Steam Tower Demo Mode

Steam Tower by NetEnt was released in 2015 and still stands out thanks to its unique mechanic of climbing the tower floor by floor, with a dragon waiting at the top. The key feature is the free spins with a progressive multiplier up to x7 and the potential to reach the 16th level. To test the mechanics, see how the wilds and bonus work, and decide whether it’s worth climbing higher, you can try the demo version right here or in the Legalbet online slots catalogue.

Steam Tower: Design and Theme

🖼️ Graphics

This is steampunk without unnecessary polish: copper pipes, pressure gauges, rivets, and an industrial-style platform at the base of the tower. On the reels, you’ll find gear-themed card symbols and round medallions — the serpent’s eye, the hero in a top hat, the girl, the lookout tower. The interface is equally “mechanical”: dial indicators for floors and multipliers, and a green spin button shaped like a steam pedal. During free spins, the sense of “ascending” is reinforced by progress bars and floor changes — visually, it’s always clear where you are and which multiplier is active.

🎶 Sound

The background music feels like something lifted from modern Sherlock Holmes-style films — a hint of adventure mixed with restrained tension. It’s complemented by soft steam hisses, heavy mechanical clicks when spinning, and warm copper-like “ding” sounds when symbols land. During the bonus round, the tempo picks up, emphasising the importance of each spin. The soundtrack doesn’t overwhelm; instead, it gently guides the player, supporting the feeling of moving upward.

Special Symbols

  • Wild (Grappling Hook) — substitutes for all symbols and helps complete or improve combinations. In free spins, each wild adds +2 spins and moves the player up +1 floor.
  • Stacked Wild (the hero covering the full reel) — also acts as a wild and participates in combinations like a regular one. Its additional feature: if it covers an entire reel, it triggers 10 free spins and moves the player to Floor 1 of the tower.

Bonus Game

  • Free spins are triggered when a Stacked Wild fully covers a reel in the base game.
  • The round starts on Floor 1 with a x2 multiplier.
  • Each wild that lands during the bonus adds +2 free spins and moves the player one floor higher.
  • The higher the floor, the higher the multiplier: from x2 on the early levels up to x7 on Floor 16.
  • If you manage to reach the top floor, you receive an additional 1000 coins × bet level (approximately x66.67 of the total stake).
  • After the bonus round ends, the player returns to the base game and the multiplier resets.

RTP, Volatility, Maximum Win

The official RTP of Steam Tower is 97.04%. Volatility is listed as medium: wins occur fairly often in the base game (hit frequency about 33%), but the bonus triggers infrequently — roughly once every 100 spins. The maximum win in the bonus round is approximately x1,633 of the stake, while the base game max win reaches x2,000 of the stake.

Our Verdict

Steam Tower feels like classic old-school NetEnt: a simple base game with all the excitement packed into the free spins. Climbing the tower with an increasing multiplier is genuinely thrilling — sometimes you ascend floor by floor, and sometimes you stall early without even seeing x4. The slot is honest: no unnecessary layers, no jackpot, no tricks — just transparent mechanics and a rare steampunk atmosphere.

Who will enjoy it? Players who like a sense of progression and a clearly structured bonus round. Who may not? Those who prefer high-speed gameplay and features in every spin — waiting for the bonus here may feel too long.

If, after reaching the top of the tower, you fancy trying a Dracula-themed slot, check out Dracula Riches. And if you want to dive into total absurdity, go straight for Kenneth Must Die.
