Dear Miuccia

Maybe a poster framed, showing the playfield layout and features. Especially if it's a game you have.

If they show interest in the poster, point out details about the game, then show them again on your game. Invite them to try a shot or two.

If that doesn't work, slap them upside the head and invite new people over. Give them a chance.
