About Gargantoonz

Gargantoonz is an online slot game developed by Play’n GO. The game features a 7-reel, 7-row grid, with wins awarded for forming clusters of 5 or more matching symbols positioned adjacently, either horizontally or vertically, with no gaps. The outcomes for each round are determined by the symbols displayed, and any wins are shown according to the paytable.

Betting Information

• Minimum bet: £0.10
• Maximum bet: £5

Bets can be adjusted using the plus and minus buttons before starting a round. During a round or any triggered features, the bet level remains locked until the round is finished.

How to Play Gargantoonz

1. Select your preferred bet size using the plus and minus bet buttons.
2. Start the round by clicking the spin button.
3. Symbols will fall into place on the 7×7 grid.
4. Form clusters by landing 5 or more matching symbols connected horizontally or vertically.
5. Winning clusters are removed, triggering new symbols to drop into the grid. Cascades continue until no further wins are possible.
6. All wins are paid out at the end of the round, with all features and bonus wins added together.

Features and Game Mechanics

• Wilds: Wild symbols substitute for all other symbols. On any non-winning round, between 4 and 8 Quantum Wilds may randomly appear on the grid.
• Fluctuating Symbol: At the start of each round, a one-eyed symbol type is randomly chosen as the fluctuating symbol. If fluctuating symbols form a win, 1 to 2 Quantum Wilds are placed where removed symbols were.
• Cascading Wins: Each time a cluster win is achieved, the symbols involved are removed, and new symbols drop into the empty spaces. Cascades continue until no new cluster wins can be formed.

Experiment Charger

The Experiment Charger fills when cluster wins occur and no experiment is ongoing. 20 symbols are needed to fully charge the charger at this stage. Once full, an experiment is selected randomly and begins when all cascades from the triggering win are complete. If an experiment succeeds, a new one is triggered, continuing until all three distinct experiments have been played or an experiment cycle concludes. When an experiment is active, only Wilds contribute towards charging, requiring 40 symbols to charge the experiment. An overcharge of a further 40 symbols increases the Gargantoonz multiplier by 1.

Experiment Features

• Gamma Ray Burst: Between 7 and 9 Wilds are added to the grid. Wilds in winning clusters count the number of matched symbols before removing all instances of those symbols, then exit the grid after charging the experiment.
• Black Hole: Between 4 and 6 Wilds are placed. Winning Wilds remain on the grid if wins continue, and after cascades finish, they collect all directly connected symbols before departing to charge the experiment. If 3 or more Wilds cluster together, their effect is triggered immediately.
• Supernova: Between 3 and 5 Wilds appear. Winning Wilds remain if they help form wins and can shift diagonally one step per cascade without crossing. After all cascades, Wilds move up to 8 steps, collecting symbols in their path. If 3 or more Wilds gather in a cluster, they trigger instantly.

Gargantoon Charger and Feature

Each completed experiment charges the Gargantoon feature, causing Gargantoon to evolve. The Gargantoon charger starts with a base multiplier of x1, increasing by 1 for each experiment overcharge, up to multipliers of x1, x2, x3, or x4. If all three experiments are completed successfully, the Gargantoonz feature is triggered.

The Gargantoonz feature unfolds in three steps:

• First, eight 1×1 Gargantoon Wilds appear and can merge even if they are involved in wins.
• After wins are tallied, these 1×1 Wilds merge into two 2×2 Gargantoon Wilds, which remain on the grid.
• Subsequently, the two 2×2 Wilds merge into a single 3×3 Gargantoon Wild. This large Wild is removed when wins involve it.

Each Gargantoon Wild displays the current multiplier, but if multiple Gargantoon Wilds are in the same cluster, only one multiplier is applied to the cluster win.

Additional Details

• Winning combinations may start from any position on the grid.
• Only the highest win per symbol combination is paid.
• The value related to returns is shown within the game.
• All winnings from features or bonuses are combined with cluster wins and paid at the end of the round.
• If Free Spins are triggered as a feature (where applicable), they are played using the same stake that initiated them.

Please consult the in-game rules for more details on winning combinations, features, and gameplay mechanics.
