Bettors always want to be playing with the best payout casino, but the sheer amount of casino sites available in the UK can make it difficult to determine the cream of the crop.

However, by using the return-to-player - or RTP - metric, bettors can work out the best payout casinos available in the UK.

Here, we compare the best online casinos that publish their genuine RTP figures and carry the deepest high return-to-player game catalogues across slots, table games and video poker.

What is RTP?

Return to Player, commonly shortened to as 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.

So, a 96% RTP slot returns - on average - £96 in winnings for every £100 wagered over the long run. The remaining £4 represents the casino’s profit, often called the 'house edge'.

It is important to keep in mind that RTP is just a long-term statistical average - it does not mean that in any individual session will result in the same return as the RTP 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.

Across the industry, most of the best online slots are typically set between 94-97%, whilst table games near 98-99% if they are played optimally. Similarly, RTP for video poker rises up to 99.5% with the best strategy.

Standard European Roulette has an average RTP of 97.30%, and standard American Roulette is slightly lower at 94.74% RTP.

What we mean by 'best payout casino'?

While the title of best overall casino can be quite subjective and dependent on wants and needs, the best payout casinos can be more easily measured by maths.

Simply, 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.

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 tells 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. It simply means that the long-run maths on certain games are more favourable to the player than at lower-RTP sites. Casinos exist to make money, meaning it is always profitable for the house over the long term.

Best payout casinos UK compared - July 2026

All the 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.

Grand Ivy Casino

Grand Ivy Casino is the only UK casino in this list that publishes a full RTP breakdown in its footer. According to the site, slots sit around 96-97% RTP, table games around 99% and virtual games around 94%. This transparency allows bettors to know exactly the state of play when using the Grand Ivy Casino.

The Grand Ivy Casino welcome bonus is 20 wager-free spins after a £10 first deposit, with winnings paid as cash but capped at £100. This does not provide as many spins as some rival casino sites, but the cash conversion is immediate and the £100 cap is real money rather than restricted bonus funds.

The slots catalogue runs to around 1,385 titles from NetEnt, Elk Studios, Quickspin and Red Tiger.

What really stands out is the depth of table games, with 29 blackjack variants and 16 roulette variants beating almost every rival on this list for high-RTP table coverage.

Ongoing promotions for existing players include the daily Bonus Wheel - a free spin awarding casino bonuses and free spins.

There’s also a £500 weekly cash giveaway where 10 random winners share the pot with no wagering attached. Unfortunately, the VIP scheme was retired in May 2026.

• Dedicated RTP page in footer covering every game on the site
• Deepest table game variety on this list (29 blackjack, 16 roulette, 12 poker variants)
• Wager-free welcome winnings paid as cash up to £100

• No instant withdrawal options
• £100 cap on free spins winnings limits the upside

Pub Casino

Pub Casino publish a 96.10% headline payout percentage from it’s large collection of 2,200+ games, including 200+ Evolution Gaming live dealer tables.

The operator’s welcome offer is 50 no-wagering free spins worth 20p each, providing a face value of £10. The Pub Casino welcome offer has no maximum win cap, although it does expire after 48-hours - quite a tight expiry window.

A big draw is the exclusive Pub Casino-branded live blackjack and roulette, but there’s also crash games such as Spaceman and Speed Crash.

Disappointingly, I found the promotions tab to be effectively empty during testing. There’s no reload offers, daily free spins or weekly cashback running, nor is there a VIP programme.

• Published 96.10% payout percentage
• No-wagering welcome bonus with no win cap
• Deep table game variety via Evolution Gaming live dealer tables

• Very little ongoing promotional activity
• Tight 48-hour free spins expiry
• Skrill excluded from welcome offer

Mr Vegas

Mr Vegas Casino’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.

The Mr Vegas Casino welcome offer is a 100% deposit match up to £50 plus 11 no-wagering free spins for use on Pink Elephants 2. Other welcome offer restrictions to bear in mind include the £10 minimum deposit, 10x wagering requirements on bonus funds from the deposit match but no wagering on the spins - although jackpot slots contribute 0% to wagering.

