Nitropolis Review

Look and Feel

Nitropolis is an online slot game from ELK Studios, released in early November 2020. We have been increasingly pleased with the level of ELK Studios’ output of late, and at first glance this slots looks like it is going to be a superb addition to the nifty Swedes portfolio of excellent slots. Of course, it’s not the done thing to simply judge a slot on the way that it looks, so we’re going to undertake a much closer examination before we deliver any kind of verdict. On the surface though, we are liking what we are seeing!

You’ve probably worked it out, but in case you haven’t, ‘Nitropolis’ is a play on ‘Metropolis’ which has been a name used for any kind of sprawling urban landscape since the ground-breaking 1927 movie. There have been updated versions of that movie, and in particular the 2001 Anime version which we really recommend. Just so you know, ‘Metropolis’ kind of means ‘mother city’ in Greek, which is where the name truly originated.

No matter how much you search around this slot for a progressive jackpot you will not find one. The maximum amount you can win is 10,000 times your stake.

Play for Real Money

There are zero places in the UK where you will be able to take Nitropolis for a spin because of UKGC rules and regulations. There are a large number of places through where you can play Nitropolis for real cash, including Video Slots. This site has just about every slot you can think of, and many great deals and offers, so go check them out!


This game is all about gangs, run by rats, cats and dogs. The four gangs are the Dirty Dawgs, Rogue Rats, Pug Thugs and Gritty Kitty. This slot also on each spin has a random number of paylines having six reels and four rows as a minimum (4,096 paylines). The number of paylines can max out to a staggering 85,155,840 ways to win.

You start play on this game the normal way by selecting the size of your stake. This can be as little as £0.02 and as high as £100. ELK Studios are still (sadly, in our opinion) offering betting strategy options. As ever, we suggest you steer well clear of them. To earn payouts you need to land identical symbols on a payline from the left-hand reel onwards. Wins are paid in line with your bet size as indicated below:

Playing Card*

*all playing card values earn the same, but they must be the same symbol on a payline to win

A nuclear mushroom cloud acts as the wild symbol here. It substitutes for all other symbols aside from the scatter and bonus symbols, although it does substitute for the scatter symbol during free spins.

A ‘nitro reel’ is a reel that has a symbol multiplier randomly applied to it. For example a ‘nitro reel’ may count two identical symbols on top of each other as a dozen symbols. This multiplier can upgrade in value during a respin or free spins. Sometimes the ‘nitro reel’ will respin for free at random. All ‘nitro reels’ that appear during free spins will lock in place for the remainder of free spins.

All the symbols and ‘nitro reels’ that form any part of win will respin on an individual basis. You trigger respins as long as you qualify for them.

If you land three or more bonus symbols then you trigger the bonus game. During the bonus game one symbol is selected in turn to pay out as if it was a scatter symbol. 

Graphics and Sounds

We’ve already noted our enthusiasm for the graphical nature of the game. The cartoony aspect works really well although if we were in nit-picking mode we’d say we’d have preferred a little more in the way of animation. The ‘nitro reels’ concept could have made this slot ugly and confusing-looking, but the way ELK Studios have handled it could not be better.

The music used is a very odd arrangement of noises, beats and robotic voices. It fits in very well with the theme of the game and is eminently listenable to. The rest of the sounds employed are fairly standard, but do not detract from the gameplay at all. Top effort!


ELK Studios have produced many excellent new online slots in 2020 and we can certainly add Nitropolis to that list. The ‘nitro reels’ aspect is very similar to the overused ‘Megaways’ concept from Big Time Gaming, but it’s not quite identical. It certainly adds a new dimension to what otherwise could have been a slightly mundane slotting title. Such a shame about those ‘betting strategies’ though.

We genuinely suggest you pay a visit to Nitropolis at one of our many recommended online casinos.


Q. What other online slots have ELK Studios produced in 2020?

A. Other titles that ELK Studios have created in 2020 include Visitors, Diablo Reels, Dreamzone, Io and Black River Gold. All of these slots come with our recommendation.

Q. Why are you so against the ‘betting strategies’ on offer via ELK Studios games?

A. A ‘strategy’ is something you adopt to increase your chances of winning. You cannot adopt any strategy with an online slot to increase your chances of winning, which is why you should not use them.

Q. Any more online slots games we can expect from ELK Studios in 2020?

A. ELK Studios intend to release two more slots before the end of 2020, named Knockout Diamonds and Katmandu Gold.
