Live RTP version and the game rules
Three SCATTER on reels 1, 3 and 5 start the Standard Respins, but nobody can tell when that will happen. How often the bonus round comes is not known in advance. The result of one session is random whatever the RTP, so a long run of quiet spins says nothing about the next spin.
Every spin on the 5x4 grid runs on one of three RTP versions, and only the game rules show which version is live here. The reels never reveal it, so no spin tells the player which version applies.
Each Respins payout adds up the five reel multipliers and multiplies that sum by the bet, and the result stops at the ceiling. The maximum win is a ceiling reached very rarely, so it should not shape expectations. Nothing on the screen shows how close a session is to that limit.
