This games does not have the standard type of paylines, here you have to match symbols in a cluster instead. This is called Cluster Pays. In most jurisdictions you can also select the Autoplay option when playing Great Blue. You can choose from 10, 25, 50, 100 or even more spins. You can opt to stop Autoplay on a win, if a single win exceeds a certain amount, or if your balance increases or decreases by a chosen amount. This is a great way to stay in control and to play more responsibly.

Playtech have chosen not to add a free spins bonus round in this game and that is quite uncommon nowadays.
