Nitropolis 4 - Review, Demo Play, Payout, Free Spins & Bonuses

Nitropolis 4 Slot Review

Welcome to the freak show! Nitropolis 4 online slot continues where its predecessor Nitropolis 3 stopped and keeps the flame alive. ELK Studios is again inviting you to think about what the future will be like, with no humans around and animals taking control of literally everything. From dangerous Dobermanns to sneaky cats and resourceful rats, they have all found a spot on an oil platform ready to explode.

Theme and Graphics

The dystopian Nitropolis is once again taking centre stage! Designers have created an animal-themed slot that follows the distinctive style and vibe of previous episodes. The resemblance is most obvious when compared to the original Nitropolis. However, we must admit that Nitropolis 4 looks far more fresher and a lot more modern.

The Rogue Rats, the Pug Thugs, the Gritty Kitties and the Dirty Dawgs are back, and there are no new characters to mess up the already-established rankings among the animal gangs. The continuity is admirable, and overall, Nitropolis 4 slot is a great-looking game, as long as you don’t mind edgy soundtracks and even edgier characters with strong personalities.

Nitropolis 4 Slot RTP and Variance

Nitropolis 4 has an RTP of 94%. Unfortunately, it is well below what we consider to be fair and acceptable in online slots. The game offers high volatility and pays less often than average, but once it does, the prize will be notable. It is worth the effort as the maximum win is capped at 50,000x the stake.

How to Play

Here we have a quick guide on how to play ELK Studios’ Nitropolis 4 demo slot and real money game:

• The big spin button that starts the reels
• Use the coin icon to finetune your bet total
• Open the main menu to access rules, paytable, and bonus features, as well as Quickplay option
• Press the Autoplay button for auto-spins
  • Choose between 10, 25, 50, and 100 auto-spins

How to Win

Open the Nitropolis 4 slot, and you’ll see that it starts on a 6x4 matrix with 4,096 ways to win. As soon as you hit that first win, you’ll notice a fun twist to the old-fashioned grid. Wins trigger the cascading mechanic that removes all the winning symbols with a bang, so new symbols may drop.

On top of that, the gaming grid expands up to 8 rows in height. As the board expands, the number of paylines can increase up to 737,280!

The best-paying symbols in Nitropolis 4 casino game are animals, led by the Dobermann, that will pay you up to 3x the bet. Royals bring the least amount to the bankroll, only up to 0.3x your stake.

Free Spins and Bonuses

Nitropolis games are famous for being stacked with features, and Nitropolis 4 is no different. Players should buckle up and get ready for a wagonload of bonus games and special elements that make every new spin different from the previous one.

Expect to find the immensely popular X-iter option, as well as free spins, multipliers, Nitro Reels, and big symbols. Here they are with a few explanations:

Free Spins

The Free Spins bonus game is triggered with the help of a submarine (Bonus symbol):

• 3 symbols in view - 8 free spins
• 4 symbols in view - 12 free spins
• 5 symbols in view - 12 free spins
• 6 symbols in view - 20 free spins

During the Nitropolis 4 bonus feature, Nitro Reels are sticky. If you trigger the feature with at least one Super Bonus symbol, you get to play the Super Bonus Game with the maximum number of rows and paylines that work both ways.

Nitro Booster

On top of the playing board, you will notice two displays reserved for Nitro Boosters. The Nitropolis 4 slot has eight Nitro Boosters in total:

• Redrop - Bonus and Nitro symbols are sticky, while other symbols are removed and replaced.
• Both Ways - wins are paid both ways.
• Garbage Collect - removes random symbols, causing a cascade.
• Max Rows - the grid expands to 8 rows high.
• Nitro Appear - a Nitro Reel is placed on the grid and the size is set randomly.
• Nitro Wild - active Nitro Reel is filled with Wilds.
• Nitro Upgrade - Nitro Reels increase in value.
• Nitro Match - Nitro Reel is matched with another symbol to create a winning combo.

Nitro Multiplier

Nitro Multipliers cover two positions but count as only one symbol. They multiply all wins in the view. The values of multipliers are:

• x4
• x6
• x8
• x10
• x12

When more than one multiplier is present on the Nitropolis 4 playing board, their values multiply.

Nitropolis 4 Review – Our Verdict

Elk Studios hit a goldmine with the Nitropolis series and, surprisingly, was able to keep it fresh for so long. Having four somewhat similar titles would, in many cases, be repetitive, but not when it comes to Nitropolis 4 and its predecessors.

It’s the Same Vibe with Many Features

Nitropolis 4 is not exactly a game full of surprises. The characters and the setting will feel familiar, and even a few features will evoke memories of your past sessions on Nitropolis 3 and Nitropolis 2. Still, the creative forces at ELK achieved creating a game that doesn’t feel or look stale but is very much on the contrary.

The RTP of 94% will, for plenty of players, feel like an abomination, and rightfully so. In a world where everything under 96% is considered unfair, it is surprising to see a supplier deciding to go with it and not increase the numbers. It is a significant drop from 95%, the RTP attached to the previous two games, and an even bigger plunge from the original that boasted an RTP of 96.1%. In this one aspect, Nitropolis 4 took a turn for the worse.

Nitropolis 4 - Is It Worth a Spin?

Players who can tolerate the low RTP and high volatility will be satisfied with all the tricks Nitropolis 4 is hiding up its sleeves. After all, the massive maximum payout of 50,000x the stake should not be neglected without a second thought. It is promising, but the road to it could be long and covered with more empty spins than a casual gamer can tolerate.
