sic bo rules
A three-dice game of betting on totals and combinations
Sic bo is a dice game where three dice are rolled and you bet on the result — the simplest bets are "Small" (a total of 4–10) and "Big" (11–17), each paying even money. Beyond those you can bet on exact totals, single numbers, pairs and specific three-dice combinations, with payouts that rise as the bet gets less likely.
It's a pure game of chance — no decisions once the dice are shaken. Below are the main bet types. For a two-dice game built around one core bet, see craps rules.
Small and Big
The beginner bets are Small (total 4–10) and Big (total 11–17), each paying 1:1. Both usually lose on any triple (all three dice the same), which is where the house edge comes from. These even-money bets are the easiest way to start.
Single numbers and totals
You can bet that a specific number (1–6) appears on one, two or all three dice — paying more the more times it shows. You can also bet on an exact total (from 4 to 17); rarer totals pay much more than common ones. The payout always tracks the probability: less likely means a bigger return.
Combinations and triples
Other bets cover two-dice combinations, any pair, a specific triple (a huge payout because it's so rare) or any triple. The exotic bets look tempting but carry a higher house edge, so the Small/Big bets remain the sensible starting point. For a lottery-style game of chance, see keno rules.

Frequently asked questions
What are the best bets in sic bo?
The even-money Small (4–10) and Big (11–17) bets have the lowest house edge and are the sensible starting point. The exotic single-number and combination bets pay more but carry a higher edge.
Why do Small and Big lose on a triple?
A triple (all three dice the same) is treated separately, and Small/Big bets typically lose on it. That rule is where the house gets its edge on these even-money bets.
Is there any skill in sic bo?
No. Once the dice are shaken the result is random. Your only choice is which bets to place, and the payouts always reflect the odds.
