What are the chances of winning at Nitropolis 2?

As you may have read before in this review, Nitropolis’s Profit Benefit rate (RTP)is 2 95%. This percentage is, on average, on the low side compared to other slots offered (online). The RTP is always expressed in the form of a portion. This is done because this percentage represents the average that can theoretically be recovered as a profit from an (online) gambling game. The higher this percentage is, the more attractive this game could be for a player.

In addition to RTP, you deal with high variance in Nitropolis 2. Variance, also known as volatility, of a gambling game, is the degree of spread of a set of values. In other words, the extent to which the values can differ from each other. For example, the higher the variance is in an (online) slot game, the more mutual values will vary and the more it will be off the average.

How do Nitropolis 2 free spins work?

Sergeant Nitro has a car called the Nitro Truck. When it appears 3 times in the same spin, you can squeeze your hands as you enter the free bonus spins round. When you have played 3, you will receive 10 free spins. The more Nitro-Trucks you see passing per round, the more spins you will receive. When you have managed to run 4 of them, you can spin 15 times for free, 5 Nitro-Trucks allow you to spin 20 times, and at 6 times the Truck, you can go free of charge on the reels 25 times.

The advantage of this free spins round over the base game is that the Nitro Reels stick throughout the entire free spins bonus round. Of course, this can result in enormous great prices. When you make sure to spin 3 or more bonus symbols from the Nitro-Truck during the free spins, these are added to the free spins that are already there. In theory, this can continue indefinitely. The free spins bonus round can only be stopped prematurely when you have reached the maximum win of 10,000 times your stake.
