Sugar Rush multipliers are tied to positions on the 7x7 grid, not only to individual symbols. This is why the same winning symbol can feel ordinary in one place and much more valuable when it lands on an improved cell.
How a cell becomes important
When a cluster wins, the game can mark the positions involved in that win. If later tumbles or free spins create new wins on those positions, the multiplier value can grow or apply to the payout.
Why repeat hits matter
A single cluster is useful, but repeated clusters on the same cells are what create stronger rounds. The best bonus sequences usually come from wins returning to positions that have already been improved.
Base game and free spins
In the base game, multiplier cells add extra excitement to tumbles. In free spins, they become the centre of the feature because the bonus gives more time for positions to build value.
Practical takeaway
Do not judge a Sugar Rush spin only by the first cluster. Watch where the wins land and whether the next tumble returns to those same cells. That pattern explains most of the game's bigger moments.
