Cómo jugar a Sudoku Clon
Las regiones marcadas deben contener disposiciones de dígitos idénticas
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.
El Sudoku Clone marca pares de regiones (clones) en la cuadrícula. Cada par de regiones clon debe contener exactamente la misma disposición de dígitos: si un clon tiene un 3 en su celda superior izquierda, el otro clon también debe tener un 3 en su celda correspondiente. Las restricciones de clon crean poderosas deducciones basadas en simetría que pueden resolver regiones enteras de una vez.

Preguntas Comunes
¿Qué es Clone Sudoku? ▾
Clone Sudoku is a variant where two highlighted regions of the same shape appear on the grid. The two regions are 'clones' — they must contain exactly the same digit arrangement. Every cell in one region holds the same digit as the corresponding cell in the other region. Standard Sudoku rules apply.
How do the clone regions correspond? ▾
The two clone regions are the same shape and size. Each cell in one region is paired with the corresponding positionally-equivalent cell in the other region. Placing a digit in any cell of one clone immediately fixes that digit in the matching cell of the other clone.
Can clone regions overlap with the same rows or columns? ▾
Yes. The puzzle constructor ensures that the clone constraint is always consistent with Sudoku rules — the two regions are positioned so that corresponding cells are in different rows, columns, and boxes, allowing the same digit to appear in both without violating uniqueness.
Is Clone Sudoku harder than regular Sudoku? ▾
The clone constraint effectively halves the number of independent cells to solve — every deduction in one region automatically applies to the other. Easy Clone puzzles resolve noticeably faster than classic Sudoku. Hard and expert puzzles use the clones to create complex bi-directional constraint chains.
What is the best strategy for Clone Sudoku? ▾
Treat the two clone regions as a single constraint. Whenever you eliminate a candidate from a cell in one region, immediately eliminate it from the corresponding cell in the other. Focus on the rows, columns, and boxes that interact with both regions simultaneously.
How long does Clone Sudoku take to solve? ▾
Easy puzzles take 6–15 minutes. Medium puzzles run 15–30 minutes. Hard puzzles average 30–60 minutes and expert puzzles can take 60–90 minutes. The bilateral nature of the clone constraint makes mid-game breakthroughs especially satisfying.
