Chopsticks is a logic hand game with its origins in Japan. It is played the world over.

Players extend hands to towards each other with one finger out and take it in turns to tap each others hands. The tapped hand extends more fingers equal to the fingers on the hand that tapped it. A hand full of fingers is "knocked out". There are many variants of rules, many of which are captured here, including splitting fingers between hands, different number of hands and different number of fingers per hand.
