TOP 15 BEST-PAYING UK SLOTS

If you want to have the best chance of winning at slots, you need to take a few essential steps.

First, you need to understand the Return To Player (RTP) percentage.

The RTP is the term that online casinos use to describe the percentage of all the wagered money a slot machine will pay back to the player over time.

Bonus funds are separate to Cash funds, and subject to 35x wagering (bonus + cash). Terms apply. Play Responsibly. BeGambleAware.org

The RTP is always calculated over the long term, so all variance (highs and lows) is evened out. The second step is to check to RTP of the slot to find out how well it rates on the RTP scale:

• 93% or less: subpar RTP
• between 93% and 95%: weak RTP
• between 95% and 97%: good RTP
• between 97% and 98%: excellent RTP
• higher than 98%: superb RTP

The higher the RTP, the more favourable the odds are for you as a player and the bigger the chance that you will win on that particular slot. The best paying slot games will always offer you a high RTP percentage, making them some of the best slots to play in the UK.

How can you check the RTP?

Most slots have the RTP listed in the rules or paytables of their game.

Sometimes you have to look for it, but most software providers are happy to provide the RTP. If you cannot find the RTP, we advise you to consider playing a different slot.

Which online slots guarantee a profit?

Unfortunately, there are no slots that will guarantee winning sessions.

The RTP would have to be higher than 100%, which would mean the online casino site would be bankrupt within a few days.

However, the good news is that some online slots have an RTP that is very close to 100%. And remember, the closer the RTP comes to 100%, the better odds you have of actually beating the casino. The best paying online slots will almost always offer you a fantastic RTP percentage.

The Best Online Slots to Play Based on RTP

Find our exclusive table below dedicated to the top 40 slots with the best RTP value.

We have also included the best online casino sites to play each high paying slot game. The top 10 online slots on the list below come highly recommended by us.

Interesting facts about RTP

Big-name or franchised slots, often how lower Return To Player. Game developers have to pay significant sums of money to use the name and images for franchised titles such as The Terminator, Jurrasic Park or The Marvel range slots from Playtech. These fees have to come from somewhere, so in the end, the player pays for them through a lower RTP.

In our top 15 list of Highest Paying Slots, you will mainly find Netent, Thunderkick and (to a lesser extent) Microgaming titles. No Nextgen, WMS, Playtech, Ballys, or Yggdrasil slots had a high enough RTP to make the top 15 list.

Progressives slots have the lowest RTP percentages by far, often 8-10% less than those in our top 10 list. And that percentage includes all the enormous progressive jackpot amounts, so the RTP on the base game is even significantly lower. If you want to get some decent play time, avoid progressive slots.

There are two exceptions to this rule: 1. when the progressive is at an all-time high or 2. if you are playing with bonus money.

Smart players play slots with high RTP!

Whether you prefer low to medium variance slots or high variance slots, if you want to have a solid chance of beating the slots, we advise you to pick a title from our top 15 best paying slots list. Remember that Thunderkick, Netent and Microgaming often have better Return To Player percentages than other slots developers.

Don't forget, Megaways slot games often come with a high RTP percentage. You can also use your PayPal wallet to play slots with high payouts.
