Gigantoonz
Gigantoonz is a slot game that features quirky alien creatures on a colourful grid, where players form clusters to trigger cascading reactions and unique Quantum features, including transforming symbols and special wilds, creating an engaging and dynamic gameplay experience filled with lively animations and sound effects.
Introduction to Gigantoonz Slot
Gigantoonz is an 8x8 grid video slot developed by Play'n GO. The game uses cascading mechanics and features cluster pays, creating an engaging grid slot experience. It is designed for both new and experienced players looking to explore unique game features and mechanics.
Basic Game Structure
- Provider: Play'n GO
- Reels: 8x8 grid
- Minimum bet: £0.20
- Maximum bet: £5.00
Bets are selected by using the plus or minus buttons at the bottom of the screen. Once your preferred bet is set, press START to begin a round.
How Cluster Pays and Cascades Work
Gigantoonz rewards cluster wins, which occur when 6 or more matching symbols are adjacent, either vertically or horizontally, with no gaps in between. Winning clusters are removed from the grid, allowing new symbols to fall into place and potentially form additional clusters. Cascading continues as long as new winning combinations are formed.
All winning combinations in a single game round are added together, including winnings from any activated bonus features. At the end of a round, your total winnings are paid out. If free spin features are triggered, they are played using the same bet as the round that activated them. Bets cannot be changed during an ongoing round.
Mega Symbols and Wild Features
Mega symbols may land on any spin in sizes ranging from 2x2 up to 7x7. These special symbols have a randomised cluster value of up to 13, which determines their contribution towards wins. Mega symbols count as a single symbol in cluster calculations, but their payout is based on their assigned cluster value.
When a mega symbol is part of a win, it leaves a WILD symbol behind on the grid. If a mega symbol can't drop further, it turns into 1x1 symbols, each without a cluster value.
On non-winning rounds, between 5 and 10 QUANTUM WILDS can be randomly added to the grid. GARGANTOON WILDS may also appear via the QUANTUMETER feature. WILDS substitute for any other symbol to help create winning clusters.
The Quantumeter and Its Features
Each symbol involved in a win fills the QUANTUMETER by one charge, while mega symbols contribute their full cluster value. The QUANTUMETER can hold up to 100 charges and has four levels, each unlocking a special feature:
- 25 charges: DISINTEGRATION - Four randomly selected symbols are removed from the grid entirely.
- 50 charges: METAMORPHOSIS - All instances of one randomly chosen symbol are transformed into another symbol, including mega symbols.
- 75 charges: RADIATION - Between 0 and 4 mega symbols and 2 to 5 QUANTUM WILDS are added at random locations on the grid.
- 100 charges: GARGANTOONZ! - This bonus triggers in two parts after all wins are finished:
- All mega symbols transform into mega GARGANTOONZ, with at least 3 guaranteed to appear, plus 2 to 4 1x1 GARGANTOONZ. Mega GARGANTOONZ remain on the grid, even if part of a win.
- Once the first part concludes, mega GARGANTOONZ split into 1x1 GARGANTOONZ, which are removed as part of regular winning clusters.
The next available QUANTUMETER feature will trigger once no more cascades happen in a round. After all four features are played, the QUANTUMETER becomes inactive until it is recharged by new wins.
Playing and Winning
To play a round, select your desired bet using the buttons provided, then press START. Winning combinations can originate from any position on the grid, as long as symbols are connected either horizontally or vertically. Only the highest win per symbol combination pays, and all winnings are awarded at the end of the round, according to the paytable.
The paytable, which details symbol values and game rules, can be accessed at any time by selecting the paytable display. The RTP for this game is shown in-game.
Game Continuation and Malfunctions
If a game round is interrupted, all game data and any placed bets are saved until you reopen the game, allowing you to resume from the point where play stopped. Any unresolved bets in incomplete games will become void after 90 days. In the event of a malfunction, all pays and plays are voided.
