Pottermore - the project of Joan Rowling. It is a mixture of the news site with the encyclopedia of the world of Harry Potter. Until September 22, 2015, the project was a mixture of the game with a source of additional information about the world of Harry Potter. The project is available on a free basis, but periodically offers to buy e-books, which is not necessary.
