If you don’t mind some chaos of a post-apocalyptic world that is ruled by four clans of animals, Nitropolis is the perfect place to be. This is one of many ELK Studios’ masterpieces that stay relevant for years. Released in 2020, it introduced Nitro Reels, which are one of the main contributors to the game’s success.  

Nitropolis is an all-round fantastic online slot. It is packed with thrilling features, offers top-level audio-visuals and an engaging story line. If you are looking for a slot that is super fun and dynamic, it’s worth trying this one. Just dive right into testing it as there are hardly any words to describe the beauty of this game.  

The max win is 10,000x but it feels like there could be a higher win cap as things can get pretty wild. But there’s definitely no lack of win ways as it’s possible to get over 85 millions of them.  

Following a massive success of the slot, the studio released several other Nitropolis installments with some of them offering up to 50,000x max payouts. The entire Nitropolis series has become popular with a wide range of players. But the original game stands out because it was the one that shocked the world.  


The studio combines a few features that never let you get bored. The core element, of course is Nitro Reels, that are key to landing millions of ways to win. Initially, the slot has a 6×4 layout, but each reel can then expand up to 24 symbols high.  

Nitropolis Nitro Reels

A Nitro Reel covers two symbol places but instead of two symbols, it generates 4 to 12 symbols within that space. One reel can accommodate two Nitro Reels, which gives you a 24-symbol wheel. And when you have many of them on a screen, the number of win ways can reach millions. Two boosters add extra layers of fun to this already thrilling feature: 

  • Second Chance Respin does just what it says. It spins Nitro Reels again to give players another chance of winning. It will start when no winning combinations land. 
  • Those respins mentioned above can also trigger the Upgrade to make Nitro Reels accommodate even more symbols. If there are 4 symbols, there can be 6 or more of them after the Upgrade. The feature can also be triggered during free spins.  

After any base game or bonus win, all symbols that are part of a winning sequence, spin again to possibly award more wins.  

Bonus Game 

Nitropolis Bonus Game

In the free spins, two things are added to spice up the gameplay. First is that all Nitro Reels remain on the screen for the remainder of the bonus round once they land. That’s when the chance of the max upgrade increases.  

Second thing that is exclusive to this round is Scatter Pays. One symbol is randomly selected to be a scatter, and as you probably know, scatters pay anywhere regardless of their position.  

The number of free spins depends on the number of bonus symbols landed. There should be at least three, which will get you 10FS. And the number goes up to 25FS for 6 bonus symbols. 


Nitropolis is a one-of-a-kind slot machine that at the time of release introduced players to something completely different from what they knew. It’s so easy to fall in love with a beautifully designed post-apocalyptic world and engaging gameplay. And music is absolutely fantastic, adding so much more flavor to this incredible game.
