Players enter fantastical free-roaming 3D environments from Harry's world. Players become Harry Potter and delve not only into Harry's world, but also into his personality, via an internal "voice." Conversing with unique characters like Moaning Myrtle, shopping in Diagon Alley, and exploring the convoluted corridors of Hogwarts, players make crucial and independent decisions within Harry's world. Additionally, Harry can, of course, cast spells against foes - but these spells must be perfectly executed, or they could be miscast with humorous or critical consequences! Mini-games within levels can be revisited, so players can help Mrs. Weasley with "de-gnoming" her garden, challenge other students in Professor Lockhart?s Dueling Club, or complete other mini-games again and again.
