What is the X-Wing Technique?
The X-Wing is a logical elimination technique that operates on the principle that if a digit can only appear in two positions in two different rows (or columns), and these positions align perfectly, then that digit cannot appear anywhere else in those same columns (or rows).
Why It's Called "X-Wing"
The name "X-Wing" comes from the visual pattern created when you connect the four cells with lines - it resembles the iconic X-Wing fighter from Star Wars, with two diagonal lines crossing in the middle.
X-Wing Visual Pattern
The four cells form a rectangular pattern where:
- Two cells are in the same row
- Two cells are in the same column
- All four cells share the same candidate digit
- The pattern creates an "X" when connected
