كيفية لعب جيغسو سودوكو
تطبق قواعد الصف والعمود القياسية. كل منطقة ملونة (محددة بحد سميك) يجب أن تحتوي أيضًا على 1–9 مرة واحدة بالضبط. المناطق تحل محل الصناديق القياسية 3×3.

ما هو سودوكو الأحجية؟
جيجسو سودوكو (يسمى أيضًا سودوكو غير المنتظم) يستبدل المربعات القياسية التسعة 3×3 بتسع مناطق غير منتظمة على شكل قطع الصور المقطوعة. كل منطقة لا تزال تحتوي على تسع خلايا ويجب أن تحتوي على كل رقم من 1 إلى 9 مرة واحدة بالضبط. قواعد الصفوف والأعمدة تبقى دون تغيير. الأشكال غير المنتظمة يمكن أن تخلق مسارات حل مختلفة جدًا عن سودوكو الكلاسيكي.

كيفية حل سودوكو الأحجية
| تقنية | ما يفعله | المستوى |
|---|---|---|
| Region Identification First | Identify all 9 irregular regions by their colour coding before solving. Region membership determines the third constraint unit for each cell. | متقدم |
| Region Counting | Each region must contain 1–9. Counting completed rows and columns reveals how many of each digit can still fit in each region. | متقدم |
| Region–Row/Column Intersection | If a digit within a region is confined to one row or column, eliminate it from the rest of that row or column. | متقدم |
| Irregular Naked Subsets | Apply naked pairs and triples within each irregular region exactly as you would within standard 3×3 boxes. | متقدم |

أسئلة شائعة
شو هو Irregular Sudoku؟
Irregular Sudoku (also called Jigsaw Sudoku) replaces the standard nine 3×3 boxes with nine irregularly-shaped regions of exactly nine cells each. Every row, column, and irregular region must still contain the digits 1–9 exactly once. The regions are colour-coded or outlined with thick borders.
How do I identify the irregular regions?
Each region is shaded in a distinct colour or enclosed by thicker lines. Count the cells in each region to confirm it has exactly nine. The regions are always connected — no region is split across the grid — but they can have any shape as long as they tile the full 9×9 grid.
Is solving Irregular Sudoku different from classic Sudoku?
The logic is identical — you use the same techniques (naked pairs, hidden singles, pointing pairs, etc.) — but the non-rectangular region shapes create different constraint interactions. A region that snakes diagonally creates eliminations in many different rows and columns simultaneously, which can feel unintuitive at first.
Is Irregular Sudoku harder than regular Sudoku?
At easy difficulty, Irregular Sudoku can be harder because the region shapes are less predictable than 3×3 boxes. At higher difficulties, experienced Sudoku players often find it comparably challenging — the same techniques apply, just with different geometry.
What is the best strategy for Irregular Sudoku?
Trace each region carefully before starting — understand its shape and which rows and columns it spans. Regions that span many different rows and columns create more powerful constraints. Focus on regions with the most given digits first, then use pointing pairs to transfer information between regions and lines.
How long does Irregular Sudoku take to solve?
Easy puzzles take 8–20 minutes. Medium puzzles run 20–40 minutes. Hard and expert puzzles can take 45–90 minutes. Familiarity with jigsaw region shapes speeds up solving considerably after a few practice puzzles.
