Every casino table game includes a mathematical advantage for the house, but knowing how this works can help players understand their odds.
When exploring online casino table games, you may notice that each game favours the house by a certain percentage. This built-in advantage is known as the house edge, and understanding it helps players make informed decisions about which games to play and what to expect over time.
The house edge represents the mathematical advantage a casino holds over players in any given game. Expressed as a percentage, it indicates how much of each wager the casino expects to retain on average over the long term. For instance, a house edge of two percent means that for every £100 wagered, the casino anticipates keeping £2 statistically.
Different table games carry different house edges. Blackjack, when played with basic strategy, typically offers one of the lowest edges, often below one percent. Baccarat sits around 1.06 percent on banker bets. Roulette varies significantly depending on the variant—European roulette has a 2.7 percent edge, whilst American roulette reaches 5.26 percent due to the additional double zero.
The house edge does not guarantee losses on every session, but it does indicate expected outcomes over thousands of hands or spins. Short-term results can vary widely due to variance, meaning players may win or lose more than the edge suggests in any single sitting. However, the longer someone plays, the closer their actual results tend to align with the mathematical expectation.
Return to Player, or RTP, is simply the inverse of the house edge. A game with a three percent house edge has a 97 percent RTP, meaning players collectively receive back £97 of every £100 wagered on average.
