The game is played on 5 reels with 3 rows of symbols. There are 20 variable paylines with a minimum bet of 1 euro cent per line. That means you can play Hellboy from as little as €0.01 per spin, but we usually choose to play all paylines. By playing with fewer paylines you increase the variance enormously, and it was already significant.
The maximum bet per spin is €50. This way, regardless of your budget, you can enjoy this beautifully stylized video slot machine, from the time when Microgaming really did its best to make every release something beautiful.
The variance of Hellboy (that is, if you play all paylines) is medium and the theoretical payout percentage is 96.49%.

The premium symbols in the game are important characters from the comic series: of course we see Hellboy himself, but also the scientist, a lady and a bald man. The faceless man is downright scary. The premium symbols add up: 5 of the same premium symbols pay between 500 coins (for the man with the white hair) and 5,000 coins for 5 Hellboy symbols on a line.
The card symbols A, K, Q, J and 10 are the low symbols and pay out between 80 and 150 coins with 5 of the same on an active payline.
The wild symbol consists of the Hellboy logo and pays out the most: 10,000 coins.

The Scatter symbol is Hellboy's stone fist, the famous "Right Hand of Doom". 3 of these scatter symbols activate the so-called Under Water Bonus. This bonus can take a very long time, but it is definitely worth it.
To start with, the Scatter symbol already gives you a nice payout. With 2 symbols scatters you already receive 2 x your total bet and this increases to no less than 500 x your bet with 5 scatter symbols.
You will then be taken into a real comic strip, where you determine how far you get by means of picks and clicks. In a dark tunnel system, you look for the right openings, teammates and crystals. Can you make it to the end? Then there are nice rewards waiting for you in the form of cash prizes.

Supermode is activated at random times and is always good for a little jump of joy. You will receive 10 free spins where sometimes 3 random wilds are left on the screen. And those wilds are sticky for the rest of the free spins. You can even receive free spins multiple times, which can lead to huge payouts.
Graphically, this bonus is a real treat – here too you imagine yourself in a real comic strip. But one where you can win big money.
