2 puzzles per page; 140 puzzles in total; level of difficulty is easy with 10x10 grid; all puzzles include solutions at the end; there is always just one answer to each puzzle. The guidelines for solving each binary problem are as follows: 1. There should be a zero or a one in each box. 2. There can't be more than two equal integers next to or below each other. 3. There should be an equal number of zeros and ones in each row and column. 4. Each row and column have their own identity. As a result, no row can be precisely the same as another row, and no column can be exactly the same as another column. 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.
