How to Solve This Puzzle
Solving a medium Sudoku puzzle like today's requires a mix of basic and intermediate strategies. Begin with the Naked Singles technique, where you identify cells that can contain only one possible number. Scan each row, column, and grid to spot these opportunities. Once the obvious placements are made, turn your attention to Hidden Singles. This involves finding the only possible location for a number within a row, column, or 3x3 box, even if other candidates are still present in the grid. As you progress, employ Box/Line Reduction, which is essential in medium puzzles. This technique helps eliminate possible numbers in a row or column by focusing on intersections with 3x3 boxes, effectively narrowing down possibilities. Be methodical: start from one corner of the grid and work systematically across, revisiting sections with new insights gained from other areas. Keep a pencil handy for noting potential numbers in cells, known as pencil marks, which can guide your further deductions. By practicing these strategies regularly, you'll improve your speed and accuracy, turning medium puzzles into enjoyable and rewarding challenges.
