Some of you may be familiar with the subculture known as “steam punk”. It is an aesthetic that incorporates Victorian style with futuristic mechanical gadgets and also serves as the inspiration for the video slot Steam Tower. This adventure video slot features a princess that is being kept in a tall Steam Tower (get it?) and is being guarded by a not-so-pleasant dragon. Your objective is to make your way up the the 16 floors of the tower in order to free the captive princess. In order to do this you will need to use the Free Spins mode to make your way up each successive floor, and with each step closer to the Princess, the more favorable the winnings multiplier becomes.

Game Features:

  • Multipliers, Stacked Wilds, Free Spins, and Symbol Substituting Wilds
  • This is consider a “Video Slot” with a 5 reel, 3 row build that features 15 win lines

Steam Tower allows the bet level and the coin amount to be adjusted from 1 to 10 and 0.01 to 1.00 between each game round. Winning requires landing on identical symbols on one of the 15 lines that make their way from one side to the other of the reels. There is the possibility to utilize Wilds that substitute in for sybols in order to hit a winning line, and also Wilds that stack in order to activate multipliers and free spins.


Wild Symbols are highly desirable and have the possibility to to appear on any position on Steam Tower’s reels, even during Free Spins. The ultimate winning combination is when Wild Symbols overtake all of symbols.


Unlike the “symbol substituting wilds”, Stacked Wilds are not available during free spins, just during the main portion of the game. Stacked Wilds that cover the whole reel trigger 10 free spins, and also can create normal winning line combinations by subbing in for other symbols.


It is during the Free Spins mode that you will be attempting to climb each floor of the Steam Tower. The first free spin starts you on the first floor, and then your will progressively attempt to make your way up all 16. The first floor feature a x2 multiplier, and each floor after that gradually increases the multiplier amount until x7 on the 16th floor. These multipliers are applied to the winnings of each free spin and are distributed in the following:

  • x 2 multiplier: floor 1-3
  • x 3 multiplier: floor 4-6
  • x 4 multiplier: floor 7-9
  • x 5 multiplier: floor 10-12
  • x 6 multiplier: floor 13-15
  • x 7 multiplier: floor 16

If a Wild Symbol lands during a free spin, then that is what initiates you going to the next floor and also gives your two more free spins with which to attempt to make your ascent. As you make your way, there is a multiplier meter that displays while your are in the Free Spins mode that will let you know which floor you’re on and how much your free spin winnings will be multiplied. Once you reach the top floor in Free Spin mode you will receive a bonus that equals 1000x the bet level that you played with. Also, if you land on a Wild Symbols on this final level you still receive 2 extra free spins with a 7x multiplier.


Whether you like to have easy fun at a low bet level or turn it up bit with more risk, Steam Tower is an adaptable game for any desired bet level. And if you like to mix up your bet level while playing you can do that too, adjusting the amounts for each spin. €0.01, €0.02, €0.05, €0.10, €0.20, €0.50, €1.00 are the range of coin value you can choose from. Then, the bet level adjusts the stake by multiplying your coin value from either 1 to 10. The range of bets looks something like this:

Minimum Steam Tower Bet:
€0.01 coin value x 1 bet level = €0.01 coins per pay line. €0.01 x 15 pay lines = €0.15.

Maximum Steam Tower Bet:
€1.00 coin value x 10 bet level = €10 coins per pay line. €10 x 15 pay lines = €150.


We recommend also take a good look at the pay table in order to see each symbol is worth. In order to win, all you need are 3 identical symbols in a payline and you can rake in winnings for up to 5 symbols. All the symbols vary in worth, so it is fun to refer to the pay table in order to see which ones you really want to root on landing in a line.
