Champion of the Underworld Review

Champion of the Underworld – how awe-inspiring and dangerous that sounds. Luckily, it’s not a trophy any (at least any human) can win in real life. Virtually, though, you can do it if you manage to defeat the other combatants in Yggdrasil’s Champion of the Underworld online slot.

As expected, out of Yggdrasil, this is one of those modern slots with thousands of ways to win and fantastic special features. You can win in 4,096 ways and beat your opponents to claim the prestigious title. By prestigious title, we mean wins up to 10,000x the bet, fitting for a highly volatile slot with an RTP of 96%.

You’ll see all kinds of mythical and fantasy creatures on the reels, all vying for the throne. The slot uses the Gigablox mechanic in addition to a new feature known as WildFight which can make things pretty exciting from the get-go.

Try the Champion of the Underworld for free or play the slot for real money in any Yggdrasil slot site.

Champion of the Underworld Slot Layout and Controls

The Champion of the Underworld slot has a 5x4 reel set, but the symbols include Gigablox, so it might be a bit confusing to ‘read’. But it shouldn’t be a big concern of yours, and there’s a guide that can explain things in detail.

Let’s focus on the symbols. That Minotaur-looking creature pays the most – a mere 2x for five on a line. It is followed by three similar creatures that draw inspiration from ancient mythology and a set of four card royals that pay less.

Visually, the slot game is as impressive as it gets. We especially liked the animations which are accompanied by guitar riffs that suit this heavy metal slot.

Champion of the Underworld Slot on Mobile Platforms

You can play the Champion of the Underworld slot on the go on any Android or iOS mobile device. No need for slot app downloads – as long as you have a stable Internet connection, you can play the slot for free or for real money from a mobile browser.

How to Play the Champion of the Underworld Slot

The first thing you need to do in the Champion of the Underworld slot is set your wager. Choose between $0.20 and $100 to start the bloody battle for the throne. The base game doesn’t waste any time introducing you to Gigablox symbols. Any symbol can appear in sizes up to 4x4, greatly improving your winning chances. The Skull Wild can step in and complete wins as it lands.

At any point in the base game, you might get the Wild Fight feature. When triggered, you’ll see Hades fight any of the premium symbols. If he wins, the symbol turns Wild. The feature includes Gigablox too.

These are the only two features in the base game, but they trigger often and they can be pretty rewarding. Of course, there’s a Bonus Round too, where the finals take place between the top combatants.

Champion of the Underworld Slot Free Spins and Bonuses

At least five Scatters are required to get access to the Bonus Round. They can also land as a Gigablox symbol which counts as several instances instead of a single one. You can gamble your way up to 20 free spins if you like. The minimum you get is five since every Scatter awards a free spin. If you try to Gamble your free spins, keep in mind that you can lose the feature.

During the Bonus Round, you get the Wild Fight feature on each spin. If Hades is successful in each fight, he claims the title and you claim plenty of Wilds. To make things even more exciting, a multiplier rises by +1 with each Hades win. A total of nine transformed symbols increase the multiplier to x3, while 11 give you an x3 multiplier.

Further transformations can get it as high as x25. Non-UK players can buy their way into the Bonus Round, paying 90x for the standard five free spins, or 1,000x for a maximum of 20.

Is Champion of the Underworld a Megaways slot?

No, it isn’t. It uses the Gigablox mechanic but doesn’t fully rely on it. It has 4,096 ways to win and a basic math model which is boosted by giga-sized symbols. You may miss the Cascades, but the other features are more than enough to make up for them.

Is Champion of the Underworld a highly volatile title?

Yes, it is. Most of Yggdrasil’s titles are highly volatile, which means you have to be careful with your wagers. By careful, we mean not maximizing them right out. Instead, start with smaller bets and build your bankroll before you risk more, and never chase your losses.

What’s the Champion of the Underworld slot RTP?

The Champion of the Underworld slot RTP is set to a flat 96%. It’s because of the features the slot offers, so the number couldn’t have gone higher. The good news is that you have plenty of specials that will make it worth your while.

How does the Gigablox mechanism work in Champion of the Underworld?

Any symbol in the Champion of the Underworld slot can be a Gigablox Symbol. These are active all the time, meaning you get them in the base game and Bonus Round. A Gigablox Symbol lands in sizes up to 4x4, creating exciting winning combinations.

How many paylines does the Champion of the Underworld slot have?

How do I get to the Champion of the Underworld slot Bonus Round?

You will need at least five Scatters to get five free spins. You can then gamble your way up to 20 free spins, but be careful – you can lose the feature too. The Bonus Round is where you can score big wins thanks to Gigablox, symbol transformations, and multipliers.

How does the Wild Fight feature work in Champion of the Underworld?

The Wild Fight pits Hades against the hellish combatants. It’s a random feature that can trigger at any time and at any point in the game. If Hades wins the fight, that symbol turns into a Wild. This is especially important in the Bonus Round as it also gets the multiplier up.

Which slots are similar to Champion of the Underworld?
