Reactoonz takes place in a quirky corner of the cosmos, hosted by a cast of cute and colorful one-eyed and two-eyed aliens. The game grid is set against a deep space background, with the giant Gargantoon sleeping peacefully on the side. The graphics are bright, bubbly, and full of personality, a signature of Play’n GO’s design. Animations are constant and energetic, with aliens dropping, zapping, and exploding on the grid. The soundtrack is a playful and futuristic electronic tune that perfectly matches the high-energy gameplay of this high RTP slot.

  • Regular Symbols: The symbols are eight different alien creatures. The four smaller, one-eyed aliens are the low-pays, while the four larger, two-eyed aliens are the high-pays. The pink two-eyed alien is the most valuable. Wins are formed by landing a cluster of 5 or more matching symbols that are connected horizontally or vertically.
  • Special Symbols:
    • Wild Symbol: A swirling vortex of energy acts as the Wild, created by certain features. It substitutes for all other symbols.

Playing Reactoonz is an adventure in itself. First, select your bet size from the panel below the grid. Then, hit the spin button to drop a new set of 49 aliens. Winning clusters will disappear, causing a cascade of new symbols to fall into place. Understanding the chain reactions is key, so playing the free slot machine demo is highly recommended for new players. This mobile slot is a visual treat on any device.

The game is all about charging the meter to unleash powerful features.

  • Cascading Wins: Every winning cluster is removed, allowing new symbols to drop in, potentially creating a long chain of wins from a single spin.
  • Quantum Leap Meter: Every symbol in a winning cluster contributes to charging the five-level Quantum Leap meter. Each filled level queues up one of four random features:
    • Imprecision: A Wild symbol appears in the center and destroys all surrounding symbols.
    • Alteration: One random low-paying symbol is transformed into another symbol.
    • Demolition: All low-paying symbols are destroyed and removed from the grid.
    • Incision: A Wild is placed in the center, creating two diagonal lines of the same symbol.
  • Gargantoon Feature: If all five meters are charged, the mighty Gargantoon is unleashed! First, a giant 3×3 Wild symbol is added to the grid. After any cascades, it splits into two 2×2 Wilds. Finally, it splits again into nine individual 1×1 Wilds, creating an epic finale with massive win potential.

RTP: The default RTP for Reactoonz is an excellent 96.51%, which is well above the industry average. Players should always be mindful that Play’n GO allows operators to use lower RTP settings, so it’s wise to check before playing.

Volatility: Reactoonz is a high volatility game. This means that players can experience long periods with smaller wins while they try to charge the meter. However, when the features, especially the Gargantoon, are triggered, the payouts can be astronomical. It’s the ultimate high-risk, high-reward experience.


Reactoonz is not just a slot; it’s a phenomenon. Its perfectly balanced chaos of cascading wins and charging meters creates one of the most engaging and replayable experiences in the online casino world. The anticipation of filling that final meter and unleashing the Gargantoon is a thrill that few other games can match. It’s a true masterpiece of slot design and an absolute must-play for any fan of grid slots or innovative bonus features. Join the Reactoonz and get ready for a reaction!
