Start with the grid, not a payline count
Reactoonz is described by its provider as a grid slot rather than a fixed-line game. The 7×7 board holds the symbols. A cluster needs five or more matching aliens; when it wins, those symbols are removed and replacements drop from above.
Cascades make one round a sequence
A single result can contain more than one evaluation. First a qualifying cluster clears. The board then refills, and the new arrangement is checked again. A later cascade is a new outcome within that round, not evidence that a future spin is more likely to win.
A cascade example, step by step
A cluster of five matching symbols clears from the 7×7 grid. The remaining symbols drop into the open cells, then the new arrangement is checked for another cluster. That sequence explains one possible round structure; it does not imply that the refill will create another match.
Gargantoon adds a second progression
Winning clusters also charge the meter for Gargantoon. A full meter starts a Quantum Leap, where the large character becomes wild and a chain of up to five features can follow. The published description identifies the feature sequence, but does not provide a session forecast.

Figures not published on the source page
The Play'n GO page checked describes the rules but does not publish a numeric RTP or volatility label for this release. Those fields are left out rather than borrowed from another version; any published RTP is a theoretical long-run model, not a forecast for a session.
