Description

  The present invention relates to a gaming machine, and more particularly to a transition to a special gaming state in a gaming machine using a gaming ball as a gaming medium.

  2. Description of the Related Art Conventionally, in order to improve the operating rate of gaming machines, development of gaming machines for improving the interest of gaming has been performed.

  In particular, since the symbol for displaying the game result directly informs the player that the game is profitable / disadvantageous, for example, a technique has been described in which the variation display mode of the symbol changes depending on the gaming state. As in Patent Document 1, making a new proposal on how to produce and display the symbol has led to an improvement in the fun of the game.

Under such circumstances, new game characteristics are provided by changing the symbol selection rate according to the gaming state (the normal gaming state that is difficult to shift to the specific gaming state advantageous to the player and the special gaming state that is easily shifted). It is desirable to provide a game machine.
JP 2003-199938 A

  However, if the selection rate of the symbol is changed according to the gaming state, in a gaming machine that determines the transition to the probability variation (= probability variation) state (special gaming state) according to the type of symbol, the transition to the probability variation state The rate will also change.

  Then, due to a large shift in the number of big hits due to a bias in the rate of transition to a probabilistic state, there is a problem that the amusement store side becomes difficult to make a forecast of the income and expenditure and the management of the amusement store becomes unstable End up.

  Therefore, as described in Patent Document 1, without changing the symbol selection rate in the gaming state, the corresponding symbol type is changed depending on the gaming state, etc., and the variation of the symbol type is increased, thereby increasing the interest of the game. It was only possible to improve.

  In this case, even if the game state is different, the symbol selection rate does not change, so it cannot be said that a new game is provided to the player.

  Accordingly, an object of the present invention is to provide a gaming machine capable of changing the symbol selection rate while keeping the transition rate to the special gaming state constant regardless of the gaming state.

In order to solve the above-mentioned problem, the gaming machine of the present invention according to claim 1 is changed to display means for performing variable display of symbols, an open state in which game balls are easy to win, and a closed state in which game balls are difficult to win. A variable winning device, a round number determining means for determining the number of rounds that is the number of times the variable winning device is switched between the open state and the closed state, and the variable winning device for one round from the open state. A closing condition storage means for storing a plurality of closing conditions for switching to a closed state, and distinguishing the symbol into a special symbol and a non-special symbol, and the special symbol further comprising a special symbol having a larger number of rounds and a special symbol having a smaller number of rounds . 1 of the special symbols, and symbol storage means for distinguishing the second special symbol consisting of many special symbols and less special symbol in the number of rounds to store a plurality of types of symbols, the symbol A symbol selection table storage unit that stores a plurality of symbol selection tables that determine a selection rate for selecting the symbol stored in the storage unit, and a symbol selection table storage unit that stores a predetermined condition based on the establishment of a predetermined condition. A symbol selection table determining means for determining any one symbol selection table from a plurality of symbol selection tables; a symbol determining means for determining a symbol based on a selection rate in the symbol selection table determined by the symbol selection table determining means; , On the condition that the special symbol is determined by the symbol determination means, specific game state control means for controlling a specific gaming state advantageous to the player , based on the symbol determined by the symbol determination means, a closure condition determining means for determining one of the closed condition from the closed condition stored in closed condition storage unit, FIG. When the first special symbol is determined by the determining means, it is determined to shift to the normal gaming state that is difficult to shift to the specific gaming state after the end of the specific gaming state, and the second symbol determining means determines the second special symbol. When a special symbol is determined, the game includes a special game state determination unit that determines to shift to a special game state that is easier to shift to the specific game state than the normal game state after the end of the specific game state, symbol selection table storage means, wherein in the first special symbol and the second selectivity of mutually identical and special symbols, and a first large number of rounds special special symbol and a large number of second round pattern of selectivity stores a plurality of symbol selection table that mutually different, characterized in that.

  In this way, the symbol selection table storage means has a plurality of selection rates of the first special symbol and the second special symbol that are all the same, and at least some of the selection rates of the symbols are different from each other. Since the symbol selection table is stored, it is possible to change the symbol selection rate according to the gaming state while maintaining the transition rate to the special gaming state constant regardless of the gaming state.

  In addition, since the probability of transition to the special gaming state is maintained constant regardless of the gaming state, the game store can set a standard for the number of jackpots (for example, the number of jackpots is 10 to 20 times during all day operation). As a result, the amusement shop side can easily estimate the income and expenditure, and the management of the amusement shop can be stabilized.

  Furthermore, it may be considered that the determination process for determining the probability variation with a certain probability and the determination process for determining the symbol with a changeable probability are processed independently, but the processing load increases. Of course, the relationship between the symbol and the probability change is lost (for example, the odd number symbol 777 among the jackpot symbols of 000 to 999 does not change), and the fun of the game is reduced. In the present invention, the interest rate of the game can be maintained because the symbol selection rate can be changed while retaining the relationship between the symbol and the probability change.

  According to a second aspect of the present invention, in addition to the configuration of the first aspect of the invention, the symbol selection table determining means can determine whether the gaming state is a normal gaming state or a special gaming state by the special gaming state determining means. The symbol selection table is determined from a plurality of symbol selection tables stored in the symbol selection table storage means, with the predetermined condition being determined as the above.

  As a result, the symbol selection rate changes depending on the gaming state, and the game content changes depending on the selected symbol, so that new gaming characteristics can be provided according to the gaming state, thereby further enhancing the interest of the game. It becomes possible.

  As a result, the symbol selection rate changes, and the round closing condition is determined based on the selected symbol, so that it is possible to provide a new gameability in which the round closing conditions are different.

  Even if the closing condition of the round at the jackpot can be changed, the rate of change in probability due to the occurrence of the jackpot is constant, so that the predictability of the balance at the game store side is not hindered.

  According to the present invention, the following effects can be obtained.

  That is, according to the present invention, the symbol selection table storage means is such that the selection rates of the first special symbol and the second special symbol are all the same, and at least some of the selection rates of the symbols are mutually mutually. Since a plurality of different symbol selection tables are stored, it is possible to change the symbol selection rate depending on the gaming state while maintaining the transition rate to the special gaming state constant regardless of the gaming state.

  Thereby, it becomes possible to provide a new gameability, and it is possible to further improve the interest of the game.

  Hereinafter, the best mode for carrying out the present invention will be described more specifically with reference to the drawings. Here, in the accompanying drawings, the same reference numerals are given to the same members, and duplicate descriptions are omitted.

  The game board 2 (FIG. 2) is surrounded by rails 6 and has a game area 2a in which game balls can flow down. The game area 2a includes a number of obstacles (not shown) such as game nails and windmills, a general winning port 12, a passing gate 13, a big winning port 15, an out port 16, and a starting port (starting region) 14. A game member such as an ordinary electric accessory (starting area) 18 is arranged.

  A liquid crystal display device (display means) 21 having a display area 21a capable of displaying an effect image (for example, animation corresponding to a game state or other notification information) is disposed on the back of the game board 2. Yes.

  The display area 21a of the liquid crystal display device 21 serving as a display means includes an area for displaying an effect image and a decorative symbol display area for performing variable display of decorative symbols.

  Three decorative symbols are displayed in the decorative symbol display region located in the center of the display region 21a. These decorative symbols are variably displayed separately.

  In the present embodiment, the rectangular display area 21a has a slightly smaller surface area than the game area 2a, but the surface area of the display area 21a is not particularly limited, and may be larger than the game area 2a. It can be small. Further, the shape of the display area 21a is not limited to a square, and may be another shape. For example, it may be circular.

  In the present embodiment in which the game board 2 is transparent, the display area 21 a of the liquid crystal display device 21 is disposed so as to be visible through the game board 2. Here, instead of the liquid crystal display device 21, for example, a CRT (cathode ray tube) or a plasma display can be used.

  Here, the general winning opening 12 is a device for paying out a predetermined number of game balls when a game ball is won, and the passing gate 13 is provided with normal symbol indicators 25a and 25b (described later) triggered by the passing of the game ball. It is a device for blinking.

  The large winning opening 15 which is a variable winning device has a closed state where the door is closed and it is difficult to accept the game ball (that is, a second state where it is difficult to accept the game ball), and the door is opened and the game ball is received. It is possible to change to an easy open state (that is, a first state in which a game ball can be easily received).

  Furthermore, inside the special winning opening 15, a passing area where a game ball can pass is provided. In the present embodiment, an operation in which the big prize opening 15 changes from the second state to the first state in a jackpot gaming state described later is referred to as a round operation.

  In addition, a special symbol display (variable display means) 24, normal symbol indicators 25a and 25b, four normal symbol start memory displays 23, and four special symbol start memory indicators are provided at the upper center of the game board 2. 22 are arranged respectively. The special symbol indicator 24 is composed of 7 segment LEDs, while the normal symbol indicators 25a and 25b, the normal symbol start memory indicator 23, and the special symbol start memory indicator 22 are each composed of LEDs. Yes.

  Next, on the upper right side of the game board 2 (FIG. 2), a round number display 26 is disposed so as to be visible through the game board 2.

  The round number indicator 26 is composed of two 7-segment LEDs, and can display numbers up to two digits by the two 7-segment LEDs. For example, numbers such as “0” “1” “2”... “13” “14” “15” can be displayed. The round number display 26 configured as described above displays the number of round operations (the number of times the open / closed prize opening 15 is opened / closed) during the big hit gaming state. For example, when the round operation is performed 15 times, “15” is displayed.

  The ordinary electric accessory 18 having a starting area has a game ball receiving opening, and the game ball that has entered the receiving opening passes through the inside of the ordinary electric accessory 18 (hereinafter, referred to as “reception ball”). The acceptance of a game ball to the ordinary electric accessory 18 is referred to as “winning the ordinary electric accessory 18”). Further, the ordinary electric accessory 18 has variable wings 18a and 18b, and can be changed between an open state in which game balls are easy to win and a closed state in which game balls are hard to win.

  Here, the closed state of the ordinary electric accessory 18 is a state in which the variable wings 18 a and 18 b are closed and the game ball is difficult to enter the ordinary electric accessory 18. On the other hand, the open state is a state in which the variable wings 18 a and 18 b are opened in an inverted octagonal shape so that the game ball can easily enter the ordinary electric accessory 18. Note that the ordinary electric accessory 18 is in a closed state during normal times.

