Craps offers some of the best odds in the casino—if you know what you are doing. It also offers some of the worst. For example, betting on the Pass Line carries a tiny 1.41% house edge, while betting on “Any 7” gives the casino a massive 16.67% advantage.
Use our free Craps Calculator to analyze the true cost of your bets. It specifically handles Pass Line Odds calculations, showing you how adding “Odds” behind your line bet dramatically reduces the casino’s effective edge.
How to Use the Calculator
- Select Bet Type: Choose your main wager (e.g., Pass Line, Place 6, Hard 8).
- Enter Flat Bet: The amount of your initial chip placement.
- Add Free Odds (Optional): If you select “Pass Line” or “Don’t Pass”, a new field will appear. Enter your Odds bet here.
- Tip: “Odds” bets pay true mathematical odds, meaning they have 0% House Edge.
- Calculate: Click the button to see your Expected Loss and the Effective House Edge.
Why You Should Always Take “Odds”
The secret to winning at Craps (or lasting longer) is the Free Odds bet. Look at the math:
- $10 Pass Line: House Edge is 1.41%.
- $10 Pass + $50 Odds: You have $60 at risk. The house edge on the $10 is 1.41% ($0.14). The house edge on the $50 is 0% ($0.00).
- Result: Your effective house edge drops from 1.41% down to roughly 0.23%. This is one of the lowest edges in the entire casino, rivaling Blackjack card counting.
Bets to Avoid (“Sucker Bets”)
According to the math, you should generally avoid the center of the table (Proposition Bets). Bets like Any 7, Hard 4/10, and Yo 11 carry high house edges ranging from 9% to 16%. Stick to the Line, Come Bets, and Place 6/8 for the best results.
