Fill each cell with 0 or 1.
- →Each row and column must contain an equal number of 0s and 1s.
- →You may never have three identical values in a row.
- →No two rows or two columns may be identical.
- →Some adjacent cells show relation symbols that must be respected: = means same value, and ≠ means different values.
Tip: Start with rows or columns that are almost filled. Use relation clues to deduce remaining cells.
