Getting Started with Gigantoonz
Gigantoonz is an online slot game developed by Play'n GO. The game features a dynamic 8x8 grid and offers cascading gameplay for a unique playing experience. Players select their bet, start the game, and watch for clusters of matching symbols to secure wins.
Setting Your Bet
The game accommodates different betting preferences with options ranging from a minimum bet of £0.20 to a maximum of £5.00. Bets can be adjusted by pressing the plus or minus buttons located at the bottom of the screen. The chosen bet will apply to the current and any triggered feature rounds.
Understanding the Game Structure
Gigantoonz utilises a cluster pay mechanic on an 8x8 grid. Instead of traditional paylines, wins are created when groups of adjacent matching symbols form clusters starting from any point on the grid. Winnings are calculated and paid out according to the paytable and game rules after each round.
- Cluster Wins: Land at least 6 matching symbols in a connected group horizontally or vertically to form a win. Each symbol in a winning cluster counts toward your prize.
- Cascading Feature: Winning clusters are removed from the grid, and new symbols fall into place. Cascades continue until no further winning clusters are created.
- Combination Payouts: Multiple cluster wins in a single round are added together. Feature, bonus, and scatter wins, where available, are also added to cluster wins.
- Winning Combinations: Only the highest win per symbol combination is paid. All payouts are awarded at the end of each round.
Mega Symbols and Quantum Wilds
Throughout gameplay, special symbols and features may enhance the experience:
- Mega Symbols: These can appear in sizes from 2x2 up to 7x7 squares. Each mega symbol is assigned a random cluster value up to 13 and counts as a single symbol toward cluster wins, but the payout is determined by its cluster value. When a mega symbol forms part of a win, it leaves a WILD symbol behind on the grid. If a mega symbol cannot drop, the space is filled by regular 1x1 symbols without cluster values.
- Quantum Wilds: On rounds without wins, between 5 and 10 Quantum Wilds may be randomly added to the grid. Wilds substitute for all other symbols, increasing win potential.
The Quantumeter Features
The Quantumeter adds another layer of excitement, charging up as symbols are collected during play. Each winning symbol adds 1 charge to the Quantumeter, while mega symbols contribute their full cluster value. The Quantumeter has four distinct charge levels, holding up to a maximum of 100 charges. When no more cascades occur, the next level feature is activated.
- 25 Charges – Disintegration: Removes all instances of four randomly selected symbol types from the grid.
- 50 Charges – Metamorphosis: Randomly changes all symbols of one kind, including mega symbols, into another symbol.
- 75 Charges – Radiation: Randomly adds 0–4 mega symbols and 2–5 Quantum Wilds to the grid.
- 100 Charges – Gargantoonz: Triggered in two steps after all wins; first, all mega symbols transform into mega Gargantoonz (with a minimum of three appearing) and 2–4 single 1x1 Gargantoonz are also added. Mega Gargantoonz are not removed through wins. In the second step, mega Gargantoonz break down into regular 1x1 Gargantoonz, which can then be removed as part of winning clusters.
The Quantumeter is deactivated until all accumulated features have been played.
