Løsningsteknikker for Ekspert niveau
| Teknik | Beskrivelse | Niveau |
|---|---|---|
| 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. | Begynder |
| Minimum/Maximum Bounding | The bulb value is ≤ 9 − (N − 1). The tip value is ≥ N. Apply these bounds immediately to prune all thermometer candidates. | Begynder |
| Overlapping Thermometer Deduction | Two thermometers sharing a cell give tighter combined bounds than either alone. | Mellemniveau |
| 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. | Avanceret |
| Short vs. Long Thermometers | A 2-cell thermometer is simply a greater-than relationship. A 9-cell thermometer forces exactly 1–9 in order. | Mellemniveau |
Teknikker at mestre på Ekspert
- X-Wing-teknik — Expert thermo endgames run on the extremes: thermometers force 8s and 9s away from tips of short lines, leaving textbook two-per-row X-Wing geometry.
- Swordfish technique — When several long thermometers parallel each other, mid-range digits get confined to the same three columns across three rows — exactly the Swordfish setup expert grids exploit.

Pil Sudoku
Thermo and Arrow both constrain digits along drawn lines — increase swaps for summation, but the cell-by-cell bounding feels the same.
Tyske hvisken
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.
