Understanding RTP
Return to Player explained without marketing fluff: long-run average, sample variance, and how to read published percentages.

Definition
RTP is the theoretical percentage of wagered money a game returns to players over an infinite horizon under its model. A 99% RTP game returns $99 per $100 wagered on average — not per session.
Misconceptions
RTP is not a guarantee for 100 spins.
Two games with identical RTP can feel completely different if variance differs.
