All best payout casino sites hold current UKGC licenses. RTP data reflects verified audit reports from eCOGRA and iTech Labs. If you want even more casino options, visit our casinos hub.
How We Verify and Rate the Best Payout Casinos
We verify payout rates by analysing the audit report and testing the game rather than relying on the casino marketing claims.
Our 3-Step Payout Verification Process
Step 1: Analyze Official Audit Reports
We locate and analyze eCOGRA, iTech Labs, and GLI audit reports for each highest payout casino. These independent testing labs audit casino RTP monthly or quarterly. Reports show:
- Average RTP across all casino games
- RTP breakdown by game category (slots, table games, live dealer)
- Month-by-month payout percentages
- Verification that games operate fairly
We verify audit reports are current (under 6 months old for current data). We check auditing body is legitimate and recognised. We compare the casino’s stated RTP with what the audit really displays.
Step 2: Test RTP of 100+ Slots at Each Casino
Furthermore, we play multiple different slots at each casino and over extended sessions. We track:
- Advertised RTP for each game tested
- Our observed win frequency over sessions
- Whether games feel fair during extended play
- RTP display transparency in game info
We can’t verify exact RTP through limited play (would require millions of spins). But here’s what we can actually do: check if the games perform reasonably and if the RTPs the sites display really match the ones from the audit reports.
Step 3: Compare Advertised RTP with Audit Findings
- Check whether casino’s game RTP claims match audit data
- Verify RTP displays on games match official reports
- Identify any discrepancies between claims and audits
- Confirm transparency in RTP reporting
| Verification Component | What We Check |
| Audit Report | eCOGRA/iTech Labs current reports |
| Game Testing | Extensive slots played per casino |
| RTP Display | Transparency on all games |
| Data Matching | Claims vs audit verification |
Our Ranking Formula (Audited RTP is 50% of the score)
The average RTP we audited weights about 50% of our best payout casino rating. Other factors include the ones you will see below:
- RTP transparency (displaying clearly on games): 20% of score
- High RTP game selection (number of 97%+ games): 15% of score
- Audit report accessibility (easy to find): 10% of score
- Game variety at high RTP levels: 5% of score
A casino with high audited RTP but poor transparency scores lower than a best payout online casino with slightly lower RTP displaying clearly on every game.
Our Commitment to Data-Driven Analysis
Our ratings rely on verifiable data from independent audits rather than subjective opinions. We cite audit bodies and RTP percentages. We make a distinction between the theoretical RTP and how it performs during audits.
When choosing best payout casino UK sites, you can trust this data-driven approach as it provides reliable information.
Return to Player (RTP) Explained: A UK Player’s Guide
As soon as you understand RTP, you can choose best payout online casino sites and games offering better mathematical odds of winning over time.
What is RTP and How Does it Affect Your Winnings?
RTP (Return to Player) represents the percentage of all wagered money a game returns to players over time. A 96% RTP slot returns £96 for every £100 wagered across millions of spins.
Important clarifications:
- RTP is theoretical average over millions of spins, not guaranteed per session
- Higher RTP means better long-term odds, not guaranteed wins
- RTP includes big wins and small wins averaged together
- Individual sessions can vary wildly from theoretical RTP
How this affects your play:
Let’s say you choose 97% RTP over 95% RTP. This means that you are keeping £2 more per £100 wagered on average. Over time and extended play, this difference compounds. So, playing high RTP games gives you better mathematical odds, but keep in mind the fact that those individual sessions still involve luck and variance.
Casino-Wide RTP vs Individual Game RTP
A simple definition would be that casino-wide RTP is the average of all games combined. Yet, each game’s RTP can range from 85% to over 99.5%, but this depends most of the time on what you’re playing.
