That's why i don't even bother with stuff where the single winner is going to be "that one guy" with really fast internet connection who is try-hard enough to get the code in less than 2 minutes after maintenance, i wouldn't be surprised if someone redeemed it early before maintenance by entering every combination possible using some kind of bot to automatically enter them for them one by one, (Probably doable because we had half the code revealed), there's no captchas for the serial codes as far as i know so they can totally do that.
