Solution


Sudoku puzzles come in varying levels of difficulty. Several factors determine the difficulty of a puzzle. Generally speaking, the number of logical decisions and techniques required to complete the puzzle makes the puzzle more or less difficult. Easy puzzles can usually be solved quickly by scanning the row, column, or square for missing numbers. As puzzles get more difficult, more logical decisions are required, and less immediately solvable clues are available.
