This fun game features chaotic gameplay, great graphics, and a whopping 85 155 840 ways to win<\/strong>. While initially overwhelming, the game is pretty easy to understand once you start spinning. Here’s the basic information about this whimsical slot to get you started:<\/p>\n Since the original game’s release in 2020, Nitropolis has quickly grown into its own branch of online slots. Nitropolis now features five games in the main series and a handful of spinoff games.<\/p>\n Nitropolis is a eccentric online slot game with funky features and engrossing gameplay. Check out our review of this fun game below!<\/p>\n<\/div>\n Nitropolis slots feature 6 reels in 4 rows<\/strong>. The true spice of the game is found in the Nitro Reels feature. Nitro Reels contain 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<\/strong>.<\/p>\n There are 12 different basic symbols<\/strong> 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.<\/p>\n Elk Studios Nitropolis slot game has a wild symbol<\/strong> that’s portrayed by different symbols depending on the Nitropolis edition. 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 bonus games.<\/p>\n You can, however, have a Nitro Reel with wild symbols in it. It’s a relatively rare occurrence, but does happen.<\/p>\n In modern online slots, any free spins bonus game feature usually provides the most exciting moments. The special symbols you want to look out for in the Nitropolis slot online game are engines. The symbol can also appear on Nitro Reels, though it won’t have Nitro multipliers like the regular symbols.<\/p>\n Nitropolis base game features exciting gameplay and bonus features.<\/p>\n<\/div>\n Nitro Reels are probably the most exciting feature of the Nitropolis slots game. Nitro Reels are special types of reels that appear occasionally. The special Nitro Reels occupy two symbol positions and contain from 4 to 12 identical symbols.<\/strong> There are numbers on top of the Nitro Reels, which indicate the number of identical symbols within the Reels. For instance, a Nitro Reel with the number 10 on top of it contains 10 identical standard symbols.<\/p>\n If Nitro Reels land in a winning combination, the wins will be collected, after which the included symbols and the now sticky Nitro Reels respin and stay sticky for the remaining spins. Sticky Nitro Reels will still have the same number of other symbols when spinning. This respin feature can result in further winning combinations, and the remaining free spins continue until there are no combinations of winning symbols. With these sticky Nitro Reels active, the number of winning combinations rapidly climbs to millions.<\/p>\n 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. Sticky 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.<\/p>\n Sticky Nitro Reels occasionally have a respin. This is easily spotted by the ‘Second Chance’ text that appears on top of the reel.<\/p>\n Getting three or more special symbols will trigger the Nitropolis bonus game.<\/strong> The bonus rounds are essentially free spins. The number of free spins depends on the number of symbols that triggered the extra game, varying from 10 to 25. This free spins feature can also trigger a new set of bonus rounds – if you get three or more of the required special symbols.<\/p>\n 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.<\/p>\n<\/div>\n Elk Studios has introduced various Nitropolis spinoffs: Nitropolis 2, Nitropolis 3, Nitropolis 4, and most recently, Nitropolis 5. The games feature the same furry friends from the original game. The later versions of Nitropolis are slightly different from the original game, making the gameplay spicier. There are also some graphics updates; 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.<\/p>\n Nitropolis 2 Slot<\/strong> is just as chaotic and wild as its predecessor. The game has more features than the original, with over 191 million ways to win. Compared to the original slot game, the sequel has a lower RTP of 95%<\/strong>. It’s a high-volatility online slot with a new Nitro Booster<\/strong> feature. The Nitro Booster modifiers are the most notable differences in an otherwise familiar base game.<\/p>\n Nitro Boosters are separate reels located above the main reels. Nitro Booster reels have altogether eight different features, 6 of which affect the Nitro Reels:<\/p>\n Two features affect the main reels:<\/p>\n Nitropolis 2 was is one of the most exciting Elk Studios games. It’s an upgrade to regular Nitropolis and introduces new features, such as Nitro Wild and Nitro Upgrade.