Follow the steps for Jigsaw Sudoku

Make Jigsaw Sudoku your next activity in the game library. Fill each row, column and irregular coloured nine-cell region with 1–9 once. Look at what changes after your first action. Make your first input carefully and watch the result. Choose a clear next step rather than rushing through the instructions.

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.

Something to practise

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.

What you need to achieve

Fill each row, column and irregular coloured nine-cell region with 1–9 once. Keep that objective in view throughout the round. Start with a deliberate move.

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.

Your inputs

Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. On a smaller screen, keep the active part of the board within view. Return to the rules if the result is unexpected.

An example to follow

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. Notice the change in the playing area.

A common point of confusion

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