Mr Vegas Casino also boasts the largest library on this list with 9,600+ games from top studios including Microgaming, NetEnt and Pragmatic Play. There’s 750+ live dealer tables from Evolution, Pragmatic Play Live and Playtech, and also multi-million WowPot progressive prizes.

Mr Vegas Casino is not lacking in terms of casino bonuses - Rainbow Fridays provides a guaranteed win, with bettors awarded up to £300. The Wheel of Vegas randomly-triggered jackpot wheel has Mini, Major and Mega tiers with different prizes. In terms of negatives, I’m not a huge fan of the old-fashioned site layout - which is even more important, as there is no dedicated mobile app currently available.

• Largest game library on this list at 9,600+ titles
• Brand-flagged high-RTP slot selection
• Rainbow Fridays guaranteed weekly win up to £300

• Jackpot slots don't contribute to welcome bonus wagering
• No VIP/loyalty system

Bet365

Bet365’s RTP runs 0.30% above the industry average, with some of the most popular slot games available at their maximum RTP. Each game is also accompained by an infirmation display, showing bettors the RTP and volatility of that particular title.

Bet365 casino features 150+ progressive jackpot games across five premium networks - Age of the Gods, Jackpot King, Mega Millions, Mega Moolah, and WowPot.

On top of that there’s the exclusive Bet365-branded versions of Age of the Gods: God of Storms bet365, Gates of bet365, and Razor Returns bet365.

This is further backed up by a decent library of 3,000+ games, with 200+ live dealer tables from Evolution, Playtech Live and Pragmatic Play Live, 100+ classic RNG table games including blackjack, roulette, baccarat plus 3 Card Brag, Craps, Jacks or Better, and Hi-Lo.

The Bet365 welcome offer drip feeds up to 500 no-wagering spins across 10 days. After a £10 minimum deposit, each day will reveal between five, 10, 20, or 50 free spins for a total of 500 spins worth 10p each.

• Slot games run at above the industry average RTP
• Exclusive Bet365-branded high-RTP slots
• Five premium jackpot networks plus 100+ RNG (random number generator) table games

• No VIP programme
• Customer service slow to resolve simple queries
• Paysafecard deposits excluded from welcome offer

Ladbrokes Casino

The Ladbrokes casino undergoes RTP audits by the independent group Gaming Laboratories International, who found the RTP to be at the highest possible setting on nine of the 10 slots they tracked.

Ladbrokes’ welcome offer gives new users 100 no-wagering free spins worth 10p each, as well as 300 LadBucks that are redeemable in the LadBucks Arcade. Players have seven days to use the free spins across a 12-game eligible pool, the broadest on this list. However, it must be pointed out that deposits from e-wallets such as Neteller, PayPal, Paysafecard and Skrill are excluded.

Only Betfred can match the depth of 200+ progressive jackpot slots Ladbrokes can boast. The operator has 50+ exclusive Ladbrokes-branded titles, including Big Banker, Lock O' The Irish, and Well, Well, Well.

Overall there are over 5,700 casino games on Ladbrokes, with 600+ live dealer tables across providers such as Evolution, Playtech Live and Pragmatic Play Live.

There’s also a broad range of RNG table games including blackjack and roulette variants, Craps, Heads-Up Poker, Hi-Lo, and Jacks or Better.

Ongoing promotions from Ladbrokes include the Instant Spins Daily Free Game and the Instant Rewards monthly giveaway of cash and free spins.

• 12-game eligible pool on the no-wagering welcome - most flexible on this list
• RTP audit found most games running at maximum RTP
• Very deep library (5,700+) compared to rivals

• Welcome bonus excludes Neteller, PayPal, Paysafecard and Skrill deposits
• Cluttered site navigation makes large library hard to browse

LeoVegas Casino

Although LeoVegas Casino may not offer as many premium progressive jackpot slots as others on this list, the fact that their 60+ selection covers all six major networks - Age of the Gods, Jackpot King, King Millions, LotsaLoot, Mega Moolah, and WowPot - is a huge selling factor.

