Definition
Return to Player is a percentage that tells you how much of the money bet on a specific game like slots or roulette table will be paid back to players over time.
In Detail
For instance, if a game has an RTP of 95%, it is programmed to return $95 for every $100 wagered over the long run, leaving a $5 profit for the house. It is important to note that RTP is calculated over millions of cycles, so it doesn't guarantee a specific result for a single session; rather, it serves as a transparency metric to show players the long-term "fairness" and volatility of a game.
