BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of ball game machines.
[0002]
[Prior art]
Normal symbol lottery means for performing normal symbol lottery due to a game ball entering the normal symbol lottery area (for example, a passage entrance), normal symbol display means for displaying the result of the normal symbol lottery as a normal symbol, and normal symbols Normal symbol control means for controlling the display means to display a fixed symbol after variably displaying it, and a variable winning device that makes it easy to win in an open state when the normal symbol lottery is won (for example, a tulip-type winning device) The special symbol starting device (ordinary electric accessory) which is a starting device control means for releasing the normal symbol after being displayed, and the special symbol lottery means for performing the special symbol lottery due to the winning of the special symbol starting device And a special symbol display means for displaying the result of the special symbol lottery as a special symbol, and a special game for executing a special game advantageous to the player on the condition that the special symbol lottery is a win. There are pinball game machine comprising an execution unit.
[0003]
In this type of ball game machine, the probability of winning in a normal symbol lottery is increased in the case of so-called probability change or short time (hereinafter collectively referred to as "special state"), and the opening time of the special symbol starter is reduced. May be longer. Also, when the special state and not (hereinafter referred to as “normal state”), the change time of the normal symbol is changed (the special state is shorter), but during the special state, the change time is constant, The same was true in the normal state.
[0004]
[Problems to be solved by the invention]
Since the special symbol starter is released in synchronization with the normal symbol confirmation display (that is, the end of the fluctuation), the player can predict when the special symbol starter will be released, and the game ball will match the timing. It was easy to make a so-called “stop” that fired or stopped firing.
[0005]
Stopping is a means for efficiently obtaining a prize ball for the player, but for a game shop, the operation rate of the ball game machine has deteriorated and the rate of appearance has increased.
[0006]
[Means for Solving the Problems and Effects of the Invention]
  A ball game machine according to claim 1 for solving the above-mentioned problem,
A normal symbol lottery means for performing a normal symbol lottery due to a game ball entering the normal symbol lottery area; a normal symbol display means for displaying the result of the normal symbol lottery in a normal symbol; and the normal symbol display means. A normal symbol control means for controlling and displaying a normal symbol after being controlled and a special symbol starting device which is a variable winning device that makes it easy to win in an open state when the normal symbol lottery is won. A starter control means for releasing the symbol after the symbol is displayed, a special symbol lottery means for performing a special symbol lottery due to winning in the special symbol starter, and a result of the special symbol lottery display as a special symbol In a ball game machine comprising special symbol display means and special game execution means for executing a special game advantageous to a player on the condition that the special symbol lottery was a win,
  Time determining means for determining the elapsed time from the detection of the entry of the game ball to the normal symbol lottery area until the opening of the special symbol starting device is determined indefinitely each time.,
  The time determination means selects the elapsed time based on whether or not there is a memory (special symbol hold memory) relating to the special symbol lottery that cannot immediately start the display operation of the lottery result.
  By doing this,The elapsed time from when the game ball enters the normal symbol lottery area (for example, the passage opening) until the special symbol starter (normal electric accessory) is released is not constant, and the special symbol starter is open to the player. Cannot predict the timing.
[0007]
As a result, not only is it not easy to fire a game ball or stop firing in accordance with the timing of the special symbol starter, but it is also not possible to obtain the effect of efficiently winning a winning ball. That is, since there is no merit of stopping, there is no player who performs this, the deterioration of the operation rate of the ball game machine is prevented, and the pitch rate does not rise specially.
[0008]
  When making the elapsed time from the detection of the entry of a game ball into the normal symbol lottery area until the release of the special symbol starter each time non-constant, the player is clearly related to the release of the special symbol starter Since it is possible to recognize the fluctuation of the normal symbol, it is only necessary to make the fluctuation time, particularly the timing of determining the normal symbol, indefinite.
  Also, the fact that the lottery result display operation cannot be started immediately means that, for example, a special symbol is being displayed in a variable manner in order to display the preceding lottery result, and the display operation cannot be started without waiting for the confirmation. This is a case where the display operation cannot be performed in relation to the state (for example, during execution of a special game). The memory related to the special symbol lottery refers to a random value or a lottery result used for the special symbol lottery. Normally, there is an upper limit to the number of special symbol reservation memories (usually up to four).
