Jigsaw Sudoku Puzzles
Jigsaw Sudokus (also known as Irregular, Nonomino, or Geometric Sudoku) are very similar to regular Sudoku puzzles, but instead of 3x3 blocks, they are divided into irregular jigsaw-like shapes. Each row, column and jigsaw shape contains all of the digits 1 thru 9. Here's a short tutorial to help you get started on these puzzles.My Jigsaw Sudoku puzzles are collected in 100 printable booklets per volume. Within each volume, the puzzles are also ordered by ascending difficulty. Each booklet contains eight puzzles, hints, and answers.

These puzzles require basic Sudoku strategy. In addition, you may find it helpful to acquaint yourself with the Law of Leftovers.

How to use the hints
My puzzles contain a page of hints in addition to a page of answers.The hints are puzzles grids that contain numbers showing the order in which the squares were solved by the computer. Although this is not necessarily the order you would solve the puzzle, it's probably pretty close.
Follow the numbered squares in order 1,2,3,4,5... until you find a square you haven't solved yet. This square (or the one or two immediately after it) is a good candidate to solve next.
