How the Game Plays

Nitropolis 3 moves the infamous animal gangs—the Dirty Dawgs, Gritty Kitties, Pug Thugs, and Rogue Rats—from their dystopian city to a toxic, tropical beach. This slot begins on a 6x4 grid with 4,096 ways to win. Utilizing an avalanche mechanic, every winning combination removes successful symbols to allow new ones to drop in, while simultaneously adding an extra row to the grid. This expansion can continue until the grid reaches a height of eight rows, drastically increasing the number of potential winning paths.

Free Spins Explained

The bonus round is triggered by landing three or more blimp scatter symbols, awarding between 8 and 20 free spins. A key advantage in this mode is the Safety Level mechanic; unlike the base game, the grid height does not reset between spins, so every row added remains for the rest of the session. Furthermore, any Nitro Reels that land during the round become sticky, remaining in place to provide massive win potential on every subsequent spin.

Nitro Reels and Super Bonus Explained

Elk Studios includes its signature Nitro Reels, which occupy two symbol spaces but can contain up to 12 individual payout symbols. "Big" Nitro Reels are even more powerful, covering six positions with 2x2 symbols. For those seeking the ultimate challenge, the Super Bonus is triggered when a Super Bonus symbol is present during the activation. This mode is played on a permanent 8-row grid where wins pay "Both Ways," calculating combinations from both left-to-right and right-to-left.
