Highest Paying Slots Online

To ensure you have the best chance at winning when you play online slots, there are a couple of things you need to understand and look out for. One of the first things to grasp is a slot game's RTP%. This is essential in understanding so you can pick the slots which offer the highest RTP%. The term ‘RTP %’ is what online casinos use to refer to the percentage of all the wagered money that an online slot machine will pay back to the player over time. So basically, exactly how much of the money that’s put in by players will be paid back to the player over time?

For example, if a slot has an RTP of 95%, it would pay back £95 of every £100 that are put in. But, be sure to know that the RTP is calculated over a long period of time to include the highs and lows (variance). Of course, the higher the RTP % that the slot has, the more positive the odds are for you, meaning the bigger the chance that you will win something. To know what RTP % is considered good and high, here’s a guide:

How To Check a Slots RTP %

Most online slots will tell you the RTP % in the paytable or you'll find the information out on the developers own website. Those companies which don’t offer these statistics – we don’t recommend playing their slots, as you can never be too sure what the payback is, and if they're not publishing you have to ask yourselves why. No matter if you love to play high variance or low variance slots, games from suppliers including Netent, Thunderkick, and Microgaming usually offer more competitive and higher RTP % which is why they feature in our top playing slots list above.

No Slot Guarantees Any Profit

Playing online slots that offer higher RTP% rates doesn't mean that you have a guaranteed chance of winning when you play. The closer the RTP comes to 100%, the better odds you have of actually beating the casino, but you are gambling and nothing is guaranteed of course. That's why it is advisable to play online slots that have the best RTP % and the above slots offer just that.
