Discover the Gargantoonz Slot Experience

Gargantoonz is an online slot created by Play’n GO, offering a cascade-style 7×7 grid. The game is designed around cluster wins, providing engaging features and bonus mechanics for players.

How to Play

• The slot features a 7-reel format with symbols arranged in a 7×7 grid.
• Bets can be placed from a minimum of £0.10 to a maximum of £5 per spin.
• To adjust your bet, use the plus and minus buttons to move up or down in value. Once your bet is set, begin the round by pressing spin.

Winning combinations depend on clusters of matching symbols. Cluster wins are formed when five or more identical symbols connect horizontally or vertically, without gaps. These combinations may start in any area of the grid.

Understanding Cluster Wins and Payouts

• Winnings are paid when five or more symbols are clustered together horizontally or vertically.
• All cluster wins during a round are combined and awarded at the end of the round.
• Winning symbols are then removed from the grid, and new symbols cascade into place, possibly triggering further wins within a single game round.
• Only the highest win per winning symbol combination is paid out.
• Details on payouts for each symbol can be found in the in-game paytable.

Wild Symbols

Wilds have the ability to substitute for any other symbol, helping to create or extend winning clusters for more potential wins.

Fluctuating Symbols and Quantum Wilds

• On each round, a one-eyed symbol type is randomly selected as the fluctuating symbol.
• If a fluctuating symbol forms part of a win, between 1 and 2 Quantum Wilds may appear in place of removed symbols.
• If no win is achieved on a round, between 4 and 8 Quantum Wilds may randomly be added to the grid, enhancing chances for future wins.

The Experiment Charger System

The Experiment Charger is a key feature in Gargantoonz. When active, winning symbol clusters contribute toward charging the Experiment Charger.

• If no experiment is currently underway, 20 symbols are needed to fully charge.
• Once filled, one of three possible experiments is selected at random and triggered after all cascades have resolved.
• If an experiment completes successfully, another may begin until all three have occurred. If unsuccessful, the experiment phase ends.

At the onset of an experiment, unique Wilds are distributed across the grid, and all existing Wilds are transformed into the current experiment’s Wild type. When an experiment is active, only Wild symbols contribute to recharging the Experiment Charger, with a requirement of 40 symbols to recharge it fully and another 40 to achieve an overcharge, which increases the Gargantoonz multiplier by one.

Experiment Features

• Gamma Ray Burst: Between 7 and 9 Wilds are added to the grid. Winning Wilds tally the number of symbols in their clusters, then all those symbols are counted and removed. Each Wild’s effect is counted once, even if included in multiple winning clusters. When counting finishes, the Wilds leave the grid, charging the Experiment Charger prior to any further cascades.
• Black Hole: 4 to 6 Wilds are placed on the grid. Winning Wilds remain until there are wins, and then gather all adjacent symbols—horizontally, vertically, and diagonally—upon leaving, charging the Experiment Charger. If three or more Wilds group together, they immediately trigger, charge the loader, and exit the grid without remaining for subsequent wins.
• Supernova: 3 to 5 Wilds appear. These Wilds remain on the grid if they win, moving one diagonal step for each new cascade, provided they do not collide with each other. After cascades, each Wild moves up to eight steps, collecting symbols and charging the Experiment Charger upon departing. Like the other experiments, if three or more Wilds cluster together, they trigger and leave straight away.

The Gargantoon Charger and Multiplier

Each successful experiment advances the Gargantoon Charger, helping the Gargantoon evolve. The Gargantoon Charger begins with a x1 multiplier applicable to the Gargantoonz feature. Each time an experiment is overcharged, the multiplier increases by one—up to x4. If all three experiments are successfully completed, the Gargantoonz feature is activated.

Gargantoonz Feature

When this feature is triggered, it unfolds in three phases:

1. Eight 1×1 Gargantoon Wilds land on the grid, staying in place and merging even if they form part of a win.
2. The 1×1 Wilds then merge into two 2×2 Gargantoon Wilds, appearing after wins are awarded but before new symbols cascade, and remain to merge again.
3. The two 2×2 Gargantoon Wilds join into a single 3×3 Gargantoon Wild, also after wins and prior to a new cascade. This Wild is then removed when involved in a winning cluster.

Each Gargantoon Wild applies the appropriate multiplier, although if several Gargantoon Wilds are present in a cluster, only one multiplier will be used for the win.

Payouts and In-Game Help

At the end of each round, all winnings from clusters and features are combined and paid. Cluster wins from the bonus features are also included. Free Spin features, when awarded, will be played with the initiating bet. Bets cannot be changed during an active game round. For more details, consult the in-game paytable and rules.
