The fan-favorite fishing slot series from 4ThePlayer takes a massive leap forward with 4 Fantastic Fish Gigablox. While earlier titles like 4 Fantastic Fish in Egypt and 4 Fantastic Lobsters added small variations to the original, this entry introduces something game-changing: the Gigablox mechanic.
With colossal fish symbols, creative modifiers, and a respin-based bonus round, this slot blends familiar fish-for-cash mechanics with explosive new gameplay. Whether you're here for the chill sea vibes or chasing those 10,000x wins, you're in for a wild day on the water.
4 Fantastic Fish Gigablox is played on a 6-reel layout and combines standard symbols with fish symbols that carry instant cash values. The base game also introduces Gigablox symbols, which appear as oversized blocks of up to 5x5 in size.
Wins are formed when fish or matching symbols align in winning combinations. Fish values are instantly awarded when they form part of a win, and the game leans heavily on bonus modifiers and features to keep things exciting from spin to spin.
With bright underwater visuals, detailed aquatic animations, and a light-hearted soundtrack, this slot captures the feel of an adventurous deep-sea fishing trip. The highlight, though, is the massive fish symbols that crash onto the reels as Gigablox blocks — visually impressive and rewarding.
There’s also plenty of character, with the sneaky Giant Squid making surprise appearances to shake up the reels and a hungry Shark lurking in the bonus game for some high-stakes action.
Fish for Cash
Fish symbols display instant cash values ranging from 0.1x to 50x your stake. These are awarded when fish form part of a winning combo. Bigger prizes come via the Big Game Fish symbols, which land as Gigablox blocks on the rightmost reels:
Big Fish (2x2) – Pays 25x per cell, up to 100x total
Super Fish (3x3) – Pays 50x per cell, up to 450x total
Mega Fish (4x4) – Pays 125x per cell, up to 2,000x total
Ultra Fish (5x5) – Pays 400x per cell, up to 10,000x total
Giant Squid Modifiers
At random, the Giant Squid can appear to activate one of four special modifiers:
Squid Shuffle – Rearranges reels to form a win
Squid Swap – Swaps individual symbols to create a payout
Squid Reveal – Turns seaweed symbols into matching symbols
Giga Summon – Spawns a large Gigablox (minimum size 4x4)
These random events can trigger anytime during the base game, keeping each spin unpredictable.
Fishing Respins Bonus
Land 3 or more Scatters to trigger the Fishing Respins Bonus, a streak-style feature with 3 respins to start. Only fish symbols and blanks appear here, and each time a fish lands, the respin counter resets to 3.
How it works:
Only reels with triggering Scatters are unlocked at the start; others are locked.
Land a Scatter on a locked reel to unlock it.
Fill all positions on an unlocked reel to activate the Shark Feature.
The Shark eats all fish on that reel, then leaves behind one symbol worth 2x their total value.
The first time this happens on a reel, it unlocks the top and bottom rows, each with random multipliers. If fish land there, the multipliers are applied.
Gigablox fish can appear in the bonus, and any fish landed on unlocked reels remain sticky. The feature ends when spins run out or the entire grid is filled.
If you’d rather skip straight to the action, 4 Fantastic Fish Gigablox offers two buy options:
Fishing Respins Bonus – Costs 80x your bet and starts the respin round immediately with at least 3 Scatter symbols.
Giga Summon Spin – Triggers a base game spin with a guaranteed 4x4 or 5x5 Gigablox, for 150x your bet.
Both options offer high-risk, high-reward gameplay depending on your style.