  In addition, the start port 14 having a start area as in the case of the ordinary electric accessory 18 also has a game ball receiving port so that the game ball that has entered the receiving port passes through the inside of the start port 14. (Hereinafter, accepting a game ball to the start port 14 is referred to as “winning the start port 14”).

  In addition, when a game ball wins the above-mentioned start opening 14 or the ordinary electric accessory 18, the special symbol in the special symbol display 24 and the decorative symbol in the decorative symbol display area are changed and stopped based on the winning ball. .

  The out port 16 is a device in which game balls that have not won any of the general winning port 12, the starting port 14, the ordinary electric accessory 18, and the big winning port 15 flow in and are collected.

  A dish unit 5 is arranged below the game board 2 as described above, as shown in FIG. An upper tray 5a for storing the paid-out game balls and the game balls to be driven into the game area 2a is disposed at the upper portion of the tray unit 5 and overflows from the upper tray 5a by the payout at the lower portion of the tray unit 5. A lower tray 5b in which the played game balls are stored is disposed. Further, a shutter lever 8 is provided at a predetermined position of the upper plate 5a, which is operated when the game ball stored in the upper plate 5a is moved to the lower plate 5b and taken out at the end of the game.

  On the right side of the dish unit 5, a handle 7 that is rotated when a game ball is launched to the game area 2 a via the rail 6 is provided. The handle 7 is provided with a stop button (not shown) for stopping the launch of the game ball.

  When the player rotates the handle 7 and performs a launch operation, the game ball in the upper plate 5a is sent to the launching device 90 (see FIG. 5) by the launching ball supply device (not shown), The launching device 90 launches the game area 2 a along the rail 6.

  The passing gate 13 detects a passing game ball. The game balls that have passed through the passing gate 13 can be stored on hold, and the normal symbol indicators 25a and 25b are blinked on the basis of the stored information. In addition, the four normal symbol start memory indicators 23 described above display the number of reserved gates in the passage gate 13. Specifically, the number of reserved stored game balls that have passed through the passing gate 13 is displayed by the number of lighting of the normal symbol start memory display 23.

  The normal symbol displays 25a and 25b blink alternately, and the blinking of the normal symbol displays 25a and 25b ends (the time until the blinking ends is 30 seconds in the normal gaming state). In the probability variation gaming state (probability variation state) and in the short-time gaming state, it is 6 seconds.) When “winning” is displayed (hereinafter referred to as “ordinary winning time”), the ordinary electric accessory 18 variable wings 18a and 18b are opened in a reverse octave shape for a predetermined time, and are switched to an open state in which a game ball can be easily received (the open time is 0.2 seconds in the normal game state, while the probability change game state) If in medium and short game state, 2.2 seconds of opening is performed twice.)

  In addition, the winning balls to the starting port 14 and the ordinary electric accessory 18 can be memorized, and based on this memorized memory, the special symbols on the special symbol display 24 and the decorative symbols in the decorative symbol display area are variably displayed. Is done. In addition, the four special symbol start memory displays 22 described above display the number of winning prizes stored in the start port 14 and the ordinary electric accessory 18. Specifically, the number of winning prizes stored in the start opening 14 and the ordinary electric accessory 18 is displayed by the number of lighting of the special symbol start memory display 22.

  In addition, the symbols displayed on the special symbol display 24 that is a 7-segment LED include, for example, alphabets such as “F”, “A”, “H”, “L”, etc. Examples of the non-special symbol are “-” and the like. These symbols are displayed in a variable manner after the game ball is won at the start opening 18. The variation display of these symbols is finished, and the variation display result (here, the variation display result is a symbol that is stopped and displayed) is “F”, “A”, “H”, “ The case of an alphabet such as “L” is called a jackpot display mode. This jackpot display mode is a display mode for allowing the player to recognize that the gaming state shifts to a jackpot gaming state that is advantageous to the player as compared to the low probability state (that is, the game has become a “hit”). is there.

  Here, the jackpot display mode symbol is “F” which is the display mode of the probability variation rush symbol (probability variation rush symbol), “A” which is the display mode of the sudden probability variation rush symbol (sudden probability variation rush symbol), and the variation time It is subdivided into “H” and “L”, which are display modes of shortened symbols (short-time entry symbols).

  Then, when the variable symbol display result of the special symbol becomes a probability variation entry symbol or a sudden probability variation entry symbol (that is, when the probability variation big hit is reached), after the big hit gaming state is ended, the state is shifted to the probability variation gaming state. On the other hand, when the display mode of the special symbol is a short-time entry symbol (that is, a short-time big hit), after the big hit gaming state ends, the state is shifted to the short-time gaming state.

  In addition, the probability variation gaming state is a high probability state in which a transition to the big hit gaming state is easy to be performed. And the sudden probability change state means that the control time of the big hit gaming state is extremely shortened (for example, the opening time of the big prize opening 15 is 1 second and the number of rounds is only two rounds), and the big hit gaming state is in secret cover. Is a high-probability state in which the player moves without his knowledge.

  Further, the short-time gaming state refers to a state in which the average variation display time of special symbols and decorative symbols is shorter than normal, and the number of times of variation display per hour is improved, and is one aspect of the normal gaming state.

  Examples of the decorative symbols displayed in the decorative symbol display area include Arabic numerals such as “0”, “1”, “2”... “9”, and other symbols. These numbers and symbols are variably displayed together with the variably displayed special symbols after winning the game ball to the start port 14 or the ordinary electric accessory 18. Note that the variable display of these numbers and symbols ends, and the variable display result (that is, a combination of numbers and symbols that are stopped and displayed, also referred to as stop decorative symbols) is “3” “3” “3”. , “2”, “2”, “2” ”, etc., where the same numbers and symbols are aligned in a horizontal row are referred to as jackpot decorative symbols. This jackpot decoration pattern is a display mode for allowing the player to recognize that the game state shifts to a jackpot game state that is advantageous to the player compared to the normal game state (that is, it has become a “hit”). is there. Note that the variable display result other than the jackpot decorative symbol is referred to as a decorative symbol.

  In addition, the above-mentioned jackpot decoration symbol for causing the player to recognize that it has shifted to the jackpot gaming state is a probability variation jackpot decoration symbol which is a display mode showing probability variation jackpot, and a time bonus jackpot symbol which is a display mode which shows a short-time jackpot It is divided into and.

  And the probability variation big hit decoration symbol is a case where three predetermined numbers and symbols such as “7” and “3” are arranged in a horizontal row, while the short and short term big hit decoration symbol is a number other than the probability variation big hit decoration symbol. Or when three symbols are arranged in a horizontal row.

  The decorative symbol variable display is performed in conjunction with the special symbol variable display described above. Therefore, when the display mode (that is, the jackpot display mode) for allowing the player to recognize that the variable symbol display result of the special symbol has shifted to the jackpot gaming state is reached, the variable symbol display result of the decorative symbol is also the jackpot gaming state. It becomes a display mode (that is, a big hit decoration symbol) for allowing the player to recognize that it has shifted to.

  Further, when the jackpot display mode is a probability change display mode, the decorative display variable display result is to be a probability variation jackpot decoration pattern, while when the jackpot display mode is a non-probability display mode, The variable display result of the decorative symbol is a decorative symbol for time and big hit.

  For example, when the special symbol variable display result is “3” (that is, when the probability variation display mode is selected), the decorative symbol variable display result is in a state where three “3” s are arranged in a horizontal row. (That is, the variable display result of the decorative symbol becomes the probable big hit decorative symbol).

  As described above, in the present embodiment, when the probability variation jackpot is reached, the probability variation display mode is displayed on the special symbol display 24, while the probability variation jackpot decoration symbol is displayed on the decorative symbol display area. In addition, when the time and bonus is hit, the special symbol display 24 displays an uncertain change display mode, while the decorative symbol display area displays the time and bonus winning symbol.

  In the present embodiment, the above-mentioned winning memorized number and reserved memory number are displayed on the special symbol start memory display 22 and the normal symbol start memory display 23, respectively, but are not limited thereto. It may be displayed by other display methods. For example, it may be displayed in the display area 21a.

  Next, a control system of the pachinko gaming machine 1 shown in FIG. 1 will be described with reference to FIG. FIG. 5 is a block diagram showing a control system of the gaming machine shown in FIG.

  The control system of the pachinko gaming machine 1 includes a main control circuit 200, a sub control circuit 300 connected to the main control circuit 200, a payout control circuit 70a, and a launch control circuit 70b. This control system is mounted on the back side of the game board 2.

  A card unit 81 is connected to the payout control circuit 70a of the pachinko gaming machine 1.

  The card unit 81 is installed in the vicinity of the pachinko gaming machine 1 and has an insertion slot into which a prepaid card can be inserted, and reads the recorded information recorded on the prepaid card inserted into the insertion slot. Means, a lending command signal output means for outputting a lending command signal for instructing lending of game balls to the payout control circuit 70a in accordance with the operation of the ball lending operation panel 9 (FIG. 3), and a record read by the reading means Writing means for subtracting the number of loans commanded by the lending command signal output means from the lending possible number specified from the information, and recording the information on the prepaid card inserted in the insertion port; Yes.

  The main control circuit 200 has a main CPU (microcomputing processing device) 201 that controls the progress of the game of the pachinko gaming machine 1 according to a preset program, and returns various settings to initial values when an abnormality occurs or when the power is turned on. An initial reset circuit 204 that generates a reset signal, a lamp control circuit 207 that controls display of LEDs and the like, and a main RAM 203 that stores various data necessary for the operation of the main CPU 201 are mounted.

  Further, the main control circuit 200 includes a program for the main CPU 201 to process and control the gaming operation of the gaming machine 1, a jackpot determination table that is referred to when determining a jackpot by random lottery, and a symbol selection by random lottery. Special symbol determination table (refer to FIG. 12) referred to in FIG. 12, a normal hit determination table referred to when determining a normal hit by random lottery, and a variation pattern table referred to when selecting an effect display at the big hit (FIG. 12) 12), and a main ROM 202 that stores various probability tables that are referred to when lotteries are drawn.

