The husband-and-wife each bought Wisconsin lotto tickets that have won $350,000 apiece.
Verlyn Adamson says he's a fan of math puzzles and claims to have developed a secret formula to predict winning lottery numbers.
He bought the first ticket.
His wife bought another using the same numbers, which paid off last weekend.
Adamson says he's won jackpots before using his supposed formula, but nothing this big.
