Someone in Tuggeranong should have an itchy palm by now after scoring a division one win in Monday's Lotto draw.
The winning ticket was purchased at Lanyon Newsagency in Conder.
The ticket is unregistered so NSW Lotteries have no way of contacting the winner with the life-changing news and must wait for them to come forward to claim their prize.
The mystery winner will take home the guaranteed division one prize of $1 million after Monday's Lotto draw number 3928.
The winning numbers were 13, 23, 10, 11, 8 and 20 while the supplementary numbers were 21 and 40.
Across Australia, there were two division one winning entries in draw 3928, one from Tasmania and one from ACT.
