Walk through any casino floor in Macau or Singapore and you will hear it before you see it: the rattle of three dice inside a glass shaker, followed by a pause while the illuminated layout lights up the winning areas. Sic bo — the name means “precious dice” in Cantonese — is one of the oldest and most popular games in Asian casinos, and one of the easiest to learn.
It is also a game where the house edge swings enormously depending on where you put your chips. The same table offers a bet with an edge below 3% and others with edges above 15%, sometimes separated by a few centimetres of felt. This guide explains the dice, the main bets and the arithmetic behind them. It does not offer a way to beat the game, because there isn’t one.
How a round works
Players place chips on the layout, which is divided into areas for different outcomes. When betting closes, the dealer shakes the three dice inside a covered container — or an automated shaker does it — and reveals the result. The layout lights up every winning area, the dealer collects losing bets and pays winners according to the table’s payout schedule.
Three dice produce 216 equally likely combinations (6 × 6 × 6). Every bet on the table is simply a claim about which of those combinations will appear, and every payout is set a little below what the true odds would justify. That gap is the house edge.
Small and big
The most popular bets are small (a total of 4 to 10) and big (a total of 11 to 17). Both pay even money. The catch is that both lose on any triple — three ones, three twos and so on — even when the total would otherwise fall in range. That rule is where the house edge comes from.
Of the 216 combinations, 105 win for small, 105 win for big, and the six triples lose for both. The expected loss is therefore 6/216, or about 2.78% of each bet. Odd and even bets work in the same way, with triples losing, and carry the same edge.
Total bets
Total bets predict the exact sum of the three dice, from 4 to 17. Totals near the middle (10 and 11) are the most likely; extremes (4 and 17) are rare. The payouts reflect this, but not generously. Depending on the casino’s payout schedule, the house edge on totals can range from under 10% to above 25%.
This is the area of the layout where payout tables differ most between casinos — and sometimes between tables in the same casino. Always read the printed payouts on the layout before you bet.
Triples, doubles and combinations
A specific triple (for example, three fives) is the longest shot on the table, with a probability of 1 in 216. Payouts of 150:1 or 180:1 are common, well below the true odds of 215:1, giving house edges of roughly 16% to 30%. The “any triple” bet pays around 24:1 to 30:1 on a 6-in-216 chance, which is similarly expensive.
Specific doubles (at least two of a chosen number) and two-dice combinations (two chosen numbers appearing) sit in between. Their edges depend heavily on the payout schedule.
Single-number bets
A single-number bet wins if the chosen number appears on one, two or three of the dice, paying 1:1, 2:1 or 3:1 respectively in the most common schedule. The probability of at least one match is about 42%, but the payout structure produces a house edge of about 7.9%. Some casinos pay more for three matches, which lowers the edge.
Speed, cost and staying in control
Sic bo rounds are quick, and electronic versions are quicker still. Because the house edge applies to every bet, the number of rounds per hour matters as much as the edge itself. A 2.78% edge on small or big, repeated over many rounds, adds up to a substantial expected cost.
Set a budget before you sit down, treat it as the cost of entertainment, and leave when it is spent. Patterns on the electronic results board are a record of past rolls and do not predict future ones — every roll is independent.
At a glance: common sic bo bets, typical payouts and house edge
| Bet | Wins on | Typical payout | Approx. house edge |
|---|---|---|---|
| Small / big | 105 of 216 combinations | 1:1 | 2.78% |
| Odd / even | 105 of 216 combinations | 1:1 | 2.78% |
| Single number | Number on 1, 2 or 3 dice | 1:1 / 2:1 / 3:1 | 7.87% |
| Total 4 or 17 | 3 of 216 | 50:1 to 60:1 | 15.3% to 29.2% |
| Total 7 or 14 | 15 of 216 | 12:1 | 9.72% |
| Total 10 or 11 | 27 of 216 | 6:1 | 12.5% |
| Any triple | 6 of 216 | 24:1 to 30:1 | 13.9% to 30.6% |
| Specific triple | 1 of 216 | 150:1 to 180:1 | 16.2% to 30.1% |
| Two-dice combination | 30 of 216 | 5:1 | 16.7% |
Payout schedules vary by casino and by table. Edges shown are calculated for the payouts listed; always read the layout before betting.
The pattern is clear: the simplest even-money bets are the cheapest to play, and the eye-catching long shots are the most expensive. None of these edges can be overcome by a betting system.