  Since the special symbol hold memory increases by winning the special symbol starting device, if the special symbol hold memory is further increased when there is a special symbol hold memory, the special symbol hold memory may overflow. Therefore, when there is a special symbol hold memory, it is better not to increase it as much as possible, that is, not to open the special symbol starter.
  On the other hand, in the case of the ball game machine according to claim 1, when there is a special symbol holding memory, the special symbol starting device is delayed by delaying the opening of the special symbol starting device by prolonging the fluctuation of the normal symbol being executed or will be executed in the future. The increase in symbol hold memory can be suppressed, and when there is no symbol hold memory, the fluctuation of the normal symbol that is being executed or will be executed in the future will be shortened to increase the release frequency per hour of the special symbol starter, Can be given a special symbol lottery.
  In addition, by selecting the elapsed time according to the number of special symbol hold memories, it is possible to select the variation time of the normal symbol more finely.
[0009]
  In order to make the timing of determining the normal symbol indefinite, the starting point may be the normal symbol change start time, or may be when the entry of a game ball into the normal symbol lottery area is detected.
  Further, in the bullet ball game machine according to claim 2, the time determination means sets the determination range of the elapsed time based on the presence / absence or number of the special symbol hold memory, and the game to the normal symbol lottery area A time within the determination range is selected as the elapsed time based on a random number extracted due to the detection of the entry of a sphere. By doing so, the elapsed time can be determined randomly with a relatively simple configuration.
[0010]
  According to a third aspect of the present invention, the ball game machine according to claim 3 is provided with a normal mode in which the probability of winning by the normal symbol lottery means is relatively low or the fluctuation time of the normal symbol is relatively long, and the normal symbol lottery means. There is a special mode in which the probability of winning is relatively high or the variation time of the normal symbol is relatively short, and the time determining means operates in the special mode.
  The normal symbol lottery means using the low probability lottery with a relatively low probability of winning and the high probability lottery with a higher probability of winning than the low probability lottery are also used in conventional ball game machines. ing. Normally, when the probability variation (probability variation) in which the chance of winning in the special symbol lottery is higher than normal or when the special symbol variation time is shortened after the special game is finished, the normal symbol lottery has a high probability. It will be a lottery.
[0011]
The opening time of the special symbol starting device is short during the period when the low-probability lottery is performed (for example, about 0.2 to 0.3 seconds), and is 2-3 seconds during the period when the high-probability lottery is performed. It has been long to the extent. However, since there is also an upper limit for the number of winnings, it may return to the closed state before this time is reached.
[0012]
  Therefore, if the opening time of the special symbol starting device is such a setting, it is impossible to launch a game ball aiming at the opening timing of the special symbol starting device during the period when the low probability lottery is performed. However, it can be performed sufficiently during the period when the high probability lottery is performed. Therefore, it is sufficient to make the timing at which the special symbol starting device is opened only during the period when the high probability lottery is performed. That is, the claim3The object of the invention can be sufficiently achieved with the configuration of. Moreover, there is an advantage that the processing amount of the CPU can be reduced by limiting the operation period of the time determining means in this way.
[0014]
  further,In normal ball game machines, the probability of winning in the special symbol lottery is usually higher when the probability variation (probability variation) is higher than normal, or when the special symbol variation time is shortened after the special game ends Usually, the symbol variation time is shorter (normal mode, variation time is about 28 to 29 seconds) (time reduction mode).
[0015]
The opening time of the special symbol starting device is short in the normal mode (for example, about 0.2 to 0.3 seconds), and is long in the time reduction mode, for example, about 2 to 3 seconds. However, since there is also an upper limit for the number of winnings, it may return to the closed state before this time is reached.
[0016]
  Therefore, if the opening time of the special symbol starter is set in this way, it is impossible to launch a game ball aiming at the opening timing of the special symbol starter in the normal mode. Can do enough. Therefore, only the short time mode is sufficient to make the timing at which the special symbol starting device is opened indefinite. In other words, the object of the invention can be sufficiently achieved with the structure of claim 3. Moreover, there is an advantage that the processing amount of the CPU can be reduced by limiting the operation period of the time determining means in this way..
[0027]

The sound control board 98 controls sound output from the speakers.
