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 medium jigsaw sudoku

Medium difficulty drops the given count enough that scanning alone won't finish the puzzle. You'll need to find hidden singles inside the irregular regions, which means tracing each region's boundary to check which digits are already placed. This is where jigsaw sudoku starts to feel different from standard sudoku. A digit might be confined to one cell within a region even though multiple cells look valid at first glance. Take your time with the region colors and border lines.
