Techniques de résolution pour le niveau Expert
| Technique | Description | Niveau |
|---|---|---|
| Region Identification First | Identify all 9 irregular regions by their colour coding before solving. Region membership determines the third constraint unit for each cell. | Débutant |
| Region Counting | Each region must contain 1–9. Counting completed rows and columns reveals how many of each digit can still fit in each region. | Intermédiaire |
| Region–Row/Column Intersection | If a digit within a region is confined to one row or column, eliminate it from the rest of that row or column. | Intermédiaire |
| Irregular Naked Subsets | Apply naked pairs and triples within each irregular region exactly as you would within standard 3×3 boxes. | Avancé |
Techniques à maîtriser au niveau Expert
- Technique X-Wing — Expert jigsaw grids exploit the law-of-leftovers along region borders; once line logic stalls, fall back to X-Wings on rows and columns, which ignore region shapes entirely.
- Swordfish technique — Because regions can't be trusted to behave like boxes, expert jigsaw endgames lean on pure line-based fish — a Swordfish here needs no region reasoning at all.
