One-roll proposition guide · Reviewed August 18, 2026
Exact bets on 2, 3, 11, or 12 cover one total for one roll. Under common 30-to-1 and 15-to-1 payouts, their house edges range from 11.11% to 13.89%.
Sam’s verdict
These are easy to call and exciting to hit, but the payout is materially below the true price. Know that each chip is a fresh one-roll wager, not a standing prediction.
Rules, calls and standard math
| Total | Common call | Ways | True odds against | Common net payout | House edge |
|---|---|---|---|---|---|
| 2 | Snake eyes / aces | 1 | 35 to 1 | 30 to 1 | 13.89% |
| 3 | Ace-deuce / acey-deucey | 2 | 17 to 1 | 15 to 1 | 11.11% |
| 11 | Yo / yo-leven | 2 | 17 to 1 | 15 to 1 | 11.11% |
| 12 | Boxcars / midnight | 1 | 35 to 1 | 30 to 1 | 13.89% |
“Yo” is useful in a noisy casino because “eleven” can sound like “seven.” Calls and slang vary, so a plain number is always acceptable.
How the house edge is calculated
For a $1 bet on 12 at 30 to 1, one combination wins $30 and 35 lose $1. Expected result across 36 trials is $30 − $35 = −$5. Divide $5 by $36: 13.89%.
For a $1 bet on 11 at 15 to 1, two combinations win $15 and 34 lose $1. Expected result is $30 − $34 = −$4 across $36 of action, or 11.11%.
“To 1” versus “for 1”
A 30-to-1 win earns $30 plus return of the original $1. A 30-for-1 return includes the original chip and earns only $29 net. Read the table’s wording; using the wrong convention understates the edge.
Making the bet at a live table
- Wait until the stickperson is accepting center action.
- Toss—not hand—the chips into the layout and state the amount and number clearly.
- The stickperson places the wager in the correct proposition box and player position.
- The next legal roll settles it. Repeat the call and fund a new wager if you want it again.
The minimum may be a single low-denomination chip, but that is a house decision rather than a universal rule.
How these bets combine
A Horn divides action among 2, 3, 11, and 12. Three-Way Craps covers 2, 3, and 12. A C&E divides action between Any Craps and 11. The name does not turn the components into a new dice event.
What does “high on the yo” mean?
It allocates the extra unit to 11. For example, a $5 call covering 3 and 11 “high on yo” can mean $2 on 3 and $3 on 11. State the split if there is any doubt.
