Bonus features include mega symbols (colossal symbols), multipliers, bonus meter, cluster wins, and quantum wilds that help you unlock the game’s biggest payouts.

Symbols & Paytable

The Gigantoonz paytable below indicates how much you can win on a base game spin by landing clusters of at least six matching symbols:

Symbol 6-30+ Symbols
Yellow Alien 0.10-5.00
Green Alien 0.10-5.00

Mega Symbols

Mega symbols can land in Gigantoonz, and they can be 2x2, 3x3, 4x4, 5x5, 6x6, or 7x7 in size. Each mega symbol counts as a single symbol in a winning cluster, but its value is determined by a random value up to 13. What’s more, when the mega symbols leave the grid, they leave behind an extra wild that can contribute to subsequent wins.

Quantum Wilds

In the base game, non-winning spins may trigger the quantum wilds feature, in which 5-10 of these random wilds are added to the grid, substituting for all regular symbols in the process.


Each contributing symbol to a cluster is collected in the Quauntumeter every time you land a winning combination. Moreover, mega symbols that land add cluster value to the meter. There are 100 charges in the meter, and four modifiers can be triggered at different phases:

  • Phase 1 (25 charges) = disintegration. This removes four randomly selected symbols from the grid.

  • Phase 2 (50 charges) = metamorphosis. This transforms all instances of one random symbol into another and can include mega symbols.

  • Phase 3 (75 charges) = radiation. This adds 1-4 mega symbols and 2-5 quantum wilds to the grid.

  • Phase 4 (100 charges) = Gargantoonz. Here, the Gargantoonz symbol appears, which transforms all mega symbols into the Gargantoonz and at least three of these land. What’s more, at least two 1x1-sized Gargantoonz also appear. Mega symbols then break down into regular Gargantoonz, which are then removed from the grid.
