How Reactoonz works

Reactoonz replaces reels and paylines with a 7x7 grid. A payout is awarded for a cluster of five or more matching symbols, and larger clusters pay more.

Cascades. Symbols in a paying cluster are removed and replaced by new symbols dropping in from above, so a single spin can produce several payouts in a row.

Wilds and oversized symbols. Flux capacitor symbols act as wilds. Oversized alien symbols can multiply the prize when they form part of a paying cluster.

Gargantoon. Every paying cluster transfers energy to the Gargantoon character waiting on his base. When fully charged, Gargantoon grows and makes a Quantum Leap onto the middle of the grid, where he acts as a wild and sets off a chain reaction of up to five further features.

Context. Play'n GO describes Reactoonz as a follow-up to its earlier grid slot Energoonz.
