Svær Anti-King Sudoku
Ingen to identiske tal må røre diagonalt (som en skakkonges træk). Hver celle har op til 8 begrænsede naboer.
Svær Anti-Konge Sudoku. Lange elimineringskæder væver gennem diagonale og standard begrænsninger — blyantsnotater og systematisk initialisering er afgørende.

Løsningsteknikker for Svær niveau
| Teknik | Beskrivelse | Niveau |
|---|---|---|
| Diagonal Exclusion | The king constraint extends the exclusion zone to all 8 neighbours including diagonals. Apply diagonal exclusions before standard row/col/box logic. | Begynder |
| Corner Restriction | Corner cells (e.g., r1c1) only have 3 king-move neighbours. Start with corners and edges to build initial placements. | Mellemniveau |
| King-Chain Elimination | When a digit is placed, eliminate it simultaneously from all 8 surrounding cells. | Mellemniveau |
| Parity via King's Move | In Anti-King, consecutive digits often become mutually king-move incompatible — trace valid placement paths using this property. | Avanceret |

Teknikker at mestre på Svær
- Hidden Pairs technique — King-move eliminations quietly remove candidates that would otherwise hide a pair — recount each box after diagonal eliminations and pairs surface where none seemed possible.
- X-Wing-teknik — Hard Anti-King grids use diagonal adjacency to break would-be X-Wing cells; verify each corner of your rectangle isn't a king's move from the same digit before eliminating.
