"To play Angry Faceblocks, all you need to do is click a block and drag your finger to make a rectangle. In order for the rectangle to be eliminated, its four corners must all be the same color. Once every angry faceblock is off the board, you will advance to the next level, where a new color will be introduced on the board. And don't forget about the timer! Try to clear as many blocks as you can because time gets added to the clock when you complete a rectangle!
