Nitropolis 3 Slot

Nitropolis 3 is an ELK Studios slot with 6 reels, 4 rows and 4,096 ways to win. It has a 95% RTP, high volatility, a 19.2% hit frequency, bets from 0.20 to 50 and a maximum win of 50,000x. Cascades, expanding reels, Nitro Reels, Scatters and Win Both Ways modifiers shape the game.

Theme and design

The slot uses a post-apocalyptic animal world with cats, dogs, mice, beach details and green-grey scenery. The screen can expand vertically, so the grid is meant to change as the round develops.

Nitro Reel markers and Zeppelin Scatters are the symbols to watch because they connect to the bonus structure.

Gameplay and ways

Wins use 4,096 ways on the starting 6x4 grid. Cascading wins remove symbols and allow new ones to fall into place.

The grid can expand up to 6x8, creating more symbol space and more ways for later cascades.

Symbols and payouts

Regular symbols use the animal and post-apocalyptic theme. Wilds can substitute for regular paying symbols.

Zeppelin Scatters trigger the bonus. Nitro Reels affect reel expansion and become especially important in Free Spins.

Bonus features

Three, four, five or six Zeppelin Scatters award 8, 12, 16 or 20 Free Spins. Nitro Reels become sticky during the feature and can stack on the same reel.

Safety Level progress saves the expanded grid between Free Spins. A Super version can start when a Super Bonus symbol is part of the trigger, opening the feature with the grid fully expanded and Win Both Ways active.

RTP, volatility and max win

The RTP is 95%. Volatility is high, hit frequency is 19.2%, and the maximum win is 50,000x. Bets run from 0.20 to 50.
