined stop symbol form (for example, [Replay symbol R2-Replay symbol R1-Replay symbol R2]). Thereafter, the game state falls to the replay time RT1 gaming state. Therefore, after that, the winning probability of internally winning one of the replay winning combinations (RP1 to RP6 + RP10) is low, and the consumption of medals cannot be suppressed much.

  Therefore, the player performs a game operation in the hope that the game state at the replay time RT1 can be shifted to the game state at the replay time RT3. In this embodiment, in order to facilitate the game state transition (RT1 → RT3) and the promotion of the game state (RT3 → RT2) described above, in this embodiment, when the internal winning is performed for some replay winning combination, An assist function that notifies the correct pushing order of the reels is exhibited. When this assist function is exhibited, following the notification content, the replay winning combination in the internal winning state is made effective, and the gaming state can be changed and the gaming state can be promoted.

<Judgment value sharing and non-use judgment values>
As described above, in this embodiment, a large number of small winning combinations including various replay winning combinations (RP1 to RP11) are used as a single lottery and / or a combined lottery. And in order to change the game characteristics for each type of gaming machine, the winning combination of small roles (single lottery + combined lottery) and bonus winning combination is increased or decreased as appropriate, and the winning rate of each winning combination is changed accordingly There is a need to. In such a case, with a conventional device configuration, it is necessary to redesign from scratch, which is very complicated and takes a very long time to complete the device. There is also a tendency to waste memory for diversifying game play.

  Therefore, in this embodiment, first, (a) it is not necessary to change the data structure even if the winning combination is changed, and (b) in order to facilitate the change of the winning rate for each winning combination, For a winning combination that is not used in practice, the determination value is set to zero, thereby making it unnecessary to change the data structure of the lottery table.

  Specifically, the winning combinations not used in this embodiment are (1) Replay winning combinations RP1 to RP9 and RP11 at the replay time RT0, (2) Replay winning combinations RP7 to RP9 and RP11 at the replay time RT1, (3 ) Replay winning roles RP1 to RP6 and RP11 at the replay time RT2, and (4) Replay winning roles RP7 to RP9 at the replay time RT3.

  For these winning combinations, the internal lottery process is executed in the same procedure as other winning combinations. However, since the determination value Hit is zero, the winning combination does not actually exist. That is, for the replay winning combination of (1) to (4) described above, the table identifier specifies “common BYTE determination table ALB” (FIG. 16A) and the index IND is 6, (1) Since zero is stored in the sixth of the “common BYTE determination table ALB” referred to in the replay winning combination determination process of (4) to (4), the determination process (ST64 to ST65) is substantially skipped. The A program configuration that skips the determination process (ST64 to ST65) based on the zero determination value Hit may be used. However, in such a configuration, the program area of the memory is consumed. In order to avoid wasting memory, useless determination processing (ST64 to ST65) is intentionally executed.

  As described above, in this embodiment, since the determination value Hit is set to zero for the winning combination that is not used, the data structure of the lottery tables shown in FIGS. 12 to 13 and the determination tables of FIGS. The design change is extremely easy. Further, by matching all the index values INDX of the replay time RT2 and the replay time RT3, a gaming machine having only the replay times RT0 to RT2 having no replay time RT3 without changing the data structure of the lottery table LOT or the determination table. Can also be configured.

  Further, in this embodiment, the judgment table (ALB / ALW) of FIG. 14 that is commonly referred to regardless of the setting difference of the six sections is always stored with different judgment values, thereby eliminating the waste of memory. doing. However, since it is necessary to use the same determination value in the design of the winning probability, in such a case, the lottery table LOT1 is configured to refer to the same table.

  Specifically, the + 2nd and + 5th to + 15th determination values Hit (= 2 and 5) of the “common BYTE determination table ALB” are shared in the determination process of the winning combination of a plurality of winning combinations. , Suppresses memory consumption. Further, the + 0th determination value Hit (= 624) of the “common WORD determination table ALW” is also used in common in the determination processing of the winning combinations (AT1 to AT27).

