RTP Champion of the Underworld is a six-reel slot from Yggdrasil with 4,096 ways to win and a high-volatility structure. Set in an underground arena, the game features Hades and four monsters, with high-paying symbols that can turn into Wilds during play. The RTP is listed at 94%.
The main mechanics centre on the GigaBlox feature and Wild Fight, both designed to affect winning combinations and bonus outcomes. Free spins form the main bonus round, with each Wild symbol helping to intensify the feature, including Wilds awarded through Wild Fight. Players can also gamble their free spins using two volatility levels.
A demo version is available for those who want to play for free and practice before playing for real money. The slot can also be accessed through a buy bonus option, which gives direct entry to the free spins feature.
