Gomoku

Classic game from ancient China

Gomoku, also called Five in a Row, is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a Go board. Because pieces are typically not moved or removed from the board, gomoku may also be played as a paper-and-pencil game. The game is known in several countries under different names.

Rules

Players alternate turns placing a stone of their color on an empty intersection. Black plays first. The winner is the first player to form an unbroken chain of five stones horizontally, vertically, or diagonally.

Variants

Gomoku

  • Played on a 19x19 board.
  • The first black stone is always in the center.
  • Black’s second stone must be outside the marked restricted region shown in the app.
  • A line of five or more stones wins.
  • If the game reaches 150 moves without a winner, Little Golem declares a draw.

Gomoku Pro

  • The game is played on a 15x15 board.
  • The first player opens by placing 1, 2, 3, 4, or 5 stones.
  • The stones in that opening alternate colors, starting with black.
  • The second player may accept the colors or play swap.
  • After the opening and optional swap, players place one stone per turn.
  • A line of five or more stones wins.
  • There is no draw. If the player to move can no longer make any five-in-a-row anywhere on the board, that player loses.