There’s also the LeoVegas-branded exclusive slots - Gates of LeoVegas 1000, LeoVegas Cluster Gems, and LeoVegas Megaways - in a library filled with over

LeoVegas’s library of 4,000+ games is the second-deepest on this list but each game is accompanied by a small summary, including game type, pay mechanic and, most importantly for a high payout casino, volatility.

This means bettors can work out their potential returns on a game with high volatility games providing less frequent wins, but larger payouts when they do arrive.

• All six premium progressive jackpot networks - broadest in this list
• Relatively deep casino library of 4,000+ games
• Volatility ranking displayed on each game

• Welcome offer modest at 50 free spins (£5 face value)
• Tight 72-hour free spins expiry

Betfred Casino

Betfred averages around 97% RTP across its slots and boosts select titles above the developer default, such as Blueprint's 777 Deluxe running at 95% here versus the standard 92%. The live blackjack sits at 99.50% and roulette at 98.65%, so the payout maths stack up before you've even spun.

It's also one of the few UK casinos to publish the RTP of every slot in a dedicated information section on each game page, giving players the transparency to hunt out the highest-returning titles rather than guess.

The welcome offer plays into the same value angle: up to 200 no-wagering free spins with a three-way choice, unlocked with a £10 deposit plus £10 wager and valid for seven days, with anything won paid straight to cash.

Backing that up is a 2,700-game library including 200-plus progressive jackpots (joint-deepest with Ladbrokes), Betfred-exclusive slots, 100-plus live tables and one of the fastest cash-out routes on the market via Visa Fast Funds, alongside ongoing promotions — the Free Spins Accumulator, Mystery Free Spins, Prize Reel and Comp Points — that keep the value ticking after the welcome expires.

• Three-way welcome bonus choice - rare on this list
• 200+ progressive jackpot slots (joint-deepest with Ladbrokes)
• Information on each slot game contains RTP

• No Evolution Gaming live dealer tables (industry gold standard)
• Poor site navigation - slots split between Casino and Vegas sections

MrQ Casino

MrQ leans hard on high-RTP studios, such as Pragmatic Play, Play'n GO, Hacksaw and NetEnt, and always serves the highest available RTP where a slot has variable rates, while they backs every bonus with a blanket no-wagering policy so any win drops straight to withdrawable cash.

Like Betfred, MrQ publishes RTP and volatility at the top of each slot's game page alongside reels, paylines and stake range, giving players the data to pick the best-returning titles rather than guess.

MrQ’s usual welcome offer is 100 no-wagering free spins after a £10 minimum deposit, but using your exclusive promo code POTS300 new users can receive 300 free spins. In either version of the offer, spins are worth 10p each, and must be used within 48 hours.

MrQ’s Refer-a-Friend programme provides 100 no-wagering free spins per referral but otherwise the promo calendar is quite thin - which is disappointing considering there is no VIP programme.

• Wager-free since 2018 - the original UK no-wager casino
• Curated high-RTP studio mix from Pragmatic Play, Play'n GO, Hacksaw and NetEnt
• Independent UK operator with no parent group

• Smaller library than rivals on this list (1,200+ games)
• Limited ongoing promotions outside the referral scheme

Highest payout casino games based on RTP

We’ve highlighted some of the top payout casino sites, but what are the games bettors should be on the look out for?

The figures below are long-term RTPs published on each game's information panel. As such, individual sessions will vary, and it should be remembered that some slots have configurable RTPs, meaning operators can choose between different RTP versions of the same game.

To stay ahead of the curve, check the in-game info panel before you spin.

Highest RTP slots UK at best payout casinos

The highest RTP slots typically sit at percentages between 94% and 97%, but there are a handful of standouts above 98% and even the rare 99% title that crops up.

NetEnt’s Mega Joker and Relax Gaming’s Book of 99 both sit at the highest RTP of 99%.

