Read before acting
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Keep the objective visible.
Your goal
Fill rows, columns and boxes with 1–9 once. Cage digits cannot repeat and must add to their clue. 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. Return to the rules if the result is unexpected.
A useful example
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Apply the same reasoning to the position in your own round. Verify the rule before continuing.
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
