Hellboy is a five reel online slot game centred on the comic book hero of the same name. The game is a Microgaming creation with two bonus features and 20 pay lines. Hellboy was made into two feature films but the graphics and visual effects of the online slot are based more on the comic.

Symbols include the best known characters from the Hellboy franchise. Hellboy himself is the wild symbol and substitutes the standard symbols if a win is possible. He won’t substitute the scatter though. The standard symbols include Abe, Krauss, Liz, Professor Bruttenholm, a bad guy and the typical 10, jack, queen, king and ace online slot symbols. The most valuable symbol is the logo which pays out up to 10 000 coins for five on a pay line.

The betting options are varied and allow an amount of up to 10 coins on each pay line. The coins are able to be set at various values that start from as little as the value of 0.01 and include values of 0.02; 0.05; 0.10; 0.20 and 0.25. Both expert mode and auto play options are available.

The Underworld Bonus Game Feature

When Hellboy was born his father gave him the right hand of doom which is his well-known red stone forearm and hand. In Microgaming’s online slot game the symbol featuring the right hand of doom is the bonus symbol that triggers the Underworld bonus game feature when three or more show up on a spin.

The objective of this bonus game is to reach the Chamber of Fire and ultimately claim what is referred to as the Relic of Power. There are four stages to get through and the goal is to avoid being confronted by demons and landing up in blocked passages. Demons do allow for progression through the stages but the blocked passages are what ends the bonus game.

Each level allows only one pick of a passage and progressing beyond the fourth stage is when the Chamber of Fire is reached. Here the goal is to shoot at a crystal which will reveal the relic of power and award a random prize.

The Supermode Bonus Game Feature

The Supermode bonus game feature is a randomly triggered Hellboy online slot bonus. When this feature is triggered a total of 10 free spins are awarded.

The free spins are played immediately and on the bet level that was in place when the random feature was triggered. During the feature a player may receive up to three Hellboy sticky wild symbols that remain in their position until the last free spin is played.

The Hellboy Online Slot Gamble Feature

Hellboy has a typical gamble feature for online slot games. Clicking on the gamble button below the reels activates this game which can only be done after a win occurs.

The amount won is what can be gambled in the hopes of doubling it up. The aim is to make a correct guess as to whether a face down playing card that will be revealed is going to be red or black. There is a limit of five correct guesses in a row.
