Rogue Rats of Nitropolis Slot RTP, Details & Wager Limits

Reels/Paylines: 5×5 grid + cluster pays

Stakes Range: 20p to £100 per spin

Max Win: 25,000 x stake per spin

RTP: 94%

The Rogue Rats of Nitropolis slot is played on an initial 5×5 grid and uses the cluster pays mechanic. However, the grid is actually infinite, it just starts 5×5 in size. Wins are formed by the rat moving around the desert on an infinite game grid collecting vertically or horizontally adjacent payout symbol clusters and activating feature symbols.

The rat will move around in different coloured vehicles and will only collect paying symbols that are the same colour as the vehicle. But with every ‘spin’, the rat will change vehicles as the gas runs out on the previous one. Even though you’ll see a larger grid, the rat can only initially see a 5×5 grid.

Each move will consume fuel in the vehicle the rat is in. Picking up symbols and shooting or collecting feature symbols will award extra fuel, thus keeping the game round going. If you manage to max out the fuel gauge. you’ll get a small boost where the fuel is limitless until you collect another coin. This is known as the Nitro Fuel Boost. The game round or spin will end when no more collections are made.

Stakes range from just 20p up to £100 per spin. Like all ELK slots, hit the coins icon beside the reels to adjust your total bet. You will have 12 predefined bet values to pick from. Autospins are also possible but only if you’re a non-UK player.

The Rogue Rats of Nitropolis RTP is 94%, which is very typical of many slots nowadays from this provider. In terms of volatility, it’s in the high range and rated 8 out of 10 by ELK Studios. It also comes with a hit rate of 33%, which means that a third of all spins on average will result in a winner.

The maximum win is 25,000 x bet. This matches the figure from the last release – Gritty Kitty of Nitropolis.

Compatibility: Mobile, Tablet, Desktop


The reels are set in the desert, but it’s more of a racing around the desert type game than a typical slot. It adds a unique dimension to the gameplay which is fantastic. The animations are brilliant and I love the rat camera above the reels alongside the multiplier info and the fuel gauge. The visuals are superb overall.

In terms of the soundtrack, it’s rather dramatic as you’re driving around the infinite grid on your bike. Land the Bonus Game and the audio switches to a more face-paced heavy metal-like sound, which adds to the overall intensity. The added sounds when shooting and racing around are great too.

On the reels, the symbols are all made up of different coloured gemstones. They all start from level 1 and can reach level 6. The red gemstone pays the most, awarding 0.2 x bet for level 1 collections up to 2 x bet for level 6 collections. Remember that you can only collect symbols matching the colour of your vehicle at the time.

As ELK Studios is a mobile-first provider, all of its games are produced using the latest HTML5 technology. This means the Rogue Rats of Nitropolis mobile slot can be enjoyed on iOS and Android devices. It’s also available on tablets, laptops, and PCs.Although a smaller screen will suffice, I do think you get a much better experience of the best grid slots on a bigger screen.

Rogue Rats of Nitropolis Bonus Features

There are 9 bonus features to enjoy in the Rogue Rats of Nitropolis slot game. From free spins and symbols upgrades to progressive multipliers and instant coin wins, there’s a lot going on. Read on as we explain everything so that you can fully understand all of the bonus features.

Nitro Multiplier

An active Nitro Multiplier is applied to coins and payout symbols matching the colour of the rat’s vehicle. When a Nitro Multiplier is activated by shooting the NPD Radar symbol during a game round, a new higher multiplier value is prepared but locked.

Feature Symbols

There are plenty more feature symbols you’ll come across in the game. These include:

  • Nitro Blob – Shooting one of these will upgrade visible payout symbols to a higher payout level.
  • Coins – Destroying NPD Cruisers and Helicopters will see you collect coins. You’ve even got a chance here to find a Police HQ or collect a max win coin!
  • New Vehicle – Find a new vehicle to change the symbol colour to collect.
  • Nitro Fuel – Each positional movement consumes fuel. You can gain extra fuel by picking up payout symbols or shooting at feature symbols.
  • Missile Silo – Shooting at these will launch a missile that increases the rat’s visible area.
  • Turret – Reach features further away by driving into one of these.

Bonus Game


Collect 2 Bonus symbols to trigger the bonus feature. You will be awarded 3 free spins. If one of the 2 Bonus symbols is a Super Bonus symbol, you will trigger the Super Bonus Game instead of the normal one. In the Super Bonus Game, each spin will start with a Nitro Fuel Boost.

The payout level of the coloured payout symbols and the current active Nitro Multiplier are carried over to the bonus round. Simply spin away (or drive around) until the free spins run out.

Retriggers are possible.

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 4 times likely to trigger the Bonus Games and 1 Bonus symbol is already collected.
Big Blocks 10 x bet 1 spin with extended visibility and double the amount of starting fuel.
Nitrofest 25 x bet 1 spin with double the amount of starting fuel. Pay symbols are removed and coins are more frequent.
Bonus 100 x bet Buy the regular Free spins feature
Super Bonus 500 x bet Buy the Super Bonus Game.

Rogue Rats of Nitropolis Verdict: unexpected and superb

Based on our expert’s review. Reviewed by
Rogue Rats of Nitropolis Slot

ELK Studios has brought non-standard gameplay to the desert. It won’t suit everyone, but the innovation is brilliant as you go in search of Nitro whilst weakening the Nitropolis Police Department along the way.

  • 25,000 x bet max wins
  • Superb graphics/soundtrack
  • Unique gameplay
  • 94% RTP rate
  • Not easy to land free spins

When I first loaded the Rogue Rats of Nitropolis slot, I certainly didn’t expect to see a rat riding around in the desert as part of the main action. But I must admit that it is a brilliant idea. Gone are the standard symbols and reel setup you usually associate with slots. Hats off to the developers here. I was expecting to see a similar setup to previous titles in this series but no – the innovation is fantastic and it works really well.

The only thing I would say to begin with is to be patient. It’s not easy to understand at first and you’ll be driving around in your vehicle wondering why you’re not collecting everything that appears on the screen. Once you realise you can only collect the same colour symbols that match your vehicle, the picture becomes a whole lot clearer. Everything starts to make sense after a while and I’m impressed with how everything has been put together.

While this type of gameplay won’t suit everyone, it’s a refreshing change to the norm. It still packs a punch with 25,000 x bet max wins and the bonus features are great. Landing some free spins may take a bit of time, though, as I found out while testing. Still not sure? Don’t hesitate to try our free demo first and test the game out fully before using any of your own funds.

Looking for more action away from the normal slot setup? Check out the likes of Mad Cars from Push Gaming or ELK’s Pirots 2 slot. The gameplay is fantastic and they’ve both scored highly in our reviews in terms of overall rating.
