A friend of mine at work taught me how to play Sudoku. Now I'm totally hooked!
Start with a puzzle that has some of the cells filled. Then find the solution which fills each empty cell with a number 1 through 9 in such a way that ALL of the following are true:
1.) Each row has just one of each number 1 through 9.
2.) Each column has just one of each number 1 through 9.
3.) Each block (dark gray lines) has just one of each number 1 through 9.
The one above is considered "medium" difficulty. How fast can you solve it?
By the way, I programmed a Caché routine to solve Sudoku puzzles. It kind of takes the fun out of it, though.
