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 .

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: Powerball tickets are sold in 44 states, Washington D.C., U.S. Virgin Islands, and Puerto Rico.
