困难 级别的解题技巧
| 技巧 | 描述 | 级别 |
|---|---|---|
| Clone Pair Deduction | Any digit placed in one clone region immediately forces the same digit in the corresponding cell of the other clone region. | 初级 |
| Constraint Propagation | A clone placement propagates through standard row, column, and box constraints in both regions simultaneously. | 中级 |
| Clone-Box Interaction | If both clone regions share boxes with heavily constrained cells, the clone constraint rapidly resolves entire boxes. | 中级 |
| Mirror Elimination | When a digit is eliminated from a position in one clone region by standard logic, it can be eliminated from the same position in the other clone region. | 高级 |
| Multi-Clone Logic | With two clone regions, solving either provides equal information about both. Alternate deduction paths between clones for maximum efficiency. | 高级 |

在困难需要掌握的技巧
- Hidden Pairs technique — Twin-imported eliminations thin cells invisibly — recount the boxes hosting each clone region after every mirror update, because that's where hard clone grids hide pairs.
- X翼技巧 — Eliminations exported through the clone link land in rows the original logic never touched — re-scan for X-Wings after each mirror transfer, not just after direct placements.

混沌构造
Structure-as-puzzle taken to the limit: instead of mirroring known regions, you deduce where the regions even are.
锯齿数独
Region-shape reading without the mirroring — nine snaking regions replace the standard boxes.
对角线数独
Like clone cells, diagonal cells link distant parts of the grid — placements echo far beyond their own box.
