Practice with a purpose
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Use the example to check your reasoning.
What counts as success
Fill each row, column and irregular coloured nine-cell region with 1–9 once. The feedback beside the game helps you follow the round. Return to the instructions when a step is unclear.
The playing sequence
- 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.
How to use the 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.
One way to understand the rules
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Your next round may have a different position, so inspect it before acting. Read the matching step again.
Keep this in mind
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Check the rule before repeating the action. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
