Gigantoonz
The Gigantoonz slot features a lively science lab theme with quirky alien symbols and animated reactions across a grid. Colourful graphics and playful sound effects create a light-hearted atmosphere, while cluster symbols and a unique grid format add to the visual appeal of this imaginative slot experience.
Game Overview
Gigantoonz is an online slot game developed by Play'n GO. The game is played on an 8x8 grid and features cascading symbols. Bets range from £0.20 to £5.00 per round.
How Wins Are Achieved
Wins are awarded by forming clusters of 6 or more adjacent matching symbols. Symbols must connect either horizontally or vertically, with no gaps between them. Clusters can begin from any position on the grid. When multiple clusters are formed in a single round, all their winnings are combined. Only the highest win is paid for each winning symbol combination, according to the paytable and game rules. All winnings, including those from features and bonuses, are added together at the conclusion of a game round.
Cascading Mechanic
Each time a cluster win is formed, the winning symbols are removed, and new symbols drop down to fill the empty spaces on the grid. Cascading continues until no further winning clusters are formed within the same round.
Mega Symbols
- Mega symbols can appear with sizes of 2x2, 3x3, 4x4, 5x5, 6x6, or 7x7.
- Each mega symbol is assigned a random cluster value of up to 13.
- Although a mega symbol counts as a single symbol for winning clusters, its cluster value determines the payout.
- When a mega symbol is part of a win, it leaves a WILD symbol in its place.
- If a mega symbol cannot drop to fill a gap beneath it, 1x1 versions without cluster values fill the space instead.
Wild Symbols
- On non-winning rounds, 5 to 10 QUANTUM WILDS may be added randomly to the grid.
- GARGANTOON WILDS appear through the activation of the QUANTUMETER feature.
- WILD symbols substitute for all other symbols on the grid.
QUANTUMETER Feature
- Each winning symbol contributes 1 charge to the QUANTUMETER. Mega symbols add their full cluster value as charges.
- The QUANTUMETER holds up to 100 charges and is divided into four levels:
- 25 charges: DISINTEGRATION – Removes all instances of four randomly chosen symbols from the grid.
- 50 charges: METAMORPHOSIS – All instances of one randomly selected symbol, including mega symbols, are transformed into another symbol.
- 75 charges: RADIATION – Between 0 to 4 mega symbols and 2 to 5 QUANTUM WILDS are added in random positions.
- 100 charges: GARGANTOONZ! – This feature is triggered in two steps:
- All existing mega symbols become mega GARGANTOONZ (minimum of 3), alongside 2 to 4 1x1 GARGANTOONZ. These mega GARGANTOONZ cannot be removed through wins during the first step.
- Next, mega GARGANTOONZ break apart into 1x1 GARGANTOONZ, which can then be removed in the usual way during subsequent wins.
- After all cascades complete and if the QUANTUMETER has a charge, the next feature is triggered. The QUANTUMETER remains inactive once all features for a round have been played.
