How Did Fred & George Figure Out The Marauder’s Map In Harry Potter? Prisoner Of Azkaban Has The Answer

Fred and George Weasley never revealed how they figured out the complex steps to using the Marauder’s Map, but the artifact itself might have provided the answer in Harry Potter and the Prisoner of Azkaban. Made by James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew, the map miraculously found its way into Harry’s hands during his third year at Hogwarts. Before him, Fred and George had been using it for three years, ever since they found it in Argus Filch’s office. The complicated password that causes the Marauder’s Map to reveal its secrets wouldn’t have been easy to work out without help, but the twins never told Harry how they did it.
