How bubble craps works
A bubble craps machine has a clear dome containing two dice. Players place bets using a touchscreen or physical buttons. When everyone has finished betting, the machine shakes the dome or uses an air jet to tumble the dice, then reads the result electronically. The machine automatically calculates and pays winning bets, and the next round begins.
The game follows standard craps rules: the shooter (selected by the machine) rolls until a point is made or a seven-out occurs. The key difference is that no human handles the dice, and the machine enforces all rules and payouts.
Example: the Pass line bet
On a bubble craps machine, a player places a Pass line bet before the come-out roll. If the dice show 7 or 11, the bet wins even money. If they show 2, 3 or 12, the bet loses. Any other number becomes the point, and the machine continues rolling until the point repeats (win) or a 7 appears (loss). The machine handles all payouts automatically.
