App Profile: Number Place Game

The Number Place Game is a logic-based, combinatorial number-placement puzzle. In the classic Number Place Game, the goal is to populate a 9 × 9 grid with digits in such a way that every column, every row, and each of the nine 3 × 3 subgrids that make up the grid (also known as "boxes," "blocks," or "regions") contains all the numbers from 1 to 9.
