Steam Tower is a 2015 NetEnt slot with a steampunk theme and a progressive bonus game in which you reach levels on the Tower to win better multipliers, up to 7x on level 16!

This 15-payline game asks for a long playing session but will be very rewarding on high Tower levels.

Steam Tower introduction, including RTP and variance

Steam Stower’s design is gorgeous: the Steam Punk theme looks great and our bearded hero, together with his grappling hook, has an instant likeability factor.

The theoretical return to player (RTP) of Steam Tower is 97%, which is excellent and is the best feature of the game along with the progressive bonus feature.

The variance can be best described as medium. It is quite easy to trigger the free spins bonus feature, but it might take some tries to get some good wins out of it.

Steam Tower gameplay and paytable

Steam Tower only has eight symbols, four of which are low-paying card symbols and four are main symbols with steampunk artwork, and they don’t appear on the reels very often. There are a Wild symbol and a Stacked Wild that’s three symbols high, and that triggers the free spins game.

There’s nothing much to do in the base game in Steam Tower. This is one of those slots where you’ll just be waiting for the free spins game, and the base game is best played on Autoplay as Steam Tower demands longer playing sessions.

The best rewards will come after you reach a high level on the Tower, and this might take several attempts.

It’s important to note that the prize of reaching the top of the Tower is 1,000 coins multiplied by your bet level, so make sure the bet level is 10.

Bonus Features

The only goal of Steam Tower is to trigger the free spins game by landing a full Stacked Wild symbol on one of your reels. The next mission: to reach the top of the Tower and rescue your girl. When you enter the bonus game, you’ll start on level 1, and you advance upwards by landing Wild symbols on your reels. Every time you land a Wild, you will move up a level and will also get +2 free spins.

Floors have different multipliers, 2x on the first three floors, and then the multiplier increases by 1x for every three levels.

Even climbing halfway up the Tower can be very rewarding, and anything beyond that point means you’ll get ahead of the game and will make money on the Steam Tower slot.

CasinoWizard’s verdict: 3 out of 5 stars

Steam Tower is an excellent game if you have the time to wait for numerous attempts at the free spins game to finally reach the top of the Tower and get that 7x multiplier and a 1,000 coin reward that comes with the top level.

It’s an excellent low to medium-variance slot game for players who enjoy slots of this type, especially those who like progressive games where there’s something to do and some progress to look forward to.

And there are many such players, as proven by the popularity of Steam Tower!
