如何玩杀手数独
棋盘以带有预填数字作为线索开始。你的线索是 笼子和 （单元格角落的小数字）。填充每个笼，使数字之和等于该总数，且笼内数字不重复。所有标准数独规则仍然适用（每行、每列和每个3×3宫都包含1-9）。

你必须记住的强制笼子组合
关键解题技巧
45法则
每行、每列和每个3x3宫的和都是 45。如果一行中所有笼都已知，除了一个单元格，缺失值 = 45 - (该行所有其他笼总和)。这是杀手数独中最强大的单一技巧。
专家提示 -
给定数字为零时，45法则是你唯一的切入点。在放置任何数字之前，跨多个单元进行内格/外格推理。需要笼子重叠计数和裸子集 - 预计从一开始就保持完整的候选数网格。

专家 级别的解题技巧
| 技巧 | 描述 | 级别 |
|---|---|---|
| Cage Sum Elimination | Each cage has a fixed sum. Use the sum and the number of cells to calculate which digits are possible — e.g. a 2-cell cage summing to 3 can only be {1,2}. | 初级 |
| No-Repeat Rule | Digits cannot repeat within a cage. Combined with sum constraints, this eliminates many candidates immediately. | 初级 |
| 45法则 | Each row, column, and box sums to 45. Subtract known cage totals within a unit to find leftover cell sums — often isolating a single value. | 中级 |
| 内格和外格 | An innie is a cage cell inside a unit whose sum reveals a digit; an outie is outside. These provide single-cell deductions without full candidate tracking. | 中级 |
| 笼子重叠计数 | When a cage spans two boxes or rows, use subset counting to pin down which digits appear in the overlap cells. | 高级 |
| Naked Subset in Cages | If a group of cages within a unit accounts for exactly n cells using n digits, those digits are locked to those cells and removed from all other unit cells. | 高级 |
在专家需要掌握的技巧
- X翼技巧 — Expert killers withhold single-combination cages, so opening progress is slow — alternate 45-rule sweeps with X-Wing scans, as each elimination re-prices every cage it touches.
- Swordfish technique — Once cage logic confines a digit to matching columns across three rows, the Swordfish elimination feeds straight back into the cage sums — the expert killer's closing argument.

Keeps the sum-clue arithmetic but moves it onto diagonals where digits may repeat — a deliberate twist on your cage instincts.

Another sum-driven puzzle: instead of cage totals you deduce which digits sit between the 1 and the 9 in each row and column.
