The term House Edge refers to the mathematical advantage that a casino or gambling establishment has over players in any given game. It’s expressed as a percentage of each bet that the casino expects to retain in the long run. Here’s a breakdown:
Key Points:
Built-in Advantage:
It ensures that casinos profit over time, regardless of short-term player wins.
Calculation:
The house edge is calculated as:
House Edge =(Casino’s Expected Profit /Player’s Original Bet)×100 %
Example: In European Roulette, the house edge is ~2.7% because of the single “0” pocket.
Game-Specific:
Blackjack: ~0.5–2% (varies with rules/strategy)
American Roulette: ~5.26% (due to “0” and “00”)
Slots: 2–15% (varies by machine)
Craps: ~1.4% (on pass-line bets)
Why It Matters:
Players lose money faster with a higher house edge.
It helps players choose games with better odds (e.g., blackjack over slots).
Example:
If you bet $100 on a game with a 5% house edge:
The casino expects to keep $5 of your bet long-term.
You’re statistically likely to lose $5 per $100 wagered over time.
Note:
⚠️ The house edge is a long-term statistical average. In the short term, players can win big due to luck, but the edge ensures the casino always profits over thousands of bets.
