How to play
Every row and every column contains 1 to 9 once. Instead of 3×3 boxes, the grid is divided into nine shapes of nine squares with thick borders, and each shape also contains 1 to 9 once.
Jigsaw sudoku is also called irregular sudoku. The shapes change from puzzle to puzzle, so look at each shape as you would look at a box.
