Basically, you have to put the numbers 1 - 9 in each of the rows, but you can't have the same numbers in either row vertically or horizontally.

^ There's a finished one. Idk it's hard to explain, but you can see it's like cut up into little sections, 9 sections overall, and you have to get 1-9 in those sections, which adds up to it being the numbers 1-9 in every row. But you can't have, for example, the number '1' twice in the same row vertically or horizontally.
I have no idea if any of that made sense

It's probably easier for you to look at the picture of the finished sudoku & work it out
