Return To Player is therefore basically the polar opposite of House Edge.
Using a simple example, if you were to make a thousand one euro bets on a slot machine on with a theoretical Slot RTP of 96.01%, all other things being equal you would expect to get a return of €960.10 in wins from your staked €1,000.
RTP also known as the Return to Player is the phrase casinos and casino games makers use to describe the long term theoretical expected payback percentage from all wagers on a slot machine, video poker machine, video lottery terminal (VLT), pokies or any other form of gambling with a set calculated house edge.
