The 7 x 7 grid in Reactoonz 2 fills with bright, jovial aliens that tumble in from above. Wins land when clusters of 5 or more identical symbols connect horizontally or vertically; the winning group disappears and fresh symbols cascade into the gaps, creating the chance for chained wins.
Core Gameplay Elements
- Match 5+ identical aliens in a cluster.
- Only horizontal or vertical connections count (diagonals do not).
- Cascades continue until no new win forms.
- Two meters work in tandem: the Fluctometer (creates Electric Wilds) and the four-level Quantumeter (unleashes Energoon or Gargantoon wilds).
Special Features
Electric & Uncharged Wilds
- A randomly chosen one-eyed alien is fluctuating each spin. Any cluster that includes it spawns 1-3 Electric Wilds.
- Uncharged Wilds may drop in on a non-winning spin; they turn Electric when they help form a win.
Energoon & Gargantoon
- Energoon: When the Quantumeter hits 55 or 85 charges, a 2×2 or 3×3 Energoon Wild drops.
- Gargantoon: At 110 charges the famous 3 × 3 Gargantoon arrives, splits into two 2 × 2 Wilds after one cascade, then into nine 1 × 1 Wilds—each win involving it gets a 2× global multiplier.
Wild Pair Explosion
If a spin ends with ≥2 Electric Wilds and no win, they either blast away surrounding symbols or remove everything except themselves, giving one more tumble.
Pattern of Play
- Select your stake (CA$0.20 – CA$100 per spin, depending on the casino).
- Symbols tumble in.
- Cluster wins power the Fluctometer and Quantumeter simultaneously.
- Electric Wilds, Energoon and Gargantoon features trigger in sequence while cascades last.
- When no further win appears, the round ends and both meters reset.

Mobile & Regional Variants
Both titles were built in HTML5, so gameplay and features are identical on desktop and mobile. Only RTP variants and maximum-bet limits may change with jurisdiction, but mechanics are untouched.
Reactoonz 2: Technical Snapshot
- RTP: 96.20 % (default)
- Volatility: High
- Max Win: 5,083 × stake
- Min/Max Bet: CA$0.20 – CA$100
- Cluster Pays: 5+ matching symbols
- Key Modifiers: Electric Wilds, Energoon Wilds, Gargantoon Wilds, Wild Pair Explosion
There are no blanket cluster multipliers; instead, payouts scale with cluster size according to the pay-table, while 2× multipliers come from Giant Gargantoon wins at Quantumeter level 4.
Cascading Cluster Mechanics
Because wins clear space on the grid, Reactoonz 2 often strings several clusters together in one paid spin. Each winning symbol that includes an Electric Wild adds one charge to the Quantumeter; winning fluctuating symbols also top up the separate Fluctometer, which can award up to three extra Electric Wilds before resetting.
Instability
On any non-winning base spin (including the very first tumble), 4 – 6 Uncharged Wilds may drop in to kick-start potential clusters. If they help complete a win, they convert to Electric Wilds and begin charging the meters immediately.
Bankroll & Bet-Sizing Tips
Reactoonz 2 is inherently high-variance; strategies can only smooth the ride, not beat the math.
- Stake ≈ 1 % of bankroll to survive cold streaks.
- Hold your stake steady when the Quantumeter passes 50 charges—Energoon often lands within the next 3-6 cascades.
- Avoid ballooning stakes after big hits; the game’s hit frequency (~1 in 4 spins) stays fixed.
- If Gargantoon just paid out and both meters are empty, consider dropping a notch for the next dozen spins.
Why Streamers Love It
- Constant on-screen progress: filling meters builds suspense for viewers.
- Explosive reveals: a single Gargantoon drop can rocket a balance 1,000× in seconds.
- Recognisable audio: the charge-up “whoop” and Gargantoon roar have become meme-worthy.
Notable clips include Roshtein’s 11,500× win in 2019 and DeuceAce’s 9,400× in 2020—both on the original Reactoonz, but Reactoonz 2 has since eclipsed many of those records.

What Makes Reactoonz 2 a Stand-Out
- Deep, video-game-like mechanics that reward learning the meters.
- Huge single-spin potential (5,083×) without a bonus-buy cost.
- Visually distinct aliens that have spawned a mini-fandom and merch.
- Perfect for volatility-seekers who like to chase rare, screen-filling wild drops.
Who’ll love it: players who enjoy complex grid slots, chain reactions and high-risk/high-reward play.
Who should skip: fans of traditional paylines or those who prefer low-volatility games with steady returns.
Final Word
The sequel refines everything that made the 2017 classic a cult favourite: smoother visuals, an extra layer of meter strategy, and slightly higher top-end payouts. As long as you keep its high volatility in mind—and play at a casino offering the full 96.20 % RTP—Reactoonz 2 remains one of the most entertaining grid slots on the market today.
- Chain-reaction gameplay
- Multiple wild types
- Good 5083x win potential
- Complex mechanics
- No bonus-buy option
