Nitropolis 3 Slot Overview

With ELK Studios’ established game series, players will instantly find themselves in this dystopian urban setting where the games are set. However, their most recent installment is a bit different. Still, it continues the series’ post-nuclear storyline and intense gameplay, which becomes apparent as soon as players start playing the game. The catch of Nitropolis 3 is that it allows players to win as much as 50,000x for their wager.

The game features a post-nuclear world where four animal clans scurry around, trying their best to obtain Nitro so that they can fuel their vehicles. However, for some reason, the clans have fled the city and found themselves on a tropical beach, serving as the game’s new setting. While the city’s post-apocalyptic aesthetic may occasionally be seen behind the game grid, in ELK’s vision, this is a sandy beach lined with palm trees, loungers, beach houses, and containers holding radioactive waste. Still, ELK Studios is combining winning potential with a captivating story.

Nitropolis Slot Features

Avalanche Payouts and Added Rows

The Avalanche feature is the first on this list. The feature eliminates winning symbols from the panel and then fills the gaps with newer symbols while adding another row. If consecutive wins keep happening, avalanches will keep avalanching, although rows peak at 8 high. Consequently, this feature also generates more winning ways. Mentioned below is the total number of ways generated with the addition of each row:

  • 6×4 grid = 4,096 ways (default)
  • 6×5 grid = 15,625 ways (first avalanche)
  • 6×6 grid = 46,656 ways (second avalanche)
  • 6×7 grid = 117,659 ways (third avalanche)
  • 6×8 grid = 262,144 ways (fourth avalanche)

Nitro Reels

The miniature Nitro Reels have 2 symbol positions and can contain 4, 5, 8, 10, or 12 symbols. The larger Nitro Reels are comprised of six symbol positions that can hold 2, 3, 4, 5, or 6 symbols that are 2×2. Both types of Nitro Reels can add to the number of available ways, which means that players can unlock up to one million ways via a combination of the added rows and Nitro Reels.

Special Symbols

Special symbols can trigger a variety of effects and appear in any position. Such effects include:

  • Redrop: both the bonus and Nitro feature symbols become sticky, as the other Nitro Reels respin
  • Both Ways: every win pays from left to right and then right to left as well
  • Nitro Match: it results in symbols from Nitro Reels appearing on adjacent reels, which boosts the potential for winning
  • Nitro Upgrade: this increases the number of symbols in a Nitro Reel
  • Nitro Wild: it causes all the characters within a Nitro Reel to be replaced by wilds

Bonus Game

Hitting 3, 4, 5, or 6 bonus icons (also known as zeppelins) rewards you with 8, 12, 16, or 20 free spins. There are a few things that change here. For one, every Nitro Reel becomes sticky for the entire bonus game’s duration, which means that when new ones land, they are stacked on top of one another. The safety level adds one row for each winning free spin, which can go up to 8 rows high. This means that the following free spins begin at the existing safety level height. The Super Bonus Game is initiated if at least one Super Bonus symbol is utilized to trigger a round of free spins. Once started, the Super Bonus Game uses 8 rows, with both ways enabled. Both the bonus free spin rounds are re-triggerable.


Finding a game from ELK Studios that does not have an X-iter mode can be rare. By switching on X-iter, users can play Nitropolis 3 in the following ways:

  • Boosted Bonus Chance: at the cost of 2x the stake, one spin can have double the chance of triggering the bonus game

  • Big Nitro Reel: one spin that guarantees a big Nitro Reel, but for 10x the stake

  • Nitro Match: a spin in which both Nitro Match and Both Ways are guaranteed to activate for 25x the stake

  • Bonus: You can buy entry to free spins at 100x the stake

  • Super Bonus: at 500x the stake, one can buy access to the Super Free Spins bonus game (8 rows & Both Ways Pays)

RTP, Volatility, Betting Options, and Payouts

Nitropolis 3 can be highly volatile, bursting at any moment, with the RTP at 95%. Also, the RTP stays the same even when you play in regular mode, with stakes ranging from 20 p/c to £/€50 per spin. If you’re playing the X-iter mode, each of the five options comes with a different price tag. However, the volatility is locked at 7/10, which might be low when the enormous top payout is concerned. And, given that the hit rate is 19.20%, you will win around one out of every five spins.

