Topped with the X-iter feature, Nitropolis 4 is the most thrilling slot game in the series to date!

โญ How to Play Nitropolis

Nitropolis slots feature 6 reels in 4 rows. The true spice of the game is found in the Nitro Reels. The Nitro Reels have various features, but most importantly, they create more ways to win. There’s also a bonus game feature: the bonus game will be prompted after triggering three bonus symbols.

Nitropolis slot machine has two modes: Normal Mode and Bonus Mode. Normal Mode refers to the regular gameplay, so your normal manual spins or auto spins. Bonus Mode refers to the bonus game, which runs with free bonus spins.

There’s a counter at the top of the reels. This counter indicates the ways to win from left to right. The counter starts from 4096 by default and grows rapidly from Nitro Reels’ multipliers.

Nitropolis pays out winnings on consecutive reels starting from the left reel. The game only considers the highest winning combinations of matching symbols for active play lines. After the winnings have been paid out, the winning symbols will respin, whereas the remaining symbol positions, including the nitro feature symbols, stay as they are. The respin feature will trigger until there aren’t any winning combinations on the reels.

Nitropolis features manual spins and auto spins functions.

Nitropolis Basic Symbols

There are 12 different basic symbols on Nitropolis: the letters J, Q, K, and A; an emblem for each of the four Nitro Gangs; and a rat, pug, cat, and dog to represent each gang, respectively.

Wild Symbol

Nitropolis slot game has a wild symbol that’s portrayed by a mushroom cloud symbol in the first game of the series. In Nitropolis 2, 3, and 4, the wild symbol is depicted by toxic cocktails among other things. The wild symbol can act as any standard symbol that’s absent from the otherwise winning combination. Wild symbols can’t replace a bonus symbol and, therefore, can’t trigger the bonus game.

You can, however, have a Nitro Reel with wild symbols in it. It’s a relatively rare occurrence, but it does happen.

Bonus Symbols

In modern online slots, any bonus games with a free spins feature usually provide the most exciting moments. The special symbols you want to look out for in Nitropolis slots game are engines. The symbol can also appear on Nitro Reels, though it won’t have multipliers like the regular symbols.

โญ Nitro Reels – Core of the Gameplay

Nitro Reels are probably the most exciting feature of Nitropolis slots game. Nitro Reels are special types of reels that appear occasionally. The special Nitro Reels take up the space of two symbol positions and contain from 4 to 12 identical symbols. There are numbers on top of the Nitro Reels, which indicate the number of identical symbols within the Reels. For instance, a Nitro Reel that has the number 10 on top of it contains 10 identical standard symbols.

If a Nitro Reel is included in a winning combination, the wins will be collected, after which the included symbols and the now sticky Nitro Reels respin. This respin feature can result in further winnings and will continue until there are no combinations of winning symbols.

Special Nitro Reels can appear on your regular spin, but they can also appear randomly after two symbols are stacked on top of each other respin. Nitro Reels can also randomly increase during a respin, between free spins, or even at the end of a spin. When this happens, an ‘Upgrade’ text will appear on the reel.

Nitro Reels will occasionally have a respin. This is easily spotted by the ‘Second Chance’ text that pops up on top of the reel.

โญ The Bonus Game Feature

Getting three or more bonus symbols will trigger the Nitropolis bonus game. The bonus rounds are essentially free spins. The number of free bonus spins depends on the number of symbols that triggered the extra game, varying from 10 to 25. These free bonus spins can also trigger a new set of bonus rounds – if you get three or more of the required special symbols.

โญ Different Versions of Nitropolis Slot

Elk Studios decided to develop the Nitropolis slot game further and introduced further sequels or spinoffs: Nitropolis 2, Nitropolis 3, and most recently Nitropolis 4. The games were released in a relatively short timeframe, and feature the same furry friends from the original game. Nitropolis 2 and Nitropolis 3 are somewhat different from the original game, making the gameplay spicier. There are also some updates on the graphics, and for example the wild symbols vary depending on the version you’re playing. Otherwise, the versions of these online slots follow in the footsteps of the original game.

Nitropolis 4, the latest addition to the Nitropolis slots game family, was released in late February 2023.

Nitropolis currently has four different versions, last of which was released in 2023.

Elk Studios have released multiple versions of Nitropolis, adding a bit more spice to each new version while still staying true to the spirit of the first game.

Nitropolis 2

Nitropolis 2 is just as chaotic and wild as its predecessor. The game has even more features than the original, introducing over 191 million ways to win. Compared to the original slot game, the sequel has a lower RTP of 95%. It’s a high-volatility online slot that introduces a new Nitro Booster feature. The Nitro Booster is the most notable difference in an otherwise familiar base game.

Nitro Boosters are separate reels located above the main reels. Nitro Booster reels have altogether 8 different features, 6 of which affect the Nitro Reels:

  • โšก Nitro Wild: All symbols within the Nitro Reel will land as Wild Symbols.
  • โšก Nitro Match: As the name suggests, Nitro Match will match the symbols in an existing Nitro Reel with a payout symbol on the adjacent reels to the left.
  • โšก Nitro Upgrade: Same as the Upgrade feature in the original slots.
  • โšก All Wild: A feature that functions like Nitro Wild, but affects all Nitro Reels. This feature will override the following All Match and All Premium features.
  • โšก All Match: Same as Nitro Match, but applies to all the Nitro Reels.
  • โšก All Premium: All symbols within Nitro Reels will have one of the top four highest-paying symbols.

