Block Trouble

Block Trouble is a game about the mind. Your only job is to click the unique block onscreen. There are 16 blocks made up of 6 colors: purple, red, blue, white, yellow and green. One of these colors is only present once. This is the one you click on. The only problem is, you have very little time to do so! Start off with 2 seconds and make your way to less than one. See which of your friends can reach the highest score!
