The game is viewed from above. Players guide Harry through Hogwarts and tournament-related locations, fight enemies with spells, collect items, and solve environmental obstacles. Ron and Hermione appear as supporting characters during missions.

Progression follows a sequence of story stages rather than a freely explorable campaign. Completing objectives and encounters advances the film-based narrative, while exploration can reveal collectibles and useful items. The Game Boy Advance edition is designed primarily for single-player play.

Explore each area before leaving it, because collectibles and useful items may be placed away from the main route.

Use the spell or attack best suited to the enemy and avoid standing still during encounters. When an objective is unclear, revisit nearby rooms and check for interactive objects.
