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. These games offer big wins, cool features, and high return-to-player (RTP) percentages. Here's our list to help you discover the new slot machines that pay the best, and players can enjoy: Razor Ways is the undisputed champion of our list because it bridges the gap between high statistical fairness and astronomical win potential. While staples like Book of Dead cap payouts at 5,000x, Razor Ways offers a massive 50,000x limit. The game refuses to sacrifice your return for this volatility, maintaining an impressive 96.70% Return to Player. This beats almost every other heavy hitter mentioned, ensuring you chase a larger jackpot with a higher theoretical return than games like Gonzo’s Quest.
By combining the highest multiplier with the second-highest payout percentage, it remains the most logical choice for any player.
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. 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.