  In the present embodiment, by configuring in this way, it is possible to appropriately increase the type of winning combination without increasing the capacity of the determination table. Note that the determination table (RKB / RKW) in FIG. 15 has some of the determination values in common because of a request for gameability corresponding to the setting difference. In the above, the determination value for each setting is shared to suppress memory consumption.

  The lottery table LOT (FIGS. 12 to 13) and the determination table TBL (FIGS. 14 to 15) have been described above, and the internal lottery process (ST5) will be described in a confirming manner based on this point.

  As shown in FIG. 10, in the internal lottery process, first, the gaming state at that timing is grasped (ST51). As described above, the gaming state is roughly divided into a general gaming state and a bonus gaming state (BB / RB), and the general gaming state (in general gaming) is further divided into gaming states with replay times RT0 to RT3. ing.

  And the lottery table LOT which should be referred based on the specified game state is selected. If it is during a general game, the lottery table LOT1 of FIGS. 12 to 13 is selected, and if it is a bonus game state, the lottery table LOT2a of FIG. The lottery table LOT2b in FIG. 13C is selected.

  Next, an appropriateness determination process for comparing the random value RND acquired in the process of step ST4 with the determination value Hit specified in the lottery table is executed (ST53). In the success / failure determination process (ST53), first, the number of determinations of success / failure according to the gaming state is initialized in the B register of the Z80 CPU (ST60). As shown in the lottery tables of FIGS. 12 to 13, the number of hit / failure determinations is 92 when the timing is in the general gaming state (in general gaming), and three times in the bonus gaming state (in bonus gaming). It is.

  Subsequently, the lower 6 bits of the first byte and the lower 3 bits of the second byte are acquired from the corresponding column specified by the B register in the lottery table LOT specified by the gaming state grasped in the process of step ST51. The lottery role that is the object of the determination is determined (ST61). As described above, the lottery numbers 1 to 46 shown in FIG. 12 are single lotteries for the small role winning combination, and the lottery numbers 47 to 88 shown in FIG. 13 are the combined lottery of the small role winning combination and the bonus winning combination. A lottery number 89 to 92 shown in FIG. 13 is a single lottery for a bonus winning combination.

  Next, in the lottery table LOT specified by the gaming state, the upper 2 bits (table identifier) of the first byte and the upper 5 bits (table index INDX) of the second byte are selected from the corresponding column specified by the B register. Obtain (ST62). Then, in the lottery table TBL specified by the table identifier (ALB / ALW / RKB / RKW), the determination value Hit specified by the table index INDX is acquired (ST63).

  Thereafter, the determination value Hit is subtracted from the random value RND to update the value of the random value RND (ST64), and it is determined whether or not the updated random value RND is negative (ST65). Here, when RND <0, it means that the lottery role specified in step ST61 has been won in this determination. Therefore, when RND <0, the winning lottery is selected based on the B register, the winning number is stored, and the process ends (ST68).

  On the other hand, when the random number value RND after the process of step ST64 is ≧ 0, the B register is decremented (ST66), and the processes of steps ST61 to ST66 are repeated until the B register after the decrement becomes zero (STEP). ST67).

  If RND <0 by the above iterative process, the winning lottery that has been won is specified based on the B register, the winning number is stored, and the process is completed. However, if RND <0 is not reached until the end , Remember that it was out of all the lottery, and finish the process.

  As described above, the internal lottery process has been described based on FIG. 10, and the subsequent process will be described with reference to FIG. When the internal lottery process (ST5) with the random number value RND is completed, next, preparation work for rotating the rotating reels 4a to 4c is performed, and the rotation control of the rotating reels 4a to 4c by the timer interruption is enabled (ST6 to ST8). Thereafter, when the stop buttons 18a to 18c are pressed, a rotating cylinder stop process for stopping the corresponding rotating reels 4a to 4c is performed (ST8).

