Gameplay Overview

As you can see from the table above, the game pays in clusters. So your objective is to eliminate five or more clusters of alien symbols to win. The main game happens at the 7×7 grid, with the galaxy background. While playing on that grid, Wilds can replace any symbol, and a random symbol will fluctuate randomly during each round. We are going to discuss the fluctuation in just a bit. But for now, let’s focus on experiments. 

There is a separate experiment charger that needs 20 symbols for charging. Once it is ready to go, an experiment is chosen at random. 

These are the experiments:

  • Gamma Ray Burst Experiment – In this experiment, 7 to 9 Wilds will show up on the grid. If you land a winning Wild, it will count the symbols in its cluster before removing them. Gamma Ray Wilds will remove symbols after payout to fill the meter.
  • The Black Hole Experiment – 4-6 Wilds are added to the grid in this experiment. The clusters are counted until a win is achieved, and then the Wilds collect the adjacent symbols (horizontally, vertically, and diagonally) to energize the Experiment Charger. When three or more Wilds form a cluster, they trigger their space-tinged effect, leave the grid, and maximize overall potential.
  • The Supernova Experiment – In the Supernova experiment, 3 to 5 Wild symbols are added to the grid. Wilds that contribute to a winning cluster remain on the grid and move diagonally on each new cascade, if they don’t intersect with other symbols.

Each successful experiment will charge the Gargantoon charger, which in turn makes the Gargantoon evolve. If all 3 experiments are successful (we are talking about 40 symbols here), Gargantoonz feature is triggered. The Gargantoonz charger adds multipliers to the game. 

The feature plays in 3 steps:

1. 8 1×1 Gargantoon Wilds appear on the grid in random positions and substitute for all symbols.

2. After winning, the Gargantoon Wilds will merge into 2 2×2 Gargantoon Wilds ahead of the next cascade.


3. The 2×2 Gargantoon Wilds will then turn into a 3×3 Gargantoon.


4. After winning, the 3×3 Gargantoon Wild is removed with all winning symbols.

    Symbols Payout

    There are two categories of symbols: High-value and low-value. Two-eyed aliens pay larger amounts than one-eyed aliens, which makes them high-value symbols.

    Key Features You Need to Know

    The time for key features of the game has come. These are the things that make Gargantoonz a unique game: 

    • Cascade – The cascade mechanic removes the symbols that form winning combinations, which creates space for more combinations.
    • Fluctuate – On every spin, a one-eyed symbol will have a glow around it. If a win is formed that includes fluctuating symbols, then 1-2 Quantum Wilds will appear in any spots where a fluctuating symbol was removed.
    • Discharge – On any spin that does not create any win, it is possible that 4-8 Quantum Wilds will be added to the grid in random positions and will substitute for all symbols to form wins. It is also possible that Wilds will just land in the initial symbol drop.
