Dirty Dawgs of Nitropolis Special Features

In this section of the review, we will be shining a light on the special features available to us. These include; Nitro Wild Reels, Nitro Feature Box, and Dirty Wilds.

Nitro Wild Reels

Nitro Wild Reels will cover 2-4 vertical positions and contain a stack of Wild symbols. The level indicator on top of the Nitro Wild Reel will reveal how many Wilds are in the stack.

Nitro Wilds can be randomly upgraded to a higher level, increasing the height of the contained Wild stack, from 1×2 to 1×3, up to a max of 1×4. A fully expanded Nitro Wild Reel will cover the entire reel it is on.

Nitro Feature Box

The Nitro Feature Box triggers a random feature upon landing. It may also trigger additional features within a game spin. The Nitro Feature Box can deliver Respins, Wilds, Nitro Expand, and Nitro Raffle.

  • Respin – Awards a respin where Nitro Wild reels, Nitro Feature boxes, and Scatters remain sticky on the reels.
  • Wild – Converts the Nitro Feature Box into a regular Wild symbol.
  • Nitro Expand – Expands the size of a Nitro Wild Reel.
  • Nitro Raffle – Transforms all Nitro Wild Reels in view into smaller 1×1 spinning Coin Reels. Nitro Wild levels are temporarily deactivated during this feature. All landed Coins will award their values times your current bet level. Only 1 Max Win Coin can land during this feature.

Dirty Wilds

The Dirty Wilds feature can trigger randomly in the base game. Once active, it will land a random number of fully expanded Nitro Wild Reels onto the reel set before the remaining reels stop spinning.


Those outside the UK will benefit from ELK Studios’ X-iter feature, where 5 Bonus Buy options are available.

  • Bonus Hunt – More than triples your chance of triggering the Bonus round for 3x your bet.
  • Three Nitro Wild Reels – One spin with 3 guaranteed Nitro Wild Reels and where 3 or more Bonus symbols will trigger the Super Bonus round for 25x your bet.
  • Dirty Wilds – One spin with a guaranteed Dirty Wild trigger for 100x your bet.
  • Bonus – 100x your bet.
  • Super Bonus – Triggers the Super Bonus round with 3 persistent Nitro Wild Reels for 500x your bet.

Online Slots UK are devoid of such options, but all of the aforementioned features are still available to players through regular gameplay.

Dirty Dawgs of Nitropolis Bonus Rounds & Free Spins

Dirty Dawgs of Nitropolis features 2 Bonus rounds, one of which is a Super Bonus. Landing 3 Scatters in the base game triggers the Free Spins round, however, landing more than 3 Scatters will award a boosted Bonus round with up to 3 sticky Nitro Wild Reels. Alternatively, landing 6 Scatters will trigger the Super Bonus round.

The round begins after all Respins and Nitro Raffle features are complete. No Nitro Wild Reels will carry over to the Bonus round. Landing 6 Nitro Wild Reels during this time will award an additional +5 Free Spins.

Pros & Cons of Dirty Dawgs of Nitropolis

Below, we’ve compiled a short list of Pros and Cons that we feel are important to consider when choosing to play Dirty Dawgs of Nitropolis.


  • ELK Studios put to use tried and tested mechanics once again, but more uniquely to fit the new game.
  • 2 Free Spins modes, one of which is a Super Free Spins round. This can be triggered manually during regular gameplay. Players outside the realm of Bonus Buys will also benefit from this.
  • Impressive max win capabilities of up to 25,000x.


  • Bet limits are restricted, and there are no in-between options for many of the bet levels.
  • Low RTP of 94.00%, although this is down to personal preference.


Dirty Dawgs of Nitropolis continues the innovative legacy of the Nitropolis series with high energy and crazy gameplay that fans have come to expect from the franchise. Unlike Rogue Rats of Nitropolis, Dirty Dawgs of Nitropolis follows a more traditional route with features that feel more familiar.

Though recognisable. Dirty Dawgs of Nitropolis does have unique qualities, like the Nitro Feature Box and Dirty Wilds. These features bring a layer of unpredictability, and the Dirty Wilds feature increases the chance of significant wins with its ability to imbue the reels with fully expanded Nitro Wild Reels.

Despite its strengths, it does have qualities that might be seen as drawbacks to some, such as the lower-than-average RTP of 94.00%. It’s also highly volatile, so it’s suited for players who understand that wins may be infrequent, but potentially bigger when it does hit. The maximum win in this one is 25,000x the bet, making it equal to both Rogue Rats and Gritty Kitty.

Overall, it’s a worthy continuation of the series thus far. The Nitropolis series is beloved and recognisable, yet fresh, engaging, exciting and as capable as ever.
