The rules of Jigsaw Sudoku are similar to standard Sudoku, since you must place each of the numbers 1 to 9 (or 1 to whatever the size of the puzzle is) into each of the rows and columns. However whereas standard Sudoku also has rectangular boxes that must each contain every number, in Jigsaw Sudoku these boxes are replaced by different bold-lined shapes that must each contain every number instead.

The puzzle a 16 x 16 grid made up of 4 x 4 subgrids (called "regions"). Some cells already contain numbers, known as "givens".

Each number in the solution therefore occurs only once in each of three "directions", hence the "single numbers" implied by the puzzle's name.
