Havannah rules:

  • The game starts on an empty board. Players move in turn to place one stone on an empty cell. White moves first. The second player is entitled to swap sides after White's initial move.
  • The game is won by the first player to complete a ring or a bridge or a fork. All of these are ``chains'' - closed connections of one color.
    • A ring is a chain around at least one cell.
    • A bridge is a chain linking two corners.
    • A fork is a chain linking three sides. Corners do not belong to sides.

That's it. In New Rules for Classic Games, Wayne states that a ring should surround at least one vacant cell. This is not the case - the cell may be occupied by either player.
