사무라이 스도쿠 플레이 방법
다섯 개의 겹치는 9×9 스도쿠 그리드. 각 하위 그리드는 독립적으로 표준 스도쿠 규칙(각 행, 열, 박스에 1-9)을 충족해야 합니다. 두 하위 그리드가 3×3 코너 박스를 공유하는 경우, 해당 박스는 두 그리드를 동시에 충족해야 합니다.

사무라이 스도쿠이란 무엇인가요?
Samurai Sudoku는 X자 모양으로 배열된 5개의 맞물린 9×9 grids로 구성됩니다 — 하나의 central grid와 네 개의 corner grids, 모두 겹치는 3×3 box를 공유합니다. 5개의 sub-grids 각각은 독립적으로 standard Sudoku rules를 만족해야 합니다. 하나의 sub-grid를 푸는 것은 종종 다른 sub-grid를 여는 clues를 제공합니다. 전체 퍼즐은 21×21 grid에 걸쳐 있습니다.

사무라이 스도쿠 푸는 방법
| 기법 | 기능 | 레벨 |
|---|---|---|
| Sub-Grid Independence | Each of the five 9×9 sub-grids satisfies standard Sudoku rules independently. Solve each one using all standard techniques. | 고급 |
| Overlap Box Exploitation | The four corner boxes where sub-grids meet are shared between two grids. Any digit placed in a shared box eliminates that digit from two sub-grids at once. | 고급 |
| Cross-Grid Cascade | Completing a corner box in the central grid forces values in the corresponding corner grid's box, which may cascade further through that grid. | 고급 |
| Shared Box Forcing | When a shared box is nearly complete, use both sub-grids' row and column constraints to force the remaining digits. | 고급 |
| Global Number Counting | Across all five sub-grids, each digit 1–9 appears 5×9=45 times total. This global count can confirm placement decisions near the end. | 고급 |

자주 묻는 질문
Samurai Sudoku란 무엇인가요?
Samurai Sudoku is a variant consisting of five overlapping 9×9 Sudoku grids arranged on a 21×21 board. One grid occupies the centre, and four grids are placed at the corners with their inner 3×3 boxes overlapping the centre grid's corner boxes. All five grids must be solved simultaneously.
How do the overlapping boxes work?
Each of the four outer grids shares one 3×3 box with the centre grid. Any digit placed in a shared box satisfies the constraint for both grids simultaneously. This means information flows between grids through the shared boxes — solving one grid's corner often directly advances the centre grid.
Do all five grids have standard Sudoku rules?
Yes. Each of the five 9×9 grids individually follows all standard Sudoku rules: every row, column, and 3×3 box within that grid must contain 1–9 exactly once. The only interaction between grids is through the shared corner boxes.
Is Samurai Sudoku harder than regular Sudoku?
Samurai puzzles take significantly longer than single-grid Sudoku simply due to scale — you're solving five grids. Individual difficulty can range from easy to expert. The cross-grid interactions through shared boxes add a satisfying extra layer that single-grid Sudoku doesn't offer.
What is the best approach to Samurai Sudoku?
Work on all five grids simultaneously rather than trying to complete one before moving to another. When you get stuck on one grid, the shared boxes often provide a breakthrough from a neighbouring grid. Scan all five grids for hidden singles after every placement in any shared box.
How long does Samurai Sudoku take to solve?
Easy puzzles take 25–45 minutes. Medium puzzles run 45–90 minutes. Hard and expert puzzles can take 2–4 hours. The time is primarily driven by scale — five full grids — rather than by individual deduction difficulty.