[0039]
Next, the operation of the pachinko machine 10 is mainly focused on the processing of the main control board 70 (particularly the CPU 70a) and the processing of the display control board 90 (particularly the CPU 90a), which are mainly related to the display of the normal symbol display 27 and the liquid crystal display device 26. Will be explained. Note that each processing of the CPU 70a described below is executed as a subroutine of a main routine (illustration and description omitted).
[0040]
FIG. 4 shows a lottery random number reading process for special symbols and ordinary symbols. In this process, the CPU 70a determines whether or not a game ball detection signal (special symbol start signal) from the winning sensor 31a of the variable winning device 31 is input, that is, whether or not the gaming ball has won the variable winning device 31. Judgment is made (S51).
[0041]
If the determination is affirmative, the value of the counter 70d is read (S52), and whether or not four special symbol lottery random numbers are stored in the special symbol lottery random number storage area provided in the RAM 70c, that is, the special symbol hold is four. It is determined whether or not the number has been reached (S53). If there are three or fewer holds (S53: NO), the value read in S52 is stored as a special symbol lottery random number in the special symbol lottery random number storage area (S54).
[0042]
When a negative determination is made at S51, when an affirmative determination is made at S53, or after S54, the CPU 70a determines whether or not a passing ball detection signal (ordinary symbol start signal) is input from the gate 34, that is, the game ball moves through the gate 34. It is determined whether or not it has passed (S55).
[0043]
If the determination is affirmative, the value of the counter 70e is read (S56), and whether or not four normal symbol lottery random numbers are stored in the normal symbol lottery random number storage area provided in the RAM 70c, that is, the normal symbol hold is four. It is determined whether or not the number has been reached (S57). If there are three or less holds (S57: NO), the value read in S56 is stored in the normal symbol lottery random number storage area as a normal symbol lottery random number (S58).
[0044]
When a negative determination is made at S55, an affirmative determination is made at S57, or after S58, the process returns.
Next, the normal symbol lottery will be described with reference to FIG.
In this process, the CPU 70a first determines whether or not the normal symbol display 27 is displaying a variable (S100). If the determination is affirmative, the process returns from this process without performing a substantial process.
[0045]
When a negative determination, that is, when the normal symbol is not changing, it is determined whether or not the normal symbol lottery random number is stored in the normal symbol lottery random number storage area (S101). If the determination is negative, the process returns.
If there is an affirmative determination, that is, if there is the normal symbol lottery random number stored in S58, the oldest one is read and deleted from the normal symbol lottery random number storage area (S102). In addition, since the CPU 70a holds the normal symbol lottery random number in a register, for example, the lottery random number itself does not disappear.
[0046]
Next, the CPU 70a determines whether or not the high-probability lottery mode is set (S103). In the case of the present embodiment, when the special symbol lottery is performed with a high probability (during so-called probability change), the high-probability lottery mode is performed. In this mode, the normal symbol lottery is also performed with a high probability. Needless to say, the probability of the special symbol lottery and the probability of the normal symbol lottery are not the same. In this embodiment, in the normal probability lottery mode, the winning probability of the special symbol lottery is about 1/300, and the winning probability of the normal symbol lottery is 1/10. In the high probability lottery mode, the winning probability of the special symbol lottery is about 1/300. 60, the probability of winning the normal symbol lottery is 9/10.
[0047]
If it is the high probability lottery mode (S103: YES), a time determination routine (S104) for determining the fluctuation time of the normal symbol is executed. Since there are various variations in this process, some typical examples will be described with reference to FIGS. The CPU 70a corresponds to time determination means by executing time determination routines 1 to 5.
[Time determination routine 1]
This example is an example of determining according to the number of reserved normal symbols (the number of normal symbol lottery random numbers stored in the normal symbol lottery random number storage area).
[0048]
As shown in FIG. 8, in this example, it is first determined whether or not the number of normal symbols held is other than 0 (any one of 1 to 3) (S120). In S102, since the normal symbol lottery random numbers to be selected for the current lottery are deleted from the normal symbol lottery random number storage area, the number of the normal symbol lottery random numbers other than the target for the current lottery is determined.
[0049]
If negative determination is made in S120, that is, if the number of normal symbols held is 0, a change time of 7 seconds is selected (S121). If the determination is affirmative, whether or not the number of normal symbols held is other than 1 (2 or 3). Judgment is made (S122).
In S122, a negative determination is made, that is, if the number of held ordinary symbols is 1, a variation time of 6 seconds is selected (S123). If an affirmative determination is made, it is determined whether the number of retained ordinary symbols is other than 2 (ie 3). (S124).
