Reactoonz — Play'n GO's Alien Cluster-Pay Pokie with Quantum Leap Features
Reactoonz is the pokie Play'n GO released in 2017 that proved cluster-pay pokies didn't have to use the then-standard 5-reel layout to work well. The grid is a 7×7 square; matches form on groups of 5 or more identical alien-character symbols connecting horizontally or vertically; winning clusters cascade and new symbols drop in. So far, so Sweet Bonanza. What Reactoonz added was the Quantum Leap — a progressive charge meter that fills with wins and cycles through five randomly-selected power-up features as it triggers, each of them genuinely different from the others.
The most dramatic of the Quantum Leap features is the Gargantoon — a massive 3×3 super-wild symbol that crashes onto the grid when Quantum Leap selects it, occupying nine adjacent grid positions. Successive cascades break the Gargantoon down into smaller 2×2 wild clusters, then into individual wilds, each triggering its own cascade chain. A Gargantoon landing during a hot multiplier session is where Reactoonz's 4,570× max-win outcomes originate. 96.51% RTP puts the pokie in the upper tier for the cluster-pay category; volatility is high.
At a glance
7×7 cluster-pay pokie with a five-feature Quantum Leap system. Gargantoon super-wild is the headline mechanic. 96.51% RTP is strong; max win 4,570× is moderate by modern standards but the feature variety keeps sessions engaging. Established play-style template many studios have since borrowed from.
How Reactoonz plays
Seven columns, seven rows, no paylines. Winning clusters form when 5 or more matching alien symbols connect horizontally or vertically. After a cluster pays, those symbols disappear; new aliens drop in from the top. Non-winning spins accumulate a small charge meter progress; winning clusters add more. When the meter fills, a Quantum Leap feature activates.
The paytable has one-eyed aliens (high-paying) and two-eyed aliens (low-paying) in purple, pink, blue, green, yellow and red variants. Bet range runs A$0.20 to A$100.
Bonus features
- Cluster pays (5+ matches) — 5 or more connected identical symbols form a paying cluster.
- Cascading wins — winning clusters disappear; new aliens cascade down, potentially chaining wins.
- Quantum Leap (charge meter) — fills with cascades and wins.
When full, randomly selects one of five features to activate:
- Electric Wilds — turns 3 random symbols into wilds that electrify surrounding aliens
- Fluctuation — all one-eyed aliens of a random colour convert to matching two-eyed versions (or vice versa), triggering matches
- Implosion — 3-8 random symbols transform into wilds, detonating nearby positions
- Uncharged Gargantoon — drops a 2×2 wild cluster on the grid
- Charged Gargantoon — drops a 3×3 wild super-symbol; breaks into smaller wild clusters across successive cascades
- No free spin round — Reactoonz's features all occur on the base game via Quantum Leap. No separate bonus round, no bonus buy.
Theme, graphics and sound
Candy-coloured space palette — neon pinks, cyans, and purples against a deep space backdrop. Alien characters are cartoonish and cute, with two-eyed and one-eyed variants giving each colour its own identity. Sound design uses playful electronic synth-pop with bleeps and bloops for cluster formations and escalating electronic swells for Quantum Leap triggers. Gargantoon landings use a dramatic earthquake-style effect. Distinctive visual identity that's aged well.
Mobile play
Play'n GO's HTML5 mobile port is among the best in the industry. Reactoonz runs smoothly on any phone; the 7×7 grid fits both portrait and landscape well. Quantum Leap features display clearly; cascade animations are fluid. Autoplay includes configurable limits.
