I noticed them first in the newspaper, these nice little number puzzles. Then I found them mentioned on the web, and best of all, I found a place to play online - one new puzzle each day. I am of course talking about Sudoku.

The rules are simple enough - each number must occur only once in a line, a row, and a block. So, it’s just to put in the missing numbers in the puzzle, which has only one solution. Easy, right? Well - while they can be solved by thinking logically and thus requires no guesswork, you still need to keep the tongue straight in your mouth. The difficulty of the puzzles varies with how many numbers are removed from it, roughly speaking. (Well - the hardest ones may require guesswork to lesser or greater degree…)

The article about Sudoku in Wikipedia is great, with many links to pages and tools about the game. If you just want to dive in and start playing online, try these links:
