4 Fantastic Fish Gigablox Slot Review
4 Fantastic Fish Gigablox is a striking collaboration between 4ThePlayer and Yggdrasil Gaming that brings the beloved Fantastic Fish series into the Gigablox era. Released in February 2024, this 6×6 video slot combines a fishing theme with Yggdrasil’s popular Gigablox mechanic, creating a compelling high-volatility experience. With a 96% RTP, 12,000x maximum win, and multiple bonus features, it’s a standout entry in the expanding Gigablox portfolio.

Base Game & Features
The game operates on a 6×6 grid with 46,656 ways to win, giving every spin multiple opportunities to land combinations. Gigablox symbols appear in sizes ranging from 2×2 to 5×5, and when they form part of a winning combination, they split into individual 1×1 symbols, often creating cascading wins. The multi-tiered Big Game Fish system forms the core of payouts: Big Fish (2×2) pays 25x-100x, Super Fish (3×3) pays 50x-450x, Mega Fish (4×4) pays 125x-2,000x, and the towering Ultra Fish (5×5) pays up to 10,000x per symbol position.
Beyond the main symbols, the Fish for Cash mechanic awards instant prizes ranging from 0.1x to 50x your bet, with larger fish on the rightmost reels carrying proportionally bigger payouts. The Giant Squid Bonus injects unpredictability into base play, triggering randomly to apply one of four modifiers: Squid Reveal (exposes winning symbols), Giga Summon (adds Gigablox up to 5×5), Squid Swap (rearranges symbols for winning combinations), or Squid Shuffle (randomises the reels). This keeps base game sessions varied and engaging without relying entirely on scatters.

Bonus Features & Free Spins
Landing 3 or more Scatter symbols triggers the Fishing Respins Bonus, the game’s marquee feature. You start with 3 respins, and each time a fish symbol lands, the counter resets back to 3, allowing the bonus to extend potentially indefinitely. All fish symbols lock in place throughout the bonus, building combinations across respins. During this phase, the Shark Feature can activate, combining all cash prizes into a single position and doubling them with a 2x multiplier. Special Cash Multiplier positions on the top and bottom rows can be unlocked through the Shark Feature, substantially increasing winning potential.
For impatient players, Feature Buy options provide direct access: purchase the Fishing Respins Bonus for 80x your stake or trigger a Giga Summon Spin for 150x your stake. These costs are competitively priced within industry norms and offer genuine value given the payout potential. Feature Buy availability is subject to regional restrictions.

Our Honest Verdict
4 Fantastic Fish Gigablox deserves a 4.5 out of 5 rating. This game achieves something rare: it successfully merges two established concepts—the Fantastic Fish heritage and Yggdrasil’s Gigablox mechanic—into a cohesive, engaging whole. The multi-tiered Big Game Fish payouts create genuine excitement, the Fishing Respins Bonus with infinite extension potential sustains engagement, and the Giant Squid Bonus keeps base play dynamic without feeling random or cheap. Visually, the game is polished with crisp aquatic graphics and an immersive reggae soundtrack that creates an enjoyable Caribbean atmosphere.
The 12,000x maximum win is solid but falls short against competing Gigablox titles like 90K Yeti (90,000x), which may disappoint pure max-win hunters. The high volatility demands patience and a robust bankroll—this isn’t a game for rapid-fire small wins. Audio can become repetitive during extended sessions. However, for Gigablox enthusiasts, high volatility seekers, and players who thrive on feature engagement, 4 Fantastic Fish Gigablox is absolutely worth exploring. The game stands out in the fishing slot genre precisely because it doesn’t rely on theme alone; the mechanics deliver genuine depth and the bonus structure sustains lengthy play sessions.
