Though the industry average is 96%, the RTP of slots can vary wildly depending on the publisher, casino, and other factors. But, what the the best RTP slots in the UK, and where can you play them?
Here are Gambling Zone’s best slot sites to play slots with the best RTPs.
Why Does the RTP of a Slot Matter?
The RTP of a slot stands for “return to player”. This is the theoretical amount that the player could expect to earn back from the slot. RTPs are displayed in percentages which can help the player to calculate how much the slot may pay out. For example:
On a slot with a 95% RTP, a player waging £100 may expect to earn back £95. A slot with a 94.85% RTP would have an expected payout of £94.85 on a £100 wager, and so on.
Given this logic, choosing to play a slot with a higher RTP should result in a higher return on a player’s investment, which is why they remain popular with a range of players. However, it is always worth remembering that this percentage is only theoretical, and not guaranteed. Slot games are games of chance at their core, so there are never any guaranteed winnings.

Caveats with High RTP Slot Games
While UK slots with the best RTP may seem enticing, it is worth remembering that these statistics often come with certain conditions or caveats. Here are some things to keep in mind.
- The RTP is not guaranteed: RTP percentages are an approximation based on averages when the game was tested. This means you will not get exactly what the RTP is back from the slot every single time you play. Expect the amount to fluctuate, especially with higher volatility slots.
- Some slot games have conditions to meet before reaching the max RTP: Some slot games may theoretically have a high RTP, but in practice you will not see this right away. If we take Mega Joker as an example, the maximum RTP advertised is 99%, but this is only when using the “Big Bet” feature.
- The RTP will vary between online casinos: Depending upon the maths model and game version used, the same slot game may have a different RTP at different casino sites. Always check the advertised RTP at your online casino of choice before playing.
- RTPs can change: Everything we have mentioned is subject to change. Although correct at the date of writing, you should always double-check that the RTP of the slot game you want to play is unchanged by the developer or the casino.
