Squid (Korean: 오징어, ojingŏ), is a children's game played in South Korea. The game is named as such because the shape of the playing field drawn on the ground resembles that of a squid. There are regional variations of the name such as "squid gaisan" (with gaisan thought to be a variation of the Japanese word kaisen 開戦, 'to start a war'), or "squid takkari".[1] It is a multiplayer game, and the game is divided into two teams, offensive and defensive. There are two main purposes, either for the attackers to achieve the purpose of the attack, or for the teams to annihilate each other.[2]
