Nitropolis 4 Free Play

Nitropolis 4 slot makes our favourite characters return to drill for more Nitro, and things get crazier than ever before. It picks up right after Nitropolis 3 and introduces some new Nitro Boosters to make it even more exciting. Nitropolis 3 is already an extraordinary game, so ELK Studios doesn't have to work too hard to appeal to the players in this upgraded version of that game.

To be honest, this game isn't that different, and that is a great thing. It would not be very smart to try and experiment too much when they can easily introduce a few new bonuses and improve the game slightly to have another really successful game. Even the characters featured in the Nitropolis series are getting their own games, like Gritty Kitty of Nitropolis. This is easily one of the most popular series by ELK Studios, so they will keep releasing new games for a long time.

This game can be a bit complicated, so stay tuned for a detailed explanation in this Nitropolis 4 slot review.

Theme & Design: Dystopian Animal Gangs

Theme and Design

Nitropolis 4 drops you right into the thick of a gritty, post-apocalyptic world cooked up by ELK Studios. Picture a bustling dystopian city where animal gangs are duking it out for the top spot. You've got your Rogue Rats, Gritty Kitties, and Pug Thugs; all brought to life with detailed symbols that really pop against the dark, industrial backdrop. It's like flipping through a graphic novel. The design is packed with detail and character, making for a proper immersive experience.

Music and Soundtrack

The soundtrack's a perfect fit for the theme. You've got intense beats and industrial sounds thumping away with each spin. During my test run, I was particularly impressed by the sound effects.

Bonus Features Explained in Nitropolis 4 by ELK Studios

This game will surprise you with one extraordinary bonus after the other. Let us explore what it offers exactly:

Avalanche Feature

All symbols that participate in wins explode. The remaining symbols and new symbols drop to fill the reels once again. Also, an additional row is added (max 8 rows), and this bonus continues until you stop landing wins. Nitro Reels and Multipliers remain on the reels and Respin during the refill.

Nitro Reels

This reel covers two symbol positions and can have 4 to 12 identical 1x1 payout symbols. A big Nitro Reel covers six positions and can have up to 6 identical 2x2 payout symbols. It can also have a Super Bonus symbol, but that will only count as 1 symbol.

Big Symbols

Wilds and regular symbols can appear as 2x2 or 3x3 symbols, and they always count as the number of 1x1 symbol positions they occupy. Any empty spaces below big symbols or Nitro Reels are filled with matching 1x1 symbols.

Nitro Multiplier

Nitro Multiplier can appear inside a Nitro Reel with values from 4x to 12x. It will multiply any wins that occur and also multiply with other Nitro Multipliers.

Nitro Booster

The Nitro Booster has two screens that can award features before the reels stop. Here are the boosters you can enjoy:

• Redrop Feature: When the wins dry up, the Redrop Feature jumps in. Symbols like Wilds and Nitro Multipliers stay put, while Nitro Reels Respin and new symbols drop in, giving you another shot at a win.
• Both Ways Feature: This one pops up randomly in the base game or during special features. When it's active, you can win from both left-to-right and right-to-left, starting from reels one and six.
• Max Rows Feature: This expands your reel set to its full eight-row glory, either temporarily in the base game or permanently in certain special features like the Super Bonus Game.
• Garbage Collect Feature: This quirky feature randomly picks a symbol type and bins all instances of it before dropping in new symbols. It can shake things up nicely and create new winning opportunities.
• Nitro Appear Feature: Sometimes, a random Nitro Reel or a big Nitro Reel will pop up in empty spots, replacing old ones.
• Nitro Wild Feature: This clever feature turns an existing Nitro Reel into a full stack of Wilds, if any are on the board. If there aren't any, it'll hold onto it until one Nitro Reel appears or the round ends.
• Nitro Upgrade Feature: An existing Nitro Reel might get upgraded by adding extra payout symbols or boosting its Multiplier value.
• Nitro Match Feature: After the main reels stop but before payouts are awarded, this feature kicks in. It aligns similar symbols in adjacent Nitro Reels, ensuring a steady stream of wins and keeping the action flowing.

Free Spins Bonus Game

Land three or more bonus symbols in this game, and you can trigger Free Spins as follows:

• 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 spins, all Nitro Reels stick around, boosting your chances of big wins. 3 or more Scatters during this bonus will get you even more Free Spins. During Free Spins, every winning spin bumps up your safety level by one row. Think of it as a floor, as each new spin starts from this level, keeping your previously won heights up to eight rows.

Super Bonus Game

If you land a mix of regular bonus symbols and a Super Bonus symbol, you're in for a wild ride. The Super Bonus Game kicks off with Max Rows and Both Ways features already active. That means all eight rows are in play, and wins can form from both left to right and right to left.

X-iter Feature

The X-iter feature allows you to buy the following:

• Bonus Hunt: For 2x your bet, you can double your chances of triggering Free Spins.
• Nitro Booster: For 10x your stake, you get a spin with 2 guaranteed Nitro Booster features.
• Super Spin: For 25x your bet, you can enjoy a spin with Max Rows and Both Ways active.
• Bonus: You can buy the Bonus Game by paying 100x your bet.
• Super Bonus: Buying the Super Bonus will set you back by 500x your bet.

Win 50,000x Your bet in the Nitropolis 4 Slot Machine!

Nitropolis 4 offers a stonking Max Win of up to 50,000x your bet. The RTP sits at 94%, and it's a high-volatility game, so brace yourself for a wild ride. Remember, with high volatility, wins might not come often, but when they do, they can be hefty. The hit frequency of this game is 18.10%, which is on the lower side, so you have to be patient.

Verdict for Nitropolis 4 Video Slot

Nitropolis 4 by ELK Studios is a beast of an online slot game that can be very addictive and fun. You get a few new additions that weren't there in Nitropolis 3, including the Max Rows, Nitro Appear, and Garbage Collect features. A very important addition is the Nitro Multiplier, and it can do a lot of damage. Other than these changes, not much has changed, and those who have enjoyed Nitropolis 3 can't help but enjoy this one too.

The bonuses that you want to chase are the Bonus Game and the Super Bonus Game because they come with extra benefits like Sticky Nitro Reels, Max Rows, and Both Ways Active. When it comes to the bonuses, I can't complain at all. This game is the result of years of hard work because it builds on its predecessors, and I have no doubt you will enjoy it. I would have given it a 10 out of 10 rating if the RTP was 96% or higher. Still, playing this game is definitely worth it.
