Ddakji (Korean: 딱지; RR: ttakji; MR: ttakchi)[a] is a traditional Korean toy used primarily to play variants of a category of games called ddakji chigi (딱지치기; ttakji chigi; ttakchi ch'igi; lit.
[3] In South Korea, the game was particularly popular amongst school children in the late 20th century.
Pre-made round ddakji with cartoon characters printed on them were traded and collected among players.
Ddakji are usually made by folding thick paper into a square, rectangular, or round shape.
Players would use alternate throwing techniques based on these characteristics, and create their own ddakji to enhance certain properties.
[1][6] This reportedly has resulted in some players attempting to cheat by covertly generating air flow using their clothes or body and not with the ddakji.
[1][4] One such additional rule is creating a boundary for the play area, where ddakji that move out of bounds are disqualified.
[7] After the liberation of Korea, paper became increasingly available to the general public, and the practice of folding ddakji became solidified.
[8] Due to the popularity of the show, ddakji and other traditional Korean games featured in it were played around the world.
[11] The South Korean variety show Running Man occasionally features ddakji in its missions.
