Steam Tower

Steam Tower is an unusual online slot for many reasons. Firstly, its creators, NetEnt, have chosen to use the steampunk genre, and the steampunk movement takes its inspiration from an equally curious blend of modern technology, Victorian England, and steam power.

Secondly, the slot incorporates a storyline into its free spins bonus where you have to help the hero climb the tower to rescue the princess from the dragon, and the higher up the tower you go, the more free spins and win multipliers you gain. Thirdly, Steam Tower comes with a very impressive RTP (Theoretical Return to Player Rate) of 97%. And, finally, you get to benefit from two wild symbols, one of which is stacked. What's not to like?

More about the Software Provider

NetEnt has been operating in the casino industry since 1996, and has been at the forefront of online and mobile slots development for the last decade. Although the company is based in Sweden, it works with online casino operators worldwide, which it supplies with its slots, table games, live dealer games, and casino software.

NetEnt develops progressive jackpot slots such as Divine Fortune and Mega Fortune Touch, as well as video slots including Starburst, South Park, Aliens, Dracula, Gonzo's Quest, and The Invisible Man, the majority of which you can play at our casino on your desktop, laptop, tablet or mobile.

Appearance and Sound Effects

The Steam Tower forms the background in this NetEnt online slot, and although you only see the base of it in the main game, you'll get to travel up its many floors once you trigger the free spins bonus.

As clouds of steam roll along the cobbled platform on which the tower is situated, a moustached gentleman in Victorian clothing stands with his grappling hook to the left, and you can see his chest rising and falling as he breathes. In the distance, you can see an 1800's cityscape that's partially obscured by industrial smog. The orchestral music is both mysterious and exciting, and is perfectly suited to the fantasy-steampunk theme.

The reels feature the man, a princess, the steam tower, a dragon's eye, the grappling hook, and four low-value playing card symbols which are illustrated with cogs.

Bonuses and Special Features

The game uses two wild symbols. The first is the standard wild, which is represented by the grappling hook, and it can help you create winning combinations by substituting for all other symbols. The second is the stacked wild, which is represented by the gentleman, and when one or more stacked wilds cover any reel in the base game, you receive ten free spins, and the game screen moves up to the first floor of the tower.

The steam tower contains sixteen floors in total, and with a bit of luck, you'll get to see them all. In the bonus game, each floor has a win multiplier associated with it as follows: Floors 1 to 3 = x2; Floors 4 to 6 = x3; Floors 7 to 9 = x4; Floors 10 to 12 = x5; Floors 13 to 15 = x6; Floor 16 = x7. If you manage to reach Floor 16 which is where the princess is being held captive by the dragon, you also get a bonus reward of one thousand coins. Plus, every time a grappling hook wild symbol lands on the reels, you gain another two free spins, and the game ascends to the next floor.


Steam Tower uses five reels, three rows of symbols, and fifteen fixed paylines, and boasts an impressive RTP (Return to Player Rate) of 97.00%. The game lets you create winning combinations using matching symbols in succession from left to right across the reels, starting with Reel 1.
