Return to Player (RTP) is a term used to describe the percentage of all money paid into the game that is paid out in winnings over a period of time.

For example, if the RTP for a game is 90%, and all players for that one game wager a total of £100, the total amount of winnings paid out will be, on average, £90. It is important to remember the RTP is an average expected return across the game over a large number of game plays, and not a guaranteed return for each player.

As a result, if a game displays a 90% RTP, you should not expect to win 90 pence for every £1 you spend.
