The four questions readers ask most, answered in a sentence or two. Checked September 2026.
That the game keeps 50p of every £100 staked over the long run. Blackjack with basic strategy at good rules comes close; most slots keep £3 to £6 per £100.
A handful of games are published at or near 99%, often classic titles and often in a version the operator may not carry. The figure in the game’s info panel at the casino you use is the one that applies.
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.
In casino terms it is usually a house edge or a point spread: a 0.5% edge means the house keeps 50p per £100 staked; a +0.5 spread in betting means the team wins the bet with a draw.

The most frequent is reading RTP as a session figure: the Commission's page says an 85% machine should not be expected to return 85 pence per £1 during a playing session. RTP is the long-run share; volatility is the spread of a short run around it.
