I wouldn't make such a generalization here. I know plenty of girls (and women), who love puzzle-games the most, for example such in the style of "Bust-a-Move", "Puyo Puyo", "Dr. Mario", "Tetris", "Columns" and so on. There are fans for every game-genre, if you ask me. And I must also say, as a man, that I enjoy some of these puzzlers as well, especially when they can be played against other human players, or against strong cpu-opponents, so that there's a competition
