Nitropolis Slot Review

Where Can I Play Nitropolis Slot?

ABOUT Nitropolis

We at The Slot Buzz love ELK Studios. We adore a creative game developer, and ELK excel at it. There was the heist-themed Lake’s Five and the vampire slot Blood Lust. Instead of mad humans populating their Mad Max type setting, ELK has clans of animals fighting it out for the remaining green nitro fuel in a futuristic cityscape.

It’s a wacky game with amazing industrial graphics and a crazy guitar-electro soundtrack. Although the theme is one of the classic slots, the gameplay is quite conventional. Fans of high variance slots will enjoy this game, and the top 10,000x payoff is worth following.

RTP, Variance, and Highest Payout

Nitropolis, like ELK’s Gold-series slots, is a ,. Big winnings of 1,000x or more (and anything close to the 10,000x top reward) are only really attainable when you hit the proper combination of free spins and Nitro Reels in the bonus round, so don’t expect too much in the regular game. This is a High Variance game with an RTP of 96.1 percent, which is normal for ELK games, and the minimum bet is $0.20.


The game’s story revolves around four animal gangs fighting for Nitro fuel. They do it against a stunning industrial cityscape. Here are the four card suits. The Doberman dogs pay 5x for 5 of a kind, whereas gang logos, cats, bugs, and mice pay 3–3.6x apiece for a full line.

Note the Wild symbol which substitutes for all other symbols to generate winning lines, and the engine which is a scatter symbol to get free spins.

Gameplay and Specs

The features aren’t groundbreaking, however it’s worth noting that Nitro Reels can grow the reel set from 4,096 win ways to over 85 million! How it works:

Nitro Reels

There are 4,096 ways to win on six reels and four rows. If you get two symbols in a row, you get Nitro Reels. More symbols mean more win ways, up to 85,155,840 in total. Nitro Reels also has extra win methods and random re-spins following a losing spin.

This is a nice feature that keeps things interesting while you wait for the bonus round.

Respins Pros

The winning symbols will respin after each winning spin, while the rest will remain fixed. Respins continue until a non-winning spin.

Bonus Spins

Find the engine Scatter to activate the Bonus Game. A scatter (or three or more) will trigger 10, 15, 20, or 25 free spins. Before the free spins begin, one of the icons is chosen at random as the Scatter symbol, giving you extra chances to win.

The free spins can be retriggered up to 50 times.

Most importantly…

Nitro Reels always lock into place on the reels, so your enlarged reels gameplay is fixed for the duration of free spins, potentially improving the paytable substantially.


This slot game looks and plays great. An engaging story and dynamic gameplay keep things fresh even in the base game. Expansion reels drive tremendous win possibility, especially in the bonus round. We recommend this game to fans of high-speed action. Those seeking regular-paying slots should look elsewhere.