[0050]
If a negative determination is made in S124, that is, if the number of normal symbols held is 2, then a change time of 5 seconds is selected (S125), and if a positive determination is made, a change time of 4 seconds is selected (S126).
[Time determination routine 2]
This example is an example of determining according to the number of reserved special symbols (the number of special symbol lottery random numbers stored in the special symbol lottery random number storage area).
[0051]
As shown in FIG. 9, in this example, it is first determined whether or not the number of reserved special symbols is other than 0 (any one of 1 to 4) (S130).
If the negative determination in S130, that is, if the number of reserved special symbols is 0, a variation time of 4 seconds is selected (S131). If the determination is affirmative, whether the number of reserved special symbols is other than 1 (any of 2 to 4). It is determined whether or not (S132).
[0052]
If negative determination is made in S132, that is, if the number of reserved special symbols is 1, 5 seconds is selected (S133). If the determination is affirmative, whether the number of reserved special symbols is other than 2 (that is, 3 or 4). Judgment is made (S134).
In S134, a negative determination is made, that is, if the number of reserved special symbols is 2, a 6-second fluctuation time is selected (S135). If an affirmative determination is made, it is determined whether the number of reserved special symbols is other than 3 (that is, 4). (S136).
[0053]
In S136, a negative determination is made, that is, if the number of special symbols to be held is 3, a change time of 7 seconds is selected (S137), and if a positive determination is made, a change time of 8 seconds is selected (S138).
[Time determination routine 3]
This example is an example of determination based on a random value.
[0054]
As shown in FIG. 10, in this routine, the value of the counter 70f for time determination is read (S140), and the range of 3 to 8 seconds corresponding to the value (for example, according to the random number value and variation time comparison table). The variation time is selected with (S141).
[Time determination routine 4]
In this example, the number is determined according to the random number value and the number of reserved ordinary symbols.
[0055]
As shown in FIG. 11, in this routine, first, the value of the time determination counter 70f is read (S150).
Next, it is determined whether or not the reserved number of normal symbols is other than 0 (any one of 1 to 3) (S151).
[0056]
If a negative determination is made in S150, that is, if the number of held ordinary symbols is 0, a variation time is selected in the range of 6 to 7 seconds corresponding to the value of the counter 70f (S152). It is determined whether it is other than 1 (2 or 3) (S153).
[0057]
If a negative determination is made in S153, that is, if the number of held ordinary symbols is 1, a fluctuation time of 5 to 6 seconds is selected corresponding to the value of the counter 70f (S154). That is, it is determined whether or not 3) (S155).
If a negative determination is made in S155, that is, if the number of ordinary symbols held is 2, a variation time of 4 to 5 seconds is selected corresponding to the value of the counter 70f (S156), and if an affirmative determination is made, 3 corresponding to the value of the counter 70f is selected. A variation time of ˜4 seconds is selected (S157).
[Time determination routine 5]
This example is an example of determining according to a random number value and the number of reserved special symbols.
[0058]
As shown in FIG. 12, in this routine, the value of the time determination counter 70f is first read (S160).
Next, it is determined whether the number of reserved special symbols is other than 0 (any one of 1 to 4) (S161).
[0059]
If the negative determination in S130, that is, if the number of reserved special symbols is 0, the variation time is selected in the range of 3 to 4 seconds corresponding to the value of the counter 70f (S162). It is determined whether it is other than 1 (any one of 2 to 4) (S163).
[0060]
If a negative determination is made in S163, that is, if the number of reserved special symbols is 1, a variation time of 4 to 5 seconds is selected corresponding to the value of the counter 70f (S164). If the determination is affirmative, the number of reserved special symbols is other than 2 ( That is, it is determined whether or not 3 or 4) (S165).
[0061]
If the negative determination is made in S165, that is, if the number of reserved special symbols is 2, a variation time of 5 to 6 seconds is selected corresponding to the value of the counter 70f (S166). That is, it is determined whether or not 4) (S167).
If negative determination is made in S167, that is, if the number of reserved special symbols is 3, a change time of 6 to 7 seconds is selected corresponding to the value of the counter 70f (S168), and if positive determination, the value corresponding to the value of the counter 70f is selected. A variation time of 7 to 8 seconds is selected (S169).
