Løsningsteknikker for Ekspert-nivå
| Teknikk | Beskrivelse | Nivå |
|---|---|---|
| Negative Constraint Power | Where no bar appears, the two cells are guaranteed non-consecutive. Every unmarked adjacent edge tells you something — treat absent bars as constraints. | Nybegynner |
| Bar Pair Enumeration | A bar means the digits differ by exactly 1. List all valid pairs: (1,2), (2,3), …, (8,9). Use row/column context to narrow which pair fits. | Nybegynner |
| Consecutive Chain | Three cells connected by two bars form a run of three consecutive digits (in some order). Enumerate the 7 possible runs: {1,2,3}, {2,3,4}, …, {7,8,9}. | Middels |
| Isolated Digit Detection | A digit surrounded on all four sides by non-bar edges has no consecutive neighbour — highly constrained within a local area. | Avansert |
Teknikker å mestre på Ekspert
- X-Wing-teknikk — Expert consecutive endgames alternate bar-chain enumeration with fish — when a chain forces a digit out of three cells of a row, check whether an X-Wing just formed.
- Swordfish technique — Long bar chains synchronise digit placement across parallel rows; a Swordfish on a chain-locked middle digit typically delivers the final breakthrough at expert level.

Non-Consecutive Sudoku
The exact inverse rule — adjacent cells must never differ by 1 — so your bar logic flips into a global elimination engine.
Kropki Sudoku
Adds a second marker type (the doubling black dot) to the consecutive logic you already read fluently.
Anti-Påfølgende Sudoku
Takes the no-bar half of this puzzle and applies it everywhere: no neighbouring cells may be consecutive, no markers given.
