The medium paying symbols are the clan badges which can pay between 1.2 to 1.6x for 6 on a pay line.

starHow to trigger Big Wins in Nitropolis?

  • Wild Symbol

The game’s wild symbol is an image of a bomb with the word ‘Wild’ in it. It can substitute for all pay symbols in order to create more winning combinations. The wild symbol can’t substitute for the scatter symbol.

  • Nitro Reels

Nitro Reels cover two symbol places and can hold several identical symbols – from 4 up to 12. A Nitro Reel can randomly upgrade and represent a higher number of matching symbols, which can create even more ways to win. It could also randomly respin after a non-winning spin, giving them another chance of a win. 

In the bonus game, all Nitro reels stay in place for the remaining free spins.

  • Winning Respin

Every time you land a win, the winning symbols and Nitro Reels will then respin. This can keep continuing until there are no more winning combinations made.


Nitropolis (ELK Studios) Slot Review - 💎AboutSlots

starHere's how you win 25 free spins

In Nitropolis 1 the free spins bonus game is triggered by landing the scatter symbols. If you get 3, 4, 5 or 6 scatters anywhere on the reels then you can earn 10, 15, 20 or 25 free spins respectively.

During this bonus game, you can retrigger the free spins in the same way in which they were initially triggered. As soon as the bonus round begins, there are other features you can take advantage of. All of the Nitro Reels become sticky and will be locked into place until the end of the round.

Also, a random pay symbol will be designated as scatter wins – whilst still paying out standard wins as well. Here, you will hit a win if 3 or more scatters land on different reels. If you get 3 or more scatters, you will also retrigger the free spins.

starNitropolis Vs Nitropolis 2: What's so different by ELK studios?

Nitropolis 1 has the highest RTP ratio of 96% in the trio and it is considered to be highly volatile, so you better expect a long gap between your wins. However, the maximum ways to win goes only up to 85,155,840, which is almost half of what you get in the Nitropolis 2 or Nitropolis 3 that came in later.

Nitropolis is a great game by ELK studios and worth every minute spent playing it.

starThe Verdict

Nitropolis is a very solid game that starts off the story of the post-apocalyptic dystopian world excellently. The game offers free spins – and a way to buy your way into the bonus spins if you don’t fancy waiting. The graphics are slick and the gameplay is superb – with big reels all making way for some big wins. 

This online slot machine can offer plenty of excitement as you play. It starts off with an incredible 4,096 ways to win but can increase to an incredible 85,155, 840 ways to win with a little help from the Nitro Reels. The free spins bonus game can be hugely rewarding – and if you land those right combinations, you can win up to an astonishing 10,000x your bet!