  Here, as shown in FIG. 12, the special symbol determination table distinguishes the symbol displayed on the special symbol indicator 24 into a special symbol and a non-special symbol, and the special symbol is further described later. A plurality of types of symbols “H”, “F”, “A”, “L”, and “−” are stored so as to be distinguished from the second special symbol. Further, symbol selection tables T1 and T2 in which selection rates for selecting these symbols are defined are stored. Furthermore, a plurality of closing conditions (opening time, number of open balls) for one round are stored. Thus, the special symbol determination table has the functions of symbol storage means, symbol selection table storage means, and closing condition storage means.

  The main RAM 203 is a winning memory counter for storing the number of winning memories counted by the main CPU 201 (the number of winning balls to the starting port 14 and the ordinary electric accessory 18, that is, the number of game balls passing through the starting area), A holding memory counter for storing the number of holding memories counted by the main CPU 201 (the number of passing balls of the passing gate), for storing the number of game balls that have entered the big winning opening 15 during one round operation. Winning prize opening counter for storing the number of times the door of the big winning opening 15 opens and closes during one big hit gaming state (that is, the number of round operations in one big hit gaming state). A counter is provided.

  Here, in the present embodiment, the counter is set to 0 in the initial state and is reset by shutting off the power supply of the gaming machine 1 or the like. However, it may not be reset by turning off the power of the gaming machine 1.

  Furthermore, the value of the counter may be displayed in the display area 21a at a predetermined timing, or may be displayed by a player's operation.

  Further, the main RAM 203 has a high probability flag. Here, when the gaming state is shifted to the probability variation gaming state, a value (77) indicating the probability variation gaming state is set in the high probability flag, while the gaming state is a non-probability variation gaming state (a gaming state other than the probability variation gaming state). ), The value (00) indicating the non-probability variable gaming state is set.

  The main CPU 201 is a jackpot determining means, a symbol selection table determining means, a special symbol determining means (symbol determining means), a specific gaming state control means, a special gaming state determining means, a round number determining means, a closing condition determining means, and a variable winning device control. Each function of means, prize ball control means, variation pattern selection means, command transmission means, and game state transition means.

  Whether or not the big hit judging means makes a transition to a big hit gaming state advantageous to the player on condition that the game ball has passed through the starting area (starting port 14 or ordinary electric accessory 18) provided in the gaming area 2a. This is a means for performing the determination. Specifically, it is determined whether or not to shift the gaming state to the big hit gaming state based on the winning of the game ball in the starting port 14 or the ordinary electric accessory 18.

  For example, when a game ball wins the start opening 14 or the ordinary electric accessory 18, the jackpot determination means executes a jackpot determination process based on the jackpot determination random number value extracted by random lottery, If it becomes, it is determined to shift the gaming state to the big hit gaming state.

  Here, when it is determined by the big hit determination means that the game state is to be changed to the big hit game state, after the special symbol variable display on the special symbol indicator 24 and the decorative symbol in the display area 21a is finished, that is, the special symbol indicator 24. After the big hit display mode (big hit symbol) is displayed and the big hit decorative symbol is displayed in the decorative symbol display area, the game state transition means shifts the gaming state to the big hit gaming state.

  The symbol selection table deciding means is triggered by the fact that the big hit determining means determines that it is a big hit, according to the game state at the time of the big hit, each special symbol when determining the special symbol by the special symbol determining means described later The symbol selection table that determines the selection rate is determined.

  In FIG. 12, for example, when the game state at the time of jackpot determination is the normal game state, the symbol selection table T1 is determined. In the symbol selection table T1, the selection rate of the probability variation entry symbol (F symbol) is 50%, the selection rate of the sudden probability variation symbol (A symbol) is 10%, and the selection rate of the short time penetration symbol (H symbol) is 40%. And the selection rate of the time-short entry symbol (L symbol) is 0%. On the other hand, when the game state at the time of big hit is a probability variation game state that is a special game state, the symbol selection table T2 is determined. In this symbol selection table T2, the selection rate of the probability variation entry symbol (F symbol) is 60%, the selection rate of the short-time entry symbol (L symbol) is 10%, the selection rate of the short-time entry symbol (H symbol) is 30%, and The selection rate of the sudden change probability design (A design) is 0%.

  Here, it is difficult to make a transition to the big hit gaming state after the big hit gaming state, but the L and H symbols that become short gaming state (low probability state) when the average fluctuation display time is shorter than normal time are the first special symbols. It is called a symbol, and the F symbol and the A symbol that are in a high probability state where the transition to the big hit gaming state is likely to be performed after the end of the big hit gaming state are called second special symbols.

  The selection rate of the first special symbol combining the H symbol and the L symbol is determined when the big hit is determined even when the gaming state at the time of the big hit determination is the normal gaming state and is determined in the symbol selection table T1. Even if the gaming state is a probability variation gaming state and is determined in the symbol selection table T2, both are 60%. On the other hand, the selection rate of the second special symbol that combines the F symbol and the A symbol is determined when the big hit is determined even if the gaming state at the time of the big hit determination is the normal gaming state and is determined in the symbol selection table T1. Even if the gaming state is a probability variation gaming state and is determined in the symbol selection table T2, both are 40%.

  That is, the selection ratio of the H symbol and the L symbol, which are the first special symbols, and the selection ratio of the F symbol and the A symbol, which are the second special symbols, differ in the gaming state at the time of jackpot determination. Even so, it does not fluctuate. In other words, the selection rates of the first special symbol and the second special symbol are the same even if the gaming state at the time of jackpot determination is different.

  On the other hand, as described above, the selection rates of the special symbols (H, F, A, L) are all different from each other depending on the gaming state at the time of jackpot determination. For example, the selection rate of the H symbol is 40% when the gaming state at the time of jackpot determination is the normal gaming state and is determined in the symbol selection table T1, but the gaming state at the time of jackpot determination is the probability variation gaming state. When it is determined in the selection table T2, it is 30%. Further, the selection rate of the symbol A is 10% when the gaming state at the time of jackpot determination is the normal gaming state and determined in the symbol selection table T1, but the gaming state at the time of jackpot determination is a probabilistic gaming state. When it is determined in the selection table T2, it is 0%.

  That is, the selection rate of each special symbol varies depending on the symbol selection tables T1 and T2 to be determined.

  Accordingly, the rate of transition to the special gaming state is maintained constant regardless of the gaming state, and the symbol selection rate is changed depending on the gaming state.

  In this embodiment, there are two types of symbol selection tables (symbol selection tables T1 and T2), but the selection rates of the first special symbol and the second special symbol in all symbol selection tables are the same. As long as the selection rates of at least some of the symbols are different from each other, this may be a plurality of three or more symbol selection tables.

  The special symbol determining means is a means for determining a special symbol based on the selection rate of the special symbol set in the symbol selection table determined by the symbol selection table determining means after the big hit determination.

  Specifically, it is means for selecting, from the main ROM 202, a special symbol for executing variable display of the special symbol on the special symbol display 24 based on the determination result by the big hit determination means.

  When the special symbol is selected by the special symbol determining means, the main CPU 201 controls the lamp control circuit 207 to display the special symbol on the special symbol display 24.

  The special symbol is determined with reference to the special symbol determination table shown in FIG. 12 based on the symbol selection table determined by the symbol selection table determination means.

  For example, when it is a normal gaming state at the time of jackpot determination, a special symbol determination table based on the symbol selection table T1 is referred to. Therefore, if the random number lottery result is “3”, the special symbol is H symbol. Also, if the game is in the normal gaming state at the time of the big hit determination and the result of the random number lottery is “9”, the special symbol is A symbol.

  On the other hand, when it is in the state of probability variation at the time of jackpot determination, a special symbol determination table based on the symbol selection table T2 is referred to. Therefore, if the result of the random number lottery is “3”, the special symbol is the F symbol. When the result of random number lottery is “9”, the special symbol is an L symbol.

  The special symbols determined by the special symbol determining means are four types of H symbols, F symbols, A symbols, and L symbols, but are not limited to these four types.

  Here, in the H symbol, the number of rounds in the big hit game is 15 rounds, the open time of the big winning opening 15 per round is 30 seconds, and the number of open balls is 10. Then, the gaming state after the end of the control of the big hit gaming state (specific gaming state) becomes the short-time gaming state.

  In addition, in the F symbol, the number of rounds during the big hit game is 15 rounds, the open time of the big winning opening 15 per round is 30 seconds, and the number of open balls is 10. Then, the gaming state after the end of the control of the big hit gaming state becomes a probability variation gaming state.

  In the A symbol, the number of rounds during the big hit game is two rounds, the opening time of the big winning opening 15 per round is one second, and the number of open balls is one. Then, the gaming state after the end of the control of the big hit gaming state becomes a probability variation gaming state.

  Furthermore, in the L symbol, the number of rounds during the big hit game is two rounds, the open time of the big winning opening 15 per round is 30 seconds, and the number of open balls is ten. Then, the gaming state after the end of the control of the big hit gaming state becomes the short-time gaming state.

  The variation pattern determining means is means for selecting one of a plurality of variation patterns in accordance with the determination process by the special symbol selecting means.

  More specifically, in accordance with the special symbol determined by the special symbol determining means and the random number lottery, the variation for executing the variation display of the special symbol on the special symbol display 24 based on the variation pattern table (see FIG. 12). A means for selecting a pattern.

  When the variation pattern of the special symbol is selected by the variation pattern determining means, the main CPU 201 controls the lamp control circuit 207 to display the variation pattern on the special symbol display 24.

  Further, when the variation display pattern of the decorative symbol is selected by the variation pattern determining means, the main CPU 201 displays a variation command corresponding to the selected variation display pattern in order to display the variation display pattern in the decorative symbol display area 21b. Is a means for generating and setting.

  For example, when the determined special symbol is an H symbol or an F symbol, one of the variation commands “h4”, “h5”, and “h6” in the variation pattern table is extracted by random lottery. When “h4” is extracted, a variation pattern command having a variation time of “T5” and an effect display content of “normal reach” is generated and set.

  When the determined special symbol is the A symbol or the L symbol, only “h7” is extracted as the variation command. Then, the variation time is “T8”, and the contents of the effect display are generated and set suddenly as a change pattern command that is an open effect.

