A lucky George Town shopper, one of 17 winners, will receive a $1.3 million share of Saturday night's $23.3 million jackpot.

Songwriter Stevie Wonder might say the writing is on the wall for the store, which celebrated its six-year anniversary on Saturday and has just completed new renovations.

The outlet also saw a division 2 winner last month and has celebrated a host of division 3 successes in the past years.

Owner Sue Sherriff said they kept a series of good luck charms about the shop to try and improve winning chances.

``We were joking all week that a change of luck is happening here with all our new changes, we're absolutely ecstatic,'' Ms Sherriff said.

``We work with our Buddhas, feng shui and we keep a bag of coins and a red ribbon under the mat.

``Everyone is encouraged to think positive.''

She said they did not know who won and urged the buyer of the winning Tattslotto ticket to contact the organisation directly to maintain their privacy.

``The store doesn't get anything for having winners, we just love the fact that one of our customers has had a change of luck,'' Ms Sherriff said.

A Prospect Lotto shopper scored a $1 million win in a Superdraw last July - only a month after another customer won $514,449 from the outlet.

A Latrobe footballer snagged $1.5 million in a September Superdraw last year and a Launceston couple had a $1.5 million Tattslotto windfall in October, 2011.
