Løsningsteknikker for Ekspert-nivå
| Teknikk | Beskrivelse | Nivå |
|---|---|---|
| High-Low Alternation | Adjacent cells on the line must differ by ≥ 5. This forces a strict alternating high-low pattern: low (1–4) alternates with high (6–9). | Nybegynner |
| Digit 5 Exclusion | 5 cannot appear on any German Whispers line — no digit within 1–9 differs from 5 by at least 5. Eliminate 5 from all line cells immediately. | Nybegynner |
| Low-Set {1,2,3,4} / High-Set {6,7,8,9} | Every whisper cell belongs to one of these two sets. Apply row/column/box constraints within each set to narrow candidates. | Middels |
| Endpoint Parity | The parity (high or low) of the line is not fixed — it's determined by surrounding constraints. Resolving one endpoint propagates the alternation inward. | Avansert |
Teknikker å mestre på Ekspert
- X-Wing-teknikk — Expert whisper grids thread lines through nearly every box; once alternation is mapped, fish on 4 and 6 — the digits with the single whisper partner (9 and 1 respectively).
- Swordfish technique — Long lines push lows and highs into repeating column patterns across rows; a Swordfish on a low digit across three line-heavy rows typically breaks the expert endgame.
