I remember reading a long article about something like this in Canada or New York or someting, but here’s a lottery game in MA that’s beatable every couple months if you bet over $100K. The lottery knows about it, but doesn’t seem to be doing anything about it because, although it loses money those 10-15 days a year, it’s still making an $11.8 million profit for the year.
Because of a quirk in the rules, when the jackpot reaches roughly $2 million and no one wins, payoffs for smaller prizes swell dramatically, which statisticians say practically assures a profit to anyone who buys at least $100,000 worth of tickets.During these brief periods – â€œrolldown weeksâ€™â€™ in gambling parlance – a tiny group of savvy bettors, among them highly trained computer scientists from MIT and Northeastern University, virtually take over the game. Just three groups, including the Selbees, claimed 1,105 of the 1,605 winning Cash WinFall tickets statewide after the rolldown week in May, according to lottery records. They also appear to have purchased about half the tickets, based on reports from the stores that the top gamblers frequent most.
