What Is Slot RTP?

RTP refers to the (theoretical) return to player that a slot game is programmed to pay out over time. It is measured as a percentage of the money wagered on the slot machine. A typical slot will operate at an RTP of around 96%. That means, for every £100 wagered on the game, £96 will be paid out in prizes and £4 retained by the casino operator (an amount referred to as the house edge).

It is important to remember that RTP is a theoretical value. It is not absolute and will vary from one session to another. If it didn’t, gambling on a slot would be very predictable, and no one would play as they would always lose! The RTP will vary as some players will win back much more than 96% of their money whilst others will win back much less. But overall, over millions of spins, the game should hit its programmed RTP value.

Should I Play High RTP Slots?

RTP is one of three factors that determine the payout pattern of a slot game. The others are variance and top payout potential. A game with a high RTP is likely to return more of your money than a low RTP game, but this figure does not tell you everything you need to know to understand the maths of the game and whether it is the right slot for you.

Variance is also important because it will tell you how far from the RTP a game will deviate in its payout pattern. Low variance slots do not vary much in their pattern so you can expect to win roughly the advertised RTP in each session. High variance slots vary greatly and their unpredictability makes them high risk. A 96% RTP high variance slot may give one player astronomical wins in a short period, whilst another player may lose all their money very quickly.

Payout potential is also important because it tells you the maximum amount you can win in one spin, regardless of the RTP or the variance of the game.

So, to answer the question, RTP is a good indicator of the style of slot you are playing, and playing high RTP slots will give you more money back on your stakes. But keep in mind that variance and payout potential will also affect your experience too.

Best Payout Slot Games in the UK

Playing slots with high RTP rates is a useful strategy, not only for new customers but also for seasoned UK players of online casinos. They generally have a lot of exciting features to allow for win multipliers, matching symbols, wild symbols, expanding symbols or a mystery prize that can all happen at completely random times allowing for huge wins for lucky players depending on the slot. Generally speaking, these higher hit frequency games have more ways to win and high payouts on high volatility slots with some of the biggest wins in casinos.

The higher the RTP the better and the best value slots with more ways to win will give a greater return to player rate and so they are highly recommended. Some top picks for the best payout slot with the highest RTP rates are Book of 99 with a whopping 99% RTP, Blood Suckers, Starmania, Zeus Lightning and the White Rabbit slot with the White Rabbit Megaways feature which is a great win feature that increases chances for players to win and get a great payout.

These high payout slots are great options to play high RTP games for veteran and new players that are great fun!
