Jigsaw sudoku puzzles make a nice twist on the traditional format. Just as in a regular sudoku, the rows and columns must still contain one and only one of the digits. However, as you can see, instead of the usual regularly shaped subareas, known as nonets, the boxes are irregularly shaped. Just as in a standard sudoku, you may only put one of each of the digits in these subareas.
These puzzles can get your mind working in some interesting new ways.
If you are just getting started with sudoku, you might want to ease your way in with something a bit more traditional. Train first with these Easy Sudoku Puzzles.
