Inside Reactoonz 2: the evolution of Play'n GO's cult classic
Stacked against the original, this sequel (released 1 October 2020) replaces single-meter progression with a multi-tier charge. You now fill the Fluctometer and the Quantumeter at the same time. That dual-meter engine gives long sessions a pulse: cascades feed wilds, wilds feed the Quantumeter, and the grid keeps reacting. Free play is the cleanest way to learn how the two meters talk before you spin for real money.
Alien aesthetic: visuals, animations, and soundscape
Against a cosmic blue backdrop, the 7×7 grid hosts animated Toonz that blink, bounce, and celebrate cluster hits. The Fluctometer and Quantumeter glow as they fill, then throw lightning across the board. An upbeat sci-fi track ramps in tempo as cascades chain together.
Specs: RTP, volatility, and max win
Default RTP is 96.20%, though operators can offer lower ranges such as 94.20% or 91.20%. High volatility favors intense feature chains over frequent small hits. Strict bankroll management helps you stay in the seat while building toward the 5,088× max win.
Grid dynamics: how cluster pays and cascades work
Core play is Cluster Pays plus cascading drops. A few steps get you onto the board:
- Select bet amount: stakes range from $0.20 to $100.00 per spin.
- Consult the paytable: one-eyed Toonz, two-eyed premiums, and Wild types.
- Spin the 7×7 grid: five or more matching symbols that touch horizontally or vertically pay.
- Watch the cascade: winning aliens pop, remaining symbols fall, new icons drop from above.
- Ride the chain: reactions continue automatically until no new cluster forms from that wager.
Fluctometer
A one-eyed alien fluctuates. Cluster wins with it leave Electric Wilds and charge the meter.
Quantumeter
Electric Wild wins fill it for Energoonz, then the 3×3 Gargantoon that splits across the grid.

Symbols, meters, and Gargantoon
Low-value one-eyed Toonz (yellow, green, red, purple) return 0.1× to 10× for clusters of 5 to 15+. High-value two-eyed Toonz (blue, orange, green, pink) pay more; the pink two-eyed Toon tops the table at up to 500× for a 15+ cluster. Uncharged Wilds land inert on cascades and become Electric Wilds when they sit next to a winning cluster. Electric Wilds substitute for paying symbols and charge the Quantumeter.
Each base spin, the Fluctometer picks one low-pay one-eyed symbol. Winning clusters of that symbol leave Electric Wilds behind. Eleven fluctuating symbols fill the meter and spawn 1–3 extra Electric Wilds. The Fluctometer stays live through cascades until the Quantumeter hits Level 3.
Electric Wilds in winning clusters feed a four-level Quantumeter: 55 charges spawn four 1×1 Energoonz; 85 drops a 2×2 Energoon; 110 summons the 3×3 Mega Gargantoon; 135 overcharges a 2× multiplier on Gargantoon wins. After a 3×3 win it splits into two 2×2 wilds, then nine 1×1 wilds. If cascades stop with two or more Electric Wilds still on the grid, Pair Wild Explosion clears symbols around or between them without charging meters. HTML5 scales the 7×7 board for iOS and Android browsers — no app.

Smart play: tips for safe and responsible gaming
High-volatility grid slots need discipline. Set deposit and loss limits before a session. Size a bankroll that can absorb dry spells — charging the Quantumeter to Level 3 takes consecutive cascades. Take breaks, and treat the game as paid entertainment, not income.
Dual meters, Electric Wilds, and staged Gargantoon releases give grid fans a sequel with real depth. Use the free demo on this page to learn the quantum loop before wagering real money.
Player reviews
Notes from sessions on the alien grid.
★★★★★ 4.6/5
Gargantoon at 110 charges is the whole show. Dual meters take patience, then the 3×3 splits and the board actually moves. I stay on $1 spins for the 96.20% default.
★★★★☆ 4.3/5
Toonz read clean in portrait. Sci-fi bed ramps on cascade chains. Electric Wilds lighting the Quantumeter is the visual I wait for.
★★★★☆ 4.2/5
Fluctometer plus Quantumeter is a lot on a first night. Pair Wild Explosion saved a dead cascade for me. Check the paytable RTP — not every lobby is 96.20%.
★★★☆☆ 3.8/5
High vol is honest: long quiet stretches, then a 2× Gargantoon overcharge. No classic free-spin round. The wilds still carry the bonus.
★★★★★ 4.5/5
HTML5 on Android Chrome, one-handed portrait, meters slide beside the 7×7. No extra app. 5,088× is the ceiling, not a habit.
FAQ
How does the Quantumeter differ from the Fluctometer?
The Fluctometer collects fluctuating low-pay symbols to spawn Electric Wilds, whereas the Quantumeter charges via Electric Wild wins to summon Energoonz and Gargantoon Wilds.
How do you trigger the 3x3 Mega Gargantoon Wild?
You must collect at least 110 charges in the Quantumeter during a single spin sequence to reach Level 3, which drops the 3x3 Gargantoon onto the grid.
Is the max win in Reactoonz 2 lower than the original slot?
No, the Reactoonz 2 max win is 5,088x your stake, which exceeds the original Reactoonz win cap of 4,570x.
How does the 3x3 Gargantoon Wild divide into smaller Wilds as cascade wins continue?
After the 3x3 Gargantoon triggers a win and cascades, it splits into two 2x2 Gargantoon Wilds. Following another cascade win, those split into nine individual 1x1 Gargantoon Wilds.
Is there a limit to how many Electric Wilds can exist on the 7x7 grid simultaneously?
While up to 11 Electric Wilds can populate the grid through Fluctometer spawns and conversions, there is no hard cap preventing additional Wilds from dropping via natural cascades.
