Introduction
If the buttons on your Connect Four have been damaged, you will need to replace them. If the buttons are torn, you will need to purchase a new button sheet. If the buttons are unaligned, simply readjust the button sheet. In order to get to the buttons, you will have to remove the casing on the back of the device. This requires a Phillips head screwdriver.