There are also two features that affect the main reels:

  • Both Ways: All ways will pay from left to right and vice versa. Both Ways stay sticky until there are no more respins or wins.
  • Respin: You’re winning respins for the affected reels.

Nitropolis 3

Nitropolis 3 slot introduces the almighty Sergeant Nitro Wolf, an Avalanche feature, the Safety Levels, Green Nitro feature symbols, Big Symbols, the Big Nitro Reels, and the Super Bonus Game. Compared to the usual 6 reels in 4 rows, Nitropolis 3 introduces expanding rows that further improve the chances of winning. The RTP is at 95%, there are millions of ways to win, and the hit frequency is 19.2%. The new features bring the following changes to the slots:

  • โšก Avalanche: All the symbols that are a part of a win explode, leaving room for additional symbols to drop down from the top. This feature can continue until there are no more matching symbols to score a win.
  • โšก Big Nitro Reels: These massive reels of big symbols cover the space of six symbols and contain from two to six 2 x 2 payout symbols.
  • โšก Safety Levels: The Safety Level is a new feature within the Bonus Game. For every new free spin within the bonus rounds, the Safety Level advances one row.
  • โšก Super Bonus Game: An upgrade to the familiar bonus game. This feature is triggered by a combination of super bonus symbols and regular bonus symbols. The Super Bonus feature is played exceptionally both ways and with 8 rows.

Nitropolis 4

Nitropolis 4 is the latest addition to the slot game family. Elk Studios released the new version of the Nitropolis slot machine on February 23rd. The game has a lower RTP of 94% and hit frequency of 18.1%, making the game the most volatile one yet. However, the maximum win is also increased to an astounding 2.5 million.

Nitropolis 4 features the familiar animal gangs and exciting game mechanics introduced in the previous versions.

Released on February 23rd 2023, Nitropolis 4 is the latest addition to the Nitropolis slot game family.

You can play Nitropolis 4, the latest Elk Studios slot, as a free demo version.

โญ Nitropolis Casino Bonuses

As of March 2023, Nitropolis series are not staple casino games at US online casinos. Because the games are not available for real money casino gaming at licensed US casinos, there are no deposit bonuses to claim at the moment. When Nitropolis becomes more widely available in the US, you can claim a welcome bonus or free spin bonus at your chosen online casino to play with more.

Some of the best casino bonuses have a low minimum deposit or no deposit required at all! You can find plenty of high-value casino bonuses at BonusFinder US.

โญ Visual Features of Nitropolis Slot Machine Game

Let’s be real, many friends of slots often end up trying new slot games after being drawn in by the game’s visuals. Nitropolis is an absolute standout of a game in that aspect: the game showcases quirky post-apocalyptic art. Unlike your regular run-of-the-mill online slots, Nitropolis is truly dedicated to its theme, captivating the player in a matter of seconds.

The biggest eye-catchers of Nitropolis have to be the different animal clans. With quirky names like Rogue Rats, Pug Thugs, and Dirty Dawgs, and the proper artwork to accompany these mammal misfits, the initial impression of the slot is that of bewildered amusement.

Visually, Nitropolis is a far cry from your traditional three-reels or Vegas slots. With all its visual quirks, the game can initially feel a bit overwhelming. Luckily, that feeling passes after a couple of spins, and suddenly you find yourself immersed in the Nitro gangs.

โญ Nitropolis Strategies

As mentioned at the very beginning of this article, Nitropolis slot machine is a high-volatility slot. So despite the interesting features, the enormous numbers of different winning ways, and the possibility of triggering the free spins bonus rounds, you could play the game for a long while without any winnings.

The base game has a hit frequency of 19.8%, meaning that you can expect to win on approximately every fifth spin. Whereas high-volatility gameplay makes the stakes higher, playing any online slots for a long period of time without notable winnings can get dull.

Our recommendations for a strategy? Manage your expectations with this game: there’s always a chance to win big, but know that you could spend a lot of time waiting for that big win to happen. Keep an eye on your bankroll, too.

โญ Final Thoughts on Nitropolis

Elk Studios outdid themselves: Nitropolis and its upgraded versions are a breath of fresh air among online slots. The games are a ton of fun, quirky, and exciting. The graphics of the slots are impeccable, and the concept is well thought out and incorporated in all aspects of the slots.

Similar to other slots of high volatility, long periods of time could be spent without a notable win, which could make the gameplay dull in the long run. However, if luck is on your side and you do win, the slots quickly become exhilarating.

Some of the best online casinos in the US have yet to include Nitropolis and its successors in their game libraries. We’re confident that Nitropolis’ debut in the American online casinos is only a matter of time.

If you want to know what the buzz is all about, give Nitropolis a spin! You can try it out for free on our Free Games page.
