Casumo’s library typically sits between 96–97% average RTP based on our game catalogue review, and the provider breadth means you’re rarely stuck with lower-quality alternatives. The platform’s high bonus terms score (90/100 on our FruityMeter) reflects how reliably fair its wagering conditions are alongside those RTP figures. Game-level RTP is displayed on each title card, which is a transparency standard not all operators match. All published game-level RTP data and offer titles consistently above the 96% benchmark. When a slot site publishes average library RTP figures or lets you filter by RTP, that transparency is a genuine positive signal. A game with 97% RTP will, on average, return £97 for every £100 wagered over millions of rounds.
