Best Free Binairo
Fill the grid with 0s and 1s — no three alike, balanced counts, every line unique.
How to play
- Cycle the cells. Click an empty cell to set it to 0, click again for 1, and once more to clear it. Pre-filled clue cells stay fixed.
- Apply the three rules. Never put three of the same number in a row or column, keep an equal count of 0s and 1s in every line, and make sure no two rows or two columns match.
- Fill the whole grid. When every cell is filled with no conflicts left, the puzzle is solved.
About Binairo (Takuzu)
Binairo, also known as Takuzu or Binary Puzzle, is a logic game played on a square grid that you fill entirely with 0s and 1s. Three simple rules drive every deduction: no more than two of the same number may sit next to each other in any row or column, each row and each column must contain an equal count of 0s and 1s, and no two rows — and no two columns — may be identical. Some cells start filled to anchor the solution; click an empty cell to cycle it through 0, 1 and back to blank. Every board is generated fresh from a valid completed grid. The grid grows with difficulty — 6×6 on easy, 8×8 on normal and 10×10 on hard. No signup, no download, nothing uploaded.
