Full Marks is a limited-time event in which players are presented with a 16 tile board. Each tile displays a certain objective that the player must fulfill. Each Full Marks event will have a leaderboard where players will compete with other Hogwarts Mystery users.
Upon completing the objective listed on a tile, points are given toward the event. Completing the different tile patterns will reward points that will contribute to your score on the leaderboard.
When the event ends you will earn rewards corresponding to your leaderboard rank. You will receive the prize for your current rank and all rewards below that rank.
