Game Overview
Gigantoonz is an online slot developed by Play'n GO, featuring an 8x8 grid with cascading reels. This game focuses on cluster pays mechanics, where wins are awarded for symbol clusters rather than traditional paylines. The minimum bet per round is £0.20, and the maximum bet is £5.00.
How to Play
- Wins are formed by getting clusters of 6 or more matching symbols connected vertically or horizontally with no gaps between them.
- When a winning cluster is achieved, it is removed from the grid, and new symbols fall into place, potentially creating further wins. Cascades continue until no additional clusters are formed.
- Only the highest value cluster win per combination is paid out, and all winnings in a round are combined.
- Winning clusters can start at any position on the grid.
Betting Controls
- Bets are adjusted using the plus or minus buttons located at the bottom of the game screen. You can select your desired stake before starting each round.
- Once your bet is set, press the START button or use the spacebar to begin a game round. The outcome and any prizes are determined by the symbols shown, in accordance with the paytable.
Mega Symbol Feature
- Mega symbols can appear in sizes ranging from 2x2 up to 7x7, each with a randomised cluster value of up to 13.
- Mega symbols are counted as a single symbol for cluster wins, but use their specific cluster value to calculate prizes.
- Each winning mega symbol leaves a WILD symbol on the grid.
- If a mega symbol is unable to descend further, the spaces below will be filled with individual 1x1 symbols without added cluster value.
Wilds and Quantum Features
- On non-winning rounds, between 5 and 10 Quantum Wilds can appear randomly on the grid, increasing chances for future wins.
- Wild symbols substitute for any other symbol.
- Gargantoon Wilds are introduced through the Quantumeter feature.
The Quantumeter and Charge Features
- Each symbol in a winning cluster adds 1 charge to the Quantumeter. Mega symbols contribute their exact cluster value to the Quantumeter.
- The Quantumeter holds up to 100 charges, tracking progress towards powerful features. It progresses through four levels:
- 25 charges: Disintegration
- 50 charges: Metamorphosis
- 75 charges: Radiation
- 100 charges: Gargantoonz!
- Once no further cascades occur, the next available charge feature will trigger. The Quantumeter becomes inactive if all its features have been played in a round.
Quantumeter Feature Descriptions
- Disintegration: Removes all instances of four randomly chosen symbols from the grid.
- Metamorphosis: Randomly selects one symbol type and transforms all its instances (including mega symbols) into a new symbol.
- Radiation: Randomly adds between 0 and 4 mega symbols and between 2 and 5 Quantum Wilds to the grid.
- Gargantoonz: This feature activates in two phases after wins resolve. First, all mega symbols transform into mega Gargantoonz (with a minimum of three appearing) and 2–4 additional 1x1 Gargantoonz are added. Mega Gargantoonz remain on the grid even after wins. Second, these break into 1x1 Gargantoonz, which are then cleared through normal gameplay.
Payouts and Paytable
Prizes are paid according to the number and value of clusters formed, as detailed in the in-game paytable. All winning combinations and feature wins, including those from Bonus and Scatter symbols (if applicable), are added together at the end of the round. Free Spin features, where applicable, use the same bet amount as the round that triggered them. The current bet cannot be changed during an active game round.
Game Information and Fairness

- If a round is not completed within 90 days, unresolved bets will be voided.
- Any malfunction during play voids all pays and plays for the affected round.
- The slot’s RTP is displayed within the game.
