How the game works
The Field bet is a “one-roll” wager. You are betting that the very next toss of the dice will be a 2, 3, 4, 9, 10, 11, or 12. It is popular because it wins on seven different numbers and occupies a massive section of the layout. However, it is a mathematical trap designed to lure players who forget that the most frequent numbers (5, 6, 7, and 8) are all losers.
The basic rules
- Place your chips in the large “FIELD” area at any time.
- If the next roll is 3, 4, 9, 10, or 11, you win even money (1:1).
- If the next roll is 2, you win double (2:1).
- If the next roll is 12, you win either double or triple, depending on the house rules.
- If the next roll is 5, 6, 7, or 8, you lose.
- This is a “self-service” bet; you place and retrieve the chips yourself.
A typical hand/round
The shooter is getting ready to throw. You drop a $25 chip into the Field. The shooter tosses a 9. The dealer points to the field, and you pull your $25 profit and your original $25 bet back to your rack. You decide to try again. The shooter tosses a 6. Since 6 is not in the field, the dealer sweeps your $25 into the bank.
What’s different at different tables
The entire value of the Field bet hinges on the 12. Look at the felt. If it says “12 pays triple,” the house edge is 2.78%. If it says “12 pays double,” the house edge balloons to 5.56%. On the Las Vegas Strip, double-payouts are the norm, making the Field a terrible bankroll killer. Always look for the “3” in the 12 circle before placing this bet.

In Detail
The field bet is the potato chip of craps: quick, crunchy, and dangerously easy to keep reaching for without noticing the bag is gone.
This page is about one-roll betting on 2,3,4,9,10,11,12. 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. The field has 16 winning combinations and 20 losing combinations. If 2 and 12 both pay double, $EV=(18-20)/36=-5.56%$. If one pays triple, it improves to -2.78%. 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: The bet feels active because many numbers win, but the losing numbers include 5,6,7,8 — the heavy traffic of the dice grid. 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 call the field safe just because it covers many totals. 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.
