Big Must Jump

Big Must Jump is a game on 9bob.net. Two squares enter the screen and move toward each other. All you have to do is touch either side of the screen to jump over the other square. But note that only the big one can successfully jump over the small one. So you have to be quick to decide which side of the screen to tap and time your jumping in order to avoid hitting the other square.
Use your mouse to play the game or tap on the screen
