The record lottery jackpot was a $1.6 billion Powerball prize won in January 2016.

The previous all-time record for Mega Millions was $656 million for a drawing on March 30, 2012.

The $868 million jackpot refers to the annuity option, paid out over 29 years. The cash option, which is favored by nearly all winners, is $494 million.

Mega Millions’ jackpot has been growing since July, when a group of California office co-workers won $543 million.

Three other Mega Millions jackpots have been won this year – $451 million on January 5 (Florida), $533 million on March 30 (New Jersey), and $142 million on May 4 (Ohio).

It costs $2 to play the game and the odds of matching all six numbers and winning the jackpot is one in 302.5 million.

Mega Millions drawings are held Tuesdays and Fridays at 11 p.m. ET. The game is played in 44 states as well as Washington, D.C., and the U.S. Virgin Islands.
