There are no paylines. Wins form when five or more matching alien symbols connect horizontally or vertically anywhere on the grid. Winning symbols are removed, new ones cascade in, and a single spin can chain several wins in a row. Those cascades feed the Quantumeter — the charge meter that drives every feature in the game.

The Quantumeter and the Four Quantum Features

The Quantumeter sits beside the grid and charges with every winning cascade. It fills across four levels, and each level is randomly assigned one of four Quantum Features before the round begins:

• Implosion: transforms three to six random symbols into wilds and destroys all symbols adjacent to them, creating space for new symbols to cascade in.
• Alteration: selects one random one-eyed (low-value) symbol type and transforms every instance of it into a different symbol.
• Demolition: destroys all one-eyed symbols, letting a fresh wave of symbols cascade down.
• Incision: places a wild in the center of the grid and converts two diagonal lines of symbols into one randomly selected symbol type.

Each feature rewrites the board instantly, and one feature can spark further cascades that charge the next. That chain reaction — not one lucky spin — is where the 4,570x ceiling comes from.

Gargantoon: The 3x3 Wild

When all four Quantumeter levels fill during a single round, the Gargantoon lands as a 3x3 wild covering nine grid positions. On subsequent cascades it splits into two 2x2 wilds, then into nine 1x1 wilds. With that many wilds on the grid, cascades feed into each other, and this is where the game's largest payouts occur.

Fluctuation and Instability

Two smaller features run in the base game. The Fluctuation Feature triggers on non-winning spins: one one-eyed symbol type is marked as fluctuating, and if at least two appear on the grid, one transforms into a wild — potentially starting a cascade from a dead spin. The Instability Feature applies at the end of a round: if between four and eight wilds were part of the round's cascade sequence, the following spin begins with four to eight wilds placed randomly on the grid.

Reactoonz RTP, Volatility, Max Win and Bets

The Reactoonz RTP is 96.51%, slightly above the roughly 96% industry average. Volatility is high: expect stretches of quiet spins broken by sudden bursts of chained cascades, especially when Quantum Features or the Gargantoon trigger. The maximum win is 4,570x the total bet, typically requiring the Gargantoon during a cascade where high-value symbols dominate the grid — a solid ceiling for a 2017 release. Bets run from 0.20 to 100 per spin. Game specs are also published on the official Play'n GO site.

Symbols on the 7x7 Grid

Every regular symbol is a cartoon alien in one of two tiers. One-eyed aliens in pink, green, yellow, and light blue form the low-value tier: they appear often and underpin most cluster wins. Two-eyed aliens in darker colors form the high-value tier and pay significantly more per cluster. The wild is a glowing, multicolored energy cell that substitutes for all regular symbols; wilds come mainly from Quantum Features and the Instability mechanic rather than landing naturally, which makes each appearance high-impact.

Demo Play vs Real Money

The demo is mechanically identical to the real-money edition — same 96.51% RTP, volatility model, feature triggers, and payout structure — with virtual credits instead of real funds. It is a practical way to learn the cluster system and watch how cluster size affects the Quantumeter fill rate before staking real money.

Reactoonz 2 and Similar Play'n GO Slots

Reactoonz 2 is the direct sequel: the same 7x7 cluster format with additional wild mechanics layered on top of the original's framework. For more grid slots from Play'n GO, Diamond Vortex shares the cascade-plus-charge-meter structure, and Viking Runecraft pairs cluster pays with a rune-based progression system. Rise of Olympus and Moon Princess use the grid-and-meter formula in mythological settings, while Book of Dead and Legacy of Dead are the studio's best-known traditional reel slots. All are playable free at Slottomat.
