How the ticket numbers were given out
Ticket numbers are not handed out in the order tickets are bought. They are shuffled by a key that was fixed and published as the fingerprint below before this competition went on sale, so the order could not be arranged around anybody. The key itself stays private until the competition is over, because together with the instant-win seed it would say which purchase lands on a winning number.
