Description

  The present invention relates to a ball game machine including, for example, two sets of special symbol display means and corresponding prize winning means.

  In the pachinko machine before the amendment to the current rules, more than one so-called special symbol display means cannot be mounted, and the stop symbol after the change of the special symbol display means becomes a big hit mode. It was possible to install only one big winning means to be opened. However, these regulations have been greatly relaxed due to the revision of the rules, and it is now possible to install up to two special symbol display means and special prize winning means.

  By the way, even if two sets of special symbol display means and corresponding prize winning means are installed on the pachinko machine based on the revised rules, the jackpot probability, the rush rate to probability fluctuation, and the jackpot occurrence for these two sets If there is the same ball, etc., the two functions of the same function are simply installed, and there is no relationship between them, so the synergistic effect of these two sets of special symbol display means cannot be expected. It cannot be improved.

In that respect, for example, in the pachinko machine described in Patent Document 1, the rate of entry into the probability variation is made different between the two special symbol display means, and the magnitude relationship is changed, so that the relationship between the two special symbol display means is related. It is said that it can have sex and can improve interest.
JP 2005-342262 A

  As in the pachinko machine described in the above-mentioned Patent Document 1, if the rush rate to the probability variation is made different between the two special symbol display means and the magnitude relationship is changed, a certain amount of space between the two special symbol display means. Although it can be related, it is doubtful whether the interest can be sufficiently improved by the synergistic effect of these two sets of special symbol display means.

  That is, it is clear that the player desires that a probabilistic jackpot will appear rather than a normal jackpot, but even when aiming for a promising jackpot, the player must first win a jackpot by changing a number of symbols. Therefore, with regard to which special symbol display means the player is aiming for the symbol variation, rather than the probability of entering the probability variation, the ease of variation, that is, which starting point is easier to win? This is considered to have a greater effect.

  In this way, only by changing the magnitude relationship of the rush rate to the probability variation in the two special symbol display means, it is possible to have a superficial relationship between the two special symbol display means, In a game, a player often ends up playing a game only aiming at a symbol variation on one of the special symbol display means side, and it can be said that the interest can be improved by the synergistic effect of these two special symbol display means. Absent.

  In view of such a conventional problem, the present invention surely changes the player's aim with respect to the symbol variation of the two special symbol display means according to the gaming state, thereby synergistic effects of the two sets of special symbol display means and the like. An object is to provide a ball game machine capable of exhibiting the above and capable of truly improving interest.

  The present invention includes first and second special symbol display means 23a and 23b for variably displaying the first and second special symbols on the basis that the first and second variation start conditions are satisfied, and the first and second special symbols. First and second profit state generating means 65a and 65b for generating the first and second profit states based on the fact that the stop symbol after the change of the special symbol display means 23a and 23b becomes a jackpot mode predetermined by lottery. And a special game state generating means 67 for generating a special game state in a predetermined period after the occurrence of the first and second profit states, wherein the second profit state is more in the first profit state. The average profit that the player can obtain is set to be larger than the profit state, and the second variation start condition is more easily established in the special game state than in the normal game state other than the special game state. Configured to be It is intended.

  According to the present invention, as a first step, the player is first caused to change the first special symbol so as to generate a special gaming state, and the first special symbol becomes a jackpot and the first profit state is generated. Then, when a special gaming state occurs, an incentive can be given so as to aim for a change in the second special symbol so as to generate the second profit state as the second stage. Thereby, the player's aim with respect to the symbol variation of the two special symbol display means 23a, 23b can be changed reliably depending on the gaming state, and the synergistic effect of the two sets of special symbol display means 23a, 23b, etc. is exhibited, It is possible to truly improve interest.

  The variable display means 12 is arranged, for example, on the upper side of the game area 11 and in the approximate center in the left-right direction. The display case 17 is mounted on the game board 9 from the front side, and is arranged in the approximate center of the display case 17. In addition, for example, a liquid crystal variable display unit 18 is provided. The display case 17 is provided with normal symbol display means 21, normal reserved number display means 22, first and second special symbol display means 23a and 23b, first and second special reserved number display means 24a and 24b, and the like. Yes. The variable display unit 18 can display various moving images, still images, and the like, and constitutes first and second effect symbol display means 25a and 25b.

