Description

  The present invention relates to a gaming machine that controls the contents of effects of a gaming machine that performs a lottery lottery every time a game ball wins a predetermined starting point on a gaming board, an effect control method and an effect control program executed by the gaming machine.

  Conventionally, there is a so-called latent probability variation jackpot game. This is a function that makes it difficult for the player to determine whether or not the player has transitioned to the high probability state because the player has not been clearly notified of the transition from the low probability state to the high probability state. This latent probability variation jackpot game is generally configured such that after a change to the special mode, the symbol changes by a predetermined number of changes, and then returns to the normal mode (for example, , See Patent Document 1 below).

  In addition, the change to the special mode is not only when winning the latent probability variation jackpot, but also when winning the small hit game in the so-called low probability state, just as when winning the latent probability variation jackpot game, There was a change to the special mode, and thereafter, the same number of changes as in the case of the latent probability change jackpot game was changed, and then the normal mode was restored. As a result, only a small hit game is won in the low probability state, so even though the low probability state continues, it wins as if the latent probability fluctuation jackpot, changes to the high probability state, the high probability state continues It was configured to reinforce the player's expectation by performing as if he were doing it.

FIG. 3 is an explanatory diagram showing a functional configuration of the main control unit. As shown in FIG. 3, the main control unit 201 includes a receiving unit 300, a lottery unit 301, a setting unit 302, a table 303, a variation count counting / determination unit 304, a mode changing unit 305, and a variation pattern table. 306, a transmission unit 307, and a probability variation processing unit 308.

  The receiving unit 300 receives a winning signal from the first starting winning port SW221 or the second starting winning port SW222, and sends the received winning signal to the lottery unit 301. Further, the receiving unit 300 sends the received winning signal to the variation counting / determination unit 304.

  The lottery unit 301 executes a jackpot lottery every time the receiving unit 300 receives a winning signal, and receives a lottery result including winning a small hit game or 2R latent probability variation jackpot game, a setting unit 302, a mode change unit 305, the probability variation processing unit 308 and the like are transmitted. Therefore, based on the lottery result of the lottery unit 301, the low probability state or the high probability state is set.

  A plurality of setting units 302 are provided with reference to the table 303 when the lottery result (command) received from the lottery unit 301 is a command for instructing execution of a small hit game or a 2R latent probability variation big hit game. One of the types of variation times is selected from the types of variation times, and is set as the number of variation times of the symbols to be executed in the special mode.

  The variation count counting / determination unit 304 receives the winning signal from the receiving unit 300, thereby counting the number of symbol variations after the mode is changed (the number of winnings), and the variation number is a variation set in advance for the symbol. Determine whether the number of times has been reached.

  The mode change unit 305 changes from the normal mode to the special mode based on the lottery result (command) received from the lottery unit 301. At that time, a special mode table to be described later is read from the variation pattern table 306. The mode changing unit 305 receives a signal indicating that the predetermined number of fluctuations has elapsed from the fluctuation number counting / determination unit 304 and changes the mode from the special mode to the normal mode. Along with the change to the normal mode, the normal mode table is read from the fluctuation pattern table 306.

  Here, the change to the normal mode can be made, for example, by displaying the background for the normal mode stored in a predetermined storage area (not shown). At that time, with reference to the normal mode table (see FIG. 5A) of the table 303, one of the types of the number of fluctuations is selected by lottery. The special mode can be changed, for example, by displaying the background for the special mode stored in a predetermined storage area (not shown). At that time, with reference to a table for special mode (see FIG. 5A) in the table 303, one of the types of the number of fluctuations is selected by lottery.

  The transmission unit 307 includes an instruction signal related to the lottery result from the lottery unit 301, an instruction signal related to information set in the setting unit 302 from the setting unit 302, an instruction signal related to the count / determination result from the variation count / determination unit 304, An instruction signal related to the mode change from the mode change unit 305 is transmitted to the effect control unit 202. The effect control unit 202 receives these various instruction signals, and performs display control of displayed contents in the image display unit 104 based on the various display instruction signals. The effect control unit 202 repeatedly displays the special symbol for the predetermined number of fluctuations in the state changed to the special mode.

