Tips for Success
• Start with the most constrained cells - look for cells with the fewest possible values
• Use the "scanning" technique - check rows, columns, and boxes to eliminate possibilities
• Try the "candidate listing" method - note all possible values for empty cells
• Look for "hidden singles" - when a number can only go in one cell within a row, column, or box
• Use "pointing pairs" and "box/line reduction" for more advanced puzzles
• Don't guess unless absolutely necessary - Sudoku is a game of logic, not chance
• Practice regularly to recognize patterns and improve your solving speed
