To play Sardines you turn all the lights off. Then, one person is selected to hide. All others are put into a room with the door closed and must wait for 3 minutes (may vary, depending on size of home). Then, they all set out to look for the person who is hiding. When someone finds the person who is hiding, they must stay and hide with them. This first person will be the "hider" next round. The last person remaining must find everyone for the round to end.
