Teknik Pemecahan untuk Tingkat Ahli
| Teknik | Deskripsi | Level |
|---|---|---|
| Immediate Candidate Halving | Marked cells instantly reduce to 5 odd candidates (1,3,5,7,9) or 4 even candidates (2,4,6,8). Apply this before any other technique. | Pemula |
| Parity Counting per Box | Count how many odd-marked and even-marked cells are in each box to verify the digit distribution is achievable. | Menengah |
| Parity-Chain Elimination | If a row must contain exactly four even digits, and three positions are already even-marked, the fourth must come from the remaining unmarked cells. | Menengah |
| Parity X-Wing | When parity restricts a digit to exactly two rows and two columns, form a parity-based X-Wing for cross-elimination. | Lanjutan |
Teknik untuk Dikuasai di Ahli
- Teknik X-Wing — Expert grids shade fewer cells, but every shaded cell still halves a fish's candidate set — anchor your X-Wing rows on the parity marks that survive.
- Swordfish technique — A Swordfish on an even digit only needs to cover even-legal cells, which shrinks the pattern space dramatically — expert odd/even endgames usually hinge on one.