  The normal symbol start means 13 is for starting the symbol variation by the normal symbol display means 21, and is composed of, for example, a passing gate through which a game ball can pass, and a normal symbol start detection switch for detecting the passed game ball. 26. In the present embodiment, the normal symbol starting means 13 is arranged on the right side of the variable display means 12.

  The normal symbol display means 21 is for variably displaying normal symbols, and is composed of, for example, two light emitters (for example, LEDs) corresponding to two types of normal symbols “O” and “X”. Under the condition that the normal symbol start detection switch 26 of the symbol start means 13 detects the game ball, the two light emitters blink alternately for a predetermined time, and the hit acquired when the normal symbol start detection switch 26 detects the game ball. When the determination random number value matches a predetermined hit determination value, the light emitter on the “◯” side corresponding to the hit mode is in a light-emitting state, otherwise “×” corresponding to the off mode The blinking ends when the side light emitter emits light.

  Further, when the normal symbol starting means 13 detects a game ball during the fluctuation display of the normal symbol display means 21, the hit determination random number value acquired at the time of detection detects a predetermined upper limit reserved number, for example, four Is stored as a limit and, for example, the normal holding number display means 22 made of the same number of light emitters as the upper limit holding number displays the stored number of random numbers for hit determination (hereinafter referred to as normal holding number) by the number of light emission, The player is informed of the number of normally reserved items at that time.

  The first and second special symbol starting means 14a and 14b are for starting symbol variation by the first and second special symbol display means 23a and 23b, and are constituted by winning means capable of winning a game ball. The game balls won on the front side of the game board 9 are guided to the back side of the game board 9, and the game balls are detected by the first and second special symbol start detection switches 27a and 27b, respectively.

  The second special symbol starting means 14b is an open / close-type winning means having a pair of left and right opening / closing claws 28 that can be switched between an open state in which a game ball can be won and a closed state in which a game ball cannot be won. When the normal symbol after 21 changes is in a hit state, it changes to the open state a predetermined number of times for a predetermined time based on any of a plurality of types of opening / closing patterns.

  In the present embodiment, the first special symbol starting means 14 a is arranged on the left side of the variable display means 12, and the second special symbol starting means 14 b is arranged below the variable display means 12.

  Each of the first and second special symbol display means 23a and 23b is composed of one or a plurality of display means such as a seven-segment type display means capable of variably displaying each one of the first and second special symbols. The first and second special symbol start means 14a and 14b of the first and second special symbol start means 14a and 14b respectively display the first and second special symbols for a predetermined time on condition that a game ball is detected. Then, when the first and second jackpot determination random numbers acquired when the game balls are detected by the first and second special symbol start detection switches 27a and 27b match the predetermined jackpot determination value, a predetermined jackpot In the mode, in other cases, it is stopped in the off mode.

  For the first and second special symbols, numeric symbols, alphabet symbols, character symbols, and other symbols can be used as appropriate. In this embodiment, ten kinds of numerical symbols “0” to “9” and symbol symbols “−” are used for the first and second special symbols, and “0” to “9” constitute a jackpot mode. The jackpot symbol, “−”, is set as a losing symbol constituting the detaching mode.

  Furthermore, in this embodiment, among the numbers “0” to “9”, the odd symbol is a specific symbol, the even symbol is a normal symbol, the jackpot mode by the specific symbol is the specific jackpot mode, and the jackpot mode by the normal symbol is normal The jackpot mode.

  Further, when the first and second special symbol starting means 14a and 14b detect the game ball during the first and second special symbol fluctuation display or during the first and second profit states described later, the detection is made. The first and second jackpot determination random numbers obtained from time to time are stored up to a predetermined upper limit number of reservations, for example, four, and the first and second special reservations are made up of the same number of light emitting means as the upper limit reservation number, for example. The number display means 24a and 24b store the number of first and second big hit determination random numbers related to the first and second special symbol display means 23a and 23b according to the number of emitted lights (hereinafter referred to as first and second special reserved numbers). Is displayed, and the player is notified of the first and second special reserve numbers at that time.

