How to play Reactoonz 2
Bet range: 0.20–100
- Wins form when five or more matching symbols connect in a cluster.
- The Fluctometer fills as its tracked symbol wins, then releases Electric Wilds onto the grid.
- Electric Wilds charge the Quantumeter by removing non-wild symbols, unlocking Energoon and Gargantoon wilds at set thresholds.
- After all features resolve, the Wild Pair Explosion activates if two or more Electric Wilds remain.
Bonus features
Multipliers
Charging the Quantumeter to Level 4 (135 charges) adds an x2 multiplier to wins, including Gargantoon wilds.
Fluctometer
one random one-eyed symbol fluctuates each spin; when it wins, an Electric Wild appears and charges the Fluctometer, which adds 1-3 Electric Wilds to the grid when full.
Quantumeter
each non-wild symbol removed by an Electric Wild adds one charge; 55 charges release four 1x1 Energoon wilds, 85 a 2x2 Energoon wild, 110 a 3x3 Gargantoon wild and 135 adds an x2 multiplier.
Gargantoon Wild
the 3x3 Gargantoon splits into two 2x2 Gargantoon wilds after a cascade, and those split into nine 1x1 Gargantoon wilds after another cascade; the Quantumeter is disabled once a Gargantoon is released.
Wild Pair Explosion
when two or more Electric Wilds remain after all features, adjacent wilds remove all non-wild symbols, while non-adjacent wilds destroy the symbols between and around them; removed symbols still charge the Quantumeter.
The Quantumeter has four charge thresholds that each release a different wild type or effect. Once a Gargantoon is released, the Quantumeter pauses, and the Gargantoon splits across cascades — first into two 2x2 wilds, then into nine 1x1 wilds.
