Nitropolis is a funny and thrilling online slots game that can keep you on the edge of your seat. While the standard layout is 6×4 with 4,096 ways to win, the nitro reels add more symbols to the screen, and thus more lines. The feature can turn any spin into a large payout, providing up to 85,155,840 ways to win.
The maximum jackpot goes up to $1,000,000 and the RTP is 96.10%. This can explain why Nitropolis slot machine is so popular.

How to Play the Nitropolis Slot Machine Online
The Nitropolis slot machine can seem a bit difficult to play at first, with its Nitro Reels feature and 85 million paylines. However, the truth is that it is actually very simple and straightforward. The controls are user-friendly and we will guide you through the entire process here:
1. Set the Coin Value
You can select the size of the bet from the coins icon in the bottom left corner. This will bring up a menu with stakes ranging from $0.20 to $100.
2. Spin the Reels
Once you have the stake set, you can press the large spin button located in the bottom right corner. This will start one round in the Nitropolis slots.
3. Start the Auto-spin Feature
If you want to let the game spin on your behalf for a few rounds, enable the auto function from the top. Choose between 10, 25, 50, and 100 spins.
4. Enjoy the Winnings
The features are triggered automatically and you don’t have to enable anything else. Also, the winnings from the Nitropolis slots machine are immediately added to the balance.
Nitropolis Slot Machine Paytable
In order to master how to play the Nitropolis slot machine, you need to get accustomed to the symbols. The main icons are the leaders of the four clans: Dirty Dawgs, Gritty Kitty, Pug Thugs, and Rogue Rats. Other symbols show the clan logos and four card values.
Three or more matching symbols on adjacent reels award a payout. The higher the symbol ranking, and the more symbols in a combo, the bigger the prize. Wild symbols substitute for other icons, and bonus symbols trigger the free spins mode when three or more appear. These are the payouts based on the total bet:

Nitropolis Slots Paylines
The paylines in the Nitropolis slot machine cover all possible combinations of six symbols, going from left to right. On the standard 6×4 grid, this means 4,096 paylines on every spin. However, the Nitro Reels mechanic makes things a bit more complicated.
A Nitro Reel covers two positions but can have up to 12 symbols. And, with multiple Nitro Reels at the same time, you can have up to 85,155,840 paylines on the screen. The total number of ways to win is displayed above the reels on every spin, based on the symbols available.
Nitropolis Slots Bonus Round(s) & Free Spins
The bonus features definitely play a big role in the popularity of the game. There are free spins, free re-spins, and exclusive Nitro Reels with added perks. These make even the Nitropolis free slots online fun and exciting, and you can learn more about the features here:
Nitro Reels
The nitro reels represent the main bonus feature in the Nitropolis slot, as you can probably tell from the names. A nitro reel is a small reel that only takes up two positions on the screen. Inside, it can display between 4 and 12 identical symbols, creating more ways to win.
Furthermore, nitro reels can receive random upgrades that increase the number of symbols displayed inside. Non-winning spins will sometimes trigger free re-spins for another chance to win, known as a second chance.
Winning Respins
When playing Nitropolis slots, every winning round will trigger a free re-spin of the participating symbols. The process repeats until there are no more new winning combinations. All of the payouts from the respins are added to the total and awarded at the end.
Free Spins
The Nitropolis free spins bonus game starts after landing three or more bonus symbols on the screen. Players receive 10, 15, 20, or 25 free spins for 3, 4, 5, or 6 bonus symbols, respectively.
During the free spins, all nitro reels are locked in place for the remaining rounds. Plus, a symbol is randomly selected and turned into a scatter, awarding payouts from any position. The payouts from the free spins are based on the same stake as on the triggering spin.
Nitropolis Slots Gameplay
There is always something happening in the Nitropolis slots machine. The bonus features trigger quite often, the animations are over-the-top, and the music is very intense. All of these elements come together to create an exhilarating gameplay experience.
RTP & Volatility
With an RTP of 96.10%, Nitropolis has a better payout than your average online slots game. It can have good results, especially when combined with extra casino bonuses. In this regard, it is similar to 777 Deluxe slots.
