Why RTP matters
When the reels spin, the Return‑to‑Player percentage is the silent engine that decides whether a session feels like a sprint or a marathon. High‑RTP slots are the ones that whisper “stay longer, win more” to the player’s subconscious, and outside GamStop you get the full buffet without the usual filters.
