Nitropolis 5, released in July 2024, is a dynamic new addition to Elk Studios’ popular Nitropolis series. Like previous instalments, we join gangs of animals in a post-apocalyptic world competing for control of the city. The slot is highly volatile with a rich narrative that builds on the adventures of the Gritty Kitty, Rogue Rats, Dirty Dawgs, and Pug Thugs gangs.

About Nitropolis 5

Nitropolis 5 is highly detailed and immersive, capturing the chaotic essence of a dystopian city. The reels are set against a devastated urban landscape, with high-tech, neon-lit buildings and mechanical elements. Symbols on the reels include low-paying card suits and medium-paying emblems of the four gangs. High-paying symbols are the four gang leaders. Special symbols include the Nitro symbol, which is the wild, and the scatter, which is a truck.

Nitropolis 5 is played on 6 reels with 4 to 8 rows from 20p up to £50 per spin. The RTP is below the industry average of 94%, typical in Elk slots. The slot is classified as highly volatile, so expect substantial wins but less frequently, and the maximum win can reach as high as 50,000 the bet.

Gameplay

Features in Nitropolis 5 include the Avalanche mechanic, Wild Symbols, Big Symbols, Nitro Reels, Nitro Multipliers, Nitro Booster, NPD Holding Cell, and various bonus games.

Avalanche Mechanic

After landing a winning combination, the Avalanche feature triggers. Winning symbols are removed from the reels, and new symbols cascade down to fill the empty spaces. An additional row is added each time, expanding the grid up to a maximum of 8 rows. The avalanche feature continues until no new wins are created.

Wild Symbols

The Wild symbols substitute for all symbols, barring the scatter and special feature symbols, and help create winning combinations.

Big Symbols

Big Symbols land randomly in sizes of 2×2 or 3×3. These symbols cover multiple positions and increase your chances of landing a winning combination.

Nitro Reels

Nitro Reels come in two sizes: regular Nitro Reels covering two positions and Big Nitro Reels covering six positions. Nitro Reels contain 1×1 and 2×2 multiplier symbols and can include scatter symbols. Nitro Reels remain on the reels for subsequent spins and can result in multiple winning combinations.

Nitro Multipliers

Nitro Multipliers land with values worth 4x, 6x, 8x, 10x, or 12x. The multiplier is applied to all wins in view, and they multiply if more than one is present on the reels, leading to lucrative payouts.

Nitro Booster

Above the reels is the Nitro Booster, which displays up to 11 different features that affect the main or Nitro Reels. These features include expanding the reels to 8 rows, activating the “Both Ways” feature for wins from both left and right, and adding more wilds or multipliers to the Nitro Reels.

NPD Holding Cell

Triggered randomly during the spins, a random symbol is selected. If the chosen symbol is part of a winning combination, it locks on the reels for a respin. The feature continues if more of the selected symbol’s land or another NPD Holding Cell feature is active. The locked symbols are paid out when the feature ends.

Bonus Games

3 or more scatters on a spin trigger the bonus game, awarding 8 to 20 free spins depending on the number of triggering scatters. During the free spins, Nitro Reels remain sticky, and additional rows are added after each winning spin, increasing the winning potential.

If one or more of the triggering scatters are Super scatters the Super Bonus Game triggers. The Super Scatter only appears in the Nitro Reels. You start with the maximum rows and Both Ways active, and the NPD Holding Cell feature triggers on every free spin.

Conclusion

Elk Studios’ Nitropolis series has proved highly successful, and the fifth instalment is no exception. Each new addition comes with improved and refined features. The fifth comes with the Nitro Boost and the NPD Holding Cell, each providing more thrilling gameplay with the potential for substantial prizes. Whether you’re a fan of the Nitropolis series or new to the saga, Nitropolis 5 is a slot that promises you a thrilling adventure.
