The objective in Double Ball Roulette is to predict the number or numbers on which two balls will come to rest. The wheel includes the numbers 1-36 plus a single 0 (zero).
Game Rules
After the time allotted for betting has expired, two balls are released by a device. The balls travel in the same direction and at the same speed, but one always trails the other. Each ball eventually comes to rest in a numbered pocket within the wheel. The balls may land in the same or in different pockets.
