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.
- State the amount and number clearly and deliver the chips where the stickperson directs, keeping clear of established center wagers.
- 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 an extra unit to 11 within the wager that was named, so the base wager matters. A $5 Horn High Yo is $1 on 2, $1 on 3, $2 on 11, and $1 on 12. A separate $5 two-number call covering only 3 and 11 could instead mean $2 on 3 and $3 on 11. Name the wager and state the split if there is any doubt.
Two $5 calls that settle differently
With a $5 Horn High Yo, an 11 makes the $2 Yo component earn $30 at 15 to 1 while the three $1 components lose. Net profit is $27, and the winning $2 stake is still the player’s money. If 3 rolls instead, the $1 winner earns $15 while the other $4 loses, for $11 net profit.
With a $5 two-number split of $2 on 3 and $3 on 11, an 11 earns $45 while the $2 on 3 loses, for $43 net profit. A 3 earns $30 while the $3 on 11 loses, for $27 net profit. Totals 2 and 12 lose the complete $5 because neither is covered.
Both calls can put the larger share on 11, but they cover different results and cannot share one payout key. Before the dice move, repeat the number set and chip allocation: four-number Horn High Yo, or a two-number 3/11 split.
Price a “for one” layout before betting
A $1 bet on 12 paid at 30 for 1 returns $30 including the stake, so its profit is $29. One winning combination earns $29 and 35 losing combinations cost $35: an expected $6 loss across $36 wagered, or 16.67%. A 31-for-1 return instead equals the standard 30-to-1 profit payout and its 13.89% edge.
Likewise, a $1 Eleven paid at 15 for 1 earns only $14 profit. Its two winning combinations earn $28 against $34 lost, again giving a 16.67% edge. A 16-for-1 return equals 15 to 1 and gives 11.11%. Ask for the total payment on a $1 win if the wording is unclear, then check it with the payout auditor. A familiar number printed beside a bet is insufficient without the return convention.
