Reactoonz 2 Slot Overview
Reactoonz 2 is a colourful cascading slot created by Play’n GO, featuring a 7×7 grid layout. The game centres around cluster pays, where forming groups of 5 or more identical symbols awards a win. When a winning cluster is formed, the symbols vanish, allowing new ones to cascade into the empty spaces. This process continues until no additional winning clusters appear.
How to Play Reactoonz 2
- The slot uses a 7-reel, 7-row setup with cluster pays mechanics.
- Wins are awarded for clusters of 5 or more matching symbols.
- After each win, the winning symbols are removed and new symbols cascade down, creating opportunities for multiple consecutive wins within a single round.

- Minimum bet: £0.20
- Maximum bet: £5.00
- Change your bet by clicking the plus and minus buttons at the bottom of the game screen. You can also select from five preset bet amounts.

Special Features and Mechanics
Fluctuating Symbols and Fluctometer
- At the beginning of each new round, one random one-eyed symbol is chosen to be the fluctuating symbol.
- If the fluctuating symbol forms a winning cluster, an Electric Wild is created in any position where the symbols were removed.
- The Fluctometer tracks all fluctuating symbols removed during cascades. Once full, it randomly generates 1, 2, or 3 Electric Wilds after all cascades and wins have finished.
Electric Wilds, Uncharged Wilds, and Wild Pair Explosion
- Electric Wilds substitute for other symbols to help form winning clusters and play a key role in charging the Quantumeter.
- Uncharged Wilds can appear at any time; they do not contribute to wins until they are charged by adjacent winning clusters or through the Wild Pair Explosion feature, after which they become Electric Wilds.
- If two or more Electric Wilds are left on the grid after all other features resolve, the Wild Pair Explosion is triggered. Two Electric Wilds are selected, prioritising those adjacent to each other. If adjacent, they remove all other symbols except wilds. If not adjacent, all one-eyed and two-eyed symbols between the selected wilds are removed.
Quantumeter and Its Levels
- When non-wild, one-eyed and two-eyed symbols are removed by Electric Wilds through wins or Wild Pair Explosion, the Quantumeter is charged.
- The Quantumeter has four levels, holding up to 135 charges:
- Level 1: Requires 55 charges. Awards 4 symbols of 1×1 Energoon Wilds (costs 55 charges).
- Level 2: Requires 85 charges. Awards a single 2×2 Energoon Wild (costs 30 charges).
- Level 3: Requires 110 charges. This is the fully charged state. Releases a 3×3 Gargantoon Wild.
- Level 4: Overcharged at 135 charges. Adds a x2 multiplier to all wins with Gargantoon Wilds. Only one x2 multiplier applies per winning cluster.
- After the 3×3 Gargantoon triggers a cascade, it splits into two 2×2 Gargantoon Wilds. After these trigger cascades, they split into nine 1×1 Gargantoon Wilds.
- The Quantumeter can continue charging after releasing an Energoon, but becomes disabled after Gargantoon is released.
Feature Resolution Order
- Once all cluster wins and cascades have completed, the features are triggered in the following order:
- Fluctometer effects
- Quantumeter effects
- Wild Pair Explosion
Determining Wins
Wins are based on the clusters of symbols that land on the grid. After clusters are evaluated and removed, subsequent cascades may create new clusters for additional wins in a single game round. The paytable, accessible within the game, details the symbol values and winning combinations.
