Pros & Cons of Gritty Kitty of Nitropolis Slot

This feline spinoff manages to get a lot right, but it does have some issues:

  • Thumbs-Up 25,000x maximum win potential.
  • Thumbs-Up Both respins and free spins bonus modes.
  • Thumbs-Up Several X-iter features.
  • Thumbs-Up Feature reel with loads of reel modifiers.
  • Thumbs-Down A relatively low RTP.
  • Thumbs-Down Repetitive features from earlier games in the series.

Plunge into the depths of Nitropolis once more with ELK Studios’ Gritty Kitty of Nitropolis. This is a spin-off of sorts and the studio plans on releasing quite a few of these in the leadup to Nitropolis 5. Rather than taking all of the city’s shady denizens into consideration, the slot focuses solely on the feline rogues and it manages to tackle this through a breathtakingly gorgeous set of visuals and an immersive soundtrack.

You also get all of the special features that we’re used to seeing in Nitropolis games and I for one, had an excellent time spinning through wilds, avalanche drops, free spins, respins and more.

Gritty Kitty of Nitropolis Slot Game Free Demo

The city can be quite unwelcoming to strangers, so make sure you pop a few rounds on the Gritty Kitty of Nitropolis free demo before playing the game for real money. You can get familiar with all of the special features in play and even decide on an ideal bet level to suit your gambling budget.

Pro Tips:

Anyone who has ever played a Nitropolis game can tell you just how tough these slots can be. It took me quite some time to start triggering special features, so I suggest sticking to a lower bet level to make the most of your gambling budget. Ultimately the best wins come from free spins and respins, so you’ll want to trigger those features as often as possible.

Gritty Kitty of Nitropolis Slot Bonus Features

The mean streets of Nitropolis are teeming with all sorts of rogues and scoundrels and our titular kitty needs to make their way across 6 reels and 4 rows with 4,096 ways to win. Those rows can be doubled in size, which in turn expands the ways to win to up to 262,144.

Fittingly, the lowest-paying symbols in Gritty Kitty of Nitropolis show up as rusty, corroded versions of 10 to A royal cards. Put together six of a kind and you could walk away with wins of up to 0.3x your stake. On the higher end of the pay table, you get more exciting symbols like canned fish, a teapot, a masked Maneki Neko and finally, the Gritty Kitty themselves. They give you a much better payout, with six identical symbols scoring up to 3x your stake.

All pay symbols and wilds in the game can pop up as regular 1×1 symbols, but they can also land in mega versions of 2×2 and 3×3 sizes. These mega symbols can simply crush 1×1 symbols underneath them, or even split into several 1×1 symbols themselves to fit in the available space and fill in any gaps that show up. Mega symbols pay out as several 1×1 symbols.

That’s essentially the gist of it, but it’s just the start. With this being a Nitropolis game there are loads of special features to cover and I’ll walk you through them all below.

Every time you hit a winning combination; the involved symbols are removed from the reels. The only exception here is whenever Nitro Reels are involved. Every reel that has been included in a win is expanded by a row and a new set of symbols tumble down from the top to fill in the new gaps. The first batch of new symbols comes from the Feature Reel and these are followed by fresh symbols off the grid.

This sequence continues to repeat until there are no more wins on the grid. In some instances, the Max Rows feature may randomly activate, and this immediately expands the grid to have a maximum of eight rows active. It also increases your ways to win to the full 262,144.

Nitro Reels

Nitro Reels may land on any given spin, covering two symbol positions. Within these positions, they can have up to 12 1×1 regular pay symbols. You can also get Big Nitro Reels, which take up a larger space of six symbols and can have up to six 2×2 regular pay symbols.

Feature Reel

The feature reel sits atop the main reels and comprises 6 reels and 3 rows. You can get feature symbols, blank spaces or blank cells appearing and the reel is always filled up from the right. Any feature symbols present here will make the transition to the main grid through the avalanche feature, so they purely depend on you scoring a win. They include the following:

  • Nitro Match – Replaces all the pay symbols in Nitro Reels on the same or adjacent reels with a randomly chosen matching pay symbol. This will remain pending if it cannot be immediately implemented and will activate when a Nitro Reel appears or the round ends.
  • Nitro Wild – Replaces all the pay symbols in Nitro Reels on the same or adjacent reels with wilds. It similarly remains pending if there aren’t any Nitro Reels present and activates if these pop up from an avalanche trigger. The Nitro Wild disappears once the round ends.
  • Nitro Upgrade – Upgrade the symbols in Nitro Reels on the same or adjacent reels. Remains pending if there aren’t any Nitro Reels present and activates if they show up from an avalanche. Disappears at the end of a round.
  • TNT Symbol – Explodes all pay symbols from adjacent reels when no more winning combinations exist.
  • Wild Symbol – Steps in for any missing pay symbols. They’re also the highest-paying symbols in the game.
  • Big Coin – Gives an instant payout when it covers the complete feature reel.

