What games are suitable for multiple friends to share?

Secret angel (a game I like very much, suitable for the beginning of every activity. You can play a game for a short time, or you can play it for a long time for several months. First of all, randomly assign the angels you take care of, and you are the master. Within a fixed period of time, you must take care of him inadvertently (never let the angel know who the owner is). I also played this game when I was in middle school. In my spare time, I would put a pack of Zhu on the angel's platform. This is my version.
