Anti-Consecutive Sudoku (a stricter form of Non-Consecutive Sudoku) imposes the rule that no two orthogonally adjacent cells may contain consecutive integers. This variant often requires fewer given digits because the constraint alone eliminates so many candidate pairs. It is sometimes combined with Anti-King or Anti-Knight to create extremely constrained puzzles.

Frequently Asked Questions

Which cells count as adjacent?
Only orthogonally adjacent cells — sharing an edge horizontally or vertically. Diagonal neighbours are unaffected.
Is Anti-Consecutive different from Non-Consecutive?
They use the same constraint — no two orthogonally adjacent cells may contain consecutive digits. Anti-Consecutive is another name for the same variant.
