Sudoku is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid (also called “boxes”, “blocks”, “regions”, or “sub-squares”) contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid which has a unique solution to be solved.

The competition will include:

Classic Sudoku

Killer Sudoku (follows classic sudoku rules but also includes areas which must add up to a given number, without duplicating numbers within the area)

Diagonal Sudoku (the main diagonal must also obey the same rules as rows/columns)

Jigsaw Sudoku (areas have different shapes)
