Teknik Pemecahan untuk Tingkat Sulit
| Teknik | Deskripsi | Level |
|---|---|---|
| White Dot Pairs | White dots mark consecutive digit pairs: (1,2), (2,3), …, (8,9). Cross-reference with row and column constraints. | Pemula |
| Black Dot Pairs | Black dots mark double-relationship pairs: (1,2), (2,4), (3,6), (4,8). Only these four combinations are valid. | Pemula |
| Negative Constraint | No dot between two cells means they are neither consecutive nor in a 1:2 ratio — a powerful elimination on every unmarked adjacent pair. | Menengah |
| Dot Chain Analysis | A sequence of connected dots forms a digit-value chain. Enumerate valid digit sequences for the entire chain simultaneously. | Lanjutan |
| 1-2-4 and 2-4-8 Chains | A black dot adjacent to a white dot often forces the common 1→2→4 or 2→4→8 chain. | Menengah |

Teknik untuk Dikuasai di Sulit
- Hidden Pairs technique — Chains of dots (black–white runs like 2-4-5) consume candidates along their length; recount the crossing boxes afterwards, because hard Kropki pairs hide where chains intersect units.
- Teknik X-Wing — Digit 9 joins only one white-dot pair (8,9) and no black-dot pair, so dots and their absence rapidly pin 9's legal cells — fish on 9 first in hard Kropki.

Sudoku Berurutan
Isolates the white-dot half of kropki: bars mark consecutive neighbours and silence means never consecutive.
Sudoku Lebih Besar
Adjacent-cell relationships again, but as inequalities — order information instead of difference and ratio.
