How to play Jigsaw Sudoku

Try Jigsaw Sudoku at your own pace and keep its objective in view. Fill each row, column and irregular coloured nine-cell region with 1–9 once. Choose a clear next step rather than rushing through the instructions. Read the objective before making your first input. Check the relevant rule before repeating a move.

This collection contains 6 puzzles. Progress is saved in this browser. The same puzzle can appear again; the collection is not labelled with calibrated difficulty levels.

Focus on one rule

Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Make the next step deliberately.

Your goal

Fill each row, column and irregular coloured nine-cell region with 1–9 once. The feedback beside the game helps you follow the round. The example below illustrates a decision.

Step by step

1. Select an editable cell.
2. Enter a value using the keypad or keyboard; Notes stores candidates.
3. Read the region, cage, arrow or outside clues alongside the normal constraints.
4. Check entries verifies the completed board; Undo reverses your last input.
5. New puzzle selects another included puzzle.

Controls

Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Use the control method described here for this activity. Return to the rules if the result is unexpected.

A useful example

The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Apply the same reasoning to the position in your own round. Keep the controls nearby.

Watch out for this

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. A different version of the game may use a different rule. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
