About Add Cross

Add Cross is a pencil puzzle where you fill blank squares with numbers from 1 to 9 to match the numbers in the problem squares. Connected blocks cannot contain the same number, but blocks separated by hint squares can. Complete every blank square to solve the puzzle. The game distinguishes confirmed numbers, temporary numbers and numbers that are not yet confirmed.
