Nitropolis 2 Slot Overview

In this new casino slot from ELK Studios, we get to take part in a dear reunion with the futuristic city Nitropolis. Where the previous Nitropolis slot really captured the hearts of many with its innovative features, and the Nitro Reels was truly the highlight during the spins. With its atmospheric theme and the mystery that permeated the slot, we really took part in an entertaining moment in front of the screen. Most things are the same in this place, where the gangs become increasingly more violent as their beloved Nitro gas becomes increasingly more difficult to seize.

Even though the various gangs do what’s best for their loved ones, the outsiders are feeling more unsafe in this city and this is something that must come to an end. Sergeant Nitro Wolf is the new character who appears in this slot, where he uses all the methods required to clean up this city from criminal gangs. He has so far managed to capture the Rouge Rats, but the three gangs Pug Thugs, Gritty Kitties and Dirty Dawgs still spread fear in the streets. It's a risky mission for Sergeant Nitro Wolf to take on, but it can certainly be a great reward in the end.

Base game

Nitropolis 2 is a slot from ELK Studios that has 6 reels and 4 rows. The number of ways to win starts at 4096 and can increase to an incredible 191'102'976. A completely crazy number of ways to win and it beats the predecessor's 85'155'840 ways to win by good margins. Like its predecessor, it is once again a high volatility, where this time it is 8 out of 10. You can choose between making a of 0.20 and a of 100, which can give very festive wins with the unchanged maximum win of 10000X the bet.

When we first were introduced to the Nitro Reels and its potential, it was love at first sight. That the slot was then also topped with a lot of other features, made the game felt close to perfect. When ELK Studios then comes with news that a sequel is on its way, the idea that quickly popped up was, what can they add to a game like this? On further consideration, the thoughts were struck that they are in a fantastic flow for the moment when it comes to game development as in eg Cluster Slider and Bompers, so they have probably figured out something ingenious this time as well. The features that we can take part in are Wild Symbol, Nitro Reels, Winning Respin, Nitro Booster, Bonus Game and X-iter. Let's find out what symbols you can expect to see.

Nitropolis 2 Slot Information

The game design of Nitropolis 2 consists of a futuristic world, where in the background of the reels you can see tall buildings with futuristic light. To the left you see a large picture showing the Sergeant Nitro Wolf, who certainly proves that it is a new sheriff in town. To the right you can see a Don’t poop here sign, where an uninterrupted and badass dog completely ignores this. When it comes to the reels, there are 6 of them and 4 rows, above these there is also room for the various Nitro Boosters that you can take part in.

The lower paying symbols consist of J, Q, K and A graffiti painted. The medium paying symbols consist of emblems from the various gangs Pug Thugs, Gritty Kitties, Dirty Dawgs and also the Pest Control. The higher paying symbols are the leaders of each group. This also includes Sergeant Nitro Wolf, who in addition to his very cool name also has a very cool look, which means that he can very likely be placed in the category of cool guys don’t look at explosions. The game's Wild Symbol consists of a Don’t poop here sign that has the text Wild on it. The game's scatter symbol consists of a pimped police car with the registration plate Salty Dog, where the text Bonus is displayed in the background of it. If you are looking to play mobile slots online, Nitropolis 2 and other games from ELK Studios are a perfect choice. This is because they ensure that their slots are implemented in both HTML5 and java scripts to work on as many devices as possible. It's now time for us to find out what features we can take part in, so let's dive into that section.

Nitropolis 2 Slot Features

During the spins in the Nitropolis 2, the lucky player can win up to 10000X the bet. This will be possible with the help of the features Wild Symbol, Nitro Reels, Winning Respin, Nitro Booster, Bonus Game and X-iter.

Bonus Game - Nitro Upgrade feature

Wild Symbol

This symbol helps to create more winning combinations by substituting for other symbols. The only symbol it does not substitute for is the scatter symbol.

Nitro Reels

This symbol always covers 2 positions on the reel on which it lands, and above it you always see one of the numbers 4, 6, 8, 10 or 12. This shows how many of the payout symbol displayed that this Nitro Reel contains.

