How to Play

Fill the 9×9 grid so every row, column, and irregular region contains digits 1–9. Regions are shown by color and thick borders.

👆

Click a cell to select it, then press a number 1–9 to place it.

🧩

Unlike standard Sudoku, regions are irregular shapes instead of 3×3 boxes. Each colored region must contain digits 1–9 exactly once.

✏️

Toggle Notes mode (N key) to pencil in candidates.

🔴

Conflicts are highlighted in red. A cell conflicts when the same digit appears in its row, column, or region.

💡

Use up to 3 hints. Each hint reveals a cell's value and explains the logic.

About expert jigsaw sudoku

Expert jigsaw sudoku pushes you into advanced territory: pointing pairs across irregular boundaries, X-Wings where the columns intersect multiple oddly shaped regions, and chain techniques that require tracking constraints across the entire grid. The irregular regions make these techniques harder to spot than in standard sudoku because nothing lines up neatly. Pencil marks are not optional here. Use them, and check your region boundaries carefully before making eliminations.
