How it Pays and Plays

You can start spinning the reels from as low as 0.2 coins right up to 100 coins, which will cover most players bankrolls. The volatility is marked as 8/10 whilst the RTP is a respectable 96.1%. You start with 4096 ways to win but you can get Nitro Reels which cover 2 symbol places and can provide an extra 4 to 12 rows of symbols on the reel they occupy. This is where the amount of ways to win multiplies all the way up to a potential 85,155,840 during the free spins bonus round where these Nitro Reels become “Locked” in place. The maximum win is 10,000x your stake.

Nitro Reels

On any given spin during the base game you can get a number of Nitro Reels which cover 2 rows and will hold 4 to 12 of the same symbol. These can also be Upgraded randomly which will give you a higher amount of symbols, up to a maximum of 12.


If there is a winning combination formed then the reels which formed the combination will respin and the Nitro reels can help your chances here of landing a decent sized win. The reels will keep respinning so long as you get winning spins, once you get a dead spin then the respins will generally stop but you can randomly get a respin anyway sometimes. 

Free Spins Bonus

You’ll need to land 3, 4, 5 or 6 Scatter Bonus symbols to get the free spins to trigger. This will give you 10, 15, 20 or 25 free spins respectively. Free Spins can also be retriggered during the bonus round. 

You will get one special symbol selected before the free spins start which acts as your Scatter Pays symbol providing you with additional winning chances.

The potential of the free spins bonus presents itself in the form of the “Locked” Nitro Reels. Once you land a Nitro Reel in during any spin in the bonus round it will be locked in for the whole of the bonus. Get a few of these locked in early on and you can see the ways to win meter in the top left sky rocket.  

Graphics and Sound

Nitropolis slot is really well designed and looks top notch graphically. It is set on the background of a cartoon style landscape representing a futuristic type of city view with building reaching up into the sky looking a little grim. 

The lower paying symbols are Ace, King, Queen and Jacks along with the badges of the 4 gangs. Premium symbols are the various animals from the gangs including, in descending order of value, The Dirty Dawgs (5x for 6 of a kind), The Gritty Kitties( 3.6x for 6 of a kind), The Pug Thugs (3.4x for 6 of a kind) and The Rouge Rats. (3x for 6 of a kind). 

The music is a futuristic/synthetic sounding cartoony upbeat number which goes perfectly with the game, it might not be to everyones taste though, in which case the mute button becomes somewhat handy.
