Reactoonz
What Is Reactoonz?
Reactoonz is a 7×7 cluster pays slot by Play’n GO, released in October 2017. It abandoned traditional paylines entirely in favour of an alien-themed grid where 5 or more matching symbols connected horizontally or vertically form a win. Winning symbols disappear and new ones cascade from above — creating chain reactions on a single spin.
The true magic is the Quantumeter — a charge meter on the left that fills as symbols are removed from the grid. As it charges through 4 levels, increasingly powerful Quantum Features unlock. Reach the final level and the Gargantoon arrives: a 3×3 wild that splits into 2×2, then nine individual wilds across cascades.
Released back in 2017, Reactoonz instantly became a worldwide hit and remains one of the most-played Play’n GO games ever among Australian casino players — its unique blend of arcade energy and feature depth is unmatched.
How to Play Reactoonz
Quantum Features & Gargantoon
Transforms 3–6 low-value symbols into wilds while destroying all symbols adjacent to them. Creates instant cluster opportunities across the grid.
Picks one random 1-eye symbol type and converts all matching symbols on the grid into another symbol type — potentially forming massive clusters.
Destroys all 1-eye symbols on the entire grid at once — leaving only the higher-value 2-eye symbols for subsequent clusters and cascades.
Places a wild in the centre of the grid and draws two diagonal lines of matching symbols through it — creating massive instant clusters from one symbol.

Tips for Playing Reactoonz in Australia
Budget for 200+ Spins
Rated 10/10 volatility by Play’n GO. Reaching Gargantoon requires significant Quantumeter charging. Plan for at least 200 spins at your chosen bet before expecting big returns.
Watch the Quantumeter
Each Quantum level unlocking is a meaningful event. Level 3 (Demolition) clears all 1-eye symbols — that’s when the grid gets lucrative. Level 4 + Gargantoon is your target.
Use Demo First
The layered feature system (cascades → Quantumeter → Quantum Features → Gargantoon) takes several sessions to understand fully. Demo mode at Royal Reels is free, no account needed.
Instability = Free Help
On any non-winning spin, Instability randomly drops 4–8 free wilds onto the grid. This acts as a safety net against dead spins and can suddenly revive a losing run. It’s not triggered by anything — just luck.
Play’n GO themselves rate this 10 out of 10 volatility. Long cold runs punctuated by explosive cascade chains. The Gargantoon when it hits is the payoff for patience.
