困難 不規則數獨
拼圖形狀的區域取代了3×3宮。行、列和不規則區域都必須包含1-9。無需下載，無需登錄。
困難 不規則數獨。複雜的區域形狀，給定數字較少——預計跨區域的指向對、隱藏集和持續的 候選數 工作。

解謎技巧（困難 等級）
| 技巧 | 描述 | 等級 |
|---|---|---|
| Region Identification First | Identify all 9 irregular regions by their colour coding before solving. Region membership determines the third constraint unit for each cell. | 初學者 |
| Region Counting | Each region must contain 1–9. Counting completed rows and columns reveals how many of each digit can still fit in each region. | 中級 |
| Region–Row/Column Intersection | If a digit within a region is confined to one row or column, eliminate it from the rest of that row or column. | 中級 |
| Irregular Naked Subsets | Apply naked pairs and triples within each irregular region exactly as you would within standard 3×3 boxes. | 進階 |

在 困難 需要掌握的技巧
- Hidden Pairs technique — Irregular region geometry hides pairs in cells that share a region but no row or column — deliberately recount candidates region-by-region or you will never see them.
- X翼技巧 — Rows and columns are unchanged by jigsaw regions, so classic X-Wings still work — and they're often the only move left when region logic stalls in hard puzzles.
