A slot's return to player is a designed figure taken from its paytable, not a count of spins. The Gambling Commission's own pages give the volumes it uses to check a live game against that figure, and a 10,000-session simulation shows how far a £20 session sits from it.
Read How many spins is RTP based on?: what the maths sheet says and what a session shows
The Gambling Commission publishes the formula behind its own return-to-player checks. Run that formula for a session length people actually play, rather than the volumes the regulator monitors, and the number on the paytable stops looking precise.

Read The paytable is part of the designThe four questions readers ask most, answered in a sentence or two. Checked September 2026.
Return to player is a theoretical long-run figure computed from the game’s maths model and verified over millions of simulated spins by a test lab. A single session of a few hundred spins can land far from it.
Some studios ship a game in several RTP versions and the operator chooses which to carry, within what its licence allows. The RTP in force must be shown in the game’s information panel; check it before you play.
A slot with a 97% return to player is designed to pay back £97 of every £100 staked over the long run, leaving a 3% house edge. It says nothing about any single session.
A handful of games are published at or near 99%, usually classic or low-volatility titles, and often at a version the operator may not carry. Open the game’s info panel at the casino you use; the figure there is the one that applies.
Seven weighted checks, scored from each operator’s published pages and the Gambling Commission register. Every score on this site can be re-derived from the facts in its row. Position is never sold.

Illustrative arithmetic only. RTP cannot predict a short session; every stake may be lost. Values are not a recommendation to play.
Open the game's rules or help panel before staking; under RTS 3C a GB-licensed operator must make the RTP percentage, house edge or probability information easily available before you commit to gamble. The Commission's key-terms page says the theoretical RTP is the advertised figure displayed in the player-facing rules, so the panel is the place to read it.
From How many spins is RTP based on?: what the maths sheet says and what a session shows
Look in the game's 'help' or 'how to play' pages, the artwork inside the game, or the links on the game selection pages. The RTS 3C implementation guidance names those as the acceptable places, and says the figure should be the average theoretical return to player percentage.
From How many spins is RTP based on?: what the maths sheet says and what a session shows
Every operator on the Gambling Commission's register must meet RTS 3C, so the information is a licence requirement rather than a feature of any one site. This page names no operator; the test is whether the figure is reachable before you stake.
From How many spins is RTP based on?: what the maths sheet says and what a session shows
There is no fixed threshold; the Gambling Commission states there is "no minimum RTP on a gaming machine." A percentage is more informative alongside its volatility figure, since two games sharing an RTP can behave very differently across a session.
From A 95% RTP describes millions of spins, not the one you're about to play
It means that, as an average across a very large number of plays, the game is designed to return 95% of stakes as prizes. The Commission's own guidance states RTP "is an average achieved over a significant number of game plays and not each time the gaming machine is played."
From A 95% RTP describes millions of spins, not the one you're about to play
This page does not name individual commercial titles or their current figures — theoretical RTP is disclosed per game and can differ by channel, so check that specific game's own rules or paytable disclosure rather than a third-party list.
