The percentage of money wagered on a machine that is returned to players is abbreviated RTP.

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

Answer: (B)

The key idea is a game’s long-run return to players, measured as a percentage. This is called Return to Player and it represents the portion of all wagers that the game is expected to pay back to players over time. If a game has an RTP of 95%, about 95% of the money players wager is paid back as winnings on average, with the remaining 5% representing the house’s edge. This is a property of the game’s payout structure and reflects long-term behavior, not guarantees for any single session. Payout Percentage is a similar idea in some contexts but isn’t the standard term used here. Win Rate refers to how often spins result in a win, not how much money is returned on average. House Edge is the casino’s expected profit percentage, which is 100% minus the RTP.
