Overview
Squid, also known as 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 , "to start a war"), or "squid takkari". 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.
Gameplay
There are multiple versions of the rules for different areas and groups. Regional names differ.
General rule elements
The home bases for each of the teams are called "houses". The top circle is the house for the offensive team, the bottom rectangle is the house for the defensive team, and the middle triangle is the neutral ground between them.
The objective for the offensive team is to leave their house and move outside the figure around to the bottom of the defensive house (shown "open" on the diagram above), then pass through the figure back into the offensive house.
