Nitropolis 4 Review
ELK Studios’s Nitropolis series has become one of the company’s flagship brands and for good reason. Each title has managed to take what fans loved about the previous one and build on it, and Nitropolis 4 may be the culmination of all of that work. The slot transports you to the franchise’s dystopian world and, this time, provides you with the chance to land wins of up to 50,000x your stake. Let’s find out what else it has to offer in this Nitropolis 4 slot review.
Nitropolis 4
Nitropolis 4 RTP and Wagering
Nitropolis 4 serves up some explosive action in the base game. The slot uses six reels with four rows to begin with, with 4,096 ways to win. These can expand, but the game does not provide a number for how many ways can become available. Rest assured, it is a lot.
The betting range is fairly standard, with the lowest bet being €0.20 and the maximum being €100. The Nitropolis 4 RTP is a little disappointing at 94%. However, the slot game makes up for this with a colossal 50,000x your stake maximum win. Like all titles in the series, the game is considered highly volatile.

Nitropolis 4 Symbols and Audio & Video Design
The weird and wonderful world of the Nitropolis franchise takes us into some sort of factory for its fourth instalment. The slot has the typical humour and wackiness that has come to define the series, with some brilliant animations and plenty of colour helping to bring it all to life.
The four animals that occupy the world make up the highest-paying symbols, with the dog paying out 3x for a combination of six, followed by the cat, pug, and mouse, paying out 2x, 1.5x, and 1.25x, respectively. The lower-paying symbols are made up of each animals logos and the standard card symbols.

Nitropolis 4 Bonus Features
The Nitropolis series is famous for its big selection of features. Let’s see what Nitropilis 4 bonus features are on offer.
Avalanche Mechanic
Whenever you land a win, all symbols involved are removed, and new ones fall into their place. In addition, the symbols expand upwards by one row. This continues happening until no new wins can be formed.
Nitro Reels
These can land on any spin and take up two positions on a reel. They are mini-reels and will spin on their own. They can contain up to 12 payout symbols. Big Nitro Reels can also land, taking up six positions and having 2x2 payout symbols.
Nitro Multipliers
There are also Nitro Multipliers that can land on any spin. These cover two positions and display a multiplier of up to 12x. These will then be applied to any wins on the board.
Nitro Boosters
These are hugely important modifiers that can land on the Nitro Boost reel above the game grid. They can land on any spin and include:
- Redrop: All symbols except Bonus symbols, Wild Symbols, Nitro Mulipliers and Nitro Reels are replaced, with new wins being calculated.
- Both Ways: The game will pay wins both ways.
- Garbage Collect: Random symbols are removed, and an Avalanche is triggered.
- Max Rows: The grid expands to 6x8 in size.
- Nitro Appear: A random Nitro Reel is added to the grid.
- Nitro Upgrade: This upgrades a Nitro symbol in view.
- Nitro Wild: A Nitro reel is filled with Wilds and placed on the grid.
- Nitro Match: A Nitro Reel and a random symbol make a winning combination. If there are no Nitro Reels on the grid, this is held until one lands.
Free Spins
The Nitropolis 4 Free Spins round is triggered when you land three or more Scatters. Three, four, five, or six Scatters launched eight, 12, 16, or 20 spins, respectively. During the round, Nitro Reels are sticky, and the safety row of the reels increases by one on each winning spin. There is also a Super Free Spins bonus, where the grid is locked at maximum size, and both ways win on each spin.
Nitropolis 4 Final Thoughts
Nitropolis 4 is another fantastic entry into the Nitropolis series. The 50,000x maximum win is a huge selling point, while the bonus selection is also fantastic. The bonuses all complement each other nicely, with the potential for some hugely volatile and exciting gameplay sequences. The RTP is a little bit of a letdown at 94%, but outside of this, there is very little to fault with Nitropolis 4.
Rating: 8.5
