Understanding Craps Odds

Craps odds are based on the 36 possible combinations when rolling two dice. The number 7 has the highest probability (6 ways, 16.67%) because it can be made with more combinations than any other total.

Pass Line vs Don't Pass

The Pass Line bet wins on come-out 7 or 11 and loses on 2, 3, or 12. Don't Pass is the opposite but pushes on 12 (some casinos 2) instead of winning. This push gives Don't Pass slightly better odds (1.36% vs 1.41%).

Frequently Asked Questions

What are the odds of rolling a 7 in craps?

A 7 can be rolled 6 ways out of 36 total combinations (1-6, 2-5, 3-4, 4-3, 5-2, 6-1), giving it a 16.67% probability - the highest of any total. This is why 7 wins on the come-out but loses after a point is established.

Which craps bet has the best odds?

The Don't Pass bet has the lowest house edge at 1.36%, followed by Pass Line at 1.41%. However, taking odds (which pay true odds with 0% house edge) is technically the best bet. Place 6 and Place 8 at 1.52% are also excellent choices.

What are true odds in craps?

True odds are payouts that exactly match the mathematical probability. For example, point 4 has true odds of 2:1 (3 ways to make 4, 6 ways to make 7). Taking odds behind Pass/Come pays true odds with zero house edge.

What bets should I avoid in craps?

Avoid proposition bets: Any Seven (16.67% edge), hardways (9-11%), and Big 6/8 (9.09%). These have the highest house edges in craps. Stick to Pass/Come with odds, or Place 6/8.

How do Come-Out roll odds differ from point odds?

On the come-out, Pass Line wins on 7/11 (8 ways, 22.2%) and loses on 2/3/12 (4 ways, 11.1%). Any other roll establishes a point. Once a point is set, odds depend on the point vs 7.
