Hi! A themed party is just awesome—your friends are sure to love it. The easiest games to recreate are Chance Cubes or Sabaak, since all you need is a standard deck of cards and two-colored dice. For inspiration and to understand the rules, I recommend reading the article  on the Star Wars News Net portal, which does a great job of explaining the mechanics of these games and their role in the canon. And instead of complicated gadgets, use regular chips or even nuts for betting. Have you already prepared your costumes, or will you just play in your everyday clothes?
