The Idaho Lottery is expecting lines of ticket-buyers into the weekend as the jackpot for Saturday night’s Powerball drawing hits a record $600 million. It’s the second-biggest jackpot on record, eclipsed only by the $646 million Mega Millions jackpot handed out in March of 2012. “We want to strongly emphasize to everyone to please play responsibly,” said Jeff Anderson, Idaho Lottery director. “Enjoy the games and imagine what you might do if you win, but please only play what you can afford.”

The Powerball tickets can be purchased until 7:55 p.m. Mountain time on Saturday; they cost $2 apiece. Lottery officials encourage ticket buyers to sign their tickets right away; lottery tickets are “bearer instruments,” so whoever signs and presents the winning ticket for payment will get paid.

The largest Powerball jackpot collected by an Idaho winner to date was $220,300 in May of 2005. Powerball is a multi-state game played in all but seven states.
