Blockuku by Quan Trong FREE

 Blockuku comes from Quan Trong. The object is to place the shapes into the grid to match the numbers on the horizontal and vertical axes.

There are 78 levels and they go pretty fast. Lots of easy levels.  At the moment, I've done about 65. They're getting tougher now.

What could be better:
1. Graphics: change the color scheme every so often.
2. Each grid is a square. This could sometimes be a rectangle.
