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. Make the next step deliberately.

Your goal

Solve the Sudoku and make the digits on each arrow path sum to the digit in its circle. The feedback beside the game helps you follow the round. Start with a deliberate move.

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. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.

A useful example

A circle 7 may have an arrow containing 3 and 4 when the normal Sudoku rules also allow it. Apply the same reasoning to the position in your own round. Take a moment to compare.

Watch out for this

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
