Steam Tower

Netent's Steam Tower is a video slot featuring 5 reels and 3 rows, offering 15 fixed paylines within an intricately designed steampunk environment. The narrative centers around a Victorian-era engineer on a mission to save a captive from a dragon residing at the top of an impressive tower, with visuals and sounds dominated by brass gears, cogs, and industrial machinery. A crucial element in the base game is the wild symbol, which can appear as a stacked wild when it fills an entire reel; landing a fully stacked wild triggers the Free Spins feature. Players start the Free Spins on the first floor of the tower with 10 free spins. Each additional wild landed during this round awards two extra spins and advances the player up one floor. As players climb the tower, which has a maximum of 16 floors, the win multiplier increases: a 2× multiplier is awarded for floors 1-3, 3× for floors 4-6, 4× for floors 7-9, 5× for floors 10-12, 6× for floors 13-15, and a 7× multiplier at the top floor. Reaching the top floor also grants a bonus coin win based on the player's bet level. After the Free Spins conclude, the game resets to the ground floor with its base settings. Outside of the Free Spins, stacked wilds primarily serve to activate the bonus, while wilds during the feature assist in advancing through the floors and increasing multipliers and spins. There is no option for a separate bonus buy feature in this game.
