I never thought my visit home would include getting hooked on the addictive puzzles known as Sudoku. At first glance it looks like they require a lot of math, but they don’t take a single bit of addition, subtraction, or any more complex tricks. The purpose is simply to place the numbers 1-9 in each 3×3 square, as well as each row and column. Each number, 1-9, should appear only once in a row, column or 3×3 square. Sounds easy enough, doesn’t it? Think of it like a crossword puzzle without having to know any of those annoying words. Pure logic, baby.
Exercise your brain by heading to Web Sudoku. I recommend printing out the harder ones to do with a pencil and eraser. You’ll need it.
