Powerball, Mega Millions jackpots swell to nearly $750M

The Powerball and Mega Millions jackpots have swelled to a combined total of nearly $750 million. So is there any advice on how to win big?

With the drawings just hours away, people are buying tickets in an attempt to win the double lotto. Friday's Mega Millions jackpot has reached an estimated $393 million, and the winning numbers for Powerball's $356 million estimated prize will be drawn Saturday.

The odds of winning both games are long, with around a 1 in 75.6 quadrillion chance of hitting it doubly big. Put another way, that's a 0.000000000000000013 percent chance.

And yet the chance is there. Maybe these strategies could help.

Try for Both
You double your chances of winning if you buy both tickets, an Allstate data strategist tells CNN. Of course, your odds still aren't great: The odds of winning Powerball were reported by CNN Thursday as 1 in 292 million, while the Mega Millions odds were only marginally better at 1 in 259 million.

Play the Machine
The owners of a Pennsylvania store that sold a $50 million ticket in 2012 say people should let the machines pick their lottery numbers. The advice follows the destiny approach to playing the lottery.

See if Lightning Will Strike Twice
Maybe it's worth trying your luck at a store that's seen some in the past. ABC's "Good Morning America" notes a Publix supermarket in Melbourne Beach, Florida, sold a ticket last year for part of a record-breaking jackpot of $1.586 billion. The prize was reportedly the largest in lottery history. Shops in California and Tennessee also sold winning tickets in the drawing.

Or there is Fond du Lac, Wisconsin, which is home to a Main Street area that's been called the "miracle mile" and "the luckiest stretch of land in the world" due to so many winning lottery tickets being sold there.

"GMA" says at least 13 winning Powerball tickets have been purchased on the "miracle mile" since 1993.
