Interestingly, different states have thresholds they must legally abide by when it comes to RTP. For example, if you were to play a game with an RTP of 97%, theoretically, if you wagered $100, then you should expect to have around $97 returned to you throughout the game.
Different games will boast different RTP percentages. Also known as “return to player” or even a “payout percentage”, the RTP tells you how much you will receive back from a specific casino game on average over time.
