Steam Tower Slot

Visual Notes

Steam Tower is a video slot from NetEnt, with a release date of February 2015. The game uses a steampunk theme, mixing Victorian London imagery with brass machinery, smoke, and comic-style characters.

The graphics look strong for an older NetEnt slot. The backdrop is detailed, the reel frame suits the industrial theme, and the engineer fits the setting better than the princess. The animations are polished, and the metal-and-steam sound design works well, though the music loop can wear thin.

The Steam Tower slot is a stand-alone title and part of no wider NetEnt series. Compared to many newer games, this online slot has a more fixed visual style and a more old-school presentation.

Game Mechanics

The Steam Tower slot machine is a steampunk game with stacked wilds and free spins. Its bonus climbs through tower floors and raises multipliers as you go. Compared with many older feature-led slots, its main strength is the clear sense of progress.

Symbols

The symbol set is split into clear tiers.

• Low-value symbols: J, Q, K, A
• High-value symbols: Tower, Princess, Engineer, Dragon Eye
• Special symbols: Wild (weapon icon), Stacked Wild (engineer icon).

I find the symbol ladder well judged. The base game can feel a bit flat between features, but the wild rules give the bonus round enough lift.

Bonus Features

The Wild is shown as a weapon icon. It substitutes for regular symbols. During free spins, any wild landing anywhere on the reels adds 2 extra free spins and pushes the game up to the next floor until floor 16 is reached.

The Stacked Wild is the full-reel engineer symbol. In the main game, one or more stacked wild reels trigger 10 free spins and move the bonus to floor 1.

The bonus round is where Steam Tower gets most of its character. All line wins in free spins are multiplied by the current floor value. The metre shown in the game rules sets the bonus like this:

• Floor 1–3: x2
• Floor 4–6: x3
• Floor 7–9: x4
• Floor 10–12: x5
• Floor 13–15: x6
• Floor 16: x7

When the game reaches floor 16, it also awards a top-floor bonus of 66.67x the bet. That gives the free spins round real weight. At the same time, the overall payout ceiling stays modest compared with many newer high-volatility slots.

Below is the pay table, which outlines the symbol values and gives added context for Steam Tower’s max win potential.

With the symbols covered, here is how the slot plays.

Gameplay

The Steam Tower game has a 5×3 layout with 15 fixed paylines. Wins pay from left to right, so your strategy is based on choosing a total stake, not changing the lines.

You can try bets from £0.15 to £150 per spin. There is also autoplay, while spin, bet, and paytable controls are placed at the bottom of the screen.

The slot has 97.04% RTP and medium volatility. Before you play it for real money, check the RTP version at the casino.

I found the controls quick to respond and easy to follow. I would suggest this slot for low- to mid-stake play rather than very aggressive betting.

Here are our expert direct notes from checking the game:

Steam Tower felt calm and easy to follow, though the base game was fairly quiet. I did not trigger the bonus, but the game rules show that stacked wilds award 10 free spins, while extra wilds add 2 more spins and move the feature up the tower. That rising multiplier is the main reason to play it.
