2. Understand RTP
RTP stands for Return to Player. It’s the percentage of wagered money you can expect back over a large number of spins. The higher the percentage, the more frequently you are expected to win. If you clock a game with a 96% RTP, for example, you might expect to win 96 times out of 100 spins.

5. Consider game volatility
Slot volatility is a bit like waiting for a bus – sometimes they all come at once, and sometimes it seems to take a while. Remember, high RTP doesn’t mean you’ll win more often. Some high RTP slots have higher volatility and others have a low volatility.

What is RTP in slots?
RTP (Return to Player) is a percentage that shows how much of your wagered money a slot will pay back over time. For example, a high RTP slot with 97% RTP will theoretically return £97 for every £100 spent. But remember, this figure is calculated over thousands of spins, so take it with a pinch of salt. It’s definitely not a promise – it’s more of a guide to help you choose wisely.
Why are high RTP slots important?
High RTP slots are important because they can offer better returns compared to low RTP games. Keep an eye on that percentage figure as a higher number generally gives you a higher payout rate. If you want your money to last longer, high RTP slots might be your best bet.
Are high RTP slots safe to play?
Absolutely, and you can rest easy knowing that the best high RTP slots are tested and verified. Trusted authorities like the UK Gambling Commission oversee the UK gambling industry to keep providers in check and ensure you get a fair deal. All slots have Random Number Generators (RNGs) too. This function is tested by independent companies like eCOGRA to keep everything above board and to boot any funny business out of the gambling industry.
RTP vs. Slot Volatility/Variance: What is the difference?
RTP shows how much a game pays back over time, while volatility (or variance) tells you how often you might win. High RTP and low volatility slots give more frequent, smaller payouts. High RTP, high volatility slots can provide less frequent wins but possibly bigger rewards. Consider your slot preference, choose wisely and check out our comparison below for more details.
| RTP | Volatility | Explanation |
|---|---|---|
| High RTP | Low Volatility | Frequent, smaller payouts over time, offering steady returns with lower risk in gambling. |
| High RTP | High Volatility | Larger but infrequent payouts, leading to higher risk but potentially bigger rewards over time. |
Progressive Jackpots and RTP
Progressive jackpots are like playing the lottery while on a slot machine – the prize will keep growing until it’s won. But here’s the catch. Progressive slots often have lower RTP because a portion of each spin contributes to the overall jackpot. Think of it like paying tax, but more fun. Instead of your local council filling in potholes with the money, there’s a chance you could win it all. You can play some high RTP UK slots with progressive jackpots online, including the following.
| Progressive Jackpot Slot | RTP | Play at |
|---|---|---|
| Mega Fortune | 96.6% | Casumo |