[0062]
As shown in FIG. 5, after the normal symbol variation time is determined by any one of these time determination routines 1 to 5 or any other appropriate method (S104), the normal symbol lottery random number read in S102 is high. A lottery is performed in the probability lottery mode (S105). When a negative determination is made in S103, the normal symbol change time is set to a default value (about 28 seconds in this embodiment) (S106), and lottery is performed in the normal probability lottery mode (S107). In this embodiment, the counter 70e is configured to repeatedly count integer values from 0 to 9 in ascending order. In the normal probability lottery mode, 0 is a winning value, and in the high probability lottery mode, a non-zero is a winning value. If the lottery random number matches one of the winning values, it is a win.
[0063]
If the lottery is a win (S108: YES), a normal symbol hit command for displaying the win is generated and transmitted to the display control board 90 (S109). This command includes variation time data that specifies the variation time determined in S104 or a default value.
[0064]
When the display control board 90 receives this command, the normal symbol display unit 27 displays the normal symbol in a variably manner, and the normal symbol is confirmed and displayed after the time specified by the variation time data.
The CPU 70a waits for the normal symbol to be determined, and controls the variable winning device 31 to open and close (S110). The opening time of the variable winning device 31 is about 0.3 seconds in the normal probability lottery mode and about 2.3 seconds in the high probability lottery mode.
[0065]
On the other hand, if the lottery is out (S108: NO), a normal symbol out command for displaying the out is generated and transmitted to the display control board 90 (S111). This command also includes variable time data. When the display control board 90 receives this command, the normal symbol display 27 displays the normal symbol in a variable manner, and the normal symbol is released after the time specified by the variable time data. Is displayed.
[0066]
For example, when the special symbol lottery is performed with a high probability (when the probability changes) or when the special symbol variation time is set shorter than usual (when the time is short), the probability of the normal symbol lottery is not changed to a high probability. In some cases, only the opening time of the variable winning device 31 is lengthened. In that case, what is necessary is just to change a part of process of FIG. 5 so that it may illustrate in FIG.
[0067]
In this example, S100 to S102 are the same as in FIG. 5, but subsequently whether or not the special symbol variation time is set shorter than usual is a short time state (in this example, the special symbol lottery in the short time state) Is determined with a high probability) (S103 ′), and if a positive determination is made, a time determination routine (S104) for determining the fluctuation time of the normal symbol is executed. The processing of this time determination routine is the same as in FIGS. When a negative determination is made in S103 ', the normal symbol change time is set to a default value (for example, about 28 seconds) (S106). Then, after S104 or S106, a lottery is performed for the normal symbol lottery random number read in S102 (S107 '). The subsequent processing is the same as in FIG.

Next, the special symbol lottery will be described with reference to FIG.
In this process, the CPU 70a first determines whether or not the special symbol variation display can be executed (S200). Specifically, it is determined whether the liquid crystal display device 26 is performing variable display or a special game is being executed. If a negative determination is made, the process returns from this process without performing a substantial process.
[0069]
If an affirmative determination, that is, if the special symbol can be displayed in a variable manner, it is determined whether or not a special symbol lottery random number is stored in the special symbol lottery random number storage area (S201). If the determination is negative, the process returns.
If there is an affirmative determination, that is, if there is the special symbol lottery random number stored in S54, the oldest one is read and deleted from the special symbol lottery random number storage area (S201). Note that since the special symbol lottery random number is held in the register by the CPU 70a, for example, the lottery random number itself does not disappear.
[0070]
Next, the CPU 70a determines whether or not the high-probability lottery mode is set (S203).
If it is the high probability lottery mode (S203: YES), the lottery in the high probability lottery mode is performed for the special symbol lottery random number that has been read (S204). Further, when a negative determination is made in S203, a low probability lottery is performed in the normal probability lottery mode (S205).
[0071]
If the lottery is a win (S206: YES), a win flag F is set (S207), a special symbol hit command for displaying a win is generated and transmitted to the display control board 90 (S208).
When receiving this command, the display control board 90 controls the liquid crystal display device 26 to display the special symbols in a variably manner, and then to confirm and display the corresponding special symbols.
[0072]
If the lottery is out (S206: NO), a special symbol out command for displaying the out is generated and transmitted to the display control board 90 (S209). Upon receiving this command, the display control board 90 displays the special symbol on the liquid crystal display device 26 in a variable manner, and then confirms and displays the special symbol that has come off.
