Nitropolis 2: Stakes & Slot RTP
Nitropolis 2 starts out as a pretty much traditional video slot with 6 reels, 4 rows and 4,096 ways to win. All winning combinations start from left to right with at least 3 matching symbols landing on adjacent reels.
The stakes are pretty standard too. You can start spinning for as little as 20p per spin. Max bet is £100 per spin. Auto Mode and Quick Play Mode are also available. You can make the machine play for you by adjusting the auto spin selector to 10, 25, 50 or 100 auto spins.
The RTP level in Nitropolis 2 comes in at slightly below average. With a 95% rate it’s actually below the original Nitropolis slot which has an RTP of 96%. That said, this is a high-volatility game with a 20% hit frequency and wins that can land at 10,000x your stake per spin.
Nitropolis 2: Audio & Design
Call it post-apocalyptic or futuristic or even dystopian. This is a slot that presents players with a world of grime, steel and chemicals in which canine clans fight for power. The design has clearly been inspired by the world of comics, preserving the visuals of the original game. A cool punk-rock soundtrack plays in the background, occasionally punctured by sound effects highlighting whatever is happening on the grid.
The grid itself is mainstream with symbols including A, K, Q and J royals, Wanted posters, a Pest Control poster and posters of the main characters. The highest value symbol is the Pest Sergeant who rewards players with 0.7, 0.8, 0.9 or 1x total stake for 3, 4, 5 or 6 symbols in a winning combination. The wild symbol is basically a no dog poop sign. It substitutes all symbols except for the Nitro Wolf bonus symbol.
Nitropolis 2: Bonus Features
There’s a whopping 12 bonus features in Nitropolis 2 that can be grouped into two chief features: Nitro Reels and Nitro Boosters. The Nitro Reels increase the number of ways to win with up to 12 payout symbols. The Nitro Boosters give you respins and win-both-ways payouts. Let’s take a closer look.
The Nitro Reels feature is basically what you need to hit it big. On any random spin, the Nitro Reels can put an extra spin on your game by covering 2 positions on the grid. Each reel comes with extra payout symbols: 4, 6, 8, 10 or 12. You’ll know how many symbols have been added because these are literally added to the grid. So if it’s 6 symbols, all of them will appear across positions. Above the game grid is a box that tells you how many ways to win you’re currently playing with. Since each reel can house up to 24 symbols there are 191,102,976 ways to win. Now how about that?
12 bonus features may sound like a lot (and it is) which is why Elk Studios has added a bonus feature reel above the base game grid. On this reel, 8 bonus feature symbols can appear, nudging the reels below so you’ll never lose sight of where you are in the game. Here are the eight features explained:
Both Ways feature: all winning combinations are paid both ways
Winning Respin feature: all symbols and Nitro Reels are locked in position and respin until no more winning combinations are formed.
Nitro Wild feature: Nitro Reels landing in the same column carry wilds
All Premium feature: All Nitro Reels carry high value symbols
All Wild feature: all Nitro Reels carry only wild symbols
Nitro Match feature: Nitro Reels match up with a symbol on the reel to the left
All Match feature: same as the Nitro Match Feature
Nitro Upgrade feature: Nitro Reels that land in the same column upgrade with extra symbols to the Nitro Reels
Bonus Game feature
As if all the Nitro extras weren’t enough, there’s also a bonus game feature. It’s triggered by at least 3 Nitro Wolf police car symbols on the grid. Naturally, more bonus symbols awards you more 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
Nitropolis 2: Slot Review Summary
In terms of gameplay and mechanics, Nitropolis 2 is almost identical to the original Nitropolis slot. Nevertheless, the Nitro Booster features do carry the game forward in an exciting and unpredictable way. And they’re certainly not just game stuffing, but actually add extra variance to the game experience. The ridiculously high number of ways to win brings even more excitement to players wanting to score crazy big wins. So, if you’re into chaotic slots with a punk-rock feel, this one’s for you!
