Great Blue has standard features other than free spin bonuses. The wild does not provide anything you can't see in other video slots. Betting options and other game settings put the player in control, which has always been a big benefit for Playtech.
The game is wildly displayed as a whale in any position. These symbols provide more payment because they can represent other symbols and ultimately get more bonuses, which means that the wild can also expand the reward by making the combination bigger and offering higher bonuses. All game symbols can be wild, but scattered because they don't require any paylines or special orders to reward.
