Técnicas de resolución para nivel Experto
| Técnica | Descripción | Nivel |
|---|---|---|
| Clue 1 Forces 9 First | A visibility clue of 1 means the first building from that edge must be a 9. All shorter buildings behind it are hidden. | Principiante |
| Clue 9 Forces Ascending Order | A clue of 9 means all buildings are visible, so digits are in strictly ascending order from that edge: 1, 2, 3, 4, 5, 6, 7, 8, 9. | Principiante |
| Permutation Enumeration | For each clue value V, enumerate all permutations of 1–9 that give exactly V visible buildings. Cross-reference opposite-edge clues. | Intermedio |
| 9 Always Visible | The digit 9 is always visible from either edge. The digit 8 is visible only if it appears before any 9 from that edge. | Intermedio |
| Multi-Edge Constraint | Combine the clue from one edge with the opposite edge's clue. Both must be simultaneously satisfiable. | Avanzado |
Técnicas para dominar en Experto
- Técnica X-Wing — Expert skyscraper grids leave the tall digits ambiguous between exactly two cells per line — the X-Wing on 9 is less a trick here than the intended mechanism.
- Swordfish technique — Opposing clue pairs synchronise 8's possible columns across three rows at a time; the expert endgame usually closes with a Swordfish on 8 or 7.
