Someone who paid a visit to Romsey IGA on Saturday has hit the jackpot and they don’t know it.

Tatts is searching for the lucky winner who won $1.5 million but is yet to come forward.

A TattsLotto ticket bought at Romsey Supa IGA Newsagency & Lotto on Main Street on Saturday, February 10 is the key to the division one prize from the TattsLotto draw 3815.

The entry is not registered to a Tatts Card, meaning officials do not have a way to contact the winner.

Tatt’s Bronnie Spencer has encouraged all Romsey TattsLotto players to check their tickets.

“You may not think it’s possible that you could be one of the division one winners we’re searching for, but if you purchased an unregistered entry in the weekend’s TattsLotto draw that you haven’t checked, you’re in with a chance,” Ms Spencer said.

The six winning numbers in draw 3815 were 7, 27, 23, 2, 16 and 44. The supplementary numbers were 25 and 28.

“If you discover you are holding the division one winning ticket contact Tatts on 131 868 to begin the process of claiming your prize.”
