If a casino paid out $1 for every $1 bet on a correct guess, it would have no edge. The house edge is derived from the gap between the true odds of an outcome and the payout odds offered by the casino. Every casino game is designed with a similar, albeit more complex, mathematical imbalance that benefits the house. For example, in a coin toss, the true odds of heads are 1-to-1. But if it only paid out $0.95 for casino every $1 bet, that 5-cent difference would be its edge.

For every possible combination of your hand and the dealer's upcard, there is one mathematically optimal decision (hit, stand, double, or split) that will result in the highest expected return over the long run. While memorizing the entire chart can seem daunting, learning a few key rules can dramatically improve your game:

Blackjack
0.5% - 2%
Player skill and strategy are paramount. Roulette (European)

The single zero (0) on the wheel cuts the house edge in half compared to its American counterpart, making it a much better choice for players. Following basic strategy can lower the edge to ~0.5%. Craps
Varies
The edge varies wildly depending on the bet. "Proposition" bets can have an edge of over 16%. A 95% RTP means a 5% house edge. This is not disclosed on the machine itself in most land-based casinos. Simple bets like the Pass/Don't Pass line have a low edge. Roulette (American)
High
The presence of two zeros (0 and 00) on the wheel significantly increases the house advantage compared to European Roulette. Slots
2% - 15%
Each machine is programmed with a specific Return to Player (RTP). Baccarat (Banker Bet)
Very Low
The Banker bet has one of the lowest house edges in the casino, even after accounting for the 5% commission on wins.
