Part of me wonders if each time the announce a batch of winners, it starts again. Impossible to tell though.
edit: oh. there was also a winner who was possibly removed. the ninscala.com site counted down to 20, then on a refresh was 21 again. i didn't see who it was though, so the removed person may well have won and been put back.