  The specific gaming state control means is a means for controlling at least one of the big hit gaming states (specific gaming state) among the gaming states determined by the big hit determining means and determined by the special symbol determining means.

  The special game state determination means is means for determining that the game state corresponding to the special symbol determined by the special symbol determination means is to be shifted to after the end of the big hit gaming state by the specific game state control means.

  For example, when the first special symbol is determined by the special symbol determining means, it is difficult to shift to the big hit gaming state after the big hit gaming state, but the short variation gaming state when the average variation display time is shorter than the normal time It is moved to. On the other hand, when the second special symbol is determined by the special symbol determining means, after the big hit gaming state is finished, the game is shifted to the probability variation gaming state in which the transition to the big hit gaming state is easy to be performed.

  The round number determination means is a means for determining the number of rounds, which is the number of times the round operation is repeated during control of the big hit gaming state.

  Note that the round operation is the second state when the closing condition determined by the closing condition determining means described later is satisfied after the big prize opening 15 is in the first state during the control of the big hit gaming state. It is a series of operations.

  The number of rounds is determined with reference to the special symbol determination table shown in FIG. 12 based on the special symbol determined by the special symbol determining means.

  For example, if the determined special symbol is an H symbol, the number of rounds is 15 times, and if the determined special symbol is an L symbol, the number of rounds is two.

  Then, according to the determined number of rounds, the variable winning device control means described later performs round control.

  The closing condition determination means determines a condition for ending one round operation, that is, a condition (opening time, number of open balls) for changing the special winning opening 15 from the first state to the second state.

  The closing condition is determined by referring to the closing condition storage means corresponding to the special symbol determined by the special symbol determining means (see FIG. 12).

  For example, when the determined special symbol is an H symbol, a closing condition is determined in which the opening time is “30 seconds” and the number of open balls is “10”. Then, after 30 seconds have passed since the grand prize opening 15 has entered the first state, or when ten game balls have entered the big prize opening 15, the second prize state is entered. On the other hand, when the determined special symbol is the A symbol, a closing condition is determined in which the opening time is “1 second” and the number of open balls is “1”. Then, when one second has elapsed since the grand prize winning opening 15 entered the first state or when one game ball enters the big winning prize opening 15, the second prize opening 15 is brought into the second state.

  The closing condition is not limited to the elapsed time after the big winning opening 15 is in the first state and the number of balls entered into the big winning opening 15, but may be other closing conditions. For example, the number of game balls that have passed through the start port 14 after the grand prize winning port 15 is in the first state can be used, or a condition in which both a predetermined elapsed time and a predetermined number of game balls are reached. You can also.

  The variable winning device control means realizes the round control by controlling a large winning opening solenoid 72S described later.

  The prize ball control means determines a predetermined number of times according to the establishment of the prize conditions (winning game balls at various prize openings (general prize opening 12, large prize opening 15, start opening 14, ordinary electric accessory 18, etc.)). This is means for controlling a payout device (payout means) 82 for paying out a prize ball.

  The payout device 82 is controlled by transmitting a control command (command) to the payout control circuit 70a.

  Programs for realizing the functions of the respective means described above are stored in the main ROM 202, and the main CPU 201 loads these programs from the main ROM 202 and updates and stores the calculation results in the main RAM 203 for execution. The functions of the respective means described above are realized. Of course, each of the above-described means may be configured by dedicated hardware.

  Further, the main CPU 201 serving as a command transmission means transmits various generated commands to the sub-control circuit 300, thereby executing the effects in the game.

Start port switches 19a and 19b, which are provided on the object 18 and detect the game balls won in the start port 14 or the ordinary electric accessory 18 are connected.

  In addition, the I / O port is provided in a passing area in the big winning opening 15 and detects a game ball that has won a prize in the general winning opening 12 as a count switch 19Se that is a sensor for detecting a gaming ball passing through the passing area. A general winning opening switch 19Sb, which is a sensor to be used, and a backup clear switch 74S for erasing various data stored in the main RAM 203 are connected.

  Furthermore, the I / O port is connected to actuators such as a movable member solenoid 71S for driving the variable blades 18a and 18b of the ordinary electric accessory 18 and a big prize opening solenoid 72S for opening and closing the door of the big prize opening 15. .

  Here, when each of the sensors detects a game ball, the detection signal is input to the main CPU 201 of the main control circuit 200. The main CPU 201 performs various operations such as driving and controlling the actuators 71S and 72S according to the input detection signal.

  Control commands (commands) are transmitted from the command output port 206 of the main control circuit 200 to the sub control circuit 300, the payout control circuit 70a, and the launch control circuit 70b, respectively.

  The sub-control circuit 300 that has received this control command (command) controls the operation of the liquid crystal display device 21, the speakers 8a and 8b, and the lamp / LED 39a, and the payout control circuit 70a that has received this control command (command) and the launch. The control circuit 70b controls the operations of the dispensing device 82 and the launching device 90.

  The payout control circuit 70a is connected to a payout device 82 for paying out award balls and rental balls. The payout control circuit 70a drives and controls the payout device 82 in accordance with a payout command signal output from the main control circuit 200 on condition that a game ball has entered the general winning opening 12 and the big winning opening 15 and the like. A number of game balls are paid out as prize balls. Also, the payout control circuit 70a controls the payout device 82 in accordance with the payout command signal output from the card unit 81, and pays out a predetermined number of game balls as the payable balls.

  A launch device 90 that launches a game ball toward the game area 2a is connected to the launch control circuit 70b. Further, the launch control circuit 70 b causes the launching device 90 to launch a game ball by drivingly controlling the launch solenoid in accordance with the rotation operation of the handle 7.

  Further, the lamp control circuit 207 is electrically connected with LEDs such as the round number display 26, the special symbol display 24, the normal symbol displays 25a and 25b, the normal symbol start memory display 23, and the special symbol start memory display 22. It is connected to the. The lamp control circuit 207 performs display control of the LED based on the control of the main CPU 201.

  Next, the configuration of the sub control circuit 300 will be described. The sub control circuit 300 includes a sub CPU 301, a program ROM 302, a work RAM 303, a command input port (not shown), an image control circuit 305, an audio control circuit 306, and a lamp control circuit 307.

  The sub CPU 301 determines a command received from the main control circuit 200 via the command input port, and controls the image control circuit 305, the sound control circuit 306, the lamp control circuit 307, and the like according to the determination result.

  In addition, the sub CPU 301 performs instruction control on the image control circuit 305, thereby performing variable display control of decorative symbols in accordance with the variation pattern command, display control of other effect images, and the like.

  Further, the sub CPU 301 includes a decoration design determining unit.

  The decorative symbol determining means refers to the symbol command transmitted from the main CPU 201 and the decorative symbol determining table (see FIGS. 14, 15, and 16) based on the random number lottery, and stops after change displayed on the liquid crystal display device 21. It is a means for determining a decorative design.

  For example, when the symbol command “z1” is transmitted, the decorative symbol determination table (big hit) shown in FIG. 14 is referred to. If the random lottery result is a value of “0 to 1”, the decorative symbol is determined to be “222”.

  The program ROM 302 has a control program (effect data) for the sub CPU 301 to process control the image control circuit 305 based on various commands output from the main control circuit 200 and a control for process control of the audio control circuit 306. Program, control program for controlling the processing of the lamp control circuit 307, data relating to a plurality of types of notifications, and a decorative symbol determination table (FIGS. 14, 15, and 16) referred to when selecting a decorative symbol at the time of a big hit by random number lottery Etc.) are stored.

  The work RAM 303 serves as a temporary storage unit when the sub CPU 301 performs processing control according to the control program, and includes a reception buffer area (not shown) for storing commands transmitted from the main CPU 201, and processing. A work area (not shown) for storing data necessary for control is allocated.

  In addition, the work RAM 303 includes a big hitting ball counting counting flag (sub). Here, in the big hitting ball counting flag (sub), the same value as the big hitting ball counting flag provided in the main RAM 203 is set.

  The image control circuit 305 executes display such as variable display of decorative symbols in the display area 21a in response to an instruction from the sub CPU 301 (instruction based on effect data set in a predetermined work area of the work RAM 303). The image data ROM 305b for storing various image data and the corresponding image data are extracted from the image data ROM 305b in accordance with the control from the sub CPU 301. Based on the extracted image data, the decorative symbols can be variably displayed and produced. A VDP (Video Display Processor) 305a that generates data for executing image display and the like, and a D / A conversion circuit (D / A converter) 305d that converts display image data generated by the VDP 305a into an analog signal. It has.

  For example, the image control circuit 305 performs image display control processing for causing the display area 21a to perform variable display of decorative symbols, display of effect images, and the like on the display area 21a based on an instruction from the sub CPU 301.

  Further, for example, the image data ROM 305b includes decoration symbol image data for variably displaying the decoration symbol determined by the decoration symbol determination means in the decoration symbol display area, effect image data for displaying the effect image in the display area 21a, and the like. Remember. Here, each image data includes a plurality of pixel data (data in dot units) necessary to display each image data in the display area 21a.

  Here, a VRAM 305c having two buffer areas is connected to the VDP 305a. The VDP 305a performs the following processing when generating data for executing display in the display area 21a based on an instruction from the sub CPU 301 transmitted every predetermined time (for example, 1/30 second). The VDP 305a reads predetermined image data from the image data ROM 305b, develops it to the VRAM 305c, and reads the decompressed image data from the VRAM 305c. Specifically, the VDP 305a performs expansion processing on one buffer area provided in the VRAM 305c, and reads image data that has already been expanded from the other buffer area. Next, the VDP 305 a switches between a buffer area to be expanded and a buffer area to be read based on an instruction from the sub CPU 301. The VDP 305a displays the read image data on the display area 21a via the D / A conversion circuit 305d.

  In this embodiment, a VRAM is used as a storage device for developing image data. However, the present invention is not limited to this, and other storage devices may be used. For example, an SDRAM that can read and write data at high speed may be used.

  Speakers 8 a and 8 b are connected to the audio control circuit 306. The sound control circuit 306 generates a sound signal based on the control of the sub CPU 301. The speakers 8a and 8b generate sound based on the input sound signal.

  As described above, the speakers 8a and 8b, the lamp / LED 39a, and the liquid crystal display device 21 perform an effect based on the effect data set by the sub CPU 301 (control program).

