Nitropolis 4 Slot

Following the animal-run dystopian world setting of the Nitropolis series, ELK Studios released Nitropolis 4 in 2023 as a continuation of the renowned series. Following the same story as before, the characters here are running a massive industrial oil rig, with the setting changing from above the water to way down below it in the bonus features. Nitropolis 4 has a huge number of gameplay features and dynamic bonuses with some amazing animations and graphics, setting it apart from other online slots. There is no wonder why the Nitropolis series has remained so popular. 

Nitropolis 4 Game Background

Being the fourth addition to the series, the Nitropolis franchise is widely popular throughout the online slot community. Nitropolis follows the journey of animated animals through a dystopian world, with the first couple of iterations taking place in different locations, like the last game taking place on a tropical beach setting. Nitropolis 4 is set aboard a huge oil rig, which is quite a niche location for an online slot scene. The game offers 4096 different paylines yet is not part of the Megaways slot games franchise despite the number of different paylines being higher than in more other slots. The game has an abundance of features to look at, but first, we will have a look at the visuals and the playgrid in Nitropolis 4.

The playgrid in Nitropolis 4 is based on a 6-4 layout, which can go up to 6-8 if a nitro reel symbol appears. Set inside an oil rig, the grid is placed inside a control room, with computers and switches displayed on both sides of the grid. The symbols are locked into the grid by industrial metal beams. The top of the playgrid is a mechanical device that can shunt upwards when needed to create more space. The playgrid also drops below sea level when certain bonuses are activated, making this one of the most dynamic playgrids seen by ELK Studios.

Nitropolis 4 Bonus Features

To start with, there are base game bonus features in Nitropolis 4, like the drops; these allow all nitro reels, multipliers, wild symbols and bonus symbols to stay in play with other symbols being removed. The other main feature is the pays both ways mechanic allows matched combinations to come into play from both the left and the right-hand side of the screen.

Some of the more simple features in Nitropolis 4 are the wild symbols included in a number of releases, from slot games to Slingo titles, with the ability to substitute for base game symbols. There is also an avalanche mechanic, meaning when matching combinations are made, they will disappear, leaving space for more symbols to drop into the gap. 

Now, into the Nitro Boosters, there is a grand total of 8 different nitro boosters, all functioning in 

different ways:

• Max Rows- Expands the playgrid to 8 rows in size.

• Garbage Collect - A randomly selected symbol is removed.

• Nitro Appear - A nitro reel of any size is placed, replacing existing symbols.

• Nitro Wild - A nitro reel is filled with wild symbols.

• Nitro Upgrade - A nitro reel is upgraded with additional symbols added.

• Nitro Match - A nitro reel is matched with a symbol in view, and the nitro reel is filled with that symbol.

• Nitro Reels- These reels cover 2 symbol spots and contain either 4,6,8,10, or 12 symbols.

• Nitro Multiplier - These cover 2 symbol positions and multiply all prizes in view.

If that is not enough, Nitropolis 4 also offers a free spins bonus after acquiring 3 bonus symbols, similar to scatter symbols. This feature provides free spins to play through with the bet stake of the triggering spin being used throughout.
