Nitropolis Slot Review
Nitropolis Slot is one of the more exciting and best slot machines to play from Elk Studios, and for good reason. Released in November 2020, this game was pegged as Elk Studios’ biggest release of that year. The post-apocalyptic dystopian setting features four species gangs—the Rogue Rats, Pug Thugs, Gritty Kitties, and Dirty Dawgs—each with bold, distinctive character designs. We were immediately struck by the intense and interesting theme with its great overall design. The soundtrack is upbeat electronica with dynamic audio cues that perfectly complement the dystopian atmosphere.
What caught our attention most is that Nitropolis brings something genuinely new to the slot world. With an unprecedented 85,155,840 ways to win and innovative game mechanics we hadn’t seen before, this is a game that separates itself from the typical slot release. The 96.10% RTP makes it a high-RTP offering compared to many competitors in the market, and the 10,000x maximum win potential gives players genuine headline-level payouts when conditions align.
Base Game and Features
Nitropolis operates on a 6-reel, 4-row configuration with scatter pays providing those incredible 85,155,840 ways to win. This is an unprecedented setup that gives the game its distinctive character compared to standard five-reel designs.
The base game features several interconnected mechanics that create a dynamic, constantly evolving experience. Nitro Reels are special reel symbols that cover 2 symbol spaces and can hold 4, 6, 8, 10, or 12 symbols—they can randomly upgrade during respins or free spins, adding an element of unpredictability to each spin. The game uses a sophisticated system where winning symbols trigger Winning Respins, allowing all winning symbols and Nitro Reels to respin individually. As long as winning combinations keep forming, the respins continue, creating potential for multiple consecutive payouts from a single spin.
There’s never a dull moment in Nitropolis; the game maintains constant engagement through these numerous features. The Second Chance Respin mechanic provides additional thrill—when no additional wins are present, Nitro Reels in view may randomly respin at spin end, giving you another shot at landing winning combinations. Layer on top of that the Avalanche mechanism, where winning symbols are removed from the reels to enable multiple consecutive payouts through a cascade system, and you have an incredibly feature-rich base game.
Betting is flexible with a minimum stake of £0.20 and maximum of £100, and Elk Studios has included smart Betting Strategy mechanics with four options: the Optimizer (bets a percentage of balance), Leveller (raises after 5 consecutive losses), Booster (raises on loss), and Jumper (raises on win). These tools let you tailor your betting approach to your preferred play style.
Bonus Features
The free spins bonus is where Nitropolis truly shines. Landing 3 or more Bonus Symbols triggers the feature, and the number of symbols determines your spins: 3 symbols = 10 spins, 4 = 15 spins, 5 = 20 spins, and 6 = 25 spins maximum. During the free spins round, all Nitro Reels lock in place and remain sticky for the entire duration, significantly increasing your win potential. The ability to re-trigger the feature in-game means you can extend your bonus run and accumulate impressive wins.
A standout mechanic is the Scatter Pay feature, which works uniquely during free spins. A random symbol is selected as the Scatter Pay symbol at bonus entry, and three or more of this symbol across different reels generates a win. When the feature is re-triggered, an additional symbol is selected, adding strategic depth to the free spins experience.
For players who want to skip the wait, Elk Studios has incorporated a Bonus Buy feature that allows you to purchase entry directly into the free spins bonus. This provides flexibility for different player preferences—whether you’re after the building excitement of natural triggers or the immediate thrill of jumping straight into the feature.
Volatility and Gameplay Style
Nitropolis features high volatility, which means wins are less frequent but can deliver significantly larger payouts when they do land, creating dramatic gameplay swings. This positioning makes the game ideal for players seeking big wins and willing to accept the variance that comes with it. The gameplay is action-packed with many features, but the in-game information does an excellent job of helping you understand the mechanics. After a few spins, everything starts to make intuitive sense.
One observation from the community: bonus triggers can feel challenging without feature buy assistance, but at just 3x bet cost, the Bonus Hunt feature increases trigger chances by more than 4 times, providing an accessible path for players who want more frequent bonus access. There is undeniable style here with a bold, disobedient aesthetic and plenty happening in the base game to keep things genuinely engaging.
Mobile Experience
Nitropolis offers fully responsive mobile play across iOS and Android devices without requiring any downloads. The mobile experience is seamless and responsive, maintaining full functionality and visual quality whether you’re playing on smartphone or tablet. This means you can enjoy the post-apocalyptic action anytime, anywhere.
Quick Verdict

With 96.10% RTP and 10,000x win potential, the game delivers solid value for high-RTP seekers. High volatility means wins are less frequent but can be substantially larger, creating the kind of dramatic swings that appeal to players looking for genuine excitement. The game does require some patience to trigger bonuses naturally, and bonus buys are relatively expensive, but these are minor considerations in an otherwise excellent package. If you enjoy a slot that is super fun and dynamic with plenty of action, Nitropolis is absolutely worth trying for its engaging mechanics and potential for sustained play.
