Gigantoonz Slot Game Overview

Cluster wins are awarded for adjacent symbol combinations, according to the information in the paytable and game rules. When winning on multiple clusters in a single game round, all winnings are added together. 

All winnings from Features (such as Free Spins), Bonus Game and/or Scatters (if applicable) are also added to cluster wins. All winning combinations are paid out at the end of a game round. Free Spin features are played with the same bet as the game round that triggered the feature - unless otherwise stated. 

The bet cannot be changed during a currently running game round. Please refer to the game rules for more information. Winning combinations only pay when symbols are connected horizontally or vertically and without any gaps. 

Winning combinations can start from any point on the grid. Only the highest win is paid per winning symbol combination.

Gigantoonz Game Rules

GIGANTOONZ is an 8x8 cascading video slot game.

Wins are achieved by getting 6 or more symbols in clusters. These are removed and new symbols fill up the grid. Cascades continue until no more wins can be created.

Mega symbols may appear in 2x2, 3x3, 4x4, 5x5, 6x6, 7x7 symbol sizes. Each mega symbol has a cluster value randomized up to 13. When forming wins, a mega symbol counts as a single symbol, but its cluster value is used when determining the payout of the winning cluster. Each winning mega symbol leaves a WILD on the grid. If a mega symbol cannot drop down, it fills up the space with its own 1x1 versions, without cluster values.

On any non-winning round, 5 to 10 QUANTUM WILDS may be added randomly. GARGANTOON WILDS may appear through the QUANTUMETER only. WILDS substitute for all symbols!

Each winning symbol counts as one charge towards the QUANTUMETER, but mega symbols add their cluster values. QUANTUMETER has 4 charge levels and holds up to 100 charges. Collect 25 charges for DISINTEGRATION, 50 for METAMORPHOSIS, 75 for RADIATION, and 100 for GARGANTOONZ! When there are no more cascades, the next charge feature in line triggers. QUANTUMETER inactivates for the round if all features are played out.

DISINTEGRATION removes all instances of 4 randomly selected symbols. METAMORPHOSIS randomly transforms all instances of one symbol into a different symbol, including mega symbols. RADIATION adds 0-4 mega symbols and 2-5 QUANTUM WILDS randomly. GARGANTOONZ plays out in 2 steps, one by one after wins conclude. Firstly, all mega symbols turn into mega GARGANTOONZ. At least 3 mega GARGANTOONZ appear, regardless of how many mega symbols are present. Additionally, 2-4 1x1 GARGANTOONZ appear. Mega GARGANTOONZ are not removed with wins. Secondly, the mega GARGANTOONZ break down into 1x1 GARGANTOONZ, which are removed normally.

The average RTP is 87.25%. RTP is achieved through participation.

Bets are selected using the bet buttons in the bottom part of the game. Click the plus and minus buttons to change the bet one step at a time. To start the round, click START. When the symbols land, the symbols displayed determine your prize according to the paytable.


  • Changing Your Bet - Click any of the five bet buttons to select a bet or use the plus or minus buttons to increase or decrease the bet by one step.
  • Paytable - Toggles the display of the paytable.
  • Start / Spacebar - Starts the game round with the currently selected bet. Press Spin to begin.
  • Auto adjust bet - Automatically reduces the total bet when starting a new spin, if the balance is too low to initiate a spin at the current bet level. The reduced total bet selected will be the highest possible bet and will be lower than the selected bet size when autospins was initiated. The bet will be decreased only and will not return to it's original amount following any wins that would allow the initiating bet size to be resumed.
