How We Review Slot Games

Dirty Dawgs of Nitropolis is the third of five Nitropolis games to be released by ELK Studios in 2024. The story goes that each clan has withdrawn to their own territory to prepare for one last battle for overall control of the city which will play out in the climactic Nitropolis 5, set for release later in the year.

Dirty Dawgs follows the same frenetic pace of all other online slots in the series this time across 6 reels with 20 paylines to win on. Nitro Wild Reels bring mini wild stacks into play and Feature Boxes add re-spins, Nitro Wild expansions and instant win raffle prizes into play. The climax of the game is the free spins round with sticky Nitro Wild Reels. Top win is 25,000x and spins start at 20p per play.

Testing Notes: Here’s What Happened When We Played Dirty Dawgs of Nitropolis

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Boom Or Bust? Our Session By The Numbers

I played 250 spins on Dirty Dawgs of Nitropolis on ELK Studio’s test server prior to release to test the game. This is what happened.

  • Stake Size: €1
  • Start balance: €1,000
  • End balance: €850
  • Hit Rate: 19.6% (49 winning spins in 250)
  • Biggest Win: 18x
  • Free Spins Round: 0

This definitely had the feel of a high variance game, as expected. The hit rate was low at 19.6%, and I didn’t manage to trigger free spins once in 250 plays. Yet like all Nitropolis games, Dirty Dawgs felt busy throughout. There is always something happening on the reels, with regular Nitro Wild Reels appearing and plenty of feature boxes playing out too. Of course, when they don’t deliver that can be frustrating, but if you like busy games with a lot of action then you’ll like this one.

Dirty Dawgs of Nitropolis 18x win
An 18x win from 2 expanded Nitro Wild Reels

In the end the best win over 250 spins was an 18x, triggered when a feature box triggered two Nitro Wilds to expand on reels 1 and 2. That’s the kind of thing you are looking for in the base game – combinations of wilds and modifiers to help complete a few good paylines.

What We Liked

  • Nitro Wild Reels randomly expand to full reel height
  • Raffle in Nitro Features can drop instant wins up to 25,000x
  • Classic Nitropolis production style with pacey soundtrack
  • Nitro Wild Reels are sticky in free spins

What We Didn't like

  • Maximum RTP is 94%
  • Very similar style to other Nitropolis games

What Our Reviewer Says ...

"Another exciting journey to Nitropolis with typically busy and chaotic gameplay, this time with tons of mini stacks of wilds, re-spins and instant wins!"

Overall Score: 8.2

Theme & Design

Our Score 8

Another Frenetic Journey Into The Dystopian World of Nitropolis

You certainly know what you are getting with a Nitropolis slot –dystopian narrative, chaotic scenes, gritty urban landscapes with industrial steel, pipes and fluorescent Nitro fuel containers. All to the beat of a turbo-charged electro soundtrack. And all that is present and correct here. The dirty dawgs are a tooled-up bunch, wielding weaponry and ready to do battle, and the action is as frenetic as ever.

RTP and Variance

Our Score 8

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Dirty Dawgs of Nitropolis runs at the standard ELK Studios game RTP of 94%. Yes, it’s lower than the optimum RTP found on most online slots, but it’s a fixed rate. There are no other options for operators to choose from so you know what you’re getting wherever you play.

And there is no argument over the variance here either which is as high as you find on any of the other Nitropolis slots.  So, expect a volatile gaming experience, with the chance that the game might just go ‘pop’ at any time.

Maximum Win

Our Score 9

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

The max win is set to 25,000x, again in line with the other Nitropolis releases from 2024. That’s a nice chunky potential to aim for. You can find more games like this in our list of the highest max win slots.

Symbols and Paytable

Our Score 8

Dirty Dawgs has 6 reels and 4 rows but this is no 4,096 payline slot. Instead it runs with just 20 paylines, with wins triggered by landing 3 or more identical symbols across any line from left to right, starting at the left most reel.

