CNN-- Louise White, 81 of Newport, R.I. came forward Tuesday as the winner of the $336.4 million Powerball jackpot.
The prize was the biggest ever in Rhode Island and the third biggest in the games history.
Later that evening over a bowl of rainbow sherbert, White said she watched the drawing and wrote down the numbers.
"I decided later to check my ticket," White said. "I yelled, I got that one, I got that one, I got that one."
White can decide to choose the lump sum payment of $210 million or 30 annuity payments paid out over 29 years.
"We will determine in the coming months how we'll spend the money, but we know we'll always have rainbow sherbert."
