An irregular sudoku PDF, called "jigsaw sudoku", is a sudoku grid composed of nine irregular regions each containing nine squares. The principles of resolution are identical to those of a regular puzzle. The grid must be completed with nine digits in each line, column and irregular region.

You are offered 80,000 PDF, exposed with two structures and four degrees of difficulty.
 •Structures: Symmetrical and asymmetrical.
 •Degrees of difficulty: Beginner, confirmed, expert and extreme.

The PDFs of the first three degrees are solvable with a succession of logical arguments.
PDFs of so-called "extreme" degree will impose multiple choices

To discern irregular areas, you can choose from four types of backgrounds:
  •   White background.
  •   Hatched background.
  •   Shaded background.
  •   Colored background.
