Play’n GO comes through with mega spoils in the form of Reactoonz, an alien-themed online slot game that uses a cascading game engine. This intergalactic adventure is packed with quirky characters and electrifying wins. Here’s a comprehensive review of Reactoonz.

Game Overview

Reactoonz is among the jackpot slots variety and is played on a 7×7 grid instead of the traditional reels, and it features the clusters pays engine. In order to form winning combinations, players must land five or more matching symbols as long as they are touching either horizontally and/or vertically. 

The betting range starts at $0.20 and goes up to $100 per spin. Your aim is to round up energetic extra-terrestrials. The return to player (RTP) for Reactoonz is 96.51%, and it’s a high-variance slot game. When it comes to the max win, players can stand the chance of winning an impressive 4,570x their stake. 

How To Play

The premise of Reactoonz is as exciting as it gets. Working on a cluster pay engine, the game creates a chain of wins when a cluster of five or more similar symbols connect horizontally or vertically. A cluster win removes the winning symbols and replaces them with new ones cascading from the top, promising a continuous stream of fun and rewards. 

In Reactoonz, four matching normal symbols adjacent to each other in a square shape automatically form Giantoonz. Wins are doubled in any winning combinations that Giantoonz is a part of. Click on the yellow info icon to locate the paytable. Here, you’ll see how much each symbol is worth. 


Through its visuals, Reactoonz takes you to a parallel universe and has a cute, alien theme. There are amazing cartoon-style graphics with a dark blue background. It’s a colorful feast with highly animated aliens dropping from the sky to fill the 7×7 grid. The symbols on the reels include four-lower-paying aliens, four higher-paying aliens, and a vortex wild. The highest-value symbol is the pink alien that gives you 750x your stake for five across a payline. 

In terms of audio, prepare for space-age tunes that will surely add to the overall space adventure. 


Of course, the cluster pays mechanic makes this a standout online slot game. In addition to the cluster pays, Reactoonz also features an autoplay function that allows players to choose between 10 and 100 spins. These slot features make the gameplay more engaging and exciting.

Bonuses and Jackpots

The Reactoonz slot depends on the cascading reel engine to allow for more and more wins. Each win charges the Quantum Leap meters, leading to five more slot bonus features. The base game has two other features, too, which means that Reactoonz has a total of nine bonus features. Here’s a closer look at some of the features in Reactoonz.

Quantum Leap Feature

When players land a win, it’ll increase the five Quantum Leap charges meters one by one. When a meter is charged, one of the quantum features is randomly added to the queue. These features include: 

  • Implosion feature: 3–6 symbols are transformed into wilds, with adjacent slot symbols also being destroyed. 
  • Alteration feature: One random low-value symbol is chosen, with all instances of that symbol transforming into another symbol. 
  • Demotion feature: All low-value symbols are destroyed and removed from the grid.
  • Incision feature: A wild is cut into the center and creates two intersecting diagonal lines through the grid. This feature will then display the same randomly chosen symbol.

When all five meters are fully charged, the Gargantoon feature is added to the queue. The Gargantoon adds 3×3 wild symbols randomly to the grid. The Gargantoon divides to become two 2×2 wilds with each cascade. With the game’s next cascade, it divides again into nine 1×1 wilds. If this doesn’t lead to a win, one randomly triggered quantum feature is triggered.
