The Mega Millions jackpot has jumped to $636 million dollars.
The cash option for the jackpot is around $341 million. The near record-setting jackpot was helped in large part due to a change in the way Mega Millions is played.
Players now choose five numbers from 1-75 and one number from 1-15. That change raised the odds from 1 in 176 million to the current odds of 1 in 259 million.
Those long odds are not slowing down ticket sales. Officials say it is still possible that tonight's jackpot could be raised again.
