Over the past decades, the post-apocalyptic genre has been invariably popular in modern culture. The likelihood of a global catastrophe capable of engulfing the entire planet does not seem so incredible. Many people wonder what our world could be like after a nuclear war or a pandemic of gigantic proportions.
With this in mind, Elk Studio has released the Nitropolis slot machine, which tells about a fantasy world ruled by clans of animals: dogs, cats and rats. And the maximum value for them is the nitro fuel with which they fill their cars.
This free slot machine brings a new dimension to the Science Fiction theme, to which, apart from Kaiju Video Slot, Elk Studios have added the next version of this slot game, Nitropolis 2.
Nitropolis is a video slot with six reels and four rows of symbols on the main screen. There are no active lines. You can bet from twenty cents to one hundred euros per spin. It is believed that there is always one hundred coins at stake.
Initially, there are 4096 winning combinations in the Nitropolis slot machine, but thanks to the Nitro Reels function, their number increases and can reach 85,155,840!
Paylines are made up of four to six identical symbols. The arrangement of the elements in the columns does not matter. The main thing is that they are in different adjacent columns, starting with the first one. Several such variations are allowed in one spin.
Each combination has its own coefficient by which payments are calculated. The second parameter is the current value of the coins. There is no doubling game. All winning sequences launch Winning Respins.
Nitropolis is a pretty creepy place. Ugly metal towers, tangled wires and tall fences are visible behind the reels. All this resembles the territory of abandoned factories. However, one should not expect beautiful cityscapes in a post-apocalyptic world.
Four gangs rule in the world of the Nitropolis slot machine:
The Dirty Dawgs
The Gritty Kitties
The Pug Thugs
The Rouge Rats.
Representatives and logos of these clans are depicted on the reels of the video slot. Also drawn are the multi-colored letters J, Q, K and A. The same symbols can appear in the form of stacks.
In the dynamic payout table, the amounts are indicated not in coefficients, but in credits according to the current rate.
Nitro Reels is a section on a reel that spans two cells. It is highlighted with a green frame with a small board on which a number from four to twelve appears. It indicates how many identical pictures are contained in this zone. All of them are considered as separate elements of paid combinations. The scatter can also be dropped in Nitro Reels, but it counts as one symbol.
Nitro Reels can appear on all reels at once, but also at the end of the spin they may not be on the field at all.
As for about other prize options:
Winning Respins - If a combination is formed, the player receives a payout first. Then the free respin begins, during which only the icons from the paid chains are changed to new ones. If Nitro Reels are involved in the formation of the sequence, they also rotate. Respins last as long as they bring payouts.
Upgrade - In any spin, the Nitro Reel can increase the number of symbols it contains. In this case, there are also more potential combinations.
Second Chance Respin - If a spin does not pay off, the Nitro Reel may re-spin to give you a chance to win.
Free spins are subject to special conditions.
Free Spins - Three, four, five or six scatters trigger ten, fifteen, twenty or twenty five spins, respectively. In them, you will not risk your money. The online casino will place the bet for you.
Free spins are extended with a minimum of three scatters.
You cannot win a cumulative jackpot at Nitropolis, but any spin can bring in a very large sum. The maximum payout in one round is one million coins!

RTP: 96.1%,
Volatility: medium-high,
Win rate: 19.8%.
The theoretical payback rate is not very high, but within the normal range. The mathematical superiority of the casino is 3.9%.
The degree of variability is pretty impressive. On average, approximately one in five spins brings a payout or triggers a bonus feature.
The developer has also released a mobile version of the Nitropolis slot machine. It is intended for users who prefer the online casino format on smartphones and opens in browsers. There is no need to install separate applications on the device.
In the Nitropolis mobile slot, the rules are identical to those in the desktop version. The interface is pretty much the same. Settings, rules section, paytable, automatic mode, betting systems and other features are available.
On the official website of Elk Studios, the online slot Nitropolis is called a "chaotic slot". This is a very accurate description. At first you may think the game has too many complex rules and there may be a feeling of chaos, but it quickly passes. Once you understand all the nuances, you can safely enjoy the truly addicting gameplay.
The interesting theme and colorful characters, unique Nitro Reels feature and other bonus features all contribute to making this slot an instant favorite among slot players!
If you want to try out the slot without risk, then you can play for free by starting the demo game mode on this page.
