Bettors are often on the lookout for the best payout casino, but it can be tricky to work out which operators are running their games at the maximum payout level and which have reduced the potential for a big win.
asserted
which → work → win
By using the return-to-player - or RTP - metric, bettors can work out the best payout casinos available in the UK.
But it can be time-consuming to check RTP figures, so The Standard’s gambling team have done the legwork for you.

We’ve compared online casinos that publish their genuine RTP figures to work out which is the top payout casino in 2026.
asserted
which → compare → 2026
Return to Player, commonly shortened to RTP, is the percentage of every pound staked on a casino game that is statistically designed to pay back to players over millions of spins or hands.
asserted
that → shorten → spins
So, a 96% RTP slot returns - on average - £96 in winnings for every £100 wagered over the long run.
asserted
slot → return → run
The remaining £4 represents the casino’s profit, often called the 'house edge'.
asserted
4 → remain → profit
It is important to keep in mind that RTP is just a long-term statistical average - it does not mean that any individual session will result in the same return as the RTP percentage.
asserted
session → keep → percentage
For example, a player could lose every spin on a 99% RTP slot in a 10-spin run, or hit a big win on a 90% RTP slot with their first spin.
uncertain
player → lose → spin
Across the industry, most of the best online slots are set between 94%-97%, while table games are typically set at 98-99% if they are played optimally.
asserted
they → set → %
Similarly, RTP for video poker rises to 99.5% with the best strategy.
asserted
RTP → rise → strategy
Standard European Roulette has an average RTP of 97.30%, and standard American Roulette is slightly lower at 94.74% RTP.
asserted
Roulette → have → RTP
What does 'best payout casino' mean?
asserted
casino → mean → What
The best payout casino is a site where the numbers are most in the player's favour - in other words, the best potential return when gambling, measured by RTP.
asserted
numbers → gamble → RTP
Other factors such as withdrawal speeds and potential bonuses are not considered when ranking the top payout casino, but will be pointed out to readers.
The Standard’s betting experts have based their reviews on two factors - the RTP figures published by the casino that tell the player what return to expect, plus the selection of high-RTP games across slots, table games and video poker, meaning that the player has a wealth of options with potentially higher returns.
Just because a site has a high RTP or is labelled as a best payout casino does not mean each session will be profitable.
asserted
session → consider → casino
It simply means that the long-run maths on certain games are more favourable to the player than at lower-RTP sites.
asserted
maths → mean → sites
Casinos exist to make money, meaning the house always profits over the long term.
asserted
house → exist → term
All the online casinos listed are licensed with the United Kingdom Gambling Commission (UKGC) and compliant with the January 2026 wagering and bonus rules, which banned mixed casino-and-sportsbook welcome offers and wagering requirements above 10x.

Mr Vegas
Mr Vegas’s library specifically flags a 'strong selection' of high-RTP slots for value-seeking players, and I also appreciate the fact that they have a ‘game payouts’ section of the website that updates to show any changes to RTP percentages for all their games.
asserted
that → wager → games
The Mr Vegas welcome offer is a 100 per cent deposit match up to £50 plus 11 no-wagering free spins for use on Pink Elephants 2.

asserted
which → give → games
Click into a game itself on Virgin and you’ll find a detailed breakdown of how the game works, what the different bonuses entail and betting limits.
asserted

One key aspect missing from those game breakdowns is the RTP for each game, something I’d like to see added by Virgin Games in the future.
asserted
I → miss → future
Virgin does provide a good selection of high RTP slot games, including the likes of Money Cart 2 (98%) and Immortal Romance (96.86%), while players can jump across to the online casino or live casino to play higher RTP table games like blackjack or roulette.
asserted

Disappointingly, I found the promotions tab to be effectively empty during testing.