  The probability variation processing unit 308 receives the command signal from the receiving unit 300 and performs probability variation processing. Specifically, in the case of the latent probability variation, it is possible to shift to the latent probability variation gaming state (high probability state) by turning on the latent probability variation flag.

  For example, the CPU 241 uses the RAM 243 as a work area for the functional units of the reception unit 300, the lottery unit 301, the setting unit 302, the variation count / determination unit 304, the mode change unit 305, the transmission unit 307, and the probability variation processing unit 308. However, the functions can be realized by executing various programs stored in the ROM 242. The functions of the table 303 and the fluctuation pattern table 306 can be realized by the ROM 242 or the RAM 243.

(Contents of special mode)
Next, an example of the contents of the special mode will be described. The special mode is a mode in which an effect different from the normal mode is performed. In addition, the special mode may include not only an effect different from that in the normal mode but also one that performs the following processing.

  FIG. 4 is an explanatory diagram showing an example of the data structure of the variation pattern table. FIG. 4 shows a variation pattern table 306 regarding a variation pattern (variation time) with respect to the number of holdings. In the normal mode, when the number of holdings is “0” or “1”, the variation time is “12 (seconds). ". Similarly, in the normal mode, when the hold number is “2”, the change time is “8 (seconds)”, and when the hold number is “3” or “4”, the change time is “4 (seconds)”. It is shown that. This is because in the normal mode, when the number of holdings is large, the holding balls are consumed as soon as possible.

  On the other hand, in the case of the special mode, the variation time is uniformly “10 (seconds)” regardless of the number of holds. This is in order to show the player the special mode effect for as long as possible. Further, by setting the same variable time regardless of the number of holdings, it is possible to execute continuous production contents without considering the number of holdings.

  Further, in the special mode, not only the variation time for each holding number is changed from the normal mode, but also, for example, the probability of reaching may be changed in the normal mode. Specifically, for example, the probability of reaching during the normal mode execution may be set to “1/10”, and the probability of reaching during the special mode execution may be set to “1/30”.

(Table contents)
FIG. 5A is an explanatory diagram of an example of the data configuration of the table 303. FIG. 5B is an explanatory diagram showing a comparison of the number of symbol changes in the special mode when winning a small hit game in a low probability state and winning a 2R latent probability variation big hit game.

  In FIG. 5A, “A” to “J” are provided as an example of the types of symbol variation counts, which is a pattern group composed of a plurality of patterns having different symbol variation counts. Actually, more types of symbol variations are prepared, but for convenience of explanation, 10 types “A” to “J” are used. Then, when shifting from the normal mode to the special mode, one of the patterns “A” to “J” is selected from the table 303 which is a table storing a pattern group including a plurality of patterns having different numbers of symbol variations, Based on the selected pattern, the pattern is changed as many times as the number of changes in the pattern. And after performing the said frequency | count of a fluctuation | variation, it transfers to the normal mode from the said special mode.

  As shown in FIG. 5A, a pattern group (“first pattern group” 501) to be selected in the special mode after the small hit game, which is an example of the low probability special mode, and the high probability special mode A pattern group (“second pattern group” 502) to be selected in the special mode after the latent probability variation game, which is an example, is composed of different pattern groups.

  Then, in the low probability special mode (special mode after the small hit game), the average value of the number of changes in each pattern of the pattern group (“first pattern group” 501) to be selected is the high probability special mode. In the case of the mode (special mode after 2R latent probability variation jackpot game), it becomes smaller than the average value of the number of fluctuations applied to each pattern of the pattern group (“second pattern group” 502) to be selected. Each pattern of the first pattern group 501 and the second pattern group 502 is set and stored in the table 303.

