Unfortunately, they just don't know it yet.

The elusive player secured the guaranteed cash booty in Lucky Lotteries Super Jackpot draw 10332, which was drawn on Wednesday, November 13.

Although the entry is registered to a Players Club card, NSW Lotteries officials have been unable to make contact with the winner.

The entry was purchased at Singleton Discount Drug Store in John Street.

Employee Teymara Dixon said the outlet was hoping the winner would come forward and discover their prize.

"We've been encouraging all of our players to check their tickets," she said.

"We can't wait for them to discover their win.

"We are so happy for them and can only imagine how excited they will be when they finally realise they're the winner.

"It's such great news for our store and we have been celebrating and sharing the news with all of our customers."

NSW Lotteries spokesperson Ally Ramsamy said the Singleton mystery winner could be oblivious to the fact they're holding a winning $100,000 Lucky Lotteries ticket.

"There are one hundred thousand reasons why you should check your tickets today," she explained.

"Imagine how your life would change once you discover you are now $100,000 richer.

"You may not think it's possible you could be the first prize winner we're searching for.

"But, if you purchased a registered entry in last Wednesday's Lucky Lotteries Super Jackpot draw that you haven't checked yet, you're in with a chance.

"Other winners have told us they've found their tickets right in front of their noses stuck on the fridge door, sitting in their wallet or in the car glovebox.

"We're urging all Lucky Lotteries Super Jackpot players who purchased an entry at Singleton Discount Drug Store to check their entries as soon as possible.

"And, if you discover you are holding the winning ticket to contact NSW Lotteries on 131 868 to begin the process of claiming your prize."
