Old Harry Potter Game (Duels)

Hello guys! I'm looking for this Harry Potter game where you can duel with other online members by doing the patterns for each spell using your mouse or trackpad and not the keyboard. You get to battle with other people who are online as well. I played it back in, maybe '09 or '10 so, I really can't remember and I was still a kid back then. I'm pretty sure it's not Pottermore. It was really fun and I would just like to check out if the website's still alive :( Thank you in advance!
