Connect6 Rules


Connect6 is a two-player game where the first player to connect exactly six pieces in a row—orthogonally or diagonally—wins. You try to win by creating situations where you can connect multiple groups of pieces simultaneously, preventing your opponent from blocking all of your openings on his next move.


The standard Connect6 board size is 19x19. Igfip™ supports a range of smaller and larger board sizes as well as rectangular boards and obstructed spaces.

Initial Connect6 board position.  Alternative Connect6 board position.

As in Go and Go-Moku, pieces are placed on the line intersections, not within the board squares.


Each player starts with no pieces on the board, but has an unlimited supply of pieces to place on the board.


  1. Black moves first by placing a single piece anywhere on the board.
  2. After the first move, each player places two of his pieces on any two empty board spaces before passing play to his opponent.
  3. The game ends when a player connects a line of exactly six contiguous pieces, orthogonally or diagonally. The first player to do so wins. If no player can win, the game ends in a draw.