  Each process in the pachinko gaming machine 1 is controlled by the main control circuit 200 and the sub control circuit 300. The main control circuit 200 processes all or part of the processes controlled by the sub control circuit 300. Alternatively, the sub control circuit 300 may process all or part of the processing controlled by the main control circuit 200.

  Next, a processing procedure by the main control circuit 200 of the pachinko gaming machine 1 according to the present embodiment will be described with reference to FIG.

  FIG. 4A is a flowchart showing a system timer interrupt processing procedure executed so as to interrupt the main process at a predetermined cycle (for example, 2 msec), and FIG. 4B shows the present embodiment. It is a flowchart which shows the main process sequence of the pachinko gaming machine 1 in FIG.

  First, the system timer interrupt process will be described with reference to FIG.

  In step S100, the main CPU 201 saves the information stored in the register.

  In step S110, the main CPU 201 updates values such as a jackpot determination random number value, a jackpot symbol determination random number value, a normal hit determination random number value, and the like.

  In step S120, the main CPU 201 performs switch input detection processing. Hereinafter, the switch input detection process will be specifically described.

  The main CPU 201 detects the detection signals output from the count switch 19Se, the general prize opening switch 19Sb, the start opening switch 19a, the passing gate switch 19Sa, and the like through the I / O port. Then, the main CPU 201 that detects these detection signals executes the following processes (1) to (3) according to the contents of the detected detection signals.

  (1) When the main CPU 201 detects a detection signal from the count switch 19Se, the main CPU 201 adds “1” to the value of the big prize winning prize counter.

  (2) When the main CPU 201 detects a detection signal from the start port switch 19a provided at the start port 18, the main CPU 201 confirms the value of the winning memory counter. When the value of the winning memory counter is, for example, 4 or less, “1” is added to the value of the winning memory counter, and the big hit determination random number value and the big hit symbol determination random number value are extracted by random lottery. The jackpot determination random number value and the jackpot symbol determining random number value are stored in the winning storage area of the main RAM 203 as winning storage.

  Further, the main CPU 201 is in a state where the special symbol display unit 24 cannot newly display the variation of the special symbol (for example, when the symbol in the special symbol display unit 24 is already in the variation display), The lamp control circuit 207 is controlled to display on the special symbol start memory display 22 that the winning memory is present until the variation display can be newly performed.

  When the value of the winning memory counter is 0, the special symbols and decorative symbols are not displayed in a variable manner, and the number of winning memories is 0. When the value of the winning memory counter is 1, it is in a state in which special symbols and decorative symbols are displayed in a variable manner, and the number of winning memories is 0. When the value of the counter is 5, the special symbol or decorative symbol is displayed in a variable state, and the special symbol start memory display 22 indicates that the number of winning memories is four. (In other words, the special symbol start memory display 22 displays a value obtained by subtracting “1” from the winning memory counter).

  (3) When the main CPU 201 detects a detection signal from the pass gate switch 19Sa provided in the pass gate 13, the main CPU 201 checks the value of the pending storage counter. If the value of the reserved storage counter is 4 or less, for example, “1” is added to the value of the reserved storage counter, and a random number for normal hit determination is extracted by random lottery, and the normal hit determination randomness is extracted. The numerical value is stored as a reserved storage in a later-described reserved storage area of the main RAM 203.

  In addition, the main CPU 201 cannot newly perform the blinking display of the normal symbols on the normal symbol displays 25a and 25b (for example, when the symbols on the normal symbol displays 25a and 25b are already blinking). If there is, the lamp control circuit 207 is controlled to display on the normal symbol start memory display 23 that the reserved memory exists until the symbols can be blinked on the normal symbol displays 25a and 25b. Do it.

  When the value of the reserved storage counter is 0, the normal symbol display units 25a and 25b do not perform the normal symbol fluctuation display, and the number of reserved memories is 0. When the value of the reserved memory counter is 1, the normal symbol display units 25a and 25b are in a state in which the normal symbol fluctuation display is being performed, and the number of reserved memories is 0. When the value of the counter is 5, the normal symbol variation display is being performed, and the normal symbol start memory display 23 indicates that the number of reserved memories is four. It is. (That is, the normal symbol start memory display 23 displays a value obtained by subtracting “1” from the reserved memory counter).

  In step S130, the main CPU 201 is in the open state in which the special symbols and decorative symbols that are variably displayed, the remaining change display time of the decorative balls, the remaining opening time of the starter 18 in the open state where the game balls are easily received, and the game balls are easily received. The remaining opening time of the door 15a of the big prize opening 15 is updated.

  In step S140, the main CPU 201 outputs game information such as execution of decorative symbol variation display and occurrence of jackpot to a hall computer installed in the game hall.

  In step S150, the main CPU 201 drives and controls solenoids such as the movable member solenoid 71S and the special prize opening solenoid 72S.

  In step S <b> 160, the main CPU 201 outputs a symbol command, a variation command, a jackpot command, a chance command, a standby state command, other commands, and the like to the sub-control circuit 300.

  In step S170, the main CPU 201 controls the lamp control circuit 207 to cause the special symbol start memory display 22 to display the number of winning memory stored in the winning memory area ("1" to "4") of the main RAM 203. To do. Further, the main CPU 201 controls the lamp control circuit 207 in order to cause the normal symbol start memory display 23 to display the reserved memory number of the passage gate 13 stored in the main RAM 203.

  Further, when the variation display pattern or variation display result of the special symbol is determined in the special symbol storage check process (FIG. 6) described later, the main CPU 201 displays the variation display pattern or variation display result on the special symbol display 24. The lamp control circuit 207 is controlled in order to display it. As a result, the special symbol on the special symbol display 24 is variably displayed based on the variation display pattern determined by the special symbol memory check process, and then stops at the variation display result determined by the process.

  Further, when the normal symbol blinking display pattern or stop mode is selected in step S30 described later, the main CPU 201 performs lamp control to display the blinking display pattern or stop mode on the normal symbol displays 25a and 25b. The circuit 207 is controlled. As a result, the normal symbols on the normal symbol displays 25a and 25b are blinked on the basis of the blinking display pattern selected in step S30, and then stopped in the stop mode selected in the same step.

  Further, the main CPU 201 outputs a control command for instructing to display an error such as a ball breakage or a full lower pan on a predetermined lamp, and other necessary control commands to the sub-control circuit 300.

  In step S180, the main CPU 201 issues a payout command for instructing to pay out a predetermined game ball as a prize ball in accordance with the type of a prize opening into which a game ball has entered (such as a general prize opening 12 or a big prize opening 15). A control command such as a signal is output to the payout control circuit 70a.

  In step S190, the main CPU 201 restores the information saved in step S100 to the register.

  Next, main processing by the main control circuit 200 will be described with reference to FIG.

  In step S <b> 10, the main CPU 201 restores or initializes various settings in the pachinko gaming machine 1 to the setting contents when the power was turned off last time.

  In step S20, the main CPU 201 executes a special symbol control process (see FIG. 5) which will be described later in detail.

  In step S30, the main CPU 201 executes normal symbol control processing (see FIG. 8), which will be described later in detail.

  In step S40, the main CPU 201 updates values such as a random number for determining a variation pattern.

  The main CPU 201 repeats the processes from step S20 to step S40 described above.

  Next, the special symbol control process in step S20 will be described with reference to FIG. FIG. 5 is a flowchart showing the processing procedure of the special symbol control processing according to the present embodiment.

  In step S20-1, the main CPU 201 executes a process of loading a control state flag. The control state flag is a flag indicating a game state in the special symbol game. The main CPU 201 determines whether or not to execute each process in step S20-2 to step S20-10 based on this control state flag.

  In step S20-2, the main CPU 201 performs a special symbol storage check process, which will be described later in detail.

  Here, the main CPU 201 performs jackpot determination based on the jackpot determination random value included in the winning memory. Further, determination of jackpot symbol (special symbol), off-line symbol (non-special symbol), and determination of the variation pattern of the decorative symbol displayed on the special symbol indicator 24 are performed.

  In step S20-3, the main CPU 201 determines that the control state flag is a value (01) indicating special symbol variable display time management and the value of the waiting time timer in which the variable display time is set is “0”. A value (02) indicating special symbol display time management is set in the control state flag, and a waiting time after determination (for example, 1 second) is set in the waiting time timer.

  In step S20-4, the main CPU 201 indicates that the control state flag is a value (02) indicating the special symbol display time management process, and the value of the waiting time timer in which the waiting time after determination is set is “0”. In addition, if the result of the big hit determination performed in the special symbol check process (details will be described later) in the special symbol check process in step S20-2 is to shift the gaming state to the big hit gaming state, A value (03) indicating the start interval management process is set in the control state flag, and (00) is set in the high probability flag. Then, the time corresponding to the big hit start interval (for example, 10 seconds) is set in the waiting time timer, and the special symbol display time management process is ended.

  Further, when the result of the jackpot determination performed in the jackpot determination process does not shift the gaming state to the jackpot gaming state (in the case of a loss), the main CPU 201 indicates a value indicating the special symbol game end process (08). Is set in the control state flag, and the special symbol display time management process is terminated.

  In step S20-5, the main CPU 201 sets the control state flag to a value (03) indicating the jackpot start interval management, and the value of the waiting time timer in which the time corresponding to the jackpot start interval is set is “0”. Whether or not the condition is satisfied, the step is terminated.

  When the above conditions are satisfied, the main CPU 201 adds “1” to the special winning opening opening number counter in this step and controls the special winning opening solenoid 72S so as to open the door of the special winning opening 15. . Thereby, the control of the round operation in which the first prize opening 15 is in the first state in which it is easy to accept the game ball is started, and the game ball can pass through the passage area.

  Next, the main CPU 201 sets a value (04) indicating that the big prize opening is being opened to the control state flag, and sets the upper opening limit time (for example, 30 seconds) to the big prize opening time timer.

  In step S20-6, the main CPU 201 confirms the closing condition determined in S20-2-10, which will be described later, when the control state flag is a value (04) indicating the special winning opening opening process. Next, the first condition that the value of the big prize opening time timer in which the opening time of the closing condition determined in S20-2-10 is set is “0”, or the game ball is placed in the big prize opening 15 In step S20-2-10, it is confirmed whether or not the second condition that the number of balls entered is equal to or greater than the number of open balls of the closing condition determined in S20-2-10.

