What makes Reactoonz different
Reactoonz is a 7×7 grid pokie by Play’n GO, released in 2017. It uses cluster pays — wins require groups of 5 or more matching symbols touching horizontally or vertically — rather than traditional paylines.
The game’s cast of one-eyed alien creatures fills the grid, and winning clusters are removed in an avalanche, allowing new symbols to fall and chain reactions to form.
The Quantum meter
The central mechanic is the Quantum meter, a charge bar on the left side of the reels that fills whenever a cluster win occurs. Each charge level activates a random feature:
- Fluctuation — 1–6 random Wilds are placed on the grid before the spin resolves
- Implosion — non-winning symbols surrounding a Wild are destroyed, expanding the Wild’s reach
- Alteration — one lower-paying symbol type is converted to a higher-paying type across all reels
- Demolition — all symbols of the lowest-paying type currently on the grid are destroyed
When the meter reaches maximum charge, the Gargantoon Wild activates.
The Gargantoon
The Gargantoon is a 3×3 Wild that enters the grid and triggers a re-spin. After each re-spin, it shrinks by one size (3×3 → 2×2 → 1×1), with each size triggering another re-spin. If matching symbols form around the Gargantoon during these re-spins, wins can cascade across the full grid.
RTP and volatility
Play’n GO publishes 96.51% RTP. Reactoonz is high-volatility — the grid mechanic and Quantum meter mean most value is concentrated in sessions where multiple features activate in sequence. Long stretches without significant wins are normal.
What it costs per hour
At NZ$0.40 per spin and 400 spins per hour: NZ$160 wagered × 3.49% house edge = approximately NZ$5.60 expected loss per hour.
### Q: What is the difference between Reactoonz and Reactoonz 2?
A: Reactoonz 2 (2020) adds a 5-level Quantum Leap meter, new alien characters, and modified feature triggers. The core cluster-pays mechanic on a 7×7 grid is the same. Reactoonz 2 has a slightly different volatility profile and updated visual design. Both versions are available at the casinos listed on this page.
### Q: How does cluster pays work compared to paylines?
A: In cluster pays, any group of 5 or more matching symbols that are horizontally or vertically adjacent counts as a win — regardless of their position on the grid. There are no fixed payline patterns. Larger clusters pay more, and a single cluster of 15+ symbols pays significantly more than a cluster of 5.
### Q: What triggers the Quantum features?
A: Each cluster win charges the Quantum meter. The meter has 4 charge levels; reaching each level triggers the corresponding feature (Fluctuation, Implosion, Alteration, Demolition). Reaching full charge triggers the Gargantoon. A single spin with multiple cascading wins can trigger several features in sequence.
Playing Reactoonz at NZ casinos
Reactoonz returns 96.51% over the long run — well above the 78% minimum return required at NZ land-based pokies venues. At the NZ$0.20 minimum bet, the 3.49% house edge produces an expected hourly loss of approximately NZ$2.79 at 400 spins. At the NZ$100 maximum bet that rises to approximately NZ$1,396. The 7×7 grid and cluster pays mechanic mean winning combinations form across a large number of symbol positions on every spin, giving the base game a more active feel than narrower payline structures at the same volatility level.
High volatility means Reactoonz sessions are event-driven rather than steady. The Quantum meter charges with every cluster win, which means active base game play accelerates toward feature activation — but the features themselves vary widely in value. Fluctuation adds a handful of random Wilds; the Gargantoon trigger can cascade across the full 7×7 grid with sustained re-spins. Sessions where the Quantum meter charges quickly and the Gargantoon triggers with strong symbol coverage produce the game’s significant outcomes. Sessions where cluster wins are small and infrequent produce little. The avalanche mechanic creates natural engagement through chain reaction potential on any spin.
The 4,570x maximum win requires optimal Gargantoon Wild placement during re-spins with high-value cluster formations covering the grid — a statistical outlier across millions of spins. At NZ$0.20 per spin it represents NZ$914; at NZ$100 it represents NZ$457,000. Expected hourly cost at the NZ$0.20 minimum is approximately NZ$2.79; at NZ$0.40 approximately NZ$5.58.

Q: What is the maximum win on Reactoonz?
A: The stated maximum win is 4,570x your stake. At NZ$0.20 per spin this would be NZ$914.00. Maximum win figures represent the theoretical ceiling under optimal conditions — they are statistical outliers that occur rarely across millions of spins, not typical session outcomes.
