Reactoonz
Reactoonz by Play'n GO is one of the most beloved grid slots in the online casino world — and at Casimo, you can dive straight into the action. Forget traditional reels; this game runs on a 7x7 grid where clusters of five or more matching aliens disappear, triggering cascading wins that can chain together in spectacular fashion. The more matches you land, the more the excitement builds.
What truly sets Reactoonz apart are its electrifying special features. The Fluctometer charges with every winning cluster, unlocking powerful Quantum Features including Implosion (which destroys surrounding symbols), Incision (cuts through rows or columns), Alteration (transforms symbols), and Demolition (wipes out all instances of a selected symbol). Fill the Gargantoon meter completely and you'll summon a colossal 3x3 wild that splits and shifts across the grid — one of the most thrilling moments in any slot game.
- Cluster pays mechanic: Match five or more identical aliens horizontally or vertically to trigger a win

Frequently Asked Questions
How does the Fluctometer work in Reactoonz?
The Fluctometer is a special meter on the left side of the grid that charges each time you land a winning cluster. As it fills through four stages, it triggers increasingly powerful Quantum Features — Implosion, Incision, Alteration, and Demolition — each one capable of dramatically boosting your winnings.
What is the Gargantoon feature in Reactoonz?
The Gargantoon is the game's most spectacular feature. When the Gargantoon meter on the right side of the grid is fully charged, a giant 3x3 wild alien appears on the reels. After each cascade with no win, it splits into smaller wilds that continue to move around the grid, giving you even more chances to hit winning combinations.
Can I play Reactoonz on mobile at Casimo?
Absolutely. Casimo is fully optimised for mobile play, meaning you can enjoy Reactoonz on smartphones and tablets without any loss of quality. The 7x7 grid adapts perfectly to smaller screens, so you get the full alien cluster-busting experience wherever you are.
