Net Entertainment is currently previewing a brand new online slot machine called Steam Tower over at an online casino called Betsafe Casino. This is a non-downloadable slot machine which will soon be available at each of our most highly recommended NetEnt casinos and it will be available in the real money mode and in the free play demo mode.

The Steam Tower online slot machine has 5 reels and 15 winning paylines, it has a 19th Century/Victorian Era theme and it can be launched instantly in your browser. When you set the bet level to level 1 and the coin value to 0.01, you can place a bet from just 0.15 coins per spin and then when you increase both values to the maximum allowed, you can spend up to 150.00 coins per spin.

The regular Wild Symbol is the Harpoon is this will substitute all of the symbols on the reels and there are NO Bonus Symbols or Scatter Symbols. The other special symbol to keep an eye out for is the Stacked Wild Symbol. The Stacked Wild Symbol will trigger the main Free Spins Bonus when just one of these symbols lands anywhere in view. When a Stacked Wild Symbol does show up you will be awarded 10 Free Spins.

During the Free Spins Bonus, 2 additional Free Spins will also be awarded each time a regular Wild Symbols shows up anywhere in view and you will also get to move up to the next floor. Altogether there are 16 different floors. Each time you climb to a new floor, the Multiplier Meter towards the right hand side of the game window will also increase. This starts at 2X and it can climb up to a maximum 7X. You can see which level you are currently at and how many Free Spins you have left towards the bottom of the game window, just beneath the reels.

There are some really big prizes up for grabs during this bonus round and it doesn’t seem to take forever for this bonus round to trigger. If this new slot hasn’t yet arrived in your favourite UK online casino, don’t worry because it shouldn’t be too long before it does arrive. Some of the best NetEnt casinos for UK players include sites like Casumo Casino, Mr Green Casino, Betfair Arcade, Casino Euro, Ladbrokes Games, William Hill Games and Bet365 Vegas.
