Thwart the Harry Potter curse in Nantes! An evil spell has moved the access to platform 9 ¾ in the Venice of the West! The train will pass in 2 hours and it's up to you Muggles to do everything to find it. Thanks to your smartphone, try to gather 4 code words in the given time to find the location of the platform. They will then lead you to the deduction of the code word that will reopen the access to the platform. On the program: solving riddles, meeting wizards who will give you a good or not so good surprise or even bonus pots. The Hogwarts Express will leave in 120 minutes. Tick tock tock...
