RTP

RTP (Return to Player) is the theoretical percentage of total stakes that a casino game returns to players over a very large number of rounds — a 96% RTP slot pays back, on average, 96 cents of every euro wagered, keeping 4% as house edge.

RTP is a statistical long-run property, not a per-session promise. It is defined in the game's math model, verified by independent test labs, and certified under standards such as GLI-19 before a game can go live in regulated markets.

Operationally relevant points for operators:

• Many studios ship games in multiple RTP configurations; which versions are permitted differs by jurisdiction, and some regulators mandate minimum RTPs or public RTP disclosure.
• RTP directly shapes GGR margin: lower RTP raises hold but can hurt session length and retention.
• Your platform must serve the correct certified RTP build per market — serving the wrong configuration is a compliance breach.

Why it matters: RTP sits at the intersection of game economics and regulation. Operators need per-market RTP control and audit trails, which is why RTP management is a standard evaluation criterion for a game aggregator.
