Mega Symbols, Multipliers, Expanding Reels, Free Spins, and a Super additional Game are among the additional features. Nitropolis 4 has a high variance and a pitiful return to player percentage.

The Nitropolis series has a humorous dystopian theme, and the game takes place in a fictional universe ruled by animals. The animal crew in Nitropolis 4 is at work, specifically extracting resources at sea. Presumably, they are unearthing Nitro, which has a crucial role in the game's additional features. The industrial soundtrack and various sound effects are of superior quality and contribute to the game's excitement.
Regarding the paytable, there are low-paying J-A card symbols, four gang insignia as medium-paying symbols, and four animal symbols as high-paying symbols. A 6-of-a-kind winning combination awards 0.30x for card royals, 0.80x to 1x the wager for gang emblems, and 1.25x to 3x the wager for premiums. The mine is the Wild symbol, which appears on all reels, substitutes for regular symbols, and offers the same payout as the symbol with the maximum payout.
In addition, Bonus and Super Bonus symbols trigger bonus games.
Nitro Reels can rest on any reel and take up two positions on the playing grid. These positions comprise four to twelve symbols of standard size. Big Nitro Reels contain 2, 3, 4, 5, or 6 large 2x2 symbols across six positions.
Nitro Multipliers can contain multiplier values ranging from 4x to 12x, which will be applied to your rewards.
There are two displays located above the grid. These screens exhibit gameplay-enhancing modifications. Each of the eight potential modifiers is assigned at random.
