This is an adventure game in which players assume the role of small Lego-versions of Harry Potter and his friends as they practice magic spells and defeat enemy creatures at the Hogwarts magic school. Players use a wand to fire fantastical blasts at ghostly figures, giant snakes and spiders, and other wizards. Characters screech or cry out in pain when hit, and often break apart into smaller Lego pieces when defeated. In some sequences, players engage in one-on-one wand duels with other characters; one duel ends with a character dramatically dissolving into the air. A few scenes include instances of slapstick humor: a skeleton creature burping; a character floating from a geyser in a toilet; a wizard covering up after his pants are zapped away.
