Our ultimate goal is to direct you to the most RTP-rich casinos out there. You'll have a better chance of winning money if you take advantage of high payout percentages on a regular basis.

Check the RTPs in the Game.

RTPs play a major role in our evaluations when looking for the best casino for payouts. Using the RTP percentage, a casino game's average payout can be determined. This means that, on average, a slot machine with an RTP of 97 percent will return 97p (£0.97) for every £1 spent. If you bet £1, you'll get 97 cents back on every spin, but that doesn't mean you'll get 97 cents every time.

It's possible to beat the RTP (and make money), and it's possible to lose to it (and lose money) (the casino makes a profit). Even so, the RTP is a reliable predictor of a game's likelihood of paying out winnings. Even though we talk about return to player (RTP) in our casino and slot machine evaluations, you can find this data on your own. A game provider's RTP is listed on their website, while a casino operator's RTP is often listed on their site.

Examine the Terms and Conditions

Finding a casino's RTP on the website highlights the importance of reading the terms and conditions prior to signing up for an account. You can learn more about the requirements and restrictions by familiarising yourself with the terms and conditions. The same goes for online casino bonuses, which frequently come with terms and conditions like wagering requirements, game eligibility quotas, and payment method restrictions.

When writing our reviews, we take care to point out important terms and conditions, but you can easily find this information at any online casino you choose.


High-paying slots with the biggest jackpots draw a lot of players to online casinos. Naturally, the most volatile online slot games are those with the highest jackpots. Online slot games with massive jackpots have a higher volatility rate, meaning a greater risk is involved when playing.
