Jigsaw Sudoku Puzzles by Dr Gareth Moore

Jigsaw Sudoku Jigsaw Sudoku is a traditional Sudoku puzzle where the 3-by-3 box regions have been replaced by irregular jigsaw-shaped regions, all of the same size. In all other respects it works in the same way, but this change in the region shapes introduces new twists into the logic required to solve the puzzle. The aim is simple: place the digits 1 to 9 into the puzzle grid so that each digit occurs once in every row, column and bold-lined jigsaw-shaped piece. Some digits might already be given - these constrain the puzzle in such a way that there is only one possible solution, which can always be reached via reasonable logical deduction. Guessing is never required. I can supply Jigsaw Sudoku (also known as Irregular Sudoku) puzzles in any size and with a range of possible variations - from Jigsaw Sudoku-X through to more unusual varieties such as Jigsaw Skyscraper Sudoku(!). All of my puzzles are either entirely hand-made or have significant manual input into the process.
