Controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Contact us with the game and device if a control does not respond.
A useful example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Compare this with the rule that governs the move. Check the stated objective.
Watch out for this
Repeated digits in a run are forbidden even when the sum matches. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
