How to play Arrow Sudoku

Choose a round of Arrow Sudoku and settle into its rules. Solve the Sudoku and make the digits on each arrow path sum to the digit in its circle. Look at what changes after your first action. Treat the first round as a chance to learn the controls. Choose a clear next step rather than rushing through the instructions.

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.

Notice the feedback

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. 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. An attractive position is not enough unless the goal is met. Keep the controls in easy reach.

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. Read the example below alongside these instructions.

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. Read the matching step again.

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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
