TUVWXYZ-Wing
Level 11 · Red Belt
Overview
TUVWXYZ-Wing is a seven-cell wing pattern, extending the wing family further. Seven cells with seven combined candidates allow elimination of a restricted candidate.
How It Works
- Find seven cells whose combined candidates total exactly seven digits.
- A pivot cell connects to six wing cells.
- Identify the restricted candidate forced within the pattern.
- Eliminate it from cells seeing all relevant pattern cells.
Example
Found a 7-Y-Wing pattern. The pivot cell R9C8 has candidates connected to a 6-cell wing group.
