Alternatively, give each player 10 pieces of candy that they can eat throughout the game.
Play rock, paper, scissors if you can’t decide who goes first, or choose the youngest person in the room.
Once you put one finger down, keep that finger down for the rest of the game. If you’re using candy, eat one candy instead of putting down one finger.
Repeat the game as many times as you like. It doesn’t involve any supplies, and it’s a great way to get to know people.
