Nitropolis 2

Nitropolis 2 by ELK Studios is a six-reel, four-row slot with Nitro Reels, a Nitro Booster top reel and both-ways pay features. The game is set in a city-cleanup theme with Sergeant Nitro Wolf and includes medium-high volatility, a 95% RTP and a betting range from 0.20 to 100.

The main mechanics centre on Nitro Reels, which can cover two symbol positions and hold different payout symbol counts. Winning respins can extend when new combinations land, while the Nitro Booster may apply green effects to one column or gold effects across all Nitro Reels, including upgrades, guaranteed wilds, bonus symbols and respins.

Three or more bonus symbols trigger the free spins bonus game, where Nitro Reels lock in place for the remaining spins and the round can be retriggered. This demo version is available to play for free, allowing players to practice before playing for real money and to study the features before wagering.
