Whoever is holding the single winning ticket for the $521 Mega Millions jackpot is about to discover the tricky part of winning big: remaining anonymous.

The ticket for Friday night's drawing was purchased in New Jersey, a state that does not allow lottery winners to claim their prize anonomously.
