Thanks to her 1993 Lotto Texas win, Joan Ginther had $270,000 coming in every July through 2012. Many gamblers reason that winnings are found money, the lottery's money, house money, so why not risk some, or most? Even if you lose it all, you're no worse off than when you started. So, Ginther didn't need a foolproof strategy or some pay-as-you-go ticket-screening process to justify a search for huge prizes. If games were relatively reasonable bets, she could probably afford to risk sizeable sums every year.
