Reactoonz highlights

  • Innovative cluster pays slot with an above-average RTP rate
  • Highly volatile game with a fixed jackpot of 4,570x your bet
  • Lots of different bonus features on offer

Reactoonz is one of the most innovative and absorbing slots on the market. The reels are vibrant, and features such as cluster pays, cascading symbols, and vanishing symbols make the gameplay reminiscent of Tetris. There are lots of bonus features, the RTP rate is above average, and it offers the chance to win a large fixed jackpot.

How to play Reactoonz slots

Reactoonz is an online slot played on a 7×7 grid. The game eschews traditional paylines in favor of a cluster pays mechanic. Just spin the reels, and you will win if five or more symbols are clustered together on the grid.

Game rules

You can click the information logo when playing Reactoonz to browse the rules. This information will break down the various features: Instability, Quantum Leap, Quantum features, Giantoonz, and Fluctuation. You will then see a pay table that displays the value assigned to each symbol.

How to read paylines

The Reactoonz slot game does not feature the standard paylines found on most slots. Instead, you will win if five or more symbols are clustered together in any direction on the grid after you spin the reels.

The grid is large, so you can potentially end up with 15 or more of the same symbols clustered together. If so, you will earn a substantial payout. For example, if 15+ of the pink monsters are clustered up on the grid, you will earn 1,200x your bet amount.

Ways to spin

The minimum bet on the Reactoonz slot is $0.20, and the maximum is $100. Use the plus and minus signs to flick through the various bet size options, and then click one to select your stake. You can then hit the green button to spin the reels.

The yellow button gives you the chance to autoplay. You can select 10, 20, 50, 75, or 100 spins. It allows you to stop the autoplay on any win if a single win exceeds a particular amount or if your balance increases or decreases by a certain amount. The RTP of the slot is 96.51%, but it is a highly volatile game, so it offers larger and less regular payouts than low-volatility slots.

How Reactoonz slot game works

Reactoonz features eight different symbols. The grid is always busy, as the symbols can expand to cover multiple reels, or they can implode.

Any symbols that form a winning cluster will disappear from the grid. New symbols will then cascade down onto the reels, offering additional opportunities to form winning combinations.

Reactoonz symbols

The Reactoonz slot machine symbols are all jelly-like aliens. Four of them have a single eye, and the other four have two eyes. The aliens with two eyes offer larger payouts. These are the different multipliers you will receive.

Special symbols: Giantoonz and Fluctuation

If four matching symbols form a square shape on the grid, they will become Giantoonz. That means the symbols will expand, covering multiple reels, and wins will be doubled in any winning combinations that feature Giantoonz.

A single one-eyed alien symbol will be marked as the fluctuating symbol on each spin. If any of the marked symbols form part of a winning combination, they will leave two wild symbols behind when they disappear from the grid. The wild symbols substitute for any other symbols, which will make it easier for you to form winning clusters when new symbols drop onto the grid.

Reactoonz slot bonus rounds

Reactoonz does not offer traditional slot bonus rounds, but you can trigger lots of different bonus features during the base game.

Instability Feature

If your initial spin does not result in a win, there is a chance that the Instability feature will come into play. If so, the Gargantoon can drop between four and eight wild symbols onto the grid. That gives you the chance to land winning clusters.

Quantum Leap

A random Quantum feature will be added to the queue if you win on 25 or more symbols. There are four Quantum features, which can be lined up at any time.

Quantum features

These are the four Quantum features:

  • Implosion | This feature transforms between three and six symbols into wilds, while also destroying any adjacent symbols.
  • Demolition | Destroys all one-eyed symbols and matching symbols. That leaves just two-eyed symbols, which offer higher multipliers.
  • Incision | Cuts a wild symbol into the center of the grid and creates two intersecting diagonal lines through it. Both lines show the same random symbol.
  • Alteration | Chooses a one-eyed symbol at random, and all matching symbols turn into a different symbol.

All of these features are designed to improve your chances of forming clusters.
