If you like steampunk inspired slots like Gold Factory and Wild-o-Tron 3,000 then you’ll love Microgaming’s Fortunium Online slot. Pure steampunk at its best, you get to meet Maximillian and Victoria, explore a futuristic landscape and discover what lies behind the Mystery Reels.

Pros & Cons

  • Double stacked character symbols.
  • Generous prize of 800x your stake.
  • Brilliant steampunk depiction.
  • Takes a while to get used to the bonus rounds.
  • Free Spins round could be better.
  • The landscape backdrop looks better than the symbols.

How to Play

The idea behind steampunk is that it’s a Victorian world in which steam is the main source of fuel. So the world relies on it, steam powers everything and people dress accordingly. That often involves oversized goggles and leather, none of which this slot is  short of. Once you start spinning you’ll notice the lush, well-designed background, giving you a great idea of what steampunk is. Fans of NetEnt’s Wild-O-Tron 3,000 slot will know what we mean, with the result like a combination of H.G. Wells with Wild Wild West. Before you begin you’ll see the main three bonuses explained on screen, giving you an idea of what to look out for. Once you click continue, you can begin your game. The reelcase sits in the middle of the screen and is quite small in comparison to the rest of the background. The spin button is the red button to the right of the reels and if you look closely you’ll see a steampunk-designed chip/coin button. Click or tap on that and you’ll open up a menu with all the betting options. There is a Win Booster button on the left which you can use to…well…boost your wins! More on that later.


The low paying symbols are the card suits, so Clubs, Diamonds, Spades and Hearts. The high payers are retro-Victorian (so steampunk) icons, including Plasma Guns, Treasure Chests and Airships. The two characters, Maximillian and Victoria, also appear as symbols and can be stacked, which means they take up more space on the reels to help create winning combinations. Mystery Symbols are a key part of the game as they reveal a randomly chosen Wild. And speaking of Wilds, the golden W is the Wild symbol, which substitutes other symbols to create winning combos, except the Green Orb Scatter.


There are three main bonuses to look out for when you’re playing Fortunium.

Bonus Name Bonus Explanation
Mystery Symbol

During any spin the Mystery Symbol can appear. When it does, it transforms other symbols except the Scatter, into a different symbol to help create wins.

Free Spins

When three or more of the Green Orb Scatters land on the reels, you get 10 Free Spins. There’s also the chance for the second, third and fourth reels to be full of Mystery Symbols! Subsequent Scatters will give you an extra Free Spin.

Win Booster

To activate this, click on the Win Booster button on the left of the screen. For 50% of your stake, the reels will contain Mystery Symbols that only change into high value symbols or Wilds. This feature can be toggled off and on.
