4 Fantastic Fish Gigablox: Slot Overview

Casino game maker 4ThePlayer’s ‘4 Fantastic’ series has now truly become a four-pack with the arrival of 4 Fantastic Fish Gigablox. This release blends the original 4 Fantastic Fish slot with the well-known Gigablox mechanic created by partner Yggdrasil Gaming. It’s a crossover that echoes what the studio achieved in 90K Yeti Gigablox, and in this case, 4 Fantastic Fish Gigablox keeps most of the first game’s core elements while adding the extra layer of chaos and scale that Gigablox delivers.

When it comes to colourful, relentlessly cheerful fish-themed slots, 4 Fantastic Fish Gigablox sits among the most vibrant. A stylised sun throws heavy yellow rays across the sky over rough seas as fish glide by, while upbeat reggae sets the tone for the fishing fun in a world where almost everything looks like it’s grinning—fish included. The key change is that the game grid has been reshaped into a 6×6 layout, allowing Gigablox symbols to appear, and the win potential has widened to up to 46,656 ways.

Using the plus and minus controls beside the oversized spin button, you can set your wager anywhere from 10 c to $/€80 per spin, with a default RTP of 96%. Once the reels get moving, two things stand out quickly. First, seaweed symbols are now scattered around the grid and, much like the ice blocks in 90K Yeti Gigablox, they carry no value and can’t contribute to wins. Second, Gigablox symbols appear when reels combine to create symbols of 2×2, 3×3, 4×4, or 5×5 in size. Fish symbols can also land as Gigablox, but they break down into individual 1×1 symbols when it’s time to calculate wins.

Hooked card royals 10-A act as the low-paying symbols in 4 Fantastic Fish Gigablox, returning 0.4 to 0.8 times the bet for a 6 symbol win. Higher-paying icons include a tackle box, reel, starfish, crab, seagull, and fisherman, each paying 1 to 2.5 times the bet for a 6 OAK win. The boat symbol serves as the wild, replacing any symbol other than scatters.

4 Fantastic Fish Gigablox: Slot Features

Fantastic Fish games are known for packing in plenty of extras, and 4 Fantastic Fish Gigablox follows suit. Here you’ll find fish for cash prizes, big game fish, the Giant Squid bonus, a fishing respins bonus, plus two feature buy options.

Fish For Cash Prizes

Fish symbols may land on any reel and show cash values ranging from 0.1 to 50 times the bet. When fish symbols land and create a winning way, they award the prizes they display. Keep an eye out for big game fish too, as these also pay as part of fish symbol wins:

• Big – 2×2 Gigablox where each 1×1 symbol pays 25x the bet up to 100x total.
• Super – 3×3 Gigablox where each 1×1 symbol pays 50x the bet up to 450x total.
• Mega – 4×4 Gigablox where each 1×1 symbol pays 125x the bet up to 2,000x total.
• Big – 5×5 Gigablox where each 1×1 symbol pays 400x the bet up to 10,000x total.

Giant Squid Bonus

The Giant Squid can show up on any spin and apply one of the following modifiers:

• Squid Reveal – seaweed symbols reveal symbols guaranteeing a win.
• Giga Summon – calls Gigablox to the reels up to 5×5 in size.
• Squid Swap – swaps symbols to create wins.
• Squid Shuffle – shuffles the reels to create wins.

Fishing Respins Bonus

Hitting at least 3 respin scatters activates the respin bonus. When the feature starts, each reel that shows a scatter is unlocked, while all other reels begin the round locked. Those locked reels can be unlocked, however, by landing a scatter on them during the respins. When fish symbols land, they lock in place on open reels until the feature ends. Gigablox symbols can also appear anywhere, splitting into positions and locking on any open reels where they land. The top and bottom rows start locked too, and are unlocked by the shark feature.

You begin with 3 respins, and the counter resets back to 3 whenever a new fish locks in or a scatter lands. Once the round finishes, all fish symbol cash values are awarded. Finally, when the shark turns up, it eats full reels of fish symbols, merging their values into a single spot and multiplying the total by x2. The shark also unlocks the top and bottom positions on a reel. If fish land in these unlocked positions, their cash prize is multiplied.

Buy Feature

The buy feature lets players purchase scatters to start the respin bonus for 80x the bet, or buy the Giga Summon, which is a one-off spin featuring a Gigablox reel up to 5×5 for 150x the bet.

4 Fantastic Fish Gigablox: Slot Verdict

Overall, the combination of 4 Fantastic Fish and Gigablox comes together smoothly. The main potential drawback is the seaweed symbols which, like the icy blockers in 90K Yeti Gigablox, take up space while offering no direct value—though the Giant Squid bonus can bring them to life. Beyond that, the new elements are largely welcome, including the greatly increased number of win ways and the bigger, more dramatic outcomes that oversized Gigablox symbols can help produce.

It’s also useful that fish money symbols can appear in larger forms, both in the base game and during respins. The trade-off is that when big game fish land, you’ll need the full symbol to be visible to collect the entire prize amount, unlike 4 Fantastic Fish where a single 1×1 big game fish symbol was enough to trigger the win. Still, it adds to the game’s swingy feel. As with the Yeti title, the Giga Summon bonus buy can be extremely volatile too—great fun in demo mode, but potentially harsh with real stakes. Or it could pay off, since a huge Gigablox symbol has plenty of ways to connect. The respins feature is broadly familiar this time around, aside from the presence of giga-sized fish drifting into view. One point that could make players hesitate is the 10,000x the bet max win, which looks far less eye-catching next to the 90,000x available in 90K Yeti Gigablox, reducing the appeal of the Giga Summon feature and buy. Anyone who’s seen the wild $75,000 hit in the Yeti game will understand why.

Taking everything into account, 4 Fantastic Fish Gigablox is a strong addition to the Gigablox lineup. If the lower maximum win doesn’t bother you, most adjustments here feel like upgrades, and much of what made 4 Fantastic Fish entertaining is amplified by the inclusion of Yggdrasil Gaming’s popular mechanic that reshapes reels and inflates symbols.
