While aboard the Royal Caribbean Harmony of the Seas, we experienced an incredible time on the ship. One thing you immediately come to understand is that the Harmony of the Seas isn’t a ship.. It’s a mega yacht city that has EVERYTHING you can possibly think of. We typically don’t like playing slot machine games like Miss Kitty, however, we found ourselves with some spare time before dinner, and we decided to play it. The game is by Aristocrat, and the way you get a slot machine jackpot on this game is to hit the wheel on the Grand Jackpot! #RoyalCaribbean #SlotMachine #LasVegas
