Do You SuDoKu?

Scientists have identified Sudoku as a classic meme - a mental virus which spreads from person to person and sweeps across national boundaries. Susan Blackmore , author of The Meme Machine, said: “This puzzle is a fantastic study in memetics. It is using our brains to propagate itself across the world like an infectious virus.”

For the uninitiated, Sudoku is a puzzle that requires you to complete a 9-by-9 grid of 81 cells so that every row, every column, and every 3x3 box of cells contains the digits 1 through 9. Some of the cells are pre-filled – making the puzzle easier (or harder!) Try it, and you are likely to be captivated by this craze.
There are claims – unsubstantiated, so far – that sudoku-ing will delay the onset of Alzheimer’s. Doubtless, clinical studies are under way. The next world championship will be held in Lucca, Italy, this summer. If you don’t sudoku, but your spouse does (as in my case), consider attending. Lucca is a charming walled city in Tuscany , home of excellent olive oil, wine, and Puccini . Verdi lived nearby, and Florence is only an hour or so away. Lots to do, even if you don’t sudoku.
