Lottery officials say they are increasing the MegaMillions lottery jackpot to $640 million, raising what was already a world-record prize.

Kimberly Starks, a spokeswoman for the Georgia Lottery, said Friday the jackpot had increased. The jackpot had stood at $540 million before Friday’s announcement. The previous record jackpot was $390 million in 2007.

A drawing for the fortune is set for 11 p.m. Friday in Atlanta.

The odds of winning the jackpot had been set at about 1 in 176 million.

MegaMillions has drawn long lines of lottery players in stores in Kansas and 41 other states plus Washington, D.C., and the Virgin Islands where tickets are sold. The world-record jackpot has also lured some residents to travel to other states to buy $1 tickets.
