They claimed those jackpots Thursday. All four were purchased at different locations, but with the same numbers and for the same drawing. Their winnings now amount to $1.4 million, or about $955,000 after taxes.
The Adamsons left a voice message on their phone saying they wouldn't have any public comment and referring any questions to their lawyer Scott Thompson.
Verlyn Adamson said earlier in the week that he's a big fan of math puzzles. He claims he developed a formula for lottery picks, but his winnings have been small until now.
Thompson said the Adamsons are "exploring patent protection" for the equation.
But Steven Post, a mathematics professor at Edgewood College in Madison, wasn't buying it. He said there is no way to devise a strategy for finding the winning numbers in a game that uses randomly generated numbers to determine the winning combination.
The only strategy would be to "buy all the tickets," he said.
