One thing that is crucial not only in seduction but in pretty much every conversation is eye contact. An extremely simple "game" I play while walking down the street, buying groceries, etc. is to stare directly into people's eyes. Let me explain.

When walking down the street stare into other people's eyes until they leave your line of sight. If you look away first you "lose", if they look away first you "win". That's it. You may not consider this as a "game" but it helps with building confidence and getting comfortable during lengthy eye contact.

Obviously, this will help tons with women but it'll also help with various other things such as scoring that job because you had strong, confident eye contact during the interview.

Edit: Sorry about my wording. By stare I mean look straight into their eyes. If they break eye contact, you break too.
