A near $1 million X Lotto prize has gone unclaimed for a month, with the mystery Adelaide winner still to come forward.
SA Lotteries says the $980,293 first-division prize dates back to December 15 but as the entry wasn't registered there's no way to contact the winner.
The ticket was purchased at the Lotteries Kiosk in Adelaide's Arndale shopping centre.
Owner David Nicholas said he was eager to break the good news to the lucky player.
"Plenty of customers have been coming in to see if it is them, while others have been speculating about who it might be," he said.
"Whoever it is, I hope they check their ticket soon and claim their prize so they can start to enjoy it."
Bronwyn Spencer from SA Lotteries said the unclaimed prize could be life-changing.
"Our winner could be completely unaware that they are now over $900,000 richer," she said.
"Imagine how your plans for 2019 would change if you discovered your bank account will balloon by hundreds of thousands of dollars."
