A useful example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.

Repeated digits in a run are forbidden even when the sum matches. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
