Puchi Puchi Virus does not resemble the ordinary puzzle game. The usual object drop style was replaced with a more intuitive system of object linkage. The object is to form at least a single triangle formation by linking viruses together and erasing them from the screen. Victory conditions vary from mission to mission, but erasing all of the viruses is the fundamental rule of this game. Erase all the viruses and you win, but if the screen gets filled with the emerging viruses you lose.
