The estimated $940 million jackpot has been growing for more than two months and now ranks as the sixth-largest in U.S history.
Friday's winning numbers are 3, 20, 46, 59, 63 and 13.
Even as the prize grows larger, the odds of winning remain the same at one in 302.6 million.
The $940 million jackpot is for winners who choose an annuity, paid annually over 29 years. Winners usually want cash, which for Friday night's drawing would be an estimated $483.5 million.
If there is no winner, the next drawing will be held Tuesday night.
Mega Millions is played in 45 states as well as in Washington, D.C., and the U.S. Virgin Islands.
