What is House Edge?
The house edge is a fundamental concept in gambling that can significantly impact a player's overall experience and potential for winning. It represents the mathematical advantage that casinos or gambling establishments hold over players in any given game. This edge ensures that, over time, the casino will generate revenue and profit, even if individual players experience wins in the short term. Understanding the house edge is crucial for players to make informed decisions, manage their expectations responsibly, and engage in gambling with a clear understanding of the odds involved.
Games with the Lowest House Edge
While all casino games have a built-in house edge, some offer more favorable odds for players. These games typically have a lower house edge, increasing the potential for players to win more often or minimize their losses over time. For instance, Blackjack (Single Deck) offers odds as low as 0.5%–1%, while Craps (Pass/Don't Pass) comes in at about 1.40%. In Baccarat, a well-placed Banker Bet provides an edge around 1.17%. Video Poker (Jacks or Better) can even drop to 0.46%–0.75%, with European and French Roulette offering 2.70% and 1.35% (with the La Partage rule) respectively.
In Blackjack, skill and strategy help reduce the casino's advantage. Similarly, in Craps, players can enhance their odds with "odds bets" that carry no house edge. These examples demonstrate why many players seek games with the lowest house edge.
How Does the House Edge Work?
The house edge is built into the rules and payouts of each game—it’s calculated as a percentage of the player's original bet that the casino expects to keep over time. For example, in a game with a 5% house edge, the casino expects to retain €5 for every €100 wagered on average.
Consider a simple coin toss game: you bet €10 on heads; if the coin lands on heads, you win €10 (getting your bet back), but if it lands on tails, you lose your bet entirely. Even with a 50/50 chance, the casino benefits by keeping the wager on losses. This principle extends to sports betting—often called "vigorish" or "juice"—and to poker where a "rake" is taken from each pot.
For example, a sportsbook may offer odds of 1.90, but the "fair" odds might be closer to 1.85, subtly embedding the house edge into the wager.
In poker, the house secures profit through the rake regardless of which player wins. This built‑in edge is what ensures the casino’s long‑term profitability.
House Edge in Different Casino Games
The house edge varies widely across casino games. For example, in Blackjack (basic strategy), the edge ranges between 0.5%–2%, whereas Baccarat (Banker bet) is around 1.06%. In Craps (Pass Line bet) it is approximately 1.41%, with European Roulette at 2.70% and American Roulette at 5.26%. Slot machines can range from 2% to 15%, and Keno is notably high at 25%–29%.
Notably, European Roulette is favored over American Roulette due to its single zero, which significantly improves the odds. This difference in configuration makes European Roulette more attractive for players looking to minimize the house edge.