  The first and second effect symbol display means 25a and 25b are synchronized with the change display of the first and second special symbols by the first and second special symbol display means 23a and 23b in time and the first and second effect effects are displayed. In this embodiment, the substantially left half of the variable display unit 18 is used as a display area for the first effect design display means 25a, and the substantially right half is used as a display area for the second effect design display means 25b. Assigned. Note that, for example, the positions and sizes of the display areas of the first and second effect symbol display means 25a and 25b on the variable display unit 18 may be changed according to the gaming state.

The first and second effect symbols are arranged in a predetermined order such as left, right, and middle so that the first and second effect symbols start to change and stop at the same time as the first and second special symbols change. It is supposed to stop.

  For the first and second effect designs, numeric symbols, alphabet symbols, character symbols, and other symbols can be used as appropriate. In this embodiment, ten types of numerical symbols “0” to “9” are used for the left, middle, and right production symbols, respectively, such as “6/6/6”, “7/7/7”, etc. A case where all the symbols are arranged in the same symbol is a jackpot mode, and a case where at least one symbol is different is a missed mode.

  The stop symbols after the first and second effect symbols are changed by the first and second effect symbol display means 25a and 25b are the first and second special symbols by the first and second special symbol display means 23a and 23b. Is a big hit mode consisting of the same number symbols as the first and second special symbols, and when the first and second special symbols are stopped in the off mode, it is an arbitrary off mode. For example, when the first special symbol is stopped at “7”, the first effect symbol is stopped at “7 · 7 · 7”, and when the first special symbol is stopped at “−”, the first effect symbol is stopped. Is stopped in any disengagement mode such as “3, 4, 5”.

  Also, like the first and second special symbols, among the numbers “0” to “9”, the odd symbol is the specific symbol, the even symbol is the normal symbol, and the big hit mode by the specific symbol is the specific jackpot mode, the normal symbol The jackpot mode according to is normally the jackpot mode.

  The first and second large winning means 15a and 15b are open / close winning means provided with opening and closing plates 29a and 29b that can be switched between an open state in which a game ball can be won and a closed state in which a game ball cannot be won. When the first and second profit states occur on the basis of the fact that the first and second special symbols after the fluctuation of the second special symbol display means 23a and 23b are in a big hit mode, the opening and closing plate 29 is opened in a plurality of types. According to any of the patterns, the game ball is released to the front side, and the game ball dropped on it is awarded to the inside.

  The game balls that have won the first and second big winning means 15a and 15b are guided to the back side of the game board 9 and detected by the first and second count switches 30a and 30b, respectively.

  In the present embodiment, the first big winning means 15a is arranged below the variable display means 12 and the second special symbol starting means 14b, and the second big winning means 15b is arranged below the normal symbol starting means 13, respectively. .

  The normal random number generation processing means 41 is configured to repeatedly generate a hit determination random number used for determining whether or not the changed normal symbol is set to be a hit mode at predetermined time intervals.

  The normal start opening check processing means 42 performs processing based on the detection of the game ball by the normal symbol start means 13, and the normal random number generation processing means 41 is provided on condition that the normal symbol start means 13 detects the game ball. A single random number value for hit determination is obtained, and the random number value for hit determination is stored in the normal random number storage means 43 with a predetermined upper limit reserved number (for example, four) as a limit. .

  The number of random numbers for hit determination (ordinary reserved number) stored in the normal random number storage means 43 is displayed by the normal reserved number display means 22 as the number of LEDs emitted.

  The normal symbol processing unit 44 performs processing related to the normal symbol variation display, and includes a hit determination unit 51, a normal stop symbol selection unit 52, a variation time selection unit 53, and the like.

