top 15 top paying slots


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

First of all, you need to understand what the Return To Player (RTP) percentage is of a slot machine. 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. In other words, how much of the money that is put in, is given back to the player?

Casino Heroes

  • Great game selection
  • Fight Boss Battles and explore Islands
  • Win extra free spins and Rubies
  • Fast payouts
  • Speedy account verification

For example, if the RTP of a slot is 94%, you can expect to get £94 back for every £100 that you put in. 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: low RTP
  • between 93% and 95%: acceptable RTP
  • between 95% and 97%: great 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.

Tip: Dazzle Me: 96,9%

Play at: Vera & John

Dazzle Me is a very popular Netent slot with a somewhat different 5 reel set up with 76 win lines. It features stacked symbols, identical reels and a free spins bonus. The RTP is a very respectable 96.9% which just falls short of our top 15 list but is very impressive nonetheless.

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 slots guarantee a profit?

Unfortunately, there are no slots that will guarantee a win. The RTP would have to be higher than 100%, and that would mean the online casino would be bankrupt within a few days. The good news, however, 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.

Interesting facts about RTP

Big name or franchised slots, as a rule, have a low Return To Player. Game developers have to pay significant sums of money to be able 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 the ones in our top 10 list. And that percentage includes all the big 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 a 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.

Progressive slots can make you a millionaire overnight but also have some of the worst odds for casino players.
