Game rooms provide a place to gather family and friends, host parties and have a great time. Adding a decorative theme to your game room makes it reflect your tastes and provides guidance when choosing accessories, paint colors and furniture. One example theme for a game room in a house is casino theme. A casino theme might be fitting for a game room in a house, especially if you and your friends enjoy card games, such as poker. Line round wooden tables with green felt or purchase poker tables with wells for poker chips. To make the room comfortable for children, stack an assortment of board games and children’s card games on a bookshelf and decorate part of the room with a television and leather couch where children and adults can lounge. Instead of traditional throw pillows, purchase a few large, stuffed dice to prop on the couches to enhance the gambling theme.
