They're more fun as they get harder--you can't really take pride in solving one that has 80% of the numbers filled in but when the whole board only has eight or nine numbers to start you feel smart when you solve it.

What I lack in creativity, I make up for in repettivity.

Here's how to give you a little more respect for SuDoku: I challenge you to write a computer program to solve any SuDoku puzzle ? easy, hard, very hard, whatever (as long as it's solvable)!

9x9 sudoku only? Are we writing a program for elegance or will any program do? Just brute force it. It's only 9!x9! combinations possible, and when you start out with a few starting positions, I'm sure that number comes way down. And a few more easy rules to get started....oh wait, I'm sounding like acomputer geek...why would you want to write a program to do that?

The problem is divising the test to see if your programs solution is both correct and unique.

You would want to write such a program in order to test whether a given SuDoku is solvable, or to generate new puzzles. Writing such a program was the first thing Wayne Gould did before he brought SuDoku to the London Times in 2004. It took him several years to develop such a program.

OK, computer geek, let's see your code!

As Chompy said, Sodoku (the full name of this puzzle translates roughly to "the numbers must be unmarried", by the way) get more interesting the harder it is. :)
