Nitropolis

Nitropolis is a 6-reel, 4-row slot from ELK Studios set in a post-apocalyptic world ruled by four clans competing for Nitro. The game uses Nitro Reels, which can expand symbol coverage and create up to 85,155,840 ways to win. It has a medium-high volatility profile and a listed RTP of 96.1%.

Key features include respins, random Nitro Reel upgrades, and a free spins bonus game triggered by 3 or more bonus symbols. During the bonus round, a symbol is randomly selected to pay as a scatter, while all Nitro Reels become sticky for the remaining spins. The bonus can retrigger, and a bonus buy option is available for players who want to access the feature more directly.

This demo version is available to play for free and can be used to practice before playing for real money. It gives players a chance to see how the Nitro Reels, sticky symbols, and bonus game mechanics work in the slot before staking funds.
