Publisher's Synopsis
Binary, also known as Takuzu, is a logic puzzle involving placement of 1's and 0's, on a rectangular grid. The rules are simple. Some cells are filled with 1's and 0's. The rest of the cells are empty. The goal is to place 1's and 0's in all cells in such a way that:
1. Each row and each column must contain an equal number of 1's and 0's.
2. no more than two of either number adjacent to each other .
3. Each row and column is unique, there can be no identical rows or columns.
Similar to Sudoku, each puzzle begins with several squares in the grid already filled.
