Highest Paying Online Slots 

There are oodles of different slots out there. Some of them brilliant, others not quite so much. Now, we know the reason most of you are playing slot machines. It is the fact that you want to have some fun while winning some cash. In fact, the latter is probably the most important to you.

That is why we decided to compile a list of some of the highest paying slot machines in the world. These are games where your chances of winning are higher than anywhere else. Before we dive into that list, however, we want to talk a little bit about what makes a high paying slot machine…high paying!

How Do We Determine What a High Paying Slot Machine Is?

To determine what a high paying slot machine is, we look at something known as ‘return to player’, or RTP % for short. This is the amount of money that (as you may have guessed), gets returned to the player. Let’s say the RTP on the machine is 98%. For every £100, you can expect to get £98 back. Now, obviously, it is not going to completely pan out like this. Some people are going to make a profit, others are going to make a loss. The RTP is the ‘average’ over all the players that are playing that game. Of course, the higher the RTP is, the more chance you have of winning.

We recommend that you look for slots with a minimum 93% RTP, although the higher, the better. You will notice that many of the slot machines that we cover on this page are going to be more than 97%. 

It is worth noting that the ‘branded’ slots tend to have a lower payout rate. This is because the slot machine designer needs to cover the cost of the licence. As you go through this list you will notice that many of these games are ‘unbranded’ slots. You may not even have heard of most of them. Don’t worry, they are all great and offer a higher payback to player percentage than most other UK slots on the market.

Monopoly Big Event – 99% RTP (Barcrest)

monopoly big event slot rtp %If you wish to enjoy the 99% RTP that Monopoly Big Event boasts, you are going to need to play in the ‘big bet mode’. This is where you will need to plump up a minimum of £30 for five ‘’enhanced spins’. The RTP when you are veering away from ‘big bet mode’ is a little bit lower.

The potential to win here is massive. It is not going to be a slot for those ‘low rollers’ with the minimum bet of £30, but you should be able to get a reasonable proportion of that. The game does throw in free spins, so you may end up getting more than those 5 spins for your money. A fantastic slot, especially for those who love a traditional game of Monopoly!

Mega Joker Slot – 99% RTP (NetEnt)

mega joker slot rtpThis is about as classic as online slot machines get! 5 win lines, fruit and bell symbols, you know the drill. Mega KJoker Slot is a perfect introduction to the world of online slots for newer players.

This is also another slot where you are only going to be able to enjoy the massive RTP if you are betting during a special game mode. In Mega Joker Slot, this is known as ‘supermode’. Bets are slightly higher than the normal game, but the chances of winning are going to be massive and are well worth bet that mich higher as it could really pay off.

1429 Uncharted Seas – 98.6% (Thunderkick)

1429 uncharted seas rtp %If you want a gorgeous-looking slot machine, one which is definitely unique, then 1429 Uncharted Seas Slot is the route to go down. This game boasts a free spins game, expanding wilds, and of course what we're all interested in here: massive payouts!

The best part is that with 1429 Uncharted Seas slot, you do not have to worry about betting in a special game mode to enjoy that high RTP. You will be able to enjoy that 98.6% betting a minimal amount. The reason for this is because 1429 Uncharted Seas is a game from Thunderkick, a little lesser known Swedish games company who are renowned for their higher than average RTP % slots.

Blood Suckers – 98% RTP (NetEnt)

bloodsuckers slot rtp %This vampire-themed slot machine from NetEnt boasts a massive 98% RTP. For this reason, and the fact it's a "first generation" Netent slot means it's actually one of Netents most played slot. Design-wise, it does look a little classic, dare we say dated if you compare to newer slots especially Bloodsuckers 2 (which doesn't have a higher than average RTP %) but that's also the beauty of this game.

There are two bonus features in Bloodsuckers Slot which help to get this RTP very high. The first is a free spins bonus which does pop up very frequently. The second is a ‘pick bonus’. This is where you will be able to open up coffins with the potential to win some pretty sweet cash prizes. Where We Recommend To Play: JackpotVillage Casinos


Kings of Chicago – 97.8% (NetEnt)

This is a slot machine which has 5 win lines. One of the things we love about this game is the fact that it awards wins in a slightly different way to other slots.

This is because it is based around poker. This means that you win based on winning combinations from poker cards. It is a very interesting game with a high payout rate. You can’t go wrong with Kings of Chicago Slot from Netent. We believe that it's actually a little underrated!
