Lösningstekniker för Expert nivå
| Teknik | Beskrivning | Nivå |
|---|---|---|
| Diagonal Exclusion | The king constraint extends the exclusion zone to all 8 neighbours including diagonals. Apply diagonal exclusions before standard row/col/box logic. | Nybörjare |
| Corner Restriction | Corner cells (e.g., r1c1) only have 3 king-move neighbours. Start with corners and edges to build initial placements. | Medel |
| King-Chain Elimination | When a digit is placed, eliminate it simultaneously from all 8 surrounding cells. | Medel |
| Parity via King's Move | In Anti-King, consecutive digits often become mutually king-move incompatible — trace valid placement paths using this property. | Avancerad |
Tekniker att bemästra vid Expert
- X-Wing-teknik — At expert level, combine the fish with king logic: an X-Wing corner placement also clears the digit from eight surrounding cells, often collapsing a whole region.
- Swordfish technique — Expert Anti-King puzzles thin candidates with diagonal pressure until three-row Swordfish patterns become the only path — look for them on digits clustered near the grid centre.
