Overview

UVWXYZ-Wing is a six-cell wing pattern with six combined candidates. It extends the wing family to larger sets, using ALS-like logic for eliminations.

How It Works

  1. Find six cells whose combined candidates use exactly six digits.
  2. A pivot cell sees all five wing cells.
  3. The restricted candidate is locked within the pattern.
  4. Eliminate it from cells outside the pattern that see all relevant cells.

Example

Found a 6-Y-Wing pattern. The pivot cell R2C6 has candidates connected to a 5-cell wing group.

Tips & Patterns

  • UVWXYZ-Wings are extremely rare in practice.
  • They are part of the N-Y-Wing generalization where N cells have N candidates plus a pivot.
  • Understanding ALS theory helps recognize these patterns.
