Return to player, or RTP, is the single most quoted statistic in online slots, and one of the most misunderstood. In simple terms, RTP is the percentage of all wagered money a slot is designed to pay back to players over an extended period. A game listed at 96% RTP, for example, returns an average of £96 for every £100 staked, with the remaining £4 representing the house edge. It is a long-term theoretical figure, not a promise for any individual session, but it remains the clearest guide to how generous a game is likely to be.

Under United Kingdom Gambling Commission rules, licensed operators must publish RTP information clearly, so players can compare games before spending a penny. Most modern video slots sit between 94% and 97%, though the gap between the top and bottom of that range is meaningful. Over thousands of spins, a 96.5% game and a 94% game behave very differently, and choosing wisely is one of the few genuinely player-controlled variables in slot play.
It is worth separating RTP from volatility, because the two are often confused. RTP describes the average return over time, while volatility describes how that return is delivered, frequent small wins or rare large ones. A high-RTP slot with high volatility can still produce long losing streaks. Understanding both figures together gives a far more accurate picture than either statistic alone.
How RTP Is Calculated and Where to Find It
RTP figures are produced through millions of simulated spins during game testing, typically by independent laboratories such as eCOGRA, GLI or BMM Testlabs. These results are then verified before a slot reaches UK-licensed casinos. Because the calculation is based on enormous sample sizes, the published percentage is a reliable long-term average, even though short sessions can swing wildly in either direction.
Finding the figure is straightforward. Nearly every slot has an information or “i” button on its loading screen or within the paytable, and the RTP is usually displayed there alongside the game rules. UK-licensed casino lobbies increasingly filter games by RTP, and dedicated slot review sites publish verified figures for thousands of titles. If a game does not state its RTP anywhere, that alone is a reason for caution.
Watch for variable RTP versions. Some providers release the same slot with different return settings, for example, 96%, 94% and even 92%, and operators choose which version to host. A game that looks identical in screenshots can pay noticeably less depending on the casino. Checking the in-game information panel at the specific site you play at is the only way to confirm which version you are actually spinning.
Bear in mind that jackpot contributions can reduce the base-game RTP. On progressive slots, a slice of every stake feeds the prize pool, so the playable RTP may sit lower while the overall figure includes the jackpot. The published number should account for this, but it is always worth reading the small print.
Which Slots Offer the Highest Payouts?
Several well-known titles consistently publish RTP figures at or above 96.5%. Mega Joker has historically topped charts at around 99% in its optimal mode, while Blood Suckers sits near 98% and Jackpot 6000 around 98.9%. Among more mainstream releases, NetEnt’s classic slots and a number of low-volatility titles routinely clear the 96% mark. These games suit players who prioritise steady returns over headline jackpots.
As a rule of thumb for UK players, anything at 96% or above is solid, 95% is acceptable, and below 94% is best avoided unless the game offers something genuinely special. The table below summarises how to read the range:
| RTP Band | Assessment | Typical Examples |
|---|---|---|
| 97% and above | Excellent | Mega Joker, Blood Suckers |
| 96%-96.9% | Good | Most leading video slots |
| 94%-95.9% | Average | Many branded and megaways titles |
| Below 94% | Poor value | Some high-margin releases |
High RTP does not guarantee a profitable session, and no strategy changes the underlying maths. What it does offer is better long-term value per spin. Combined with sensible staking, bonus awareness and time limits, choosing higher-RTP games is a rational habit rather than a shortcut to wins. Play for entertainment, set a budget in pounds before you start, and treat every session as paid-for fun.
