Løsningsteknikker for Ekspert niveau
| Teknik | Beskrivelse | Niveau |
|---|---|---|
| Candidate Scanning | Start by scanning rows, columns, and boxes — any candidate appearing in only one cell in a group must be placed there. | Begynder |
| Cross-Hatch Elimination | When a digit is placed (or reduced to one candidate), eliminate it from all cells in the same row, column, and box. | Begynder |
| Nøgne enere | A cell with only one remaining candidate is a naked single — the digit is forced. In Sukaku, this happens automatically when you eliminate down to one candidate. | Mellemniveau |
| Skjulte enkeltcifre | A candidate that appears exactly once in a row, column, or box must be placed in that cell regardless of how many other candidates that cell shows. | Mellemniveau |
| Pair Elimination | Two cells in a group that share only the same two candidates form a naked pair — both candidates can be eliminated from all other cells in that group. | Avanceret |
Teknikker at mestre på Ekspert
- X-Wing-teknik — Expert sukaku gives minimal starting eliminations, simulating a classic grid mid-solve — fish are mandatory, and the printed marks at least spare you the bookkeeping.
- Swordfish technique — Tally each digit's column pattern across rows in the printed marks — expert sukaku grids are seeded so that one Swordfish unlocks the cascade that finishes the puzzle.
