Where can you play Harry Potter virtual interactive Hogwarts free online without having to register

There is no such thing that I know of; but are some good ones where you do register:
- Pottermore: You can buy books, a wand, and more. You can also do potions and spells! You get sorted too! Its really fun and J.K. Rowling created it herself!
- Chamber of Chat: This is very fun; you can do spells, ext its awesome you don't really have a house, but its still cool.
If I where you I wouldn't do:
- myhogwarts.com: It has a long wait and you have to do homework. I was a third year and our internet went down for a few months and my account was deleted, not the best site!!
