Card game

A card game comprising a set of cards;

• each card being formed with a slit along its mid-line starting from one edge and extending for about one-half its width towards its opposite edge such as to permit each card to be inserted via its slit into the slit of each other card in the set to form a pair with one-half of one card aligned with and exposed to view with the other half of the other card;
• the slit in each card being formed with outwardly tapered edges to facilitate inserting one card into another;
• each card having indicia on each half of the card on opposite sides of its respective slit;
• the indicia on the half of each card on one side of the slit being non-validly complementary with the indicia on the other half of the card on the other side of its slit, but being validly complementary with the indicia on some, but not all, of the other cards of the set to form a valid card pair therewith when the two cards are inserted into each other via their respective slits.