  That is, the average value of the number of fluctuations applied to each pattern of the first pattern group 501 is “17 times”, whereas the average value of the number of fluctuations applied to each pattern of the second pattern group 502 is “23 times”. It can be seen that the average value of the number of changes in each pattern of the first pattern group 501 is smaller than the average value of the number of changes in each pattern of the second pattern group 502. .

  In addition, among the patterns in the first pattern group 501, the number of patterns with the largest number of changes is smaller than the number of patterns with the same number of changes in each pattern in the second pattern group 502. Each pattern of the first pattern group 501 and the second pattern group 502 may be set and stored in the table 303.

  That is, in FIG. 5A, in the first pattern group 501, the maximum number of changes “30” is two patterns “I” and “J”, whereas the second pattern group 502 Then, the number of patterns having the same number of fluctuations (“30 times”) is three, “G”, “H”, and “I”, and the first pattern group 501 is more than the second pattern group 502. It can be seen that there are few.

  In addition, patterns whose number of fluctuations is greater than or equal to a predetermined number may be set only in the second pattern group 502 and stored in the table 303. In other words, in FIG. 5A, it can be seen that the number of fluctuations “50 times” is set only in the second pattern group 502 and is not set in the first pattern group 501.

  In this way, by setting the table 303, the player can feel the length of the special mode sensuously and can infer whether the current state is a high probability state or a low probability state. It becomes. For the player, the game based on the guess becomes one of the fun of the game when the mode is shifted to the special mode.

  Of course, when you win a small hit game in the low probability state, continue to win the 2R latent probability variation jackpot game when the low probability state continues, and then the high probability state continues There are also patterns with the same number of fluctuations (specifically, small hit game patterns “A” to “E” with a fluctuation number of “10 times” and 2R latent probability fluctuation big hit game patterns “A” to “ “C”, small hit game patterns “F” to “H” with a variation count of “20”, 2R latent probability variation big hit game patterns “D” to “F”, and the variation count is “30 times” Some small hit game patterns “I” and “J” and 2R latent probability variation jackpot game patterns “G” to “I”).

  Therefore, when these patterns are selected and set, the player wins the small hit game, and continues to win the 2R latent probability variation jackpot game when the low probability state continues, and then the high probability. When the state continues, the special mode effect and the transition timing to the normal mode are exactly the same, and thus cannot be clearly distinguished from each other.

  This makes it impossible for the player to guess which is very easy. In this way, the difficulty of guessing whether the state is a low probability state or a high probability state increases the enjoyment for players (especially those who are familiar with gaming machines called so-called advanced players) and gives a sense of excitement to the game. It will be.

  FIG. 5-2 is based on the data structure of FIG. 5-1, winning the small hit game in the low probability state, and subsequently winning the 2R latent probability variation jackpot game when the low probability state continues and Then, the comparison of the frequency | count of a fluctuation | variation of the symbol when the high probability state is continuing is shown.

  As can be seen from FIG. 5-2, in a pattern with a small number of fluctuations (for example, “10 fluctuations”), a small hit game is won in the low probability state, and the low probability state continues. There are fewer cases (5), and there are fewer cases (3) when the 2R latent probability variation jackpot game is won and then the high probability state continues. Accordingly, when the special mode is finished in a state where the number of fluctuations is relatively small, the player can estimate that the game is in a low probability state rather than in a latent probability variation game state (high probability state).

  Even if the exact number of changes is not counted, if the special mode duration is short and the special mode ends relatively quickly, it can be inferred that it is not a latent probability variation gaming state (high probability state) (of course, gaming Contrary to the player's expectation, even if the number of times of change is 10, it may be in the 2R latent probability changing game state (high probability state), which is a player's false guess).

  On the other hand, in a pattern with a large number of fluctuations (for example, “30 fluctuations”), the number of cases where a small hit game is won in the low probability state and the low probability state continues continues to be smaller (2). There are more cases where the 2R latent probability variation jackpot game is won and then the high probability state continues (three). Thereby, when the special mode is ended in a state where the number of changes is relatively large, the player can estimate that the game state is a 2R latent probability change game state (high probability state) rather than a low probability state. .

