DES MOINES, Iowa (AP) -- Powerball is a game of numbers, and lottery officials say the majority of possible combinations have already been purchased ahead of Saturday night's near-historic $600 million drawing.
The odds of winning the game's largest jackpot remain astronomically high: 1 in 175.2 million.
But since about 80 percent of the possible combinations have been purchased, lottery officials say it's likely the winning ticket could be selected.
People lined up at gas stations and convenience stores Saturday for their chance at striking it rich.
South Carolina resident Benjamin Richardson says the few bucks he spends for every drawing are worth it. He also reasons that "it's all luck anyway."
The latest jackpot is the world's second largest overall, just behind a $656 million Mega Millions jackpot in March 2012.
