Various colored shapes will appear randomly on the page.
Your job: click them as quickly as you can!

Click Me!

Note: If you decide to click the Debug! button, notice the red border expands and contracts as you change the size of the window; also notice that the Top value does not seem to match the offset from the top of the window and the shape sometimes fall outside the red border. Still trying to figure that one out!

Note: If you click the Finish button and nothing happens (and/or if you do not see any colored shapes to click after five minutes), just remember that this game is FREE! Close the browser tab or page and have a nice day!

Confession: I had trouble getting box position to be random because I left "px" off the randomly generated number! - 26 Nov 2014; still having trouble managing display limits on 29 Nov 2014
Big "thank you" to my friend Peter Konieczko who provided assistance to clear up some (but not all) of my confusion about the display area (on 29 Nov 2014)!
