Gigantoonz Symbols & Payouts

The symbols

The Gigantoonz slot machine grid consists of eight reels and eight rows. The toonz themselves represent the game’s symbols. The higher ones are the larger ones, paying in the order of red, pink, green, yellow, and blue.

The lower paying symbols of the Gigantoonz online slot are smaller toonz which descend from blue to purple, brown, green, and mustard. Quantum wilds are represented by orbs and Gargantoon Wilds are a white and brown toon.

There are no set paylines on the Gigantoonz online slot. Instead, you’ll receive prizes when collecting clusters of six or more matching symbols in adjacent positions (horizontally and/or vertically). Only the highest cluster win pays, but if you land more than one cluster during the same spin, the prizes will be added up and paid out as one prize.

Min/max bet, autoplay option

You can choose bets between 0.20 and 100.00 on the Gigantoonz slot machine. You can either spin manually or opt for the autospin, which allows you to play 10, 20, 50, 75, or 100 consecutive spins. You’ll also be able to set your loss and win limits along with whether you’d like to stop the autoplay when achieving a win. To end the autoplay early, simply click on the stop button which replaces the autoplay one during the feature.


The Gigantoonz online slot has 96.25% RTP.


We found the Gigantoonz slot machine to be highly volatile.

Maximum win

You can win up to 4,000x your bet on the Gigantoonz online slot. This means 400,000 coins when playing with a maximum stake. There is no jackpot feature within the game.

Gigantoonz is simple but fun and interactive

You’ll find the Gigantoonz slot machine to be similar to the other slots in this Play’n GO series of games. The symbols are larger, and the RTP remains pretty standard. High volatility gives you less frequent but higher wins. You can win up to 4,000x your stake, which even with a low stake of 0.20 is quite the prize.

Game Features

Gigantoonz slot features


Wild Symbol features in Gigantoonz online slot
Wild Symbols

The Gigantoonz online slot has two types of wilds:

  • Quantum Wilds: 5 to 10 of these may randomly drop during a non-winning spin, taking the place of already existing symbols
  • Gargantoon Wilds: These only appear through the Quantumeter

In either case, the wild substitutes for any symbol within the game to help complete or enhance winning combinations.

Mega Symbols in Gigantoonz online slot

Mega Symbols

Mega Symbols may fall in blocks of 2×3, 4×4, 5×5, 6×6, or 7×7 symbol sizes, each with a cluster size as high as 13x on them. While they count as one symbol when forming a cluster, the cluster number is used as a value when determining the size of the prize.

Tumbling Reels

Winning symbols disappear from the reels each time a cluster is formed. This allows for new symbols to fall down, potentially creating new clusters.


The Quantumenter sits to the right of the Gigantoonz slot machine. You’ll fill this by collecting clusters from initial wins or with the tumble feature. 

There are four achievable levels:

  • Disintegration (25 symbols): Removes all instances of 4 symbols which are selected at random.
  • Metamorphosis (50 symbols): Transforms all instances of one randomly selected symbol into another. This includes any instances of Mega Symbols.
  • Radiation (75 symbols): Adds 1 – 4 Mega Symbols and 2 – 5 Quantum Wilds in random positions on the grid.
  • Gargantoonz (100 symbols): This feature has two parts. In the first, all Mega Symbols turn into Gargantoonz. A minimum of three appear, regardless of how many are within the grid. You’ll see an additional 2 – 4 Gargantoonz appear on the grid after that. Once done, you’ll be paid for any wins achieved. During the second part, the Mega Gargantoonz break down into individual symbols and are removed normally.

Cook up some electric wins with the Gigantoonz features

I like what Play’n GO has done with the Gigantoonz online slot. While there is a lack of free spins round, the game offers other exciting features which make the game both unique and engaging. You’ve got your random Quantum wilds that magically appear during a non-winning spin. Collect clusters to activate the special features of the Quantumeter which will transform, remove, and add symbols to help you win. And let’s not forget the Mega Symbols which add up to 13x symbols to your cluster’s prize.

While the game doesn’t have traditional special features, the Gigantoonz slot offers unique features such as random wilds which activate during losing spins and the Quantumeter, which has four levels of modifiers.
