Binairo+ also known as Tango (by LinkedIn) 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. Two cells with a "=" sign between them should contain circles of the same type.
4. Two cells with a "x" sign between them should contain circles of the opposite type.
Click a cell with the mouse to place a black circle, click again to make it white.
