How to solve
- Zeros and ones: Fill every square with a 0 or a 1.
- No three in a row: Never put three 0s or three 1s next to each other in a row or column.
- Balance: Every row and column holds the same number of 0s and 1s, and no two rows or two columns are the same.
- Signs: An = between two squares means they match; an x means they differ.
