Craps Strategy — How to Play with the Lowest House Edge
Optimal craps strategy: why pass line plus maximum odds is the best play, how free odds eliminate the house edge, the danger of proposition bets, and bankroll management for craps sessions.
Craps has a reputation for complexity, but the optimal strategy is simpler than almost any other table game: make the bets with the lowest house edge and take maximum odds. That is the entire strategy. Everything else — complex systems, hedge bets, spreading chips across the layout — adds cost without adding value.
The core play: pass line plus maximum odds
The pass line carries a house edge of 1.41%. On its own, that is already one of the better bets at any casino. But the pass line becomes genuinely powerful when combined with the odds bet placed behind it after the point is established.
The odds bet pays at true mathematical odds — meaning the casino has zero edge on that portion of your money. A 4 or 10 as the point pays 2:1. A 5 or 9 pays 3:2. A 6 or 8 pays 6:5. These are exactly the correct probabilities, so no house advantage is built into the payout.
When you take maximum odds, the combined house edge on your total money wagered drops dramatically:
| Table odds | Combined house edge (pass + odds) |
|---|---|
| 1x odds | 0.85% |
| 2x odds | 0.61% |
| 3x–4x–5x odds | 0.37% |
| 10x odds | 0.18% |
| 100x odds | 0.02% |
The practical implication is clear: if a casino offers 3x–4x–5x odds (the most common structure, where you can take 3x on a 4 or 10, 4x on a 5 or 9, and 5x on a 6 or 8), your effective house edge on the total bet drops to just 0.37%. That is competitive with well-played blackjack and better than any slot machine.
Don’t pass as an alternative
The don’t pass bet has a marginally lower house edge than the pass line — 1.36% versus 1.41% — because the 12 on the come-out roll pushes rather than losing. You can similarly take odds on don’t pass, which also pay at true odds (in the reverse direction: 1:2 on a 4 or 10, 2:3 on a 5 or 9, 5:6 on a 6 or 8).
The practical difference between pass and don’t pass is small. Choose whichever you prefer. The “wrong way” label attached to don’t pass players is social, not mathematical.
Adding come bets with odds
Some players extend the strategy by placing come bets once a point is established, then taking odds on each come bet as it travels to a number. This gives you multiple numbers working simultaneously with zero-edge odds behind each one. The house edge remains the same per dollar wagered, but more of your money is out on zero-edge bets, which is mathematically fine. The risk is that a 7-out resolves all your come bets against you at once, so this approach requires a larger session bankroll.
Why proposition bets are expensive
The proposition bets in the centre of the layout — any seven, any craps, hardways, yo — carry house edges between 9% and 16.67%. To put that in perspective: the any seven bet (4:1) has a 16.67% house edge. That means the casino expects to keep $16.67 of every $100 wagered on it over time. The pass line edge of 1.41% means they expect to keep $1.41. Proposition bets cost roughly 10–12 times more per dollar than the pass line. They exist because the big payouts are exciting, not because they are a sensible use of your money.
Bankroll management for craps
Craps moves faster than many table games, and having multiple bets active simultaneously means variance can swing both ways quickly. Practical guidelines for a session:
- Set a loss limit before sitting down. Decide in advance the maximum you are comfortable losing in a session, and leave when you hit it.
- Size your pass line bet relative to your bankroll. If you plan to take 3x–4x–5x odds, your total exposure per point can be 4–6x your base bet. A $10 pass line bet with 5x odds on a 6 or 8 means $60 at risk on that point. Size accordingly.
- Do not chase losses. Increasing bet size to recover losses is the fastest route to an empty bankroll. The math does not change based on recent outcomes.
- The house edge cannot be overcome by systems. Martingale, Iron Cross, and other betting patterns do not change the expected value of any bet. They restructure when you win and lose, but they cannot remove the house edge from the equation.
The mathematics of craps are well-defined and actually quite favourable for a casino game — provided you stick to the right bets.