  In this spinning cylinder stop process, stop control is executed so as to follow the result of the internal lottery process (ST5). That is, as a result of the internal lottery process (ST5), if there is any internal winning state, the symbols of the rotating reels 4a to 4c are aligned so as to match the winning result on condition that the player performs an appropriate stop operation. However, if the timing at which the player presses the stop button or the order of the stop operation is inappropriate, the player is stopped in a lost state pattern. As a result, the small winning combination at the corner is wasted, but the bonus winning is carried over after the next game.

  When all the rotating reels 4a to 4c are stopped in this way, it is determined whether or not the winning symbols are aligned on the effective line (ST9), and the required number of medals are paid out (ST10).

  Then, a necessary process is executed by managing the game digest number of RT (replay time) (ST11). Next, it is determined whether or not the player is in the replay winning state (ST12). If the player is in the replay winning state, a re-game operation start process (ST15) is executed, and then the process proceeds to step ST2. Note that, as described above, there are multiple types of symbol combinations that are in the replay winning state.

  If it is not in the replay winning state, it is determined whether or not the bonus game is currently in progress (RB1 is in operation or RB2 is in operation). If the bonus game is in progress, the corresponding processing is executed and the process proceeds to step ST2.

  On the other hand, if the determination in step ST13 is NO, it is determined whether or not the bonus symbol is aligned (ST14). If the bonus symbol is aligned, the bonus game start process (ST17) is executed. The process proceeds to step ST2. There are many types of combinations of bonus symbols.

<Timer interrupt processing>
Next, the timer interrupt process shown in FIG. 9B will be described. This timer interrupt process is started at a constant time interval τ based on a maskable interrupt signal (timer signal) from the CTC inside the one-chip microcomputer 64.

  When a timer interruption occurs, the CPU register is saved (ST21), and then port input processing is performed (ST22). In the port input process, signals from all switches arranged in the slot machine, such as a start switch, a stop switch, a stored medal switch, a clearing switch, and a door switch, are input through the I / O port circuit 65. In the port input process, the detection signals S1 and S2 from the photo interrupters PH1 and PH2 are also input through the I / O port circuit 65. The detection signals S1 and S2 are signals indicating that medals have been detected on the upstream side and the downstream side of the passage.

  Next, in order to keep track of the current positions of the three rotary reels 4a to 4c, a rotating rotation control process is executed (ST23). The main control unit 50 can grasp the current position of each of the rotating reels 4a to 4c based on the input timing of the input signal from the index sensor and the number of drive pulses supplied to the stepping motor thereafter. Note that in the rotating rotation control process (ST23), the starting and stopping processes of the rotating reels 4a to 4c are also performed. For example, a drive signal for accelerating the rotating reel in stages from the stopped state to the constant speed rotation is also provided. Is generated.

  When the rotation rotation control process (ST23) is completed, the periodic update process is executed (ST24). In the scheduled update process, various software timer values for managing the game operation are updated by the decrement process (−1).

  Subsequently, one byte of the control command is output to the effect control unit 51 (ST25). Since one control command is 2 bytes long, one control command is transmitted by two successive timer interrupts. The control command indicates the game state of the main control unit 50, and the game state including the operation of the start lever 17 and the stop buttons 18a to 18c is notified to the effect control unit 51 by the control command. . Upon receiving such a control command, the production control unit 51 performs a control operation to turn on the LED lamp or generate a sound effect.

  Next, a medal information output process is executed, and for example, a medal insertion signal and a medal payout signal, each of which is a 1-bit signal, are output to the external concentration terminal board 56 (ST26). From this medal insertion signal and payout signal, the hall computer HC can grasp the number of medals inserted into each slot machine SL and the number of medals paid out from each slot machine SL. Further, the main control unit 50 outputs drive data for driving each LED lamp group to the game relay board 53 and the rotary relay board 57 (ST27).

  Thereafter, after determining the presence / absence of an abnormality such as a medal payout sensor or a door opening sensor (ST28), the saved register is restored and the interrupt process is completed (ST29).

  Although the embodiments of the present invention have been specifically described above, the specific description is not particularly intended to limit the present invention and can be appropriately changed.
