Vanskelig Thermo Sudoku
Sifre må øke fra pæreenden til spissen langs hvert termometer. Temperaturretning begrenser hver plassering.
Vanskelig Termo Sudoku. Færre gitte, overlappende termoer — forvent flertrinns grensededuksjoner og omfattende blyantnotat arbeid.

Løsningsteknikker for Vanskelig-nivå
| Teknikk | Beskrivelse | Nivå |
|---|---|---|
| Range Restriction from Length | A thermometer with N cells must use N strictly increasing distinct values. The bulb is at least 1 and the tip is at most 9, giving a calculable valid range for each cell. | Nybegynner |
| Minimum/Maximum Bounding | The bulb value is ≤ 9 − (N − 1). The tip value is ≥ N. Apply these bounds immediately to prune all thermometer candidates. | Nybegynner |
| Overlapping Thermometer Deduction | Two thermometers sharing a cell give tighter combined bounds than either alone. | Middels |
| Forcing Chains via Thermometers | When a value is forced into a thermometer cell, all cells closer to the bulb must be smaller and all closer to the tip must be larger. | Avansert |
| Short vs. Long Thermometers | A 2-cell thermometer is simply a greater-than relationship. A 9-cell thermometer forces exactly 1–9 in order. | Middels |

Teknikker å mestre på Vanskelig
- Hidden Pairs technique — Overlapping thermometers compress candidate windows until two digits share only two line cells; hard thermo grids hide their pairs along the slow middle of long lines.
- X-Wing-teknikk — Bulb and tip bounds eliminate so many extreme-digit candidates that X-Wings on 1, 2, 8, and 9 appear early — hunt fish on the digits the thermometers exclude.

Pil Sudoku
Thermo and Arrow both constrain digits along drawn lines — increase swaps for summation, but the cell-by-cell bounding feels the same.
German Whispers
Another drawn-line rule: instead of strictly increasing, neighbouring line digits must differ by at least 5.
Renban Sudoku
Line cells must form a consecutive set rather than an increasing one — the same range-tracking instinct, loosened by one degree.
