RTP stands for ‘Return to Player’ and is a term that describes the potential chance that a player has of winning a prize when playing online slots. A higher RTP means that the slot has a higher chance of paying out, while a lower RTP means you have less chance of winning. Say, for example, a slot has an RTP of 95%. This means in theory that it should pay out £95 for every £100 played. If you put £100 into an online slot with an RTP of 95%, there is no guarantee that you’ll win back £95. We prioritise sportsbooks and online casino sites that offer fair, clearly explained promotions with reasonable wagering terms. Our team also ensures that there are bonuses covering both sports and casino games so that you can unlock rewards no matter what you’re wagering on. Some platforms, like Midnite, offer welcome packages for both types of betting.

You should view RTP as a guide – in essence, if you play a slot with an RTP of 95%, you’re more likely to win than on a slot with an RTP of 85%. The RTP percentage is an average calculated over a long period of plays, not each time the game or slot is played. The RTP percentage is generally measured between 10,000 and 100,000 plays or more to accommodate for bonuses and randomly activated features.
