Nitropolis 2 Slot RTP, Details & Wager Limits

Reels/Paylines: 6 reels + up to 191,102,976 ways to win

Stakes Range: 20p to £100 per spin

Max Win: 10,000 x stake per spin

RTP: 95%

The Nitropolis 2 slot starts off with 6 reels, 4 rows and 4,096 ways to win. Winning combinations are formed by landing 3 or more matching symbols from left to right on adjacent reels and beginning from reel 1.

The stakes are standard for an ELK Studios slot game as you can spin away from 20p to £100 per spin. There’s an Auto Spin function where 10, 25, 50 or 100 auto spins can be selected. There’s also a Quick Play mode which allows for faster spins. Both these extras won’t be available in the UK from the end of October 2021.

The Nitropolis 2 RTP is 95% which is below the 96% average (the original Nitropolis slot has a 96% RTP rate). Expect a win every 5 spins on average as the hit frequency rate is 20%.

Highly volatile, it’s classed by developer ELK Studios as 8/10. You can win up to 10,000 x your total stake per spin. The key to this is by increasing the number of ways to win to over 191 million (more details below).

The Nitropolis 2 slot is the sequel to Nitropolis which was released by ELK Studios in November 2020. Set in a post-apocalyptic world, it feels like the 1982 Blade Runner film which is set in a dystopian future. It has a comic book feel to it.

With similar visuals to the original game, you’ll see futuristic high-rise buildings in the backdrop. You will notice the unique and rather hypnotising soundtrack which add to the chaos it can cause. There are 3 animal clans in the sequel as opposed to 3 in the original version: the Dirty Dawgs, the Gritty Kitties and Pug Thugs.

Symbols on the reels include A, K, Q and J royals. Then you have Pug Thugs, Gritty Kitty and Dirty Dawgs Wanted posters. There’s also a Pest Control symbol. The higher value symbols include the Pug, Kitty and Dawg boss. The top paying symbol is the Pest Sergeant that pays 0.7, 0.8, 0.9 or 1 x stake for 3, 4, 5 or 6 in combination.

The no dog fouling sign is the wild symbol. This substitutes for any symbol except the bonus symbol. The wild pays like the Pest Sergeant (up to 1 x stake for 6 in combination). Here’s what each of the symbols pay:

Symbol Payout
J 3, 4, 5 or 6 = 0.1, 0.2, 0.3 or 0.4 x stake

Nitropolis 2 Bonus Features

Nitropolis 2 comes with a total of 12 bonus features. With Nitro Reels which increase the number of ways to win as respins, there are 8 Nitro Booster features which give you various extras including win both ways payouts. These all apply in the free spins.

Nitro Reels feature

nitropolis-2-slot-nitro-reels-feature

Like in the original game, the Nitro Reels feature is key to big wins. Randomly on any spin, the Nitro Reels can come into play. Nitro Reels cover 2 symbol places and contain 4, 6, 8, 10 or 12 payout symbols. If you have 12 symbols for example, you will see 12 1×1 symbols appearing across 2 symbol places.

This can lead to a lot more symbols appearing on each reel. There’s a box above the reels which highlights how many ways to win you are playing with. Each reel can contain 24 symbols each meaning there’s 191,102,976 ways to win. You read that right, that’s over 191 million ways to win.

Winning Respin feature

When you land a winning combination, all symbols and Nitro Reels that are part of a win will trigger the Winning Respin feature. All symbols and Nitro Reels then respin individually with the non-winning symbols remaining in place. This gives you the chance to win again and again. Winning respins continue as long as new wins are formed.

Nitro Booster features

nitropolis-2-slot-nitro-upgrade-feature

Unlike the original game, Nitropolis 2 comes with 8 Nitro Booster features. You will notice a feature reel above the reels. 8 different feature symbols can land and impact the reels below them. Here’s what to expect:

  • Respin feature: all Nitro Reels and bonus symbols lock in position and the Nitro Booster and all reels respin
  • Both Ways feature: all wins are paid from left to right and right to left
  • All Wild feature: all sticky and landing Nitro Reels only contain wild symbols
  • Nitro Wild feature: Nitro Reels landing in the same column only contain wilds
  • All Premium feature: all Nitro Reels landing will contain only high value symbols
  • All Match feature: all Nitro Reels landing match up with a symbol on the reel to the left
  • Nitro Match feature: Nitro Reels landing match up with a symbol on the reel to the left
  • Nitro Upgrade feature: same column Nitro Reels upgrade and add extra symbols to the Nitro Reels

Bonus Game feature

nitropolis-2-slot-bonus-game-feature

The Salty Dog car is the bonus symbol. Landing 3 or more bonus symbols will trigger the Bonus Game feature. The more bonus symbols, the higher the number of free spins:

3 bonus symbols 10 free spins
4 bonus symbols 15 free spins
5 bonus symbols 20 free spins
6 bonus symbols 25 free spins

Once in, all Nitro Reels lock in position for the duration of the feature. This means you could play every free spin with over 13 million ways to win. The Nitro Upgrade extra can land in the Nitro Booster to increase the number of symbols on the Nitro Reels for more ways to win.

All Nitro Booster features can land in the free spins to give you Both Ways wins, wilds and only high value symbols. Lastly, you can land bonus symbols in the Nitro Booster and the main reels meaning you can win additional free spins.

In some countries, there’s an X-iter feature. You can choose from 5 different game modes. Here’s what they offer:

X-iter 1 5 x stake Guarantees a winning spin
X-iter 2 25 x stake 3 spins with a feature/bonus symbol on every Nitro Booster position

Originality








The Nitropolis 2 slot is very similar to the original game in terms of looks and bonus features. The addition of the Nitro Booster features is a welcome one and can add plenty of variety to your experience. The San Quentin slot by Nolimit City also have a top row displaying symbols for added extras.

In my opinion, the soundtrack has been improved but could see players reaching for the mute button. With so many moving parts and the Nitro Reels, the excitement can be high due to the potential number of ways to win. Saying that, the max win of 10,000 x stake is exactly like the original which I thought ELK Studios would have increased. This is the only downfall considering there’s over 191 million ways to win as opposed to over 85 million in the original.

If you want a similar chaotic yet exciting experience, the Punk Rocker slot (from Nolimit City) delivers this as well as potential payouts of 15,072 x stake per spin.

Pros
  • Superb graphics + soundtrack
  • Over 191 million ways to win
  • Big win potential
Cons
  • Can feel a little complicated
