专家 级别的解题技巧
| 技巧 | 描述 | 级别 |
|---|---|---|
| Length-Based Range | A Renban line of length L must contain L consecutive integers. The starting value is between 1 and 10−L, giving 10−L possible ranges. | 初级 |
| Shared Cell Intersection | If two Renban lines share a cell, that cell's value must fit both lines' consecutive ranges. Intersect the ranges to find valid values. | 中级 |
| Single-Range Reduction | When a Renban line's valid range reduces to a single starting value, all cell values are fully determined (in some order). | 中级 |
| Renban–Box Interaction | Digits on a Renban line within one box restrict the box's remaining cells. Use box uniqueness to narrow the line's range. | 高级 |
在专家需要掌握的技巧
- X翼技巧 — Expert renban grids overlap long lines so runs stay ambiguous — fish on the digits no candidate run can reach, then feed each elimination back into the run lists.
- Swordfish technique — Parallel renban lines push the same excluded digits into matching off-line columns, three rows at a time — expert endgames here are textbook Swordfish territory.

德国耳语
The mirror image of renban logic: lines that forbid close digits instead of requiring a consecutive run.
回文数独
Another line whose meaning is about the set of digits on it — here the line must read the same in both directions.
线间数独
Swaps the consecutive-run rule for a bounded-range rule anchored by two endpoint circles — kindred range reasoning.
