Convenience stores have been busy selling tickets and advertising that big number.
Store owner Kim Tinner says business at the store always picks up after powerball hits the 200 million mark, but she often notices a different kind of customer when the number creeps that high.
"We are seeing a lot more people, the offices are getting their money together and they will all collectively go in," Tinner says. "So you start seeing a lot bigger purchases instead of the single tickets."
Tinner says it's not uncommon for the office pools to buy more than 100 tickets at a time.
If you think you're going to be the big winner, tune in tonight after the Olympics to see the numbers.
