Facebook Games are online games that can be played directly on the Facebook platform. They range from simple puzzles and card games to more complex role-playing and strategy games. Users can play these games solo or compete with friends, making them a popular way to socialize and have fun. Many Facebook Games are free to play, but they often include in-game purchases for additional features or items. These games are designed to be easily accessible, allowing players to jump in and out quickly while enjoying a casual gaming experience with their Facebook friends.
