Fred must stamp "towers" into the ground by jumping on them. A "square" consisting of four towers automatically disappears in the ground when all four towers have the same height. The slim, high display at the lower left shows, how many levels of each tower need to be reduced or respectively how many are left. It can happen that all possible tower combinations are gone, but they were not high enough. Fred can only stand on towers, on normal ground he will die. You need to collect energy pills, or else Fred gets sick. Furthermore, there are bonus diamonds to get additional points.
