A "classic" Sudoku puzzle is a grid 9 squares wide and 9 squares deep. The lines of squares running horizontally are called rows, and the lines running vertically are called columns. The grid is further divided by the darker lines into nine 3 X 3 square "boxes".

The Challenge: Some of the squares already have numbers in them. Your task is to fill in the blank squares.

The Rules:

  1. Each row, each column and each box must end up containing all of the numbers and/or characters used in the puzzle (in this example the numbers 1 through 9 are used).

  2. Each number and/or character can only appear once in a row, column or box.

You need Java enabled to view the crossword applet.

If you do not have Java installed you can obtain it from java.com. If do have Java you may need to check your security settings to make sure that applets are enabled, especially if you are viewing the puzzle from your hard disk. In Windows XP you may be able to enable the applet by clicking on the yellow bar at the top of the window and selecting "Allow blocked content".
