Frequently Asked Questions

What is a horn bet in craps?

A horn bet is a single bet that covers 2, 3, 11, and 12 simultaneously. It requires 4 units (one on each number) and wins if any of these numbers roll. The payout depends on which number hits, minus the losing units.

What is a horn high bet?

A horn high bet is a 5-unit horn where one number gets 2 units instead of 1. "Horn high yo" means 2 units on 11, 1 each on 2, 3, and 12. This increases payout if your high number hits.

What is the World/Whirl bet?

The World bet (or Whirl) is a 5-unit bet: 1 unit each on 2, 3, 7, 11, and 12. If 7 rolls, you break even (push). Any other horn number pays its normal amount minus the 4 losing units.

Why is the horn bet considered bad?

The horn bet combines four high house edge bets into one. Combined house edge is about 12.5%. You are essentially making multiple bad bets at once. Compare to Pass Line at 1.41%.
