Every casino offers slots and table games that guarantee a long-term payout. The payout is known as the RTP (Return to Player percentage) and is the average return made to players over millions of games.
By accumulating all RTPs on a site, you can gauge how much a casino pays out to its players. Some highest payout casinos list individual RTPs on their online game pages. Others, however, will list RTPs for all classifications of games on their test certificates.
Under gaming rules, licenced online casinos must be audited by independent testing labs like eCOGRA. Testing bodies will conduct in-depth analysis on software to judge whether the random number generators are fair and that payouts are accurate.
You’ll usually find a test certificate displayed on the online casino site. You may also find a breakdown of payouts for individual games like slots and roulette.
How RTPs Are Determined
Every licensed in UK online casino has a payout percentage programmed into the game. This is a theoretical figure based on millions of spins over time.
For instance, a slot with an RTP of 97% will pay out on average £97 for every £100 paid in. The remainder is kept by the casino. In this case, the casino would keep £3 of every £100 bet on that particular slot.
The best online casinos only feature slots with high payouts. bet365 casino, Betfred casino, Unibet are among the best payout casinos in the UK to play at. You might find bonus slots with RTPs of 98% or big-money progressive jackpots that pay out huge sums. They all also offer apps, a number of popular payment methods and bonuses to new customers.

Finding Big Jackpot Games & Slots
Before you sign up to a casino, look at the game lobby. There you’ll find a list of all games and slots. There may also be a separate jackpot tab filled with progressives where you can win up to a million pounds. And of course, the more popular the casino, the bigger the jackpots.
Not all software developers provide big payout games. Some providers are known for supplying games with low returns for players. It’s advisable, then, to look for top payout casinos that spread a good range of developers.
You should also look at game volatility. Volatility refers to the frequency with which a game pays out. It’s good to have high-volatility slots that can trigger lots of bonus features. However, volatile slots can be high-risk and you may experience a downswing before seeing any results.
On the other side, slots with low volatility don’t pay out a lot of big jackpots. They tend to be steadier, paying out little and often. Overall, low-volatility slots will bring down the casino’s overall return to player payouts.
If you’re into table games, look for a good range of variants with low house edges. American Roulette is notorious for a high house edge of 5.26%, for instance, so look for a casino that also boasts French Roulette and European Roulette.
