Binairo

Binairo (also known as "Binary Puzzle", "Takuzu", "Tohu wa Vohu") is played on a rectangular or square grid. The goal is to fill in the grid with digits "0" and "1" according to the following rules:

• There are as many digits "1" as digits "0" in every row and every column (or one more for odd sized grids).
• No more than two cells in a row can contain the same number.
• Each row is unique, and each column is unique.
