How it plays
Reactoonz is Play'n GO's alien grid slot, released on 23 October 2017 as the follow-up to Energoonz. It plays on a 7×7 grid, and a win needs a cluster of five or more matching aliens; bigger clusters pay more.
Aliens in a winning cluster are removed and new ones drop in from above, so one spin can pay several times. Flux capacitors act as wilds, and oversized aliens can multiply the prize when they are part of a winning cluster.
Gargantoon
Gargantoon waits on his base next to the grid, and every winning cluster charges him with energy. Once he is fully charged he grows and makes a Quantum Leap onto the middle of the grid, and his chain reaction can release up to five features that create more winning clusters.
