Nitropolis slot (Elk Studios) – The world ceases to exist… So what happens next?

The four clans aim to get their hands (or pawns) on the precious green Nitro liquid that fuels their cars. One clan survives and will rule Nitropolis. Which family will you join?

You can say whatever you want to say about Elk Studios, but the theme is extraordinary and one to remember. And the gameplay? Also!

Number of paylines: 6 reels with at least 4 rows, 4096 to over 85 million ways to win (win all ways)

RTP and variance: 96,1%, Medium to High variance

Maximum win: 10,000 x the total bet, or $€1.0 million

Betting range: $€0.20 – $€100

Bonus features: Free spins, Nitro Reels

Casino Hipster verdict: HOT! Original, overwhelming, innovative and above all, great fun.

Nitropolis slot – Gameplay and Features

You start to play with 6 reels, with 4 symbols each, and you have 4.096 (4x4x4x4x4x4=4.096) ways to win, according to the win-all-ways mechanic.

The new Nitro mechanic

On top of that, Elk Studios has introduced the Nitro Mechanic (and applied for and received a trademark). It is possible to get Nitro Reels with 4, 6, 8, 10 or even 12 (!) identical symbols. These symbols are, as it were, stacked on top of each other.

A Nitro Reel covers 2 of the 4 positions on a reel. As there are 4 positions per reel, it is possible to get 2 Nitro Reels of at most 12 identical symbols on one reel.

In the end, 24 symbols can appear on four reels, 20 symbols on one reel and 14 symbols on one reel (Elk Studios has capped it). It brings you to a blistering number of 85.155.840 (over 85 million times) ways to win! Calculated as (24x24x24x24x20x14=85.155.840).


The high-paying symbols are the four clans, followed by the four logos of the clans. The low-paying symbols are A, K, Q and J.

Besides, you have Wild symbols (a bomb explosion) and scatters (a kind of an engine).

Nitro reels extra features

With the Nitro mechanic, you can get 4 up to 12 stacked symbols, thereby massively increasing the number of ways to win.

There are a few more attractive features, though.

You have the Nitro Reel Upgrade, which gives you a free respin at random moments and converts the current Nitro reel symbol into a higher-paying symbol.

Also, Elk Studios built the Second Chance Respin feature, where you get a free Respin and a second chance to grab a winning combo.

By the way, after a win, you get an extra free respin anyway. The so-called Winning Respin Feature continues until you fail to spin a bigger win or new winning combo.

But there is even more!

The free spins – locked Nitro Reels and Scatter Pay

You get 10, 15, 20 or 25 free spins if you spin 3, 4, 5 or 6 scatters. During the free spins, you can win extra free spins in the same way.

The free spins play the same as the main game, but there are two essential advantages.

You have the Locked Nitro Reels feature, where the Nitro Reels remain sticky for the remaining free spins.

With the Scatter Pay feature, a symbol is randomly selected for scatter wins.

Payout percentage (RTP)

The payout percentage of Nitropolis is 96.1%. It exceeds my critical 96% limit.

The variance (volatility) of Nitropolis is medium to high.

Elk Studios gives a score of 8 out of 10 for volatility. In other words, the variance is medium to high.

It goes with no surprise that you can win big, with the 85 million ways to win! I expect the top wins to be around 1,000x.

Other Elk Studios slots with similar volatility are The Grand Galore, Diablo Reels or the excellent Visitors slot.

So, who’ll like the slot? And who won’t?

Players looking for a slot that they have not seen before are at the right place! The gameplay does come with risk, though. Nitropolis is quite the volatile slot.
