Be Patient: Intermediate-level puzzles may require a bit of trial and error and backtracking.Use the Process of Elimination: As you fill in more numbers and make progress, revisit the entire puzzle and see if you can spot new possibilities or eliminate numbers from certain cells based on what’s been filled in.They involve identifying patterns of numbers that lead to eliminations in rows and columns. X-Wings and Swordfish: These are more advanced techniques but can be useful in intermediate puzzles.When you eliminate a number as a possibility for a specific cell, remove it from the candidate list for that cell. Candidate Lists: Keep track of the possible numbers for each empty cell in a candidate list (pencil marks).If a number can only go in one row or column within that box, it can be eliminated from the corresponding row or column outside the box. Box-Line Reduction: Look for numbers that are confined to a specific box in a row or column.This is called a “naked triple.” The same principle applies to pairs and quads. Subset Strategy: When you have a group of three cells in a row, column, or box that can only contain three specific numbers, you can eliminate those numbers from other cells in the same row, column, or box.This method helps identify potential candidates. Crosshatching: Focus on one number at a time and look for cells in rows and columns where that number is missing but could potentially go based on the numbers already filled in the boxes and the overall grid.If you find a number that appears only twice in a row, column, or box, you can often determine where it should go. Check Rows, Columns, and Boxes: Examine rows, columns, and 3×3 boxes to see if a number appears twice.This is the most basic and crucial strategy. If you find any, fill them in immediately.

Scan for Obvious Numbers (Singles): Always start by scanning the puzzle for any cells with only one possible number.
