About this game
An addictive logic-based, combinatorial number-placement puzzle game. 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" or "blocks") contain all of the digits from 1 to 9. Each puzzle will start at a partially completed grid, which has a single solution.
