The short answer
The Don’t Come bet carries a house edge of 1.36%, making it mathematically superior to the standard Come bet.
The full calculation
The Don’t Come bet wins on a 2 or 3, loses on a 7 or 11, and pushes (standoff) on a 12. $P(win) = rac{3}{36} + ext{point wins} pprox 0.4793$ $P(loss) = rac{8}{36} + ext{point losses} pprox 0.4929$ $P(push) = rac{1}{36} pprox 0.0278$ $EV = (0.4793 imes 1) + (0.4929 imes -1) = -0.0136$ This results in a 1.36% house advantage.
What this means at the table
As a “Dark Side” player, you are the favorite to win once your bet moves to a number, because a 7 is more likely to roll than any individual point. On a $25 bet, your expected loss is just 34 cents. While the 0.05% difference between this and the Come bet is tiny, it represents the absolute minimum cost to play point-based craps.
Common mistakes around this number
The social mistake is cheering when the shooter “Sevens Out.” You will be the only one at the table getting paid. Mathematically, the mistake is taking your Don’t Come bet down once it moves to a number. Once it’s on a number, you have the advantage. The casino will happily let you take it back because you are surrendering a wager that is now worth more than its face value.

In Detail
The house edge on don’t come is small, quiet, and socially inconvenient — a very craps combination.
This page is about the price of wrong-way come betting. On the surface, that may sound like one small corner of craps, but in a real casino it touches the three things that decide whether a player survives the table: the written rule, the payout, and the way the bet feels when chips are already in action. Craps is dangerous for beginners because a bet can feel smart, social, or lucky while still being badly priced.
The math that matters: Two dice create 36 equally likely ordered combinations. The shape of the game comes from that grid: 7 has 6 combinations, 6 and 8 have 5 each, 5 and 9 have 4 each, 4 and 10 have 3 each, 3 and 11 have 2 each, and 2 and 12 have only 1 each. Don’t come is about 1.36% before lay odds. Lay odds are true odds but require more risk to win less. Expected value is the grown-up way to price a bet: $EV=\sum(P_i\times W_i)-\sum(P_j\times L_j)$. If the payout is smaller than the true probability deserves, the difference is the house edge.
What it means on the felt: For price-focused players, don’t come plus lay odds can be clean. The emotional cost is rooting against the table. A player who understands this subject does not need to act like a robot. You can still enjoy the noise, the shooter, the stick calls, and the little rush when the dice leave the hand. The point is to know when you are paying for entertainment and when you are making a lower-cost decision.
Casino-floor truth: Craps is built to move. The table crew wants clear bets, fast decisions, and clean payouts. The layout also nudges attention toward action. The safest-looking move is not always the cheapest move, and the loudest bet is almost never the best one. Good craps play is not about predicting the next roll. It is about refusing to overpay for it.
The mistake to avoid: Do not add large lay odds just because they are fair. Fair can still swing hard. Also, never judge this topic by one lucky hit or one ugly loss. Short sessions are noisy. The math only shows its face over repeated decisions, which is exactly why casinos are patient and players are usually not.
