Try a deliberate move

After a move, check what changed. Decide which rule explains the new state before acting again. 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. Take a moment to understand the current position.

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. A careful first action helps you become familiar with the layout. Check any mode label before starting.

A useful example

A circle 7 may have an arrow containing 3 and 4 when the normal Sudoku rules also allow it. Focus on why the action is allowed, not only its outcome. Look for the relevant detail.

Watch out for this

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. 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.
