📊 About RTP (Return to Player) — RTP is the theoretical percentage of wagered money a slot returns to players over millions of spins. A 96% RTP means for every £100 wagered, the game theoretically returns £96. RTP is a long-term statistical average, not a session guarantee. Actual RTP figures on this page are sourced from official provider certification documents.
