Think of it as the opposite of the house edge: the higher the RTP, the more favorable the odds are for the player.įor instance, if a slot machine has an RTP of 95%, it suggests that for every $100 you wager, you can expect to get back $95 over a longer duration. It's a percentage that describes the amount of money a slot machine will pay back to its players over an extended period. One of the most important terms you'll come across when discussing slot machine odds is RTP or Return to Player.
