The theme of Nitropolis 3 is based on a pack of Nitro-animals in a post-apocalyptic world. The game design depicts the evil Sergeant Nitro Wolf as mighty, with all other animals running away from him. All these events take place on the beach, with ELK Studios drawing inspiration from the Yakuza gangsters in Takeshi Kitano’s 1993 movie Sonatine. As the name suggests, this is not the first game in the series and follows on from Nitropolis and Nitropolis 2. This latest version is an upgrade with superior characteristics such as the 50,000x max win potential and the Avalanche mechanic.

Players can win a game round in Nitropolis 3 by matching between three and six symbols on adjacent reels. The animal characters represent premium symbols, and they are worth 2x to 5x your bet if you match six of them on the reels. Wild symbols substitute other regular symbols to boost your winning chances.

Nitropolis 3 features up to four additional rows as a characteristic of the Avalanche mechanic. Wilds and other main symbols appear in the 4×4 size. Big Nitro reels also host 2×2 symbols. The super version and regular bonus rounds trigger organically in this slot, unlike other releases by ELK Studios.

The Avalanche mechanic works by removing symbols that have taken part in a winning round to create space for more symbols. More winnings trigger more Avalanche rounds as new rows are added up to a maximum of eight.

There is a demo version for new players to learn the game rules before placing real-money stakes. Nitropolis 3 is a heavily technical slot because of the dense 6×4 matrix and the Avalanche feature. The symbol sizes also vary, so you need time to learn their functionality. You may also enjoy free gaming without the worry of losing any money despite having the skills to play the slot.
