How to Solve This Puzzle
Solving a medium Sudoku puzzle requires a blend of basic techniques and strategic thinking. Begin by scanning for Naked Singles, which are cells with only one possible number. This is your foundational step, as identifying these numbers simplifies the grid significantly. Next, look for Hidden Singles within rows, columns, and boxes. These numbers might not be immediately obvious but are the only option for a particular cell within a unit. Once you've placed the easy numbers, employ Box/Line Reduction. This technique involves scanning the interaction between rows, columns, and boxes. If a number must appear in a specific row or column within a box, eliminate it from other possibilities in that row or column. Another technique to consider is the use of Pencil Marks. Write possible numbers in each cell to visualize potential solutions. This method helps in spotting Naked and Hidden Pairs or Triples, which can further reduce possibilities. Remember, patience and consistent practice are key. As you work through the puzzle, double-check each move to avoid errors. With these strategies, you'll efficiently solve today’s medium Sudoku.
