Ask HN: Gender Neutral (or non-brogrammer) hacknight activities

I'm involved in helping run a hacknight. In the past the hacknight has been successful but the activities have included energy drink chugging, halo tournaments, bb-gun shooting and things like that. It's been a lot of fun, but now that I am helping to plan it, I'd really like to introduce some activities and games that appeal to everyone. Basically just want everyone to feel involved/included/interested. Any suggestions?
