Slot RTP database — every game ranked by payout rate
RTP (return to player) is the percentage of total stakes a slot pays back over millions of simulated spins. A 96.50% RTP means the game keeps £3.50 of every £100 wagered on average — it says nothing about any single session, but over time it is the single most comparable number between games.
The catch most players miss: 3 of the 18 slots below exist in multiple RTP versions. Providers such as Pragmatic Play ship the same game at several certified RTP levels, and each operator chooses which version to license — so the "same" slot can pay 96.50% at one casino and 94.03% at another. We flag every slot where we have lower variants on record, with the full range in the table. If a slot is flagged, open the in-game information panel at your casino and check the figure before you play.
Methodology: figures come from provider spec sheets as recorded in our database on 11 July 2026. The RTP column shows the highest published version. Click a column heading to re-sort; every slot links to its full review.
