Great Blue is a video slot by Playtech, themed around underwater world and its inhabitants. Cute tropical fishes, turtles and seahorses are supposed to create a relaxing atmosphere, with bubbling sounds perfectly supplementing it, and… *yawn* we have to take a nap now.
The sleepy underwater kingdom is shaken up when you hit special symbols. The wild (a killer whale) substitutes for other symbols and doubles a win, while the scatter (a pearl shell) triggers the bonus.
The bonus round of free spins is triggered when you get three or more pearl shells scattered on the reels. By default, you get 8 free spins with x2 multiplier. Before they begin though, you choose two shells out of five, and reveal additional spins and/or multipliers (up to 33 and x15 respectively). Three more scatters during the round give 15 more free spins (at the existing multiplier).
“With up to 33 free spins and up to x15 multiplier, the bonus round in Great Blue is definitely worth waiting for”
There’s also a simple gamble feature in Great Blue, where you guess a color of the card and double your win if you guess correctly.
Great Blue slot has a nice relaxing theme (maybe a bit too relaxing) and a round of free spins with potentially huge multiplier. Seriously, it can get as high as x15, and the round is infinitely retriggerable.
