This is a mini-game to have some fun!
You have to click on the blank rectangles and they will change of color. You have to find the partner of each rectangle. If you click 2 rectangles of the same color, they will remain colored, so you can continue clicking the other rectangles. The game finishes when you find the color matches of all the rectangles.
