Nitropolis 4 Slot Review
Online slot providers are stepping up their game with the recent advancements of video slots that include some additional features besides just the free spins or bonus rounds. One such provider is Elk Studios, and while we’ve seen the previous potential of their slots, the Nitropolis 4 slot seems to be on the whole other level.
After the decent success of the previous Nitropolis slots, the dog crew is back again with the latest adventure. With a payout potential of up to x50,000 of your base bet, we think this game deserves at least the equal attention that games like Money Train and Reactoonz received, so let’s see what this slot offers in more detail!

About the Game
Before we get into the game features and bonuses, it’s time to discuss some basics about the Nitropolis 4 slot. As you can see as soon as you load the game, there’s a new background that seems as if the crew is digging resources within an underwater bunker.
The slot has a great visual appeal to it, and the graphics have been significantly improved for this release when compared with previous versions. What we liked the most about the game is the unique slot grid which isn’t your ordinary 5×3 layout.
Instead, the game uses a 6×4 slot grid and it’s even possible to see the grid expanding within the base game and the bonus round. So, it can grow to an admirable six-reel and eight rows layout, and this makes it even more exciting.
You can see numerous in-game features that we’ll discuss in detail, but it’s important to mention colossal symbols that appear as 2×2 or 3×3 blocks, multipliers, and nitro features.
The game initially comes with 4096 winning ways, but that can be expanded to over 250,000 winning ways, which is more than you get with Megaways™ slots.
The Nitropolis 4 slots come with a max win potential of up to x50,000 of your base bet. This places it rather high among online slots, right beside the Money Train II, Hammer of Vulcan, and Mystery Museum.
You can expect to have a lower hit frequency because of that since this slot fits in the category of high-volatility games. We think it’s a trade that you as a player would probably be willing to make every day of the week due to a chance to get massive wins.
On top of that, the RTP is 94%, which is rather low for an online slot. Then again, it’s that volatility that makes it this great. It means you can get stellar wins even on penny bets, making it a perfect low-roller slot.
Nitropolis 4 Symbols and Payouts
Our final stop before game features and bonuses is the description of game symbols and the payouts you can expect. There’s a wild symbol that substitutes for all existing symbols in winning combinations except for the bonus symbol.
So, you’ll be looking to hit as many of these as possible to unlock the true potential with 4096 winning ways. Because of so many win ways, the payouts for a five-of-a-kind win (or rather six-of-a-kind in this game) for a full line can be seemingly low.
For instance, you have low-value symbols like letters A, K, Q, and J that only pay x0.3 of your bet. Of course, you can hit nearly a full screen of these, so that’s where the win ways step in.
As for the premiums, you will first have middle-value symbols like “Pug Thugs” and “Rogue Rats” that pay x0.8 of your bet. The “Dirty Dawgs” and “Gritty Kitty” symbols pay x1, and the high-valued premiums like dogs and rat symbols pay x1.25, x1.5, x2, and x3 of your bet for a full-line hit. The red dog symbol is the premium in this game and this one is the most valuable in winning combinations.
Nitropolis 4 Bonus-Buy Features
Like all the high-value modern slots, this game also brings you the chance to buy your way into the bonus rounds. Sure, some players enjoy hunting for the bonus, and that’s why Elk integrated a bonus hunt feature which doubles your chances of landing the bonus.
Of course, your bet level will be higher because of this, and you can also use the Super Spin feature for a cost of x25 of your bet. Once you trigger this spin, two of the game’s features activate – Max Rows and Both Ways. So, the payouts will be calculated both from left to right and from right to left with a total of 8 rows.
If you are lucky enough, you can get the max win of x50,000 of your bet for a mere price of x25 of the bet. Moving on, you also have bonus-buy options that take x100 of your bet to buy the regular bonus round, and x500 of the bet for a Super Bonus.
Main Game Features
It’s enough going on and on about the game – let’s give you the perspective on the main features you may expect out of the Nitropolis 4 slot. This game is an action-packed video slot and that’s what we enjoyed pretty much during the play.
Here’s an overview of the most significant base-game features:
- Symbols tumbling
- Colossal symbols
- Nitro Reels
- Nitro Boosters
We know this sounds like a lot, and to be completely honest – it is. While it’s a great thing to have so many base game features at your disposal, it makes the game more difficult to understand at first.
Even so, don’t we play online slots for the fun of the innovative game features? If that’s the case with you, we first have to point out the tumbling mechanics. Every connection made of matching symbols on at latest three reels will result in new symbols dropping in to replace the previous ones.
That’s where the Nitro Reels and Colossal symbols come into play – these can increase your winning chances. With big symbols, you get larger winning clusters, and with Nitro Reels, you get two or more symbols merged into one and they show the matching symbol.
While multipliers often are connected with the Nitro Reel, these can award you with an x2 to x12 multiplier of the prize. Finally, Nitro Boosters are there to make the game even more engaging.
Nitro Boosters are perhaps the most exciting features of the game since you never know what to expect out of each spin. These boosters appear above the grid and there’s room for two boosters within a single spin.
We’ve already discussed how Both Ways and Max Rows work on the example of the Super Spin feature. However, you can also get various other features, including the following:
- Re-drop feature – This feature eliminates all the symbols on the grid except for the Nitro Reels and new symbols are dropped to increase the chance of forming winning combos.
- Nitro Match feature – This one is pretty exciting in clutch situations where it seems to be no more possible combinations. In this case, the Nitro Match may transform the adjacent symbol to match the symbol displayed within Nitro Reels.
- Garbage collect feature – Much like the re-drop feature, Garbage collect appears to disintegrate certain symbols and drop new ones in their place.
- Nitro Wild feature – Another exciting base-game feature is the Nitro Wild action which replaces the symbols within Nitro Reels with wilds for a higher potential of forming winning combinations.
- Nitro Upgrade feature – The upgrade feature of the Nitro Reels enhances their value and therefore boosts your payout potential in that specific spin.
- Nitro Appear feature – This is when the Nitro Reels symbol gets added to the screen when you expect it the least and it can sometimes lead to more features.
As you can probably guess, the game also has bonus rounds and there are two main types of these – the regular bonus, and the Super Bonus feature. The regular bonus starts when you land at least 3 bonus symbols to activate 8 free spins.
Of course, having in mind that there are six reels in this game, you can also land up to six bonus symbols to initiate a 20-spin bonus round. The more bonus symbols you land, the higher the count of bonus spins will be.
It’s also worth stating that all the Nitro Reels remain locked in place during the bonus round, which increases your winning chances. You can even win 5 or 6 Nitro Reels to make every spin a winning one, and the Super Bonus extends the rows up to 8 with the Max Rows and Both Ways features.
You can buy a bonus round and that will automatically land at least 3 scatters, but keep in mind that buying a Super Bonus can cost you x500 of your base bet.
Our Take On Nitropolis 4 Slot
Overall, we have to applaud Elk Studios for stepping up their game with this recent release. The Nitropolis 4 slot makes one of the most engaging new slot games for online players, and with all the features it has in store, you are always destined to have a lot of fun.
Of course, the x50,000 winning cap is something to discuss as well, since it brings an impressive winning potential to the table. In the end, it’s only left for us to rate the slot, and we give it 5 out of 5 on our slot rating scale for all the innovative options it delivers, as well as impeccable graphics.
