What is Champion of the Underworld?
If you’re brave enough to return to the depths of the Earth, take your chance to spin the reels of Champion of the Underworld.

As you spin the underground arena machine and obtain high paid symbols, some will transform into Wilds, increasing your victories. The GigaBlox mechanic will make the payout even more spectacular, and the featured free spins mode will be further intensified by every Wild symbol, even those awarded by Wild Fight.
