Sailing off to a hidden island in the tropics and looking for treasure is probably everyone's fantasy. In that it isn't possible for many to do, at least making a game of it can be fun! Even if there isn't any buried treasure, sailing off to a tropical paradise would be enough of an incentive.
In the Hidden Island game, you must remove an ancient spell that was cast on the island, and learn the mystery of the island. Have fun if you decide to sail on over to the hidden tropical island, but you just may need to escape from paradise!
