Ever wondered what kind of creatures might dwell in the Underworld, the mythical land of the death god Hades? Or what it would be like to pit them against each other in gladiatorial combat? No? Well now’s your chance to try anyway!

If there’s one thing Yggdrasil do well, it’s bringing their games’ fantasy worlds to life. To no one’s surprise, Yggdrasil Champion of the Underworld is one of the best-looking games to be released in 2022. It’s now just the beautiful hand-drawn art or the attention to detail. Everything about this game is oozing with atmosphere, right down to the catchy soundtrack.

So we know Yggdrasil games look great, and we sure as hell (pun intended) know this new release looks great. But how does the game actually play, and is it worth your time? That’s what our Champion of the Underworld review is here to find out!

Once the game grips you with its eerie atmosphere, you’ll find yourself in the depths of Hades. It’s teeming with the sort of creature you’d expect to find in the Underworld – demons, gorgons, minotaurs, and the like. They live at Hade’s command – which appears to be too fickle to grasp for us mortals.

Let’s not get ahead of ourselves, though. Mechanically, Champion of the Underworld is a 5×3 slot with no pre-set paylines. What this means is that you simply need to arrange 3 or more matching symbols on connected reels, going from left to right. As a result, there are over 4,000 ways to win. This makes it deliciously volatile, of course.

The defining features of Champion of the Underworld are the monsters themselves and the battles between them called the Wild Fight. In terms of gameplay, some of the high-paying monster symbols will occasionally duel each other. Basically, all of the symbols of a certain type of monster will square off against all of the symbols of a different kind currently present on the table.

One of these types of monsters potentially wins, and the side that lost are all turned into Wilds.

We can’t really notice a pattern in which side wins and why. However, you need at least two types of monsters on the table for the fight to happen. Still, it adds a nice bit of flavour to the experience, even if it’s completely out of the player’s hands.

Casino Bloke Best tips for Champion of the Underworld Slot

  • 1You can Buy Features to trigger 5 or 20 free spins for 90x and 1,000x your stake.
  • 2Bear in mind that every Free Spins symbol that appears during Free Spins awards an additional spin. This happens fairly often, so most free spin rounds in Champion of the Underworld last a lot longer than their initial bonus.
  • 3Every time you trigger Free Spins, you can choose to Gamble for more. This opens a minigame in which you have to pick a golden sword from a stack of hidden blades. The fewer golden swords in the pile, the more free spins you stand to win.
  • 4However, picking a broken sword will forfeit all of your free spins. You can do this up to a maximum of 20 free spins.


We already described the Wild Fight. Of course, this means that the game comes equipped with Wild symbols. Most fans of online slots should be familiar with those. They replace any other symbol, but cannot appear on reel 1.

Additionally, the game uses a trademarked Yggdrasil mechanic called Gigablox. Essentially, some symbols may appear as large 2×2 versions of themselves. They don’t do anything special – just imagine the Gigablock was simply a collection of 4 symbols. However, they do make it slightly easier to form winning lines. One Gigablox tile is guaranteed on every spin in this game.

You will need at least 5 free spins to land anywhere on the table to trigger the free spins round.

Free Spins in Champion of the Underworld trigger if you land 5 or more free spins, and the corresponding number of spins is awarded. Additionally, any Free Spins symbols appearing during the bonus round itself grant an additional spin.

Wild Fights can also trigger during free spins. If they’re successful (if one of the monster symbols is turned into Wilds), you get a +1 on the multiplier counter on your left for each created Wild. Getting enough of these will multiply all the winnings in the Free Spins round. Here’s how many you’ll need:

Every time you reach another multiplier level, the counter resets back to 0. However, you get +2 free spins.


Champion of the Underworld boasts 4 high-paying symbols and 4 low-paying ones. Combined with the fact Wilds are found on almost every spin, the hit rate is remarkably high.

That said, don’t expect to win too much on every spin. Even “high-paying” monster symbols cover a fraction of the stake used for one spin. This implies more than one winning match is required to make a spin worthwhile. That’s not too hard to do, though, considering how Champion of the Underworld works in terms of its 4,096 ways to win.

However, the game rewards stringing together multiple wins. The best way to make large profits is through the Free Spins round. Specifically, you want to make long-lasting free spins rounds that activate multipliers. Because of the multipliers, the value of free spins increases exponentially the more you have of them.

what we like

  • Incredible visuals
  • Immersive atmosphere with a great soundtrack
  • Powerful, purchasable free spins round
  • Plenty of Wilds that pay well and appear often

what we don’t like

  • Very low base payouts
  • No Free Spin counter during the Free Spin round


There’s a lot more to Champion of the Underworld by Yggdrasil than first meets the eye. The Dilf Fight mechanic seemed like a simple matter of randomness at the beginning. However, the way these turn out can have an enormous impact on some parts of the game. For instance, a small Free Spins round can be turned into a massive payout you’re not likely to forget soon.

The fun interactions the symbols have between themselves make for an interesting, replayable game. Every new session feels like a new adventure – we played over and over again, and things never seemed to get stale.

If you like long-lasting, high-paying streaks of Free Spins, definitely check out Champion of the Underworld.
