Cara Bermain Non-Consecutive Sudoku
Tiada dua sel bersebelahan secara ortogon 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.
Non-Consecutive Sudoku mengenakan kekangan global: tiada dua sel yang berkongsi tepi (bersebelahan secara ortogon) boleh mengandungi digit berturutan. Jadi jika sel mengandungi 5, semua jirannya mesti mengelakkan 4 dan 6. Peraturan tunggal ini sangat mengehadkan penempatan calon dan boleh mengurangkan kiraan berian standard sambil masih menghasilkan teka-teki yang boleh diselesaikan secara unik.

Soalan Lazim
Apakah Non-Consecutive Sudoku? ▾
Non-Consecutive Sudoku is a variant where no two horizontally or vertically adjacent cells may contain consecutive digits. There are no markers on the grid — the non-consecutive rule applies globally to every pair of neighbours. Standard Sudoku rules also apply.
How does the global non-consecutive rule constrain the grid? ▾
Every pair of adjacent cells cannot differ by exactly 1. This means you cannot place a 4 next to a 3 or a 5. For every digit you place, you must eliminate that digit ±1 from all orthogonal neighbours. This propagates eliminations across the entire board immediately after every placement.
Which digits are most affected by the non-consecutive rule? ▾
Digits 1 and 9 can only be invalid next to 2 and 8 respectively — so they are least affected. Digit 5 cannot be adjacent to either 4 or 6, which is a moderate restriction. Digits 4, 5, and 6 are most affected because they are adjacent to two common digit pairs simultaneously.
Adakah Non-Consecutive Sudoku lebih sukar daripada regular Sudoku? ▾
Yes, typically. The global constraint eliminates many more candidates than standard rules alone. Easy puzzles are accessible and resolve quickly. Hard and expert puzzles compensate with fewer given digits, making the non-consecutive constraint the primary source of all deductions.
What is the best first strategy for Non-Consecutive Sudoku? ▾
After placing each digit, immediately mark all orthogonal neighbours as unable to hold ±1. Scan rows and columns for digits that can now only go in one cell due to these combined eliminations. Digit 5 is particularly useful as a placement anchor — wherever 5 is placed, both 4 and 6 are eliminated from all four neighbours.
How long does Non-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. Non-Consecutive Sudoku rewards players who apply the constraint globally and systematically after every move.
