Sulit Palindrome Sudoku
Digit di sepanjang setiap garis yang ditandai dibaca sama dari depan dan belakang. Setiap palindrom mencerminkan logikanya sendiri.
Sulit Palindrome Sudoku. Garis lebih panjang dan lebih sedikit petunjuk — harapkan rantai palindrom mengalir dan tanda-pensil pelacakan.

Teknik Pemecahan untuk Tingkat Sulit
| Teknik | Deskripsi | Level |
|---|---|---|
| Mirror Pair Identification | In a palindrome of length L, cell i and cell L+1−i must share the same digit. Identify all mirror pairs before solving. | Pemula |
| Centre Cell Freedom | The central cell of an odd-length palindrome has no mirror constraint — it is only restricted by standard row/column/box rules. | Pemula |
| Mirror Propagation | Once one cell of a mirror pair is determined, immediately set its partner to the same value. | Menengah |
| Multi-Palindrome Intersection | If two palindromes share a cell, that cell must satisfy both palindrome relationships simultaneously. | Lanjutan |

Teknik untuk Dikuasai di Sulit
- Hidden Pairs technique — Hard palindrome grids overlap lines so a cell mirrors into two different partners — intersecting three candidate lists exposes pairs invisible to any single unit scan.
- Teknik X-Wing — An elimination at one mirror cell exports to a distant row, so fish patterns assemble in rows the palindrome line never touches — check mirrors after every X-Wing.
