Steam Tower online slot game

Travel back in time to the 19th century Victorian era in this steampunk-themed fantasy world full of princesses and dragons. It’s a lot to take in but the game pays out well with a multitude of free spins and stacked wilds to boost your prizes along the way.

Theme and Storyline

Climb the steam tower to save the princess from the dragon and collect increasing multipliers as you go. The industrial fantasy world of Steam Tower is evident everywhere you look from the background graphics and in-game symbols, to the free spins bonus round in which you climb the tower itself.

The dragon is a random aspect of the game but the princess needs to be saved from something all the way up in that tower, and so this all ties in with the steampunk fantasy world that the game creates. The stacked wilds and symbols pay up to 2,000x your line bet in the biggest of the base game prizes, with a lot more available if you hit the top multipliers at the top of the tower.

Graphics, Sounds and Animations

NetEnt has made a great job of creating the steampunk world with the typical industrial background, cogs and gears being used in and amongst the reels, and the characters themselves dressed up in the classic steampunk attire.

The animations kick into life when the free spins feature is activated. Watch the steampunk hero climb up to the 16th floor to rescue the princess as the dragon swoops across the screen. The soundtrack to Steam Tower is quite standard with a few small soundbites in use, but it does help to build the suspense as you try and activate the bonus round to save the princess.

The Steam Tower slot game from NetEnt has 15 paylines in total with five reels and three rows of low and high-value symbols. The low-value symbols are the Jack, Queen, King, and Ace icons. The high-value symbols are the Tower, Princess, Steampunk Man, and the Dragon’s eye. The latter offering the biggest symbol payout in the game worth up to 2,000x your line bet. The Steampunk Man offers 1,000x, the Princess 500x, and the Tower up to 300x your line bet when you land the maximum five-symbol combination.

The Wild and Stacked Wild symbols are the bonus symbols within the game and these are represented by the crossbow-style weapon and the full character icon of the Steampunk man. All of the game’s bonus rounds are based around these symbols with the free spins and multipliers activating when you land them on the reels. We’ll explain these in the next section. 

Bonuses and Free Spins

The Stacked Wild is the main symbol that activates the free spins bonus round and you only need to spin at least one fully stacked wild to trigger the 10 free spins. You’ll start out on the first floor and you’ll then move up the floors and gain bigger multipliers with each spin. You can keep track of your floor and multiplier amount by checking the Floor Meter and the Tower Meter icons underneath the reels.

If you spin at least two of the standard Wild symbols during the free spins then you’ll be rewarded with two extra spins and you’ll also move up a floor. If you make it to the top of the tower then congratulations, the princess is saved. But more importantly for you, there is also a 7x multiplier and a cash prize of 1,000 coins multiplied by your line bet available to win. This can potentially lead to some huge payouts that is most certainly worthy of taking down any dragon! 

Bet sizes, RTP and Variance

The minimum bet per spin is €0.15 and this increases up to €150 per spin for the high stakes players amongst you. The RTP of the slot game is set to 97.04% with a medium variance. You should find a nice balance of cash prizes and access to the bonus round in Steam Tower, with multiple chances to try and reach the top of the tower over a longer gaming session.


Steam Tower looks and plays like a typical NetEnt slot game. The graphics and animations are rich with detail and the bonus round animations offer just enough to give the game some variety. The bonus feature is standard in its design but the payout potential does make up for it if you reach the top of the tower and save the princess. The extra cash 1,000x payout in the feature is a nice touch and anyone who enjoys the Steampunk movement should get enough enjoyment out of the game.
