Game rules

Your objective in Steam Tower is to help the inventor climb to the 16th floor of the tower, rescue the Princess from the dragon and help yourself to a huge cash payout in the process. There are 16 levels in the bonus round, with increasing Multipliers that go up to 7x, for some big wins if you make it that far!

Steam Tower symbols

Polished metal playing card icons are joined on the reels of Steam Tower by higher-paying symbols representing the tower itself, a beautiful Princess, the inventor and a dragon’s eye. This latter pays up to 2000x your payline stake for five-of-a-kind matches, so you’ll be hoping to see it lining up in your favour across the reels.

There are also two Wilds, both of which stand in for all other game symbols. The grappling gun Wild occupies just one space in the grid, but it’s the inventor Wild, stacked three symbols high, which you’ll be trying to land. If you can manage to make him fill an entire reel you’ll be rewarded with the Free Spins Bonus round.

Min/Max wagers & lines

With 15 fixed paylines, 10 bet levels and a coin value ranging from 1p to £1, Steam Tower has wagering options from 15p to £150 per spin. That puts the game within reach of all types of slots fans, although lower-stakes players should definitely explore Steam Tower demo spins before risking real cash.

Steam Tower free spins

Landing the inventor Stacked Wild fully in view triggers the exciting Free Spins Bonus feature, with six levels and an increasing Multiplier worth up to 7x. Now the inventor must climb the tower to rescue the Princess from the dragon, and as he progresses to each level a Multiplier increases too.

• Floors 1 - 3  =  2x Multiplier
• Floors 4 – 6  =  3x Multiplier
• Floors 7 – 9  =  4x Multiplier
• Floors 10 – 12  =  5x Multiplier
• Floors 13 – 15  =  6x Multiplier
• Floor 16  =  7x Multiplier

Spinning up Wilds awards two additional free spins and allows the inventor to climb to the next level. Reach the top at level 16, and the Princess is freed, awarding you an additional prize payout of 1,000 coins multiplied by your payline stake.

Animation, graphics, and soundtrack of Steam Tower

Steam Tower starts out as an above-average online slot, with incredible graphics and a movie-style soundtrack. But it’s during the Free Spins Bonus that the game really comes into its own, as the inventor uses his grappling gun to climb the tower and rescue the Princess.

NetEnt really excels at these unique and atmospheric bonus rounds, and this is a feature that will keep you spinning the reels in the hope of making it to the top. It’s well worth spending some time playing Steam Tower demo games, so you get a feel for how often the bonus feature is triggered – and how well your bankroll might cope!

Steam Tower RTP and volatility

The Steam Tower slot RTP is well above average, coming in at an impressive 97.04%. That doesn’t mean you’ll win back that percentage of your expenditure though, no matter what you might have heard. Steam Tower RTP, or Twin Spin slot RTP, the only takeaway from this statistic is the house edge, which is slightly below 3% for this particular game.

Steam Tower is a medium volatility game, meaning big wins will be few and far between, whilst smaller wins won’t cover the cost of the spin. That’s why it’s such a good idea to try some Steam Tower free play games before playing with real cash. You might not be able to grow your bankroll playing Steam Tower demo games, but you won’t see it disappear either!

Steam Tower verdict

NetEnt are renowned for creating some of the most entertaining slots games UK fans have ever played, and Steam Tower certainly lives up to the hype. Fantastic graphics, an atmospheric soundtrack and a breathtaking bonus feature will keep you spinning the reels, as you battle to reach the top of the tower and land those big payouts. There’s no guarantees about how often the bonus feature will activate though, so it can be all too easy to keep on playing, even when your bankroll suggests it may be time to stop!

We strongly advise trying as many Steam Tower free play spins as you can, to get the measure of the gaming mechanics, before trying your luck playing with real cash at one of our top recommended casinos.
