The odds bet is an extra craps wager you can make after a Pass Line, Don’t Pass, Come, or Don’t Come bet has a point. It pays true odds, so the odds portion has 0% house edge. That does not make it safe. It increases the money exposed to a seven-out.
Quick Facts
- You cannot make an odds bet by itself.
- It attaches to a Pass Line, Don’t Pass, Come, or Don’t Come bet.
- Pass/Come odds pay 2:1 on 4/10, 3:2 on 5/9, and 6:5 on 6/8.
- Don’t Pass/Don’t Come odds reverse those ratios.
- The odds portion has 0% house edge because it is paid at true odds.
- Casinos limit odds with rules such as 1x, 2x, 3-4-5x, 5x, 10x, or more.
- More odds lowers the blended edge but raises short-term bankroll swings.
Plain Talk
The odds bet is the cleanest piece of math on the craps table. The casino does not underpay it. If the true risk says the point should pay 2:1, the bet pays 2:1. If the true risk says 3:2, it pays 3:2.
That is unusual. Most casino bets pay less than true odds. That gap is the house edge. With odds, the gap is zero.
But players often twist that into a dangerous sentence: “Odds are free money.” No. Odds are fairly priced risk. Fair does not mean gentle.
A $10 Pass Line bet with $50 odds behind it can still lose $60 when a seven appears before the point. The odds part is not taxed by the house edge, but it is still exposed to the same dice.

How It Works
The odds bet starts only after a point exists.
For a Pass Line bet:
- You place a Pass Line bet before the come-out roll.
- The shooter rolls a point: 4, 5, 6, 8, 9, or 10.
- You place odds behind your Pass Line bet.
- You win the odds bet if the point repeats before 7.
- You lose the odds bet if 7 rolls first.
For a Come bet, the logic is the same after your Come bet travels to a number.
For Don’t Pass and Don’t Come, the bet works in reverse. You are betting that 7 appears before the point number. The payout is lower because your side is now more likely to win after the point is established.
| Point | Ways to roll point | Ways to roll 7 | Pass/Come odds payout | Don’t odds payout |
|---|---|---|---|---|
| 4 | 3 | 6 | 2:1 | 1:2 |
| 5 | 4 | 6 | 3:2 | 2:3 |
| 6 | 5 | 6 | 6:5 | 5:6 |
| 8 | 5 | 6 | 6:5 | 5:6 |
| 9 | 4 | 6 | 3:2 | 2:3 |
| 10 | 3 | 6 | 2:1 | 1:2 |
This is why the odds bet is tied directly to dice combinations. On a point of 4, there are 3 ways to roll the 4 and 6 ways to roll a 7. The casino pays 2:1 because losing combinations are twice the winning combinations.

Craps Table Example
You buy in for $200 and make a $10 Pass Line bet.
The come-out roll is 5. The dealer moves the puck to 5. You put $20 behind your Pass Line bet as odds.
Your action is now:
| Bet | Amount | What must happen | Payout if it wins |
|---|---|---|---|
| Pass Line | $10 | 5 before 7 | $10 |
| Odds behind Pass | $20 | 5 before 7 | $30 |
If the shooter rolls 5 before 7, you win $40 total profit: $10 from the Pass Line plus $30 from odds. Your $30 in original chips remains yours.
If the shooter rolls 7 first, you lose the $10 Pass Line and the $20 odds. One decision costs $30.
That is the real tradeoff. Better pricing, bigger exposure.
From the Casino Side:
The dealer cares about three things with odds: correct placement, correct maximum, and correct payout.
Behind a Pass Line bet, odds belong behind the line closer to the player. Behind a Come bet, odds are usually placed on top of or near the traveled Come bet, depending on house procedure. Don’t odds are positioned differently because the payout ratio is reversed.
The boxman or floor supervisor watches odds limits. A “3-4-5x” table does not mean the same max odds on every point. It usually means 3x on 4/10, 4x on 5/9, and 5x on 6/8 so the maximum win is similar across points.
Surveillance likes odds because they are visible and procedural. The risk is not math confusion for the casino. The risk is dealer error: wrong cap, wrong odds multiple, wrong payout, or a late odds bet accepted after the dice moved.
Common Mistakes
- Thinking 0% house edge means no risk.
- Taking maximum odds with a bankroll too small for normal variance.
- Confusing the main craps odds page with this specific odds bet.
- Forgetting that the base line bet still has house edge.
- Putting odds in the wrong place and slowing the dealer.
- Asking for odds after the dice are already out.
- Taking odds because the table is loud, not because the bankroll can handle it.
Hard Truth
The odds bet is fair. Craps is not. The fair part sits on top of a base bet that still belongs to the casino, and the dice do not care that your payout is mathematically clean.
FAQ
Is the odds bet really 0% house edge?
Yes, the odds portion is paid at true odds. The base Pass Line, Don’t Pass, Come, or Don’t Come bet still has its normal house edge.
Can I make an odds bet without a Pass Line or Come bet?
No. Odds must attach to an eligible line or come-type bet after a point exists.
Should beginners always take odds?
Not always. Beginners should first understand the flow and protect their bankroll. A small odds bet is better than maximum odds with nervous money.
What does 3-4-5x odds mean?
It usually means you may take 3x odds on points 4/10, 4x on 5/9, and 5x on 6/8.
Why do casinos offer a 0% house-edge bet?
Because it must attach to a base bet with house edge, it increases total action, and it makes the game more attractive to informed players.
Do odds bets count for comps?
Usually less than regular house-edge action, and sometimes not at all in the same way. Casino rating systems often value theoretical loss, not just chips on the layout.
Can odds bets overcome the Pass Line house edge?
No. They reduce the blended edge on total money at risk, but they do not turn the total package into a player advantage.
Deeper Insight
The odds bet is where craps exposes a difference many players never learn: price and risk are not the same thing.
The price is excellent. The risk is still real.
A point of 4 has 3 winning combinations and 6 losing seven combinations. That is why true odds pay 2:1. If you bet $10 in odds on the 4, a fair win pays $20. Over time, the larger but less frequent wins balance the more frequent losses.
A point of 6 has 5 winning combinations and 6 losing seven combinations. The fair payout is 6:5. You win less per hit because the 6 is easier to roll than the 4.
The mistake is to think “more odds” always means “smarter play.” Mathematically, yes, more odds lowers the combined percentage edge on the total wager. Practically, more odds increases the size of each resolved decision. A player with a $100 bankroll who bets $10 Pass plus $50 odds is not playing a gentle low-edge game. He is risking 60% of the bankroll on one point cycle.
Use the expected loss calculator to separate house edge from total action. Use the variance simulator when you want to see how ugly a fair bet can look in a short session.
Formula / Calculation
P(event) = favorable dice combinations / 36
True Odds Payout = Losing Combinations / Winning Combinations
Expected Value = (Probability of Win × Net Win) - (Probability of Loss × Stake)
For $10 odds on point 4:
- P(4 before 7) = 3 / (3 + 6) = 3 / 9
- P(7 before 4) = 6 / 9
- Win amount = $20
- Loss amount = $10
EV = (3/9 × $20) - (6/9 × $10) = $6.67 - $6.67 = $0
Formula Explanation in Plain English
On a point of 4, the seven is twice as likely as the 4. A fair bet must therefore pay twice as much when the 4 wins. That is exactly what 2:1 odds does. The casino gives you a fair price, but you still lose more often than you win on that point.
