Nitropolis 4 Gameplay

Nitropolis 4 is a 6-reel slot game with a variable number of rows ranging from 4 to 8 and 4096 paylines. The game’s betting range spans from a minimum of €0.2 to a maximum of €100, making it suitable for players with various budgets. The high volatility of the game, coupled with a maximum win potential of 50000x the bet, promises an exciting and rewarding gaming experience.

Visually, Nitropolis 4 boasts a captivating futuristic design, set in a dystopian world filled with towering structures reminiscent of offshore oil rigs. The underwater theme comes to life during the bonus game, where players dive beneath the surface in search of hidden treasures. The game is compatible with various devices, including mobiles, notepads, and desktops, ensuring a seamless and immersive experience for all players.

The game’s symbols are expertly designed to complement the overall theme. Lower-paying symbols include J, Q, K, and A, while medium-paying symbols consist of emblems representing the Rouge Rats, Pug Thugs, Gritty Kitties, and Dirty Dawgs gangs. The game’s higher-paying symbols feature the leaders of the aforementioned gangs, adding a personal touch to the gaming experience. Additionally, the game includes a submarine scatter symbol, a super scatter symbol, a naval mine wild symbol, and big symbols that can reach up to 3×3 in size, all of which contribute to the game’s dynamic and engaging gameplay.

In terms of mechanics, Nitropolis 4 offers a unique Avalanche feature, which is triggered by landing three or more of the same symbol type on adjacent reels, starting from the far left. Furthermore, players can benefit from Nitro Reels and Nitro Multipliers, which can significantly enhance the game’s payouts and overall excitement.

Nitropolis 4 Features

Nitropolis 4 offers a variety of special features that enhance gameplay and increase winning potential.

Wild Symbol

The Wild Symbol substitutes for all symbols except scatters, helping to create more winning combinations.


The Avalanche feature is activated after a win, causing winning symbols to disappear and new ones to fall into their places. Each avalanche adds an extra row, up to a maximum of 8 rows per reel, increasing the number of ways to win. The avalanche continues as long as new wins are created.

Big Symbols

Big Symbols can randomly land during spins, with sizes of 2X2 or 3X3. These can contain low, medium, high paying, and wild symbols.

Nitro Reels

Nitro Reels cover two symbol positions and are loaded with multiple payout symbols. Big Nitro Reels cover 6 symbol positions and can contain super scatter symbols.

Nitro Multiplier

The Nitro Multiplier symbol multiplies all wins in view and can land with values of 4X, 6X, 8X, 10X, or 12X. Multiple Nitro Multipliers can multiply each other.

Nitro Booster

Nitro Boosters add special features to the main reels, such as Both Ways (wins created from left to right and right to left), Garbage Collect (random symbols are removed and the avalanche feature is activated), and Nitro Upgrade (Nitro Reels on the same and adjacent reels are upgraded).

Bonus Game

Landing 3 or more scatter symbols activates the Bonus Game, awarding free spins. Retriggering free spins is possible during the bonus game, and all Nitro Reels that land are sticky during the remaining spins.


The X-iter mode allows players to immediately activate various features, such as Bonus Hunt (increased chance of activating the bonus game) and Super Spin (Max Rows and Both Ways are activated).

These features contribute to the game’s appeal by offering diverse gameplay mechanics and opportunities for big wins. Players can strategize by using the X-iter mode to directly access their preferred features or aim for the Bonus Game to take advantage of sticky Nitro Reels and potential retriggers.

Nitropolis 4 Conclusion

Nitropolis 4, the latest installment from ELK Studios, takes you on an adrenaline-fueled underwater adventure with the nitro gangs. The game’s unique selling points include its expanding reels (from 4 to 8 rows), high volatility, and a whopping maximum win potential of 50,000x your bet.

In my opinion, Nitropolis 4 offers an engaging and thrilling gaming experience. The narratively connected series keeps getting better, and this latest edition is no exception. Compared to other slots in the genre, Nitropolis 4 stands out with its innovative features like Nitro Reels, Nitro Multiplier, and Nitro Booster, which add depth and excitement to the gameplay.

While the RTP has been lowered to 94% from its predecessors, the increased maximum win potential more than compensates for this change. I found myself thoroughly entertained and on the edge of my seat during my time with Nitropolis 4.

I wholeheartedly encourage you to dive into the world of Nitropolis 4 and experience the action-packed gaming adventure first-hand. With its captivating story, unique features, and high win potential, this slot is a must-play for both casual players and seasoned slot enthusiasts alike.
