Cara bermain Anti-Consecutive Sudoku
Aturan standar Sudoku berlaku. Aturan tambahan: tidak ada dua sel yang berdekatan secara ortogonal (berbagi tepi) yang boleh berisi digit berurutan. Jika sebuah sel berisi 5, keempat tetangganya harus menghindari 4 dan 6.

Apa itu Anti-Consecutive Sudoku?
Sudoku Anti-Berurutan (bentuk yang lebih ketat dari Non-Consecutive Sudoku) memberlakukan aturan bahwa tidak ada dua sel yang berdekatan secara ortogonal yang boleh berisi bilangan bulat berurutan. Varian ini seringkali membutuhkan lebih sedikit digit yang diberikan karena batasan itu sendiri menghilangkan begitu banyak pasangan kandidat. Kadang-kadang dikombinasikan dengan Anti-Raja atau Anti-Ksatria untuk menciptakan teka-teki yang sangat terbatas.

Cara Memecahkan Anti-Consecutive Sudoku
| Teknik | Apa yang dilakukannya | Level |
|---|---|---|
| Global Candidate Pruning | For every filled cell, remove its ±1 neighbours from all orthogonally adjacent cells immediately. | Lanjutan |
| Digit 5 is Most Constrained | 5 cannot be adjacent to 4 or 6. Use this to restrict placement of 5 across the entire grid. | Lanjutan |
| Chain Propagation | Placing a digit propagates constraints along rows and columns, often triggering a cascade of forced placements. | Lanjutan |
| Forbidden Pair Maps | Build a map of forbidden digit pairs for each adjacent pair of cells and use it to eliminate candidates systematically. | Lanjutan |

Pertanyaan yang Sering Diajukan
Apa itu 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.
