I had a very long and disappointing session when it comes to this game. I played it on auto play and it is very slow that way because it counts the winning separately on every line. I played around 200 spins and I was 80 euros in minus and just when I was about to quit I triggered the bonus round. The heart shaped symbol with Maritime Maidens is the scatter. If you land 3 you trigger the bonus round and they turn from blue into red. Once you open the bonus round you have 2 options from which you can choose. There is a heart with “pick a shell” written in it and there is another heart with free spins. I chose the pick a shell feature and there are 25 shells from which you have to choose. Every time you open 2 shells with the same amount you get one pearl. After you collect 4 pearls the bonus is over. I got 50 x bet in this bonus. I have to say that I was not very impressed with this amount if we consider the fact that I have lost a lot of money in the base game.
