Theme – a colourful underworld battle
Theme: Fantasy
High Value Symbol: Red Bull
Compatibility: Mobile, Tablet, Desktop
The theme in the Champion of the Underworld slot is all about the underworld and the fantasy creatures fighting in the supernatural world of the dead. The game follows on from Hades: Gigablox, but the overall theme here is not as menacing in comparison.
The reels are set in an underworld arena, which looks rather gladiatorial. This accompanies a tense and suspenseful soundtrack, which gives it an eerie feel. Dark rock music then comes into play as you spin the reels to add to the intensity. It all works very well together.
On the reels, the card suits of clubs, diamonds, spades and hearts make up the lower-paying symbols. The higher-paying ones consist of a horse, a four-eyed lady, a medusa-like character and a bull. The red bull is the most rewarding symbol, paying 0.25, 0.5, 1 or 2 x your stake for 3, 4, 5 or 6 in combination.
The game’s Wild is a golden skull, which substitutes for all regular symbols. Here’s a helpful table listing the symbols you’ll come across in the game:

3, 4, 5 or 6 = 0.1, 0.15, 0.25 or 0.5 x stake |

Champion of the Underworld Mobile
The Champion of the Underworld mobile slot game has been produced using the latest HTML5 technology. It’s compatible with landscape and portrait on all smartphone devices. The 6×4 setup plays very well on smaller screens.
Champion of the Underworld Bonus Features
There are 5 bonus features here, but just 1 main one is at the forefront of the action. That is the Free Spins feature, which comes with Multipliers and the chance to gamble for even more free spins in some territories. Let’s run you through everything about it.
Gigablox feature
This feature involves oversized symbols on the reels that act like normal symbols but in a 2×2 to 4×4 formation. Free Spins Scatters can also land as Gigablox in this game.
Wild Fight feature
On any spin in the base game, Hades can fight all high symbols to convert them into Wilds if he wins. There is also the chance to convert Gigablozx symbols into Wilds.
During the Free Spins feature, Hades fights on every spin, and each symbol that turns Wild will increase the Multiplier counter.
Free Spins feature
Land 5 or more Scatters in the base game to trigger the Free Spins feature with at least 5 spins. Each Free Spin Scatter that lands during the bonus round will give you 1 extra free spin.
As mentioned above, this bonus round comes with a multiplier counter, which is increased by 1 every time Hades wins a fight. The more you turn into Wilds, the bigger the multiplier, as shown in this table:
Total Symbols Turned Wild | Award |
First 9 | 2x multiplier plus 2 extra free spins |
Next 11 | 3x multiplier plus 2 extra free spins |
Next 13 | 5x multiplier plus 2 extra free spins |
Next 15 | 10x multiplier plus 2 extra free spins |
Next 17 | 25x multiplier plus 2 extra free spins |
25x is the maximum multiplier possible
Any Gigablox that is converted into Wilds is counted by their size. So for example, a 2×2 Gigablox Wild will count as 4 Wilds towards the overall counter.
Gamble & Buy Bonus feature
When triggering the Free Spins feature, you can gamble for more free spins unless you’ve already got a maximum of 20 initially. Simply choose a sword and you will win if it’s got a golden tip.
Players in most territories outside the UK can also buy the Free Spins feature. 90x your stake will get you 5 free spins, whereas 1,000x your stake will get you 20 free spins.
Champion of the Underworld Review Summary – unleash the power of Gigablox and Wild Fight
Champion of the Underworld combines the powers of Gigablox and Wild Fight for a fantastic experience. It’s all about transforming those symbols into Wilds for bigger wins, and it happens pretty frequently which is great to see. During testing, although super high in volatility, I landed some nice wins.
If you’re in the UK, you won’t have the option to gamble or buy any features, but that’s ok as the gameplay is enjoyable as you spin away hoping to land the Free Spins feature. The visuals are solid and the soundtrack works really well, which is not something you can say about every slot on the market today.
Overall, it’s a great release from Yggdrasil and it will suit players who enjoy the Gigablox mechanic. Let’s not forget that it has 25x multipliers in the Free Spins feature too for potentially even bigger wins up to 10,000 x your stake.
Perhaps the best Gigablox game of them all that you must try is 90K Yeti Gigablox from 4ThePlayer. There are plenty of bonus features here, 46,656 ways to win and 90,000 x max wins up for grabs.
- 10,000 x bet max wins
- Exciting Wild Fight feature
- 4,096 paylines
- Super high volatility
