Budget each spin without counting on a payout
Each spin fills the 7x7 grid, and the scatters decide whether the free spins start. How often that bonus round comes is not known in advance. The result of one session is random, whatever the RTP. Long dry runs and quick hits both leave the next spin as open as the first.
Every cluster of five or more matching symbols pays, yet the RTP version you play is shown only in the game rules. Check that line before the first spin, because the reels themselves never show which version is running.
On the special reels, Multiplier Spots keep building through the whole free spins round and can lift a win well above the base game. The maximum win is a ceiling that is reached very rarely, so treat it as a limit, not an expectation.
