A small practice goal
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Keep the objective visible.
Understand the aim
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. The example below illustrates a decision.
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.
Getting comfortable with the controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Read a button’s label before selecting it. Avoid pressing the same control repeatedly while a move is being processed.
An example to follow
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Compare this with the rule that governs the move. Choose a deliberate next step.
A common point of confusion
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
