From the box: "60 cards with colored shapes on a see through background. Different parts of each card are colored in such a way that when the right cards are held together they make a solid image that cannot be seen through. Sometimes two cards are needed, sometimes 3, 4 or 5. The game is especially suited to help develop the faculties of concentration, observation and combination. Adults will find fascinating entertainment as the game provides ample scope for tactics." For 3 to 6 players, also possible for 1 player.
