Sic Bo and Keno Explained: The Two Games Worth Knowing — and Usually Skipping
Sic Bo and Keno are among the highest house-edge games in any casino. Here is how each game works, what the numbers actually mean, and an honest case for why most players should treat them as curiosities rather than strategies.
Sic Bo and Keno occupy a specific niche in the casino ecosystem: they are games that most players have heard of, a minority actually play, and almost nobody fully understands before sitting down. That information gap tends to be expensive.

What Sic Bo Is
Sic Bo (骰寶, “precious dice”) is a Chinese dice game found in Macau-style casinos, many Southeast Asian venues, and increasingly in live-dealer sections of online casinos. Three dice are shaken in a covered container; the dealer reveals the result; players who bet correctly on the outcome are paid. That is the entirety of the gameplay — no decisions after the bet, no drawing rules, no strategy layer.
The complexity lives entirely in the betting layout, which looks overwhelming at first glance. A standard Sic Bo table offers somewhere between fifteen and twenty distinct bet types, each with its own payout and house edge.
Sic Bo Bet Types and What They Actually Cost
| Bet | Wins When | Payout | House Edge |
|---|---|---|---|
| Small | Total 4–10 (no triple) | 1:1 | ~2.78% |
| Big | Total 11–17 (no triple) | 1:1 | ~2.78% |
| Specific Triple | All three dice show one number | 180:1 | ~16.2% |
| Any Triple | All three dice match (any number) | 30:1 | ~13.9% |
| Specific Double | Two dice show a specific number | 10:1 | ~18.5% |
| Two-Dice Combination | Two specific numbers appear | 6:1 | ~16.7% |
| Total (e.g. 9 or 12) | Sum equals that number | Varies (6:1 to 60:1) | ~12–19% |
| Single Number | One die shows that number | 1:1 / 2:1 / 3:1 | ~7.9% |
The small and big bets are the only wagers on the board that sit in defensible territory. A small bet wins when the three-dice total falls between 4 and 10, excluding any triple; big wins on 11 through 17, with the same triple exclusion. At ~2.78%, both bets carry roughly the same house edge as the double-zero slot on an American roulette wheel — not great, but far more honest than what the rest of the table offers.
Everything else degrades quickly. Specific triples pay 180:1 and look like the high-variance jackpot that might justify the risk. They are not. The true probability of a specific triple is 1-in-216; at 180:1, you are giving up 35 outcomes’ worth of value on every spin. The house keeps 16 cents of every dollar wagered on this bet, on average.
The two-dice combination bets are similarly instructive. There are fifteen possible two-die combinations across three dice; the probability of hitting any given combination is 15/216, or roughly 6.9%. A 6:1 payout on a 6.9% event produces a house edge around 16.7%. The casino has built the illusion of complexity — a crowded table with dozens of betting options — to obscure the fact that only a small corner of it is mathematically reasonable.
What Keno Is
Keno is a lottery-style game. The player selects between 1 and 20 numbers from a field of 80; the casino (or RNG) draws 20 numbers at random; the payout depends on how many of the player’s picks match the drawn numbers. In live casino settings, draws happen every few minutes. Online, they run as fast as you choose to play.
There is no strategy. Every number in the pool has an equal probability of being drawn on every game — 20 out of 80, or 25%. Past results carry no information about future draws. Hot and cold number trackers, pattern systems, and “due” numbers are noise.
What does exist is structural variation in payout tables. Different operators offer different pay tables, and the house edge varies accordingly — typically between 20% and 35% in brick-and-mortar settings, with some online variants running closer to 15%. The number of spots you select also affects the distribution of outcomes: picking more numbers makes large wins possible but also makes it easier to win very little, creating a wide variance profile that feels more exciting than it mathematically justifies.
Why the House Edge Is So High
Both Sic Bo (for most bets) and Keno share a structural characteristic: they were designed for players who prefer simplicity and speed over optimised odds. The randomness is genuine — there is no dealer skill in Sic Bo, and Keno’s RNG can be audited for fairness. The issue is not fraud; it is the payout structure.
In games like blackjack or baccarat, the house edge is achieved by modifying payouts very slightly from true probability — often a fraction of a percent per hand. In Keno and many Sic Bo bets, the house retains its edge by offering payouts that are dramatically below the true odds. A specific triple paying 180:1 when the true odds are 215:1 is not subtle.
This is not unique to these games. The house edge on American roulette’s straight-up single-number bet is 5.26% — better than most Sic Bo props, though still higher than blackjack. The important difference is that Keno’s edge operates over a game that repeats very quickly and offers almost no variance offset through skill. In Sic Bo, at least, bet selection meaningfully changes your exposure.
Should You Play?
The honest answer is that most players should not choose Sic Bo or Keno as their primary casino games if they care about odds. But “caring about odds” is not everyone’s reason for playing.
Sic Bo, limited to small/big bets, is a reasonable choice for players who want a dice game with a lower house edge than most of what surrounds it. The pace is slow, the rules require minimal learning, and the small/big bet is transparently fair. If you are at a live-dealer table and enjoy the social format, this is a defensible way to spend time.
Keno is harder to justify on mathematical grounds alone. A 20–35% house edge means that in the long run, you are losing two to three times faster per dollar wagered than on roulette — which itself is rarely recommended by anyone who has run the numbers. Keno’s appeal is the lottery-ticket psychology: small stakes, rare but large wins, and an almost-TV-lottery aesthetic. That appeal is real; the math is not in your favour.
Where to Play Online
If you are going to play either game, provably fair variants at a well-licensed operator are the sensible baseline. See our guide to provably fair vs RNG games for how to verify that the randomness is genuine.

Responsible Gambling
Both Sic Bo and Keno are legal in some jurisdictions and not others. This is not legal advice — confirm whether online gambling is permitted in your country of residence before playing. You must be 18 or older (or the legal minimum age in your jurisdiction).
Keno’s high house edge and fast pace make it a meaningful bankroll-depletion risk. If you choose to play, set a session budget before you start and do not chase losses. For tools that help manage gambling exposure — deposit caps, cool-off periods, self-exclusion — see our guide to responsible gambling tools. Free confidential support is available from BeGambleAware (UK) and the National Problem Gambling Helpline (US, 1-800-522-4700).
Bottom line: Sic Bo is a game with a wide range of house edges — some defensible, most not. Keno is a game where the house always wins a large fraction of every wager, at speed, with no mechanism for the player to reduce that fraction. Knowing this does not mean you cannot play either; it means you walk in with accurate expectations. That is what the math is for.
FAQ
- What is the house edge in Sic Bo?
- It depends entirely on which bet you choose. The small/big bets carry roughly 2.78% house edge — the most defensible options on the table. Triple bets (a specific triple) sit at around 16%. Many of the flashier combinations land between 8% and 18%. The table is not uniformly bad, but the bad bets are very bad.
- What is the house edge in Keno?
- Keno house edges typically range from 20% to 35%, depending on the operator's pay table. Some online versions run lower, around 15%, but the game is fundamentally designed as slow-burn entertainment rather than a low-cost wager. No strategy reduces the edge — the only variable is how quickly you want to deplete your bankroll.
- Is there any strategy for Sic Bo or Keno?
- For Sic Bo, bet selection matters: sticking to the small or big bets minimises the house edge significantly. For Keno, there is no strategy — the draw is random and every number is equally likely. Picking 'hot numbers' or patterns does not affect outcomes. The only choice is how many numbers to select, which changes the payout structure but not the underlying house edge.
