6x6 all of us were doing 4x4 first because it was the easiest. We had to buddy up into twos and I buddied up with James. Me and him were really good at it . We did one each so it was faster.
In Sudoku there were blank spots you had to fill them in with a number. You weren't allowed to have the same more number more than once in the same column or row.
Have you done a Sudoku before?
