About This Slot

Here at The Slot Buzz we are big fans of ELK Studios. We love a game developer who gets creative, and ELK are brilliant at that. Past glories including the heist-themed Lake’s Five and the vampire slot, Blood Lust. This time they have gone all post-apocalyptic on us, but rather than populating their Mad Max style landscape with deranged humans, ELK have clans of animals fighting it out for the remaning green nitro fuel in a futuristic cityscape.

It’s pretty bonkers stuff with suitably cool, industrial graphics and a crazy guitar-electro soundtrack pumping out at all times. The theme might be one of the original slots ones but the gameplay is pretty generic as we will find out. Nevertheless high variance slots fanatics will get a kick here and the top 10,000x payout is worth chasing.

RTP, Variance and Top Payout

Like their Gold-series of slots, Nitropolis is one of ELK’s high variance games. That means unlocking the big prizes will be tricky and the win distribution is pretty uneven – big wins of 1,000x or more (and anything close to the 10,000x top prize) are only really possible when you hit the right combination of free spins and Nitro Reels in the bonus round so don’t expect too much in the base game. The RTP is set a 96.1% which makes it fairly average for ELK games, and play starts from $0.20 per spin.

Symbols and Paytable

The narrative behind this game is built around four gangs of animals who fight for precious Nitro fuel. They do so against an impressive backdrop of an industrial cityscape. Low value symbols here are the four card suits. High value ones are the Doberman dogs which pay out 5x for 5 of a kind, and gang logos, cats, bugs and mice which pay out between 3 and 3.6x each for a full line.

Look out as well for the Wild which subs for all other symbols to form winning lines, and the engine which is the scatter symbol required to unlock the free spins round.

Gameplay and Features

As we mentioned earlier, the features here are not that ground-breaking, however it is worth noticing that with Nitro Reels you can expand the reel set from a standard 4,096 win ways to over 85 million! Here’s how it works:

Nitro Reels Feature

The game starts as a 4,096 win ways slot with six reels and 4 rows. During Nitro Reels, symbols land that cover two positions and contain 4 and 12 symbols themselves. More symbols means more win ways and potentially as many as 85,155,840 in total. Nitro Reels also comes with additional win ways upgrades and random re-spins after a non-winning spin.

This is a great feature and sits at the heart of the gameplay in Nitropolis and keeps things interesting whilst you wait to break into the bonus round.

Respins Feature

After EVERY winning spin, the winning symbols will respin, while all others are locked in their position. Respins keep going until there is a non-winning spin.

Free Spins Feature

Look for the engine Scatter to trigger the Bonus Game feature. Depending on the number of Scatters landed (3, 4, 5, 6), you can trigger 10, 15, 20, or 25 free spins. Before free spins start, one of the icons is randomly selected to be the special symbol that performs the role of the Scatter during the feature and gives you extra win potential.

It’s possible to retrigger the free spins so you can get up to 50 free plays at once.

And most importantly …

Nitro Reels always lock into their positions when they appear on the reels, which means your expanded reels gameplay is fixed for the duration of free spins, potentially enhancing the paytable dramatically. 

Our Verdict

This is a slot game that looks and plays fantastically well. It’s a great combination of a cool narrative and energetic gameplay that keeps things interesting even in the base game. The expanding reels mechanic is what really drives the big win potential, particularly in the bonus round. We recommend this game to anyone who enjoys frenetic high variance action. Those looking for casual, regular-paying slots play may want to look elsewhere.
