Champion of the Underworld

Champion of the Underworld is the next installment in Yggdrasil’s “of the Underworld” series, a slot where you face four new monsters in Hades’ arena. It was released on October 6, 2022, and you can play it in the free demo with no sign-up.

What series is this game part of?

It’s the sequel in Yggdrasil’s “of the Underworld” series. Hades waits in the underground arena, and four completely new monsters appear. If you’ve been following the series, it’s a must-see among Yggdrasil slots.

How are GigaBlox and Wild Fight used together?

This game combines Yggdrasil’s signature mechanics, GigaBlox and Wild Fight. Some high-paying symbols turn into wilds to increase your wins, while GigaBlox makes the payouts more spectacular. Having both mechanics running on the same screen is what sets this game apart. The biggest moments come when a giant block symbol overlaps with wilds.

What gets boosted in the free spins?

The free spins mode gets stronger with each wild symbol. Wilds created by Wild Fight count too, so the more wilds appear, the hotter the free spins get. Base wilds plus the wilds from Wild Fight add up, so the more wilds on screen, the more powerful the free spins become. When they overlap with GigaBlox, the results are even more dramatic.

How does the free spins gamble work?

You can gamble the free spins at one of two volatility levels. You can also jump straight into the free spins with bonus buy, and wins come from 4,096 lines. Being able to choose the gamble level is unique to this game, so I recommend feeling the difference between each level in the demo yourself.

What should I check first in the demo?

RTP is 96%, volatility is very high, max win is 10,000x, and hit frequency is 25.76%. The bet range is €0.2 to €100. In the demo, pick each of the gamble’s two volatility levels and compare the free spins results. You can also use bonus buy to open the free spins right away and watch the wilds pile up.
