I've played or observed a handful of games involving some sort of hand/rhythm/chanting component. Crucially they all have no equipment/items needed to play.
- 가위바위보 "rock, paper, scissors"
- 토끼 토끼 토끼; 당근 당근 당근... (some rhythm and hand gestures accompanying this; you lose if you do the wrong one)
Is there a general term for these sorts of games? Are there any particularly well know examples? Are these games known to come from elsewhere, or do many originate in Korea?
