I have dishonored my neurons and will now commit sudoku
In the UK, a new type of number puzzle is apparently all the rage: sudoku. This game, invented in North America 25 years ago, migrated to Japan where it got its current name. It then crossed the globe again to the United Kingdom and is becoming a regular feature in many newspapers there.
The rules of the game are simple: You are presented with a 9x9 grid of squares, divided into 9 boxes of 3x3. Some of the squares have numbers in them. Your task, young Jedi, is to fill in the remaining squares so that the whole grid obeys the following rules:
- Each square contains a digit from 1 through 9
- No row of the grid has the same digit twice
- No column of the grid has the same digit twice
- No 3x3 box has the same digit twice
If this sounds easy, think again. You can find sudokus at The Sudoku Site and get a fresh one every day at The Daily Sudoku. Enjoy your sudoku but go easy on the wasabi.
