That’s some return on investment: Rock Hill woman hits it big with a lottery double.

If at first you succeed, win-win again.

A Rock Hill woman doubled up on her good luck and scored a 16,000-times-over return on investment when she scratched off a winning ticket.

According to the South Carolina Education Lottery, the woman won $15 playing the lottery. She took those winnings and bought another ticket. That In the Green scratch-off bought at Gee Gees Food Store on Saluda Street in Rock Hill won a top prize of $250,000.

According to lottery officials, who didn’t give the woman’s name, she cried after the big win and then slept with the scratch-off ticket stuffed under her mattress.

Gee Gees received a $2,500 commission for selling the winner. Odds of a top prize for In the Green is one in 780,000. One top prize of $250,000 remains in the game.

The Rock Hill woman isn’t the first in the tri-county area to win big. In December a Lancaster man claimed a $250,000 winner. A Rock Hill store sold a $300,000 winner in October. Five York, Lancaster and Chester County big winners since the fall combined, even prior to the most recent win, for almost $1.2 million.

So far this year, there have been 20 tri-county wins at $500 or more.
