Técnicas de resolución para nivel Experto
| Técnica | Descripción | Nivel |
|---|---|---|
| Global Candidate Pruning | For every filled cell, remove its ±1 neighbours from all orthogonally adjacent cells immediately. | Principiante |
| Digit 5 is Most Constrained | 5 cannot be adjacent to 4 or 6. Use this to restrict placement of 5 across the entire grid. | Intermedio |
| Chain Propagation | Placing a digit propagates constraints along rows and columns, often triggering a cascade of forced placements. | Intermedio |
| Forbidden Pair Maps | Build a map of forbidden digit pairs for each adjacent pair of cells and use it to eliminate candidates systematically. | Avanzado |
Técnicas para dominar en Experto
- Técnica X-Wing — At expert level every placement triggers a board-wide ripple — fish patterns assemble and dissolve as the cascade runs, so re-scan for X-Wings after each ripple completes.
- Swordfish technique — Digit 5, hemmed in by both 4 and 6 everywhere, has the sparsest candidate map on the grid — the expert endgame Swordfish almost always swims on 5.