Dirty Dawgs of Nitropolis Paytable
The paytable with 25x for 6 top paying premiums

There are 10 pay symbols to win with. The low value ones are the cards, 10 through to Ace. These are valued at from 0.1x for 3 10s up to 3.5x for 6 Aces. The premiums are the dog food bowls, beer mug, pistol, studded collar and deputy dawgs badge. These are valued at from 0.25x for 3 foods bowls up to 25x for 6 badges.

There are also wild symbols, represented by any dawg with the word ‘wild’ written across them. These substitute for any pay symbol to complete a payline and are valued at the same level as the premium badge symbol – 1.25x, 2.5x, 5x or 25x for 3, 4, 5 or 6 on a line.

Features and Gameplay

Our Score 8

The features in Dirty Dawgs are all variations on themes we have seen in other Nitropolis games to date, including Nitro Wilds, various Nitro modifiers and free spins. Here is how they work.

Mini Stacks of Nitro Wild Reels  

If you’ve played Nitropolis games before you will be familiar with the Nitro Reels concept. There are mini stacks of symbols that cover between 2 and 4 rows within a reel. In other games they may be any pay symbol. In this instance they are Wilds.

Only one can land per reel.

You don’t see the number of wild symbols within the Nitro Wild Reel but rather a number displayed at the top of the Nitro Wild Reel tells you how many wilds are contained within it. This number can randomly increase at any time.  And … the size of the Nitro Wild Reel can expand too to 1×3 or 1×4 (full reel) at any time.

Nitro Feature Boxes Contain Special Modifiers

There are five special Nitro Feature Boxes in the game too. These are represented by boxes with glowing contents with the name of a modifier written on the outside. They are:

Respins – the reels re-spins and any Nitro Wild Reels, Feature Boxes and Scatters stick

Wilds – the box simply converts into a wild

Expand – causes a Nitro Wild Reel to expand to 1×4

Raffle – all Nitro Wild Reels become unique spinning reels that will stop to display either a blank or a coin. Coin values are instant pay prizes and can include the max win of 25,000x

Dirty Wilds Add Nitro Wild Reels 

The Dirty Wilds feature can trigger at any time during a spin. When it does, a random number of fully expanded Nitro Wild Reels will be added to the reels before the spin ends.

Free Spins With Nitro Wild Reels

The main even as ever is the free spins round. To trigger this you need to land three or more BONUS symbols anywhere on the reels on a single spin.

The more BONUS symbols you land, the better the configuration is, as follows:

  • 3 BONUS symbols – 5 free spins
  • 4 BONUS symbols – 5 free spins with one Nitro Wild Reel
  • 5 BONUS symbols – 5 free spins with two Nitro Wild Reels
  • 6 BONUS symbols – 5 free spins with three Nitro Wild Reels

There is one enhancement in the free spins round – all Nitro Wild Reels are now sticky. And, if you can achieve SIX Nitro Wild Reels across the game area then you extend the round by 5 spins. This can only happen once.

The Final Verdict

The Nitropolis formula works well and ELK have delivered once again with Dirty Dawgs. After a total curve ball with the Rogue Rats desert driving game it’s nice to be back in the tried and tested environment of a 6-reel slot. What makes these games work is the busy gameplay that never lets up even when it’s not really delivering wins for you. Lots of wilds and modifiers appear, most of which you will find to be near misses rather than actual wins, but that is part of the fun and above all Dirty Dawgs just continues to be entertaining throughout.

Useful Tips When Playing Dirty Dawgs of Nitropolis

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Look For Bonus Symbols To Trigger Free Spins

The best stuff is going to happen in the bonus round so look for those BONUS symbols that trigger free spins. You’ll need at least 3, then you get 5 spins with sticky Nitro Wild Reels!!

2. Set A Low Stake

Nitropolis games are notoriously volatile so exercise good bankroll management and set a low stake level relative to your balance to ensure you don’t burn through your funds too quickly.

3. Feature Boxes Have Powerful Potential

Outside of the Nitro Wild Reels, the modifiers in the feature boxes have some of the most powerful potential in the game. Look out for raffle modifiers that can land you coins with instant win values of up to 25,000x!!
