Frequently Asked Questions
What are proposition bets in craps?
Proposition bets (prop bets) are one-roll bets in craps placed in the center of the table. They include bets like Any Seven, Any Craps, specific numbers (2, 3, 11, 12), and hardway bets. They offer big payouts but have very high house edges.
Why are proposition bets considered bad?
Prop bets have house edges ranging from 9.09% (Hardways) to 16.67% (Any Seven). Compare this to the Pass Line at 1.41%. The high payouts are tempting but the odds heavily favor the house.
What is a hardway bet?
A hardway bet wins if the number is rolled as doubles (Hard 6 = 3-3, Hard 8 = 4-4) before a 7 or the "easy" way (any other combination). These stay active until they win or lose, unlike one-roll props.
What is the worst craps bet?
Any Seven has the highest house edge at 16.67%. It pays 4:1 but the true odds are 5:1 (6 ways to win, 30 ways to lose). Aces and Boxcars at 30:1 have 13.89% edge (true odds are 35:1).

How this works
Calculations follow the published mathematics of the game — combinatorics for cards, probability theory for dice, and expected-value accounting for wagers. Results are verified against independent references (primarily Wizard of Odds). No calculation here is an opinion or recommendation; it is arithmetic applied to the rules of the game.
