Sudoku and Other Diversions

My wife, having been told by friends in Europe that Sudoku, the Japanese [1] number-grid puzzle, was all the rage there, asked me to find some Sudokus and teach her how to solve them. A Google search disclosed a website with billions of Sudoku puzzles, a Wikipedia article with the puzzle’s history and mathematics, and dozens of other sites which (as the little girl wrote in her book report) “told me more than I wanted to know.”

I tried a few Sudokus and found that they could be solved by logical inference without any guesswork. My wife caught on to the method quickly and is now happily puzzling away.

A very good article on other diversions other than sudoku, for people who cannot get their fix on Sudoku