Assassin Spins

Assassin symbols covering the entire feature reel will trigger the Assassin Spins. You get three Assassin Spins where coins, Nitro Reels, TNT symbols or block symbols may drop. Any coins that land are locked in place, resetting the spin counter back to three. Nitro Reels will also reset the spin counter. You’ll need to land a Golden Collector symbol to gather the values from all of the coins on the grid.

Scatter Symbol

Scatter symbols are your key to free spins and you’ll need to land three, four, five or six of them to activate 8, 10, 12 or 14 bonus rounds, respectively. Landing more scatter symbols during free spins will similarly add more bonus rounds to your tally.

Free Spins

The free spins bonus has very similar gameplay to the base game. The main difference here is that Nitro Reels are sticky and remain active for the duration of the bonus.


ELK Studios loves popping its X-iter features wherever possible and you get a handful of these here too.

  • Bonus Hunt – Pay 3x your stake and get a single round with more than 3x the chance of triggering free spins.
  • Big Blocks – Pay 10x your stake and get a single round with a guaranteed Mega symbol on both the main grid and Feature Reel.
  • Nitrofest – Pay 25x your stake for a single round with a guaranteed Nitro Reel on both the main grid and Feature Reel.
  • Bonus – Pay 100x your stake for immediate access to the free spins bonus.
  • Super Assassin Spins – Pay 500x your stake for immediate access to Assassin Spins with all eight rows in play.

RTP & Volatility of Gritty Kitty of Nitropolis Slot

Nitropolis games have always been quite challenging and this Gritty Kitty’s adventure is no exception to the rule. Volatility is clocked to a high setting and it’s matched with a rather low RTP of 94%. That figure remains the same even when activating any available X-iter features. It makes for a testy time at the reels, where bonus features and big wins are rather hard to come by.

Both ELK Studios and the Nitropolis slot series are very popular among fans and they have a proven track record for being fair and trustworthy. So, you can play Gritty Kitty of Nitropolis with confidence, knowing that the slot is completely legitimate. For the safest experience possible, I recommend playing it at an equally reputable online casino with strong security features and legit gambling licenses.

Gritty Kitty of Nitropolis Slot on Mobile

The Nitropolean (that’s right!) dystopia knows no bounds and you can jump into the game whenever you like thanks to its brilliant mobile compatibility. The slot runs on both Android and iOS platforms, so you can play on all your favourite smartphones and tablets.

The game’s interface automatically adapts to your screen size and adds in touchscreen controls and this changes accordingly for both landscape and portrait modes. But the graphics, win potential and features remain the same across all platforms.


ELK Studios has a great thing going with the Nitropolis series. It’s a hardcore set of slots with a bold theme, excellent presentation and loads of brilliant features. And Gritty Kitty of Nitropolis is a brilliant addition to the collection.

First of all, the game is visually stunning. The series has always had loads of detail in its graphics and the setting here is just as intricate with excellent designs and animations that bring the murky city world to life. But the best thing about this presentation has got to be the sound design. It’s an incredibly immersive soundscape that places you right there in the middle of it all. The soundtrack speaks volumes of the dystopian, futuristic hellhole that is Nitropolis and it sets the right feel for this incredibly volatile slot.

When it comes to features, Gritty Kitty could potentially divide opinions. I love the Nitropolis formula, so I’m happy to get more of the same in this case. You get both free spins and respins bonus, as well as several reel modifiers that work perfectly well with the avalanche system to create a sense of progression along the way. But if you’re hoping for new and exciting innovations, then you’ll be sorely disappointed.

Win potential is also quite commendable at 25,000x your stake, although this is notably half the amount we got in Nitropolis 3 and 4. RTP is a bit of a sore spot too, with 94% being uncomfortably low for a game like this. It’s not a dealbreaker but it certainly isn’t ideal.

So, ultimately, Gritty Kitty of Nitropolis is a fantastic spin-off, delivering everything you would want from a cyberpunk, post-apocalyptic kitty-filled online video slot.


I’ve inhaled as much toxic waste as I can stomach from the streets of Nitropolis, so it’s high time I bid our Gritty Kitty farewell. But if you have more questions to ask about the slot and its offerings, then write me a message using the contact form below. I’ll get back to you with a direct answer as soon as possible.

Be sure to check out the frequently asked questions below too. They can give you even more details about the Gritty Kitty of Nitropolis and its many features.

Wilds are the highest-paying symbols in Gritty Kitty of Nitropolis. They can award wins of up to six identical symbols.

Wilds drop from the feature reel. To get them, you’ll first have to make a win on the main grid and then have them tumble down to fill in the empty spaces on the reels.

You can buy straight into the free spins bonus using the X-iter feature but this will cost you 100x your stake.

You get two bonus features in Gritty Kitty of Nitropolis. These are the Assassin Spins and Free Spins. Assassin Spins is a respin hold and win bonus, whereas free spins add a couple of modifiers to the main gameplay.

You could win up to 25,000x your stake from Gritty Kitty of Nitropolis.
