starHow to play Nitropolis 2?

Just as with the first instalment, the Nitropolis 2 slot game is played on 6-reels and 4-rows and offers over 4,096 winning ways, with an average RTP of 95% and a hit rate of 20%.

As you enter the base game, in order to hit a win, you need to land 3 or more identical symbols on any active pay line from the leftmost reel (unless you land both ways symbol, in which case it pays both ways). There are three levels of symbols.

The lower-paying symbols, represented by playing cards, payout a maximum of 0.4x your bet for 6 on a pay line. The patrol badges are the mid-paying symbols and these payout up to 0.5x your bet for 6 on a pay line. The higher paying symbols are the clan leaders – with Sergeant Nitro Wolf leading the way, with up to 3x your bet for 6 on a pay line.

starHow to trigger Big Wins in Nitropolis 2?

  • Wild Symbol

The wild symbol can substitute for all other standard pay symbols, helping to create winning combinations. It cannot substitute for the scatter symbol.

  • Nitro Reels

This symbol will always cover 2 positions on whichever reel it lands in. Above it, there will always be a number – 4, 6, 8, 10 or 12. This will determine how many of the payout symbols displayed the Nitro Reel contains.\

  • Winning Respin

Whenever you land a winning combination, all the triggering symbols and Nitro Reels will then respin. This continues as long as there are new winning combinations being created.

  • Nitro Booster

Above all of the reels, 8 different Nitro Boosters can randomly land, each with different features – all of which have the potential to massively boost your winnings. These are the 8 possible Nitro Boosts:

  • Respin: All of the Nitro Reels and scatter symbols will remain locked into place and then you are given a free respin.
  • Both Ways: Landing this will mean wins payout left to right and right to left also.
  • Nitro Wild: If you land a Nitro Reel underneath this symbol, the reel will show wilds.
  • All Wild: If this is triggered, all new and sticky Nitro Reels will contain wild symbols.
  • Nitro Match: If a Nitro Reel lands under this, then its symbols will be matched with the symbols on the reel to its left.
  • All Match: This matches all Nitro Reels with the symbols on the reel to its left.
  • Nitro Upgrade: If a Nitro Reel lands underneath this symbol, the number of symbols in the Nitro Reel will increase.
  • All Premium: This symbol will mean that any Nitro Reel that lands will contain only high-paying symbols.
  • X-iter

This feature means that you can guarantee certain other features by paying more of your wager. It works as follows:

  • For 5x your bet you can guarantee a winning spin.
  • For 25x your bet you can get 3 spins that are guaranteed to land either a bonus or feature symbols on all positions on the Nitro Booster.
  • For 100x your bet you can buy your way into the bonus game with 10 free spins.
  • For 200x your bet you can buy your way into the bonus game with 15 free spins.
  • For 500x your bet you can buy your way into the bonus game with 10 free spins and start with the maximum of 12 Nitro Reels


Nitropolis 2 (ELK Studios) Slot Review - 💎AboutSlots


Nitropolis 2: the NITRO RELOADED SEQUEL | Mr Green

starNitropolis 2: What's new by ELK Studios

Nitropolis 2 has a new feature reel called the Nitro Booster which runs on the top of the main grid and lands to feature symbols to modify the reels beneath it.

ELK Studios reduced the RTP ratio of the sequel to 95%, but the maximum number of win ways is significantly increased to 191,102,976 from nitropolis 1. Also, you won’t see the Rouge Rats clan as they got locked up by Sergeant Nitro Wolf to clean up the Nitropolis city, adds ELK Studios.

starFree Spins Bonus

If you land 3 or more scatter symbols, you will trigger the bonus free spins round. Landing 3, 4, 5 or 6 scatters will award you 10, 15, 20 or 25 free spins respectively. These can also be retriggered during the round. During the bonus round, all Nitro Reels are sticky and will remain in place for the entire round.

starThe Verdict

This sequel slot game combines plenty of features – that you can either land or buy your way into if you don’t have the patience to wait. It is very similar to the previous instalment of the game, with seamless gameplay and slick animations and graphics that light up the reels. It isn’t easy to create a good sequel, but Elk has handled the challenge phenomenally.

This is certainly a high volatility slot – so, if you are a player looking for more frequent wins, then this might not be your game. It can take some time before any of the bigger wins start coming in – as well as managing to land the right number of scatters – which will activate the bonus round.

This is where the biggest wins can be found. When this happens, you really are in for a treat. And make sure you are playing only at UK casinos with fast withdrawals, so the big cash gets into your account quickly. This game may start out at 4,096 ways to win – but if you unlock the maximum 191,102,976 ways to win, things really start to get interesting.
