Steam Tower Game Overview

This medium variance slot game has a max win amount of £300,000 and fifteen bet ways. The bonus features are scarce but add to the theme in a big way. The floor meter is your ticket to some bonus spins and a multiplier boost.

Before we get into that, let’s figure out the basics. But remember to sign up to play casino online right here at King Casino.

How to Play Steam Tower Slot

We won’t need to wrack our brains too much to learn how to play Steam Tower. The basic gameplay requires us to form pay lines. How do we do this? Follow the process below to get caught up.

  • Step 1: Set the bet level. This bet level represents the number of coins you will wager per line, and there are fifteen pay lines.
  • Step 2: Select the coin value. Each coin is worth a 1p wager. The max bet in Steam Tower is £150 for a single spin.
  • Step 3: Spin the reels and wait for the animation to end. Players can speed up gameplay by using the max bet feature. Click this button to instantly bet the max amount and spin the reel.
  • Step 4: the game will calculate any wins once the reels stop. A win is comprised of a pay line that includes three or more identical symbols across adjacent reels.

In addition to the regular paying symbols, wilds will substitute regular symbols for larger wins and scatters can trigger the bonus features. So, what types of symbols can we expect in the Steam Tower slot?

Design and Symbols

The five reels in Steam Tower are plopped down in an industrial part of Victorian London. The characters next to the reels include a dapper gent in a top hat and a lady in a corset.

The Steam Tower graphics are the normal 2D level found in most NetEnt slots, and the symbols are relatively themed. These symbols include these two characters, worth a 7x multiplier for five across a pay line, and some lower-paying card symbols. There are a few extra coin stacks and a dragon’s eye symbol used to make up the numbers, but most players will not ignore the copper reels or the sound or gears turning.

The Steam Tower slot is delightfully steampunk in every sense of the word, a nice addition to NetEnt’s catalogue, which already includes:

Steam tower Bonus Spins and Special Features

The Steam Tower bonus features are few but involved. It sounds like an oxymoron, but the Steam Tower slot centres most of its action on a tower system. There are sixteen floors for the player to climb, and you achieve this by using:

  • Bonus Spins: land a stacked wild to trigger ten bonus spins and a trip to the 1st The only way to climb the tower is by landing the grappling gun symbol on a bonus spin. This symbol also gives the player a further two bonus spins. Run out of bonus spins, and you will be taken back to the bottom floor. Reach the 16th floor to receive a pay-out of 1,000 coins. The top floor wins also come accompanied by an extra 7x multiplier boost.

Players will spend a lot of time in the Steam Tower bonus spins round trying to climb the tower. It might be the only bonus feature, but it covers a lot of gameplay.

Return To Player

Return to Player (RTP): 97.04%

RTP is used to explain the potential money that an online slot or casino game can pay back to players. It appears as a percentage and is generally calculated from gameplay over a long duration of time.

For example, if a slot has a RTP of 97% this means that it could pay back £97 for every £100 wagered.

However, there is no guarantee that players will receive this amount, as slot payouts are entirely random.

Is this slot worth playing?

The cartoony nature of the Steam Tower slot might give you pause if you are a high roller. Don’t be dismayed; however, the max bet amount in this slot is £150 per spin, and the variance is medium. A medium variance slot is just as likely to feature low-value pay lines as it is high-value lines, making it all the riskier when betting high. On the other hand, the minimum bet amount is just 15p, so there are plenty of chances for players that like a relaxed slot experience.

Sure, we’ve already mentioned the lack of bonus features in Steam Tower, but the RTP rate is extraordinarily high at 97.04%. This percentage is a full 1.04% above the average for online slots in 2021 and leaves the online casino with a house edge of just 2.96%.

It is hard not to recommend the Steam Tower slot game from NetEnt. The tower climb aspect of the bonus spins is worth a try on its own and adds an additional objective to proceedings. However, don’t just take our word for it. Try Steam Tower at King Casino to see what you think of this old-timey slot.
