Feature Reel

A special Feature Reel sits directly above the main reel set, comprised of 3 rows, 6 reels, and a mix of Feature symbols and empty positions. With each new spin, symbols in this reel slide into view from the right. Feature Reel symbols only become active when they drop onto the main reel set.

  • Nitro Upgrade – Upgrades the number of symbols in Nitro Reels on the same reel or adjacent ones.  If there are no Nitro Reels, the feature will remain pending until a Nitro Reel appears.
  • Nitro Match – Replaces all symbols within the Nitro Reels with a matching paying symbol chosen at random, affecting Nitro Reels on the same or adjacent reels. This feature will remain pending until a Nitro Reel appears.
  • Nitro Wild – Replaces all symbols within Nitro Reels with Wild symbols, affecting Nitro Reels on the same or adjacent reels. This feature will hold until a Nitro Reel appears.
  • TNT Symbol – Removes all paying symbols on the same or adjacent reels. TNT symbols activate when there are no more wins in view.
  • Wild Symbol – Acts as a regular Wild, substituting for all High and Low-paying symbols.
  • Big Coin – Awards an Instant Prize payout when it covers the entire Feature Reel.

Each time a win forms, all winning symbols except Nitro Reels are removed from play, making room for new symbols to drop in via an Avalanche Feature. Each reel that included a win will expand by +1 row, up to a max of 8 rows high.  Symbols in the Feature Reel above empty positions will drop down into the main reel set.

Nitro Reels

When in view, Nitro Reels will cover two symbol positions, containing 4, 6, 8, 10, or 12 identical 1×1 paying symbols. A big Nitro Reel will always cover 6 symbol positions, containing 2, 3, 4, 5, or 6 identical 2×2 paying symbols.

Assassin Spins

Assassin Spins trigger when an Assassin symbol covers the entire Feature Reel. Once active, only Coin symbols, Nitro Reels, TNT symbols, and Blockers are in play.

During Assassin Spins, 3 Refilling Spins are awarded. Each time a new symbol lands in view, it will reset the remaining spins back to 3. All Coin symbols are persistent during this time, and their values are collected at the end of the Assassins Spins round. Landing a special Golden Collector symbol during this round will collect the values of all Coin symbols currently in view.

Gritty Kitty of Nitropolis: Our Verdict

Gritty Kitty of Nitropolis, the first in ELK Studios of Nitropolis series takes players on a captivating adventure through Nitropolis. Set in the dystopian suburb of Tokyotown, the game’s aesthetics and storyline are both imaginative and engaging.

To receive an individual game for each character was quite a surprise, and we think Gritty Kitty of Nitropolis starts the series right with dynamite mechanics, great potential and that unmistakable Nitropolis feeling that things could kick off at any given moment. So many different cogs work in unison to deliver a varied and interesting game, and though Gritty Kitty of Nitropolis is not the first in the whole series, it feels fresh, new and exciting.

A standout aspect of this game is the Feature Reel, which introduces additional elements like Nitro Upgrades, the beloved Nitro Wilds, and the thrilling TNT Symbol, all contributing to dynamic gameplay and potentially big wins. The Assassin Spins and Free Spins rounds are the game’s crown jewels, offering players high-intensity action with the potential for significant payouts, especially with the sticky Nitro Reels during Free Spins. The X-iter options are a commendable addition, giving players the flexibility to tailor their gaming experience, albeit at a higher cost. This of course, is locked for UK players, but even without bonus buys we feel like Gritty Kitty is a very playable game with a great base game.

Overall, Gritty Kitty of Nitropolis is a proud addition to the series with more of the same thrilling features that we’ve enjoyed previously, plus some new ones.

ELK Studios has since released the latest in the Nitropolis series, Rogue Rats of Nitropolis Slot. Check out our review!
