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

Teknikker at mestre på Svær
- Hidden Pairs technique — The ±1 eliminations quietly strip candidates until two digits share just two cells of a unit — recount after every cascade, because hard grids bury their pairs under neighbour logic.
- X-Wing-teknik — With so few givens, hard non-consecutive grids rely on fish: the global constraint pre-thins candidates so X-Wing rectangles form earlier than the sparse grid suggests.

Konsekutive Sudoku
The marked counterpart of your global rule — bars show exactly where consecutive neighbours sit, and absence means what you're used to.
Anti-Konsekutiv Sudoku
The same global neighbour restriction under its other name — an alternative puzzle pool built on identical logic.
Anti-Ridder Sudoku
Another unmarked anti-rule, pushing the forbidden relationship from orthogonal neighbours out to knight-move cells.
