Técnicas de resolución para nivel Difícil
| Técnica | Descripción | Nivel |
|---|---|---|
| Map All 29 Units First | You have 9 rows + 9 columns + 9 irregular regions + 2 diagonals = 29 constraint units. Identify all irregular regions and both diagonals before starting. | Principiante |
| Diagonal–Region Intersection | Cells on a diagonal that also sit in the same irregular region create a powerful two-unit intersection — use both constraints simultaneously. | Intermedio |
| Diagonal Pointing Pairs | If a digit on a diagonal is confined to one irregular region, eliminate it from all other cells of that region. | Intermedio |
| Region Coloring for Diagonals | Trace which irregular regions each diagonal passes through. Regions with many diagonal cells are the most constrained. | Avanzado |
| Chain Deduction Across Units | With 29 units, a forced digit in one unit often cascades through 3–4 other units. Track chains carefully to avoid errors. | Avanzado |

Técnicas para dominar en Difícil
- Hidden Pairs technique — With 29 overlapping houses, candidate counts drop unevenly — recount the diagonal cells after region eliminations, because that's where hard grids hide two digits in two cells.
- Técnica X-Wing — Rows and columns here are classic, so X-Wings work untouched — and any corner that lands on a diagonal exports its elimination into a fourth house.
