Rules

The following rules apply when solving a binary puzzle:

1. Each cell must contain either a zero or a one.
2. No more than two identical numbers may be placed directly adjacent or directly below each other.
3. Each row and column must contain an equal number of zeros and ones.
4. Each row is unique and each column is unique. Thus, any row cannot be exactly equal to another row, and any column cannot be exactly equal to another column. However, a particular row may be filled in the same way as a particular column.

Every binary puzzle has a single unique solution, and each step toward it can be deduced logically. In other words, guessing is never necessary.