  Even if the exact number of changes is not counted, if the duration of the special mode is long and the special mode does not finish very easily, it can be assumed that it is a latent probability variation gaming state (high probability state) (of course, the player Contrary to this prediction, even if the number of fluctuations is 30, it may remain in a low probability state, in which case it is a player's false guess).

  In the case where the number of fluctuations is neither large nor small, but in an average case (for example, “20 fluctuations”), the player wins the small hit game in the low probability state and continues to the case where the low probability state continues and 2R It is the same number (3) in the case of winning the latent probability variation jackpot game, and then the high probability state continues, it is difficult to guess which is the average number of variations It will be.

  Further, as the number of times of variation increases, the number of patterns decreases when a small hit game is won in the low probability state and the low probability state continues. That is, even when a small hit game is won in the low probability state and the low probability state continues, “10 times: 5” → “20 times: 3” → “ “30 times: 2” → “50 times: 0”, the more the number of changes, the smaller the probability of winning a small hit game in the low probability state, and the lower the probability state continues. You can see that it decreases. Therefore, the player can win the 2R latent probability variation jackpot game as the number of times of change increases, and thereafter can increase the belief that the high probability state continues.

  On the other hand, when the 2R latent probability variation jackpot game is won and then the high probability state continues, the number of patterns does not increase or decrease as the number of changes increases. 10 times: 3 ”→“ 20 times: 3 ”→“ 30 times: 3 ”. This shows that there is a possibility that the 2R latent probability variation jackpot game will be won almost evenly at any number of changes, and that the high probability state will continue thereafter.

  However, the present invention is not limited to this, even if the 2R latent probability variation jackpot game is won and then the high probability state continues, the small hit game is won in the low probability state, and the low probability continues. As in the case where the state continues, the number of patterns may be reduced as the number of fluctuations increases, and conversely, the number of patterns may be increased as the number of fluctuations increases.

  Furthermore, among the patterns in the special mode, the variation number type (2R latent probability variation jackpot game pattern “J”) whose variation count is equal to or greater than a predetermined number (50 times) is set only in the case of the latent probability variation game jackpot game. Like that. For so-called advanced users, it can be known that the high probability state has been established by changing the special symbol more than the number of times (31 times) exceeding the number of changes of other special symbols. As a result, the advanced mode will continue for a long time in the special mode, and will feel a sense of superiority for the high probability state that has been established even though the special mode has continued, along with a sense of accomplishment of the expectation that has been held in the meantime. be able to.

  Furthermore, such a 2R latent probability variation jackpot game pattern “J” has a sense of achievement that the special symbol has been allocated by lowering the probability of being selected and making it rarer than the special symbol of the other variations. A sense of fulfillment can be given to the player.

  In addition, when the small hit game is won in the low probability state, and the low probability state continues, the average number of changes is 17 times, and the 2R latent probability change jackpot game is won, and then the high probability state is When it continues, the average number of fluctuations is 23. Accordingly, when all the patterns “A” to “J” are viewed as a whole, the 2R latent probability variation jackpot game is won, and after that, when the high probability state continues, the small hit game in the low probability state The average number of fluctuations is higher than when the low probability state continues to be won. Also from this fact, the more the number of turns in the special mode (the more it fluctuates), the higher the probability of a high probability state.

  Therefore, a player who knows that the probability of a high probability state improves as the variation of the special symbol continues, is said to be in a high probability state over time after entering the special mode. The degree of expectation can be increased, and the degree of concentration on the image display unit 104 can be increased. Therefore, even more advanced players can be provided with a timeless presentation during the game.

  In addition, as described above, in the special mode, a small hit game is won in the low probability state, and whether the low probability state continues, whether the 2R latent probability variation jackpot game is won, and then the high probability state is In order to guess whether it is continuing, it is necessary to change the special symbol more. In the special mode, in general, there is often no support by the electric tulip, and in order to change the special symbol more, it is necessary to fire more game balls. Therefore, it is possible to promote the launch of the game ball and assist in improving the state in which the game ball is being fired, that is, the operation rate of the so-called game table.

