Reactoonz by Play'n GO is one of the slots we get asked about most — a 7×7 alien grid where clusters explode, Quantumeter fills and wild-charge symbols reshape...
Developed by Play'n GO, Reactoonz runs on a 7×7 grid where matching clusters of five or more identical alien symbols disappear and trigger cascades. No traditional paylines — every qualifying cluster pays. The Quantumeter on the left charges with each cascade, eventually unleashing one of four Quantum features that add wilds, transform symbols or electrify the grid. That loop of cascades feeding
the meter is what makes each round feel distinct.
Reactoonz packs its biggest moments into three interconnected mechanics. Understanding how they connect makes every session more engaging and gives you a clearer read on what the grid is about to do.
Reactoonz keeps its structure straightforward so you can focus on the cascade action rather than complex rule sets. The betting range is wide enough to suit...
Stake sizing in Reactoonz covers a broad range per spin, making it accessible whether you prefer shorter sessions or longer runs. Adjust your stake in the control bar before each spin.
Forget fixed paylines. Any group of five or more touching identical aliens pays out. Larger clusters return bigger multipliers, and a single spin can contain several qualifying clusters simultaneously.
Each consecutive cascade within one spin does not add a standard multiplier — value comes from additional clusters forming and from the Quantum features the Quantumeter releases during the sequence.
A single spin in Reactoonz can resolve quickly on a blank grid or extend into a long cascade chain. The Gargantoon phase especially stretches rounds, giving each session an unpredictable rhythm.
We display game transparency details for Reactoonz so you know what you're stepping into before the first spin. Volatility, return rate and device reach are laid out below — no ambiguity.

Picking between cluster slots and reel-based titles comes down to how you like your action to build. Here's how Reactoonz sits against sibling games you'll find in the same lobby.
Both run cluster-pay grids, but Reactoonz uses a 7×7 field with the Quantumeter mechanic, while Sweet Bonanza leans on tumble multipliers and a scatter-triggered feature round.
Gates of Olympus runs a 6×5 grid with Zeus multipliers on a feature trigger. Reactoonz generates its biggest moments through cascading cluster chains rather than a separate bonus round.
Starlight Princess uses a 6×5 grid with multiplier wilds. Reactoonz replaces that structure entirely with a cluster engine and the evolving Gargantoon symbol for its high-cap moments.
Big Bass is a traditional 5-reel, payline slot with a scatter-driven round. Reactoonz is session-long cascade action with no separate bonus state — the Quantumeter runs continuously.
Fruit Party shares the cluster-pay concept on a 7×7 grid, but its feature set is simpler. Reactoonz adds four distinct Quantum features plus the Gargantoon phase for more layered play.
Razor Shark runs nudge mechanics and a traditional reel layout. Reactoonz is a fundamentally different feel — no reels, no nudges, just a grid that collapses and rebuilds every spin.
Wanted is a 5×4 reel slot built around sticky wilds and a shootout feature. Reactoonz suits you if you prefer a continuous cascade loop rather than discrete bonus-entry moments.
These are the six things that keep Reactoonz in rotation in our lobby. From the grid architecture to the Gargantoon payoff, each highlight is specific to this game...
