What are payout rates? RTP & house edge explained
Casino payout rates, also known as return-to-player (RTP) percentages or win rates, show the average amount a game or a casino pays back over time, rather than in a single session, compared to the money wagered. They are always expressed as a percentage.
Return To Player (RTP)
RTP is the percentage of all money wagered that a game is designed to pay back to players over the long term. For example, if a slot has an RTP of 96%, it is expected to return £96 for every £100 wagered over time. Remember, RTP is measured across thousands or even millions of bets by different players, not your individual session.House edge
House edge is the opposite of RTP. While RTP shows what a game pays back to players over time, house edge shows what the casino keeps. For example, a 4% house edge means the casino is expected to keep £4 for every £100 wagered over the long run.
Improve your chances of bonus returns with high-RTP games
When you use bonus cash from promotions featured on our list of the best UK casino offers, check the T&Cs to see how much certain games contribute to the wagering requirements. For example, some UK sites might offer high-RTP slots such as Jokerizer (99% RTP), but not allow bets to count towards wagering. Table games are also often blocked or only contribute around 5-10%. However, the RTP rates of eligible games vary. To give yourself the best chance of preserving your bonus balance while clearing the wagering requirements, stick to high-RTP games that count 100% towards wagering.Fast withdrawal casinos with high payout rates

Latest payout test: 1429 Uncharted Seas
📝Tested by Ben Perks | UK Content Editor
"I decided to test one of my all-time high-payout favourites this month: 1429 Uncharted Seas. This slot has a 98.5% RTP and is available at Casumo - where I played it. From a total spend of £5, I cashed out £7.30, resulting in a £2.30 win. Yet this is the sixth time I've played this game, but the first time I've walked away without making a loss."
1429 Uncharted Seas: Game info
1429 Uncharted Seas is a high-payout slot from Thunderkick. Trigger the free spins bonus by landing three or more scatter symbols, where expanding wilds and multipliers can combine for bigger wins.How we rate high payout casinos
Along with considering a site’s overall payout rate, we test the site using Casino.org’s 25-step review process. We look at game choice, withdrawal speed, bonus terms, and the overall user experience. Scroll down to learn how and why we assess these key areas.✔️ Overall payout rate
To discover the best payout casinos, our team analyses the RTPs across each site’s game library to calculate its overall win rate and identify UK-licensed operators that sit above the 96% industry average.✔️ Variety of high RTP games
We assess how many high RTP games each site offers across slots, roulette, blackjack, baccarat, etc., to ensure you have plenty of options. Casumo’s 98.37% payout rate is especially impressive, as it is averaged across a varied library of 4,400+ games - one of the largest in the UK.✔️ Fairness of games
Sites that work with third-party auditors such as eCOGRA rate them more highly, as this helps verify that RTP figures are accurate, games are fair, and random number generators (RNGs) - the systems that keep game outcomes random - work as they should.✔️ Withdrawal speeds and number of payment options
We test how easy it is to cash out, how many payment methods a site supports, and how quickly withdrawals land - any casino that takes longer than a week does not make the cut. Based on our latest tests, Casumo is the fastest, with withdrawals taking under 2 hours.✔️ Bonuses valid for high payout games
If a casino restricts bonus wagering to games with RTPs below 96%, it gets a lower score. Sites like Betway score more highly because they offer no-wager bonuses on high RTP games. Its 150 free spins promo, for instance, can be used on five different high-payout slots, such as Gold Blitz Ultimate (96.5% RTP).😊 Overall experience
From how easy the sign-up process is to mobile compatibility, customer support, and the standard of the games, we weigh up the full gambling experience. If a site falls short in any key area, it won't make our top 10.Expert tips to maximise your winnings
Remember, even sites with high overall win rates don’t guarantee wins; that’s why I have some expert tips to keep you on the right track.
Double check the RTP of games
Be aware that different RTP versions of certain casino games exist. For example, Dead or Alive 3 Wanted comes with one of the following three payout rates: 96.03% RTP, 94.02% RTP, or 92.08% RTP. Therefore, always check the paytable by tapping the information icon (i) featured on the game menu before playing for real money.Use the right strategy when playing table games
The RTP of table games often depends on how you play. In blackjack, the advertised RTP is based on basic strategy - the mathematically best way to play every hand based on your cards and the dealer’s visible card. It tells you when to hit, stand, double down, or split to give you the highest possible RTP. If you follow basic strategy closely, blackjack’s RTP is around 99.6%.Check volatility
Check a game’s volatility because it helps you pick titles that match how you want to play. Lower volatility games usually pay smaller amounts more often, which can help your bankroll last longer. High volatility games, however, are the opposite: they pay less often, but individual wins will be bigger than those of low volatility titles.Always play responsibly
Playing high RTP games does not guarantee you will win. At Casino.org, safe and responsible play comes first. Keep these responsible gambling tips in mind:
- Never treat gambling as a source of income
- Set budget and playtime limits - all the casinos we recommend on this page have built-in spending and time tracking tools
- Don't chase losses
