Here are the two files which will give you the ability to play Sudoku by either generating a game or copying it from a printed source. If the printed source has more than one solution, it can show up to 1,000 valid solutions.
The program also gives you hints as to what to do next if you get stuck..
Here is a link to the Sudoku.zip files - Updated 5/11/07 to Version 1.03
Microsoft, in their attempt to protect you against unknown sources of code now blocks programs not know to them. This protection has changed. As of this writing, in order to have both the program and the help features work, you must first download the .zip file to your machine, Then right click on the .zip file and select properties. At the bottom of the properties window, click Unblock. Then say "OK" to exit the properties window and open the .zip file. On the "File" menu (top left) select "Expand All" and follow the instructions to place the files wherever you want them. You may then discard the zip file.
After you start the Sudoku.exe program, put the cursor anywhere on the puzzle, press "F1", and go right to "Getting Started" for a quick introduction.
