Keelegu

Keelegu is a traditional Korean board game that originated during the Joseon Dynasty (1392–1910). The game is played on a grid similar to a crossword puzzle, with a central square surrounded by concentric layers of squares. Keelegu is often referred to as the "Korean version of Go" due to its strategic nature, though it is distinct in its rules and gameplay.

The objective of Keelegu is to capture the opponent's pieces by surrounding them with one's own stones, while simultaneously protecting one's own. Players take turns placing black and white stones on the board, with the first player typically using black. The game progresses as players expand their territory, aiming to control the central area and surrounding spaces. Unlike Go, Keelegu includes a fixed starting position, where the first player places a stone in the center, and subsequent moves follow a structured pattern.

Keelegu is played on a board with 19x19 lines, creating 361 intersection points where stones are placed. The game emphasizes spatial strategy, requiring players to anticipate their opponent's moves while managing their own expansion. It is considered a mind sport, fostering critical thinking and tactical planning.

While less widely known than Go, Keelegu retains cultural significance in Korea and is sometimes played in educational settings to teach strategy and problem-solving. Variations of the game exist, including simplified versions for beginners. Keelegu remains a lesser-known but historically rich component of Korean gaming traditions.
