Read full description

This is a classic digital logic puzzle game. The goal is to fill a 3×3, 6×6, or 9×9 grid so that the numbers 1 to 9 in each row, column, and small nine-square grid are not repeated. The initial state of the game is usually that some squares have been filled with numbers. Players need to use reasoning and logic to gradually fill in the remaining spaces and finally complete the entire puzzle.
