المتطلب السابق: Single-Digit Patterns

Overview

Two-String Kite uses two conjugate pairs for a single digit, with one pair in a row and one in a column, linked through a shared box. The candidate can be eliminated from cells seeing both string endpoints.

How It Works

  1. Find a conjugate pair (exactly 2 occurrences) of a digit in a row.
  2. Find another conjugate pair of the same digit in a column.
  3. The pairs must link in one box (share a cell or have cells in the same box).
  4. Eliminate the candidate from cells that see both outer endpoints.

Example

Digit 7 appears exactly twice in row 9 and exactly twice in column 1.

Tips & Patterns

  • The "kite" is formed by the linking box, and the "strings" are the row and column conjugate pairs.
  • Both endpoints of the strings are in different boxes.
  • Look for digits appearing exactly twice in both a row and column.
