What do you get when the classic princess rescue concept receives an industrial era makeover? Why, NetEnt’s Steam Tower of course – a five-reel, 15 payline title with one incredible feature. Starring a steam punk-style adventurer armed with his trusty grappling hook, the aim of the game is to ascend a tower, defeat an evil dragon, rescue a princess and swing of into the sunset – but this can only be achieved by activating the slot’s free spins feature. During this mini-game, players will climb the various levels of the tower earning free spins and increasing prize multipliers, with a 1,000 coin bonus waiting for them at the top should they make it that far.
Steam Tower features a slightly unusual traditional-fairytale-meets-19th-century-adventure theme, with the classic “dragon captures princess” story now taking place in front of an industrial landscape. The game features impressive 3D graphics and initially starts at the base of the titular Steam Tower, with our dashing hero ascending this stone structure during the free spins feature. This slot’s main protagonist appears on the reels as a stacked wild symbol and also triggers the bonus whenever he covers an entire reel, with other unique icons to feature in the game including grappling hooks, the dragon’s eye, the princess and the top of the tower. An inspiring piece of background music plays throughout, with this getting increasingly more dramatic as players climb closer to the dragon.
As alluded to above, the main bonus feature in Steam Tower is a free spins game in which players will earn increasing multipliers and – ultimately – a big cash prize as they ascend the game’s titular structure. Activated whenever the stacked hero symbol completely covers one or more reels, players will initially receive 16 free spins, with every grappling hook symbol that appears awarding an extra two games and moving them up one level on the tower. For every three levels they ascend, a prize multiplier will increase by one, with a 1,000 coin award up for grabs should they make it to the 16th floor. Once here, free spins will continue as normal as long as more grappling hook symbols are collected, with all wins now being subject to the game’s top 7x prize multiplier.
With the 15 paylines in Steam Tower being fixed at all times, players must use the plus and minus arrows below the reels to control their bet level from 1-10 and their coin value from £0.01-£1.00. Combined, these two aspects make the slot playable from £0.15 to £150.00 per spin, while players can also launch up to 100 consecutive spins at their chosen bet level by using the autoplay button.
For a more modern twist on the classic “dashing prince rescues damsel in distress” story arc, look no further than NetEnt’s Steam Tower. Although the game only features one bonus round, it is a hugely immersive one that is capable of awarding huge payouts thanks to the presence of increasing prize multipliers and a 1,000 coin award that is multiplied by players’ current bet level.
