Teknik Penyelesaian untuk Tahap Pakar
| Teknik | Penerangan | Tahap |
|---|---|---|
| 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. | Pemula |
| 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. | Pemula |
| 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}. | Pertengahan |
| Isolated Digit Detection | A digit surrounded on all four sides by non-bar edges has no consecutive neighbour — highly constrained within a local area. | Lanjutan |
Teknik untuk Dikuasai pada Pakar
- Teknik X-Wing — 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.
