gritty-kitty-of-nitropolis-slot-base-game

With a dystopian/Japanese theme, the Gritty Kitty of Nitropolis slot is the first game from the Battle of Nitropolis series. Sergeant Nitro Wolf from the Nitropolis slots series forced the 4 clans out of Nitropolis. After years in exile, the 4 clans are ready to go back and reclaim Nitropolis. There will be a slot game based on each of the clans with Nitropolis 5 coming at the end.

In this game, Gritty Kitty went back to suburb Tokyotown in search of the Golden Shuriken. It’s a weapon that can help defeat Sergeant Nitro Wolf. The setting is a Japanese street which has a futuristic yet rundown feel. You’ll notice the hip-hop/EDM style soundtrack which is superb.

On the reels, there are low-value A, K, Q, J and 10 royals. The higher-value symbols include canned fish, teapots, a metallic Maneki-Neko and Gritty Kitty himself. Gritty Kitty is the best-paying symbol awarding 1, 1.25, 1.5 or 3 x your total bet for 3, 4, 5 or 6 in combination. Symbols can appear in 1×1, 2×2 and 3×3 size.

Gritty Kitty of Nitropolis comes with a Wild symbol that substitutes for all paying symbols above. You’ll also come across plenty of other symbols including TNT, Big Coin, Assassin, Satellite Bonus and various feature symbols. More details on how they influence the gameplay can be found below in the Bonus Features section.

Gritty Kitty of Nitropolis Mobile

gritty-kitty-of-nitropolis-mobile-slot

Released on the 6th of February 2024, Gritty Kitty of Nitropolis is compatible with all devices. Produced using HTML5 technology, you can play on mobile, tablet and desktop devices. This includes one powered by Windows, iOS and Android operating systems.

Gritty Kitty of Nitropolis Bonus Features

The Gritty Kitty of Nitropolis slot has 10 bonus features. There are Avalanches for continuous spins and more ways to win as well as Big symbols and Nitro Reels. With a Feature Reel that brings various features and special symbols in play, there are free spins with persistent Nitro Reels and rows. Collect coins with the help of various symbols in the Assassin Spins feature. It’s all action.

Avalanche feature

The Avalanche feature is triggered when any winning combination is formed. Winning symbols are removed from the reels and the remaining symbols drop down to fill the empty spaces. New symbols then drop in which gives you the chance to win again. More importantly, each win sees 1 more row added on each reel you win on.

This will lead to more ways to win and a higher chance of forming winning combinations. Avalanches continue as long as you keep winning and there are up to 8 rows on each reel which will lead to 262,144 ways to win:

Nitro Reels feature

Like in previous Nitropolis slots, Nitro Reels will cover 2 symbol positions and contain up to 12 1×1 payout symbols. The large Nitro Reels cover 6 symbol positions and contain up to 6 2×2 payout symbols.

Feature Reel

Above the main grid, there is a Feature Reel which spans 6 reels and 3 rows. It contains feature symbols, empty symbols and empty cells. Feature symbols become active when they drop onto the main grid, via the Avalanche feature. Here’s what you can benefit from:

  • Nitro Upgrade feature: upgrades Nitro Reels symbols and adjacent reels. It remains pending until a Nitro Reel appears or the spin ends.
  • Nitro Match feature: replaces Nitro Reels symbols to a random paying symbol as well as on adjacent reels. It will remain pending until a Nitro Reel appears or the spin ends.
  • Nitro Wild feature: replaces all Nitro Reels symbols with wilds and affects adjacent reels. As with above, the feature is pending until a Nitro Reel appears of the current spin finishes.
  • TNT Symbol feature: removes all paying symbols on the same and adjacent reels when no more wins appear.
  • Max Rows feature: this expands the grid size up to the maximum 8 rows for 262,144 ways to win.
  • Wild: standard wilds, which substitute for paying symbols can appear.
  • Big Coin: this awards an instant payout when covered the complete Feature Reel.

Assassin Spins feature

gritty-kitty-of-nitropolis-slot-assassin-spins-feature

The Assassin Spins feature is triggered when the Assassin symbol covers the whole Feature Reel. With 3 spins awarded, coin symbols, Nitro Reels, TNT symbols or blockers can land.

When a coin symbol lands, it locks in position and the spins tally resets to 3. Nitro Reels also reset the spins tally. If a Golden Collector symbol, the Golden Shuriken, lands, it collects all values from coins on the grid. The feature ends when you run out of Assassin spins.

Free Drops feature

gritty-kitty-of-nitropolis-slot-free-drops-feature

Landing 3 or more Satellite Bonus symbols will trigger the Free Drops feature. 3, 4, 5 or 6 Satellite Bonus symbols will award 8, 10, 12 or 14 free spins respectively.

3 or more landing during the feature will result in additional free spins being won (determined in the same way as when you triggered the feature). Importantly, all Nitro Reels are row expansions are persistent/sticky.

X-iter feature

For non-UK players, there is an optional X-iter feature. This allows you to buy your way into different game modes. The 5 options range from 3 x bet per spin up to 500 x your total bet:

Mode Cost Description
Bonus Hunt 3 x bet More than triple the chance of triggering the Free Drops feature
Big Blocks 10 x bet 1 spin with a guaranteed Big Symbol in the main grid and Feature Reel
Nitrofest 25 x bet 1 spin with a guaranteed Nitro Reel in the main grid and Feature Reel
Bonus 100 x bet Entry to Free Drops feature
Super Assassin Spins 500 x bet Entry to Assassin Spins feature with max rows

Gritty Kitty of Nitropolis Verdict: high-energy, thrilling + chaotic

Gritty Kitty of Nitropolis Slot

Gritty Kitty of Nitropolis sees you go in search of the Golden Shuriken to defeat Sergeant Nitro Wolf in a dystopian Tokyotown for wins of up to 25,000 x bet.

Pros
  • 25,000 x bet max wins
  • Excellent graphics/soundtrack
  • Chaotic/high-adrenaline bonus features
Cons
  • 94% RTP rate
  • Gameplay can appear confusing

The Gritty Kitty of Nitropolis slot game is the first from the Battle of Nitropolis series. ELK Studios has made quite the impression as the graphics and visuals are excellent. The soundtrack is a fusion of various styles with the heavy metal soundtrack in the Assassin Spins a real treat.

Dystopian, futuristic, chaotic and high-adrenaline are a few words that come to mind when describing this onslaught. Wins lead to avalanches which brings more rows and ways to win into play. Big symbols from the ‘Gold’ series feature as well as Nitro Reels found in previous Nitropolis slots. The Feature Reel is similar to the Triple Cool Reel in Tropicool 2.

The Assassin Spins feature is a respins/hold ‘n’ win style game. Nitro Reels can see more coins appear and TNT symbols bring more coins into play. The Golden Collector symbol is like the Collector symbol in Relax Gaming’s Money Train 4. Free spins are pretty standard with Nitro Reels and rows being persistent.

With 25,000 x bet max wins, Gritty Kitty of Nitropolis offers plenty of action which can explode into life with the various Feature Reel symbols. I particularly like the Nitro Wild feature where Nitro Reels and adjacent symbols are replaced with wilds.

In summary, the Gritty Kitty of Nitropolis slot is a well-designed game that kicks off the Battle of Nitropolis series in style. If you’re a fan of Nitropolis games, you’ll love this instalment. It does offer half the win potential of Nitropolis 4 but with the same 94% RTP rate though.
