Løsningsteknikker for Ekspert-nivå
| Teknikk | Beskrivelse | Nivå |
|---|---|---|
| Global Candidate Pruning | For every filled cell, remove its ±1 neighbours from all orthogonally adjacent cells immediately. | Nybegynner |
| Digit 5 is Most Constrained | 5 cannot be adjacent to 4 or 6. Use this to restrict placement of 5 across the entire grid. | Middels |
| Chain Propagation | Placing a digit propagates constraints along rows and columns, often triggering a cascade of forced placements. | Middels |
| Forbidden Pair Maps | Build a map of forbidden digit pairs for each adjacent pair of cells and use it to eliminate candidates systematically. | Avansert |
Teknikker å mestre på Ekspert
- X-Wing-teknikk — Expert grids may open with almost nothing placed — chain ±1 eliminations to two-cells-per-row status, then X-Wings finish what neighbour logic starts.
- Swordfish technique — Three-row Swordfish patterns on 5 are the signature expert move here: 5 is the most neighbour-constrained digit, so its candidate grid is the thinnest.

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