As described above, the SRB is called a so-called shift RB, and starts on the condition that the RB shift lottery is won.

It should be noted that the SRB start condition may be that the combination of RB transition symbols is aligned.
Each SRB as a unit ends when the maximum number of winnings (for example, 2 to 3 times) is reached.
During one SRB, all the SRB transition lotteries including the one SRB are performed, and when the SRB transition lottery is won during the one SRB, the next combination of winning SRB transition symbols is not arranged, After the end of the one SRB, the next winning SRB is continuously started.

Note that although all SRB transition lotteries including the one SRB are performed during one SRB, the present invention is not limited to this, and other SRB transition lotteries other than the one SRB may be performed.