  Although not shown in the figure, exceptionally, the 2R latent probability variation jackpot game is won, and even if the high probability state continues, the small hit game is won in the low probability state. By preparing a pattern with a smaller number of fluctuations than when the low probability state continues, the player is said to be in a low probability state if the fluctuation number state is small, and a high probability state if the fluctuation number is large. There may be things that overturn the idea-based guess, confuse the player, and make the guess more difficult.

  Although not shown in the figure, if the 2R latent probability variation jackpot game is won and then a high probability state continues, a pattern type with an extremely small number of variations (for example, once or twice) is prepared. You may make it do. As a result, if the special mode ends in no time, the 2R latent probability variation jackpot game is won with a very high probability, and then the player is informed that the high probability state continues. It may be.

  The number of fluctuations is 10, 20, 30, and 50 for convenience of explanation, but is not limited to this, and should be set as appropriate based on the type of symbols and game effects. Can do.

(Details of jackpot determination process)
Next, processing contents of the jackpot determination process of the pachinko gaming machine 100 according to the present embodiment will be described. FIG. 6 is a flowchart showing the contents of the jackpot determination process. In the flowchart of FIG. 6, it is determined whether or not the game ball has won a start winning opening (first start opening 105, second start opening 106) (step S601). Specifically, the determination is made based on whether or not the first start port SW221 and the second start port SW222 are detected.

  In step S601, the main control board 201 waits for the game ball to win the start winning opening (step S601: Yes), and the main control board 201 uses a jackpot random number table (not shown) to determine the jackpot determination process ( A lottery is performed (step S602), and it is determined whether or not it is a big hit (for example, a win with a probability of 1/300 (low probability state)) (step S603). Specifically, the determination is made based on whether or not a random number value from 0 to 299 has resulted in a predetermined random value (for example, “3”).

  Here, when it is not a big hit (step S603: No), it is then determined whether or not it is a big hit (step S604). Specifically, using the jackpot random number table, determination is made based on whether or not a predetermined random number value (for example, “150”, “200”, “250”) among the random number values from 0 to 299 is obtained. . If it is a small hit (step S604: Yes), a small hit process (see FIG. 7 described later) described below is performed. On the other hand, if it is not a small hit in step S604 (step S604: No), it is out of order, so the process returns to step S601, and thereafter, steps S601 to S604 are repeated.

  If the jackpot is a big hit in step S603 (step S603: Yes), it is next determined whether the jackpot is a 2R (round) jackpot or a 15R (round) jackpot (step S605). Here, if it is not 2R jackpot, that is, if it is 15R jackpot (step S605: No), then 15R jackpot processing (description is omitted) is executed.

  If it is 2R big hit in step S605 (step S605: Yes), it is next determined whether or not there is a variation in latent probability (step S606). Here, when it is not a latent probability variation (step S606: No), a sudden probability variation process (not described) is executed. On the other hand, when it is a latent probability variation (step S606: Yes), a latent probability variation process (see FIG. 8) described later is executed. Note that all the steps S603 to S606 may be determined simultaneously.

(Content of small hit processing)
Next, processing contents of the small hit processing will be described. FIG. 7 is a flowchart showing the processing contents of the small hit processing. In the flowchart of FIG. 7, the special winning opening is opened twice for 0.1 seconds, for example, and a symbol setting process for small hitting is performed (step S701).

  Thereafter, the mode change unit 305 changes the mode so as to shift to the special mode (step S702). At this time, the number of symbol fluctuations is set with reference to the table 303. And the production | presentation control part 202 fluctuates the symbol set in step S701, and displays it (step S703). Next, the variation count counting / determination unit 304 counts the variation count (winning count) after the mode change, and the counted variation (winning count) count is set to n times (n times are set with reference to the table 303). It is determined whether or not the number of symbols has changed (indicating the number of times of variation of the symbol) (the number of times of variation> n) (step S704).

