How do we choose the high payout slots for this list?

Before selecting the best high payout slot on our list, we carefully considered some key factors to make sure you have a memorable gaming experience. We prioritize RTP (96% or higher) for better long-term returns, like Immortal Romance (96.86%). The volatility and max win potential also matters. 

Finally we prioritise slots with simple game features (free spins, multipliers), trusted casino software providers (e.g., Pragmatic Play) and that they're available at top UK casinos.  

What Is a High Payout Slot?

A high payout slot gives you better chances to win big compared to regular slots. Several things make these games special. For one, they feature high payout potential that can reach up to 5,000x your bet and bonus features, like free spins or wilds that are guaranteed to boost your winnings.

Volatility is another factor. High volatility slots pay big but less often while low volatility slots give smaller but frequent wins. The biggest factor is Return to Player (RTP), which shows how much a slot pays back over time. A 97% RTP means you get £97 back for every £100 you bet.

The best paying casino games usually have an RTP above 96%, with top ones like fat rabbit hitting 96.45%

What Is the Difference Between High Payout Slots and High RTP Slots?

High RTP slots and high payout slots sound similar, but they’re quite different. High RTP slots are slots with RTPs above 96% and focus on steady, smaller wins over time. 

High payout slots, like Gates of Olympus, mix high RTP with big rewards from bonuses, like free spins or multipliers.

Why High-Payout Slots Offer More Than Just Bigger Wins

For players in the UK, choosing a slot isn't just about the theme or the graphics it’s about value. Because of the strict standards set by the UK Gambling Commission (UKGC), the high-payout market in Great Britain offers unique legal protections and perks that you won't find elsewhere.

If you're looking to make your bankroll go further, here are the top reasons why high-RTP slots are currently dominating the UK market:

Transparency

In the UK, every game must display its RTP (Return to Player) percentage in the help files by law. High-payout slots in the UK are often from "Tier 1" providers (like NetEnt, Play’n GO, or Blueprint Gaming) that undergo rigorous testing by agencies like eCOGRA.

You have the peace of mind that a "97% RTP" game has been mathematically verified to be fair, unlike in less regulated markets.

Maximizing "Feature Buys"

While the UKGC banned the "Buy Pass" (paying 100x your bet to skip straight to the bonus) a few years ago, high-payout slots often have a more frequent "Natural Hit Rate" for bonuses.

High RTP games often focus on the "main game" experience. This means you aren't just sitting through hundreds of "dead spins" waiting for a bonus that might never come; the base game paytable is usually stronger.

Better Value for Wagering Requirements

If you’ve claimed a casino welcome bonus (e.g., "Deposit £10, Get £30"), you likely have to "wager" that money 35x before you can withdraw it.

UK players use high-payout slots to "grind" through these requirements. Because the house edge is lower, you have a statistically better chance of having money left over once the wagering is complete.

Safer Gambling Controls

Because high-payout games often involve higher stakes, the UK versions are built with mandatory time-out and spend limits. You get the high-end experience without the wild west lack of oversight found in offshore casinos.

Where can I find the RTP on an online slot?

You can find a slot’s return to player in the game’s paytable or info section, often under an “i” or “?” icon. Check the casino’s website under the slot’s description or the provider’s official site. You can also find such information on the review section of Racing Post. Note that RTPs may vary slightly by casino due to adjustable settings, so verify with the operator.
