The key mathematical difference in the bonus round is that multiplier spots become "sticky" and do not reset between spins. If multipliers up to 1,024x are achieved, they remain locked on the grid for the duration of the free spins bonus. This compounding effect is the only realistic mechanic through which the top prize is approached. Retriggers are possible if an additional three to seven scatters land during the feature.
According to SlotExpanse's technical model, the bonus round triggers approximately once every 323 spins in the base game. That is a rare event even in longer sessions, and another reason to test pacing in the demo first.
