How to Master the XYZ-Wing Strategy in Sudoku<\/strong><\/h1>\n\n\n\n

When your puzzle demands deeper candidate reduction than a standard XY-Wing<\/em> can offer, it is time to upgrade your scanning toolkit. The XYZ-Wing technique<\/strong> is an advanced expert strategy. This is an extension of the XY-Wing, but now it contains not only X and Y candidates, but Z as well.<\/strong><\/p>\n\n\n\n

By leveraging a trio of cells where the main “pivot” cell contains three digits instead of two, you can safely strip away stubborn candidates from intersecting cells.<\/p>\n\n\n\n

The Structure of an XYZ-Wing<\/strong><\/h2>\n\n\n\n

To locate an XYZ-Wing pattern on the grid, you need to find three interconnected cells<\/strong> that share a total pool of three candidate numbers (which we label X<\/strong>, Y<\/strong>, and Z<\/strong>):<\/p>\n\n\n\n

Consider these cells:<\/p>\n\n\n\n

  1. The Pivot (Base Cell):<\/strong> Contains all three candidates: 2, 3 and 4<\/li>\n\n\n\n
  2. Wing 1:<\/strong> Shares a unit (row) with the Pivot and contains two of those candidates: 2 and 8<\/li>\n\n\n\n
  3. Wing 2:<\/strong> Shares a column with the Pivot and contains the other two candidates: 2 and 3<\/li>\n<\/ol>\n\n\n\n

    Notice that the digit 2 is the common thread running through all three cells!<\/p>\n\n\n\n

    The Logic Behind the Elimination<\/strong><\/h2>\n\n\n\n

    Because of how the numbers are distributed across the Pivot and its two Wings, we reach an absolute mathematical lock:<\/p>\n\n\n\n
