STUVWXYZ-Wing

Level 11 · Red Belt

Prerequisite: WingsLearn next → TUVWXYZ-Wing

Overview

STUVWXYZ-Wing is the largest wing pattern, using eight cells with eight combined candidates. This is the theoretical maximum for the wing family in a 9x9 Sudoku.

How It Works

  1. Find eight cells whose combined candidates use exactly eight digits.
  2. A pivot cell connects to seven wing cells.
  3. The one restricted candidate must be in the pattern.
  4. Eliminate it from cells seeing all relevant pattern cells.

Example

Found a 8-Y-Wing pattern. The pivot cell R6C3 has candidates connected to a 7-cell wing group.

Tips & Patterns

  • STUVWXYZ-Wings are the theoretical limit of the wing technique family.
  • In practice, these are vanishingly rare and primarily of academic interest.
