How Nitropolis works

Nitropolis is a slot developed and published by the fast-growing online gaming provider ELK, which could do with more exposure. This slot was released in November 2020 and is available at many online casinos. The theme of this slot takes us to a post-apocalyptic world where wild creatures rule. It's up to you to stop these clans from getting their hands (or rather paws) on the precious green liquid called Nitro, which can rule the world or even destroy it! The Nitropolis slot has an original format, with 6 reels containing a minimum of 4 symbols. The objective of this slot is to make connections of identical symbols to win. There are no predefined paylines on Nitropolis, the connections are adjacent. On each winning spin, the symbols that connected are cleared to make room for other symbols: this is the Winning Respins feature.

Nitropolis contains many original features. To begin with, there is a wild symbol, represented by an explosion. This symbol replaces any symbol and will be a valuable aid in making connections.

This slot also contains a feature called Nitro Reels. This feature appears randomly and allows the same symbol to take up two slots on a reel and multiply. This allows up to 12 symbols to be held in just two slots, greatly increasing the ways and the wins. The number of symbols in the Nitro Reels can be increased by a random re-spin using the Second Chance Respin feature, or between free spins.

Nitropolis' different symbols

There are 12 symbols in Nitropolis that must be connected to win. The value of these symbols varies according to their rarity. The symbols that appear most often are called classic symbols. They are represented by the highest values in a pack of cards, namely Jack, Queen, King and Ace. These are the symbols that pay the least.

Nitropolis contains symbols with an intermediate value. They are represented by the clans of the different creatures in this slot, including:

  • Rogue Rats ;

  • Pug Thugs ;

  • Gritty Kitties;

  • Dirty Dawgs.

Nitropolis also has symbols that have a much higher value but are more difficult to connect to: they are called premium symbols. These are represented by the creatures in Nitropolis, which appear on a blue, green, purple and red background.

The following image shows the payout range for each symbol in the Nitropolis slot machine (€1 bet).

The different connections of Nitropolis

One of the main qualities of Nitropolis is the large number of ways offered. Indeed, there are no predefined paylines in this slot. Here, the connections are adjacent, which means that the mere presence of at least one symbol on the first three reels is enough to win, the location of the symbols within the reel not being important. Thanks to this principle of adjacent connections, Nitropolis offers at the beginning of each spin 4,096 ways which are read only from left to right.

This number can be increased in an almost unlimited way with the Nitro Reels function. In fact, by increasing the number of symbols, the number of paylines can be increased to 85,155,840 ways per spin!

Nitropolis Bonus Feature

Like many slots, Nitropolis offers its users access to a bonus feature in which free spins are awarded. In order to get these free spins, a minimum of 3 scatter symbols, represented by a futuristic car, must appear on the same game round. The number of free spins varies according to the number of scatters obtained:

  • 3 scatters = 10 free spins ;

  • 4 scatters = 15 free spins;

  • 5 scatters = 20 free spins;

  • 6 scatters = 25 free spins.

You have the possibility to collect free spins during the bonus by following the same pattern as listed above.

The Nitropolis bonus will award you with a random symbol that will be your reference symbol throughout the bonus. You will win as soon as this symbol appears on three different reels, regardless of which reels are involved.

Another interesting feature is that the Nitro Reels are sticky, which means that they will stay in the same place throughout the bonus and can increase in size, allowing you to make big wins if you connect.
