Steam Tower is the name of this Net Entertainment slot machine. This seems to be quite a popular machine among the twitch viewers. I think it’s a really great game, and it has a free spin feature that can be triggered really rapidly. A cool thing about Steam Tower is the way the free spins are triggered, one stacked wild symbol covering a whole reel is all you need. There is also a very interesting free spin feature on this game, quite different from any other free spin rounds I can think of. It features a win multiplier that increase based on the number of wild symbols that appear during the spins. There is also a top floor bonus, that will be paid out if you reach the maximal x7 win multiplier. The maximal potential win can only be won during the base game, and it's won by filling each of the 5 reels with a staked wild symbol. This will pay a win of 2.000x the stake, and also trigger the free spins. The RTP for this game is 97.00%

Game features

Steam Tower has stacked wild symbols on all the reels during the base game, and single wild symbols on all reels during the free spins. These symbols substitute for all other symbols, and the stacked symbols might even trigger the free spins. The base game has a normal slot gameplay, while the free spin feature is a bit more interesting. During it, a win multiplier might multiply wins by up to x7. There is also a top roof cash prize awarded if you reach the highest multiplier.

Free spins: The free spins are triggered when one or more stacked wild symbols appear on and cover at least one entire reel. This will activate 10 free spins regardless of the amount of triggering wild symbols. The stacked wild symbols will be replaced with single wild symbols during the feature. During the free spins a dashboard with different values will show below the reels. The first indicator in the dashboard will show which floor you’re at, the next one will show the remaining spins, while the last one will show the current win multiplier. You will always start on floor 1, with 10 free spins and a x2 multiplier.

For each spin where one or more wild symbols appear, the floor indicator will increase by +1, and +2 more free spins will be rewarded. The multipliers will increase on floor 4, 7, 10, 13 and 16, which multiply the wins with x3, x4, x5, x6 and x7. If the x7 multiplier is reached, a top floor bonus of 66.6x the stake is awarded. All remaining and possible new spins will be finished with the x7 multiplier. The free spin feature ends when no more spins are available, and there is no way to re-trigger the whole feature.
