What the Craps Odds Calculator Shows

It shows the payout, probability, house edge, and expected loss behind each selected craps bet. The point is not to predict dice. The point is to make the cost of the bet visible before you put money on the layout.

Why Free Odds Are Different

Odds bets behind pass, come, don’t pass, and don’t come pay true odds. That part has 0% house edge. The flat bet still has a house edge, so the combined edge drops only because the odds bet adds more money at fair odds.

Best Bets in Craps by House Edge

Pass line, don’t pass, come, don’t come, free odds, and place 6 or 8 are usually among the cleaner bets. They do not guarantee profit, but they usually cost less over time than the high-edge center bets.

Worst Bets in Craps

Any seven, hardways, horn-style bets, and many one-roll proposition bets carry high house edges. They can hit and feel exciting, but the math is expensive.

Important Warning

Craps odds do not remove risk. Lower house edge only means slower expected loss over time, not guaranteed profit.

Craps Odds Calculator FAQ

What is the best bet in craps?

Free odds have 0% house edge, but they must be attached to a pass, come, don’t pass, or don’t come bet. Among flat bets, pass line and don’t pass are usually among the better choices.

What is the worst bet in craps?

Any seven is one of the worst common bets, with a house edge around 16.67%.

Does taking odds remove the house edge?

No. The odds part has no house edge, but the required flat bet still does.

Why does the pass line still have a house edge?

Because the come-out and point rules slightly favor the casino over the full cycle of the bet.

Are place 6 and place 8 good bets?

They are among the better place bets, with a house edge around 1.52%.

Are hardways bad bets?

They are expensive bets. Hard 4 and hard 10 have a house edge around 11.11%, while hard 6 and hard 8 are around 9.09%.

What does expected loss mean?

Expected loss is the average mathematical cost of the bet over time. A $10 bet with a 5% house edge has an expected loss of $0.50 per bet.

Can this calculator predict dice rolls?

No. It only shows probabilities and payouts. Dice rolls are random.

Play smart. Gambling involves real financial risk. If the game stops being entertainment, it's time to stop playing.
