Harry Potter Wizards Unite: Pokémon Go for the Potterverse is released on Friday

Everything you need to know about the next big augmented-reality game before its 21 June release date

Harry Potter: Wizards Unite will bring a little magic into the world tomorrow, as fans will be able to step into the world of the Boy Who Lived thanks to the augmented-reality smartphone game.

Players use their phones to tackle something called the Calamity, which has tossed all sorts of dangerous magic - Confoundables - into the everyday world of muggles. Exploring the real world around them, they'll run into familiar forms for fans of the Potterverse, such as pixies guarding screaming Howler letters or Hogwarts students trapped by vines. Casting spells on them by tracing lines on the phone's screen will send them back where they belong, adding to the player's collection of magical objects fished from the streets.
