X-Wing in Sudoku: learn to recognize the advanced pattern
An X-Wing is a relationship between candidate positions across distant rows and columns. The shape can look convincing before it is valid, so the important skill is proving the pattern rather than spotting a rectangle.
Included with Coaching
The interactive lesson builds the pattern one check at a time, tests it against near misses, and asks you to make the final elimination on a fresh grid.
- Follow one candidate across a full grid without losing the relevant positions.
- Test every condition before treating the shape as an X-Wing.
- Choose a safe elimination on a new grid without an answer reveal.
