Casino strategy · House edge
Every casino game has a built-in advantage for the house. Knowing how big it is tells you which games and bets give you the best value. This guide from DBB66 Casino explains the house edge simply and ranks popular games from best to worst odds.
Key takeaways
The house edge is the percentage of every bet that a casino expects to keep in the long run. If a game has a 2% house edge, then for every RM 100 wagered over thousands of bets, the casino expects to keep RM 2 on average. For slots, the same idea is expressed as RTP: a 96% RTP slot has a 4% house edge.
The edge comes from the game rules. In roulette, it comes from the zero pockets; in baccarat, from the Banker commission; in blackjack, from the fact that players bust first.
The house edge describes the long run. In a single session, anything can happen – you can win big or lose more than the edge suggests. What the edge tells you is how quickly your money is expected to shrink while you play:
Expected loss = total amount wagered × house edge.
If you place 200 bets of RM 10 (RM 2,000 wagered) on a game with a 2.7% edge, your expected loss is about RM 54. On a 1% game it would be RM 20.
| Game and bet | House edge (approx.) |
|---|---|
| Blackjack with basic strategy (3:2) | 0.5% |
| Baccarat – Banker | 1.06% |
| Baccarat – Player | 1.24% |
| French roulette even-money (La Partage) | 1.35% |
| European roulette | 2.70% |
| Sic bo – Big / Small | 2.78% |
| Slots (96–97% RTP) | 3–4% |
| Dragon tiger – Dragon / Tiger | 3.7% |
| American roulette | 5.26% |
| Live game shows | Often 4–8% |
| Baccarat – Tie (8:1) | 14.4% |
| Keno and long-shot bets | Often 20%+ |
No casino game offers positive long-term odds, but some are much better than others:
Many players lose more than necessary by choosing the worst bets inside good games:
Avoiding these "holes" is the easiest way to improve your odds without changing games.
House edge tells you the average cost; volatility tells you how wildly results swing. A game can have a low edge and high volatility (some blackjack side bets) or a higher edge and low volatility (some classic slots). Choose the edge first, then the volatility you enjoy.
Rebates return a percentage of your turnover, and deposit bonuses add playing money. Both can reduce the effective house edge if the terms are fair. Check our promotions page and always read turnover requirements, game weightings and maximum bet rules.
Bottom line: play the games and bets with the smallest house edge, avoid side bets, and remember that low edge means longer play, not guaranteed profit.
The average percentage of each bet the casino keeps in the long run. A 2% edge means RM 2 per RM 100 wagered on average.
Blackjack with basic strategy, at around 0.5%, followed by baccarat Banker at about 1.06%.
Not in the long run with standard games. You can reduce it with good strategy and fair promotions.
Tie bets, insurance, most side bets, American roulette and 6:5 blackjack.
