解謎技巧（困難 等級）
| 技巧 | 描述 | 等級 |
|---|---|---|
| Border Reading | Thick borders separate cells in different regions. Cells without thick borders between them are in the same region. Map connected groups first. | 初學者 |
| Region Size Counting | Each region contains exactly 9 cells. Count connected groups to verify region membership and identify boundaries. | 中級 |
| Deducing Regions from Digits | If standard row/column logic places a digit, use that placement to confirm or deny region membership — a region can only contain each digit once. | 中級 |
| Region Pointer Pairs | If a digit in a deduced region is confined to one row or column, eliminate it from that entire row or column. | 進階 |
| Construction and Solving Together | Alternate between deducing region structure and placing digits — each informs the other in a co-dependent process. | 進階 |

在 困難 需要掌握的技巧
- Hidden Pairs technique — Apply pair logic to confirmed region fragments: two digits confined to two cells of a 6-cell fragment already eliminate from the fragment, even before its last three cells are mapped.
- X翼技巧 — Row-and-column fish are region-independent, making X-Wing the most reliable tool while borders are still unknown — its eliminations are immune to your region mistakes.
