Champion of the Underworld

Yggdrasil's Champion of the Underworld is a video slot featuring a 6×4 reel layout that offers 4,096 ways to achieve wins. The game immerses players in a dark underworld arena, where Hades presides over fierce battles against monstrous foes, accompanied by an intense fantasy-horror soundtrack. A key highlight of the game is the Gigablox mechanic, which introduces oversized symbols measuring 2×2, 3×3, or 4×4. These large symbols count as multiple standard symbols when creating winning combinations.

In the base game, a random Wild Fight feature engages Hades in combat against all high-paying symbols present on the reels. Victories in these duels result in the transformation of those symbols into wilds, including portions of any Gigablox symbol. To activate the Free Spins mode, players need to land a minimum of five scatter symbols; each scatter grants one free spin, and every spin during this feature includes a Wild Fight. As Hades secures more victories in Free Spins, a multiplier counter tracks the number of symbols converted to wilds, progressively increasing the payout multiplier (×2, ×3, ×5, ×10, up to ×25) and awarding additional free spins with each upgrade.

Additionally, there is a Gamble option linked to Free Spins, allowing players who haven't reached the maximum of 20 spins to risk their Free Spins in a mini-game for a chance to gain more. Lastly, a Buy Bonus feature enables players in various jurisdictions to purchase Free Spins directly, offering either a smaller bundle or the complete set of spins.

You can try it for free in demo mode or play it for real money.
