Well over half a billion dollars is up for grabs this Tuesday, as the Mega Millions jackpot continues to accumulate over three and a half months.

The $650 million is the tenth-largest jackpot in Mega Millions history, since the game began in 2002. The cash payout for the winner would be $304.1 million.

Tuesday's drawing marks the 33rd for the jackpot run that began following "the last big win in Virginia on June 27," according to a Mega Millions press release. 

"It continues growing after no ticket matched all six numbers drawn Friday night – the white balls 9, 21, 27, 48 and 56, plus the gold Mega Ball 10," the press release said.

The last time a top-10 jackpot was seen was December, when the prize reached $1.269 billion. 

Mega Millions also says a "game change last April has led to hundreds of millions of dollars more paid in non-jackpot prizes compared to the old prize structure."
