Competitive game

The game utilizes a plurality of polygonal playing pieces e.g. in the form of blocks or cards or three dimensional and rules governing the placing of the pieces in a side by side relationship or in a one on top of the other relationship. The playing of pieces may represent the establishment of relationships between players or may represent players gambling on the fortunes of players who have already played pieces to represent relationships. The pieces are designed so that markings on the underneath surface thereof are invisible to players of the game when the pieces have been placed on a playing surface. The rules provide for scores to be allocated to players, dependent on the placing of pieces and the subsequent revealing of the markings on the underneath of some or all of the pieces - the markings or absence of markings underneath are termed 'positive', 'negative' or neutral edges. The game may involve deals between players but a player may decide secretly not to cooperate in a deal. Pieces may be triangular, square, hexagonal, pyramids, cubes and game may involve different forms - playing pieces of different players may be indentified by colour and/or shape.
