The share of total stakes a game returns to players over a very long run — a 96% slot pays back 96 units per 100 staked across millions of spins, not per session.
It is both a regulatory disclosure and a margin decision. Certified RTP is what auditors verify, and discrepancies between advertised and actual figures are a licence issue.
We treat RTP as provider-certified configuration, display it where regulation requires, and make sure reporting separates theoretical RTP from actual payout so operators can spot a misconfigured game.
