Live an enigmatic Harry Potter adventure in Cannes! An evil spell has condemned the famous 9 ¾ track! The access is thus not possible any more by the station of King's Cross. The boarding of the Hogwarts Express would be from now on in the World Capital of the 7th Art... As Muggles, it's up to you to thwart this bad spell by finding the access to the platform as soon as possible! Head for the Croisette on the Square Reynaldo Hahn to begin this great adventure. But beware: the train will pass by in 2 hours! Your smartphone will show you the location of each house that are in the city center. In each of them, 4 code words to be guessed within the time limit. They will allow you to find the location of the track. And that's not all: you will also have to collect key clues to find THE code word that will validate your passage in each house. You'll also have to solve puzzles, meet wizards and find bonus cauldrons. The Hogwarts Express will leave in 120 minutes. Tick tock tock... Time is running out!
