In all other respects the puzzle works in the same way, but this change in the region shapes introduces new twists into the logic required to solve the puzzle - and often makes it much harder for you to find the next move as a result! Every Jigsaw Sudoku puzzle only ever has one possible solution, and it can always be reached via reasonable logical deduction. In other words, guessing is never required.
