Stacked Wilds

The engineer is one of the game’s 2 wild symbols. When he appears in a fully stacked formation and fills the whole of a reel, you’ll go on to trigger the free spins feature.

Free Spins

Once triggered by the stacked wild engineer, you’ll go on to play a minimum of 10 free spins. These play out as if you’re riding an elevator up the Tower.

The round starts on the first floor with a 2x multiplier active. The goal is to get higher up the Tower. Each new level you reach increases the value of a win multiplier.

Hope to see plenty of grappling hook wilds during the free spin round. Each time one of them lands, you’ll move up 1 floor of the tower. A further 2 free spins are then added to your total.

You can keep tabs of where you are courtesy of the Floor Meter, Multiplier Meter and Tower Meter.

Multipliers can get as high as 7x if you make it all the way to the top of the Tower and the 16th floor. If you make it to the summit, you’ll also receive a bonus of 1,000 coins.

Design, Theme and Visuals of Steam Tower

steam tower slot basegame

Despite being launched back in 2015, there’s still a fresh, modern look to the design in Steam Tower.

With the base of the Steam Tower, pipes, mechanisms, and a cityscape in the background, there’s a real industrial quality to the design here.

The reels are made up of mechanical playing card symbols which appear alongside the summit of the Tower, a princess, the whiskered engineer, and a dragon’s eye. The symbols are packed full of impressive detail. The fantastically catchy soundtrack is an ideal match for the steampunk theme on display here.

NetEnt has a reputation for creating some of the best-designed slots in the online casino world and with releases like Steam Tower, it’s easy to see why.
