Game Overview
What did you say? A futuristic city that’s inhabited by animals? That sounds like something straight out of a Spielberg movie script! But if that’s what you were thinking, like me, you’d be completely wrong. Instead, it’s the setting for ELK Studio’s slot titled Nitropolis 3, which, yes, you guessed it, is the third game in this series of slots. So, how are the stats shaping up in this one? We’ve got 4,096 fixed paylines in play, a slightly below average RTP of 95%, and a whopping maximum win of 50,000x bet.
Fans of hi-tech slots will be pleased to see that this game is bustling with features from start to finish. These kick off with the avalanche reels that can help create multiple wins from just one paid spin. These also work in unison with the Nitro Reels mechanic, which has three separate modifiers that can further increase your chances of winning. The biggest and best bonus within the game, however, is the free spins feature, activated when at least three scatters appear in view. During this round, the game will pay from both ways, with all nitro reels remaining sticky throughout. To top things off, the unique X-iter feature also allows you to activate some aspects of the game for an additional cost.
How does this slot shape up to the games that came before it? There’s only one way to find out: by reading our full review and trying out some practice spins on the free demo slot of Nitropolis 3 below.
Nitropolis 3 Slot Theme, Stakes, Pays & Symbols
Let’s be honest; animals are no strangers to featuring in online slots, although if you were put on the spot, you’d probably reel off mainly safari themed slots unless you gave yourself a little time to think. But this time, you’re going to be in for a surprise; there’s not one hint of the Serengeti or a rhino in sight; instead, dogs are ruling this futuristic world. Maybe you’re getting Planet of the Apes type of vibes now or imagining a theme similar to the Infectious 5 slot created by Nolimit City. That would be incorrect, though, Nitropolis has its own very unique theme and setting, and with two successful titles already in the bank in this series from ELK Studios, we’re set to take a look at Nitropolis 3 today to see what added extras have been included for players to enjoy.
Let’s start things off with the paytable, and the highest value symbol in the slot is the Rottweiler dog, which will pay 5x the bet for a six of a kind win. Next, we have the cat worth 3x for all six, followed by the pug and rat, who will pay 2.5x and 2x, respectively, for a full payline of six. Moving down the pays section, we see the medium value symbols represented by four patches. These are the Dirty Dawgs and Gritty Kitty patches, both awarding 1x for a completed payline and the Pug Thugs and Rogue Rats patches, which will both pay you 0.8x for a full winline of symbols. Finishing off the paytable, we have four royal symbols, the A, K, Q, and J, all valued at 0.3x for a six of a kind win. There’s a self-titled wild symbol that can also appear on the game’s reels, which will substitute for all other standard game symbols within.
There is a good amount of stake sizes to choose from on the betting range in Nitropolis 3, with these starting at a minimum of €0.20 and finally maxing out at €50 a spin. There are the X-iter options to consider also, and I’ll cover these a little further on in the review.
Base Game & Modifiers
The standard gameplay on Nitropolis 3 takes place on a format of 6 reels, each that is 4 rows high, giving the slot a total of 4,096 ways to create a win on, initially at least. To land yourself a win, you need to match 3 symbols on adjacent reels, starting from the leftmost reel first. This is just the beginning of the action, as you’re about to discover below.
Avalanche Reels
All symbols included in a winning combination will explode, making them disappear and leaving space for new symbols to fall from the top. An additional row of symbols is also added at this time, and if you carry on creating new winning combos, the playfield can reach a maximum of eight rows high. The avalanche feature will then continue until no new winning combinations occur.
Nitro Reels
Nitro reels will also come into action as part of the avalanche mechanic. Small Nitro Reels cover two symbol positions and contain 4, 6, 8, 10 or 12 1×1 symbols each. Big Nitro Reels cover six symbol positions and feature 2, 3, 4, 5 or 6 2×2 payout symbols. Additional features can also be brought into effect with Nitro Reels, which are:
- Nitro Match – Nitro Reels on the same and adjacent reels as the Nitro Match symbol will match up the same symbols.
- Nitro upgrade – Nitro Reels on the same and adjacent reels as the Nitro upgrade symbol upgrade, and then additional symbols are added.
- Nitro Wild – All symbols in the Nitro Reels on the same and adjacent reels as the Nitro Wild will be replaced by wild symbols.
Nitropolis 3 Slot Bonus Features
The air blimp is the game’s scatter bonus symbol, and it takes at least three of these appearing to activate the free spins round. Up to 20 spins can be won, depending upon how many bonus symbols are in view, and all Nitro Reels remain sticky throughout.
Safety Levels
The safety level will advance one row for every new free spin initiated that results in a win. Every new free spin starts at the current active safety level.
Super Super Bonus & Both Ways
The combination of bonus symbols and a super bonus symbol will go on to activate the Super Bonus Game. This is played at eight rows large and with win both ways fully activated.
X-iter Feature
If you’re playing from a location where it’s possible to bonus buy on slots, then you’ll be able to access the X-iter feature on Nitropolis 3. This will present you with five upgrades to your play, each with a fixed cost to purchase, which are as follows.
- Boosted Bonus Chance: One spin that doubles the chance of triggering the bonus at the cost of 2x bet.
- Big Nitro Reel: Guaranteed big nitro reel for one spin, costing 10x bet.
- Nitro Match: Guaranteed nitro match and both ways active, for a cost of 25x bet.
- Standard Bonus: Trigger the standard bonus feature for 100x bet.
- Super Bonus: Buy the super free spins bonus for 500x bet.
Nitropolis 3 Slot Review Final Thoughts
Nitropolis 3 is essentially a much more impressive version of its two predecessors. Featuring special modifiers aplenty, the developer’s ability to incorporate fantastic graphics and stunning gameplay leaves little doubt that this is one of the best slots they have ever made. Highly recommended; go give it a try.
