Two-String Kite

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.

Technique

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.

Tips

• 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.
