Steam Tower Slot Review (NetEnt)

Steampunk mobile slots are very rare. And the NetEnt powered Steam Tower is one of them. Themed on the science fiction subgenre, it’s more than the mix of the old Victorian era and industrial design that has made it so popular.

Here’s a quick summary of what this game is made of and where you can give it a try for yourself.

Steam Tower Stacked Wild Symbols

Stacked Wild is one of the most beloved features among players.

And who wouldn’t like to see the Wild expand to all 3 symbol positions on one reel?! So to start with, the steampunk hero, who appears on the Stacked Wild, can land on any reel.

Steam Tower Stacked Wilds.

Wilds Act like Bonus Symbols

Surprisingly, both the Wild (the hook) and the Stacked Wild (the hero) act as bonus symbols.

They not only substitute for all symbols (there are no Scatters) but also trigger the promising Free Spins bonus. To win the feature you have to trigger at least one or more Stacked Wilds. You will then win 10 free games and be taken to the first round, where it all begins.

Free Spins win with increasing multiplier.
You need just 1 Stacked Wild to win 10 Free Spins.

Steam Tower Free Spins

In the Free Spins bonus, your mission is to save the princess. And guess what – she’s on the 16th floor!

To make it even more thrilling, there’s a dragon who won’t let her go without a fight. As an incentive, when you reach the top of the Victorian castle you’ll also win extra prize money, which is 1,000 coins times the bet level (coins per line). The line bet multiplier goes from 1 to 10 as usual, by the way.

But before you get to the top, there’s a lot that you can enjoy for free on the way up.

Free Spins Multiplier and Floor Meters

There are two things that are unusual about the bonus.

First of all, to help you keep track of the floor level, there’s a multiplier dedicated just for that. Secondly, there’s the Multiplier Meter. It displays the current multiplier. The Steam Punk desktop slot also has a Tower Meter on the right, which shows the current magnifier and your position in the tower. But due to design changes, NetEnt decided to get rid of it in the mobile version.

For every 3 floors that you progress the multiplier will be doubled. Here’s how:

  • Floor 1-3: multiplier x2
  • Floor 4-6: multiplier x3
  • Floor 7-9: multiplier x4
  • Floor 10-12: multiplier x5
  • Floor 13-15: multiplier x6
  • Floor 16: multiplier x7.

To ascend you need to trigger winning combos. So you won’t climb any higher if you don’t trigger any wins.

Slots with an increasing multiplier is not a novelty, even from NetEnt. For instance, you’ll see a similar Avalanche Multiplier feature in games like Gonzo’s Quest and the Pyramid Quest for Immortality slot.

Win more free spins with bonus symbols.

Win More Free Games with Wilds

The 10 freebies are certainly not enough to reach the top of the dragon tower. So it’s the Wilds that come for help once again. During freebies, for each Wild icon that you trigger anywhere on the screen, you’ll get not 1 but 2 Free Spins.

To reach the 16th floor you need at least 3 of those Wilds or 6 more free games. And because you’ll most definitely hit a dead spin along the way, you’ll need more of those as a backup.

And just so you know, Stacked Wilds don’t appear in the Free Spins feature, because the hero’s on the way to save the princess and not on the reels like in the base game.

Reach the top floor to win the top prize.


Win up to 2,000x Bet

Steam Tower is packed full of innovative developments and progressive features that NetEnt are renowned for. The Victorian era is synonymous with advancement and improvement, which reflects our own mission to drive the online casino market forward.

Simon Hammon, CPO of NetEnt

Obviously all that sounds much easier to do than it is in the real world. However, the Steam Tower mobile slot is played at a medium variance and the bonus is triggered relatively often. Ultimately, it’s the progressive multiplier and the chance to win extra spins which is why it’s become many players’ top choice since the release on 23rd February 2015.

Steam Tower was one of Mr Green’s top 3 most played NetEnt slots of 2015, among Dazzle Me and Dracula. It’s still available today for free and real money play. Good luck!
