Betting the don't side means betting against the shooter — or more precisely, betting that a 7 will roll before the point repeats. It's a legitimate, mathematically sound way to play craps, with a slightly lower house edge than the pass line and an even better combined edge when you add lay odds. The main difference between the don't side and the pass side isn't mathematical. It's social.
Don't Pass vs. Pass Line: The Basic Math
The pass line carries a 1.41% house edge. Don't pass carries a 1.36% house edge. The difference is small but real, and it comes from the 12 push (bar) on the come-out roll.
On the come-out roll, don't pass loses on a 7 or 11 and wins on a 2 or 3. But a 12 is a push — no win, no loss. Without that bar, don't pass would have a player edge (you'd be winning more than the house), so the casino bars one number to maintain their advantage. Some tables bar the 2 instead; check the felt to confirm which.
Once a point is established, the dynamics flip from the pass side. Now you want a 7 to roll before the point — and the 7 is the most likely single number on the dice. If the point is 4, there are only 3 ways to roll a 4 vs. 6 ways to roll a 7. You have the better of it once the point is set. The cost is the disadvantage on the come-out roll.
Lay Odds: The Don't Side's Version of Free Odds
Just as pass line bettors can take free odds behind their bet, don't pass bettors can lay odds — an additional bet that the 7 will come before the point. Like free odds on the pass side, lay odds carry zero house edge and pay at true odds.
But the payout structure is reversed — because you're now the favorite (more 7s than points), you have to lay more to win less:
| Point | Lay odds payout | Why |
|---|---|---|
| 4 or 10 | 1:2 (lay $20 to win $10) | 7 is 2× as likely as 4 or 10 |
| 5 or 9 | 2:3 (lay $30 to win $20) | 7 is 1.5× as likely as 5 or 9 |
| 6 or 8 | 5:6 (lay $30 to win $25) | 7 is 1.2× as likely as 6 or 8 |
The combined house edge when you lay full odds:
- Don't pass only: 1.36%
- Don't pass + 1X lay odds: 0.68%
- Don't pass + 2X lay odds: 0.45%
- Don't pass + full lay odds (equivalent of 3-4-5X): ~0.27%
At maximum lay odds, the don't side edges out even pass line plus full free odds (0.37%) as one of the lowest house edges available anywhere in the casino.
Don't Come: The Come Bet Equivalent
Just as come bets extend the pass line approach to multiple numbers, don't come bets extend the don't pass approach. A don't come bet placed during the point phase works like a new don't pass bet — it wins on 2 or 3, loses on 7 or 11, pushes on 12, and establishes a point on any other number. Once it has a point, you want a 7 before that number repeats.
Running don't pass plus two don't come bets with lay odds is the don't-side equivalent of the 3-Point Molly — three numbers working simultaneously, all with zero-edge odds laid behind them.
The Social Reality at a Live Table
Most players at a craps table are betting the pass line — rooting for the shooter, cheering numbers, booing sevens. When you're on the don't side, you're cheering the opposite outcome. That friction is real at a live table.
A few things to know before you do it in person:
- Don't make a show of winning when the 7 rolls and the shooter sevens out. Pocket your chips quietly.
- Don't announce you're betting the don'ts in a way that rubs it in. "Taking the don't" is fine; making it a thing is not.
- At a cold table, nobody cares — the don't side isn't unusual when the shooter keeps sevening out. At a hot table with a table full of pass-line players riding a streak, it's more noticeable.
- The dealers don't care at all. The casino has no preference between pass and don't pass — the house edge exists on both sides.
None of the social friction changes the math. Betting don't pass is a legitimate, low-edge strategy. Whether the table dynamics at a live game are worth it is a personal call.
Don't Side vs. Pass Side: Which Is Better?
The honest answer: the don't side is slightly mathematically superior, but not meaningfully so in a practical session. The difference between 1.36% and 1.41% over 50 rolls is a few cents in expected loss. The real distinction is experiential — the don't side provides a different relationship with each roll, and for some players that's more engaging or more comfortable than riding with the shooter.
If you want to try it, start with small don't pass bets and no lay odds until the bet structure feels natural. The odds can wait until you've played a few sessions and know how you feel about the social dynamics of betting against the table.
