Reactoonz Free Demo & Review
Reactoonz is Play'n GO's loud little alien grid slot: a 7x7 Cluster Pays game with cascading symbols, Quantum features, wilds, and a top win of 4,570x. The verified RTP is 96.51%, volatility is high, and the usual bet range runs from $0.20 to $100 per spin. There are no paylines and no free spins round; the action comes from clusters of 5+ matching symbols, chain reactions, and the Gargantoon wild feature. Ontario players should use the demo first, then play for real money only at casinos registered with AGCO and operating through iGaming Ontario.

Who Should Play Reactoonz
01
Reactoonz pays for 5 or more matching symbols touching horizontally or vertically, while diagonal groups alone do not pay.
02
Every paid cluster vanishes and refills from above, which lets one spin run through several cascades before it ends.
03
The Quantum system is driven by winning symbols and cascades, not by scatter symbols or a separate free-spins trigger.
04
Gargantoon is the biggest wild feature in the game, but it still plays inside the same 7x7 cascade round.

How to Play Reactoonz
Set your spin size
Choose your total wager before spinning. Reactoonz uses a fixed 7x7 grid and Cluster Pays system, so changing the stake changes the money value of wins, not the number of paylines or active positions.
Match alien clusters
Press spin to fill the 49-position grid with Reactoonz symbols. Wins form when 5 or more matching aliens touch horizontally or vertically; diagonal-only groups do not count.
Charge the Quantum features
Winning clusters disappear and new symbols drop in, creating cascades. Paid symbols feed the Quantum meter, which can queue features such as Implosion, Alteration, Demolition, Incision, and the larger Gargantoon wild event.
Let the reaction finish
Each cascade and feature resolves before the round closes. The game adds all cluster wins, wild-assisted wins, and feature results from that spin, then pays the final total when no more winning clusters or queued effects remain.
