A co-worker recently showed me a really good site for printing off free Sudoku puzzles. The site is thru The Washington Post newspaper. I have never purchased a Sudoku book of puzzles because I’m afraid it would consume my time. Once I start one, I can’t put it down until I have solved it. The other day, my co-worker printed a Sudoku Mega puzzle which is a 4x4 and uses numbers 1-9 and the letters A, B, C, D, E, F and G. I had never seen a MEGA puzzle. After completing the puzzle (3 days later), I didn’t think it was really any harder; it just took longer. To the left is an example of a Mega (4x4) Sudoku puzzle. I also found that there is a MINI Sudoku puzzle which is a 3x2.Another neat game on this site is Kakurko. Kakuro is like a mathematical crossword puzzle: the rows and columns must sum the number above and to the left. If you like numbers, you should try Kakuro. Below is a Kakuro puzzle; as you can see, this one is rated pretty difficult. If you have never tryied one, I would recommend going to The Washington Post site and selecting an easier one or play online until you get the hang of it.
