How Cluster Pays Work

Instead of traditional paylines, Reactoonz uses cluster pays. You need 5 or more matching symbols connected horizontally or vertically (not diagonally) to form a winning cluster. After each win, those symbols are removed and new ones cascade down from above, potentially creating chain reactions of multiple wins from a single spin.

Quantum Features

Every winning cascade charges the Quantum Leap meter. When fully charged, one of five quantum features is triggered:

  • Implosion: 3-6 symbols are transformed into wilds, and adjacent symbols are destroyed
  • Alteration: One random 1-cell symbol type is chosen, and all instances are transformed into another symbol
  • Demolition: All 1-cell symbols and all wilds are destroyed
  • Incision: A wild symbol is placed in the centre with two intersecting diagonal lines cutting through the grid, transforming symbols to match the same type
  • Gargantoon: A 3×3 wild is placed on the grid, then splits into 2×2, then into individual 1×1 wilds on subsequent cascades

The Gargantoon – Ultimate Feature

The Gargantoon is the most powerful feature in Reactoonz. This massive 3×3 wild symbol covers 9 positions on the grid, virtually guaranteeing a huge cluster win. After the first cascade, it splits into two 2×2 wilds, and after the next cascade, those split into nine individual 1×1 wilds. This creates three consecutive cascades with wild coverage, leading to the game's biggest payouts.

Fluctuation Feature

On any non-winning spin, the Fluctuation feature may randomly trigger. A random 1-cell symbol is highlighted, and if that symbol type is involved in a winning cluster on the next cascade, 2 wilds are placed on the grid. This helps create wins from seemingly dead spins.

Reactoonz Strategy Tips

  1. Watch the charge meter: Quantum features are triggered when the meter fills – bigger clusters charge it faster
  2. Hope for Gargantoon: The 3×3 wild is where the biggest wins hide – it's the rarest but most rewarding feature
  3. Cluster size matters: Larger clusters pay exponentially more per symbol than smaller ones
  4. Budget for high volatility: Plan for 300+ spins to experience the full range of quantum features
  5. Try Reactoonz 2: The sequel adds even more features including Energoon and Quantumeter upgrades
