DETROIT (WWJ) - The biggest lottery jackpot in world history, a whopping $1.6 billion, is up for grabs Tuesday night -- and Michiganders are feeling lucky.

According to officials with the Michigan Lottery, Michigan players had already bought 7.4 million Mega Millions for the drawing by 4 p.m. Tuesday.

That included more than 3.2 million purchased on Tuesday alone, at an average of 325,000 tickets per hour. The peak hour for purchases thus far was from 3 p.m. to 4 p.m., when players bought about 10,000 tickets per minute.

Mike Maclin of Detroit says he'll buy a $10 million mansion if he wins.

"Five-car garage, let's see...I'd have maybe eight bedrooms, just 'cause I could have that," Maclin said. "It'd just be a big house. Pool, tennis court, basketball court, it would be huge."

A local woman, who didn't give her name, said she'd spread the wealth. "I'm gonna take care of all of us; we're all gonna be millionaires!" she said. "Why be a millionaire by yourself, right?"

Players have until 10:45 p.m. Tuesday to buy tickets in stores or online at MichiganLottery.com, at $2 a pop.

Some figures to keep in mid about the record jackpot:

The cash option is $913.7 million. The net after tax withholdings would be about $656 million

That cash option alone would rank as the third-largest lottery prize in U.S. history.

The jackpot amount is based on an escalating annuity: An initial payment, then 29 annual payments

With the annuity, payment No. 1 would about $24 million and payment No. 30 would be about $99 million

The odds of matching all six numbers to win the big prize are 1 in 302.5 million

If there is no winner Tuesday, Friday’s jackpot is projected to be $2 billion, Lottery officials said. The cash option would be $1.1 billion with the net after tax withholdings of $820 million.

The previous record jackpot for the U.S. and the world was a $1.586 billion Powerball jackpot won on Jan. 13, 2016.
