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.

A useful comparison

Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Notice the feedback after each input.

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. Keep the controls in easy reach.

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. Use the example as a guide rather than a substitute for reading your board. Look for the relevant detail.

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