  Here, the main CPU 201 controls the big prize opening solenoid 72S so as to close the door of the big prize opening 15 when either of the first condition and the second condition is satisfied, Further, a value (05) indicating the winning ball remaining ball monitoring process is set in the control state flag, and the remaining winning ball remaining ball monitoring time (for example, 1 second) is set in the waiting time timer.

  In step S20-7, the main CPU 201 sets the control state flag to a value (05) indicating monitoring of the winning ball remaining ball monitoring and the value of the waiting time timer in which the winning ball remaining ball monitoring time is set to “0”. It is confirmed whether or not.

  Then, when satisfying any of the above conditions, the main CPU 201 confirms the number of rounds determined in S20-2-9 described below. Then, it is confirmed whether or not a condition that the value of the winning prize opening number counter is equal to or greater than the number of rounds (for example, “15” or greater). The special winning opening opening number counter counts rounds in the big hit gaming state.

  Further, when the value of the big prize opening number counter is equal to or more than the number of rounds, the main CPU 201 sets a value (07) indicating the big hit end interval in the control state flag, and sets the big prize opening number counter to “ Set 0 ”. Then, the time corresponding to the jackpot end interval is set in the waiting time timer.

  On the other hand, when the value of the winning prize opening number counter is not equal to or greater than the number of rounds, the main CPU 201 sets a value (06) indicating management of waiting time for reopening the winning prize opening in the control state flag, and the interval between rounds. The time corresponding to is set in the waiting time timer.

  In step S20-8, the main CPU 201 confirms whether or not the value (06) indicating the large winning opening reopening waiting time is set in the control state flag, and the value indicating the large winning opening reopening waiting time (06). ) Is not set, the step ends. On the other hand, when the value (06) indicating the waiting time for reopening the big prize opening is set, whether or not the value of the waiting time timer in which the time corresponding to the interval between rounds is set next is “0”. To check. When the value of the waiting time timer is “0”, the main CPU 201 adds “1” to the value of the special winning opening opening number counter and opens the door of the special winning opening 15. The big prize opening solenoid 72S is controlled. As a result, the special winning opening 15 is opened and the control of the round operation is started. Next, the value (04) indicating that the special winning opening is being opened is set in the control state flag, and the opening time determined in S20-2-10 (for example, 30 seconds) is set in the special winning opening timer. To do.

  In step S20-9, the main CPU 201 determines that the control state flag is a value (07) indicating the jackpot end interval process, and the value of the waiting time timer in which the time corresponding to the jackpot end interval is set is “0”. Sets the value (08) indicating the special symbol game end process to the control state flag.

  Further, the main CPU 201 confirms whether or not an odd number such as “7” or “3” has become a stop symbol on the special symbol display 24, that is, whether or not the big hit symbol has become a probability change display mode. .

  Here, when the main CPU 201, which is the game control means, confirms that the big hit symbol is in the probability variation display mode, the main CPU 201 sets (77) to the high probability flag and shifts the gaming state to the probability variation gaming state. .

  In step S20-10, the main CPU 201 subtracts “1” from the winning storage counter when the control state flag is a value (08) indicating the end of the special symbol game. The main CPU 201 shifts the data stored in the special symbol storage areas (“1” to “4”) to the special symbol storage areas (“0” to “3”), respectively, and also stores the special symbol storage. A value (00) indicating a check is set in the control state flag.

  The special symbol storage area is a special symbol storage area that is assigned to the main RAM 203 and is extracted based on a condition that a game ball has won the start opening 14 or the ordinary electric accessory 18. It is a winning storage area that is stored in order from 0 ". The jackpot determination random number stored in the special symbol memory area (“1” to “4”) corresponds to the winning memory displayed on the special symbol start memory indicator 22, and the special symbol memory area “ The random value for jackpot determination stored in 0 ″ is used for the jackpot determination in step S20-2.

  Next, the special symbol memory check process in step S20-2 will be described with reference to FIG. FIG. 6 is a flowchart showing the procedure of the special symbol storage check process according to the present embodiment.

  In step S20-2-1, the main CPU 201 confirms whether or not the control state flag is a value (00) indicating a special symbol storage check, and as a result of the confirmation, the control state flag indicates a special symbol storage check. When the value is (00), the process proceeds to step S20-2-2. On the other hand, when the control state flag is not the value (00) indicating the special symbol storage check, the special symbol storage check process is terminated. .

  In step S20-2-2, the main CPU 201 confirms whether or not the value of the winning memory counter is “0” (that is, whether or not the number of winning memory is “0”). If the value of the winning memory counter is “0”, the process proceeds to step S20-2-3. If the value of the winning memory counter is not “0”, the process proceeds to step S20-2-4. .

  In step S20-2-3, the main CPU 201 generates and sets a standby state command for instructing to display a demonstration effect image. Note that the standby state command indicates that the gaming state is the standby state (the special symbol display unit 24 does not display the special symbol or the decorative symbol variable display operation on the liquid crystal display device 21 and is not in the big hit gaming state. This is generated in the case of

  In step S20-2-4, the main CPU 201 sets a value (01) indicating special symbol variation display time management in the control state flag.

  In step S20-2-5, the main CPU 201 makes a jackpot determination based on the jackpot determination random number included in the winning memory.

  The jackpot determination table refers to a jackpot determination table to be referred to when the high probability flag is a value (00) indicating a non-probability changing gaming state and when the high probability flag is a value (77) indicating a probability changing gaming state. It is different. In other words, the jackpot determination table referred to in the probability variable gaming state has a larger number of jackpot determination values than the jackpot determination table referred to in the non-probability variable gaming state, so that it is easier to determine that the jackpot determination table.

  In step S20-2-6, the main CPU 201 determines whether or not the result of the jackpot determination performed in step S20-2-5 is to shift the gaming state to the jackpot gaming state (that is, whether or not the jackpot has been won) Confirm). Then, when the result of the big hit determination is that which shifts the gaming state to the big hit gaming state (big hit), the main CPU 201 proceeds to the process of step S20-2-8. On the other hand, if the result of the jackpot determination is not what shifts the gaming state to the jackpot gaming state, the process proceeds to step S20-2-7.

  In step S20-2-7, the main CPU 201 determines that the variable symbol display result (stop symbol) of the special symbol is off, and generates and sets a symbol command “z0” based on the determination.

  In step S20-2-8, the main CPU 201 performs a jackpot symbol determination process to be described later in detail. Here, the main CPU 201 determines the variable display result (stop symbol) of the special symbol indicating the big hit based on the random number lottery with reference to the special symbol determination table of FIG.

  In step S20-2-9, the main CPU 201 performs round number determination processing to determine the number of rounds.

  Here, the number of rounds refers to the upper limit number of round operations performed during the big hit gaming state. For example, when the number of rounds is determined to be “15” by the round number determination process, the round operation is performed up to 15 times in the big hit gaming state.

  The main CPU 201, which is the round number determination means, determines the number of rounds with reference to the special symbol determination table shown in FIG. 12 based on the special symbol determined in S20-2-8. That is, the type of special symbol and the number of rounds correspond to each other, and the corresponding number of rounds is determined for each special symbol.

  For example, if the special symbol determined in S20-2-8 is an H symbol, the number of rounds is determined to be “15”.

  In step S20-2-10, the main CPU 201 performs a closing condition determination process.

  Here, the closing condition means that the prize winning port 15 which is a variable winning device changes from the first state (the state where the door is open) to the second state (the state where the door is closed). This refers to a condition for switching, and when either the opening time or the number of open balls reaches a predetermined condition, the door of the special winning opening 15 is closed. For example, when the closing condition determining process determines the closing condition where the opening time is “30 s” and the number of opened balls is “10”, 30 seconds have passed since the big winning opening 15 was opened, or a game ball When 10 balls enter the big prize opening 15, the big prize opening 15 is closed.

  Based on the special symbol determined in S20-2-8, the main CPU 201, which is a closing condition determining unit, refers to the special symbol determination table shown in FIG. In other words, the types of special symbols correspond to the closing conditions, and the corresponding closing conditions are determined for each special symbol.

  For example, the closing condition in the case where the special symbol determined in S20-2-8 is the F symbol is determined such that the opening time is “30 s” and the number of open balls is “10”.

  In step S20-2-11, the main CPU 201 performs a process of determining a variation pattern of the special symbol and the decorative symbol.

  The main CPU 201 determines a variation pattern (effect display content) of the decorative symbol with reference to the variation pattern table shown in FIG. 12 based on the extracted random number value and the determination result of the jackpot. Based on the determination, a variation command is generated and set.

  For example, the main CPU 201 is extracted when the result of the jackpot determination performed in step S20-2-5 is not a jackpot and the special symbol is determined as “-” in step S20-2-7. When the random value is “0 to 79”, “normal variation” is determined as the variation pattern of the decorative design, and the variation command “h0” is generated and set based on the determination. At this time, the variation time is “T1”.

  On the other hand, in the main CPU 201, the result of the jackpot determination performed in step S20-2-5 is a jackpot, and the special symbol determined in step S20-2-8 is “H” or “F”. In the case where the extracted random number value is “0 to 59”, “normal reach” is determined as the variation pattern of the decorative symbol, and the variation command “h4” is generated and set based on the determination. At this time, the variation time is “T5”.

  Further, the main CPU 201 determines that the result of the jackpot determination performed in step S20-2-5 is a jackpot and the special symbol determined in step S20-2-8 is “A” or “L”. Determines the “sudden opening effect” as the variation pattern of the decorative design, and generates and sets the variation command “h7” based on the determination. At this time, the variation time is “T8”.

  In step S20-2-12, the main CPU 201 sets a variable display time corresponding to the variation pattern determined by the process of step S20-2-11 in the waiting time timer.

  Note that the variable display of the decorative symbols is performed based on the variation pattern determined in step S20-2-11 during the variable display time set in step S20-2-12. When the variable display time ends, the decorative symbol that is variably displayed stops with the symbol based on the symbol command being displayed.

  Further, the special symbol variable display on the special symbol display 24 is performed for the variable display time set in step S20-2-11. When the variable display time ends, the special symbol that is variably displayed stops in a state where the stop symbol determined in step S20-2-7 or step S20-2-8 is displayed.