Mega Joker is a classic 3-reel, 5-line title featuring mystery wins, a progressive jackpot, and a Supermeter mode, where winnings from the basic mode are used.

Book of 99 is a Greek mythos-themed 3-reel, 5-line slot with a bonus round that triggers with either three-symbols or by collecting 99 books.

Thunderkick’s 1429 Uncharted Seas sits just below at 98.60%, and is a five-reel slot with 25 pay lines. There’s also a bonus round with free spins.

Blood Suckers is another NetEnt slot, with RTP at 98%. One of the oldest games on this list, launching in 2009, Vampire-themed Blood Suckers is five reels and three lines, with a bonus round and 25 pay lines.

NextGen Gaming is the studio behind Starmania, with the standout feature being the double-up bonus round. It has a RTP of 97.87%, just above Big Time gaming’s White Rabbit Megaways.

White Rabbit Megaways’ unique feature drop allows players to buy the feature at any time, with a price set at the beginning of the game. The price drops every time the player gets a BTG coin.

Highest RTP table games

There are three main table game categories - blackjack, baccarat and roulette. The RTP changes for each game, but this is dependent on whether the optimal strategy is followed when playing.

Blackjack tables offer single-deck blackjack, which when played with basic strategy returns around 99.50% RTP - making it the highest RTP of any standard table game. Multi-deck variants run a touch lower, between 99.0 and 99.3%.

Remember, the player must use basic strategy to hit these figures. Bad intuition or strategy drops the effective RTP by several percentage points.

On Baccarat tables the banker bet returns 98.94% RTP and is the highest-RTP single bet in the game. The player bet sits at 98.76%, whilst the tie bet is 85.64% and should be avoided. Bettors who simply bet banker every hand are playing one of the highest-RTP table bets in any UK casino.

Roulette RTPs can depend on the variant of roulette being played.

European Roulette, or single zero roulette, returns 97.30% RTP - which is reliably higher than American Roulette or double zero roulette, which sits at 94.74%.

French Roulette with La Partage or En Prison rules pushes RTP up to 98.65% on even-money bets, but this variant is rarer at UK casinos. When possible, choose European roulette over its American cousin for highest-RTP.

All eight casinos on this list offer the above games in both virtual (RNG) and live dealer formats.

Highest RTP video poker

Video poker is the highest-RTP category at any UK casino - but only when it is played with optimal strategy.

Jacks or Better with full-pay paytables and optimal play returns 99.54% RTP, for example.

Other high-RTP video poker variants include Deuces Wild with full-pay paytables, which can return above 100% RTP in theory - the only casino game where this is possible.

That being said, full-pay Deuces Wild is rare at UK casinos in 2026. Joker Poker - Kings or Better - sits at around 99.07%.

Just like the live tables, video poker requires the player to use correct strategy to hit the highest possible RTP figures. Poor play will drop the effective RTP by a significant amount. To find the best strategies, there are free strategy charts widely available online.

Of the casinos listed on this page, Grand Ivy, Bet365 and Ladbrokes carry the deepest video poker selections.

January 2026 wagering and bonus rules

All welcome offers on this page reflect the UKGC's January 2026 rule changes - when wagering requirements were capped at 10x on casino bonuses, and mixed sport/casino bonuses were banned.

As such, welcome offer structures have changed during the course of 2026. Some brands listed here now pair the cap with no-wagering free spins - which beat 10x wagering requirements entirely.

However, before you claim an offer, bettors should verify eligible games and other restrictions such as the max bet on bonus funds, free spin expiry and excluded deposit methods.

How we rank best payout casinos and what to look for

We only feature UKGC-licensed sites. If a best payout casino can't show its licence, it doesn't make the list.

The Standard’s betting experts rank operators on the following criteria, and we recommend you also consider the following factors when making your own choice of online casino.

