如何遊玩立方體/3D數獨
兩個 9×9 數獨網格在一個共享的 3×3 角落方塊重疊。網格 A(藍色色調)涵蓋第 1–9 行、第 1–9 列。網格 B(綠色色調)涵蓋第 7–15 行、第 7–15 列。共享方塊(第 7–9 行、第 7–9 列)滿足兩個網格。每個網格必須獨立滿足標準數獨規則。

解題技巧:困難 等級
| 技巧 | 描述 | 等級 |
|---|---|---|
| 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. | 初學者 |
| Grid A/B Isolation | Outside the shared box, each grid operates independently. Apply standard 9×9 Sudoku logic to each grid in turn. | 中級 |
| Cross-Grid Cascade | Completing the shared box often cascades through the adjacent rows and columns of both grids, rapidly resolving nearby cells. | 中級 |
| 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. | 進階 |
| 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. | 進階 |

在 困難 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-Wing 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.
