Define a rectangle by clicking on its opposite corners. Then click on Mirror, Flip or Rotate button to alter the rectangle. You are trying to rearrange balls so they end up in their own colour's quarters. The percentages show how successful you are so far. After a certain number of moves, all balls of the wrong colour for the quarter will disappear. See how many balls you can keep!
If you chose an unlimited game, then you can carry on until you have all balls in the correct place.
The easy game allows you to define a line to change. The hard game requires all rectangles to be proper rectangles.
