Casino games with the best odds

A casino bet carries a price. The house edge is that price. You can work out how much of each £10 stake the operator keeps over thousands of rounds. You cannot remove the edge. You can choose a game where you lose money at a slower rate, and you can skip the bets with the highest cost.

The price of a bet

House edge is the gap between the true odds of an outcome and the payout a casino offers. On a roulette bet with a 2.7% edge, the casino keeps £2.70 from every £100 staked across a long sample. You can win or lose far from that figure in one session. You still see the average when you add up thousands of spins, hands, or rolls.

UKGC-licensed casinos operate under the Gambling Act 2005. That licence requires clear game rules, published RTP for slots, and fair terms on bonuses. The regulator does not set a single house edge for each game. Operators choose their table rules and slot designs, and those choices change the price you pay.

RTP measures a long sample

Return to player is the share of stakes a game returns over millions of spins. A 96% RTP slot returns £96 for every £100 staked in that sample. The casino keeps £4. You can use the figure to compare two slot games with similar volatility. You learn little about the shape of the game from that figure.

You can find UK slot RTP anywhere from the low 90s to 97%. You may see a two-point gap as small in the lobby. Over £1,000 of spins, you face an expected loss of £40 on the 94% game and £60 on the 92% game. Check the information tab before you spin. You may find a different RTP at another casino.

Baccarat: banker and player

Baccarat gives you a clean comparison. You face a house edge around 1.06% on the banker bet with a standard eight-deck shoe. You face a house edge near 1.24% on the player bet. You pay far more on the tie bet, which carries a house edge above 14%. Stick to banker or player and leave the tie alone.

The casino pays a bit less than even money on the banker bet because it takes a commission. The casino takes that commission on banker wins. In return, you face a lower edge on the banker bet than on the player bet. Do not let the 5% commission put you off. You still get some of the best odds on the casino floor from the banker bet. Check the table rules for the commission rate and the number of decks before you sit down.

Blackjack: learn the chart

Blackjack rewards you when you learn basic strategy. You can face a house edge below 1% when you follow the correct play for each hand. That means memorising when to hit, stand, double, or split. You lose about 7p on a £10 hand at 0.7% over a long sample. You lose about 27p on the same £10 at a 2.7% roulette bet over a long sample.

You get a better chance at a blackjack table that pays 3:2 on a natural than at one that pays 6:5. A dealer who stands on soft 17 gives you a better chance than a dealer who hits soft 17. Read the felt or the game info panel. You face a different edge under a different rule set.

Roulette: one wheel changes everything

You see one zero on a European roulette wheel. With one zero, the casino holds a 2.7% edge on most outside bets. You see a double zero on an American roulette wheel, and the casino holds a bigger edge because of the extra pocket. If you want the best odds at roulette, play the single-zero table. Avoid the American wheel unless you enjoy paying for the extra pocket.

You get bigger payouts on inside bets and you face the same edge on a single-zero wheel. The casino pays 35:1 on a straight-up number, and the true odds are 36:1. The casino keeps the difference to cover the zero. You can spread chips across the table, but you face a 2.7% edge on each bet. You face a different edge on a single-zero wheel and an American wheel. You change the payout and the swing when you spread your chips in a different pattern.

Slots: RTP plus volatility

Operators publish RTP for each slot. You learn little about the shape of the game from that figure. On a 96% slot with high volatility, you can go a long time before you see a return close to that figure. You get small, frequent wins on a 96% slot with low volatility. The casino keeps 4p per £1 over the long sample on both games. You choose based on how much swing you can take.

You face the same house edge across volatility levels. You see more frequent wins on a low-volatility slot and longer dry spells on a high-volatility slot. Choose a high-volatility slot if you want a shot at a large win and can accept long runs without a payout. Choose a low-volatility slot if you want more frequent returns and a steadier bankroll. Check the RTP and the volatility rating before you pick a game. You still face risk on a high RTP slot with high volatility.

Sic bo and casino hold'em

You can find a wide range of odds on a sic bo table. The casino holds an edge around 2.8% on the small and big bets. You pay far more on specific triples. When you know Casino Hold'em, you face a house edge near 2.2% on the ante bet, yet the casino can hold a much larger margin on the side bet. You will see the same pattern across the casino floor: you often get the best chance from the simple bet with the lowest payout.

Read the bet slip before you place a chip. The casino can hold a double-digit edge on a side bet with a big headline payout. You get better value from the main bet in most cases. You can apply that rule to blackjack side bets, roulette call bets, and the extra wagers on casino hold'em. If you cannot find the house edge in the rules, assume the side bet is expensive.

The £100 test

Put £100 into a game with a 1% house edge and you face an expected loss of £1 across a long sample. Put the same £100 into a game with a 10% edge and you face an expected loss of £10. You can win or lose in one session. You can see the average over thousands of bets, and the casino relies on that average.

Use that test to compare games with the same stake. You face a smaller expected loss with a £100 bankroll on baccarat banker than with the same £100 on a high-edge slot. You also see fewer swings per hour. You need to weigh time as much as the edge. You can lose more per hour on a low-edge game with 200 hands than on a higher-edge game with 20 bets.

Where to check the numbers

UKGC-licensed casinos publish game rules and RTP for slots. You can read the number of decks, the wheel type, and the side bets in the table game rules. Read those pages before you stake. You see a 96% slot and a 94% slot as the same in the lobby. You can find the difference in the information tab.

When you compare tables at a UKGC-licensed site like Midarion Casino, open the game info panel first and check the RTP, the deck count, and the table limits. You get little from a low house edge if you lose your bankroll in ten hands at the minimum stake. Set a stake that lets you play enough rounds to see the average.

You face the same house edge with a debit card deposit or a PayPal balance. Credit cards cannot fund a UK gambling deposit, and you cannot change the maths of the game with a payment method. You decide how long you stay in the chair when you set a bankroll plan.

Set limits before you play

Set a deposit limit before you open a table. Use GamStop if you need to block access to UK-licensed sites, and read BeGambleAware's guidance if your spending feels hard to control. You still face risk on a game with a low house edge. You still face the house edge. You set the limit before you play, and you stop when you reach it.
