저먼 위스퍼스 스도쿠 플레이 방법
표준 스도쿠 규칙이 적용됩니다. 녹색 선을 따라 인접한 두 셀은 최소 5 이상 차이가 나야 합니다. 이는 큰 값(6–9)과 작은 값(1–4)이 번갈아 나타나도록 합니다.

녹색 선 위의 인접한 숫자는 적어도 5만큼 차이가 나야 합니다.
저먼 위스퍼스이란 무엇인가요?
German Whispers (Whisper Sudoku라고도 함)는 그리드에 녹색 선을 그립니다. 선에서 인접한 두 숫자는 최소 5만큼 달라야 합니다. 최소 차이가 5이고 숫자 범위가 1–9이므로, 이는 강한 고-저 교대 패턴을 만듭니다: 한 셀이 낮으면(1–4), 다음은 높아야 하며(6–9) 그 반대도 마찬가지입니다. 선 제약은 대부분의 위치에서 5를 유효한 숫자로 제거합니다.

저먼 위스퍼스 푸는 방법
| 기법 | 기능 | 레벨 |
|---|---|---|
| High-Low Alternation | Adjacent cells on the line must differ by ≥ 5. This forces a strict alternating high-low pattern: low (1–4) alternates with high (6–9). | 고급 |
| Digit 5 Exclusion | 5 cannot appear on any German Whispers line — no digit within 1–9 differs from 5 by at least 5. Eliminate 5 from all line cells immediately. | 고급 |
| Low-Set {1,2,3,4} / High-Set {6,7,8,9} | Every whisper cell belongs to one of these two sets. Apply row/column/box constraints within each set to narrow candidates. | 고급 |
| Endpoint Parity | The parity (high or low) of the line is not fixed — it's determined by surrounding constraints. Resolving one endpoint propagates the alternation inward. | 고급 |

자주 묻는 질문
German Whispers Sudoku란 무엇인가요?
German Whispers Sudoku is a variant where green lines are drawn across the grid. Any two cells adjacent along a green line must contain digits that differ by at least 5. Standard Sudoku rules apply — every row, column, and 3×3 box must contain 1–9 exactly once.
Why is it called German Whispers?
The name comes from the puzzle community and refers to a variant popularised in German puzzle circles, with 'whispers' evoking the idea of information passing along a line with a significant minimum separation at each step.
What digits can sit next to each other on a whisper line?
Only pairs with a difference of 5 or more: 1&6, 1&7, 1&8, 1&9, 2&7, 2&8, 2&9, 3&8, 3&9, 4&9. This means whisper cells must alternate between the low group (1–4) and high group (6–9). Digit 5 cannot appear on any whisper line.
What is the best first move in German Whispers Sudoku?
Identify the longest whisper lines and mark each cell as low (1–4) or high (6–9) based on alternation. Any whisper cell in a row, column, or box where the low or high group is almost fully placed gives you a direct elimination or placement.
Is German Whispers Sudoku hard to learn?
The constraint is simple to understand but its consequences take practice to apply automatically. The forced high-low alternation is the key insight — once you internalise it, you can immediately split each line cell into one of two groups and halve your candidate list from the start.
How long does German Whispers Sudoku take to solve?
Easy puzzles take 8–18 minutes. Medium puzzles run 18–35 minutes. Hard and expert puzzles can take 45 minutes to well over an hour. Longer whisper lines spanning the full grid are the most time-consuming because they interact with almost every row, column, and box simultaneously.
