Cómo jugar a Sukaku
Una variante de estilo de marcas de lápiz donde las pistas se dan como conjuntos de candidatos
Las reglas
Se aplican las reglas estándar del Sudoku: rellena cada fila, columna y caja de 3×3 con los dígitos del 1 al 9, cada uno apareciendo exactamente una vez.
Sukaku (数角) es una variante de Sudoku donde, en lugar de dígitos dados, cada celda recibe un conjunto de candidatos posibles. El solucionador debe eliminar candidatos usando la lógica estándar del Sudoku hasta que cada celda tenga exactamente un candidato restante. Algunos rompecabezas de Sukaku proporcionan conjuntos de candidatos muy escasos (casi completos), mientras que otros proporcionan listas de candidatos completas o casi completas, requiriendo técnicas avanzadas para resolver.

Preguntas Comunes
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 qué se diferencia Sukaku del Sudoku regular? ▾
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.
