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：專家 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 專家 需要掌握的技巧
- X-Wing 技巧 — Expert cube puzzles deadlock each grid separately and hide the key in the overlap — an X-Wing in one grid that clears a shared-box candidate is usually the turn of the lock.
- Swordfish technique — Run Swordfish scans per grid in alternation; expert cube endgames typically need one fish per grid, sequenced so the first one's overlap eliminations enable the second.
