Mrs Chelton and her husband Jeff began playing with words competitively in the 1980s in Sydney, and soon after founded an Illawarra club - Wollongong Order of Really Dedicated Scrabblers (WORDS).

The pair used to play at least 1000 games a year between themselves, and always took a Scrabble board wherever they went.

"We went to America once and took our little travel Scrabble with us and played on the edge of the Grand Canyon, we played in New York's skating rink at Central Park, we played on the edge of Niagra Falls," Mrs Chelton said.

"Anytime you play anywhere, people come up and talk to you."

Mrs Chelton said when playing to win it's best to try and maximise your score by putting the highest value tiles on squares of high value. Words such as "cazique" or "za" and "zo", she said.

Her main strategy, is to "score the best you can".

"I don't have a magic formula, I'm just a tough, old player," she laughed.

While winning runs in the family. Her eight-year-old grandson is off to San Diego in June to compete in a world golfing championship - which some of her Scrabble winnings will be used to help out.