1. RTP transparency - Casinos should publish per-game RTP figures, either inside each game or on a dedicated site-wide page in the footer. It is a big red flag for readers if these figures are hidden - and it disqualifies a brand from our ranking.
2. Depth of high-RTP catalogue - We see if a casino has a wide selection of 96%-plus titles across slots, table games and video poker. One or two high-RTP slots is not enough - readers should not be forced into a single game to access favourable RTPs.
3. Real welcome offer value - Headline figures matter less than you might realise after considering wagering requirements, max win limits, and excluded payment methods. Readers should always read the T&Cs before claiming any welcome offer.
4. Ongoing promotions for existing players - A casino site may have an enticing welcome offer, but if there are no daily and weekly bonuses, cashback and reload offers, it lacks replay factor or long-term worth.
5. Responsible gambling tooling - Casino should clearly highlight tools such as deposit limits, time-outs, reality checks, self-exclusion, and GAMSTOP integration as well as visibly signpost links to GamCare and GambleAware. Readers should set a deposit limit before depositing and always view casinos as a form of entertainment, not income.

Responsible gambling

UKGC-licensed UK casinos are required to provide a baseline set of responsible gambling tools, including but not limited to deposit limits, time-outs, reality checks, and self-exclusion. Most also integrate with GAMSTOP for permanent self-exclusion.

The Standard recommends setting a deposit limit whilst creating your account, taking regular breaks during play, and treating any winnings as bonus rather than expected returns - casino games are designed for entertainment, not a reliable source of income.

High-RTPs are not a guarantee of profit. If you need free, 24/7 support, you can call GamCare on 0808 8020 133, visit BeGambleAware.org, or search for GAMSTOP - a free self-exclusion service that works across all UK-licensed gambling sites.

Best payout casinos FAQ

Which online casino has the best payouts in the UK?

Grand Ivy Casino’s transparency on RTP figures highlights its position as one of the best payout casinos in the UK, whilst Pub Casino’s headline published payout percentage sits at 96.10%. Remember, ‘best’ can be subjective beyond the pure numbers, as it can depend on whether you value transparency, library depth or availability of a specific game category.

Which online slots have the best payouts?

Mega Joker and Book of 99, provided by NetEnt and Relax Gaming respectively, both publish RTP percentages of 99.00%. This makes the two slots the joint-highest among mainstream UK slots.

Thunderkick’s 1429 Uncharted Seas at 98.60% and NetEnt’s Blood Suckers at 98.00% follow closely. Popular choices, all four are available at multiple casinos on this list.

What casino game has the best odds for a payout?

If played with the optimal strategy, Jacks or Better video poker has a RTP of 99.54% - the highest of any mainstream UK casino game.

Single-deck Blackjack with basic strategy follows closely at around 99.5%. Both require correct strategy to hit those figures - poor play can drop the effective RTP quite significantly.

What is the highest RTP casino in the UK?

Pub Casino publishes a 96.10% operator-wide payout percentage - the only headline figure of its kind on this list.

Grand Ivy Casino doesn't publish a single number but its per-game RTP page shows slots between 96% and 97%, with table games at around 99% and virtual games just below with RTPs at about 94%. This translates to a similar or a higher blended figure depending on the game mix.

What is a casino payout rate?

A casino's payout rate is the percentage of all stakes the casino returns to players as winnings, averaged across every game. Essentially, it is RTP measured across the whole site rather than for a single game. The industry average in the sits around 95 and96%, whilst the best payout casinos publish figures of 96% plus.

Are high-RTP casinos safer than low-RTP ones?

RTP is a measure of the casino's house edge, not safety for users. A 'safe' casino is one with a valid UKGC licence, shown in the footer, with evidence of independent game-fairness audits from companies such as eCOGRA, iTech Labs, or GLI.

UKGC-licensed casinos should also have responsible gambling tooling and a clear complaints route via IBAS. All eight casinos on this list meet those criteria - RTP simply tells you the maths.

We aim to offer every online gambler and reader of The Standard a safe and fair platform through unbiased reviews and offers from the UK's best online gambling companies.
