In Nitropolis 4, ELK Studios envisions a world without humans, where animals rule instead. This newest release in the Nitropolis series is just as adrenalized and action-packed as the previous ones, if not more so. A quick glance at the paytable reveals a variety of features like Nitro Boosters, Nitro Multipliers, Nitro Reels, Avalanches, Big Symbols, and two bonus games. There’s plenty here for players to enjoy.

The studio had the opportunity to create some more exciting dystopic visuals in Nitropolis 4, and the audio does not disappoint. The bleeps, voiceovers, and heavy-duty industrial tunes are a perfect mix of chaos. The gameplay is sure to be just as exciting.

Max win on NITROPOLIS 4? Feature checking 🙂

The Avalanche mechanic is one of the most exciting features of ELK Studios slots. When a win occurs, the symbols are removed from the board and replaced by new symbols dropping down. An additional reel is also added at the top, up to a maximum of 8 rows high. Nitro Reels and Nitro Multipliers are part of a win respin during this process. Avalanches keep lanching until no new winning combos hit.

  • Big Symbols: Bigger is always better, right? That’s certainly the case when it comes to symbols in Super Slots. On any given spin or symbol drop, you could see a 2×2 symbol or an even bigger 3×3 symbol. Plus, any pay symbol or the wild can land as a Big Symbol. So keep your eyes peeled for those supersized wins!
  • Nitro reels: Nitro Reels occupy two slots on the board and can land on any reel. Each Nitro Reel contains 4, 6, 8, 10, or 12 regular-sized payout symbols. Big Nitro Reels occupy six slots and contain 2, 3, 4, 5, or 6 2×2 payout symbols.
  • Nitro Multiplier: Nitro multipliers are symbols that multiply all wins in view. They can have values of x4, x6, x8, x10, or x12, and when more than one is in view, they are multiplicative.
  • Nitro Booster: The two displays located above the grid can award Nitro Booster modifiers. There are a total of 8 possible effects, which are as follows:
    • Redrop: When there are no more wins, the Bonus symbols and Nitro Reels are held while all other symbols are replaced with new ones. This keeps things exciting and gives players the chance to keep winning.
    • Both Ways: Wins pay from both sides on the grid.
    • Nitro Wild: If you see a Nitro Reel, it will be filled with wilds. If you don’t see a Nitro Reel, this feature will be held until one appears or the game round ends.
    • Nitro Appear: A Nitro Reel of random size is placed on the board.
    • Garbage Collect: As random symbols are removed from the grid, an avalanche of new symbols appears, causing a domino effect that can quickly overwhelm the player.
    • MAX Rows: You get a full 8-ro hight board.
    • Nitro Upgrade: The value of a Nitro Reel is increased when it is in view. If there is no Nitro Reel, this feature is held until one appears or the game round ends.
    • Nitro Match: If you have a Nitro Reel, it will be matched with another symbol to create a win. If there’s no winning match possible, the Nitro Reel will be matched with an adjacent reel. If that’s not possible, it will be matched with the highest adjacent symbol. If there’s no Nitro Reel on the screen, this feature is inactive until one appears or the game round ends.
NITROPOLIS 4 – Slot Review

Nitropolis 4 – Bonus, SuperBonus and Free spins

3, 4, 5, or 6 bonus symbols award 8, 12, 16, or 20 free spins. During free spins, Nitro Reels are sticky until the feature ends. Also, each win increases the safety level by one row. The next free spin fills the grid to the current safety level, with a maximum of 8 rows. If one of the triggering symbols is a Super Bonus symbol, then the Super Bonus Game is awarded. In this round, Max Rows and Both Ways is always active. The X-iter function allows players to play to boost the possibility of getting the bonus or even buy FREE spins or SuperBonus.

Nitropolis 4 – Review conclusion

The Nitropolis series has always been a crowd-pleaser, and Nitropolis 4 is no exception. The game world is highly immersive, and ELK Studios does a great job of making it look even better with each installment. The animals running the world might seem odd, but it’s actually quite humorous and provides plenty of opportunity for the studio to create an absorbing sensory experience.
