With Nitropolis 4 online slot, you will get a 5-star audiovisual experience. But can we say the same for the gameplay? Answering this question is possible only after analyzing the key game features.
Thanks to this detailed Nitropolis 4 slot review, you will better understand the slot’s story, grid and winning ways, special features, and a few other things. Like all our slot game reviews, no stone will be left unturned when analyzing Nitropolis 4.
Theme – Post-apocalyptic
Dystopian and post-apocalyptic themes are pretty popular in modern movies and books. Thanks to some software developers, including ELK Studios, stories like this are added to many slots. So, the Nitropolis 4 slot is a post-apocalyptic-themed game.
It seems that something has happened to humanity, and animals have taken over the control of our planet. They have developed human characteristics (or maybe they were mixed with humans, who knows?) and started running things, including working at docks.
One of the ways to figure out what the theme is all about is to check the standard symbols. In addition to the four classic playing cards, this slot has eight other standard icons: team emblems (Rogue Rats, Pug Thugs, Gritty Kitty, and Dirty Dawgs) and four animals that lead these teams (a Rat, a Pug, a Cat, and a Dog).
The special icons, like the Naval Mine Wild icon or the Nitro Canister Multiplier icon, also support the theme.
Reels
Even though the gameboard at the Nitropolis 4 online slot is not fixed, the number of reels is always the same – 6. As for the rows, the grid can display 4 to 8 rows per reel.
Paylines
This is another example of an online slot that doesn’t use conventional paylines. The Nitropolis 4 slot offers at least 4,096 ways to win, and the game states that this number can reach millions in some situations.
In any case, hitting winning patterns is always the same – you need three to six standard symbols of the same kind on adjacent reels starting from reel 1.
RTP
We’ll continue our analysis of the key game features with the theoretical Return to Player percentage, or simply RTP. Learning this percentage will help you understand what you can expect regarding payout rates in the long run. This is a theoretical prediction.
The Nitropolis 4 RTP is 94%. So, it’s on the lower end of the average range. Still, this doesn’t mean you can’t play the same game with a higher payout rate. Namely, many online casinos alter these rates according to their specific needs. We have a table below to prove that.
It’s important not to focus only on the sheer numbers. You should also check the reviews for these casinos. Our reviews include essential information about the casino welcome bonuses and deals, banking options, game variety, customer support, and other things that will help you decide where to play Nitropolis 4.
Of course, there are other slot sites we recommend, not just the ones on the table above. These are carefully hand-picked casino sites with excellent offers for UK players.
Stake Range
This time, we have twelve wagering options. The Nitropolis 4 slot lets you wager as little as £0.2 per spin and as much as £50 per round.
Max Win
Another great thing about this title is the maximum win cap. This is a rare example when this value is set at 50,000x the total bet.
Big Symbols
At random, Super or Mega symbols covering 2x2 or 3x3 positions can appear on the matrix. They are known as Big symbols. Remember that both standard and Wild symbols can occur in this form.
While discussing the Wilds, we should note that they appear like Naval Mines and replace standard symbols to finish winning combinations.
Avalanche Feature
When players hit a winning combo, they will receive a prize. Before they get a chance to spin the reels again, they’ll witness the removal of the contributing icons. This will make new symbols drop from above and open an additional row. As we said, you can get up to 8 rows per reel.
Nitro Booster
There are two monitors above the grid at the start of each round. These monitors are typically blank, but at random, they can reveal so-called Nitro Booster modifiers. A total of 8 special modifiers can appear in these areas.
The modifiers offer various extras: Redrop (a partial respin), layout expansion, both-ways payouts, an extra Nitro Reel, a Nitro Match for a winning combo, a Nitro Reel’s value improvement, or a Wild Nitro Reel.
Nitro Reels/Nitro Multiplier
Nitro Reels occupying two grid cells can appear randomly on any spin. We’re talking about special reels boasting four to twelve regular symbols. Additionally, there are Big Nitro Reels with 6 cells featuring two to six 2x2 standard icons.
Besides that, you can hit Nitro Multipliers. Like the Nitro Reels, they cover two cells and are a single symbol. Of course, they are here to help you boost your wins by multiplying these wins. You should expect values of x4 to x12, which will be multiplied together if there’s more than one on the gameboard.
Bonus Game/Free Spins
The good news is that you’ll find a bonus game too. It’s basically a round of free spins launched whenever you get three to six Bonus icons (Hand-cranked Submarines) on any position on the matrix.
Every player can trigger 8 to 20 free spins, during which the Nitro Reels stay in their place (Sticky) until the round is over. With every winning turn, the safety level is increased by one row.
In addition, there’s a Super Bonus icon, and landing at least three Bonus and Super Bonus icons will activate the Super Bonus Game. The difference is that the higher number of rows is launched at the start, and you can hit winning combinations in both ways.
Jackpot
If there’s one thing that this game is missing, that’s a direct jackpot reward. Still, you should not forget that the max win limit is 50,000x the total stake.
Also, we have a best jackpot slot games page if you really need to play a

Play Experience & First Impressions
Flashy – that’s the word that kept crossing my mind when I played the Nitropolis 4 slot. The 100-spin test I took was fun, but the reels that kept changing with (almost) every spin, the intense music, and the special sound effects were overwhelming at times.
Still, I guess that’s expected from a game based on nitro fuel. The wins didn’t frequently occur even though the modifiers were activated on every third or fourth spin. Thanks to the modifiers, some wins were pretty memorable, especially when the multipliers were involved.
I didn’t start a round of free spins, so I can’t really talk about this experience. Of course, I can’t be satisfied with the final result – an RTP of 70.4% - but the gameplay was exciting. I can give ELK Studios that.
