Which Casino Games Have the Best Odds? Ranked by House Edge

Not all casino games give the house the same advantage. The house edge — the percentage of each bet the casino expects to keep over the long run — varies enormously between games. Understanding it means you can choose where to play with your eyes open. This guide ranks every major casino game from the best odds to the worst.

What Is the House Edge?

The house edge is the mathematical advantage the casino holds on every bet, expressed as a percentage. On a game with a 2% house edge, the casino expects to keep £2 for every £100 wagered over a large enough sample. Individual sessions vary wildly — you can win or lose far more in the short term — but over millions of hands and spins, the house edge is the governing number.

A lower house edge means your money lasts longer and your odds of walking away a winner are higher.

The Best Games to Play

Blackjack is the gold standard. With basic strategy, the house edge drops to approximately 0.5% — which means over a long session, you lose about 50p per £100 staked in expected terms. No other game comes close for an informed player. The key phrase is "basic strategy" — playing without it pushes the edge toward 2–4%.

Video Poker (full-pay Jacks or Better) technically has an even lower house edge, but it requires memorising the correct play for every hand and finding a full-pay paytable, which is harder in UK online casinos than it used to be.

Baccarat is the easiest game with good odds. Always bet banker, ignore the tie bet (which carries a house edge of around 14%), and you're playing one of the most player-friendly table games in the casino.

European Roulette is a reasonable option at 2.7%, but make sure you're playing the single-zero version. American roulette's double zero pushes the house edge almost to 5.3% — nearly twice as bad for the same game.

Games to Approach with Caution

Slots have RTPs published by UK casinos (required under UKGC rules), and many hover around 94%–96%, meaning a house edge of 4%–6%. That's not terrible, but the high volatility and speed of play mean your hourly expected loss is often higher than at a slower table game. Slots are excellent entertainment but not where you find the best odds.

American Roulette should be avoided entirely if European Roulette is available. There's no reason to accept a 5.26% house edge when 2.7% is on offer at the same site.

Keno and scratch-style instant games often carry house edges of 20–40%. They're fun for a minute but dramatically unfavourable.

How Speed of Play Affects Your Expected Loss

House edge alone doesn't tell the whole story. You also need to factor in how fast the game runs.

A slot game at £1 per spin running 10 spins a minute generates far more expected loss than a blackjack table at the same stake, even with a better RTP. Slower games with lower house edges give you the best value for your time and money.

Bottom Line

If you want the best odds, play blackjack with basic strategy or bet banker at baccarat. European roulette is a reasonable middle ground. Avoid American roulette, high-edge table variants, and treat slots as entertainment rather than a route to long-term profit. Knowing the house edge doesn't guarantee you'll win — but it guarantees you're making informed decisions about where your money goes.
