Read before acting

Read one step at a time and try it on the playing area. Match the instruction to the control you use. Refer to the controls when needed.

Your goal

Solve the Sudoku and make the digits on each arrow path sum to the digit in its circle. Keep that objective in view throughout the round. 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. Read a button’s label before selecting it. Check any mode label before starting.

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. 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. A different version of the game may use a different rule. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
