And while the game features with the multi-level system at first may bewilder some players, at its core Steam Tower is still a fairly simple game. To get started playing it, you first need to find a casino, create an account and charge it (or you can play a demo) and then launch the game. Afterwards simply:

  • Click the wrench icon to open the settings menu of the Steam Tower
  • Also, necessarily read the game rules, about the game rules and the value of symbols. To check out this info press the question mark symbol and the "i"
  • Afterwards, you can adjust your total stake (where the lowest is €0.15 and the highest is €150) and the level at which you want to start at. Note that the higher the level the higher your steak will be, but with a higher level you get more valuable prizes
  • To start playing, press the green spin button, or activate the autoplay mode. Best of luck!

Quite an epic slot. I got WW1/industrial revolution vibes from it. That’s how NetEnt pictured steampunk. Well done, I guess.
The game is a tough cookie gameplay-wise. It’s not that simple or predictable. I’m talking mostly about FS with all those meters/levels. U just never know the outcome of very next spin – will it be empty or bring mega win.
I wouldn’t call the slot very volatile, but it’s hard to imagine a profitable session without FS. And it can take some time to trigger freebies.