  The hit determination means 51 determines whether or not the stop symbol after the fluctuation of the normal symbol is used as the hit mode. The normal symbol display means 21 is in a state where it can be displayed in a variable manner, and one is stored in the normal random number storage means 43. On the condition that the above-mentioned hit determination random number value is stored (the number of normal holdings is 1 or more), the hit determination random value stored in the normal random number storage means 43 is taken out and the hit determination is performed. It is configured to make a hit / miss determination according to whether or not the random number for use matches a predetermined hit determination value.

  In the present embodiment, as shown in FIG. 5, the number of hit determination values used for the hit determination by the hit determination means 51 is different between the special game state described later and the other normal game state. The winning probability (for example, 1 / 1.3) in the special gaming state is set higher than the winning probability (for example, 1/10) in the normal gaming state.

  The normal stop symbol selection means 52 selects the type of stop symbol after the normal symbol fluctuates. In this embodiment, only one type of symbol corresponds to the hit mode and the miss mode. Therefore, based on the hit / miss judgment result by the hit judgment function, “○” In the case of determination of detachment, “×” is selected uniformly.

  The fluctuation time selection means 53 is for selecting the fluctuation time of the normal symbol. In the present embodiment, as shown in FIG. 5, the variation time (for example, 2.7 seconds) in the special gaming state is set to be shorter than the variation time (for example, 27 seconds) in the normal gaming state. . In addition, you may provide multiple types of fluctuation time of this normal symbol for every gaming state.

  The normal profit state generating means 45 is the second special symbol when the determination result by the hit determining means 51 of the normal symbol processing means 44 is a hit determination and the stop symbol after the fluctuation of the normal symbol display means 21 is in a hit state. The starting means 14b is changed to an open state according to any of a plurality of types of opening / closing patterns.

  In the present embodiment, as shown in FIG. 5, the normal opening / closing pattern (for example, 0.2 seconds × opening once) and the opening time and / or the number of opening times are set to be longer than the normal opening / closing pattern. Two types of opening / closing patterns (for example, 2 seconds × 3 times opening) are set, and the normal opening / closing pattern is selected during the normal gaming state, and the special opening / closing pattern is selected during the special gaming state. Yes. A plurality of opening / closing patterns of the second special symbol starting means 14b may be provided for each gaming state.

  The normal symbol display control means 46 controls the display of the normal symbol display means 21 based on the normal symbol processing by the normal symbol processing means 44. The normal symbol display means 21 is in a state in which the normal symbol display means 21 can be variably displayed and the normal random number storage means. On the condition that one or more hit determination random number values are stored in 43 (the number of normal holdings is 1 or more), the normal symbol display means 21 starts to change the normal symbol, and the change time selection means 53 The fluctuation of the normal symbol is stopped at the stop symbol selected by the normal stop symbol selecting means 52 based on the passage of the fluctuation time selected in step (b).

  The first and second special random number creation processing means 61a and 61b include the jackpot determination random number used for determining whether or not the first and second special symbols after change are to be the big hit mode, and the special symbol after change is Configured to perform a special random number creation process that repeatedly generates a random number for a big hit symbol used for selection of a stop symbol in the case of a big hit mode, a random number for variation pattern selection used for selection of a special symbol variation pattern, and other predetermined random numbers Has been.

  The first and second special start opening check processing means 62a and 62b perform processing based on the detection of the game ball by the first and second special symbol start means 14a and 14b. The first and second special symbol start means On the condition that 14a and 14b detect a game ball, the jackpot determination random number value and the jackpot symbol random number value created by the first and second special random number creation processing means 61a and 61b are obtained one by one. First and second special random number storage means 63a, 63b with a predetermined upper limit reserved number (for example, four each) as a limit for a determination random number value and a winning design random value (an example of first and second detection information). It is comprised so that it may memorize.

  The first and second special symbol processing means 64a and 64b perform processing related to the variable display of the first and second special symbols, and the first and second big hit determination means 71a and 71b and the first and second special stops. Symbol selection means 72a, 72b, first and second variation pattern selection means 73a, 73b and the like are provided.

