Managing Unfinished Game Rounds
If a game round is interrupted, all placed bets and relevant game details are saved until you resume play by reopening the game. You may continue your incomplete round from where you left off. Any unresolved bets that remain undecided in unfinished games will be voided after 90 days. In the event of a malfunction, all pays and plays will be voided.
Gameplay Overview
Gigantoonz is an 8-reel by 8-row cascading video slot from Play’n GO. The game uses a cluster mechanic, where winning combinations are formed by connecting 6 or more identical symbols horizontally or vertically with no gaps. Winning clusters are removed, causing new symbols to drop in and fill the grid, continuing cascades until no further wins can be formed.
Cluster Wins and Payouts
- Wins are achieved by forming clusters of adjacent matching symbols. A cluster consists of at least 6 symbols.
- All symbol clusters pay according to the paytable and game rules. Multiple cluster wins in a single round are added together for your total round win.
- Any wins from features or bonus rounds are added to your cluster win total at the end of the game round.
- Payouts are made only for combinations in which symbols are connected horizontally or vertically, with no gaps between them.
- Winning combinations can originate from any location on the grid.
- Only the highest win is paid for each winning combination of symbols.
Special Features and Symbols
- Mega Symbols: Mega symbols can appear in sizes ranging from 2×2 to 7×7. Each mega symbol holds a random cluster value up to 13, counting as a single symbol for wins, but its cluster value decides the payout. Every winning mega symbol leaves a WILD symbol in its place. If a mega symbol cannot drop further, it is replaced by smaller 1×1 versions without added cluster value.
- Quantum Wilds: On non-winning spins, between 5 and 10 Quantum Wilds may be randomly added to the reels. Gargantoon Wilds enter play via the Quantumeter. Wilds substitute for all other symbols.
The Quantumeter
- Each winning symbol adds 1 charge to the Quantumeter. Mega symbols contribute their cluster value as charges.
- The Quantumeter features 4 charge levels and can hold up to 100 charges:
- 25 charges: Disintegration
- 50 charges: Metamorphosis
- 75 charges: Radiation
- 100 charges: Gargantoonz!
- When there are no further cascades, the next charged feature activates. The Quantumeter becomes inactive after all features are played.
- Disintegration: Removes all instances of four randomly chosen symbols.
- Metamorphosis: Randomly transforms all instances of one symbol into another, including mega symbols.
- Radiation: Adds between zero and four mega symbols and two to five Quantum Wilds at random positions.
- Gargantoonz: Triggers in two stages after all wins finish. First, every mega symbol transforms into a mega Gargantoonz (at least three appear), along with two to four 1×1 Gargantoonz symbols. Mega Gargantoonz remain in place for wins. Next, each mega Gargantoonz breaks into 1×1 versions, which can be removed with ordinary wins.
