Return to Player (RTP) is a term used in online casinos and gambling sites that refers to the average amount of money a game gives back to its players. It's usually expressed as a percentage, which is calculated by dividing the total amount of money paid out by the total amount of money wagered.
This percentage gives an indication of how often a game pays out and how generous it is. Generally, games with higher RTP percentages tend to payout more frequently than those with lower percentages.
For example, if a game has an RTP of 95%, then for every €100 wagered, the players can expect to receive roughly €95 back in winnings over the long run. It's important to note that RTP does not guarantee a player will win. Rather, it is simply an indication of the likely payout rate over time. With this in mind, players should always be sure to understand the rules and chances of winning before placing any bets.
