Nitropolis Review

The game plays out in a dystopian parallel reality where animal clans have taken over the show. The Dirty Dawgs, Gritty Kitties, Rouge Rats and Pug Thugs all fight over dominance of the green nitro that fuel their vehicles. Visually, the game is quite impressive, and you get plenty of fun action commentary from the crafty reel critters. The soundtrack is a bit of a mixed bag perhaps, but the punk influence shines through during the bonus round.

As you can expect with such an enormous number of winning ways, the symbols don’t pay all that much for smaller combos. The top dog pays only 5x for 6 on a payline, so you really need those Nitro Reels to get anywhere here. If you don’t know what you’re walking into, you might be a bit overwhelmed at first, but it doesn’t take that long to figure things out. It’s surely a good idea to read up on the features first though, and try the free demo version before you decide if this is for you.

Nitropolis Features

You will benefit from Winning Respins both in the base game and during the bonus round here. This means that all winning symbols spin again to give you another winning chance. The respins keep coming as long as you land new winning combos.

The defining feature is definitely ELK’s innovative and trademarked mechanic called Nitro Reels™. You can land these special symbols on all the reels, and they cover 2 positions framed by green pipes with a number on top. This number tells you how many matching symbols are packed into the Nitro Reel, and you will get 4, 6, 8, 10, or 12 symbols per instance.

Without any Nitro Reels on the screen, you play with the default 4,096 ways to win. However, the Nitro Reels mechanic can increase that number up to an eye-watering 85,155,840 winning ways.

This far exceeds all Megaways engine games out there, and it makes for tremendously dynamic gameplay.

The Nitro Reels have more tricks up their sleeve however, as they will sometimes upgrade their number of symbols (and thus the win ways) between winning respins and/or free spins. You can also get a second chance sometimes, and this means that the Nitro Reel spins again to give you a new symbol.

You trigger the bonus round by landing 3 to 6 scatters anywhere on the reels. This gives you 10, 15, 20 or 25 free spins, respectively, and you can re-trigger the feature in the same way. Before the bonus round plays out however, a random symbol will be chosen as the “scatter paying symbol”.

This chosen symbol can land anywhere and create winners, but you will need to land at least 3 to create a scatter win. The best feature of the bonus round is the sticky Nitro Reels. Every Nitro Reel you land becomes locked in place for the duration of the bonus round, and the Winning Respins can keep the feature going for a good while here.

The 200 Spins Nitropolis Experience

This is one of those games where it really helps to see the features in action to fully understand how it all works. We therefore strongly recommend that you check out the highlights video we’ve made from our 200 spins test session. It comes with plenty of Nitro Reels action, and the bonus round is triggered around 1 minute into the video.

Review Summary

Since the Megaways engine was such a huge success, it’s only natural that other developers are testing the waters with alternative versions of that popular mechanic.

Nitro Reels™ is a clever innovation from ELK Studios, but it will probably come across as somewhat confusing at first. Especially when it’s combined with the winning respins, but pretty soon you’ll get the gist of it.

In practice, Nitropolis runs like a Megaways game on crack because of the insane amount of potential winning ways available here. We are unsure if this trademarked engine will have mainstream appeal however, as the gameplay feels kind of cramped compared to Megaways engine slots. The 10,000x potential is solid enough, but not extraordinary with this many paylines, and it will be interesting to see how the Nitro Reels innovation is received in the community.

Pros

• Innovative Nitro Reels™ mechanic
• Up to 85,155,840 ways to win
• Winning symbols hold & respin
• Bonus round with scatter wins and sticky Nitro Reels
• Medium to high volatility and 10,000x max win potential

Cons

• Feels a bit cramped with all the symbols packed together

If you appreciate Nitropolis you should also try:

Star Clusters Megaclusters - might not come with a similar theme as the game at hand, but the innovative Megacluster engine packs a lot of symbols into the reel positions in a somewhat similar fashion. You will also benefit from a progressive multiplier wild here, and a bonus round where payouts up to 23,000x is possible.

The Dog House Megaways - is a high-powered alternative if you like games about animals and dogs. You can get up to 117,649 winning ways here, and you’ll benefit from multiplier wilds and a sticky wilds bonus round.

You can also get a raining wilds bonus round, and payouts up to 70,000x your stake is possible in this highly volatile Pragmatic Play title.

Punk Rocker - also comes with a very different theme than the game at hand, but the xWays mechanic is somewhat similar to the Nitro Reels engine. “Only” 46,656 ways are available at full capacity here however, as each xWays symbol can hold between 2 and 4 symbols only. The volatility is high, and wins hovering above 15,000x is possible in this NoLimit City creation.
