Takuzu and binairo grids in 6×6, 8×8 and 10×10
Updated Sep 17, 2026
A binary puzzle uses only two symbols, 0 and 1, and three rules: never three of the same symbol in a row or column, an equal count of each symbol in every row and column, and no two rows or columns identical. That is the whole rule set, which makes it one of the easiest logic puzzles to explain to a beginner and one of the most satisfying to scale up — a 10×10 grid with the no-triples rule produces long forced chains.
