Microgaming responds to a recent fad in online slots, namely the tsunami of superhero-themed online slots hitting the internet, with its Hellboy slot.

Hellboy is a solid play in the reliable Microgaming mold, with reel play nothing mind-blowing – characters include members of the Bureau for Paranormal Research and Defense and poker run – together with an involved, high-paying, high-concept bonus round.

The "Underworld Bonus" is triggered by three to five SCATTERs and comes with a heavy mission “to locate and secure the hidden relic of power guarded by ferocious beasts." There’s also something about finding team members and completing all four levels to reach the chamber of fire and claim your relic. Our advice: Forget the instructions, collect your dudes and run like hell(boy).

There’s also a random “Supermode” which triggers 10 free spins with all the requisite payouts there.
