Want to see something impossible???



March 2006: The generator has been given a serious overhaul. All Sudokus have ONE solution only. All Sudokus are now perfectly symmetrical. A new timer has been added by popular request. Also you can now mark your own hints.
If you choose the ULTIMATE level you will be treated to THE MOST DIFFICULT SUDOKU PUZZLES ONLINE!