  Here, when it is not yet more than n times (the number of fluctuations ≦ n times) (step S704: No), it is next determined whether or not there is a new winning at the start winning opening (step S705). Then, after waiting for a new winning, if there is a new winning (step S705: Yes), the main control board 201 performs a jackpot determination process as in step S602 of FIG. 6 (step S706). ). Here, similarly, it is determined whether or not it is a big hit (for example, it has been hit with a probability of 1/300 (low probability state)) (step S707). In step S707, if it is a big hit (step S707: Yes), the process moves to step S605 in FIG.

  On the other hand, if it is not a big hit in step S707 (step S707: No), it is next determined whether or not it is a big hit (step S708). If it is a small win (step S708: Yes), the process returns to step S701, and after a special winning opening is opened twice for 0.1 seconds, for example, a small hit process is performed.

  If it is not a small hit in step S708 (step S708: No), it is out of order, so the variation count counting / determination unit 304 increments the variation count counter by 1 (step S709), and then returns to step S703. Steps S703 to S709 are repeated. As described above, when neither big win nor small win is obtained, the variation counter is incremented by 1 and the same processing is repeated.

  In step S704, the variation count / determination unit 304 counts the number of variations after the mode change (winnings count), and the counted variation count is greater than n (variation count> n times). If the number of changes is greater than n (number of changes> n) (step S704: Yes), the mode change unit 305 switches from the current special mode to the normal mode. The mode is changed (step S710). Thereafter, the process proceeds to step S601 shown in FIG.

(Contents of latent probability variation processing)
Next, processing contents of the latent probability variation processing will be described. FIG. 8 is a flowchart showing the processing contents of the latent probability variation jackpot processing. In the flowchart of FIG. 8, similarly to the small hit process shown in FIG. 7, the probability variation processing unit 308 performs the probability variation process after the big prize opening is opened twice for 0.1 seconds (that is, 2R), for example. This is performed (step S801).

  Specifically, the probability variation process is executed by turning on a latent probability variation game flag. As a result, the probability of the subsequent jackpot changes, and the symbol setting process in the latent probability change is performed (step S802). Thereafter, the mode change unit 305 changes the mode so as to shift to the special mode (step S803). At this time, the number of symbol fluctuations is set with reference to the table 303.

  Thereafter, steps S804 to S810 are the same as steps S703 to S709 of the small hit processing shown in FIG. However, since the jackpot determination process in step S807 is in a high probability state, as a result of lottery by the main control board 201 using a jackpot random number table (not shown), specifically, random number values from 0 to 299 are obtained. Among them, predetermined random numbers (for example, “3”, “7”, “37”, “67”, “97”, “127”, “157”, “187”, “217”, “247”) Judgment is made based on whether or not any of the above values is reached. Thus, the probability of being a big hit in the high probability state is a high probability state of 10/300, which is 10 times that of the low probability state. This is the difference from the small hit state.

  In step S805, the variation count counting / determination unit 304 counts the variation count (winning count) after the mode change, and the counted variation count is set n times (n times are set with reference to the table 303). If the number of changes is greater than n (number of changes> n), the number of changes is greater than n (the number of changes is greater than n). In step S805: Yes), the mode is changed from the current special mode to the normal mode (step S811).

  Next, it is determined whether or not there is a new winning at the start winning opening (step S812). Then, when there is a new winning after waiting for a new winning (step S812: Yes), the main control board 201 performs a jackpot determination process in a high probability state as in step S807 (step S807). S813). Here, similarly to step S807, it is determined whether or not the game is a big hit (for example, a win with a probability of 10/300 (high probability state)) (step S814). In step S814, when it is a big hit (step S814: Yes), it moves to step S605 of FIG.

