Nitropolis

Nitropolis, developed by ELK Studios, throws players into a thematically rich post-apocalyptic world. Four distinct animal gangs – the Dirty Dawgs, Gritty Kitties, Pug Thugs, and Rogue Rats – struggle for dominance, vying for control of Nitro, a vital fuel source. The slot delivers a visually immersive atmosphere with a dystopian industrial setting. This game kicked off the popular Nitropolis series, which has since expanded to include titles like Nitropolis 2 and Nitropolis 3.

Gameplay Mechanics:

Nitropolis offers a dynamic playing experience with a 6-reel format. The number of rows can vary on each spin, ranging from 4 to 12, resulting in a potential maximum of 85,155,840 winning ways. Core gameplay revolves around forming winning combinations of three or more matching symbols on adjacent reels.

• Nitro Reels™: A central mechanic in Nitropolis. These special symbols can appear randomly on any reel. Expanding vertically, they hold 4, 6, 8, 10, or 12 of the same symbol, significantly increasing the probability of landing wins. Nitro Reels™ can also undergo random upgrades during respins or the free spins bonus, adding even more symbols and enhancing win potential.
• Winning Respins: Any winning combination triggers respins. All symbols involved in the win spin again for a chance to create new winning combinations. Respins continue until no new wins occur, maximizing potential payouts within a single spin sequence.
• Free Spins with Sticky Nitro Reels™: The primary bonus feature is activated by landing 3 or more scatter symbols (bonus symbols). Before the free spins begin, one symbol is chosen at random to become the scatter paying symbol. During free spins, this symbol can award scatter wins from any position on the reels. Crucially, Nitro Reels™ become sticky during free spins, locking in place for the entire bonus round. This creates exciting opportunities for extended winning streaks, as Nitro Reels™ won't be replaced with new symbols on subsequent spins.

Slot Symbols:

The slot features a well-defined symbol set. Low-paying symbols are represented by card suits, while medium-paying symbols depict various objects within the post-apocalyptic world. High-paying symbols showcase the distinct animal gang characters.

• Wild: Represented by a mushroom cloud symbol, the wild substitutes for all symbols except the scatter symbol during the base game. During free spins, the wild symbol also substitutes for the scatter symbol in scatter wins.
• Scatter: The scatter symbol, depicted as a bonus symbol, triggers the free spins bonus round.

The success of Nitropolis led to the creation of spin-off games focusing on individual animal gangs, such as Dirty Dawgs of Nitropolis and Gritty Kitty of Nitropolis.
