Nitropolis 3: Slot Review

If you are familiar with ELK Studios’ Nitropolis series, you know it is set in a dystopian city where four animal clans compete for Nitro fuel. In this post-nuclear world, the clans have fled the city for a tropical beach, possibly because Sergeant Nitro Wolf forced them out. Nitropolis 3 has a new setting that includes multiple features, increasing reels, and ELK’s largest potential seen so far.

Although the idea of post-apocalyptic life doesn’t usually include a trip to the beach, it can be a helpful way to recover from the chaos. ELK envisions a sandy beach with palm trees, beach chairs, huts, and toxic waste barrels. A crab is seen jumping in and out of the sand, and the game grid occasionally reveals the city in the background. However, compared to previous Nitropolis games, the visuals and soundtrack may not be as impressive. Trying N3 was similar to ordering a favourite burger, but without the cheese. While it might not be immediately satisfying, once the greasy and salty flavours burst on your tastebuds, any initial disappointment is forgotten.

Nitropolis 3

Nitropolis 3 has thrilling gameplay that can lead to big wins, and its high volatility makes it even more exciting. The game has an RTP of 95%, regardless of whether you play in regular mode with bets ranging from 20 p/c to £/€50 per spin or in X-iter mode with various prices. Please note that this message doesn’t talk about fast food; it only discusses Nitropolis 3.

The panel of the game grid consists of 6 reels and 4 rows, offering 4,096 ways to win. To win, you need to get 3 to 6 matching symbols in adjacent reels which pay from the left most reel and sometimes from right to left. The game has three types of regular pay symbols: J-A lows, four clan logos as mid-pays, and four animal character symbols as the highs. If you land a six symbol combo, you can get different payouts depending on the type of symbol: 0.3x for the lows, 0.8-1x for the mids, and 2-5x for the highs. The game also has wilds and pay symbols that come in four different sizes: normal 1×1, Super 2×2, Mega 3×3, and Mega 4×4. Bigger symbols are counted as the number of 1×1’s they are made up of.

Nitropolis 3: Slot Features

Nitropolis 3

Currently, Nitropolis 3 seems typical, but it contains numerous special symbols and features that promote progress. One of these features is the Avalanche, which clears winning symbols and fills gaps with new ones while also adding a row. The Avalanches keep recurring if consecutive wins appear, but the number of rows can only reach a maximum of 8.

Nitro Reels

Part three introduces Big Nitro Reels, which are larger and cover six symbol positions. They can contain 2, 3, 4, 5, or 6 2×2 sized symbols. Similar to Nitro Reels, Big Nitro Reels will also stay on the grid and respin when they contribute to a win. Nitro Reels, on the other hand, cover two symbol positions and contain either 4, 6, 8, 10, or 12 instances of a single symbol type.

Special Symbols

Various effects can be triggered by special symbols in any position, including the:

  • Redrop – The bonus symbols and Nitro feature symbols will still be present for the redrop, but only the Nitro Reels will respin.
  • Both Ways – The game pays out for winning combinations that occur both from left to right and from right to left.
  • Nitro Match – When Nitro Reels appear on reels next to or next to each other with Nitro Match, they will display a paying symbol that matches the one on the neighboring reel.
  • Nitro Upgrade – When Nitro Reels appear on the same or next reels as this symbol, they will expand and hold additional symbols.
  • Nitro Wild – If there is a Nitro Reel symbol, all symbols on the same or neighboring reels as this symbol will be substituted with wilds.

Bonus Game

If you land 3, 4, 5, or 6 Zeppelin scatters, you’ll be given 8, 12, 16, or 20 free spins respectively. During the bonus game, all Nitro Reels are sticky and will remain in place, even when new ones appear, creating a stacked effect. For every winning free spin, the safety level increases by one row, with a maximum of 8 rows. This means that the next free spin will start at the current safety level height. If you trigger free spins with at least one Super Bonus symbol, you can play the Super Bonus Game. The Super Bonus Game has 8 rows and Both Ways activated. You can retrigger both free spin bonus rounds.


Nowadays, it is quite rare to find an ELK game without an X-iter menu. Enabling X-iter mode allows users to play Nitropolis 3 with the following options:

  • Boosted Bonus Chance – You can pay twice the bet amount for a spin that has double the chance of triggering the bonus game.
  • Big Nitro Reel – You are guaranteed to win 10 times your bet if you spin with a Nitro Reel.
  • Nitro Match – You can activate a spin with a Nitro Match and Both Ways guarantee by betting 25x the initial bet.
  • Bonus – To enter the free spins, you need to place a bet that’s worth 100 times the original amount.
  • Super Bonus – To unlock the Super Free Spins bonus game, you need to place a bet that is 500 times the original amount.

Nitropolis 3: Slot Verdict

Nitropolis 3 combines ELK’s strengths, including expanding reels, more winning ways, unique symbols, X-iter betting options, and unconventional themes. It’s a mix of ELK’s past achievements and can be likened to the Gold Series. Sometimes, it seemed like we were experiencing a lot of Kane’s game model instead of the unique Nitropolitan future that we’re used to. Some people might think that ELK chose an easy route by reusing Kane’s game, but the advantages are much greater than the disadvantages.

The gameplay is smooth and comes with many extra features that can activate or improve each other at any time. With the additional rows in Nitropolis, there is even more space for gameplay. While some may think this is excessive, Nitropolis 3 offers more potential than before. It is an understatement to say that the game has not stayed the same.

ELK’s latest slot game, Nitropolis 3, has a maximum win of 50,000x, making it their highest paying slot game yet. The previous games had a win cap of 10,000x, which seemed low compared to the vast number of ways to win (over 190 million in Nitropolis 2). The criticism seems to have been taken to heart, and the new game is sure to impress when it hits its win cap.

Playing Nitropolis 1 or 2 was like being immersed in a dystopian world that was both enjoyable and imaginative. Nitropolis 3 has some enjoyable moments too, but the presence of the character Kane takes away from the immersion. However, Nitropolis 3 is a great example of the creativity, chaotic features, and potential that ELK Studios has to offer.
