Age of the Gods: King of the Underworld Slot Review

Soaked in Ancient Greek mythology, King of the Underworld is shaping up to be another fantastic addition to Playtech’s fast-growing Age of the Gods progressive jackpot series. Depicted as symbols, Tartarus, Cerberus, and the Three Sisters of Fate lend an eerie atmosphere to both the games’ theme and the backdrop of this slot.

But if you can look past the terror and torment inflicted by these mythological creatures, the most exciting part here is the possibility of huge wins. You can either win a max payout of 10,000x your stake or one of the four progressive jackpots pooled from all the slots in this famous sequence.

Age of the Gods: King of the Underworld Bonus Features

Just like the other games in the Age of the Gods sequence, the King of Underworld slot is full of mesmerising bonus features merged with the tales and rituals of Ancient Greeks. And though there are no free spins to play with, you still have two bonus rounds stacked with rewards beyond the world of the living.


Depicted as both a deity and a dungeon for the pre-Olympian gods in Greek mythology, Tartarus is a wild symbol in the Age of the Gods: King of the Underworld slot. It substitutes for all paying symbols except scatters and bonus symbols and pays up to 10,000x your stake for the entire reels filled with this symbol.

Scatter Symbol

Borrowed from Ancient Greek and Roman mythology, Charon comes as a scatter in the King of the Underworld. He carries souls of the deceased to the world of the dead and pays up to 100x your bet for 5 scatters anywhere on the reels.

Gates of Hell Feature

The Gates of Hell bonus feature is guarded by the hounds of Hades known as the Cerberus in this game. To descend into the underworld, you’ll have to tame 3 of these delightful multi-headed dogs in just one spin.

During this feature, you must choose a door and release the lost soul. If you get the right door, the soul will award you with some big wins. But choose the wrong one with one of the Cerberus behind it, and your bonus feature will cease to exist.

Thread of Fate Bonus Feature

Three sisters, also known as the Three Sisters of Fate are here to determine the fate of every god and every mortal, including you. One of the sisters weaves the thread of fate, the other one measures it and the third one cuts it to end life.

This is what you’ll be faced with when 3 of these sister bonus symbols reach the reels at the same time. You’ll start by picking one of the spindles to cut the thread for instant cash wins with multipliers. And you’ll continue doing so until one of the threads is way too strong to be cut down at which point, the bonus feature ends.

Age of the Gods: King of the Underworld Jackpot

King of the Underworld is part of Playtech’s successful Age of the Gods jackpot series and features four progressive jackpots that you could win at any time while playing. Plus, to maximise the payouts, the multi-level jackpots here are pooled between all of the other Age of the Gods games.

RTP and Volatility

It’s good to see a slot with four progressive jackpots featuring a decent and not below average RTP, which is 96.2% in this game. The high volatility level also radiates positive vibes allowing you to land some significant wins if you can be patient enough.
