Sudoku
I’ve been reading about Sudoku and it sounds like an interesting puzzle. I’ll let Wikipedia explain how it works:
The aim of the canonical puzzle is to enter a numerical digit from 1 through 9 in each cell of a 9×9 grid made up of 3×3 subgrids (called “regions”), starting with various digits given in some cells (the “givens”). Each row, column, and region must contain only one instance of each numeral.
Before this year I had never even heard of Sudoku, now it seems to be everywhere I look… the New York Times, Amazon, and even Freshmeat.
Funny how random things become popular so quickly.
Update: Well, I just completed my first Sudoku. I finished an easy one at Web Sudoku (highly recommended) in exactly 15 minutes. Not a bad little puzzle.
Update 2: Be sure to check out Python Sudoku.
