The first passage includes a first ball outlet for discharging the game balls passing through the first passage within the lower tank. The second passage includes a second ball outlet for discharging the game balls passing through the second passage within the lower tank. Inside the lower tank, the first ball outlet is arranged at a height differing from that of the second ball outlet. |
