PLAY A Closer Look at the Steam Tower Slot Game
Gears churn and pipes bellow as a new era of industry dawns in the Steam Tower slot game. Amidst these advancements, a hero rises to take on an ancient dragon, much like the knights of old. To aid him, we have stacked wilds and free spins with multipliers. Ready to defeat the infernal dragon? Here’s everything you need to know to start your quest.
The game is set on a 5x3 grid with 15 paylines and a medium volatility setting. Despite the medium variance, landing winning combinations took anywhere from three to seven spins, and the lack of wilds seemed to be the culprit. When I did land winning symbol combos, the payouts were generally low, ranging from 0.20x to 1.66x my bet, which was far too low to maintain a stable bankroll.
That said, wilds and stacked wilds are crucial to the game. Since there’s no dedicated scatter symbol, landing a stacked wild that completely covers a single reel unlocks the free spins feature. You start with 10 free spins, and each win during the round advances you one floor on an elevator. Every wild landed adds two extra spins and a bump to your multiplier meter which starts at 2x and is active throughout the round.
Thanks to frequent wilds, I was able to play a few extra spins and reach an epic 8x multiplier more than once. I made between 70x to 90x returns from this feature, which was definitely worth the wait. These progressive free spins played a big role in making my playthrough of the Steam Tower slot successful. If you’re playing in free spins casinos, triggering the feature can lead to some handy payouts!
Steam Tower RTP and Volatility
The Steam Tower slot game comes with an RTP percentage of 97.04% which means on average it should have higher returns than the average slot game following industry standards with an RTP of 96%. The game also strikes a good balance between the amount won and how long it takes to trigger said win with a medium volatility setting.
Playing Steam Tower with Free Spins Bonuses
If triggering the features inside the Steam Tower slot game is your top priority, playing in a no deposit free spins casino can be a great way to not risk your funds during the base game and enjoy the profits from the free spins feature in-game.
Fortunately, I noticed that 15 to 125 free spins were easily available for the Steam Tower slot game. The only issue I had with the casinos offering these bonuses was the wagering requirements which were quite high between 45 to 50 times your bonus amount.
Should You Play the Steam Tower Slot Game by NetEnt?
NetEnt’s Steam Tower slot is a roller coaster ride through and through. On one hand, it offers a solid progressive in-game bonus with rising multipliers, and many online casinos are currently offering bonuses for it.
However, the main game can feel like a slog, and the high wagering requirements can quickly turn that slog into a tedious challenge. If you're planning to take on the slot with a free spins bonus, I’d recommend choosing a casino where your favorite games are offered and where you plan on playing more. This way, you can fulfill your wagering requirements and withdraw your winnings quickly.
