Welcome to Fortunium™, the golden city of opportunity and adventure!

A world of mechanical marvels and alchemical wonders awaits you in Fortunium™, the new online slots game from casino games industry legend Microgaming, available to play at Jackpot City Casino. Fantasy lovers will love this steampunk-inspired game, which puts a Victorian spin on the traditional online slot game.

This new entry in Microgaming’s range of mobile slots games contains towering stacks of Mystery Symbols, which fill the reels with randomly selected High, Low, or Wild Symbols. Players can enhance their wins by activating the Win Booster™, a special device that powers up Mystery Symbols.

The adventure begins in the Base Game, where super stacked Mystery Symbols reveal a randomly selected Wild, Low, or High Symbol, allowing for big wins across multiple lines.

Amazing Game Features


This game features 40 fixed paylines. All wins pay left to right, except the Scatter Symbol which pays in any position. All wins are multiplied by the bet per line except the Scatter Symbol. Only the highest win is paid per line.


Scatter Symbol wins will multiply by the total bet staked, not including Win Booster™. Scatter wins will add to line wins. The Scatter Symbol will pay in any position.


The Wild Symbol will substitute for all symbols except the Scatter Symbol, meaning your chances of landing a larger payout increase.


Both the High 1 and High 2 Symbols are stacked 5-high in Base Game and Free Spins. All other High and Low Symbols are double stacked.


Mystery Symbols open to reveal a random Wild, Low or High Symbol. They are stacked in both the Base Game and the Free Spins.


Landing 3 or more Scatters during the Base Game triggers 10 Free Spins.

Every spin, up to 3 Mystery Reels™ may appear – 3 Scatters trigger 1 Mystery Reel™, 4 Scatters trigger 2, and 5 Scatters trigger 3. These special reels appear every spin, and are loaded with never-ending stacks of Mystery Symbols, meaning you have a chance for even bigger payouts.  

Plus, landing Scatters during the feature will extend the Free Spins experience. Every Scatter you land during the Free Spins round nets you an additional spin!

Boost Your Wins with the WIN BOOSTER™

Up the ante with the Win Booster in Fortunium™, which not only boosts your bet by a whopping 50%, it also upgrades your Mystery Symbols, enhancing them to only reveal Highs and Wilds. Any boosted Mystery Symbols you land in the base game will carry over into Free Spins and stay boosted for the whole feature!
