Binary puzzles, if you love puzzling, you should try a binary puzzle. The goal of a binary puzzle is to have the same number of zeros (blue) and ones (green) in every row, and in every column. Each game starts with a grid with a few boxes already filled in. This must be completed further with the following lines: - Every row and every column is unique. - Each row and column contains as many zeros (blue) as ones (green). - There are no more than two neighboring tiles with the same number / color. With thousands of unique puzzles, every game will be different.
