House Edge by Game: The Numbers That Matter
Every casino game carries a built-in mathematical advantage for the house. That advantage, expressed as a percentage of every wager you place, is the single most useful figure for comparing games. The chart below breaks down typical house edges across the games most Canadian players encounter, whether at a land-based venue in Ontario or through an online operator.

| Game | Typical House Edge | Best Strategy Available | Skill Dependent? |
|---|---|---|---|
| Blackjack (basic strategy) | 0.5% – 1.5% | Yes | Yes |
| Baccarat (banker bet) | 1.06% | Limited | No |
| Craps (pass/don’t pass) | 1.36% – 1.41% | Yes | Yes |
| Roulette (European) | 2.70% | None | No |
| Roulette (American, double zero) | 5.26% | None | No |
| Keno | 20% – 40% | None | No |
| Slots (typical online) | 2% – 10% | None | No |
The spread is dramatic. A single blackjack hand played with basic strategy costs you roughly 50 cents per $100 wagered over time. That same $100 through keno could quietly hand the house 40 dollars. Slots sit in the middle, with return-to-player (RTP) percentages typically published in the game rules and ranging from 90% to 98% at reputable online casinos operating under iGaming Ontario oversight.
American roulette deserves special mention. The extra double-zero pocket on the wheel nearly doubles the house edge compared to European roulette. Canadian players who see both variants side by side should default to single zero without hesitation.
Reading the Chart: Context and Caveats
House edge is a long-run figure. It describes what happens across thousands of bets, not what happens in your session tonight. Short-term variance can swing results in either direction, which is why a player can walk away from a 1.41% edge game with nothing and another can turn a 5.26% edge game into a profit. Understanding this distinction separates realistic expectations from wishful thinking.
Volatility matters alongside edge. Slots with high volatility pay less often but in larger bursts, while low-volatility slots pay smaller amounts more frequently. Neither changes the long-term house edge, but both change how the experience feels session to session. Table games with low edges tend to produce steadier bankroll movement, which appeals to players who want their entertainment budget to last an evening rather than twenty minutes.
Payout structures also shift effective odds. A blackjack hand paying 6:5 instead of the traditional 3:2 raises the house edge by roughly 1.4 percentage points. Always confirm the payout ratio before sitting down. On the craps table, odds bets behind the pass line carry zero house edge entirely, one of the rare instances where a casino offers a mathematically fair wager.
For Canadian players comparing operators, published RTP audits from independent testing labs such as eCOGRA provide verified numbers rather than marketing claims. Slots displaying a 96% RTP are giving back 96 cents of every dollar wagered over time. That 4-cent difference is the house edge. Multiply it across millions of spins and the business model becomes clear.
No chart eliminates risk. What it does is let you choose where your entertainment dollars go with actual information instead of instinct. Games with lower edges stretch a budget further, and knowing the difference between a 1% and a 5% edge is the most practical edge a player can bring to the table.
