Nitropolis RTP and Volatility

The slot features medium to high volatility and 96.1% RTP.
It will most likely take you some time to get used to the strange behavior of this slot as it has high volatility. Here prize combinations of premium symbols and bonus features are not triggered often, but they can bring massive payouts! The theoretical return is on your side as it is 96.1% which is even slightly above the industry average.



All actions take place in a dystopian parallel reality, where animal clans began to rule the world. Here you will see Rouge Rats, Gritty Kitties, Dirty Dawgs, and Pug Thugs competing for dominance on the streets and the game is soaked in a bright green liquid that feeds their vehicles. Visually, this game really impressed us, and you will get a lot of funny comments from various characters during the gameplay. The soundtrack seems a bit mixed, but during the bonus round, there is a punk influence.

Let's now check what's going on in the paytable! Warrior Doberman, kung fu sphinx, mechanic pug, and bandit rat are premium symbols. Barrels labeled Rouge Rats, Gritty Kitties, Dirty Dawgs, and Pug Thugs are medium symbols. Low-paying icons are playing card suits in the form of a liquid spilled on iron.

About ELK Studios

Bonus Rounds & Free Spins


Nitro Reels

The so-called Nitro Reels can appear on any spin and anywhere on the playing field. When they land, 1 symbol will take up 2 vertical positions and contain 4, 6, 8, 10, or 12 symbols, which means there will be really many symbols in the prize combinations. This is a bit like a feature that you can find in Punk Rocker slot.


Whenever you create a winning combo during base game or free spins you will be granted a respin. If Nitro Reels are active on the playing field during the received respin (read above), there is a chance that the number of symbols on the reel will be increased for more massive wins. If the respin does not create 1 more win, you can get a second chance and your Nitro Reels will respin.

Free Spins

As soon as 3+ Bonus symbols land on the playing field, the slot will trigger the free spins feature and you can win from 10 to 25 free spins. Before the free spins feature starts, 1 symbol is selected and then the selected symbol will award Scatter payouts, which increases the total win during the feature.

When you are in the free spins feature, Nitro Reels become sticky. This will cause the symbols inside the Nitro Reels to spin, but you will always have the same number of additional symbols on that reel, which is really good. With Sticky Nitro Reels, you'll see all sorts of upgrades, respins, and second chances and it's a little crazy, but it's nice to see so much activity at once!

Nitropolis Demo Play

Players who don't want to spend money on bets or want to try Nitropolis for free before playing for real money can use its demo mode! The free mode of this game from ELK Studios is available right on this page. You only need to click on the "Play Demo" button to be able to bet with "fun" coins and not real money.

Max Win

Win up to 10,000x the bet.
In this slot machine you can win up to 10,000x the bet, and, well… we would say that this is a huge max win potential considering the max bet is €100 but it doesn't look so "wow" as the game provides up to 85,155,840 ways to win. With such a crazy number of ways to win, the max win potential could be much higher. We're not complaining, it's just a fact.

Overall Rating


The Megaways engine has become a big hit, we can't argue with that, and it's only natural that other providers will try to create alternative versions of it. Nitro Reels is a nice innovative mechanic from ELK Studios but it can seem a bit confusing at first especially when combined with the respins and second chances that haunt you after every combo but pretty soon you get the gist of it. In practice, this slot works like a crazy Megaways game as there are an incredible number of potential ways to win. We think that this engine will not be popular as the gameplay seems a little odd compared to Megaways engine slots. The 10,000x the bet potential is solid enough, but not exceptional with so many ways to win possible.
