Did anybody won games in one day for 200 points?

Yep. I've won games worth a grand total of 294 points in a single day. Granted, it was an event, where we had a whole lot of giveaways end at exactly the same time, it's not something that has happened under "normal" conditions.

Waay more.

I think Ive won more than 300 in a day. All from one user.
