Steam tower online slot

The 23 of February in 2015 was the official release of a new Steam Tower video slot from NetEnt company. The plot is based on the fantasy style, which includes elements of the technical revolution of the Victorian era. Your main task will be to climb the 16th floor of the steam tower to perform a noble deed and save the princess from it, in appearance she is very similar to Rapunzel. For such a bold action, you will get a serious reward. In addition, the available profitable features (free spins and stacked wild symbols) only increase your chances of the serious victory. In this material, we will not only give you a detailed overview of the machine, but also you should pay attention to the features that are available to it. As you see, this online slot is devoted to those who consider themselves as the heroes. Furthermore, the game will give you minutes of joy and delight, guaranteed to distract you from the grey routine and everyday problems, and also give you the opportunity to make good money.

Feedback of the tester's

I suggest the bonus hunters play with care at this video slot; this slot machine has middle range points - 5,92 out of 10. It does not always keep the balance perfectly. Usually, it is on fire or just taking your money away. Statistically, the free spins feature falls often, every 77th spin (statistically, 1,30%). My average payout was 37x my bet in the feature. More than a third of the spins turned out to be the prize spins. And besides, 54% of the pool will go for payments in the usual spins. You can use the following strategy: try to gamble with low bets and if you see that machine is on fire - increase the stakes. Otherwise, close it.

Description of the video slot

Steam Tower comes with five reels, three rows of symbols and 15 constantly active pay lines. You cannot change them. However, you can always identify what amount to put on each spin. If you want to do this, you will need to set the stake level (from 1 to 10) and any of the seven available values of the coin (from €0.01 to €1). Thus, the minimum allowable bet will be €0.15, and the maximum will be €150.

One of the main zest is the bonus game, which should be paid attention in the first place. During it, you will try to get to the last 16 floors to save the princess. There you will receive a reward of 1000 coins multiplied by the bet level, and additional multipliers (up to x7) for all remaining free games and our hero will have a real chance to do it.

Due to the use of modern technologies, the game is adapted for all mobile devices, and you have the great chance not to interrupt and continue playing. In our view, the Steam Tower slot can be considered balanced, with average volatility. The maximum winning to which you can count is 300,000 coins, and the theoretical percentage of the return is declared at 97%. It is a high percentage which will help you increase your fortune. We recommend playing the demo version of the slot for free and without registration.

Symbols and payouts

In addition to the eight basic symbols, the pay table offers us two special symbols. Unlike most other slots, here you will not find a scatter, but there are just two Wild signs, one of which will be stacked.

Four card symbols (from jack to ace) are low-paid. They appear quite often on the screen, and they often make the pay combination, compensating for low payouts. Princess, the hero, the top of the steam tower and eyes of the red dragon are symbols of higher value.

  • Red Dragon's Eye brings from 40 to 2000 coins
  • The hero is estimated from 30 to 1000 coins
  • Princess will be pleased with payments from 25 to 500 coins
  • Top of the tower will increase the winning from 20 to 300 coins
  • Card marks will bring from 3 to 150 coins
  • The winning on the active pay line is paid in the case if the endless combination of identical symbols begins with the leftmost reel and it consists of 3, 4 or 4 images. You are paid only the highest payout the stake on the pay line. If the pay combinations fall out on several active pay lines, then the winning will be summed up. More detailed information is provided in Rules of the Game.
  • Wild symbol. The traditional wild symbol (harpoon) appears anywhere, as during the usual spins, and during the bonus round. It does not bring independent payments but replacing any other symbols to form pay combinations.
  • Stacked Wild symbol. The image of the primary symbol on a green background is a stacked wild symbol, which in this case also has the role of scatter, starting free spins. Its appearance even possible in any place and it covers itself at once with the whole reel.

Bonus games and features

We appreciated how the bonus function in the form of free spins is realised at the machine. Let's look at it in more detail:

  • WinningTen free spins are started falling out 1 or more stacked wild symbols of in the usual spins.
  • If you want to go to the next floor of the tower, you will need to put a harpoon symbol on the reel that makes Wild symbols.
  • For every badge of the harpoon, you will get two free spins.

  • Further free spins will be performed by using a multiplier of x7.
  • During free spins, all winnings are multiplied by the multiplier, depending on which floor you are on. Free spins pass with the same level of the stake and the nominal value of the coin, which triggered them. The first spin always takes place on the 1st floor.


We suppose that this game looks beautiful with an exciting and innovative topic, funny symbols and great graphics. Moreover, it provides many opportunities to receive the generous payments during the original free spins that can be extended. Do not forget about the high percentage of the return of made bets. In one word, this slot has everything to play necessarily in it at least once.
