Hellboy is a five-reel 20-payline slot developed by Microgaming and based on a comic book. The game graphics and animations are created in an authentic comic book style, which adds a unique cartoon-style touch on the slot design. Sound effects and the background sound create a spooky ambiance and fit in well with the gameplay. The video slot features a free spins round, a bonus game, a wild and a scatter symbol. The highest fixed jackpot you can grab in a regular game amounts to x10,000 your total bet per spin. The gamble feature is a classic “pick a card color” game.
