Try a deliberate move

After a move, check what changed. Decide which rule explains the new state before acting again. 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. Use the instructions to see which actions move you towards it. Follow this game’s rules rather than another version’s.

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. Use the control method described here for this activity. Make sure you are interacting with the game rather than the surrounding page.

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. 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. Read the feedback to see why an action did not have the expected result. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
