큐브 / 3D 스도쿠 플레이 방법
정육면체 또는 기타 3D 레이아웃의 면에 배열된 Sudoku
규칙
표준 스도쿠 규칙이 적용됩니다: 모든 행, 열, 3×3 박스에 숫자 1–9를 각각 정확히 한 번씩 채웁니다.
3D Sudoku 변형은 Sudoku 그리드를 3차원 구성으로 배열합니다 — 일반적으로 큐브의 여섯 면에, 인접한 면이 가장자리 행이나 열을 공유합니다. 해결책은 각 면에서 독립적으로 Sudoku 규칙을 만족해야 하며, 동시에 공유된 가장자리를 따라 제약 조건도 만족해야 합니다. 이는 독특한 cross-face logic을 가진 멋진 시각적 퍼즐 형식을 만듭니다.

자주 묻는 질문
Cube Sudoku (3D Sudoku)란 무엇인가요? ▾
Cube Sudoku (also called 3D Sudoku or Tridoku) consists of two 9×9 Sudoku grids that share a common 3×3 box at their overlapping corner. Both grids must independently satisfy all standard Sudoku rules, and the shared corner box must simultaneously satisfy both grids' box constraint.
How does the shared box work? ▾
The shared corner box is part of both grids. Any digit placed in that box counts toward the uniqueness constraint for both grids simultaneously. This means solving either grid's corner directly constrains the other grid's corner — the two grids communicate only through this shared zone.
Do both grids use the same digits? ▾
Yes. Both grids use the digits 1–9, and both follow standard Sudoku rules independently. The shared box makes the two grids interdependent. A digit placed in the shared box cannot repeat in any row, column, or box of either grid.
Is Cube Sudoku harder than regular Sudoku? ▾
It is roughly twice as much work as a single Sudoku, plus the added challenge of managing the shared corner. Easy Cube puzzles are accessible for experienced Sudoku players. Hard and expert puzzles require actively exploiting the cross-grid constraint, which adds genuine complexity beyond simply solving two independent grids.
What is the best strategy for Cube Sudoku? ▾
Alternate between the two grids rather than solving one completely before the other. Whenever you make progress in the shared corner box, immediately check what that means for the other grid. The shared box is the key to unlocking both grids — maximise information flow through it.
How long does Cube Sudoku take to solve? ▾
Easy puzzles take 15–30 minutes. Medium puzzles run 30–50 minutes. Hard and expert puzzles can take 60–120 minutes. The scale (two full grids) is the primary driver of solve time.