  The first and second jackpot judging means 71a and 71b are jackpot judgments as to whether or not the changed first and second special symbols are to be jackpots by random lottery, and the first and second special symbol displays. The means 23a, 23b can be displayed in a variable manner, and one or more jackpot determination random numbers are stored in the first and second special random number storage means 63a, 63b (the number of special reserves is one or more. ) Is taken out, the jackpot determination random number value stored earliest in the first and second special random number storage means 63a, 63b is taken out, and whether or not the jackpot determination random number value matches a predetermined jackpot determination value. Depending on whether or not, the jackpot / outage determination is performed.

  The first and second special stop symbol selection means 72a and 72b select the stop symbol after the fluctuation of the first and second special symbols, and the first and second big hit determination means 71a and 71b Based on the determination result and the jackpot symbol random number value stored together with the jackpot determination random number value in the first and second special random number storage means 63a, 63b, the stop symbol after the fluctuation of the first and second special symbols Is configured to select.

  For example, when the determination result by the first and second jackpot determination means 71a and 71b is a jackpot determination, any one of “0” to “9” that is a jackpot symbol is selected based on the random number value for the jackpot symbol If the determination result by the first and second big hit determination means 71a, 71b is a determination of losing, “−” which is a losing symbol is selected.

  The first and second variation pattern selection means 73a and 73b select variation patterns of the first and second effect symbols, and are based on the determination result of big hit / loss from the first and second big hit determination means 71a and 71b. Thus, one of a plurality of types of special symbol variation patterns is selected.

  The first and second profit state generating means 65a and 65b are jackpot determinations based on the determination results by the first and second jackpot determination means 71a and 71b, and the first and second special symbol display means 23a and 23b are stopped after fluctuation. The first and second profit states that are advantageous to the player are generated on the basis that the symbol becomes a big hit mode such as “7”.

  The first and second profit states are those in which the first and second grand prize winning means 15a and 15b are opened according to a predetermined opening pattern, and one or a plurality of types of opening patterns are provided. One of them is selected by the second profit state generating means 65a, 65b.

  In the present embodiment, as shown in FIG. 4, two types of opening patterns A and B are set in the first profit state, and one type of opening pattern C is set as the second profit state. The 1-profit state selection means 74a sets the release pattern A to any one of “4” to “9” when the stop symbol after the change of the first special symbol display means 23a is any of “0” to “3”. In this case, the opening pattern B is selected.

  The opening pattern A in the first profit state is set so that the operation of releasing the first big winning means 15a for 0.2 seconds is performed for two rounds. This opening pattern A is an example of a specific opening pattern, and since the opening time of one time is as short as 0.2 seconds and the number of rounds is as few as two rounds, the possibility that a game ball will win during the opening is extremely It is getting smaller. In other words, the average pitch in the case of the open pattern A is almost zero, and the direct profit that the player can obtain is extremely small.

  In the opening pattern B in the first profit state, a predetermined number (9 in this case) of game balls wins after a predetermined time (in this case, 28 seconds) has elapsed since the opening of the first big winning means 15a. The closing operation is set to perform a predetermined number of rounds (here, 13 rounds). In the case of this open pattern B, assuming that there are 15 prize balls for one winning to the first big winning means 15a, in most cases 9 × 15 × 13 = 1755 only when the player continues the normal firing operation. As compared with the open pattern A, the direct profit that the player can obtain can be expected to be significantly higher.

  Here, the average number of pitches in the case of the first profit state (an example of the average profit that the player can obtain) is zero average pitches in the case of the open pattern A, average pitches in the case of the open pattern B Is 1755, (1755 × 6 + 0 × 4) / 10 = 1053.

  In the opening pattern C in the second profit state, a predetermined number (9 in this case) of game balls wins a predetermined time (in this case, 28 seconds) after the second big winning means 15b is opened or until that time. It is set so that the closing operation is performed for a predetermined number of rounds (here, 15 rounds). According to this open pattern C, if the number of winning balls for one winning to the second big winning means 15b is 15, the player only normally continues the firing operation, and in most cases 9 × 15 × 15 = 2025 balls can be expected, and the direct profit that the player can obtain is even greater than the opening pattern B.

