The wizards and witches from the four houses (Gryffindor, Hufflepuff, Ravenclaw, and Slytherin) sneak out of the house unnoticed to gather in the library. Beware: If the caretaker catches them or they encounter someone from another house, they will be sent back to the dormitories and must set out again. Teams are formed and they navigate through the corridors of Hogwarts using maps. The first team to gather all its wizards and witches wins the coveted reward of the night: a whole bag of Bertie Bott's Every Flavor Beans. DOG - The brilliant game hit from Switzerland - now as a special edition for all young and old Harry Potter fans.
