When game balls entering the second major winning hole pass through the special area in both of the two special ball entry games, both of an electric-tulip supported state (high-frequency state) and a probability variation state are allowed to occur after completion of the jackpot game. When the game balls entering the second major winning hole do not pass through the special area in one or both of the two special ball entry games, neither the electric-tulip supported state nor the probability variation state is allowed to occur after the completion of the jackpot game. |
