Reactoonz 2 Review: Our Verdict
UnionSlots rating: 7.5/10. Reactoonz 2 suits players who enjoy busy grids where every cascade feeds a meter. The Fluctometer and Quantumeter give small wins a purpose, the Gargantoon stages are genuinely exciting, and the 5,083x max win is a solid ceiling. The catch is complexity and swing: there are several kinds of wild to learn, the top Quantumeter stages need long cascade chains, and high volatility means plenty of spins end with little or nothing.
Pros
- A deep, connected feature set: fluctuating symbols, Electric Wilds and two meters all feed each other.
- The Gargantoon arrives as a 3×3 wild and breaks into smaller wilds over the following cascades.
- A 5,083x max win, the same figure in every database that lists one.
Cons
- Uncharged, Electric, Energoon and Gargantoon wilds take time to learn.
- The 3×3 Gargantoon needs 110 Quantumeter charges, so it is hard to reach.
- UK casinos can run lower RTP versions than the 96.20% default.

How Reactoonz 2 Works
Symbols drop onto a 7×7 grid, and a win needs a cluster of five or more matching symbols touching horizontally or vertically. Winning clusters disappear and new symbols fall into the gaps, so one paid spin can chain several cascades. Uncharged Wilds can appear on the grid and become Electric Wilds when a win forms next to them. Electric Wilds substitute for paying symbols and can zap symbols off the grid, and every non-wild symbol they remove charges the Quantumeter.
Fluctometer and Electric Wilds
At the start of each spin, one of the one-eyed Reactoonz is picked at random to fluctuate. When a fluctuating symbol is part of a win, an Electric Wild fills one of the emptied spaces and the Fluctometer gains a charge. Once it reaches its maximum of 11 charges, it adds between one and three Electric Wilds to the grid at random. When two or more Electric Wilds are left on the grid, they can team up in a Wild Pair Explosion that blasts symbols off the grid.
Quantumeter, Energoon and Gargantoon
The Quantumeter fills as Electric Wilds remove symbols, and it has four stages. At 55 charges, four Energoon wilds join the grid, and the second stage adds a single 2×2 Energoon wild. At 110 charges the 3×3 Gargantoon Wild arrives; after a cascade it breaks into two 2×2 wilds, then into nine 1×1 wilds. At 135 charges the Gargantoon is released with a x2 multiplier. Reaching the top stages takes a long chain of cascades, which is why results swing so much from spin to spin.
RTP, Volatility and What to Expect
Reactoonz 2 has a 96.20% RTP at its default setting. UK casinos can run lower RTP versions; check the game’s info screen. Volatility is high, so expect plenty of short sequences that stop after a cascade or two, with the bigger results depending on chaining enough wins to push the Quantumeter towards its Gargantoon stages. The 5,083x max win gives real upside, but it is a game to play at a stake you are comfortable losing over a long run of quiet spins.
