While basketball is an awesome game, it does have a certain problem; the balls bounce so much that in some cases they get lost. Recently, that has been happening far too often for comfort, which is why you have been hired to find them in Hidden Basketball. In Hidden Basketball you simply use the mouse in order to move your cursor, and your left mouse to click on a ball. Keep in mind that while you can click anywhere in the picture, a click in the wrong place is going to count as a mistake; make five of them and the game is over. At first you may not see any balls, but keep looking close as they are indeed there; they simply blend in with the background so well. And so, good luck making use of your eagle vision to recover all the lost basketballs so the players can once again enjoy their great sport.