Casino-wide average RTP:
- Combines slots, table games, and live dealer into single percentage
- Best payout casino UK sites average 97%+ across all games
- Varies based on game mix (more blackjack raises average)
- Useful for comparing overall casino fairness
Individual game RTP:
- Each slot has specific RTP (Starburst 96.09%, Gonzo’s Quest 95.97%)
- Blackjack RTP depends on rules (99.5%+ with optimal strategy)
- Roulette RTP fixed by wheel type (European 97.3%, American 94.74%)
- Choose individual games by their RTP, not just casino average
Consider our piece of advice and always check each game’s RTP instead of relying only on the casino average. Because a casino with 97% average might have low-paying slots mixed with 99% blackjack, and this offers and overall better value.
How to Find the RTP of Any Casino Game
For slots:
- Open the game you want to play
- Look for “i” info button (usually top or bottom corner)
- Click to open game information screen
- Find RTP percentage listed in rules or paytable
- Verify percentage matches audit reports if available
For table games:
- Blackjack: Check rules (dealer stands on soft 17 = better RTP)
- Roulette: European (97.3%) better than American (94.74%)
- Baccarat: Banker bet (98.94%), Player bet (98.76%)
- Rules determine RTP more than casino for table games
For live dealer:
- Same RTP as standard table games
- Check rules displayed at table
- European roulette offers better RTP than American
- Blackjack rules vary by table (check before playing)
Most UKGC casinos display RTP on games as industry best practice. If you can’t find RTP easily, this indicates lower transparency standards.
The Highest Paying Casino Games in the UK
As expected, different game types offer vastly different RTP rates. Choosing high RTP games improves your mathematical odds.
Blackjack (99.5%+)
Blackjack has, indeed, the highest RTP of any casino game, but this only applies when you use the basic strategy to play it.
Why blackjack RTP is highest:
- Based on mathematical optimal play, not luck alone
- Player decisions affect outcomes unlike slots
- Optimal basic strategy reduces house edge to 0.5% or less
- RTP reaches 99.5%+ with favorable rules
Rules affecting blackjack RTP:
- Dealer stands on soft 17: Better for player
- Surrender allowed: Increases RTP
- Double after split allowed: Better odds
- Blackjack pays 3:2 not 6:5: Essential for RTP
- Fewer decks: Generally better RTP
You should see our blackjack sites guide if you want to find a detailed blackjack strategy and more casino options.
Video Poker (99%+)
Video poker offers second-highest RTP when played with optimal strategy.
Top video poker variants by RTP:
- Jacks or Better (Full Pay): 99.54%
- Deuces Wild (Full Pay): 99.73%
- Double Bonus Poker: 99.11%
- All American Poker: 99.38%
Video poker RTP depends heavily on paytable. “Full pay” variants offer highest RTP. “Short pay” versions reduce RTP by 1-3%. Always check paytable before playing.
High RTP Slots (97%+)
Slots typically offer lower RTP than table games but some reach 97%+ providing better odds than average slots at 94-96%.
Top 20 Highest RTP Slots Available in UK:
These high RTP casino slots are available at most UKGC sites. Always verify RTP in game info as some casinos use lower RTP versions of same games.
How to Find a Casino’s Audited Payout Report (eCOGRA & iTech Labs)
What independent audit reports do is to verify casino payout rates. In this section, you will find the steps to locate them, and more explanations.
Step-by-step process:
- Check casino footer: Look for links labeled “Payout Reports,” “RTP Reports,” or “Fair Gaming”
- Visit responsible gambling section: Some casinos publish reports here
- Check About Us or Trust pages: Audit information often appears in transparency sections
- Search “[Casino Name] eCOGRA report”: Google search often finds reports directly
- Contact customer support: Ask where audit reports are published
What to look for in audit reports:
- Report date (should be under 6 months old for current data)
- Auditing body name (eCOGRA, iTech Labs, GLI are reputable)
- Average RTP percentage across all games
- Breakdown by game category if provided
- Verification that RNG (random number generator) operates fairly
Don’t ignore the fact that if a casino doesn’t publish audit reports or makes them difficult to find, this basically means they are not as transparent as those operators that are publishing more prominently.
Volatility vs RTP: What’s the Difference?
Many players from the UK confuse RTP with volatility. As soon as you understand each of these two terms, it helps you choose games that match how you like to play.