  In step S20-2-13, the main CPU 201 erases the random number value and the like used for the special symbol storage check process this time from a predetermined storage area.

  Next, the jackpot symbol determination process in step S20-2-8 will be described with reference to FIG. FIG. 7 is a flowchart showing the procedure of the jackpot symbol determination process according to the present embodiment.

  In step S20-2-8-1, the main CPU 201 confirms whether or not the gaming state is a probability variation gaming state, that is, whether or not the value (77) indicating the probability variation gaming state is set in the high probability flag. To do. Then, when the value (77) indicating the probability variation state is set in the high probability flag, the main CPU 201 proceeds to the process of step S20-2-8-3. On the other hand, when the value (77) indicating the probability variation state is not set in the high probability flag, that is, when the gaming state is the normal gaming state, the process proceeds to step S20-2-8-2.

  In step S20-2-8-2, the main CPU 201 selects the jackpot symbol determination random number value extracted by random number lottery with a value of “0-9” and the symbol selection table T1 shown in FIG. With reference to the special symbol determination table shown, the stop symbol of the special symbol indicating the big hit is determined, and a symbol command corresponding to the determined special symbol is generated.

  For example, when the random number value is “4-8”, the main CPU 201 determines the stop symbol to be the second special symbol “F”, and generates and sets the symbol command “z2”. .

  In step S20-2-8-3, the main CPU 201 executes the processing shown in FIG. 12 based on the jackpot symbol determination random number value extracted by the random number lottery of “0-9” and the symbol selection table T2 shown in FIG. With reference to the special symbol determination table shown, the stop symbol of the special symbol indicating the big hit is determined, and a symbol command corresponding to the determined special symbol is generated.

  For example, when the random number is “0 to 2”, the main CPU 201 determines the stop symbol as “H” as the first special symbol, and generates and sets the symbol command “z1”. .

  Note that the selection rates of the first special symbol and the second special symbol in the symbol selection table T1 are the same as the selection rates of the first special symbol and the second special symbol in the symbol selection table T2. On the other hand, the selection rate of each special symbol (H, F, A, L) in the symbol selection table T1 is different from the selection rate of each special symbol in the symbol selection table T1.

  Specifically, the selection rate of the first special symbol combining the H symbol and the L symbol is the case where the gaming state at the time of jackpot determination is the normal gaming state and is determined in the symbol selection table T1. Even if the gaming state at the time of the big hit determination is a probability variation gaming state and is determined in the symbol selection table T2, both are 60%. On the other hand, the selection rate of the second special symbol that combines the F symbol and the A symbol is determined when the big hit is determined even if the gaming state at the time of the big hit determination is the normal gaming state and is determined in the symbol selection table T1. Even if the gaming state is a probability variation gaming state and is determined in the symbol selection table T2, both are 40%.

  On the other hand, for example, the selection rate of the H symbol is 40% when the gaming state at the time of jackpot determination is a normal gaming state and is determined in the symbol selection table T1, but the gaming state at the time of jackpot determination is a probabilistic gaming state When it is determined in the symbol selection table T2, it is 30%. Further, the selection rate of the symbol A is 10% when the gaming state at the time of jackpot determination is the normal gaming state and determined in the symbol selection table T1, but the gaming state at the time of jackpot determination is a probabilistic gaming state. When it is determined in the selection table T2, it is 0%.

  Therefore, in the jackpot symbol determination process, the probability of probability variation jackpot does not vary depending on the gaming state at the time of jackpot determination, but the selection rate of each special symbol varies.

  Next, the normal symbol control process in step S30 will be described with reference to FIG. FIG. 8 is a flowchart showing the processing procedure of the normal symbol control processing according to the present embodiment.

  In step S30-1, the main CPU 201 executes processing for loading the normal symbol control state flag. The normal symbol control state flag is a flag indicating the state of the game in the normal symbol game, and the main CPU 201 executes each process from step S30-2 to step S30-6 based on the normal symbol control state flag. Determine whether to execute.

  In step S30-2, the main CPU 201 performs a normal symbol storage check process. Here, a normal winning lottery process is performed. Then, according to the result of the lottery process, determination of a normal symbol stop symbol, a normal symbol variation display pattern, a regular symbol variation display time, and the like is performed.

  In the normal lottery, the normal lottery table to be referred to is different depending on whether the game state is the normal game state or the game state is the open state increasing game state (probability game state or short-time game state). ing. In other words, the normal lottery table that is referred to in the open state increased gaming state has a larger number of normal per lottery values than the normal per lottery table that is referred to in the normal gaming state, so that it is easier to win a normal win. Yes.

  In step S30-3, the main CPU 201 indicates that the normal symbol control state flag is a value (01) indicating normal symbol variation time management, and the value of the normal symbol waiting time timer in which the variation display time of the ordinary symbol is set is “0”. ”, The normal symbol variation display is terminated, a value (02) indicating normal symbol display time management is set in the normal symbol control state flag, and a waiting time after determination (for example, 0.5 Second) is set to the normal symbol waiting time timer.

  In step S30-4, the main CPU 201 performs normal symbol display time management processing. Here, a setting for opening the ordinary electric accessory 18 is performed.

  Note that the setting of the open state of the ordinary electric accessory 18 is different between when the game state is the normal game state and when the game state is the open state increasing game state (probability game state or short-time game state). It has become.

  In step S30-5, the main CPU 201 performs a normal power release process. Here, a process of opening the ordinary electric accessory 18 is performed.

  Specifically, when the gaming state is the normal gaming state, the variable wings 18a and 18b included in the ordinary electric accessory 18 are opened once for 0.2 seconds, and the gaming state is increased to an open state game. In the state (probability changing gaming state or short-time gaming state), the variable wings 18a and 18b provided in the ordinary electric accessory 18 are opened twice for 2.2 seconds.

  In step S30-6, the main CPU 201 subtracts “1” from the value of the passing memory counter when the normal symbol control state flag is a value (04) indicating the end of the normal symbol game. The main CPU 201 shifts the data stored in the normal symbol storage areas (“1” to “4”) to the normal symbol storage areas (“0” to “3”), respectively, and also stores the normal symbol storage. A value (00) indicating the check process is set in the normal symbol control state flag.

  The normal symbol storage area is assigned to the main RAM 203 and the random numbers for normal lottery extracted on condition that the game ball has passed through the passing gate 13 are stored in order from the normal symbol storage area “0”. This is a reserved storage area. Also, the random number for normal lottery stored in the normal symbol storage area (“1” to “4”) corresponds to the reserved storage displayed on the normal symbol storage LED, and the normal symbol storage area “0”. The random number value for the normal winning lottery stored in is used for the normal winning lottery in step S30-2.

  Next, the main process by the sub control circuit 300 and the command reception interrupt process executed to interrupt the main process when the command from the main control circuit 200 is received will be described. FIG. 9 is a flowchart showing a processing procedure of the command reception interrupt processing according to the present embodiment, and FIG. 10 is a flowchart showing a processing procedure of the main processing by the sub control circuit of the gaming machine according to the present embodiment.

  First, the command reception interrupt process will be described with reference to FIG. This command reception interrupt process is generated every time the sub control circuit 300 receives a command from the main control circuit 200.

  In step S201, the sub CPU 301 saves the information stored in the register in order to interrupt the currently executing process (main process described later).

  In step S202, the sub CPU 301 receives a command (for example, jackpot start command, count end command, jackpot end command, acquisition command, launch command, symbol command, variation pattern command, standby) received from the main CPU 201 via the command input port. Status command) is stored in the reception buffer area of the work RAM 303.

  In step S203, the sub CPU 301 restores the information saved in step S201 to the register. As a result, the suspended process can be resumed.

  Next, the main processing of the sub control circuit 300 of this embodiment will be described with reference to FIG.

  In step S210, the sub CPU 301 executes an initialization process for initializing various settings.

  Next, the command analysis processing in step S220 will be described with reference to FIG. FIG. 11 is a flowchart showing a processing procedure of command analysis processing.

  In step S220-1, the sub CPU 301 determines whether or not a command is stored in the reception buffer area. If the result of this determination is that a command is stored in the reception buffer area, the processing in step S220-2 is performed. On the other hand, if no command is stored in the reception buffer area, the command analysis processing is terminated.

  In step S220-2, the sub CPU 301 reads a command from the reception buffer area.

  In step S220-3, the sub CPU 301 determines whether or not the read command is a variable command. If the command is a variable command as a result of this determination, the process proceeds to step S220-5. If it is not a display pattern command (if it is another command), the process proceeds to step S220-4.

  In step S220-4, the sub CPU 301 determines whether or not the read command is a symbol command. As a result of the determination, if the command is a symbol command, the process proceeds to step S220-6. On the other hand, if it is not a symbol command (if it is another command), the process proceeds to step S220-7.

  In step S <b> 220-5, the sub CPU 301 sets effect data corresponding to the variation pattern included in the variation command in the work area of the work RAM 303.

  For example, when the read variation command is “h0”, the production data whose production display content is “normal variation” is set (see FIG. 13). If the read fluctuation command is “h5”, the effect data whose effect display content is “super reach A” is set.

  As a result, in the image control process to be described later, the decorative symbol variation display on the liquid crystal display device 21 is performed according to the variation pattern.

  In step S <b> 220-6, the sub CPU 301 sets effect data corresponding to the read symbol command in the work area of the work RAM 303.

  As a result, after the decorative symbol variation display is stopped in the image control process described later, the stop symbol included in the symbol command is displayed on the liquid crystal display device 21.

  For example, if the symbol command is any one of “z1” to “z4”, the sub CPU 301 draws a random number for decoration symbol determination in order to determine the ornament symbol, and the ornament symbol determination table of FIG. The stop symbol is determined on the basis of and the effect data is set based on the determination.

  Here, when the symbol command is “z1” and the extracted random number value is “6-7”, the decorative symbol “888” is determined, and the effect data is set based on the determination. When the symbol command is “z2” and the extracted random number value is “6-7”, the decorative symbol “777” is determined, and the effect data is set based on the determination.

