Fill in the blank squares so that each horizontal line, each vertical line and each sub-block (3 squares x 3 squares) contain the numbers 1-9. There's no maths involved. The grid has numbers, but nothing has to add up to anything else. You solve the puzzle with reasoning and logic. That's all there is to it!!
