Cara Bermain Anti-Consecutive Sudoku
Sel yang bersebelahan secara ortogon tidak boleh mengandungi digit berturutan.
Peraturan
Peraturan Sudoku standard terpakai: isi setiap baris, lajur, dan kotak 3×3 dengan digit 1–9, setiap satu muncul tepat sekali.
Anti-Consecutive Sudoku (bentuk yang lebih ketat dari Non-Consecutive Sudoku) mengenakan peraturan bahawa tiada dua sel yang bersebelahan secara ortogon boleh mengandungi integer berturutan. Varian ini sering memerlukan lebih sedikit digit yang diberi kerana kekangan itu sahaja menghapuskan begitu banyak pasangan calon. Ia kadangkala digabungkan dengan Anti-King atau Anti-Knight untuk mencipta teka-teki yang sangat terhad.

Cara Menyelesaikan Anti-Consecutive Sudoku
Soalan Lazim
Apakah 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? ▾
The rule is simple and the early eliminations are satisfying and obvious. Easy puzzles are well-suited for Sudoku players who want a step up from classic without learning arithmetic (like Killer or Arrow). The non-consecutive constraint is entirely logic-based.
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.
