aka Takuzu
by William Wesley
Binary, also known as Takuzu, is a logic puzzle involving the placement of 1’s and 0’s, on a rectangular grid. The rules are simple. Each grid begins with some cells filled with 1’s and some filled with 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 can be adjacent to each other.
3. Each row and column is unique, there can be no identical rows or columns.
