Gaga is a fun game for kids. It's like playing tag, but instead of just running around and trying to "tag" someone, you have to use different body movements and poses. You can also make up your own moves and try to outdo your opponents. The goal is to be the last one standing and not get tagged by anyone else. To play gaga, you need to join a group of people, who will stand in a circle and take turns trying to hit another player with their hands or feet. They can also dodge other players and try to stay away from them. Have fun!
