如何玩立方体/3D数独
两个9×9数独网格共享一个3×3角落宫。网格A（蓝色）覆盖第1-9行、第1-9列。网格B（绿色）覆盖第7-15行、第7-15列。共享宫（第7-9行、第7-9列）同时满足两个网格。每个网格必须独立满足标准数独规则。

困难 级别的解题技巧
| 技巧 | 描述 | 级别 |
|---|---|---|
| Shared Box Exploitation | The overlapping 3×3 box satisfies both grids. Digits placed here eliminate from rows and columns in both Grid A and Grid B simultaneously. | 初级 |
| Grid A/B Isolation | Outside the shared box, each grid operates independently. Apply standard 9×9 Sudoku logic to each grid in turn. | 中级 |
| Cross-Grid Cascade | Completing the shared box often cascades through the adjacent rows and columns of both grids, rapidly resolving nearby cells. | 中级 |
| Overlap Constraint | The shared box must satisfy: Grid A's bottom-right box rules, AND Grid B's top-left box rules, AND both grids' overlapping row/column constraints. | 高级 |
| Twin Digit Counting | Each digit appears 9 times in Grid A and 9 times in Grid B, but only once in the shared box. This counting helps verify near-complete grids. | 高级 |

在困难需要掌握的技巧
- Hidden Pairs technique — Cross-grid traffic through the overlap silently prunes the boxes adjacent to it — recount those eight boxes (four per grid) regularly; hard cube grids hide pairs exactly there.
- X翼技巧 — Build fish strictly within one grid — rows of grid A and grid B never combine — but prioritise X-Wings whose eliminations touch the shared box, since those feed both grids.
