I used python

You should specify the language. Sometimes it's only 1 language that has missing tests.

Insufficient tests. Sudoku rules checked only in squares but not in rows or columns. Instructions incomplete as well.

That is true but it is not specified in the instructions that it should be validated as well. It only says that the squares may only contain integers in 1..N range.

Thanks!

Very nice kata. It is great when there is a short, simple solution once you understand the problem.
