In Crystal 2-6 players try to find some hidden treasures and bring them back to the 2 starting points. A special die not only lets players move 0-3 fields, it also determines if a treasure is found and if other special features, like the arising of a crystal wall, appear. A funny aspect are the 4 transparent "glass-witches" which are mainly used to annoy other players. Much luck after all, but nice components anyway.
