Shakashaka

Shakashaka (Proof of Quilt) is a logic puzzle with simple rules and challenging solutions.

The rules are simple. Shakashaka is played on a rectangular grid. The grid has both black cells and white cells in it.
The objective is to place black triangles in the white cell in such a way so that they form white rectangular (or square) areas.
- The triangles are right angled and occupy half of the white square divided diagonally.
- You can place triangles only in white cells
- The numbers in the black cells indicate how many triangles are adjacent, vertically and horizontally.
- The white rectangles can be either straight or rotated at 45°
