How Nitropolis 3 works

In the online casino world, there are some providers that have made a name for themselves with just one slot machine, and this is the case with ELK Studios. Even though it deserves to be more in the spotlight for its creations, this provider has made its reputation on a series of slots: Nitropolis. After the success of Nitropolis 1 and Nitropolis 2, it's now the turn of the last one of the family to be released: Nitropolis 3. In this article, we will explain how this slot machine works, and you will see that it is not the easiest to understand.

When you go to this slot, you will always find yourself in a very special world that only the creators of this slot have understood where they were going. The musical atmosphere is still relevant, while the graphics and animations are very good. The starting grid is located on the outskirts of a beach, but the beach seems to be completely polluted as shown by the cans that are located to the right of it.

The starting grid is composed of 6 columns and inside it, up to 8 symbols can fit. However, this grid is evolving with each round of the game, and it can also grow, as you will read in a few lines. The connections work in cascade, that is to say that a game round stops only when it is not possible to make any more connections.

Nitropolis 3 is a slot game that will not bore you at all. There are several features to enjoy during your pay games, while it will be possible to unlock up to two different bonus games.

This is a slot machine that is open to all types of players, as you can bet between €0.20 and €50 per spin. Nitropolis 3 is a free slot machine to try directly at Lucky7Bonus.

As mentioned in the introduction to this slot machine, there are several features that are present during your pay games at Nitropolis 3.

The first feature is called Redrop. As soon as this symbol appears on your screen, all bonus symbols and nitro symbols remain on your screen, while all other symbols are removed from your starting grid.

The Both Ways feature allows you to get paid on both sides of the starting grid, i.e. from left to right, but also from right to left. Without this feature, Nitropolis 3 is a left-to-right slot machine.

Then there are three other features during these paid rounds.

  • The first one is called Nitro Match: each time it appears, the Nitro Reels (we'll tell you about them in a moment) present on the reel and on the adjacent reels become the same symbol.

  • Nitro Upgrade Feature: Nitro Reels on the column and adjacent reels are upgraded to a higher paying symbol.

  • Nitro Wild: All symbols in the Nitro Reels that are in the column and adjacent columns are replaced by wild symbols.

As we explained in the introduction to this slot, Nitropolis 3 works with cascading connections, otherwise known as avalanches. This means that each time a connection is made, the connecting symbol disappears and is replaced by new symbols.

Another feature is the Nitro Reels. In these boxes appear the same symbol. Above these are displayed a number that varies between 4 and 12. This means that if it says 12 and manages to make a connection, it is as if the symbol is present 12 times on your screen. This feature can pay off massively if you manage to connect the same symbol on an entire line. They can appear in 1x1 or 2x2.

As we also explained in the introduction of this slot, the starting grid of Nitropolis 3 is scalable. It can go up to 8 symbols. For this to happen, a Nitro Reels symbol must be at the top of your column, but not appearing completely. If this is the case, then the slot machine will increase so that this symbol is completely present.

In the following example, the dog's Nitro Reels do not appear fully on your starting grid. So, the starting grid will grow to see it completely. By appearing, it increases the number of ways and the possibilities to make connections.

The final feature present during the pay games at Nitropolis 3 is with the big symbols. These can appear in : 2x2, 3x3 and 4x4.

The different symbols of Nitropolis 3

Nitropolis 3 is a slot machine that has 13 different symbols, in addition to the ones we have just seen. First of all, we'll look at the wild symbol. This symbol is present in this slot and allows you to connect with all the other symbols in the slot, except for the bonus symbols, super bonus, Nitro, Redrop and Both Ways. The wild symbol has no value in itself, but just takes on the value of the symbol it connects with.

Then there are two categories of symbols: premium symbols and non premium symbols. First of all, we will talk about the premium symbols, which number 8. They are called so because they appear much less frequently than the other symbols. However, as soon as they are part of a connection, they pay you much more.

They are represented by different logos and animals. In the following screen the values of each connection are displayed for a starting bet of 1 euro.

In addition to these 8 premium symbols there are 4 non-premium symbols. As you can imagine, these are called so because they have a much higher frequency of appearance. On the other hand, as soon as they become part of a connection, they tend to pay you much less. These symbols are represented by the strongest values in a deck of cards, namely: Ace, King, Queen and Jack.

The following screen shows the values of each connection for a starting bet of 1 euro.

The different connections of Nitropolis 3

Connections on the Nitropolis 3 slot machine work in cascade, as we've written about many times in this article. For a connection to occur, the same symbol must appear at least once in your first three columns, regardless of where it is located.

The further a symbol goes on your starting grid, the bigger your final win will be. It is important to know that the number of ways increases with the height of your starting grid, but also with the number of symbols that make up the grid.

The connections work from left to right, but if you manage to get a feature in the base game, they can also work from right to left.

How the Nitropolis 3 bonus works

As we have seen in the introduction of this slot, Nitropolis 3 is a slot that has 2 different bonuses. First of all, you have the normal bonus, which you get with 3 bonus symbols appearing on the same game spin. The more symbols that appear, the more free spins you get:

  • 3 bonus symbols = 8 free spins

  • 4 bonus symbols = 12 free spins

  • 5 bonus symbols = 16 free spins

  • 6 bonus symbols = 20 free spins

During these free spins, the starting grid starts out 6 x 4, just like in your base game. All the features present in the base game are also present during these free spins. Just like the base game, the starting grid is also scalable.

Each time the starting grid grows, it does not revert back to the base grid. If the starting grid grows and a connection is made on the lap where the grid grows, then you will be entitled to a safety level. This level increases by 1 each time the grid grows and a connection is made.

So, as soon as the round is over, the security level allows you to have a machine with 5 symbols, then 6, then 7 and 8 on each column, if you manage to make connections.

It is also possible to get a Super Bonus on this slot. To do so, you must have at least three times the Super Bonus symbol on a single spin. Once this is the case, the free games are launched.

This great bonus can massively pay you, since all the features are present: the both ways, the starting grid at a maximum height, etc.

Just like the previous bonus rounds, you will be able to get additional free spins. To do this, you must get at least three times the bonus or super bonus symbol, depending on which one you are in.

For those who wish, it will be possible for you to buy the free games on this slot machine. Thus, to get the least volatile bonus, you will have to pay 100 times your starting bet.

If you want to experience the thrill and get the super bonus, you will have to pay 500 times your starting bet. You will also be able to buy some features, as you can see in the following screen.
