A Horn bet in craps is a one-roll proposition split across four numbers: 2, 3, 11, and 12. Each number is a separate bet. If one of those totals rolls, that part wins and the other three parts lose. If any other total rolls, the whole Horn loses.
Quick Facts
- A Horn covers 2, 3, 11, and 12.
- It is four separate one-roll proposition bets.
- A standard Horn amount should be divisible by 4.
- 2 and 12 usually pay more than 3 and 11.
- Only 6 of 36 dice combinations win somewhere on the Horn.
- The other 30 combinations lose the whole Horn.
- Horn bets are high-variance center action.
Plain Talk
A Horn bet sounds like broad coverage because it covers four totals. But the dice do not treat all totals equally.
The 2 has one combination. The 12 has one combination. The 3 has two combinations. The 11 has two combinations. That gives the Horn 6 winning combinations out of 36.
But the bet is not one pool of money. A $20 Horn is normally four $5 bets:
| Number | Amount |
|---|---|
| 2 | $5 |
| 3 | $5 |
| 11 | $5 |
| 12 | $5 |
If 11 rolls, only the 11 part wins. The 2, 3, and 12 parts lose.
That is the piece many beginners miss. The Horn pays on one number, not all four.

How It Works
The Horn bet is booked in the center of the layout. You give chips to the dealer and say, for example, “$20 Horn.”
The dealer books four equal bets.
| Roll | Common Name | Combinations | Horn Result |
|---|---|---|---|
| 2 | Aces | 1 | 2 part wins; other three lose |
| 3 | Ace-deuce | 2 | 3 part wins; other three lose |
| 11 | Yo | 2 | 11 part wins; other three lose |
| 12 | Boxcars | 1 | 12 part wins; other three lose |
| Anything else | — | 30 | Entire Horn loses |
Common payouts vary by table, but many layouts pay the 2 and 12 at 30:1 and the 3 and 11 at 15:1. Those payouts are still not true odds once the losing parts of the Horn are considered.
The Wizard of Odds craps basics shows Horn as part of the proposition family, and the Wizard of Odds house-edge appendix is useful for comparing the separate components. For the raw dice probability behind 2, 3, 11, and 12, see Wolfram MathWorld dice probability references.
Craps Table Example
You bet $20 Horn.
The dealer books:
| Horn Piece | Amount |
|---|---|
| Aces 2 | $5 |
| Ace-deuce 3 | $5 |
| Yo 11 | $5 |
| Boxcars 12 | $5 |
The next roll is 6-5, total 11.
The $5 Yo part wins. At 15:1, it pays $75 profit. The other three $5 pieces lose, for $15 lost.
Your net profit is $60.
That is why the Horn can feel strong when it hits. But if the next roll is 8, 9, 6, 4, 5, 7, or 10, the entire $20 loses at once.
From the Casino Side:
Horn bets are center bets. They require clear calls, proper placement, and fast payout memory from the crew.
The casino likes them because they resolve fast and carry high edge. The operational problem is clutter. A busy table can have Horns, Horn Highs, C and E bets, Any Seven, hardways, and hop bets all sitting in the center while players shout late instructions.
The stickman must control the pace. The base dealer must book the correct amount. The boxman watches whether a player is trying to sneak in after the dice are out.
For surveillance, the Horn is reviewable, but the call matters. “Horn,” “Horn high yo,” and “C and E” are not the same bet. Bad verbal control creates disputes.
Common Mistakes
- Thinking all four Horn numbers are paid when one hits.
- Betting an amount that does not divide cleanly by 4.
- Confusing Horn with C and E.
- Forgetting that 30 combinations lose the whole bet.
- Repeating Horn bets because one dramatic hit feels memorable.
- Not asking how the table pays 2 and 12.
- Treating Horn as a serious strategy instead of a high-risk side bet.
Hard Truth
A Horn bet sells four-number drama, but most rolls still wipe out the whole stack in one throw.
FAQ
What numbers are in a Horn bet?
2, 3, 11, and 12.
Is a Horn bet one bet or four bets?
It is four separate one-roll bets made with one call.
What does a $20 Horn mean?
Usually $5 each on 2, 3, 11, and 12.
What happens if 3 rolls on a Horn?
The 3 part wins. The 2, 11, and 12 parts lose.
What is Horn High?
Horn High means the Horn is still covered, but one chosen number gets extra money. Read Horn High Bets for that version.
Is Horn better than C and E?
Not automatically. They are different structures, but both are high-edge proposition action.
Is Horn a good come-out roll bet?
It can be used there, but it is still expensive compared with low-edge line bets.
Deeper Insight
Horn betting is a good example of why craps players should think in combinations, not just numbers.
A Horn covers four totals, but those four totals have only 6 combinations combined:
- 2 has 1 combination.
- 3 has 2 combinations.
- 11 has 2 combinations.
- 12 has 1 combination.
That means a Horn loses on 30 of 36 combinations.
When a Horn wins, the payout can be loud. Aces and boxcars can produce large-looking payouts. But large payouts are not the same as fair payouts. The casino sets the paytable below true odds, and three quarters of the individual Horn pieces lose even on a winning Horn roll.
This is also why Horns can create bankroll distortion. A player may remember one $20 Horn turning into a decent hit, while forgetting the ten Horns that died instantly. That memory bias is exactly why high-variance bets feel better than they are.
Use the variance simulator if you want to see the swing pattern. A Horn is not smooth. It is dead, dead, dead, hit, dead, dead, maybe big hit, then dead again.
Formula / Calculation
P(Horn hits any covered number) = 6 / 36 = 1 / 6
P(Horn loses entirely) = 30 / 36 = 5 / 6
For one Horn component:
P(event) = favorable dice combinations / 36
Expected Value = (Probability of Win × Net Win) - (Probability of Loss × Stake)
Expected Loss = Total Amount Wagered × House Edge
Formula Explanation in Plain English
A Horn has four pieces. Each piece has its own chance and payout. The whole call covers 6 of 36 dice combinations, but if one piece wins, the other three pieces normally lose. That is why the payout on a hit must be judged after subtracting the losing pieces.
