Crackpots is an Atari 2600 game designed by Dan Kitchen and published by Activision in 1983.
It was Kitchen's first game for Activision; he later did a number of ports to the 2600, including the arcade games Kung Fu Master and Double Dragon. Each level consists of four waves of twelve bugs each; defeat all four waves and the player will move on to a more difficult and faster-paced level. Play then resumes until the building crumbles to the ground.
If six or more bugs enter through the open windows, part of the building will be eaten away, and you will have to replay the level. The patterns vary for different colored bugs. Black bugs will move straight up the building, blue bugs wiggle from left to right, red bugs move diagonally, and green bugs zig-zag between windows.