You will require a large bankroll to fully enjoy the game, however, since it has medium-high volatility. This means that wins don’t take place frequently, but the amount can be significant. The hit frequency rate is around 20%.
Software
Who makes Nitropolis slots? The answer is ELK Studios, a reputable software developer that was established in 2013. It has already launched around 60 online slots and continues to expand its offering every few months.
ELK is known for creating eye-catching slots with amusing themes and all sorts of innovative features. Other popular creations include Wild Toro, Electric Sam, and Ecuador Gold.
Graphics & Sound
Nitropolis comes with impressive graphics and a high level of detail. The images are clear and it is easy to distinguish between the different symbols. Players can also admire the city in the background. The main problem is that the animations for winning combos are very limited. Only large wins have special video effects.
The sound effects and the background music go very well with the gameplay. It is a mix of electronic dance music with added Nitropolis sounds, namely big explosions and mechanical sounds as you spin the six reels.
Theme
The theme in Nitropolis is definitely a big selling point. ELK Studios really went all out and invented a whole backstory for the game. It all starts with a short intro when first launching the game. However, most of the lore behind this game is provided in a teaser video released by the developer, and it’s here that the scene is set.
If you’d rather skip the trailer, the story is as follows: Humans are no longer part of the world and only some types of animals are left. These have formed four clans of canines, felines, and rodents who compete for the green gooey nitro required to power their machines. The result is a post-apocalyptic slots theme with steampunk elements.
Our Top Nitropolis Slot Machine Tips
After countless hours playing this game, we have the perfect Nitropolis slots tips. These are easy to follow and can help you have better results and a better time with the spinning reels.
1. Play Free Nitropolis Slots to Practice
Before you start eking into your own bankroll, play the Nitropolis slots free demo to get used to the gameplay mechanics and familiarize yourself with the symbols, etc.
2. Claim Casino Bonuses for Extra Funds
Plenty of online casinos dish out bonuses to new and old players alike. Take advantage of these offers when and wherever you can since they will keep you in the game for longer which, in turn, increases your chance of a big win.
3. Bet Small and Search for the Free Spins
When playing online slots, the temptation is always there to go big and bet half your bankroll on a few spins. Try to avoid doing this. Slots are a simple game of chance, and you’ll risk blowing your entire bankroll in minutes if you go too big. Plus, the longer you’re able to stick around, the greater your chances of success become.
Use the free spins on offer at many of the casinos reviewed on this page to keep you in the game for longer, too.
4. Gamble Responsibly & Have Fun
Never bet more than you can afford. Aim to budget and manage your outgoings to ensure you don’t spoil your own fun.
5. Turn Down the Volume
The music in Nitropolis is interesting but can be slightly jarring and distracting, so we suggest turning it off and focusing on the game.
Playing Free Nitropolis Slots
Given the nitro reels, the free spins, and the re-spinning symbols, the best way to understand Nitropolis is to play it for free. Everything will make sense after a few rounds. Plus, Nitropolis free slots are still really fun to play, even when you don’t put actual money on the line.
You start with a demo balance of $1,000. This way, you can try out different strategies and maybe even use some betting systems. Plus, you can always refresh the page and play free Nitropolis slots for as much as you want to. You never run out of practice credits.
All of the features and mechanics remain the same, so you get the full experience. The eye-catching theme, the sound effects, the music in the background, and the combined bonuses make the game entertaining. Free Nitropolis slots no download are also perfect for a mobile test before betting cash.
Although Nitropolis isn’t available to play at these casinos yet, MyB Casino has a great selection of free slots. You can browse the list on the site and quickly start the ones that catch your eye. The 3D Betsoft slot games here come highly recommended.
Nitropolis Slots App & Mobile Play
It is clear from the buttons and layout that Nitropolis was designed for mobile gaming. The Nitropolis slots app is compatible with all devices and doesn’t require any downloads. Players can start the game directly from the web browser on basically any iPhone or Android smartphone.
The reels adapt to best fit the screen, which can result in symbols of different shapes when switching devices. This isn’t that obvious and doesn’t affect the mobile gaming experience. The upside is that the interface quickly adjusts for portrait and landscape views when rotating the phone.
The controls remain the same as the ones we’ve seen on the desktop version. Plus, the mobile Nitropolis slots app has all of the same features.
