如何遊玩殺手數獨
棋盤以 帶有預填數字作為線索 開始。您的提示是 籠和 (格子角落的小數字)。填入每個籠,使數字總和等於該總數,且籠內數字不重複。所有標準數獨規則仍然適用(每行、每列和每3×3宮都包含1–9)。

你必須記住的強制籠組合
關鍵解題技巧
45法則
每個行、列和3x3宮總和為 45。如果一行中的所有籠都已知,除了一個格子,缺失值 = 45 - (該行中所有其他籠總和)。這是殺手數獨中最強大的技巧。
專家提示 -
在零個給定數字的情況下,45法則是唯一的切入點。在放置任何數字之前,跨越多個單元進行連鎖內外格推論。需要進行籠重疊計數和裸子集 - 預計從一開始就維持完整的候選數網格。

解題技巧:專家 等級
| 技巧 | 描述 | 等級 |
|---|---|---|
| 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}. | 初學者 |
| No-Repeat Rule | Digits cannot repeat within a cage. Combined with sum constraints, this eliminates many candidates immediately. | 初學者 |
| 45法則 | 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. | 中級 |
| 內部和外部 | 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. | 中級 |
| 籠子重疊計數 | When a cage spans two boxes or rows, use subset counting to pin down which digits appear in the overlap cells. | 進階 |
| 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. | 進階 |
在 專家 需要掌握的技巧
- X-Wing 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.

小殺手數獨
Keeps the sum-clue arithmetic but moves it onto diagonals where digits may repeat — a deliberate twist on your cage instincts.
Sandwich數獨
Another sum-driven puzzle: instead of cage totals you deduce which digits sit between the 1 and the 9 in each row and column.
箭頭數獨
Swaps cages for arrows whose shaft must add up to the circled digit — the same combination-counting muscle in a linear shape.
