 The number of holes in each row is rather arbitrary; instead of the 16+17+16 used in the Danish game, 12+13+12 are used in Norway, with 12 pieces for each player.In either case, there is no obvious reason for the extra hole in the middle row, other than to distinguish the two ends of the board, which is necessary to define the direction of play.The game is simple, and one will soon realise that it pays to have dalled pieces waiting in the home row close to the prow, and also in the enemy row behind all enemy pieces.
