Nitropolis from ELK Studios has got between 4,096 and 85,155,840 win ways! With a max win of 10,000x plus loads of fascinating features, this animal dystopian future surely can’t be all that bad.
The game area is 6x4 in size with a default 4,096 win ways. To win, you need to land matching symbols on adjacent reels, starting from the first reel. Be on the lookout for Nitro Reels. These are symbols which cover two vertical positions but they can contain between 4 and 12 instances of the same symbol, which greatly increases the number of win ways. In fact, you could theoretically see a maximum of 85,155,840 ways to win.
Jack to Ace are the low pays. A 6-of-a-kind can be worth up to 0.5x the bet. The mid-pay symbols are the main characters’ different badges. Land a 6-of-a-kind and you can win up to 1.6x. The high pays are the main characters themselves. 6 of the same symbol is worth up to 5x. Wilds substitute for all pay symbols.
When you land a winning combination, its positions on the grid will respin, thereby allowing for more potential wins. The same goes for any Nitro Reels that form part of a win. In fact, on a respin, its number of symbols can randomly increase, too. This Winning Respins function continues until there are no more wins. Sometimes, even if a Nitro Reel doesn’t form part of a win, it might grant a Second Chance Respin.
3, 4, 5 or 6 scatters triggers 10, 15, 20 and 25 free spins respectively. A random pay symbol is selected to be a Scatter Pay symbol, meaning instances of that symbol will pay out regardless of where they are positioned on the grid. In Free Spins, all Nitro Reels lock into place and remain there until the end of the round. The round can be retriggered by landing further scatters.
Thanks to the Nitro Reels you could potentially see up to 85,155,840 win ways. That along with the Winning Respins functions means there’s always plenty going on in the base game.
You only need 3 scatters to trigger Free Spins, and said scatters seem to fall quite frequently, so you probably won’t have to spin for ages in order to trigger it. The round itself should present players with plenty of chances to win big. 10 is the minimum number of free spins, Nitro Reels stick to the grid and you can potentially retrigger the round.
These symbols cover two positions but can contain up to 12 instances of the same symbol. If part of a win, they will respin, giving you a chance to win again. The number of symbols they contain might randomly increase, too.
All winning combination symbols respin, granting players another opportunity to hit wins. Winning Respins continues until there are no more wins.
3, 4, 5 or 6 scatters grant 10, 15, 20 and 25 free spins respectively. 1 symbol functions as a scatter-pay symbol. All Nitro Reels stick to the grid until the end of the round.
The game’s theoretical RTP is 96.1%, and its mathematical model is highly volatile. It does play in keeping with these stats; however, thanks to the breadth of features, there’s always a lot going on, so you might get the impression that it’s a lower-volatility game.
Again, thanks to the features, you can see up to 85,155,840 win ways - mind-boggling. The Winning Respins and Nitro Reels mean there’s big-win potential even in the base game. In Free Spins, there’s the addition of Sticky Nitro Reels and scatter-pay symbols, which can again, really increase your win potential. It makes it look like someone could actually be lucky enough to walk away with the 10,000x max win.
The game’s setting is a dystopian metropolis and the 6x4 game area is a Mad-Maxian mesh of metal, cables and tubes. To the left and the right, you can make out a smoggy cityscape on an otherwise clear day. It’s like Sonic the Hedgehog for adults.
The layout is decent. There are plenty of interesting features but nothing gets confusing. In particular, I like how you can clearly see the number of win ways and the number of symbols within the Nitro Reels. The game also looks great on both mobile and desktop.
Graphically, this is a fairly standard slot. The highlight is the artwork of the cityscape in the background. The design of the symbols and the reel animations seem a little flat though. The tech house playing with motivational slogans over the top is great, too.
I thoroughly enjoyed playing ELK Studios’ Nitropolis - partly because the base game is just as engaging as the free spins round. Its interesting features make it really fun to play, and the high volatility means there’s plenty of occasional big win potential.
