Publisher's Synopsis
Binary Puzzle (also known as "Binairo," "Takuzu," "Tohu wa Vohu," "Binoxxo") 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.
