Know the limits before the first spin
Scatter symbols can land anywhere on the grid and open the free spins, yet when they land stays unknown before you play. Each spin is random, so how often the bonus round comes cannot be known in advance. The result of one session is random whatever the RTP, and a high RTP does not promise a win in any single session.
Every spin on the 7x7 grid follows the one RTP version the game runs, and that version appears only in the game rules. The versions sit within a narrow band, so reading the rules matters before comparing one with another.
Tumbling symbols and growing multipliers can build toward the top prize, but the maximum win of Sugar Rush Super Scatter is a ceiling reached very rarely. Reading the figures table helps you see that ceiling, yet it does not show how often a spin gets close to it.
