The rules of Binairo are simple:
1) Each row and column must have an equal number of black and white circles.
2) There can be no horizontal/vertical line of three like-color circles.
Starting from a position of fixed circles (indicated by those with dots in the center), one can complete a grid using logic.
In the puzzle below, provided by this website, I have made at least one mistake (hopefully no more than one), and I know this because filling in any of the empty cells would break one of the rules. I am not asking you to solve this puzzle for me necessarily, but rather, I want to know: Is it possible to determine logically where I went wrong without starting over from scratch or randomly erasing cells? What would you do to correct your mistake if you found yourself in this position while solving the puzzle?
