Each couple should bring a dessert. Have some sodas, coffee, or tea on hand to offer your guests. You could play Uno, Phase 10, Rummy, or whatever you enjoy. If you have a large group of friends, you could set up several tables and have a different game at each table. If there are children, let them play their own card games, like Go Fish, or other age-appropriate game, or set them up with a child-friendly movie. You might want to have the rules of the game close by in case someone in your group doesn’t know the game.
