What does RTP mean on casino games?

RTP is an acronym for return to player percentage. The average RTP on most online slots is 96.20% and is considered a very good payout. This doesn't that any given time the player will win back such amount, but is calculated on a global figure. Some games might have a high volatility and a lower rtp. This however, doesn't mean that the slot will pay out less, but might higher wins.
