Nitropolis 3 Slot Elk Studios

Nitropolis 3 is an Elk software powered slot with 6 reels and 4096 pay lines that is inspired by the riotous gangs that were chased away by Sergeant Nitro Wolf. Everything is set in the post-nuclear world where animal clans are running the city looking for nitro fuel for their cars. This time, we’re heading towards the tropical beach in search of nitro, and you can join the paws here for fun, or at any of the Elk Casinos for real.

How to Play Nitropolis 3 Slot?

  • By clicking on the Stacked Coins button you will open the separate betting panel which will help you get the bets increased or decreased, or help you choose the betting strategy.
  • Spin button is used to set the reels in motion.
  • Auto will set the reels moving in succession for a chosen number of times.
  • X-iter will activate the X-iter feature and choose the mode.

Slot Features

The dog eat dog lifestyle is not nearly done thanks to Nitropolis 3, and this time, there are a lot of things going on from avalanche mechanics, expanding rows, block symbols, nitro reels and bonus rounds. 


This is your shortcut to the excitement that will allow you to jump straight into the action with one of the 5 game modes that include a higher rate of Super Bonus that gets you into a Super Bonus, Sticky Nitro Reels and Both Ways. Buy Bonus that offers a Bonus game and Sticky Nitro reels. Both Ways Nitro Match offers both of these options. Guaranteed big Nitro Reel, and last but not least is the Bonus Hunt that gives you a boosted bonus chance and more than double chances to trigger the game.

Nitro Reels

Small Nitro Reels will cover 2 symbol positions and contain a number of 1x1 payout symbols. These reels can have 4, 6, 8, 10 or 12 symbols. Big Nitro Reels will cover 6 symbol positions but they contain 2, 3, 4, 5, or 6 symbols that are the size of a 2x2 block. 

Special Symbols

The game comes with 6 special symbols that include a Wild, Redrop, Both Ways, Nitro Match, Nitro Upgrade and Nitro Wild. Wild is subbing in for all the symbols in the game to help form the win combo, except for the Special symbols. With Redrop all the symbols on the grid will respin except for the Bonus symbols and Nitro feature symbols that will remain on the grid. Both Ways symbol will start calculating wins from left to right and right to left.

Nitro Reels happening on the same and adjacent reels as the Nitro Match symbol will match the payout on the adjacent reel with the Nitro Reel. Nitro Reels on the same and adjacent reels as the Nitro Upgrade symbol will upgrade and additional symbols will get added to the Nitro Reels. Hitting Nitro Wild will have all the symbols on the same Nitro Reel and the adjacent reels get replaced by Wild symbols.

Bonus Game

Getting 3, 4, 5 or 6 Bonus symbols on the same spin during the base game will trigger 8, 12, 16 or 20 spins, respectively, and get you into the bonus round. All Nitro Reels in the bonus will be sticky and remain so until the round ends, and there is a chance of retriggering. 

The round has Safety Level that will advance one row for every new free spin initiated that results in a win. Every new Free Spin starts at the current active Safety Level. Landing a combo of Bonus symbols and a Super Bonus symbols will trigger the Super Bonus Game which gets played at 8 rows with Both Ways activated.


Nitropolis 3 merges some of the Elk’s finest features like expanding reels, special symbols, and their favourite X-iter betting options which are getting attached to a majority of their games lately. In terms of the design, it looks somewhat chaotic and all over the place but what it lacks there makes up for in other areas. The gameplay in the sequel is as good as it was in its predecessors. It is highly volatile and will probably hit the books as Elk’s highest paying game to date, with the max win cap of x50000 the bet.

The third installment of Nitropolis is out and recently released and it has a brilliant upgrade and concept. The base game plays so much better, the 2nd one was not bad, but the first release was horrible. I mean close to 1000 spins and I triggered the bonus just to win x32. I would never forget that moment, as that was a good 1 – 2 hours I would never get back in my life wasting it on that slot.

The theme has a funky look and feels to it, almost if you compare it to punk rocker from Nolimit City kinda vibe. Set on the backdrop of an island, the reels fall with stacked, colossal symbols or nitro boosters, that have a lot of stacked symbols inside a window and grow.

The game has a combination of Nitropolis 2 coupled with any of the Gold Series slots. Starting with 4096 ways to pay, and going all the way to 262 122 ways as you continue to win, cascade after cascade. During free spins, you reach new levels of heights that stay in check until the end of the feature.

I like the song as well, Elk designs great music. I mean just play Zulu gold and listen to the African tribe-themed music in the background. Just absolutely amazing.

The game has in-game buy features where you can trigger special effects for a set amount of your total bet. However the main feature is the bonus feature, but the Super Bonus is absolutely awesome.

With both ways to pay, 262 122 ways to pay and 8 free spins are enough to hit a home run and get 50 000x, just make sure you get that dog symbol inside 3 to 4 windows consecutively next to each other starting from the first reel and you will literally break the casino's bank.

I mean you will notice from the previous release, you have a lot of dead spins, but with this release, it plays better and the bonus teases are insane. You will get at least a bonus tease, once every 10 spins, which is unheard of for Elk!

Simply love this game.
