What is rtp?

RTP stands for Return to Player.  In essence the RTP of a slot is simply the average amount of money a player will win.  For example, if a slot has an RTP of 92% and a player makes £1,000 in bets, then the amount of winnings should even out at around £920.  Now, this isn’t always the case with £1,000 in bets because these RTP figures are based on hundreds of thousands of spins.  But it certainly gives you a good indicator of where you should be focusing your slots game play.

In a nutshell, the higher the RTP, the more often the slot machine pays out.  Why leave it to chance?  There’s no sense in paying to lose when you can access the necessary information right here in order to give yourself the best possible chance of bigger and more regular wins.  We’re here so you don’t have to focus on anything other than the best payout online slots in the UK.

So let’s get to it.  See below for our up to date list of the best 10 RTP slots currently on the market.

It’s not just the slots that are important.  Choosing the right slot is just the first and most important step.  Next you need to find a fair, safe, reliable casino that will provide the service you’re looking for.  It only takes a quick google search to find out that there are so many casinos online who don’t provide that service.

We have our own personal check list when we’re looking for a new casino to play at.

  • The casino must be UK licensed
  • The casino must not have a maximum withdrawal
  • The casino must have reasonable bonus terms
  • The selection of games available must be ample

To save you time.  We’ve selected 5 of our favourite casinos that fit the description above.  The combined RTP of all the games in each of these casinos are a rival buster in that the slots on these casinos generally pay out better than the slots on others.  It’s so important to play at the right casino, after all, when you do hit your big wins, you want to be sure that the casino will pay you promptly and without fuss.


Of course, there’s more to slots than simply the RTP.  Slots machines need to be fun to play and interesting to use.  That’s why we also review each slot for play-ability.  There’s nothing worse than endlessly spinning a boring slot, no matter how god the RTP is.   So here at Highest RTP slots you’ll find a balance between finding the highest RTP slot and the most fun slot to play.  So with responsible betting, you can have fun at the same time as giving yourself some really powerful ammo with wins in your sights.
