• J to A card royals in splattered paint and some gang patches are the low-paying symbols.
• Pug Thug, Rogue Rats, Gritty Kitty, and Dirty Dawgs clan badges are the high-paying symbols.
• The wild is an atomic explosion that stands in for any symbol except the scatter.
• The scatter is a red and chrome engine that triggers free spins.

If I called the gameplay experience ‘exciting’ or ‘frantic’ it would be a gross understatement as the unique combination of bonus features and a game-changing mechanic delivers a breakneck-paced experience, full of surprises.

Winning Respins

After a winning spin, the symbol positions involved will respin, potentially setting off a chain of wins as new winning combinations appear.

Nitro Reels

This proprietary mechanic is central to the thrills that this title delivers. Special frame symbols appear randomly, covering 2 reel positions. This feature effectively boosts your available paylines by filling each frames reel position with up to 12 symbols. This means that the starting 4096 paylines could increase to as much as an astonishing 85, 155 840. This increases your overall winning chances and potential and I found that this feature triggered fairly often, although whether its appearance results in a huge win is up to your luck. This feature also includes a random Upgrade modifier where the number of symbols on a position is increased. There is also a Second Chance sub-feature that causes the Nitro Reels to spin again and generate a different symbol.

Free Spins

The bonus round gets going when you land 3 to 6 scatters on the reels, awarding you 10 to 25 free spins. A symbol will be randomly chosen to be the Scatter Paying Symbol that can pay from any position on the reels for the duration of the feature. The cherry on the top is that all Nitro reels will become sticky for as long as the feature lasts, presenting you with some amazing winning opportunities.

Nitropolis is an internally polarising experience, but its compelling allure is undeniable. I was thrilled with the combination of a cartoon style theme with a dystopian setting and while the soundtrack matches the game’s chaotic appearance, you might end up turning it off after a few spins. I was truly blown away by just how many features ELK Studios managed to pack into this title. The Nitro Reels mechanic is the crazy glue that intuitively blends the features with the free spins being particularly exciting, especially when sticky nitro reels push your potential through the roof.

While I was fully invested in the experience, players with minimalistic sensibilities may feel that the combinations of bright visuals and high-energy audio is an assault on their senses, although the game’s top potential prize of $1 million may be enough to compel some out of their comfort zones.
