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.

Review and recommendations from the testing team

WinningThe Steam Tower is probably the most ambiguous slot from NetEnt. Due to the stereotype that it perfectly keeps the balance, this slot is very popular with bonus hunters and players who like games on real money. Online casino owners like to add it to the list of prohibited slots for games with bonus money.

  • In the main game, the slot often gives out winning combinations, which creates the illusion of good balance retention. In fact, most of these winnings are less than the average value. The slot rarely gives out an expensive combination, so if judged solely on the main game, it can’t be said that this slot is really good at keeping the balance.
  • As for the bonus game (free spins), and for winning combinations in the main game, the slot quite often teases by giving illusions of an imminent issuance of bonus games. A bonus symbol with an enviable constancy appears on the gaming reels, and either fails to reach one cell or crosses over it. It is also worth noting that bonus games are issued with a very high frequency (probably one of the highest among NetEnt slots). During testing, it was noticed that the slot gives out bonus games in a row for a small number of spins. And after a “series” of bonuses, it stops issuing them for 300 spins or more.
  • Winnings on bonus games are, usually, not high. Getting a line of top symbols with a good multiplayer is possible once in 15 bonuses; and getting on the 16th floor is very rare, on average it happens once in 20-25 bonuses.
  • During testing on various online casinos, it was possible with the second bonus, to get a top bonus on the 16th floor. In another casino, more than 15 bonus games in a row were unsuccessful.
  • In conclusion, it can be said that this slot requires a "smart" game strategy. With a margin of 150-200 bets, it is recommended to test the slot on bonus game issuance with 50 spins. In case it is successful, do not rush to leave the slot; a whole series of bonus games will likely to start, and you have to try to figure out in time when they will end. Therefore, if after a bonus, there are no new ones for 50 spins, it is recommended to end the session.

Bonus 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:

  • Ten 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.
  • Moving from floor to floor, the multiplier (maximum x7) applied to the win, which will increase from level to level.
  • If you reached the 16th floor and you could save the princess, you will receive an additional reward, calculated according to the formula: 1000 multiplied by the player's bet level. This is the amount you get in coins, having reached this level.
  • 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 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.
