📖 How to Play Jigsaw Sudoku · Rules & Tips

🎯 Core Rules

Jigsaw Sudoku follows the classic 9x9 logic puzzle format. Only three simple rules:

✨ Each puzzle follows pure deductive logic — no guessing required!

✔️ Each row contains digits 1–9 without repetition
✔️ Each column contains digits 1–9 without repetition
✔️ Each 3×3 box (bold outlined) contains digits 1–9 without repetition

⬇️ Example: a 3×3 box (one of nine) ⬇️

4

5

6

7

8

9

Each 3×3 block must contain all digits 1–9 exactly once

🧠 Advanced Tips

Scanning — check rows/columns to eliminate candidates within a box.
Naked Singles — if a cell sees 8 different numbers in its row/column/box, the missing number is forced.
Hidden Pairs — when two cells in a unit share the same two candidates, eliminate elsewhere.
Pencil marks — use mental notes or candidate tracking to narrow possibilities.

💡 Undo is always available — perfect for learning advanced techniques step by step.
