What this product is
Reactoonz is the original grid slot covered by this reference. Its theme is creatures and science fiction. Sequels, Megaways editions, 1000 versions and other similarly named products are treated as separate games.
Developer and release history
The original game was released on 2017-10-23 and is attributed to Play’n GO as developer and supplier in the official product material reviewed.
Core mechanics
Layout and outcome structure: 7 × 7 grid; cluster pays
Clusters of five or more matching aliens pay. Winning clusters disappear and new symbols drop in. Flux capacitors act as wilds, oversized aliens can multiply a cluster prize, and winning clusters charge Gargantoon; a full charge triggers Quantum Leap features.
Technical parameters and configurations
The official product page confirms the 7×7 grid, cluster rule, release date and desktop/mobile screenshots. A canonical RTP is not exposed in the public page text reviewed.
Configuration scope: Original 2017 Play’n GO product page; no universal RTP claimed.
No universal RTP is stated because the official product page reviewed does not publish one.
Device evidence: The official product page publishes separate desktop and mobile screenshots.
Differences from related titles
Energoonz is described as a prequel. Reactoonz 2 is a separate sequel; later Reactoonz-branded products are also distinct.
Limits and risks
Game outcomes are random. RTP and maximum-payout figures describe a mathematical configuration over the long run and do not predict an individual session. Where a provider does not publish a universal value, this reference leaves it unstated rather than borrowing an operator-specific figure.
