Nitropolis 4 from ELK Studios plunges players into a post-apocalyptic setting where animal gangs battle for scarce resources. This latest chapter, released in 2023, takes place on an industrial oil rig in the ocean, carrying on the series’ tradition of using different environments.

Each game in the series transports players to a different setting that depicts the ongoing struggle for survival among these factions. Nitropolis 4’s visuals are sharp and detailed, with a color scheme of dark blues and grays accented by neon game symbols.

This installment features familiar faces such as the Dirty Dawgs, Pug Thugs, Gritty Kitties, and Rouge Rats, and each gang’s symbols are on display. High-value symbols, representing the gang leaders, are drawn with care and add depth to the gameplay.

The soundtrack combines electronic and industrial sounds to provide a tense and engaging backdrop for the action. A deep voice narrates the events as they happen, and the sound effects complement the game’s features and big wins.

That being said, Nitropolis 4 really holds up the impressive legacy of its predecessors. What stood out to us the most was the attention to detail in both the theme and design. It’s clear that ELK Studios has created another captivating title in the Nitropolis series.

In the Nitropolis 4 slot, players can adjust their bets to suit their style and budget. The minimum bet starts at $0.20. On the other end, high rollers can increase their stakes up to a maximum of $50 per spin. This range is adequate, and while not the largest, it ensures that both casual and serious gamblers can find their comfort zone.

The standard grid setup in Nitropolis 4 is 6×4, but it doesn’t stop there. With each win, players might see the grid expand vertically up to 8 rows, due to the game’s features. The game kicks off with 4,096 ways to win, but thanks to the Nitro Reels feature and the expanding grid, the number of possible win ways can skyrocket into the millions, typical for ELK Studios games.?

Nitropolis 4 is a high-volatility slot, meaning that wins might not come as frequently. The RTP is set at 94%, which is slightly below the industry average. This may be a disadvantage for some, but the maximum payout of 50,000 times your bet may entice you to stay, so try the Nitropolis 4 demo first.

When you’re ready to start playing Nitropolis 4, simply tap the glowing arrow button in the lower right corner to begin spinning. If you prefer to sit back and watch the action unfold, the autoplay feature on the right lets you choose between 10 and 100 spins.

For those curious about the nuts and bolts of the game, the menu icon (three horizontal lines) opens up a wealth of information. Here, you can check out the paytable, the bonus features, adjust settings via the gear icon, and see the latest promotions related to the game.

In terms of winning, you’ll need to line up 3 to 6 matching symbols from left to right. The naval mine, which acts as the Wild symbol, can substitute for any pay symbol to help forge or boost winning combinations. It’s as valuable as the highest-paying Doberman symbol when you hit a line of Wilds alone.

Here’s a more detailed look at the paytable for Nitropolis 4:

• Doberman symbol: Pays 3x for 6, 2.5x for 5, 2x for 4, and 1.5x for 3.
• Cat symbol: Pays 2x for 6, 1.5x for 5, 1.25x for 4, and 1x for 3.
• Pug symbol: Pays 1.5x for 6, 1.25x for 5, 1x for 4, and 0.75x for 3.
• Rat symbol: Pays 1.25x for 6, 1x for 5, 0.75x for 4, and 0.5x for 3.
• Gang symbols (Dirty Dawgs, Gritty Kitty): Pay 1x for 6, 0.5x for 5, 0.3x for 4, and 0.2x for 3.
• Other gang symbols (Pug Thugs, Rogue Rats): Pay 0.8x for 6, 0.4x for 5, 0.25x for 4, and 0.15x for 3.
• Low-value symbols (A, K, Q, J): Pay 0.3x for 6, 0.2x for 5, 0.15x for 4, and 0.1x for 3.

Given the game’s high volatility, wins might not be frequent, but they are often worth the wait. It can take a bit to get used to all these elements, but as you play, the excitement and potential rewards can really draw you in. Stay tuned as we uncover even more about the game’s features in the upcoming section.

The Nitropolis 4 slot is stacked with a variety of features that might take a moment to grasp, but once you do, they showcase the typical flair we’ve come to expect from ELK Studios. Here’s a walkthrough of these elements.

Wilds and Scatters

The game uses a naval mine as the wild symbol, which can substitute for any other symbol to help create winning combinations. The only exception is the scatter symbol, depicted by a submarine, which unlocks the door to the game’s bonus rounds.

Avalanche Feature

This feature activates after every win. Winning symbols vanish, making room for new ones to tumble down, and with each cascade, the game potentially adds an extra row to the reels, expanding them from a 6×4 grid to up to 8 rows.

Nitro Features

Let’s go over the basics of Nitro features:

• Nitro reels: Occupying either two or six spaces on the reels, these reels come loaded with multiple symbols.
• Nitro multiplier: These powerful multipliers can boost your winnings significantly, offering multipliers from 4x up to an impressive 12x. If you land more than one, their values combine for even larger payouts.
• Nitro booster: Keep an eye on the two screens above the reels where one of eight possible game-enhancing modifiers can appear. These modifiers range from locking valuable symbols in place to converting entire reels into wilds.

Free Spins and Super Bonus Rounds

The excitement builds when you land three or more submarine scatters, which activates the free spins feature. You’ll be given between 8 and 20 free spins, during which Nitro Reels become sticky for increased win potential. If you land a Super Scatter during the round, you will be able to access the Nitropolis 4 Super Bonus Game, which will activate features such as Both Ways Pay and Max Rows right away.

X-iter Mode

For players who want to get right into the action, the X-iter mode provides a shortcut to the game’s special features. This mode allows you to buy your way into various game scenarios, ranging from an increased chance of triggering bonus rounds to immediate access to the Super Bonus Game.
