Champion-of-the-Underworld

Apparently, Yggdrasil is starting an ‘of the Underworld’ slot series, and Champion of the Underworld seems to be the first installment. They have a few related releases from before though, but not with that exact wording in the title. In addition to Wild Fights at random times in the base game, you also get a dynamic grid experience via the Gigablox symbols.
They don’t really change the grid though, as they count as 1×1 sized symbols when part of anything. The 6×4 reels setup with 4,096 win ways is something this developer does well, and the cartoonish underworld visuals displays a massive arena where different ungodly creatures duke it out with Hades himself. The10,000x potentialis solid, and this is a game well worth checking out.
You getGigablox symbolsup to size 4×4 on each spin, and the Gigablox symbols are broken down to regular 1×1-sized symbols if part of a win. The 4 demon-like premium symbols pay between 1 and 2 x your stake for 6 of a kind wins, and theSkull Wildsteps in for pay symbols to help complete wins.

You get to see a few base game wins, before we purchase the top-tier bonus round at 0:50 into the 12-minute highlights video. As you probably understand, the feature went on for quite a while, and you can see for yourself how we fared by hitting the play button below.
We like the idea and concept this Yggdrasil release is built around, as it’s not too hard to imagine nasty creatures in the underworld duking it out tournament style for entertainment and hierarchy-climbing. The execution is pretty solid as well, and Champion of the Underworld comes with engaging visuals and scary looking multi-eyed monsters.
The soundtrack became a bit too repetitive after a while though, but Gigablox and random Wild Fights keeps the base game varied and interesting. The bonus round varies a lot as well, and starting with a larger number of spins is a huge advantage when it comes to climbing the multiplier ladder. The10,000x potentialis decent enough, and overall Champion of the Underworld is a decent installment in the Gigablox/Wild Fight range.
