Cara bermain Non-Consecutive Sudoku
Peraturan Sudoku standard terpakai. Peraturan tambahan: tiada dua sel bersebelahan secara ortogon (berkongsi tepi) boleh mengandungi digit berturutan. Jika sel mengandungi 5, keempat-empat jiran mesti mengelak 4 dan 6.

Apakah Non-Consecutive Sudoku?
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.

Cara Menyelesaikan Non-Consecutive Sudoku
| Teknik | Apa yang dilakukannya | Tahap |
|---|---|---|
| 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 |

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.
