Four-field kono () is an abstract strategy game from Korea for two players. Each player attempts to capture the other player's pieces by jumping over their own piece and landing on the other player's piece.
Although the game is often described as being medieval, this assertion does not seem to be backed by evidence. It has, however, been recorded as being played from the late 19th century onwards. There are additional Korean two-player kono games with similar names and equipment, including well kono () and five-field kono (), but the boards, gameplay, and objectives for each are different. Culin mentions the existence of a six-field kono but does not provide further details.
The goal of each player is to capture the other player's pieces and reduce it to one, at which point - with only one piece - a player can no longer execute a capture. Another way to win is for a player to immobilize the other player's pieces so that they cannot move or capture.
The board is a 4ÃÂ4 square grid. There are 16 markers in total, divided into two equal sets of eight pieces each. Typically the game is played with eight black and eight white marbles.
The game is played according to these rules.
