Crapless craps looks attractive because you can’t lose on 2, 3, or 12 on the come-out roll—but the tradeoff is worse odds overall.
In standard craps, rolling a 2, 3, or 12 loses the pass line bet. In crapless craps, those numbers become point numbers instead.
The added point numbers (2, 3, 11, 12) are much harder to hit before a 7. This increases the house edge significantly.
The probability of rolling a 2 is 1 in 36. The probability of rolling a 7 is 6 in 36. This means you are far more likely to lose than win once these points are established.
Crapless craps offers more action but worse odds. It’s fun—but not optimal if your goal is minimizing house edge.
