How to Play

The reels sit among vats of glowing green liquid and flickering neon. Symbols include high-card emblems, a fish dish, a teapot, and two battle-ready felines. 

On PCs, iOS, Android, or Windows devices, tap the coin stack to choose a stake from 0.20–100.00 per spin. 

The X-iter button (where permitted) offers feature buys; UK players won’t see X-iter, Autoplay, or Turbo due to local regulations. Use the three-line menu to open the paytable and feature guide.

Betting Options

• Layout: 6 reels, 4 rows, 4,096 ways (ways expand with rows)
• Stakes: 0.20–100.00 per spin (12 preset options)
• Feature Buys (X-iter): Available outside the UK
• Devices: Desktop, iOS, Android, Windows

Symbols & Payouts

Neon card ranks cover low pays, with thematic icons (fish, teapot) and cat characters as premiums. 

A wild substitutes for regular symbols to complete wins. Oversized Big Symbols (2x2 or 3x3) can land, counting as multiple positions; if they can’t drop cleanly, they crush or split to fit.

Features & Bonuses

Avalanche Wins & Expanding Rows

Every win triggers an Avalanche: winning symbols explode and new symbols drop in. Each Avalanche in the same sequence adds +1 row on the affected reels, up to 8 rows max—boosting ways and the chance of chaining further wins.

Feature Reel Modifiers

A 6x3 Feature Reel slides above the grid and can drop modifiers onto the main reels after wins:

• Nitro Reels: Stack up to 12 of the same symbol in a column for extra ways.
• Nitro Match: Turns all Nitro Reels into the same paying symbol.
• Nitro Wild: Drops wilds onto all Nitro Reels.
• Nitro Upgrade: Increases symbols per Nitro Reel stack.
• TNT: Blows up paid symbols on connected reels to trigger another Avalanche.
• Wild Symbol: Adds wilds to help complete combos.
• Big Coin: If it covers the entire Feature Reel, awards an instant coin prize.
• Big Symbols: 2x2/3x3 symbols that crush or split if needed.
• Max Rows: Instantly pushes reels up to 8 rows for maximum ways.

Free Spins

• Trigger: Land 3/4/5/6 Bonus symbols for 8/10/12/14 free spins.
• Sticky Nitro: Any Nitro Reels stay active for the remainder of the feature.
• Persistent Expansion: Once a reel expands in free spins, it doesn’t shrink until the round ends.
• Retriggers: Additional Bonus symbols can award extra spins.

Assassin Spins

When the Assassin covers the Feature Reel, you enter a hold-&-win style round with 3 spins. Only coin symbols (which lock) or blanks appear; landing any coin resets the counter to 3. 

The Golden Collector cat scoops all visible coin values. The feature ends after three consecutive blanks or when the grid is filled.

RTP, Volatility & Max Win

• RTP: 94.00%
• Volatility: High
• Maximum Win: 25,000x stake (up to 2,500,000.00 at max bet)

Expect streaky sessions with the potential for explosive runs when Avalanches, Nitro enhancements, and bonus rounds align.

Verdict

The Gritty Kitty of Nitropolis slot machine is a feature-dense, high-variance brawler. Avalanches that grow the grid, a modifier-packed Feature Reel, sticky Nitro in free spins, and the coin-collecting Assassin Spins keep momentum high. 

The RTP is on the low side, but the 25,000x ceiling and relentless synergy of mechanics make this a compelling pick if you enjoy volatile, combo-driven gameplay.
