There is only one bonus feature in this slot but that does not mean that the game is boring. I triggered the bonus after just 3 spins and I got 17.40 euros in bonus. I got 12.72 in the next bonus round which is good considering the fact that you get only 5 free spins. This is the main thing that makes this game so interesting. Let`s talk Derby free spins are so easy to trigger by landing 3 or more scatter symbols. I know that 5 free spins are not a lot for someone but they have a lot to offer. The girls become wild and this means that you will hit a winning combination with every spin.
There are also regular wins during the base game too. I always choose this game when I lose a lot of money on other games. When I have around 10 euros on my balance and I know that I am going to lose them too very fast I start to play Roller Derby. Frequent payouts during a base game and free spins always increase my balance. I would highly suggest this game to everyone because I have not seen a game that triggers the free spins so regularly like this one does.
