Abstract: A deck of playing cards and a card game to be played therewith comprises a plurality of transparent cards each having the same outer shape and size. Each card carries a colored area which may correspond to a primary shape, a secondary shape, a tertiary shape or a large master shape. Primary, secondary and tertiary shapes are selected so that they can be combined in various ways to make the master shape. The colors which may also be transparent are selected so that overlapping master shapes of secondary colors can be combined to form primary colors. The game using the cards is similar to the card game known as casino where cards are retrieved by matching shapes rather than card values and where building and doubling can be practiced.
