This is an adventure game in which players assume the role of a small Lego-version of Harry Potter as he learns magic spells and defeats enemy creatures at the Hogwarts magic school. Players use a wand to fire fantastical blasts at enemy monsters, spiders, snakes, wizards, pedestrians, etc. Characters sometimes cry out in pain and often break apart into smaller Lego pieces when defeated. In one cutscene, a character's body explodes, and the central character cradles the head piece; another sequence depicts a dragon impaled through the mouth by a sword. Players can also control one of the game's antagonists who casts energy spells at fleeing wizards. In one sequence, brown Lego droppings fall out of a creature's posterior; a character scoops up the droppings with a shovel and remarks with a comical "Pee-ewhh" gesture.
