Wilds
The hero’s green grappling hook is the game’s wild symbol, which substitutes for every other symbol. It also plays a key role during the free spins!
Stacked Wilds
As the hero’s grappling hook is the wild symbol, it seems only right that it is he himself who acts as the stacked wild symbol. If this symbols covers a one or more whole reels then you can expect some good prizes and 10 free spins.
Free Spins
The stacked wilds trigger Free Spins. Once this occurs you are placed on Floor 1, with the unenviable task of reaching Floor 16.
You climb these floors by getting a wild symbol on the reels, these add up and move you up a level as well as 2 free spins. The higher you get the bigger the multiplier and you’ll even get a bonus reward for reaching the top level.
Our verdict
Whilst not the most visually appealing Steam Tower differentiates itself from other slots by giving you a distinct challenge to achieve whilst playing. This genuinely does make the game more fun and exciting as you climb the floors, and a good rate of return makes this a slot well worth playing.
