This one will drive you nuts!! The object of the game is to move the red block around without getting hit by the blue blocks or touching the black walls. If you can go longer than 18 seconds you are phenomenal. It's been said that the US Air Force uses this for fighter pilots. Theyare expected to go for at least 2 minutes.
Give it a try!! http://tinyurl.com/56t9u
