The Jackpot symbol is the Aztec Treasure logo. The current jackpot amount can be seen above the reel, and the reel can only be won when the maximum bet is won. After each rotation, you can choose to keep one or two reels and then rotate them again. This can come in handy if you think that holding the reel can bring you the next spin victory.
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.
