The Massive Book of Jigsaw Sudoku: 1000 puzzles (Jigsaw Sudoku Puzzle Books: The Irregular Matrix Series)

Welcome to volume 2 of the largest collection of Jigsaw (or irregularly shaped) Sudoku puzzles!
Who would've thought that 1000 irregularly shaped sudoku puzzles wouldn't be enough! Volume 1 has had such a great reception that I simply had to publish a new volume.

Contents:
• 1000 Jigsaw 9x9 Sudoku (squiggly, irregularly shaped) puzzles
• 5 levels of difficulty
• all solutions
• all solving techniques explained with examples!

The only difference between Sudoku and Jigsaw puzzles is that the 3x3 squares are no longer squares; instead they are irregularly shaped, like pieces of a jigsaw puzzle. Each puzzle has a unique squiggly design and so they never become boring.
In this book there are 1000 of these puzzles in 5 levels of difficulty. All puzzles have one solution only, which can be reached without guessing.
Solving techniques are explained in the introduction, including the "The Law of Leftovers" solving method, which is authentic for Jigsaw Sudokus.
HAVE FUN!
