专家 级别的解题技巧
| 技巧 | 描述 | 级别 |
|---|---|---|
| Diagonal Enumeration | For each clue, enumerate all combinations of N digits (allowing repeats, 1–9) that sum to the clue value. | 初级 |
| Repeating Digits Allowed | Unlike Killer cages, Little Killer diagonals can repeat digits as long as standard row/column/box uniqueness is preserved. | 初级 |
| Short Diagonal Logic | A 1-cell diagonal directly gives that cell's digit. A 2-cell diagonal with clue C has limited pairs — enumerate them immediately. | 中级 |
| Cross-Diagonal Intersection | When two diagonals share a cell, the shared cell must satisfy both sum constraints simultaneously. | 高级 |
| Row/Column Interaction | A diagonal cell belongs to a row, column, and box — combine Little Killer sum constraints with standard uniqueness rules. | 中级 |
在专家需要掌握的技巧
- X翼技巧 — Expert grids give almost no cell digits, so after the opening sum deductions, X-Wings on the sum-starved high digits carry the middle game.
- Swordfish technique — Parallel clue diagonals impose matching digit profiles on the rows they cross; a Swordfish across three such rows typically unlocks the expert endgame.

相关变体
杀手数独
The cage version of the same idea: sum clues with a no-repeat rule that makes the arithmetic tighter than on diagonals.
三明治数独
Also driven entirely by numbers written outside the grid — sums between the 1 and 9 instead of along diagonals.
摩天楼数独
Another outside-clue variant, replacing diagonal sums with visibility counts read from the grid's edges.