  Comparing the average number of starts in the first profit state and the second profit state (average profit obtained by the player), the second profit state is about 2000 against about 1000 in the first profit state. The average profit that the player can obtain in the state is larger than that in the first profit state.

  The first and second special symbol display control means 66a and 66b are based on the first and second special symbol processing by the first and second special symbol processing means 64a and 64b, respectively. 23b, the first and second special symbol display means 23a and 23b can be variably displayed, and the first and second special random number storage means 63a and 63b have one or more jackpot determination disturbances. The first and second special symbols are changed by the first and second special symbol display means 23a and 23b on the condition that a numerical value is stored (the number of special reservations is 1 or more). Selected by the first and second special stop symbol selection means 72a and 72b based on the passage of the fluctuation time corresponding to the first and second fluctuation patterns selected by the second fluctuation pattern selection means 73a and 73b. No. with stop symbol , And is adapted to stop the fluctuation of the second special symbol.

  The special gaming state generating means 67 is for generating a special gaming state advantageous to the player for a predetermined period after the occurrence of the first and second profit states, for example, a short-time gaming state or a probability variation gaming state. When the second special symbol becomes a big hit mode and the first and second profit states occur, after the end of the first and second profit states, for example, an ordinary symbol consisting of even numbers In the case of a big hit mode, a short-time gaming state is generated, and in the case of a specific jackpot mode consisting of odd numbers, a probability variation gaming state is generated.

  During the short-time gaming state, regarding the first and second special symbols, the variation time of the first and second special symbol display means 23a, 23b is switched to a shortened variation time shorter than the normal variation time, respectively, The hit probability is changed from the normal probability (for example, 1/10) to the high probability (for example, 1 / 1.3), the variation time from the normal variation time (for example, 27 seconds) to the shortened variation time (for example, 2.7 seconds), the second The opening / closing pattern of the special symbol starting means 14b can be switched from a normal opening / closing pattern (for example, 0.2 seconds × open once) to a special opening / closing pattern (for example, 2 seconds × 3 times).

  In addition, there are two types of short-time game states with different durations, and as shown in FIG. 4, for example, a short-time game that occurs when a normal big hit mode with either “0” or “2” is achieved. State a is a short game state b that occurs when the first and second special symbols fluctuate 50 times, for example, when a normal big hit state with any of the symbols “4”, “6”, and “8” occurs. The first and second special symbols are continuously ended until they change 100 times.

  In addition, during the probabilistic gaming state, the probability that the first and second special symbols will be a big hit mode is switched from the normal probability (for example, a low probability of 1/350) to the high probability (for example, 1/35). The same processing is performed.

  The control command transmitting means 68 is for transmitting a predetermined control command to the sub-control board side such as the effect control board 32 by one-way communication and giving a control command. The first and second special symbol processing means 64a, Based on the first and second special symbol processing by 64b, first and second variation pattern designation commands for designating the first and second variation patterns, and first and second for designating the first and second special stop symbols. In addition to sending a special stop symbol designating command and first and second variable stop designating commands to specify the stop of the first and second special symbols to the effect control board 32 side, for example, the first and second profit states, the special game state Based on various gaming states such as the above, the control command for the image, sound and lamp is transmitted to the effect control board 32 side.

  The effect control board 32 is for controlling various effect means such as the first and second effect symbol display means 25a and 25b, the sound output means 81, the lamp means 82, and the first and second effect symbol display control means. 83a, 83b, sound control means 84, lamp control means 85, and the like.

  The first and second effect symbol display control means 83a and 83b perform display control of the first and second effect symbol display means 25a and 25b. When the first and second effect symbol display control means 83a and 83b receive the first and second variation pattern designation commands from the main control board 31 side, the first and second effect symbols are displayed with the designated variation pattern. When the first and second variation stop designation commands are received, the stop selected based on the first and second special stop symbol designation commands and the first and second variation pattern designation commands is received. The variation of the first and second effect symbols is stopped by the symbol.

