Build a steady rhythm
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. Refer to the controls when needed.
Your goal
Fill each row, column and irregular coloured nine-cell region with 1–9 once. Keep that objective in view throughout the round. The example below illustrates a decision.
Step by step
- 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.
Controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. A careful first action helps you become familiar with the layout. Make sure you are interacting with the game rather than the surrounding page.
A useful example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Compare this with the rule that governs the move. 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. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
