Nitropolis Slot Series – The Complete Guide

With players now more familiar with the gameplay of the slot, Elk Studios cranked up the action in its sequel. Nitropolis 2 takes the wild, post-apocalyptic chaos of the original and makes it even bigger and better. The Nitro Reels and Winning Respins are back, but the new Nitro Booster feature steals the show. With eight unique reel modifiers like Both Ways, All Wild, and Nitro Upgrade, it makes every spin feel fresh and full of possibilities.

Free Spins return with locked Nitro Reels, amping up the potential for massive wins. With an eye-popping 191,102,976 ways to win, Nitropolis 2 delivers more action and excitement than ever before. It’s still a high-volatility game, so patience is key, but fans of the original will love the enhanced gameplay, creative design, and non-stop thrills of the sequel.

Nitropolis 3 takes the series in an exciting new direction, addressing frustrations from previous games while ramping up the fun. This time, the Nitro Gangs flee to a toxic beach, bringing a fresh theme with hazy visuals and Elk Studios’ signature funky soundtrack.

New features like the Avalanche slot mechanic, where wins expand the reels up to eight rows, and Big Symbols (up to 4×4), add dynamic gameplay. Returning favorites, including Nitro Reels and Both Ways payouts, blend seamlessly with innovations like the Redrop Feature and enhanced Nitro mechanics like Nitro Match and Nitro Upgrade.

Most notably, the game boasts a massive win potential of 50,000x, the highest in the series. Nitropolis 3 delivers a smoother, more polished experience, reigniting the thrill for fans.

Nitropolis 4 picks up where things left off, in a post-apocalyptic world with an animal gang ruling the reels. Set in an equally gritty 6×4 reel grid, the game introduces tumbling reels, where winning symbols are replaced by new ones, offering more chances to win from a single spin.

New to Nitropolis 4 is the Nitro Booster, featuring eight modifiers like Max Rows, Nitro Wilds, and Redrop, adding unpredictability and excitement. The Free Spins round returns with sticky Nitro Reels that grow with each win, and a Super slots Bonus variant which expands the grid and activates Both Ways payouts from the start.

With a massive 50,000x maximum payout, Nitropolis 4 combines familiar mechanics with fresh features, making it a worthy sequel that kept fans satisfied.

Veering away from the numbered sequels, the next batch of games saw a change in direction by Elk Studios, as they rolled out a game for each of the criminal animals, the Battle of Nitropolis series. The first spin-off focuses on the fan-favorite Gritty Kitty, offering a dynamic mix of gameplay features that set it apart.

Key highlights include the innovative Feature Reel, which drops modifiers like Nitro Wilds, Nitro Upgrades, and TNT Symbols onto the main reels for explosive action. The game also introduces Assassin Spins, a high-stakes bonus round with persistent coin symbols and a chance to rack up impressive high payouts. Sticky Nitro Reels in the Free Spins round keep the tension high and the wins rolling.

With a max win of 25,000x, up to 262,144 ways to win, and signature Nitropolis chaos, Gritty Kitty delivers both familiar excitement and fresh twists, kicking off this character-driven chapter with style.

Rogue Rats of Nitropolis radically shifts the series with a unique design that is completely different to any of its predecessors. Instead of reels and paylines, it uses an Infinite Game Grid where players guide a rat using different-colored vehicles to collect matching gems. The game features Nitro Multipliers, special symbols, and the chance to upgrade gems or gain instant coin wins.

With high volatility, a max win of 25,000x, and bonus rounds that expand the gameplay, it feels more like an adventure game than a traditional slot. Rogue Rats stands out for its bold mechanics, offering a fresh, engaging experience for those willing to embrace its complexity.

Dirty Dawgs of Nitropolis sees a return to form for the Nitropolis series, returning to the traditional reel and familiar yet exciting mechanics. Set in a lab-like backdrop, this 6-reel slot offers 20 paylines and high-payout symbols, with wins triggered by three to six matching symbols. Although a lot of features will be familiar to fans of the franchise, there are some new additions such as the Nitro Feature Box and Dirty Wilds. These elements add an exciting sense of surprise to the gameplay. The Dirty Wilds, in particular, boost the potential for big wins by filling the reels with expanded Nitro Wild Reels, creating more opportunities for rewarding combinations. 

Rounding off the Battle of Nitropolis series, Pug Thugs of Nitropolis brings fresh mechanics to the series with connecting paylines in all four directions: left, right, top, and bottom. One standout feature is the Nitro Reels, which can stack up to eight symbols and trigger after wins, adding more potential for bigger payouts. The game also introduces Feature Screens in each corner of the grid, each holding modifiers like symbol expansion, coin collection, and Nitro Wild transformations. Additionally, the Nitro Insane feature can randomly place multiple Nitro Reels on the grid, heightening excitement. With two Free Spins rounds, including a Super Bonus with sticky Nitro Reels, Pug Thugs adds a new level of madness and unpredictability to the Nitropolis franchise. 

Going back to the standard sequel variants, Nitropolis 5 builds upon the first four Nitropolis games to create the ultimate showdown. The game boasts 4,096 ways to win, with the ability for each reel to expand up to eight rows. 

The Avalanche feature allows winning combinations to disappear, making room for new symbols to cascade down, increasing the potential for bigger wins. The Nitro Reels are enhanced with Nitro Multipliers, and the NPD Holding Cell feature adds an extra layer of excitement by locking in symbols during respins. The Nitro Booster offers a variety of modifiers, such as Dirty Dawgs and Nitro Wilds, while the thrilling Boss Battle provides a unique bonus round. During this game a 7×8 grid replaces the reels, filled with Coin values or a Max Win symbol. Each Coin hit resets the Shots to three, mimicking popular Hold & Win mechanics with an added twist. The round ends when all Shots are used or the Max Win is hit, and the collected Coin values are paid out, multiplied by your bet.

With a max win of 50,000x, Nitropolis 5 delivers a dynamic and action-packed gaming experience and makes for the perfect place for the game to reach its conclusion.
