Review Nitropolis 4
It’s time again for a new trip to the dystopian land where animals with human behaviour fill in the central roles. The Nitropolis 4, as the name suggests, is the fourth instalment of the popular series with an original theme. Once again, ELK Studios has added a title with 6 reels and 4,096 ways to win to its catalogue. The visuals of this release have not changed much in comparison to its predecessors. This means we have metallic reels filled with colourful icons and a background image showing something that reminds us of an oil refinery. All of this is presented with unusual and therefore memorable sound effects.
How to Play
Nitropolis 4 is an online pokie that is offered by many online NZ casinos and isn’t too difficult to understand, although some basics will need to be learned to get the most out of it. Bear in mind this is a game with a Megaways mechanism and works both ways. Also, there are many features to be enjoyed which requires some learning. Here is how to play Nitropolis 4:
- Press the blinking curved arrow in the lower-right corner to get started as this is the game’s play button. Of course, you can automate the process thanks to the auto arrow on the right side. We suggest you make moderate use of this option.
- This simple feature enables you to launch 10 to 100 automated rounds. As for the bet size, you start with $ 0.2 and go all the way up to $ 50.
- Pressing on the three lines will open a new window and the paytable is the first thing they will see. You can use the settings/gear icon to regulate the general settings and the info sign to read the game rules.
- Remember to set your betting limits and adapt these to your bankroll. Set them before you make your first spins and stick to these limits.
The graphics are bold and.. beautiful, with the music of the game sounding between industrial and futuristic. The symbol effects when things start to happen on the reels are great. On the reels, the A-J Royals make up the low values. These are joined by high values recognised by the emblems and numerous bosses – rat, pug, kitty and dawg. Out of these, the Dawg Boss symbol is the most rewarding, paying 1.5, 2, 2.5 or 3x your stake for combos of 3, 4, 5 or 6. Between 3 and 6 matching symbols are needed on adjacent reels from leftmost to the right to win, and the premium character symbols pay between 1.25 to 3x your bet. The spiky mine is the game’s wild symbol and can appear anywhere to step in for pay symbols. Wilds pay the same as the top-tier Doberman roughneck symbol. Here’s more you need to know about the different symbols in the game.
|Symbol||Payout for 3||Payout for 4||Payout for 5||Payout for 6|
|Rogue Rats Emblem||0.15||0.25||0.4||0.8|
|Pug Thugs Emblem||0.15||0.25||0.4||0.8|
|Gritty Kitty Emblem||0.2||0.3||0.5||1|
|Dirty Dawgs Emblem||0.2||0.3||0.5||1|
|Wild||Substitutes for all Symbols Above|
|Scatter||3+ Activates Bonus Game feature|
Nitropolis 4 wouldn’t be a Nitropolis pokie without a whole bunch of features. In this online pokie machine we have wild symbols, an avalanche mechanism, big symbols, nitro reels, a nitro multiplier, a nitro booster and a free spins round on offer for you. Let’s go.
In virtually any other game you don’t want to encounter mines, but in Nitropolis 4 you do. The mines are the wild symbols and you always want them on the playing field.
The avalanche mechanism comes into action when you form a winning combination. In that case, the avalanche starts by removing the winning symbols, after which new symbols fall on the playing field. That’s not all, because there will also be an extra row added to the top of the playing field. If you have reached a total of 8 rows, the playing field will not grow any further. When no new combinations are made, the avalanches stop and you move on to the next spin. The playing field also shrinks back to the original height of 4 rows.
In Nitropolis 4, there are not only normal symbols of 1×1 that land on your grid, but you will also encounter super symbols and mega symbols. These symbols come with a size of 2×2 and 3×3 respectively and can fall on the playing field on any spin and during all avalanches. All regular symbols and the wild symbols can land as a super symbol or mega symbol.
Nitro reels are not extra reels for the playing field, but are symbols that can land on the playing field. They are 2 squares in size, can land on any reel and contain 4, 6, 8, 10 or 12 regular symbols. Large nitro rolls also exist. These are 2×3 squares in size and have 2, 3, 4, 5 or 6 super symbols of 2×2 with them.
The nitro multipliers are also symbols that can land anywhere on the playing field. They are 2 squares in size and come with a multiplier of x4, x6, x8, x10 or x12. This multiplier is applied to all wins that are on the playing field, at the same time as the nitro multiplier.
At the top of the playing field you can see 2 blue screens. These screens can randomly trigger the nitro booster modifiers. The modification options are as follows:
- Redrop: if there are no new wins, you get a respin where all scatters and nitro reels remain on the playing field.
- Both Ways: here you not only get a win from left to right, but also from right to left.
- Garbage Collect: this modifier removes a number of random symbols from the playing field, causing an avalanche.
- Max Rows: the playing field is increased to 8 rows high.
- Nitro Appear: this gives you a random sized nitro roll.
- Nitro Wild: if you have a nitro reel on the playing field, it will be filled with wild symbols.
- Nitro Upgrade: the value of a nitro roll on the playing field is increased.
- Nitro Match: the symbols in a nitro reel on the playing field are changed into a symbol on the playing field, causing a win.
Nitropolis 4 Free Spins
To reach the free spins round, you must first collect 3 or more scatters. How many free spins you win depends on the number of scatters:
- 3 scatters = 8 free spins.
- 4 scatters = 12 free spins.
- 5 scatters = 16 free spins.
- 6 scatters = 20 free spins.
You also get these amounts of free spins as extra spins when you land enough scatters during the free spins round itself. The nitro reels are always sticky during the free spins round of Nitropolis 4, making them stick around until the end of the round. Each win increases the playing field, until you have a maximum height of 8 rows. The rows are not reset between spins.
If you manage to spin a super scatter, you will get the super free spins round. Everything that has been said above applies here, but in the super free spins round, the modifiers max rows and both ways are always active.
X-iter Feature Buy
There is an X-iter Feature Buy menu option available for players based in NZ. Here is an overview of what you can get:
- Bonus Hunt: pay 2x your bet to more than double your bonus round chances.
- Nitro Booster: pay 10x your bet to get 2 guaranteed Nitro Booster modifiers.
- Super Spin: pay 25x your bet to get a spin with both Max Rows and Both Ways active.
- Bonus: pay 100x your bet to get a guaranteed bonus round trigger.
- Super Bonus: pay 500x your bet to get the Super Bonus Round.
The payout metrics are quite different than in the last Nitropolis pokie. The Nitropolis 4 RTP is set at 94%, which is on the low side. In comparison with the Nitropolis 3 pokie, it’s a full 1% lower. Variance is high, so expect less frequent and bigger wins. Do note that the volatility level is higher than the previous release, which was around the medium to high bracket. The top win is capped at 50,000x your total stake. This is an outstanding figure if you ask us and better than most other NZ pokies. Your best chance of landing the top prize comes in the free spins feature as it offers unlimited free spins.
The improvements in Nitropolis 2 versus the original Nitropolis pokie were very clear. Then in March 2922 came part 3 with a much-improved potential top win, which is why we expected Nitropolis 4 pokie to impress as well. We were very excited to play this new casino game and review it, but although it is a great online pokie, a few things were actually somewhat disappointing. We were hopeful that the RTP rate would’ve improved. Unfortunately it didn’t. With a low 94% RTP rate, this is not the way to reward your loyal Nitropolis fans. Negatives aside though, it still is a great pokie to play. The graphics are outstanding and the soundtrack is as strong as ever. Overall, ELK Studios has managed to produce a smart game with heaps of bonus features. We would definitely recommend it and give it 8 out of 10 stars. If just part 5 comes with a decent RTP (fingers crossed).
