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 cirecles of the same type.
4. Two cells with a "x" sign between them should contain cirecles of the opposite type.

Starting puzzle
Start

Fill every cell with either a black or white circle.

Three adjacent same color
Wrong

Three circles of the same color in a row. No more than two of the same color can be adjacent.

Unequal count in row
Wrong

Too many black circles in this row. Each row and column must have an equal number of black and white circles.

Sign constraints violated
Wrong

The "=" sign means both cells must be the same color. The "×" sign means they must be opposite colors. Both are violated here.

Duplicate rows are allowed
OK

Unlike regular Binairo, duplicate rows and columns are allowed in Binairo+.

Correctly solved puzzle
Solved

All cells filled. Equal black and white per row/column, no three adjacent, and all sign constraints satisfied.


Zooming
Pinch with two fingers to zoom in/out. If you use a mouse you can use the scroll button.

Moving
Tap and drag to move the puzzle. If you use a mouse you can click and drag with the middle (scroll) button.

Marking
You can tap/click individual cells to change their state.

When this mode is selected from the game menu the state of the cell is going from "empty" to "white" to "black" to "empty". If you use the right mouse button the states rotate in the opposite order
If you select one of these modes... Simply put - what you see is what you get.
You can also mark more than one cell at a time. Tap and hold a bit, then move your finger to draw a line.
