Reactoonz Bonus Features

Reactoonz comes packed with unique theme-based bonus features, which come in the form of four random in-game perks, giant symbols with multipliers and a very lucrative wild, known as a Gargantoon Wild. Let’s take a look at how these all work.

Quantum Leap Bonus

Wins on Reactoonz will help increase the level on one of the 4 in-game bonus meters. When 1 has reached optimal charge, one of four bonus meters will randomly be added for the player to make use of. The bonus features are as follows:

  • Implosion – This transform between 3 and 6 symbols wild, while destroying all adjacent symbols.
  • Incision – This will cut a Wild in half, creating two diagonal lines through the grid. These lines will then show the same identical symbol.
  • Demolition – Destroys all one-eyed symbols and all matching symbols
  • Alteration – This will select one, one-eye symbol and will turn all matching symbols into another symbol

Gargantoon Wild Symbol

Of course, that leaves one bonus meter left, which brings in the games’ principal bonus element, The Gargantoon Wild. These can come into play after the other four bonuses have been earnt.

When in-play, these 3×3 sized symbol will come on the reels. This symbol will then divide and moves with each cascade, first splitting into two 2×2 symbols, before becoming 9 individual wilds. Possibly generating big wins as a result.

Giantoonz And Fluctuation Symbols

The game also includes two special symbols, Giantoonz and Fluctuating. When the former is in a winning combination will double any wins. While the latter could be any one-eyed symbol selected at random during each spin. If the symbol is part of a winning combination, then two wilds will be added in its place.


Wilds, as is common, will substitute all other symbols.

Reactoonz Jackpot

While there is no set jackpot, the maximum exposure on the game is pegged at 91,406 coins. A substantial potential earning.


Reactoonz offers a bang average of 96.00% RTP, duelled with high volatility. This errs on the side of longer waits but bigger rewards when they come. Owed likely to the bonus meters found within the gameplay.

Reactoonz Mobile

You can take these little alien moneymakers wherever you go, with the game fully optimized and ready for gaming on the go.
