The short answer
Taking Odds is a secondary bet made behind a Pass Line wager after a point is established. It is the only bet in the casino that pays “True Odds,” meaning there is a 0.00% house edge.
The full calculation
The payout for an Odds bet is based on the mathematical probability of hitting the point versus rolling a 7.
- Point is 4 or 10: 3 ways to win, 6 ways to lose. True Odds are $2:1$. Payout is $2:1$.
- Point is 5 or 9: 4 ways to win, 6 ways to lose. True Odds are $3:2$. Payout is $3:2$.
- Point is 6 or 8: 5 ways to win, 6 ways to lose. True Odds are $6:5$. Payout is $6:5$. Because the $Payout = True Odds$, the Expected Value ($EV$) is exactly zero.
What this means at the table
While the Odds bet has no house edge, it increases your “volatility” (the size of your swings). If you bet $10 on the Pass Line and take $50 in Odds (5x Odds), you are wagering $60 total. The house edge only applies to the $10. This “dilutes” the total house edge on your money from 1.41% down to roughly 0.33%.
Common mistakes around this number
Many players make the mistake of betting more on the Pass Line and less on the Odds. To maximize your money, you should do the opposite: bet the table minimum on the Pass Line and put as much as you can afford (within table limits) on the Odds.

In Detail
Taking odds is the part of craps where the casino briefly stops overcharging you. Naturally, it makes you buy a ticket first.
This page is about adding true-odds money behind a line or come bet. 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. Odds pay 2:1 on 4/10, 3:2 on 5/9, and 6:5 on 6/8, so $EV_{odds}=0$. 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: Taking odds is one of the cleanest improvements a craps player can make, as long as the bankroll can handle it. 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 take odds mechanically if the amount makes you nervous. 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.
