كيفية لعب سوكاكو
تبدأ كل خلية بمجموعة من الأرقام المرشحة المعروضة كعلامات قلم رصاص. اضغط على رقم لحذف هذا المرشح من الخلية المحددة. عندما يبقى مرشح واحد فقط، يتم وضع الرقم تلقائيًا. الخلايا التي تظهر رقمًا كبيرًا واحدًا ثابتة ولا يمكن تعديلها. تنطبق قواعد السودوكو القياسية للصف والعمود والمربع.

ما هو سوكاكو؟
Sukaku (数角) هو نوع من Sudoku حيث بدلاً من given digits, كل خلية تُعطى مجموعة من candidates. يجب على solver حذف candidates باستخدام standard Sudoku logic حتى تحتوي كل خلية على candidate واحد متبقي بالضبط. بعض Sukaku puzzles توفر مجموعات candidates قليلة جدًا (near-complete givens), بينما توفر أخرى قوائم candidates كاملة أو شبه كاملة, مما يتطلب advanced techniques لحلها.

كيفية حل سوكاكو
| تقنية | ما يفعله | المستوى |
|---|---|---|
| Candidate Scanning | Start by scanning rows, columns, and boxes — any candidate appearing in only one cell in a group must be placed there. | متقدم |
| Cross-Hatch Elimination | When a digit is placed (or reduced to one candidate), eliminate it from all cells in the same row, column, and box. | متقدم |
| فرادى عارية | A cell with only one remaining candidate is a naked single — the digit is forced. In Sukaku, this happens automatically when you eliminate down to one candidate. | متقدم |
| فرديات مخفية | A candidate that appears exactly once in a row, column, or box must be placed in that cell regardless of how many other candidates that cell shows. | متقدم |
| Pair Elimination | Two cells in a group that share only the same two candidates form a naked pair — both candidates can be eliminated from all other cells in that group. | متقدم |

أسئلة شائعة
What is Sukaku?
Sukaku is a Sudoku variant where every cell in the 9×9 grid starts pre-filled with a set of pencilmark candidates instead of given digits. Your task is to eliminate incorrect candidates using standard Sudoku rules until exactly one digit remains in each cell. All 81 cells begin with multiple possibilities.
كيف يختلف سوكاكو عن سودوكو العادي؟
In classic Sudoku, some cells are pre-filled with confirmed digits. In Sukaku, no cell has a confirmed digit — instead, each cell shows a subset of possible digits as pencilmarks. The starting pencilmarks are curated by the puzzle constructor and are always consistent with the unique solution.
Are the starting pencilmarks always correct?
Yes. The pencilmarks shown at the start of a Sukaku puzzle represent a valid subset of candidates for each cell — they are never wrong, but they may include more candidates than strictly necessary. Your job is to eliminate all but the correct digit using logical deductions.
What techniques work best in Sukaku?
All standard Sudoku elimination techniques apply: naked singles (when only one candidate remains in a cell), hidden singles (when a digit can only go in one cell within a row, column, or box), naked pairs, pointing pairs, and advanced techniques like X-Wings and Swordfish. The absence of given digits means you rely entirely on elimination.
Is Sukaku harder than regular Sudoku?
Easy Sukaku is more forgiving than classic Sudoku because the pencilmarks are already provided — you never have to work out candidates from scratch. Hard and expert Sukaku puzzles with minimal starting candidates require the same advanced techniques as difficult classic Sudoku.
How long does Sukaku take to solve?
Easy puzzles take 5–15 minutes. Medium puzzles run 15–30 minutes. Hard puzzles average 30–60 minutes and expert puzzles can take over 90 minutes. Solve time scales with how many eliminations each technique step provides.
