Those people clogging up the line at the convenience store cash register are there for good reason:  The Powerball jackpot is up to $337 million. That's about $209 million if you take the cash option.

If a Michigan player win’s Saturday’s $337 million jackpot, it would equal the largest Powerball prize won in the state. On Aug. 15, 2012, Donald Lawson, of Lapeer, won a $337 million Powerball jackpot. Lawson’s jackpot holds the record for the largest Lottery prize ever won in Michigan.

You haven until 9:45pm Saturday to plunk down your two bucks for each Powerball ticket and there's absolutely no way to win unless you buy at least one. You can buy online at MichiganLottery.com .

A “Power Play” option that multiplies non-jackpot prizes by up to 10 times to a maximum of $2 million may be added to any Powerball play for only $1.

The Powerball drawing takes place at 10:59 p.m. and may be watched live online at: http://www.powerballlive.com/powerball. Powerball tickets are sold in 44 states, Washington D.C., U.S. Virgin Islands, and Puerto Rico.