RTP (Return to Player)
RTP measures how much a game pays back over time as percentage:
- 96% RTP returns £96 per £100 wagered over millions of spins
- Theoretical long-term average, not session guarantee
- Higher is always better for player odds
- Doesn’t indicate win frequency, only total return
Volatility (Variance)
Volatility measures win frequency and size distribution:
- Low volatility: Frequent small wins, rare big wins, steady bankroll
- Medium volatility: Balance between frequency and size
- High volatility: Rare wins but potentially massive when they hit
Key distinction:
- High RTP, Low volatility: Best mathematical odds with steady play (Blood Suckers 98%)
- High RTP, High volatility: Good odds but wild swings (Dead or Alive 96.8%)
- Low RTP, Low volatility: Lower mathematical value despite frequent small wins
- Low RTP, High volatility: Least favorable combination for players
You should ultimately choose according to your goals. Prefer steady play? High RTP low volatility. Chasing jackpots? High RTP high volatility acceptable. Always prioritise high RTP regardless of volatility preference.
Do Best Payout Casinos Offer Good Bonuses?
Some players wonder whether high RTP casinos compensate with smaller bonuses. Our analysis reveals the relationship.
We compared bonus offerings at best payout casino UK sites (97%+ average RTP) versus lower RTP operators (95-96% average). What we noticed was that high RTP casinos offered welcome bonuses of similar size. Wagering requirements showed no real difference. Plus, free spins amounts were about the same.
What we found:
- High RTP casinos don’t systematically offer smaller bonuses
- Bonus quality is independent of payout rates
- Some high RTP casinos like Casumo offer competitive bonuses
- Some lower RTP casinos offer modest bonuses despite lower odds
The consideration: High RTP casinos that have generous bonuses basically give you the best overall value. You get better odds on games, plus that extra bonus money. This combination beats, on one hand, high bonuses with poor RTP, and on the other, high RTP with small bonuses.
Casumo combines high average RTP with competitive bonuses. LeoVegas pairs extensive high RTP slots with solid offers. This means that you don’t have to choose between good odds and bonuses.

Common Myths About Casino Payouts
Several myths about high payout casino sites persist amongst British players, even though they are not mathematically true. Let’s examine the reality.
- Myth 1: Slots are “hot” or “cold”
Reality: Every spin (or round) is both independent as well as random. Previous results don’t affect future spins. RNG (random number generator) ensures each spin has identical odds. A slot that just paid a jackpot has the same chance of paying again next spin. “Hot” and “cold” streaks are perception, not reality.
- Myth 2: Casinos can adjust RTP remotely during your session
Reality: UKGC regulations do not allow casinos to change RTP without receiving approval first. Game RTP is fixed in software certified by testing labs. Best paying online casino sites can’t modify RTP mid-session or target individual players. Your RTP remains constant throughout play.
- Myth 3: Higher stakes improve RTP
Reality: RTP stays identical no matter the stake size in most games. Betting £10 per spin versus £1 per spin doesn’t change 96% RTP. Some progressive jackpot slots have slightly higher RTP at max bet, but base RTP remains fixed.
- Myth 4: Time of day affects payout rates
Reality: RTP operates identically 24/7. Playing slots at 3 AM offers same odds as 3 PM. RNG doesn’t know what time it is. This myth likely stems from confirmation bias when players win during specific times.
- Myth 5: New casinos have higher RTP initially
Reality: RTP is fixed in game software, not casino settings. New casinos offer same RTP as established operators for identical games. Starburst pays 96.09% everywhere regardless of casino age.
- Myth 6: You’re “due” a win after losing streak
Reality: Each spin or hand is independent. Previous losses don’t increase future win chances. This is gambler’s fallacy. RTP operates over millions of rounds, not individual sessions.
The facts:
- RTP is mathematical average over millions of rounds
- Every spin/hand is independent and random
- Casinos can’t manipulate RTP remotely
- Previous results don’t predict future outcomes
- Time of day doesn’t affect odds
- Stake size doesn’t change RTP (except rare exceptions)
To conclude with, once you understand these facts, you can make smart decisions that are based on maths rather than superstition.
