Comment jouer au Sudoku Non-Consécutif
Les règles standard du Sudoku s'appliquent. Règle supplémentaire : deux cellules orthogonalement adjacentes (partageant un bord) ne peuvent pas contenir des chiffres consécutifs. Si une cellule contient 5, les quatre voisins doivent éviter 4 et 6.

Qu'est-ce que Sudoku Non-Consécutif ?
Non-Consecutive Sudoku impose une contrainte globale : deux cellules qui partagent un bord (orthogonalement adjacentes) ne peuvent pas contenir de chiffres consécutifs. Donc si une cellule contient 5, tous ses voisins doivent éviter 4 et 6. Cette seule règle limite considérablement les placements de candidats et peut réduire un nombre standard de givens tout en produisant un puzzle résoluble de manière unique.

Comment résoudre Sudoku Non-Consécutif
| Technique | Ce qu'il fait | Niveau |
|---|---|---|
| Global Candidate Pruning | For every filled cell, remove its ±1 neighbours from all orthogonally adjacent cells immediately. | Avancé |
| Digit 5 is Most Constrained | 5 cannot be adjacent to 4 or 6. Use this to restrict placement of 5 across the entire grid. | Avancé |
| Chain Propagation | Placing a digit propagates constraints along rows and columns, often triggering a cascade of forced placements. | Avancé |
| Forbidden Pair Maps | Build a map of forbidden digit pairs for each adjacent pair of cells and use it to eliminate candidates systematically. | Avancé |

Foire aux questions
Qu'est-ce que 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.
Le Non-Consecutive Sudoku est-il plus difficile que le Sudoku régulier ?
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.
