Teknik Pemecahan untuk Tingkat Ahli
| Teknik | Deskripsi | Level |
|---|---|---|
| Negative Constraint | Where no X or V appears between adjacent cells, their sum is neither 10 nor 5. This eliminates (1,9), (2,8), (3,7), (4,6) for X and (1,4), (2,3) for V. | Pemula |
| Sum Pair Enumeration | List all digit pairs that sum to 10 (for X) or 5 (for V), then use row/column placement to identify which pair must occupy each marked pair. | Pemula |
| Marker Chain Logic | Multiple consecutive X and V markers in a row form a sum chain — enumerate valid assignments for the entire chain simultaneously. | Menengah |
| Box X-Interaction | An X pair forces both digits into specific positions within their shared box, constraining all remaining cells of that box. | Lanjutan |
Teknik untuk Dikuasai di Ahli
- Teknik X-Wing — Expert XV solving alternates marker chains with fish — push the negative constraint until a digit holds two cells per row, then the X-Wing finishes the line.
- Swordfish technique — Dense marker chains leave mid digits clustered in matching columns; a Swordfish on 5 — the marker-immune digit — cracks many expert XV endgames.
