Como jogar Clone Sudoku
As regras padrão do Sudoku se aplicam. Duas regiões destacadas (Clone A em âmbar, Clone B em roxo) devem conter arranjos de dígitos idênticos — células correspondentes devem conter o mesmo dígito. Colocar um dígito em um clone automaticamente restringe a mesma posição no outro clone.

O Que É Sudoku Clone?
Clone Sudoku marca pares de regiões (clones) na grade. Cada par de regiões clone deve conter exatamente o mesmo arranjo de dígitos — se um clone tem um 3 em sua célula superior esquerda, o outro clone também deve ter um 3 em sua célula correspondente. As restrições de clone criam deduções poderosas baseadas em simetria que podem resolver regiões inteiras de uma vez.

Como Resolver Sudoku Clone
| Técnica | O Que Ela Faz | Nível |
|---|---|---|
| Clone Pair Deduction | Any digit placed in one clone region immediately forces the same digit in the corresponding cell of the other clone region. | Avançado |
| Constraint Propagation | A clone placement propagates through standard row, column, and box constraints in both regions simultaneously. | Avançado |
| Clone-Box Interaction | If both clone regions share boxes with heavily constrained cells, the clone constraint rapidly resolves entire boxes. | Avançado |
| Mirror Elimination | When a digit is eliminated from a position in one clone region by standard logic, it can be eliminated from the same position in the other clone region. | Avançado |
| Multi-Clone Logic | With two clone regions, solving either provides equal information about both. Alternate deduction paths between clones for maximum efficiency. | Avançado |

Perguntas Frequentes
O que é 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.
