Binairo also known as Takuzu is a logic puzzle with simple rules and challenging solutions.

The rules are simple. Binairo is played on a rectangular grid with no standard size. Some cells start out filled with black or white circles. The rest of the cells are empty. The goal is to place circles in all cells in such a way that:
1. Each row and each column must contain an equal number of white and black circles.
2. More than two circles of the same color can't be adjacent.
3. Each row and column is unique.

Click a cell with the mouse to place a black circle, click again to make it white.

Where do I start?



You can't have more than 2 adjacent of the same color so look for 2 of the same color next to each other:

There should be a black circle next to the 2 white ones.

Or you can look for 2 of the same color with 1 empty cell between them:

There should be a black circle between the 2 white ones.


Equal number of white and black circles?


On a 6x6 grid you should have 3 white and 3 black circles on each row and on each column. So if you already have 3 whites:

The empty cells should contain black circles.

Q. Each row and column is unique?

Check this scenario:

The second row cannot be the same as the first one (it should be unique). So it should be like this:


* All the above apply to columns as well
