I've got laid a few times after running the cube. Perhaps I still would have got laid had I been talking about my favourite cake, but I would find that boring to talk about.

I'm interested in psychology and symbolism so I find the cube quite fun. I've done it with my students, with guys, and with my friends' girlfriends, so I don't just do it to get women, but if it happens that's a nice bonus.

It's not some magic spell that gets you laid; it's just a fun game that can make people smile and if the girl likes you anyway it might take you that step closer. People genuinely get enjoyment out of it. What's wrong with that?
