How to win on Nitropolis 5

If you are a loyal fan of the Nitropolis slots by Elk Studios you already know they are highly volatile slots and it’s incredibly hard to hit those mega payouts while playing them. The same applies to Nitropolis 5. The game is highly volatile, so you need a big bankroll to have a chance at hitting a big win. The best way to do it is via the X-iter option, by buying the Super Bonus. But it costs 500x to buy it and most of the time you get 2-300x in return. So you need a bigger bankroll to have enough to buy the super bonus at least 2-3 times. In one feature with luck on your side you can hit a mega payout and walk away with a small fortune on your account. However it’s also risky playing this way and you can lose all.

Up to 50,000x maximum payout

I’m sure you already know that the Nitropolis slots come with a high payout limit. In the case of Nitropolis 5, the maximum payout sits at 50,000x. This means that if you are playing on the maximum bet per spin you stand to win up to $2.5 million. All players will agree this is a life-changing amount and you would be ecstatic to see it on your screen.

Nitropolis 5 Reels, Rows and 4096 ways to win

For Nitropolis 5 the designers decided to go with 6 reels and 4 initial rows. This means that there are 4096 ways to win initially. But with the Nitro Reels and the max rows features you can get to millions of ways to win. The game also has a Both Ways Pay feature, meaning that wins can be formed from left to right and right to left. This detail makes the game more exciting and payouts easier to land.

Theme, Visuals and Sounds

The game follows the battles of the Nitro Gang. The action takes place in the city of Nitropolis where the final battle is on the way. The villain of the game is Sergeant Nitro Wolf and the gang is making one last push against him. As with all Nitropolis slots, this one also comes with great visuals and animations. The sounds perfectly flow with the theme, resulting in a great slot.

Symbols and Payouts in the Nitropolis 5 slot

Symbol Paytable (shown in the image below)

The lowest payouts in Nitropolis 5 come from the J, Q, K and A symbols. They all award the same payouts from 0.10x up to 0.25x. The medium-paying symbols are the logos from the previous sequels Rogue Rats, Pug Thugs, Gritty Kitty and Dirty Dawgs. They award payouts from 0.15x up to 0.30x. The medium payouts continue with the Rat, Pug and Cat symbols, with 1x, 1.25x and 1.5x. The top paying symbol is Sergeant Nitro Wolf himself, with a maximum win of 3x for 6-of-a-kind wins.

Nitro Reels, Multipliers and Boosters

In terms of features, there’s a lot to cover in the game. Starting off are the Nitro Reels. They can cover up to 2 positions on the screen and contain from 4 to 12 matching symbols per reel. If a big nitro reel lands it covers 6 positions on the reels and contains up to 6 matching 2×2 symbols.

If the nitro reel comes with a super bonus symbol it counts as a single symbol. The Wild replaces all other symbols, except for the bonus and super bonus symbols. All of the regular symbols, including the Wild, can come as a 1×1, 2×2 and 3×3 symbols.

You can also land a Nitro Multiplier in a nitro reel which can be anywhere from 4x up to 12x. It will multiply all the wins it contributes to and count as a single symbol. All of the winning symbols are removed and the rest fall down. With each drop, an extra row is added to the reels, up to a maximum of 8.

NPD Holding Cell

On any spin, you can randomly trigger the NPD Holding cell feature. One symbol type is randomly chosen. If the symbol is part of a win all of those symbols are locked and kept on the reels, along with any bonus and nitro multiplier symbols. You get a re-spin which increases the number of rows and a chance to land more locked symbols. This continues until no more symbols can become locked.

Nitro Booster

There are 11 Nitro Boosters that you can trigger on the reels. Six of them are for the main reels and 5 of them are for the nitro reels. For the main reels, you can get the Max Rows, Dirty Dawgs, Gritty Kitty, Respin, Both Ways and Boss Battle.

During the free spins bonus, the nitro reels are kept on the screen for the entire feature. The super bonus is played on the maximum 8 rows with the both ways feature active. At the same time, the NPD Holding Cell feature is activated on every spin.

Results from our 500 spins on Nitropolis 5

Elk Studios is one of our favourite providers, so we’re always excited to try a new game from their portfolio. With Nitropolis 5 we were especially excited since these are our favourite slots from this provider. In our regular 500 spins, we managed to trigger the bonus round only twice, with disappointing results. The first feature only paid 56x, while the second came in at 96x.

So after the 500 spins were done we gave the bonus buys a try. We instantly went for the super bonus, where the first buy gave us a return of 287x. This was not enough to cover the cost, so we bought it again. This time the payout was bigger at 723x, but again the two buys combined only left us with 10x profit. The third buy was also better at 784x, so generally we were happy with the returns.