<\/p>\n<\/div>\n 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 on every spin or symbol drop. The RTP is at 95%<\/strong>, there are millions of ways to win, and the hit frequency is 19.2%<\/strong>. In addition to the familiar features like nitro reels, these new features bring changes to the slots:<\/p>\n Nitropolis 3 features safety levels and a thrilling Super Bonus game, offering even more opportunities to win big.<\/p>\n<\/div>\n Although Nitropolis 4 isn’t widely available in the US, you can play the demo game (and other free slots from Elk Studios) on Elk Studios’ website.<\/p>\n Excluding the spinoff games from the Battle of Nitropolis series, Nitropolis 4 is the latest main game in the Nitropolis slot game family. Elk Studios released the new version of the Nitropolis slot machine in early 2023. The game has a lower RTP of 94% and a 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.<\/p>\n Nitropolis 4 features familiar animal gangs and exciting game mechanics introduced in the previous versions.<\/p>\n Line up those Nitro Reels! You can play Nitropolis 4, the latest Elk Studios slots, as a free demo version.<\/p>\n<\/div>\n In 2024, Elk Studios announced a massive game project spanning over the course of five months. The project, titled the Battle of Nitropolis, introduced various new online slots set in the Nitropolis realm.<\/p>\n The Battle of Nitropolis consists of the following online slot titles:<\/p>\n Let’s be honest, many friends of slots often end up trying new slot games<\/a> 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 seconds.<\/p>\n The biggest eye-catchers of Nitropolis have to be the different animal clans. With quirky names like Rogue Rats, Pug Thugs, and Dirty Dawgs, as well as the proper artwork to accompany these mammal misfits, the initial impression of the slot is that of bewildered amusement. These animal clans face a fierce fight for Green Nitro, the sought-after fuel for their cars.<\/p>\n Visually, Nitropolis is a far cry from your traditional three-reels or Vegas slots. With all its visual quirks, the game can initially feel overwhelming. Luckily, that feeling passes after a couple of spins, and suddenly, you find yourself immersed in the Nitro gangs.<\/p>\n Wondering what’s the best way to play Nitropolis? BonusFinder gambling experts have gathered some tips and tricks on how to play online slots.<\/p>\n<\/div>\n As of March 2025, 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. 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.<\/p>\n Some of the best casino bonuses have a low minimum deposit or no deposit required! You can find plenty of high-value casino bonus codes at BonusFinder US.<\/p>\n As mentioned at the beginning of this article, the Nitropolis slot machine is a high-volatility slot. So despite the exciting 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.<\/p>\n The base game has a hit frequency of 19.8%, meaning that you can expect to win on approximately every fifth spin. While high-volatility gameplay increases the stakes, playing online slots for a long time without notable winnings can get dull.<\/p>\n 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. Keep an eye on your bankroll, too.<\/p>\n The game studio behind Nitropolis hails from Sweden. ELK Studios was founded in 2013, and quickly established its spot as one of the top online casino game developers in Europe. <\/p>\n Games from ELK Studios have some of the best graphics in the online casino industry. This is very refreshing from a player’s point of view: online casino games, especially slots, tend to feature a lot of overlapping themes. Games from ELK Studios have beautiful graphics topped with unique game mechanics. Check out Elk Studios games if you’re a fan of good, conceptual games!<\/p>\n Unfortunately, most games from Elk Studios have yet to take over American online casinos. Their games aren’t nearly as widely available as games from big names like NetEnt, IGT, or Pragmatic Play. That said, Elk Studios has been granted a New Jersey license in 2024 spring, so you can expect to see Nitropolis and other games from Elk Studios on NJ online casinos soon.<\/p>\n Elk Studios outdid themselves: Nitropolis and its upgraded versions are a breath of fresh air among online slots<\/a>. 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.<\/p>\n Similar to other slots of high volatility, long periods could be spent without a notable win, making the gameplay dull in the long run. However, if luck is on your side and you win, the slots quickly become exhilarating.<\/p>\n 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 will be a matter of time.<\/p>\n If you want to know what the buzz is all about, give Nitropolis a spin!
