Nitropolis 4 RTP and Volatility

This is a high-volatility game with an RTP of 94%.
Nitropolis 4 comes with a high variance level and a miserably low RTP rate. Return-to-player percentage for this slot is set at 94% which is much lower compared to the other games in this genre that usually come with an average of 96%. The game is highly volatile, meaning that wins will not come around frequently, so players need to have patience and a decent bankroll to get the most out of this slot.


Nitropolis 4

Nitropolis series has a fun dystopian theme and the game takes place in an imaginary universe where animals rule the planet. In Nitropolis 4 the animal crew is at work, specifically doing resource extraction at sea. Presumably, they’re dredging up Nitro which has a key importance when it comes to the game’s bonus features. The industrial soundtrack and all kinds of sound effects are of top quality and add extra excitement to the gameplay.

Speaking of the paytable, there are low-paying J-A card symbols, four gang logos as the medium symbols, and four animal characters representing the high-paying symbols tier. Landing a 6-of-a-kind winning combination awards 0.3x for the card royals, 0.8x to 1x the bet for the gang logos, or 1.25x to 3x the bet for premiums. The mine is the Wild symbol that appears on all reels and substitutes for any regular symbol as well as offers the same payout as the highest-paying paytable symbol.

Also, there are Bonus and Super Bonus symbols that activate bonus games.

Overall Rating


Nitropolis 4 is an awesome slot that offers engaging gameplay and multiple generous bonuses. ELK Studios did a great job designing this title, and all the fans of the previous installments of the Nitropolis series won’t be upset with part 4. This game can be extremely profitable as the maximum possible win is a 50,000x bet.

However, it’s a high-volatility slot, and a tiny bankroll may disappear before any significant win will be obtained.
