Nitropolis 4 Slot Review

The fourth installment to the Nitropolis slot series by ELK Studios is here. Having in mind the prequels, expectations are that Nitropolis 4 will be the best freakshow so far. You’ll be seeing the same animals who took control over the world again, taking you on another yet nitro-fueled action.

Set on a 6-reel grid, with 4,096 ways to win, the slot offers reel expansions that can allow for up to 8 symbols on each reel. Packed with features like Both Ways mechanics, Avalanches, Big Symbols, Nitro Reels, Nitro Multipliers, Nitro Boosters, Free Spins and the X-iter bonus buy options, fun is guaranteed.

Nitropolis 4 Slot Setup and Paytable

Leaving the city, the Nitropolis 4 slot takes you seaside, where it looks like the animals are involved in extracting their fuel at sea. You can see the machinery in the background and the reels seem like they're the crucial part of it.

On the right of the reels, you see the Autoplay button in the top corner and the Play button in the bottom corner. The Bet and Balance displays are in the footer. On the left, in the bottom corner, you have the Coins button, where you can adjust your bet level. Regular bets from $0.20 to $50 can be placed, but as you can see, there’s the X-iter button above the Coins button, where you can place additional bets, to be explained below.

The three-bar button is in the top left corner, and that’s where you’ll find the paytable. You'll see the playing card Royals as the low-pays, giving you up to 0.3x the stake, followed by the four mid-paying gang logos, giving you 0.8x to 1x the stake for a 6-of-a-kind combo. The four animal characters deliver 1.25x to 3x the stake for the top combo. There's also a Wild, presented with a mine tile, which not only substitutes for regular symbols but also pays out for its own wins, giving you 3x the stake, just like the highest-paying symbol.

Nitropolis 4 Slot Base Game

About the Avalanches, winning symbols are removed from the grid allowing for new ones to drop down. There’s an extra reel on top of the grid which can hold up to 8 rows. During the Avalanches, whenever Nitro Multipliers or Reels are part of a win, they award a Respin.

Big Symbols sized 2x2 or 3x3 can land at any time. Any regular symbol or Wild can appear as a Big Symbol. Nitro Reels can land on any reel and cover 2 positions, containing 4 to 12 regular-sized symbols. But, there’s also a chance for Big Nitro Reels to land, which will contain up to 6 symbols sized 2x2 and cover six positions on the grid.

Nitro Multipliers count as one symbol and cover two positions on the grid, multiplying all wins on that spin. The values they hold can be from 4x to 12x, which multiply if more than one is in view.

Nitropolis 4 Slot Free Spins and Bonuses

8 Nitro Booster modifiers can be awarded from the two displays above the grid. Both Ways, which is pretty self-explanatory, Redrop, which holds Nitro Reels and Bonus symbols on the reels while others are substituted by new ones, and Max Rows, where the grid expands to 8-row high. Garbage Collect removes random symbols from the grid, triggering an Avalanche. Nitro Appear places a Nitro Reel of random size on the grid. Nitro Upgrade increases a Nitro Reel. Nitro Wild fills a Nitro Reel with Wilds. And finally, Nitro Match matches an existing Nitro Reel to another symbol on the grid to form a win.

You trigger 8, 12, 16, or 20 Free Spins when you land 3 to 6 Bonus symbols, respectively. During the Nitropolis 4 Bonus Round, Nitro Reels become Sticky and each win you land will increase the safety level by 1 row. Should you’ve triggered the bonus with at least one Super Bonus symbol, you’ll trigger the Super Bonus where Both Ways and Max Rows are always active.

Finally, you can play the game in 5 modes. Pay 500x the stake and you'll get direct access to the Super Bonus. Pay 100x the bet and you'll get to the regular Free Spins. For 25x the bet, you'll get a spin with Both Ways and Max Rows active. For 10x the stake, you'll get a spin with two Nitro Booster features. And for 2x the stake, you'll get a spin which will give you more than double the chance of triggering the Free Spins.
