Try describing the reason for a move or action in one sentence. If the reason is unclear, revisit the rules before continuing.
Your goal

Controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution.
A useful example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell.
