How to play Jigsaw Sudoku

Take a moment with Jigsaw Sudoku before moving to another game. 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. Keep the instructions close while learning this activity. 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. Use the example to check your reasoning.

Your goal

Fill each row, column and irregular coloured nine-cell region with 1–9 once. Keep that objective in view throughout the round. Notice how the game responds to your input.

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. Read a button’s label before selecting it. Contact us with the game and device if a control does not respond.

A useful example

The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.

Watch out for this

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Check the rule before repeating the action. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
