If you can solve Sudoku then you can solve Jigsaw Sudoku, the puzzle with the twisted regions. The regular 3x3 boxes are replaced with all sorts of weird and wonderful jigsaw shapes, each of which is ready and waiting for 1 to 9 to be fitted into it.

There are 100 of these puzzles in this book, each rated 'easy'. All of the puzzles are symmetrical in a wide range of different ways, and every one can be solved without requiring complex logic, so it's suitable even for beginners - but the varied nature of each puzzle means there's a challenge even for experts!
