Lösungstechniken für Experte-Level
| Technik | Beschreibung | Level |
|---|---|---|
| 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. | Anfänger |
| 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. | Fortgeschritten |
| Diagonal Pointing Pairs | If a digit on a diagonal is confined to one irregular region, eliminate it from all other cells of that region. | Fortgeschritten |
| Region Coloring for Diagonals | Trace which irregular regions each diagonal passes through. Regions with many diagonal cells are the most constrained. | Fortgeschritten |
| 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. | Fortgeschritten |
Zu meisternde Techniken auf Experte
- X-Wing-Technik — Expert grids in this combined variant stall region logic deliberately — fall back to line-based fish, then re-run diagonal and region scans after each elimination.
- Swordfish technique — A Swordfish whose columns cross both diagonals propagates into the densest cells of the grid — expert irregular-diagonal endgames are sequenced around this cascade.