  On the other hand, if it is not a big hit in step S814 (step S814: No), it is next determined whether or not it is a big hit (step S815). If it is a small win (step S815: Yes), the process returns to step S701 shown in FIG. 7 to perform a small hit process after the special winning opening is opened twice for 0.1 seconds, for example.

  In step S815, if it is not a small hit (step S815: No), it is out of order, so the process returns to step S812, and thereafter, steps S812 to S815 are repeated. Thus, even in the normal mode, since the high probability state continues, the probability of being a big hit remains 10/300 (high probability state).

  In this way, the small hit processing when winning a small hit game in a low probability state and the latent probability variation processing when winning a latent probability variation jackpot game are almost the same except that the winning ratio of the jackpot is different. It becomes processing. Therefore, it is difficult for a player to distinguish between the two. Therefore, it is the most effective method to let the player guess which state is based on the difference in the number of fluctuations of the special symbol.

  As described above, the pachinko gaming machine 100 according to the present embodiment is referred to as the low probability special mode) and the high probability special mode when controlling the production contents so as to be the same mode. In the high probability special mode, one of the patterns is selected from a table storing a pattern group composed of a plurality of patterns having different numbers of symbol variations, and the variation of the symbol is varied according to the selected pattern. The first pattern group 501 to be selected in the case of the low probability special mode, and the high probability special mode. In this case, since the second pattern group 502 to be selected is composed of different pattern groups, from the difference in the number of changes, the player I can guess degree to which a rate change gaming state, it is possible to improve the elation in special mode.

  Further, in the pachinko gaming machine 100 according to the present embodiment, the number of patterns having the smallest number of changes in each pattern of the second pattern group 502 is changed, and the number of changes in each pattern in the first pattern group 501 is set. Each pattern of the first pattern group 501 and the second pattern group 502 is set and stored in the table 303 so as to be smaller than the number of the same patterns.

  Further, in the pachinko gaming machine 100 according to the present embodiment, among the patterns of the first pattern group 501, the number of patterns with the largest number of changes is the number of changes among the patterns of the second pattern group 502. Each pattern of the first pattern group 501 and the second pattern group 502 is set and stored in the table 303 so as to be smaller than the number of the same patterns.

  In addition, the pachinko gaming machine 100 according to the present embodiment is characterized in that patterns whose number of fluctuations is greater than or equal to a predetermined number are set only in the second pattern group 502 and stored in the table 303.

  With these settings, the number of changes in the design is set to be greater in the case of the latent probability variation game state, the more the number of changes, in other words, the longer the state of the special mode continues, It is possible to inform the player that there is a high possibility that the game state is in the probability variation game state.

  Furthermore, among the symbols in the special mode, if the symbol with the number of fluctuations greater than or equal to the predetermined number is set only in the latent probability variation gaming state, a player who knows the specifications of the gaming machine equipped with the function. Therefore, it is possible to know that the probability variation gaming state is confirmed by the symbol changing more than the predetermined number of times, and to make the player feel a sense of superiority as well as a sense of accomplishment.

  Thus, even in the function of latent probability variation jackpot game, it is possible to improve the fun without getting bored of the player regardless of whether it is a beginner or an advanced player. Further, the operating rate of the gaming machine can be increased accordingly.

  In the above embodiment, a small hit game is shown as an example of an event in which the state after the event is in a low probability state, and a 2R latent probability variation big hit game is shown in an event in which the state after the event is in a high probability state. However, the present invention is not limited to this. In other words, in at least one of the symbol variation patterns set in the special mode, when transitioning after winning an event in which the state after the event becomes a low probability state, the state after the event is a high probability state. It may be set so that the number of symbol fluctuations is different in the case where the event is transferred after winning the event.

  As an event in which the state after the event becomes a high probability state, for example, an event such as “sudden probability change big hit game” may be included. Further, as an event in which the state after the event becomes a low probability state, for example, an event such as “sudden time reduction game” or “sudden normal jackpot game” may be included.

  The presentation control method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a medium that can be distributed via a network such as the Internet.
