Comment jouer à Sukaku
Une variante de style pencilmark où les indices sont donnés comme ensembles de candidats
Les règles
Les règles standard du Sudoku s'appliquent : remplissez chaque ligne, colonne et bloc 3×3 avec les chiffres 1–9, chacun apparaissant exactement une fois.
Sukaku (数角) est une variante du Sudoku où, au lieu de chiffres donnés, chaque cellule reçoit un ensemble de candidats possibles. Le solveur doit éliminer les candidats en utilisant la logique standard du Sudoku jusqu'à ce que chaque cellule ait exactement un candidat restant. Certains puzzles Sukaku fournissent des ensembles de candidats très clairsemés (quasi-complets), tandis que d'autres fournissent des listes de candidats complètes ou presque complètes, nécessitant des techniques avancées pour être résolus.

Questions courantes
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.
En quoi Sukaku est-il différent du Sudoku régulier ? ▾
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.
