Hades Gigablox Slot Review

Released October 2020

The Hades Gigablox slot is produced by Yggdrasil Gaming. Yggdrasil Gaming take their name from Norse mythology where Yggdrasil is a magical tree where dragons lived and Odin sacrificed himself. Yggdrasil Gaming are one of the smaller slot development companies on the market at the moment – primarily focusing on lottery and scratch card game – and do not offer a full casino platform. They lease their games out to casinos using other platforms as a bolt on package. Yggdrasil Gaming publish the Return to Player/House Edge of their slots games within the game help file. The House Edge of Hades Gigablox is 4%.

Hades Gigablox is a 6 reel game, with space on each reel for 6 symbols. The slot uses traditional paylines, with 50 in total, playing from left to right. The Gigablox mechanic means that the size of the symbols landing can change, to the extent that it is possible to land a 6x6 symbol that fills the entire reel. This means that each spin can bring about wildly different possibilities.


This is a Greek themed slot. Just in time for Halloween we are plunged into the depths of the Underworld where Hades awaits. Expect plenty of fire and brimstone as you go head to head with the lord of the Underworld.

Special Symbols

Wild – Wild symbols will substitute for all regular symbols but are only available in the Hades Wild Hunt feature.

Scatter – You need to land 5 or more of the Scatter symbols to trigger the Free Spins feature.

Bonus Features

Hades Wild Hunt – This is a random feature, meaning it can trigger at point. If it does trigger there is a chance that the monster symbols on the reels will turn into Wilds. Hades will leap from the right side of the reels and enter the Monster symbols where he will battle with each one individually. If he wins (something that is determined at random) the monster symbol will turn Wild. He can win some fights and lose some fights in the same round. This is the only way that you can have Wilds on the reels.

Free Spins – You will be given at least 5 Free Spins, as you get one spin for each triggering Free Spin symbol. Additionally, every Free Spin symbol you land during the Spin will award an extra Free Spin. Every spin will come with a Hades Wild Hunt and every successful fight will add 1 to the Multiplier counter. 10, 15, 20 and 25 successful Hades Wild Hunt will increase the multiplier to 5, 10, 15 and 20x the bet, respectively.


Yggdrasil have created a slot that is as close to a piece of art as you are likely to in an online casino lobby. And it’s not all about the aesthetic with this one. You might only have 2 features but the Hades Wild Hunt feature is super engaging and the fact that it happens on every one of your Free Spins is a massive bonus. The Gigablox always feel like a poor man’s Megaways to me but they do improve the experience. The house could do with being a little more competitive.
