Single Odds

Single odds is a craps term for the lowest standard level of free odds a casino allows on line bets. It means a player can add an extra odds bet up to the same amount as a Pass Line or Come bet after a point is set.

Players see this term on signs that say “1x odds” at live tables and in rules or help pages for online craps. It tells them the maximum size of the free odds bet that can sit behind a basic line wager.

How It Works

In craps, a round starts with a come-out roll. When the shooter rolls 4, 5, 6, 8, 9, or 10, that number becomes the point, which is the target that must repeat before 7 for Pass Line and Come bets to win.

After the point is set, the casino allows a separate free odds bet behind the Pass Line or on a Come bet. Under single odds, this bet can be no larger than the original line stake, so a $10 Pass Line bet supports up to $10 in odds, and that odds bet wins only if the point appears before 7\.

The odds portion pays at true mathematical odds that match the chance of the point beating 7\. Typical payouts are 2 to 1 on 4 and 10, 3 to 2 on 5 and 9, and 6 to 5 on 6 and 8, so the odds bet by itself has no house edge.

A short sequence shows how single odds works at the table:

Make a Pass Line bet before the come-out roll.
When a point is set, add odds up to the size of the Pass Line bet by placing chips directly behind it or using the odds button online.
If the point rolls before 7, the Pass Line pays even money, and the odds bet pays at the matching true odds.

Example in a Casino

At a live table, a player puts $10 on the Pass Line and the shooter rolls a 5, so 5 becomes the point. Under single odds, the player may add up to $10 in odds behind the line bet, and if 5 appears before 7, the Pass Line wins $10 while the odds bet pays 3 to 2 for $15, so the total return is $45 ($25 profit \+ $20 stake).

Online craps uses the same single-odds rule but handles chips and payouts automatically. The game tracks the point, offers an odds control once that number is set, and then applies the listed true-odds payouts when the point beats 7\.

Why It Matters

Single odds gives access to a free odds add-on bet that has no house edge on its own. The house still earns its usual percentage on the Pass Line or Come bet, but every dollar in the odds portion is mathematically neutral over the long term.

On a typical Pass Line wager, the house edge is about 1.41%. Adding single odds reduces the effective house edge on the total amount wagered to roughly 0.80–0.85%. The exact figure depends on how you calculate the combined edge, but either way, it makes Pass Line with single odds one of the best basic wagers in craps.
