Nitropolis 2

Return for more nitro-fuelled reel mayhem on Nitropolis 2 from Elk Studios. Sergeant Nitro Wolf is cracking down on the gangland metropolis, has locked up the Rouge Rats, and is coming for the remaining Dirty Dawgs, Gritty Kitty and Pug Thugs gangs.

In this episode, the Nitro Reels link with Nitro Boosters appearing in an extra reel at the top to trigger upgrades, both-ways pays, winning respins, wilds and more. Plus, a bonus game with locked Nitro Reels can lead to wins of up to 10,000 times your bet.

Slot Details

Nitropolis 2 is a video slot with six reels, four rows plus an additional top reel, The Nitro Booster. There are 4096 ways to win that can increase to a whopping 191,102,976 ways. Join Sgt. Wolf on desktop, tablet or mobile from 0.20 to 100 credits per spin. Nitropolis 2 has a hit frequency of 20 %, a volatility rating of 8 out of 10 and an RTP of 95%. You can also bonus buy a choice of five different scenarios with Elk Studio’s X-iter feature.

Simply put, as far as video slots go, Nitropolis 2 is a work of art. It looks and sounds fantastic. Sirens and police radio chat compliment the funky guitar riff of the soundtrack. And a dark, dystopian city backdrop lit up with futuristic advertising boards provides the setting. Clever scripts like ‘Step out of the vehicle and place your hands on the trunk’ grace explosive big win animations in a blockbusting presentation.

The pay symbols start at the low end with card royals from J through to A, awarding 0.4x your bet, across the board for a single six of a kind. They are followed by the three gangs; The Pug Thugs in green, The Gritty Kitties in pink and The Dirty Dawgs in red plus the introduction of The Pest Control symbol in gold for the mediums. Six across the reels will yield 0.5x your stake. The premiums are the remaining symbols – the pug, kitty and dog in their gangs matching colours in addition to Sergeant Nitro Wolf in gold. Six on a bet way will pay 0.7x to 1x your bet.

In a comical twist, the wild symbol is a ‘no fouling’ sign that substitutes for all symbols except the bonus and is worth 1x your stake for six. The Sergeants car acts as the bonus scatter and can appear on Nitro Reels or Nitro Booster, counting as a single scatter only. The Nitro Booster has 8 unique feature symbols of green and gold plus bonus symbols.

Nitropolis 2 Slot Features

Elk Studios never fail to impress visually with Nitropolis and Nitropolis 2 being some of their best creations in that respect, although the chaotic mechanics could be mind-blowing for some new players. Even regulars could be somewhat confused, so let’s try and make sense of the mayhem-filled reel fun.

Nitropolis 2 plays similar to the first with each win, during both the base game and free spins, triggering the Winning Respins feature. All symbols, the Nitro Reels plus this time the Nitro Boosters, that are part of that win, will respin and repeat the process providing more wins appear. Any Nitro Booster features landing will stick to the reel, while the spaces that remain in play respin in sequence. All reels and boosters reset at the end of a spin sequence and the accumulated win paid.

In keeping with the original, the Nitro Reels work the same way, covering two vertical positions upon landing. They can create a mind-blowing 191,102,976 more ways to win by unveiling 4, 6, 8, 10 or 12 identical symbols. The symbols may not match for each Nitro Reel, which numbers its current value above, organising a watchable method to the madness.

The Nitro Booster is a top reel that can bring features to the main reels. Green Nitro Boosters affect the Nitro Reels in the same column, Gold Nitro Boosters affect all Nitro Reels across the reels and Blue, named Respin or Pay Both Ways, do as their titles suggest. A bonus symbol can also appear and each green or gold booster has a unique feature as listed below.

Green Nitro Features:

• Nitro Wild: Nitro Reels below will contain wilds.
• Nitro Upgrade: Upgrades the Nitro Reels increasing the symbol amount.
• Nitro Match: Nitro Reels match up with a symbol on the reel to their left.

Gold ‘All’ Nitro Features:

• All Premium: Premium symbols only feature in all Nitro Reels.
• All Wild: All Nitro Reels already in play or landing will contain wilds.
• All Match: All Nitro Reels will match up with a symbol on their left.

The Winning Respins, the Nitro Reels and Nitro Booster also feature during the bonus round. Landing 3, 4, 5 or 6 scatters will trigger 10, 15, 20 and 25 free spins, respectively. Any Nitro Reels landing will lock in place for all remaining free spins. Free spins can also be retriggered using the same combinations.

Elk Studios’ X-iter feature offers a choice of five spin scenarios at a premium bet amount, from modified reels to super bonuses and more. Options are displayed on X-iter buttons naming the feature or listing a number and a spin symbol for batches of spins, individually tailored for each release. Nitropolis 2 X-iter offers win spins and bonuses:

• 100% Trophy Guaranteed Winning Spin | 5x Bet: A standard spin on Nitropolis 2 with a guaranteed win.
• Max Nitro Booster – 3 spins | 25x Bet: Guaranteed full to the brim Nitro Booster with Nitro Features or bonus symbols for three spins.
• Buy Bonus | 100x Bet: A straight three scatter trigger for at least 10 free spins bonus round.
• Big Bonus | 200x Bet: A four scatter trigger for at least 15 free spins of the bonus round.
• Super Bonus | 500x Bet: A 5 scatter trigger spin starting at least 20 free spins with a twist, for this bonus round starts with the full possible twelve Nitro Reels in play.

Each X-iter bonus starts as a standard spin with its guaranteed number of scatters meaning a chance of additional scatters as the qualifying spin plays out.

Final Verdict

The Nitro Booster introduction on Nitropolis 2 separates it sufficiently from its older sibling and makes it unique enough to stand on its own. It’s much more than just a run-of-the-mill follow-up. It’s a beautifully crafted release, in that unique Elk way with some neatly linked feature mechanics and an epic soundtrack. Not for the faint-hearted but, if it performs as good as it looks, Nitropolis 2 could be a slot of the year contender for some.

Nitropolis 2 – Frequently Asked Questions (FAQ)

1. Can I bonus buy a feature on Nitropolis 2?

Yes, in a nice change from the standard bonus buy, X-iter allows the purchase of five different scenarios for Nitropolis 2. These range from five times your bet for a guaranteed win spin, through to a 500x Super Bonus feature with 12 Nitro Reels in play. The RTP remains the same at 95%. X-iter features on some of the more recent releases from Elk Studios such as Cluster Slide and Bompers.

2. Is Nitropolis 2 difficult to play or understand?

Though Nitropolis 2 is action-packed, the in-game information helps with understanding. There is never a dull moment and following a few spins, the mechanics start to make more sense.

3. Is a 20% hit rate reasonable?

Hit rates are a guide and nothing more. They are calculated over millions, or in more recent times, billions of spins. While 20% would suggest 1 win in every 5 spins, this should never be expected to happen in every session. Slots can have longer periods of losing spins followed by occasional winning streaks.

4. Can I land 3 scatters during an X-iter Win Spin on Nitropolis 2?

Yes, all X-iter scenarios are played directly from the game and work the same way unless otherwise stated.
