Hellboy is a Microgaming poker machine based on the famous Hellboy character created by Mike Mignola. The game has a top prize of 100,000 credits and several bonus features including free spins with extra wilds.
The Hellboy logo is wild for all symbols except the scattered Fist symbols. Line up five of the wild logos and you win the top jackpot of 10,000 credits or 100,000 credits if you play max bet.
Supermode Free Spins
At any time during regular play the Supermode free games can be activated. They work in the same was as the "You are Lucky" bonuses on games like More Chilli and Lucky 88 in the fact that you don't need anything on the reels to win the feature.
One activated you get 10 free games where up to three extra wild symbols can be placed on the screen. Any wild are held in place for the remaining spins which can lead to some big pays if you get them early in the right places.
The Underworld Bonus is won by getting three or more of the scattered Fist symbols anywhere on the screen. The feature has five possible levels and you play by picking one item on the screen which can award one of three things.
Each pick either wins a credit value, all of the wins on the screen or ends the bonus. If you make it through to the last stage you get an additional win guaranteed with the last pick.
