How to play Arrow Sudoku

Arrow Sudoku gives you a focused activity to play in your browser. Solve the Sudoku and make the digits on each arrow path sum to the digit in its circle. Check the relevant rule before repeating a move. Check the rule that explains your first action. Look at what changes after your first action.

This collection contains 8 puzzles. Progress is saved in this browser. The same puzzle can appear again; the collection is not labelled with calibrated difficulty levels.

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. Return to the instructions when a step is unclear.

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. A new-round button replaces the current round.

A useful example

A circle 7 may have an arrow containing 3 and 4 when the normal Sudoku rules also allow it. Use the example as a guide rather than a substitute for reading your board. Keep the controls nearby.

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