How To Play Gigantoonz

Gigantoonz’s gameplay takes place on an 8×8 grid. To create winning combinations, 5 or more matching symbols must land in a cluster. The 2-eyed aliens award higher payouts compared to the 1-eyed alien symbols.

You can place your bets by choosing between £0.20 to £50 per spin. All the available bet values to choose from are displayed in the control bar below the reels; once you are happy with your stakes, press Play to spin the reels.

On the right, next to the reels, is the Quantumeter. Every time you form winning combinations, each symbol in the winning combination will add 1 to the Quantumeter. Once the metre reaches 100, it will activate 4 modifiers.

Gigantoonz Bonus Features

The Gigantoonz slot has a few exciting features that may keep you on your toes.

Mega Symbols

The Mega Symbols can appear in various layouts such as 2×2, 3×3, 4×4, 5×5, 6×6, and 7×7. If you form a winning combination that includes the Mega Symbol, the Mega Symbol leaves a Quantum Wild Symbol behind.

However, in terms of payouts, Mega Symbols count as a single symbol, but a random number of up to 13 will determine their cluster value.

Quantum Wild Symbols

Quantum Wilds may appear at random on any non-winning combinations. For example, you could receive between 5 and 10 Quantum Wilds. These wild symbols substitute for all the other symbols on the grid, helping you potentially form winning combinations.


Finally, the Gigantoonz slot has a Quantumeter you charge by forming winning combinations. For each symbol in a winning combination, the Quntumeter gets 1 charge. However, the mega symbols contribute their cluster value.

Once the Quantumeter reaches a certain level of charges, it will trigger one of the following four modifiers:

  • Disintegration – Only requires 25 charges, and when it is active, it selects four random symbols and removes them wherever they appear.
  • Metamorphosis – Transforms all instances of one symbol into another symbol and requires 50 charges. 
  • Radiation – Will need 75 charges and randomly adds 0-4 mega symbols and 2-5 Quantum Wilds.

Lastly, when the charge reaches 100, it will activate the Gargantoonz modifier. The Gargantoon symbol that has been sleeping all this time, perched on top of the Quantumeter, wakes up. It will:

  • Turn all mega symbols into mega Gargantoonz. Regardless of how many mega symbols are present, you will receive at least 3 sticky Gargantoonz. You will also receive 2 to 4 1×1 sized Gargantoonz.
  • Break all mega Gargantoonz symbols into bite-sized 1×1 Gargantoonz symbols. These will be removed with the cascades.

Gigantoonz RTP & Volatility

Gigantoonz has an above-average RTP rate of 96.25% and high volatility.

Theme, Graphics & Soundtrack

The Gigantoonz online slot has its 8×8 grid set against what appears to be a swirling portal in space. The background is a vibrant mix of purple, pink and blue colours. 

The symbols are alien Reactoonz with 1 eye, and some have 2 to 3 eyes. Before the game opens up to the 8×8 grid full of big-eyed aliens, you are treated to a background story about the Toonz aliens. 

The sound is an upbeat but pleasant melody.
