Nitropolis 3 Slot (ELK)

ELK Studios has a new slot titled Nitropolis 3. It’s a new addition to their post-apocalyptic series that we have already gotten accustomed to.

Personally, I’m a huge fan of this developer, and I enjoy this series with no reservations. Let's explore Nitropolis 3 and see what players can expect from it:

Game Set-Up

Here, the grid is made up of 6x4 reels and 6,096 ways to win. As usual with ELK Studios slots, this one also comes with great features that include wilds, Avalanches, free spins, expanding reels, and Nitro Reels.

Betting and Prizes

As a real money gamer, I enjoyed a betting range of between $0.20 and $50 per spin.

For the top payouts, ELK Studios has given the slot up to $2,500,000 (50,000x the stake) which I find to be awesome, especially for a high volatility slot.

However, I’m a little disappointed with the low RTP of 95% that the developer has opted for.

Nitropolis 3 Slot Features

If there is a slot developer known for using creativity, then it must be ELK. The developer has given Nitropolis 3 a couple of excellent features, among them the common wild symbol.

As usual, the wild will help in substituting other regular icons, but not the bonus ion. It can also appear in both regular sizes, as well as larger sizes (up to 4x4).

With the help of ways to win, I managed to create some winning combinations, and this is how I triggered the Avalanches.  The beauty of this feature is that it removes the winning icons, and replaces them with new ones. The process will go on and on until there are no more new wins.

This is a great way to boost your ways to win and the game area (you may end up working with 6x8 reels), and I must commend ELK for the noble thoughts.

One of the most unique mechanics in the game is the Nitro Reel. The feature involves double-stacked symbols, which count as 4 -12 similar symbols. This is another feature that boosts the number of ways to win.

Nitropolis 3 also offers Big Nitro Reels, and these can fully cover the reels, giving way to up to 6 icons of 2x2 sizes.

Nitropolis 3 has modifiers as well, and each comes with its work. These modifiers are Nitro Wilds, Nitro Upgrades, Nitro Match, Both Ways, and Redrop.

The main feature for me was the free spins, and with the help of 3 to 6 scatters, I was rewarded with 8-20 free rounds.

Theme & Design

The slot has the same post-apocalyptic vibe where we get to see dogs and cats ruling the streets of a huge city. However, on this slot, we’re taking a holiday, but unfortunately, the beach in the background is littered with toxic barrels.

The symbols here include low pay Royals, alongside logos representing the four clans. Wild Toxic Signs and Zeppelin scatters serve as the feature symbols.


Nitropolis 3 is a great and interesting addition to this popular series. It has all the nice things that a modern player would be looking for. However, it's 95% RTP may work against it.
