Reactoonz 2 Slot Game Overview
Reactoonz 2 is an online slot game created by Play'n GO, played on a 7x7 grid. The gameplay centres around cluster pays and cascading symbols, offering a range of exciting features and mechanics.
How Clusters and Cascades Work
To achieve a win in Reactoonz 2, you must land a cluster of five or more matching symbols touching horizontally or vertically. When a winning cluster is formed, those symbols are removed from the grid, and new symbols drop down to fill the empty spaces. This cascade continues as long as new clusters are formed with each drop, giving players multiple opportunities for consecutive wins in a single round.
Fluctuating Symbols and the Fluctometer
At the start of each round, one random one-eyed symbol type becomes the fluctuating symbol. If a winning cluster includes these fluctuating symbols, an ELECTRIC WILD is created at a random position among the removed symbols.
The Fluctometer, located beside the grid, collects every fluctuating symbol that is removed through wins. When the Fluctometer is full, it can award 1, 2, or 3 ELECTRIC WILDS to the grid after all current wins and cascades have finished.
Charging the Quantumeter
Every time a non-WILD, one-eyed, or two-eyed symbol is removed by an ELECTRIC WILD, either through a regular win or a WILD PAIR EXPLOSION, it adds a charge to the QUANTUMETER. The Quantumeter is essential for unlocking special features, and has four levels:
- Level 1: Needs 55 charges
- Level 2: Needs 85 charges
- Level 3: Needs 110 charges (fully charged)
- Level 4: Holds up to 135 charges (overcharged)
When the Quantumeter reaches certain charge thresholds, it unlocks specific bonuses described below. If an ENERGOON is released, the Quantumeter continues to charge, but if a GARGANTOON is triggered, further charging is disabled until the next round.
Energoon Wilds
If the Quantumeter does not reach level 3, ENERGOON WILDS are unleashed to the grid:
- At level 1 (55 charges), 4 ENERGOON WILDS, each 1x1 in size, are added at a cost of 55 charges.
- At level 2 (85 charges), a single ENERGOON WILD, sized 2x2, is released, at a cost of 30 charges.
Gargantoon Wilds and Multipliers
If the Quantumeter reaches level 3 or above, GARGANTOON WILDS enter the game:
- Level 3 (110 charges): A 3x3 GARGANTOON WILD appears on the grid. After triggering a win, it splits into two 2x2 GARGANTOON WILDS for the next cascade. Each 2x2 GARGANTOON then splits into nine 1x1 GARGANTOON WILDS after another cascade.
- Level 4 (overcharged): All wins with GARGANTOON WILDS receive a x2 multiplier, but only one x2 multiplier is applied per winning cluster.
Wild Pair Explosion Feature
If two or more ELECTRIC WILDS remain on the grid after all possible wins and feature effects have played out, the WILD PAIR EXPLOSION may activate. Two ELECTRIC WILDS are chosen, prioritising those horizontally or vertically adjacent. If the selected wilds are adjacent, all symbols except other WILDS are removed from the grid. If not adjacent, any one-eyed and two-eyed symbols between them are removed, potentially leading to new cascades and clusters.
Uncharged and Electric Wilds
Uncharged Wilds can land on the grid at any point. These are inactive until charged, meaning they cannot contribute to clusters initially. They become activated when next to a winning cluster or during a WILD PAIR EXPLOSION, at which point they transform into ELECTRIC WILDS and participate as regular WILD symbols for wins and feature triggers.
Feature Priority Order
After all winning clusters and cascade reactions are complete, features activate in the following sequence:
- Fluctometer Effects
- Quantumeter Effects
- Wild Pair Explosion
