100 Spins Test

This 100 Spin will be updated by Steve Madgwick 

100 spins is not a Real Test

We give every slot a 100 spin test to see just what it can do, or not as the case can often be - 100 spins is no reflection of the likelihood of any other 100-spin session, as RTP's are set over many millions and probably billions of spins. So this 100 spin test is just for entertainment and insight purposes

Game Data

Collected by Andrej Trajkovski


An old Chinese proverb tells us, 'To give a man a fish, you feed him for a day. Teach a man to fish, and you feed him for a lifetime.' This proverb makes sense in all areas of life. Fishing is an ancient practice and is a popular pastime for many people. This is reflected in the number of fishing-themed slot games available. You'll find many options if you google 'fishing slot games'. So, don't go anywhere if you want to find out if this game stands out from others that are out there.

As well as the impressive Gigablox mechanic, look out for the Giant Squid, a key feature which was in in the previous two games. The Giant Squid offers 1 of 4 unique features on any spin: Squid Shuffle, Squid Swap, Squid Reveal, and Giga Summon.

During this in-depth 4 Fantastic Fish Gigablox slot review, you can read about all aspects of this new release, so let's get stuck in and cast the net wide.

Graphics, Music, and Sound Effects

People who are keen on fishing often cite relaxation and connection to nature as reasons that they enjoy their hobby. This game certainly includes plenty of blue hues and the imagery of the serene sea.

The music is laid back with a reggae influence, and the sound effects include bubbles and other ocean-related sounds.

Key Features

Written by Slots Content Manager Jenny Mason

Right, now that I've covered the summary, intro, graphics, music, and sound effects, up next are the key game features.

At OLBG we create slot game reviews that include current info about essential features such as the theme, paylines, reels, bet range, and bonuses. I’ll finish off the review by talking about my play experience, first impressions and expert verdict.

Theme – Fishing

As you'd expect from a fishing-themed game, you'll see plenty of shades of blue in the background image, complete with dazzling fish and swaying seaweed moving with the currents. The grid has the same azure hues, and looking at the character symbols by highest value. The first symbol is a man fishing, a seagull, a crab, a starfish, a fishing rod and a tackle box. The standard symbols of A, K, Q, J and 10 then follow this. The general vibe of the game is cheery and bright.


The 4 Fantastic Fish Gigablox game is made up of 6 reels and 6 rows to play with. 


There are 46,656 paylines where you can trigger winson the 4 Fantastic Fish Gigablox game.


Return to Player is most commonly referred to as RTP, which you've probably seen on slots sites. It's a way of forecasting theoretically what percentage of a player's stakes will be returned to them over the long run. The higher the number, the better, and ideally, the rate should be 96% or above. 4 Fantastic Fish Gigablox is about average at 96%.

This RTP figure is used as a default value by the studio 4ThePlayer, so if you shop around, you’ll discover several rates. To save you some time, we’ve uncovered a few at some of the top UK online casinos and added them to the table below.

It's worth mentioning that RTP is just one consideration when deciding which site to play at. Other factors include payment options, game library, customer support and welcome bonuses and deals. Our casino reviews look at this info and much, much more.

Stake Range

The 4 Fantastic Fish Gigablox  game has a bet range which starts at £0.10 and goes up to £80.

Max Win

The max win amount for the 4 Fantastic Fish Gigablox slot game is 10,000x your stake.

Wild Shape

The Wild symbol suibsititutes for all symbols apart from the Scatter symbol.

Free Spins

The Free Spins bonus round is called the Fishing Respins Bonus. If you land 3 or more Scatters you'll trigger the Respin Bonus. The reels will open by landing Scatters on them and then Fish symbols with cash prizes lock on to the open reels. Gigablox symbols can land in any position on the reels and they split and lock in any open-reel positions that they land on. The top and bottom rows are locked and contain cash multipliers. You can unlock them with the shark feature which will be explained below. Every unlocked Fish and Scatter resets to 2 respins and then all Fish symbol cash prizes are awarded at the end.

The Shark feature eats full reels of Fish symbols to combine the prizes and multiply them by 2x. It will then combine the prizes and multiply them by 2x. The shark unlocks the top and bottom positions on a reel. If you land new Fish symbols in the positions anycash prizes will be multiplied.

Play Experience & First Impressions

When launching the game, I didn't know what to expect as the graphics were not as high res as other games on the market. However, the features are where this game shines. There are numerous ones to enjoy, which I'll explain in this section. The Gigablox feature has been mentioned already, but here, massive symbols appear on enlarged reels. you'll discover symbols up to an impressive  5x5 on the grid. Another layer here is that Fish symbols can land as Gigablox and split into 1x1 symbols if the Gigablox forms part of a win. This mechanic looked fantastic on the reels - it was certainly a case of the bigger the better.

The Fish symbols are a core component, and with these, you can fish for cash prizes. Fish symbols can land on any reel and award cash prizes if they find a way to win. Cash prizes range between 0.1x and 50x of your bet. Watch out for the bigger fish with bigger cash prizes, which appear on the reels on the right of the grid. These are called Big game fish and they pay out on the fish symbol wins; here is a list of the payouts: 

  • 5x5 gigablox each 1x1 symbol wins £400. Win up to £10,000
  • 4x4 Gigablox  each 1x1 symbol wins £125. Win up to £2,000
  • 3x3 Gigablox  each 1x1 symbol wins £50. Win up to £450
  • 2x2 Gigablox  each 1x1 symbol wins £25. Win up to £100

The Giant Squid Bonus is another headline feature that can pop up randomly, this feature has four different elements that can trigger, and each one has a different role:

  1. Squid Reveal - is where seaweed reveals winning symbols.
  2. Giga Summon - this calls Gigablox to the reels, and the Gigablox can be up to 5x5.
  3. Squid Swap - here, symbols will be swapped to create wins.
  4. Squid Shuffle  - the reels are shuffled to create wins.

When testing 4 Fantastic Fish Gigablox, the Squid Swap feature triggered and visually, it looked fantastic and added to the entertainment factor and it can also mean some decent wins during gameplay.

Expert Verdict

4 Fantastic Fish Gigablox is the third title of this fishing-themed series.4 Fantasic Fish was released in June 2022, and 4 Fantasic Fish Egypt was released in May 2023. Both of the previous games had 4,096 pay lines with a 12,000x max win. So this latest game has a slightly reduced max win at 10,000, but the pay lines have increased massively up to 46,656 due to the Gigablox feature. The Gigablox feature is certainly a highlight of the game and should be something players enjoy. The graphics score at the lower end of the scale, although the features score high on the scale, so maybe this balances things out. The game is stuffed with features, but they are straightforward and entertaining, which is an excellent combo. Fishing-themed games seem to be popular amongst slots players, But this game does stand out to others on the market due to the superb features. It is fair to say that 4 Fantastic Fish Gigablox has reeled us in.
