The Hellboy slots game is loosely based on the Dark Horse comic book series of the same name. If you're only familiar with the Ron Perlman movie version, you may be disappointed. Like all comic-themed projects, there was a lot of money riding on this Microgaming game and the design team was free to make everything at the absolutely highest level.

Also, knowing that it represents more than just a simple slots game, they couldn't cut corners to maximize profit. Every feature is present in this game, and even the hidden bonus game is several times more extensive than what you are probably used to.

The end product, not surprisingly then, is really what all slots games should aspire to be. If you have any interest at all in the theme, then the Hellboy slot machine should be right at the top of your list of things to try. Read on as we review the entire game.

• Play 20 paylines for real money
• Lots of action-packed bonuses on offer
• Hit the Super Mode and give the game a try at the best casinos

Hellboy Design and Gameplay

Hellboy slots uses a simple 5-reel, 20-payline design. It's flexible yet focused. You can choose to wager one to ten coins on each line and their values span all the way from a single penny to 25c. This puts the minimum bet at just 0.20 while you can potentially put 50.00 on the line by wagering two hundred 0.25 coins.

Out of the many special features offered up by Hellboy online slots, the simplest is the wild symbol: the Hellboy Logo itself. It can substitute for nearly any other symbol to make a winning combination. The only exception to this is the Fist symbol. This is the game's scatter symbol.

Scatter symbols are those symbols that can create winning combinations even when they don't land on the same payline. Instead, they just have to be on the display when the reels come to rest. In the case of the Fist symbol, you only need two of them to appear at once to receive a payout, though receiving more (up to five in total) will land a bigger payout. These prizes are worth 2x, 4x, 25x, or even 500x your total bet, for two, three, four, or five symbols, respectively.

Claim Your Hellboy Bonuses

The Hellboy slot machine has a cool bonus that takes you on a journey through the Underworld. Your success determines how far you will make it. When you see three or more Fist symbols, you will be taken to the Underworld Bonus Game.

First, select one of the five doors and watch the result. Monsters may come out to attack you, which is fine because you're going to shoot them down and get points each time you do so. Alternatively, you may find a friend and also receive points. Finally, you may find a blocked door which marks the end of the game. If you don't hit blocked passages, you can potentially cruise through four levels.

You can also be randomly-launched into Super Mode, which means you get ten free spins with up to three positions that will be locked as wild symbols for the entire bonus round. No matter how you are playing, though, each win will take you to a basic double or nothing (and quadruple or nothing) bonus game. Guess the color of a random card to double your winnings, or the suit to quadruple them. If you're wrong, though, you will lose everything!

Mobile Options for Hellboy

Hellboy plays superbly well in a mobile web browser. It hasn’t been HTML5-optimized yet, though, so you’ll have to make sure that you have the latest Adobe Flash working. That’s easy to do though and just takes a few minutes before you’ll be spinning away.

Our Verdict: Hell...yeah!

Hellboy is a great Microgaming slot that players will come back to time after time. There’s certainly a lot on offer here for slots and comic book fans alike. If you're a fan of big comic book adaptations, check our Amaya/Cryptologic's series based on the DC Comics. Games like The Flash, Wonder Woman, and Superman take a leaf (literally) out of the classic 1940s comics. They all feature some killer bonuses to boot.
