When the fluctuation time of the special figure 1 big hit fluctuation has elapsed (see FIG. 165 (b)), the high likelihood state of the particular symbol shifts to the low likelihood state. In addition, when the primary particular symbol and the second special symbol are altering at the identical time, if one in every of them stops changing with a big hit or small hit stop symbol, the other change show exhibits the remaining change time or lottery Whatever the result, it’s stopped and displayed with an outlier stop image. In the present embodiment, since it is configured to win a small hit with a chance of about 1/2 in the lottery of the second special symbol, during the period when the latent state is set because the gaming state, When the participant wins, the small hit recreation is regularly executed, and a gaming state advantageous to a player who can acquire quite a lot of prize balls (a special determine 2 advantageous state) is obtained. Thus, since a plurality of states (special figure 2 advantageous state, jackpot gaming state) which can be advantageous to the participant are set in succession, numerous advantages are continuously given to the participant.

As described above, the period during which the latent state is about in the present embodiment (special determine 2 fluctuation advantageous interval) is in the course of the fluctuation show period (dynamic show interval) of the first particular symbol that is received in the jackpot in the probability variation state. Furthermore, in the primary embodiment, the variable display based on the lottery of the primary particular image and the variable display based on the lottery of the second special image will be executed concurrently (in parallel) (so-called simultaneous). For instance, regardless of whether or not the symbol is the primary special symbol or the second particular symbol, in the state the place one variation show is being executed, another variation display is probably not executed. By configuring in this way, it is possible to stop the special determine 2 variable advantageous period from being subtracted in the course of the small hit recreation, and subsequently, whatever the variety of small hit video games executed in the course of the special determine 2 variable advantageous interval. As a result, even when the variation show of one particular image is being executed, the variation display of the other particular symbol can be performed without ready for the end of the variation show, in order that the particular image lottery might be executed more effectively.

A certain special figure 2 variable advantageous interval might be provided to the participant. As described above, in the present embodiment, the management content material for the variation of the other special symbol is diversified in accordance with the lottery result of the one particular image. The excessive chance state of the traditional symbol shifts to the low probability state, and the gaming state shifts from the probability change state to the latent likelihood state. The predetermined number of fluctuations (for example, 10) after the state is set is configured such that a excessive probability state of the falling lottery that is easy to win the falling lottery is ready, after which a low likelihood state of the falling lottery is ready. Within the high likelihood variation state, a low likelihood state of the falling lottery is set, and the low likelihood variation is set. Therefore, it is possible to supply a novel gameability that allows the participant to expect the latent state to be set. Therefore, after the back picture change flag 233w is about to off (S7710), it is supplied for each again picture kind.

If the again picture change flag 233w is just not on but off (S7709: No), there is no picture data to be transferred, and the traditional picture transfer setting process is terminated as it is. Within the technique of S7707, it is determined whether or not or not the switch begin flag is on (S7707). As described above, by executing the conventional picture transfer process, the method corresponding to the display cease kind command is executed in the command determination course of executed earlier, and consequently, the show stop sort command is used. When the drawing listing is generated, the generated drawing record and the drawing goal buffer information specified by the drawing goal buffer flag 233j are transmitted to the picture controller (S7802). Then, after rearranging every sprite within the order of the sprite that should be positioned on the front facet from the sprite that should be positioned on the back side in the picture for one frame, the small print for every sprite in the order of the sprite after the rearrangement As a drawing information (detailed data), a drawing list is generated by describing a storage RAM sort and handle where sprite image data is saved, and parameters necessary for drawing the sprite.
