4 Fantastic Fish Gigablox Features

One thing that 4 Fantastic Fish fans love is the varied game board that brings a little bit of added excitement. The introduction of Gigablox makes this a potentially powerful base game that could bring some exceptional prizes. Speaking of which, winning symbols must land in a group of between two and six symbols, depending on the symbol. It all starts on the leftmost reel and a matching symbol must arrive on each subsequent reel. 

Royal symbols are the lowest payers while the Fisherman can get you up to 2.5x for a group of six. The payouts are fairly meagre and you will need to see the Gigablox providing some extra firepower here and there. These giant blocks represent a much larger number of winning symbols and you can see your payouts begin to grow quite nicely. 

The best wins will generally arrive thanks to the fish symbols which carry a value of up to 50x. If they form part of a regular win then you receive all of their face values. 

Over on the 6th reel, the Big Game Fish might appear and form the final piece of a large Fish symbol puzzle. If they complete a group of matching Fish symbols, the jackpot prize will be added. This ranges from 100x for the Big prize to a potential 10,000x for the Ultra prize.

Modifiers & Bonus Action

If you see the giant squid appear, then you can expect some crazy reel adjustments with four modifiers available. The seaweed symbols, which seemingly do nothing, might suddenly turn into winning symbols; Gigablocks can be called; symbols might be rearranged into a winning combination; or the squid could pick up the reels and move them around, which brings a winning result. It might not stop with just one either; various squid modifiers can appear together with potentially fantastic payouts on the horizon.

Scatter symbols unleash the Respin Bonus game with three lives presented. As long as you have three Scatter symbols, you’ll trigger the game and receive three open reels as a result. Other reels are locked until a Scatter symbol lands or a shark swims through. Fish symbols will replenish your respin lives and leave their values in place to add to your total. Incidentally, that shark doesn't only unlock the chained spaces but it'll also add a 2x multiplier to any prizes in its wake, and fresh multipliers are also released as the chained spaces become unlocked.

4 Fantastic Fish Gigablox - Giant Squid Bonus

Giant Squid Bonus

The squid returns to mess with the reels and brings a mountain of modifiers. Symbols can be converted into winning ones, Gigablox might be summoned to the reels, symbols suddenly swap places or the reels are shuffled. More than one might occur at the same time.

4 Fantastic Fish Gigablox - Fishing Respins Bonus

Fishing Respins Bonus

Three or more Scatter symbols trigger a 3-life respin game with various reels and rows now locked. Fish symbols refresh your lives and stay in place to add their value to the pot. Sharks are Collectors that bring the values together from an entire reel and add a multiplier. They also unchain any locked places and further multipliers are now released.

4 Fantastic Fish Gigablox Review

I’d argue that there’s more linking this game to the 2nd instalment, 4 Fantastic Fish in Egypt, than the first, despite the obvious design differences. But it does manage to keep in touch with both of its predecessors quite nicely and doesn't alter the thread too much. The addition of Gigablox is just enough to make this version feel like a decent revamp.


It's a cool Caribbean vibe that perks you up and keeps you fighting through this high-volatility shark pool. The skyline is perhaps a little basic and the same could be said for the overall presentation, but it somehow works and the cartoon feel provides a decent enough backdrop for all of these features. The game plays just as well on smaller mobile devices and you can't argue with that cheeky squid who pops up from time to time, bringing a little additional modifier to your gameplay.


Gigablox have the potential to blow up your balance when they arrive in the right places. However, if they don't, then you will be waiting for that elusive squid to mix up the reels a little or some Scatter symbols to take you away from the base game. It all depends on what mood the slot’s in as to how much excitement it will provide. It can be great fun when it's firing on all cylinders but the modifiers weren't frequent enough for me to make a mediocre run of spins feel entertaining.

Win Potential

I feel like 4 Fantastic Fish Gigablox would have benefited from much lower volatility given the setup. As it stands, the high volatility will bring the occasional big win but also some regular lulls in the action. 12,000x is the top possible payout and the RTP is 96%.

My Verdict

With a slot pool as crowded as the fishing niche, there’ll always be something to amuse each and every one of us. Regardless of the fact that it didn’t tick every one of my demanding boxes, 4 Fantastic Fish Gigablox could be the one for you. There’s real potential here for some incredible bites if you’ve got your hook in the water, so to speak.