[0073]
Here, when the winning special symbol is confirmed and displayed, a special game is started subsequently.
The special game itself executed in this embodiment is the same as a known pachinko machine of the type called the first type, but will be briefly described with reference to FIG. The CPU 70a functions as special game execution means in cooperation with the big prize device 36 by executing the special game process shown in FIG.
[0074]
In the special game process, the main control board 70 determines whether or not the hit flag F is set to 1 (S301). If the determination is negative, no substantial process is performed (the special game is not executed).
If an affirmative determination is made in S301, a jackpot opening command is sent to the display control board 90 to display the jackpot fanfare screen, then the big prize opening 40 is opened and closed, and the display control board 90 is set to a large number by a round number display command. Display of the number of times the winning opening 40 is opened (number of rounds), display of a jackpot screen by a jackpot symbol display command, display of the number of winnings (so-called count number) to the big winning opening 40 by a winning number command, specification by a specific area passing display command Various processes related to the special game are performed, such as instructing display of an area screen and display of an interval screen by an interval command (S302). Then, for example, if the specified number of rounds is executed and the special game is ended (S303: YES), display of the jackpot end screen is instructed by the jackpot ending command, and the hit flag F is reset (S304).
[0075]
Then, it is determined whether or not the high probability mode is set (probability variation) (S305). If the determination is affirmative, the probability variation flag is set (S306). If the determination is negative, the probability variation flag is cleared (S307). Here, when the probability variation flag is set, the high probability mode is set thereafter, and the special symbol lottery of FIG. 6 is performed with high probability. The determination as to whether or not to enter the high probability mode is based on the result of the probability variation lottery executed when the jackpot lottery is a win (S206: YES). That is, if the probability variation lottery is a win, the determination is affirmative in S305.
[0076]
In this embodiment, such a special game is played when a special symbol lottery is won, but the form of the special game executed on condition that the lottery is won is not limited to this.
As described above, this pachinko machine 10 is variable in the high-probability lottery mode from the time when it is detected that it has passed through the gate 34 by determining the variation time of the normal symbol in each display operation indefinitely. Since the elapsed time until the winning device 31 is released is not constant every time, the player cannot predict when the variable winning device 31 is opened.
[0077]
As a result, not only is it easy to fire a game ball or stop firing in accordance with the opening timing of the variable prize winning device 31, but the effect of stopping the ball to efficiently acquire a prize ball cannot be obtained. That is, since there is no merit of stopping, there is no player who performs this, the deterioration of the operation rate of the pachinko machine 10 is prevented, and the ball-out rate does not rise specially.
[0078]
In the normal probability lottery mode, since the opening time of the variable winning device 31 is short, it is impossible to fire a game ball aiming at the opening timing of the variable winning device 31 during that period. It is sufficient to make the release timing non-constant only during the high probability lottery mode. By limiting the execution period of the time determination routine to the high probability lottery mode, the processing amount of the CPU 70a can be reduced.
[0079]
The change time of the normal symbol is determined based on random numbers (time determination routine 3), and the elapsed time can be determined randomly with a relatively simple configuration.
The normal symbol hold memory overflow is prevented by making the determination range of the normal symbol change different depending on the presence or absence of the normal symbol hold memory (time determination routines 1 and 4), and by shortening the change time as the number of normal symbol hold memories increases. Thus, it is possible to make a profit for the player, and when there is no ordinary symbol holding memory or a small number of them, it is possible to make it seem that the variation of the ordinary symbol is frequent by prolonging the variation of the ordinary symbol.
[0080]
Also, the variation range of the normal symbol change time is made different depending on the number of special symbol hold memories (time determination routines 2 and 5), and when the number of special symbol hold memories is large, it can be varied by prolonging the fluctuation of the normal symbols. Delaying the opening of the winning device 31 can suppress an increase in the special symbol holding memory, and when there is no special symbol holding memory, by reducing the fluctuation of the normal symbol in a short time, the opening frequency per hour of the variable winning device 31 can be reduced. Increase the number of special symbol lottery opportunities for players.
[0081]
As mentioned above, although embodiment of this invention was described according to the Example, this invention is not limited to such an Example, and it cannot be overemphasized that it can implement variously in the range which does not deviate from the summary of this invention.
