It’s you against Uncle Sam. He’s stars (blue) and you’re stripes (red). Working horizontally (right to left, or left to right), click on any white square and change it red. Meanwhile, Uncle Sam will work vertically (top to bottom) to turn white squares blue.

The first one to complete a solid line from one end of the grid to the other wins. Can you connect before Uncle Sam? If not, you may be playing Stars and Stripes Forever!
