Como jogar Anti-Consecutive Sudoku
As regras padrão do Sudoku se aplicam. Regra extra: duas células ortogonalmente adjacentes (compartilhando uma borda) não podem conter dígitos consecutivos. Se uma célula contém 5, todos os quatro vizinhos devem evitar 4 e 6.

O Que É Sudoku Anticonsecutivo?
O Sudoku Anticonsecutivo (uma forma mais estrita do Sudoku Não Consecutivo) impõe a regra de que duas células ortogonalmente adjacentes não podem conter inteiros consecutivos. Essa variante geralmente requer menos dígitos fornecidos porque a restrição sozinha elimina muitos pares candidatos. Às vezes é combinado com Anti-King ou Anti-Knight para criar quebra-cabeças extremamente restritos.

Como Resolver Sudoku Anticonsecutivo
| Técnica | O Que Ela Faz | Nível |
|---|---|---|
| Global Candidate Pruning | For every filled cell, remove its ±1 neighbours from all orthogonally adjacent cells immediately. | Avançado |
| Digit 5 is Most Constrained | 5 cannot be adjacent to 4 or 6. Use this to restrict placement of 5 across the entire grid. | Avançado |
| Chain Propagation | Placing a digit propagates constraints along rows and columns, often triggering a cascade of forced placements. | Avançado |
| Forbidden Pair Maps | Build a map of forbidden digit pairs for each adjacent pair of cells and use it to eliminate candidates systematically. | Avançado |

Perguntas Frequentes
O que é Anti-Consecutive Sudoku?
Anti-Consecutive Sudoku is a variant where no two orthogonally adjacent cells (horizontally or vertically neighbouring) may contain consecutive digits. The rule applies everywhere on the grid without any markers. Standard Sudoku rules also apply throughout.
How is Anti-Consecutive different from Non-Consecutive Sudoku?
Anti-Consecutive and Non-Consecutive Sudoku are the same constraint — the name is used interchangeably by different puzzle communities. Both mean: no two horizontally or vertically neighbouring cells may hold digits that differ by exactly 1.
Which digit placements trigger the most eliminations?
Digits in the middle of the range (4, 5, 6) eliminate two consecutive neighbours simultaneously. Placing a 5 removes both 4 and 6 from all four orthogonal neighbours, and placing those 4s and 6s in turn removes 3 and 7 from their neighbours — creating a cascade effect. Starting with central digits often unlocks large portions of the grid.
Is Anti-Consecutive Sudoku accessible for beginners?
What is the best approach to Anti-Consecutive Sudoku?
Treat the anti-consecutive constraint as an additional elimination layer. After every digit placement, immediately update all four orthogonal neighbours to remove ±1 from their candidate lists. The more given digits you have to start with, the more these cascade eliminations interact.
How long does Anti-Consecutive Sudoku take to solve?
Easy puzzles take 5–15 minutes. Medium puzzles run 15–30 minutes. Hard puzzles average 30–55 minutes and expert puzzles can take 60–90 minutes. Expert puzzles with very few given digits rely entirely on the anti-consecutive constraint for deductions.
