Two-String Kite uses a row and column that share a box to make eliminations.
Understanding the Concept
A candidate appears exactly twice in one row and exactly twice in one column.
The row and column share one box (the "body" of the kite).
The other occurrences are the "strings" of the kite.
Creates a strong inference chain.
Eliminates from cells seeing both string endpoints.
Named for its visual appearance when drawn.
Another turbot fish pattern, like Skyscraper.
Examples
Kite Example
Digit 6 in row 3 (R3C2,R3C8) and column 2 (R3C2,R7C2). Cell R7C8 sees both "strings" and cannot be 6.
Pro Tips
- •Find a row and column with candidate twice each
- •They should share exactly one position
- •Look for eliminations seeing both endpoints
- •Visual pattern - draw it out to see the kite
