Steam Tower is a NetEnt slot released on 23 February 2015. The official NetEnt page confirms a steampunk 5x3 slot, with 15 lines, an RTP of 97.04%, a hit frequency of 33.00% and a max payout of 1,000x.
The game features a Victorian tower ascent: the narrative objective is to save the princess from the dragon, with Free Spins where the multiplier increases as you go up the floors. It is an older model compared to highly-loaded modern slots, but it features clear official values and a clean bonus mechanic.
From the player's perspective, the central focus remains the Free Spins feature: it turns the ascent into a multiplier progression, without stacking too many secondary modules.
What NetEnt confirms
The official page provides the main metrics and functional blocks. The data embedded in the page also confirms HTML5, desktop/mobile compatibility, a Lines pay type, and a numerical volatility score of 5.7/10. Since this score is numerical rather than a player-facing label like Low/Medium/High, it is retained with this nuance.

Free Spins, floors and multiplier
The official feature block explains that, during Free Spins, line wins are multiplied by the current multiplier. This multiplier is displayed in a meter and updates before each spin according to the floor reached by the player.
The top of the tower corresponds to floor 16. When reached, NetEnt indicates a bonus coin win of 1,000 coins multiplied by the bet level, with a x7 multiplier. After the Free Spins end, the game returns to the ground and the multiplier is reset to zero.
Stacked Wilds and risk reading
Steam Tower uses Stacked Wilds, which can make certain spins easier to read without turning the game into a modern slot with dozens of features. The point of vigilance is rather the pacing: the RTP is high for a NetEnt game, but the bonus progression depends on the ascent and the multiplier.
The official page does not mention a Feature Buy option active for this game; the embedded data even indicates that this option is not active. The best practice remains to check the help screen of the casino version, especially if the operator uses a local variant.
Our quick opinion
Steam Tower will mostly appeal to players looking for a classic NetEnt game, with clean official figures and an easy-to-understand bonus feature. The max payout of 1,000x is more modest than that of many recent slots, but the official RTP of 97.04% and the steampunk identity still give a genuine reason to try it in demo mode.
To stay within the NetEnt catalogue, compare it with Taco Fury XXXtreme, Ticket To Wild, Superstars or Street Fighter II: The World Warrior Slot. The slot machine hub, the best online casinos and the online casinos France page then help to place the game in a broader selection.
