How it plays
Gigantoonz operates on a 7x7 grid with cluster pays: five or more matching symbols connected horizontally or vertically form a winning cluster. Winning symbols are removed and replaced by falling symbols from above, enabling cascades.
The defining mechanic is the Charge Meter. Each winning cluster charges a row of cells. When fully charged, those cells merge into a Gigantoon — a giant symbol block occupying 2x2, 3x3, or 4x4 grid positions. A single Gigantoon tile counts as the equivalent number of individual symbols in any cluster it touches. A 4x4 Gigantoon covering 16 cells effectively guarantees a maximum-size cluster on every spin it participates in.
Free Spins
Scatter symbols trigger the free-spins round, which begins with a pre-charged meter — meaning the first cascade of the bonus can immediately produce Gigantoon merges. The charge accumulates faster during free spins than in the base game, and multiple Gigantoons can coexist on the grid simultaneously. Overlapping Gigantoon clusters on high-symbol-value reels produce the runs toward 15,000x.
Is it worth playing?
Gigantoonz rewards understanding the charge system. Players who track meter state and recognise when a cascade is close to triggering a merge will get more from the volatility. The 7x7 grid gives the game a distinctly different texture from 5x3 payline slots — swings are compressed into fewer, larger events.
