How to play Binary Puzzles: The goal of a binary puzzle is to fill in the grid with the numbers 0 and 1 according to the following rules: * There are as many ones as zeros in every row and every column (or one more for odd sized grids). * No more than two of the same number can be next to or under each other. * Each row is unique, and each column is unique.
