Understand the basics of Jigsaw Sudoku
Start Jigsaw Sudoku by looking at the playing area and its controls. Fill each row, column and irregular coloured nine-cell region with 1–9 once. Keep the game area visible while you use its controls. Compare the starting position with the example in the Guide. Look at what changes after your first action.
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.
Practice beyond the first move
After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.
What you are aiming for
Fill each row, column and irregular coloured nine-cell region with 1–9 once. Use the instructions to see which actions move you towards it. Keep the controls in easy reach.
From the start of a round
- Select an editable cell.
- Enter a value using the keypad or keyboard; Notes stores candidates.
- Read the region, cage, arrow or outside clues alongside the normal constraints.
- Check entries verifies the completed board; Undo reverses your last input.
- 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. Use the control method described here for this activity. A new-round button replaces the current round.
Put the rules into context
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. Choose a deliberate next step.
One detail worth checking
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
