Updated at 1:57 p.m. (AP) OMAHA, Neb. - Lottery ticket lines swelled Friday as the record Mega Millions jackpot grew to $640 million, thanks to players who cast aside concerns about long odds and opened their wallets for a chance at becoming an overnight millionaire. A cafDe worker in Arizona reported selling $2,600 worth of tickets to one buyer, while a retired soldier in Wisconsin doubled his regular weekly ticket spending to $55. But each would have to put down millions more to guarantee a win. "I feel like a fool throwing that kind of money away," said Jesse Carter, whose two tickets purchased Friday at a Milwaukee grocery store brought him to the $55 mark. The $640 million jackpot, if taken as a $462 million lump sum and after federal tax withholding, works out to about $347 million. With the jackpot odds at 1 in 176 million, it would cost $176 million to buy up every combination. Under that scenario, the strategy would win $171 million - less if your state also withholds taxes. Laura Horsley, who does communications and marketing for a trade association, bought $20 worth of Quick Pick tickets at a downtown Washington liquor store Friday. But Horsley, who said she won't buy a lottery ticket unless the jackpot tops $100 million, said she remained realistic. "I don't actually think I'm going to win, and I don't believe in superstitions or numbers or anything like that," she said. I just figured it's right around the corner. I'd be crazy not at least to give it a shot. Thousands of players - who converged on convenience stores in 42 states and Washington, D.C., where Mega Millions tickets are sold - agreed. Many in Indiana were further encouraged by the promise of freebies: Hoosier Lottery officials gave away one free Mega Millions ticket to each of the first 540 players at several outlets around the state Friday - a plan announced before the jackpot grew by $100 million. The lines were out the door at Rosie's Den cafe in the rural northwestern Arizona community of White Hills, 72 miles southeast of Las Vegas and one of the closest points to Nevada - which doesn't offer Mega Millions - for buyers to get in the game. Rosie's worker Christine Millim said it's been nonstop for four days. "In one step I sold $2,600 worth so, that was one person," she said. But even buying 10 tickets filled out 10 different ways only increasing odds of winning the jackpot to 10 in 176 million.
