Abstract: Apparatus for playing a board game, the apparatus comprising a board (2) with a playing surface marked with a first array of parallel rows (3) of playing positions (1), and a second array of parallel rows (4) of playing positions (1) extending transversely to the first array of rows (3) and with common playing positions where the rows of the two arrays cross over one another. At least some of the rows (3, 4) are sub-divided by barriers (7) into sections (3, 4) of playing positions (1). Four distinguishable sets of playing pieces are provided, each playing piece having one of a number of different indicia thereon. The indicia are arranged to form a predetermined sequence, the playing pieces of each set having the same group of indicia and at least a majority of the indicia being duplicated in each set.
