Daily Sudoku
Sudoku is a logic-based (not a mathematical) number puzzle that took the world by storm in 2005. Whilst often referred to as a Japanese number puzzle, it is thought that that Sudoku actually derived from Latin Squares, a game known since medieval times.
The recent Sudoku craze was kicked off by New Zealander Wayne Gould when, in 1997, he saw a partially completed puzzle in a Japanese bookshop. Over the next few years he developed a computer program to produce puzzles quickly. He then promoted Sudoku to The Times in Britain, which launched it on 12 November, 2004.
To solve a Sudoku, every number from 1 to 9 must appear in:
- Each of the nine vertical columns
- Each of the nine horizontal rows
- Each of the nine 3 x 3 boxes
When you’ve correctly completed a row, column or box, it will change colour.
Scientific studies have shown that a daily burst of sustained mental activity – such as solving Sudoku puzzles - can help prevent memory loss and degenerative brain disorders such as Alzheimer’s – a very good reason to get your daily dose of puzzling fun at nzwomansweekly.co.nz

Over the Teacups
My four-year-old grandson was at the supermarket with his mother when he exclaimed, “You’re buying something, Mummy, auntie is buying something – I want to buy something!” Mum replied, “You have to be big, have a wife, have a job, then you can buy things.” He replied, “I have a wife – Maia,” meaning his four-year-old friend. Mum said, “What about a job?” Master Four replied, “My job is having a wife!”

Water you want?
I was in the car and asking Master Three what he wanted for Christmas. He said he was going to ask Santa for a water pistol. “And Nanny,” he added, “I’m going to ask for some water for our paddling pool.” Now that could be interesting!

Bee gone
Master Three had his first bee sting recently. The incident broke his heart, but after many cuddles he came right. Later he said, “I never want to see another bee again. I don’t like bees any more, I only like flies.”

Fraud with worry
My daughter warned me that “old people are being taken for a ride,” and that I shouldn’t engage in conversation with phone sales people. To this, Master Five piped up, “Nana can’t go on that ride, she’s old.”
