ELK Studios, a Stockholm-based slots developer, made an exciting announcement recently, which will especially appeal to the fans of one of their most popular slots. They’ll be launching the fourth Nitropolis slot on February 23^rd, and it will have the same 50,000x max payout and expanding ways that can generate a reel that will barely fit the screen. We gave this slot a good spin, and in this post, we’ll cover all the new features of this iconic release.
