Make the controls familiar

Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Use the example to check your reasoning.

Your goal

Solve the Sudoku and make the digits on each arrow path sum to the digit in its circle. Read that aim before choosing your first action. Check the rules when you are unsure.

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. On a smaller screen, keep the active part of the board within view. Make sure you are interacting with the game rather than the surrounding page.

A useful example

A circle 7 may have an arrow containing 3 and 4 when the normal Sudoku rules also allow it. Compare this with the rule that governs the move. Choose a deliberate next step.

Watch out for this

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Check the rule before repeating the action. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
