Partners show hands with a number of fingers up. First to say sum wins.
Players find a partner and face each other. Each player puts their hands behind their back. On the count of three both players put their hands in front of them with a number of fingers up. The first one to say the total number of fingers up (their own hand plus their partner's) wins.
This game works well with a large group of people if the facilitator says once you have lost, sit down, and winners, continue finding other people standing up until there is one winner remaining.