  The audio control unit 84 performs audio output control of the audio output unit 81 such as a speaker, and outputs a predetermined sound effect or the like from the audio output unit 81 based on an audio control command from the main control board 31 side. It has become.

  The lamp control means 85 performs display control of the lamp means 82 and the like, and causes the lamp means 82 and the like to emit light in a predetermined pattern based on a lamp control command from the main control board 31 side.

  In this pachinko machine as described above, in order for the player to obtain a great profit (prize ball) as the final goal, the first and second big winning means 15a and 15b can be placed within the shortest possible time. It is necessary to open for a long time.

  Here, when comparing the first profit state in which the first big winning means 15a is opened and the second profit state in which the second big prize means 15b is opened, as shown in FIG. 4, the first profit state is opened. There are two types of patterns A and B, and for the open pattern A of them, the average number of balls is close to 0, whereas the second profit state is only the open pattern C and the average ball number is the first. More than the open pattern B in the profit state.

  That is, when the second profit state occurs, the player can almost certainly acquire a large number of prize balls, whereas when the first profit state occurs, the player is lucky to select the opening pattern B. Even if it is done, the number of prize balls that can be obtained is smaller than in the case of the second profit state, and if the opening pattern A is selected unfortunately, almost no prize balls can be obtained.

  In this way, in this pachinko machine, if only the profits obtained by the player when the first and second profit states are assumed to be compared, the average number of balls in the first profit state is about 1000 On the other hand, the average number of balls in the second profit state is about 2000, and it can be said that the second profit state is more advantageous to the player than the first profit state.

  In reality, however, the first profit state and the second profit state are not the same in the rate of change of the first special symbol and the second special symbol, which are the premise of their occurrence, and their relationship depends on the gaming state It is going to change.

  That is, since the first special symbol starting means 14a for starting the variation of the first special symbol is constituted by a non-opening / closing type winning means, the difficulty level of the winning is constant regardless of the gaming state.

  On the other hand, the second special symbol starting means 14b for starting the variation of the second special symbol is an open / close-type winning means, and is opened only when the normal symbol is in a winning mode, and the probability of hitting the normal symbol The variation time and the opening / closing pattern of the second special symbol starting means 14b vary depending on the gaming state.

  For example, as shown in FIG. 5, during the normal gaming state, the normal symbol hit probability is a normal probability (eg, 1/10), the change time is a normal change time (eg, 27 seconds), 2 While the opening / closing pattern of the special symbol starting means 14b is a normal opening / closing pattern (for example, 0.2 seconds × opened once), during the special gaming state after the first and second profit states, The probability is a high probability (for example, 1 / 1.3), the variation time is a shortened variation time (for example, 2.7 seconds), and the opening / closing pattern of the second special symbol starting means 14b in the hit state is a special opening / closing pattern. (For example, 2 seconds × 3 times open).

  Thus, during the normal gaming state, the difficulty of winning the second special symbol starting means 14b is extremely high, and thus the rate of change of the second special symbol is very low, while the second special symbol starting means 14b has a very low rate of change. The difficulty of winning the winning of the symbol starting means 14b is greatly relaxed, and the second special symbol is likely to fluctuate.

  From the above, in order to obtain a large profit with this pachinko machine, the player does not aim for the occurrence of the second profit state immediately from the normal gaming state immediately after the start of the game, but as shown in the upper column of FIG. First, in order to generate a special gaming state and reduce the difficulty of winning a prize to the second special symbol starting means 14b, the first special symbol starting means 14a having a lower difficulty of winning than the second special symbol starting means 14b. It is desirable to perform a launch operation aiming at the left side of the game area 11 so as to win a prize.