Winning Respin

When you get a winning combination, all participating symbols and Nitro Reels will Respin. This continues as long as new winning combinations are created.

Nitro Booster

Above each reel, 8 different Nitro Boosters can land randomly with various features that just like its name can give a real boost to the winnings. The 8 Nitro Boosters you can land are the following:

Respin = This will give you a Respin, but before that happens, all Nitro Reels and scatter symbols will be locked in place.

Both Ways = This will give wins from both left to right and right to left.

Nitro Wild = If you land Nitro Reels under this symbol, they will show Wild Symbols.

All Wild = With the help of this, all landing and sticky Nitro Reels will get Wild Symbols.

Nitro Match = If you land Nitro Reels under this symbol it will be matched with any of the symbols that the reel on the left has.

All Match = This will match all Nitro Reels with a symbol that the reel on the left has.

Nitro Upgrade = If you land Nitro Reels under this symbol, the number of symbols the Nitro Reel contains will increase.

All Premium = With the help of this, all Nitro Reels that land will contain higher paying symbols.

Bonus Game - Both Ways feature

Bonus Game

When you spin the reels and land 3 or more scatter symbols, the Bonus Game is activated. You are then welcomed with free spins and depending on whether you landed 3, 4, 5 or 6 scatter symbols, you get 10, 15, 20 and 25 free spins respectively. Even if there is a chance to get many free spins from the start, you can also during these spins manage to get more of them. You get the same number of free spins per number of scatter symbols as when activating the feature.

The thing that makes the spins within this feature extra spectacular compared to the Base Game is that all the Nitro Reels that land are sticky during the remaining spins.


X-iter is a feature that gives you as a player the opportunity to choose from 5 different game modes. This so that you can tailor your spins as well as possible and immediately can take advantage of the game modes that you prefer the most.

You pay and get the following:

5X the bet = You are guaranteed to get a winning spin.

25X the bet = You get 3 spins where you are guaranteed to land either a bonus or feature symbol on all positions on the Nitro Booster.

100X the bet = (Buy Bonus) You get to take part in the bonus game, where you activate it by landing 3 scatter symbols.

200X the bet = (Big Bonus) You get to take part in the bonus game, where you activate it by landing 4 scatter symbols.

500X the bet = (Super Bonus) You get to take part in the bonus game, where you activate it by landing 3 scatter symbols. You also get to start with 12 Nitro Reels which is the maximum.

Nitropolis 2 Slot Conclusion

Creating sequels is seldom an easy task as you have a lot of performance pressure on you. The hopes are usually sky high as the predecessor was probably a success. ELK Studios handles this task phenomenally and comes here with a golden touch to a previous success slot. They have really delivered a large number of first-class slots in recent times, where we have Bompers, Cluster Slide, Katmandu Gold, Knockout Diamonds and many more. They certainly ride a wave that seems to be from a wave simulator as it has been going on for a long time, but it's nice that they take the opportunity to upgrade Nitropolis.

This is a slot that has a very high volatility and if you are a player who wants winnings to land frequently, this is not the right slot. It can take a very long time before the bigger wins start to come and also the right amount of scatter symbols required to activate the Bonus Game. Once this happens, you are up for a treat and although there are many different things to keep track of regarding the Nitro Booster's various functions, you learn it quickly. ELK Studios has taken the number of possible ways to win to a new level where this time we can get up to 191'102'976 ways to win and the maximum win that the player can get is the unchanged 10000X the bet. Which is a high potential max win, but the more the marrier, so a little uplift of the max win would have been nice. It is otherwise a very fascinating and captivating world that they have managed to create, where in addition to exciting mechanics, there are also well-designed symbols and effects that you get to experience.

An exciting gaming adventure certainly awaits in this new online slot Nitropolis 2 where a high risk among the various gangs can result in great prizes. Why the Nitro gas is very popular in Nitropolis is quickly confirmed as it can help create very exciting features during your spins.
