What is Reactoonz?
Reactoonz is a cluster-based slot game, meaning players win by landing groups of matching symbols rather than traditional paylines. The game features an alien theme set in a 7×7 grid. The cascading reels and quantum features increase the excitement as symbols explode and new ones drop in for multiple win chances per spin.
General Rules
The basic mechanics are simple: match 5 or more identical symbols adjacently, vertically or horizontally, to trigger wins. Each winning cluster explodes to make room for new symbols, which can lead to consecutive chain reactions that multiply wins. The game includes several special features, such as Gargantoon, which can dramatically boost payouts. Players start with bets ranging from £0.20 up to £100 per spin, making it accessible to casual players and high rollers alike.
