How the Game Plays

Champion of the Underworld transports you to a dark, ember-lit arena where the Greek god Hades reigns over a host of monstrous challengers. The game utilizes a 6x4 grid with 4,096 ways to win, set against a backdrop of ghostly spectators and heavy metal-inspired visuals. Winning combinations are formed by landing three or more matching symbols on adjacent reels, starting from the leftmost position. The high-value symbols consist of various mythical monsters, while lower values are represented by stylized card suits.

GigaBlox and Wild Fight Explained

The GigaBlox mechanic is central to every spin, causing reels to merge and create oversized symbols ranging from 2x2 to 4x4 in size. These giant blocks function as multiple individual symbols, significantly increasing the potential for multi-line wins. Additionally, the Wild Fight feature can trigger randomly during any base game spin. When active, Hades enters the arena to battle any high-paying monster symbols on the reels. If he wins the fight, those symbols are transformed into Wilds, which can also apply to entire GigaBlox blocks.

Free Spins Explained

Triggering the bonus round requires five or more scatter symbols, with each scatter awarding one free spin. During this mode, the Wild Fight feature is guaranteed to activate on every single spin. As Hades converts monsters into Wilds, they are collected in a progressive multiplier meter. Reaching specific milestones on this meter upgrades the win multiplier—starting at x2 and climbing to x25—while also awarding additional free spins at each level. For those looking for immediate action, a gamble feature allows you to potentially increase your starting spin count, and a bonus buy option provides direct entry into the feature.