The game grid begins with a panel consisting of six reels and four rows, which provide 4,096 ways of winning. Hitting three to six matching symbols on adjacent reels produces a winning combination, which typically pays from the left-hand side but can occasionally pay both ways. For example, J-A as lows, four clan logos as mid-pays, and four animal character symbols as the highs are all the three kinds of regular pay symbols.

When one lands a six-symbol combo, it pays out 0.3x for the lows, 0.8–1x for the mids, and 2–5x for the highs. There are four sizes available for wilds and pay symbols: normal 1×1, Super 2×2, Mega 3×3, and Mega 4×4. The larger symbols are counted as the quantity of 1x1s that make them up.

Gameplay Experience

When you first engage in a few play sessions, there are various elements to monitor and understand. Still, you can quickly understand them, and the gameplay variety makes it difficult to get bored looking at the reels. As a result, you will notice its slick gameplay, packed with visual extras that can spark and enhance one another at any given moment. Then there are those additional rows as well, giving Nitropolis 3 a lot more room to create excitement and keep you entertained. Then, of course, more space is welcome for those wild symbols, scatters, free spins, sticky nitro reels, symbol upgrades, both ways, and respins, all of which contribute to its enticing gameplay.

Nitropolis 3 Tips and Tricks

Everyone wants to know how they can win and make the most of their time with those iconic themed slot games. Playing Nitropolis 3 is the same as playing any other third-generation slot. Here are some untold strategies that will get you further into the game!

Play Higher Denominations

The goal of playing higher denomination bets is to maximize your potential winnings. Spins with higher denominations can be more profitable, yet they are risky. If you can only afford one high bet, your chances of winning might be reduced; you can really rake in those rewards if your luck manages to hold up.

When you are faced with the option of making two $1 bets or one $2 bet, it would be better to go with the $2 bet. That is because those higher denomination slots would pay a lot more. If your luck is dry, you will go through your budget quickly, so lower denominations should get you those extra spins if you want to play longer sessions.

Bet the Maximum

Many casino games draw in players by advertising the potential to win massive payouts. The same is true for Nitropolis 3, which gives players a chance to win 50,000x the wager. However, players must wager the highest possible amount to win the maximum potential payout.

Spins with lower stakes are entitled to the same stake multipliers used for larger stakes. However, the payout would be significantly less. If you only care about scooping huge wins, then placing bets with the maximum amount you can afford is one way to do it.

Test the Game Out

Numerous online casinos offer players free spins or the chance to play for fun without wagering any money. Likewise, you can play Nitropolis 3 without spending money, which can be an excellent chance to try new strategies or possible angles. So, if you feel unsure and want to understand the game’s bonus features more, give it a few spins during free play, and you’ll know how the game reacts to your bets.

Don’t Think of “Due” Payouts

Slots tend to be completely random, and online slots are powered by random number generators (RNG). This also implies that “hot” or “cold” streaks are non-existent, as each spin resets the chances. Consequently, remembering this fact can be important when playing slots. Never assume that a massive win is specific or due because you have not scored in prior rounds. While their system is not foolproof or guaranteed success, it could still make one feel a bit uneasy.

Know When to Stop

Just like any casino game, you need to delimit gambling from fun. It’s essential to consider your limits when playing, such as your budget or how much you can afford to lose. Please do not chase your losses too much to break even, as it could lead to even more losses. If you have some good wins, set a withdrawal goal and stop once you achieve it. Another important tip is to stop as soon as you think you are no longer having fun.

Final Verdict

Nitropolis 3 is an exceptional addition to its original series and the Elk Studios portfolio. It has plenty of action-filled gameplay with unique features and symbols like sticky nitro reels, both ways, X-iter, and several others, all of which serve to complement things even more. Hence, Nitropolis 3 is exciting, makes for a good payout, and never gets dull. When all its features are combined, items can take off, and when they do, one can quickly see how wins up to 50,000x are possible in this highly volatile release.