  On the other hand, when the symbol command is “z0” and the variation command is “h0”, the left symbol, right symbol, and middle symbol are displayed based on the decorative symbol determination table (no reach) in FIG. The variable display result is determined separately, and control data is set based on the determination.

  For example, when the random number extracted to determine the left symbol is “1”, “2” is determined as the left symbol (see FIG. 15A), and then the right symbol is determined. If the extracted random number is “3”, “5” shifted by 3 symbols from the determined left symbol is determined as the right symbol (see FIG. 15B), and the middle symbol is determined. When the random number extracted for determination is “3”, “4” is determined as the middle symbol (see FIG. 15C), and these “left symbol”, “right symbol”, “middle symbol” are determined. Production data is set based on the determination of “design”.

  When the symbol command is “z0” and the variation command is other than “h0”, the left symbol, right symbol, middle symbol based on the decorative symbol determination table (reach with reach) in FIG. Are separately determined, and control data is set based on the determination.

  For example, if the random number extracted to determine the left symbol is “1”, “1” is determined as the left symbol (see FIG. 16A), and then the right symbol is already The same symbol as the determined left symbol is determined as the right symbol (see FIG. 16B), and if the random number extracted to determine the middle symbol is “3”, the determined left symbol “4” shifted by 3 symbols from the symbol is determined as the middle symbol (see FIG. 16C). Then, the effect data is set based on the determination of these “left symbol”, “right symbol”, and “middle symbol”.

  In step S220-7, the sub CPU 301 executes predetermined processing based on the read command. For example, effect data corresponding to the read command (for example, a standby state command) is set in the work area of the work RAM 303.

  Again, a description will be given with reference to FIG. In step 230, the sub CPU 301 as display control means confirms the effect data set in the command analysis process (FIG. 11), and executes the image display control process based on the effect data.

  For example, the sub CPU 301 instructs the VDP 305a to variably display decorative symbols according to the variation pattern included in the set representation data when the representation data related to the variation command is set in the command analysis processing. Change data over time. By executing the above instruction transmitted by the VDP 305a every predetermined time, the decorative symbol corresponding to the variation pattern is variably displayed in the decorative symbol display area.

  In step S240, the sub CPU 301 executes a voice control process.

  Specifically, in the audio control process, the sub CPU 301 confirms whether or not the effect data related to the sound is included in the effect data set in the command analysis process. As a result of the confirmation, if the production data related to the voice is included, the production data (hereinafter referred to as “voice production data”) is sent to the voice control circuit 306. The voice control circuit 306 causes the speakers 8a and 8b to output, for example, a sound signal for notifying the player of a predetermined gaming state based on the voice effect data.

  In step S250, the sub CPU 301 executes a lamp / LED lighting control process.

  Specifically, in the lamp / LED lighting control process, the sub CPU 301 confirms whether or not the effect data related to the lamp and the LED is included in the effect data set in the command analysis process. As a result of the confirmation, if the effect data related to the lamp or LED is included, the effect data (hereinafter referred to as “lamp effect data”) is sent to the lamp control circuit 307. Based on the lamp effect data, the lamp control circuit 307 causes the lamp / LED 39a to turn on / off in accordance with, for example, a predetermined lighting / extinguishing pattern.

  In this main process, the processes from step S220 to step S250 described above are repeated.

  In the special symbol determination process in the embodiment described above, there are two types of symbol selection tables (symbol selection table T1 and symbol selection table T2) as shown in FIG. Which of the two types of selection tables is to be referred to is determined depending on whether the gaming state is the normal gaming state or the probability variation gaming state. Then, depending on whether the determined special symbol is the first special symbol or the second special symbol, it is determined whether to shift to the probabilistic gaming state or the short-time gaming state after the end of the specific gaming state.

  However, the present invention is not limited to this, for example, as in the special symbol determination table shown in FIG. 17, it is confirmed whether the gaming state at the time of jackpot determination is the normal gaming state or the probable gaming state, and further, the short-time gaming state after the end of the specific gaming state Or whether to shift to a probable gaming state (first special symbol or second special symbol), and is referred from four types of symbol selection tables (symbol selection table T11 to symbol selection table T14). The symbol selection table to be determined may be determined.

  In this case, the main CPU 201 which is a symbol selection table determination unit confirms the gaming state at the time of jackpot determination. Next, it is determined by random number lottery whether the special symbol is to be the short and large bonus symbol (first special symbol) or the probability variable big bonus symbol (second special symbol). For example, when the gaming state at the time of jackpot determination is a probability variation gaming state and the result of the random number lottery is a value of “0-3” (in the case of “time bonus big hit”), the symbol selection in the symbol selection table T13 A special symbol is determined at a rate. If the result of random lottery is a value of “0 to 7”, the special symbol is determined as the H symbol.

  As described above, the main CPU 201 determines the special symbol after preliminarily selecting the probability variation big hit symbol and the time-shortage big hit with a random number value, so that the transition rate to the probability variation gaming state can be kept constant.

  Further, the main CPU 201, which is a special symbol determining means (symbol determining means), determines a special symbol based on the selection rate in the symbol selection table. However, the present invention is not limited to this, and the symbol determining means may be a normal symbol or a decorative symbol. It is good also as a means to determine.

  Further, the main CPU 201 which is the symbol selection table determination means determines the symbol selection table based on the big hit determination means determined by the big hit determination means, but is not limited to this. The symbol selection table may be determined in response to the transition to the gaming state, the establishment of a specific reach within a predetermined time after the end of the jackpot, or the winning by random number lottery processing for changing the selection rate.

  Further, in the present embodiment, the first special symbol is the hourly and big hit symbol “H, L”, and the second special symbol is the probability variation big hit symbol “F, A”. However, the present invention is not limited to this, and the first special symbol and the second special symbol may be a short-timeless big hit symbol and a probable variable big-hit symbol, respectively, or may be a short-timeless big hit symbol and a short-term big hit symbol, respectively.

  As described above, according to the present embodiment, the main ROM 202, which is the symbol selection table storage means, has the same selection rates for the first special symbol and the second special symbol, A plurality of symbol selection tables in which selection rates of at least some symbols are all different from each other are stored.

  For example, if the gaming state is a normal gaming state at the time of a big hit, the selection rate of the H symbol that is the first special symbol is 40%, and the selection rates of the F symbol and the A symbol that are the second special symbol are respectively 50% and 10%. On the other hand, when the game state at the time of the big hit is the probability variation game state, the selection rates of the L symbol and the H symbol which are the first special symbols are 10% and 30%, respectively, which is the second special symbol. The selection rate of the F symbol is 60%. That is, the selection rate of each symbol is different between the case where the game state at the time of the big hit is the normal gaming state and the case where the game state is the probability variation gaming state, but the selection rate between the first special symbol and the second special symbol. Are the same.

  This makes it possible to change the symbol selection rate according to the gaming state while maintaining the transition rate to the probability changing gaming state constant regardless of the gaming state.

  Further, as described above, since the selection rate between the first special symbol and the second special symbol does not change, the probability of transition to the probability-changing gaming state is kept constant regardless of the gaming state. Thereby, a game store can make a rough standard of the number of jackpots (for example, the number of jackpots is about 10 to 20 times during all day operation). Therefore, it is easy for the amusement store side to estimate the income and expenditure, and the management of the amusement store can be stabilized.

  In addition, since the transition to the probability variation gaming state is determined depending on the type of symbol, the relationship between the symbol and the probability variation is maintained, but even if the selection rate of the symbol is changed, the probability of transition to the probability variation gaming state is not changed. For example, the selection rate of the F symbol which is a probable big hit symbol is changed between when the big hit is judged in the normal gaming state and in the normal gaming state. The total selectivity does not change.

  It may be possible to process the decision process for determining the probability of change with a certain probability and the decision process for determining the symbol with a changeable probability, respectively, but this will naturally increase the processing load. That is, the relationship between the symbol and the rate of transition to the probable gaming state is lost. For example, a situation may occur in which the odd number symbol 777 does not change reliably among the jackpot symbols from 000 to 999. Therefore, the interest of the game will be reduced.

  However, as described above, the interest rate of the game can be maintained because the symbol selection rate is changed while the relevance between the symbol and the probability remains.

  Further, the symbol selection table is determined depending on whether the gaming state is the normal gaming state or the probability variation gaming state, the symbol selection rate changes, and the game content changes depending on the symbol. As a result, it is possible to provide new game characteristics according to the game state, and it is possible to further improve the interest of the game.

  In addition, since the symbol selection rate is determined from a plurality of symbol selection tables, the symbol selection rate changes. Then, a round closing condition is determined based on the selected symbol. Thereby, the new game nature that the closing condition of a round changes with the designs from which a selection rate changes can be provided.

  Furthermore, even if the round closing condition in the big hit gaming state can be changed depending on the design, the rate of transition to the probability changing gaming state that generates the big hit gaming state is constant. That is, even if the symbols that make the closing conditions advantageous to the player occur frequently, since the jackpot occurrence rate does not change, the total number of outgoing balls does not change so much. Thereby, the amusement store side does not need to consider the influence on the predictability of the balance.

  Further, the selection rate between the first special symbol and the second special symbol does not change depending on the gaming state at the time of jackpot determination. Therefore, only when it is in the normal gaming state at the time of jackpot determination, it is determined that a special symbol is suddenly changed into a certain probability change entry, and if it is in a probability change game state at the time of jackpot determination, it may not be determined as a sudden probability change entry symbol Is possible. For example, the selection rate of the A symbol which is a sudden probability change entry symbol in the normal gaming state at the time of the big hit determination is 10%, but the selection rate of the A symbol in the probability changing gaming state at the time of the big hit determination is 0%.

  Conventionally, in a gaming machine with sudden probability change, if sudden probability change has already occurred during the probability change game state, the player thinks that one big hit was consumed even though there was no prize ball, and suffered a sense of loss Could have been.

  However, as described above, according to the present embodiment, it is possible to provide a gaming machine that does not give the player the above-mentioned feeling of loss because there is a possibility that the player suddenly enters only the normal gaming state. It is.

  In the above description, the case where the present invention is applied to a gaming machine in which the main body of the pachinko gaming machine is attached to the gaming machine is described, but the present invention is not limited to this, and a pachislot gaming machine (slot Machine), sparrow ball, smart ball, or various game machines installed in a game center.
