What is Return to Player (RTP)?
RTP is the inverse of the house edge. It represents the percentage of all the wagered money that a specific game will pay back to players over time. If a slot's RTP is 96%, casino it means for every $100 wagered, it will theoretically return $96 to the player pool over its lifetime.
