Reactoonz 2 from Play’n GO is a sequel to the online slots game and studio’s cult classic Reactoonz – where cluster pays replace traditional paylines and every spin can trigger a chain of reactions. The game expands on the original’s alien-themed world with new power meters, Gargantoon multipliers, and four interlinked bonus features that keep the energy levels high throughout each round.
With its cartoon design and cascading wins, Reactoonz 2 is as much about watching the grid come alive as it is about chasing multipliers. High volatility means it can take time to land big combinations – but when the features align, the rewards can be significant.
There are no paylines and no fixed bonuses – Reactoonz 2 runs entirely on chain reactions and power meter progress. All outcomes are determined by a certified Random Number Generator (RNG).
Winning clusters charge the Quantum Meter to unlock four levels of special features:
After each winning combination, symbols are removed and new ones drop from above. This can trigger several wins within a single spin.
Two types of wilds – Electric and Uncharged – help complete clusters and keep chain reactions flowing. When Electric Wilds connect, they can reactivate the meter for additional features.
When the meter is fully charged, Energoons or the giant Gargantoon drop onto the grid, turning sections into wild symbols and potentially leading to the highest wins in the game.

The grid is filled with multicoloured alien symbols of varying values. Larger, one-eyed Reactoons act as premium symbols, while smaller two-eyed ones represent lower values.
Electric Wilds substitute for adjacent symbols to form clusters. When two Electric Wilds connect, they create energy bursts that charge the Quantum Meter again.
Energoons appear mid-round to replace symbols with wilds, while Gargantoon Wilds arrive fully charged and split into smaller versions as the round progresses. These features combine for big chain reactions.
Every win removes symbols and adds new ones, continuing until no new clusters form – creating the possibility for lengthy win chains.

Reactoonz 2 keeps everything that made the original popular while dialing up the chaos. With its layered Quantum Meter system and chain-reaction wins, this slot offers constant movement and a sense of build-up that few games match. The vivid animation and light-hearted tone make it as entertaining to watch as it is to play.

Reactoonz 2 builds on the original with a dual Quantum Meter, new types of wilds and extra bonus stages. The core mechanic remains cluster pays on a 7 × 7 grid, but features like Electric Wilds and Energoon replacements add more depth and chain potential. Visually, it’s brighter and faster paced, but still follows the same chaotic energy that made the first game so popular.
The RTP for Reactoonz 2 is set at 96.20 %. This figure represents the average return to player over a large number of spins.
