How Craps Odds Bets Work
What this guide covers
Odds bets are the single most important concept in craps value — the only bet anywhere in a standard casino with zero built-in house edge. This guide covers exactly how they work, their full payout structure, and how to use them to meaningfully lower your overall cost of play. For where odds fit into the broader betting menu, see craps betting guide; for how they factor into strategy, see craps strategy guide.
What an odds bet is
An odds bet is an additional wager you can place behind an existing pass line, don't pass, come, or don't come bet, once a point has been established. Unlike every other bet at the table, odds pay out at true mathematical probability with no adjustment built in for the house — meaning, over a large enough sample, this specific portion of your wager has an expected value of exactly zero, neither costing nor earning you money on average.
Why odds bets carry zero house edge
Every other craps bet's payout is deliberately set slightly below true odds, which is precisely where the house edge comes from. Odds bets are the one exception — casinos offer them specifically to add excitement and depth to the game without providing a way to profit from this specific side wager, relying entirely on the accompanying line or come bet (which does carry a house edge) to generate revenue.
Pass line and come odds payout table
| Point | Payout |
|---|---|
| 4 or 10 | 2:1 |
| 5 or 9 | 3:2 |
| 6 or 8 | 6:5 |
These ratios reflect the true probability of each point number repeating before a 7 — a 4 or 10 is genuinely half as likely to repeat as a 7 is to appear, hence the 2:1 payout, and so on down the table.
Don't pass and don't come odds payout table
Don't pass and don't come odds pay the inverse ratios, since you're betting on the opposite outcome (a 7 appearing before the point): 1:2 on points of 4 or 10, 2:3 on points of 5 or 9, and 5:6 on points of 6 or 8. Like pass line odds, these carry zero house edge — the inverse ratio structure exactly reflects the true probability of the opposite outcome.
How to place an odds bet
Once a point is established, you place additional chips directly behind your existing pass line or don't pass bet (or, for come/don't come bets, in the corresponding position once that bet establishes its own point). Online interfaces typically handle this with a clearly labeled "add odds" option once a point is active, making the process straightforward even for a first-time player.
Maximum odds multiples
Casinos limit how large an odds bet can be relative to your original pass line or come wager, expressed as a multiple — common structures range from 1x (a modest limit) up to 10x or higher at more generous tables, sometimes with different multiples for different point numbers (a tiered structure discussed further in craps rules explained). Checking a specific table's posted maximum odds before playing seriously directly affects how much zero-edge value you can access.
Why a larger odds multiple lowers your blended house edge
Because odds carry zero edge, a larger odds bet relative to your line bet dilutes your overall house edge across the combined wager. A $10 pass line bet alone carries 1.41% house edge. Add $10 in odds (1x), and your blended edge across the $20 total drops to roughly 0.85%. Add $50 in odds (5x), and your blended edge across the $60 total drops to roughly 0.33%. The math is straightforward: more of your total stake sitting in the zero-edge portion means a lower overall cost.
Worked example at a 3x odds table
Suppose you bet $10 on the pass line at a table offering 3x odds, and the point becomes 5. You add $30 in odds, paying 3:2 if 5 repeats before a 7. If it does: your $10 pass line bet wins $10 at even money, and your $30 odds bet wins $45 at 3:2, for a total profit of $55 on a $40 total stake — a blended return considerably better than the pass line bet's 1.41% edge would suggest in isolation.
Odds bets on come and don't come
Once a come or don't come bet establishes its own point (following the same mechanics as pass line and don't pass, covered in come bet vs don't come bet), you can back it with odds exactly the same way — same payout ratios, same zero house edge, same maximum multiple rules. This means an active player running several simultaneous come bets can have considerably more zero-edge action working than a single pass line bet alone would provide.
Removing or adjusting odds bets
Unlike the pass line or come bet they're attached to, odds bets can typically be removed or reduced at the player's discretion at any point before the round resolves — a genuine flexibility difference from the firmly locked-in bet they support. This lets you reduce your odds exposure mid-round if your risk tolerance or bankroll plan changes, without needing to abandon the underlying line bet itself.
Why odds bets alone can't be placed
It's worth being clear that odds bets are never available as a standalone wager — they can only supplement an existing pass line, don't pass, come, or don't come bet. This is precisely why the underlying line bet's small house edge is unavoidable even for a player maximizing odds: you can dilute that edge significantly, but you can't eliminate it entirely without also eliminating the bet odds are attached to.
Frequently asked questions
Why do odds bets carry zero house edge? Because their payout ratios are set at exactly true mathematical probability, with no adjustment built in for the house — a deliberate exception among craps bets, whose payouts are otherwise set slightly below true odds.
How much can I bet in odds? It depends on the table's posted maximum odds multiple relative to your original pass line or come bet — commonly 2x to 10x, sometimes varying by which specific point number is active.
Does a larger odds bet actually reduce my cost of play? Yes — since odds carry zero edge, a larger odds bet relative to your line bet lowers your blended house edge across the total amount wagered.
Can I place an odds bet without first having a pass line bet? No — odds bets only exist as a supplement to an existing pass line, don't pass, come, or don't come bet; they're never available as a standalone wager.
Can I remove my odds bet if I change my mind? Yes, typically — unlike the line bet it supports, an odds bet can usually be reduced or removed at the player's discretion before the round resolves.
Do odds bets work the same way on come bets as on pass line? Yes — once a come bet establishes its own point, it can be backed with odds using identical payout ratios and the same zero house edge as pass line odds.
