PROBLEM TO BE SOLVED: To enhance expectations felt by players for big bonuses during the internal winning. SOLUTION: The machine is provided with a start switch 21 for starting the rotation of reels, a random number generation means 22 for generating random numbers sequentially, a lottery means 23 which performs an internal lottery to pick up one random number from among those thus generated, a table having winning domains among domains to which all of the random numbers belong, a comparison means 25 which compares the random number picked up by the internal lottery with those in the table to judge the winning or losing of the random number picked up and a control means 26 which controls the rotation of the reels to let specified figures line up at each winning, corresponding to the role won to match a winning signal as given when the comparison means 25 determines the winning. The lottery means 23 performs the internal lottery as well in the normal ordinary game during the internal win and the comparison means 25 uses a table containing a BB winning domain among the winning domains for the judging of the winning or losing with respect to the one random number picked up by the internal lottery. Thus, even during the internal win, the lottery picks up the BB to make winning possible.
