What Does RTP Mean?
Return to Player (RTP) is the theoretical percentage of all wagered money that a casino game pays back to players over millions of spins. A 96% RTP slot returns £96 for every £100 wagered — but over the long run, not in any single session.
RTP is a long-run mathematical average. In any single session, variance (volatility) means you could win big or lose quickly regardless of RTP. Higher RTP games are better value mathematically, but short-term results are highly unpredictable.
