Nitropolis 5 Review

It's everything you ever wanted from a crazy, far-fetched, revolutionary slot with wacky characters, ingenious features and the potential to win enormous prizes. Be warned, though, this is going to make your brain hurt.

Gameplay & Features

Where do you start with a game like Nitropolis 5? Well, my advice would be Nitropolis 1. Things have progressed through the series with a range of features and add-ons that can seem a little complicated at first. 

The basic idea is that the reels will grow and shrink as you land prizes on the top row and this can lead to millions of ways to win a prize. This stat is aided by the Nitro Reels which produce large clusters of matching symbols that'll come together and sit in one place. 

Basic wins and symbols shown on the Nitro Reels are made up of regular pay symbols which include royals with a max 0.25x win for a group of 6; 4 Clan symbols, which pay 0.3x; and 4 picture symbols with a maximum 3x top payout. 

Symbols need to land on adjacent reels and start on the leftmost reel to form a win. Winning symbols disappear and new ones come into place. As wins occur at the top of the reels, they push upwards and you'll also see the 3 screens move along with them.

Features & Bonuses

The screens show features that you can enjoy during your adventure. One of those is the Boss Battle and to play this game, you'll need 3 Boss Battle coins. You have 3 re-spins and each time a shot hits a number, the respins are renewed. Numbers show multiplier values of your bet total and potentially the max win as well. 

You can also trigger the NPD holding cell where a random symbol is chosen, and if it forms part of a win, those symbols are locked in place and the reels respin. This continues for as long as new symbols help improve the win. There are 11 Nitro Booster features in total and the others include max rows, both-ways wins, symbol upgrades, scatter pay wins, added wilds and more.

You'll need 3+ Bonus symbols to trigger the free spins game and if one is a super symbol, you'll get max rows, both ways wins and an NPD holding cell with each spin. Nitro reels are sticky throughout your free spins.

NPD Holding Cell

One random symbol is selected and if more symbols of that type take part in a win, they lock in place. You can keep building up matching symbols as they fill the holding cells.

Boss Battle

The Boss Battle is a respin feature and your 3 spins are reset each time a shot hits the target. You'll pick up values which are multipliers of your bet amount.

Nitropolis 5 - Nitro Reels & Boosters

Nitro Reels & Boosters

Nitro Reels produce multiple numbers of matching symbols to help improve your winning chances. There are 11 booster features that can modify these reels and bring big wins

Nitropolis 5 - Bonus Game

Bonus Game

You'll need at least 3 Bonus symbols to trigger free spins and with a super symbol, you get extra benefits. Watch out for an NPD Holding Cell with each spin and Nitro Reels are sticky throughout.

Win Potential

Firstly, the volatility level isn't as high as you might expect for a game with a 50,000x max win (8/10). Some players outside the UK will have access to the X-iter menu and this might help produce bigger wins, but they come at a cost. The Bonus Hunt plays out for 3x and gives you a better chance of triggering the bonus game while Nitro Boost costs 10x and you get a spin with a Nitro Booster full of features. 25x will guarantee the triggering of the NPD Holding Cell and 100x takes you straight to the bonus game. 500x produces the super bonus game. 

To get a feel for the super bonus game, I used the buy-in option to see exactly what these super 8 free spins would produce. It began with max rows and both way pays as my 2 main features and this quickly started pushing my bankroll higher and higher. After that, the wins started to dry up a bit but I did see the Holding Cell appear and some Nitro Reel upgrades as well. Unfortunately, I only walked away with a 145x win, which is nowhere close to the 500x buy-in figure! But, you can't expect top returns every time and regardless of the win size, the entertainment factor was there. It took at least 5 minutes to complete the bonus game!

Design

There's an incredible array of design elements coming together to make Nitropolis 5 quite the spectacle. It takes a while to get your head around how these reels move and you've got to admire the techniques that have been employed to add such intricate visual features. I don't want to spoil it for you by explaining everything that you're going to see - I think it's best just to watch it load before your eyes and try and take it all in. It looks just as fantastic on a mobile screen, so iGamers who like to have a few spins while out and about can also enjoy this crazy creation.

Our Verdict

There's a lot here to remind you of the series that has gone before and if you enjoyed the mini-series that goes between Nitropolis 4 and Nitropolis 5, then you'll also have a better affiliation with the characters as well. You can try out titles such as Rogue Rats or Gritty Kitty if you'd like to relive some of the magic or get to know them even better. The max 50,000x win is substantial and when you see this astonishing range of features start linking together, it's not hard to imagine that one day, somebody's spins are going to trigger something quite special.
