Løsningsteknikker for Svær 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 Svær
- Hidden Pairs technique — Hard sukaku starts with deliberately bloated candidate lists — hidden pairs are the tool that cuts through, stripping the excess from exactly two cells per unit.
- X-Wing-teknik — Because every candidate is visible, X-Wing rectangles can be spotted by pure pattern-reading — scan each digit's printed positions row by row for the two-and-two shape.
