专家 级别的解题技巧
| 技巧 | 描述 | 级别 |
|---|---|---|
| Diagonal Exclusion | The king constraint extends the exclusion zone to all 8 neighbours including diagonals. Apply diagonal exclusions before standard row/col/box logic. | 初级 |
| Corner Restriction | Corner cells (e.g., r1c1) only have 3 king-move neighbours. Start with corners and edges to build initial placements. | 中级 |
| King-Chain Elimination | When a digit is placed, eliminate it simultaneously from all 8 surrounding cells. | 中级 |
| Parity via King's Move | In Anti-King, consecutive digits often become mutually king-move incompatible — trace valid placement paths using this property. | 高级 |
在专家需要掌握的技巧
- X翼技巧 — 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.
