Fortunium review

It’s been a while since we reviewed a Microgaming game, so when we came across the new Fortunium slot, we felt this was a pretty good excuse to test it out.

This game has actually been created by Stormcraft Studios, an independent game studio which is supplying exclusive content to Microgaming operators.

Fortinium slot was designed with portrait play in mind, making it ideal for mobile gaming, and also comes with some pretty cool features, including a win booster!

Keep reading our review of Fortunium slot to learn more about it and to find out which online casinos are already offering it as part of their portfolio.

Fortunium slot features

Fortunium is a 5-reel slot with 40 paylines set in the fictional metropolis of Fortinium.

The reels contain steampunk-themed symbols like guns and airships, as well as the traditional lower-paying hearts, clubs, diamonds and spades card symbols.

There are also higher-paying treasure chests and character symbols, namely Maximillian the inventor and Victoria the explorer.

These two symbols land stacked on the reels, whereas all other symbols appear double stacked.

Fortinium slot also features a wild symbol which replaces all other symbols except the scatter.

Fortunium slot base game

In the base game, Mystery Symbols that land stacked can reveal anything from wilds, low or high paying symbols, and can lead to wins across multiple paylines.

Fortinium slot Win Booster feature

To improve your chances of winning on Fortinium slot, you may decide to make use of the Win Boost feature.

The feature will cost you 50% more for each spin, and what it does is remove the low-value symbols from the Mystery symbols.

This means that all Mystery symbols that land on the reels will only reveal high-paying or wild symbols in order to yield bigger wins.

Fortunium slot free spins

Landing on 3, 4 or 5 scatters anywhere on the reels will trigger Fortinium slot’s free spins feature.

Players will get receive 10 free spins, and every additional scatter they land during this round will also award an extra spin. During each free spin you’ll also get Mystery Reels; the game awards 1, 2 or 3 of these for 3, 4 and 5 scatters respectively.

These mystery reels will contain only Mystery symbols, which come with the possibility of landing 3 fully wild reels on each spin, improving your chances of unlocking Fortinium slot’s maximum win of 800x your stake.

Fortinium slot graphics and sound

Fortinium slot has been designed as a mobile-first game, where the portrait play experience has been given priority.

You can see this when you play it on desktop, as the reel set appears to be rather small.

However, the artwork and graphics are top-notch, and the sound effects and background music complement the steampunk theme, conveying a futuristic aura reminiscent of Never Ending Story!

Fortunium slot – our Conclusion

Fortunium slot is fun to play and we loved the fact that all symbols land at least double-stacked, as well as the Mystery feature and Win Boost option.

We found that it paid out frequent wins, and liked the fact that it can appeal to both those on a budget as well as high-rollers, given the bet size options.

We recommend trying out this original game this summer if you feel like playing something that differs from the norm which also comes with a chance of winning big.
