كيفية لعب جيرمن ويسبيرز سودوكو
تطبق قواعد السودوكو القياسية. يجب أن تختلف أي خليتين متجاورتين على طول خط أخضر بمقدار 5 على الأقل. هذا يفرض التناوب بين القيم الكبيرة (6–9) والصغيرة (1–4).

ما هو جيرمن ويسبيرز؟
German Whispers (المعروف أيضًا باسم Whisper Sudoku) يرسم خطوطًا خضراء على الشبكة. أي رقمين متجاورين على الخط يجب أن يختلفا بمقدار 5 على الأقل. نظرًا لأن الحد الأدنى للفرق هو 5 والأرقام تتراوح من 1–9، فإن هذا يخلق نمطًا قويًا متناوبًا بين المرتفع والمنخفض: إذا كانت إحدى الخلايا منخفضة (1–4)، فيجب أن تكون التالية مرتفعة (6–9) والعكس صحيح. قيد الخط يلغي 5 كرقم صالح في معظم المواضع.

كيفية حل جيرمن ويسبيرز
| تقنية | ما يفعله | المستوى |
|---|---|---|
| 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). | متقدم |
| 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. | متقدم |
| 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. | متقدم |
| 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. | متقدم |

أسئلة شائعة
شو هو German Whispers Sudoku؟
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.
