What is the expected percentage of money wagered on a gambling machine that is returned to players as winnings over time called?

• A. Payout Percentage
• B. Win Rate
• C. Return to Player (RTP)
• D. House Edge

Answer: (C)

The main idea here is the long-run share of money wagered that a gambling machine pays back to players. That measure is called Return to Player, and it’s expressed as a percentage. It represents, on average, how much of the wagers the machine returns over many spins. For example, an RTP of 96% means that, over a very large number of bets, about 96 units are paid back for every 100 units wagered. The rest stays with the house as profit. This concept is different from the win rate on a single spin, which measures how often a spin yields any win rather than how much money is returned on average. The house edge is simply 100% minus the RTP, representing the casino’s long-run advantage. Payout Percentage is sometimes used interchangeably with RTP, but RTP is the standard term for the long-run return.
