The bonus round is a great blue when you enter yourself and the player can get a good return. We have to say that in the bonus round of the Great Blue trough, it is not uncommon for the return to exceed 100 times your bet. The bonus back merger does not happen very often, but when it does happen, it really deserves to wait. To get a bonus round from a US player in the Great Blue slot, you must hit three or more scatter symbols in one spin reel. The Scatter symbol is represented by the open Clam Shell.
After the bonus round is granted, you can see five closed clams. All you have to do is pick two cockroaches to open. After opening the clamshell, you will get extra rotation or extra bet multiples.
