Casinos to Play Fortunium Slot

Boost your wins to survive the future

A 5×5 reel game with 40 bet lines this Fortunium slot machine takes you to an alternate future where steampunk style machines and retro reels reveal a few mysteries.

A game that isn’t made by Microgaming, but a smaller developer Stormcraft studios it is still powered by the casino game giant.

This leads to a familiar set up if you’ve ever played the hundreds of Microgaming slots online, but instead of sticking with a popular 243 ways to win or 5×3 reel format they’ve gone with the less traditional grid slot style of 5×5 reels.

Unlike grid slots like Play’n GO’s Viking Runecraft though this still has paylines, 40 in fact which are what you’ll be wanting to find your high paying chest, blimp, guns and 5 symbol high stacked characters on.

This casino slot though has a few other mysteries up its sleeve which can help boost your wins.

Stacked mystery symbols boost your base game thrills

A feature that we’ve seen put to good use in slot machine games like Quickspin’s Pirates Charm, stacked mystery symbols can show up across the five reels on a spin and will reveal wilds, high or low paying symbols.

Turn the Win Booster feature on though which is the green button to the bottom left of the reels and you’ll get wilds and high paying symbols only.

You will have to pay for this pleasure though as turning it on will increase your bet.

The combination of mystery symbols and that extra win booster in the base game can be beneficial to your odds of getting the biggest game wins. Especially as the two main title characters of the busty gun wielding beauty and the top hat wearing gent come stacked 5 symbols high.

But it’s the free spins where even more mysteries are revealed, cause as entertaining as the base game and smaller wins you can get here are it’s the free spins where you’ll win the big rewards.

Forutnium Slot Reels, Free Spins and Mega Wins

Fortunium free spins with mystery reels send your wins sky high

And by that we mean yes it’s possible to get some decent 100 times your bet plus wins here, but the free spin bonus game is actually set in the blue cloud filled skies above the city.

Triggered by finding 3 or more of the green button scatters you will be rewarded with 10 free spins.

For every scatter you find during the free spins you’ll be rewarded an extra 1 free spin.

It’s the number of scatters used to trigger the free spins in the first place that truly matters though.

  • 3 scatters = 1 mystery reel
  • 4 scatters = 2 mystery reels
  • 5 scatters = 3 mystery reels

What are these Mystery Reels? Well much like in the base game where stacks of mystery symbols can appear on any spin. Here instead on every spin you will have at least 1 whole reel full of mystery symbols.

And if you’ve got the win booster on that can include wilds and high paying symbols only, which can have a great effect on your overall win potential.

We’ve managed to trigger the free spins within about 100 base game spins or so multiple times but with only 3 scatters and 1 mystery reel active. That still led to a decent 128x our bet big win. Were we lucky maybe, but it’s still possible.

Is this Fortunium game worth a spin?

Much like NetEnt’s Steam Tower slot, which has the same style slot theme, the overall look and feel is very much a love or hate kind of thing. For us it was lacking the grandeur that Microgaming hyped it up to to be.

The high paying stacked symbols, and base game mystery reels are a nice touch over the less than usual 5×5 reel layout.

The addition of the mystery reels and the chance to get extra free spins in the free spins bonus round can add a few thrills to the game.

The only problem is that you’ll have to hit that Win Booster button and pay a little extra for it to feel like other games of its type.

Which is a shame cause as a medium variance game with a 96.47% return to player rate and up to 800x your bet max win it has potential.

Go see if this futuristic retro slot game will take your wins sky high or if you’ll be left smothered in the smog filled city below at our recommended casino site.
