From the publisher: A new exciting strategy game promoting color and shape recognition. Vivid and shining tiles, painted with water colors, to be placed on a natural bamboo mat for great fun and learning experience. The game is played on 4x4 square mats with pieces shaped like squares, triangles, hexagons and circles. The object is to place the pieces so that only one of each shape is in a row or column, similar to Sudoku, except with shapes and on a smaller grid.
