How to Get Started with Gigantoonz
Gigantoonz is an 8x8 cascading video slot from Play'n GO. To begin, select your desired bet using the bet buttons located at the bottom of the game. Bets can be adjusted from a minimum of £0.20 up to a maximum of £5.00 by clicking the plus or minus buttons. Once your bet is set, pressing START or the spacebar will initiate the game round. The outcome of each round is determined by the combination of symbols displayed according to the paytable.
The Return to Player (RTP) value is displayed within the game itself.
Understanding Cluster Wins
Gigantoonz employs a cluster pay system, where wins are achieved by connecting groups of six or more matching symbols. These symbols must be adjacent to each other, either horizontally or vertically, with no gaps separating them. Clusters can begin at any point on the grid. When multiple clusters result in wins during a single round, all associated winnings are totaled. Only the highest win is paid per winning symbol combination, and all winnings—including those from features or bonus games—are paid out once the round concludes.
After a winning cluster is formed, those symbols are removed and replaced by new ones cascading down, providing additional chances to win within the same game round. Cascades will continue until no further winning clusters are formed.
Mega Symbols and Wilds
- Mega Symbols: These may appear in various sizes, including 2x2, 3x3, 4x4, 5x5, 6x6, or 7x7. Each mega symbol is counted as a single unit for win purposes but possesses a random cluster value of up to 13, which is used to determine payouts. If a mega symbol forms part of a winning cluster, it leaves behind a WILD symbol in its place. In situations where a mega symbol cannot drop further, the space it leaves will be filled with 1x1 symbols without cluster values.
- Quantum Wilds: On rounds that do not result in a win, between five and ten Quantum Wilds may appear at random. Gargantoon Wilds are introduced through the Quantumeter feature. All Wild symbols are substitutes and can replace any symbol to help complete winning clusters.
The Quantumeter and Its Features
Each winning symbol contributes one charge to the Quantumeter, while mega symbols contribute charges equal to their cluster value. The Quantumeter tracks up to four charge levels, holding a maximum of 100 charges. The levels and their corresponding features are as follows:
- 25 charges – Disintegration: Removes all occurrences of four randomly chosen symbols from the grid.
- 50 charges – Metamorphosis: Changes every instance of a randomly selected symbol into another symbol, including mega symbols.
- 75 charges – Radiation: Randomly adds between zero and four mega symbols and two to five Quantum Wilds to the grid.
- 100 charges – Gargantoonz: This feature activates in two steps after all winning cascades are completed. First, all mega symbols are changed into mega Gargantoonz (a minimum of three appear), along with two to four 1x1 Gargantoonz added to the grid. Mega Gargantoonz remain on the grid during wins and are not removed. In the second step, each mega Gargantoonz is broken down into 1x1 Gargantoonz, which are then removed in the standard way when they form winning clusters.
Quantumeter features are triggered once cascades come to an end in the current round. If all features have been activated, the Quantumeter becomes inactive until the next round.
