Sudoku Challenges
Sudoku Challenges is a logic based combinatorial number placement puzzle. The goal is to fill a 9 × 9 grid with digits so that each column, each row, and each of the nine 3 × 3 subgrids that make up the grid (also called boxes or blocks) contain all the digits from 1 to 9. Each puzzle will start on a partially completed grid, which has only one solution.
