Free pattern -Sudoku Square

[Kitty]

I was trying to follow a diagram for another square and I did this one that doesn't look like the one in the diagram , but it does look like an empty SUDOKU . I didnt find anything on the internet that looks like this so i guess its my pattern design. To edge and stabilize the square, I did sc in each stitch except the corner where I did sc, ch, sc in the middle corner stitch.
