Game Overview
I’m sure fans of Elk Studios Nitropolis series will have been massively excited by the recent announcement from the provider that they would be releasing a run of 5 new instalments of the slot over the coming months. Having been exiled by SGt Nitro Wolf from the city of Nitropolis, the four clan members have been training for war and plotting a scheme to return and reclaim the territory. As a result, each of these characters will have a game released which focuses on each of them in turn, prior to the release of Nitropolis 5, which is the culmination of this mini-series and the final battle. Pretty enthralling stuff, right? The first character to appear centre stage is a familiar purple feline friend. She stars in this release titled Gritty Kitty of Nitropolis, a high volatility, six-reel slot with an RTP of 95% and a potential maximum win of 25,000x.
At the beginning of a standard spin, the grid will be set up in a 6-reel, 4-row formation, but each winning drop will grow these rows up to a maximum of 8, resulting in a huge 262,144 payways. Above this main grid is the 6×3 feature reel, which will randomly contain a mixture of blank spaces and game enhancing symbols which will drop into play as symbols involved in winning combinations from the main grid are eliminated and removed. Another staple of the previous games, the Nitro Reel, remains a prominent feature of this version and can contain up to 12 stacked symbols. The free spins bonus found here is also a familiar fixture, with 3, 4, 5, or 6 scatters awarding an increasing number of spins, respectively.
It’s rumoured that the five games in this subset will be dropped a month apart, starting from Feb 24. If you can’t wait that long to test each of them out, we will have the demo version available to play well in advance of each official release date. Check out the first one, Gritty Kitty of Nitropolis, below; it’s free to play!
Gritty Kitty Of Nitropolis Slot Theme, Stakes, Pays & Symbols
The theme of the Nitropolis series centres around a futuristic world of advanced alien animal characters that have evolved to a high level of intelligence and are battling it out for supremacy. If you’d like to catch up on the story so far, why not revisit the last instalment, Nitropolis 4? It’s a high variance slot with a potential maximum win of 50,000x, packed with exciting features and bonus rounds. As for Gritty Kitty of Nitropolis, whilst testing the game, it struck me that elements of its new Super Bonus reminded me of the features on the Money Train games, which also have bonuses centred around landing cash values, multipliers, and collect symbols. The latest in that series is Money Train 4, featuring an enormous maximum win of 150,000x! Can Gritty Kitty of Nitropolis give these recommendations a run for their money? Let’s check out the stats and gameplay to find out, starting with its paytable.
The maximum payout value for each symbol type is achieved by matching six across a payway. The top symbol is, of course, the star of the show, the Gritty Kitty herself, who will return 3x the total stake value per winning combination of six. Next, it’s the Red Dog at 1.5x, the Teapot at 0.75x, and the final premium symbol, the Fish, which pays 0.6x. The non premium symbols are the commonly used A, K, Q, J, and 10, which are all worth 0.3x for a full line of six,
When it comes to the stake options, these range from as low as €0.20 to as high as €100.00, with many well structed options between those extremes, ensuring low, mid and high rollers can all find a bet size comparable to the bankroll.
Gritty Kitty Of Nitropolis Slot Base Game
Gritty Kitty of Nitropolis typically operates on a six-reel, four-row grid, but the row positions will expand with each winning cascade, growing to as high as 8, creating a potential maximum high of 262,144 payways. Wins are achieved by matching a minimum of 3 corresponding symbols from left to right, commencing on the leftmost reel. The cascading reels system is also utilised, with any symbols involved in a win being removed from the grid which creates additional space for drop downs from the 6×3 Feature Reel above, that contains special symbols.
Feature Reel & Avalanche
The feature reel is located above the main reel set and comprises 6 reels and 3 rows. During each spin, it will be randomly filled with empty positions and feature symbols. If winning combinations are on the main grid, the symbols involved will be removed from the grid, and feature symbols may cascade down into play from the feature reel. As feature symbols tumble down, more empty spaces or feature symbols will fall into the spaces left in the feature reel.
Feature Symbols
The symbols that can be found in the feature reel are as follows:
- Nitro Reels: Standard nitro reels contain up to 12 1×1 paytable symbols. Big nitro reels contain up to 6 2×2 paytable symbols.
- Big Symbols: Paytable symbols that appear in sizes 1×1, 2×2, and 3×3.
- Max Rows: Expands main reels up to the maximum of 8 row positions tall.
- Nitro Match: Transforms all symbols within nearby Nitro Reels to a random matching paytable symbol.
- Nitro Wild: Transforms all symbols in nearby Nitro Reels to wild symbols.
- Nitro upgrade: upgrades the number of symbols in nearby Nitro Reels.
- TNT Symbol: Removes all paytable symbols from the grid. It only activates once there are no further winning combinations.
- Wild Symbol: Appears in various sizes up to 3×3, substitutes for all other paytable symbols.
- Big Coin: Awards an instant multiplier payout of the equivalent stake value if it covers the whole feature reel.
Gritty Kitty Of Nitropolis Slot Bonus Features
Landing 3, 4, 5, or 6 scatter symbols during any single spin will award 8, 10, 12, or 14 free spins, respectively.
Free Spins
During this feature, any Nitro Reels that land and any reel expansions that occur will be persistent for the duration of the bonus. The bonus game can be retriggered by landing a minimum of three more scatters during any one spin.
Assassins Spins
If the assassin symbols covers the complete size of the feature reel, then the Assassin Spins feature will be awarded. All standard paytable symbols are removed during this feature, and only coin symbols, nitro reels, TNT symbols, collectors, and blockers are present.
The game starts with 3 lives, which are reset each time a coin symbol or nitro reel lands. Coin values that land on the grid are held in place, as are nitro reels, which will be filled with coin symbols. TNT symbols will clear blockers from the main reels, allowing space for nitro reels to drop down from the feature reel above.
The golden collect symbol will collect all current coin values displayed on the grid. The feature ends once there are 3 spins in a row where no further symbols land. The final payout value will be determined by the value of the coins collected multiplied by the current stake value.
X-iter
Players have the option to purchase various enhanced game modes via the X-Iter button. The options are as follows:
- Bonus Hunt: More than triple the chance of triggering the bonus game. Cost – 3x
- Big Blocks: Guaranteed big symbols on the main grid and feature reel. Cost – 10x
- Nitrofest: Guaranteed nitro reels and enhancers on the main grid and feature reel. Cost – 25x
- Bonus Buy: Randomly awards a 3, 4, 5, or 6 scatter free spins bonus. Cost – 100x
- Super Bonus Buy: Activates the Assassins Spins bonus. Cost – 500x
Pros
- Extremely engaging gameplay and storyline.
- The new version of Super Bonus is a welcome change and has good potential.
- Bold, colourful artwork
Cons
- The maximum win is half that of the previous Nitropolis game.
- Low RTP of 94%
Gritty Kitty Of Nitropolis Slot Review Final Thoughts
The Nitropolis series has been one of the provider's most successful creations, and that is built upon here in this most recent version. As ever, the standard gameplay is enthralling; there’s always something to look out for, and it feels like a big hit is always around the corner. That doesn’t often materialise, but in fairness, this game did seem to be fairly generous with sizeable wins during testing. The re-vamped super bonus is also a good addition and seems to pack plenty of potential that seems more achievable than in the past. I did see a 5,000x coin scroll past a few times! The RTP level is slightly low, and the maximum win halved compared to Nitropolis 4, but overall, it is a brilliant game, and I look forward to seeing what the other upcoming games in this series will have to offer. To conclude, the idea of producing a mini-series of games culminating in a big release at the end is excellent, and Elk should be commended for this innovative idea.
