Focus on one rule

Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. 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. Use the instructions to see which actions move you towards it. Review the board or playing area as it changes.

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. Use the visible help when you are unsure of the next input.

A useful example

A circle 7 may have an arrow containing 3 and 4 when the normal Sudoku rules also allow it. Your next round may have a different position, so inspect it before acting. 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. Check the rule before repeating the action. After a move, check what changed. Decide which rule explains the new state before acting again.
