I need either doll or shuriken in my last sign-in to get 30 points. Logged in every day, only 1 day left, 28 points. This event should have given rewards depending on number of log-ins, instead of points. This way seems too much luck-based, since some people might log in every day and still might not get every reward. Hope me best luck for tomorrow's sign-in.

Update about my case: shuriken. I got my 3rd. Was worried for most of the month though...
