Reels/Paylines: 6 reels + 25 to 40 paylines

Stakes Range: 20p to £50 per spin

RTP: 96%

Max Win: 10,000 x stake per spin

The Golden Fish Tank 2 Gigablox slot follows on from Yggdrasil Gaming’s popular Golden Fish Tank and uses the Gigablox mechanic. With 6 reels, 4 rows and 25 fixed paylines, wins are created by landing 3 or more matching symbols from left to right on adjacent reels.

Playable from 25p to £100 a spin, there’s a Coin Value section below the reels where you click on the arrows to adjust the bet level accordingly. If you head to the Settings icon, you can change the spin speed, sounds, volume and adjust the Autoplay function. Some of these extras will not be available in the UK from November 1st, 2021.

The Golden Fish Tank 2 Gigablox RTP is 96% which is average but lower than the 96.4% offering in the original game. Expect a winning outcome every 4 spins or so as the hit frequency rate is 26%.

The variance is in the medium to high bracket whereas it was low in the original. The RTP may be lower in this sequel but the win potential is substantially higher. You can win up to 10,000 x your total stake per spin in Golden Fish Tank 2 Gigablox. In the first game, it’s only 400 x stake per spin.

Theme – Audio & Design Features – head to an aquarium

Theme: Fish

High Value Symbol: Green & Yellow Fish

Compatibility: Mobile, Tablet, Desktop


The Golden Fish Tank 2 Gigablox slot has a fish theme and is set inside an aquarium. Colourful and bright, it has a cartoon feel with the symbols floating on the screen. It looks a little like the Finding Nemo film graphically. The soundtrack is calming and tranquil.

On the reels you will see diamonds, clubs, hearts and spades (low value symbols). Then you have 4 different coloured fish. The green and yellow fish is the highest paying symbol giving you 1, 2.4, 6 or 12 x stake for 3, 4, 5 or 6 in combination.

Then you have a wild symbol which substitutes for all symbols bar the free spins scatter. It pays 1.6, 4, 8 or 20 x stake. Below is a table highlighting all payouts per symbol:

Golden Fish Tank 2 Gigablox Bonus Features

With a total of 6 bonus features, Golden Fish Tank 2 Gigablox focuses on treasure chests and free spins. The former can deliver cash prizes up to 500 x stake whilst the free spins sees you make picks to bring various modifiers into play.

Gigablox feature

As the Golden Fish Tank 2 Gigablox title suggests, it uses Yggdrasil Gaming’s Gigablox feature. On every spin, at least 2 adjacent reels will connect to form a colossal symbol, known as a Gigablox. The Gigablox symbols can appear 2×2, 3×3 or 4×4 in size. Gigablox symbols split in 1×1 symbols to calculate wins. During the free spins, the Gigablox can reach 6×6 in size (more details below).

Golden Bet feature

As with other Yggdrasil Gaming slot games, there’s a Golden Bet feature. Costing you an extra 20% per spin, your stake would rise to £1.20 per spin if playing at £1 a spin. In return for this extra investment, you get 1 extra feature when you play the free spins.

Treasure Chest feature


There’s a Treasure Chest feature here. Look out for the treasure chest symbol landing on reel 5 in the base game. When it appears, the treasure chest will reveal:

Cash Prize Between 2 and 500 x total stake
Free Spins 5, 9 or 16 Free Spins

Treasure chests also appear during the free spins and can award multiplier prizes and additional free spins. Finally, it can land as a Gigablox symbol but will only count as 1 symbol.

Free Spins feature


To trigger the all-important Free Spins feature, you need to land 5 or more Free Spins symbols anywhere on the reels. The number of free spins you’ll play is equal to the amount of Free Spins symbols appearing on the triggering spin.

Once in, you will be awarded between 3 and 7 picks of modifiers which are active during the free spins. This is what the modifiers give you:

Wild Fish 1 fish symbol is replaced with wilds
2x Multiplier 2x multiplier applied to all wins
Expanded Reels Play on a 6×6 reel set with 40 paylines. 6×6 Gigablox are possible
Extra Wild 1-2 wilds are added randomly on each free spin
Fish Stacks 1 fish symbol becomes super stacked on the reels
Extra Free Spins 1-5 extra free spins are added to your tally

Once you start playing, remember that Treasure Chests can land on reel 5. They can award cash prizes up to 500 x stake as well as give you more free spins.

When you trigger the Free Spins feature, you can use the Gamble feature. This gives you the opportunity to gamble for more picks, up to 8. Using this extra gives you a 2 in 3 chance of winning.

Finally, there’s a Buy Bonus feature. You can buy your way into the free spins by paying 60 x your total stake. If you have the Golden Bet feature active, it will cost 83.3 x your total stake. Either way, you will get between 5 and 16 free spins with 3-5 feature picks (or 4-6 feature picks for Golden Bet). This feature isn’t available to UK players though.

Golden Fish Tank 2 Gigablox Review Summary – more variety + much bigger win potential

Theme & Symbols

Sounds & Music

Bonus Features

RTP (96%)

Max Win (10,000 x)


Graphically, the Golden Fish Tank 2 Gigablox slot is very similar to the original game. The feature picks element in the free spins is also similar.

With the Gigablox mechanic incorporated, Yggdrasil Gaming has ramped things up in terms of volatility and win potential. Whilst the RTP is slightly lower (96.4% vs 96%), the variance is a lot higher and the max win is 10,000 x stake per spin as opposed to 400 x stake in the original.

The key to winning big is to get a good selection of modifiers in the free spins. The 2x multiplier extra is needed but more important are the Expanded Reels. This gives you more paylines (40) with 6×6 Gigablox possible.

If you like the Gigablox mechanic, 4ThePlayer has used it to devastating effect in 90k Yeti Gigablox. With 6×6 Gigablox symbols also possible, it comes with 90,000 x stake max wins.

  • 10,000 x stake max wins
  • Plenty of modifiers in free spins
  • Much better than original slot
  • Hard to get right modifiers in free spins
