Understanding RTP: What It Means for Greek Players

1. What is RTP and How Does It Work?

RTP is expressed as a percentage and calculated over thousands or millions of spins. For example, a slot with 96% RTP will, in theory, return €96 for every €100 wagered over time. However, RTP doesn’t guarantee individual wins—it simply reflects the game’s overall payout structure.
