Hellboy Slot

If you like slots with a bit of grit and a comic-book look, Microgaming's Hellboy is one of those titles that's lasted surprisingly well. It's based on a famous character from Dark Horse Comics — a demon who smokes cigars and still has a soft spot for people — and it mixes humour and toughness in a game with 5 reels and 20 paylines. No, it's not the newest or most exciting release, but there's something charming about how simple, direct and full of features it is. There are lots of exciting features in Hellboy, like Super Mode Free Spins, the Underworld Bonus, and a Gamble feature.

Hellboy slot review - Microgaming's comic book classic with big wins and bonus action!

The slot game based on Hellboy successfully captures the look and feel of the comic book. The art style is bold and slightly gritty, with thick outlines, bright colours, and a soundtrack that feels like it came straight out of a superhero movie from the early 2000s. You'll see familiar characters from the Bureau for Paranormal Research and Defense (B.P.R.D.): Liz Sherman, Abe Sapien, and Johann Krauss. They are all there with our red-skinned antihero.

What makes Hellboy different from a lot of older Microgaming slots is how much it focuses on its theme. It doesn't just slap on a logo and be done; everything — from the background animations to the bonus rounds — feels connected to the story. The idea is that you're fighting through underworld tunnels and uncovering ancient relics, rather than just spinning reels.

Hellboy is one of the high rtp slots from Microgaming with 97.00% RTP.

Hellboy plays on a 5x3 grid with 20 adjustable paylines. You can technically play with fewer, but most players stick with all 20 — it's where the balance between how often you win and how much you could win is really felt.

The game is set up in the classic Microgaming style: you can choose the coin size, the number of coins per line, and how many lines you want to be active. You can then press Spin, Bet Max, or set it to Auto Play if you don't want to have to press buttons. There's even a Gamble feature where you can try to win more money by guessing card colours or suits — but remember, it's all based on luck, so use it carefully.

Wins pay from left to right, and the game's Wilds and Scatters make things more exciting:

  • The Wild (Hellboy logo) substitutes for everything except scatters - and it doubles any line win it helps create. The Scatter (Right Hand of Doom) pays anywhere and triggers the Underworld Bonus when you get three or more.

That's the basic rhythm: steady wins in the base game with the promise of either a random Super Mode or a triggered Underworld adventure.

Hellboy slot bonuses: Free Spins, pick game and gamble feature

This is where Hellboy really shines. It doesn't give you ten different ways to play; instead, it offers a small group of 3 bonus features that make the gameplay fun and surprising.

Gamble Feature

After any winning spin, you can gamble your win to try and make it bigger. It's simple:

  • Guess the colour of the card (red or black) to double your win.
  • Guess the suit of the card (hearts, spades, diamonds, clubs) to quadruple your winnings.

If you're wrong, you lose that round's winnings, so it's a risky but potentially very rewarding mini-game.

It's a fun little extra for those who like a thrill between spins, but most players just use it as a distraction rather than a strategy. If you're having a winning streak or playing it safe, it's often better to just collect your win and keep spinning.

Underworld Bonus Game

Underworld Bonus Game

This feature is triggered when you get 3 or more Right Hand of Doom Scatters anywhere on the reels.

After that, you are taken underground — literally. You'll explore four levels of tunnels, picking doors as you go. Behind each door, there might be:

  • A coin prize
  • A "Win All" symbol (which collects everything from that level)
  • A "Blocked" symbol will end your run

If you make it through all four levels, you will reach the Chamber of Fire. There, you will find the Relic of Power and win the biggest prize. If you survive the full journey, you can win up to 33,600 coins.

It's a classic Microgaming-style pick feature — simple, suspenseful, and surprisingly rewarding when you're lucky.

Super Mode Free Spins

Super Mode Free Spins

Super Mode activates randomly - you don't need to get specific symbols or combinations to trigger it. When it activates, you get 10 Free Spins, and during those spins, up to three positions on the reels become Sticky Wilds.

Those sticky wilds stay fixed for the whole round, and since Wilds also double any line wins, they can win you some seriously satisfying payouts. The only catch? Super Mode can't be retriggered. You get 10 spins for each time you activate it, and because they're random, every base spin feels a bit exciting.

Hellboy is one of the high rtp slots from Microgaming with 97.00% RTP.

How to get the most out of the bonuses on the Hellboy slot

Let's be honest — you can't "beat" a slot. You can play in a way that makes it more enjoyable and lets you play for longer (and maybe get more chances to try out those features). Here are some smart tips that will help you:

  • Keep all 20 paylines active. The game's designed for it, and playing fewer lines will only reduce the number of times you hit the win. Stick with 20 and change the size of your coin instead.
  • Manage your money. Super Mode activates randomly, and Underworld requires Scatters, so both features depend on the volume. Try playing the slot for at least a few hundred spins if you can. That's how it's meant to be played.
  • Let Sticky Wilds do their thing. In Super Mode, early Sticky Wilds can turn into big lines later in the round. Don't change it or try to force it; just let it happen.
  • Use the Gamble Feature Wisely. It's tempting to double up every win, but that's how you end up losing your money. Treat it like a spice, not the main course — an occasional adrenaline hit.
  • Understand the pace of the game. The Hellboy slot is not very unpredictable. It has a medium variance, which means you'll win small amounts regularly, as well as occasionally winning a lot. It's steady, not up and down.
  • Set Limits. Super Mode can appear at any time, so it's easy to get stuck trying to get it. Set a time limit and stick to it.

A comic legend meets the reels - why Hellboy still rocks!

Hellboy is one of those slots games that keeps on being fun years after it came out. It's not the most exciting or modern, but it has character, a good range of features, and a theme that feels well-planned.

If you like the world of comic books, or you're just looking for a slot with some nostalgia and decent payout potential, Hellboy is still a great choice. The random Free Spins keep things interesting, the Underworld Bonus adds a fun adventure element, and the Wild multiplier makes the base game exciting.

The main point is: The Hellboy slot game by Microgaming is a cult favourite that always delivers fun, drama, and excitement.
