KEY TAKEAWAYS
Sic Bo is a casino dice game played with three dice, in which players bet on what the dice will show after a dealer shakes them. The simplest bets are Big and Small: Big wins if the three dice total 11 to 17, Small wins on a total of 4 to 10, and both lose if all three dice show the same number, called a triple. Both bets pay 1 to 1.
That triple rule is where the house edge comes from. Of the 216 possible outcomes with three dice, 6 are triples, and 6 in 216 is 2.78%, which is exactly the house edge on Big and Small. Other bets on the layout, such as single numbers and triples, are more tempting and more expensive, with edges from about 7.87% to about 30% at the payouts used in this guide.
This guide explains the Sic Bo rules step by step, shows a few worked examples, and compares what each bet pays and costs. Layouts differ between casinos, so paytables are flagged.
The Basic Rules of Sic Bo
Sic Bo uses three six-sided dice, and three dice produce 6 × 6 × 6 = 216 equally likely combinations. A dealer shakes the dice, often in an enclosed cage or shaker, and the result decides every bet on the layout at once. Players place chips on the areas that match the results they are betting on.
Sic Bo is a house-banked game, so players bet against the casino, not each other, and any number of players can bet on the same roll. Most tables use a posted layout with a minimum and maximum bet for each type of bet, and the placard at the table shows those limits.
The layout contains many areas, but they fall into a few groups: Big and Small, single numbers, combinations of two numbers, totals, and triples. Every bet is settled by a single roll, so there is no point to make and no second stage, which keeps the rules short. For a plain-English explanation of why every bet carries a cost, see the house edge explained.
The key rule to remember is the triple. A triple makes Big and Small lose together, even if the total falls inside the range. That single rule is why those bets are not even money in practice.
How a Round of Sic Bo Works: The Main Bets
Big and Small
These are the simplest bets. Small wins on a total of 4 to 10 and Big wins on 11 to 17, unless the dice show a triple. Both pay 1 to 1. Totals of 3 and 18 are the triples 1-1-1 and 6-6-6, which lose on both bets. Of the 216 combinations, 105 win for Big and 105 for Small.
Single number bets
A single number bet wins if the chosen number appears on at least one die. The payout depends on the number of matching dice: 1 to 1 for one match, 2 to 1 for two matches and 3 to 1 for three matches. Of the 216 combinations, 125 show no match, 75 show one, 15 show two and 1 shows three.
Triple bets and other bets
A specific triple, such as three 4s, wins only if that exact triple appears. Any triple wins on any of the six triples. These bets pay large odds on rare outcomes, commonly 150 to 1 on a specific triple and 24 to 1 on any triple, though casinos set their own paytables. The layout also offers bets on totals and on pairs of numbers.
Worked Examples: A Big Win, a Number Bet and a Triple
Suppose the dice show 2, 4 and 6, a total of 12. The dice are not a triple, and 12 is in the range 11 to 17, so Big wins. A $10 bet on Big wins $10 at 1 to 1, and a $10 bet on Small loses.
Now suppose a player bets $10 on the number 4 and the dice show 4, 4 and 6. Two dice match the chosen number, so the bet pays 2 to 1, which is $10 × 2 = $20 profit. If only one die had shown a 4, the profit would be $10, and if none had, the bet would lose $10.
Finally, suppose the dice show 5, 5 and 5, a total of 15. The total falls inside the Big range, but the triple makes Big and Small both lose. A $10 bet on the number 5 wins $30 at 3 to 1 because all three dice match, and a $10 bet on a specific triple of 5s at 150 to 1 would win $1,500, while a bet on any triple at 24 to 1 would win $240.
Sic Bo Payouts and House Edge by Bet
Each Sic Bo bet pays less than its true odds, and the gap is the house edge. Big and Small are the lowest-cost bets on the layout, because they lose only on triples. The table below uses the payouts described above, which vary by casino.
| Bet | Payout | Chance of winning | House edge |
|---|---|---|---|
| Big or Small | 1 to 1 | 105 in 216 (48.61%) | 2.78% |
| Single number | 1, 2 or 3 to 1 | 91 in 216 (42.13%) | 7.87% |
| Any triple | 24 to 1 | 6 in 216 (2.78%) | 30.56% |
| Specific triple | 150 to 1 | 1 in 216 (0.46%) | 30.09% |
The triple bets cost more than ten times as much as Big or Small, even though their payouts look generous. In money terms, $1,000 wagered on Big or Small costs about $27.80 on average, compared with about $78.70 on single numbers and about $300.90 on a specific triple at 150 to 1. Casinos that pay more on triples lower those edges, so the posted paytable decides what applies.
Common Sic Bo Mistakes and Myths
The costliest habit is betting triples because of the large payout. A specific triple wins 1 time in 216, and the payout is not large enough to compensate, so the average cost is about 30% of each bet at the payouts shown above.
The second mistake is thinking the total decides Big and Small, as in “15 is big, so Big wins”. The triple rule overrides the total, and ignoring it makes Big and Small look like fair bets when they carry a 2.78% edge.
A third is believing that recent results show which side is “due”. Each roll is independent, so a long run of Small does not make Big more likely on the next roll. Scoreboards that show past results describe history, not what will happen next.
Finally, no betting system changes the cost. Raising bets after a loss only changes the size of the swings, and table maximums limit how far any system can go, while the house edge stays where it was on every bet.
What to Check at the Table
Before playing, read the layout and check the payouts for single numbers, totals and triples, because paytables differ between casinos and even between tables. Also check the minimum bet and the maximum bet, since limits can differ for each type of bet.
Place chips in the correct area and wait for the dealer to call the result. Do not touch the chips after the dice are shaken, and ask the dealer if a bet or a payout is unclear before betting. Electronic versions of the game follow the same basic rules, but the payouts shown on screen are the ones that apply.
Set a budget before the first roll and stop when it is spent. Stay with Big or Small if the aim is to keep the average cost low, and treat even those as the price of entertainment. No pattern or system turns Sic Bo into a way to make money.
What to Learn Next
Once the Sic Bo bets are clear, the natural next step is to compare them with another dice game. Craps uses two dice instead of three, and how craps works, with its dice probabilities shows a table where the best bets cost about half as much as Big or Small.
From there, a side-by-side comparison of casino games puts the 2.78% edge in context, and the house edge explained earlier in this guide applies to every other game on the floor.