  Even if the second special symbol becomes a big hit mode and the first profit state occurs, for example, when the opening pattern A is selected, almost no winning to the first big winning means 15a can be expected, and the player There is no direct benefit. However, a special gaming state occurs after the end of the first profit state, the probability of hitting the normal symbol becomes high and the variation time is shortened, and the opening / closing pattern of the second special symbol starting means 14b is specially opened / closed. Since it becomes a pattern, the difficulty of winning a prize of the second special symbol starting means 14b decreases. Therefore, as shown in the lower column of FIG. 6, the player performs a launch operation aiming at the right side of the game area 11 in order to change the normal symbol as a stage before winning the second special symbol starting means 14b from here. Just do it.

  When the game ball passes through the normal symbol starting means 13 and the normal symbol fluctuates and stops in a hit state, the second special symbol starting means 14b is opened for a longer time than the normal opening / closing pattern (for example, 0.2 seconds × opened once). Is opened in a special opening / closing pattern that is long and has a large number of opening / closing operations, so that the game ball easily wins the second special symbol starting means 14b, and the second special symbol fluctuates.

  In addition, if the special gaming state at that time is a probability-changing gaming state, it becomes a big hit mode with a higher probability than usual, the second profit state occurs, and the second big winning means 15b is released according to the opening pattern C. The player can surely earn a great profit.

  As described above, the pachinko machine of the present embodiment is set so that the average profit that the player can obtain in the second profit state is larger than that in the first profit state, and the special game is more than in the normal game state. Since it is configured so that winning in the second special symbol starting means 14b is easier during the state, the first special symbol changes to generate a special gaming state as a first step for the player. When the first special symbol becomes a big hit mode and the first profit state occurs and the special gaming state occurs, the second special symbol is changed to generate the second profit state as the second stage. Incentives that can be aimed at can be given.

  Thereby, the player's aim with respect to the symbol variation of the two special symbol display means 23a, 23b can be changed reliably depending on the gaming state, and the synergistic effect of the two sets of special symbol display means 23a, 23b, etc. is exhibited, It is possible to truly improve interest.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the second variation start condition may be established more easily in the special game state than in the normal game state. For example, the normal symbol is omitted and the second special symbol starter 14b is set in the normal game state. You may comprise so that opening time and / or the frequency | count of opening may become large in the special game state rather than inside.

  Further, for example, both the first and second special symbol starting means 14a and 14b may be open / close winning means, and the opening time and / or the number of opening times may be relatively changed.

  In the embodiment, the first special symbol display means 23a and the second special symbol display means 23b are configured to be able to change in parallel, but either one of the first and second special symbol display means 23a and 23b is used. You may comprise so that the other symbol fluctuation | variation may not be started during a fluctuation | variation.

  In this case, when both the first and second special reserved numbers are 1 or more, the symbol variation of the second special symbol display means 23b is prioritized over the symbol variation of the first special symbol display means 23a. It may be configured.

  In the embodiment, the first special symbol starting means 14a is arranged on the left side of the gaming area 11 and the normal symbol starting means 13 is arranged on the right side of the gaming area 11, so that the player can easily aim and shoot according to the gaming state. Although configured, the arrangement of the game parts in the game area 11 is arbitrary. For example, the first special symbol starting means 14a is arranged below the variable display means 12 together with the second special symbol starting means 14b so that the game ball on the left side of the game area 11 is guided toward the center by the arrangement of the game nails. It may be.

  It is not always necessary that the first and second special symbols and the first and second effect symbols are variably displayed in time synchronization. For example, the first and second effect symbol display means 25a and 25b are omitted. May be.

  You may comprise a 1st special symbol and a 2nd special symbol so that the other cannot start a fluctuation | variation during one fluctuation | variation.

  One winning prize means may be opened depending on the first and second profit states. That is, it may be configured to open a common prize winning means in the first profit state and the second profit state.

  The first special symbol display means 23a and the second special symbol display means 23b may adopt different types of display devices. For example, the first special symbol display means 23a may be a liquid crystal type and the second special symbol display means 23b may be a drum type display means.

  The setting contents such as the opening pattern of the first and second profit states and the opening / closing pattern of the second special symbol starting means 14b are arbitrary.

  The present invention is not limited to pachinko machines and can be similarly implemented in various ball game machines such as an arrangement ball machine and a sparrow ball game machine.
