What is the XYZ Wing?
The XYZ Wing is an advanced elimination technique that combines elements of both the X-Wing and Y-Wing patterns. It's named "XYZ Wing" because it involves three cells (X, Y, and Z) that form a specific relationship allowing for candidate elimination.
Key Characteristics of XYZ Wing:
- Three-cell pattern: Involves exactly three cells in specific positions
- Shared candidates: The three cells share common candidate numbers
- Elimination power: Can eliminate candidates from cells that see all three XYZ Wing cells
- Advanced technique: Requires mastery of basic elimination methods first
XYZ Wing Structure
Cell X: Contains candidates A and B
Cell Y: Contains candidates B and C
Cell Z: Contains candidates A, B, and C
When these three cells are positioned correctly and share a common unit (row, column, or box), they form an XYZ Wing that can eliminate candidate B from other cells in the shared unit.
