Great Blue is a 25 line ocean-themed slot from Playtech with stacked wilds and a gamble feature. The wild symbol is the Killer Whale and as well as being stacked on all reels it doubles all wins.
The oyster symbol is the scatter. Three or more oyster scatter symbols anywhere triggers the bonus round. You start with 8 free spins with a 2x multiplier and get extra free spins and/or a bigger multiplier via a click and pick. The free spins can be retriggered indefinitely and if they are, you get 15 extra free spins at the same multiplier as before (instead of the click and pick)
